Background and Objectives: There are many well-described approaches to symptomatic ventral hernia management; however, there remains a significant patient population with limited options for a durable ventral hernia repair with a reasonable risk of infection and recurrence. Drawing from the orthopedic literature, we changed our approach to this clinical problem and developed a palliative ventral hernioplasty pathway. Materials and Methods: A retrospective review (2017–2019) of patients’ palliative ventral hernioplasty was performed. Results: In total, 43 patients included, with a female preponderance of 24 (58.6%) and a mean age 61.5 ± 11.5 years. The mean BMI was 38.1 kg/m² (IQR: 25.4–62), and 28 patients (65.1%) had a history of prior wound/mesh infection. Urgent repair was performed in 14 patients. Overall polypropylene prosthetic was implanted in 26 patients, and bioprosthetic/absorbable mesh was used in the remaining. The mean surface area of the implanted mesh was 561 cm². The most common wound complications identified were skin separation (30.2%) and seroma formation (48.8%). Hernia recurrence occurred in four (9.3%) patients, with a mean follow-up of 24.1 months (9–37). Three patients had central lightweight mesh rupture and one had a recurrence (bioprosthetic mesh); all were subsequently repaired. Conclusions: Despite the small number of patients, our palliative ventral hernia repair pathway offers durable repair with an acceptable risk of recurrence and mesh infection in patients who would otherwise be considered nonoperative.

Background: Marfan syndrome is an autosomal dominant connective tissue disorder that affects multiple organ systems, with cardiovascular complications posing a major risk. With advancements in medical care and the increasing lifespan of patients with Marfan syndrome, the spectrum of medical issues has evolved. This case report highlights the complex anaesthetic management of a patient with Marfan syndrome during elective ventral hernia repair. Case presentation: A 37-year-old male with Marfan syndrome was admitted for elective open ventral hernia repair. Challenges included severe arterial hypertension, prior aortic valve replacement, scoliosis, and an anticipated difficult airway, as the patient presented with restricted mouth opening due to craniofacial abnormalities consistent with difficult laryngoscopy. Preoperative assessments included routine tests, echocardiography and chest X-ray. The anaesthetic management focused on specific patient positioning with head-up tilt, maintenance of haemodynamic stability with the insertion of an arterial line before the induction of anaesthesia and neuromuscular block (NMB) monitoring, followed by titrated doses of all medications. Lung ventilation strategies were specifically adjusted to address the patient’s underlying comorbidities. The patient was extubated and transferred to the recovery unit. The intraoperative and immediate postoperative periods were relatively uneventful. Dyspnea due to external pressure on the abdominal wall caused by a specific binder was treated with the release of pressure. Later postoperative recovery was complicated by hydrothorax and pneumonia, both treated successfully. Conclusions: This case emphasises the importance of multidisciplinary approaches and vigilant monitoring in the management of a patient with Marfan syndrome perioperatively, even for seemingly low-risk operations. Appropriate anaesthetic management helped to avoid major perioperative complications. Full article

Background: Inguinal hernioplasty in the pediatric population is a common minor injury operation. Whether the surgical approach alters perioperative stress responses remains uncertain. The aim of this study was to compare early inflammatory and endocrine stress markers after open (OIH) and laparoscopic inguinal hernioplasty (LIH). Methods: A single-center prospective observational study with 1:1 allocation between 2021 and 2023. Otherwise healthy children, scheduled for elective unilateral indirect inguinal hernia repair, were assigned to open or laparoscopic hernioplasty. Blood samples were collected at five time points, measuring levels of white blood cells, cortisol, MDA, ferritin, albumin, and CRP. Analyses used two-way repeated measures ANOVA with Greenhouse–Geisser correction and Bonferroni-adjusted planned contrasts at 24 h. Results: Thirty-two children aged from 2.4 months to 11 years with a mean age of 3.8 years (± 2.46 Standard Deviation, SD) were randomized equally. Operative times were longer in the laparoscopic group [01:07 (±00:20-SD)]; [open group operative duration: 00:41 (±00:16-SD), (p < 0.01)]; discharge on postoperative day 1 was universal. The group × time interaction was not significant for CRP, cortisol, MDA, albumin, or ferritin. WBC showed a modest interaction consistent with an earlier postoperative rise after laparoscopy (p = 0.006). No surgical site infections or recurrences occurred over a 2-year follow-up. Conclusions: This study demonstrates that LIH and OIH in children have a comparable impact on the inflammatory response. LIH is a safe and effective alternative to the traditional open repair method regarding operative stress. To validate these findings and assess the long-term implications of each surgical approach on children’s pathophysiology, further research is warranted. Full article

