Study objective: To determine if a pre-operative morphine/bupivacaine spinal injection prior to laparoscopic hysterectomy reduced postoperative pain and resulted in less opioid consumption during the hospital stay.

Methods: A retrospective cohort study (Canadian Task Force Classification II-2) was conducted at a single institution regional referral center (community hospital) in North Carolina. Three hundred nineteen patients met criteria for inclusion: 192 received spinal anesthesia and 127 did not. Baseline demographics were similar between the two groups. Median pain scores were significantly lower in the treatment than the control group on day of surgery (DOS) (2 vs. 6; P < 0.001) and postoperative day 1 (POD1) (2 vs. 4; P < 0.001).

Results: Primary outcomes were pain scores on DOS and POD1 and inpatient opioid use. Pain scores were obtained using the 0 to 10 Numerical Rating Scale. Opioids were converted to oral morphine milliequivalents (OME). Median opioid use was also significantly lower in the treatment than the control group on DOS (0 vs. 15.00 OME; P < 0.001) and POD1 (0 vs. 7.5 OME; P < 0.001). Median length of stay between the groups was not significantly different.

Conclusion: Pre-operative morphine spinal injection for laparoscopic hysterectomy led to significantly lower pain scores and inpatient opioid consumption. Pre-operative spinal anesthesia for benign laparoscopic hysterectomy appears helpful for enhancing the postoperative experience.

Background and objectives: To demonstrate the feasibility and potential of robotic single-site cholecystectomy, the study aimed to compare it with conventional laparoscopic cholecystectomy.

Methods: In total, 791 consecutive patients underwent conventional laparoscopic cholecystectomy or robotic single-site cholecystectomy at our center between 2019 and 2022. After 1:1 propensity score matching, 117 patients for each group were selected.

Results: After propensity score matching, the only statistically significant difference between conventional laparoscopic cholecystectomy and robotic single-site cholecystectomy was operative time, which was 29.15 ±11.45 min in the conventional laparoscopic cholecystectomy group versus 38.57 ± 12.59 min in the robotic single-site cholecystectomy group (P < 0.001). Because the difference in surgical time between the two groups was minimal, it has little clinical relevance. Using cumulative sum analysis, the maturation phase of the total operation and docking times occurred after the 53rd case. To reduce bias, a comparison of results with conventional laparoscopic cholecystectomy and cases of robotic single-site cholecystectomy was performed in the maturation phase, which revealed only total operative time as statistically significant (P < 0.001).

Conclusion: Robotic single-site cholecystectomy is a technically feasible and safe method for treating benign gallbladder diseases, with a relatively short learning curve and reasonable operative time.

Background: As the population continues to age, the number of elderly patients affected by obesity is rising. Metabolic and bariatric surgery (MBS) can benefit elderly patients seeking treatment for obesity and its related diseases. We aimed to quantify percent excess weight loss (%EWL) for elderly patients (≥ 65) undergoing MBS at a single institution and compare our results to %EWL previously reported for general and elderly populations. Additionally, we believe the safety and effectiveness of MBS is repeatable in our community setting.

Methods: Laparoscopic sleeve gastrectomy and laparoscopic roux-en-Y gastric bypass performed from November 1, 2011 - April 30, 2017 at a single institution was retrospectively reviewed. Weight loss was measured at 3, 6, and 12 month follow-up. A total of 103 patients met inclusion criteria, mean age was 67.75 years old and mean pre-operative body mass index was 45.95 kg/m².

Results: Mean %EWL was 31.9%, 43.7%, and 53.4% at 3, 6, and 12 months, respectively. %EWL at one year was not statistically different to prior reports of elderly bariatric patients (p = 0.979). While statistically lower when compared to reports in the general population, %EWL in our elderly patients was clinically similar (p < 0.001). No 30-day mortality was observed.

Conclusions: Elderly patients undergoing MBS were noted to have %EWL similar to previous reports in elderly and general populations. MBS is efficacious and well tolerated in the elderly population with repeatable results. Continued reporting on the safety and efficacy is important in ensuring wider coverage and availability of these important interventions in elderly populations.

Objective: Determine the difference in microbial growth from the vagina and uterine manipulator among patients undergoing laparoscopic hysterectomy after randomization to one of three vaginal preparation solutions (10% Povidone-iodine, 2% Chlorhexidine, or 4% Chlorhexidine).

Method: This was a prospective randomized controlled trial in an academic community hospital. Patients were ≥ 18 years old and scheduled for laparoscopic hysterectomy for benign and malignant indications.

