Abstract
INTRODUCTION Gastric sleeve stenosis (GSS) is an increasingly common adverse event following sleeve gastrectomy for which objective diagnostic criteria are lacking. Impedance planimetry measurements show promise in characterizing GSS, though normal and abnormal benchmark values have never been established. METHODS This was a retrospective analysis of upper endoscopies performed with impedance planimetry for suspected GSS. A bariatric endoscopist, blind to impedance planimetry measurements, assessed gastric sleeve anatomy and graded GSS severity. Impedance planimetry of diameter and distensibility index (DI) were obtained using 3 different balloon volumes (30, 40, and 50 mL). RESULTS A total of 110 upper endoscopies were included. Distribution of GSS was graded as none, mild, moderate, and severe in 19 (17%), 27 (25%), 34 (31%), and 30 (27%) procedures, respectively. In normal gastric sleeve anatomy, mean (±SD) diameter and DI measurements using consecutive balloon volumes ranged from 19.1 (±5.5) to 23.2 (±1.7) and 16.8 (±4.9) to 23.1 (±10.9), respectively. In severe GSS, mean diameter and DI measurements ranged from 10.3 (±3.0) to 16.6 (±2.1) and 7.5 (±2.4) to 7.7 (±2.4), respectively. When stratified by severity, impedance planimetry measurements of diameter and DI were significantly lower with each subsequent increase in GSS grade regardless of balloon fill volumes ( P ≤ 0.001). DISCUSSION Impedance planimetry measurements provide objective assessment in the diagnosis of GSS and correlate with luminal narrowing. A diameter ≥20 mm and a DI ≥15 mm 2 /mm Hg, as measured by impedance planimetry, are predictive of normal gastric sleeve anatomy. This study provides new benchmark values for the diagnosis and severity of GSS.

Abstract
Obesity is associated with several chronic conditions including diabetes, cardiovascular disease, and metabolic dysfunction-associated steatotic liver disease and malignancy. Bariatric surgery, most commonly Roux-en-Y gastric bypass and sleeve gastrectomy, is an effective treatment modality for obesity and can improve associated comorbidities. Over the last 20 years, there has been an increase in the rate of bariatric surgeries associated with the growing obesity epidemic. Sleeve gastrectomy is the most widely performed bariatric surgery currently, and while it serves as a durable option for some patients, it is important to note that several complications, including sleeve leak, stenosis, chronic fistula, gastrointestinal hemorrhage, and gastroesophageal reflux disease, may occur. Endoscopic methods to manage post-sleeve gastrectomy complications are often considered due to the risks associated with a reoperation, and endoscopy plays a significant role in the diagnosis and management of post-sleeve gastrectomy complications. We perform a detailed review of the current endoscopic management of post-sleeve gastrectomy complications.

Abstract
INTRODUCTION Despite the increasing number of bariatric procedures over the recent years, the physiological changes in secondary esophageal motility and distensibility parameters after surgery remain unknown. METHODS This is a retrospective, single-center cohort study comparing esophageal planimetry and gastroesophageal junction (GEJ) distensibility in post-bariatric surgery patients (Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and conversion/revisional patients (DH)) and native-anatomy patients with obesity (NAC). Distensibility refers to the area achieved with a certain amount of pressure, and secondary peristalsis represents the esophageal response to an intended obstruction. Patients with pre-surgical dysmotility symptoms were excluded from the study. RESULTS From November 2018 to January 2023, 167 patients were evaluated and eligible for this study (RYGB = 87, SG = 33, NAC = 22, DH = 25). In NAC cohort, 17/22 (77%) patients presented normal motility patterns compared to 35/87 (40%) RYGB, 12/33 (36%) SG, and 5/25 (20%) DH (p < 0.05 for all comparisons). The most common abnormal motility pattern for all three bariatric cohorts was absent contractions. DH patients generally had the highest mean maximum distensibility index averages, followed by SG, RYGB, and NAC. CONCLUSION Bariatric surgery affects esophageal and GEJ physiology, and it is associated with higher rates of secondary dysmotility. DH patients have even higher rates of dysmotility. Further studies assessing clinical data and their correlation with manometric and pH-metric findings are needed.

