Introduction: Our study's objective was to provide the method for, and preliminary findings from, robot-assisted cytoreductive surgery (r-CRS) combined with upper-abdominal peritonectomy in pseudomyxoma peritonei (PMP) with limited peritoneal surface malignancy (PSM).

Materials and methods: We conducted a retrospective pilot study on consecutive patients with PSM secondary to pseudomyxoma peritonei with a peritoneal cancer index (PCI) of under 10 who were indicated for r-CRS combined with upper-abdominal peritectomy. Perioperative and 30-day major morbidity and mortality characteristics were analyzed and compared with cases in which laparoscopic CRS (l-CRS) was performed under the same conditions.

Results: Six patients underwent r-CRS combined with an upper-abdominal partial peritonectomy. Their mean PCI was 4.83. Complete cytoreduction was achieved in all patients. The mean duration of the operation was 156.8 minutes. There was no major complication and no mortality. The mean length of hospital stay after surgery was 6.33 days. r-CRS resulted in less blood loss, a lower C-reactive protein level, and a shorter length of hospital stay that were significantly different compared with those of l-CRS.

Conclusions: This is the initial technical report of a robotic approach for CRS combined with upper-abdominal peritonectomy. r-CRS with a combined upper-abdominal peritonectomy was shown to be safe and feasible for PMP with limited PSM.

Objective: The antireflux surgical technique with the RefluxStop device is one of the latest approaches to treating patients with gastroesophageal reflux disease (GERD). The aim of this study was to assess the safety and feasibility of laparoscopic hiatal hernia (HH) repair with the RefluxStop device in patients with GERD and concurrent large HH (≥4 cm).

Patients and methods: A retrospective chart review was performed for the first 30 patients with a large HH who consented and underwent HH surgery with the RefluxStop device. The operative technique and outcomes were evaluated to assess safety and feasibility, HH recurrence, dysphagia, and patient satisfaction.

Results: Between May 2020 and April 2022, 30 patients underwent laparoscopic HH repair with the RefluxStop device. All patients had typical symptoms of GERD, such as heartburn and regurgitation, and 15 patients (50%) had preoperative dysphagia. Median HH size was 5 cm (interquartile range, 4 to 5). Median operating time was 56 minutes (interquartile range, 52 to 63), with no intra and postoperative complications related to the device. One patient required laparotomy due to adhesions and associated bleeding when accessing the abdomen. All patients had postoperative imaging (video fluoroscopy) on postoperative day 1 and at 3 months, confirming the correct location of the RefluxStop device. One patient (3.3%) needed postoperative balloon dilatation due to severe dysphagia. Reflux symptoms (heartburn and acid regurgitation) resolved significantly in all patients ( P < 0.001) at 6 months. One episode of recurrence of HH (3.3%) occurred during the follow-up period of 6 months.

Conclusion: This study demonstrates the short-term safety and feasibility of laparoscopic HH repair with the RefluxStop device in patients with large HH, with a low rate of postoperative dysphagia and subsequent improvement or resolution of reflux symptoms in all patients.

Background: Foreign bodies within the pleura and pancreas are infrequent, and the approaches to their treatment still a subject of debate. There is limited knowledge particularly regarding glass foreign bodies.

Methods: We present a case involving large glass splinters in the pleura and pancreas, with an unknown entry point. In addition, a systematic review was conducted to explore entry hypotheses and management options.

Results: In addition to our case, our review uncovered eight incidents of intrapleural glass, and another eight cases of glass in other intrathoracic areas. The fragments entered the body through impalement (81%), migrated through the diaphragm after impalement (6%), or caused transesophageal perforation (19%) following ingestion. Eight instances of glass inside the abdominal cavity were documented, with seven resulting from impalement injuries and one from transintestinal migration. There were no recorded instances of glass being discovered within the pancreas. Among the 41 nonglass intrapancreatic foreign bodies found, sewing needles (34%) and fish bones (46%) were the most common; following ingestion, they had migrated through either a transgastric or transduodenal perforation. In all these cases, how the foreign bodies were introduced was often poorly recalled by the patient. Many nonglass foreign bodies tend to become encapsulated by fibrous tissue, rendering them inert, though this is less common with glass. Glass has been reported to migrate through various tissues and cavities, sometimes with a significant delay spanning even decades. There are cases of intrapleural migration of glass causing hemothorax, pneumothorax, and heart and major blood vessels injury. For intrapleural glass fragment management, thoracoscopy proved to be effective in 5 reported cases, in addition to our patient. Most intrapancreatic nonglass foreign bodies tend to trigger pancreatitis and abscess formation, necessitating management ranging from laparoscopic procedures to subtotal pancreatectomy. There have been only four documented cases of intrapancreatic needles that remained asymptomatic with conservative management. There is no direct guidance from the existing literature regarding management of intrapancreatic glass foreign bodies. Consequently, our patient is under observation with regular follow-ups and has remained asymptomatic for the past 2 years.