Results: Fifty patients were identified and randomized into each arm. Prior to surgery, the surgical team prepared the vaginal field using 10% Povidone-iodine, 2% Chlorhexidine, or 4% Chlorhexidine, according to group assignment. Cultures were collected from the vagina after initial preparation, prior to the colpotomy, and on surfaces of the uterine manipulator. Bacterial count from the baseline vaginal fornix/cervical canal cultures did not differ significantly among the three groups. There was a difference in bacterial count among the second cervical canal/vaginal fornix cultures (p < 0.01), with the Povidone-iodine arm demonstrating the highest level of growth of cultures (93.8%), followed by 2% Chlorhexidine (47.4%), and 4% Chlorhexidine (20%). There was no difference in growth on the uterine manipulator handle and no difference in vaginal itching or burning was found across the three arms postoperatively.

Conclusion: Bacterial growth prior to colpotomy was the lowest with 4% Chlorhexidine followed by 2% Chlorhexidine, the Povidone-iodine group exhibited the highest bacterial growth. There was no difference in moderate to severe vaginal itching or burning. This showed that 4% Chlorhexidine is superior in reducing bacterial growth when used in laparoscopic hysterectomy.

Background and objectives: Most thermal energy-induced distal ureter injuries are missed intraoperatively as they are caused by delayed ischemia-induced necrosis of the affected part leading to fistula, and a delayed presentation. The injuries of the distal ureter are commonly managed by ureteroneocystostomy, which has long-term complications related to vesico-ureteric reflux (VUR). We present our experience of management of distal ureter injury due to thermal energy by laparoscopy ureteroureterostomy and the role of various methodologies for its diagnosis.

Methods: It is a retrospective, single-center study that was conducted from January 1, 2020 - December, 31 2022.

Results: A total of 8 cases were enrolled in the study. All cases had an uterovaginal fistula (UVF) post-laparoscopic gynecology surgery. The bilateral ureteric injury was observed in 2 cases. The median post-surgery time to diagnose UVF in the study was 10 days. All cases were managed by laparoscopy ureteroureterostomy (LUUS). Six cases underwent immediate surgery after the diagnosis; whereas 2 cases had initial double-J stent placement as treatment, which subsequently failed following which the LUUS was performed. There were not any immediate or long-term complications such as leakage, stenosis, fistula, or any requirement for revision surgery.

Conclusion: The management of thermal energy-induced ureteric injury is exceptional as compared to other types of ureteric injury. Our approach should be toward immediate surgical management rather than a conservative one to avoid long-term complications and sequelae. Iatrogenic lower ureteral injury can be managed successfully by LUUS, maintaining the normal anatomy and physiology of VUR.

Background and objectives: Robotic surgical technology may obviate the need for an assistant surgeon when performing hysterectomy. In rural communities where physician shortages remain a major barrier to healthcare access, reducing the number of surgeons necessary to complete a hysterectomy would be of significant consequence. We sought to investigate the impact of robotic surgery on both the presence of an assistant surgeon and route of hysterectomy following implementation of a robotic surgery program at a single-site community hospital.

Methods: Retrospective chart review of hysterectomies performed before and after implementation of a robotic surgical program. Hysterectomies were classified by presence of an assistant surgeon, and by mode of hysterectomy (abdominal, laparoscopic, robotic, and vaginal). We observed the distribution of outcomes between the two study periods and compared them with the χ² test.

Results: Following implementation of a robotic surgical program we observed a statistically significant decrease in the presence of an assistant surgeon at the time of hysterectomy from 86.7% to 29.7%, p ≤ 0.0001. There was also an increase in the percentage of hysterectomies performed by minimally invasive technique from 67.0% to 87.4%, p ≤ 0.0001.

Conclusion: Following implementation of a robotic gynecologic surgery program at a single-site rural community hospital, we observed a reduction in the utilization of an assistant surgeon at time of hysterectomy. Additionally, we observed a significant increase in the rate of minimally invasive hysterectomies performed.

Background and objectives: This is a prospective trial of the endo-stapler application for vaginal closure before colpotomy in cases of carcinoma endometrium and carcinoma cervix, managed by minimally invasive surgery with due consideration of its surgical technique and short-term oncologic follow-up outcomes.

Methods: This was a prospective, single center study completed between March 1, 2020 and December 31, 2022. A total of 62 patients (43 cases of carcinoma endometrium and 19 cases of carcinoma cervix) were recruited for the study. Oncologic survival outcomes at the end of 1 and 2 years were documented.

Results: There were no major intraoperative bowel, urinary, or vascular injuries. None of the cases required conversion to laparotomy peroperatively. Our study had 8 patients with carcinoma endometrium (8/43) and 7 patients of carcinoma cervix (7/19) who have completed 24 months of follow-up without any recurrence to date.

