Feasibility and Safety of Laparoscopic-Assisted Bowel Segmental Resection for Deep Infiltrating Endometriosis: A Retrospective Cohort Study With Description of Technique.

STUDY OBJECTIVE: To evaluate the feasibility and safety of laparoscopic segmental bowel resection for deep infiltrating endometriosis (DIE). DESIGN: Retrospective clinical study (Canadian Task Force classification II-3). SETTING: Endoscopica Malzoni-Center for Advanced Endoscopic Gynecological Surgery, Avellino, Italy. PATIENTS: A retrospective cohort of 248 patients who underwent laparoscopic segmental bowel resection between January 1, 2011, and December 31, 2014. INTERVENTION: Laparoscopic segmental bowel resection for DIE. MEASUREMENTS AND MAIN RESULTS: Bowel endometriosis was histologically confirmed in all 248 of the 248 patients (100%). The mean length of the resected specimens was 11.83 ± 4.56 cm. In all cases, margins were free of disease. The muscular layer was infiltrated up to the submucosal layer in all 248 patients (100%), whereas the mucosal layer showed signs of infiltration in only 4 patients (1.6%). Two nodules were found in 36 patients (14.5%), and 3 nodules were found in only 8 patients (3.2%). None of the resected bowel segments had nodules shorter than 3 cm, and the majority of lesions had a longitudinal diameter of 3 to 7 cm. In the majority of cases, resected segments involved the mid to low rectum (distance from the lower margin of resected segment from the anal verge of 4 to 12 cm), whereas in 6% of cases, ultra-low resections (≤4 cm) were performed. No intraoperative complications occurred, and conversion to laparotomy was not required for any patient. Major perioperative and early and late postoperative complications occurred in 20 patients (8.06%). Significantly reduced pain associated with disease was observed up to the 1-year follow-up irrespective of postoperative hormonal treatment. Pelvic relapse was found in up to 50% of patients, especially in patients without hormonal suppression, but only in the form of endometriomas or adherences, with no recurrent deep lesions observed. CONCLUSION: This large single-center series demonstrates that laparoscopic bowel resection for DIE is a feasible technique, with low complication rates. In symptomatic patients, treating deep fibrotic endometriosis nodules by laparoscopic segmental resection is very effective in reducing pain and restoring bowel function. This surgical approach is safe but complex, requiring specific skills in laparoscopic urologic and colorectal procedures, and should be performed only in specialized high-volume centers by high-volume surgeons.

Laparoscopic staging of early ovarian cancer: results of a multi-institutional cohort study.

BACKGROUND: Minimal access surgery to stage early ovarian cancer (EOC) is still regarded as investigational among many gynecologic oncologists. Reporting outcome data from large cohorts is currently the only practical way to further define the appropriateness of minimally invasive surgery for EOC patients. We sought to investigate the safety, adequacy, and outcome of laparoscopic staging of EOC by using a multi-institutional sample. METHODS: Prospectively collected data in three gynecologic oncology service databases were searched for EOC patients undergoing laparoscopic staging. Surgical, pathologic, and oncologic outcome data were analyzed. RESULTS: The study cohort consisted of 82 women. The mean operative time was 263 ± 81 minutes. The median estimated blood loss was 100 (range 20-3000) ml. The median number of pelvic and para-aortic lymph nodes collected was 23 (3-39) and 13 (3-43), respectively. The disease was reclassified to a higher stage in 21 women (25.6%). No conversion to laparotomy occurred, and one patient had intraoperative hemorrhage requiring blood transfusion. Thirteen patients (15.8%) experienced postoperative complications. The median follow-up period was 28.5 (range 3-86) months. Overall survival and disease-free survival for the entire cohort were 98.8% and 95.1%, respectively. In the subgroup of patients who had reached or exceeded 3 years' follow-up (n = 34), 3-year overall survival and 3-year disease-free survival were 97% and 91.2%, respectively. CONCLUSIONS: When performed by appropriately skilled surgeons, laparoscopic comprehensive staging of EOC seems feasible and adequate, with surgicopathologic results that are reproducible in different practice settings.

Robotics versus laparoscopic radical hysterectomy with lymphadenectomy in patients with early cervical cancer: a multicenter study.

