Background: Migration of the peritoneal end of the ventriculoperitoneal shunt (VPS) into the scrotum is a rare but recognized complication. Inguinoscrotal migration typically occurs as a result of increased intra-abdominal pressure combined with a patent processus vaginalis. A 14-month-old pediatric patient presented to the emergency department with abdominal pain, vomiting, and swelling of the right scrotum that had persisted for two days. The patient had a history of a head injury that had resulted in a large secondary arachnoid cyst for which a VPS had been placed at eight months of age. Examination of the inguinoscrotal region revealed a swollen and painful right side of the scrotum with a hydrocele and a palpable distal portion of the ventriculoperitoneal catheter in the right groin extending to the scrotum. After a brief preoperative preparation, the patient underwent laparoscopic abdominal emergency exploration, during which shunt repositioning and laparoscopic closure of the patent processus vaginalis were performed. Methods: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results: A total of 30 case reports and six case series were included, analyzing 52 pediatric patients with scrotal migration of the VPS. The median age at presentation was 24 months (range: 1–169 months). The indication for VPS placement was hydrocephalus. Migration of the VPS catheter occurred on the right side in 34 cases. The median interval from VPS placement to the onset of symptoms was 9.0 months (range: 1 day–72 months). The most frequently reported symptoms were scrotal/inguinoscrotal swelling (n = 50), vomiting (n = 7), and fever (n = 3). Diagnostic methods included abdominal X-ray (n = 43), ultrasound (n = 5), scrotal transillumination test (n = 5), and computed tomography (n = 1). Regarding treatment, surgical repositioning of the VPS catheter into the peritoneal cavity was performed in 47 patients (90.4%), with no intraoperative or postoperative complications reported. Conclusions: Laparoscopic repositioning of the VPS into the peritoneal cavity, combined with closure of the processus vaginalis, appears to be a safe and effective treatment option for scrotal migration of the VPS. However, further well-designed studies are warranted to provide more comprehensive, generalizable, and unbiased evidence regarding this complication in the pediatric population. Full article

Background: Hydatid disease, caused by the larval form of Echinococcus granulosus, is a rare but potentially life-threatening condition during pregnancy, with an estimated incidence of 1 in 20,000 to 30,000 gestations. Physiological immunosuppression and increased placental steroid levels during pregnancy may promote cyst growth, elevating the risk of rupture, which can result in anaphylactic shock, sepsis, or widespread peritoneal dissemination. Diagnostic imaging, particularly ultrasonography, plays a central role in detection, while treatment decisions are complicated by the lack of standardized guidelines and the need to balance maternal–fetal safety. Methods: This case report describes a 29-year-old pregnant woman at 22 weeks’ gestation who was incidentally diagnosed with two large hepatic hydatid cysts during a routine ultrasound. Results: Given the high rupture risk, she underwent successful laparoscopic surgery in the second trimester, followed by careful monitoring and elective cesarean delivery at term. A third retroperitoneal cyst, initially managed conservatively, was excised postpartum. Conclusions: This case highlights the critical importance of individualized, multidisciplinary management in achieving favorable maternal and neonatal outcomes in complex presentations of hydatid disease during pregnancy.

