Analysis of para-aortic lymphadenectomy up to the level of the renal vessels in apparent early-stage ovarian cancer

Prognostic significance and risk factors for pelvic and para-aortic lymph node metastasis in type I and type II ovarian cancer: a large population-based database analysis

BACKGROUND

To compare the prognosis of lymphatic metastasis in type I and type II epithelial ovarian cancer (OC) and to identify the risk factors for pelvic lymph node metastases (PLNs) and para-aortic lymph node metastases (PALNs).

METHODS

Patients diagnosed with epithelial OC were collected from the Surveillance, Epidemiology, and End Results (SEER) database. Overall survival (OS) and cancer-specific survival (CSS) were estimated. The Cox proportional hazards regression model was used to identify independent predictors of survival.

RESULTS

A total of 11,275 patients with OC were enrolled, including 31.2% with type I and 68.8% with type II. Type II and high tumour stage were risk factors for lymph node involvement (p < 0.05). The overall rate of lymph node metastasis in type I was 11.8%, and that in type II was 36.7%. In the type I group, the lymph node metastasis rates in stages T1, T2, T3 and T_XM₁ were 3.2%, 14.5%, 40.4% and 50.0%, respectively. In the type II group, these rates were 6.4%, 20.4%, 54.1% and 61.1%, respectively. Age and tumour size had little effect on lymph node metastasis, and grade 3 was not always a risk factor. For the type I group, the 10-year CSS rates of LN(-), PLN( +), PALN( +), and PLN + PALN( +) were 80.6%, 46.6%, 36.3%, and 32.3%, respectively. The prognosis of PLN ( +) was better than that of PALN ( +) in the type I group (p > 0.05). For the type II group, the 10-year CSS rates of LN(-), PLN( +), PALN( +), and PLN + PALN( +) were 55.6%, 18.5%, 25.7%, and 18.2%, respectively. PALN ( +) had a significantly better prognosis than PLN ( +) in the type II group (p < 0.05).

CONCLUSIONS

The clinical characteristics and prognoses of patients with type I and type II OC differed greatly. Patients with type II and higher tumour stages had poorer prognoses. Type I with PALN metastasis and type II with PLN metastasis indicated a worse prognosis. Patients with stage TI did not require lymph node dissection, especially in the type I group.

LncRNA MAFG-AS1 promotes the malignant phenotype of ovarian cancer by upregulating NFKB1-dependent IGF1

Long non-coding RNAs (lncRNAs) were recently recognized to vitally function in a variety of cancer cellular events, including epithelial-mesenchymal transition (EMT), invasion, and migration, particularly in ovarian cancer (OC). Herein, we sought to investigate the potential role of MAFG-AS1 in the malignant behaviors of OC cells. The binding affinity between MAFG-AS1, miR-339-5p, NFKB1 or IGF1 was characterized so as to identify the underlying mechanism of corresponding their interactions. We conducted MAFG-AS1 overexpression or knockdown along with NFKB1 and IGF1 silencing to examine their effects on the EMT, migration, and invasion of OC cells. Tumors were xenografted in nude mice to validate the in vitro findings. Our data showed significantly high expression pattern of MAFG-AS1 in the OC tissues and cells. Further mechanistic investigations revealed that MAFG-AS1 upregulated the IGF1 expression pattern through recruitment of NFKB1, whereas MAFG-AS1 upregulated the NFKB1 expression pattern through binding to miR-339-5p. Thus, MAFG-AS1 overexpression accelerated the EMT, invasion, and migration of OC cells, which could be annulled by silencing of IGF1 or NFKB1. Besides, our in vitro findings were successfully recapitulated in the xenograft mice. These results determined that MAFG-AS1 stimulated the OC malignant progression by upregulating the NFKB1-mediated IGF1 via miR-339-5p, thus highlighting a novel potential therapeutic target against OC.

Circ_0067934 reduces JNK phosphorylation through a microRNA-545-3p/PPA1 axis to enhance tumorigenesis and cisplatin resistance in ovarian cancer

BACKGROUND

Circular RNA 0067934 (circ_0067934) has been revealed as a cancer driver in multiple human malignancies, whereas its action in the pathogenesis of ovarian cancer (OC) remains unclear. This study focuses on the function of circ_0067934 in tumorigenesis and cisplatin (DDP) resistance in OC and the molecular mechanism.

