Article Abstract
Background: Endoscopic resection (ER) of tumors causes inflammation, edema, fibrosis, and adhesions in the surrounding tissue. However, little is known about the effect of ER on subsequent laparoscopic surgery for rectal tumors. The objective of this retrospective study was to analyze the effect of ER on subsequent laparoscopic surgery for rectal tumors.
Methods: Twenty-eight patients underwent laparoscopic surgery for rectal adenocarcinoma with submucosal invasion or a rectal neuroendocrine tumor at our hospital between January 2005 and December 2012. A group of 14 patients who underwent laparoscopic surgery with previous ER was compared to a group of 14 patients who underwent laparoscopic surgery without previous ER.
Results: Though most fibrosis involved the submucosa after polypectomy and endoscopic mucosal resection, fibrosis after endoscopic submucosal dissection involved the muscularis propria in two patients, and the subserosa in one patient. There were no statistically significant differences in clinical outcomes between the groups.
Conclusion: Laparoscopic surgery after ER for rectal tumors is safe and feasible. Laparoscopic surgery is the reasonable first-choice for radical treatment of rectal tumors after ER.

Laparoscopic cholecystectomy for acute cholecystitis carries an increased risk of biliovascular injuries. Fluorescence cholangiography (FC) is a valuable diagnostic tool for identifying extrahepatic bile ducts (EHBD). The objective of this study was to evaluate the efficacy of FC in delineating EHBD anatomy, both before and after dissection, based on the critical view of safety (CVS) principles.

: Metabolic and bariatric surgery (MBS) is a well-established treatment for severe obesity, yet its effects in patients with inflammatory bowel disease (IBD) are not well understood. MBS in this population presents unique challenges, including the potential for exacerbating inflammatory disease activity and causing complications such as malnutrition and medication malabsorption. This study aims to assess the long-term outcomes of MBS in IBD patients, focusing on both metabolic outcomes and its impact on the course of IBD.

Gastroesophageal reflux disease (GERD) affects millions globally, with traditional treatments like proton pump inhibitors (PPIs) and surgical fundoplication presenting challenges such as long-term medication dependency and disturbing long term side effects following surgery. This review explores emerging, alternative therapies that offer less invasive, personalized alternatives for GERD management. Endoscopic approaches, including Stretta therapy, transoral incisionless fundoplication (TIF), and endoscopic full-thickness plication (EFTP), demonstrate promising but also controversial outcomes in symptom relief and reduced acid exposure.
