Laparoscopic Radiofrequency Thermal Ablation for Uterine Adenomyosis.

BACKGROUND AND OBJECTIVES: Symptomatic uterine adenomyosis, unresponsive to medical therapy, is a challenging condition for patients who desire to preserve their uterus. This study was an evaluation of the feasibility and efficacy of laparoscopic radiofrequency thermal ablation of symptomatic nodular uterine adenomyosis. METHODS: Fifteen women with symptomatic nodular adenomyosis, who had no plans for pregnancy but declined hysterectomy, underwent radiofrequency thermal ablation. Ultrasonography was performed at baseline and at postoperative follow-ups at 3, 6, 9, and 12 months. The impact of uterine adenomyosis-related symptoms was assessed according to the visual analog scale. RESULTS: The median number of nodular lesions treated per patient was 1 (range, 1-2). The median baseline volume of the adenomyosis area was 60 cm(3) (range, 18-128). The median reduction in volume was 32, 49.4, 59.6, and 65.4% at 3, 6, 9, and 12 months, respectively. A significant progressive improvement in the symptoms score was observed at the 4 follow-ups. CONCLUSION: In this study, laparoscopic radiofrequency thermal ablation reduced uterine adenomyosis-related symptoms and volume, with significant relief of symptoms.

Rare case of giant cystic adenomyoma mimicking a uterine malformation, diagnosed and treated by hysteroscopy.

We describe a case of giant cystic uterine adenomyoma that was diagnosed and treated by hysteroscopy. In a 27-year-old woman with menometrorrhagia, severe dysmenorrhea, and chronic pelvic pain, pelvic ultrasonography revealed an enlarged uterine cavity filled with homogeneous low echogenic fluid content. A large cornual hematometra of 8.0 cm in diameter in a bicornuate uterus was suspected, and this hypothesis was also supported by magnetic resonance imaging findings. On the contrary, hysteroscopy revealed a bilocular huge cystic lesion of the posterior uterine wall that was removed by means of monopolar loop resection. The operative finding and the histopathologic examination confirmed the diagnosis of cystic adenomyoma of the uterus. Hysteroscopy may represent a valid tool for diagnosis and minimally invasive treatment of cystic adenomyoma, including those of large volume. Its use is helpful in differential diagnosis between cystic adenomyoma and uterine malformations as a possible cause of pelvic pain.

Long-term outcome after laparoscopic bowel resections for deep infiltrating endometriosis: a single-center experience after 900 cases.

BACKGROUND: Laparoscopic bowel resections for endometriosis are safe and effective but only short-term follow-up has been evaluated. In the present study long-term outcome in terms of intestinal and urinary function, fertility, chronic pain, and recurrence was assessed. MATERIALS AND METHODS: From January 2002 to December 2010 nine hundred patients underwent laparoscopic bowel resection for endometriosis, and on 774 (86%) a questionnaire was administered. Patients were divided into 3 groups on the strength of the operation date. Postoperative diarrhea, constipation, rectal bleeding, tenesmus, dyschezia, dysuria, dyspareunia, fertility, and recurrence of disease were assessed. RESULTS: The median follow-up was 54 months (range 1-120). All the evaluated symptoms significantly improved over time, with P = 0.0001 for dyspareunia, constipation, and pelvic pain and P = 0.004 for diarrhea. Nonsignificant improvement was reported for dysuria and rectal bleeding (with P = 0.452 and P = 0.097, resp.). CONCLUSIONS: The present results confirm that bowel resections for endometriosis are correlated with an acceptable complication rate even at long-term follow-up and that symptoms significantly improve over time, except for rectal bleeding and dysuria, the latter associated with a neurological damage.

Management of rectosigmoid obstruction due to severe bowel endometriosis.

Bowel obstruction is a rare complication of intestinal endometriosis. The aim of this work was to evaluate outcomes after colorectal resection for bowel obstruction due to endometriosis. Of 720 patients who underwent colorectal resection for bowel endometriosis, 12 (1.7 %) presented with bowel obstruction. Preoperative work-up, management, perioperative and long-term outcomes were analyzed. All lesions were localized in the rectosigmoid tract. All patients underwent colorectal resection, which was carried out laparoscopically in 4 (33 %). Rate of low or ultra-low colorectal anastomoses was 83 %. Four patients (33 %) required blood transfusions. Two patients developed rectovaginal fistulas. After a median follow-up of 38 months, there were no cases of disease recurrence and dyschezia improved in 75 % of patients. Bowel endometriosis should be considered in the differential diagnosis of young women with bowel obstruction. Despite challenging operations, colorectal resections are associated with good outcomes.

