RESUMEN
BACKGROUND: Conversion of Nissen fundoplication to Roux-en-Y (RnY) anatomy may be indicated in patients with post-surgical complications or who fail to achieve durable control of their disease. Herein we describe the largest series of patients at a single institution who underwent minimally invasive conversion of Nissen fundoplication to RnY reconstruction. METHODS: All patients with prior Nissen fundoplication which were converted to RnY anatomy at our institution from March 2009 through November 2017 were retrospectively reviewed and analyzed. Patients were identified based on CPT codes and the description of the operation performed. All cases with attempted minimally invasive approach were included for analysis. RESULTS: Fifty patients underwent conversion from prior Nissen fundoplication to RnY anatomy during the study period. The cohort was 84.0% female with a mean age of 53.5 years and a median body mass index of 36.7 kg/m2. Thirteen patients (26.0%) had multiple prior foregut operations. Complications from fundoplication that warranted revision included recurrent hiatal hernia (n = 16), post-surgical gastroparesis (n = 10), and mechanical complications from the wrap (n = 8). An additional fourteen patients underwent conversion to RnY for metabolic disease. The mean operative time and estimated blood loss were 266 min and 132 mL, respectively, with all but one (98.0%) completed with a minimally invasive approach. The median length of stay was 5 days. Complications included marginal ulcer (n = 2), superficial surgical site infection (n = 2), anastomotic leak (n = 2), and one case each of pulmonary embolism, small bowel obstruction, and gastrointestinal bleeding. There were no mortalities at a median follow-up of 12.4 months. CONCLUSIONS: Conversion of prior Nissen fundoplication to RnY anatomy is technically challenging, although it is safe and feasible even in the setting of multiple prior foregut operations. A minimally invasive approach should be offered to patients by surgeons with experience in revisional foregut and bariatric surgery.

BACKGROUND: Gastroparesis is a debilitating functional disorder of the stomach marked by delayed gastric emptying in the absence of mechanical obstruction. Patients with severe, refractory symptoms may ultimately be managed with Roux-en-Y reconstruction; however, it is unclear whether the stomach should be left in situ, similar to a conventional gastric bypass, or resected as in gastrectomy. METHODS: All patients undergoing Roux-en-Y for the treatment of gastroparesis (GP) at our institution from September 2010 through March 2018 were retrospectively reviewed. Patients with prior gastric resection or whose primary operative indication was not gastroparesis were excluded from analysis. RESULTS: Twenty-six patients underwent Roux-en-Y with stomach left in situ (RY-SIS) and twenty-seven patients underwent gastrectomy with Roux-en-Y reconstruction during the study period. The mean age was 49.7 years in the RY-SIS cohort and 48.5 years in the gastrectomy cohort. Etiology of GP was similar between the two cohorts. Patients undergoing gastrectomy were more likely to have previous interventions for GP (63.0% vs. 26.9%). RY-SIS was associated with a shorter operative time (155 vs. 223 min), less blood loss (24 vs. 130 mL), and shorter length of stay (4.0 vs. 7.2 days). Twelve patients (44.4%) had complications within 30 days following gastrectomy compared to two patients (7.7%) following RY-SIS (p = 0.001). Patients in the RY-SIS cohort were more likely to require further subsequent surgical intervention for GP (23.1% vs. 3.7%, p = 0.04). At last follow-up, there were no differences in reported GP symptoms or symptom scoring. CONCLUSIONS: Gastrectomy was associated with greater perioperative morbidity compared to leaving the stomach in situ. Symptomatic improvement at intermediate follow-up was equivalent following either procedure. However, patients undergoing RY-SIS were more likely to require subsequent surgical intervention, suggesting that gastrectomy may be a more definitive operation for the management of medically refractory gastroparesis.

