Objective: Minimally invasive surgery in Hirschsprung disease (HSCR) management was introduced in the mid-1990s. Despite decades of clinical application of various laparoscopic approaches, there remains a paucity of high-powered prospective studies and comprehensive systematic reviews in the literature. This study aimed to systematically review and summarize published techniques and outcomes of laparoscopic- and robotic-assisted surgery in HSCR. Methods: A systematic literature review was conducted using PubMed and the Cochrane Library. Studies reporting technical and outcome data of laparoscopic- or robotic-assisted surgery for HSCR were included. Data extraction and analysis were performed in accordance with the PRISMA 2020 guidelines. Parameters of interest included surgical technique, age at primary pull-through (PT), operative time, and functional outcomes. Outcomes of laparoscopic- versus robotic-assisted Yancey–Soave PT were compared. Results: A total of 700 publications were screened, of which seven studies met the inclusion criteria. Data from 556 patients were analyzed. A total of 338 underwent laparoscopic-assisted, and 218 underwent robotic-assisted pull-through. Large variability of the reported transanal resection technique (modified Yancey–Soave PT) was reported. Four studies reported functional outcomes in patients aged over four years. Three studies directly compared laparoscopic- and robotic-assisted PT; two reported no difference in the incidence of postoperative Hirschsprung-associated enterocolitis (HAEC). Functional outcomes were assessed using the Krickenbeck classification in three studies and the bowel function score in one study, with no significant differences reported in patients aged >4 years. Conclusions: Laparoscopic- and robotic-assisted Yancey–Soave PT appears to be safe for HSCR. Large variability in the applied surgical technique—despite being commonly classified as modified Yancey–Soave PT—as well as heterogeneity in the bowel function assessment, limit direct comparability between studies. To date, no single minimally invasive approach has demonstrated clear superiority over others. Prospective, randomized controlled studies are required to enable robust comparative evaluation of techniques, overall costs, and outcomes. Full article

Background/Objectives: Robot-assisted partial nephrectomy (RAPN) has increasingly replaced laparoscopic partial nephrectomy (LPN) in the management of localized renal tumours. This study aimed to evaluate perioperative, functional and surgical margin outcomes during an institutional transition from LPN to RAPN in a high-volume centre. Methods: We performed a retrospective single-centre analysis of 100 consecutive patients undergoing minimally invasive partial nephrectomy. The last 50 LPN cases (August 2014–May 2018) were compared with the first 50 RAPN cases (June 2018–February 2020). Baseline characteristics, perioperative outcomes, early functional parameters and surgical margin status were analysed. Complications were classified according to the Clavien–Dindo system. Results: Tumours treated in the RAPN group were significantly larger (3.4 vs. 2.5 cm) and more complex (RENAL score of 6 vs. 5; p < 0.001). Operative time was longer in the RAPN group (143 vs. 122 min; p < 0.01), while warm ischaemia time did not differ significantly (16 vs. 15 min; p = 0.37). Estimated blood loss was lower (0 vs. 10 mL; p = 0.049) and the hospital stay was shorter (3 vs. 4 days; p < 0.001) in the RAPN group. Haemoglobin decrease and postoperative creatinine change were comparable between groups. Positive surgical margins were observed less frequently in the RAPN group (2.3% vs. 7.7%), but this difference was not statistically significant (p = 0.34). Complication rates were significantly lower in the RAPN group (4% vs. 22%; p < 0.05), with no major complications observed in the robotic cohort. Conclusions: In this institutional experience, RAPN was associated with favourable perioperative outcomes during the transition period, despite the treatment of larger and more complex renal tumours. The slightly longer operative and warm ischaemia times likely reflect a more comprehensive reconstruction strategy, which may contribute to improved haemostatic control and lower complication rates. Further studies with extended follow-up are required to evaluate oncological and renal functional outcomes. Full article