Conclusion: Endo-stapler application for enclosed colpotomy to prevent tumor spillage is a futuristic step in gynecologic oncology cases managed by laparoscopy.

Background: The surgical procedure One Anastomosis Gastric Bypass (OAGB) has become widely used worldwide. Since its inception, many modifications have been introduced to improve results.

Objectives: The primary aim of this study was to share the modifications that we have introduced to our OAGB technique after reflecting on the problems and complications we have faced during the evolution of this procedure in our unit.

Method: A total of 850 patients who underwent OAGB under the same surgical team at two different hospitals in the United Kingdom were displayed according to demography and comorbidities. All complications were reviewed and analysed to instigate the changes in our technique.

Results: There were 756 (89%) primary and 94 (11%) revisional procedures. There were 596 females (70.11%) and 254 males (29.89%) in our study group. The body mass index range was 32-84 and the mean was 45. The pre-operative weight range was 89-274 kg and the mean was 126.4 kg.

Conclusions: With experience and reflecting on our complications we have modified our surgical approach, and these alterations have helped us to adopt OAGB as the mainstream bariatric procedure. We want to share our experience with the bariatric community for the benefit of patient care.

Background and objectives: The objectives of this study were to determine carbon dioxide (CO₂) emissions generated from nonreusable waste and compare across different types of hysterectomies for benign and malignant indications. Overall greenhouse gas emissions were not examined.

Methods: This is a prospective cohort study that identified women undergoing a robotic assisted, laparoscopic, vaginal, or abdominal hysterectomy for any indication. The amount of waste generated was collected for each case, along with patient demographics, and details of the procedure. Weight of waste was converted to kilograms of CO₂ emissions using the following formula: $\text{Carbon\hspace{0.17em}dioxide\hspace{0.17em}emissions}\hspace{0.17em}=\hspace{0.17em}\text{Waste\hspace{0.17em}in\hspace{0.17em}pounds }\mathrm{\times \hspace{0.17em}1\hspace{0.17em}Short\hspace{0.17em}ton}/2000\text{\hspace{0.17em}pounds }\mathrm{\times Emission\hspace{0.17em}factor\hspace{0.17em}}\left(\text{kg\hspace{0.17em}C}{\text{O}}_2/\text{short\hspace{0.17em}ton}\right)\text{× Global\hspace{0.17em}\hspace{0.17em}warming potential\hspace{0.17em}(GWP)}$We extrapolated the amount of CO₂ emissions produced to the number of hysterectomies performed annually in the United States.

Results: We found that robotic hysterectomies generated the highest mean CO₂ emissions (12.01 kg CO₂), while vaginal hysterectomies produced the lowest mean CO₂ emissions of 4.48 kg (p < .0001).Our sample size of 100 hysterectomies was equivalent to 1099.4 kg CO₂ emissions. When our results were extrapolated, all hysterectomies in the United States produce 5.7 million kg of CO₂ emissions. This is equivalent to 234,513 airplane miles, and 95 trips cross-country across the USA from New York, New York to Los Angeles, California.

Conclusion: Robotic hysterectomies generated a statistically significant majority of CO₂ emissions. Therefore, robotic surgery, as currently practiced, may offer a good initial opportunity for decreasing the carbon footprint of surgery.

Background and objectives: In order to avoid potential complications from incisional hernias in patients undergoing laparoscopic or robotic procedures with 10 mm or larger ports, a surgeon closes the fascial defects using various techniques. We compared several different techniques of port site closure, which uses the open technique that can be performed with or without laparoscopic visualization. We modified the technique initially described by Dr. H. Aziz. We are introducing a new surgical technique to close the larger port site using Graham's nerve-hook. This new technique is easy to learn, replicate and implement for all body types.

Methods: We use the commonly available Graham's nerve-hook and two S-retractors to visualize the entire layers of fascia and peritoneum and to pull up both layers to close the larger port site safely and securely with 0 polyglactin absorbable suture. We illustrated this new Lee's port site closure technique with eight separate drawings in this paper.

Results: We performed 493 consecutive laparoscopic cases using this new technique. Four years follow up revealed only one incisional hernia using this technique. The patients are routinely followed in one month and six months and a year after the operation. However, not all of the patients are seen after six months unless there was a specific complaint.

Conclusion: The new port site closure technique introduced in this paper is found to be easy to learn, fast, and very cost effective due to the reusable, commonly found S-retractors and Graham's nerve hook. After four years of consistent use, this new technique was found to be safe and effective in closure of 10 mm or larger port sites.