Abstract
PURPOSE OF REVIEW The prevalence of childhood and adolescent obesity in the United States has reached alarming levels, necessitating effective interventions such as bariatric surgery. This article reviews the current state of bariatric surgery in the adolescent population, highlighting the common complications encountered in post-bariatric patients. Furthermore, it outlines the pivotal role of endoscopy in both the prevention and management of these bariatric complications. RECENT FINDINGS Though only a minority of eligible adolescent patients undergo bariatric surgery the number of cases continues to increase. Sleeve gastrectomy has emerged as the preferred type of surgery, with the best balance of safety and efficacy. However, only a small number of pediatric surgeons have additional bariatric training and a number of technical aspects of the surgery itself impact the risk for post-surgical complications. Gastric sleeve stenosis, anastomotic leaks and gastroesophageal reflux are the most common of these complications. Ability to perform dilation of sleeve stenosis, closure of anastomotic leaks and evaluation of reflux are critical tools in the endoscopic toolbox necessary for the management of these complicated patients. Bariatric surgery remains the most effective treatment available for management of morbid obesity in adolescents but has significant associated complications. Pediatric gastroenterologists must be familiar in the endoscopic management of these complications and are crucial in creating a high functioning adolescent bariatric program.

Abstract
BACKGROUND Patients who undergo vertical sleeve gastrectomy (VSG) are at risk of postoperative GERD. The reasons are multifactorial, but half of conversions to Roux-en Y gastric bypass are for intractable GERD. Our institution routinely performs preoperative pH and high-resolution manometry studies to aid in operative decision making. We hypothesize that abnormal pH studies in concert with ineffective esophageal motility would lead to higher rates of postoperative reflux after VSG. METHODS A single institution retrospective review was conducted of adult patients who underwent preoperative pH and manometry testing and VSG between 2015 and 2021. Patients filled out a symptom questionnaire at the time of testing. Postoperative reflux was defined by patient-reported symptoms at 1-year follow-up. Univariate logistic regression was used to examine the relationship between esophageal tests and postoperative reflux. The Lui method was used to determine the cutpoint for pH and manometric variables maximizing sensitivity and specificity for postoperative reflux. RESULTS Of 291 patients who underwent VSG, 66 (22.7%) had a named motility disorder and 67 (23%) had an abnormal DeMeester score. Preoperatively, reflux was reported by 122 patients (41.9%), of those, 69 (56.6%) had resolution. Preoperative pH and manometric abnormalities, and BMI reduction did not predict postoperative reflux status (p = ns). In a subgroup analysis of patients with an abnormal preoperative pH study, the Lui cutpoint to predict postoperative reflux was a DeMeester greater than 24.8. Postoperative reflux symptoms rates above and below this point were 41.9% versus 17.1%, respectively (p = 0.03). CONCLUSION While manometry abnormalities did not predict postoperative reflux symptoms, GERD burden did. Patients with a mildly elevated DeMeester score had a low risk of postoperative reflux compared to patients with a more abnormal DeMeester score. A preoperative pH study may help guide operative decision-making and lead to better counseling of patients of their risk for reflux after VSG.

Abstract
BACKGROUND Gastric sleeve stenosis (GSS) is an adverse event following sleeve gastrectomy for which objective tools are needed for diagnosis and treatment. Endoscopic treatment with serial pneumatic balloon dilation may relieve symptoms and prevent the need for conversion to Roux-en-Y gastric bypass. Endoluminal functional impedance planimetry (EndoFLIP) is an endoscopic tool that measures luminal diameter and distensibility indices (DI) and could be used to characterize severity of GSS. METHODS This was a retrospective analysis of a prospective database of patients referred for symptoms suggestive of GSS. Severity was determined at each endoscopy by a bariatric endoscopist blinded to EndoFLIP measurements. Successive pneumatic balloon dilations were performed until symptoms resolved; failure was defined as referral for conversion. EndoFLIP measurements of stenosis diameter and DI were obtained pre- and post-dilation. Primary outcomes were pre- and post-dilation luminal diameter and DI of GSS. Secondary outcomes were endoscopic severity of GSS, patient characteristics, and need for surgical revision. RESULTS 26 patients were included; 23 (85%) were female. Mean age was 45.3 (± 9.9) years. Mean number of dilations was 2.4 (± 1.3) and 10 (38%) patients were referred for conversion. Mild, moderate, and severe GSS was found in 10 (38%), 6 (23%), and 10 (38%) patients, respectively. Moderate and severe GSS underwent more dilations (2.5 ± 1.0 and 3.2 ± 1.6) than mild GSS (1.8 ± 0.8) and were more likely to be referred for conversion. Both pre- and post-dilation diameters were significantly larger in mild versus moderate or severe GSS. Additionally, pre- and post-dilation DI at 30 ml were significantly higher for mild compared to moderate and severe GSS. DISCUSSION EndoFLIP measurements correlate well with endoscopic assessment of GSS. While more data are needed to determine ideal balloon size and threshold measurements, our results suggest EndoFLIP may help expedite diagnosis and treatment of GSS.

