RESUMEN
INTRODUCTION: Robotic-assisted metabolic and bariatric surgery (MBS) is gaining popularity. Revisional MBS is associated with higher perioperative morbidity compared to primary MBS. The optimal surgical approach to minimize complications in these complex cases is unclear. The goal of this study was to assess robot utilization in revisional MBS and compare laparoscopic and robotic revisional MBS outcomes in the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database. METHODS: A retrospective review of the MBSAQIP database was performed identifying revisional sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) cases from 2015 to 2022. Primary MBS, open/emergent cases, cases converted to another approach, and combined cases other than esophagogastroduodenoscopy were excluded. 30-Day outcomes for laparoscopic and robotic cases were compared using multivariate logistic regression adjusting for patient demographics, comorbidities, and operative variables. RESULTS: 41,404 Cases (14,474 SG; 26,930 RYGB) were identified. From 2015 to 2022, the percentage of revisional SG and RYGB cases performed robotically increased from 6.1% and 7.3% to 24.2% and 32.0% respectively. Laparoscopic SG had similar rates of overall morbidity, leak, bleeding, readmission, reoperation, and length of stay compared to robotic. Laparoscopic RYGB had significantly higher rates of overall morbidity (6.2% vs. 4.8%, p < 0.001, AOR 0.80 [0.70-0.93]), blood transfusion (1.5% vs. 1.0%, p < 0.05, AOR 0.74 [0.55-0.99]), superficial incisional SSI (1.2% vs. 0.4%, p < 0.001, AOR 0.30 [0.19-0.47]), and longer length of stay (1.87 vs. 1.76 days, p < 0.001) compared to robotic. Laparoscopic operative times were significantly shorter than robotic (SG: 86.4 ± 45.8 vs. 113.5 ± 51.7 min; RYGB: 130.7 ± 64.7 vs. 165.5 ± 66.8 min, p < 0.001). CONCLUSION: Robot utilization in revisional bariatric surgery is increasing. Robotic surgery has lower postoperative morbidity and shorter length of stay in revisional RYGB when compared to laparoscopic. Robotic platforms may have the capacity to improve the delivery of care for patients undergoing revisional bariatric surgery.
RESUMEN
BACKGROUND: Biosynthetic meshes afford the cost advantages of being made from fully synthetic material, but are also biodegradable, making them a versatile option that can be used in both clean and contaminated cases. The aim of this study is to evaluate the safety profile and long-term outcomes of using GORE BIO-A (BIO-A) as an adjunct to abdominal wall reconstruction in all wound classes. METHODS: A retrospective review identified patients undergoing abdominal hernia repair using BIO-A from October 2008 to June 2018. The primary outcome was hernia recurrence rate. Only patients with at least 6-month follow-up were included when looking at recurrence rates. Secondary outcomes included 30-day morbidity categorized according to CDC Surgical Site Infection Criteria, return to operating/procedure room (RTOR), 30-day readmission, length of stay (LOS), and mortality. RESULTS: A total of 207 patients were identified, CDC Wound Classification breakdown was 127 (61.4%), 41 (19.8%), 14 (6.8%), and 25 (12.1%) for wound classes I, II, III, and IV, respectively. Median follow-up was 55.4 months (range 0.2-162.4). Overall recurrence rate was 17.4%. Contaminated cases experienced higher recurrence rates (28.8% versus 10.4%, p = 0.002) at a mean follow up of 46.9 and 60.8 months for contaminated and clean patients, respectively. Recurrent patients had higher BMI (32.4 versus 28.4 kg/m2, p = 0.0011), larger hernias (162.2 versus 106.7 cm2, p = 0.10), higher LOS (11.1 versus 5.6 days, p = 0.0051), and higher RTOR rates (16.7% versus 5.6%, p = 0.053). 51 (24.5%) patients experienced some morbidity, including 19 (9.2%) surgical site occurences, 7 (3.4%) superficial surgical site infections, 16 (7.7%) deep surgical site infections, and 1 (0.5%) organ space infection. CONCLUSION: This study affirms the use of biosynthetic mesh as a cost-effective alternative in all wound classifications, yielding good outcomes, limited long-term complications, and low recurrence. rates.