METHODS

Expression of circ_0067934 in OC tissues and cells was examined, and its correlation with the clinical characteristics of patients was analyzed. Candidate targets of circ_0067934 were predicted using bioinformatics systems. Binding relationships between circ_0067934 and microRNA (miR)-545-3p and between miR-545-3p and inorganic pyrophosphatase 1 (PPA1) were validated via luciferase assays. Gain- and loss-of functions of circ_0067934, miR-545-3p and PPA1 were performed to determine their functions in proliferation, invasion, apoptosis and DDP resistance of OC cells in vitro and in vivo.

RESULTS

Circ_0067934 was overexpressed in OC samples and associated with advanced tumor staging and lymph node metastasis. Downregulation of circ_0067934 reduced DDP resistance of the DDP-resistant A2780/DDP cell line and reduced cell proliferation and invasion, but the malignant behaviors of OC cells were restored after further miR-545-3p downregulation. Circ_0067934 served as a sponge for miR-545-3p and diminished its suppressive effect on PPA1 translation. Artificial upregulation of PPA1 enhanced proliferation, invasion and DDP resistance of A2780/DDP cells, and it reduced phosphorylation of the pro-apoptotic JNK signaling. Similar results were found in vivo.

CONCLUSION

This study suggests that circ_0067934 sequesters miR-545-3p and enhances PPA1 expression to promote tumorigenesis and DDP resistance in OC. This study may provide novel approaches in the management of OC.

Survival impact of number of removed para-aortic lymph nodes in stage I epithelial ovarian cancer

PURPOSE

The survival effect of presence or absence of lymphadenectomy in early-stage epithelial ovarian cancer (EOC) was priorly shown but the effect of number of removed lymph nodes kept in background. We aimed to evaluate the survival impact of number of removed lymph nodes and their localizations in stage I EOC.

METHODS

This study included 182 patients. The best cut-off levels for number of pelvic and para-aortic lymph nodes (PaLN) were 24 and 10, respectively. Univariate and multivariate survival analyses were performed for these cut-offs and other prognostic factors.

RESULTS

The median age of the patients was 49. The median number of removed pelvic and paraartic lymph nodes were 29 and 9, respectively. The median overall (OS) and progression-free survival (PFS) were 67 and 50 months, respectively. The 5-year OS rate was 89.6%. Recurrence occured in 24 (19.5%) patients. In univariate analyses tumor grade (p: 0.005), pelvic LN number (p: 0.041) and PaLN number (p: 0.004) were the factors that were significantly associated with PFS. Tumor grade and PaLN number were independently and significantly associated with PFS in multivariate analyses (p: 0.015 and p: 0.017, respectively). In OS analyses, age, tumor grade, presence of LVI, number of pelvic and PaLNs were the significantly associated factors (p < 0.05 for all). In multivariate analyses, age and PaLN number were independently and significantly associated with OS (p: 0.011 and p: 0.021, respectively).

CONCLUSIONS

The number and localizations of removed lymph nodes may have a survival affect in stage I EOC. We also think that this study may constitute a kernel point for larger prospective series on lymph node number and lymphatic regions.

A modified technique to perform para-aortic lymphadenectomy up to the renal vein

OBJECTIVE

To investigate the safety and feasibility of our modified technique to perform lymph node excision up to the renal vein in cases of gynecological cancer.

MATERIALS AND METHODS

87 patients with endometrial or ovarian neoplasms underwent laparoscopic para-aortic lymphadenectomy (LPAL) up to the left renal vein were enrolled prospectively. During surgery, the surgeon was positioned to the right side of the patient and an additional trocar was introduced into the upper right abdomen. The laparoscopic video screen was placed to the side of the patient's head. Three-fan retractor forceps were used to hold up the duodenum and small bowel. The rest of the procedure was the same as conventional LPAL.

RESULTS

The median operating time for LPAL was 72 min (range: 40-115 min) and the median estimated blood loss was 45 ml (range: 15-1000 mL). There were two cases of intra-operative vascular injury. The median number of retrieved para-aortic lymph nodes (PALNs) was 18 (range: 10-37). Of the 87 patients, 11 patients had positive PALNs. None of the cases required laparotomy.

CONCLUSION

Our findings demonstrate that our modified LPAL technique is feasible, reproducible, can achieve good exposure and reduces surgical difficulty.

