Comparing proficiency of obstetrics and gynaecology trainees with general surgery trainees using simulated laparoscopic tasks in Health Education England, North-West: a prospective observational study.

BACKGROUND: Training programmes for obstetrics and gynaecology (O&G) and general surgery (GS) vary significantly, but both require proficiency in laparoscopic skills. We sought to determine performance in each specialty. DESIGN: Prospective, observational study. SETTING: Health Education England North-West, UK. PARTICIPANTS: 47 surgical trainees (24 O&G and 23 GS) were subdivided into four groups: 11 junior O&G, 13 senior O&G, 11 junior GS and 12 senior GS trainees. OBJECTIVES: Trainees were tested on four simulated laparoscopic tasks: laparoscopic camera navigation (LCN), hand-eye coordination (HEC), bimanual coordination (BMC) and suturing with intracorporeal knot tying (suturing). RESULTS: O&G trainees completed LCN (p<0.001), HEC (p<0.001) and BMC (p<0.001) significantly slower than GS trainees. Furthermore, O&G found fewer number of targets in LCN (p=0.001) and dropped a greater number of pins than the GS trainees in BMC (p=0.04). In all three tasks, there were significant differences between O&G and GS trainees but no difference between the junior and senior groups within each specialty. Performance in suturing also varied by specialty; senior O&G trainees scored significantly lower than senior GS trainees (O&G 11.4±4.4 vs GS 16.8±2.1, p=0.03). Whilst suturing scores improved with seniority among O&G trainees, there was no difference between the junior and senior GS trainees (senior O&G 11.4±4.4 vs junior O&G 3.6±2.1, p=0.004). DISCUSSION: GS trainees performed better than O&G trainees in core laparoscopic skills, and the structure of O&G training may require modification. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Registry (NCT05116332).

Adenomyosis and infertility: the role of the junctional zone.

OBJECTIVE: Adenomyosis is a benign uterine disorder characterized by the invasion of the endometrium within the myometrium, starting from the junctional zone (JZ), the inner hormone dependent layer of the myometrium that plays an important role in sperm transport, implantation and placentation. The resulting histological abnormalities and functional defects may represent the pathogenic substrate for infertility and pregnancy complications. The objective of this paper is to review the literature to evaluate the correlation between inner myometrium alterations and infertility and to assess the role of JZ in the origin of adverse obstetric outcomes of both spontaneous and in vitro fertilization (IVF) pregnancies. METHODS: we searched Pubmed for all original and review articles in the English language from January1962 until December 2019, using the MeSH terms of 'adenomyosis', 'junctional zone', combined with 'infertility', 'obstetrical outcomes', 'spontaneous conception', 'in vitro fertilization' and 'classification'. The review was divided into three sections to assess this pathogenic correlation, evaluating also the importance of classification of the disease. RESULTS AND CONCLUSIONS: Absent or incomplete remodeling of the JZ can affect uterine peristalsis, alter vascular plasticity of the spiral arteries and activate inflammatory pathways, all related to adverse obstetric outcomes. Despite these observations, there is still limited evidence whether adenomyosis is a cause of infertility. However, it is reasonable to screen patients for adenomyosis, to consider pregnant women with diffuse adenomyosis at high risk of adverse obstetric outcomes, and to evaluate the importance of a noninvasive validated classification in the management of women with adenomyosis.

Pudendal Neurolysis: 6-Step Laparoscopic Approach.

OBJECTIVE: To demonstrate the safety and feasibility of the laparoscopic approach to perform pudendal neurolysis in a case of pudendal nerve entrapment syndrome [1-3]. DESIGN: A video tutorial that highlights the laparoscopic steps to performing pudendal neurolysis, with a focus on the main anatomic landmarks [4,5]. SETTING: A tertiary care regional hospital. INTERVENTIONS: This video shows a 6-step approach to laparoscopic pudendal neurolysis for the treatment of pudendal nerve entrapment between the sacrospinous and sacrotuberous ligaments [2,6-8]. Step 1: Identification of the umbilical artery. Step 2: Dissection and development of the lateral paravesical space until the pelvic floor. Step 3: Identification of the arcus tendineus of the endopelvic fascia. Step 4: Identification of the ischial spine and the sacrospinous ligament covered by the coccygeus muscle. Step 5: Coagulation and section of the coccygeus muscle and the sacrospinous ligament. Step 6: Medialization of the pudendal nerve until its entrance into the Alcock canal. CONCLUSION: This video demonstrates the safety, feasibility, and reproducibility of laparoscopic pudendal neurolysis in 6 steps. A minimally invasive approach is adequate to treat the pudendal compression until the Alcock canal [2].

