Endoscopic retrograde cholangiopancreatography versus endoscopic ultrasound for tissue diagnosis of malignant biliary stricture: Systematic review and meta-analysis. Endosc Ultrasound 2018; 7:10-19. [PMID: 27824027 PMCID: PMC5838722 DOI: 10.4103/2303-9027.193597] [Citation(s) in RCA: 87] [Impact Index Per Article: 12.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2015] [Accepted: 07/05/2015] [Indexed: 12/14/2022] [Imported: 08/29/2023] Open
Abstract
BACKGROUND AND AIMS There are no systematic reviews comparing the use of endoscopic retrograde cholangiopancreatography (ERCP)-based brush cytology and forceps biopsy and endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) for the diagnosis of malignant biliary stricture; so in this revision, we will compare ERCP against EUS-FNA for tissue diagnosis of malignant biliary stricture. DESIGN A systematic review was conducted of comparative studies (prospective or retrospective) analyzing EUS and ERCP for tissue diagnosis of malignant biliary stricture. MATERIALS AND METHODS The databases Medline, EMBASE, Cochrane, LILACS, CINAHL, and Scopus were searched for studies dated previous to November 2014. We identified three prospective studies comparing EUS-FNA and ERCP for the diagnosis of malignant biliary stricture and five prospective studies comparing EUS-FNA with the same diagnosis of the other three studies. All patients were subjected to the same gold standard method. We calculated study variables (sensitivity, specificity, prevalence, positive and negative predictive values, and accuracy) and performed a meta-analysis using the Review Manager (RevMan) 5.3 software. RESULTS A total of 294 patients were included in the analysis. The pretest probability for malignant biliary stricture was 76.66%. The mean sensitivities of ERCP and EUS-FNA for tissue diagnosis of malignant biliary stricture were 49% and 75%, respectively; the specificities were 96.33% and 100%, respectively. The posttest probabilities positive predictive value (98.33% and 100%, respectively) and negative predictive value (34% and 47%, respectively) were determined. The accuracies were 60.66% and 79%, respectively. CONCLUSION We found that EUS-FNA was superior to ERCP with brush cytology and forceps biopsy for diagnosing malignant biliary strictures. However, a negative EUS-FNA or ERCP test may not exclude malignant biliary stricture because both have low negative posttest probabilities.

Abstract
A gastrointestinal (GI) transmural defect is defined as total rupture of the GI wall, and these defects can be divided into three categories: perforations, leaks, and fistulas. Surgical management of these defects is usually challenging and may be associated with high morbidity and mortality rates. Recently, several novel endoscopic techniques have been developed, and endoscopy has become a first-line approach for therapy of these conditions. The use of endoscopic vacuum therapy (EVT) is increasing with favorable results. This technique involves endoscopic placement of a sponge connected to a nasogastric tube into the defect cavity or lumen. This promotes healing via five mechanisms, including macrodeformation, microdeformation, changes in perfusion, exudate control, and bacterial clearance, which is similar to the mechanisms in which skin wounds are treated with commonly employed wound vacuums. EVT can be used in the upper GI tract, small bowel, biliopancreatic regions, and lower GI tract, with variable success rates and a satisfactory safety profile. In this article, we review and discuss the mechanism of action, materials, techniques, efficacy, and safety of EVT in the management of patients with GI transmural defects.

Abstract
BACKGROUND Obesity has become a worldwide epidemic, and many methods are currently used to reduce obesity. This systematic review shows the effectiveness of the intragastric balloon (IGB) method compared to the sham/diet (s/d) method. OBJECTIVE To demonstrate the effectiveness of the IGB method compared to the s/d method. SETTING Hospital das Clinicas da Universidade de São Paulo, Brazil, Public Hospital. METHODS After searching MEDLINE, Embase, Cochrane, Lilacs, Scopus, and CINAHL, only enrolled randomized control trials comparing IGB/diet with s/d were analyzed. For qualitative analysis, 12 studies were selected, and 9 of these were acceptable for quantitative analysis. RESULTS The IGB/diet is more effective than s/d when comparing body mass index (BMI) loss with a mean difference of 1.1 kg/m(2) by the Student's t test and 1.41 kg/m(2) by the meta-analysis, with significant differences in both. It is also more effective in weight loss (WL), with a mean difference of 2 kg by the Student's t test and 3.55 kg by the meta-analysis. In the qualitative analysis of % excess WL (%EWL), the mean %EWL is 14.0% in favor of the IGB group compared to the s/d group by the Student's t test; however, no significant difference was found between these groups by quantitative analysis. CONCLUSION Based on randomized control trial data alone, IGB>400 mL is more effective than sham/diet in achieving BMI loss, WL, and %EWL.

