Background: Appendectomy for acute appendicitis is the most common acute abdominal surgery. Open and laparoscopic appendectomy surgeries are performed with different techniques. Laparoscopic appendectomy has become a widespread method due to its advantages. The aim of this study is to compare the complications, surgery time, hospitalization length, and cost-effectiveness of titanium clips and hem-o-lok clips for stump closure in laparoscopic appendectomy.

Methods: This study included 187 patients who were operated on laparoscopically for acute appendicitis at our hospital between April 2019 and June 2022. The patients' follow-up for 30 days after surgery was evaluated. The data of 179 patients in whom titanium and hem-o-lok clips were inserted during an appendectomy were included in the study.

Results: Between April 2019 and June 2022, 179 patients were included in the study retrospectively. When the correlation between complications and surgical methods was analyzed, 98.8% of the hem-o-lok clip group and 99% of the titanium clip group had no complications. No statistically significant difference was observed between complications and surgery type (P > .05). In the hem-o-lok and titanium clip groups, the operative time was 52.4 minutes and 53.1 minutes, and the hospitalization times were 1.7 days and 1.8 days, respectively.

Conclusions: It is concluded that the use of titanium clips that completely close the root of the appendix is as safe, accessible, feasible, practical, and effective as the hem-o-lok clip method. It was observed to be used safely as an alternative to other appendix root closure methods.

Background and objectives: Racial and ethnic disparities in access to minimally invasive surgery (MIS) and the rate of surgical complications in minority groups remain profoundly underinvestigated. This meta-analysis aims to compare the rate of MIS utilization for benign hysterectomy as well as the surgical morbidity among racial and ethnic minority patients in the United States.

Methods: Studies comparing utilization rate of MIS for benign hysterectomy among non-Hispanic white, Black, and Hispanic populations were considered eligible. The primary outcome was the rate of MIS according to race. The secondary outcome was surgical morbidity risk (Clavien-Dindo Classification) according to hysterectomy route and race. Random-effect model meta-analysis pooled unadjusted and adjusted odds ratios (ORs) with 95% confidence intervals (CIs).

Results: Thirteen studies were eligible, with a total of 1,123,851 patients undergoing benign hysterectomy, of whom 817,209 were white, 187,488 Black, and 119,154 Hispanic. Black and Hispanic patients were less likely to undergo MIS compared to white patients (Black: OR 0.44 [95% CI 0.39-0.49] and Hispanic: OR 0.65 [95% CI 0.59-0.71]). After pooling adjusted estimates, the rate of MIS use remained significantly lower in nonwhite populations. Nonwhite patients were more likely to develop surgical complications after hysterectomy in either MIS (OR 1.32 [95% CI: 1.15-1.52]) or open hysterectomy (OR 1.56 [95% CI: 1.40-1.73]).

Conclusion: Racial and ethnic disparities in MIS utilization for benign hysterectomy are strikingly apparent in the United States, with nonwhite patients often demonstrating lower access to MIS utilization and higher rates of surgical morbidity than white patients.

Background and objective: Robotic cholecystectomy has technical advantages of 3D visualization, enhanced instrument maneuverability, and increased precision. Less chance of conversion to open and biliary spillage. This study explores the utilization of the BORNS Simphoni Robotic System for robotic cholecystectomy.

Methods: The paper discusses the safety and efficacy of the system during a phase 1 clinical trial, focusing on key technical steps, outcomes, and comparisons with conventional laparoscopic cholecystectomy.

Results: Results from the trial indicate successful completion of surgeries with no conversions to open procedures, minimal blood loss, and low postoperative pain.

Discussion: The BORNS Simphoni system offers advanced features such as an open console design, articulating and nonarticulating instruments, and integrated ultrasonic energy sources. The study suggests the feasibility and effectiveness of robotic cholecystectomy using the BORNS Simphoni system. However, a larger sample size is needed to further evaluate and confirm these findings, as well as to assess the cost-effectiveness of this platform for broader adoption.

Background and objectives: Securing the base of the appendix is the most critical part of laparoscopic appendectomy in children. Determining the average values of the appendix, will facilitate the creation of suitable instruments, and will also have an impact on research in imaging studies.

