A case of adrenal cavernous hemangioma resected due to tumor growth accompanied by intratumoral hemorrhage.

Introduction: We describe a case of an adrenal cavernous hemangioma that was surgically resected because of tumor growth and intratumoral hemorrhage. Case presentation: A 73-year-old woman presented with an enlarged adrenal tumor and intratumoral hemorrhage during the follow-up of an incidental adrenal tumor. A computed tomography showed that the left adrenal tumor had grown from 23 to 44 mm over 1 year. Blood tests revealed a normal metabolic profile. Paragangliomas and metastatic tumors were suspected on imaging. Laparoscopic adrenalectomy was performed to prevent tumor rupture due to further bleeding. No adhesions or bleeding were observed around the tumor during surgery. Pathological diagnosis was adrenal cavernous hemangioma. Conclusion: Adrenal cavernous hemangioma is difficult to distinguish preoperatively from other adrenal tumors, including malignant tumors. The intraoperative findings of this case suggest that laparoscopic adrenalectomy is a safe treatment option for relatively small adrenal cavernous hemangioma.

A case of spontaneous bladder rupture successfully conservatively treated with transurethral debridement and hyperbaric oxygen therapy.

Introduction: Spontaneous bladder rupture is a potentially life-threatening condition. Its treatment often requires invasive strategies, mainly surgical closure, or cystectomy. We present a case where we successfully treated bladder rupture employing a less invasive technique of transurethral debridement and hyperbaric oxygen therapy. Case presentation: A woman in her 80s presenting with lower abdominal pain was suspected of vesicoenteric fistula. Subsequent investigations confirmed bladder rupture to the abdominal wall, which eventually developed into a vesicocutaneous fistula. To minimize the invasiveness of treatment, a combined strategy of transurethral debridement of the fistula, and hyperbaric oxygen therapy was taken, resulting in successful outcome. Conclusion: Our approach was unique for its tolerability in comparison to conventional surgical approaches taken towards this condition.

Impact of minimally invasive surgery on immune function and stress response in gastric cancer patients.

BACKGROUND: Gastric cancer remains a leading cause of cancer-related mortality globally. Traditional open surgery for gastric cancer is often associated with significant morbidity and prolonged recovery. AIM: To evaluate the effectiveness of laparoscopic minimally invasive surgery as an alternative to traditional open surgery for gastric cancer, focusing on its potential to reduce trauma, accelerate recovery, and achieve comparable oncological outcomes. METHODS: This study retrospectively analyzed 203 patients with gastric cancer who underwent surgery at the Shanghai Health Medical College Affiliated Chongming Hospital from January 2020 to December 2023. The patients were divided into two groups: Minimally invasive surgery group (n = 102), who underwent laparoscopic gastrectomy, and open surgery group (n = 101), who underwent traditional open gastrectomy. We compared surgical indicators (surgical incision size, intraoperative blood loss, surgical duration, and number of lymph nodes dissected), recovery parameters (time to first flatus, time to start eating, time to ambulation, and length of hospital stay), immune function (levels of IgA, IgG, and IgM), intestinal barrier function (levels of D-lactic acid and diamine oxidase), and stress response (levels of C-reactive protein, interleukin-6, and procalcitonin). RESULTS: The minimally invasive surgery group demonstrated significantly better outcomes in terms of surgical indicators, including smaller incisions, less blood loss, shorter surgery time, and more lymph nodes dissected (P < 0.05 for all). Recovery was also faster in the minimally invasive surgery group, with earlier return of bowel function, earlier initiation of diet, quicker mobilization, and shorter hospital stays (P < 0.05 for all). Furthermore, patients in the minimally invasive surgery group had better preserved immune function, superior intestinal barrier function, and a less pronounced stress response postoperatively (P < 0.05 for all). CONCLUSION: Laparoscopic minimally invasive surgery for gastric cancer not only provides superior surgical indicators and faster recovery but also offers advantages in preserving immune function, protecting intestinal barrier function, and mitigating the stress response compared to traditional open surgery. These findings support the broader adoption of laparoscopic techniques in the management of gastric cancer.