BACKGROUND: While per-oral pyloromyotomy (POP) has shown promise as a novel endoscopic procedure to treat medically refractory gastroparesis, standardized care pathways are not well-defined. We aimed to compare the safety and cost of same-day discharge (SDD) after POP with inpatient stay overnight or longer. METHODS: All patients with SDD after POP between January 2016 and May 2018 were retrospectively identified from a prospectively maintained registry. Propensity scores considering gender, age, gastroparesis etiology, and American Society of Anesthesiologists (ASA) class were used to match a comparison group which stayed overnight or longer. Statistical tests included two-sample t tests for continuous variables, Fisher's exact test for categorical variables, and paired sample t tests for within-group comparisons with repeated measures. RESULTS: Fifty-four patients who underwent POP with SDD during the study period were propensity-matched with 54 patients with inpatient recovery. The SDD cohort was 85.2% female with a mean age of 44.8 years and median ASA class 3. The etiology of gastroparesis was idiopathic in 53.7% (n = 29), diabetic in 29.6% (n = 16), and post-surgical in 11.1% (n = 6). Operative time was shorter in the SDD cohort (25.4 vs. 31.3 min, p = 0.02). The mean post-procedure recovery time was 4 h in patients with SDD and 29.3 h in the inpatient cohort (p < 0.001). There was a trend towards less readmissions with SDD (7.4% vs. 18.5%, p = 0.08). There was no increased risk of complications with SDD (1.9% vs. 3.7%, p = 0.57). Compared to inpatient recovery, the average total cost for the procedure, recovery, and all subsequent care within 30 days was 26.0% less with SDD (p < 0.001). CONCLUSIONS: Following POP, patients can be safely discharged the same day with low risk of both complications and readmission. Total costs in the complete perioperative period are significantly less with SDD compared to inpatient recovery.

BACKGROUND: Gastroparesis is a debilitating functional disorder of the stomach characterized by delayed gastric emptying absent an obstructive etiology. Surgical or endoscopic disruption of the pylorus has been utilized to treat this disease, but there is little evidence comparing laparoscopic pyloroplasty (LP) with endoscopic per-oral pyloromyotomy (POP). Herein we describe our experience at our institution using a propensity-matched cohort study to compare outcomes between these procedures. METHODS: All patients who underwent LP for the treatment of gastroparesis from October 2014 through September 2017 at our institution were retrospectively reviewed. Propensity scoring was used to match these patients 1:1 to patients undergoing POP during this time period based on gender, age, and etiology of gastroparesis. Symptom scores using the Gastroparesis Cardinal Symptom Index (GCSI), scintigraphic gastric emptying studies (GES), and perioperative outcomes were compared between matched cohorts. Thirty patients underwent LP for gastroparesis during the study period which were matched 1:1 with patients undergoing POP. The etiology of gastroparesis was 63.3% idiopathic (n = 19), 20.0% post-surgical (n = 6), and 16.7% diabetic (n = 5) in both cohorts. RESULTS: Patients who underwent LP had a longer average length of stay (4.6 vs. 1.4 days, p = 0.003), operative time (99.3 vs. 33.9 min, p < 0.001), and estimated blood loss (12.9 vs. 0.4 mL, p < 0.001). There were more complications in the LP cohort (16.7 vs. 3.3%, p = 0.086), which included surgical site infection (6.7 vs. 0%, p = 0.153), pneumonia (6.7 vs. 0.0%, p = 0.153), and unplanned ICU admission (10.0 vs. 0.0%, p = 0.078). LP and POP both resulted in similar, significant improvements in both in GCSI scores and objective gastric emptying. CONCLUSIONS: Per-oral endoscopic pyloromyotomy (POP) is safe and effective for the treatment of medical refractory gastroparesis. POP has less perioperative morbidity compared to LP with comparative functional outcomes.

INTRODUCTION: Magnet-assisted surgery is a new platform within minimally invasive surgery. The Levita™ Magnetic Surgical System, the first magnetic surgical system to receive Food and Drug Administration (FDA) approval, includes a deployable, magnetic grasper and an external magnet that is used to manipulate the grasper within the peritoneal cavity. This system is currently approved for patients undergoing laparoscopic cholecystectomy with a body mass index (BMI) between 21 and 34 kg/m2. Herein, we detail the first United States experience with the Levita™ Magnetic Surgical System during laparoscopic cholecystectomy. METHODS: The Levita™ Magnetic Surgical System was used on consecutive patients undergoing laparoscopic cholecystectomy at our institution from June 2016 through November 2016. Only patients undergoing elective surgery and those with a body mass index (BMI) between 21 and 34 kg/m2 were included. Baseline patient characteristics, operative time, and perioperative details were collected. RESULTS: A total of ten patients underwent laparoscopic cholecystectomy with the Levita™ Magnetic Surgical System during the defined study period. The mean age at the time of surgery was 49.0 years and the average BMI of the cohort was 27.6 kg/m2. The average operative time was 64.4 min. There were no perioperative complications. Seven (70.0%) patients were discharged to home on the day of surgery, while the remaining three (30.0%) patients were discharged to home on postoperative day number one. Surgeons reported that the magnetic grasper was easy to use and provided adequate tissue retraction and exposure. CONCLUSIONS: The Levita™ Magnetic Surgical System is safe and feasible to use in patients undergoing laparoscopic cholecystectomy. Routine use of this system may facilitate a reduction in the total number of laparoscopic trocars used, leading to less tissue trauma and improved cosmesis. Additional studies are needed to determine the applicability and utility of this system for other general surgery cases.