Methods: One hundred and eight patients with the acute appendicitis were randomized into 2 groups: group I: children aged 2-10 years old, group II: children >10 years of age. Each group was further divided into 3 subgroups: phlegmonous, gangrenous and perforated forms of acute appendicitis. The external diameter of the appendiceal base, the middle part of the appendix, the tip and the length were determined. The measurements were made with the help of Vernier calipers, and expressed in millimeters.

Results: In group I, the average size of the appendiceal base in the phlegmonous form was 5.68 ± 1.51 mm, in the gangrenous form 7.08 ± 1.82 mm, and in the perforated form 6.94 ± 2.43 mm. In group II, the average size of the appendiceal base in the phlegmonous form was 7.29 ± 2.75 mm, in the gangrenous form 7.24 ± 2.11 mm, and in the perforated form 9.31 ± 3.07 mm.

Conclusion: Although most appendices can be removed by standard methods, the maximum sizes observed in this study reveal that standard endoloop or plastic and titanium clips cannot be used in the procedure and instead the more expensive stapler has to be utilized.

Despite evidence indicating patient and hospital benefits of minimally invasive surgery (MIS) over open surgery, there is still access barriers to MIS. Availability of training and associated learning curve, health literacy, and hospital characteristics (location, size) have been identified as the primary barriers to the adoption of MIS. Robotic assisted surgery could help to overcome some of these barriers and increase access to MIS through easier tele-mentoring and potential for remote access.

Background: Chronic pelvic pain remains challenging for physicians to manage due to central and peripheral sensitization and multiple pain generators including the bladder, pelvic floor, and pudendal nerve. Pain management providers have used nerve blocks for years for diagnosis and treatment. We developed a desensitization algorithm that provides a stepwise approach to improve patients pain scores.

Methods: This is a prospective observational cohort study of 182 women aged 15-90 years old with chronic pelvic pain using an algorithm from 2016 to 2018. Treatment started with an Anesthetic Challenge Test of the bladder to guide us through a protocol of intravesical therapy and/or pudendal nerve blocks as a second step.

Results: ACT POSITIVE patients, who received intravesical therapy: 84% had a Visual Analog Score pain improvement of at least 50%, 64% improved at least 80% (41% pain-free). Those desiring additional relief that received further Pudendal Blocks: 83% had final improvement of at least 50% (67% pain-free). ACT NEGATIVE patients received Pudendal Blocks with 80% of subjects achieving at least 50% relief, 65% improved at least 80% (35% pain-free). All final groups showed a statistically significance of P < .05% when compared to their initial pain scores.

Conclusion: Management of women with chronic pelvic pain would ideally start with treating a specific diagnosis which, in most cases, is difficult to establish since the majority have more than one pain generator. Our algorithm simplified the approach and reduced the severity of pain scores prior to any further necessary surgical interventions.

Background: Anorectal diseases and pelvic floor disorders are prevalent among the general population. Patients may present with overlapping symptoms, delaying diagnosis, and lowering quality of life. Treating physicians encounter numerous challenges attributed to the complex nature of pelvic anatomy, limitations of diagnostic techniques, and lack of available resources. This article is an overview of the current state of artificial intelligence (AI) in tackling the difficulties of managing benign anorectal disorders and pelvic floor disorders.

Methods: A systematic literature review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched the PubMed database to identify all potentially relevant studies published from January 2000 to August 2023. Search queries were built using the following terms: AI, machine learning, deep learning, benign anorectal disease, pelvic floor disorder, fecal incontinence, obstructive defecation, anal fistula, rectal prolapse, and anorectal manometry. Malignant anorectal articles and abstracts were excluded. Data from selected articles were analyzed.

Results: 139 articles were found, 15 of which met our inclusion and exclusion criteria. The most common AI module was convolutional neural network. researchers were able to develop AI modules to optimize imaging studies for pelvis, fistula, and abscess anatomy, facilitated anorectal manometry interpretation, and improved high-definition anoscope use. None of the modules were validated in an external cohort.

Conclusion: There is potential for AI to enhance the management of pelvic floor and benign anorectal diseases. Ongoing research necessitates the use of multidisciplinary approaches and collaboration between physicians and AI programmers to tackle pressing challenges.

Background and objectives: Haemostasis-related complications associated with Medtronic Tri-staple^TM with preloaded buttress material and the novel, naked AEON^TM gastrointestinal staplers have not been extensively studied in bariatric surgery. The study aimed to assess and compare the 30-day haemostasis-related complications between Medtronic Tri-staple^TM and AEON^TM GIA staplers.

