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.

Laparoscopy versus minilaparotomy in women with symptomatic uterine myomas: short-term and fertility results

OBJECTIVE To retrospectively compare the feasibility, safety, morbidity, and pregnancy outcome of laparoscopy (LPS) and minilaparotomy (LPT) in the treatment of symptomatic uterine myomas. DESIGN Retrospective, nonrandomized study. SETTING Advanced Gynecological Endoscopy Center, Malzoni Medical Center, Avellino, Italy. PATIENT(S) 680 nonconsecutive patients with symptomatic uterine myomas. INTERVENTION(S) 350 women underwent LPS, and 330 underwent LPT myomectomy. MAIN OUTCOME MEASURE(S) Operative time, blood loss, hospital stay, pregnancy rate, and spontaneous abortion rate. RESULT(S) The mean operative time was 63 +/- 21 minutes (95% CI, 48-143) in the LPS group and 57 +/- 23 minutes (95% CI, 38-121) in the LPT group. The mean length of hospital stay was statistically significantly greater in the LPT group (3.1 +/- 0.5; 95% CI, 1-5) than the LPS group (2.1 +/- 0.8; 95% CI, 1-4). The overall spontaneous pregnancy rate after myomectomy was 53%; the pregnancy rate after LPS myomectomy (56%) was not statistically significantly higher than the rate for LPT (50%). CONCLUSION(S) Laparoscopy showed a lower morbidity than reported for the open approach and was characterized by less blood loss and a shorter postoperative hospitalization with an higher pregnancy rate. The operating time was not much longer in the laparoscopic group, and the intraoperative and postoperative complications appeared acceptable and not more than what is traditionally expected with the open approach.

Definition of a dynamic laparoscopic model for the prediction of incomplete cytoreduction in advanced epithelial ovarian cancer: Proof of a concept

OBJECTIVE To develop an updated laparoscopy-based model to predict incomplete cytoreduction (RT>0) in advanced epithelial ovarian cancer (AEOC), after the introduction of upper abdominal surgery (UAS). PATIENTS AND METHODS The presence of omental cake, peritoneal extensive carcinomatosis, diaphragmatic confluent carcinomatosis, bowel infiltration, stomach and/or spleen and/or lesser omentum infiltration, and superficial liver metastases was evaluated by staging laparoscopy (S-LPS) in a consecutive series of 234 women with newly diagnosed AEOC, receiving laparotomic PDS after S-LPS. Parameters showing a specificity≥75%, PPV≥50%, and NPV≥50% received 1 point score, with an additional one point in the presence of an accuracy of ≥60% in predicting incomplete cytoreduction. The overall discriminating performance of the LPS-PI was finally estimated by ROC curve analysis. RESULTS No-gross residual disease at PDS was achieved in 135 cases (57.5%). Among them, UAS was required in 72 cases (53.3%) for a total of 112 procedures, and around 25% of these patients received bowel resection, excluding recto-sigmoid resection. We observed a very high overall agreement between S-LPS and laparotomic findings, which ranged from 74.7% for omental cake to 94.8% for stomach infiltration. At a LPS-PIV≥10 the chance of achieving complete PDS was 0, and the risk of unnecessary laparotomy was 33.2%. Discriminating performance of LPS-PI was very high (AUC=0.885). CONCLUSIONS S-LPS is confirmed as an accurate tool in the prediction of complete PDS in women with AEOC. The updated LPS-PI showed improved discriminating performance, with a lower rate of inappropriate laparotomic explorations at the established cut-off value of 10.

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 womans 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.

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.

Telelap ALF-X vs Standard Laparoscopy for the Treatment of Early-Stage Endometrial Cancer: A Single-Institution Retrospective Cohort Study

STUDY OBJECTIVE To compare the surgical and clinical outcomes of patients affected by early-stage endometrial cancer treated using the Telelap ALF-X platform versus conventional laparoscopic surgery. DESIGN Single institution retrospective cohort study (Canadian Task Force classification II-2). SETTING Department of Obstetrics and Gynecology, Division of Gynecologic Oncology, Catholic University of the Sacred Heart, Rome, Italy. PATIENTS The study involved 89 patients affected by early-stage endometrial cancer who underwent elective surgical staging between October 2013 and September 2014. Among them, 43 (48.3%) underwent Telelap ALF-X staging (ALF-X group), and 46 (51.7%) underwent conventional laparoscopic staging (laparoscopic group). INTERVENTIONS All selected patients underwent laparoscopic staging with radical hysterectomy (class A sec Querleu-Morrow), bilateral salpingo-oophorectomy, and pelvic lymphadenectomy if required. The 2 surgical groups were further divided into patients who did not require pelvic lymphadenectomy (subgroup 1) and those who underwent pelvic lymphadenectomy (subgroup 2). MEASUREMENTS AND MAIN RESULTS In the ALF-X group, the median operative time was 128 minutes (range, 69-260 minutes) for subgroup 1 and 193 minutes (range, 129-290 minutes) for subgroup 2. In the laparoscopic group, the median operative time was 82 minutes (range, 25-180 minutes) in subgroup 1 and 104 minutes (range, 36-160 minutes) in subgroup 2. The difference in operative time between subgroups was statistically significant in both the ALF-X and laparoscopic groups (p = .000). In subgroup 1 of the ALF-X group, there was 1 conversion to standard laparoscopy (2.3%) and 2 conversions to laparotomy (4.7%) (p = .234). No conversions to laparotomy occurred in the laparoscopic group. Postoperative complications included 1 case of pelvic hematoma (2.3%) in subgroup 1 of the ALF-X group and 1 case of subocclusion and 1 case of pulmonary edema (4.3%) in subgroup 1 of the laparoscopic group. CONCLUSION Based on operative outcomes and complication rates, our results suggest that the Telelap ALF-X approach is feasible and safe for endometrial cancer staging; however, further studies are needed to definitively assess the role of Telelap ALF-X early-stage endometrial cancer staging.

