Associated ileocaecal location is a marker for greater severity of low rectal endometriosis.

OBJECTIVE: To determine whether ileocaecal endometriosis (ICE) is a marker for low rectal endometriosis (LRE) severity. DESIGN: Retrospective cohort study. SETTING: France. POPULATION AND SAMPLE: Analysis of 375 colorectal resections performed in women undergoing complete surgery for LRE from January 1995 to December 2015 in a university centre for endometriosis. METHODS: Univariate and multivariate analysis of anatomical, postoperative clinical, and long-term outcomes according to presence of ICE. MAIN OUTCOMES AND MEASURES: Mean number and type of deep infiltrating endometriosis (DIE) lesions, the existence of an associated endometrioma, and mean total American Society for Reproductive Medicine (ASRM) score. RESULTS: The prevalence of ICE was 25.6%. Primary end-point data showed that women with ICE had a significantly higher adjusted number of DIE lesions (OR = 1.43, 95% CI 1.02-3.03; P = 0.048), higher prevalence of endometriomas (OR = 1.91, 95% CI 1.04-3.51; P = 0.044), more associated DIE sigmoid lesions (OR = 2.12, 95% CI 1.07-3.91; P = 0.025), and a higher mean total ASRM score (OR = 2.07, 95% CI 1.12-4.14; P = 0.025). Women with ICE resected during the surgical procedure for LRE did not have more adverse postoperative clinical outcomes than ICE-negative patients. CONCLUSION: Ileocaecal endometriosis was significantly associated with greater LRE severity. In a complete surgical resection strategy, combining resection of ICE and LRE did not appear to increase postoperative rates of complications, morbidity or recurrence, nor did it seem to impair long-term clinical outcomes. TWEETABLE ABSTRACT: In women with low rectal endometriosis, 25% have an associated ileocaecal location that is a marker for severity.

A post-market, prospective, multi-center, single-arm clinical investigation of Phasix™ mesh for VHWG grade 3 midline incisional hernia repair: a research protocol.

BACKGROUND: Incisional heia is a frequent complication of midline laparotomy. The use of mesh in hernia repair has been reported to lead to fewer recurrences compared to primary repair. However, in Ventral Hernia Working Group (VHWG) Grade 3 hernia patients, whose hernia is potentially contaminated, synthetic mesh is prone to infection. There is a strong preference for resorbable biological mesh in contaminated fields, since it is more able to resist infection, and because it is fully resorbed, the chance of a foreign body reaction is reduced. However, when not crosslinked, biological resorbable mesh products tend to degrade too quickly to facilitate native cellular ingrowth. Phasix™ Mesh is a biosynthetic mesh with both the biocompatibility and resorbability of a biological mesh and the mechanical strength of a synthetic mesh. This multi-center single-arm study aims to collect data on safety and performance of Phasix™ Mesh in Grade 3 hernia patients. METHODS: A total of 85 VHWG Grade 3 hernia patients will be treated with Phasix™ Mesh in 15 sites across Europe. The primary outcome is Surgical Site Occurrence (SSO) including hematoma, seroma, infection, dehiscence and fistula formation (requiring intervention) through 3 months. Secondary outcomes include recurrence, infection and quality of life related outcomes after 24 months. Follow-up visits will be at drain removal (if drains were not placed, then on discharge or staple removal instead) and in the 1st, 3rd, 6th, 12th, 18th and 24th month after surgery. CONCLUSION: Based on evidence from this clinical study Depending on the results this clinical study will yield, Phasix™ Mesh may become a preferred treatment option in VHWG Grade 3 patients. TRIAL REGISTRATION: The trial was registered on March 25, 2016 on clinicaltrials.gov: NCT02720042 .

Preoperative imaging and prediction of oesophageal conduit necrosis after oesophagectomy for cancer.

