Purpose:
Although laparoscopic pyloromyotomy is considered to be a clean case, many surgeons administer prophylactic preoperative antibiotics. The aim of this study was to evaluate the impact of prophylactic antibiotics on the wound infection rate after laparoscopic pyloromyotomy.
Methods:
We conducted a retrospective review of all patients who underwent laparoscopic pyloromyotomy at our institution between August 2002 and December 2009. Data included patient age, sex, weight, serum HCO(3) at admission and at operation, and if the patient received prophylactic antibiotics. The rate of wound infection or other wound complications, including suture granuloma, umbilical granuloma, umbilical hernia, skin dehiscence, and omental evisceration, was determined.
Results:
Two hundred ninety-nine patients underwent 301 consecutive laparoscopic pyloromyotomies. Sixty-four percent (n = 194) of patients returned for follow-up and were included in the study. Fifty-seven percent (group A, n = 111) received antibiotics, and 43% (group B, n = 84) did not. There were 3 wound infections in each of the equally matched groups (group A, 2.7%; group B, 3.5%; P = .73). Other wound complications occurred in 4.5% of patients (n = 5) in group A and 8.3% of patients (n = 7) in group B (P = .27).
Conclusion:
The use of prophylactic antibiotics does not significantly decrease the rate of wound infection or other wound complications after laparoscopic pyloromyotomy.
Insights
Prophylactic antibiotics did not significantly reduce wound infections or complications in laparoscopic pyloromyotomy patients. This study suggests routine antibiotic use may not be necessary for this clean surgical procedure.
Area of Science:
- Pediatric Surgery
- Surgical Infection Prevention
Background:
- Laparoscopic pyloromyotomy is generally classified as a clean surgical procedure.
- Despite its classification, prophylactic antibiotics are frequently administered preoperatively by surgeons.
Purpose of the Study:
- To assess the effect of prophylactic antibiotics on the incidence of wound infections following laparoscopic pyloromyotomy.
- To determine if routine antibiotic prophylaxis impacts other wound complication rates in this patient population.
Main Methods:
- Retrospective chart review of patients undergoing laparoscopic pyloromyotomy from August 2002 to December 2009.
- Data collected included patient demographics, serum bicarbonate levels, and antibiotic administration status.
- Wound infection and complication rates were compared between patients who received antibiotics and those who did not.
Main Results:
- A total of 301 laparoscopic pylorotomies were analyzed, with 194 patients included in the follow-up study.
- The wound infection rate was 2.7% in the antibiotic group (n=111) and 3.5% in the no-antibiotic group (n=84), with no statistically significant difference (P = .73).
- Other wound complications occurred in 4.5% of the antibiotic group versus 8.3% of the no-antibiotic group (P = .27).
Conclusions:
- Prophylactic antibiotic use does not significantly lower the risk of wound infection after laparoscopic pyloromyotomy.
- The study indicates that routine preoperative antibiotics may not be beneficial in preventing wound complications for this procedure.