Abstract
BACKGROUND Sleeve gastrectomy is a well-standardized surgical treatment for obesity. However, rates of weight regain after sleeve gastrectomy in long-term follow-up are relatively high. This multicenter study is the first to evaluate the use of an endoscopic sleeve gastroplasty (ESG) technique for the management of this population. METHODS This was a multicenter retrospective study, including patients with weight regain following sleeve gastrectomy who underwent ESG for weight loss. Primary outcomes included absolute weight loss, percent total weight loss (%TWL), change in body mass index (BMI), percent excess weight loss (%EWL) at 6 and 12 months, and safety profile. Clinical success was defined as achieving ≥ 25 % EWL at 1 year, ≤ 5 % serious adverse event (SAE) rate following society-recommended thresholds, and %TWL ≥ 10 %. RESULTS 34 patients underwent ESG after sleeve gastrectomy. Technical success was 100 %. At 1 year, 82.4 % and 100 % of patients achieved ≥ 10 %TWL and ≥ 25 % EWL, respectively. Mean (SD) %TWL was 13.2 % (3.9) and 18.3 % (5.5), and %EWL was 51.9 % (19.1) and 69.9 % (29.9) at 6 months and 1 year, respectively. Mean (SD) %TWL was 14.2 % (12.5), 19.3 % (5.3), 17.5 % (5.2), and 20.4 % (3.3), and %EWL was 88.5 % (52.8), 84.4 % (22.4), 55.4 % (14.8), and 47.8 % (11.2) for BMI categories of overweight and obesity class I, II, and III, respectively, at 1 year. No predictors of success were identified in the multivariable regression analysis. No SAEs were reported. CONCLUSION ESG appears to be safe and effective in the management of weight regain following sleeve gastrectomy.

Abstract
The most effective and durable treatment for obesity is bariatric surgery. However, less than 2% of eligible patients who fulfill the criteria for bariatric surgery undergo the procedure. As a result, there is a drive to develop less invasive therapies to combat obesity. Endoscopic bariatric therapies (EBT) for weight loss are important since they are more effective than pharmacological treatments and lifestyle changes and present lower adverse event rates compared to bariatric surgery. Endoscopic sleeve gastroplasty (ESG) is a minimally invasive EBT that involves remodeling of the greater curvature. ESG demonstrated favorable outcomes in several centers, with up to 20.9% total body weight loss and 60.4% excess weight loss (EWL) on 2-year follow-up, with a low rate of severe adverse events (SAE). As such, it could be considered safe and effective in light of ASGE/ASMBS thresholds of > 25% EWL and ≤ 5% SAE, although there are no comparative trials to support this. Additionally, ESG showed improvement in diabetes mellitus type 2, hypertension, and other obesity-related comorbidities. As this procedure continues to develop there are several areas that can be addressed to improve outcomes, including device improvements, technique standardization, patient selection, personalized medicine, combination therapies, and training standardization. In this editorial we discuss the origins of the ESG, current data, and future developments.

Abstract
Serologic testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) promises to assist in assessing exposure to and confirming the diagnosis of coronavirus disease 2019 (COVID-19), and to provide a roadmap for reopening countries worldwide. Considering this, a proper understanding of serologic-based diagnostic testing characteristics is critical. The aim of this study was to perform a structured systematic review and meta-analysis to evaluate the diagnostic characteristics of serological-based COVID-19 testing. Electronic searches were performed using Medline (PubMed), EMBASE, and Cochrane Library. Full-text observational studies that reported IgG or IgM diagnostic yield and used nucleic acid amplification tests (NAATs) of respiratory tract specimens, as a the reference standard in English language were included. A bivariate model was used to compute pooled sensitivity, specificity, positive/negative likelihood ratio (LR), diagnostic odds ratio (OR), and summary receiver operating characteristic curve (SROC) with corresponding 95% confidence intervals (CIs). Five studies (n=1,166 individual tests) met inclusion criteria. The pooled sensitivity, specificity, and diagnostic accuracy for IgG was 81% [(95% CI, 61-92);I2=95.28], 97% [(95% CI, 78-100);I2=97.80], and 93% (95% CI, 91-95), respectively. The sensitivity, specificity, and accuracy for IgM antibodies was 80% [(95% CI, 57-92);I2=94.63], 96% [(95% CI, 81-99);I2=92.96] and 95% (95% CI, 92-96). This meta-analysis demonstrates suboptimal sensitivity and specificity of serologic-based diagnostic testing for SARS-CoV-2 and suggests that antibody testing alone, in its current form, is unlikely to be an adequate solution to the difficulties posed by COVID-19 and in guiding future policy decisions regarding social distancing and reopening of the economy worldwide.

