RESUMEN

BACKGROUND: In the decision to perform elective surgery, it is of great interest to have data about the outcomes of surgery to individualize patients who could safely undergo sigmoid resection. The aim of this study was to provide information on the outcomes of elective sigmoid resection for sigmoid diverticular disease (SDD) at a national level. METHODS: All consecutive patients who had elective surgery for SDD (2010-2021) were included in this retrospective, multicenter, cohort study. Patients were identified from institutional review board-approved databases in French member centers of the French Surgical Association. The endpoints of the study were the early and the long-term postoperative outcomes and an evaluation of the risk factors for 90-day severe postoperative morbidity and a definitive stoma after an elective sigmoidectomy for SDD. RESULTS: In total, 4617 patients were included. The median [IQR] age was 61 [18.0;100] years, the mean ± SD body mass index (BMI) was 26.8 ± 4 kg/m2, and 2310 (50%) were men. The indications for surgery were complicated diverticulitis in 50% and smoldering diverticulitis in 47.4%. The procedures were performed laparoscopically for 88% and with an anastomosis for 83.8%. The severe complication rate on postoperative day 90 was 11.7%, with a risk of anastomotic leakage of 4.7%. The independent risk factors in multivariate analysis were an American Society of Anesthesiologists (ASA) score ≥ 3, an open approach, and perioperative blood transfusion. Age, perioperative blood transfusion, and Hartmann's procedure were the three independent risk factors for a permanent stoma. CONCLUSIONS: This series provides a real-life picture of elective sigmoidectomy for SDD at a national level. TRIAL REGISTRATION: Comité National Information et Liberté (CNIL) (n°920361).

RESUMEN

BACKGROUND: The aim of this study was to perform a systematic review of the literature on and updated meta-analysis of surgical postoperative complications after laparoscopic Hartmann's reversal (LHR) and open Hartmann's reversal (OHR). METHODS: Studies comparing LHR versus OHR published from inception until June 2020 were selected and submitted to a systematic review and meta-analysis. Articles were searched in the MEDLINE and Cochrane Trials Register databases. Meta-analysis was performed with Review Manager 5.0. RESULTS: Twenty-three retrospective comparative studies (including 5 case-controlled studies) with a total of 3139 patients with LHR and a total of 10,325 patients with OHR were included. Meta-analysis showed that LHR was significantly associated with a decreased rate of revision surgery (OR = 0.73, 95% CI = 0.60-0.89, p < 0.001), anastomotic leakage (OR = 0.61, 95% CI = 0.49-0.75, p < 0.00001), postoperative morbidity (OR = 0.53, 95% CI = 0.47-0.58, p < 0.00001), intra-abdominal abscess (OR = 0.67 [0.52-0.87], 95% CI = , p = 0.003), wound abscess (OR = 0.53 [0.46-0.61], 95% CI = , p < 0.00001), and postoperative ileus (OR = 0.46, 95% CI = 0.29-0.72, p = 0.0008), respectively. Conversely, mortality was comparable between LHR and OHR. CONCLUSIONS: These results suggest that LHR significantly improved surgical postoperative outcomes. However, considering the low level of evidence, further randomized trials are required to validate these findings.

RESUMEN

BACKGROUND: The aim of this study was to compare long-term survival after laproscopic completed and laparoscopic converted rectal resection for cancer. METHODS: All consecutive patients who underwent curative laparoscopic rectal surgery for cancer at our institution between January 2001 and December 2016 were included in a single-center retrospective study. Patients were divided into two groups: the converted (CONV) group and the totally laparoscopic (LAP) group. The primary outcomes were long-term oncologic outcomes including overall survival (OS) and disease-free survival (DFS), as well as local and distant recurrence (LR, DR). The secondary outcomes included postoperative mortality and morbidity as defined as death or any complication occurring within 90 days postoperatively. RESULTS: Of 214 consecutive patients included, 57 were converted to open surgery (CONV group), leading to a 26.6% conversion rate. Mean length of follow-up was 68 ± 42 months in the LAP group and 70 ± 41 months in the CONV group. Five-year OS was significantly shorter in the CONV group compared to the LAP group (p = 0.0016). On multivariate analysis, rectal tumor location (middle and low) and conversion to open surgery were predictors of both OS and DFS. CONCLUSIONS: This study suggests that conversion to open surgery after laparoscopic rectal resection appears to significantly reduce OS without having a significant impact on DFS and recurrence rates.