Background: Esophageal diverticula were traditionally treated with open surgery, which is associated with significant morbidity and mortality rates. Management has shifted to minimally invasive approaches with several advantages. We examine outcomes in patients with esophageal diverticula treated with minimally invasive techniques by a multidisciplinary surgical team at a single center. Materials and Methods: A retrospective review of a prospectively maintained database was performed for patients who underwent minimally invasive surgery for esophageal diverticula at our institution from June 2010 to December 2022. Primary outcomes were 30-day morbidity and mortality rates. Secondary outcomes were symptom resolution, length of stay (LOS), readmission, and need for reintervention. Results: A total of 28 patients were identified. Twelve patients had pharyngeal diverticula, 7 patients had midesophageal diverticula, and 9 patients had epiphrenic diverticula. Thirty-day morbidity and readmission rates were 10.7% (3 patients), 1 pharyngeal (sepsis), 1 midesophageal (refractory nausea), and 1 epiphrenic (poor oral intake). There were no esophageal leaks. Average LOS was 2.3 days, with the pharyngeal group experiencing a significantly shorter LOS (1.3 days versus 3.4 days for midesophageal, P < .01 versus 2.8 days for epiphrenic, P < .05). Symptom resolution after initial operation was 78.6%. Reintervention rate was 17.9%, and symptom resolution after reintervention was 100%. There were no mortalities. Conclusion: This study demonstrates that esophageal diverticula can be repaired safely and efficiently when performed by a multidisciplinary team utilizing advanced minimally invasive endoscopic and robotic surgical techniques. We advocate for the management of this rare condition at a high-volume center with extensive experience in foregut surgery.

BACKGROUND: Percutaneous auricular nerve stimulation (neuromodulation) involves implanting electrodes around the ear and administering an electric current. A device is currently available within the USA cleared to treat symptoms from opioid withdrawal, and multiple reports suggest a possible postoperative analgesic effect. The current randomized controlled pilot study was undertaken to (1) determine the feasibility and optimize the protocol for a subsequent definitive clinical trial; and (2) estimate the treatment effect of auricular neuromodulation on postoperative pain and opioid consumption following two ambulatory surgical procedures. METHODS: Within the recovery room following cholecystectomy or hernia repair, an auricular neuromodulation device (NSS-2 Bridge, Masimo, Irvine, California, USA) was applied. Participants were randomized to 5 days of either electrical stimulation or sham in a double-blinded fashion. RESULTS: In the first 5 days, the median (IQR) pain level for active stimulation (n=15) was 0.6 (0.3-2.4) vs 2.6 (1.1-3.7) for the sham group (n=15) (p=0.041). Concurrently, the median oxycodone use for the active stimulation group was 0 mg (0-1), compared with 0 mg (0-3) for the sham group (p=0.524). Regarding the highest pain level experienced over the entire 8-day study period, only one participant (7%) who received active stimulation experienced severe pain, versus seven (47%) in those given sham (p=0.031). CONCLUSIONS: Percutaneous auricular neuromodulation reduced pain scores but not opioid requirements during the initial week after cholecystectomy and hernia repair. Given the ease of application as well as a lack of systemic side effects and reported complications, a definitive clinical trial appears warranted. TRIAL REGISTRATION NUMBER: NCT05521516.
