Laparoendoscopic single-site (LESS) surgery in patients with benign adnexal disease.
ABSTRACT To present our initial experience in laparoscopic surgery for benign adnexal disease performed exclusively through an umbilical incision using a single three-channel port and flexible laparoscopic instrumentation.
Tertiary-care referral center.
Since November, 2008, we have performed single-port laparoscopic surgery in nine patients diagnosed with benign adnexal disease. Patients with adnexal masses or endometriosis and a body mass index of <35 kg/m(2) were selected.
Laparoendoscopic single-site (LESS) surgery. In each case, a multichannel port was inserted into the peritoneum through a 1.5-2.0-centimeter umbilical incision.
Feasibility, postoperative pain score, age, BMI, estimated blood loss.
Eight of nine cases were completed successfully, without conversion to a standard laparoscopic approach or to laparotomy. An additional 3 mm extraumbilical port was required in one patient with stage 4 endometriosis. Seven out of nine patients had earlier abdominal surgery. The operative blood loss ranged from minimal to 75 mL. Duration of hospital stay was <24 hours in all cases. Minimal use of postoperative narcotics was required, and no intraoperative complications occurred.
The LESS surgery for benign adnexal disease is feasible in patients with or without earlier surgery. Additional investigation is needed to evaluate the safety and long-term outcomes of this new approach.

ABSTRACT: To compare the operative outcomes, postoperative pain, and subsequent convalescence after laparoendoscopic single-site surgery (LESS) or conventional laparoscopic surgery for adnexal preservation. From December 2009 to September 2010, 63 patients underwent LESS (n = 33) or a conventional laparoscopic surgery (n = 30) for cyst enucleation. The overall operative outcomes including postoperative pain measurement using the visual analog scale (VAS) were evaluated (time points 6, 24, and 24 hours). The convalescence data included data obtained from questionnaires on the need for analgesics and on patient-reported time to recovery end points. The preoperative characteristics did not significantly differ between the two groups. The postoperative hemoglobin drop was higher in the LESS group than in the conventional laparoscopic surgery group (P = 0.048). Postoperative pain at each VAS time point, oral analgesic requirement, intramuscular analgesic requirement, and the number of days until return to work were similar in both groups. In adnexa-preserving surgery performed in reproductive-age women, the operative outcomes, including satisfaction of the patients and convalescence after surgery, are comparable for LESS and conventional laparoscopy. LESS may be a feasible and a promising alternative method for scarless abdominal surgery in the treatment of young women with adnexal cysts.International Journal of Women's Health 01/2012; 4:85-91.
Article: Robotics as a new surgical minimally invasive approach to treatment of endometriosis: a systematic review.[show abstract] [hide abstract]
ABSTRACT: This systematic review evaluates the role of robotics in the surgical treatment of endometriosis. Electronic database searches were conducted in MEDLINE, Scopus, and ISI Web of Knowledge for relevant studies over the past 10 years. Four published articles were found that used robotic assisted laparoscopy to perform endometriosis surgery. All four studies used the da Vinci Surgical System (Intuitive Surgical Inc., Sunnyvale, CA, USA). Three studies were case reports, and one was a cohort study. Robotics appears to be as effective as conventional laparoscopy in the management of endometriosis. There were no reports of any major complications. Few studies have been published and show us that robotic endometriosis surgery is feasible even in severe endometriosis cases without conversion. There is a lack of long-term outcome papers in the literature. Randomized controlled trials are necessary.International Journal of Medical Robotics and Computer Assisted Surgery 12/2011; 8(2):160-5. · 1.59 Impact Factor
Article: Is Single-Port Access Laparoscopy Less Painful Than Conventional Laparoscopy for Adnexal Surgery? A Comparison of Postoperative Pain and Surgical Outcomes.[show abstract] [hide abstract]
ABSTRACT: Objective. This study aimed to compare postoperative pain and surgical outcomes after transumbilical single-port access (SPA) and conventional multiport laparoscopic surgery for adnexal lesions. Methods. A retrospective case-control study was conducted matched by age, body mass index, and frequency of previous abdominal surgery. A total of 110 SPA laparoscopy patients (cases) were matched with a cohort of 107 patients who underwent conventional laparoscopy (controls) for benign adnexal lesions. SPA system consisted of a wound retractor, surgical glove, two 5-mm trocars, and one 11-mm trocar. Postoperative pain scores were measured immediately after surgery and at 6, 24, and 48 hours postsurgery using the numerical rating scale. Results. Postoperative pain scores did not differ between the 2 groups (P = .552). However, higher number of painkiller administrations was observed in the SPA laparoscopy group (median 3 vs 1, P < .001). The type of surgery and intraoperative blood loss were the significant factors influencing the number of painkiller administrations after controlling for other parameters by linear regression (P < .0001). The SPA laparoscopy group had less intraoperative blood loss (45.3 vs 87.5 mL, P < .001) and shorter hospital stay (2.1 ± 0.8 vs 2.7 ± 1.0 days, P < .001) compared with the conventional laparoscopy group. Operative time and perioperative complications did not differ between groups. Conclusions. There was no difference in pain intensity between the SPA and conventional laparoscopic group in this study. Future trials are warranted to better define the benefits of SPA surgery in terms of postoperative pain.Surgical Innovation 03/2012; · 2.13 Impact Factor