RESUMEN

BACKGROUND: Transanal local excision (TLE) has become the treatment of choice for benign and early-stage selected malignant tumors. However, closure of the rectal wall defect remains a controversial point and the available literature still remains unclear. Our aim was to determine through a systematic review of the literature and a meta-analysis of relevant studies whether or not the wall defect following TLE of rectal tumors should be closed. METHODS: Medline and the Cochrane Trials Register were searched for trials published up to December 2016 comparing open versus closed management of the surgical rectal defect after TLE of rectal tumors. Meta-analysis was performed using Review Manager 5.0. RESULTS: Four studies were analyzed, yielding 489 patients (317 in the closed group and 182 in the open group). Meta-analysis showed no significant difference between the closed and open groups regarding the overall morbidity rate (OR 1.26; 95% CI 0.32-4.91; p = 0.74), postoperative local infection rate (OR 0.62; 95% CI 0.23-1.62; p = 0.33), postoperative bleeding rate (OR 0.83; 95% CI 0.29-1.77; p = 0.63), and postoperative reintervention rate (OR 2.21; 95% CI 0.52-9.47; p = 0.29). CONCLUSIONS: This review and meta-analysis suggest that there is no difference between closure or non-closure of wall defects after TLE.

RESUMEN

BACKGROUND: Hepatocellular carcinoma in noncirrhotic liver (HCCNC) is rare. This tumor has a particular epidemiology and presentation, and it requires specific treatment, compared with HCC in cirrhotic liver. The aims of this study were to determine the survival and recurrence rates, prognostic factors, and optimum treatment of HCCNC and to propose a follow-up protocol for patients who have undergone surgery for HCCNC. METHODS: This study included 131 patients who underwent surgical treatment for HCCNC from January 1992 to December 2010. Survival and recurrence rates were evaluated, and the prognostic factors and characteristics of recurrence were analyzed. Pathologic characteristics of the tumors and the nontumoral liver were examined. RESULTS: The mean survival time was 67.9 months. The 5- and 10-year overall survival rates were 72.9 and 36.7 %, respectively. In all, 54 patients (41.2 %) developed recurrence at a median interval of 30.96 months. Of these recurrences, 31.5 % occurred during the first year, and 24.1 % occurred more than 5 years after surgery. Macro- or microvascular invasion and tumor size >5 cm were significantly associated with a poor survival rate. The predictive factors for recurrence were multiple tumors, tumor diameter >5 cm, and satellite nodules. Patients who underwent surgical treatment for recurrence had a significantly longer survival time than those who did not (p < 0.0292). CONCLUSIONS: Recurrence is the most common cause of death after hepatectomy for HCC, and patients should undergo careful, long-term follow-up. Early detection and treatment of recurrence with curative intent should improve the prognosis of these patients.

RESUMEN

Bariatric surgery is now recognized as the most effective treatment of morbid obesity, leading to durable weight loss and resolution of associated co-morbidities. Roux-en-Y gastric bypass and sleeve gastrectomy are the two most widely used operations today. However, potentially serious medical, surgical, and/or psychiatric complications can occur that raise questions regarding the benefits of this type of surgery. These complications can lead to surgical re-operations, iterative hospitalizations, severe nutritional deficiencies and psychological disorders. Indeed, death from suicide is said to be three times higher than in non-operated obese patients. These results are of concern, all the more because of the high prevalence of patients lost to follow-up (for various and multifactorial reasons) after bariatric surgery. However, better knowledge of post-surgical sequelae could improve the information provided to patients, the preoperative evaluation of the benefit/risk ratio, and, for patients undergoing surgery, the completeness and quality of follow-up as well as the detection and management of complications. The development of new strategies for postoperative follow-up such as telemedicine but also the mobilization of all the actors along the healthcare pathway can make inroads and warrant further study.

RESUMEN

Bariatric revisional surgery represents an important new issue for obese patients because of the considerable rate of failure and complications following bariatric surgery. As the frequency of bariatric procedures increases, so too does the incidence of revisional surgery, which has become becoming increasingly important. The surgeon must know the indications and the results of the various revisional procedures in order to best guide the therapeutic decision. The current challenge is to correctly select the patients for revisional surgery and to choose the appropriate procedure in each case. Multidisciplinary management is essential to patient re-assessment and to prepare the patient for a re- intervention. The objective of this update, based on data from all the most recent studies concerning revisional surgery, is to guide the surgeon in the choice of the revisional procedure, depending on patient characteristics, co-morbidities, the previously performed procedure, the type of failure or complication observed, but also on the surgeon's own habits and the center's expertise. The collected results show that revisional surgery is difficult, with higher complication rates and weight-loss results that are often lower than those of first-intent surgery. For these reasons, patient selection must be rigorous and multidisciplinary and the management in expert centers of these difficult situations must be encouraged.

