The role of laparoscopy in patients with suspected peritonitis: experience of a single institution

PURPOSE: In this report, we retrospectively evaluate the effect of a laparoscopic approach in the diagnosis and treatment of acute abdominal pain in patients with suspected peritonitis. PATIENTS AND METHODS: We evaluated the clinical records of patients admitted to our institution between January 1995 and July 2001 with a diagnosis of acute abdomen and suspected peritonitis. RESULTS: Ninety four of 229 patients underwent diagnostic laparoscopy. In this series, 83 (88.3%) of the cases were successfully treated by emergent laparoscopy for an acute abdomen. Eleven (11.7%) required conversion to an open laparotomy procedure. Overall, the preoperative diagnosis was confirmed by laparoscopy in 67 (71.27%) of the cases. It was not confirmed in 27 (28.73%). Postoperative mortality was 4.25%. Morbidity was 8.5%. DISCUSSION: Data reported in the literature establish that laparoscopy offers adequate visualization of the entire abdomen and pelvic cavity in the diagnosis of an abdomen acute secondary to peritonitis. In this series, laparoscopy confirmed the diagnosis in 97.8% of the patients, and minimally invasive treatment was achieved in 88.3% of the cases. Female patients with gynecologic disease particularly benefitted from a laparoscopic approach, which permitted the correct evaluation of this condition and may have prevented unnecessary laparotomy. We believe that laparoscopy is an accurate modality for the diagnosis and treatment of patients with an acute abdomen and suspected peritonitis when the diagnosis cannot be clearly made by physical examination and noninvasive methods.