Pathophysiologic mechanisms by which adenomyosis predisposes to postpartum haemorrhage and other obstetric complications.

Adenomyosis is characterized by the presence of ectopic endometrium within the myometrium. This features lead to structural changes in the surrounding myometrium and endometrium resulting also in functional changes. Alterations in the myometrium are suspected to lead to defective remodeling of spiral arteries during the early stages of decidualization resulting in altered vascular resistance and defective placentation. These alterations could play a common part in the association between adenomyosis and major obstetric complications. Latest epidemiological studies show that adenomyosis is associated with preterm birth, preeclampsia, IUGR and increased caesarean section rates, but very little is known of any underlying mechanism linking postpartum hemorrhage and adenomyosis. It is our opinion that adenomyosis may increase the risk of postpartum hemorrhage through several mechanisms that will be further clarified. Women with adenomyosis may require specific management during pregnancy and may benefit from wider understanding of the pathological mechanisms associated with this disease process.

Bowel Endometriosis: Current Perspectives on Diagnosis and Treatment.

Endometriosis is a chronic condition primarily affecting young women of reproductive age. Although some women with bowel endometriosis may be asymptomatic patients typically report a myriad of symptoms such as alteration in bowel habits (constipation/diarrhoea) dyschezia, dysmenorrhoea and dyspareunia in addition to infertility. To date, there are no clear guidelines on the evaluation of patients with suspected bowel endometriosis. Several techniques have been proposed including transvaginal and/or transrectal ultrasonography, magnetic resonance imaging, and double-contrast barium enema. These different imaging modalities provide greater information regarding presence, location and extent of endometriosis ensuring patients are adequately informed whilst also optimizing preoperative planning. In cases where surgical management is indicated, surgery should be performed by experienced surgeons, in centres with access to multidisciplinary care. Treatment should be tailored according to patient symptoms and wishes with a view to excising as much disease as possible, whilst at the same time preserving organ function. In this review article current perspectives on diagnosis and management of bowel endometriosis are discussed.

Sacrohysteropexy: A Way to Spare the Uterus.

STUDY OBJECTIVE: To show the safety and feasibility of laparoscopic sacrohysteropexy for treating uterine prolapse. DESIGN: An educational video to explain the laparoscopic steps of this procedure by focusing on the main anatomic landmarks and on tips and tricks to avoid complications. SETTING: A tertiary care university hospital. INTERVENTIONS: Laparoscopic sacropexy with uterus preservation for grade 3 apical defect. CONCLUSION: This video shows a stepwise approach to laparoscopic sacrohysteropexy demonstrating its feasibility and safety. There is a wide choice of surgical procedures and approaches focused on pelvic organ prolapse repair. Since many years, uterine prolapse has been an indication for hysterectomy, regardless of the occurrence of uterine disease and patients' desires. With the introduction of minimally invasive surgery, the uterine-sparing procedures are being increasingly taken into account, especially in young women [1]. Sacrohysteropexy is a uterus-sparing procedure that allows for a reduction in operating time, intraoperative blood loss, mesh-related complications, and surgical costs [2]. Furthermore, this technique has a high success rate with an objective cure rate of 100% for the apical compartment and 80% for all compartments and does not seem to increase the pelvic organ prolapse recurrence rate [3]. Sacropexy is not a life-threatening procedure, but its main objective is to restore functional anatomy with the primary goal of improvement in patient's quality of life. Moreove, no difference has been found with or without uterus preservation in term of postoperative recurrence rate or ent's quality of life [4]. However, high patient satisfaction has been recently reported; therefore, uterine preservation should be considered during patient's counseling.