RESUMEN

Abdominal pelvic radiation therapy can induce acute or chronic lesions in the small bowel wall, called radiation enteritis. Treatment of acute radiation enteritis is essentially symptomatic; symptoms regress when radiation is discontinued. Conversely, late toxicity can occur up to 30 years after discontinuation of radiation therapy, posing diagnostic problems. Approximately one out of five patients treated by radiation therapy will present clinical signs of radiation enteritis, including obstruction, malabsorption, malnutrition and/or other complications. Management should be multidisciplinary, centered mainly on correction of malnutrition. Surgery is indicated in case of complications (i.e., abscess, perforation, fistula) and/or resistance to medical treatment; intestinal resection should be preferred over internal bypass. The main risk in case of iterative resections is the short bowel syndrome and the need for definitive nutritional assistance.

RESUMEN

Nearly 5% of colorectal cancers are hereditary colorectal cancers, including adenomatous polyposis. The aim of this review was to highlight the current management of adenomatous polyposis. The two main genetic conditions responsible for adenomatous polyposis are familial adenomatous polyposis (FAP) (caused by an autosomal dominant mutation of the APC gene) and MUTYH-associated polyposis (MAP) (caused by bi-allelic recessive mutations of the MUTYH (MutY human homolog) gene). FAP is characterized by the presence of >1000 polyps and a young age at diagnosis (mean age of 10). In the absence of screening, the risk of colorectal cancer at age 40 is 100%. It is recommended to start screening at the age of 10-12 years. For patients with FAP and MAP, it is also recommended to screen the upper gastrointestinal tract (stomach and duodenum). In FAP, prophylactic surgery aims to reduce the risk of death without impairment of patient quality of life. The best age for prophylactic surgery is not well-defined; in Europe, prophylactic surgery is usually performed at age 20 as the risk of cancer increases sharply during the third decade. There are three main surgical procedures employed: total colectomy with an ileorectal anastomosis, restorative coloproctectomy with a J pouch anastomosis and coloproctectomy with a stoma. Restorative coloproctectomy with J pouch anastomosis is the reference procedure; however, disease can vary in severity from one patient to another and this must be taken into account to decide which procedure should be performed. In conclusion, the management of adenomatous polyposis is complex but is well-defined by guidelines, particularly in France.

RESUMEN

OBJECTIVE: To evaluate, regarding previous published studies, postoperative outcomes between patients undergoing rectal cancer resection performed by totally laparoscopic approach (LAP) compared to those who underwent peroperative conversion (CONV). METHODS: Studies comparing LAP versus CONV for rectal cancer published until December 2017 were selected and submitted to a systematic review and meta-analysis. Articles were searched in Medline and Cochrane Trials Register Database. Meta-analysis was performed with Review Manager 5.0. RESULTS: Twelve prospective and retrospective studies with a total of 4503 patients who underwent fully laparoscopic approach for rectal cancer and a total of 612 patients who underwent conversion were included. Meta-analysis did not show any significant difference on overall mortality between both approaches (OR=0.47, 95%CI=0.18-1.22, P=0.12). However, Meta-analysis showed that anastomotic leakage rate, wound abscess rate and postoperative morbidity rate were significantly decreased with totally laparoscopic approach (OR=0.37, 95%CI =0.24-0.58, P<0.0001; OR=0.29, 95%CI=0.19-0.45, P<0.00001; OR=0.56, 95%CI=0.46-0.67, P<0.00001 respectively). CONCLUSION: This meta-analysis suggests that conversion increases anastomotic leakage, overall morbidity and wound abscess rates without increasing mortality rate for patients who underwent rectal resection for cancer.

