Abstract

OBJECTIVE: Compare the effectiveness of 1st-3rd generation cephalosporins (1st-3rdCE) to broad-spectrum antibiotics in decreasing surgical site infections (SSI) after pancreatectomy.

SUMMARY OF BACKGROUND DATA: SSI is one of the most common complications after pancreatic surgery. Various antibiotic regimens are utilized nationwide with no clear guidelines for pancreatectomy. As we await results of a recently initiated prospective trial, this study retrospectively evaluates over 15,000 patients using the same administrative data abstraction tools as in the trial.

METHODS: All relevant clinical variables were collected from the 2016-2018 targeted-pancreatectomy database from the American College of Surgeon National Surgical Quality Improvement Program. Preoperative antibiotics were initially collected as first-generation cephalosporin, second or third-generation cephalosporin, and broad-spectrum antibiotics (Broad-abx).

RESULTS: Of the 15,182 patients who completed a pancreatic surgery between 2016 and 2018, 6114 (40%) received a first-generation cephalosporin, 4097 (27%) received a second or third-generation cephalosporin, and 4971 (33%) received Broad-abx. On multivariate analysis, Broad-abx was associated with a decrease in all-type SSI compared to 1st-3rdCE (odds ratio = 0.73-0.77, P < 0.001) after open pancreaticoduodenectomy (PD). There was no difference in SSI between antibiotic-types after distal pancreatectomy. Subgroup multivariate analysis of open PD revealed decrease in all-type SSI with Broad-abx amongst patients with jaundice and/or biliary stent only, regardless of wound protector use (odds ratio = 0.69-0.70, P < 0.001). Propensity score matching of open PD patients with jaundice and/or biliary stent confirmed a decrease in all-type SSI (19% vs 24%, P = 0.001), and organ-space SSI (12% vs 16%, P < 0.001).

CONCLUSION: Broad-abx are associated with decreased SSI after open PD and may be preferred specifically for patients with preoperative biliary stent and/or jaundice.
