ABSTRACT
BACKGROUND: Sleeve gastrectomy has become a gold standard in addressing medically refractory obesity. Robotic platforms are becoming more utilized, however, data on its cost-effectiveness compared to laparoscopy remain controversial (1-3). At NYU Langone Health, many of the bariatric surgeons adopted robotic surgery as part of their practices starting in 2021. We present a retrospective cost analysis of laparoscopic sleeve gastrectomy (LSG) vs. robotic sleeve gastrectomy (RSG) at New York University (NYU) Langone Health campuses. METHODS: All adult patients ages 18-65 who underwent LSG or RSG from 202 to 2023 at NYU Langone Health campuses (Manhattan, Long Island, and Brooklyn) were evaluated via electronic medical records and MBSAQIP 30-day follow-up data. Patients with prior bariatric surgery were excluded. Complication-related ICD-10/CPT codes are collected and readmission costs will be estimated from ICD codes using the lower limit of CMS transparent NYU standard charges (3). Direct charge data for surgery and length of stay cost data were also obtained. Statistical T-test and chi-squared analysis were used to compare groups. RESULTS: Direct operating cost data at NYU Health Campuses demonstrated RSG was associated with 4% higher total charges, due to higher OR charges, robotic-specific supplies, and more post-op ED visits. CONCLUSIONS: RSG was associated with higher overall hospital charges compared to LSG, though there are multiple contributing factors. More research is needed to identify cost saving measures. This study is retrospective in nature, and does not include indirect costs nor reimbursement. Direct operating costs, per contractual agreement with suppliers, are only given as percentages. Data are limited to 30-day follow-up.
ABSTRACT
We describe the case of a patient with extranodal marginal zone mucosa-associated lymphoid tissue (MALT) lymphoma of the gallbladder discovered incidentally after elective cholecystectomy. A 76-year-old female with a history of non-Hodgkin's lymphoma of the right breast and rectal cancer stage Tis requiring trans-anal excision presented with chronic intermittent abdominal pain. Computed tomography (CT) scan showed multiple calcified gallstones impacted in the gallbladder, with no evidence of enlarging lymphadenopathy indicating an elective cholecystectomy. The intra- and post-operative courses were unremarkable, but pathology review revealed immunohistochemistry positive for CD20 and BCL-2 with a Ki67 proliferation index of 5%, which was diagnostic of extranodal marginal zone MALT lymphoma of the gallbladder. The patient was followed up by a medical oncologist, and after extensive discussion, the decision was made to continue observation with close monitoring without systemic chemotherapy given the asymptomatic presentation. We also examined the pertinent literature to MALT lymphoma of the gallbladder and discussed theories suggested for its pathophysiology.
ABSTRACT
BACKGROUND: Many insurance companies mandate medically supervised weight loss programs (MSWLPs) prior to bariatric surgery. This retrospective study aims to elucidate whether the average 6-month preoperative medical-management period decreases preoperative BMI for those with BMI ≥ 50. METHODS: All adult patients with bariatric consultation at any time at the New York University Langone Health campuses during the period 2015 to 2021 were evaluated via electronic medical records. Only patients with ≥ BMI 50, without previous bariatric surgeries, and those with 6-month insurance-mandated medical visits were included. A paired t-test was performed on the difference in BMI and percent-weight loss among the subjects at least 6 months before surgery and on the day of surgery. RESULTS: Of the 130 patients with BMI ≥ 50, undergoing preoperative 6-month office weigh-ins, the mean difference in BMI was - 1.51 (P < 0.01). The mean total body weight loss was 4.8% (P < 0.01). There were no intraoperative complications nor 30-day complications or mortality in the group. CONCLUSIONS: We found that there was weight loss during the 6-month insurance-mandated medical management prior to surgery, but the amount (4.8%) did not reach the goal target of 10% of body weight. We found that there were no complications and question the need for prolonged delay to surgery.

