Summary: The management of duodenal neuroendocrine tumors (DNETs) varies depending on the size of the lesion, with smaller ones typically treated by endoscopic mucosal resection (EMR) and larger ones by surgical resection (SR). A study comparing outcomes between patients who underwent EMR and SR showed that there was no significant difference in survival rates, particularly in 1-2 cm DNETs. However, surgically resected DNETs had improved progression-free survival (PFS) and overall survival (OS) compared to jejunoileal NETs.

Summary: Thermal ablation of the defect margin after endoscopic mucosal resection (EMR-T) has been shown to significantly reduce residual or recurrent adenoma (RRA) at first surveillance colonoscopy. In an international multi-center prospective trial, EMR-T was found to be a simple, inexpensive, and highly effective auxiliary technique for managing large nonpedunculated colorectal polyps.

Summary: This study presents a modified underwater endoscopic mucosal resection (UEMR) method for treating intermediate-sized colorectal polyps. The results showed high rates of complete and en bloc resection, with a 100% technical success rate. Careful treatment is required for polyps larger than 15 mm.

Summary: This study compared the outcomes of endoscopic treatment for different sizes of duodenal neuroendocrine tumors (DNET). The study found that in lesions smaller than 10 mm, both conventional EMR and modified EMR had similar histologic complete resection rates, but the modified EMR group had a higher risk of perforation. Overall, endoscopic treatment is feasible and effective for nonampullary DNET sized less than 10 mm and limited to mucosal and submucosal layer.

Summary: This study compared treatment outcomes between underwater endoscopic mucosal resection (U-EMR) and conventional endoscopic mucosal resection (C-EMR) for patients with nonampullary duodenal epithelial tumors (NADETs) and found that the resectability was comparable. Despite no significant differences in adverse events and en bloc resection rates between the two groups, the U-EMR group had significantly shorter procedure time.

Summary: This study investigated the efficacy of endoscopic retreatment for residual or recurrent adenoma after endoscopic mucosal resection (EMR) of large non-pedunculated colorectal polyps (LNPCPs) of >= 20mm. The results showed that endoscopic retreatment is an effective treatment method, with long-term adenoma remission of over 90%.

Summary: This study compared the detection rate and stage of metachronous gastric cancer (MGC) between biannual and annual endoscopic surveillance after endoscopic resection (ER) for early gastric cancer (EGC) or high-grade dysplasia (HGD). The results showed no significant difference in the detection rate of MGC between biannual and annual surveillance, but biannual surveillance had a higher detection rate, especially for patients with moderate to severe gastric atrophy, during the first 3 years.

Summary: The study found that the use of CSI-EMR does not increase the complete or en bloc resection rate of colorectal lesions with SSL endoscopic features, but does increase the R0 resection rate. Although the procedure time is longer for CSI-EMR, there is no significant difference in adverse events or recurrence rate compared to EMR. Further evaluation is needed to assess the association of CSI-EMR with R0 resection and non-recurrence.

Summary: This study investigates the image-guided control of a robotic flexible endoscopic system equipped with an OCT probe for autonomous tissue scanning. The control strategy allows the OCT probe to automatically track user-defined trajectories and control orientation, depth, and endoscopic image position. A marker-based 3D pose estimation method is proposed based on a Kalman filter and registration technique, with validation through simulation and laboratory experiments.

Summary: This study surveyed postoperative patients to explore their perceptions of neighborhood and built environment resources, and found that the patients had the highest access to lower-cost national food retailers and fitness facilities. Financial challenges were identified as the major barrier in finding food products to meet patients' goals, while patients expressed a need for better trained staff and facilities in fitness centers. Patients reported highest access to walking/running trails, city parks, and sidewalks for outdoor physical activities.

Summary: By integrating electronic health records, census data, and county data, this study explores disparities in social determinants of health (SDoH) and weight loss among bariatric surgery patients in Ohio. The findings suggest that proximity to food stores is associated with better weight loss over a two-year period, and lower poverty levels do not negatively affect weight loss in Black patients.

Summary: This study aimed to investigate the association between patients' initial preoperative psychological evaluation outcomes and current psychiatric diagnoses with postoperative outcomes. The results showed that patients who received a clinical decision of RFU had higher weights over 12 months compared to those in the NFU group, but this association was not found for percent total weight loss and other psychiatric variables.

Summary: Although bariatric surgery is the most effective treatment for severe obesity, a proportion of patients experience weight regain after surgery. The causes of weight regain are not well-defined, but dysregulated/maladaptive eating behaviors, lifestyle factors, and physiological compensatory mechanisms are believed to contribute. Current interventions, including dietary, supportive, behavioral, and exercise approaches, have not shown significant impact on weight regain. Future studies should aim to better understand the etiologies of weight regain and develop non-surgical interventions with demonstrated efficacy in rigorous trials.

Summary: This study used a non-invasive, ingestible sampling device to collect and analyze intestinal samples and stool samples from 15 healthy participants. The research found significant differences in food metabolites between stool and intestines, and the intestinal metabolome can reflect the connection between diet, host, and microbial metabolism.

Summary: Mixed esophageal disease (MED) is a disorder that affects the structure and/or function of the esophagus, presenting symptoms and signs that resemble or partially resemble other well-defined esophageal conditions. The MED concept emphasizes the overlap syndrome, incorporating various clinical, endoscopic, imaging, and functional features that have an impact on the patient's quality of life, prognosis, and management. This article focuses on frequently encountered MED scenarios in medico-surgical practices worldwide, highlighting the need for better understanding and management to improve outcomes and prognosis. Proper recognition, definition, and a collaborative, multidisciplinary approach are crucial in optimizing therapeutic outcomes while minimizing complications.

Summary: This study assessed the relative utility of the London classification in the decision-making of patients with chronic constipation (CC) by comparing wireless motility capsule (WMC) and high-resolution anorectal manometry (HR-ARM) results. It was found that anorectal dysfunction had a high prevalence in patients with slow colonic transit time (CTT) regardless of the classification criteria. Therefore, the specificity and utility of WMC and HR-ARM in assessing patients with CC need further investigation.

Summary: This study aimed to investigate the impact of selecting different gastric reference sensors on IRP measurement and diagnosis. The results showed that choosing different reference sensors could lead to variations in IRP values, resulting in inconsistent diagnoses in 28% of HRM studies. Selecting the correct gastric reference sensor is crucial for accurate test results and avoiding misdiagnosis.

Summary: This study analyzed patient engagement with a virtual patient navigation platform (VPNP) designed to guide bariatric surgery candidates through the pre-operative workup. The study found that the majority of patients did not engage with the app, and non-engagement was associated with lower rates of private insurance. The SUS survey showed high perceived usability of the VPNP, but future work will focus on addressing reasons for non-engagement to improve patient participation.