Laparoscopic Dissection of the Pelvic Ureter: Rules of Engagement.

STUDY OBJECTIVE: To point out the relevant anatomy of the ureter and to demonstrate its rules of dissection. DESIGN: An educational video to explain how to use ureteral relevant anatomy and the principle of dissection to perform safe ureterolysis during laparoscopic procedures. SETTING: A tertiary care university hospital and endometriosis referential center. INTERVENTIONS: Anatomic keynotes of the ureter and examples of ureterolysis. CONCLUSION: This video shows the feasibility of laparoscopic ureteral dissection and provides safety rules to perform ureterolysis. Identification and dissection of the ureter should be part of all gynecologic surgeons' background to reduce the risk of complications [1]. Knowledge of anatomy plays a pivotal role, allowing the surgeon to keep the ureter at a distance and minimizing the need for ureterolysis. Unfortunately, the need for ureteral dissection is not always predictable preoperatively, and gynecologic surgeons need to master this technique, especially when approaching more complex procedures such as endometriosis [2]. An implicit risk of damage cannot be denied when performing ureterolysis; therefore, the ureter should be dissected only when strictly necessary and handled with care to minimize the use of energy [3].

Standard Approach to Urinary Bladder Endometriosis.

STUDY OBJECTIVE: Urinary endometriosis accounts for 1% of all endometriosis where the bladder is the most affected organ. Although the laparoscopic removal of bladder endometriosis has been demonstrated to be effective in terms of symptom relief with a low recurrence rate, there is no standardized technique. Partial cystectomy allows the complete removal of the disease and is associated with low intra- and postoperative complications. Here we describe a stepwise approach to a rare case of a large endometriosis nodule affecting the trigone of the urinary bladder. DESIGN: Step-by-step video explanation of a large endometriotic nodule excision (Canadian Task Force classification III). SETTING: IRCAD AMITS - Barretos | Hospital Pio XVI. The video was approved by the local institutional review board. PATIENT: A 31-year-old woman. INTERVENTION: Laparoscopic approach for bladder endometriosis. MEASUREMENTS AND MAIN RESULTS: We present a case of a 31-year-old woman who complained of dysuria and hematuria with a bladder nodule of 3 cm affecting the bladder trigone. Laparoscopic complete excision of the nodule was performed. Laparoscopy began with full inspection of the pelvic and abdominal cavity. Vaginal examination under laparoscopic view helped to determinate the dimensions of the bladder nodule. Strategy consisted of bilateral dissection of the paravesical fossae and the identification of both uterine arteries and ureters. The bladder was slowly dissected from the uterine isthmus and was intentionally opened, thus helping the surgeons to identify the lateral and lower limits of the nodule and its proximity to both ureters. Bilateral double J stents were previously placed to guide the excision and further suture. Once the nodule was removed, the remaining wall consisted of the lower aspect of the trigone, both medial lower parts of the ureter, and the apex of the bladder. Suturing was performed in 2 steps. A simple monofilament interrupted suture was applied vertically at the lower wall between both ureters. The same technique was applied horizontally on the bladder dome. Pressure test demonstrated adequate correction. The patient was discharged 2 days later with a bladder catheter and double J stent. After 15 days, both indwelling catheter and ureteric stent were removed, and patient was submitted to a cystogram where no leakage was found. If a leakage had been found on the cystogram, the bladder should be allowed an additional week of continuous drainage. Early follow-up demonstrated a lower bladder capacity that was resolved within 6 months. After a 1-year follow-up the patient had no symptoms and demonstrated no recurrence. She is now 20 weeks pregnant with no need of assisted reproductive methods. CONCLUSION: The technique showed in the video demonstrates the feasibility of a laparoscopic approach for bladder endometriosis. Furthermore, the laparoscopic approach allowed the removal of the large nodule, reducing the risk of small bladder symptoms.

Effect of Anterior Compartment Endometriosis Excision on Infertility.

