Efficacy of 48-hour post-operative antibiotics prophylaxis for patients undergoing percutaneous endoscopic gastrostomy tube in preventing site infection.

BACKGROUND

Percutaneous Endoscopic Gastrostomy (PEG) is an endoscopic procedure for placing a feeding tube into the stomach through the skin, primarily to avoid malnutrition. Malnutrition can increase the risk of wound infection, whose incidence can be decreased by using antibiotic prophylaxis.

AIM

The purpose of our study was to evaluate the efficacy of a new antibiotic regimen in preventing acute post-PEG procedure complications.

PATIENTS AND METHODS

Ninety-seven consecutive patients were put on combined antibiotic therapy of clindamycin 600 mg and cefotaxime 1,000 mg every eight hours, starting with the insertion of the PEG tube and maintained for 48 hours. Pain/tenderness, leakage/drainage, bleeding fever, maximum white blood cells (WBC) count, pus/discharge, and PEG tube function were evaluated within 48 hours and 1 week from PEG insertion.

RESULTS

Infection at the site of PEG insertion occurred in 3 cases (3.1%) within 48 hours and in 1 case (1.0%) within 7 days. Within 48 hours from the procedure, incidence of fever and increased WBC count was 10.3% and 9.3%, respectively, though at 7 days all were resolved. Pain, leak, and bleeding at the site of PEG placement were prevalently mild within 48 hours (74.2%, 12.4%,13.4% of patients, respectively) and subsided within 7 days (2.1%, 0%, 0%). One case (1.0%) of minor antibiotic side effect occurred. Two patients died due to complications not related to the procedure.

CONCLUSION

The combined use of short-term cefotaxime and clindamycin seems to be effective in reducing incidence of acute complications due to PEG placement without increasing side-effects.