Survival prognostic analysis of laparoscopic D2 radical resection for locally advanced gastric cancer: A multicenter cohort study.

BACKGROUND: With the development of minimally invasive surgical techniques, the use of laparoscopic D2 radical surgery for the treatment of locally advanced gastric cancer (GC) has gradually increased. However, the effect of this procedure on survival and prognosis remains controversial. This study evaluated the survival and prognosis of patients receiving laparoscopic D2 radical resection for the treatment of locally advanced GC to provide more reliable clinical evidence, guide clinical decision-making, optimize treatment strategies, and improve the survival rate and quality of life of patients. AIM: To investigate the survival prognosis and influencing factors of laparoscopic D2 radical resection for locally advanced GC patients. METHODS: A retrospective cohort study was performed. Clinicopathological data from 652 patients with locally advanced GC in our hospitals from December 2013 to December 2023 were collected. There were 442 males and 210 females. The mean age was 57 ± 12 years. All patients underwent a laparoscopic D2 radical operation for distal GC. The patients were followed up in the outpatient department and by telephone to determine their tumor recurrence, metastasis, and survival. The follow-up period ended in December 2023. Normally distributed data are expressed as the mean ± SD, and normally distributed data are expressed as M (Q1, Q3) or M (range). Statistical data are expressed as absolute numbers or percentages; the χ 2 test was used for comparisons between groups, and the Mann-Whitney U nonparametric test was used for comparisons of rank data. The life table method was used to calculate the survival rate, the Kaplan-Meier method was used to construct survival curves, the log rank test was used for survival analysis, and the Cox risk regression model was used for univariate and multifactor analysis. RESULTS: The median overall survival (OS) time for the 652 patients was 81 months, with a 10-year OS rate of 46.1%. Patients with TNM stages II and III had 10-year OS rates of 59.6% and 37.5%, respectively, which were significantly different (P < 0.05). Univariate analysis indicated that factors such as age, maximum tumor diameter, tumor differentiation grade (low to undifferentiated), pathological TNM stage, pathological T stage, pathological N stage (N2, N3), and postoperative chemotherapy significantly influenced the 10-year OS rate for patients with locally advanced GC following laparoscopic D2 radical resection for distal stomach cancer [hazard ratio (HR): 1.45, 1.64, 1.45, 1.64, 1.37, 2.05, 1.30, 1.68, 3.08, and 0.56 with confidence intervals (CIs) of 1.15-1.84, 1.32-2.03, 1.05-1.77, 1.62-2.59, 1.05-1.61, 1.17-2.42, 2.15-4.41, and 0.44-0.70, respectively; P < 0.05]. Multifactor analysis revealed that a tumor diameter greater than 4 cm, low tumor differentiation, and pathological TNM stage III were independent risk factors for the 10-year OS rate in these patients (HR: 1.48, 1.44, 1.81 with a 95%CI: 1.19-1.84). Additionally, postoperative chemotherapy emerged as an independent protective factor for the 10-year OS rate (HR: 0.57, 95%CI: 0.45-0.73; P < 0.05). CONCLUSION: A maximum tumor diameter exceeding 4 cm, low tumor differentiation, and pathological TNM stage III were identified as independent risk factors for the 10-year OS rate in patients with locally advanced GC following laparoscopic D2 radical resection for distal GC. Conversely, postoperative chemotherapy was found to be an independent protective factor for the 10-year OS rate in these patients.

Enucleation of insulinoma using laparoscopic distal pancreatectomy with a focus on vascular and splenic preservation: a case report.

