Factors Associated with Short-Term Surgical Outcomes Among Women Presenting with Pelvic Peritonitis at Bugando Medical Centre Mwanza, Tanzania.

Background: Pelvic peritonitis is a rarely reported pathological condition in literature and emergency laparotomies are a common surgical procedure performed for these conditions in developing countries. This study was designed to investigate factors that are associated with short-term surgical outcomes among women with pelvic peritonitis.

Methods: The study included retrospective and prospective data obtained between November 2021 and May 2022 from Bugando Medical Centre (BMC). Standardized data collection tool was used to capture clinical, surgical and laboratory data. Descriptive data analysis was done using STATA version 13.

Results: A total of 101 participants were recruited; 22 prospectively and 79 retrospectively. The median age was 29[Interquartile range (IQR) 24 to 35] years. Majority (76.2%) of participants were referred patients. Obstetric related peritonitis 82.2% (83/101) was the most frequently detected with a necrotic and or dehiscent lower uterine segment (LUS) that necessitated a subtotal abdominal hysterectomy (STAH) being the commonest (40.8%) intraoperative finding. Postoperative complications were reported in 36.7% (36/98) and were significantly associated with pulse rates >100b/min (P=.041) and platelets <150 × 10³ mm³ (P=.049). The median length of hospital stay was 19[IQR: 7 to 35] days and temperature >37.5°C (aOR=5.08, 95% CI 1.23-20.97, P=.025) independently predicted prolonged hospital stay. Death occurred in 9.2% of patients and having ASA score of 5 (P=.045) was associated with death. Multi-drug resistant (MDR) gram-negative bacteria (85.2%) were the predominant pathogens causing pelvic peritonitis.

Conclusion: A significant proportion of patients with pelvic peritonitis and deranged sepsis markers develop short-term surgical complications with a significant number of those with fever stay more than 14 days. There is a need of timely complete sepsis work up of the patients with pelvic peritonitis to ensure appropriate management is instituted to prevent associated morbidity and mortality.