BACKGROUND AND OBJECTIVES: Laparoscopic surgical excision of bladder nodules has been demonstrated to be effective in relieving associated painful symptoms; the data are lacking concerning the impact of anterior compartment endometriosis on infertility. We conducted this study to evaluate whether or not the surgical excision of deep endometriosis affecting the anterior compartment plays a role in restoring fertility. METHODS: This multicentre, retrospective study included a group of 55 patients presenting with otherwise-unexplained infertility who had undergone laparoscopic excision of anterior compartment endometriosis with histological confirmation. Patient medical records and operative reports were reviewed. Telephone interviews were conducted for long-term followup of fertility outcomes. RESULTS: The pregnancy rate following surgical excision of endometriotic lesions was 44% (n = 11) among those with anterior compartment involvement alone and 50% (n = 15) in case of posterior lesions association without any significant difference. The symptoms related to bladder endometriosis resolved in the 84.2% of the cases with a recurrence rate of 1.8% at the 2-year followup not requiring further surgery. CONCLUSION: Laparoscopic excision of anterior compartment endometriosis is effective in restoring fertility in patients with otherwise-unexplained infertility and in treating endometriosis-related symptoms.

Does the Number of Neoadjuvant Chemotherapy Cycles before Interval Debulking Surgery Influence Survival in Advanced Ovarian Cancer?

OBJECTIVE: To evaluate the overall survival (OS) of patients with initially inoperable advanced ovarian cancer, tubal carcinoma, or primary peritoneal carcinoma of stages III or IV undergoing neoadjuvant chemotherapy (NAC) followed by cytoreductive surgery, according to the number of cycles performed. METHODS: This retrospective study was conducted in three main oncology centres in the east of France, reviewing the charts of all patients who underwent NAC between January 1, 1998 and October 31, 2012. We performed an OS analysis using multivariate Cox regression models adjusted for potential confounders. We also analysed progression-free survival (PFS) as well as chemotherapy- and surgery-related morbidity. RESULTS: Of the 204 patients included, 75 (36.8%) underwent ≤4 NAC cycles and 129 (63.2%) ≥5 NAC cycles. Characteristic data were similar in the two groups. Five-year OS was 35.0 and 25.8%, respectively. This difference was non-significant [HR = 1.06 (0.70-1.59), p = 0.79]. We also found no differences in PFS or morbidity between the two groups. CONCLUSIONS: The number of NAC cycles does not seem to play a role in the OS of patients with advanced ovarian cancer. Further evidence and prospective data are needed to assess the value of a high/low number of NAC cycles among these patients.

Segmental and Discoid Resection are Preferential to Bowel Shaving for Medium-Term Symptomatic Relief in Patients With Bowel Endometriosis.

OBJECTIVE: To evaluate and compare medium-term clinical outcomes and recurrence rates in the laparoscopic surgical management of bowel endometriosis comparing 3 different surgical techniques (shaving, discoid, and segmental resection). DESIGN: Retrospective study (Canadian Task Force classification II-2). SETTING: Endometriosis tertiary referral center. PATIENTS: A retrospective cohort of 106 patients with histological confirmation of bowel endometriosis undergoing laparoscopic surgical treatment between January 1, 2010, and September 1, 2012. INTERVENTION: Assessment of laparoscopic bowel shaving, discoid or segmental resection for the treatment of painful symptoms related to deep endometriosis (DE) involving the bowel with 24 months of follow-up. MEASUREMENTS AND MAIN RESULTS: A total of 92 patients were included in the study and were divided into 3 groups according to the surgical procedure performed (shaving, n = 47; discoid resection, n = 15; segmental resection, n = 30). All symptoms improved significantly in the immediate postoperative follow-up, with significant reduction in all visual analog scale scores for pain. Compared with the discoid resection and segmental resection groups, the shaving group had a significantly higher rate of medium-term recurrence of dysmenorrhea and dyspareunia. Furthermore, the shaving group had a higher rate of reintervention for recurrent DE lesions compared with the segmental resection group (27.6% vs 6.6%; relative risk [RR], 4.14; 95% confidence interval [CI], 1.0-17.1). Postoperative complication rates were similar across all 3 groups with a rate of major complications of 4.2% in the shaving group, 6.6% in the discoid resection group, and 6.6% in the segmental resection group. According to our data, the patients with a nodule >3 cm had an RR of 2.5 (95% CI, 1.66-3.99) of requiring bowel resection. CONCLUSION: All 3 treatment modalities are effective in terms of immediate symptom relief with acceptable complication rates. However, significantly higher rates of symptom recurrence and reintervention were noted in the shaving group, whereas segmental resection is more likely to be indicated in cases of large nodules.