INTRODUCTION: Enteral access through the jejunum is indicated when patients cannot tolerate oral intake or gastric feeding. While multiple approaches for feeding jejunal access exist, few studies have compared the efficacy of these techniques. The purpose of this study was to investigate the long-term durability, re-intervention rates, and nutritional outcomes following percutaneous endoscopic gastrostomy tubes with jejunal extension tubes (PEG-JET) versus laparoscopic jejunostomy tubes (j-tubes). METHODS: Retrospective chart review was performed on all patients who underwent PEG-JET or laparoscopic jejunostomy tube placement from January 2005 through December 2015 at our institution. Thirty-day and long-term outcomes were compared between the two groups. RESULTS: A total of 105 patients underwent PEG-JET and 307 patients underwent laparoscopic j-tube placement during the defined study period. In terms of 30-day outcomes, patients who underwent PEG-JET placement were significantly more likely to experience a tube dislodgement event (p = 0.005) and undergo a re-intervention (p < 0.001). Patients who had a laparoscopic j-tube placed were significantly more likely to meet their enteral feeding goals (p = 0.002) and less likely to require nutritional supplementation with total parenteral nutrition (TPN) (p < 0.001). With regard to long-term outcomes, patients who underwent PEG-JET placement were significantly more likely to experience tube occlusion (p < 0.001) and require an endoscopic or surgical tube re-intervention (p < 0.001). Patients who underwent laparoscopic j-tube placement were significantly more likely to experience a tube site leak (p = 0.015) but were less likely to require nutritional supplementation with TPN (p = 0.001). CONCLUSION: Laparoscopic jejunostomy tubes provide more durable long-term enteral access compared to PEG-JET. Consideration should be given to laparoscopic jejunostomy tube placement in eligible patients who cannot tolerate oral intake or gastric enteral feeding.

INTRODUCTION: Gastroparesis is a debilitating disease characterized by delayed gastric emptying in the absence of mechanical obstruction. A new intramural technique, per oral endoscopic pyloromyotomy (POP), has been proposed as an alternative to surgical pyloroplasty for the management of medical refractory gastroparesis. Herein, we detail the short-term results of POP at our institution. METHODS: POP was first performed at our institution in January 2016. All patients undergoing POP for management of gastroparesis from January 2016 through January 2017 were prospectively followed. All patients underwent a 4-h, non-extrapolated gastric emptying scintigraphy study and were asked to rate their symptoms using the Gastroparesis Cardinal Symptom Index (GCSI) at their pre-procedure visit and at 3 months post-procedure. RESULTS: A total of 47 patients underwent POP during the defined study period. Twenty-seven (57.4%) patients had idiopathic gastroparesis, 12 (25.6%) had diabetic gastroparesis, and eight (17.0%) had post-surgical gastroparesis. Forty-one (87.2%) patients had at least one previous intervention (i.e., enteral feeding tube, gastric pacer, botox injection) for their gastroparesis symptoms. All patients had evidence of gastroparesis on pre-procedure gastric emptying studies. The average length of hospital stay was 1 day. One patient died within 30-days of their index procedure which was unrelated to the procedure itself. The average pre-procedure percentage of retained food at 4 h was 37% compared to an average post-procedure percentage of 20% (p < 0.03). The average pre-procedure GCSI score was 4.6 compared to an average post-procedure GCSI of 3.3 (p < 0.001). CONCLUSIONS: POP is a safe and feasible endoscopic intervention for medical refractory gastroparesis. Additional follow-up is required to determine the long-term success of this approach in alleviating gastroparesis symptoms.