Pancreatic cancer is an aggressive malignancy, with a current 5-year survival rate in the United States of approximately 13.3%. Although the current standard for resectable pancreatic cancer most commonly includes neoadjuvant chemotherapy prior to a curative resection, surgery, in the majority of patients, has historically been palliative. The latter interventions include open or laparoscopic bypass of the bile duct or stomach in cases of obstructive jaundice or gastric outlet obstruction, respectively. Non-surgical interventional therapies started with percutaneous transhepatic biliary drainage (PTBD), both as a palliative maneuver in unresectable patients with obstructive jaundice and to improve liver function in patients whose surgery was delayed. Likewise, interventional radiologic techniques included the placement of plastic and ultimately self-expandable metal stents (SEMSs) through PTBD tracts in patients with unresectable cancer as well as percutaneous cholecystostomy in patients who developed cholecystitis in the context of malignant obstructive jaundice. Endoscopic retrograde cholangiopancreatography (ERCP) and stent placement (plastic/SEMS) were subsequently used both preoperatively and palliatively, and this was followed by, or undertaken in conjunction with, endoscopic gastro-duodenal SEMS placement for gastric outlet obstruction. Although endoscopic ultrasound (EUS) was initially used to cytologically diagnose and stage pancreatic cancer, early palliation included celiac block or ablation for intractable pain. However, it took the development of lumen-apposing metal stents (LAMSs) to facilitate a myriad of palliative procedures: cholecystoduodenal, choledochoduodenal, gastrohepatic, and gastroenteric anastomoses for cholecystitis, obstructive jaundice, and gastric outlet obstruction, respectively. In this review, we outline these procedures, which have variably supplanted surgery for the palliation of pancreatic cancer in this rapidly evolving field. Full article

Endometriosis is a clinical entity affecting up to 10% of women of reproductive age, characterized by ectopic endometrial tissue outside the uterine cavity. While extrapelvic endometriosis has been documented, pancreatic endometriosis remains extremely rare and poses significant diagnostic challenges due to its similarity to other pancreatic diseases. At the same time, splenic mesothelial cysts are also rare and typically benign. This report presents a unique case of pancreatic endometriosis coexisting with a splenic mesothelial cyst in a 31-year-old woman. The patient presented to the emergency department with complaints of persistent epigastric and low back pain. She noted having similar symptoms approximately a year prior. Her past medical history was otherwise unremarkable, and there was no known family history of pancreatic disease or neoplasms. Initial imaging revealed a 3.8 cm cystic lesion in the pancreatic tail, with features suggestive of mucinous cystadenoma. Following clinical evaluation and confirmation of the cyst’s nature through endoscopic ultrasound-guided biopsy, the patient subsequently underwent laparoscopic distal pancreatectomy and splenectomy due to worsening symptoms. Gross examination revealed a multilocular pancreatic cyst with a smooth, hemorrhagic wall. Microscopic analysis showed the cyst to be lined by cuboidal to columnar epithelium, consistent with pancreatic endometriosis, confirmed by immunohistochemical staining. The spleen showed cystic formations, diagnosed as a multifaceted mesothelial cyst. In conclusion, this report is the first to document the coexistence of pancreatic endometriosis and splenic mesothelial cysts, highlighting the importance of accurate imaging and pathologic evaluation in the diagnosis of these rare conditions. Early diagnosis and surgical intervention lead to favorable outcomes, reinforcing the importance of comprehensive diagnostic strategies. Full article

This manuscript examines the role of artificial intelligence (AI) in the diagnosis and treatment of uterine fibroids and uterine sarcomas, offering a comprehensive assessment of AI-supported diagnostic and therapeutic techniques. Through the use of radiomics, machine learning, and deep neural network models, AI shows promise in identifying benign and malignant uterine lesions, directing therapeutic decisions, and improving diagnostic accuracy. It also demonstrates significant capabilities in the timely detection of fibroids. Additionally, AI improves surgical precision, real-time structure detection, and patient outcomes by transforming surgical techniques such as myomectomy, robot-assisted laparoscopic surgery, and High-Intensity Focused Ultrasound (HIFU) ablation. By helping to forecast treatment outcomes and monitor progress during procedures like uterine fibroid embolization, AI also offers a fresh and fascinating perspective for improving the clinical management of these conditions. This review critically assesses the current literature, identifies the advantages and limitations of various AI approaches, and provides future directions for research and clinical implementation.

