RESUMO
GOALS: Through evaluation of the lower esophageal sphincter immediately before and after myotomy using an endoluminal functional lumen imaging probe (EFLIP), our study aimed to determine the clinical response to peroral endoscopic myotomy (POEM) and the incidence of postprocedure reflux. BACKGROUND: Achalasia is a rare esophageal motility disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and diminished peristalsis. POEM is a therapeutic option for durable management of achalasia. However, symptomatic acid reflux and esophagitis are well-known adverse effects of the procedure. STUDY: Electronic medical records of 168 patients who underwent POEM for achalasia at 2 tertiary care referral centers from May 2014 to May 2021 were reviewed. EFLIP was used at a range of catheter fill volumes to assess LES dynamics. Preprocedure and postprocedure Eckardt Symptom Scores were recorded. RESULTS: Significant clinical improvement from POEM was sustained in over 94% of patients after 1 year. EFLIP changed intraprocedural management 5% of the time by means of myotomy extension. In patients with reflux>1 year following POEM, there was no significant difference in post-POEM LES diameter or change in LES diameter compared with those without reflux. However, post-POEM LES distensibility index (DI) was significantly higher in patients with reflux after 1 year compared with those without reflux. CONCLUSIONS: POEM is a safe and increasingly effective therapy for patients with symptomatic achalasia. Intraprocedural EFLIP measurements suggest that post-POEM reflux may be correlated more with DI than LES diameter. Yet, more data is needed to substantiate these outcomes.
RESUMO
Zenker per-oral endoscopic myotomy (ZPOEM) has become a promising technique for Zenker's diverticulum (ZD). The aim of this study was to add to the limited body of literature evaluating the safety and efficacy of ZPOEM. A prospectively maintained database was retrospectively reviewed to identify patients who underwent ZPOEM at two separate institutions between January 2020 and January 2022. Demographics, preoperative and postoperative clinical data, intraoperative data, adverse events, and length of stay were analyzed. A total of 40 patients (mean age 72.5 years, 62.5% male) were included. Average operative time was 54.7 minutes and average length of stay was 1.1 days. There were three adverse events, and only one was related to the technical aspects of the procedure. Patients showed improvement in the Functional Oral Intake Scale (FOIS) scores at 1 month (5 vs 7, p < 0.0001). The median FOIS scores remained 7 at both 6 and 12 months, although this improvement was not statistically significant at these time intervals (p = 0.46 and 0.37, respectively). Median dysphagia scores were decreased at 1 (2.5 vs 0, p < 0.0001), 6 (2.5 vs 0, p < 0.0001), and 12 months (2.5 vs 0, p = 0.016). The number of patients reporting ≥1 symptom was also decreased at 1 (40 vs 9, p < 0.0001) and 6 months (40 vs 1, p = 0.041). Although the number of patients reporting ≥1 symptom remained consistent at 12 months, this was not statistically significant (40 vs 1, p = 0.13). ZPOEM is a safe and highly effective treatment for the management of ZD. .

Background and study aims Endoscopic ultrasound-directed transgastric ERCP (EDGE) is a safe and efficacious procedure to treat pancreaticobiliary diseases in Roux-en-Y gastric bypass (RYGB). This multicenter study aimed to determine the long-term outcomes of EDGE focusing on fistula persistence rates and post-procedure weight change. Patients and methods Information about patients with Roux-en-Y gastric bypass anatomy who underwent EDGE between 2015 and 2021 from 10 institutions was captured in a registry. Patient demographics, procedural details, and clinical outcomes were analyzed. Results One hundred seventy-two patients were included in the study (mean age 60, 25â% male). Technical success of lumen-apposing metal stent (LAMS) placement was 171 of 172 (99.4â%) while clinical success of intervention was 95%. The mean procedure time was 65 minutes. The most commonly reported complication was stent dislodgement/migration (nâ=â29, 17). Mean length of time of LAMS duration was 69 days. Mean follow-up time was 6 months. Endoscopic fistula closure was performed in 40â% of patients (69/172) at the time of LAMS removal. Persistence of fistula was observed in 19 of 62 patients (31â%) assessed. Length of LAMS indwell time (days) was a predictor of persistent fistula. The average weight gain while the LAMS was in place was 12 lb in 63 patients (36.6â%); 59.4â% of patients gainedâ<â5 lb. Conclusions EDGE is a safe and efficacious procedure for RYGB patients requiring ERCP. Post-procedure evaluation and management of the enteral fistula varies widely among centers currently and would benefit from further standardization. Fistula persistence appears to be uncommon and can be managed endoscopically but may be related to length of indwell times of the LAMS.
RESUMO
Chylous mesenteric cysts represent a subgroup of uncommon, mostly benign intra-abdominal masses often identified incidentally on radiographs. Diagnosis is often challenging because these lesions cannot be reliably distinguished from hematomas or other cystic lesions without direct tissue sampling. In addition, data remains scarce regarding nonsurgical diagnostic and therapeutic options for these cysts. This case describes an endoscopic option for a uniquely located chylous cyst.
RESUMO
INTRODUCTION: Endoscopic management of Zenker diverticuli (ZD) has traditionally been via septotomy technique. The recent development of tunneling technique has shown to be both efficacious and safe. The aim of this study is to evaluate the tunneling technique using per oral endoscopic myotomy (Z-POEM) versus septotomy. METHODS: Patients who underwent endoscopic management of ZD either by Z-POEM or septotomy from March 2017 until November 2020 from 9 international academic centers were included. Demographics, clinical data preprocedure and postprocedure, procedure time, adverse events, and hospital length of stay were analyzed. RESULTS: A total of 101 patients (mean age 74.9 y old, 55.4% male) were included: septotomy (n=49), Z-POEM (n=52). Preprocedure Functional Oral Intake Scale score and Eckardt score was 5.3 and 5.4 for the septotomy group and 5.9 and 5.15 for the Z-POEM group. Technical success was achieved in 98% of the Z-POEM group and 100% of the septotomy group. Clinical success was achieved in 84% and 92% in the septotomy versus Z-POEM groups. Adverse events occurred in 30.6% (n=15) in septotomy group versus 9.6% (n=5) in the Z-POEM group (P=0.017). Reintervention for ongoing symptoms occurred in 7 patients in the septotomy group and 3 patients in the Z-POEM group. Mean hospital length of stay was shorter for the Z-POEM group, at 1.5 versus 1.9 days. CONCLUSIONS: A tunneling technique via the Z-POEM procedure is an efficacious and safe endoscopic treatment for ZD. Z-POEM is a safer procedure with a statistically significant reduction in adverse events compared with traditional septotomy technique.

