Surgical Excision of Advanced Endometriosis: Perioperative Outcomes and Impacting Factors.

OBJECTIVE: To determine perioperative outcomes and factors impacting operating time, length of hospital stay, and complications of patients undergoing surgery for stage 3 or 4 endometriosis. DESIGN: Retrospective review of medical records (Canadian Task Force classification II-2). SETTING: Mayo Clinic Hospital, Phoenix, Arizona. PATIENTS: Women (n = 493) with endometriosis stage 3 and 4 undergoing surgical excision between March 15, 2005, and December 31, 2011. INTERVENTIONS: Robotic-assisted (n = 331) or laparoscopic (n = 162) excision. MEASUREMENTS: Age, body mass index, comorbidities, number and type of procedures per patient, type of surgical approach, operating time, blood loss, intraoperative and postoperative complications (within 42 days), and length of hospital stay. MAIN RESULTS: The mean patient age was 39.5 years; body mass index, 25.9; number of procedures, 3.3; operating time, 130.4 minutes; blood loss, 88.5 mL; and hospital stay, 1.0 days. Major complications occurred in 5 patients (1.5%). Fifty-nine patients (12.0%) underwent modified radical hysterectomy, 90 (18.3%) underwent ureteral and/or intestinal resection, and 3 (0.6%) underwent diaphragm resection. Factors significantly associated with operating time included age (p = .008) and blood loss, number of procedures per patient, and robotics (all p < .001). Length of stay was affected by age, operating time, and blood loss (all p < .001). Operating time was the only significant factor associated with postoperative complications (p < .001). CONCLUSION: Operating time is an independent and significant factor for postoperative complications and hospital stay.

Analysis of secondary cytoreduction for recurrent ovarian cancer by robotics, laparoscopy and laparotomy.

OBJECTIVE: Analysis of perioperative outcomes and survival of patients with recurrent ovarian cancer undergoing secondary cytoreduction by robotics, laparoscopy, or laparotomy. METHODS: Retrospective analysis of 52 selected patients with recurrent ovarian cancer undergoing secondary cytoreduction by laparoscopy (9), laparotomy (33) or robotics (10) between January 2006 and December 2010. Comparison was made by a total of 21 factors including age, BMI, number of previous surgeries, tumor type and grade, number of procedures, and 15 types of procedures performed at secondary cytoreduction. RESULTS: For all patients, the mean operating time was 213.8 min, mean blood loss 657.4 ml; and mean hospital stay 7.5 days. Complete debulking was achieved in 75% of patients. Postoperative complications were noted in 36.5% of patients. Overall and progression-free survival at 3-years were 58.8% and 34.1%, respectively. Laparoscopy and robotics had reduced blood loss and hospital stay, while no differences were observed among the three groups for operating time, complications, complete debulking, and survival. CONCLUSION: Selected patients with recurrent ovarian cancer benefit from a laparoscopic or robotic secondary cytoreduction without compromising survival. Robotics and laparoscopy provide similar perioperative outcomes, and reduced blood loss and shorter hospital stay as compared to laparotomy. Laparotomy seems preferable for patients with widespread peritoneal implants, multiple sites of recurrence, and/or extensive adhesions.