BACKGROUND: The aim of this study was to retrospectively compare the safety, morbidity, and recurrence rate of total laparoscopic radical hysterectomy (TLRH) with lymphadenectomy and total robotic radical hysterectomy (RRH) with lymphadenectomy for early cervical carcinoma in a series of 99 consecutive women. MATERIALS AND METHODS: We studied 99 consecutive patients with FIGO stage Ia1 (LVSI), Ia2, Ib1, Ib2, and IIa cervical cancer, 76 of whom underwent TLRH and 23 underwent RRH with pelvic lymph node dissection. Para-aortic lymphadenectomy, with the superior border of the dissection being the inferior mesenteric artery, was performed in all cases with positive pelvic lymph nodes discovered at frozen section evaluation. RESULTS: The mean blood loss was 157 ml in the RRH group (95% confidence interval [95% CI] 50-400) and 95 ml in the TLRH group (95% CI 30-500) (not significant [NS]). The median length of hospital stay was 3 days in the RRH group (95% CI 2-7) and 4 days in the TLRH group (95% CI 3-7) (NS). The mean operating time was 255 min for the TLRH group (95% CI 182-415) compared with 323 min in the RRH group (95% CI 161-433) (P < 0.05). No significant difference was found between the 2 groups when comparing the recurrence rate. CONCLUSIONS: Robotic radical hysterectomy can be considered a safe and effective therapeutic procedure for managing early-stage cervical cancer without significant differences, if compared with laparoscopic radical hysterectomy, in terms of the recurrence rate and intraoperative and postoperative complications, although multicenter randomized clinical trials with longer follow-up are necessary to evaluate the overall oncologic outcomes of this procedure.

Total laparoscopic hysterectomy versus abdominal hysterectomy with lymphadenectomy for early-stage endometrial cancer: a prospective randomized study.

OBJECTIVE: The aim of this study was to compare, in a series of 159 women the feasibility, safety and morbidity of total laparoscopic hysterectomy (LPS) and abdominal hysterectomy with lymphadenectomy (LPT) for early-stage endometrial cancer and to assess disease-free survival and recurrence rate. METHODS: 159 patients with clinical stage I endometrial cancer were enrolled in a prospective randomized trial and treated with LPS or LPT approach. The para-aortic lymphadenectomy was performed in all cases with positive pelvic lymph nodes discovered at frozen section evaluation, in patients with poorly differentiated tumors with myometrial invasion greater than 50% (ICG3), and non-endometrioid carcinomas. RESULTS: The mean operative time was 136 min+/-31 (95% CI 118-181) in the LPS group and 123 min+/-29 (95% CI 111-198) in the LPT group (P<0.01). The mean blood loss was 50 ml+/-12 in the LPS group (95% CI 20-90) and 145 ml+/-35 in the LPT group (95% CI 60-255) (P<0.01). The mean length of hospital stay was 5.1+/-1.2 in the LPT group (95% CI 1-7) and 2.1+/-0.5 in the LPS group (95% CI 1-5) (P<0.01). CONCLUSIONS: Laparoscopy is a suitable procedure for the treatment of patients with early endometrial cancer and may offer the potential benefits of decreased discomfort with decreased convalescence time without compromising the degree of oncological radicality required; however, it does not seem to modify the disease-free survival and the overall survival, although multicenter randomized trials and long-term follow-up are required to evaluate the overall oncologic outcomes of this procedure.

Is early stage endometrial cancer safely treated by laparoscopy? Complications of a multicenter study and review of recent literature.

BACKGROUND: To compare the complications after total laparoscopic hysterectomy (LPS) and abdominal hysterectomy with lymphadenectomy (LPT) for early stage endometrial cancer in a series of 226 women and to assess the disease-free survival and the recurrence rate. PATIENTS AND METHODS: Two hundred and twenty six patients with clinical stage I endometrial cancer were enrolled in a multicenter study and underwent surgical staging consisting of inspecting the intraperitoneal cavity, peritoneal washing, total hysterectomy, bilateral salpingo-oophorectomy, and in all cases we performed systematic bilateral pelvic lymphadenectomy by LPS or LPT approach. RESULTS: One patient of the LPS group had an uretero-vaginal fistula and another patient had an ureteral stricture temporarily treated with a stent. One patient of the LPS group had a bowel perforation due to dense adhesions with the peritoneum under the umbilicus, resolved with a bowel resection and an end-to-end anastomosis. In three patients of the LPS group we observed a vaginal cuff dehiscence and in one case a pelvic lymphocyst was reported. CONCLUSIONS: The low intraoperative and postoperative complications rate, observed in the LPS group, highlights the feasibility, safety and efficacy of this surgical approach. The operating time was longer in the LPS group but the recurrence rate and the complication rate appear similar and not more than what is traditionally expected with the LPT approach, although further studies and cost-benefit analyses are required to determine whether the use of LPS improves the outcome over standard LPT and whether the advantages of this technique could be extended to a larger proportion of patients.

Laparoscopic radical hysterectomy with lymphadenectomy in patients with early cervical cancer: our instruments and technique.