PLAG1 silencing promotes cell chemosensitivity in ovarian cancer via the IGF2 signaling pathway

Ovarian cancer (OC) is one of the most lethal gynecological diseases. Novel prognostic biomarkers and therapeutic targets for OC are urgently required. The aim of this study was to investigate the mechanisms that govern how pleomorphic adenoma gene 1 (PLAG1) influences the biological processes and chemosensitivity of OC cells via the insulin‑like growth factor‑2 (IGF2) signaling pathway. Differentially expressed genes in OC were selected based on bioinformatics data. OC and adjacent tissue specimen were collected, followed by the determination of the expression of PLAG1 and IGF2 signaling pathway‑associated genes. The regulatory mechanisms of PLAG1 in OC cells were analyzed following treatment with pcDNA or small interfering RNA (siRNA), and included the assessment of cell proliferation, migration, invasion and cisplatin resistance. PLAG1 was identified as an upregulated gene in OC. OC tissues exhibited increased expression of PLAG1 and IGF2 compared with the controls. Moreover, PLAG1 was observed to positively regulate the IGF2 signaling pathway. The siRNA‑mediated silencing of PLAG1 resulted in decreased expression of IGF2, IGF1 receptor and insulin receptor substrate 1, as well as inhibited proliferation, migration, invasion and cisplatin resistance of OC cells. Furthermore, the effect of PLAG1 was dependent on IGF2. PLAG1 may therefore be considered as a possible target for the treatment of OC.

Incidence of Lymph Node Metastases in Apparent Early-Stage Low-Grade Epithelial Ovarian Cancer: A Comprehensive Review

Objectives

This study aimed to determine the incidence of lymph node (LN) metastases in presumed stage I-II low-grade epithelial ovarian cancer (EOC).

Methods

Eligible studies were identified from MEDLINE and EMBASE (time frame, 2015–1975), that analyzed patients with clinical or radiologic presumed early-stage EOC who underwent a complete pelvic and para-aortic lymphadenectomy as part of their surgical staging. The number and site of dissected and involved LNs and the correlation with overall outcome are analyzed. The termlow gradeand also the older termwell differentiatedwere used.

Results

Thirteen of 978 identified studies were selected, and 13 of 75 studies were identified as eligible. A total of 1403 patients were analyzed in these 13 retrospective studies. The final International Federation of Gynecology and Obstetrics staging after completed surgical staging was I to II in 912 patients (65%). A total of 338 patients (24%) had grade 1 tumors whereas 473 patients (34%) had grade 2, and 502 patients (36%) had grade 3 tumors. Systematic lymphadenectomy was performed in 1159 patients (83%), whereof 1142 (82%) were pelvic and para-aortic LN dissections.

In 185 patients (13%), an upstaging from an apparent clinical stage I-II to IIIC occurred because of LN involvement: 64 (35%) of the patients had only pelvic LNs metastases, 69 (37%) had only para-aortic LNs metastasis, and 51 (28%) had both a pelvic and para-aortic LN involvement. When analyzing only the patients with low-grade (grade 1 as the old classification) presumed early-stage disease (n = 273), only 8 patients (2.9%; range, 0–6.2) were identified with LNs metastases present.

Conclusions

The incidence of occult LN metastases in apparent early-stage low-grade EOC is 2.9% in a metaanalysis of retrospective studies. Future larger-scale prospectively assessed studies with established surgical quality of the LN dissection are warranted to establish the true incidence of LN metastasis in presumed early low-grade disease.

Near-infrared Fluorescence-guided Sentinel Node Mapping of the Ovary With Indocyanine Green in a Minimally Invasive Setting: A Feasible Study

Sentinel lymph node (SLN) mapping has increased its feasibility in both early-stage cervical and endometrial cancer. There are few SLN studies regarding the ovary because of the risk of tumor dissemination and perhaps because the ovary represents an inconvenient site for injection. In this preliminary study, we have shown the feasibility of SLN mapping of the ovary with indocyanine green during laparoscopic retroperitoneal aortic surgical staging. The 10 women who were included in this study underwent aortic with pelvic laparoscopic staging, which included SLN biopsy, extrafascial total hysterectomy, and bilateral salpingo-oophorectomy in case of an ovarian tumor. The fluorescent dye was injected on the dorsal and ventral side of the proper ovarian ligament and the suspensory ligament, close to the ovary and just underneath the peritoneum. In all cases except 1, SLNs were detected soon after the injection in the aortic compartment and in 3 cases also in the common iliac region. Only 1 intraoperative complication occurred: a superficial lesion of the vena cava that was recovered with a laparoscopic suture. Laparoscopic ovarian SLN mapping performed by means of an injection of indocyanine green fluorescent tracer in the ovarian ligaments seems feasible and promising. Further investigation are encouraged and necessary to evaluate the possible applications of this new technique for staging patients with early-stage ovarian cancer.