BACKGROUND: Readmission rate is an indicator of quality in surgical practice. We aimed to determine the predictors of unplanned early readmissions following stapling bariatric surgeries. METHODS: From the American College of Surgeons National Surgical Quality Improvement Program database, we identified morbidly obese patients, who underwent either laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y gastric bypass (LRYGB) in 2012 and 2013. Demographic, comorbidities, operative and postoperative parameters of the readmitted (within 30 days) and non-readmitted patients were evaluated using a multivariate logistic regression analysis. RESULTS: A total of 35,655 patients (17,101 LSG and 18,554 LRYGB) were analyzed. Of those, 1758 patients (4.9 %) were readmitted within 30 days of surgery. Multivariate analysis showed the following significant predictors for readmission: Non-Hispanic black ethnicity (OR: 1.56, 95 % CI:1.34-1.81), Hispanic ethnicity (OR: 1.29, 95 % CI:1.05-1.58), totally or partially dependent functional status (OR: 1.94, 95 % CI:1.06-3.55), higher preoperative creatinine (OR: 1.13, 95 % CI:1.04-1.22), lower serum albumin (OR: 0.78, 95 % CI:0.68-0.90), diabetes mellitus on insulin (OR: 1.28, 95 % CI:1.09-1.51), steroid or immunosuppressant use for a chronic condition (OR: 1.61, 95 % CI:1.11-2.33), history of cardiac disease with intervention (OR: 2.05, 95 % CI:1.10-3.83), bleeding disorders (OR: 1.71, 95 % CI:1.15-2.54), LRYGB versus LSG (OR: 1.63, 95 % CI:1.44-1.85), longer operative time (OR: 1.13, 95 % CI:1.07-1.20), concurrent splenectomy (OR: 4.10, 95 % CI:1.05-16.01), and occurrence of any postoperative complication during index admission (OR: 2.61, 95 % CI:1.99-3.42). CONCLUSIONS: Ethnicity, baseline functional status, comorbidities, type and duration of surgical procedure, and postoperative complications occurred in the index admission can predict risk of early readmission following LRYGB and LSG.

OBJECTIVE: Bariatric surgery (BS) is currently the most effective treatment for severe obesity. However, these weight loss procedures may result in the development of gut failure (GF) with the need for total parenteral nutrition (TPN). This retrospective study is the first to address the anatomic and functional spectrum of BS-associated GF with innovative surgical modalities to restore gut function. METHODS: Over 2 decades, 1500 adults with GF were referred with history of BS in 142 (9%). Of these, 131 (92%) were evaluated and received multidisciplinary care. GF was due to catastrophic gut loss (Type-I, 42%), technical complications (Type-II, 33%), and dysfunctional syndromes (Type-III, 25%). Primary bariatric procedures were malabsorptive (5%), restrictive (19%), and combined (76%). TPN duration ranged from 2 to 252 months. RESULTS: Restorative surgery was performed in 116 (89%) patients with utilization of visceral transplantation as a rescue therapy in 23 (20%). With a total of 317 surgical procedures, 198 (62%) were autologous reconstructions; 88 (44%) foregut, 100 (51%) midgut, and 10 (5%) hindgut. An interposition alimentary conduit was used in 7 (6%) patients. Reversal of BS was indicated in 84 (72%) and intestinal lengthening was required in 10 (9%). Cumulative patient survival was 96% at 1 year, 84% at 5 years, and 72% at 15 years. Nutritional autonomy was restored in 83% of current survivors with persistence or relapse of obesity in 23%. CONCLUSIONS: GF is a rare but serious life-threatening complication after BS. Successful outcome is achievable with comprehensive management, including reconstructive surgery and visceral transplantation.