Insulinomas represent <10% of pancreatic tumors. It is a functional neuroendocrine tumor that can cause recurrent and severe episodes of loss of consciousness due to hypoglycemia. Surgical removal is the only curative treatment. The selection of the optimal surgical technique must be individualized for each patient. Currently, there are emerging innovations in less invasive techniques that reduce morbidity. We present the case of a 23-year-old woman who underwent enucleation of an insulinoma localized at the tip of the pancreatic tail after laparoscopic surgery, with a focus on vascular and splenic preservation. The tumor was safely identified during surgery and enucleated without injury to the spleen and adjacent vascular structures or postoperative complications.

Outcomes of robotic versus laparoscopic-assisted surgery in patients with rectal cancer: a systematic review and meta-analysis.

PURPOSE: Robotic-assisted rectal surgery (RARS) and Laparoscopic-assisted rectal surgery are the two techniques that are increasingly used for rectal cancer, and both have their advantages and disadvantages. This meta-analysis will analyze the outcomes of both techniques to determine their relative performance and suitability. METHODS: An extensive search was carried out on PubMed, Cochrane, Scopus, Embase, and Google Scholar, followed by a meta-analysis of all randomized controlled trials (RCTs) to assess both approaches for rectal cancer. RESULTS: This meta-analysis is comprised of fifteen RCTs. The conversion to open surgery (RR = 0.53, 95% CI: 0.38-0.74, P = 0.0002) was significantly lower in the RARS group. The outcomes like anastomotic leak, postoperative ileus, postoperative urinary retention (POUR), surgical site infection (SSI), and intra-abdominal abscess showed no significant difference between the two groups. The reoperation rate (RR = 0.56, 95% CI: 0.34-0.95, P = 0.03) was lower in the robotic group. High heterogeneity was obtained when pooling data on operative time, length of hospital stay, and blood loss. Oncological outcomes, including local recurrence, the number of harvested lymph nodes (LN) and distal resection margin showed no significant distinction among both groups, while the positive circumferential resection margin (CRM) (RR = 0.67, 95% CI: 0.49-0.91, P = 0.01) was lower in the RARS group. RARS demonstrated a significantly higher rate of total mesorectal excision (TME) (RR = 1.07, 95% CI: 1.01-1.14, P = 0.03). CONCLUSION: RARS is safe and feasible for rectal cancer patients and may be superior or equivalent to Laparoscopic-assisted rectal surgery, but high-standard, large-scale trials are required to determine the best approach.

Early Experience With a Novel Super-Hydrophilic Laparoscopic Scope Cleaning Device and Narrative Review of Available Cleaning Strategies.

BACKGROUND: Impaired visibility is a challenge in laparoscopic surgery. Frequent scope removal increases operative time, reduces efficiency, and potentially compromises patient safety. We examine our initial experience with a novel cleaning device that applies cold plasma to the scope lens and review current available laparoscope cleaning methods. METHODS: The novel device was used in a variety of laparoscopic general surgery cases from April to November 2023. Primary outcome was number of scope removals per case. Secondary outcomes were time spent cleaning and number of times the scope became smudged or dirty with blood/tissue debris (debris events). An existing device that utilizes heated anti-fogging solution was used for comparison. RESULTS: 97 cases were included (31 with novel device and 66 with existing device). Scope removal rate for the novel device was lower compared to the existing device (0.87 ± 1.02 vs 0.97 ± 1.20 removals/case, P = 0.69), but not statistically significant. Average number of debris events was also lower for the novel device, but not statistically significant (0.90 ± 0.94 vs 1.0 ± 1.18 debris events/case, P = 0.69). Average total time spent cleaning per case was similar between devices (16.9 ± 24.0 vs 15.9 ± 18.7 seconds, P = 0.82). CONCLUSION: This study demonstrates that a hydrophilic scope cleaning device has comparable performance to heated anti-fogging solution and may reduce scope removals and debris events. Direct comparisons between cleaning products are lacking. Surgeons are most likely to be successful with the cleaning strategy that best suits one's surgical practice.

Current Practice of Laparoscopic Surgery for Choledochal Cyst in Children -a Survey on Opinion and Experience Among IPEG Members.

