Deep endometriosis, defined as adenomyosis externa, mostly presents as a single nodule, larger than 1 cm in diameter, in the vesicouterine fold or close to the lower 20 cm of the bowel. When ...diagnosed, most nodules are no longer progressive. In >95% of cases, deep endometriosis is associated with very severe pain (in >95%) and is probably a cofactor in infertility. Its prevalence is estimated to be 1% –2%. Deep endometriosis is suspected clinically and can be confirmed by ultrasonography or magnetic resonance imaging. Contrast enema is useful to evaluate the degree of sigmoid occlusion. Surgery requires expertise to identify smaller nodules in the bowel wall, and difficulty increases with the size of the nodules. Excision is feasible in over 90% of cases often requiring suture of the bowel muscularis or full-thickness defects. Segmental bowel resections are rarely needed except for sigmoid nodules. Deep endometriosis often involves the ureter causing hydronephrosis in some 5% of cases. The latter is associated with 18% ureteral lesions. Deep endometriosis surgery is associated with late complications such as late bowel and ureteral perforations, and recto-vaginal and uretero-vaginal fistulas. Although rare, these complications require expertise in follow-up and laparoscopic management. Pain relief after surgery is excellent and some 50% of women will conceive spontaneously, despite often severe adhesions after surgery. Recurrence of deep endometriosis is rare. In conclusion, defined as adenomyosis externa, deep endometriosis is a rarely a progressive and recurrent disease. The treatment of choice is surgical excision, while bowel resection should be avoided, except for the sigmoid.
As the diagnosis requires a laparoscopy, we only have data in women with pain and/or infertility. Endometriosis has been considered to be a single disease defined as ‘endometrium like glands and ...stroma outside the uterus’. However, subtle, typical, cystic ovarian and deep endometriosis lesions should be considered to be different pathologies which occur in all combinations and with different severities.
All large datasets, especially those based on hospital discharge records, consider endometriosis to be a single disease without taking into account severity. In particular, the variable prevalence and recognition of subtle lesions is problematic. Reliable surgical data are small series not permitting multivariate analysis.
Endometriosis is a hereditary disease. The oxidative stress of heavy menstrual bleeding with retrograde menstruation and an altered pelvic microbiome are probably associated with increasingly severe endometriosis. Whether the prevalence is increasing, or whether endometriosis is associated with fat intake or an increased risk of cardiovascular disease is unclear.
•Endometriosis is defined histologically as glands and stroma outside the uterus.•The diagnosis requires a laparoscopy which is performed in symptomatic women only.•‘Endometriosis’ is a misnomer as it refers to several different diseases.•The G-E theory explains all aspects of endometriosis, including pollution, heredity, and infertility.•There is no evidence that prevalence or severity are increasing or that endometriosis is associated with cardiovascular incidents.
Understanding the pathophysiology of endometriosis is changing our diagnosis and treatment. Endometriosis lesions are clones of specific cells, with variable characteristics as aromatase activity and ...progesterone resistance. Therefore the GE theory postulates GE incidents to start endometriosis, which thus is different from implanted endometrium. The subsequent growth in the specific environment of the peritoneal cavity is associated with angiogenesis, inflammation, immunologic changes and bleeding in the lesions causing fibrosis. Fibrosis will stop the growth and lesions look burnt out. The pain caused by endometriosis lesions is variable: some lesions are not painful while other lesions cause neuroinflammation at distance up to 28 mm. Diagnosis of endometriosis is made by laparoscopy, following an experience guided clinical decision, based on history, symptoms, clinical exam and imaging. Biochemical markers are not useful. For deep endometriosis, imaging is important before surgery, notwithstanding rather poor predictive values when confidence limits, the prevalence of the disease and the absence of stratification of lesions by size, localization and depth of infiltration, are considered. Surgery of endometriosis is based on recognition and excision. Since the surrounding fibrosis belongs to the body with limited infiltration by endometriosis, a rim of fibrosis can be left without safety margins. For deep endometriosis, this results in a conservative excision eventually with discoid excision or short bowel resections. For cystic ovarian endometriosis superficial destruction, if complete, should be sufficient. Understanding pathophysiology is important for the discussion of early intervention during adolescence. Considering neuroinflammation at distance, the indication to explore large somatic nerves should be reconsidered. Also, medical therapy of endometriosis has to be reconsidered since the variability of lesions results in a variable response, some lesions not requiring estrogens for growth and some being progesterone resistant. If the onset of endometriosis is driven by oxidative stress from retrograde menstruation and the peritoneal microbiome, medical therapy could prevent new lesions and becomes indicated after surgery.
