In recent decades, a combination of cytoreductive surgery and intraperitoneal chemotherapy has yielded improvements in the survival of patients with peritoneal carcinomatosis. Laparoscopic cytoreductive surgery and intraperitoneal chemotherapy comprise a challenging and rarely reported surgical procedure. ⋯ Laparoscopic cytoreductive surgery and early postoperative intraperitoneal chemotherapy can be performed safely for selected patients with peritoneal carcinomatosis from colorectal cancer to a limited extent. Further studies with longer follow-up periods and larger numbers of patients are warranted to confirm the study findings.

Cystogastrostomy is commonly performed for internal drainage of pancreatic pseudocysts (PP) and concomitant debridement of walled-off pancreatic necrosis (WOPN). While an open approach to cystogastrostomy is well established, an optimal minimally invasive technique continues to evolve. This laparoscopic transgastric endolumenal cystogastrostomy presented here allows for a large cystogastrostomy with complete debridement of necrosis and internal drainage through a minimally invasive approach. ⋯ This technique of internal drainage via Lap-TEC and pancreatic debridement has been successful in achieving primary drainage and relieving symptoms of PP/WOPN with no mortality and minimal morbidity.

Cancer is one of the most common causes of death among morbidly obese individuals. Obese individuals have a well-documented increased risk of colon cancer. No guidelines are available for the workup of bariatric surgery patients in relation to colon cancer. ⋯ The risk for the development of colonic adenomatous polyps and cancer is high among young obese individuals in the Middle East. Guidelines are needed to establish criteria for screening in this group of individuals.

Endoscopic submucosal dissection (ESD) for the treatment of esophageal mucosal lesions has a risk of resection margin residues. The related risk factors and prognosis of post-ESD resection margin residues have not been fully evaluated. The aim of this study was to investigate the associated risk factors and the prognostic impact of resection margin residues after ESD of superficial esophageal squamous cell neoplasia. ⋯ The maximum diameter of the resected specimens and the depth of tumor invasion are risk factors for post-ESD positive resection margins, which suggests that larger lesions and a greater depth of invasion increases the chance of residual tumor after ESD.