Candy cane syndrome is an underappreciated complication reported in bariatric patients following Roux-en-Y gastric bypass. It results from an excessively long blind afferent Roux limb at the gastrojejunostomy that can lead to food accumulation. Patients often present with nausea, vomiting, food intolerance, acid reflux, and abdominal pain. Many patients remain undiagnosed due to vague gastrointestinal symptoms, delayed presentation, and physician unawareness. Here, we present the case of a 40-year-old female who presented for a third opinion on the cause of intractable acid reflux and nausea. Workup revealed her symptoms stemmed from an excessively long afferent Roux limb. Traditionally, treatment would include laparoscopic or open surgical removal of the blind limb. Although effective, surgical intervention is invasive, may not be an option in high-risk patients, and can lead to further complications. We were able to successfully address this patient's candy cane syndrome by utilizing a novel endoscopic approach to revise the gastrojejunal anastomosis, which led to full resolution of her symptoms. Endoscopic therapy of candy cane syndrome may provide a minimally invasive approach that exposes patients to decreased procedural risk while potentially producing similar treatment results as more invasive surgical approaches.

Rocky Mountain spotted fever (RMSF) is a tick-borne illness caused by Rickettsia rickettsii. The classic triad of fever, rash, and a recent tick bite is rarely present at diagnosis. Less known, but more common initial presentations include gastrointestinal symptoms such as anorexia, nausea, vomiting, and abdominal pain. In endemic areas, a persistent fever with gastrointestinal symptoms should prompt screening and early initiation of antibiotics to prevent the development of fulminant RMSF and its associated high mortality. This case aims to educate about the gastrointestinal and hepatic manifestations of this diagnostic enigma.
RESUMO
INTRODUCTION: We assessed the influence of a best practice alert (BPA) embedded within the electronic medical record on improving hepatitis C virus (HCV) birth-cohort screening by primary care physicians (PCPs). METHODS: Screening by 155 PCPs was monitored during 2 consecutive 9-month periods before and after implementation of the BPA. All tests were reviewed to differentiate true screening from other testing indications. RESULTS: Of 155 PCPs, 131 placed screening orders before and after BPA. Twenty-two PCPs started testing after BPA (P = 0.02). The number of tests placed and screening rates per PCP increased from 16 to 84 and from 3.3% to 13.2%, respectively (P < 0.0001). Before BPA, most PCPs rarely ordered screening HCV tests, whereas a small group of physicians generated most tests, indicative of an underlying power-law distribution. After the BPA, a new group of high-performing PCPs emerged, whose screening patterns were again characterized by a power-law distribution. However, pre-BPA test rates of individual PCPs were not predictive of their post-BPA rates. Overall, the introduction of the BPA narrowed the gap between low- and high-performing testers, indicating that modest increases in testing by a large number of low-performing PCPs could drive substantial improvement in program implementation. DISCUSSION: HCV birth-cohort screening by PCPs was shaped by an underlying power-law distribution. This distribution was preserved after the implementation of a BPA, although pre-BPA test rates were not predictive of post-BPA rates. Increases in test rates by high- and low-performing PCPs both contributed to the overall success of the BPA.