PURPOSE: Laparoscopic resection of choledochal cyst (CC) has become a popular approach. As the discussion about optimal treatment and technical strategies continues, we aimed to investigate perspectives of IPEG members. METHODS: An online survey was conducted in 2023 on behalf of the IPEG Research Committee. IPEG members were asked to complete an anonymous questionnaire that included 36 items on the management of CC. RESULT: 148 members responded to the survey (North America:49/Asia:44/Europe:23/South America:21/Others:11) and 116 completed all questions. Most surgeons (92.5%) operate on less than 5 cases annually. Diagnostic tools of choice were Magnetic Resonance Imaging (MRI, 95.9%) and ultrasonography (US, 74.5%). Regarding fusiform-type CC, operative indications were cyst size greater than 10 mm (68.9%), typical symptoms (78.5%), or anomalous pancreatico-biliary junction (63.8%). In unilateral intrahepatic biliary cysts (type IVa) cases, 81.3% of respondents do not perform a simultaneous liver resection with the initial cyst resection. While 22.0% resect the CC at diagnosis, even if asymptomatic, a larger group of surgeons (41%; 49/118) wait until the infant reaches six months. Intraoperative cholangiography and choledochoscopy are performed routinely by 38.9% and 13.7%, respectively. The majority (52.5%) ligates the common bile duct stump just below the CC. Laparoscopic reconstructions are performed by retrocolic hepatico-jejunostomy (48.3%) or hepatico-duodenostomy (45.8%) at similar rates, but when done open, 71.2% of respondents prefer retrocolic hepatico-jejunostomy. For the laparoscopic anastomosis, interrupted sutures with intracorporeal knot tying were most often utilized (48.3%). CONCLUSION: Inidividual pediatric surgeons treat a small number of patients with CC each year. Laparosopic and open reconstruction techniques vary, likely due to technical challenges. LEVEL OF EVIDENCE: III.

Six-year analysis of 30-day post-operative leaks for primary sleeve gastrectomy: a MBSAQIP database study.

BACKGROUND: Sleeve gastrectomy is the most performed bariatric surgery. Post-operative gastric sleeve leaks, although rare, are dreaded complications. This study aims to perform an updated investigation of the factors associated with sleeve leaks. METHODS: This retrospective cohort study analyzed 692,554 cases from the MBSAQIP database (2016-2021) with CPT code 43,775 for primary sleeve gastrectomy. We excluded emergency operations, conversions/revisions, endoscopic interventions, patient with prior foregut surgery, and open operations. Multivariate logistic regression analysis (STATA version 15) was performed to identify factors associated with sleeve gastrectomy leaks. RESULTS: Out of 692,554 patients, 600,910 (86.77%) patients underwent laparoscopic sleeve gastrectomy, and 91,644 (13.23%) patients underwent robotic sleeve gastrectomy. 1179 (0.17%) developed leaks within 30 days; 177(0.19%) were in the robotic group and 1002 (0.17%) in the laparoscopic group with no significant difference in leak rates between two groups on multivariate analysis. Black patients had lower odds of having leaks as compared to white patients (Odds Ratio (OR): 0.68 (0.56-0.82); p < 0.01). Hispanic patients had lower odds of having leak as compared to non-Hispanics. Factors associated with higher leak odds (p < 0.05) included hypertension, GERD, smoking, immunosuppression, increased operating time, and albumin < 3.5 g/dl. Higher odds of leaks were observed in years 2016-2019 vs 2020-2021 (OR: 1.44 (1.25-1.65), p < 0.01). Higher odds of leak in operations with general surgeons compared to bariatric surgeons was found (OR: 1.46 (1.04-2.02), p = 0.02); observed only on robotic group on subgroup analysis (OR: 2.2 (1.2-4.2), p = 0.02). Staple line reinforcement, oversewing, and performance of leak test showed no differences in leak rate. Bougie size and distance from pylorus were not associated with changes in leak rate. CONCLUSION: This study provides updated insights into the factors associated with sleeve leaks, reinforcing information gained from prior studies. A higher association of leak among general surgeons could represent a learning curve for new robotic general surgeons. The overall decreasing trend for gastric sleeve leak is encouraging and may be a sign of improved techniques.