Background: Endometrial cancer is the most common gynecologic malignancy in North America, with over 8000 new diagnoses in 2022 alone. Surgical management is the mainstay of treatment, with a shift towards the use of minimally invasive surgery, including laparoscopic and robotic techniques. Therefore, our study aims to compare the surgical and oncologic outcomes of hysterectomy approaches for patients with endometrial cancer. Methods: We have used a retrospective design to review all the endometrial cancer cases from Kingston Health Sciences Centre between January 2017 and November 2022. Variables were collected and categorized. Surgical outcomes were compared based on the route of surgery. Kaplan–Meier and Cox proportional hazard models were used to compare recurrence-free and overall survival. Results: A total of 341 cases were included in this review. One-hundred-fifty-two (44.6%) of these cases were minimally invasive surgeries (total laparoscopic, laparoscopic-assisted vaginal and robotic-assisted hysterectomies) and 189 (55.4%) were open hysterectomies. The early complication rates (p < 0.001) and length of stay (p < 0.001) were lower in the laparoscopic group. Despite the abdominal group including more advanced cases, there were no differences in recurrence-free and overall survival between the groups (p = 0.39; p = 0.85). Conclusions: Minimally invasive hysterectomy approaches result in improved surgical outcomes, while oncologic outcomes remain similar across techniques. Full article

Background/Objectives: Sentinel lymph node (SLN) biopsy is a minimally invasive alternative to systematic lymphadenectomy for endometrial cancer staging. However, optimization of SLN identification during robot-assisted surgery remains an important clinical issue. This prospective exploratory study evaluated the feasibility and mapping characteristics of dual-tracer SLN mapping combining radioisotope (RI) and indocyanine green (ICG) in robot-assisted surgery for clinical stage IA endometrial cancer. Methods: Ten patients with clinical stage IA endometrioid carcinoma (grade 1 or 2) who underwent robot-assisted surgery at our institution between June 2025 and March 2026 were prospectively enrolled. Technetium-99m phytate was injected cervically the day before surgery, followed by SPECT-CT imaging. ICG was administered intraoperatively. SLNs were identified using both RI mapping and near-infrared fluorescence imaging. All patients subsequently underwent pelvic lymphadenectomy. SLN detection rates, concordance between tracers, intraoperative findings, and perioperative outcomes were evaluated. Results: The SLN detection rate with the dual-tracer method was 100% (10/10). RI mapping alone achieved bilateral detection in 30% (3/10), whereas ICG fluorescence imaging identified SLNs in all patients (100%). All RI-positive SLNs were also identified by ICG fluorescence imaging. In several cases, multiple fluorescent lymph nodes were observed, and gamma-probe assessment aided intraoperative SLN selection. No lymph node metastases were identified. One Clavien–Dindo grade IIIa complication (pelvic hematoma requiring intervention) occurred. No adverse events related to ICG were observed. Conclusions: Dual-tracer SLN mapping using RI and ICG was feasible in robot-assisted surgery for clinical stage IA endometrial cancer. ICG fluorescence imaging provided sensitive lymphatic visualization, whereas RI mapping offered complementary information for intraoperative SLN identification in selected cases. Further prospective studies with larger cohorts are required to clarify the clinical utility of the dual-tracer approach. Full article

Background: Deep infiltrating endometriosis (DIE), particularly when involving the bowel, significantly impairs health-related quality of life (HRQoL) and gastrointestinal function. This study aimed to evaluate the short- and mid-term impact of minimally invasive excision on these parameters in a large multicenter cohort. Methods: A retrospective observational study was conducted on 837 patients treated for endometriosis in two tertiary referral centers between 2018 and 2024. All patients underwent laparoscopic or robotic-assisted excision. Quality of life was assessed preoperatively and at 6 months (VAS: n = 69; SF-36: n = 100; GIQLI: n = 98) and 12 months (VAS: n = 30; SF-36: n = 46; GIQLI: n = 44) postoperatively, using validated patient-reported outcome measures (PROMs): the Visual Analog Scale (VAS) for pain, the Short Form-36 (SF-36) survey, and the Gastrointestinal Quality of Life Index (GIQLI). Results: The study population presented with predominantly advanced disease (Stage III–IV in 83.4% of cases), with 39.7% of patients undergoing segmental bowel resection. Postoperatively, a statistically significant reduction was observed in dysmenorrhea (VAS 7.6 vs. 5.0, p < 0.001) and chronic pelvic pain. The SF-36 scores improved significantly across all eight domains at 6 months, with the most dramatic recovery seen in Role Physical (p < 0.001) and Bodily Pain (p < 0.001). Regarding digestive function, the mean GIQLI score showed a progressive increase, reaching statistical significance at 12 months compared to baseline (112.6 vs. 106.6, p = 0.027), indicating superior long-term functional outcomes. Conclusions: Multidisciplinary minimally invasive surgery for deep infiltrating endometriosis was associated with significant and sustained improvements in quality of life among patients with available follow-up. Gastrointestinal quality of life, as measured by GIQLI, improved significantly at 12 months postoperatively, including in patients who underwent segmental bowel resection. Systematic use of PROMs is essential for accurate patient counseling and outcome monitoring. Full article