Impact of Laparoscopic Surgical Management of Deep Endometriosis on Pregnancy Rate.

STUDY OBJECTIVE: To evaluate the impact of laparoscopic excision of lesions on deep endometriosis-related infertility. DESIGN: Retrospective study. SETTING: Endometriosis tertiary referral center (Canadian Task Force II-2). PATIENTS: A group of 115 patients who had undergone laparoscopic surgery for infertility with histologic confirmation of deep endometriosis. INTERVENTIONS: Patient medical records and operative reports were reviewed. Telephone interviews were conducted for long-term follow-up of fertility outcomes. MEASUREMENTS AND MAIN RESULTS: Evaluation of fertility outcome after laparoscopic treatment of deep endometriosis by spontaneous conception and by assisted reproductive technology (ART) correlated with lesion number, size, and location (anterior, posterolateral, pouch of Douglas, and multiple locations). After a mean follow-up of 22 months the overall pregnancy rate was 54.78% (n = 63) with a live-birth rate of 42.6% (n = 49). Among those patients given the chance to conceive spontaneously (n = 70), the overall pregnancy rate was 60% (n = 42): 38.5% (n = 27) spontaneously and 21.4% (n = 15) by ART. The removal of multiple lesions was associated with a higher pregnancy rate after surgery. When comparing isolated lesion size and disease location, there was no difference in pregnancy rate. Furthermore, those patients who underwent surgical eradication of the disease for the first time had a higher pregnancy rate (odds ratio, 4.18). CONCLUSION: This study demonstrates that laparoscopic excision of deep endometriosis enhances pregnancy rate, by both spontaneous conception and ART. First surgical treatment of multiple lesions was associated with higher pregnancy rates, whereas isolated lesions influenced the pregnancy rate irrespective of their location and size.

Adolescent Endometriosis: Report of a Series of 55 Cases With a Focus on Clinical Presentation and Long-Term Issues.

STUDY OBJECTIVE: To report the clinical presentation and long-term issues of adolescent endometriosis. DESIGN: Retrospective cohort study. SETTING: Single private clinical center, Bordeaux, France. PATIENTS: Adolescents with a confirmed diagnosis of endometriosis. INTERVENTIONS: Surgical excision or ablation or lesions performed at laparoscopy. MEASUREMENTS AND MAIN RESULTS: Fifty-five adolescents, ages from 12 to 19 years (mean age 17.8), who were diagnosed with endometriosis from March 1998 to April 2013 were included in the study. Pain of various types was the leading symptom in all patients, except 2. Twenty-three patients had an adnexal mass identified preoperatively, and 5 had an associated infertility issue at the time of diagnostic laparoscopy. Four patients had an associated genital malformation. Fifty-one percent of the patients had a history of appendectomy. A familial history of endometriosis was reported by 19 patients (34.5%), with a first-degree relative affected in 14 cases (25.45%), and 47.3% of patients were smoking at least 5 cigarettes a day. Superficial implants was encountered in 31 cases (56.4%), endometriomas in 18 cases (32.72%), and deep infiltrating endometriosis (DIE) in 6 cases (10.90%). Sixty percent of patients were scored as stages I to II and 40% as stages III to IV. Five patients were lost to follow-up, and 37 had a follow-up ranging from 36 to 315 months (mean follow-up 125.5 months). Among the 50 patients not lost to follow-up, 13 (26%) had either no pain, or improved and had acceptable pain with medical treatment. Seventeen patients of the 50 adolescents not lost to follow-up (34%) underwent a repeat laparoscopy. A subsequent laparoscopic and/or magnetic resonance imaging scan was performed in 35 patients because of persistent pain. Among these, there was 12 endometriomas (7 recurrences) and 12 DIEs (3 recurrences), giving recurrence rates for endometriomas and DIEs of 36.84% and 50%, respectively. During the study, 18 patients wished to have a child. Thirteen had a delivery (72.2%), and 9 pregnancies occurred in patients who initially presented with stage I to II endometriosis. Of the 11 patients who had subfertility, 6 successfully conceived (54.5%). CONCLUSIONS: Adolescent endometriosis is not a rare condition. In our study a familial history was reported in more than one-third of patients. Among those patients treated for DIE, there was a trend for higher rates of recurrences (symptoms or lesions) that required repeat laparoscopy. However, the impact on subsequent fertility appeared to have been limited.