Comparison of three umbilical entry sites for intraperitoneal access by the direct trocar insertion technique: a randomized pilot study.

Objective: The most effective methods and entry sites for laparoscopic surgery remain a subject of ongoing investigation and discussion. The purpose of the study was to analyze and compare three umbilical entry sites for intraperitoneal access using the direct trocar insertion technique. Material and Methods: A randomized pilot study was conducted between March 2021 and January 2023, involving women eligible for laparoscopic gynecological surgery. The women were allocated to one of three equally sized groups based on trocar entry points: subumbilical, supraumbilical, or umbilical. Success and failure rates of trocar entry, factors influencing success or failure, and early and late complications were systematically evaluated and compared across groups. Results: A total of 243 patients, with a mean age of 32.93±8.33 years, were included in three groups of 81 each. Trocar entry success rates were 97.5%, 89.2%, and 89.5% in the supraumbilical, umbilical, and subumbilical groups, respectively (p>0.05). Failed trocar entry was significantly associated with age, gravidity, body mass index (BMI), waist circumference, hip circumference, and abdominal subcutaneous fat thickness (p<0.001). Regression analysis revealed that, in the subumbilical group, higher gravidity [odds ratios (OR): 0.390, 95% confidence interval (CI): 0.174-0.872, p=0.022) and greater abdominal subcutaneous fat thickness (OR: 0.090, 95% CI: 0.019-0.431, p=0.03) were associated with lower odds of successful trocar entry. In contrast, in the umbilical group, a higher waist circumference was associated with lower odds of successful trocar entry (OR: 0.673, 95% CI: 0.494-0.918, p=0.012). None of the covariates were significant in the supraumbilical group. Conclusion: The study highlighted the importance of selecting the appropriate trocar entry site in laparoscopic gynecological surgery. Surgeons should consider factors such as age, gravidity, BMI, waist circumference, hip circumference, and abdominal subcutaneous fat thickness, as these factors significantly influence the success of trocar entry.

Intraoperative laparoscopic ultrasound during laparoscopic myomectomy: a narrative review.

Intraoperative laparoscopic ultrasound (IOLUS), a dynamic imaging technique, has emerged as a valuable instrument for guiding surgery in various medical specialties. As IOLUS provides accuracy, improved visualization, and real-time guidance, the integration of IOLUS into many surgical procedures has occurred and IOLUS assists surgeons during advanced procedures. Today, laparoscopic myomectomy has become a prominent surgical procedure in gynecology. Despite its benefits, laparoscopic myomectomy presents certain challenges. The risk of residual fibroids is higher in laparoscopic myomectomy compared to abdominal surgery. The limited depth perception and restricted range of motion can also be obstacles for surgeons, especially when dealing with deeply embedded fibroids. IOLUS has the potential to overcome these limitations. In this study, our aim was to conduct a review of the literature concerning the use of IOLUS during laparoscopic myomectomy.

Ultra-low-impact laparoscopy: a new concept for a minimally invasive surgery.

