Two schedules of antimicrobial agents were compared in this prospective study of antimicrobial prophylaxis in diabetes mellitus patients undergoing cholecystectomy for symptomatic cholelithiasis. One hundred women grouped into two matched groups of 50 women each were studied. The results suggest that apart from a population of patients with identifiable risks of complications, a 24 hour, four dose antimicrobial prophylaxis is adequate and more cost effective than the five day schedule for most patients.

Routine prophylactic antibiotics for patients undergoing biliary tract surgery in the presence of high risk factors (recent episode of acute cholecystitis, age greater than 60 years) is now well established [3,6]. Due to their increased risk of sepsis and other complications, diabetics undergoing cholecystectomy for symptomatic cholecystitis are candidates for antimicrobial prophylaxis [5,6]. Which antimicrobial agent, what dosage, and for how long, however, is not clear [6]. Because diabetes mellitus and chronic cholecystitis are common in our patient population, a clear antimicrobial prophylaxis policy for our diabetics undergoing cholecystectomy for symptomatic cholecystitis is important. This study attempts to fulfill that need.
Material and MethodsTwo schedules of antimicrobial prophylaxis for diabetics undergoing cholecystectomy for symptomatic cholecystitis were compared in this prospective study in Prince Abdulrahman Ibn Ahmed Al Sudery Central Hospital, Al Jouf, Saudi Arabia. A total of 100 women, ages 25 to 75 years, were admitted to the study. Of these, 60 (60%) patients had non-insulin dependent diabetes mellitus (NIDDM) while 40 (40%) had insulin-dependent diabetes mellitus (IDDM). All patients had clinical presentation consistent with chronic cholecystitis and ultrasound evidence of cholelithiasis. Excluded from the study were patients who had ultrasound evidence of choledocholithiasis, concurrent or history of jaundice, acalcular or emphysematous cholecystitis, and sensivity to cephalosporins. The patients were paired in terms of age, insulin dependence status, and body habitus (ectomorphic, mesomorphic, and endomorphic) to achieve two well matched groups of 50 patients each, designated Groups 1 and 2, which comprised the two arms of the study.All patients underwent cholecystectomy including intraoperative cholangiogram via a catheter passed through the cystic duct. All patients who were 80 kilograms or more in weight received 5,000 units of heparin on call to the operating room and q. 12 hourly postoperatively until fully ambulatory (usually 48 to 72 hours). Group 1 patients received 1 gram of cephradine intravenously on ca...