BACKGROUND: Oesophageal conduit necrosis following oesophagectomy is a rare but life-threatening complication. The present study aimed to assess the impact of coeliac axis stenosis on outcomes after oesophagectomy for cancer. METHODS: The study included consecutive patients who had an Ivor Lewis procedure with curative intent for middle- and lower-third oesophageal cancer at two tertiary referral centres. All patients underwent preoperative multidetector CT with arterial phase to detect coeliac axis stenosis. The coeliac artery was classified as normal, with extrinsic stenosis due to a median arcuate ligament or with intrinsic stenosis caused by atherosclerosis. RESULTS: Some 481 patients underwent an Ivor Lewis procedure. Of these, ten (2·1 per cent) developed oesophageal conduit necrosis after surgery. Coeliac artery evaluation revealed a completely normal artery in 431 patients (91·5 per cent) in the group without conduit necrosis and in one (10 per cent) with necrosis (P < 0·001). Extrinsic stenosis of the coeliac artery due to a median arcuate ligament was found in two patients (0·4 per cent) without conduit necrosis and five (50 per cent) with necrosis (P < 0·001). Intrinsic stenosis of the coeliac artery was found in 11 (2·3 per cent) and eight (80 per cent) patients respectively (P < 0·001). Eight patients without (1·7 per cent) and five (50 per cent) with conduit necrosis had a single and thin left gastric artery (P < 0·001). CONCLUSION: This study suggests that oesophageal conduit necrosis after oesophagectomy for cancer may be due to pre-existing coeliac axis stenosis.

Fusion imaging for evaluation of deep infiltrating endometriosis: feasibility and preliminary results.

OBJECTIVE: Magnetic resonance imaging (MRI) and ultrasound scanning complement each other in screening for and diagnosis of endometriosis. Fusion imaging, also known as real-time virtual sonography, is a new technique that uses magnetic navigation and computer software for the synchronized display of real-time ultrasound and multiplanar reconstructed MR images. Our aim was to evaluate the feasibility and ability of fusion imaging to assess the main anatomical sites of deep infiltrating endometriosis (DIE) in patients with suspected active endometriosis. METHODS: This prospective study was conducted over a 1-month period in patients referred to a trained radiologist for an ultrasound-based evaluation for endometriosis. Patients with a prior pelvic MRI examination within the past year were offered fusion imaging, in addition to the standard evaluation. All MRI examinations were performed on a 1.5-T MRI machine equipped with a body phased-array coil. The MRI protocol included acquisition of at least two fast spin-echo T2-weighted orthogonal planes. The Digital Imaging Communications in Medicine dataset acquired at the time of the MRI examination was loaded into the fusion system and displayed together with the ultrasound image on the same monitor. The sets of images were then synchronized manually using one plane and one anatomical reference point. The ability of this combined image to identify and assess the main anatomical sites of pelvic endometriosis (uterosacral ligaments, posterior vaginal fornix, rectum, ureters and bladder) was evaluated and compared with that of standard B-mode ultrasound and MRI. RESULTS: Over the study period, 100 patients were referred for ultrasound examination because of endometriosis. Among them were 20 patients (median age, 35 (range, 27-49) years) who had undergone MRI examination within the past year, with a median (range) time interval between MRI and ultrasound examination of 171 (1-350) days. All 20 patients consented to undergo additional evaluation by fusion imaging. However, in three (15%) cases, fusion imaging was not technically possible because of changes since the initial MRI examination resulting from either interval surgery (n = 2; 10%) or pregnancy (n = 1; 5%). Data acquisition, matching and fusion imaging were performed in under 10 min in each of the other 17 cases. The overall ability of each technique to identify and assess the main anatomical landmarks of endometriosis was as follows: uterosacral ligaments: ultrasound, 88% (30/34); MRI, 100% (34/34); fusion imaging, 100% (34/34); posterior vaginal fornix: ultrasound, 88% (30/34); MRI, 100% (34/34); fusion imaging, 100% (34/34); rectum: ultrasound, 100% (17/17); MRI, 82.3% (14/17); fusion imaging, 100% (17/17); ureters: ultrasound, 0%; MRI, 100% (34/34); fusion imaging, 100% (34/34); and bladder: ultrasound, 100%; MRI, 100%; fusion imaging, 100%. CONCLUSION: Fusion imaging is feasible for the assessment of endometriotic lesions. Because it combines information from both ultrasound and MRI techniques, fusion imaging allows better identification of the main anatomical sites of DIE and has the potential to improve the performance of ultrasound and MRI examination.

