BackgroundThe diagnosis of acute abdominal conditions in the critically ill patient remains difficult. The goal of this study is to demonstrate the use of bedside minilaparoscopy as a diagnostic aid in the intensive care unit (ICU) in patients with possible intra-abdominal catastrophic condition.MethodsBetween February 1998 and May 1999, intensive care patients with abdominal pain, unexplained acidosis or sepsis, or suspected mesenteric ischemia were eligible for bedside diagnostic minilaparoscopy (3.3-mm laparoscope and instruments). The procedure was performed at bedside in the ICU with the patient under local anesthesia and intravenous sedation. Pneumoperitoneum was established with nitrous oxide (N(2)O) to a pressure of 8 to 10 mm Hg. Hemodynamics and ventilatory parameters were monitored before, during, and after the procedure.ResultsNineteen patients underwent bedside diagnostic minilaparoscopy, including 1 patient who underwent 2 diagnostic laparoscopies. Total procedure time was 9 to 68 minutes (mean, 21 minutes). Three patients were found to have extensive mesenteric ischemia and did not undergo laparotomy. One patient found to have questionably viable bowel at laparoscopy underwent a nontherapeutic formal laparotomy. One patient had a gangrenous gallbladder, and another had a small ischemic segment of bowel; each underwent later open laparotomy and resection. The remaining laparoscopic examinations either showed a nonsurgical cause for the patient's condition or were normal. Nontherapeutic laparotomy was avoided in 19 of 20 patients. One gallbladder perforation occurred during laparoscopy in a patient with a necrotic gallbladder.ConclusionsBedside minilaparoscopy can be a safe and accurate method to evaluate critically ill patients in whom the possibility of mesenteric ischemia or other intra-abdominal process is entertained. Nontherapeutic laparotomy can be avoided in many critically ill patients. Bedside diagnostic laparoscopy can be a useful replacement for diagnostic laparotomy in the operating room. It should be included in the diagnostic algorithm in the evaluation of the unstable patient in the ICU with a suspected acute intra-abdominal process.
