Laparoscopic resection is a standard procedure for gastric submucosal tumors. Herein, we analyzed the features of various laparoscopic approaches. ⋯ For gastric submucosal tumors with appropriate locations and growth types, laparoscopic tailored resection which facilitates safer and more precise resection can be good alternative treatment option.

Per-oral endoscopic myotomy (POEM) is an emerging treatment for achalasia. Pneumatic dilation, botulinum toxin injection, and previous myotomy increase the difficulty of subsequent Heller myotomy, but their impact on POEM remains unknown. The purpose of this study was to compare patients who had undergone prior treatment for their achalasia to those undergoing POEM as an initial therapy. ⋯ Per-oral endoscopic myotomy is a safe and effective treatment for achalasia which improves dysphagia and disease-specific quality of life. Previous endoscopic or laparoscopic treatment of achalasia does not affect the performance or early outcome of POEM.

Extralevator abdominoperineal resection had oncologic superiority with reduced local recurrence and improving survival rates. However, extended perineal resection resulted in complicated perineal reconstructions. Therefore, a new surgical technique to overcome previous limitations is required. This study aims to demonstrate a surgical procedure and outcomes of the modified extralevator abdominoperineal resection, which satisfies both an extended cylindrical resection and a convenient perineal wound closure by modification of the surgical dissection plane. ⋯ The modified extralevator abdominoperineal resection was feasible and safe for patients with low rectal cancer with extended perineal dissection and convenient direct wound closure.