AXIN genetic analysis in adrenocortical carcinomas updated.

BACKGROUND: Wnt/ß-catenin signaling pathway activation plays an important role in adrenocortical tumorigenesis, but is only in part related to ß-catenin activating somatic mutations. Recently, genetic alteration in AXIN2, a key component of the Wnt/ß-catenin signaling pathway, has been described in adrenocortical tumors and specifically in adrenocortical carcinoma (ACC). AIM: To assess frequency and consequences of AXIN genes alteration on a large cohort of ACC. PATIENTS AND METHODS: Forty-nine adult sporadic ACC, with expression data available, in addition to both ACC cell lines H295 and H295R were studied. AXIN2 exon 8 hot-spot sequencing was performed on the entire cohort. AXIN1 entire coding region was studied on the 8 ACC with nuclear ß-catenin staining. RESULTS: The previously described AXIN2 in-frame heterozygous 12bp deletion c2013_2024del12 was found in 1 of the 49 ACC studied (2%), in a tumor with pSer45del activating CTNNB1 mutation and nuclear ß-catenin staining. This heterozygous deletion was also found in the patient's germline DNA, extracted from peripheral blood leukocytes. This genetic alteration was also present in H295 and H295R cell lines. The single-nucleotide polymorphism rs35415678 was found with an allele frequency similar to those found in reference populations. No correlation between AXIN2 expression, AXIN2 genetic variant or nuclear ß- catenin staining was observed. No AXIN1 alterations were found in the 8 ACC studied. CONCLUSIONS: AXIN genes do not play a major role in ACC tumorigenesis and Wnt/ß-catenin signaling pathway activation. AXIN2 germline variant c2013_2024del12 is likely to be a non-pathogenic polymorphism.

Five-Year Follow-Up of a Slowly Resorbable Biosynthetic P4HB Mesh (Phasix) in VHWG Grade 3 Incisional Hernia Repair.

Objective: To assess the 5-year recurrence rate of incisional hernia repair in Ventral Hernia Working Group (VHWG) 3 hernia with a slowly resorbable mesh. Summary Background Data: Incisional hernia recurs frequently after initial repair. In potentially contaminated hernia, recurrences rise to 40%. Recently, the biosynthetic Phasix mesh has been developed that is resorbed in 12-18 months. Resorbable meshes might be a solution for incisional hernia repair to decrease short- and long-term (mesh) complications. However, long-term outcomes after resorption are scarce. Methods: Patients with VHWG grade 3 incisional midline hernia, who participated in the Phasix trial (Clinilcaltrials.gov: NCT02720042) were included by means of physical examination and computed tomography (CT). Primary outcome was hernia recurrence; secondary outcomes comprised of long-term mesh complications, reoperations, and abdominal wall pain [visual analogue score (VAS): 0-10]. Results: In total, 61/84 (72.6%) patients were seen. Median follow-up time was 60.0 [interquartile range (IQR): 55-64] months. CT scan was made in 39 patients (68.4%). A recurrence rate of 15.9% (95% confidence interval: 6.9-24.8) was calculated after 5 years. Four new recurrences (6.6%) were found between 2 and 5 years. Two were asymptomatic. In total, 13/84 recurrences were found. No long-term mesh complications and/or interventions occurred. VAS scores were 0 (IQR: 0-2). Conclusions: Hernia repair with Phasix mesh in high-risk patients (VHWG 3, body mass index >28) demonstrated a recurrence rate of 15.9%, low pain scores, no mesh-related complications or reoperations for chronic pain between the 2- and 5-year follow-up. Four new recurrences occurred, 2 were asymptomatic. The poly-4-hydroxybutyrate mesh is a safe mesh for hernia repair in VHWG 3 patients, which avoids long-term mesh complications like pain and mesh infection.