RESUMEN

Nearly 5% of colorectal cancers are related to constitutional genetic abnormalities. In Lynch Syndrome (LS), the abnormality is a mutation of the deoxyribonucleic acid (DNA) repair system. The goal of this update is to update indications and surgical strategies for patients with LS. Different spectra of disease are associated with LS. The narrow spectrum includes cancers with a high relative risk: colorectal cancer (CRC), endometrial cancer, urinary tract cancers and small intestinal cancer. The broader spectrum includes ovarian tumors, glioblastoma, cutaneous tumors (keratoacanthomas and sebaceous tumors), biliary duct tumors, and gastric tumors. The clinical diagnosis of LS was initially based on the Amsterdam I and II Criteria published in the 1990s and subsequently on the revised Bethesda Criteria, which expanded the criteria and identified patients who should be screened for LS. For patients with LS, learned societies recommend early and regular endoscopic screening because of the high incidence of CRC, i.e., every one to two years from the age of 25 and then annually from the age of 40 or starting 10 years before the age of appearance of the youngest case of CRC in the family. Professional recommendations on prophylactic surgery to prevent cancers in patients with genetic predisposition were published in 2009 under the auspices of the French National Cancer Institute and are still current. There is no formal indication for prophylactic colectomy in LS. Numerous advances have been made in the understanding of LS, allowing a better knowledge of the prevalence of CRCs and associated cancers, with better endoscopic monitoring and a decrease in the prevalence and mortality of CRC.

RESUMEN

BACKGROUND: Transjugular intrahepatic portosystemic shunt (TIPS) has been suggested to reduce portal hypertension-associated complications in cirrhotic patients undergoing abdominal surgery. The aim of this study was to compare postoperative outcome in cirrhotic patients with and without specific preoperative TIPS placement, following elective extrahepatic abdominal surgery. METHODS: Patients were retrospectively included from 2005 to 2016 in four centers. Patients who underwent preoperative TIPS (n = 66) were compared to cirrhotic control patients without TIPS (n = 68). Postoperative outcome was analyzed using propensity score with inverse probability of treatment weighting analysis. RESULTS: Overall, colorectal surgery accounted for 54% of all surgical procedure. TIPS patients had a higher initial Child-Pugh score (6[5-12] vs. 6[5-9], p = 0.043) and received more beta-blockers (65% vs. 22%, p < 0.001). In TIPS group, 56 (85%) patients managed to undergo planned surgery. Preoperative TIPS was associated with less postoperative ascites (hazard ratio = 0.330 [0.140-0.780]). Severe postoperative complications (Clavien-Dindo > 2) and 90-day mortality were similar between TIPS and no-TIPS groups (18% vs. 23%, p = 0.392, and 7.5% vs. 7.8%, p = 0.644, respectively). CONCLUSIONS: Preoperative TIPS placement yielded an 85% operability rate with satisfying postoperative outcomes. No significant differences were found between TIPS and no-TIPS groups in terms of severe postoperative complications and mortality, although TIPS patients probably had worse initial portal hypertension.

RESUMEN

INTRODUCTION: In 2006 under the supervision of the French health authorities (HAS), recommendations for clinical practice (RCP) in the management of rectal cancers were first published. The primary objective of this study was to assess the impact of these guidelines on multidisciplinary management in terms of therapeutic strategies based on disease staging and quality indicators for surgical excision. Secondarily, we assessed the impact of the RCPs on postoperative and oncological outcomes. METHODS: All consecutive patients having undergone curative surgical excision for middle and low (subperitoneal) rectal cancer from 1995 to 2017 in the university hospital of Caen were included in accordance with the relevant French guidelines. They were divided into two groups: before (Gr1) and after (Gr2) 2006. For each group, a chart review was conducted on demographic variables, preoperative rectal tumor features, disease severity variables and quality of surgery variables. Postoperative and oncological outcomes were likewise assessed and compared between the two groups. RESULTS: Six hundred and four patients were included (Gr1, n=266; Gr2, n=338). Compliance with French guidelines significantly improved (i) use of magnetic resonance imaging (P<0.0001) and CT-scan (P<0.0001)]; (ii) organization of multidisciplinary tumor boards (P<0.0001) leading to suitable neo-adjuvant treatment plan classification (P<0.0001). Consequently, compliance improved widespread total mesorectal excision (P<0.0001), sphincter-sparing surgery (P=0,0005), and completeness of curative resection in the specimen (P<0.0001). Although postoperative 90-day mortality was similar, overall postoperative morbidity significantly increased in Gr2 (P<0.0001). Overall (P=0.0005) and disease-free survival (P=0.0016) of patients in Gr2 were significantly prolonged and correlated with a significant reduction in local and distant recurrences. CONCLUSION: Compliance with the relevant French guidelines improved the quality of multidisciplinary management of patients undergoing curative surgery for subperitoneal rectal cancer. However, further progress is still needed to render accession to the recommendations more comprehensive.