Background: Robot-assisted radical prostatectomy (RARP) is the predominant surgical approach for localized prostate cancer in high-volume centers worldwide. However, comprehensive real-world data describing complete institutional transition from open to robotic surgery remain limited. This study evaluated perioperative and early oncological outcomes of a contemporary RARP cohort and characterized the transition from open radical prostatectomy (ORP) to RARP in a European center. Methods: We analyzed 520 consecutive patients who underwent RARP between January 2023 and December 2025. Perioperative, pathological, and biochemical outcomes were assessed. Biochemical recurrence was defined as prostate-specific antigen ≥0.2 ng/mL. Institutional data from 2011 to 2025 were reviewed to evaluate procedural trends and the transition from ORP to RARP. Surgeon-specific and institutional learning curves were analyzed using operative time and linear regression models. Results: Following the introduction of robotic surgery in 2018, annual RARP volume increased from 37 procedures to 205 in 2025. Since 2023, RARP accounted for more than 99% of all radical prostatectomies. Median operative time decreased from 185 min in 2023 to 165 min in 2025, with consistent downward trends observed across all surgeons. Linear regression confirmed progressive improvement in operative efficiency, with learning rates ranging from −0.22 to −0.92 min per case. Estimated blood loss was minimal, no patients required transfusion, and major complications occurred in four patients (0.8%). Hospital stay decreased from 2 days to predominantly 1 day. During follow-up, 36 patients developed biochemical recurrence or PSA persistence. Biochemical recurrence-free survival differed significantly according to pathological stage (log-rank p < 0.001), with 24-month estimates of 93.7%, 91.5%, and 82.1% for pT2, pT3a, and pT3b disease, respectively. Conclusions: RARP provides favorable perioperative safety, minimal morbidity, and favorable early oncological outcomes in a high-volume setting. The complete institutional transition from ORP to RARP, together with demonstrated surgeon-specific and institutional learning effects, supports the feasibility and safety of implementing RARP as the institutional standard within a structured robotic program.

The adoption of neoadjuvant immune checkpoint inhibitor (ICI)-based chemoimmunotherapy has fundamentally transformed the operative landscape of resectable non-small cell lung cancer (NSCLC). Surgeons are now routinely confronted with ICI-altered tissue planes characterized by hilar fibrosis, vascular friability, and disrupted lymph node architecture. Simultaneously, robotic-assisted thoracic surgery (RATS) has consolidated its position as the dominant minimally invasive platform for pulmonary resection, accounting for the majority of lobectomies and segmentectomies performed at high-volume centers in 2023. Whether RATS confers specific technical advantages in this increasingly complex operative context remains incompletely characterized. We conducted a structured narrative review of published evidence, synthesizing data from randomized controlled trials, prospective cohorts, national registry analyses, and emerging technology reports addressing RATS in the setting of neoadjuvant ICI-based therapy for NSCLC. A systematic literature search was conducted across PubMed and EMBASE using predefined search terms. Available evidence, though largely retrospective and limited by small sample sizes, consistently demonstrates that RATS after neoadjuvant chemoimmunotherapy is technically feasible and oncologically sound, with R0 resection achievable in virtually all cases. The enhanced three-dimensional visualization, tremor filtration, and instrument degrees of freedom afforded by robotic platforms appear particularly advantageous in the setting of dense hilar adhesions and fragile pulmonary vasculature. Lymph node yield, a recognized robotic advantage, is preserved or enhanced despite post-ICI fibrosis. Pooled conversion rates to thoracotomy, derived from post hoc surgical analyses of ICI trial populations rather than trials designed to measure conversion, are higher than for upfront resection; available retrospective single-center data, including one direct RATS-versus-VATS comparison, suggest lower conversion rates with RATS in experienced hands, though this conclusion requires prospective validation. Emerging platform integrations, including combined robotic bronchoscopy and thoracoscopic surgery, single-port systems, and artificial intelligence-assisted anatomical navigation, are poised to further extend the reach of minimally invasive surgery in this challenging clinical scenario. In experienced centers, RATS appears to offer a technically favorable minimally invasive platform for pulmonary resection after neoadjuvant ICI-based therapy, with potential advantages over VATS in managing immunotherapy-altered anatomy; however, this conclusion is derived from retrospective series and should be interpreted cautiously pending prospective comparative data. Prospective multicenter trials with standardized surgical endpoints are urgently needed. Full article

