Laparoscopy in chronic abdominal pain: a prospective nonrandomized long-term follow-up study

Abstract

Goal: Our aim was to assess the long-term efficacy of diagnostic laparoscopy and adhesiolysis on the treatment of intractable chronic abdominal pain.

Study: This was a prospective nonrandomized study of 72 patients (60 women and 12 men). One surgeon performed a total of 79 diagnostic laparoscopies including 61 adhesiolysis. The patients' demographic data, operative findings, and long-term postoperative course were carefully recorded. A quality-of-life questionnaire was mailed after the mean follow-up of 3.7 years to find out the late course of any chronic abdominal symptoms after the surgery.

Results: Intra-abdominal adhesions were found in 61 patients (85%) in the laparoscopy, gynecologic disorders in 4, chronic appendicitis in 1, and no abnormality in 6 patients. The abdominal wall pain was a likely reason for pain in 12 patients (17%). The complication rate was minimal, including only four bleedings (one major), one perforation of urinary bladder, and three wound infections. At 1-month control, 38% of the patients were completely free of pain. In the long-term follow-up, chronic abdominal pain was totally healed in 33%, diminished in 46%, and unchanged in 21% of the patients. A total of 65 patients (90%) reported that the surgery had been beneficial for their intractable pain.

Conclusions: By careful selection, for patients with chronic abdominal pain, laparoscopy alleviates the symptoms in more than 70% of the patients, and it should be considered if other diagnostics tests are negative. A placebo-controlled study is needed, in which the patients are randomized into laparoscopy and conservatively treated groups with a quality-of-life measurement.