Laparoscopic mesh sacropexy (LS) or transvaginal mesh repair (TVM) are surgical techniques used to treat cystoceles. Health authorities have highlighted the need for comparative studies to evaluate ...the safety of surgeries with meshes.
To compare the rate of complications, and functional and anatomical outcomes between LS and TVM.
Multicenter randomized controlled trial from October 2012 to April 2014 in 11 French public hospitals. Women with cystocele stage ≥2 (pelvic organ prolapse quantification), aged 45–75 yr, without previous prolapse surgery.
Synthetic nonabsorbable mesh placed in the vesicovaginal space, sutured to the promontory (LS) or maintained by arms through pelvic ligaments (TVM).
Rate of surgical complications ≥grade II according to the modified Clavien–Dindo classification at 1 yr. Secondary outcomes were reintervention rate, and functional and anatomical results.
A total of 130 women were randomized in LS and 132 in TVM; five women withdrew before intervention, leaving 129 in LS and 128 in TVM. The rate of complications ≥grade II was lower after LS than after TVM, but did not meet statistical significance (17% vs 26%, treatment difference 8.6% 95% confidence interval, CI −1.5 to 18; p=0.088). The rate of complications of grade III or higher was nonetheless significantly lower after LS (LS=0.8%, TVM=9.4%, treatment difference 8.6% 95% CI 3.4%; 15%; p=0.001). LS was converted to TVM in 6.3%. The total reoperation rate was lower after LS but did not meet statistical significance (LS=4.7%, TVM=10.9%, treatment difference 6.3% 95% CI −0.4 to 13.3; p=0.060). There was no difference in symptoms, quality of life, improvement, composite definition of success, anatomical results rates between groups except for the vaginal apex and length, and dyspareunia (in favor of LS).
LS is a valuable option for primary repair of cystocele in sexually active patients. LS is safer than TVM, but may not be feasible in all cases. Both techniques offer same functional outcomes, success rates, and anatomical outcomes, but sexual function is better preserved by LS.
Our study demonstrates that laparoscopic sacropexy (LS) is a valuable option for primary repair of cystocele. LS offers equivalent success rates to vaginal mesh procedures, but is safer with a lower rate of complications and reoperations, and sexual function is better preserved.

Objective To report on the prevalence, surgical management, and outcome of urinary tract endometriosis (UTE) in a cohort of 221 patients undergoing laparoscopic surgery for severe endometriosis. UTE ...can cause significant morbidity, such as silent kidney or progressive renal function loss. Its frequency is underestimated and data on laparoscopic management are scarce. Methods Between 2007 and 2010, 43 patients were eligible for this single-center, retrospective study. The inclusion criterion was the presence of UTE (ie, bladder and/or ureteral endometriosis). All patients were operated laparoscopically. Results The prevalence of UTE was 19.5% (43/221). There was no correlation between bladder and ureteral endometriosis ( P >.05). Ureteral endometriosis was associated with patient's age ( P <.01). Patients with bladder, but not ureteral, involvement complained more frequently about dysuria, hematuria, and urinary tract infections. Intraoperative and magnetic resonance imaging (MRI) findings revealed a moderate to good correlation. UTE was not associated with rectovaginal or bowel endometriosis, but rather with involvement of the uterosacral ligaments ( P <.01). Twenty-two patients with bladder endometriosis were treated by mucosal skinning and 11 patients underwent partial cystectomy. Superficial ureteral excision was performed in 4 patients, whereas resection with ureteroureterostomy was done in 9 patients. There was no difference regarding the intra- and postoperative complications in patients with or without UTE. Conclusion In severe pelvic endometriosis, involvement of the urinary tract is quite common. Laparoscopic management is feasible and safe. Because of the lack of specific symptoms, the preoperative diagnosis of ureteral endometriosis still remains a challenge. Pelvic MRI represents a useful preoperative diagnostic tool.
To evaluate the impact of laparoscopic excision of lesions on deep endometriosis-related infertility.
Retrospective study.
Endometriosis tertiary referral center (Canadian Task Force II-2).
A group ...of 115 patients who had undergone laparoscopic surgery for infertility with histologic confirmation of deep endometriosis.