Prevalence and distribution pattern of nodal metastases in advanced ovarian cancer

The objective of this study was to examine the relevance of pelvic and para-aortic lymph node involvement and the tumour characteristics affecting nodal metastases and survival in primary advanced ovarian cancer. A total of 130 consecutive patients were retrospectively investigated. All the patients received stage-related surgery with pelvic and para-aortic lymphadenectomy. The median follow-up was 53.5 months. The clinicopathological parameters and distribution pattern of nodal metastases were evaluated. Lymph node metastases were detectable in 74.62% of the cases. Overall, both pelvic and para-aortic nodes were affected in 35.9% of the patients, whereas 13.3% had metastases only in the pelvic and 13.3% only in the para-aortic lymph nodes. Histological grade 1/2 and 3, serous and endometrioid histology were independent predictors of nodal metastasis. Serous and endometrioid cancers have shown a predilection for metastasis to the pelvic lymph nodes alone, both to the pelvic and the para-aortic nodes, or the para-aortic nodes alone. Overall survival was significantly positively affected by serous histology with positive nodes (P=0.043). It is crucial to investigate the risk factors and metastatic patterns of such patients in a multicenter analysis to evaluate individual subgroups. Prospective studies are required to investigate the prognostic effect of lymphadenectomy in advanced ovarian cancer and its association with histology and distribution pattern of nodal metastasis.

Role of a Double Docking to Improve Lymph Node Dissection: When Robotically Assisted Laparoscopy for Para-aortic Lymphadenectomy Is Associated to a Pelvic Procedure

Objective

The objective of this study was to demonstrate that robotically assisted laparoscopy for aortic lymph node dissection was improved when double docking (DD) of the Da Vinci system is used for combined surgical procedures [defined by the combination of a pelvic procedure and a para-aortic lymphadenectomy (PAL)].

Methods

From February 2007 to February 2013, 41 patients underwent combined procedures including PAL up to the left renal vein in 2 cancer centers. We used 2 different approaches as follows: a single docking (SD) of the Da Vinci system (transperitoneal PAL and pelvic surgery) during the first period (22 patients) and a DD during the second period (19 patients). We recorded retrospectively the lymph node count (main criteria), operative time, estimated blood loss, hospital stay, and postoperative complications.

Results

We observed a statistical difference between SD and DD concerning aortic lymph node count (5.86 vs 10.89,P< 0.005). Operative time is longer in the DD group (326.1 vs 239.4 minutes,P< 0.05). No difference was observed concerning estimated blood loss. Hospital stay was longer in the DD group (4.9 vs 3.2 days,P< 0.05). Only 1 conversion to open was described in the SD group.

Conclusions

In our experience of robotically assisted laparoscopy, when PAL is combined to a pelvic procedure, the use of a DD seems to improve aortic lymph node count.

Despite a longer operative time compared to SD, DD seems to be a good solution to combine the advantages of robotic assistance to our quality criteria of aortic dissection.

Synopsis

We compare 2 techniques to realize robotic assisted para-aortic lymphadenectomy combined with pelvic procedure. Double docking seems to improve histological results compared to single docking.

Impact of guideline adherence on patient outcomes in early-stage epithelial ovarian cancer

AIM

The aim of this study was to evaluate the effects of adherence to National Comprehensive Cancer Network (NCCN) guidelines on survival outcomes in patients with early-stage epithelial ovarian cancer.

METHODS

Our institutional cancer registry data on 266 patients with Stage I epithelial ovarian cancer was reviewed retrospectively and compliance with treatment guidelines for surgery and adjuvant treatment was determined. Patients were categorized according to adherence or non-adherence. The primary endpoints were recurrence-free survival and disease-specific survival. Hazard ratios (HRs) for survival were estimated with a Cox proportional hazards model.

