Updated European guidelines for clinical management of familial adenomatous polyposis (FAP), MUTYH-associated polyposis (MAP), gastric adenocarcinoma, proximal polyposis of the stomach (GAPPS) and other rare adenomatous polyposis syndromes: a joint EHTG-ESCP revision.

BACKGROUND: Hereditary adenomatous polyposis syndromes, including familial adenomatous polyposis and other rare adenomatous polyposis syndromes, increase the lifetime risk of colorectal and other cancers. METHODS: A team of 38 experts convened to update the 2008 European recommendations for the clinical management of patients with adenomatous polyposis syndromes. Additionally, other rare monogenic adenomatous polyposis syndromes were reviewed and added. Eighty-nine clinically relevant questions were answered after a systematic review of the existing literature with grading of the evidence according to Grading of Recommendations, Assessment, Development, and Evaluation methodology. Two levels of consensus were identified: consensus threshold (≥67% of voting guideline committee members voting either 'Strongly agree' or 'Agree' during the Delphi rounds) and high threshold (consensus ≥ 80%). RESULTS: One hundred and forty statements reached a high level of consensus concerning the management of hereditary adenomatous polyposis syndromes. CONCLUSION: These updated guidelines provide current, comprehensive, and evidence-based practical recommendations for the management of surveillance and treatment of familial adenomatous polyposis patients, encompassing additionally MUTYH-associated polyposis, gastric adenocarcinoma and proximal polyposis of the stomach and other recently identified polyposis syndromes based on pathogenic variants in other genes than APC or MUTYH. Due to the rarity of these diseases, patients should be managed at specialized centres.

Rectovaginal Fistula: What Is the Role of Martius Flap and Gracilis Muscle Interposition in the Therapeutic Strategy?

BACKGROUND: Although numerous treatments exist for the management of rectovaginal fistula, none has demonstrated its superiority. The role of diverting stoma remains controversial. A few series include Martius flap in the armamentarium. OBJECTIVE: Determine the role of gracilis muscle interposition and Martius flap in the surgical management of rectovaginal fistula. DESIGN: Retrospective cohort study of a pooled prospectively maintained database from 3 centers. PATIENTS: All consecutive eligible patients with rectovaginal fistula undergoing Martius flap and gracilis muscle interposition were included from 2001 to 2022. MAIN OUTCOME MEASURES: Success was defined by the absence of stoma and rectovaginal fistula. RESULTS: Sixty-two patients were included with 55 Martius flap and 24 gracilis muscle interposition performed after failures of 164 initial procedures. Total length of stay was longer for gracilis muscle interposition by 2 days ( p = 0.01) without a significant difference in severe morbidity (20% vs 12%, p = 0.53). Twenty-seven percent of the Martius flap interpositions were performed without a stoma, which did not have an impact on overall morbidity ( p = 0.763). Per patient immediate success rates were not significantly different between groups (35% vs 31%, p > 0.99). The success of gracilis muscle interposition after the failure of the Martius flap was not significantly different from an initial gracilis muscle interposition ( p > 0.99). After simple perineal procedures, the immediate success rate rose to 49.4% (49% vs 50%, p > 0.99). After a median follow-up of 23 months, no significant difference was detected in success rate between the 2 procedures (69% vs 69%, p > 0.99). Smoking was the only negative predictive factor ( p = 0.02). LIMITATIONS: By its retrospective nature, this study is limited in its comparison. CONCLUSIONS: This novel comparison between Martius flap and gracilis muscle interposition suggests that Martius flap presents several advantages, including shorter length of stay, similar morbidity, and similar success rate. Proximal diversion via a stoma for Martius flap does not appear mandatory. Gracilis muscle interposition could be reserved as a salvage procedure after Martius flap failure. See Video Abstract . FSTULA RECTOVAGINAL CUL ES EL ROL DEL COLGAJO DE MARTIUS Y LA INTERPOSICIN DEL MSCULO GRACILIS EN LA ESTRATEGIA TERAPUTICA: ANTECEDENTES:Si bien existen numerosos tratamientos para el manejo de la fistula rectovaginal, ninguno ha demostrado su superioridad. El papel del estoma de derivación sigue siendo controvertido. Pocas series incluyen colgajo de Martius en el armamento.OBJETIVO:Determinar el rol de la interposición del músculo gracilis y del colgajo de Martius, en el manejo quirúrgico de la fístula rectovaginal.DISEÑO:Estudio de cohorte retrospectivo de una base de datos mantenida prospectivamente en 3 centros.AJUSTES/PACIENTES:Se incluyeron todos los pacientes elegibles consecutivos con fistula rectovaginal sometidos a colgajo de Martius y la interposición del músculo gracilis desde 2001 hasta 2022.RESULTADOS PRINCIPALES:El éxito se definió por la ausencia de estoma y fistula rectovaginal.RESULTADOS:Se incluyeron 62 pacientes con 55 colgajo de Martius y 24 con interposición del músculo gracilis realizados después de fracasos de 164 procedimientos iniciales. La duración total de la estancia hospitalaria fue dos días más larga para la interposición del músculo gracilis ( p = 0,01) sin una diferencia significativa en la morbilidad grave (20% frente a 12%, p = 0,53). El 27% de los colgajos de Martius se realizaron sin estoma, sin impacto en la morbilidad global ( p = 0,763). Las tasas de éxito inmediato por paciente no fueron significativamente diferentes entre los grupos (35% vs. 31%, p = 1,0). El éxito de la interposición del músculo gracilis después del fracaso del colgajo de Martius no fue significativamente diferente de una interposición del músculo gracilis inicial (p = 1,0). La tasa de éxito inmediato aumentó al 49,4% (49% frente a 50%, p = 1,0) después de procedimientos perineales simples. Después de una mediana de seguimiento de 23 meses, no se detectaron diferencias significativas en la tasa de éxito entre los dos procedimientos (69 % frente a 69 %, p = 1,0). El tabaquismo fue el único factor predictivo negativo ( p = 0,02).LIMITACIONES:Por su naturaleza retrospectiva, este estudio tiene limitaciones en su comparación.CONCLUSIÓN:Esta novedosa comparación entre colgajo de Martius y la interposición del músculo gracilis sugiere que el colgajo de Martius presenta varias ventajas, incluida una estancia prolongada más corta, una morbilidad similar y un éxito. La derivación proximal a través de un estoma para el colgajo de Martius no parece obligatoria. La interposición del músculo gracilis podría reservarse como procedimiento de rescate después de una falla de colgajo de Martius. (Traducción-Dr. Aurian Garcia Gonzalez ).

