Comparison of robotic-assisted and conventional laparoscopy in the management of adnexal masses.

STUDY OBJECTIVE: To compare the outcome of robotic-assisted laparoscopy vs conventional laparoscopy in the management of ovarian masses. DESIGN: Retrospective cohort (Canadian Task Force classification II-3). SETTING: Academic medical centre in the northeast United States. PATIENTS: Retrospective medical record review of 71 consecutive patients with presumed benign ovarian masses. INTERVENTION: Robotic-assisted laparoscopy in 30 patients with presumed benign ovarian masses was compared with conventional laparoscopy in 41 patients. MEASUREMENTS AND MAIN RESULTS: Operative outcomes including operative time, estimated blood loss, length of hospital stay, and complications were recorded. Standard statistical analysis was used to compare the outcomes in the 2 groups. Mean (SD) operative time in the robotic group was 1.95 (0.63) hours, which was significantly longer than in the conventional laparoscopic group, 1.28 (0.83) hours (p = .04). Estimated blood loss in the robotic group was 74.52 (56.23) mL, which was not significantly different from that in the conventional laparoscopic group, 55.97 (49.18) mL. There were no significant differences in length of hospital stay between the robotic and conventional laparoscopic groups: 1.20 (0.78) days and 1.48 (0.63). Conversion to laparotomy was not necessary in either group of patients. Intraoperative and postoperative complications were similar between the 2 groups. CONCLUSION: Robotic-assisted laparoscopy is a safe and efficient technique for management of various types of ovarian masses. However, conventional laparoscopy is preferred for management of ovarian masses because of shorter operative time. Prospective studies are needed to evaluate the outcomes of robotic-assisted laparoscopic management of benign and malignant ovarian neoplasms.

A case-controlled study of total laparoscopic radical hysterectomy with pelvic lymphadenectomy versus radical abdominal hysterectomy in a fellowship training program.

To determine whether total laparoscopic radical hysterectomy (TLRH) is a feasible alternative to an abdominal radical hysterectomy (ARH) in a gynecologic oncology fellowship training program. We prospectively collected cases of all of the patients with cervical cancer treated with TLRH and pelvic lymphadenectomy by our division from 2000 to 2006. All of the patients from the TLRH group were matched 1:1 with the patients who had ARH during the same period based on stage, age, histological subtype, and nodal status. Thirty patients were treated with TLRH with a mean age of 48.3 years (range, 29-78 years). The mean pelvic lymph node count was 31 (range, 10-61) in the TLRH group versus 21.8 (range, 8-42) (P < 0.01) in the ARH group. Mean estimated blood loss was 200 cc (range, 100-600 cc) in the TLRH with no transfusions compared to 520 cc in the ARH group (P < 0.01), in which five patients required transfusions. Mean operating time was 318.5 min (range, 200-464 min) compared to 242.5 min in the ARH group (P < 0.01), and mean hospital stay was 3.8 days (range, 2-11 days) compared to 5.6 days in the ARH group (P < 0.01). All TLRH cases were completed laparoscopically. All patients in the TLRH group are disease free at the time of this report. In conclusion, it is feasible to incorporate TLRH training into the surgical curriculum of gynecologic oncology fellows without increasing perioperative morbidity. Standardization of TLRH technique and consistent guidance by experienced faculty is imperative.

Ovarian remnant syndrome after laparoscopic oophorectomy.

OBJECTIVE: To report the surgical history, clinical characteristics, and operative technique used in patients with ovarian remnant syndrome after laparoscopic oophorectomy. DESIGN: Observational study. SETTING: Teaching hospital and private practice office. PATIENT(S): Nineteen patients with documented history of unilateral or bilateral laparoscopic oophorectomies with histologic confirmation of ovarian remnants. INTERVENTION(S): Operative laparoscopy for resection of ovarian remnants. MAIN OUTCOME MEASURE(S): Risk factors and surgical technique contributing to ovarian remnant syndrome. RESULT(S): The patients underwent a mean of 4.7 previous surgical procedures (range, two to nine): 12 had bilateral oophorectomy, and seven had unilateral oophorectomy. The infundibulopelvic ligament had been secured with bipolar desiccation in 11 patients, pretied surgical loops in six, and a linear stapler in two. Cystic ovarian remnants were identified by pelvic sonography in 12 women and by computed tomography (CT) scan in one. Six women underwent reoperation, two for ovarian remnants in different sites. CONCLUSION(S): With laparoscopic oophorectomy there is risk of ovarian remnant due to improper tissue extraction or misapplication or improper use of pretied surgical loops, linear stapler, or bipolar electrodesiccation on the infundibulopelvic ligament, especially in women with a history of multiple pelvic surgeries, adhesions, or endometriosis.

