title: Differences in the morbidity of radical hysterectomy between gynecological oncologists.
abstract: A multivariate analysis was performed on 405 patients who underwent radical hysterectomy and pelvic lymphadenectomy by eight surgeons for stage IB cervical carcinoma, to determine the influence of primary surgeon on morbidity. Patient characteristics analyzed (mean/proportion) were age (41 years), quetelet index (25.4), American Society of Anesthesiologists classification of physical status (0.5% > 2), previous laparotomies (23%), previous radiation (0.7%), prophylactic antibiotics (95%), prophylactic heparin (67%), tumor size (1.0 cm), histology (68% SCC), grade (68% grades 2 or 3), vascular space involvement (45%), pelvic lymph node metastases (6%), and depth of invasion (6.6 mm). Morbidity characteristics analyzed (mean/proportion) were blood loss (910 ml), operative time (3.0 hr), intra-op complications (5%), post-op infectious (21%) and non-infectious complications (7%), transfusions (35%), post-op hospital stay (9.9 days), time to normal urine residual (9.0 days), and bladder dysfunction at 3 months post-op (21%). Mean tumor size was the only preoperative characteristic that was significantly different among surgeons (P < 0.001). Of the factors evaluated for morbidity, mean blood loss (P < 0.0001), operative time (P < 0.001), and postoperative hospital stay (P < 0.001) varied among physicians as did the incidence of blood transfusion (P < 0.0001) and bladder dysfunction at 3 months postoperatively (P < 0.0001). On multivariate analysis, surgeon was independently significant for blood loss (P < 0.0001), operative time (P < 0.0001), postoperative hospital stay (P < 0.001), incidence of blood transfusion (P < 0.0001), and bladder dysfunction at 3 months postoperatively (P < 0.0001). Despite differences in tumor size, patients appeared similar among the surgeons. Differences in patient morbidity among surgeons do exist and are of significant magnitude. Since the design of surgical trials to assess the therapeutic ratio should include not only measures of efficacy, but also measures of morbidity to be meaningful, intersurgical morbidity between centers/surgeons must continue to be quantified.
