RESUMO
PURPOSE: Rising obesity and type 2 diabetes mellitus (T2DM) rates can be mitigated by various strategies, with a 10% total body weight loss (TBWL) threshold often required for T2DM remission. T2DM remission rates after bariatric surgery like Roux-en-Y gastric bypass (RYGB) are well established; endoscopic sleeve gastroplasty (ESG) is a less invasive option that averages 15% TBWL and allows for T2DM remission. This study explores the DiaRem (Diabetes Remission post-RYGB) score's ability to predict T2DM remission 1-year post-ESG. MATERIALS AND METHODS: We conducted a retrospective cohort study on 39 individuals with T2DM who underwent ESG. Age, utilization of diabetes medications, insulin administration, and hemoglobin A1c levels were used to calculate the DiaRem score. The area under the receiver operating characteristic curve (AUC) was employed to evaluate the discriminative ability of DiaRem in distinguishing diabetes remission. RESULTS: Among the 39 patients with a median hemoglobin A1c of 6.7, 12.8% required insulin, and 43.6% used diabetes medication. At 1-year post-ESG, 69.2% of patients experienced diabetes remission with a median %TWBL of 12.7. The DiaRem score's ability to detect diabetes resolution for ESG patients had a sensitivity of 100% and a specificity of 58.3%, at the optimal cutoff value of 10. The AUC was 0.779 (95% CI 0.546-0.959). CONCLUSION: Our study demonstrated the DiaRem score's predictive value for T2DM remission post-ESG, highlighting its utility in clinical decision-making for ESG-related outcomes. Further investigation is needed to identify alternative indicators that may enhance predictive accuracy, thus refining personalized decision-making for this patient group.
RESUMO
OBJECTIVE: Endoscopic retrograde cholangiopancreatography (ERCP) may be unsuccessful in patients with duodenal stenosis or malignant ampullary infiltration. Endoscopic ultrasound-guided biliary drainage (EUS-BD) has been proposed as an alternative. We aimed to assess the efficacy and safety of EUS-BD for malignant distal bile duct obstruction using the newly introduced smaller caliber 6 or 8 mm cautery-enhanced lumen-apposing metal stent. METHODS: A multicenter retrospective study was performed on patients with unresectable malignant distal bile duct obstruction who underwent EUS-BD between 2021 and 2022 after unsuccessful ERCP. RESULTS: Thirty-two patients were included [7 (53.13%) males], with a mean age of 72.2 ± 12.5 years. The technical success rate was 100%. Altered anatomy was present in 2 (6.25%). The indication for drainage was biliary obstruction from pancreatic cancer in 26 patients (84.5%), cholangiocarcinoma in 3 (9.4%), and ampullary mass in 3 (9.4%). The procedure was performed mostly in an outpatient setting (n = 19, 59.38%). The clinical success rate was 92.3% [bilirubin: 14.1 (SD: 8.9) preprocedure vs 4.9 (SD: 1.1) postprocedure; P = 0.0001]. There was one early adverse event of a perforation, which was closed endoscopically and drained percutaneously. Delayed adverse events included food impaction of the stent (n = 1), which was resolved with a repeat procedure and insertion of a double pigtail stent. CONCLUSION: This study demonstrates the feasibility of EUS-BD drainage using smaller caliber 6 or 8 mm lumen-apposing metal stent to relieve malignant distal bile duct obstruction in patients who fail conventional ERCP.