Conclusions: Glass foreign bodies in the pleura are rare, and our report of an intrapancreatic glass fragment is the first of its kind. Impalement is the most likely method of introduction. As glass has significant migration and an ensuing complication potential, preventive removal of intrapleural loose glass should be considered. However, intrapancreatic glass fragment management remains uncertain.

Objective: In this study, we aimed to evaluate the efficacy of the Magnetic Scope Guide Assist (ScopeGuide) in enhancing the procedural competence of endoscopists and reducing patient discomfort during colonoscopy.

Methods: This was a retrospective study with 88 trainee participants. The study participants were trained on patients who underwent colonoscopy without anesthesia. Both ScopeGuide-assisted training and conventional training (without ScopeGuide) were utilized for colonoscopy instruction. The outcomes of training were compared, with a particular emphasis on the competency of looping resolution.

Results: ScopeGuide-assisted training was superior to conventional training in multiple aspects, including looping resolution ( Z =-3.681, P <0.001), pain scores ( Z =-4.211, P <0.001), time to reach the cecum ( Z =-4.06, P <0.001), willingness to undergo repeat colonoscopy ( Z =-4.748, P <0.001), competence of positional changes ( Z =-4.079, P <0.001), and the effectiveness of assisted compression ( Z =-3.001, P =0.003). Further stratified analysis revealed that the ScopeGuide-assisted training mode was more beneficial for junior endoscopists ( P <0.05 in all parameters) but not for intermediate endoscopists ( P >0.05) and partially beneficial for senior endoscopists ( P <0.05 for all parameters except looping resolution).

Conclusion: ScopeGuide-assisted training can significantly facilitate endoscopists in resolving loops and reducing patient pain, thereby enhancing their colonoscopy abilities.

Background: The ongoing opioid crisis demands an investigation into the factors driving postoperative opioid use. Ambulatory robotic colectomies are an emerging concept in colorectal surgery, but concerns persist surrounding adequate pain control for these patients who are discharged very early. We sought to identify key factors affecting recovery room opioid use (ROU) and additional outpatient opioid prescriptions (AOP) after ambulatory robotic colectomies.

Methods: This was a single-institution retrospective review of ambulatory robotic colon resections performed between 2019 and 2022. Patients were included if they discharged on the same day (SDD) or postoperative day 1 (POD1). Outcomes of interest included ROU [measured in parenteral morphine milligram equivalents (MMEs)], AOP (written between PODs 2 to 7), postoperative emergency department presentations, and readmissions.

Results: Two hundred nineteen cases were examined, 48 of which underwent SDD. The mean ROU was 29.4 MME, and 8.7% of patients required AOP. Between SDD and POD1 patients, there were no differences in postoperative emergency department presentations, readmissions, recovery opioid use, or additional outpatient opioid scripts. Older age was associated with a lower ROU (-0.54 MME for each additional year). Older age, a higher body mass index, and right-sided colectomies were also more likely to use zero ROU. Readmissions were strongly associated with lower ROU. Among SDD patients, lower ROU was also associated with higher rates of AOP.

Conclusion: Ambulatory robotic colectomies and SDD can be performed with low opioid use and readmission rates. Notably, we found an association between low ROU and more readmission, and, in some cases, higher AOP. This suggests that adequate pain control during the postoperative recovery phase is a crucial component of reducing these negative outcomes.

