Bowel preparation before microvascular free colon transfer for head and neck reconstruction: Is it necessary?

Mechanical bowel preparation before an), intestinal operation, especially when the large intestine is involved is routine practice for most surgeons. This practice has been questioned by many colorectal surgeons, With convincing data showing the lack of benefit of preoperative mechanical bowel preparation. Free microvascular transfer of the large intestine is occasionally, performed for reconstruction of the upper esophagus, as it. provides a better size match for the oropharynx than other visceral organs. Nine patients Underwent reconstruction of the cervical esophagus and voice tube using a segment of ileocolon. In all patients, the cervical esophagns was reconstruction Using the ascending colon and the voice tube was reconstructed using the ileal segment. Both were transferred as one free flap. All patients underwent the procedure without any form of preoperative mechanical bowel preparation. The patients were able to tolerate a solid diet at the end of the mean follow-up period of 7 months, and all esophagograms showed no evidence of stricture formation. One patient developed a fistula at, the recipient site that was treated with a regional flap, one patient developed a superficial wound infection of the abdominal wall, and one patient developed a postoperative abdominal wound dehiscence after several episodes of excessive coughing. Microvascular transfer of a large intestinal segment without preoperative mechanical bowel preparation for the reconstruction of the esophaus is a safe procedure. It can avoid the discomfort and complications associated with mechanical bowel preparation. If preoperative mechanical bowel preparation is preferred, the result of this study, which are based on nine patients, demonstrate the safety of this practice in cases where the patient did not follow proper instructions or in cases where the Use of the colon was not anticipated preoperatively.