RESUMEN

Adolescence is a time of significant brain development, and exposure to nicotine during this period is associated with higher subsequent rates of dependence. Chronic nicotine exposure alters expression of nicotinic acetylcholine receptors (nAChRs), changing the pattern of nicotine responsiveness. We used quantitative autoradiography to measure three major subtypes of nAChRs after chronic nicotine exposure by osmotic minipump in adult and periadolescent rats. Comparison of control animals at the two different ages revealed that periadolescents express consistently greater numbers of alpha4beta2* nAChRs compared to the same brain regions of adults. Similar but less pronounced increases in alpha7 nAChRs were found in control periadolescent rats compared to adults. Binding of [(125)I]alpha-conotoxin MII (largely to alpha6* nAChRs) did not systematically differ between adults and periadolescents. The response to chronic nicotine exposure also differed by age. Up-regulation of alpha4beta2* nAChRs was prominent and widespread in adult animals; in periadolescents, alpha4beta2* up-regulation also occurred, but in fewer regions and to a lesser extent. A similar pattern of response was seen with alpha7 receptors: adults were more responsive than periadolescents to nicotine-induced up-regulation. In adult animals, chronic nicotine exposure did not cause up-regulation of alpha6* nAChRs; binding was down-regulated in three regions. Unlike the other subtypes, the response of alpha6* nAChRs to chronic nicotine was greater in periadolescents, with more regions showing greater down-regulation compared to adults. These differences in receptor expression and regulation between age groups are likely to be important given the unique vulnerability of adolescents to nicotine-induced behavioral changes and susceptibility to drug abuse.

RESUMEN

BACKGROUND: Transanal excision (TAE) is increasingly used in the treatment of early rectal cancer because of lower rate of both postoperative complications and postsurgical functional disorders as compared with total mesorectal excision (TME) OBJECTIVE: To compare in a meta-analysis surgical outcomes and pathologic findings between patients who underwent TAE followed by completion proctectomy with TME (TAE group) for early rectal cancer with unfavorable histology or incomplete resection, and those who underwent primary TME (TME group). METHODS: The Medline and Cochrane Trials Register databases were searched for studies comparing short-term outcomes between patients who underwent TAE followed by completion TME versus primary TME. Studies published until December 2016 were included. The meta-analysis was performed using Review Manager 5.0 (Cochrane Collaboration, Oxford, UK). RESULTS: Meta-analysis showed that completion TME after TAE was significantly associated with increased reintervention rate (OR=4.28; 95% CI, 1.10-16.76; P≤0.04) and incomplete mesorectal excision rate (OR=5.74; 95% CI, 2.24-14.75; P≤0.0003), as compared with primary TME. However there both abdominoperineal amputation and circumferential margin invasion rates were comparable between TAE and TME groups. CONCLUSIONS: This meta-analysis suggests that previous TAE impaired significantly surgical outcomes and pathologic findings of completion TME as compared with primary TME.

RESUMEN

Multidisciplinary management of infra-peritoneal rectal cancer has pushed back the frontiers of sphincter preservation, without impairment of carcinological outcome. However, functional intestinal sequelae, grouping together several symptoms known under the name of anterior resection syndrome (ARS), have emerged and become an increasingly frequent concern for both patients and physicians. The pathophysiology is complex: ARS is a combination in various degrees of stool frequency, incontinence for flatus and/or stools, urgency, and disorders in discrimination and evacuation. The "Low Anterior Resection Score" (LARS), validated in 2012, is currently used to evaluate the severity of ARS and its impact on quality of life. While ARS can show improvement over the first two years, symptoms persist for longer than two years in nearly 60% of patients and in half of these patients, ARS is considered severe. The most frequently reported independent risk factors of severe ARS include neo-adjuvant radiation therapy, the extent of resection (total mesorectal excision that includes inter-sphincteric resection), absence of colonic pouch and anastomotic leak. In the absence of surgical complications and/or local recurrence, physicians can draw from a wide therapeutic armamentarium in order to improve the functional outcome of patients, including diet and lifestyle modifications, gut motility regulators, multimodal rehabilitation (biofeedback, electro-stimulation) and sacral nerve modulation. Permanent colostomy is an alternative of last resort, proposed only when all other solutions fail. A better understanding of the natural history of ARS, its risk factors as well as the array of therapeutic alternatives should provide better patient information and optimize management.

