title: Management of ovarian cysts in women undergoing restorative proctocolectomy for ulcerative colitis.
abstract: More than half of all patients undergoing restorative proctocolectomy (RP) for ulcerative colitis (UC) are women, yet there is a paucity of information regarding the frequency, management, and outcome of ovarian cysts. A single surgeon's (E.W.F.) experience with female patients (N = 165) who underwent RP for UC at an academic medical center was retrospectively evaluated for postoperative complications and overall outcome. Patients with large ovarian cysts (LOCs), defined as being greater than 5 cm in diameter, were further segregated for subanalysis. All results were analyzed using the Student's t test and Fisher's exact test. Patients were 29.3 +/- 13 years (mean) at the time of RP; 34 patients were less than 16 years old (21%), 113 patients (68%) were between the ages of 17 and 46 years, and 18 patients were over 46 years old (11%). All patients underwent total colectomy, mucosal proctectomy ileal pouch-anal anastomosis, and temporary end ileostomy. The ileostomy was closed 3 months later. Fifty-five of the 165 patients had ovarian cysts (33%) identified at operation, 46 had unilateral cysts, and nine had bilateral cysts. Mean ovarian cyst size was 4.6 +/- 2.7 cm (range <1-13 cm); 14 were LOCs. Patients with cysts <3 cm in diameter at operation were treated by observation with hormonal manipulation. Seventeen patients with cysts 3 to 5 cm in diameter required partial resection of one or both ovaries. Six of 14 patients with LOC underwent unilateral oophorectomy (cyst size range 10-13 cm). Twelve patients presented within 3 years after RP with malfunction of the pouch because of adhesions or minimal and uncontrolled passage of fecal material (soiling), partial obstruction due to LOC compression of the ileoanal pouch (n = 6), or adhesions. When evaluated on the basis of ovarian cyst size those without cysts and those with small cysts were significantly more likely to have children than those with LOC: 54 of 110 patients without cysts (49%), 18 of the 41 with cysts less than 5 cm in diameter (44%), and two of the 14 patients with LOC (14%) have had children (P = 0.047). Ovarian cysts are common in women undergoing RP for UC. Ovarian cysts often complicate postoperative intestinal function and are best treated by cyst resection or oophorectomy at the time of RP or ileostomy closure. Cysts under 3 cm in diameter may often be managed conservatively with few complications. Women with LOC after RP for UC have decreased fertility compared with those without cysts.