RESUMEN
BACKGROUND: Xanthogranulomatous cholecystitis (XGC) is an uncommon variant of chronic cholecystitis which can resemble gallbladder adenocarcinoma (GAC) on preoperative imaging and present technical challenges in the performance of cholecystectomy. We examined our experience with each pathology to identify distinguishing characteristics that may guide patient counseling and surgical management. METHODS: A retrospective review of all pathologically confirmed cases of XGC and GAC following cholecystectomy between 2015 and 2021 at a single institution was performed. Clinical, biochemical, radiographic, and intraoperative features were compared. RESULTS: There were 37 cases of XGC and 20 cases of GAC. Patients with GAC were older (mean 70.3 years vs 58.0, p = 0.01) and exclusively female (100% vs 45.9%, p < 0.0001). There were no significant differences in accompanying symptoms between groups (nausea/vomiting, fevers, or jaundice). The mean maximum white blood cell count was elevated for XGC compared to GAC (16.4 vs 8.6 respectively, p = 0.044); however, there were no differences in the remainder of the biochemical profile, including bilirubin, liver transaminases, CEA, and CA 19-9. The presence of an intraluminal mass (61.1% vs 9.1%, p = 0.0001) and lymphadenopathy (18.8%. vs 0.0%, p = 0.045) were associated with malignancy, whereas gallbladder wall thickening as reported on imaging (87.9% vs 38.9%, p = 0.0008) and gallstones (76.5% vs. 50.0%, p = 0.053) were more often present with XGC. Cases of XGC more often had significant adhesions/inflammation (83.8% vs 55.0%, p = 0.03). CONCLUSION: Clinical features that may favor benign chronic cholecystitis over gallbladder adenocarcinoma include younger age, male gender, current or prior leukocytosis, and the absence of an intraluminal mass or lymphadenopathy. Laparoscopic cholecystectomy is a safe surgical option for equivocal presentations. Intraoperative frozen section or intentional staging of more extensive procedures based upon final histopathology are valuable surgical strategies.

BACKGROUND: Multidisciplinary approaches to weight loss have been shown to improve outcomes in bariatric patients. Few studies have been performed assessing the utility and compliance of fitness tracking devices after bariatric surgery. We aim to determine whether use of an activity tracking device assists bariatric patients in improving postoperative weight loss behaviors. METHODS: A fitness wearable was offered to patients undergoing bariatric surgery from 2019 to 2022. A telephone survey was conducted to elucidate the impact of the device on the patient's postoperative weight loss efforts 6 to 12 months after surgery. Weight loss outcomes of sleeve gastrectomy (SG) patients receiving the fitness wearable (FW) were compared to those of a group of SG patients who did not receive one (non-FW). RESULTS: Thirty-seven patients were given a fitness wearable, 20 of whom responded to our telephone survey. Five patients reported not using the device and were excluded. 88.2% reported that using the device had a positive impact on their overall lifestyle. Patients felt that using the fitness wearable to keeping track of their progress helped them both to achieve short-term fitness goals and sustain them in the long run. From the patients that utilized the device, 44.4% of those that discontinued felt like it helped them build a routine that they maintained even after they were no longer using it. Demographic data between FW and non-FW groups (age, sex, CCI, initial BMI, and surgery BMI) did not differ significantly. The FW group trended towards greater %EWL at 1 year post-operation (65.2% versus 52.4%, p = 0.066) and had significantly greater %TWL at 1 year post-operation (30.3% versus 22.3%, p = 0.02). CONCLUSION: The use of an activity tracking device enhances a patient's post-bariatric surgery experience, serving to keep patients informed and motivated, and leading to improved activity that may translate to better weight loss outcomes.

BACKGROUND: No platform for objective, synchronous and on-line evaluation of both intraoperative error and surgeon physiology yet exists. Electrokardiogram (EKG) metrics have been associated with cognitive and affective features that are known to impact surgical performance but have not yet been analyzed in conjunction with real-time error signals using objective, real-time methods. METHODS: EKGs and operating console point-of-views (POVs) for fifteen general surgery residents and five non-medically trained participants were captured during three simulated robotic-assisted surgery (RAS) procedures. Time and frequency-domain EKG statistics were extracted from recorded EKGs. Intraoperative errors were detected from operating console POV videos. EKG statistics were synchronized with intraoperative error signals. RESULTS: Relative to personalized baselines, IBI, SDNN and RMSSD decreased 0.15% (S.E. 3.603e-04; P = 3.25e-05), 3.08% (S.E. 1.603e-03; P < 2e-16) and 1.19% (S.E. 2.631e-03; P = 5.66e-06), respectively, during error. Relative LF RMS power decreased 1.44% (S.E. 2.337e-03; P = 8.38e-10), and relative HF RMS power increased 5.51% (S.E. 1.945e-03; P < 2e-16). CONCLUSIONS: Use of a novel, on-line biometric and operating room data capture and analysis platform enabled detection of distinct operator physiological changes during intraoperative errors. Monitoring operator EKG metrics during surgery may help improve patient outcomes through real-time assessments of intraoperative surgical proficiency and perceived difficulty as well as inform personalized surgical skills development.

