Manejo conservador en diverticulitis aguda perforada con aire extraluminal

Background: The conservative management of perforated diverticulitis with extraluminal air (PDA) is controversial. In selected hospitalized patients may offer less morbidity and mortality and avoid an ostomy. Aim: To describe its clinical and imagenologic characteristics, the need for surgical procedure and morbimortality of patients with perforated diverticulitis with extraluminal air in conservative ma-nagement. Materials and Methods: Retrospective descriptive study of hemodynamically stable hospitalized patients with a PDA diagnosis without evidence of peritonitis during the years 2009 and 2015. Results: 162 patients were admitted with the diagnosis of acute diverticulitis. 53.1% of cases were acute complicated diverticulitis, 43% (37 cases) were PDA. The average age was 59.6 years and most of them women (54.1%). The most common clinical manifestations were abdominal pain (97.3%), peritoneal signs (59.5%) and fever (40.5%). The abdomen and pelvic computerized axial tomography scan showed extra-colonic bubbles in 78.4% and pneumoperitoneum in 21.6%. The conservative management was successful in 87.8% of cases. After a 71.2-month follow-up, the recurrence was 28.1% and 31.3% had an elective sigmoidectomy. 5 cases did not respond to medical treatment, one of them resulting in death. Conclusion: The conservative management of PDA is a valid treatment option with a high degree of success in the selected sample of hospitalized patients. The decision of having emergency surgery and elective sigmoidectomy post DPA should be evaluated individually.
