Effect on negative laparoscopy rate in chronic pelvic pain patients using patient assisted laparoscopy.

Objective: To determine the value of Patient Assisted Laparoscopy (PAL) in the diagnosis of pelvic pain.

Methods: One hundred patients with pelvic pain were assessed by the procedure of Patient Assisted Laparoscopy to determine the cause of chronic pelvic pain.

Results: Of the 100 patients with pelvic pain, 12 patients were not assessed due to technique failure, which included reaction to the carbon dioxide gas, inadequate visualization due to abdominal adhesions or failure to enter peritoneum. Of the remaining 88 patients, 61 had endometriosis; 16 had adhesions not associated with endometriosis; five had hernias; one had occult bowel cancer; one pseudo-stone from previous cholecystectomy; one had pain as a result of staples used at hysterectomy and one patient had chronic Crohn's disease. Two patients had no demonstrated interabdominal cause for their symptoms.

Conclusion: In contrast to the well published rate of 35% negative laparoscopy in those patients with pelvic pain when examined under general anesthetic, Patient Assisted Laparoscopy decreased the negative laparoscopy rate to less than 3%. This methodology was also of benefit in giving the patient a better understanding of the cause of her pain and the need for therapy.