BACKGROUND: Enhanced recovery protocols have been developed to improve perioperative outcomes; however, there is ongoing concern for aspiration with recent oral intake in patients with obesity, who may be predisposed to impaired gastrointestinal motility and greater gastric volumes. We aim to study the safety of a 300-mL preoperative carbohydrate-loading drink preceding bariatric surgery. STUDY DESIGN: Data were collected prospectively from patients undergoing primary bariatric surgery. All bariatric patients at our institution are prescribed a proton pump inhibitor for 4 weeks before surgery and undergo a screening preoperative esophagogastroduodenoscopy (EGD) before surgery with a traditional 8-hour fast (NOCARB), followed by an intraoperative day-of-operation EGD with carbohydrate loading (CARB) 2 to 4 hours before incision. Gastric volumes and pH are measured after being endoscopically suctioned via direct visualization during both settings. RESULTS: We identified 203 patients: 94 patients (46.3%) in the CARB group and 109 patients (53.7%) in the NOCARB group. The patients were 82.3% female with a mean age of 42.8 years and average BMI of 41.7 kg/m 2 . There was no difference in gastric volume between NOCARB and CARB (17.0 vs 16.1 mL, p = 0.59). The NOCARB group had lower pH values than the CARB group (2.8 vs 3.8, p = 0.001). Subset analysis of 23 patients who had measurements on both screening and intraoperative EGD revealed lower gastric volumes in CARB patients (13.3 vs 18.3, p < 0.0001). CONCLUSIONS: When included in an enhanced recovery protocol, proton pump inhibitor use and preoperative carbohydrate loading 2 to 4 hours before bariatric surgery does not increase aspiration risk based on gastric volumes and pH and should be strongly considered in all eligible bariatric patients.

BACKGROUND: The coronavirus pandemic has caused a worldwide health crisis. Bariatric patients require extensive pre- and post-operative follow-up, which may be less feasible during public health social distancing mandates. We assessed the impact of the pandemic on the behaviors and weight loss outcomes of our pre- and post-operative bariatric patients. METHODS: A retrospective review of a prospectively maintained database identified patients who underwent either sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) at a single institution between March 2018 and May 2020. A cohort undergoing surgery within 12 months before the pandemic as well as a cohort undergoing a medically supervised diet prior to surgery was surveyed regarding pre- and post-COVID-19 lifestyle habits. Excess weight loss (EWL) outcomes from a group of pre-COVID surgical patients were compared to that of a group of post-COVID surgical patients. Primary outcome was whether the lockdown changed 1-year weight loss outcomes. Secondary outcome was whether patient lifestyle behaviors were changed during the pandemic. RESULTS: There was no difference in 1-year EWL between pre- and post-COVID SG patients (51.7% versus 55.9%, p = 0.35), or between pre- and post-COVID RYGB patients (88.9% versus 80.4%, p = 0.42). Pre-stay-at-home order, 91.8% endorsed physical activity compared to 80.3% post-stay-at-home order (p = 0.0025). Mean physical activity decreased from 4.2 h/week to 2.7 h/week after the stay-at-home order (p < 0.0001). Additionally, 41.3% reported worsened dietary habits post-stay-at-home order. CONCLUSION: The COVID-19 pandemic has greatly impacted the behaviors of bariatric surgery patients. Despite deterioration of lifestyle habits, 1-year weight loss outcomes after bariatric surgery remained the same before and after the instatement of social distancing measures. In the short term, the biological effect of metabolic procedures may mask the effects of suboptimal diet and physical activity, but more studies are necessary to better assess the impact of COVID-19 on outcomes after bariatric surgery.