Impact of diverting ileostomy on functional outcome and quality of life after restorative proctocolectomy and ileal pouch anal anastomosis.

AIM: Diverting ileostomy (DS) after restorative proctocolectomy (RPC) can be omitted in selected patients. Its omission could improve functional outcomes and quality of life (QoL), as has been demonstrated in patients after proctectomy. The aim of this study was to report the impact of diverting ileostomy on functional outcomes and QoL after ileal pouch-anal anastomosis (IPAA). METHODS: This was a retrospective study including all patients operated (2015-2020) for RPC with IPAA. Functional outcome was evaluated by validated scores (LARS, Wexner, Öresland, pouch functional score [PFS] and the ileoanal pouch syndrome severity [IPSS] score). Global health-related QoL was evaluated with the SF-36. We also analysed demographic characteristics, morbidity, correlation between functional outcomes and QoL. RESULTS: Among 179 eligible patients, 150 responded (84%): S- (no stoma = 78; 52%) and S+ (had stoma = 72; 48%). Overall morbidity and anastomotic leak rates were 46% and 9.3%, respectively without difference between the groups. Medians for the functional scores were comparable between the S- and S+ group, respectively: 18 [12.5-31] versus 18 [11-31], p = 0.48 for LARS; 9 [7-11] versus 9 [7-12], p = 0.23 for Wexner's score; 6 [3-13] versus 8 [5-11], p = 0.22 for Öresland's score, 6 [3-13] versus 6.8 [4-12], p = 0.174 for PFS score, and 40 [35-45] versus 46 [42-51], p = 0.045 for IPSS score. The SF-36 summary score was comparable between the two groups without any difference in eight specific health dimensions. After propensity score matching, results were still comparable between the two groups for all scores. Linear regression found a significant correlation between all QoL domains and all functional scores (p < 0.001). CONCLUSION: DS for IPAA does not alter either functional outcomes or QoL and can be omitted in selected patients.

What is the rate of definitive stoma after subtotal colectomy for inflammatory bowel disease? A nationwide study of 1860 patients.

AIM: Some patients with inflammatory bowel disease (IBD) require subtotal colectomy (STC) with ileostomy. The recent literature reports a significant number of patients who do not undergo subsequent surgery and are resigned to living with a definitive stoma. The aim of this work was to analyse the rate of definitive stoma and the cumulative incidence of secondary reconstructive surgery after STC for IBD in a large national cohort study. METHOD: A national retrospective study (2013-2021) was conducted on prospectively collected data from the French Medical Information System Database (PMSI). All patients undergoing STC in France were included. The association between definitive stoma and potential risk factors was studied using univariate and multivariate analyses. RESULTS: A total of 1860 patients were included (age 45 ± 9 years; median follow-up 30 months). Of these, 77% (n = 1442) presented with ulcerative colitis. Mortality and morbidity at 90 days after STC were 5% (n = 100) and 47% (n = 868), respectively. Reconstructive surgery was identified in 1255 patients (67%) at a mean interval of 7 months from STC. Seveny-four per cent (n = 932) underwent a completion proctectomy with ileal pouch anal anastomosis and 26% (n = 323) an ileorectal anastomosis. Six hundred and five (33%) patients with a definitive stoma had an abdominoperineal resection (n = 114; 19%) or did not have any further surgical procedure (n = 491; 81%). Independent risk factors for definitive stoma identified in multivariate analysis were older age, Crohn's disease, colorectal neoplasia, postoperative complication after STC, laparotomy and a low-volume hospital. CONCLUSION: We found that 33% of patients undergoing STC with ileostomy for IBD had definitive stoma. Modifiable risk factors for definitive stoma were laparotomy and a low-volume hospital.

Does an Ileoanal Anastomosis Decrease the Rate of Successful Pregnancy Compared With an Ileorectal Anastomosis? A National Study of 1491 Patients.

