Filter by:Undetected bowel perforation is a rare but dangerous complication of laparoscopic surgery. If the injury is not detected and treated at the time of the surgical procedure, the patient can suffer severe complications, including septic shock and eventually death. The investigator's goal is to test a novel device that can detect bowel gas leakage from perforation and alert the surgeon during the operation by evaluating the gases present in the insufflated abdomen during surgery. This study will determine the ability of the device to be attached to a standard trocar during the operation and periodically draw small samples or aliquots of gas from the abdomen to evaluate the gas and accurately detect gaseous content from the bowel. Before the device can be used to detect bowel perforations, the investigators must first ensure that it can accurately detect bowel gas in an insufflated abdomen.
The investigators hypothesize that an increase in dietary fiber intake during radiation therapy may provide better long-term intestinal health for the cancer survivor. If the hypothesis is not correct, the increased intake may only mean an increase in acute side effects. All participants are advised to consume at least 16 g of dietary fiber/day via food. In addition, participants are invited to take capsules that together contain either 5.5 g of dietary fiber from psyllium husk or placebo.
