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.

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.

Obstructive symptoms are common in advanced malignancies. Venting percutaneous endoscopic gastrostomy (VPEG) tubes can be placed for palliation. The aim of this study was to determine the outcomes of VPEG placement in patients with advanced malignancy. ⋯ VPEG tubes can be safely placed in patients with obstructive symptoms due to inoperable malignancy, with complete relief in the majority of patients. Ascites was a risk factor for post-procedural infectious AEs. Drainage of ascites prior to VPEG tube placement may decrease this risk, although this requires further study.