OBJECTIVE: Report the rate of successful pregnancy in a national cohort of women with either an ileal pouch anal (IPAA) or ileorectal (IRA) anastomosis constructed after colectomy for inflammatory bowel disease (IBD) or polyposis. BACKGROUND: Fertility after IPAA is probably impaired. All available data are corroborated by only small sample size studies. It is not known whether construction of IPAA versus IRA influences the odds of subsequently achieving a successful pregnancy, especially with increased utilization of the laparoscopic approach. METHODS: All women (age: 12-45 y) undergoing IRA or IPAA in France for polyposis or IBD, between 2010-2020, were included. A control population was defined as women aged from 12 to 45 years undergoing laparoscopic appendicectomy during the same period. The odds of successful pregnancy were studied using an adjusted survival analysis. RESULTS: A total of 1491 women (IPAA=872, 58%; IRA=619, 42%) were included. A total of 220 deliveries (15%) occurred during the follow-up period of 71 months (39-100). After adjustment, the odds of successful pregnancy was not significantly associated with type of anastomosis (after IPAA: Hazard Ratio [HR]=0.79, 95% confidence interval=0.56-1.11, P =0.17). The laparoscopic approach increased the odds of achieving successful pregnancy (HR=1.79, 95% confidence interval=1.20-2.63, P =0.004). IRA and IPAA significantly impacted fertility when compared with the control population ( P <0.001). CONCLUSIONS: In this large cohort study, total colectomy for polyposis or IBD was associated with reduced fertility compared with the general population. No difference in odds of achieving successful pregnancy was found between IRA and IPAA after adjustment. This analysis suggests laparoscopic surgery may be associated with greater likelihood of pregnancy.

Is Delaying a Coloanal Anastomosis the Ideal Solution for Rectal Surgery?: Analysis of a Multicentric Cohort of 564 Patients From the GRECCAR.

OBJECTIVES: To assess the specific results of delayed coloanal anastomosis (DCAA) in light of its 2 main indications. BACKGROUND: DCAA can be proposed either immediately after a low anterior resection (primary DCAA) or after the failure of a primary pelvic surgery as a salvage procedure (salvage DCAA). METHODS: All patients who underwent DCAA intervention at 30 GRECCAR-affiliated hospitals between 2010 and 2021 were retrospectively included. RESULTS: Five hundred sixty-four patients (male: 63%; median age: 62 years; interquartile range: 53-69) underwent a DCAA: 66% for primary DCAA and 34% for salvage DCAA. Overall morbidity, major morbidity, and mortality were 57%, 30%, and 1.1%, respectively, without any significant differences between primary DCAA and salvage DCAA ( P = 0.933; P = 0.238, and P = 0.410, respectively). Anastomotic leakage was more frequent after salvage DCAA (23%) than after primary DCAA (15%), ( P = 0.016).Fifty-five patients (10%) developed necrosis of the intra-abdominal colon. In multivariate analysis, intra-abdominal colon necrosis was significantly associated with male sex [odds ratio (OR) = 2.67 95% CI: 1.22-6.49; P = 0.020], body mass index >25 (OR = 2.78 95% CI: 1.37-6.00; P = 0.006), and peripheral artery disease (OR = 4.68 95% CI: 1.12-19.1; P = 0.030). The occurrence of this complication was similar between primary DCAA (11%) and salvage DCAA (8%), ( P = 0.289).Preservation of bowel continuity was reached 3 years after DCAA in 74% of the cohort (primary DCAA: 77% vs salvage DCAA: 68%, P = 0.031). Among patients with a DCAA mannered without diverting stoma, 75% (301/403) have never required a stoma at the last follow-up. CONCLUSIONS: DCAA makes it possible to definitively avoid a stoma in 75% of patients when mannered initially without a stoma and to save bowel continuity in 68% of the patients in the setting of failure of primary pelvic surgery.

StomaCare: quality of life impact after enhanced follow-up of ostomy patients by a home healthcare nursing service-a multicentre, randomized, controlled trial.

AIM: A stoma exposes patients to several complications which could impair their quality of life (QoL). In the last decade, the market for stoma therapy in France has evolved, with a significant increase in the activities of home health providers, meeting a need for patient follow-up and companionship. International studies have demonstrated the impact of the stoma therapist (ST) follow-up on the improvement of an ostomy patient's QoL. However, the impact of home stoma nurse management has not been analysed. In this context we would like to assess the added value on health-related QoL from the enhanced follow-up of ostomy patients by STs. METHODS: This is a randomized, controlled, open, national and multicentre trial (12 centres) which includes patients with an ostomy who benefit from either standard follow-up or from an enhanced and personalized follow-up with, in particular, regular consultations with an ST after discharge. The primary end-point is the 3-month QoL score obtained from the Stoma-QoL questionnaire. The secondary end-points are satisfaction of the care, comparison of QoL scores (Stoma-QoL and EuroQuol EQ-5D) and the economic gains by calculating the consumption of resources between the two arms. There will be a modified intention-to-treat analysis with 6-month follow-up in both study arms. DISCUSSION: The StomaCare trial will be the first randomized controlled study in France to evaluate the impact on QoL of an enhanced follow-up at home of ostomy patients by an ST.

Surgery for synchronous and metachronous colorectal cancer: segmental or extensive colectomy?