The introduction of minimally invasive surgery (MIS) marked a turning point in the history of medicine, driving one of the sharpest declines in surgical mortality and morbidity ever recorded—saving millions of lives and sparing an estimated one billion patients the suffering once inherent to large-incision surgery. Within a single generation, this once highly contested surgical innovation became the global standard of care, transforming surgical practice across disciplines and on a global scale. By every measure of public health, these outcomes place modern minimally invasive and robotic-assisted surgery as among the most consequential life-saving advances in modern medical history. This review examines the clinical impact and global dissemination of MIS, tracing its evolution from Camran Nezhat’s pioneering expansion of laparoscopy beyond diagnostics to complex therapeutic procedures across surgical disciplines. Drawing on decades of evidence across gynecology, general surgery, and urology, we show that MIS is associated with substantial reductions in perioperative mortality, major complications, blood loss, infections, thromboembolic events, postoperative pain, and length of hospital stay, while maintaining oncologic equivalence and improving functional and quality-of-life outcomes. Beyond these technical advances, MIS catalyzed a broader reimagining of surgery itself, challenging long-standing norms rooted in large-incision approaches and shifting the field toward precision, organ preservation, and pathology-directed intervention. These changes were accompanied by parallel advances in multiple domains, including in imaging, intraoperative visualization technologies, surgical anatomy, instrumentation, and nerve- and organ-sparing techniques—developments that collectively established the foundation for contemporary minimally invasive and robotic-assisted surgery. Collectively, these advances have contributed to the prevention of an estimated 10–20 million surgery-related deaths that would likely have occurred under the large-incision approaches of the past.

Background: Robotic-assisted bronchoscopy enables precise navigation to peripheral pulmonary lesions and expands minimally invasive diagnostic options in thoracic surgery. At our institution, the ION™ Endoluminal System (Intuitive Surgical, Sunnyvale, CA, USA) was introduced to improve diagnostic accuracy in challenging peripheral targets. It is widely recognized that a defined number of procedures is required to achieve procedural proficiency and optimal clinical outcomes when adopting a novel platform. Therefore, this retrospective single-center study aimed to evaluate the learning curve associated with the implementation of this technology in a thoracic surgery center. Methods: In this retrospective study, all consecutive patients who underwent robotic-assisted bronchoscopies performed using the ION™ Endoluminal System (Intuitive Surgical, Sunnyvale, CA, USA) for the diagnosis of peripheral pulmonary lesions between August 2024 and March 2026 were analyzed. A total of 128 lesions in 89 patients were initially identified. Cases involving marker placement without diagnostic biopsy, as well as procedures not performed by the primary operator, were excluded. After applying exclusion criteria, 109 procedures in 76 patients were included. The mean patient age was 65.4 ± 9.1 years, and 44 patients were female (57.9%). To assess the learning curve, procedures were chronologically divided into three groups: early (cases 1–36), intermediate (37–73), and late (74–109). Outcome measures included procedure time, number of biopsies per lesion, tumor size, and diagnostic yield. Group comparisons were performed using non-parametric and chi-square tests. Procedural learning was assessed by cumulative sum (CUSUM) analysis of procedure time. Results: The overall diagnostic yield was 85.3% (93/109). The diagnostic yield increased over time from 73.0% in the early phase to 83.3% in the intermediate phase and 94.6% in the late phase. The overall comparison was statistically insignificant (χ2 p = 0.117); however, there was a significant linear trend across phases, indicating progressive improvement with exposure to the application of this technology. Procedure time decreased significantly from a median of 49.0 min in the early phase to 31.0 min in the intermediate phase and 30.0 min in the late phase (p < 0.001). At the same time, the number of biopsies per lesion increased significantly (p < 0.001). Tumor size did not differ significantly between groups (p = 0.170). Conclusions: Robotic-assisted bronchoscopy demonstrates a clear learning curve, characterized by increasing diagnostic yield and significantly reduced procedure time during the implementation phase. The technique can be effectively integrated into the thoracic surgical diagnostic workflow and represents a valuable addition to minimally invasive diagnostics for peripheral pulmonary lesions.

