Emergency laparotomy at district hospitals in a developing nation: a review of indications and outcomes of treatment

Objective: Recently, emergency and essential surgical and anesthesia care at district hospitals is increasingly gaining recognition as a critical, though neglected element of health care system in Africa and other developing nations. Emergency laparotomy is a versatile procedure that can cure a great deal of acute abdominal conditions. The aim of this study was to document the indications and outcomes of laparotomy for emergency abdominal surgical conditions in our district hospitals.Methods: This retrospective study was undertaken in district hospitals from January ۲۰۰۹ to December ۲۰۱۸. Associations between different variables were measured and compared using statistical tests of significance.Results: Of the ۸۷۹ patients evaluated, appendicitis (n=۳۶۱, ۴۱.۱%) was the most frequent indication for emergency laparotomy followed by complicated external hernias (n=۱۲۰, ۱۳.۷%). Other indications were adhesive intestinal obstruction (n=۱۱۱, ۱۲.۶%), typhoid perforation (n=۹۸, ۱۱.۱%), perforated peptic ulcer (n=۸۹, ۱۰.۱%), trauma (n=۵۸, ۶.۶%), colorectal cancer (CRC) (n=۱۸, ۲.۰%) and others (n=۲۴, ۲.۸%). The vast majority of patients (n=۷۲۶, ۸۲.۶%) were presented after ۲۴ hours of the onset of disease. Approximately, one-third of patients (n=۲۷۸, ۳۱.۶%) had comorbidities, ۸۶۷ (۹۸.۶%) had high ASA scores (III and IV) and ۱۰۵ (۱۱.۹%) received intestinal resection with or without stoma. The main independent predictors of mortality were late presentation (P=۰.۰۰۳), generalized peritonitis (P=۰.۰۰۱), bowel resection (P=۰.۰۰۰) and high ASA (III and IV) scores (P=۰.۰۰۰). Overall, the mortality rate was ۱۰.۶%. The commonest complication was wound infection (۳۹.۷%), followed by intra-abdominal collection (۱۰.۰%).Conclusion: The most common indication for emergency laparotomy was appendicitis followed by complicated hernias. The major independent predictors of mortality included bowel resection, high ASA score, late presentation and generalized peritonitis.