Background and Objectives. Umbilical hernia is particularly common among patients with liver cirrhosis, affecting about 20% of this group, compared to 3–8.5% in healthy individuals. This increased prevalence is mainly due to weakened abdominal fascia, elevated intra-abdominal pressure, and malnutrition. The rapid progression of umbilical hernias often leads to complications such as skin necrosis, perforation, and strangulation. Historically, patients with liver cirrhosis and complicated umbilical hernia have faced high morbidity and mortality rates. However, recent advancements in perioperative management, especially in controlling ascites, have improved outcomes in elective treatments. Despite these advancements, managing patients with decompensated liver cirrhosis and complicated umbilical hernia in emergency settings remain a significant surgical challenge. Materials and Methods: We conducted a retrospective review of patients treated for complicated umbilical hernia at the University Medical Centre Ljubljana from 2015 to 2024, using prospectively collected data. This analysis involved implementing hernioplasty combined with incisional negative pressure wound therapy (iNPWT) as part of the surgical protocol. The primary endpoint of our study was the rate of local complications, while the secondary endpoints included the rate of systemic complications and 90-day mortality. Results: We treated 28 consecutive patients with complicated umbilical hernia and liver cirrhosis. Local wound complications were observed in three (10.7%) patients. Systemic complications developed in 10 patients (35.7%). The median duration of hospitalization was 8 days (range: 5–29), and no readmissions were recorded within the 30-day period. Two (7.1%) patients died within 90 days. Conclusions: Our experience indicates that iNPWT, when combined with surgical repair, can be safely utilized, yielding outcomes comparable to elective hernia repairs, even in emergency contexts. Further randomized controlled trials are necessary to validate these findings and optimize treatment protocols. Full article

Tension-free hernioplasty has effectively reduced postoperative recurrence and mitigated complications by employing polymer patches. However, clinically used polymer patches often fall short in terms of the anti-deformation, anti-adhesion, and tissue integration functions, which can result in visceral adhesions and foreign body reactions after implantation. In this study, a Janus three-layer composite patch was developed for abdominal wall defect repair using a combination of 3D printing, electrospraying, and electrospinning technologies. On the visceral side, a dense electrospun polyvinyl alcohol/sodium hyaluronate (PVA/HA) scaffold was fabricated to inhibit cell adhesion. The middle layer, composed of polycaprolactone (PCL), provided mechanical support. On the muscle-facing side, a loose and porous electrospun nanofiber scaffold was created through electrospraying and electrospinning, promoting cell adhesion and migration to facilitate tissue regeneration. Mechanical testing demonstrated that the composite patch possessed excellent tensile strength (23.58 N/cm), surpassing the clinical standard (16 N/cm). Both in vitro and in vivo evaluations confirmed the patch’s outstanding biocompatibility. Compared with the control PCL patch, the Janus composite patch significantly reduced the visceral adhesion and enhanced the tissue repair in animal models. Collectively, this Janus composite patch integrated anti-deformation, anti-adhesion, and tissue-regenerative properties, providing a promising solution for effective abdominal wall defect repair.