Minilaparoscopic radical hysterectomy for cervical cancer: Multi-institutional experience in comparison with conventional laparoscopy

OBJECTIVE To analyze the preliminary experience of three gynecologic oncology services with minilaparoscopic radical hysterectomy (mLRH) for the treatment of cervical cancer and to compare perioperative outcomes with those of conventional laparoscopic surgery (LRH). METHODS Prospectively collected data on consecutive cervical cancer patients undergoing radical hysterectomy with a laparoscopic approach were analyzed retrospectively. Perioperative outcomes of women undergoing mLRH were compared to data from control patients who had undergone LRH with 5-mm instruments. Adjustment for potential selection bias in surgical approach was made with propensity score (PS) matching. RESULTS The study cohort consisted of 257 patients, 35 undergoing mLRH and 222 undergoing LRH. The two groups were comparable in terms of demographic and tumor characteristics. No significant differences were observed between groups in terms of operative time, blood loss, lymph node yield, amount of parametrial or vaginal cuff tissue removed, and percentage of intra- or postoperative complications, both in the entire cohort and in the PS matched group. No conversions were needed from mLRH to standard laparoscopy or from minilaparoscopy to open surgery. Conversion from standard laparoscopy to open surgery was necessary in 2 patients. A shorter hospital stay was observed among women who had mLRH than in those undergoing LRH [2 (1-10) vs 4 (1-14) days, p = 0.005]. This difference remained significant after PS matching. CONCLUSION Our preliminary study suggests that in experienced hands minilaparoscopy is a feasible and safe technique for radical hysterectomy and yields results that are equivalent to those of LRH.

A laparoscopic risk-adjusted model to predict major complications after primary debulking surgery in ovarian cancer: A single-institution assessment

OBJECTIVE To develop and validate a simple adjusted laparoscopic score to predict major postoperative complications after primary debulking surgery (PDS) in advanced epithelial ovarian cancer (AEOC). METHODS From January 2006 to June 2015, preoperative, intraoperative, and post-operative outcome data from patients undergoing staging laparoscopy (S-LPS) before receiving PDS (n=555) were prospectively collected in an electronic database and retrospectively analyzed. Major complications were defined as levels 3 to 5 of MSKCC classification. On the basis of a multivariate regression model, the score was developed using a random two-thirds of the population (n=370) and was validated on the remaining one-third patients (n=185). RESULTS Major complication rate was 18.3% (102/555). Significant predictors included in the scoring system were: poor performance status, presence of ascites (>500cm(3)), CA125 serum level (>1000U/ml), and high laparoscopic tumor load (predictive index value, PIV ≥8). The mean risk of developing major postoperative complications was 3.7% in patients with score 0 to 2, 13.2% in patients with score 3 to 5, 37.1% in patients with score 6 to 8. In the validation population, the predicted risk of major complications was 17.8% (33/185) versus a 16.7% (31/185) observed risk (C-statistic index=0.790). CONCLUSION This new score may accurately predict a patients postoperative outcome. Early identification of high-risk patients could help the surgeon to adopt tailored strategies on individual basis.

Near-Infrared Imaging with Indocyanine Green for Detection of Endometriosis Lesions (Gre-Endo Trial): A Pilot Study

STUDY OBJECTIVE To evaluate near-infrared radiation imaging with intravenous indocyanine green (NIR-ICG) during laparoscopic intervention to identify endometriosis lesions. DESIGN A single-center, prospective, single-arm pilot study (Canadian Task Force classification II-2). SETTING An academic tertiary care and research center. PATIENTS Twenty-seven patients with symptomatic endometriosis were enrolled. INTERVENTIONS Patients underwent laparoscopic surgery using a laparoscopic system prototype with NIR-ICG. MEASUREMENTS AND MAIN RESULTS A total of 116 suspected endometriosis lesions were removed from 27 patients. One hundred lesions had already been visualized in white light imaging by an expert surgeon; the remaining 16 were detected and removed using NIR-ICG. A total of 111 specimens were positive for endometriosis pathology. Positive predictive value of 95% and 97.8% and negative predictive value of 86.2% and 82.3% were found by white light imaging and NIR-ICG, respectively, with sensitivity of 85.6% and 82% and specificity of 95.2% and 97.9%, respectively. CONCLUSION NIR-ICG may be a tool for intraoperative diagnosis, confirmation of visible endometriosis lesions, and a marker for identifying occult endometriosis. Further prospective studies with a larger population sample are warranted to validate these encouraging preliminary results.