Slowly resorbable biosynthetic mesh: 2-year results in VHWG grade 3 hernia repair.

INTRODUCTION: Information on the long-term performance of biosynthetic meshes is scarce. This study analyses the performance of biosynthetic mesh (Phasix™) over 24 months. METHODS: A prospective, international European multi-center trial is described. Adult patients with a Ventral Hernia Working Group (VHWG) grade 3 incisional hernia larger than 10 cm2, scheduled for elective repair, were included. Biosynthetic mesh was placed in sublay position. Short-term outcomes included 3-month surgical site occurrences (SSO), and long-term outcomes comprised hernia recurrence, reoperation, and quality of life assessments until 24 months. RESULTS: Eighty-four patients were treated with biosynthetic mesh. Twenty-two patients (26.2%) developed 34 SSOs, of which 32 occurred within 3 months (primary endpoint). Eight patients (11.0%) developed a hernia recurrence. In 13 patients (15.5%), 14 reoperations took place, of which 6 were performed for hernia recurrence (42.9%), 3 for mesh infection (21.4%), and in 7 of which the mesh was explanted (50%). Compared to baseline, quality of life outcomes showed no significant difference after 24 months. Despite theoretical resorption, 10.7% of patients reported presence of mesh sensation in daily life 24 months after surgery. CONCLUSION: After 2 years of follow-up, hernia repair with biosynthetic mesh shows manageable SSO rates and favorable recurrence rates in VHWG grade 3 patients. No statistically significant improvement in quality of life or reduction of pain was observed. Few patients report lasting presence of mesh sensation. Results of biosynthetic mesh after longer periods of follow-up on recurrences and remodeling will provide further valuable information to make clear recommendations.

Risk factors for conversion and complications after unilateral laparoscopic adrenalectomy.

BACKGROUND: Laparoscopic adrenalectomy (LA) is the procedure of choice for surgical management of most benign adrenal tumours, with a reported overall complication rate around 10 per cent. The aim of this study was to determine predictive factors for postoperative complications and conversion to open surgery after unilateral LA. METHODS: From 1994 to 2009, consecutive patients undergoing unilateral LA by the lateral transabdominal approach were analysed from a prospectively maintained database. A mass larger than 12 cm in diameter and suspected primary adrenal carcinoma were considered contraindications to LA. Predictive factors for postoperative complications and conversion to open surgery were analysed. RESULTS: Some 462 patients were analysed. There were no postoperative deaths. Postoperative complications occurred in 53 patients (11·5 per cent), medical complications in 28, and surgical complications in 33 patients. Six patients underwent reoperation for complications. Multivariable logistic regression analysis showed that conversion to open surgery (odds ratio (OR) 6·20, 95 per cent confidence interval 2·08 to 18·53; P = 0·001) and left-sided tumour (OR 1·89, 1·02 to 3·52; P = 0·044) were independent predictive factors for overall complications. Conversion to open surgery was the only independent predictive factor for medical complications (OR 12·88, 4·21 to 39·41; P = 0·001), and left-sided LA was the only predictive factor for surgical complications (OR 2·22, 1·01 to 4·89; P = 0·047). No factor was predictive of conversion to open surgery. CONCLUSION: In this single-institution study, conversion to open surgery and left-sided tumours were independent predictive factors for overall complications, but none of the variables analysed was predictive of conversion.

[Recurrent carcinoid tumor and 18F-DOPA PET]. / Récidive d'une tumeur carcinoïde et TEP à la (18)F-DOPA.

