Utility of laparoscopy in chronic abdominal pain.
BACKGROUND
Patients with chronic abdominal pain can undergo numerous diagnostic tests with little change in their pain. This study was undertaken to assess the utility of performing diagnostic and therapeutic laparoscopy in patients with chronic abdominal pain for longer than 12 weeks.


METHODS
All patients undergoing laparoscopy by the primary author were prospectively entered into a database for the 3-year period July 1, 1997 through June 30, 2000. The patients' demographic data, length of time with pain, number of diagnostic studies performed before surgery, intraoperative findings, interventions, pathology, and long-term follow-up were determined.


RESULTS
A total of 70 patients (61 women and 9 men) with an average age of 42 years, underwent diagnostic laparoscopy only for the evaluation and treatment of chronic abdominal pain. The average length of time with pain was 74 weeks (range 12-260) and the average number of studies performed prior to surgical referral was 3.3. Fifty-three (76%) patients had their procedures performed as outpatients, with the remainder admitted for observation status. The average length of operative time was 70 minutes; no cases required conversion to an open procedure and no complications occurred. Findings included adhesions in 39, a hernia in 13, adhesions from the appendix to adjacent structures in 6, appendiceal pathology in 5, endometriosis in 3, and gallbladder pathology in 2. Ten patients had no obvious pathology. At the time of their initial postoperative visit, 90% reported their pain to be gone or improved. After an average follow-up of 129 weeks, 71.4% had long-term pain relief. All patients with recurrence of pain had it within the first 6 months. No patient experienced any long-term complications and all reported satisfaction with their procedure.


CONCLUSIONS
Laparoscopy has a significant diagnostic and therapeutic role in patients with chronic pain. Therapeutic laparoscopy studies have to follow-up with patients at least 6 months. With aggressive indicated therapeutic laparoscopy, including adhesiolysis, appendectomy, cholecystectomy, or hernia repairs, more than 70% of patients can have improvement in their pain.