PURPOSE: To assess the impact of surgical approach on morbidity, mortality, and the oncological outcomes of synchronous (SC) and metachronous (MC) colorectal cancer (CRC). METHODS: All patients undergoing resection for double location CRC (SC or MC) between 2006 and 2020 were included. The exclusion criteria were polyposis or SC located on the same side. RESULTS: Sixty-seven patients (age, 64.8 years; male, 78%) with SC (n = 41; 61%) or MC (n = 26; 39%) were included. SC was treated with segmental colectomy (right and left colectomy/proctectomy; n = 19) or extensive colectomy (subtotal/total colectomy or restorative proctocolectomy with pouch; n = 22). Segmental colectomy was associated with a higher incidence of anastomotic leakage (47.4 vs. 13.6%; p = 0.04) and a higher rate of medical morbidity (47.4 vs. 16.6%; p = 0.04). The mean number of lymph nodes harvested was similar. For MC, the second cancer was treated by iterative colectomy (n = 12) or extensive colectomy (n = 14) and there was no significant difference in postoperative outcomes between the two surgical approaches. The median follow-up period was 42.4 ± 29.1 months. The 5-year overall and disease-free survival of the SC and MC groups did not differ to a statistically significant extent. CONCLUSIONS: Extensive colectomy should be preferred for SC to reduce morbidity and improve the prognosis. In contrast, iterative colectomy can be performed safely for patients with MC.

Effective initial management of anastomotic leak in the maintenance of functional colorectal or coloanal anastomosis.

PURPOSE: The present study assessed the factors associated with the maintenance of a functional anastomosis in a large consecutive series of patients with anastomotic leakage (AL). METHODS: All consecutive patients presenting with AL after colorectal or coloanal anastomosis (2012-2019) were analyzed. The primary end point was a functional anastomosis without a stoma at 1 year. RESULTS: A total of 156 patients were included. AL was initially treated by antibiotics (38%), drainage (43%) or urgent surgery (19%). Initial treatment of AL was not adequate in 24.3%, and reintervention in the form of drainage or surgery was required. A total of 60.9% of patients had a functional anastomosis without a stoma 1 year after surgery. Factors associated with the risk of anastomotic failure at 1 year were diabetes (odds ratio [OR] = 4.24 [95% confidence interval {CI} 1.39-14.24] p = 0.014), neoadjuvant chemoradiotherapy (OR = 3.03 [95% CI 1.14-8.63] p = 0.03) and Grade B (OR = 6.49 [95% CI 2.23-21.74] p = 0.001) or C leak (OR = 35.35 [95% CI 9.36-168.21] p < 0.001). Among patients treated initially by drainage, side-to-end or J-pouch anastomoses were significantly associated with revision of the anastomosis compared to end-to-end (OR = 12.90, p = 0.04). CONCLUSION: After acute AL following coloanal or colorectal anastomosis, 60.9% of patients had a functional anastomosis without a stoma at the 1 year of follow-up. The type of treatment of AL influenced the risk of anastomotic failure.

Management of Pathogenic CDH1 Variant Carriers Within the FREGAT Network: A Multicentric Retrospective Study.

OBJECTIVE: To describe the management of pathogenic CDH1 variant carriers (pCDH1vc) within the FREGAT (FRench Eso-GAsTric tumor) network. Primary objective focused on clinical outcomes and pathological findings, Secondary objective was to identify risk factor predicting postoperative morbidity (POM). BACKGROUND: Prophylactic total gastrectomy (PTG) remains the recommended option for gastric cancer risk management in pCDH1vc with, however, endoscopic surveillance as an alternative. METHODS: A retrospective observational multicenter study was carried out between 2003 and 2021. Data were reported as median (interquartile range) or as counts (proportion). Usual tests were used for univariate analysis. Risk factors of overall and severe POM (ie, Clavien-Dindo grade 3 or more) were identified with a binary logistic regression. RESULTS: A total of 99 patients including 14 index cases were reported from 11 centers. Median survival among index cases was 12.0 (7.6-16.4) months with most of them having peritoneal carcinomatosis at diagnosis (71.4%). Among the remaining 85 patients, 77 underwent a PTG [median age=34.6 (23.7-46.2), American Society of Anesthesiologists score 1: 75%] mostly via a minimally invasive approach (51.9%). POM rate was 37.7% including 20.8% of severe POM, with age 40 years and above and low-volume centers as predictors ( P =0.030 and 0.038). After PTG, the cancer rate on specimen was 54.5% (n=42, all pT1a) of which 59.5% had no cancer detected on preoperative endoscopy (n=25). CONCLUSIONS: Among pCDH1vc, index cases carry a dismal prognosis. The risk of cancer among patients undergoing PTG remained high and unpredictable and has to be balanced with the morbidity and functional consequence of PTG.

C-reactive protein values after surgery for inflammatory bowel disease: is it still a good marker for intra-abdominal complication? A retrospective cohort study of 347 procedures : CRP after inflammatory bowel disease surgery.

PURPOSE: C-reactive protein (CRP) is a useful predictive test to early detect abdominal complication after colorectal surgery. Inflammatory bowel disease (IBD) is responsible for chronic inflammation and abnormal basal CRP that could influence the interest of its management after abdominal surgery. The aim of this study is to evaluate CRP as an indicator of postoperative complication in a specific IBD population. METHODS: Retrospective study of patients undergoing ileocolic resection or ileal pouch-anal anastomosis for IBD between 2012 and 2019. RESULTS: Ileocolic resection represents 242 patients and ileal pouch-anal anastomosis 105 patients. CRP was significantly higher at an early (105.2 ± 56.0 vs 128.1 ± 69.8; p = 0.008) and late stage (112.9 ± 72.8 vs 185.3 ± 111.5; p < 0.0001) for patients having an intra-abdominal complication. A BMI > 25 kg/m2 (p = 0.04) and an open surgical approach (p = 0.009) were associated with higher CRP levels in the first postoperative days (POD). In multivariate analysis, preoperative steroid use (p = 0.06), CRP at POD 3 > 100 mg/L (p = 0.003), and a rise between CRP values (p = 0.007) at 48 h were significantly associated with intra-abdominal complication. A CRP at POD 1 < 75 mg/L was associated with a lower rate of intra-abdominal complication (p = 0.01). A score dividing patients into 3 groups according to these values showed significant differences in intra-abdominal complication and anastomotic leakage rates. CONCLUSION: CRP is a useful predictive marker to detect abdominal complication after surgery in IBD population. Measurement of CRP can help to reduce hospitalization stay and orientate towards complementary examinations.