BACKGROUND: Superior mesenteric artery syndrome (SMAS) is a disorder characterized by vascular compression of the duodenum leading to mechanical obstruction. Surgical intervention is indicated in patients who fail standard non-operative management, in which duodenojejunostomy is favored based on previous small series. Given the rarity of the condition, knowledge of the optimal indications for surgery, risk of postoperative complications, and prognosis of SMAS after minimally invasive duodenojejunostomy is limited. METHODS: A retrospective chart review was performed on patients who underwent minimally invasive duodenojejunostomy for SMAS from March 2005 to December 2013 at our "healthcare system". We analyzed patients' presentations, work-up, surgical therapy, and outcomes. RESULTS: A series of 14 patients with SMAS underwent minimally invasive duodenojejunostomy. All of these patients met clinical criteria of SMAS with radiological confirmation. Average weight loss before surgery was 10.7 kg. Depression and eating disorders were comorbid in 6/14 patients. The mean age was 39 years (19-91 years). Twelve operations were completed laparoscopically and two were performed with robotic assistance. Mean operation duration was 119 min and average length of hospital stay was 5.5 days. There were no immediate postoperative complications. One patient developed a delayed anastomotic stricture that improved with single endoscopic balloon dilation. Initial symptom improvement occurred in all patients and the improvement occurred in 11 patients (79%) during the follow-up. At a mean follow-up of 20 months, two patients experienced complications, including one infection at a simultaneously placed J-tube site and one patient with dumping syndrome. Mean weight gain was 3.8 kg (p < 0.01). CONCLUSION: SMAS should be considered a potential diagnosis in patients who present with a history of persistent postprandial vomiting, epigastric pain, and weight loss and confirmatory radiographic findings. In well-selected patients, minimally invasive duodenojejunostomy is a safe and effective treatment for SMAS with excellent short-term outcomes.

Background: Suboptimal weight loss (SWL) occurs up to 30% after sleeve gastrectomy (SG). Conversion to Roux-en-Y gastric bypass (cRYGB) has shown heterogeneous results in terms of additional weight loss and resolution of weight-related comorbidities. We aim to evaluate mid-term outcomes of cRYGB specifically for SWL after SG. Methods: All patients who underwent cRYGB for SWL from April 2010 to June 2019 from prospective registries at three affiliated tertiary care centers were retrospectively reviewed. Patients who underwent revision or conversion for complications were excluded. Mixed-effects and polynomial regression models were used to evaluate weight loss results after conversion. Results: Thirty-two patients underwent cRYGB from SG. About 68.7% were women with mean age of 46.6 years. Mean body mass index (BMI) before SG was 55.3 kg/m2. Before conversion, mean BMI was 44.5 kg/m2 with 17.3% total weight loss (TWL). All procedures were completed laparoscopically in a median surgical time of 183 min. Three major complications occurred (9.3%), one gastrojejunal (GJ) leak and two reoperations. Four cases (12.5%) of GJ stenosis were diagnosed. No mortality was registered. Mean follow-up time was 24 months and patients had 36 kg/m2 mean BMI, 17.4% TWL, 27.2% had BMI >35 kg/m2. Conclusions: cRYGB after SG for SWL showed good mid-term results, better than those reported in literature.
RESUMEN
BACKGROUND: One-anastomosis gastric bypass (OAGB), also known as minigastric bypass, is an increasingly popular bariatric surgery option worldwide. While OAGB offers advantage in terms of procedure time and technical ease, revisional operations to correct complications may be necessary. OBJECTIVES: We aimed to describe the indications and perioperative outcomes for OAGB conversions to Roux-en-Y gastric bypass (RYGB) at a single-referral center. SETTING: Academic hospital, Abu Dhabi, United Arab Emirates. METHODS: All patients undergoing conversion from OAGB to RYGB from February 2016 through September 2018 were retrospectively identified from a prospectively maintained database of revisional bariatric surgeries. RESULTS: Sixteen patients underwent conversion from previous OAGB to RYGB during the study period. The cohort was 62.5% female (n = 10) with a mean age of 40.2 years and median body mass index of 30.7 kg/m2. Indications for conversion included intractable nausea/vomiting (n = 8, 50.0%), biliary reflux (n = 3, 18.8%), weight recidivism (n = 3, 18.8%), and protein-calorie malnutrition (n = 2, 12.5%). Twelve cases (75.0%) were successfully completed with a laparoscopic approach, with 4 cases (25.0%) converted to open. The median length of stay was 5.5 days. Six patients (37.5%) experienced minor and major complications within 30 days of discharge. Fourteen patients (87.5%) were available for follow-up at 6 months, with 100% of these patients reporting resolution of their preoperative symptoms. There were no mortalities. CONCLUSIONS: Data from this largest reported single-center experience demonstrates that conversion of OAGB to RYGB is safe and technically feasible. Further studies and longer-term follow-up are needed to definitively describe outcomes after this revisional bariatric surgery.