We report the case of a carcinoid tumor with suspicion of recurrence on biology. Scintigraphic explorations of the whole body had a major role in diagnostic of this recurrence. OctreoScan((R)) showed an abdominal uptake corresponding to a mesenteric lymph node. PET with (18)F-DOPA also showed a liver uptake corresponding to liver metastases.

Assessment of determinants for osteoporosis in elderly men.

SUMMARY: The aim of this cross-sectional study was to determine and quantify some determinants associated to low bone mineral density (BMD) in elderly men. This study showed that ageing, a lower body mass index (BMI), a higher blood level of C-terminal cross-linking telopeptides of type I collagen (CTX-1), family history of osteoporosis, and/or fracture and prior fracture were associated with bone mineral density. INTRODUCTION: Our aims were to identify some determinants associated to low bone mineral density in men and to develop a simple algorithm to predict osteoporosis. METHODS: A sample of 1,004 men aged 60 years and older was recruited. Biometrical, serological, clinical, and lifestyle determinants were collected. Univariate, multivariate, and logistic regression analyses were performed. Receiver operating characteristic analysis was used to assess the discriminant performance of the algorithm. RESULTS: In the multiple regression analysis, only age, BMI, CTX-1, and family history of osteoporosis and/or fracture were able to predict the femoral neck T-score. When running the procedure with the total hip T-score, prior fracture also appeared to be significant. With the lumbar spine T-score, only age, BMI, and CTX-1 were retained. The best algorithm was based on age, BMI, family history, and CTX-1. A cut-off point of 0.25 yielded a sensibility of 78%, a specificity of 59% with an area under the curve of 0.73 in the development and validation cohorts. CONCLUSION: Ageing, a lower BMI, higher CTX-1, family history, and prior fracture were associated with T-score. Our algorithm is a simple approach to identify men at risk for osteoporosis.

Increased arterial pressure is not predictive of haemodynamic instability in patients undergoing adrenalectomy for phaeochromocytoma.

BACKGROUND: Pre-operative hypotensive drugs are assumed to have dramatically decreased operative mortality and morbidity in patients undergoing phaeochromocytoma removal only in non-controlled studies. We evaluated the predictive value of pre-operative high systolic arterial pressure (SAP) on intra- and post-operative haemodynamic instability, in 96 patients undergoing laparoscopic adrenalectomy for phaeochromocytoma. METHODS: Ninety-six consecutive patients underwent laparoscopic adrenalectomy for phaeochromocytoma. Pre-operative SAP was not systematically normalised, provided that increased SAP was clinically tolerated. Intravenous nicardipine, esmolol and norepinephrine were intraoperatively titrated to treat SAP increase >150 mmHg, tachycardia >90-110/min, arrhythmia or SAP decrease under 90 mmHg, respectively. Volume expanders were not systematically administered. Patients with increased and normal pre-operative SAP were compared with respect to (a) nicardipine, esmolol and norepinephrine requirement, (b) highest intraoperative SAP and heat rate, (c) lowest intraoperative SAP, (d) duration of surgery and (e) norepinephrine requirement following tumour removal. RESULTS: Groups did not differ significantly with respect to data defined as being indicative of perioperative haemodynamic instability (all P values>0.05). DISCUSSION: As previously demonstrated, in patients undergoing phaeochromocytoma removal, perioperative haemodynamic changes are mainly due to catecholamine release during tumour manipulation, and to the decrease in catecholamine level following tumour removal. Whether pre-operative hypotensive drugs are likely to alter these changes remains questionable. CONCLUSION: For most patients scheduled for laparoscopic phaeochromocytoma removal, surgery can be carried out without systematic pre-operative arterial pressure normalisation.

Operative risks of digestive surgery in cirrhotic patients.