Redo-surgery after failed colorectal or coloanal anastomosis: Morbidity, mortality and factors predictive of success. A retrospective study of 200 patients.

AIM: In cases of anastomotic failure after colorectal (CRA) or coloanal anastomosis (CAA), revision of the anastomosis is an ambitious surgical option that can be proposed in order to maintain bowel continuity. Our aim was to assess postoperative morbidity, risk of failure and risk factor for failure in patients after CRA or CAA. METHODS: All consecutive patients who underwent redo-CRA/CAA in our institution between 2007-2018 were retrospectively included. The success of redo-CRA/CAA was defined by the restoration of bowel continuity 12 months after the surgery. RESULTS: Two hundred patients (114 male: 57%) were analyzed. The indication for redo-CRA/CAA was chronic pelvic infection in 74 patients (37%), recto-vaginal or urinary fistula in 59 patients (30%), anastomotic stenosis in 36 patients (18%) and redo anastomosis after previous anastomosis takedown in 31 patients (15%). Twenty-three percent of the patients developed a severe postoperative complication. Anastomotic leakage was diagnosed in 39 patients (20%). One-year-success of the redo-CRA/CAA was obtained in 80% of patients. In multivariate analysis, only obesity was associated with redo-CRA/CAA failure (p = 0.042). We elaborated a pre-operative predictive score of success using the four variables: male sex, age > 60 years, obesity and history of pelvic radiotherapy. The success of redo-CRA/CAA was 92%, 86%, 80% and 62% for a preoperative predictive score value of 0, 1, 2 and ≥3, respectively (p = 0.010). CONCLUSIONS: In case of failure of primary CRA/CAA, bowel continuity can be saved in 4 out of 5 patients by redo-CRA/CAA despite 23% suffering severe postoperative morbidity.

[Pathological complete response of a metastatic MisMatch Repair deficient/MicroSatellite Instable colon cancer after immunotherapy: A case report]. / Réponse histologique complète d'un cancer colique métastatique de phénotype MisMatch Repair déficient/MicroSatellite Instable après immunothérapie : à propos d'un cas.

Immunotherapies are part of the therapeutic strategy in many cancers and are indicated for metastatic colorectal adenocarcinoma with loss of expression of MisMatch Repair system proteins or with microsatelite instability (dMMR/MSI) in the United States. The rate of pathological response to immunotherapy remains poorly documented, but several cases of complete or major pathological response have recently been described. We decided to report the case of a complete pathological response to immunotherapy of a dMMR/MSI colorectal adenocarcinoma in a 74-year-old patient, initially inoperable due to duodenal invasion. Three months after the introduction of immunotherapy, the patient developed drug-induced colitis that contraindicated further treatment. Histological examination of the subtotal colectomy specimen revealed no residual tumour cells. The patterns of tumour regression were mainly represented by colloid regression, infarctoid-type necrosis and a resorptive inflammatory reaction. Although the operative indications for patients with metastatic dMMR/MSI colorectal cancer treated by immunotherapy are still very limited, the number of such specimens is expected to increase rapidly. The management of these specimens, as well as the possibility of a complete histological response, must be known by pathologists who play a key role in the pathophysiological knowledge of these lesions.

Surgical Management of Retrorectal Tumors: A French Multicentric Experience of 270 Consecutives Cases.

OBJECTIVE: To report the largest multicentric experience on surgical management of retrorectal tumors (RRT). BACKGROUND: Literature data on RRT is limited. There is no consensus concerning the best surgical approach for the management of RRT. METHODS: Patients operated for RRT in 18 academic French centers were retrospectively included (2000-2019). RESULTS: A total of 270 patients were included. Surgery was performed through abdominal (n = 72, 27%), bottom (n = 190, 70%), or combined approach (n = 8, 3%). Abdominal approach was laparoscopic in 53/72 (74%) and bottom approach was Kraske modified procedures in 169/190 (89%) patients. In laparoscopic abdominal group, tumors were more frequently symptomatic (37/53, 70% vs 88/169, 52%, P = 0.02), larger [mean diameter = 60.5 ± 24 (range, 13-107) vs 51 ± 26 (20-105) mm, P = 0.02] and located above S3 vertebra (n = 3/42, 7% vs 0%, P = 0.001) than those from Kraske modified group. Laparoscopy was associated with a higher risk of postoperative ileus (n = 4/53, 7.5% vs 0%, P = 0.002) and rectal fistula (n = 3/53, 6% vs 0%, P=0.01) but less wound abscess (n = 1/53, 2% vs 24/169, 14%, P = 0.02) than Kraske modified procedures. RRT was malignant in 8%. After a mean follow up of 27 ±39 (1-221) months, local recurrence was noted in 8% of the patients. After surgery, chronic pain was observed in 17% of the patients without significant difference between the 2 groups (15/74, 20% vs 3/30, 10%; P = 0.3). CONCLUSIONS: Both laparoscopic and Kraske modified approaches can be used for surgical treatment of RRT (according to their location and their size), with similar long-term results.