Abstract
PURPOSE OF REVIEW Neurogastroenterology and motility is a rapidly evolving subspecialty that encompasses over 33% of gastroenterological disorders, and up to 50% of referrals to gastroenterology practice. It includes common problems such as dysphagia, gastroesophageal reflux disease, irritable bowel syndrome, chronic constipation, gastroparesis, functional dyspepsia, gas/bloating, small intestinal bacterial overgrowth, food intolerance and fecal incontinence Standard diagnostic tests such as endoscopy or imaging are normal in these conditions. To define the underlying mechanism(s)/etiology of these disorders, diagnostic motility tests are often required. These are best performed by well-trained personnel in a dedicated motility laboratory. Our purpose is to provide an up-to-date overview on how to organize and develop a motility laboratory based on our collective experiences in setting up such facilities in academia and community practice. RECENT FINDINGS A lack of knowledge, training and facilities for providing diagnostic motility tests has led to suboptimal patient care. A motility laboratory is the hub for diagnostic and therapeutic motility procedures. Common procedures include esophageal function tests such as esophageal manometry and pH monitoring, anorectal function tests suchlike anorectal manometry, neurophysiology and balloon expulsion, dysbiosis and food intolerance tests such as hydrogen/methane breath tests, and gastrointestinal transit assessment. These tests provide an accurate diagnosis and guide clinical management including use of medications, biofeedback therapy, neuromodulation, behavioral therapies, evidence-based dietary interventions and endoscopic or surgical procedures. Further, there have been recent developments in billing and coding of motility procedures and training requirements that are not well known. This review provides a stepwise approach on how to set-up a motility laboratory in the community or academic practice and includes the rationale, infrastructure, staffing needs, commonly performed motility tests and their clinical utility, billing and coding strategies, training needs and economic considerations for setting up this service.

Abstract
BACKGROUND Gastric sleeve stenosis (GSS) occurs in up to 4% of patients after laparoscopic sleeve gastrectomy (LSG). Typical symptoms include reflux, abdominal pain, dysphagia, and regurgitation. Serial pneumatic balloon dilation (PBD) is a successful treatment in many cases obviating the need for revisional surgery, but the potential for weight regain is unknown. The aim of the current study was to assess weight trends following serial pneumatic dilation for GSS. METHODS Retrospective analysis of a prospectively maintained database of patients undergoing serial PBD for GSS at one institution. Primary outcome was change in BMI before and after serial PBD. Secondary outcomes included complication rates and need for revisional surgery. Sub-group analyses were performed to determine the relationship of patient and procedural factors to BMI after PBD. RESULTS Forty-four patients met inclusion criteria, 34 (84.1%) women. Mean age was 46.7 (SD 11.9). Mean pre-sleeve BMI was 47.8 (SD 9.2), and mean BMI prior to first dilation was 34.2 (SD 6.8). Median follow-up was 395 days (range 48-571). Mean BMI at time of last follow up was 33.7 (SD 6.7). There was no statistical difference in BMI pre- or post-PBD (p 0.980). The lowest 10th and highest 90th BMI percentile trended toward a higher and lower BMI after PBD, respectively, though not significant. DISCUSSION As the prevalence of sleeve gastrectomy continues to rise, an increasing number of patients will require treatment for GSS. Stenosis is effectively treated with serial PBD in most patients without any impact on weight gain, making this an effective and appealing option for many patients.