Robotic assistance in minimally invasive surgery has significantly improved precision and dexterity; however, many supportive tasks, such as blood aspiration, still rely on manual operation. This work presents the design and implementation of a supervised autonomous robotic aspirator for detecting and removing bleeding in an in vitro experimental model. The proposed system integrates a perception module based on a convolutional neural network for real-time blood segmentation, a task planner for high-level action execution, and a control strategy based on artificial potential fields for autonomous navigation. Additionally, a mixed-reality human–robot interaction interface is incorporated to enable system supervision and seamless transition to teleoperation when required. The system was experimentally validated with a set of in vitro experiments under three representative bleeding scenarios, evaluating four suction strategies based on the computation method for the target selection. Results demonstrate high blood removal rates (above 80% in all cases) and high suction efficiency. The comparative analysis reveals that the performance of the suction strategies is scenario-dependent and highlights a trade-off between suction efficiency and removed area. These findings support the feasibility of autonomous robotic aspiration and provide insights into the design of adaptive strategies for surgical assistance, contributing toward increased task autonomy and reduced need for continuous manual suction control during minimally invasive procedures.

Minimally invasive spine surgery (MISS) has progressively transformed the management of spinal disorders by reducing soft-tissue disruption, perioperative morbidity, and recovery time while maintaining clinical outcomes comparable to conventional open techniques. Beyond its technical evolution, MISS has increasingly assumed a central role in the treatment of bone-related spinal conditions, including vertebral fractures, degenerative instability, metastatic disease, and osteoporosis-associated pathology. This narrative review provides a comprehensive overview of the evolution of MISS with a specific focus on its interaction with vertebral bone biology, implant stability, and fusion processes. A structured literature search of the PubMed/MEDLINE database was conducted, including English-language studies published between 1980 and June 2025 addressing MISS techniques, enabling technologies, and bone-related clinical outcomes. Current evidence suggests that MISS may preserve paraspinal vascularization and soft tissue integrity, potentially supporting bone healing and fusion, although high-quality comparative data remain limited. The effectiveness of MISS in osteoporotic and metastatic vertebral disease is closely linked to bone quality, implant anchorage, and biomechanical considerations, particularly in the context of pedicle screw fixation and interbody support. Emerging technologies—including navigation, robotics, and artificial intelligence—may enhance accuracy in implant placement and reduce bone-related complications, but robust evidence of long-term benefit is still lacking. Despite its advantages, MISS presents important limitations, including a steep learning curve, increased costs, and uncertain superiority in terms of fusion rates and long-term biomechanical stability. Future research should prioritize high-quality comparative studies focusing on bone healing, implant integration, and patient-specific factors such as bone density. MISS should therefore be interpreted not only as a surgical paradigm shift but as an evolving strategy for optimizing outcomes in bone-related spinal disorders. Full article

Background/Objectives: Robot-assisted surgery (RAS) has grown rapidly over the past few decades. To determine the effect of high stress levels on the performance of RAS, monitoring some parameters of surgeons is critical. This can be aided by the development of Artificial Intelligence (AI), which has exponentially grown in recent years. This study aims to predict the surgeon’s stress level based on ergonomic, kinematic and physiological parameters of the surgeon obtained in the immediately previous situation during RAS activities. Methods: Physiological data were recorded from surgeons during twenty-six surgical sessions involving twelve participants with different levels of experience and surgical specialties. After dataset generation, two preprocessing procedures (scaling and normalization) were applied to the recorded signals. The processed data were then partitioned into two subsets: 80% of the samples were used for model training and cross-validation, while the remaining 20% were reserved for testing. Six AI approaches were evaluated to build predictive models: multiple linear regression (MLR), a support vector machine (SVM), a multilayer perceptron (MLP), a convolutional neural network (CNN), random forest (RF), and a U-Net algorithm (UNET). These algorithms were trained using the training dataset and subsequently assessed on the independent test set. In addition, after each surgical session, surgeons completed a questionnaire reporting their perceived stress level, which was later compared with the stress estimates generated by the predictive models. Results: The results obtained showed that MLR and scaling pre-processing reached the highest R2 coefficients and the lowest error for each studied parameter. The results of the surgeons’ surveys were highly correlated for microsurgery activities (R2 = 0.7989) and for laparoscopy RAS (R2 = 0.8381). Conclusions: The linear models proposed were correctly validated on cross-validation and the test dataset. This fact demonstrates the possibility of predicting factors that help us to improve the surgeon’s health during RAS. Full article