Abstract
Treating gastrointestinal (GI) fistulas endoscopically is challenging owing to an established epithelial tract. The variety of endoscopic approaches is transforming endoscopy into a first-line therapy. However, many sessions are often required, with variable success rates. Owing to these limitations, the off-label use of cardiac septal occluders (CSOs) has been reported. We searched for articles related to CSOs in the MEDLINE, EMBASE, Cochrane Library, and LILACS databases and gray literature. The primary outcomes included technical success, clinical success, and safety of CSOs in GI fistula management. A total of 25,574 records were identified, and 19 studies ultimately satisfied the inclusion criteria. Technical success was achieved in all cases. Of the 22 fistulas, 77.27% had successful closure, with a mean follow-up period of 32.02 weeks. The adverse event rate was 22.72%, with no associated mortality. Univariable and multivariable regression analyses showed no significant difference in the success of closure and adverse events in relation to several variables among the subgroups. The use of CSOs appeared to be technically feasible, effective, and safe in the treatment of GI fistulas. The satisfactory results derived from this sparse literature suggest that it can be an option in the management of GI fistulas.

Abstract
BACKGROUND The management of laparoscopic sleeve gastrectomy leaks remains a challenge. This can be treated with placement of self-expandable metal stents, which are most effective in the acute and early settings. However, migration is a frequent adverse event (AE). Novel, fully covered stents with a larger proximal flare to limit migration designed specifically to treat postsleeve leaks were recently introduced. OBJECTIVES The aim of this study was to evaluate the safety and efficacy of a novel stent specifically designed for postsleeve leaks treatment. SETTING Multicenter retrospective study. METHODS This is a multicenter study, including patients with acute and early post laparoscopic sleeve gastrectomy leaks, treated with a large bariatric stent. The outcomes include technical success, clinical success, and safety profile. A multivariable regression was performed to assess predictors of success. RESULTS Thirty-seven patients were included (10 acute and 27 early leaks), with 30 stents in the postpyloric (POST) and 7 in the prepyloric position. Technical success was 100%. Mean stent dwell time was 29.08 days. Clinical success was achieved in 78.37%. Leak duration, leak size, and stent dwell time did not correlate with clinical success. During follow-up, 8 patients had stent migration (21.62%) and all were in a POST position. AE poststent removal were also evaluated (prepyloric: 57.14% vs POST: 33.3%, P = .45). There was no difference between prepyloric and POST position in the severe AE analysis. CONCLUSIONS This novel, large-caliber, fully covered stent specifically designed for sleeve leaks appears to be effective at treating acute and early leaks. However, the large flanges and long stent length do not appear to reduce migration rate and may be associated with higher overall severe AE rates. Avoiding placement in the POST position may help mitigate migration risk; however, owing to the risk profile this stent should be used with caution.