Methods: A retrospective analysis was performed on data from patients who underwent primary or revision sleeve gastrectomy (SG) or the sleeve component of single anastomosis duodeno-ileal bypass with SG (SADI-S) in a private hospital in Australia between November 2021 and December 2022. The surgeries were performed by a single surgeon, using either Medtronic Tri-staple^TM or AEON^TM staplers.

Results: The analysis included 250 patients, with the first 125 consecutive patients receiving staple line using the Medtronic Tri-staple^TM GIA stapler and the subsequent 125 patients receiving staple line using the AEON^TM GIA stapler. Statistical analysis revealed no significant differences in the distribution of surgical procedures between the Medtronic and AEON groups. In the AEON group, there were statistically higher numbers of diabetics and former tobacco users, while other preoperative characteristics did not significantly differ between the two groups. The AEON group had a significantly longer mean operative time, while the length of hospital stay was significantly shorter. No intraoperative or 30-day complications, deaths, emergency room visits, readmissions, or reoperations were observed in either group.

Conclusion: The novel, naked AEON^TM stapler demonstrated non-inferiority to the established Medtronic Tri-Staple^TM with preloaded buttress material in achieving hemostasis and maintaining staple-line integrity in bariatric surgery.

Background: As the number of limitations increases in a medical research article, their consequences multiply and the validity of findings decreases. How often do limitations occur in a medical article? What are the implications of limitation interaction? How often are the conclusions hedged in their explanation?

Objective: To identify the number, type, and frequency of limitations and words used to describe conclusion(s) in medical research articles.

Methods: Search, analysis, and evaluation of open access research articles from 2021 and 2022 from the Journal of the Society of Laparoscopic and Robotic Surgery and 2022 Surgical Endoscopy for type(s) of limitation(s) admitted to by author(s) and the number of times they occurred. Limitations not admitted to were found, obvious, and not claimed. An automated text analysis was performed for hedging words in conclusion statements. A limitation index score is proposed to gauge the validity of statements and conclusions as the number of limitations increases.

Results: A total of 298 articles were reviewed and analyzed, finding 1,764 limitations. Four articles had no limitations. The average was between 3.7% and 6.9% per article. Hedging, weasel words and words of estimative probability description was found in 95.6% of the conclusions.

Conclusions: Limitations and their number matter. The greater the number of limitations and ramifications of their effects, the more outcomes and conclusions are affected. Wording ambiguity using hedging or weasel words shows that limitations affect the uncertainty of claims. The limitation index scoring method shows the diminished validity of finding(s) and conclusion(s).

Objectives: We present our initial clinical experience applying Natural Orifice Transluminal Endoscopic Surgical (NOTES) technique to perform cholecystectomy in ten patients at a military institution.

Methods: A posterior colpotomy was created to accommodate a single site working port used to facilitate dissection and gallbladder mobilization under direct visualization via an infraumbilical port. The specimen was retrieved through the vagina and the colpotomy was closed with absorbable suture under direct visualization. Long-term follow up was performed over the phone to assess quality of life with 2 widely used health-related quality of life (HRQoL) surveys including RAND-36 Health Item Survey (Version 1.0),¹ and the Female Sexual Function Index (FSFI).².

Results: Ten women underwent a laparoscopic-assisted transvaginal cholecystectomy (TVC) with 7 available for long-term follow-up. The average age was 28.9 years (20-37) and the indications for surgery included symptomatic cholelithiasis (9) and biliary dyskinesia (1). The mean operative time was 129 mins (95-180), and median blood loss was 34 ml (5-400). There were no conversions and the average length of stay was 9.98 hours (2.4-28.8). Pain (analogue scale 1-10) on postoperative day three was minimal (mean 2.3) and was limited to the infraumbilical incision. On average patients returned to work by postoperative day six and resumed normal daily activities at seven days. Immediate postoperative complications included one incident of postoperative urinary retention requiring bladder catheterization. One intra-operative cholangiogram was successfully performed due to elevated preoperative liver enzymes without significant findings. Long-term complications included one asymptomatic incisional hernia repair at the infraumbilical port site. The RAND-36 survey demonstrated an average physical and mental health summary score of 82.2 and 63.7 with an average general health score of 63.6. The average FSFI total score was 21.8.

Conclusion: TVC is safe and effective. Implementation may improve operational readiness by returning service members to normal activities more expeditiously than conventional laparoscopy.