Background: Upper abdominal surgeries exceeding two hours and operated in a lateral decubitus position present an “intermediate” risk for pulmonary complications. The objectives of this study were to observe the sonographic and clinical changes during and after surgeries with one recruitment maneuver (RM) performed intraoperatively before extubation. Methods: Laparoscopic nephrectomy patients were randomized into pre-extubation single RM (Group RM) and control (Group NoRM) groups. The LUS (Lung Ultrasound Score) was evaluated after intubation (T1), at the end of surgery before the RM (T2), after the RM but before extubation (T3), and 30 min after arrival to the Post-Anesthesia Care Unit (T4) in Group RM; in Group NoRM, it was evaluated at the T1, T2, and T4 time points. The primary outcome was the effect on the pre-extubation LUS (T2 in Group NoRM versus T3 in Group RM). The secondary outcomes included the effects on the T4 LUS, PPC occurrence, and PaO₂/FiO₂ ratios, and the sensitivity and specificity of the LUS in predicting PPCs. Results: The data of 54 patients were analyzed. The pre-extubation LUS was significantly lower in Group RM (16 (12.5, 17) vs. 18 (17, 20), p < 0.001). The T4 LUS was only different in the upper zones in the dependent lung (2 (1, 3.5) in Group RM vs. 4 (3, 4.5) in Group NoRM, p = 0.01). The perioperative PaO₂/FiO₂ ratios were similar (p > 0.05). The pre-extubation LUS exhibited 91% sensitivity (p = 0.04), whereas the T4 LUS sensitivity was 82% (p = 0.01). The PPC risk was 10-fold higher in patients with a pre-extubation LUS exceeding 19. Conclusions: A pre-extubation single RM instantly increases the LUS. However, this does not persist postoperatively or diminish respiratory complications. More importantly, the LUS was found to be a sensitive tool for predicting PPCs when performed just before extubation. Full article

Introduction: Congenital duodenal atresia (DA) (Type I) with a fenestrated web can be characterized by a late presentation with a delayed diagnosis. It is even rarer and usually associated with proximal duodenomegaly. Conventional management involves web resection and duodeno–duodeno anastomosis with or without duodenoplasty. We describe our mininvasive surgical strategy and management, detailing the aspects of laparoscopic techniques. Material and Methods: We retrospectively reviewed the medical records of five patients affected by fenestrated duodenal web (DA) with a delayed onset of symptoms and diagnosis who were managed in our Department over a period of 10 years (2013–2023). We analyzed the age of patients at diagnosis, clinical signs and symptoms, associated congenital anomalies, radiological and intraoperative findings, surgical treatment, and outcomes. Diagnostic examinations included ultrasound (US), Upper-Gastrointestinal Study (UGI), and Esophagogastroduodenoscopy (EGDS). Results: Three boys and two girls, median age of 5.5 months (range 3–11 months), were included in this study. Three underwent previous surgery for long-gap esophageal atresia (EA), two of Type A, and one of Type C, requiring a gastrostomy immediately after birth (delayed esophageal repair for prematurity in Type C) and subsequent delayed primary anastomosis. Major associated anomalies were EA (3), anterior ectopic anus (1), cloaca (1), and Type IV laryngeal web (1). An antenatal diagnostic suspicion of duodenal atresia (obstruction) on ultrasound was described in two patients. UGI suggested a fenestrated duodenal web, visualized at ultrasound in two patients. Duodenal dilation was associated in two cases. The symptoms were feeding difficulties, nonbilious vomiting, upper abdominal distension, and poor growth. All presented with a pre-ampullary obstruction. Endoscopic confirmation was only possible in one patient. The older patient underwent an endoscopic resection of a duodenal web. In the other four, we performed a laparoscopic longitudinal antimesenteric duodenal incision, web resection (excision), and transverse suture (closure was performed) without duodenoplasty. Intraduodenal Indocyanine Green (ICG) visualization (under near-infrared light) was used in the last two cases. No postoperative complications were recorded, with a mean hospital stay of 8 days. A contrast study performed at 4 weeks demonstrated an improved proximal duodenal profile; patients tolerated a full diet and remained symptom-free. Conclusions: According to our experience with minimally invasive techniques, laparoscopy and endoscopy are effective and safe, supporting web resection for the management of a duodenal web without tapering of the proximal duodenum. They require advanced technical skills. Intraduodenal-ICG injection during laparoscopic treatment of Type 1 DA allows localization of the duodenal web, confirmation of bowel patency (bowel canalization) and the tightness of suture.

