Emergency Laparoscopic Management of Perforative Peritonitis: A Retrospective Study

Background Peritonitis was previously considered a contraindication for minimally invasive surgery due to the risk of malignant hypercapnia partial pressure of carbon-dioxide (PCO2) and toxic shock syndrome. The objective of this retrospective study was to evaluate the role of laparoscopic surgery (LS) in selected patients with perforative peritonitis and to study its feasibility, safety, and outcomes. Patients and methods This was a retrospective study of 25 patients spanning over five years from 2015 to 2020. This study comprised all patients who were diagnosed with perforative peritonitis on preoperative physical/clinical examination, radiological evaluations, and who were stable enough to withstand pneumoperitoneum. Patients were evaluated for causes, operative time, duration of hospital stay, intra-, and postoperative complications, time taken to resume normal activity, and conversion to open surgery. Data was extracted from the hospital electronic medical records, for the above-mentioned parameters. Results Twenty-five patients with perforative peritonitis underwent diagnostic and therapeutic LS in our institute. The mean age was 46 years (35-79 years). Ten patients (40%) were diagnosed with gastro-duodenal perforation. Out of these ten patients, ninepatients (90%) were managed totally laparoscopically, while one patient (10%) required conversion to open surgery. There were 15 patients (60%) with small bowel perforation. Thirteen of the 15 patients were managed laparoscopically, with the remaining two requiring conversion to open surgery. The average time taken for the procedure was 90 minutes. The mean time to initiate the postoperative peroral liquid diet was 3.4 days. The mean postoperative stay was 6.9 days. The time taken to resume normal activity was 10-12 days. Conclusions Laparoscopic management is feasible and safe for patients with perforative peritonitis. Careful patient selection and the surgeon's experience with the procedure are critical determinants of success.