RESUMO
INTRODUCTION: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is frequently used to risk-stratify pancreatic cystic lesions (PCLs). Rising PCL incidence and developments in tissue acquisition and specimen analysis necessitate updated appraisal of EUS-FNA safety, particularly the risk of postprocedure pancreatitis, the most common EUS-FNA-related adverse event. Our systematic review aims to accurately quantify the risk of EUS-FNA-related pancreatitis to best inform decisions regarding EUS-FNA's optimal role in PCL workup. METHODS: We performed systematic searches in 4 databases from inception to April 2024 for original English-language studies investigating EUS-FNA-related pancreatitis. We extracted data on demographics and EUS-FNA-related pancreatitis risk, severity, and risk factors. These were meta-analyzed through the DerSimonian Laird Method using a random-effects model. Meta-regression of pancreatitis risk was performed to delineate associations with clinical and procedural characteristics. RESULTS: Sixty-four studies comprised 8,086 patients and reported 110 EUS-FNA-related pancreatitis events. Pooled risk of EUS-FNA-related pancreatitis was 1.4% (95% confidence intervals, -0.8% to 3.5%; I2 = 0.00), which was predominantly of mild severity (67%) and uniformly nonfatal. Pancreatitis risk lacked significant association with sample size, age, sex, cyst size, needle caliber, or passes, although we noted trends toward higher risk in studies published after 2015, those using higher gauge needles (19 G vs 22 G/25 G), and those performing EUS-guided through-the-needle biopsy. DISCUSSION: We note with high certainty that pancreatitis after EUS-FNA of PCLs is infrequent and mild in severity with no mortality in the included cohort. EUS-guided through-the-needle biopsy may serve as a significant risk factor for EUS-FNA-related pancreatitis risk; however, further studies are needed to delineate other predisposing characteristics.
RESUMO
Obesity is a complex disease process, which often requires multifactorial, patient-tailored strategies for effective management. Treatment options include lifestyle optimization, pharmacotherapy, endobariatrics, and bariatric metabolic endoscopy. Obesity-based interventions can be challenging in patient populations with severe obesity, particularly post-gastric bypass. We report the case of a non-surgical patient with a failed remote open gastric bypass, who underwent an endoscopic small bowel diversion procedure, resulting in partial caloric diversion, via the creation of an EUS-guided jejunocolostomy (EUS-JC). The procedure is an extension of prior reported EUS-guided and magnet-based small bowel bypass procedures, in this case, for the purposes of weight loss (Kahaleh et al., 1; Jonica et al. Gastrointest Endosc. 97(5):927-933, 2; Machytka et al. Gastrointest Endosc. 86(5):904-912, 3;). The procedure was performed without peri-procedural complications, with effective weight loss during follow-up. Endoscopic bariatric interventions that target the small bowel, such as EUS-JC, offer promising tools for obesity management and should be studied further. Numerous factors including lifestyle, psychosocial, genetic, behavioral, and secondary disease processes contribute to obesity. Severe obesity (defined as a BMI > 50 kg/m2) is associated with increased morbidity and mortality with a significantly reduced response to treatment (Flegal et al. JAMA. 309(1):71-82, 4;). Weight regain can be noted in up to 50% of patients post-RYGB. In populations with severe obesity, there is an associated 5-year surgical failure rate of 18% (Magro et al. Obesity Surg. 18(6):648-51, 5;). These patients may not be surgical candidates for revision or can develop post-revision chronic protein-caloric malnutrition (Shin et al. Obes Surg. 29(3):811-818, 6;). Lifestyle, modification, pharmacotherapy, or endoscopic transoral reduction (TORe) can be effective generally; however, in patients with severe obesity, the total desired excess body weight loss may not likely be accomplished solely by these strategies. An endoscopic small bowel intervention that diverts a portion of caloric intake from small bowel absorption can potentially promote weight loss similar to a surgical lengthening of the Roux limb (Shah et al. Obes Surg. 33(1):293-302, 7; Hamed et al. Annal Surg. 274(2):271-280, 8;), in the sense that there is a reduction in the total small bowel surface area for absorption. Roux limb distalization can be effective for weight regain for post bypass patients. The EUS-JC technique aims to work similarly by reducing the total small bowel surface area utilized for absorption. Since this patient was deemed a non-surgical candidate, an EUS-guided jejunocolostomy was offered. Prior to the procedure, the patient established longitudinal care with our bariatric nutritionist and obesity medicine services. Extensive pre-bariatric labs were screened to rule out confounders for recurrent severe obesity. Intra-procedure, the patient received one dose of 500 mg intravenous levofloxacin. Post-procedure, loperamide was prescribed every 8 h as needed for post-procedure diarrhea. Within 2 weeks, the patient was no longer taking anti-diarrheals. The post-procedure diet consisted of a liquid diet for 2 days before advancement to a low-residue diet for 1 month, and then a regular diet.