INTRODUCTION: Post-operative gastroesophageal reflux disease (GERD) remains a significant morbidity following sleeve gastrectomy (SG). We aim to evaluate the incidence and impact within a single center experience. MATERIALS AND METHODS: A retrospective review of a prospectively maintained database was performed identifying laparoscopic or robotic SG patients. Primary outcomes included weight loss, rates of post-operative GERD (de-novo or aggravated), and re-intervention. Subgroup analysis was performed between patients with (Group 1) and without (Group 2) post-operative GERD. De-novo GERD and aggravated was defined as persistent GERD complaints or new/increased PPI usage in GERD naive or prior GERD patients, respectively. RESULTS: 392 patients were identified between 2014 and 2019. Average demographics: age 42.3 (18-84) years, Charlson Comorbidity Index (CCI) 1.12 (0-10), and body mass index (BMI) 47.7 (28-100). 98% were performed laparoscopically. Average excess weight loss (EWL) was 51.0% and 46.4% at 1 and 2 years post-operatively. Average follow up was 516 (6-2694) days. 69 (17%) patients developed post operative de-novo or aggravated GERD. Group 1 had significantly higher EWL at 9 months (57% vs 47%, p 0.003). 13 (3%) patients required operative re-intervention for GERD and other morbidities: 4 RYGB conversions, 4 diagnostic laparoscopies, 3 HHR, 1 MSA placement. Group 1 had higher rates of post-operative intervention (14% vs 1%, p 0.0001). Subanalysis demonstrated that Group 1 had elevated preoperative DeMeester scores on pH testing (34.8 vs 18.9, p 0.03). De-novo GERD had an elevated post-operative total acid exposure when compared to aggravated GERD (12.7% vs 7.0% p 0.03). No significant differences were found between preoperative endoscopy findings, pre and postoperative total acid exposure, post-operative DeMeester scores, and high-resolution manometry values regarding de-novo/aggravated GERD development. CONCLUSION: Preoperative DeMeester scores may serve as risk indicators regarding post-operative GERD. Outcomes such as reintervention remain elevated in post-operative GERD patients.

BACKGROUND: The legalization of cannabis in several states has led to increased documented use in the population. Bariatric surgery patients are no exception with estimates of anywhere from 6 to 8%. Cannabis is known to be associated with increased appetite, mood disorders, hyperphagia, and rarely, hyperemesis, which can potentially affect post-surgical weight loss. We aim to study the differences in bariatric surgery outcomes between cannabis users and non-users. METHODS: A retrospective review identified patients undergoing bariatric surgery. Patients were divided into two groups, cannabis users (CU) and non-cannabis users (non-CU). Cannabis users (defined as using at least once weekly) and a group of non-users were called to obtain additional information. Primary outcome was weight loss. Secondary outcomes included incidence of post-operative nausea and vomiting (PONV), length of stay (LOS), readmission, and need for additional intervention. RESULTS: A cohort of 364 sleeve gastrectomy patients met inclusion criteria, 31 (8.5%) CU and 333 (91.5%) non-CU. There was no difference in EWL between CU and non-CU at 1 week, 1 month, 3 months, 6 months, 9 months, 1 year, and 2 years. However, the CU group trended towards greater EWL at 3 years (52.9% vs. 38.1%, p = 0.094) and at 5 years (49.8% vs. 32.7%, p = 0.068). There were no significant differences between CU and non-CU with respect to either incidence or severity of PONV at one year after surgery or longer follow-up. CONCLUSION: Cannabis users did not experience inferior weight loss after bariatric surgery despite common assumptions that appetite stimulation can lead to suboptimal weight loss outcomes. Our findings add to other work challenging this dogma. Larger, long-term, multicenter studies are warranted.