Laparoscopic surgical treatment of diaphragmatic endometriosis: a 7-year single-institution retrospective review.

BACKGROUND: Diaphragmatic endometriosis is a rare condition that may cause invalidating epigastric or thoracic pain and catamenial pneumothorax. During the past decades, laparoscopy has been proposed as an optimal tool for diagnosis and surgical eradication of the disease. METHODS: We present a retrospective series of consecutive patients affected by diaphragmatic endometriosis, treated by laparoscopy at our institution, during a period of 7 years. RESULTS: Among 3,008 patients with pelvic endometriosis, 46 cases with intraoperative diagnosis of diaphragmatic endometriosis were identified. Operative findings showed multiple diaphragmatic lesions in 32 (69.5 %) patients and single lesions in 14 (30.4 %). Diaphragmatic implants were distributed on the right side in 40 (86.9 %) patients; in 5 patients (10.8 %) they were bilateral and 1 patient had a single lesion on the left hemidiaphragm. Most of the symptomatic patients were treated by complete excision of the nodules, whereas only three patients referring right upper-quadrant abdominal pain and right shoulder catamenial pain had superficial diaphragmatic endometriosis and were treated by diathermocoagulation. CONCLUSION: Diaphragmatic endometriosis should be included in the concept of complete eradication of endometriosis. This kind of surgery has been shown to be feasible and cost-effective; however, it should be managed in a referral center, by an expert laparoscopic gynecologist with knowledge of oncological surgical techniques, with the support of a general surgeon and a trained anesthesiologist.

Transvaginal sonography for preoperative assessment of deep endometriosis.

PURPOSE: To determinate transvaginal scan (TVS) accuracy in the preoperative evaluation of deep endometriosis in a large cohort of patients with subsequent laparoscopic assessment. METHODS: A retrospective study was performed in a tertiary referral center for endometriosis. Transvaginal scan reports were retrieved from an electronic database of all patients who underwent laparoscopy for pelvic pain or infertility in 2009. The accuracy of TVS was assessed for 10 different sites of pelvic endometriosis. RESULTS: Four hundred twenty women were included in the study. Sensitivity and specificity of TVS were 61% and 99%, respectively, for bladder endometriosis, 52% and 96% for endometriosis of rectovaginal septum, 65% and 99% for rectum endometriosis, and 69% and 98% for endometriosis of the sigmoid colon. CONCLUSIONS: TVS appears to be useful for the detection of endometriosis located in the bladder and involving the sigmoid colon, the rectovaginal septum, and the rectum.

Pericardial, pleural and diaphragmatic endometriosis in association with pelvic peritoneal and bowel endometriosis: a case report and review of the literature.

Diaphragmatic endometriosis is a rare entity, often asymptomatic, which has been described only in small series. It is almost always associated with severe pelvic involvement. The most plausible theory about this condition is based on retrograde menstruation and subsequent transportation of viable cells in peritoneal fluid from the pelvis up the right gutter to the right hemidiaphragm, thus demonstrating its asymmetric distribution on the diaphragm. Pre-operative diagnosis is poorly supported by imaging techniques. In most cases, it is an incidental finding because the lesions may hide behind the right hepatic lobe. In that case it cannot be easily demonstrated with a laparoscope from an umbilical port. Symptomatic diaphragmatic endometriosis is associated with deep lesions which can involve the entire thickness of the diaphragm. In these cases, treatment is more difficult with possible incomplete pain relief and a considerable possibility of recurrence. In this subset, abdominal surgery is recommended. Surgical treatment must be individualized on the basis of the patient's age, fertility desires, type and location of disease and symptoms. We report the surgical treatment of a patient with synchronous pericardial, pleural and diaphragmatic endometriosis associated with pelvic peritoneal and bowel involvement. A review of the literature regarding pericardial and diaphragmatic endometriosis focusing on anatomical and surgical aspects of its management is undertaken.

Vaginal cuff dehiscence in a series of 12,398 hysterectomies: effect of different types of colpotomy and vaginal closure.

