The majority of the data on PEGs has been obtained from case reports and retrospective studies. A review of data derived from six large series evaluating PEG placement through various methods showed that successful PEG placement was accomplished in 98 of cases. Procedure-related mortality was with aspiration and peritonitis accounting for 90 of cases. Mortality associated with the development of a major complication was 25 . Major complications were found in 1-4 of patients whereas minor complications were reported in 4-13 of cases. In another more recent review investigating data obtained from 1758 cases the reported major and minor complication rates were and 6 respectively 10 . The data on open gastrostomies have demonstrated a wide variation in the reported morbidity and mortality. In a review of the literature the reported major complication rate for open gastrostomies ranged from less than 2 to as high as 75 with minor complication rates of 0-13 11 . Major complications following PEG placement include aspiration perforation peritonitis premature gastrostomy tube removal tube migration gastrocolocutaneous fistula hemorrhage necrotizing fasciitis and tumor seeding of the PEG stoma. Minor complications are common and include peristomal wound infection inflammation and leakage around the gastrostomy tube granulation tissue formation tube occlusion and fragmentation and tube migration. Aspiration Pneumonia Aspiration pneumonia resulting from PEG .