Background and goal of study: The aim of this double-blind randomized study was to investigate the efficacy of dexmedetomidine as an adjuvant to the local anesthetic in transversus abdominis plane (TAP) block for unilateral inguinal hernioplasty. Materials and Methods: Eighty eligible patients were randomly allocated into ultrasound-guided TAP block with either dexmedetomidine 0.5 mcg/kg diluted to a volume of 2 mL and ropivacaine 0.5% 25 mL (DR group) or ropivacaine 0.5% 25 mL and normal saline 2 mL (R group). The primary endpoint of this study was the numeric rating scale (NRS) score during coughing 24 h postoperatively. Secondary parameters were also evaluated. Results: Patients in the RD group demonstrated significantly less pain at rest three, six and 12 h postoperatively as compared to patients in the R group (p = 0.002, 0.032 and 0.049, respectively). Significant differences between the two groups were also demonstrated for NRS scores during coughing at 3, 6 and 12 h postoperatively (p = 0.013, 0.035 and 0.042, respectively). Additionally, the RD group demonstrated lower intraoperative remifentanil consumption (p < 0.001), lower PACU morphine requirement (p = 0.012) and lower overall PCA morphine requirement postoperatively (p < 0.001). Sedation scores, the incidence of hypotension, bradycardia and the occurrence of postoperative nausea and vomiting were no different between the two groups. Finally, the incidence of chronic pain at 6 months was significantly lower in the RD group compared to the R group (5.55% vs. 25%, p = 0.049). Conclusions: Dexmedetomidine as an adjuvant to ropivacaine reduces postoperative pain scores, has opioid-sparing effects and is associated with a favorable effect on chronic pain without side effects in patients subjected to TAP block for inguinal hernia repair.

This article compares the antibacterial properties of single-layer (Ag) and two-layer (Ag,Cu) coatings deposited onto a polypropylene mesh (endoprostheses for hernioplasty) in various gaseous environments (argon or nitrogen) via magnetron sputtering. The microstructure and elemental composition of the coatings were studied via SEM and TEM. The antimicrobial activity of sterile samples was investigated using the Staphylococcus aureus strain. To prevent the overheating of the polymer samples during the coating process, it is advisable to carry out pulse processing (the total coating formation time is divided into cycles of switching the magnetron on and off for equal periods). All the samples, with both single- and double-layer coatings, exhibited good antibacterial properties; however, the Cu–Ag coating enhanced the antimicrobial effect, increasing it from 97.00 to 99.97%. The glow-discharge plasma etching of the samples with a double-layer coating led to the mixing of the copper and silver layers and an increase in the surface copper content, though this did not affect the antibacterial properties of the samples.

A new surgical technique using a polyether ether ketone (PEEK) anchoring device for testicle-sparing laparoscopic inguinal hernioplasty in stallions was described in 2023 and is known as the PEEK harpoon technique (PHT). In breeding stallions, it is essential that the surgery is effective in preventing inguinal hernia but also that it does not impair the testicular function. This study aims to evaluate whether the PHT may affect testicular function. To achieve that, changes in the testicular blood flow, sperm production and motility characteristics were assessed 28 days after use of the PHT. Standing laparoscopic hernioplasty using the PHT was performed unilaterally in eight healthy (non-previously herniated) experimental intact males. The contralateral inguinal canals and testicles were used as control. Pre- and post-surgery Doppler ultrasonographic evaluations of testicular perfusion were performed serially. Bilateral castration was performed at 28 days post-surgery, and epididymal sperm were obtained from both testicles to analyze seminal characteristics. No significant differences were identified in regard to testicular perfusion and the sperm characteristics of the control and operated testicles, suggesting that the PHT-based hernioplasty would not compromise testicular function. Further studies evaluating effects over a longer period are needed, but our data indicate that the PHT is suitable for testicle-sparing inguinal laparoscopic hernioplasties in breeding stallions with a history or predisposing factors of inguinal herniation.