OBJECTIVE: To investigate the risk of vaginal cuff dehiscence after different routes of hysterectomy and methods of cuff closure. METHODS: A multi-institutional analysis of 12,398 patients who underwent hysterectomy for both benign and malignant disease between 1994 and 2008 was performed. We analyzed how different routes of hysterectomy and approaches to cuff suture may influence the risk of development of vaginal dehiscence. RESULTS: Women who had total laparoscopic (n=3,573), abdominal (n=4,291), and vaginal (n=4,534) hysterectomies experienced 23 (0.64%), 9 (0.2%), and 6 (0.13%) cases of vaginal cuff dehiscence, respectively. Total laparoscopic hysterectomy was associated with a higher incidence of cuff separations, compared with abdominal hysterectomy (0.64% compared with 0.21%, P=.003) and vaginal hysterectomy (0.64% compared with 0.13%, P<.001). Within the endoscopic group, patients who underwent vaginal closure with laparoscopic knots had a higher rate of cuff dehiscence than patients who had suture with transvaginal knots (20 of 2,332 [0.86%] compared with 3 of 1,241 [0.24%], P=.028). When vaginal suture was performed transvaginally, no statistical difference in vaginal cuff dehiscence rate was observed compared with both abdominal hysterectomy (0.24% compared with 0.21%, P=.83) and vaginal hysterectomy (0.24% compared with 0.13%, P=.38). Use of monopolar energy at the time of colpotomy and reducing the power of monopolar energy from 60 watts to 50 watts when colpotomy was performed at the end of total laparoscopic hysterectomy did not alter the rate of cuff separations. CONCLUSION: Transvaginal suturing appears to reduce the risk of vaginal dehiscence after total laparoscopic hysterectomy.

Nerve-sparing laparoscopic eradication of deep endometriosis with segmental rectal and parametrial resection: the Negrar method. A single-center, prospective, clinical trial.

BACKGROUND: The weight of surgical radicality, together with a lack of anatomical theoretical basis for surgery and inappropriate practical skills, can lead to serious impairments to bladder, rectal, and sexual functions after laparoscopic excision of deep infiltrating endometriosis. Although the "classical" laparoscopic technique for endometriosis excision involving segmental bowel resection has proven to relieve symptoms successfully, it is hampered by several postoperative long-term and/or definitive pelvic dysfunctions. METHODS: In this prospective cohort study, we compare the laparoscopic nerve-sparing approach to the classical laparoscopic procedure in a series of 126 cases. Satisfactory data for bowel, bladder, and sexual function were considered as primary endpoints. RESULTS: A total of 126 patients were considered for analysis: 61 treated with nerve-sparing radical excision of pelvic endometriosis with segmental bowel resection (group B), and 65 treated with the classical technique (group A). Intraoperative, perioperative, and postoperative complications were similar between the two groups. Mean days of self-catheterization were significantly lower in the nerve-sparing group (39.8 days) compared with the non-nerve-sparing group (121.1 days; p < 0.001). The relapse rate within 12 months after surgery was comparable between the two groups. Patients of group A suffered from urinary retention more frequently between 1 and 6 months (p = 0.035) compared with group B and did not experience any improvement between 6 months and 1 year (p = 0.018). Overall detection of severe bladder/rectal/sexual dysfunctions was significantly different between the two groups, and 56 patients of group A (86.2%) reported a significantly higher rate of severe neurologic pelvic dysfunctions vs. 1 patient (1.6%) of group B (p < 0.001). CONCLUSIONS: Our technique appears to be feasible and offers good results in terms of reduced bladder morbidity and apparently higher satisfaction than the classical technique. Considering that this kind of surgery requires uncommon surgical skills and anatomical knowledge, we believe that it should be performed only in selected reference centers.

Laparoscopic rectal resection for severe endometriosis of the mid and low rectum: technique and operative results.