BACKGROUND: Laparoscopic cholecystectomy with fluorescent cholangiography using indocyanine green dye (FC) identifies extrahepatic biliary structures, potentially augmenting the critical view of safety. We aim to describe trends for the largest single-center cohort of patients undergoing FC in laparoscopic cholecystectomy. STUDY DESIGN: A retrospective review of a prospectively maintained database identified patients undergoing laparoscopic cholecystectomy with FC at a single academic institution. Patient factors included age, sex, BMI, and American Society of Anesthesiologists score. Outcomes included operative time, conversion to open procedure, biliary injury, length of stay, and complications. RESULTS: A total of 828 patients underwent FC. Of these, 74.3% were female, the mean age was 50.4 years, and the average BMI 28.8 kg/m 2 . Mean operating room time was 68.6 minutes. There were no mortalities or common bile duct injuries. Morbidities included 4 bile leaks and 1 retained stone. Six patients required conversion to an open approach. Operative time, length of stay, and open conversion significantly decreased after a standard indocyanine green protocol (p < 0.05). Compared with white light, FC demonstrated lower operative times (99 vs 68 minutes), length of stay (1.4 vs 0.4 days), open conversions (8% vs 0.7%), emergency department visits (13% vs 8%) and drain placements (12% vs 3%) (all p < 0.05). Patients with BMI greater than 30 saw elevated operative times and length of stay. CONCLUSIONS: In conclusion, this paper demonstrates improved operative outcomes with the use of FC through the consistent ability to delineate biliary anatomy, even in the setting of complex anatomy. No common bile duct injuries have occurred in our 7-year experience with FC. We recommend FC as the standard of care when performing laparoscopic cholecystectomies.

BACKGROUND: Potential complications after inguinal hernia repair include uncontrolled post-operative pain and post-operative urinary retention (POUR). Enhanced Recovery After Surgery (ERAS) protocols aim to mitigate post-operative morbidity. We study the impact of ERAS measures alongside discharge without a narcotic prescription on post-operative pain and POUR after minimally invasive inguinal hernia repair. METHODS: A retrospective review of a prospectively maintained database identified patients that underwent minimally invasive inguinal hernia repair at a single institution. Intra-operative data included operative time, narcotic usage, non-narcotic adjunct medication, and fluid administration. Primary outcomes included rates of POUR and uncontrolled post-operative pain. Operations performed after 2018 were included in the ERAS cohort. Uncontrolled post-operative pain was defined as needing additional narcotic prescriptions, admission, or ER visits for post-operative pain. POUR was defined as requiring an indwelling urethral catheter at discharge, admission for retention, or returning to the ER for urinary retention. RESULTS: Between January 2008 and March 2021, 1097 patients who underwent minimally invasive inguinal hernia repair were identified. 91.3% of these procedures were laparoscopic and 8.7% were robotic. Average patient age was 57.4 years, 93% were male. Patients receiving care after initiation of the ERAS protocol were significantly less likely to experience POUR when compared to their prior counterparts (1.4% vs. 4.2% p = 0.01); there was no difference in post-operative pain complications (1.4% vs. 2.9% p = 0.15). Patients who were discharged without a narcotic prescription had 0% incidence of POUR. Significant differences were found between the ERAS and non-ERAS cohort regarding narcotic usage and fluid administration. Age, higher fluid volume, and higher narcotic usage were found to be risk factors for POUR while ERAS, sugammadex, and dexamethasone were found to be protective. CONCLUSION: Implementation of an ambulatory ERAS protocol can significantly decrease urinary retention and narcotic usage rates after minimally invasive inguinal hernia repair.

BACKGROUND: Early experience with indocyanine green-based fluorescent cholangiography during laparoscopic cholecystectomy suggests the potential to improve outcomes. However, the cost-effectiveness of routine use has not been studied. Our objective was to evaluate the cost-effectiveness of fluorescent cholangiography versus standard bright light laparoscopic cholecystectomy for noncancerous gallbladder disease. METHODS: A Markov model decision analysis was performed comparing fluorescent cholangiography versus standard bright light laparoscopic cholecystectomy alone. Probabilities of outcomes, survival, toxicities, quality-adjusted life-years, and associated costs were determined from literature review and pooled analysis of currently available studies on fluorescent cholangiography (n = 37). Uncertainty in the model parameters was evaluated with 1-way and probabilistic sensitivity analyses, varying parameters up to 40% of their means. Cost-effectiveness was measured with an incremental cost-effectiveness ratio expressed as the dollar amount per quality-adjusted life-year. RESULTS: The model predicted that fluorescent cholangiography reduces lifetime costs by $1,235 per patient and improves effectiveness by 0.09 quality-adjusted life-years compared to standard bright light laparoscopic cholecystectomy. Reduced costs were due to a decreased operative duration (21.20 minutes, P < .0001) and rate of conversion to open (1.62% vs 6.70%, P < .0001) associated with fluorescent cholangiography. The model was not influenced by the rate of bile duct injury. Probabilistic sensitivity analysis found that fluorescent cholangiography was both more effective and less costly in 98.83% of model iterations at a willingness-to-pay threshold of $100,000/quality-adjusted life year. CONCLUSION: The current evidence favors routine use of fluorescent cholangiography during laparoscopic cholecystectomy as a cost-effective surgical strategy. Our model predicts that fluorescent cholangiography reduces costs while improving health outcomes, suggesting fluorescence imaging may be considered standard surgical management for noncancerous gallbladder disease. Further study with prospective trials should be considered to verify findings of this predictive model.