RESULTS

Of the 266 patients, 71 (26.7%) underwent adequate surgical staging in accordance with the guidelines. The guidelines for adjuvant chemotherapy were followed adequately in all 71 patients that were adherent to surgical staging and in 163 of the 195 patients with non-adherence to surgical staging (83.6%). Multivariate analysis, adjusted for prognostic factors, identified higher recurrence-free survival (HR, 0.36; 95% CI, 0.15-0.88) and disease-specific survival (HR, 0.42; 95% CI, 0.16-1.12) among patients whose treatment adhered to both surgical and chemotherapy guidelines, although disease-specific survival was not statistically significant. When excluding clear cell histology from the cohort, the guideline-adherent group had significantly better disease-specific survival than the non-adherent group (HR, 0.13; 95% CI, 0.02-0.94).

CONCLUSION

The results of this study suggest that adherence to NCCN guidelines may improve survival outcomes in patients with early-stage epithelial ovarian cancer, particularly in cases other than clear cell histology.

Addition of parity to the risk of malignancy index score in evaluating adnexal masses

OBJECTIVE

The aim of our study was to evaluate the individual contribution of parity when incorporated as another parameter into the four risk of malignancy indices (RMI 1-4) to differentiate noninvasive benign lesions from invasive malignant ovarian lesions.

MATERIALS AND METHODS

After calculating RMI 1-4 for each patient included in this study, the resulting RMI scores were further multiplied by the parity score (P) of each patient to calculate the RMI parity (RMIP) score.

RESULTS

A cutoff value of 300 for RMIP 1 yielded 95.0% specificity, 97.4% negative predictive value (NPV), 88.5% sensitivity, and 79.3% positive predictive value (PPV) and performed better than RMI 1 in the preoperative diagnosis of invasive malignant lesions. RMIP 2 with a cutoff value of 400 yielded 95.0% specificity, 97.4% NPV, 88.5% sensitivity, and 79.3% PPV, and it also performed better than RMI 2. A cutoff value of 400 for RMIP 3 provided 97.5% specificity, 97.5% NPV, 88.5% sensitivity, and 88.5% PPV and performed better than RMI 3. However, a cutoff value of 400 for RMIP 4 provided 90.0% specificity, 97.3% NPV, 88.5% sensitivity, and 65.7% PPV but did not perform better than RMI 4 in the preoperative diagnosis of invasive malignant lesions.

CONCLUSION

RMIP 1-3 scales were more reliable tools for the preoperative diagnosis of invasive adnexal masses compared with the traditional RMI 1-3 scales.

Clinical epidemiology of epithelial ovarian cancer in the UK

Epithelial ovarian cancer is the fifth commonest cancer among women and the leading cause of gynecological cancer death in the UK. Most women present with advanced disease, mainly because the nonspecific nature of the symptoms lead to diagnostic delays. Recent data have shown a fall in ovarian cancer mortality rates in the UK, but rates are still higher when compared to other European countries or the USA. In addition, surgeons in the UK achieve on average lower optimal surgical cytoreduction rates in patients with advanced ovarian cancer. Despite a wealth of information on epidemiological risk factors, the pathogenesis of epithelial ovarian cancer remains largely unknown. This review presents the most recent data on incidence, mortality, and survival for epithelial ovarian cancer in the UK. Time trends, trends by age, international comparisons, and regional variation in incidence, survival, and mortality are presented within the context of a major reorganization of cancer services that took place in the UK over 10 years ago. Centralization of cancer services has meant that women with ovarian cancer receive treatment in specialist Cancer Centers.

The prognostic significance of preoperative leukocytosis in epithelial ovarian carcinoma: a retrospective cohort study

OBJECTIVE

Preoperative leukocytosis is known to be a negative prognostic factor for several gynecologic malignancies, but its relationship with epithelial ovarian carcinoma (EOC) is unknown. We sought to evaluate the prognostic implications of preoperative leukocytosis for women with EOC.

METHODS

We retrospectively reviewed the medical records of patients who underwent primary debulking surgery and adjuvant platinum-based chemotherapy for EOC between January 1993 and October 2011. Associations between leukocytosis and recurrence-free survival (RFS) and overall survival (OS) were determined by univariate analyses. Multivariate Cox proportional hazards regression was used to identify independent prognostic factors for RFS and OS.