Background/Objectives: Different analgesic techniques have been used in the clinical management of chronic post-hernioplasty pain (CPHP), with variable results. This study aimed to investigate clinical factors associated with long-term outcome of the transversus abdominal plane (TAP) block for CPHP. Methods: We retrospectively analyzed 26 patients with CPHP who were treated with single or multiple TAP blocks with local anesthetic and steroid. Patients were evaluated for pain and neuropathic pain intensity by a Numerical Rating Scale (NRS) and the painDETECT questionnaire (PDQ), for anxiety and depression by the Hospital Anxiety and Depression Scale, and for quality of life by the 12-item Short Form Health Survey (SF12). Results: At 6 months post-treatment, 20 patients (77%) presented substantial (>50%) or moderate (30–50%) CPHP relief and were considered responders. In responders, the 24-h average and maximum NRS pain significantly declined (p < 0.01) from 7.3 ± 1.3 to 2.6 ± 2.1 and from 8.8 ± 1.5 to 5.1 ± 2.0, and the neuropathic PDQ score from 9.1 ± 3.2 to 6.1 ± 1.3; the physical SF12 score improved from 36.5 ± 5.8 to 44.3 ± 7.5 (p < 0.01). Six patients failed to achieve a significant CPHP improvement and were considered non-responders. Non-responders presented a significantly (p < 0.05) longer CPHP, higher body mass index and neuropathic symptoms, and more frequent anxiety, depression, diabetes, and fibromyalgia. Conclusions: The TAP block with local anesthetic and steroid should be considered as a therapeutic option for CPHP. However, medical and psychiatric comorbidities negatively impact the TAP block effectiveness for CPHP. Full article

Inguinal hernias (IHs) and ruptures are a relatively common condition in horses, occurring in foals (congenital) and adult (acquired) animals. A retrospective observational analysis was conducted on 40 cases that underwent laparoscopic surgery to close the VRs using barbed sutures alone or combined with other techniques. Signalment, clinical presentation, surgery, and follow-up data were obtained. In total, fifty-nine VRs were closed using barbed sutures (alone or in combination with other methods), with six cases performed prophylactically and forty-four due to acquired IH. Of the forty-four cases with IH, four were non-strangulated hernias, while thirty presented with strangulated small intestines (twenty-eight acquired and two congenital). The results obtained in this study suggest that laparoscopic hernioplasty with barbed sutures is an effective and safe surgical procedure that could be recommended as a standard practice for managing inguinal hernias in horses, particularly when sparing testicles or preserving reproductive capabilities is a priority.

The aim of this study is to evaluate a laparoscopically assisted percutaneous suture (LAPS) procedure to treat inguinal hernia (IH) while preserving testicles in rams. An ex vivo experiment with six ram cadavers and a report of three clinical cases are discussed. In cadavers, both internal inguinal rings (IIR) were partially closed by LAPS. Two LAPS methods were tested: (1) using a laparoscopic portal closure device and (2) using a suture loop inserted through needles in each IIR. After each procedure, the closure was laparoscopically evaluated and the number of U- sutures was recorded. The procedure was also performed on three client-owned rams with unilateral non-strangulated IH and the occurrence of re-herniation was followed up. In cadavers, LAPS of the IIRs could be easily and satisfactorily performed with either of the two systems, requiring one to three U-sutures per IIR. No differences were observed between the two surgical procedures. In two clinical cases, the procedure was successfully performed without reoccurrence of herniation or alterations in reproductive behavior in the following 3 and 6 months. In the third case, the hernia was reduced but a retroperitoneal emphysema during laparoscopy prevented hernioplasty and the animal herniated again. In conclusion, LAPS of IIR can be used as a simple and feasible treatment to preserve testicles in rams with IH. Full article