BACKGROUND: Post-herniorrhaphy pain is common with an estimated 8-10% incidence of mesh-related complications, requiring mesh explantation in up to 6% of cases, most commonly after inguinal hernia repairs. Reoperation for mesh explantation poses a surgical challenge due to adhesions, scarring and mesh incorporation to the surrounding tissues. Robotic technology provides a versatile platform for enhanced exposure to tackle these complex cases. We aim to share our experience with a novel robotic approach to address these complex cases. METHODS: A descriptive, retrospective analysis of patients undergoing a robotic mesh explantation (RoME) for mesh-related chronic pain, or recurrent ventral hernia by two surgeons between the period of March 2016 and January of 2020. The patients were evaluated for resolution of mesh related abdominal pain as well as early post-operative complications. RoME was performed with concomitant hernia repair in cases of recurrences. RESULTS: Twenty-nine patients underwent a robotic mesh explantation (RoME) for mesh-related chronic pain, or recurrent ventral hernia between March 2016 and January of 2020. Nineteen patients (65.5%) had a prior inguinal hernia repair and 10 patients (34.5%) had a prior ventral hernia repair. Indications for mesh removal included chronic pain with or without hernia recurrence. Seventeen patients (58.6%) reported improvement or resolution of pain postoperatively (63% with a prior inguinal hernia repair and 50% of patients with a prior ventral hernia repair). Five patients (17.2%) required mesh reinforcement after explantation. Nineteen patients (65.5%) underwent mesh explantation with primary fascial closure or no mesh reinforcement. The mean follow-up was 36.4 days. The most common postoperative complication was seroma formation (6.8%), with one reported recurrence (3.4%). CONCLUSION: Robotic mesh explantation in challenging cases due to the effect of chronic scarring, adhesions and mesh incorporation to the surrounding tissues is safe and provides an advantageous platform for concomitant hernia repair in these complex cases.

BACKGROUND: During the past decade, laparoscopic adjustable gastric banding (LAGB) was one of the most popular surgical procedures in treating morbid obesity. Long-term effects, specifically on esophageal motility, of LAGB have not been well described in the literature despite the high prevalence of reoperations and post-operative dysphagia. We aimed to characterize esophageal dysmotility after long-term follow-up using data of high-resolution esophageal manometry (HRM) performed in patients who presented for LAGB removal. The research was conducted in Academic Hospital Center in the USA. METHODS: Research was conducted with approval from the institution's Institutional Review Board. We included 25 consecutive patients who were requesting removal of the band or revisional bariatric surgery. All patients underwent HRM between 2011 and 2015. RESULTS: A Fisher's exact test two-sided p value 0.41 shows no statistically significant difference in proportions of normal motility or impaired motility between asymptomatic and symptomatic patients. CONCLUSIONS: Patients with a history of LABG can have esophageal dysmotility whether they are symptomatic or asymptomatic. Based on existing literature, we recommend pre-operative manometry in these patients requesting revisional surgery.

STUDY OBJECTIVE: To evaluate the comorbidities and surgical factors involved in the genesis of intraoperative pressure ulcers. DESIGN: Retrospective chart review. SETTING: Anesthesiology department of a university medical center. MEASUREMENTS: The charts of 222 patients with varying illness, who underwent an operation of at least two hours' duration, were analyzed retrospectively. Data on surgery type, case length, comorbidities, intraoperative surgical position, and area of ulceration were recorded. MAIN RESULTS: Risk factors for intraoperative pressure ulcer development include surgical times of 4 hours or longer; comorbidities affecting tissue perfusion (namely, diabetes, hypertension, and nonspecific cardiac issues); supine placement during surgery; and abdominal, noncardiac thoracic, and orthopedic operations. Regions of the body most at risk for ulceration include the coccygeal/sacral region, the buttocks, genitalia, and heels. CONCLUSIONS: Pressure ulcers are a costly, debilitating, and avoidable complication of surgery.