RESULTS

Of 155 women, 23 (14.8%) had leukocytosis and 132 (85.2%) did not have leukocytosis. RFS and OS were significantly shorter for women with leukocytosis than for women without leukocytosis (P=0.009 and P<0.0001, respectively). The mortality rate was also higher among women with leukocytosis (P<0.0001). Multivariate analysis revealed that preoperative leukocytosis (hazard ratio [HR]: 2.15; 95% confidence interval [CI]: 1.55-4.41; P=0.009), advanced stage (HR: 3.12; 95% CI: 1.44-6.75; P=0.004), and optimal cytoreduction (HR: 0.38; 95% CI: 0.14-0.70; P=0.031) were independent prognostic factors for RFS. Additionally, preoperative leukocytosis was independently associated with decreased OS (HR: 7.66; 95% CI: 2.78-21.16; P<0.0001).

CONCLUSIONS

Among women with EOC, preoperative leukocytosis might be an independent prognostic factor for RFS and OS. A larger-scaled, prospective study is needed to verify these results.

Surgical anatomy of the common iliac veins during para-aortic and pelvic lymphadenectomy for gynecologic cancer

OBJECTIVE

Compression of the left common iliac vein between the right common iliac artery and the vertebrae is known to be associated with the occurrence of left iliofemoral deep vein thrombosis (DVT). In this study, we described the variability in vascular anatomy of the common iliac veins and evaluated the relationship between the degree of iliac vein compression and the presence of DVT using the data from surgeries for gynecologic cancer.

METHODS

The anatomical variations and the degrees of iliac vein compression were determined in 119 patients who underwent systematic para-aortic and pelvic lymphadenectomy during surgery for primary gynecologic cancer. Their medical records were reviewed with respect to patient-, disease-, and surgery-related data.

RESULTS

THE DEGREES OF COMMON ILIAC VEIN COMPRESSION WERE CLASSIFIED INTO THREE GRADES: grade A (n=28, 23.5%), with a calculated percentage of 0%-25% compression; grade B (n=47, 39.5%), with a calculated percentage of 26%-50% compression; and grade C (n=44, 37%), with a calculated percentage of more than 50% compression. Seven patients (5.9%) had common iliac veins with anomalous anatomies; three were divided into small caliber vessels, two with a flattened structure, and two had double inferior vena cavae. The presence of DVT was associated with the elevated D-dimer levels but not with the degree of iliac vein compression in this series.

CONCLUSION

Although severe compression of the common iliac veins was frequently observed, the degree of compression might not be associated with DVT in surgical patients with gynecologic cancer. Anomalous anatomies of common iliac veins should be considered during systematic para-aortic and pelvic lymphadenectomy in the gynecologic cancer patients.

Laparoscopic management of a strangulated internal hernia underneath the left external iliac artery

INTRODUCTION

Internal herniation of a small bowel behind pelvic vessels is a rare complication seen after pelvic lymphadenectomy.

PRESENTATION OF CASE

A 56-year-old woman was operated due to a gynecological cancer. 4 years thereafter she presented with a 2 days history of abdominal pain and vomiting. Clinical and radiological findings indicated a small bowel obstruction. A loop of small bowel had herniated behind the left external iliac artery. Using laparoscopic technique the herniated bowel was reduced. Due to limited peritoneum around the area and skeletonized vessel, we decided not to do any repair of the hernia orifice. The postoperative recovery was uneventful, bowel activity returned to normal and she was discharged the next day. Follow-up was done at 1 month and the latest at 10 months. She didn't experience pain or discomfort after the operation.

DISCUSSION

Due to limited peritoneum around the skeletonized vessel, we decided to leave the hernia orifice unrepaired. We found it hazardous to do any direct suture of the orifice or use a free peritoneal graft to repair the defect as the fibrosis and inflammatory process might have compromised the artery or the vein. A longer follow-up of the patient is needed to clearly conclude if this simple procedure has been sufficient. We agreed that if the patient would experience any sign of recurrence and need another operation we would close the defect at that time.

CONCLUSION

4 years after pelvic lymphadenectomy a small bowel herniation behind an external iliac artery occurred. The patient was successfully treated with reduction of the small bowel using laparoscopic technique. A quick recovery with minimal discomfort and no sign of recurrence after 10 months made our approach an acceptable surgical option.