Laparoscopic adhesiolysis and relief of chronic pelvic pain.

OBJECTIVE: To evaluate the short- and long-term results of laparoscopic enterolysis in patients with chronic pelvic pain following hysterectomy. METHODS: Forty-eight patients were evaluated at time intervals from 2 weeks to 5 years after laparoscopic enterolysis. Patients were asked to rate postoperative relief of their pelvic pain as complete/near complete relief (80-100% pain relief), significant relief (50-80% pain relief), or less than 50% or no pain relief. RESULTS: We found that after 2 to 8 weeks, 39% of patients reported complete/near complete pain relief, 33% reported significant pain relief, and 28% reported less than 50% or no pain relief. Six months to one year postlaparoscopy, 49% of patients reported complete/near complete pain relief, 15% reported significant pain relief, and 36% reported less than 50% or no pain relief. Two to five years after laparoscopic enterolysis, 37% of patients reported complete/near complete pain relief, 30% reported significant pain relief, and 33% reported less than 50% or no pain relief. Some patients required between 1 and 3 subsequent laparoscopic adhesiolysis. A total of 3 enterotomies and 2 cystotomies occurred, all of which were repaired laparoscopically. CONCLUSION: We conclude that laparoscopic enterolysis may offer significant long-term relief of chronic pelvic pain in some patients.

Laparoscopic vesicopsoas hitch for infiltrative ureteral endometriosis.

OBJECTIVE: To report the technique and outcome of a laparoscopic vesicopsoas hitch used for the treatment of infiltrative ureteral endometriosis. DESIGN: Case report. SETTING: A tertiary care center. PATIENT(S): A 36-year-old woman with infiltrative endometriosis of the ureter. INTERVENTION(S): A laparoscopic vesicopsoas hitch. MAIN OUTCOME MEASURE(S): The return of normal ureteral function as measured by IV pyelography and ultrasonography. RESULT(S): After partial ureteral resection, it was noted that a tension-free anastomosis to the bladder was not possible. Thus, a laparoscopic vesicopsoas hitch was performed. CONCLUSION(S): A vesicopsoas hitch can be performed successfully by laparoscopy.

Recurrence rate after laparoscopic myomectomy.

STUDY OBJECTIVE: To determine the recurrence rate of myomas after laparoscopic myomectomy. DESIGN: Retrospective review (Canadian Task Force classification II-2). SETTING: Tertiary referral center. PATIENTS: One hundred fourteen women (age 25-51 yrs, median 38 yrs) who were followed for an average of 37 months (range 6-120 mo). INTERVENTION: Laparoscopic myomectomy. MEASUREMENTS AND MAIN RESULTS: Follow-up data were obtained by chart review and from returned questionnaires. Variables were date of surgery, first diagnosis of recurrence, and last follow-up visit. There were 38 (33.3%) recurrences after an average interval of 27 months. Twenty-four of these women did not require treatment. Eight underwent a second laparoscopic myomectomy, and one had a third. One patient had myomectomy and then hysterectomy, and six patients chose hysterectomy to treat the first recurrence. Cumulative risk of recurrence (Kaplan-Meier curve) was 10.6% after 1 year, 31.7% after 3 years, and 51.4% after 5 years. CONCLUSION: Although laparoscopic myomectomy is associated with less morbidity than removal by laparotomy, our results suggest that recurrence of myomas may be higher with the laparoscopic approach. Of 38 women with recurrent myoma, however, only 14 (36.8%) required additional surgery.

Laparoscopic treatment of type IV rectovaginal fistula.

Fistulas between the anorectum and vagina may arise from several causes. Treatment depends on their etiology and location, as well as the surgeon's experience. Operative laparoscopy was successful in two women with type IV (mid)rectovaginal fistula in whom previous surgical attempts failed. Our experience suggests that mid and high rectovaginal fistulas can be effectively treated by laparoscopy in the hands of experienced endoscopic surgeons.

Long-term outcome of laparoscopic presacral neurectomy for the treatment of central pelvic pain attributed to endometriosis.