Hysteroscopic Endometrial Resection Versus Laparoscopic Supracervical Hysterectomy for Abnormal Uterine Bleeding: Long-term Follow-up of a Randomized Trial.

STUDY OBJECTIVE: To compare long-term efficacy of laparoscopic supracervical hysterectomy (LSH) and hysteroscopic endometrial ablation (HEA) in treating persistent abnormal uterine bleeding. DESIGN: Canadian Task Force II-2. SETTING: University hospital. PATIENTS: One hundred fifty-three women treated for abnormal uterine bleeding by LSH or HEA. INTERVENTION: Long-term follow-up assessment of reintervention rate and quality of life (QoL) using the Quality Metric's Health Survey Short Form 12. MEASUREMENT AND MAIN RESULTS: This study is the long-term follow-up of a randomized control trial conducted in 2003 comparing LSH and HEA in terms of reoperation rate and QoL. Starting from November 2010 all patients included in the first trial were invited to participate in this study and clinically evaluated through vaginal examination and transvaginal ultrasound. After a mean follow-up of 14.4 years, 29% of patients (20/71) treated with HEA underwent further surgery, whereas no patients after LSH had symptom recurrence. The reintervention rate was significantly higher in the HEA group (p < .0001), with a relative risk of 1.39 (95% confidence interval, 1.20-1.61). The assessment of QoL demonstrated a higher score, in both physical and mental components, in the LSH group (p < .0001). CONCLUSION: The lower reintervention rate and the better physical and mental health scores make LSH a more suitable procedure to treat recurrent abnormal uterine bleeding when compared with HEA.

Step-by-step Type C Laparoscopic Radical Hysterectomy With Nerve-sparing Approach.

STUDY OBJECTIVE: To show the laparoscopic technique to perform type C radical hysterectomy with a nerve-sparing approach and pelvic lymphadenectomy. DESIGN: Educational video with step-by-step explanation of the technique using videos and pictures to highlight the anatomic landmark that guides the procedure. SETTING: The goal of this procedure is to enlarge the resection of the paracervix at the junction with internal iliac vascular system, leaving the neural part of the structure under the deep uterine vein untouched. Type C consists in the resection of the uterosacral ligament at the rectum level and the vesicouterine ligament at the bladder level. The ureter is mobilized completely, and 15 to 20 mm of the vagina from the tumor or cervix is resected. Performing such an enlarged hysterectomy, the preservation of the nerve supply to the bladder is crucial, leading to the creation of the subclasses. Type C1 conserves a nerve-sparing approach remaining above the deep uterine vein, whereas in type C2 a resection beyond this landmark including the neural part of the paracervix is performed. INTERVENTIONS: Total laparoscopic type C1 radical hysterectomy with pelvic lymphadenectomy. CONCLUSION: This video shows the feasibility of type C radical hysterectomy through a minimally invasive approach. The possibility to perform this type of procedure laparoscopically matches with the more conservative approach to cervical cancer, bringing all the advantages of this technique into this field of gynecologic surgery.

Is ileostomy always necessary following rectal resection for deep infiltrating endometriosis?