BACKGROUND AND AIMS: The application of endoscopic suturing has revolutionized defect closures. Conventional over-the-scope suturing necessitates removal of the scope, placement of the device, and reinsertion. A single channel, single sequence, through-the-scope suturing device has been developed to improve this process. This study aims to describe the efficacy, feasibility, and safety of a through-the-scope suturing device for gastrointestinal defect closure. METHODS: This was a retrospective multicenter study involving 9 centers of consecutive adult patients who underwent suturing using the X-Tack Endoscopic HeliX Tacking System (Apollo Endosurgery). The primary outcomes were technical success and long-term clinical success. Secondary outcomes included adverse events, recurrence, and reintervention rates. RESULTS: In all, 56 patients (mean age 53.8, 33 women) were included. Suturing indications included fistula repair (n=22), leak repair (n=7), polypectomy defect closure (n=12), peroral endoscopic myotomy (POEM) site closure (n=7), perforation repair (n=6), and ulcers (n=2). Patients were followed at a mean duration of 74 days. Overall technical and long-term clinical success rates were 92.9% and 75%, respectively. Both technical and clinical success rates were 100% for polypectomies, POEM-site closures, and ulcers. Success rates were lower for the repair of fistulas (95.5% technical, 54.5% clinical), leaks (57.1%, 28.6%), and perforations (100%, 66.7%). No immediate adverse events were noted. CONCLUSION: This novel, through-the-scope endoscopic suturing system, is a safe and feasible method to repair defects that are ≤3 cm. The efficacy of this device may be better suited for superficial defects as opposed to full-thickness defects. Larger defects will need more sutures and probably a double closure technique to provide a reinforcement layer.
RESUMO
BACKGROUND: Endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) is frequently used to obtain core samples of solid lesions. Here, we describe and evaluate a novel hydrostatic stylet (HS) technique designed to optimize core sample acquisition, reporting diagnostic yield, efficacy, and safety relative to the conventional stylet slow-pull (SP) technique. METHODS: A novel HS technique was developed and validated retrospectively. Consecutive patients who underwent EUS-FNB with core biopsy of solid lesions through either the HS or SP technique between January 2020 and April 2022 were included. Exclusion criteria included cystic lesions, nonlesional liver biopsies, and specimens sent for cytologic analysis only. Patient and lesion characteristics, number of passes, sample adequacy, and adverse events were compared between the two techniques. RESULTS: A total of 272 patients were included with 138 in the HS group and 134 in the SP group. Lesion size and anatomic distribution were similar in both groups. Compared with the SP approach, the HS technique demonstrated significantly higher sample adequacy (97.8% vs 83.6%, P < 0.001), higher sensitivity (97.1% vs 89.7%, P = 0.03), and lower mean number of passes (1.2 vs 3.3, P < 0.001). Rates and severity of adverse events in the HS group were comparable to the SP group and existing literature. Similar associations were observed in pancreatic and nonpancreatic lesion subanalyses. CONCLUSIONS: The novel HS technique demonstrated excellent biopsy sample adequacy and diagnostic yield while requiring fewer passes to obtain diagnostic specimens compared with a conventional EUS-FNB approach. Further prospective evaluation is needed to confirm these pilot findings and optimize EUS-FNB acquisition techniques.