Digestive surgery in cirrhotic patients has long been limited to the treatment of disorders related to the liver disease (portal hypertension, hepatocellular carcinoma and umbilical hernia). The improvement in cirrhotic patient management has allowed an increase in surgical procedures for extrahepatic indications. The aim of this study was to evaluate the operative risks of such surgical procedures. Extrahepatic surgery in cirrhotic patients is associated with high mortality and morbidity. Emergency surgery, gastrointestinal tract opening (esophagus, stomach and colon), <30 g/L serum albumin, transaminase levels more than three times the upper limit of normal, ascites, and intraoperative transfusions are the main risk factors for postoperative death. In Child A patients, the operative risk of elective surgery is moderate and surgical indications are not altered by the presence of cirrhosis. The laparoscopic approach should be recommended because of the potentially lower morbidity. In Child C patients, operative mortality is often higher than 40%; surgical indications must remain exceptional and non operative management has to be preferred. In Child B patients, preoperative improvement of liver function is mandatory for lower risk surgery.

Randomized clinical trial of early versus delayed temporary stoma closure after proctectomy.

BACKGROUND: Temporary faecal diversion is recommended with a low colorectal, coloanal or ileoanal anastomosis (LA). This randomized study evaluated early (EC; 8 days) versus late (LC; 2 months) closure of the temporary stoma. METHODS: Patients undergoing rectal resection with LA were eligible to participate. If there was no radiological sign of anastomotic leakage after 7 days, patients were randomized to EC or LC. The primary endpoints were postoperative morbidity and mortality 90 days after the initial resection. RESULTS: Some 186 patients were analysed. There were no deaths within 90 days and overall morbidity rates were similar in the EC and LC groups (31 versus 38 per cent respectively; P = 0.254). Overall surgical complication (both 15 per cent; P = 1.000) and reoperation (both 8 per cent; P = 1.000) rates were similar, but wound complications were more frequent after EC (19 versus 5 per cent; P = 0.007). Small bowel obstruction (3 versus 16 per cent; P = 0.002) and medical complications (5 versus 15 per cent; P = 0.021) were more common with LC. Median (range) hospital stay was reduced by EC (16 (6-59) versus 18 (9-262) days; P = 0.013). CONCLUSION: Early stoma closure is feasible in selected patients, with reduced hospital stay, bowel obstruction and medical complications, but a higher wound complication rate. REGISTRATION NUMBER: NCT00428636 (http://www.clinicaltrials.gov).

Median arcuate ligament in orthotopic liver transplantation: relevance to arterial reconstruction.

Median arcuate ligament (MAL) syndrome results from luminal narrowing of the celiac artery by the insertion of the diaphragmatic muscle fibers or by fibrous bands of the celiac nervous plexus. In 10% to 50% of cases it is responsible for significant angiographic celiac trunk compression. In orthotopic liver transplantation (OLT), the presence of celiac compression by MAL is considered to be a risk factor for hepatic arterial thrombosis (HAT); it may lead to graft loss. Various surgical procedures have been proposed to overcome the impact of MAL in OLT, but their impact is still ill defined. The aim of our study was to compare standard hepatic artery reconstruction and graft reconstruction (aortohepatic bypass) in terms of HAT among patients with MAL undergoing OLT. We retrospectively reviewed 168 adult recipients of OLT performed from January 1991 to December 1998. Ten cases (5.6%) of celiac compression by MAL were identified after celiomesenteric arteriography. There was no significant difference in terms of HAT incidence when aortohepatic bypass was performed compared to a standard anastomosis; moreover, this was greater in the graft reconstruction group (25% vs 17%; P = .67). In our opinion, the presence of an arcuate ligament should not contraindicate a routine hepatic artery reconstruction.

Massive postoperative ascites following pancreatic cysts fenestration in a patient with von Hippel-Lindau disease.