Introduction: Paraesophageal hernias readily affect the elderly with a median age of presentation between 65 and 75 years. Laparoscopic paraesophageal hernia repair (PEHR) is a technically challenging operation with potential for dire complications. Advanced age and medical comorbidities may heighten perioperative risk and limit surgical candidacy, potentially refusing patients an opportunity toward symptom resolution. Given the increased prevalence in the elderly and associated surgical risks, we aim to assess age as an independent risk factor for perioperative morbidity and mortality after PEHR. Methods: A retrospective analysis using a prospectively maintained database assessed patients undergoing PEHR from 2007 to 2018. Patients were stratified by age: Group A (age <65 years), Group B (65≤ age <80 years), and Group C (age ≥80 years). Patient demographics, preoperative symptoms, postoperative outcomes, and mortality rate were analyzed. Barium esophagram was performed on symptomatic postsurgical patients. Recurrence was confirmed radiologically. Results: In total, 143 patients underwent laparoscopic (94.4%) or robotic-assisted (5.6%) PEHR. Average age per group was Group A (n = 49) 55.4 years (standard deviation [SD] ±8.91), Group B (n = 76) 71.4 years (SD ±4.40), and Group C (n = 17) 84.1 (years) (SD ±3.37). Group C had significantly higher rates of nonelective surgery (P = .018), preoperative weight loss (P = .014), hypertension (P = .031), ischemic heart disease (P = .001), and cancer (P = .039); preoperative body mass index was significantly lower (P = .048). Charlson comorbidity index differences between groups were significant (2.00 versus 3.61 versus 5.28, P < .001). Median follow-up was 426 days (6-3199). Symptom improvement was seen in 78.3% of patients. Recurrence and reoperation rates were not significantly different between groups. No differences were seen in mortality, length of stay, or postoperative complications between groups. Conclusions: PEHR in elderly patients proved to be safe and effective. Avoidance of emergent intervention may be achieved through a judicious elective approach to this anatomic problem. Symptom resolution and quality-of-life improvement can be safely achieved with surgical repair in this patient population, demonstrating that age is truly just a number for PEHR.

Surgeons operate in mentally and physically demanding workspaces where the impact of error is highly consequential. Accurately characterizing the neurophysiology of surgeons during intraoperative error will help guide more accurate performance assessment and precision training for surgeons and other teleoperators. To better understand the neurophysiology of intraoperative error, we build and deploy a system for intraoperative error detection and electroencephalography (EEG) signal synchronization during robot-assisted surgery (RAS). We then examine the association between EEG data and detected errors. Our results suggest that there are significant EEG changes during intraoperative error that are detectable irrespective of surgical experience level.