Background and study aims Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) is an emerging procedure that lacks technical standardization with limited adoption beyond expert centers. We surveyed high-volume endosonographers about the technical aspects of EUS-GE to describe how the procedure is currently performed at expert centers and identify targets for standardization. Methods Invitations to complete an electronic survey were distributed to 21 expert EUS practitioners at 19 U.S. centers. Respondents were surveyed about technical aspects of EUS-GE, indications, efficacy, safety, and attitudes toward the procedure. Results All 21 (100%) invited expert endoscopists completed the survey. Nine (42.9%) reported performing >10 EUS-GEs in the last 12 months. About half (47.6%, 10/21) puncture the target loop prior to lumen-apposing metal stent (LAMS) introduction, most often to confirm the loop is jejunum. No respondents reported guidewire placement prior to LAMS introduction. Most (71.4%, 15/21) do not use a guidewire at any time, while 28.6% (6/21) reported wire placement after distal flange deployment to secure the tract during apposition. Eight (38.1%, 8/21) reported at least one major adverse event, most commonly intraperitoneal LAMS deployment (87.5%, 7/8). Factors most often reported as advantageous for EUS-GE over enteral stenting included lack of papilla interference (33.3%, 7/21) and decreased occlusion risk (23.8%, 5/21). Conclusions Significant variation in performance technique for EUS-GE exists among expert US endoscopists, which may hinder widespread adoption and contribute to inconsistencies in reported patient outcomes. The granularity provided by these survey results may identify areas to focus standardization efforts and guide future studies on developing an ideal EUS-GE protocol.

RESUMO
BACKGROUND AND AIMS: No studies have evaluated trainees' outcomes when learning ERCP with patients in the supine and prone positions simultaneously. We aimed to assess whether patient position impacts procedural outcomes and learning curve. METHODS: We prospectively evaluated patients undergoing ERCP by a supervised advanced endoscopy trainee (AET) at a tertiary care center. Adult patients with native papillae were included. The AET was universally given 5 attempts per cannulation. Outcomes were evaluated quarterly. RESULTS: Successful cannulation was achieved in 44 supine (69%) and 17 prone (68%) patients (P = .95). Although mean time to reach the papilla was shorter in the supine patient position, time to biliary cannulation (7.8 vs 9.4 minutes, P = .53) and number of attempts were similar. A stepwise increase was seen in cannulation rates throughout the academic year (P < .01) and increased more in supine patients (P = .01). Procedure and total room times were shorter in supine patients. CONCLUSIONS: Shorter procedure and room turnover times and a comparable cannulation rate were found for supine versus prone ERCP.

BACKGROUND AND AIMS: Palliation of malignant gastric outlet obstruction (mGOO) allows resumption of peroral intake. Although surgical gastrojejunostomy (SGJ) provides durable relief, it may be associated with a higher morbidity, interfere with chemotherapy, and require an optimum nutritional status. EUS-guided gastroenterostomy (EUS-GE) has emerged as a minimally invasive alternative. We aimed to conduct the largest comparative series to date between EUS-GE and SGJ for mGOO. METHODS: This multicenter retrospective study included consecutive patients undergoing SGJ or EUS-GE at 6 centers. Primary outcomes included time to resumption of oral intake, length of stay (LOS), and mortality. Secondary outcomes included technical and clinical success, reintervention rates, adverse events (AEs), and resumption of chemotherapy. RESULTS: A total of 310 patients were included (EUS-GE, n = 187; SGJ, n = 123). EUS-GE exhibited significantly lower time to resumption of oral intake (1.40 vs 4.06 days, P < .001), at lower albumin levels (2.95 vs 3.33 g/dL, P < .001), and a shorter LOS (5.31 vs 8.54 days, P < .001) compared with SGJ; there was no difference in mortality (48.1% vs 50.4%, P = .78). Technical (97.9% and 100%) and clinical (94.1% vs 94.3%) success was similar in the EUS-GE and SGJ groups, respectively. EUS-GE had lower rates of AEs (13.4% vs 33.3%, P < .001) but higher reintervention rates (15.5% vs 1.63%, P < .001). EUS-GE patients exhibited significantly lower interval time to resumption of chemotherapy (16.6 vs 37.8 days, P < .001). Outcomes between the EUS-GE and laparoscopic (n = 46) surgical approach showed that EUS-GE had shorter interval time to initiation/resumption of oral intake (3.49 vs 1.46 days, P < .001), decreased LOS (9 vs 5.31 days, P < .001), and a lower rate of AEs (11.9% vs 17.9%, P = .003). CONCLUSIONS: This is the largest study to date showing that EUS-GE can be performed among nutritionally deficient patients without affecting the technical and clinical success compared with SGJ. EUS-GE is associated with fewer AEs while allowing earlier resumption of diet and chemotherapy.
