Percutaneous endoscopic gastrostomy (PEG) in cancer patients.

Ninety-nine cancer patients underwent PEG placement attempt at Rosewell Park Cancer Institute between January 1, 1985, and December 1, 1987. Ninety-eight of these were successful and were retrospectively reviewed to determine if cancer patients constitute a high-risk group for PEG placement. Procedure-related mortality was 2% and morbidity was 19%. Morbidity of 17% was noted at less than 30 days and 2% had late complications. Six complications were considered serious with peritonitis in 3 and tube loss in 3 patients; an additional 4 patients had a failure of adequate GI tract decompression which was the indication for their PEG placement. Ascites was a major factor in morbidity with 4 of 5 patients with ascites having complications including the 2 deaths. Overall major morbidity was not increased in cancer patients without ascites including a group of patients with carcinomatosis (18 patients) and 22 patients requiring preoperative dilatation and/or tumor ablative procedures. We conclude that morbidity in cancer patients is not increased if one excludes those with ascites from the procedure.