Iatrogenic ureteral strictures are uncommon but challenging to manage. We present our expertise in laparoscopic and robot-assisted laparoscopic ureteroureterostomy (LUU and RAUU) for lumbar and iliac strictures and laparoscopic ureteral reimplantation for pelvic strictures. A descriptive study was conducted on nine adult patients who underwent minimally invasive procedures. Six had lumbar or iliac ureteral strictures—five due to ureterorenoscopy and one following pancreaticoduodenectomy for pancreatic cancer. Three developed pelvic strictures after ureterorenoscopy. Preoperative evaluation included a medical history review, abdominal ultrasound, and CT scan. Success was characterized by the absence of symptoms and the lack of obstruction on follow-up imaging at one year. All procedures were technically feasible, with a median operating time of 105 min and a median hospital stay of four days. No major complications occurred. One patient experienced ureteral stricture recurrence following a laparoscopic approach for a lumbar stricture, and required a permanent double-J stent. At a median follow-up of 38 months, 88.88% of patients remained asymptomatic with preserved renal function. Our findings suggest that robotic and laparoscopic ureteral reconstruction performed by experienced surgeons at a tertiary center is a safe and effective option with a low complication rate.

Background and Objectives: Quadratus lumborum block (QLB) is a regional anesthesia technique widely utilized in multimodal analgesia strategies for abdominal surgeries. While a few studies have investigated its efficacy in multiport total laparoscopic hysterectomy (TLH), its effectiveness in single-port TLH remains uncertain. This study aimed to evaluate whether QLB reduces opioid consumption and postoperative pain in patients undergoing single-port TLH. Materials and Methods: This randomized, controlled, observer-blinded trial included 64 patients undergoing elective single-port TLH. Participants were randomly allocated to either the QLB group (n = 27) or the control group (n = 29). QLB was performed bilaterally under ultrasound guidance after surgery. The primary outcome was cumulative fentanyl consumption within 24 h postoperatively. Secondary outcomes included pain scores at predefined intervals, time to first opioid demand, the incidence of postoperative nausea and vomiting (PONV), and other complications. Results: The 24 h cumulative fentanyl consumption, which was the primary outcome, did not differ significantly between the QLB group, 342.8 [220, 651] mcg, and the control group, 470 [191.6, 648.1] mcg (p = 0.714). Similarly, cumulative fentanyl consumption at other time points, including 2 h, 4 h, 8 h, 12 h, 32 h, and 48 h, as well as in the PACU, also showed no significant differences between the two groups. Pain scores measured at these time points, along with the time to first bolus on demand, were comparable between groups. However, PONV occurred more frequently in the QLB group than in the control group (25.9% vs. 3.4%, p = 0.023). Conclusions: QLB did not significantly reduce opioid consumption, time to first opioid demand, or postoperative pain scores in single-port TLH. However, PONV occurred more frequently in the QLB group. These findings suggest that QLB may have limited analgesic benefits in single-port TLH. Full article

Background: This study aimed to evaluate the advantages of integrating intraoperative ultrasound (IOUS) into laparoscopic adrenal surgery by assessing its impact on perioperative outcomes and identifying potential complications. Methods: This retrospective study analyzed 128 patients with adrenal gland tumors who underwent a laparoscopic adrenalectomy by comparing those who received intraoperative ultrasound guidance with those who did not. The procedures were performed using either the transperitoneal or the lateral retroperitoneal approach. Results: The IOUS-guided group had significantly lower blood loss (p < 0.001) and a shorter hospitalization duration (p = 0.005) compared with the non-IOUS group. No intraoperative complications were observed in the IOUS group, whereas three complications occurred in the non-IOUS group, including peritoneal breaches and minor liver damage. The retroperitoneal approach demonstrated superior perioperative outcomes, with a shorter operative time (p < 0.001), reduced blood loss (p < 0.001), earlier resumption of oral intake and lower postoperative analgesia requirements (p < 0.001). Conclusions: Intraoperative ultrasound enhanced the surgical precision in laparoscopic adrenalectomy, which reduced the blood loss, shortened the hospital stays and minimized the intraoperative complications.