The purpose of this study is to describe the technique of total laparoscopic radical hysterectomy (type III procedure) with lymphadenectomy as performed at the Advanced Gynecological Endoscopy Center of the Malzoni Medical Center, Avellino, Italy. Seventy-seven patients underwent total laparoscopic radical hysterectomy (type II, III) with lymphadenectomy between January 2000 and March 2008. FIGO stage included five patients Ia1 with LVSI (lymph-vascular involvement), 24 patients Ia2, and 48 patients Ib1. 60 patients underwent a class III procedure and 17 patients a class II procedure according to the Piver classification. Histological types included squamous cell carcinoma in 65 patients, adenocarcinomas in 10 patients, and adenosquamous carcinoma in two. Para-aortic lymphadenectomy was performed up to the level of the inferior mesenteric artery in eight cases with positive pelvic lymph nodes at frozen section evaluation. Total laparoscopic radical hysterectomy can be considered a safe and effective therapeutic procedure for the management of early stage cervical cancer with a low morbidity; moreover, the laparoscopic route may offer an alternative option for patients undergoing radical hysterectomy, although multicenter studies and long-term follow-up are required to evaluate the oncologic outcomes of this procedure.

Feasibility, safety, and efficacy of conservative laparoscopic treatment of borderline ovarian tumors.

OBJECTIVE: To outline the most recent information regarding conservative laparoscopic surgery for young women with borderline ovarian tumors. DESIGN: Review article. SETTING: Advanced Gynecological Endoscopy Center, Malzoni Medical Center, Avellino, Italy. PATIENT(S): Young women with low-stage borderline ovarian tumors who wish to preserve their fertility. INTERVENTION(S): Conservative laparoscopic surgery with unilateral salpingo-oophorectomy or cystectomy. MAIN OUTCOME MEASURE(S): Recurrence rate and outcomes. RESULT(S): Laparoscopic cystectomy may have more chance of preserving a woman's fertility compared with adnexectomy because of the removal of less ovarian tissue. Its greatest danger is the risk of inadvertently leaving behind some malignant cells. Therefore, this procedure should be reserved for patients with previous unilateral salpingo-oophorectomy or when bilateral lesions are present to preserve at least some ovarian tissue. CONCLUSION(S): When borderline ovarian tumors are identified at surgery by intraoperative histology, the recommended conservative treatment should be laparoscopic salpingo-oophorectomy. Recurrence can be noted after this type of treatment, but the cases of recurrent disease can be detected with close follow-up and treated accordingly. For these reasons, careful selection of candidates for this kind of treatment is, of course, necessary and close follow-up is required. If these restrictions are rigorously applied, then fertility-sparing surgery may be considered a safe option for this pathology, but all laparoscopic procedures should be reserved for oncologic surgeons trained in extensive laparoscopic procedures.

Feasibility, morbidity, and safety of total laparoscopic radical hysterectomy with lymphadenectomy: our experience.

STUDY OBJECTIVE: The purpose of this study was to retrospectively evaluate, in a series of 65 patients, the feasibility, morbidity, and safety of total laparoscopic radical hysterectomy with lymphadenectomy for early cervical carcinoma. DESIGN: Retrospective, nonrandomized study (Canadian Task Force classification II-2). SETTING: Advanced Gynecological Endoscopy Center, Malzoni Medical Center, Avellino, Italy. PATIENTS: Sixty-five nonconsecutive patients with International Federation of Gynecology and Obstetrics (FIGO) stage Ia1 with lymphvascular space involvement, Ia2, and Ib1 early cervical cancer. INTERVENTION: Fourteen patients underwent a laparoscopic class II procedure, and 51 patients underwent a class III procedure according to the Piver classification. All the patients underwent total laparoscopic radical hysterectomy with pelvic lymphadenectomy during the study period, and none of the surgeries required conversion to laparotomy. Paraaortic lymphadenectomy is not routinely performed unless suspicious pelvic lymph nodes are confirmed to have metastatic disease on frozen section evaluation. MEASUREMENTS AND MAIN RESULTS: Fifty-six patients had squamous cell carcinoma; 7 patients had adenocarcinomas, and 2 had adenosquamous carcinoma. The mean age was 40.5 years (95% CI 27.7-69.1) and the SD was +/- 7.5. The median weight was 56.2 kg (range 44-75 kg). The median operative time was 196 minutes (range 182-240 minutes), and the surgical margins were free of disease in all cases. The median blood loss was 55 mL (range 30-80 mL). No patient required an intraoperative blood transfusion. The median length of hospital stay was 4 days (range 3-7 days). CONCLUSION: Laparoscopic treatment of cervical cancer offers patients the potential benefits of decreased discomfort with decreased convalescence time, but it should be reserved for oncologic surgeons trained in extensive laparoscopic procedures.