BACKGROUND: Post-surgical gastroparesis (psGP) is putatively related to vagal denervation from either therapeutic transection or inadvertent injury. Here, we present a series of patients undergoing endoscopic per-oral pyloromyotomy (POP) as a treatment for medically refractory psGP. METHODS: Patients identified from a prospectively maintained database of patients undergoing POP procedures at our institution from January 2016 to January 2018 were included. Surgical history, symptom scores, and gastric emptying studies before and 3 months after POP were additionally recorded. RESULTS: During the study period, 177 POP procedures were performed, of which 38 (21.5%) were for psGP. The study cohort was 84.2% female with a mean body mass index of 27.6 kg/m2 and mean age of 55.2 years. Common comorbidities included hypertension (34.2%), depression (31.6%), and gastroesophageal reflux disease (28.9%). Hiatal/paraesophageal hernia repair (39.5%) or fundoplication (36.8%) preceded psGP diagnosis most often. The mean operative time was 30 ± 20 min. There were no intraoperative complications. Mean postoperative length of stay was 1.2 days. There were two readmissions within 30 days, one for melena and one for dehydration. The mean improvement in total Gastroparesis Symptom Index Score was 1.29 (p = 0.0002). The mean 4-h gastric retention improved from a pre-POP mean of 46.4 to 17.9% post-POP. Normal gastric emptying was noted in 50% of subjects with available follow-up imaging. CONCLUSION: POP is a safe and effective endoscopic therapy for patients with psGP. POP should be considered a reasonable first-line option for patients with medically refractory psGP and may allow stomach preservation.

BACKGROUND: With the worldwide epidemic of obesity, an increasing number of bariatric operations and antireflux fundoplications are being performed. Despite low morbidity of the primary foregut surgery, completion gastrectomy may be necessary as a definitive procedure for complications of prior foregut surgery; however, the literature evaluating outcomes after completion gastrectomy with esophagojejunostomy (EJ) for benign diseases is limited. We present our experience of completion gastrectomy with Roux-en-Y EJ in the setting of benign disease at a single tertiary center. METHODS AND PROCEDURES: All patients who underwent total, proximal, or completion gastrectomy with EJ for complications of benign foregut surgery from January 2006 to December 2015 were retrospectively identified. All cancer operations were excluded. RESULTS: There were 23 patients who underwent gastrectomy with EJ (13 laparoscopic EJ [LEJ] and 10 open EJ). The index operations included 12 antireflux, 9 bariatric, and 2 peptic ulcer disease surgeries. Seventy-eight percent of patients had surgical or endoscopic interventions before EJ, with a median of one prior intervention and a median interval from the index operation to EJ of 25 months (interquartile range 9-87). The 30-day perioperative complication rate was 30% with 17% classified being major (Clavien-Dindo ≥ III) and no 30-day perioperative mortality. Comparing laparoscopic and open approaches showed similar operative times, estimated blood loss, and overall complication rate. LEJ was associated with a shorter length of stay (LOS) (P < .001), fewer postoperative ICU days (P = .002), fewer 6-month complication rates (P < .007), and decreased readmission rate (P = .024). CONCLUSION: Our series demonstrates that EJ is a reasonable option for reoperative foregut surgery. The laparoscopic approach appears to be associated with decreased LOS and readmissions.

INTRODUCTION: A subset of patients undergoing laparoscopic sleeve gastrectomy (SG) require eventual conversion to Roux-en-Y gastric bypass (RYGB) due to complications from SG or to enhance weight loss. The aim of this study is to characterize the indications for conversion and perioperative outcomes in a large cohort of these patients at a single institution. METHODS: Patients who underwent revisional surgery to convert SG to RYGB at our institution from January 2008 through January 2017 were retrospectively reviewed. RESULTS: Eighty-nine patients with previous SG underwent conversion to RYGB as part of a planned two-stage approach to gastric bypass (n = 36), for weight recidivism (n = 11), or for complications related to SG (n = 42). Complications from SG that warranted conversion included refractory GERD (40.5%), sleeve stenosis (31.0%), gastrocutaneous (16.7%), or gastropleural (7.1%) fistula, and gastric torsion (4.1%). The mean (SD) age was 47.2 years (11.4 years) and median BMI at the time of revision was 43.2 kg/m2. A laparoscopic approach was successfully completed in 76 patients (85.4%), with an additional of four completed robotically (4.5%). The median length of stay was 3 days. Twenty-eight patients (31.5%) had complications which included surgical site infection (20.2%), re-operation (6.7%), anastomotic stricture (3.4%), and one pulmonary embolism. There were no mortalities with a median follow-up of 15 months. CONCLUSIONS: Conversion of SG to RYGB is safe and technically feasible when performed for complications of SG or to enhance weight loss. This operation can be successfully performed laparoscopically with a low rate of conversion and reasonable complication profile.