Median Arcuate Ligament Syndrome, also known as Dunbar’s syndrome, is a rare condition caused by stenosis of the celiac artery (CAS) through the fibrous arch connecting the diaphragmatic branches. It manifests as postprandial abdominal pain, nausea, vomiting, weight loss and increased epigastric tenderness. The condition most commonly affects young females without coexisting vascular comorbidities. Diagnosis is difficult due to the non-specific symptoms, often overlapping with other gastrointestinal diseases. Standard investigations include duplex ultrasound, computed tomography angiography (CTA) and contrast-enhanced magnetic resonance imaging (CE-MRA). Treatment mainly consists of surgical release of the arch ligament, which can be performed by open, laparoscopic or robotic methods. Surgery is often supported by celiac truncal stenting for residual stenosis, which significantly improves vascular flow. Alternative approaches include visceral plexus blocks and novel hybrid techniques, such as a combination of ligament release and endovascular treatment of the celiac trunk. In severe cases, vascular by-passes are recommended. The aim of this paper is to discuss the clinical manifestations, diagnostic possibilities, therapeutic options and directions for further research on MALS from the perspective of a vascular surgeon. It emphasizes the need for a multidisciplinary approach, including collaboration between the surgeon, radiologist, gastroenterologist and psychologist, which enables comprehensive disease management and improved quality of life for patients. In addition, the need for further development of diagnostic and therapeutic methods for early diagnosis and effective treatment was pointed out. Full article

Background: Bladder leiomyomas are rare benign tumors (<0.5% of all bladder tumors) arising from the bladder wall’s smooth muscle. Only 250 cases of this condition have been reported worldwide so far. While some leiomyomas present with irritative or obstructive symptoms, hematuria, or nonspecific abdominal pain, others are asymptomatic and are diagnosed incidentally. The surgical approach is based on the leiomyoma’s size and location. Given this tumor’s rarity, standardized management guidelines do not exist; however, transurethral resection of bladder tumor (TURBT), partial or radical cystectomy, or laparoscopic/robotic enucleation are viable therapeutic options. Case history: We report the case of a 64-year-old female presenting with recurrent colic and pelvic pain. An abdominal CT scan showed a 3 cm mass protruding from the posterior bladder wall toward the right vaginal fornix. A transvaginal ultrasound-guided through-cut biopsy confirmed the diagnosis of a bladder leiomyoma. Due to the tumor’s size and location, robotic enucleation was chosen to minimize the risk of bladder perforation. The mass was successfully excised via a transvesical approach. Results: The procedure was completed in 210 min without complications, with 50 mL blood loss. The patient recovered well, with resolution of symptoms and no recurrence at eighteen-month follow-up. Histopathological examination on the surgical specimen confirmed the diagnosis of bladder leiomyoma. Conclusions: This case highlights the feasibility and safety of robotic enucleation for large bladder leiomyomas, emphasizing minimal invasiveness, limited pelvic dissection, and preservation of bladder function. Further research and standardized guidelines are needed for managing this rare condition. Full article