Pancreatic lesions in von Hippel Lindau disease (VHLD) are frequent and mainly consist of cystic lesions, which should not be resected because of their benign evolution. Solid lesions, mostly pancreatic endocrine tumors (PET), are rare and usually occur in combination with cystic lesions. We report a case of a patient with VHLD who underwent PET enucleation in a polycystic pancreas requiring fenestration of multiple adjacent cysts, to ensure complete resection with free resection margins. The postoperative course was complicated by massive ascitic fluid effusion, probably related to pancreatic-cyst fenestration. Although this complication is well-known after liver-cyst fenestration, it has not been reported after pancreatic-cyst fenestration. This observation emphasizes that morbidity from surrounding pancreatic polycystic disease should not be underestimated in pancreatic surgery for VHLD.

[Surgical management of primary esophageal motility disorders]. / Traitement chirurgical des troubles moteurs de l'oesophage.

Primary esophageal motility disorders are rare, the most common diagnoses being achalasia and diffuse esophageal spasm. Treatment aims to alleviate symptoms and may be medical, endoscopic, or surgical. Achalasia is most commonly treated by pneumatic dilatation or by laparoscopic Heller cardiomyotomy. Pneumatic dilatation is effective in 60-80% of cases, but functional results deteriorate over time. Surgical treatment is indicated when endoscopic dilatation is contraindicated or has failed. Functional results after cardiomyotomy are satisfactory in 90% of cases and results appear to be stable over time. The need for an associated antireflux procedure and the type of fundoplication remain controversial. For diffuse esophageal spasm, extended esophageal myotomy has yielded satisfactory functional results, but surgical treatment should be reserved for selected patients with severe symptoms.

Polyester mosquito net mesh for inguinal hernia repair: A feasible option in resource limited settings in Cameroon?

BACKGROUND: In developing countries, most inguinal hernia repairs are performed using Bassini or Shouldice techniques resulting in higher recurrence rates than with mesh placement. Our study aimed to evaluate the postoperative course and quality of life of patients undergoing inguinal hernia repair with a polyester mosquito net meshes during non-governmental organization health campaigns in Cameroon. METHODS: Patients were prospectively included from January to November 2013. Meshes were made from a polyester non-impregnated mosquito net purchased at a local market in Yaounde and sterilized on site. RESULTS: The total cost of a mesh was 0.21 USD. Among the 41 patients included in the study, 33 (80.5%) were men, 30 (72%) were farmers and the median age was 52 (21-80) years. The time between the onset of symptoms and surgery was 24 (3-240) months. Eleven (26.8%) patients had a previous history of hernia repair: 4 (9.7%) had been operated on the contralateral side and 7 (17.1%) had a recurrence. No intraoperative event related to the meshes was recorded. Three patients (7.2%) had a postoperative uninfected scrotal seroma, and 1 patient (2.4%) experienced a superficial skin infection that was treated using local care and oral antibiotics. No allergic rejection or deep infection was observed. CONCLUSIONS: Meshes made from sterilized mosquito nets are safe and effective and provide a cost-effective alternative to commercially available meshes in countries with limited resources especially during non-governmental organization health campaigns.

[Surgical treatment of rectal endometriosis]. / Traitement chirurgical de l'endométriose rectale.

Intestinal endometriosis accounts for 8-12% of all endometriosis and rectal involvement is most often encountered in the context of deep pelvic infiltration. Intestinal symptoms, often nonspecific, are most typically seen as painful defecation or constipation worsening in the premenstrual period associated with pelvic pain, dysmenorrheal, dyspareunia, and infertility. Physical examination should include a pelvic exam under anesthesia. Endorectal ultrasound best evaluates rectal muscle invasion, while pelvic MRI and CT will evaluate the full extent of pelvic involvement and other GI sites of implantation. Only radical extirpative surgery of all intestinal, urologic, deep pelvic, and adnexal sites of endometriosis will permit relief of pain, prevent recurrence, and hopefully preserve fertility. In view of the frequency of extra-intestinal sites of involvement and technical difficulties augmented by previous surgical interventions, open laparotomy remains the preferred approach. A laparascopic approach would be reserved only for well-selected patients presenting with isolated colorectal involvement.
