Background Treatment of Zenker’s diverticulum has evolved from open surgery to endoscopic techniques, including flexible and rigid endoscopic septotomy, and more recently, peroral endoscopic myotomy (Z-POEM). This study compared the effectiveness of flexible and rigid endoscopic septotomy with that of Z-POEM. Methods Consecutive patients who underwent endoscopic septotomy (flexible/rigid) or Z-POEM for Zenker’s diverticulum between 1/2016 and 9/2019 were included. Primary outcomes were clinical success (decrease in Dakkak and Bennett dysphagia score to ≤ 1), clinical failure, and clinical recurrence. Secondary outcomes included technical success and rate/severity of adverse events. Results 245 patients (110 females, mean age 72.63 years, standard deviation [SD] 12.37 years) from 12 centers were included. Z-POEM was the most common management modality (n = 119), followed by flexible (n = 86) and rigid (n = 40) endoscopic septotomy. Clinical success was 92.7 % for Z-POEM, 89.2 % for rigid septotomy, and 86.7 % for flexible septotomy (P = 0.26). Symptoms recurred in 24 patients (15 Z-POEM during a mean follow-up of 282.04 [SD 300.48] days, 6 flexible, 3 rigid [P = 0.47]). Adverse events occurred in 30.0 % rigid septotomy patients, 16.8 % Z-POEM patients, and 2.3 % flexible septotomy patients (P < 0.05). Conclusions There was no difference in outcomes between the three treatment approaches for symptomatic Zenker’s diverticulum. Rigid endoscopic septotomy was associated with the highest rate of complications, while flexible endoscopic septotomy appeared to be the safest. Recurrence following Z-POEM was similar to flexible and rigid endoscopic septotomy. Prospective studies with long-term follow-up are required. ^* Sarah S.

Background Cricopharyngeal bars (CPBs) are a unique etiology of oropharyngeal dysphagia. Symptomatic patients are managed with endoscopic dilation or surgical myotomy. Cricopharyngeal peroral endoscopic myotomy (CP-POEM) is an emerging technique for the management of dysphagia due to CPBs. This study evaluated technical success, clinical success, adverse events, and long-term recurrence following CP-POEM. Methods Consecutive patients who underwent POEM for management of CPBs between May 2015 and December 2020 at four tertiary care centers were included. Primary outcome was clinical success (defined as improvement of dysphagia score to ≤ 1). Secondary outcomes were technical success, rate and severity of adverse events, procedure duration, and symptom recurrence. Results 27 patients (mean age 69 years; 10 female) underwent CP-POEM during the study period. The most common presenting symptoms at the time of index procedure were dysphagia (26; 96.3 %) and regurgitation (20; 74.1 %). Clinical and technical success were achieved in all patients. Mild/moderate adverse events occurred in two patients (7.4 %). CP-POEM significantly reduced the median dysphagia score. Conclusions CP-POEM was a safe and effective treatment for symptomatic CPBs. Although symptom recurrence was low, long-term outcome data are needed. CP-POEM should be considered as a management option for symptomatic CPBs at centers with POEM expertise. ^* Co-first authors.

Liver disease forms a global health burden and is a cause of significant morbidity and mortality. Good patient education has proven to be a key tool in disease management, providing significant benefit in knowledge and behavioral modifications. To develop effective educational tools, a good understanding of patient educational needs and preferred learning methods is necessary. Few studies have evaluated the educational needs of patients with liver disease. This study aims to assess the educational needs of patients at a large tertiary liver center. This study was a questionnaire-based cross-sectional study evaluating patient demographics,perceived and unperceived educational needs (hepatitis B and hepatitis Cknowledge) at a tertiary liver centre A total of 300 patients completed the questionnaire. Most patients stated they were “extremely” or “quite” interested in learning more about their liver condition (84.9%, n=242), in either “moderate” or “a lot of” detail (94.6%, n=202). There was no association between gender, age, level of education, annual income and interest of patients in learning more about their liver condition. There was a significant association between number of clinic visits and interest to learn more (p=0.022), but there was no association between the duration of their follow-up at the clinic and their interest to learn more (p=0.243). Overall, patients showed great interest in learning more about their liver condition, potentially indicating a need for more educational programs. Most patients prefer reading (via internet or pamphlets/brochures) or one-to-one discussions, giving us a good sense of potentially successful educational strategies that will fit the needs of most patients.

Rectal cancer demonstrates a characteristic natural history in which benign rectal neoplasia precedes malignancy. The worldwide burden of rectal cancer is significant, with rectal cancer accounting for one-third of colorectal cancer cases annually. The importance of early detection and successful management is essential in decreasing its clinical burden. Minimally invasive treatment of rectal neoplasia has evolved over the past several decades, which has led to reduced local recurrence rates and improved survival outcomes. The approach to diagnosis, staging, and selection of appropriate treatment modalities is a multidisciplinary effort combining interventional endoscopy, surgery, and radiology tools. This review examines the currently available minimally invasive endoscopic and surgical management options of rectal neoplasia.