BACKGROUND: Although several studies have shown that laparoscopic resection is safe and feasible in bowel endometriosis, limited data are available on the specific treatment for endometriosis of the rectum. The aim of this study is to describe operative and postoperative outcomes after laparoscopic resection of the mid/low rectum for endometriosis. METHODS: Between 2002 and 2010, 750 patients (median age 33 years) underwent laparoscopic resection of the mid/low rectum for deep infiltrating endometriosis at a single institution. All operations were performed with a standardized technique by a single surgeon. RESULTS: Median operative time was 255 min, and median blood loss 150 ml. Of patients, 7% required blood transfusions. Laparotomic conversion rate was 1.6%. Mechanical low and very low colorectal anastomoses were carried out in 92.5 and 7.5% of patients, respectively. Temporary ileostomy rate was 14.5%. Median length of stay was 8 days. Overall surgical morbidity was 9% with no mortality. Rates of anastomotic leak, rectovaginal fistula, and intraabdominal bleeding were 3, 2, and 1.2%. Forty patients (5.5%) required reoperation. CONCLUSIONS: Laparoscopic resection of the mid/low rectum for endometriosis can be performed safely with acceptable rates of morbidity/reoperation and with low rates of specific complications, including anastomotic leak and rectovaginal fistula. The very high surgical volume of the operating surgeon is probably one of the most important factors in order to maximize postoperative outcomes.

Cyclic sciatica in a patient with deep monolateral endometriosis infiltrating the right sciatic nerve.

STUDY DESIGN: Case report. OBJECTIVE: To show by case presentation, the potential for endometriosis to infiltrate the somatic nerves causing lower extremity neuropathic pain and to discuss possible surgical remedy and the effectiveness of laparoscopic neurolysis. SUMMARY OF BACKGROUND DATA: Pelvic endometriosis may infiltrate the pelvic wall and somatic nerves causing severe neuropathic symptoms. METHODS: We report a case of a 41-year-old woman with a history of severe dysmenorrhea, dyspareunia, and chronic pelvic pain with concomitant monolateral right sciatica because of deep infiltrating pelvic endometriosis involving the sciatic nerve and pelvic wall. RESULTS: The patient was treated by laparoscopic neurolysis of the involved somatic nerves according to the Possover operation. CONCLUSIONS: Endometriosis is a chronic inflammatory disease, potentially infiltrating the somatic nerves. Laparoscopic neurolysis is a therapeutic aetiological therapy, which can relieve neurological symptoms deriving from nerve infiltration/compression.

Vaginal cuff dehiscence after hysterectomy: a multicenter retrospective study.

OBJECTIVE: This study estimates the incidence of vaginal cuff dehiscence resulting from different approaches to hysterectomy. STUDY DESIGN: This multicentric study was carried out retrospectively. We retrospectively analyzed 8635 patients; 37% underwent abdominal hysterectomy, 31.2% vaginal hysterectomy, and 31.8% laparoscopic hysterectomy. All the hysterectomies were considered, vaginal evisceration was registered and analyzed for time of onset, trigger event, presenting symptoms, details of prolapsed organs and type of repair surgery. Continuous variables were compared using the one-way analysis of variance between groups as all data followed a Gaussian distribution, as confirmed by the Kolmogorov-Smirnov test. Differences among subgroups were assessed using the Tukey-Kramer multiple comparisons test. Categorical variables were compared with two tailed Chi-square tests with Yates correction or Fisher's exact test, as appropriate. Pearson's linear correlation was used to verify linear relationships between the dehiscence interval and patient's age at surgery. RESULTS: Thirty-four patients (0.39%) experienced vaginal evisceration. The laparoscopic route was associated with a significantly higher incidence of dehiscence (p<0.05). No differences were found between the 6027 patients (69.8%) who had closure of the vaginal cuff and the 2608 (30.2%) who had an unclosed cuff closure technique. CONCLUSION: Vaginal evisceration after hysterectomy is a rare gynecological surgical complication. Sexual intercourse before the complete healing of the vaginal cuff is the main trigger event in young patients, while evisceration presents as a spontaneous event in elderly patients. Surgical repair can be performed either vaginally or laparoscopically with similar outcomes.

Distribution of endometriotic lesions in endometriosis stage IV supports the menstrual reflux theory and requires specific preoperative assessment and therapy.

A detailed picture of the prevalence and distribution of abdomino-pelvic endometriosis in more that 1,500 cases of endometriosis stage IV is presented. A great prevalence of endometriotic localizations in the posterior pelvic compartment compared to the other quadrants with more frequently observed lesions on the left part of the pelvis supports the menstrual reflux theory. The extent of anatomical sites suggests the opportunity to plan a proper preoperative instrumental study for patients with clinical suspect of severe endometriosis possibly to set a multidisciplinary clinical or surgical management.

Laparoscopic ileocecal resection for bowel endometriosis.