RESUMEN

Complications in bariatric surgery are varied; they are severe at times but infrequent. They may be surgical or non-surgical, and may occur early or late. The goal of this systematic review is to inform and help the attending physician, the emergency physician and the non-bariatric surgeon who may be called upon to manage surgical complications that arise after adjustable gastric band (AGB), sleeve gastrectomy (SG), or gastric bypass (GBP). Data from evidence-based medicine were extracted from the literature by a review of the Medline database and also of the most recent recommendations of the learned societies implicated. The main complications were classified for each intervention, and a distinction was made between early and late complications. Early complications after AGB include prosthetic slippage or perforation; SG can be complicated early by staple line leak or fistula, and BPG by fistula, stenosis and postoperative hemorrhage. Delayed complications of AGB include intragastric migration of the prosthesis, late prosthetic slippage and infection, while SG can be complicated by gastro-esophageal reflux, and BPG by anastomotic ulcer and internal hernia. The analysis of available data allowed us to develop decisional algorithms for the management of each of these complications.

RESUMEN

OBJECTIVE: To evaluate long-term (5- and 10-year) survival and recurrence rates on the basis of the pathological complete response (pCR) in the specimens of patients with esophageal carcinoma, treated with trimodality therapy. METHODS: Between 1993 and 2014, all consecutives patients with esophageal locally-advanced non-metastatic squamous cell carcinoma (SCC) or adenocarcinoma (ADC) who received trimodality therapy were reviewed. According to histopathological analysis, patients were divided in two groups with pCR and with pathological residual tumor (pRT). The primary endpoint was overall survival (OS). The secondary endpoints included the disease-free survival (DFS), the recurrence rate, and the predictive factors of overall survival and recurrence. RESULTS: One hundred and three patients were included: 49 patients with pCR and 54 patients with pRT. The median OS was significantly longer in pCR group than in pRT group (132±22.3 vs. 25.5±4 months), with both 5- and 10-years OS rates of 75.2% vs. 29.1%, and 51.1% vs. 13.6%, respectively (P<0.001). Also, pRT, major postoperative complications (Dindo-Clavien grade>IIIb) and recurrence were the 3 independent predictive factors for worse OS. CONCLUSIONS: Patients with locally-advanced oesophageal carcinoma, who responded to trimodality therapy with a pCR, could be achieved a 10-year survival rate of 51%.

RESUMEN

Although we have seen revolutionary changes with multi-disciplinary management of patients with rectal cancer, the evaluation of genito-urinary sequelae remains of great concern. Precise pre-operative evaluation with validated scores allows detection of urinary disorders in 16 to 23% of patients, and sexual disorders in nearly 35% of men and 50% of women. Regardless of the surgical approach, it is fundamental to respect the autonomic innervation during total mesorectal excision in order to prevent these sequelae. Identification of these nerves can be facilitated by intra-operative neuro-stimulation. In spite of these precautions, de novo urinary sequelae are observed in nearly 33% of patients and bladder evacuation disorders in 25% of patients. Advanced age, pre-operative urinary disorders, female gender, and abdomino-perineal resection are independent risk factors for urinary sequelae. Early post-operative urodynamic abnormalities might be predictive of these sequelae and justify early physiotherapy. Likewise, sexual sequelae such as erectile and/or ejaculatory disorders, dyspareunia and lubrication deficits result in de novo cessation of sexual activity in 28% of men and 18% of women. Advanced age, neo-adjuvant radiation therapy, and abdomino-perineal resection are independent risk factors for sexual dysfunction. Pharmacotherapy with sildenafil has proven useful in the treatment of erectile disorders. Genito-urinary and ano-rectal sequelae occur concomitantly in more than one of ten patients, suggesting a potential common pathophysiology.

RESUMEN

Meckel's diverticulum (MD) is the most common gastro-intestinal congenital malformation (approximately 2% in the overall population). The lifetime risk of related complications is estimated at 4%. These include gastro-intestinal bleeding, obstruction or diverticular inflammation. Diagnosis is difficult and rarely made, and imaging, especially in the case of complicated disease, is often not helpful; however exploratory laparoscopy is an important diagnostic tool. The probability of onset of complication decreases with age, and the diagnosis of MD in the adult is therefore often incidental. Resection is indicated in case of complications but remains debatable when MD is found incidentally. According to an analysis of large series in the literature, surgery is not indicated in the absence of risk factors for complications: these include male gender, age younger than 40, diverticulum longer than two centimetres and the presence of macroscopically mucosal alteration noted at surgery. Resection followed by anastomosis seems preferable to wedge resection or tangential mechanical stapling because of the risk of leaving behind abnormal heterotopic mucosa.