Thin-slice high-resolution computed tomography (CT) has improved the detection of small pulmonary nodules, increasing the demand for minimally invasive diagnostic and therapeutic resection. While lobectomy with lymph node dissection remains the standard surgical approach for many patients with resectable non-small cell lung cancer, accumulating evidence supports sublobar resection for selected small, peripheral, and ground-glass-dominant lesions when sufficient margins are achievable. In thoracoscopic and robotic surgery, localization of nodules ≤10 mm or lesions located >5 mm from the pleural surface can be challenging, and failure to identify the target may lead to conversion, larger resection than intended, or prolonged operative time. Several localization strategies have been developed, including CT-guided percutaneous wire/coil/dye marking, bronchoscopic dye mapping, and virtual-assisted lung mapping (VAL-MAP), robotic-assisted bronchoscopic dye or fiducial localization, radiofrequency identification microtag systems (Surgical Real-Time FInger Navigation and Detection) that provide real-time depth information, and single-stage intraoperative CT-guided marking and resection in hybrid operating rooms. This review synthesizes representative evidence and published outcome ranges, and compares workflows, marker-to-lesion precision metrics, complication profiles, operational burden, and cost structures. We emphasize the practical contrast between two-stage and single-stage workflows, the access-route differences between transthoracic and transbronchial techniques, and the need to report localization-to-incision “time at risk”. We also present an expert-consensus decision algorithm aimed at facilitating tailored selection of localization strategies for modern minimally invasive thoracic surgery. Full article

Background/Objectives: Well-leg compartment syndrome is a rare but potentially life-threatening complication associated with the lithotomy position during pelvic or lower abdominal surgery. While previous studies have examined this condition in specific surgical fields, comprehensive studies focusing on minimally invasive surgery, including laparoscopic and robot-assisted surgery, have not been conducted. This scoping review aimed to summarize the latest evidence on this condition, identify risk factors, and evaluate prevention strategies. Methods: This scoping review was conducted according to the PRISMA-ScR guidelines. A comprehensive literature search was performed using MEDLINE, Embase, and CENTRAL. Data were extracted from studies focusing on patients who underwent minimally invasive surgery in the lithotomy position. Results: A total of 25 studies, including cohort studies and case reports, were included. The majority of cases were observed in procedures exceeding 4 h in duration, with a notable prevalence in the left lower extremity during gastrointestinal surgical procedures. Fasciotomy was required in the majority of reported cases. Risk factors included high body mass index, large calf circumference, prolonged operative time, peripheral vascular disease, and specific surgical positions such as head-down or head-down plus right-sided tilting. Preventive measures included intraoperative lower limb pressure monitoring, leg positioning, use of improved support devices, and reduction of operative time in the lithotomy position. Conclusions: This review identified key risk factors and preventive measures for compartment syndrome of the unaffected lower limb in minimally invasive pelvic surgery. However, evidence for minimally invasive surgery is limited, and standardized guidelines do not exist. Further multicenter studies are needed to establish optimal preventive measures and improve patient safety. Full article

Soft robotics is a rapidly evolving field that has attracted significant attention within the scientific community. This review analyzes the main advantages of pneumatic technology in service robots across the different application domains defined by the International Federation of Robotics (IFR). By organizing the literature according to application domains, this work aims to clarify the specific benefits of pneumatic and soft pneumatic solutions in each context. The proposed approach distinguishes between traditional pneumatic solutions and the subsequent emergence of soft robotics, in order to highlight how and to what extent soft technologies have reshaped the design and application scenarios. Particular attention is devoted to the role of materials and recent manufacturing techniques used by researchers to fabricate soft pneumatic robots. Based on 163 selected papers, the analysis reveals that medical and agricultural applications dominate soft pneumatic research, accounting for 41% and 27% of the soft sample, respectively. Compared to traditional pneumatics, the medical sector has expanded into cardiac assistive devices, wearable monitoring sensors, and minimally invasive surgery; agriculture has grown from 17% to 27% of the soft literature due to precision harvesting grippers. Soft inspection robots have increased thanks to continuum manipulators and bio-inspired locomotion, while search and rescue remains a niche (9%) but promising sector. Unlike previous reviews that focus on single domains or technologies, this work quantifies the uneven transition from rigid to soft pneumatics across IFR sectors and highlights emerging application-specific design paradigms that were not feasible with traditional systems.
