A randomized control trial to determine the need for postoperative antibiotics after laparoscopic appendicectomy in nonperforated appendicitis

Abstract

Background: Acute Appendicitis is the most common cause of acute pain in the abdomen. Appropriate use of prophylactic antibiotics prevents the risk of postoperative surgical site infections (SSIs). However, there is no conclusive guideline concerning the duration of antibiotic usage. A single preoperative prophylactic dose has been recommended by many randomized control trials. Hence, the study aimed to determine the need for postoperative antibiotics after laparoscopic appendicectomy for nonperforated appendicitis.Methods: A total of 100 patients with nonperforated appendicitis undergoing laparoscopic appendicectomy divided into two groups. Group A (n=50) patients received single dose of preoperative antibiotic and group B (n=50) patients received preoperative dose, as well as three postoperative doses of antibiotics. Routine investigations including complete blood count, blood urea, serum creatinine; other investigations such as ultrasound of abdomen were also performed. Following laparoscopic appendicectomy, surgical wound was inspected after 48 h, 72 h, and on day 7 to look for any signs of postoperative SSI.Results: The mean age in group A was 30.74±10.69 years compared to 30.72±9.56 years (p=0.757) in group B. All the patients in study presented with right iliac fossa pain. Three patients in group A (6%) and two patients in group B (4%) had grade III SSIs, which were managed conservatively. The difference between both the groups for incidence of SSIs was statistically insignificant (p=1.000).Conclusions: Prophylactic postoperative doses of antibiotics confer no additional benefit over a single preoperative dose in preventing the postoperative SSIs after laparoscopic appendicectomy.

“…For this, Southampton Wound Assessment Scale can be used to evaluate and score the wound. 9 This scale enables surgical wound healing to be graded according to a defined criterion by giving every wound a numerical value and a more objective assessment. This wound grading system is shown in the Table-I.…”