Patient medical records and operative reports were reviewed. Telephone interviews were conducted for long-term follow-up of fertility outcomes.
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).
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.
For 100 years, pelvic endometriosis has been considered to originate from the implantation of endometrial cells following retrograde menstruation or metaplasia. Since some observations, such as the ...clonal aspect, the biochemical variability of lesions and endometriosis in women without endometrium, the genetic-epigenetic (G-E) theory describes that endometriosis only begins after a series of cumulative G-E cellular changes. This explains that the endometriotic may originate from any pluripotent cell apart from the endometrium, that 'endometrium-like cells' can harbour important G-E differences, and that the risk is higher in predisposed women with more inherited incidents. A consequence is a high risk after puberty which decreases progressively thereafter. Considering a 10-year delay between initiation and performing a laparoscopy, this was observed in the United Arab Emirates, Belgium, France and USA. The subsequent growth varies with the G-E changes and the environment but is self-limiting probably because of the immunologic reaction and fibrosis. That each lesion has a different set of G-E incidents explains the variability of pain and the response to hormonal treatment. New lesions may develop, but recurrences after surgical excision are rare. The fibrosis around endometriosis belongs to the body and does not need to be removed. This suggests conservative excision or minimal bowel without safety margins and superficial treatment of ovarian endometriosis. This G-E concept also suggests prevention by decreasing oxidative stress from retrograde menstruation or the peritoneal microbiome. This suggests the prevention of vaginal infections and changes in the gastrointestinal microbiota through food intake and exercise. In conclusion, a higher risk of initiating endometriosis during adolescence was observed in UAE, France, Belgium and USA. This new understanding and the limited growth opens perspectives for earlier diagnosis and better treatment.
Menstruation is a developmental milestone and usually marks healthy and normal pubertal changes in females. Menarche refers to the onset of first menstruation in a female. The causes of primary ...amenorrhea include outflow tract abnormalities, resistant endometrium, primary ovarian insufficiency, and disorders of the hypothalamus, pituitary, or other endocrine glands. A rare variant of mullerian agenesis, which warrants an individualized approach to management, is presented here.
We present here the case of a 25-year-old Indian female with pain in the lower abdomen and primary amenorrhea. After a thorough history, clinical examination, imaging, and diagnostic laparoscopy, two small uteri, a blind upper half vagina, bilateral polycystic ovaries, and a blind transverse connection between the two uteri-a horseshoe band cervix-were detected, which confirmed the diagnosis of mullerian agenesis. There was evidence of adenomyosis in the mullerian duct element. This is a rare form of Müllerian abnormality with an unusual presentation.
Mullerian agenesis is the most common cause of primary amenorrhea with well-developed secondary sexual characteristics. There are various forms of mullerian agenesis. Most of the cases are managed by a multidisciplinary team. Rare variants warrant an individualized approach to management.
Surgical knots are sequences of half-knots (H) or half-hitches (S), defined by their number of throws, by an opposite or similar rotation compared with the previous one, and for half-hitches whether ...they are sliding (s) or blocking (b). Opposite rotation results in (more secure) symmetric (s) knots, similar rotation in asymmetric (a) knots, and changing the active and passive ends has the same effect as changing the rotation. Loop security is the force to keep tissue together after a first half-knot or sliding half-hitches. With polyfilament sutures, H2, H3, SSs, and SSsSsSs have a loop security of 10, 18, 28, and 48 Newton (N), respectively. With monofilament sutures, they are only 7, 16, 18, and 25 N. Since many knots can reorganize, the definition of knot security as the force at which the knot opens or the suture breaks should be replaced by the clinically more relevant percentage of clinically dangerous and insecure knots. Secure knots with polyfilament sutures require a minimum of four or five throws, but the risk of destabilization is high. With monofilament sutures, only two symmetric+4 asymmetric blocking half-hitches are secure. In conclusion, in gynecology and in open and laparoscopic surgery, half-hitch sequences are recommended because they are mandatory for monofilament sutures, adding flexibility for loop security with less risk of destabilization.
To report the clinical presentation and long-term issues of adolescent endometriosis.
Retrospective cohort study.
Single private clinical center, Bordeaux, France.
Adolescents with a confirmed ...diagnosis of endometriosis.
Surgical excision or ablation or lesions performed at laparoscopy.
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%).
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.