INTRODUCTION: Minimally invasive surgery is considered the gold standard for the treatment of gynecological diseases. Our study aims to assess the effectiveness of the new concept of ultra-low-impact laparoscopy as a combination of low-impact laparoscopy, consisting in the use of miniaturized instruments through 3-5mm ports and low-pressure pneumoperitoneum, with regional anesthesia to evaluate the perioperative outcomes. METHODS: A cross-sectional study was performed from May 2023 to December 2023, to enroll 26 women affected by benign gynecological disease and threated by mini-invasive surgical approach. The surgical procedures were performed following the low-impact laparoscopy protocol and the regional anesthesia protocol. The postoperative pain, nausea, and vomiting and the antiemetic/analgesic intake were evaluated. Postoperative surgical and anesthesiological variables were analyzed. RESULTS: Operative time was within 90 min (41.1 ± 17.1 mean ± standard deviation (SD)) and no conversion to laparotomy or general anesthesia was required. According to VAS score, the postoperative pain during the whole observation time was less than 3 (mean). Faster resumption of bowel motility (6.5 ± 2.1 mean ± SD) and women's mobilization (3.1 ± 0.7 mean ± SD) were observed as well as low incidence of post-operative nausea and vomit. Early discharge and patient's approval were recorded. Intraoperatively pain score was assessed on Likert scale during all stages. CONCLUSION: Ultra-low-impact laparoscopy showed to provide a satisfying recovery experience for patients in terms of short hospital stays, cosmetic result, and pain relief, without compromising surgical outcomes. The encouraging results lead us to recruit a greater number of patients to validate our technique as a future well-established produce.

Choledochal Cyst Diagnosed during Pregnancy and Treated by Postpartum Laparoscopic Choledochal Cyst Excision: Case Report.

We report a rare case of choledochal cyst with acute cholangitis that was diagnosed at 37 weeks' gestation and treated by laparoscopic choledochal resection and biliary reconstruction after delivery. A 31-year-old Japanese primigravida at 37 weeks' gestation presented with right upper quadrant pain. The patient was diagnosed as having acute cholangitis due to a type-Ia choledochal cyst, according to the Todani classification, with pancreaticobiliary maljunction. Acute cholangitis improved with conservative treatment, the fetus was delivered by Cesarean section at 38 weeks' gestation, and the patient was treated by laparoscopic choledochal cyst excision and biliary reconstruction at 47 days postpartum. Total operation time was 579 minutes and intraoperative body fluid loss was 100 mL. The patient is now healthy with normal liver function 7 years after the operation. To ensure good outcomes for the mother and fetus, treatment decisions for choledochal cyst diagnosed during pregnancy must be carefully considered.

Perioperative outcomes of robot-assisted versus laparoscopic distal gastrectomy for gastric cancer: a systematic review and meta-analysis of propensity score matching studies.

The aim of this meta-analysis was to compare the efficacy of robot distal gastrectomy (RDG) versus laparoscopic distal gastrectomy (LDG) for gastric cancer. Studies included only those that utilized propensity score matching (PSM). A systematic literature search was conducted in several major global databases, including PubMed, Embase, and Google Scholar, up to June 2024. Articles were screened based on predefined inclusion and exclusion criteria. Baseline data and primary and secondary outcome measures (e.g., operative time, estimated blood loss, lymph-node yield dissection, length of hospital stay, and time to first flatus) were extracted. The quality of PSM studies was assessed using the ROBINS-I, and data were analyzed using Review Manager 5.4.1 software. A total of 12 propensity score-matched studies involving 3688 patients were included in this meta-analysis. Robot-assisted surgery resulted in a longer operative time (WMD 30.64 min, 95% CI 15.63 - 45.66; p < 0.0001), less estimated blood loss (WMD 29.54 mL, 95% CI - 47.14 - 11.94; p = 0.001), more lymph-node yield (WMD 5.14, 95% CI 2.39 - 7.88; p = 0.0002), and a shorter hospital stay (WMD - 0.36, 95% CI - 0.60 - 0.12; p = 0.004) compared with laparoscopic surgery. There were no significant differences between the two surgical methods in terms of time to first flatus, overall complications, and major complications. Robot distal gastrectomy for gastric cancer reduces intraoperative blood loss, increases lymph-node yield, and shortens hospital stay compared with laparoscopic surgery, despite a longer operative time. There are no significant differences in time to first flatus and complication rates between the two groups.

Complementary pneumatic dilations are an effective and safe treatment when laparoscopic myotomy fails: A 30-year experience at a single tertiary center.