INTRODUCTION: In addition to increased perioperative morbidity, anastomotic leak following gastric resection for gastric cancer can have detrimental effects on overall and disease-free survival. The risk of anastomotic leak following neoadjuvant therapy remains unknown. The purpose of this study is to investigate the association of preoperative chemotherapy and radiation therapy with postoperative anastomotic leak and additional 30-day morbidity and mortality outcomes following total gastrectomy with reconstruction for gastric cancer using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). METHODS: Patients who underwent total gastrectomy with reconstruction for gastric cancer from 2005 to 2012 were identified. Within the NSQIP database, anastomotic leak is captured as an organ space infection. The association of preoperative chemotherapy and radiation therapy with anastomotic leak and additional 30-day morbidity and mortality outcomes was investigated using chi-squared analysis, Fisher's exact test, and Student's t test. RESULTS: A total of 1135 patients met inclusion criteria; 121 (10.7%) patients underwent preoperative chemotherapy within 30 days of surgery, and 53 (4.7%) patients underwent preoperative radiation therapy within 90 days of surgery. Neither preoperative chemotherapy nor radiation therapy was associated with an increased risk of anastomotic leak (p = 0.12 and p = 0.58, respectively). When compared to patients who did not undergo neoadjuvant therapy, patients who underwent either preoperative chemotherapy or radiation therapy did not experience a higher frequency of 30-day mortality (p = 0.41), cardiac (p = 0.49), wound (p = 0.76), renal (p = 0.13), septic (p = 0.55), or venous thromboembolism (p = 0.19) events and were significantly less likely to experience a pulmonary event (p = 0.02). CONCLUSION: Neoadjuvant therapy prior to gastric resection for gastric cancer is not associated with an increased risk of anastomotic leak or other additional short-term morbidity or mortality.

BACKGROUND: This series of patients with a history of Roux-en-Y gastric bypass (RYGB) and cholecystectomy presented with symptoms consistent with obstructive biliary disease and massive biliary dilation of ≥15 mm, suggesting a structural cause. Findings from laparoscopic-assisted transgastric (TG) ERCP were a normal-appearing ampulla without structural lesions or stones, suggesting a functional cause instead. STUDY DESIGN: Patients who underwent TGERCP from January 2008 to October 2016 and had a surgical history of RYGB and cholecystectomy were identified from an institutional database. Inclusion criteria was biliary dilation ≥15 mm, age 18 years or older, and no explanatory obstructive pathology. RESULTS: Nine female patients met the inclusion criteria. At time of TGERCP, their mean age was 53.9 years, mean BMI was 32.5 kg/m2, mean bile duct diameter was 18.1 mm, and all patients experienced abdominal pain. Six patients (66.7%) presented with abnormal liver enzymes, 5 (55.6%) with nausea and/or vomiting, and 4 (44.4%) with earlier episode(s) of acute pancreatitis. Each patient had a normal-appearing papilla of Vater without stones or strictures at the time of TGERCP, with 8 (88.9%) patients experiencing cessation of abdominal pain after biliary sphincterotomy. CONCLUSIONS: This cohort of patients with a history of RYGB and cholecystectomy presented with massively dilated biliary trees lacking an obstructive disease process and experienced immediate symptom improvement after sphincterotomy. Their surgical history predisposed them to vagal nerve injury, leading to denervation of the sphincter of Oddi, and resulting in tonic contraction of the ampulla, that is, ampullary achalasia.