OBJECTIVE: To evaluate the long-term pain reduction achieved by laparoscopic presacral neurectomy. METHODS: One hundred seventy-six women with median (range) age 30 (18-45) years underwent presacral neurectomy combined with excision and vaporization of endometriotic lesions and were observed, using structured questionnaires, for up to 72 months postoperatively. The study included a convenience sample of the first 100 questionnaires returned. Forty of the women were studied for 12-23 months, and 60 for 24-72 months. The main outcome measures were reduction of pelvic pain, dysmenorrhea, and dyspareunia after surgery. RESULTS: Pelvic pain, dysmenorrhea, and dyspareunia were reportedly reduced by more than 50% in 74, 61, and 55 patients, respectively, more than 12 months after laparoscopic presacral neurectomy. More than 50% reduction in pelvic pain was reported by 69.8%, 77.3%, 71.4%, and 84.6% of the patients, respectively, with endometriosis stages I-IV, using the revised classification of the American Fertility Society. Comparatively, more than 50% reduction in dysmenorrhea was reported by 52.8% of the patients with stage I endometriosis, 68.2% with stage II, 71.4% with stage III, and 69.2% with stage IV. Reduction of dyspareunia by more than 50% was reported by 54.7% of the patients with stage I endometriosis, 50.0% with stage II, 28.6% with stage III, and 61.5% with stage IV. CONCLUSION: Long-term outcome of laparoscopic presacral neurectomy is satisfactory in the majority of patients. The stage of endometriosis is not related directly to the degree of pain improvement achieved.

Laparoscopic management of pelvic pathology during pregnancy.

Advanced operative laparoscopy is being performed increasingly for various indications and in diverse patient populations, including gravid women. In the United States approximately 1.6% to 2.2% of pregnant women require nonobstetric surgery for abdominal and pelvic pathology. Increasing numbers of case reports suggest the feasibility and safety of operative laparoscopy during pregnancy. We identified certain management issues specific to these procedures based on our experience with nine cases of operative laparoscopy in women with gestations up to 22 weeks.

Laparoscopy during pregnancy: a literature review.

OBJECTIVE: To review the literature regarding the role of laparoscopy during pregnancy, particularly adnexal mass and non-obstetric surgery, incorporating the results of a series of 9 cases of laparoscopy during pregnancy at our centers. MATERIALS AND METHODS: A Medline search was performed to review the literature, and the reference lists provided by those articles were further explored for citations regarding laparoscopic adnexal surgery, appendectomy, and cholecystectomy. Our series of 9 patients consisted of pregnant patients with adnexal mass or acute abdomen who would otherwise have undergone exploratory laparotomy. Follow-up data for these 9 cases were collected by office visits, inquiry to the primary referring physicians, and telephone calls to the patient. RESULTS: The literature search yielded 42 additional cases of operative pelvic laparoscopy and 51 cases of abdominal operative laparoscopy (cholecystectomy and appendectomy). The publications, particularly regarding cholecystectomy, were supportive of the laparoscopic approach during pregnancy. All of the patients in our series had favorable outcomes. CONCLUSIONS: Advanced operative laparoscopy has been successfully performed for certain indications during pregnancy.

Comparison of transvaginal sonography and bimanual pelvic examination in patients with laparoscopically confirmed endometriosis.

To determine the usefulness of noninvasive clinical tests to diagnose symptomatic endometriosis, we retrospectively reviewed the medical records of 91 patients with chronic pelvic pain and laparoscopically confirmed endometriosis. Thirty-seven women (41%) had pelvic peritoneal endometrial implants with adhesions; in 44 (48%) the ovaries were also affected, and in 10 (11%) the disease involved both the uterus and ovaries. Seventy-nine (87%) women had dysmenorrhea, dyspareunia, or both. Forty-three (47%) had a normal bimanual pelvic examination and 37 (41%) an unremarkable transvaginal sonographic evaluation (no significant difference). The women were divided into two groups: group 1, in whom the disease extended to the ovaries and uterus, and group 2, those in whom only peritoneal implants and adhesions were present. In group 1, 48 women (89%) had an abnormal ultrasonographic evaluation compared with only 4 (11%) in group 2 (p <0.001). Our findings indicate that bimanual pelvic examination and transvaginal sonography are equally accurate in detecting endometriosis; however, when the uterine surface and ovaries are involved, the latter is more informative. Therefore, patients with chronic pelvic pain, especially pain related to menstruation or coitus, should be evaluated laparoscopically to diagnose mild endometriosis adequately.

