Perioperative complications arising after transvaginal oocyte retrieval.

OBJECTIVE: To determine the incidence of perioperative morbidity in patients undergoing transvaginal oocyte retrieval and to identify those patients at greatest risk for complications. METHODS: A retrospective analysis was performed on 674 patients of reproductive age who underwent transvaginal retrieval of oocytes for assisted reproduction technologies during a 3-year period. All procedures were performed by surgeons with extensive experience with transvaginal retrieval. Patients were entered into the program with a primary diagnosis of unexplained infertility (16%), endometriosis (32%), pelvic adhesions and/or tubal occlusion (38%), or infertility from male or immunologic factors (14%). RESULTS: Of the 674 patients studied, ten (1.5%) required hospital admission because of perioperative complications. Nine of these patients needed intravenous antibiotics and one required admission and observation for an expanding broad-ligament hematoma. Six of nine women admitted for antibiotic therapy had a history of extensive pelvic adhesions with or without a history of salpingitis. Five of nine patients had a history of salpingitis. In addition, two patients experienced impressive vaginal arterial bleeding during the procedure. CONCLUSION: This study suggests that transvaginal retrieval may not be as innocuous as is often expressed and that the primary factor predisposing to perioperative morbidity is a history of previous pelvic inflammatory disease and/or adnexal adhesions.
