Risk factors of early mortality after percutaneous endoscopic gastrostomy: a retrospective study]

When performing percutaneous endoscopic gastrostomy (PEG), the associated risks must always be kept in mind. We investigated and analyzed early mortality after PEG, retrospectively. Of the 302 patients (63% males, mean age 75 years) who underwent PEG at our center from 1999 to 2008, 7 patients (2.3%) were dead within 30 days of the procedure. Only one death could be directly related to the procedure. By a logistic regression analysis, the following 3 factors were identified as independent preoperative risk factors for death within 30 days of the PEG: (1) high serum creatinine level [mg/dl, p=0.006, odds ratio (OR)=8.472]; (2) past history of ischemic heart disease [p=0.008, OR=9.985]; (3) low serum albumin level [g/dl, p=0.017, OR=0.096]. In patients with poor renal function, poor cardiac function, severe malnutrition or exhaustion, the indications for PEG need to be very carefully investigated.
