Percutaneous endoscopic gastrostomy for decompression of malignant bowel obstruction

Abstract

Background Previous reports on percutaneous endoscopic gastrostomy (PEG) for bowel decompression have included a relatively small number of patients and the details of post-procedural outcomes and complications are lacking. The aim of the present study was to evaluate the outcomes and safety of PEG for bowel decompression in a relatively large number of patients with malignant bowel obstruction. Patients and Methods Over a 10-year period, 76 patients with malignant bowel obstruction were referred to the main referral cancer center in Shizuoka prefecture for PEG to obtain decompression. The method for gastrostomy was carried out by the pull-method, the modified introducer method and the percutaneous endoscopic gastrojejunostomy method. Patient demographics, procedural success, complications, elimination of nasal intubation, and survival were reviewed. Results Successful placement was achieved in 93% of patients (71/76). Procedure-related complications occurred in 21% ofpatients (15/71), of which the majority involved stomal leakage (eight patients), and wound infection (six patients). There were no procedure-related deaths. Among the 55 patients who required nasal intubation before PEG, a trans-gastrostomy intestinal tube was inserted in 16 patients. The need for further nasal intubation was eliminated in 96% of the patients (53/55). The median survival time was 63 days (range, 8-444 days) after PEG placement. Conclusions PEG for bowel decompression in patients with malignant obstruction can be carried out with an acceptable risk of minor complications. In combination with a trans-gastrostomy intestinal tube insertion, the elimination of nasal intubation can be achieved in most patients. © 2013 Japan Gastroenterological Endoscopy Society.