INTRODUCTION: Patients with prior foregut surgery requiring long-term enteral access typically undergo operative jejunostomy tube placement; however, direct percutaneous endoscopic jejunostomy (DPEJ) is a viable alternative. METHODS: All de novo DPEJ procedures performed by surgical and advanced endoscopists from May 2003 to June 2015 were retrospectively reviewed following approval by the Institutional Review Board. There were 59 cases identified. RESULTS: Our cohort had a mean age of 50.3 ± 16.9 years and 35 (59.3%) were female. All but two patients previously had foregut surgery including 19 patients (34.5%) with prior bariatric surgery. The composite of malnutrition and dehydration was the indication for DPEJ in 29 patients (49.1%) and was the initial enteral access placed in 47 patients (79.7%). Moderate sedation was used in 32 cases (54.2%), and 29 procedures (49.2%) were performed in the operating room. Within 30 days, there were six complications in five patients, giving a peri-procedural complication rate of 12.5%. Beyond 30 days, the most common complications were peri-tube leakage and dislodgement (each 16.9%). The median time to complication was 197 days. CONCLUSIONS: In patients with surgically altered foregut anatomy, DPEJ offers a less invasive alternative to operative jejunostomy tube placement. DPEJ can be placed in the endoscopy suite or operating room with an acceptable risk of perioperative complications.

BACKGROUND: Obesity and rapid weight loss are risk factors for gallstone development. Bariatric surgery and significant postoperative weight loss are associated with postoperative biliary complications. OBJECTIVE: We aim to identify predictive factors of biliary complications after bariatric surgery. SETTING: University hospital. METHODS: After Institutional Review Board approval, charts at a single institution were reviewed to identify patients with biliary complications after bariatric surgery from 2005 to 2012. Data collected included baseline patients demographic characteristics, perioperative parameters, and postoperative biliary complications. Parameters were analyzed using paired and unpaired Student t test for continuous variables and χ2 test for categorical variables. Univariate and multivariate analyses were used to assess risk factors for complications after bariatric surgery. All tests were 2 tailed; results with P<.05 were considered statistically significant. RESULTS: One hundred thirty-eight (3.6%) of 3765 patients who underwent bariatric surgery developed postoperative biliary complications. Mean time from surgery to biliary complication was 1.8±1.4 years. Complications included acute cholecystitis (18.1%), chronic cholecystitis (70.2%), acute pancreatitis (9.4%), choledocholithiasis (5.7%), and jaundice (2.8%). Interventions were laparoscopic (n = 134, 97.0%) and open (n = 1, .7%) cholecystectomy. Forty patients (28.9%) had known cholelithiasis before surgery. There were no mortalities. Univariate analysis identified female gender, age>50, cholelithiasis at time of bariatric procedure, and Roux-en-Y gastric bypass independent of excess weight loss as predictive factors of biliary complications. Multivariate analysis confirmed advanced age as an independent predictive factor. CONCLUSION: The results of our study suggest that patients of advanced age are at higher risk of biliary complications. However, the indications for prophylactic cholecystectomy at time of bariatric surgery remain unclear.

BACKGROUND: Anastomotic complications after foregut surgery include leaks, fistulas, and late strictures. The management of these complications can be challenging, and it may be desirable to avoid complex reoperation. OBJECTIVES: We aim to describe the indications and outcomes of the use of esophageal self-expanding metal stents in the management of postoperative anastomotic complications after foregut surgery. SETTING: Tertiary-referral academic medical center. METHODS: We performed a retrospective review of a prospectively managed database. Data was collected on patient demographic characteristics, work-up, intraprocedure findings, and outcomes. RESULTS: From October of 2009 to November of 2014, 47 patients (mean age 51.1, 36 women and 11 men) underwent endoscopic stent placement for anastomotic complications following upper gastrointestinal (UGI) surgery. The median time from index operation to endoscopic stent placement was 52 days (range 1-5280 days). Indications were sleeve leak or stenosis, gastrojejunal leak or stenosis after Roux-en-Y gastric bypass (RYGB), pouch staple-line leak after RYGB, enterocutaneous fistula, perforation after endoscopic dilation, upper gastrointestinal bleeding after peroral endoscopic myotomy (POEM), and peptic stricture after POEM. Symptomatic improvement occurred in 76.6% of patients, and early oral intake was initiated in 66% of patients. 14 patients (29.8%) went on to require definitive surgical intervention for persistent symptomatology. The average follow-up was 354.1 days (range 25-1912 days). CONCLUSION: This paper describes the use of endoscopic stent therapy for a variety of pathologies after upper gastrointestinal surgery. We demonstrate that, in the appropriate setting, it is an effective and less-invasive therapeutic approach.
