Feasibility of No Prophylactic Antibiotics Use in Patients Undergoing Total Laparoscopic Distal Gastrectomy for Gastric Carcinoma: A Propensity Score-Matched Case-Control Study


Feasibility of No Prophylactic Antibiotics Use in Patients Undergoing Total Laparoscopic Distal Gastrectomy for Gastric Carcinoma: A Propensity Score-Matched Case-Control Study

Yongmin Na et al. J Gastric Cancer.


Purpose: Laparoscopic surgery is associated with lower surgical site infection (SSI) rates due to minimal skin incision and non-exposure of visceral organs. Most previous studies have analyzed the efficacy of prophylactic antibiotic use in open surgery. Here, we investigated the feasibility of total laparoscopic distal gastrectomy (TLDG) for gastric carcinoma without prophylactic antibiotic use.

Materials and methods: Seventy-one patients who underwent TLDG without prophylactic antibiotic use were 1:1 propensity score matched with 393 patients who underwent TLDG with antibiotic prophylaxis. The short-term surgical outcomes, including SSI rates, were compared between the groups.

Results: After matching, 65 patients were selected in each group. The baseline clinicopathological characteristics were well balanced in the matched sample. In the matched group, there was no significant increase in postoperative morbidity in the non-prophylactic group compared with the prophylactic group (18.5% vs. 15.4%, P=0.640), and there were no grade 3≤ complications (1.4% vs. 0%, respectively; P=1.000). The SSI rates in the non-prophylactic and prophylactic groups were 3.1% and 1.5%, respectively (P=0.559). The time to gas passage, diet initiation, and mean hospital stay were not significantly different between the 2 groups. The SSI rate did not increase in the non-prophylactic group in the different subgroups based on different clinicopathological characteristics.

Conclusions: Postoperative morbidity, including SSI rates, did not significantly increase in patients undergoing TLDG without prophylactic antibiotic use. A large prospective randomized trial is warranted to reappraise the efficacy of prophylactic antibiotic use in patients undergoing TLDG.
