Overall cohort of patients undergoing gastric outlet obstruction. The overall cohorts comprised patients with pancreatic, cholangiocellular, gastric, intestinal, colorectal, renal cell, transitional cell, and mammarian carcinoma as well as ovarian cancer. Surgical gastrojejunostomy instead of curative surgery was considered in cases with technically non-resectable cancer (pancreatic, cholangiocellular, intestinal, colorectal, and renal cell carcinoma), distant metastases (pancreatic, cholangiocellular, gastric, and colorectal carcinoma and ovarian cancer), peritoneal carcinomatosis presenting with a high PCI in tumor entities qualifying for cytoreductive surgery and HIPEC (gastric, intestinal, and colorectal carcinoma) as well as cases presenting with peritoneal carcinomatosis tumor entities which preclude curative surgery (pancreatic, cholangiocellular, renal cell, transitional cell, and mammarian carcinoma). HIPEC, hyperthermic intraperitoneal chemotherapy; PCI, peritoneal carcinomatosis index