Abstract
BACKGROUND Traditional endoscopic treatments have limited success in gastric sleeve stenosis (GSS). Gastric peroral endoscopic myotomy (G-POEM) could conceivably obliterate the twist/angulation that causes GSS through a tunneled stricturotomy. We report early outcomes of G-POEM for GSS treatment. METHODS We retrospectively reviewed all patients with GSS treated with G-POEM at our center. The primary end point was clinical success, defined as symptom improvement with resumption of adequate oral intake, without requiring further intervention. RESULTS 13 patients (mean age 43 ± 10.9 years; 12 female) underwent G-POEM for predominantly helical (11/13, 85 %) GSS. Three (23 %) had concurrent sleeve leak and 10 (77 %) had prior GSS treatment. Two intraoperative complications occurred, with no deviation to the procedure; no major complications occurred. At median follow-up of 175 (interquartile range [IQR] 119-260) days, clinical success was achieved in 10 patients (77 %). Median Gastroparesis Cardinal Symptom Index score in responders decreased from 2.06 (IQR 1.5-2.8) to 0.39 (IQR 0.2-0.5). Three patients (23 %) required surgical revision. CONCLUSIONS G-POEM was feasible and safe, and may provide an alternative option for those averse to undergoing surgical revision for treatment of GSS.

Quantifying Healthcare Utilization and Delay in the Treatment of Gastric Stenosis Following Sleeve Gastrectomy. Obes Surg 2021; 32:90-95. [PMID: 34585324 DOI: 10.1007/s11695-021-05704-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Revised: 08/31/2021] [Accepted: 09/02/2021] [Indexed: 01/06/2023]
Abstract
BACKGROUND Sleeve gastrectomy (SG) is the most common bariatric procedure performed. The incidence of gastric sleeve stenosis (GSS) is up to 4%, with a rising prevalence given increasing popularity of this surgery. GSS is best treated with pneumatic balloon dilation (PBD), but the diagnosis is not always straightforward, oftentimes leading to an extensive diagnostic workup. The aims of the current study were to quantify delay to treatment and overall healthcare utilization during this delay in patients with GSS following SG. METHODS This was a retrospective review of a prospectively collected database including patients with SG diagnosed with GSS between October 2017 and September 2020. The primary outcome was time between symptom development and treatment with PBD. Secondary outcomes included total healthcare utilization as reflected by the number and charges of imaging and emergency room (ER) visits. RESULTS Forty-five patients were included in the analysis; 37 (82%) were female. The mean (± SD) time to treatment was 755 (± 713) days. The probability of receiving treatment at 1, 2, and 3 years was 37%, 62%, and 76%, respectively. The mean (± SD) abdominal CT scans, radiographs, and UGIS between symptoms and PBD were 1.3 ± 2.0, 1.2 ± 1.6, and 1.2 ± 1.0, respectively. The mean number of ER visits was 1.9 ± 2.5 (range 0-8). The average number of diagnostic non-therapeutic upper endoscopies was 1.6 ± 1.5. The mean (± SD) total charges were $16,473 ± 15,173. CONCLUSION Patients who develop GSS following SG experience significant delay in diagnosis and management, reflected by multiple imaging studies, emergency department visits, and non-therapeutic procedures.

Abstract
Despite ongoing evolution in technique and a low mortality rate, clinicians may care for patients who suffer late complications (> 90 days of surgery) after bariatric surgery. Endoscopic techniques are used to identify and manage many of the late complications of the two most commonly performed bariatric surgeries: sleeve gastrectomy and Roux-en-Y gastric bypass. Stenosis at the incisura angularis and gastroesophageal reflux disease may occur in patients who have undergone a sleeve gastrectomy. Patients who underwent a Roux-en-Y gastric bypass can suffer marginal ulceration, gastrojejunal anastomotic stricture, and gastro-gastric fistula. Clinicians may also encounter biliary pathologies such as choledocholithiasis, chronic abdominal pain, and weight regain. This narrative review provides an update on the endoscopic evaluation and management of patients with late complications after sleeve gastrectomy or Roux-en-Y gastric bypass.