Pancreatic metastases from ocular malignant melanoma: the use of endoscopic ultrasound-guided fine-needle aspiration to establish a definitive cytologic diagnosis: a case report. J Med Case Rep 2016; 10:332. [PMID: 27906105 PMCID: PMC5134225 DOI: 10.1186/s13256-016-1121-2] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2016] [Accepted: 10/24/2016] [Indexed: 12/12/2022] [Imported: 08/29/2023] Open
Abstract
BACKGROUND When encountering solid pancreatic lesions, nonpancreatic primary metastases are rare and differentiating a metastasis from a primary neoplastic lesion is challenging. The clinical presentation and radiologic features can be similar and the possibility of a pancreatic metastasis should be considered when the patient refers to a history of a different primary cancer. Endoscopic ultrasound offers a key anatomical advantage in accessing the pancreas and endoscopic ultrasound-guided fine-needle aspiration has become the gold standard method for diagnosing pancreatic lesions. CASE PRESENTATION A 58-year-old white Hispanic woman with a history of uveal malignant melanoma, presented with abdominal pain and jaundice. On admission, laboratory tests were performed (her total bilirubin was 6.37 mg/dL with a direct fraction of 5.30 mg/dL). Cross-sectional, abdominal computed tomography with contrast, showed a low-attenuating lesion localized in the pancreatic head (measuring 4 × 3 cm) and a thinner section of the distal bile duct suspicious for compression. Our patient was scheduled for an endoscopic ultrasound-guided fine-needle aspiration to establish a diagnosis. Endoscopic ultrasound showed a solid, hypoechoic, well-defined lesion with regular contours (measuring 3.17 × 2.61 cm), localized between the head and neck of the pancreas. Endoscopic ultrasound-guided fine-needle aspiration was performed with a 22G needle and cytology confirmed the diagnosis of metastatic melanoma. Our patient subsequently underwent right orbital exenteration, followed by duodenopancreatectomy without complications. At the moment our patient is receiving adjuvant chemotherapy at an outside oncology clinic. CONCLUSIONS To the best of our knowledge, this is a very rare presentation of an ocular malignant melanoma with an isolated pancreatic metastasis causing symptomatic biliary obstruction. Endoscopic ultrasound-guided fine-needle aspiration has proven to be the best method to diagnose solid pancreatic lesions. In this particular case, cytology was essential in confirming the diagnosis and guiding the most adequate therapy, which was a pancreatic resection, ocular exenteration of the melanoma, followed by adjuvant chemotherapy.

Abstract
OBJECTIVES Brazil has rapidly developed the second-highest number of COVID-19 cases in the world. As such, proper symptom identification, including gastrointestinal manifestations, and relationship to health outcomes remains key. We aimed to assess the prevalence and impact of gastrointestinal symptoms associated with COVID-19 in a large quaternary referral center in South America. METHODS This was a single-center cohort study in a COVID-19 specific hospital in São Paulo, Brazil. Consecutive adult patients with laboratory confirmed SARS-CoV-2 were included. Baseline patient history, presenting symptoms, laboratory results, and clinically relevant outcomes were recorded. Regression analyses were performed to determine significant predictors of the gastrointestinal manifestations of COVID-19 and hospitalization outcomes. RESULTS Four-hundred patients with COVID-19 were included. Of these, 33.25% of patients reported ≥1 gastrointestinal symptom. Diarrhea was the most common gastrointestinal symptom (17.25%). Patients with gastrointestinal symptoms had higher rates of concomitant constitutional symptoms, notably fatigue and myalgia (p<0.05). Gastrointestinal symptoms were also more prevalent among patients on chronic immunosuppressants, ACE/ARB medications, and patient with chronic kidney disease (p<0.05). Laboratory results, length of hospitalization, ICU admission, ICU length of stay, need for mechanical ventilation, vasopressor support, and in-hospital mortality did not differ based upon gastrointestinal symptoms (p>0.05). Regression analyses showed older age [OR 1.04 (95% CI, 1.02-1.06)], male gender [OR 1.94 (95% CI, 1.12-3.36)], and immunosuppression [OR 2.60 (95% CI, 1.20-5.63)], were associated with increased mortality. CONCLUSION Based upon this Brazilian study, gastrointestinal manifestations of COVID-19 are common but do not appear to impact clinically relevant hospitalization outcomes including the need for ICU admission, mechanical ventilation, or mortality.

Abstract
INTRODUCTION With the cumulative increase in the number of patients undergoing bariatric surgery, postoperative weight regain has become a considerable challenge. Mechanisms for weight regain are not fully understood and the process is likely multifactorial in many cases. Endoluminal revisions that reduce gastric pouch size and diameter of the gastrojejunal anastomosis may offer an effective and less invasive management strategy for this population. AREAS COVERED We critically review data from case series, retrospective and prospective studies, and meta-analyses pertaining to weight regain after gastric bypass. A variety of endoscopic revision approaches are reviewed, including technique details, procedural safety and efficacy, and post-procedure care. EXPERT COMMENTARY Given the proliferation of endoluminal therapies with evidence showing safety and efficacy in the treatment of weight regain, it is likely that endoscopic revision will be the gold standard to treat weight regain in patients with gastric bypass.