RESUMEN
BACKGROUND: Opioid use in the U.S. has increased dramatically over the last 15 years, recently being declared a public health emergency. Opioid use is associated with esophageal dysmotility lending to a confusing clinical picture compared to true achalasia. Patients exhibit symptoms and elicit diagnostic results consistent with esophageal motility disorders, in particular type III achalasia. Modified therapeutic strategies and outcomes become challenging. Differentiating true achalasia from opioid-induced achalasia is critical. Conventional surgical interventions, i.e., myotomy, are ineffective in the absence of true achalasia. We assess the utility of esophageal muscle layer mapping with endoscopic ultrasound (EUS) in distinguishing primary from opioid-induced achalasia. METHODS: From 2016 to 2019, patients with abnormal manometry and suspected achalasia underwent esophagogastroduodenoscopy and EUS mapping of esophageal round muscle layer thickness. Maximum round layer thickness and length of round muscle layer thickness > 1.8 mm were collected and compared between opioid users and non-opioid users using Wilcoxon Rank sum test. RESULTS: 45 patients were included: 12 opioid users, 33 non-opioid users. Mean age 56.8 years (range 24-93), 53.3% male patients. Mean BMI in the opioid-induced achalasia group was 30.2 kg/m2, mean BMI in the primary achalasia group 26.8 kg/m2 (p = 0.11). In comparing endoscopic maximum round layer thickness between groups, non-opioid patients had a thicker round muscle layer (2.7 mm vs 1.8 mm, p = 0.05). Length of abnormally thickened esophageal muscle (greater than 1.8 mm) also differed between the two groups; patients on opioids had a shorter length of thickening (4.0 cm vs 0.0 cm, p = 0.04). Intervention rate was higher in the non-opioid group (p = 0.79). Of the patients that underwent therapeutic intervention, symptom resolution was higher in the non-opioid group (p = 0.002), while re-intervention post-procedure for persistent symptomatology was elevated in the opioid subset (p = 0.06). Patients in the opioid group were less likely to undergo invasive treatment (Heller). As of 2017 all interventions in the opioid group have been endoscopic. CONCLUSION: Endoscopic ultrasound is an essential tool that has improved our treatment algorithm for suspected achalasia in patients with chronic opioid usage. Incorporation of EUS findings into treatment approach may prevent unnecessary surgery in opioid users.

INTRODUCTION: Standard of care for locally advanced esophageal carcinoma is neoadjuvant chemoradiation (nCRT) and surgical resection 4-8 weeks after completion of nCRT. It is recommended that the CRT to surgery interval not exceed 90 days. Many patients do not undergo surgery within this timeframe due to patient/physician preference, complete clinical response, or poor performance status. Select patients are offered salvage esophagectomy (SE), defined in two ways: resection for recurrent/persistent disease after complete response to definitive CRT (dCRT) or esophagectomy performed > 90 days after completion of nCRT. Salvage esophagectomy reportedly has higher postoperative morbidity and poor survival outcomes. In this study, we assessed outcomes, overall, and disease-free survival of patients undergoing salvage esophagectomy by both definitions (recurrent/persistent disease after dCRT and/or > 90 days), compared to planned (resection after nCRT/within 90 days) esophagectomy (PE). MATERIALS AND METHODS: Retrospective review of a prospectively maintained database identified patients who underwent minimally invasive esophagectomy at a single institution from 2009 to 2019. Esophagectomy for benign disease and patients who did not receive nCRT were excluded. Outcomes included postoperative complications, length of stay (LOS), disease-free survival, and overall survival. RESULTS: 97 patients underwent minimally invasive esophageal resection for esophageal carcinoma. 89.7% of patients were male. Mean age was 64.9 years (range 36-85 years). 94.8% of patients had adenocarcinoma, with 16 transthoracic and 81 transhiatal approaches. On comparing planned esophagectomy (n = 87) to esophagectomy after dCRT failure (n = 10), no significant differences were identified in overall survival (p = 0.73), disease-free survival (p = 0.32), 30-day or major complication rate, anastomotic leak, or LOS. Similarly, when comparing esophagectomy < 90 days after CRT (n = 62) to > 90 days after CRT completion (n = 35), no significant differences were identified in overall survival (p = 0.39), disease-free survival (p = 0.71), 30-day or major complication rate, LOS, or anastomotic leak rate between groups. In this comparison, local recurrence was noted to be elevated with SE as compared to PE (64.3% vs. 25.0%, p = 0.04). CONCLUSION: Overall survival and disease-free survival were equivalent between SE and PE. Local recurrence was noted to be increased with SE, though this did not appear to affect survival. Although planned esophagectomy remains the standard of care, salvage esophagectomy has comparable outcomes and is appropriate for selected patients.