End Colostomy With or Without Mesh to Prevent a Parastomal Hernia (GRECCAR 7): A Prospective, Randomized, Double Blinded, Multicentre Trial.

OBJECTIVE: To evaluate whether systematic mesh implantation upon primary colostomy creation was effective to prevent PSH. SUMMARY OF BACKGROUND DATA: Previous randomized trials on prevention of PSH by mesh placement have shown contradictory results. METHODS: This was a prospective, randomized controlled trial in 18 hospitals in France on patients aged ≥18 receiving a first colostomy for an indication other than infection. Participants were randomized by blocks of random size, stratified by center in a 1:1 ratio to colostomy with or without a synthetic, lightweight monofilament mesh. Patients and outcome assessors were blinded to patient group. The primary endpoint was clinically diagnosed PSH rate at 24 months of the intention-to-treat population. This trial was registered at ClinicalTrials.gov, number NCT01380860. RESULTS: From November 2012 to October 2016, 200 patients were enrolled. Finally, 65 patients remained in the no mesh group (Group A) and 70 in the mesh group (Group B) at 24 months with the most common reason for drop-out being death (n = 41). At 24 months, PSH was clinically detected in 28 patients (28%) in Group A and 30 (31%) in Group B [P = 0.77, odds ratio = 1.15 95% confidence interval = (0.62;2.13)]. Stoma-related complications were reported in 32 Group A patients and 37 Group B patients, but no mesh infections. There were no deaths related to mesh insertion. CONCLUSION: We failed to show efficiency of a prophylactic mesh on PSH rate. Placement of a mesh in a retro-muscular position with a central incision to allow colon passage cannot be recommended to prevent PSH. Optimization of mesh location and reinforcement material should be performed.

Postoperative diagnostic revision for Crohn disease after subtotal colectomy for inflammatory bowel disease.

PURPOSE: Subtotal colectomy (STC) is performed for severe acute and refractory colitis. The diagnosis can be difficult even after the surgery when colectomy specimen has overlapping features of ulcerative colitis (UC) and Crohn's disease (CD). The aim of this study was to evaluate the rate of postoperative diagnostic revision to CD after surgery and determine predictor factors. METHODS: Retrospective study of 110 patients who underwent STC (2005-2018). RESULTS: Preoperative diagnosis comprised UC = 80 (73%), CD = 11 (10%), and unclassified colitis (IBDU = 19, 17%). Initial diagnosis of IBDU and UC was modified to CD in 6 patients (6%) after STC. The final diagnosis after the follow-up of 10 ± 6 years switched from CD for 8 patients (9%). The multivariate analysis showed that patients with a colitis evolving for less than 10 years and initial diagnosis of IBDU were the two independent factors associated with an increased risk of diagnosis change to CD (p = 0.03; p = 0.016). At the end of the follow-up, 15 patients (14%) had a definitive stoma. CONCLUSIONS: In patients with IBD, attention must be paid to determine the right restorative strategy to patients with an evolution of the disease less than 10 years or with IBDU who are more at risk to have a diagnosis change to CD after STC.

Laparoscopic rectal dissection preserves erectile function after ileal pouch-anal anastomosis: a two-centre study.

AIM: Few studies have been published on erectile function after ileal pouch-anal anastomosis (IPAA) and, unlike in women, male fertility after IPAA has never been assessed. The primary objective was to assess the impact of IPAA on erectile function. The secondary objective was to assess the impact of IPAA on male fertility. METHODS: All of the male patients who underwent IPAA in two university care centres between 2003 and 2017, aged 70 years or less at the time of operation, were included. Forty-eight per cent of the patients responded to the international index of erectile function, the Jorge-Wexner score and a fertility questionnaire. All demographic and perioperative data were prospectively collected. Fertility results were compared with those of a control group undergoing appendectomy, matched for age at the time of operation, desire for paternity and length of follow-up. RESULTS: One hundred and thirty-nine patients were included, among which 46 (33%) presented with erectile dysfunction and 14 (10%) with severe erectile dysfunction. Age older than 50 years (OR 0.27, 95% CI 0.12-0.62, P = 0.002) and rectal dissection performed by open surgery (OR 4.16, 95% CI 1.62-10.65, P = 0.003) were independent risk factors for erectile dysfunction. There was no infertility after IPAA compared with controls: indeed, 23 (16%) IPAA patients presented with pregnancy in their couple versus 27 (22%) controls (P = 0.29), whereas 36 (26%) IPAA patients and 34 (28%) controls (P = 0.80) expressed paternity desire. CONCLUSION: A total laparoscopic approach, including rectal dissection, should be preferred to preserve erectile function. Male fertility is not impaired after IPAA.

Reducing Patient Burden and Improving Data Quality With the New Cleveland Clinic Colorectal Cancer Quality of Life Questionnaire.