The importance of endoscopic ultrasound fine-needle aspiration in the diagnosis of solid pseudopapillary tumor of the pancreas: two case reports. J Med Case Rep 2018; 12:107. [PMID: 29695287 PMCID: PMC5918898 DOI: 10.1186/s13256-018-1585-3] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2017] [Accepted: 01/27/2018] [Indexed: 12/26/2022] [Imported: 08/29/2023] Open
Abstract
BACKGROUND Solid pseudopapillary tumor of the pancreas, otherwise known as solid and cystic tumor or Frantz tumor, is an unusual form of pancreatic carcinoma, with unknown etiopathogenesis, that accounts for 0.2 to 2.7% of all pancreatic tumors. It is defined as an exocrine pancreatic neoplasia that mainly affects women between the second and third decade of life, and its management is not well defined. Endoscopic ultrasound offers a key anatomical advantage in accessing the pancreas and endoscopic ultrasound fine-needle aspiration has become the gold standard method for the diagnosis of pancreatic lesions. CASE PRESENTATION Case 1: A 31-year-old white Hispanic woman presented with epigastric pain for 5 months. An abdominal ultrasound revealed a single 2 cm nodule in the uncinate process of her pancreas. Endoscopic ultrasound showed a regular, well-defined solid lesion with alternating cystic areas at the uncinate process of her pancreas, measuring 1.7 × 1.4 cm; endoscopic ultrasound fine-needle aspiration was then performed with cytopathological analysis compatible with solid pseudopapillary tumor. Body computed tomography confirmed the absence of metastases and she underwent conventional duodenopancreatectomy. However, she died 4 days after surgery due to postoperative surgical complications. Case 2: A 35-year-old Hispanic woman presented with left upper quadrant abdominal pain for 3 months, associated with a palpable mass at this region. A computed tomography scan showed a solitary nodule in the pancreatic body. Endoscopic ultrasound showed a regular, well-defined, homogeneous lesion with small anechoic (cystic) areas, measuring 2 × 2 cm, in between the pancreatic body and neck. Endoscopic ultrasound fine-needle aspiration was performed and cytopathological analysis was suggestive of a pseudopapillary solid tumor. She underwent a body-tail laparoscopic pancreatectomy with splenectomy. Nine months after the diagnosis, she remains asymptomatic, continuing regular follow-up in the oncology out-patient clinic. CONCLUSIONS Solid pseudopapillary tumor is a rare pancreatic malignancy. Endoscopic ultrasound fine-needle aspiration is the gold standard method to characterize and diagnose this type of pancreatic lesion, making this an invaluable tool to help guide clinical management and improve the preoperative diagnostic yield.

Abstract
Video 1Cost-effective modified endoscopic vacuum therapy for GI transmural defects. Step-by-step process of manufacturing and potential advantages.1.Cut half gauze to the ideal size to cover only the fenestrated portion of the nasogastric tube (NGT).2.Wrap the gauze around the fenestrated portion of the NGT. The assistance of another person is important in this process.3.Cut the antimicrobial incise drape to match the size of the fenestrated portion of the NGT. Note that the incise drape is a very strong adhesive; therefore, 3 people are usually required to assemble it properly.4.Next, the suture is used to fix the gauze and drape to the NGT. Perform fixation of the modified sponge in 3 places. The first knot is in the proximal portion, just below the last fenestra of the NGT, as a marker of where the vacuum system starts. The second knot is at the distal end, to avoid migration of the modified sponge. The third knot is in the middle of the modified sponge, which is essential to serve as a guide during endoscopic placement. For example, in cases of defects without collection in which the sponge will be placed in an intraluminal position, it is ideal to place the vacuum system in the middle of the defect; in cases of intracavitary placement, it will work as a guide to how much of the modified sponge will be inside the collection.5.Finally, use a needle to make innumerable punctures in the modified sponge system to obtain adequate aspiration. An 18G needle is recommended because, in addition to having an adequate diameter, it is very sharp, which facilitates perforation of the modified sponge system.6.After creation of the modified endoscopic vacuum therapy, the functionality test is performed. Turn on the wall suction system, connect the distal end of the NGT to the tube of the canister connected on the wall, and place the NGT inside a bowl with a liquid solution. The aspiration of a large amount of liquid indicates proper functioning of the modified endoscopic vacuum therapy system.7.The device is then ready to be positioned endoscopically in the patient. After proper positioning, connect the NGT to the suction tube to avoid migration of the device upon removal of the scope.8.In addition to the cost-effective device as described, in our practice we also use wall suction to reduce costs associated with the use of the vacuum machine.9.Use the antimicrobial incise drape to seal the connection between the NGT and the suction tube to avoid leakage within the connection.10.Last, owing to instability of the negative wall pressure, a 20F intravenous catheter is connected to the tube to maintain a negative pressure between -75 and -150 mmHg, as confirmed by laboratory studies performed by our group.