Laparoscopic segmental bladder resection for endometriosis: a report of two cases.

BACKGROUND: The proper treatment of bladder endometriosis is unknown. CASE: Two women with endometriosis involving the full thickness of the bladder wall experienced persistent hematuria during menstruation. They had not responded to previous conservative medical or surgical therapy, so we performed laparoscopic segmental resection, with satisfactory results. CONCLUSION: Hematuria during menstruation due to endometriosis of the bladder is uncommon. In the two cases presented, good results followed laparoscopic segmental resection.

Laparoscopic radical hysterectomy and laparoscopically assisted vaginal radical hysterectomy with pelvic and paraaortic node dissection.

Nineteen women underwent laparoscopic radical hysterectomy or laparoscopically assisted vaginal radical hysterectomy, with pelvic node dissection and paraaortic node dissection when indicated. One procedure was converted to laparotomy due to equipment failure (at The University of Puerto Rico). There were two minor postoperative complications. The first, febrile morbidity resulting from a urinary tract infection, responded to medical therapy. The second was incisional bleeding, which was controlled with sutures applied using a local anesthetic. No major postoperative complications were noted, there have been no incidents of recurrence, and the follow-up results are encouraging.

Laparoscopic radical hysterectomy with paraaortic and pelvic node dissection.

We report the first case of a laparoscopic radical hysterectomy and paraaortic and pelvic lymphadenectomy to treat a stage IA2 carcinoma of the cervix. To our knowledge, a laparoscopic radical hysterectomy with laparoscopic paraaortic lymphadenectomy has not been previously described.

Videolaseroscopy. The CO2 laser for advanced operative laparoscopy.

A specific technique of advanced operative laparoscopy, known as videolaseroscopy, using the CO2 laser and videomonitor, is described. Operating room setup, anesthesia considerations, and specific applications to pelvic disease are elaborated.

Comparison of direct insertion of disposable and standard reusable laparoscopic trocars and previous pneumoperitoneum with Veress needle.

A randomized prospective study was conducted to evaluate the ease of use and safety of direct insertion of laparoscopic trocars. Comparison of previous pneumoperitoneum by Veress needle insertion with direct insertion of the reusable conventional laparoscopic trocar and direct insertion of the disposable shielded trocar revealed minor complication rates of 22, 6 and 0%, respectively. No major complications occurred in this series of 200 patients.

Adhesion reformation after reproductive surgery by videolaseroscopy.

After initial videolaseroscopy for the treatment of endometriosis-associated infertility, 157 patients underwent a second-look laparoscopy to evaluate and treat recurrence of disease and/or adhesions. The patients were divided into two groups. Group 1 consisted of 135 patients who underwent second-look laparoscopy for persistent infertility and/or recurrence of pain. Group 2 consisted of 22 patients who achieved pregnancy after initial surgery and underwent second-look laparoscopy for evaluation of ectopic pregnancy or in association with uterine evacuation for first trimester spontaneous abortion. Both groups of patients demonstrated a significant reduction in adhesion scores involving the ovaries, tubes, posterior cul-de-sac, anterior cul-de-sac, and omentum/bowel. Although the initial mean adhesion scores were similar for both groups, at second-look laparoscopy the mean adhesion scores were significantly lower for group 2, particularly for ovarian and tubal adhesions. None of the patients formed de novo adhesions. From these results we may conclude that videolaseroscopy: (1) is effective in reducing peritoneal adhesions; (2) is associated with a low frequency of postoperative adhesion recurrence; and (3) appears to completely avoid de novo adhesion formation.

Safe laser endoscopic excision or vaporization of peritoneal endometriosis.

In using laser laparoscopy for the treatment of endometriosis, protecting patients from inadvertent injury to pelvic structures adjacent to diseased tissue has been a major concern. In many cases, because of this risk, surgeons have stopped short of effecting thorough treatment of endometrial implants on the bowel, bladder, ureters, or great vessels. In a large series of patients, we have used hydrodissection successfully with few complications. We believe that the technique of hydrodissection is a safe and efficient method, permitting more thorough treatment of endometriosis that otherwise might be deemed untreatable by laser laparoscopy.