BACKGROUND: Ileocecal endometriosis is a very rare entity, and its diagnosis is usually made during surgery for other endometriosis sites or, rarely, because of direct complications of ileal involvement. This study was designed to analyze perioperative and long-term outcomes after bowel resection for ileocecal endometriosis. METHODS: All patients who underwent surgery for ileocecal endometriosis between October 2004 and January 2008 were prospectively collected and analyzed. RESULTS: Thirty-one women (median age, 34 (range, 25-40) years) were identified. Ileocecal endometriosis was diagnosed during surgery in all patients, and it was associated with colorectal endometriosis in 29 patients (94%). All patients underwent laparoscopic ileocecal resection with no laparotomic conversion. Rectosigmoid or rectal resections was associated in 28 patients (90%) and nodulectomy for sigmoid endometriosis in 1 patient. Median duration of surgery was 301 (range, 90-480) min. Other associated surgical procedures included total hysterectomy (n = 3, 14%), ureterolysis (n = 7, 23%), excision of vesical (n = 4, 13%), vaginal (n = 8, 26%), and parametrial (n = 3, 14%) nodules. There was no mortality. Four patients (13%) required blood transfusions and one a reoperation for bleeding. In a patient who performed ureterolysis, a ureteral fistula occurred. The median hospital stay was 7 (range, 5-18) days. Long-term (>12 months) follow-up data were available for 18 patients. After a median follow-up of 27 months, in 12 of 18 patients (67%) defecation after surgery was normal. Only one patient developed recurrence, which is under medical treatment. CONCLUSIONS: Laparoscopic ileocecal resection is safe and feasible and should be considered as part of surgery for endometriosis with radical intent.

Ureteral endometriosis: clinical and radiological follow-up after laparoscopic ureterocystoneostomy.

BACKGROUND: Ureteral endometriosis is a rare entity that may lead to progressive hydroureteronephrosis and renal loss. When the localization of ureteral stenosis is close to the ureterovesical junction, ureterocystoneostomy may be required. The aim of the present study was to evaluate post-operative complication rates and clinical outcomes at 1- and 6-month follow-up after laparoscopic ureterocystoneostomy. METHOD: Twenty patients who underwent ureterocystoneostomy for pelvic endometriosis in our tertiary referral centre for endoscopic surgery during 1 year were studied. A cystography was performed on Day 7 after surgery to verify the integrity of anastomosis and a satisfactory bladder capacity. Follow-up consisted of gynaecological examination and transvaginal ultrasound at 1 and 6 months after surgery. At 6 months, urography and cystography were also performed. Measurements included results of a pre-operative clinical and instrumental assessment, intra- and post-operative complications, post-operative bladder capacity at cystography and improvement of pain, using a visual analogue scale for the main symptoms related to endometriosis and uro-specific pain. RESULTS: Neither a case of ureteral fistula nor other complications requiring re-intervention were reported. Post-operative transient deficit of bladder voiding occurred in five cases (25%), urinary infection in one and post-operative pyrexia in four (20%) patients. The median time to resuming voiding function was 3 days (range 1-20 days). In six cases, a mild vesico-ureteral reflux at the operated side was observed at 7-day cystography. Post-operative symptomatology was improved significantly (P<0.05) for all symptoms. Urography and cystography performed at 6 months confirmed good post-operative reconstructions in all cases. CONCLUSIONS: The objective of surgical treatment of ureteral endometriosis is to remove the stenotic tract and to preserve renal function. In cases of intrinsic ureteral endometriosis, the procedure of laparoscopic ureterocystoneostomy is feasible and has good outcomes at short- and medium-term follow-up.

Symptomatic vaginal bleeding in a postmenopausal woman revealing colon adenocarcinoma metastasizing exclusively to the vagina.

Vaginal carcinomas are rare entities, accounting for 2% of all malignant cancers of the female genital tract, and the vast majority are metastatic. Adenocarcinoma of the colon metastasizing to the vagina is extremely rare, only 5 cases have been reported. We present the case of a woman who experienced vaginal bleeding as an isolated symptom of vaginal metastasis of colorectal adenocarcinoma. Vaginal localization of metastasis from colorectal cancer significantly worsens the survival prognosis, and a standard treatment has not yet been proposed. Potential mechanisms of spread of colorectal cancer to the vagina and therapeutic approaches are discussed. In this case, treatment included surgery and chemotherapy.