BACKGROUND: In the last 3 decades, laparoscopic Heller myotomy (LHM) has represented the treatment of choice for esophageal achalasia, solving symptoms in most patients. Little is known about the fate of patients relapsing after LHM or their treatment. In this study, we aimed at evaluating the results of complementary pneumatic dilations (CPDs) after ineffective LHM. METHODS: We evaluated the patients who underwent LHM with Dor fundoplication (LHD) from 1992 to 2022 and were submitted to CPD for persistent or recurrent symptoms. The patients were followed clinically and with manometry, barium swallow, and endoscopy when necessary. An Eckardt score (ES) of > 3 was used as threshold for failure. RESULTS: Of 1420 patients undergoing LHD, 120 (8.4%) were considered failures and were offered CPD. Ten patients refused further treatment; in 5 CPD was not indicated for severe esophagitis; 1 patient had surgery for a misshaped fundoplication and 1 patient developed cancer 2 years after LHD; that leaves 103 patients who underwent a median 2 CPDs (IQR, 1-3), at a median of 15 (IQR, 8-36) months after surgery, with 3.0- to 4.0-cm Rigiflex dilator (Boston Scientific, Massachusetts, USA). No perforations were recorded. Only 6 patients were lost to follow-up. Thus, 97 were followed for a median of 37 months (IQR, 6-112) after the last CPD: 70 (72%) were asymptomatic, whereas 27 (28%) had significant persistent dysphagia (ES > 3). The only differences between the 2 groups were the ES after surgery (P < .01) and the number of required CPD. Overall, the combination of LHD + CPD provided a satisfactory outcome in 96.5% of the patients. CONCLUSION: CPDs represent an effective and safe option to treat patients after a failed LHD: when the postsurgery ES consistently remains high and the number of CPDs required to control symptoms exceeds 2, this may suggest the need for further invasive treatments.

From Meshes to Minimally Invasive Techniques: A Comprehensive Review of Modern Hernia Repair Approaches.

Hernias are a common medical condition characterized by the protrusion of organs or tissues through weakened muscle walls, affecting millions worldwide annually. Historically, from being treated with open surgeries using tension-free mesh repairs, the landscape of hernia repair has evolved significantly.

This comprehensive review aims to elucidate the evolution of hernia repair techniques, emphasizing the transition from conventional mesh repairs to advanced minimally invasive methodologies. By examining the historical progression and current state of hernia surgery, this review thoroughly analyzes the advancements in surgical techniques, materials, and technologies. Furthermore, it explores emerging trends such as biological meshes, ultrasound-guided procedures, and 3D printing applications in hernia repair. The clinical significance of these advancements lies in their potential to enhance the patient's quality of life, minimize complications, and optimize healthcare resource utilization. Insights gained from this review will inform clinicians and researchers about the efficacy, safety, and comparative effectiveness of various hernia repair approaches, guiding future directions in hernia management and fostering innovation in surgical practice.

The Influence of Obesity on Cholecystectomy Outcomes: A Systematic Review of Laparoscopic and Open Approaches.

This systematic review evaluates the impact of obesity on the outcomes of laparoscopic versus open cholecystectomy, analyzing data from five key studies. The review explores differences in operative times, complication rates, conversion rates, and recovery times among obese patients undergoing these surgical procedures. The findings indicate that while laparoscopic cholecystectomy in obese patients tends to require longer operative times, it does not significantly increase complication rates compared to open cholecystectomy. However, the risk of conversion to open surgery is modestly elevated. The review highlights the necessity for surgical guidelines to adapt to the challenges posed by obesity, recommending advanced training and innovative technologies to improve surgical outcomes. Limitations such as study design heterogeneity and variability in defining obesity underscore the need for further research. This review contributes to optimizing surgical care strategies and improving patient outcomes in the growing demographic of obese surgical patients.

Initial Experience with Disposable Single-Use Cholangioscope During Laparoscopic Common Bile Duct Exploration.

