Identification of Bacterial and Fungal Pathogens in Patients with Post-Laparoscopic Sleeve Gastrectomy Leakage
Post-laparoscopic sleeve gastrectomy (LSG) leak leads to serious complications, and death may occur. The microbial pattern should be established in order to plan empirical antimicrobial therapy. The intra-abdominal leaks post-LSG were cultured and reviewed.
Microbial cultures collected from all post-sleeve leakage cases managed at the King Khalid University Hospital (KKUH) from May 2011 until April 2016 were reviewed.
A total of 31 patients with positive leak post-LSG were included. The mean presentation time was postoperative day 12. Computed tomography (CT) was done for all patients on presentation with CT-guided aspiration and drainage next day. Samples from the collection were aspirated first for culture then a pigtail drain was kept in place. The average time of drain removal was on the 75th postoperative day. A total of 28 patients (90.3%) had positive culture results. Candida species were the most common organism isolated from 19 patients (61.2%), among them, 10 (32.2%) were positive for Candida species only. Positive bacterial cultures were found in 18 patients (58%). Majority of which single bacterial pathogen isolate, only seven patients had two organisms, and four patients had three organisms. Klebsiella pneumoniae was the most frequent isolated bacteria [8 patients (44.4%)] followed by Streptococcus and Pseudomonas species. Candida albicans was the most common Candida species isolated, 13 patients (68.4%).
Fungal microbes isolated from post-LSG leak collection are common and could be considered in the primary empirical therapy. The antibiotic choice for the leak should cover Klebsiella, Streptococcus, and Pseudomonas until definitive culture results are obtained.