BACKGROUND: The Cleveland Clinic Colorectal Cancer Quality of Life Questionnaire was developed in response to the need for a new, fast, and comprehensive tool for evaluating quality of life in patients who have colorectal cancer. Available surveys such as the SF-12, SF-36, Functional Assessment of Cancer Therapy-Colorectal, and European Organization for Research and Treatment of Cancer are either too general to be informative or too lengthy to complete. OBJECTIVE: The aim was to validate the Cleveland Clinic Foundation Colorectal Quality of Life Questionnaire. DESIGN: Data were obtained as part of a prospective randomized controlled trial. SETTINGS: This was a worldwide multicenter study with 2 domestic and 5 international locations. PATIENTS: This study randomly assigned 190 patients between the ages of 18 and 80 undergoing surgery for low rectal cancer. Of those randomly assigned, 142 with partially complete surveys were analyzed for selection bias and acceptability, and 95 with complete surveys were analyzed for survey validity. INTERVENTIONS: Patients received either a J-pouch, side-to-end anastomosis, or straight anastomosis. MAIN OUTCOME MEASURE: The study evaluated survey validity measures such as standardized Cronbach α for internal consistency and Spearman correlation coefficients for construct validity, convergent validity, and responsiveness. Univariate analyses were used to assess discriminative validity. RESULTS: Sufficient acceptability, construct, and convergent validity and responsiveness were achieved. All scores showed great internal consistency (Cronbach α >0.8). Superior discriminative ability was demonstrated by significant differences (p < 0.05) in 2 of 7 scores between neoadjuvant treatment groups, and in 6 of 7 scores between complication groups, none of which were detected by the SF-12 or Functional Assessment of Cancer Therapy-Colorectal surveys. LIMITATIONS: Limitations included a small sample size, cultural differences, and failure to assess test-retest ability of the questionnaire. CONCLUSIONS: The Cleveland Clinic Colorectal Cancer Quality of Life Questionnaire is an efficient and reliable quality-of-life measure that better incorporates factors specific to colorectal cancer surgery.

REDUCIENDO LA CARGA AL PACIENTE Y MEJORANDO LA CALIDAD DE DATOS CON EL NUEVO CUESTIONARIO DE CALIDAD DE VIDA EN CÁNCER COLORRECTAL DE CLEVELAND CLINIC (CCF-CAQL): El cuestionario de calidad de vida en cáncer colorrectal de Cleveland Clinic se desarrolló en respuesta a la necesidad de una herramienta nueva, rápida e integral para evaluar la calidad de vida en pacientes con cáncer colorrectal. Los cuestionarios disponibles como SF-12, SF-36, FACT-C y EORTC son demasiado generales para ser informativas o demasiado largas para completar.El objetivo fue validar el cuestionario de calidad de vida colorrectal de la Cleveland Clinic Foundation.Los datos se obtuvieron como parte de un ensayo prospectivo aleatorizado y controlado.Este fue un estudio multicéntrico mundial con dos sedes nacionales y cinco internacionales.Este estudio aleatorizó a 190 pacientes entre las edades de 18 y 80 sometidos a cirugía por cáncer rectal bajo. De aquellos aleatorizados, 142 con encuestas parcialmente completas se analizaron para determinar el sesgo de selección y la aceptabilidad, y 95 con encuestas completas se analizaron para determinar la validez de la encuesta.Los pacientes recibieron un reservorio en J, anastomosis latero-terminal o anastomosis termino-terminal.El estudio evaluó medidas de validez de la encuesta, como el Alfa de Cronbach estandarizado para la consistencia interna y los coeficientes de correlación de Spearman para la validez de construcción, la validez de convergencia y la capacidad de respuesta. Se utilizaron análisis univariados para evaluar la validez discriminativa.Se obtuvo suficiente aceptabilidad, construcción, validez de convergencia, y capacidad de respuesta. Todos los puntajes mostraron una gran consistencia interna (alfa de Cronbach > 0.8). Una capacidad discriminativa superior fue demostrada por diferencias significativas (p < 0.05) en dos de siete puntajes entre grupos de tratamiento neoadyuvante, y en seis de siete puntajes entre grupos de complicaciones, ninguno de los cuales fue detectado por SF-12 o FACT-C.Las limitaciones incluyeron un tamaño de muestra pequeño, diferencias culturales y la falta de evaluación de la confiabilidad test-retest del cuestionario.El Cuestionario de Calidad de Vida en Cáncer Colorrectal de Cleveland Clinic es una medida de calidad de vida eficiente y confiable que incorpora mejor factores específicos asociados a la cirugía de cáncer colorrectal.

Can a Local Drainage Salvage a Failed Colorectal or Coloanal Anastomosis? A Prospective Cohort of 54 Patients.