This study aimed to evaluate the feasibility of single-port laparoscopic pancreatic exploration, laparoscopic ultrasonography, and pancreatic biopsy in dogs. Six clinically healthy Beagles (median age: 13 months; range: 12–30 months; median weight: 8.81 kg; range: 7.82–10.64 kg) with normal findings upon physical examination and no history of systemic disease underwent a single-port laparoscopic procedure via a paramedian incision. In all cases, pancreatic exploration was performed visually through laparoscopy but was limited to the right lobe and body of the pancreas due to anatomical constraints; the left lobe remained inaccessible. The median exploration time was 239 s for the right lobe and 370 s for the pancreatic body. After exploration, a laparoscopic ultrasound was performed on the parenchyma of the explored regions, successfully identifying major anatomical structures, including the cranial pancreaticoduodenal artery, vein, and major duodenal papilla. The median laparoscopic ultrasound evaluation time was 838 s (range: 729–878 s). A pancreatic biopsy was performed on the distal portion of the right lobe, yielding tissue samples of approximately 10 × 10 mm in size. No intra- or postoperative complications were observed. However, this study was conducted in healthy dogs; further validation is necessary to confirm its diagnostic utility. These findings demonstrate the feasibility of single-port laparoscopic exploration and laparoscopic ultrasonography-guided anatomical assessment. Full article

Mucinous cystic neoplasm of the liver (MCN-L) is a rare benign tumor accounting for less than 5% of all liver cysts, with MCN-L in the hilar region being exceptionally uncommon and often misdiagnosed due to its complex presentation. A 48-year-old woman presented with obstructive jaundice following initial laparoscopic drainage of hepatic cysts, where pathology initially indicated benign cystic lesions. Months later, imaging revealed an enlarged cystic lesion in the left liver lobe with intrahepatic bile duct dilation. Further evaluations, including ultrasound, enhanced CT, and MRI, confirmed a large cystic lesion compressing the intrahepatic bile ducts. After a multidisciplinary discussion, hepatic cyst puncture and drainage were performed, temporarily alleviating jaundice. However, she returned with yellowish-brown drainage fluid and worsening jaundice, prompting cyst wall resection. Postoperative pathology confirmed MCN-L. Three months later, jaundice subsided, and a hepatic resection of segment 4 was performed, with pathology confirming low-grade MCN-L. At a 12-month follow-up, the patient showed no abnormalities. This case highlights the diagnostic and therapeutic challenges of MCN-L in the hilar region, as it can easily be mistaken for other liver cystic lesions on imaging. Pathologic examination is essential for definitive diagnosis, and early radical surgical resection is critical to improve prognosis and reduce the risk of malignancy and recurrence. Full article

Background/Objectives: Current literature has demonstrated the benefits of transversus abdominis plane (TAP) blocks for reducing postoperative pain and opioid consumption for an array of surgical procedures. Some randomized controlled trials and retrospective studies have compared ultrasound guidance TAP blocks completed by anesthesiologists (US-TAP) to laparoscopic guidance TAP blocks completed by surgeons (LAP-TAP). However, the findings of these studies have not been consolidated to improve recommendations and patient outcomes. Our objective is to consolidate and summarize current literature regarding the efficacy of TAP blocks for postoperative pain control and opioid consumption when performed with ultrasound guidance (US-TAP, compared to laparoscopic guidance (LAP-TAP). Methods: We performed a systematic review and meta-analysis of RCTs and retrospective studies to evaluate US-TAP versus LAP-TAP blocks for postoperative pain control and opioid consumption. We searched PubMed/MEDLINE, CINAHL, Cochrane, and Web of Science databases for all articles meeting the search criteria until the time of article extraction in February 2024. The primary outcome variables were postoperative pain scores and opioid consumption. The secondary outcome variables were complications, time taken to perform the block, length of stay (LOS) in the hospital, and cost of performing the block. Results: Of the 1673 articles initially identified, 18 studies met the inclusion criteria for evaluation. Of the included studies, 88.9% and 77.8% found no significant difference in postoperative pain scores or opioid consumption, respectively, between US-TAP and LAP-TAP groups. Six studies (33.3%) found that LAP-TAP was faster to perform than US-TAP. Meta-analysis demonstrated no statistically significant differences in postoperative pain scores or opioid consumption between groups but showed that block times were significantly longer in the US-TAP group. Conclusions: US-TAP and LAP-TAP blocks may be equivocal in terms of reducing postoperative pain and opioid consumption. LAP-TAPs may be less time-consuming and more cost-effective and viable alternatives to US-TAP blocks in the perioperative setting. Full article