Background: Umbilical hernia is one of the most common developmental defects in swine, producing large economic losses for farmers, forced to slaughter animals at a younger age and therefore at a lower weight to prevent fatal complications. This study describes a surgical technique to repair umbilical hernia through the use of autologous prostheses, allowing recovery of the affected animals; Methods: After a general examination of the swine and examination of the lesions, the swine were anesthetized and underwent surgery. The surgery was performed by combining the traditional herniorrhaphy with the inclusion and fixation of a peritoneal flap obtained from the incision of the same hernial sac; Results: Follow-ups were carried out at 7, 30 and 60 days and demonstrated healing in all of the treated subjects; Conclusions: The use of this surgical technique allows for providing resistance to herniorrhaphy performed through the use of a cost-free autologous biomaterial prosthesis, with excellent tissue compatibility. This might allow for reducing significantly the rate of relapses and eliminating the risk of rejection. Full article

(1) Purpose: To compare and evaluate the immediate and long-term results of the use of various hernioplasties for the treatment of inguinal hernias after surgical treatment of prostate cancer; to determine the possibility of performing transabdominal preperitoneal (TAPP) hernioplasty and total extraperitoneal (eTEP) hernioplasty in patients with inguinal hernia during surgical treatment of prostate cancer. (2) Method: This study is a clinical analytical prospective study, without the use of randomization. The study included 220 patients with inguinal hernia, who were randomly divided into two groups (group A (n = 100) and group B (n = 120)). Patients in group A received eTEP, and those in group B received TAPP. The end points of the study were the results associated with the operation itself and the prognosis of the disease in the two groups. (3) Results: Group A: five patients had a scrotal hematoma, in 10 cases nosocomial pneumonia or infectious complications from the postoperative wound. The overall rate of early postoperative complications was 15%. In group B, the following postoperative complications were reported: one case of intestinal injury, six cases of acute urinary retention, eight cases of scrotal hematoma and 12 cases of nosocomial pneumonia or infectious complications from the postoperative wound were admitted. The overall incidence of early postoperative complications was 22.5%. There was no statistically significant difference in the incidence of postoperative complications between the two groups (χ² (3) = 2.54, p > 0.05). (4) Conclusion: During the analysis of the obtained results, no statistically significant difference was found in the duration of hospitalization, the volume of blood loss, the severity of pain syndrome, postoperative complication incidence and recurrence incidence (p > 0.05); however, the comparison groups differed in the duration of the operation: the operation time in group A was much longer compared to group B (p < 0.05).

This study aimed to report the surgical outcomes of laparoscopic glue hernioplasty (LGH) compared with conventional laparoscopic suture hernioplasty (LSH) in pediatric female inguinal hernia repair. We retrospectively analyzed 465 female pediatric patients who underwent laparoscopic inguinal hernia repair between January 2013 and December 2020. LGH and LSH were performed in 95 and 370 cases, respectively. Surgical outcomes (length of hospital stay, operative time, complications, and recurrences) were compared between the LGH and LSH groups. We found that the operation times for bilateral hernia repair were shorter in the LGH group (LGH: 35.5 ± 8.2 min, LSH: 45.2 ± 11.6 min; p < 0.001). No significant differences in complications or recurrences were observed between the two groups during the follow-up period. Our findings suggest that LGH is a feasible and easily applied surgical technique for the treatment of pediatric female inguinal hernia. Full article

Extended cultivation with multiple removal of BC pellicles is proposed herein as a new biosynthetic process for bacterial cellulose (BC). This method enhances the BC surface area by 5–11 times per unit volume of the growth medium, improving the economic efficiency of biosynthesis. The resultant BC gel-films were thin, transparent, and congruent. The degree of polymerization (DP) and elastic modulus (EM) depended on the number of BC pellicle removals, vessel shape, and volume. The quality of BC from removals II–III to VII was better than from removal I. The process scale-up of 1:40 by volume increased DP by 1.5 times and EM by 5 times. A fact was established that the symbiotic Medusomyces gisevii Sa-12 was adaptable to exhausted growth medium: the medium was able to biosynthesize BC for 60 days, while glucose ran low at 24 days. On extended cultivation, DP and EM were found to decline by 39–64% and 57–65%, respectively. The BC gel-films obtained upon removals I–VI were successfully trialed in experimental tension-free hernioplasty. Full article