Abstract
BACKGROUND Obesity is a chronic and multifactorial disease with a variety of potential treatment options available. Currently, there are several multidisciplinary therapeutic options for its management, including conservative, endoscopic, and surgical treatment. AIM To clarify indications, technical aspects, and outcomes of bariatric endoscopy. METHODS Narrative review of current literature based on electronic databases including MEDLINE (PubMed), Cochrane Library, and SciELO. RESULTS Bariatric endoscopy is in constant development and comprises primary and revisional treatment options as well as management of surgical complications. Various devices act upon different mechanisms of action, which may be individualized to each patient. Despite favorable results for the endoscopic treatment of obesity, prospective randomized studies with long-term follow-up are required to fully validate primary and revisional endoscopic therapies. Regarding the management of bariatric surgery complications, endoscopic therapy may be considered the procedure of choice in a variety of situations. Still, as there is no standardized algorithm, local experience should be considered in decision-making. CONCLUSION The treatment of patients with obesity is complex, and a multidisciplinary approach is essential. Bariatric endoscopy has shown impressive results both in the treatment of obesity and its surgical complications, and therefore, must be part of the armamentarium in the fight against this disease.

Abstract
PURPOSE Closure of GG fistulas after RYGB is challenging due to epithelialization of the tract. Common endoscopic therapies are less efficacious than surgical revision, which is unfortunately fraught with high morbidity and mortality. Cardiac septal defect occluders (CSDO) have been successfully used for the management of gastrointestinal fistulas, but use has never been reported in management of GG fistulas. Thus, we describe the first off-label use of CSDO for the treatment of a GG fistula. MATERIALS AND METHODS Endoscopy and fluoroscopic examination determined the appropriate size of CSDO for closure. A guidewire was placed in the remnant stomach followed by placement of the delivery system. Then, under fluoroscopy, we deployed the first flange of the CSDO in the remnant stomach. Then, under fluoroscopy and endoscopic visualization, the second flange is deployed in the gastric pouch. RESULTS A 51-year-old woman, status-post RYGB in 2008, presented with a 6-month history of weight regain and reflux. She had regained weight to 84 kg (BMI = 32 kg/m2) when she was found to have a GG fistula. She underwent successful CSDO placement and, 3 months later, had lost 10 kg with significant improvement in her reflux. Repeat evaluation confirmed successful fistula closure. CONCLUSION The use of CSDO was technically feasible and appeared to be effective and safe. Future studies should continue to investigate the role of CSDO in management of this challenging condition.

Abstract
BACKGROUND Mechanisms for weight regain after gastric bypass are not fully understood and the process is likely multifactorial. The initial step in the management of weight regain is a comprehensive evaluation of contributing factors. While lifestyle modification is fundamental, it has limited efficacy which can be enhanced by medications and/or endoscopic revision. Anatomic changes such as larger pouch size and dilation of the gastrojejunal anastomosis (GJA) may contribute to increased postoperative weight gain. Endoluminal revisions offer an effective and less invasive management strategy for this population. METHODS A 55-year-old female with history of RYGB in 2006 presented with weight regain. She was referred to our unit for endoscopic evaluation. RESULTS During endoscopy, a large GJA (25 mm in diameter) was diagnosed. A novel trans-oral outlet reduction (TORe) was then performed. A modified ESD was first performed on the GJA, followed by argon plasma coagulation of the margins of the ESD. Then a purse-string TORe with suturing was performed, using a 10 mm balloon to size the GJA. On 6-month follow-up, patient lost 20 lb. and 12.26 %TBWL and EGD showed a 10 mm diameter GJA. On 1-year follow-up, patient weight loss was 14 lb. and 8.58 %TBWL. The follow-up endoscopy showed a 12 mm diameter GJA. CONCLUSION Endoluminal therapies are safe, reproducible, and effective in the treatment of weight regain and should be utilized as a first-line approach to manage this condition. This novel-combined approach is feasible and may be more effective in the treatment of weight regain.