Objective: Dexmedetomidine (DEX) can strengthen the analgesic effects of local anesthetics (LAs) when used as an adjuvant through intrathecal, perineural, and intraperitoneal routes. Many studies have used intraperitoneal instillation of DEX with LAs in laparoscopic cholecystectomy (LC) to relieve postoperative pain. We performed a systematic review and meta-analysis to synthesize evidence of the efficacy and safety of intraperitoneal instillation of DEX as an adjuvant of LAs in patients undergoing LC.

Methods: A comprehensive literature search of the MEDLINE, PubMed, EMBASE, and Cochrane Library databases was performed to identify randomized controlled trials in which patients received intraperitoneal instillation of DEX combined with LAs during LC. A meta-analysis and sensitivity analysis of the results were conducted. We also performed a subgroup analysis to investigate the source of heterogeneity. The Egger test was used to check for publication bias.

Results: Eleven randomized controlled trials involving 890 patients were analyzed. We found that the addition of DEX to LAs significantly decreased pain scores at six postoperative time points (0.5, 1, 2, 4, 12, and 24 h) and significantly prolonged the time to the first analgesic request by patients. In addition, 24-hour postoperative analgesic consumption was decreased in the experimental group, and no significant difference in the incidence of nausea and vomiting was observed.

Conclusion: Our findings indicate that intraperitoneal instillation of DEX with LAs can reduce postoperative pain and prolong the time to first request analgesia after LC.

Objective: To investigate the value of the left lateral decubitus position in laparoscopic right posterior lobe tumor resection.

Patients and methods: The clinical data of patients who underwent laparoscopic right posterior lobectomy from January 2020 to March 2023 were retrospectively collected and divided into group A (left lateral decubitus position group, n=30) and group B (conventional position group, n=35) according to different body positions. Intraoperative and postoperative data were collected and compared between the 2 groups.

Results: The operation time (210.43±57.56 vs. 281.97±65.89, t =5.887, P <0.05), hilar occlusion time (23.97±14.25 vs. 35.79±12.62, t =4.791, P <0.05), intraoperative blood loss (162.14±72.61 vs. 239.65±113.56, t =5.713, P <0.05), postoperative feeding time (1.13±0.36 vs. 1.57±0.67, t =3.681, P <0.05), postoperative visual analog scale score (5.16±0.89 vs. 7.42±1.31, t =3.721, P <0.05), postoperative abdominal drainage tube indwelling time (4.58±1.34 vs. 5.42±1.52, t =4.553, P <0.05), incidence rate of complications (43.33% vs. 82.86%, χ 2 =11.075, P <0.05) in group A were lower than those in group B ( P <0.05). Symptoms/side effects (32.42±3.42 vs. 27.44±3.31, t =4.331, P <0.05), and there were significant differences in social function (33.55±2.56 vs. 29.31±3.32, t =4.863, P <0.05).

Conclusion: For right posterior lobe tumors of the liver, the left lateral decubitus position has many advantages in laparoscopic right posterior lobectomy, such as a wide field of view, simple steps, a short operation time, less bleeding, and a high postoperative quality of life. It is an effective treatment for right posterior lobe tumors of the liver and is worthy of being widely popularized.

Objective: To investigate the influence of endoscopic gallbladder stenting (EGBS) on subsequent cholecystectomy. We retrospectively compared the surgical outcomes of EGBS, followed by elective cholecystectomy with those of immediate cholecystectomy (IC).

Patients and methods: A total of 503 patients were included in this study. Patients who underwent EGBS as initial treatment for acute cholecystitis, followed by elective cholecystectomy, were included in the EGBS group and patients who underwent IC during hospitalization were included in the IC group. Propensity score matching analysis was used to compare the surgical outcomes. In addition, the factors that increased the amount of bleeding were examined by multivariate analysis after matching.

Results: Fifty-seven matched pairs were obtained after propensity matching the EGBS group and the IC group. The rate of laparoscopic cholecystectomy in the EGBS versus IC groups was 91.2% versus 49.1% ( P < 0.001). The amount of bleeding was 5 mL in the EGBS versus 188 mL in the IC group ( P < 0.001). In the EGBS and IC groups, multivariate analysis of factors associated with more blood loss revealed IC (odds ratio: 4.76, 95% CI: 1.25-20.76, P = 0.022) as an independent risk factor.

Conclusion: EGBS as the initial treatment for acute cholecystitis and subsequent elective cholecystectomy after the inflammation has disappeared can be performed in minimally invasive procedures and safely.