OBJECTIVE: To verify the hypothesis that in most patients bowel segmental resection to treat endometriosis can be safely performed without creation of a stoma and to discuss the limitations of this statement. DESIGN: Retrospective study (Canadian Task Force classification III). SETTING: Tertiary referral center. PATIENTS: Forty-one women with sigmoid and rectal endometriotic lesions who underwent segmental resection. INTERVENTION: Segmental resection procedures performed between 2004 and 2011. Patient demographic, operative, and postoperative data were compared. MEASUREMENTS AND MAIN RESULTS: Sigmoid resection was performed in 6 patients (15%), and rectal anterior resection in 35 patients (high in 21 patients [51%], and low, i.e., <10 cm from the anal verge, in 14 [34%]). In 4 patients a temporary ileostomy was created. There was 1 anastomotic leak (2.4%), in a patient with an unprotected anastomosis, which was treated via laparoscopic surgery and creation of a temporary ileostomy. Other postoperative complications included hemoperitoneum, pelvic abscess, pelvic collection, and a ureteral vaginal fistula, in 1 patient each (all 2.4%). CONCLUSION: A protective stoma may be averted in low anastomosis if it is >5 cm from the anal verge and there are no adverse intraoperative events.

Comparison between transperitoneal and extraperitoneal laparoscopic paraaortic lymphadenectomy in gynecologic malignancies.

STUDY OBJECTIVE: Two validated laparoscopic approaches for para-aortic lymphadenectomy (PAL) exist: the transperitoneal and the extraperitoneal. The aim of this study was to compare the surgical outcomes of both approaches. DESIGN: A retrospective review of all patients who underwent laparoscopic PAL for a gynecologic malignancy between January 2008 and October 2013. SETTING: University Hospital. PATIENTS: Two patients groups were compared: transperitoneal (n = 51) and extraperitoneal (n = 21). INTERVENTIONS: Paraaortic lymphadenectomy. MEASUREMENTS AND MAIN RESULTS: The χ(2) test, Fisher's exact test, or Student's t-test were used for univariate analysis and a stepwise logistic regression for multivariate analysis. The threshold of statistical significance was set at 0.05. All patient characteristics were similar between the 2 groups (p > .05 for all variables). There was only 1 (1.3%) conversion to laparotomy encountered in the transperitoneal PAL group and 3 conversions from extraperitoneal to transperitoneal PAL (14.2%). In 1 case of extraperitoneal PAL, the procedure was abandoned because of inadequate equipment (body mass index 48 kg/m(2)). The mean duration of surgery was longer in the transperitoneal group: 200 min (35-360) versus 125.6 min (45-180) in the extraperitoneal group (p = .001). The mean number of harvested lymph nodes was higher in the transperitoneal group: 17 (4-37) versus 13 (3-25) in the extraperitoneal group (p = .029). There was no difference in postoperative course and complications between both groups in multivariate analysis. CONCLUSIONS: In nonobese patients, the extraperitoneal PAL is associated with shorter surgical duration, whereas the transperitoneal approach was associated with a higher number of harvested lymph nodes. As a result of improved ergonomy, the transperitoneal approach enables laparoscopic management of operative complications.

Employing laparoscopic surgery for endometriosis.

Endometriosis is a chronic, multifactorial disease, which can impact significantly on a women's quality of life. It is associated with pelvic pain, dyspareunia and intestinal disorders, and can lead to infertility. The use of laparoscopic surgery in the management of endometriosis is well documented; however, the optimal management of women with deep infiltrating disease remains controversial. This review describes the different surgical strategies for the treatment of endometriosis.

Totally laparoscopic intracorporeal anastomosis with natural orifice specimen extraction (NOSE) techniques, particularly suitable for bowel endometriosis.

The objective of this retrospective study was to evaluate the feasibility of natural orifice specimen extraction (NOSE) techniques in 41 patients undergoing bowel resection for treatment of deep infiltrating endometriosis. In all patients laparoscopic treatment of rectovaginal endometriosis with bowel resection had been performed. In 32 patients the classic approach was adopted (group 1), and in 9 a NOSE technique was performed (group 2). Demographic, operative, and postoperative data were compared. Statistical analyses were performed using SPSS software, version 16.0. When needed, qualitative variables were compared using the χ(2) test or the Fisher exact test. Quantitative variables using the t-test were used. The threshold of statistical significance was set at p = .05. No statistically significant difference was observed between the 2 groups. Eight complications (19.5%) were observed, 2 minor (4.8%) and 6 major (14.6%). Of major complications, 2 were observed in the NOSE group (n = 2; 22.2%). It was concluded that the NOSE technique is a feasible approach in patients undergoing bowel resection for treatment of deep infiltrating endometriosis.