BACKGROUND: Local drainages can be used to manage leakage in select patients without peritonitis. OBJECTIVE: The aim of this study was to evaluate the efficacy of drainage procedures in maintaining a primary low anastomosis after anastomotic leakage. DESIGN: A retrospective observational study was performed on a prospectively maintained database. SETTINGS: The study was performed between 2014 and 2017 in a tertiary referral center. PATIENTS: Patients undergoing rectal resections with either a colorectal or coloanal anastomosis with diverting stoma were identified. Anastomotic leakages requiring a radiological or transanal drainage without peritonitis were included. MAIN OUTCOME MEASURES: The primary outcome was the maintenance of the primary anastomosis after local drainage of an anastomotic leakage and stoma reversal. RESULTS: A low anastomosis for rectal cancer with diverting stoma was performed in 326 patients. A total of 77 anastomotic leakages (24%) occurred, of which, 6 (8%) required abdominal surgery, 17 (22%) were treated conservatively (medical management), and 54 (70%) were managed by drainage. Surgical transanal drainage was performed in 21 patients (39%), with radiologic drainage procedures performed in 33 patients (61%). The median interval between surgery and drainage was 13 days (range, 9-21 d). Five patients (9%) required emergency abdominal surgery. Twenty-seven patients (50%) did not require any additional intervention after drainage procedure, whereas 21 patients (39%) underwent redo anastomotic surgery. Forty-three patients (80%) had no stoma at the end of follow-up. Failure to maintain the primary anastomosis after local drainage was associated with increased age (p = 0.04), a pelvic per-operative drainage (p = 0.05), a drainage duration >10 days (p = 0.002), the time between surgery and drainage >15 days (p = 0.03), a side-to-end or J-pouch anastomosis (p = 0.04), and surgical transanal drainage (p = 0.03). LIMITATIONS: The small sample size of the study was the main limitation. CONCLUSIONS: Local drainage procedures maintained primary anastomosis in 50% of cases after an anastomotic leakage.

UNA COHORTE PROSPECTIVO DE 54 PACIENTES: Los drenajes locales se pueden utilizar para controlar las fugas en pacientes seleccionados sin peritonitis.El objetivo de este estudio fue evaluar la eficacia de los procedimientos de drenaje, para mantener una anastomosis primaria baja, después de una fuga anastomótica.Se realizó un estudio observacional retrospectivo en una base de datos mantenida prospectivamente.El estudio se realizó entre 2014-2017, en un centro de referencia terciaria.Se identificaron pacientes sometidos a resecciones rectales con anastomosis colorrectal o coloanal y estoma de derivación. Se incluyeron fugas anastomóticas sin peritonitis, que requirieron drenaje radiológico o transanal.El resultado primario fue el mantenimiento de la anastomosis primaria, después del drenaje local de una fuga anastomótica y la reversión del estoma.Se realizó una anastomosis baja para cáncer rectal con estoma derivativo en 326 pacientes. Se produjeron 77 (24%) fugas anastomóticas, de las cuales 6 (8%) requirieron cirugía abdominal, 17 (22%) fueron tratadas de forma conservadora (tratamiento médico) y 54 (70%) fueron manejadas por drenaje. Se realizó drenaje transanal en 21 pacientes (39%) y procedimientos de drenaje radiológico en 33 pacientes (61%). La mediana del intervalo entre la cirugía y el drenaje fue de 13 días [9-21]. 5 (9%) pacientes requirieron cirugía abdominal de emergencia. Veintisiete (50%) pacientes no requirieron ninguna intervención adicional después del procedimiento de drenaje, mientras que 21 pacientes (39%) se sometieron a una reparación quirúrgica anastomótica. 43 pacientes (80%) no tuvieron estoma al final del seguimiento. El fracaso para mantener la anastomosis primaria después del drenaje local, se asoció con un aumento de la edad (p = 0.04), un drenaje pélvico preoperatorio (p = 0.05), una duración del drenaje >10 días (p = 0.002), el tiempo entre la cirugía y el drenaje >15 días (p = 0.03), anastomosis termino lateral o bolsa en J (p = 0.04) y drenaje quirúrgico transanal (p = 0.03).El pequeño tamaño de la muestra del estudio fue la principal limitación.Después de la fuga anastomótica, los procedimientos del drenaje local conservaron la anastomosis primaria en el 50% de los casos.

Emergency Surgery in Acute Diverticulitis: A Systematic Review.

BACKGROUND: Acute diverticulitis is a common disease with public health significance. Many studies with a high level of evidence have been published recently on the surgical management of acute diverticulitis. OBJECTIVE: The aim of this systematic review was to define the accurate surgical management of acute diverticulitis. DATA SOURCES: Medline, Embase, and the Cochrane Library were sources used. STUDY SELECTION: One reviewer conducted a systematic study with combinations of key words for the disease and the surgical procedure. Additional studies were searched in the reference lists of all included articles. The results of the systematic review were submitted to a working group composed of 13 practitioners. All of the conclusions were obtained by full consensus and validated by an external committee. INTERVENTIONS: The interventions assessed were laparoscopic peritoneal lavage, primary resection with anastomosis with or without ileostomy, and the Hartmann procedure, with either a laparoscopic or an open approach. MAIN OUTCOME MEASURES: Morbidity, mortality, long-term stoma rates, and quality of life were measured. RESULTS: Seventy-one articles were included. Five guidelines were retrieved, along with 4 meta-analyses, 14 systematic reviews, and 5 randomized controlled trials that generated 8 publications, all with a low risk of bias, except for blinding. Laparoscopic peritoneal lavage showed concerning results of deep abscesses and unplanned reoperations. Studies on Hinchey III/IV diverticulitis showed similar morbidity and mortality. A reduced length of stay with Hartmann procedure compared with primary resection with anastomosis was reported in the short term, and in the long term, more definite stoma along with poorer quality of life was reported with Hartmann procedure. No high-quality data were found to support the laparoscopic approach. LIMITATIONS: Trials specifically assessing Hinchey IV diverticulitis have not yet been completed. CONCLUSIONS: High-quality studies showed that laparoscopic peritoneal lavage was associated with an increased morbidity and that Hartmann procedure was associated with poorer long-term outcomes than primary resection with anastomosis with ileostomy, but Hartmann procedure is still acceptable, especially in high-risk patients.