Introduction: For patients with choledocholithiasis, laparoscopic common bile duct exploration (LCBDE) is more cost effective than endoscopic retrograde cholangiopancreatography (ERCP) and results in shorter hospital length of stay. As LCBDE can be technically challenging to perform, utilizing a disposable single-use cholangioscope (DSUC) for LCBDE through a cystic ductotomy has several advantages, such as potentially avoiding a choledochotomy and expanding access to cholangioscopes as a DSUC is disposable and does not require infrastructure for cleaning or maintenance. Methods: An IRB-approved, retrospective chart review from 2021 to 2023 was conducted for patients who underwent concurrent laparoscopic cholecystectomy (LC) and LCBDE with a DSUC (SpyGlass™ Discover, Boston Scientific, Natick, MA) for the management of choledocholithiasis diagnosed either preoperatively or during intraoperative cholangiogram (IOC). Primary endpoint was successful clearance of biliary duct stones. Results: Twelve patients with a mean age of 55.3 years (SD ±13.9) and mean body mass index of 33.8 (SD ±10.8) were found to have filling defects on IOC for LC and underwent LCBDE with DSUC. Of these, 10 patients had stones. Complete stone clearance was achieved in all 10 patients with various stone extraction maneuvers. The mean operative time was 189 minutes (SD ±63.6) and mean hospital length of stay postoperatively was 1 day (SD ±.8). Mean length of follow-up postoperatively was 26.9 (SD ±16.0) days. There were no intraoperative complications, no need for repeat procedures, and only one postoperative complication involving a superficial surgical site infection requiring oral antibiotics. Conclusions: LCBDE with a DSUC is safe and efficacious for clearing stones and identifying pathology of the CBD. Familiarity with this device is especially useful for surgeons who want to simultaneously manage choledocholithiasis at the same time as cholecystectomy to reduce hospital stay and overall cost.

The short-term efficacy of neoadjuvant SOX versus SOX plus immune checkpoint inhibitor following laparoscopic gastrectomy for locally advanced gastric cancer: a multicenter retrospective cohort study in China.

BACKGROUND: This study aims to evaluate the short-term efficacy for locally advanced gastric cancer (LAGC) who accepted laparoscopic gastrectomy (LG) after neoadjuvant SOX versus SOX plus immune checkpoint inhibitors (ICIs). METHODS: LAGC patients who accepted LG after neoadjuvant SOX (SOX-LG, n = 169) and SOX plus ICIs (SOX + ICIs-LG, n = 140) in three medical centers between Jan 2020 and Mar 2024 were analyzed. We compared the tumor regression, treatment-related adverse events (TRAEs), perioperative safety between two groups, and explored the risk factors of postoperative complications (POCs) for LG after neoadjuvant therapy. RESULTS: The baseline characteristics were comparable between two groups (P > 0.05). SOX + ICIs-LG group acquired a higher proportion of objective response (63.6% vs. 46.7%, P = 0.003), major pathological response (43.6% vs. 31.4%, P = 0.001), and pathological complete response (17.9% vs. 9.5%, P = 0.030). There were no significant differences in the TRAEs rates, operation time, R0 resection, retrieved lymph nodes, postoperative first flatus, and hospitalized days, overall and severe POCs between two groups (P > 0.05). Patients in the SOX-ICIs-LG group had lower estimated blood loss (EBL) compared with SOX-LG (P = 0.001). Multivariate analysis showed that more EBL (P = 0.003) and prognostic nutritional index (PNI) < 40 (P = 0.005) were independent risk factors of POCs for LG after neoadjuvant therapy. CONCLUSION: Neoadjuvant SOX plus ICIs brings better tumor regression and similar TRAEs compared with SOX alone for LAGC. SOX + ICIs-LG is safe and feasible to conduct with less EBL. Surgeons should focus on the perioperative management to control POCs for patients with PNI < 40 and more EBL.
