Escherichia coli Infection Risk Following Sleeve Gastrectomy

Abstract* Backgruond Extremely obese patients can benefit greatly from sleeve gastrectomy, a very common and successful therapeutic procedure that is usually carried out via laparoscopy. A SG involves the excision of about eighty percent of the stomach. Beyond the possibility of significant weight loss, there are drawbacks to the SG procedure. A patient's may be susceptible to postoperative infection from gram-negative bacteria ( E. coli ). Method A study carried out at academic hospital center. It included 80 patients had sleeve gastrectomy for the study from ages above 25 year visiting the gastrointestinal tract hospital surgical unit between the first of Jan and the end of December 2024. It acquired data regarding the sociodemographic traits and the microbiological examinations conducted both prior to and following surgery, Qualitative data were presented as number and percentage, frequency distribution tables and All analyses were conducted at a significance value E. coli. E. coli was the most prevalent microbe (67%) that was isolated from patients, and fimH was the most virulent factor gene, followed by pap, Afa, and aer. Conclusion The results showed a percentage of (18.7%) of extraintestinal E. coli infection among patients with sleeve gastrectomy and most of cases were females (22.91%). E. coli showed high resistance towards amoxicillin, cefoxitin but sensitive to norfloxacin and ampicillin/sulbactam. The most virulence factor found from isolate was famH.