Quantification of gastric sleeve stenosis using endoscopic parameters and image analysis. Gastrointest Endosc 2021; 93:1344-1348. [PMID: 33316244 DOI: 10.1016/j.gie.2020.12.009] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/14/2020] [Accepted: 12/03/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND AND AIMS Sleeve gastrectomy has quickly become the most commonly performed bariatric surgery. In light of its increasing popularity, the prevalence of gastric sleeve stenosis (GSS) continues to rise. Management with serial pneumatic dilation is highly successful but underused because of a lack of quantitative diagnostic criteria. We aimed to develop quantifiable endoscopic criteria to characterize GSS based on the (1) ratio of narrowest to widest gastric lumen diameter, (2) endoscope angulation/trajectory required for passage, and (3) presence of bilious fluid pooling in the proximal sleeve and compare it with endoluminal functional lumen imaging probe (EndoFLIP) diameter and distensibility indices (DIs) and endoscopic documentation of gastric lumen morphology. METHODS We retrospectively reviewed a prospectively maintained database of patients undergoing endoscopy to assess for GSS. Endoscopic images were reviewed in a blinded fashion by 2 bariatric endoscopists. The narrowest and widest part of the gastric lumen diameters were noted on each image, in addition to a hypothetical trajectory required for endoscope passage. Using image processing software, we calculated the the ratio of diameters (ie, narrowest divided by widest) and angle of endoscope trajectory. The presence of bilious fluid pooling in the proximal gastric lumen was noted. These values were then compared with EndoFLIP parameters and endoscopic documentation of gastric lumen morphology. RESULTS Thirty patients met inclusion criteria, and 26 (87%) were found to have a stenosis on endoscopy. Of those, 9 (35%) were characterized as mild, 11 (42%) as moderate, and 6 (23%) as severe. There was no difference in demographic information between patients with and without stenosis. In patients with stenosis, mean EndoFLIP diameters and DIs were 12.9 ± 3.9 mm and 11.0 ± 6.8 mm2/mm Hg, respectively. In patients without stenosis, mean EndoFLIP diameters and DIs were 19.9 ± 2.9 mm and 21.5 ± 1.0 mm2/mm Hg, respectively. Patients with stenosis had significantly lower diameter ratios compared with those without stenosis (.27 ± .14 vs .48 ± .77, P = .01). Diameter ratios were also inversely related to severity of sleeve stenosis (β = -.08, P = .01). Patients with stenosis were also more likely to have fluid pooling (96.2% vs 25%, P < .001). There was no significant difference in the trajectory of endoscope passage between the 2 groups. CONCLUSIONS Endoscopic criteria for diagnosis of GSS are lacking. Our data suggest the ratio between the narrowest and widest gastric lumen diameters and presence of pooled fluid is associated with diagnosis of stenosis by EndoFLIP and gastric lumen morphology. Future studies to validate these criteria are needed.

Abstract
Recent innovations in esophageal diagnostic testing have enhanced gastroenterology clinical practice by facilitating more nuanced and advanced evaluation of esophageal symptoms. Among these pivotal advances is the FDA-approved functional lumen imaging probe (FLIP), which utilizes impedance planimetry via volumetric distension of a catheter-mounted balloon at the time of sedated upper endoscopy, to acquire esophageal dimensions and pressures. In real time, FLIP can display cross-sectional areas (CSA) and distensibility indices (ratios of CSA to intra-balloon pressures) throughout the esophagus, most notably at the esophagogastric junction, as well as secondary peristaltic esophageal body contractile patterns. As the use of FLIP has progressively spread and permeated into the practice of clinical gastroenterology since its introduction, increasing data on and experiences with its applications have accumulated to guide its utility in clinical practice. In this current review developed for gastroenterologists and foregut surgeons across clinical practice, we provide an introduction to FLIP technology and metrics and discuss the clinical scenarios in which performance of or referral for FLIP may be helpful in the evaluation and management of patients with commonly encountered esophageal symptoms and disorders. Specifically, we discuss the potential applications and limitations of FLIP as a complementary diagnostic modality in patients with non-obstructive dysphagia, established or suspected achalasia spectrum disorders, eosinophilic esophagitis, gastroesophageal reflux disease and those undergoing esophageal surgery.
