Risk factors for emergency surgery for diverticulitis: A retrospective multicentric French study at 41 hospitals.

BACKGROUND: The observed increase in the incidence of complicated diverticulitis may lead to the performance of more emergency surgeries. This study aimed to assess the rate and risk factors of emergency surgery for sigmoid diverticulitis. METHOD: The primary outcomes were the rate of emergency surgery for sigmoid diverticulitis and its associated risk factors. The urgent or elective nature of the surgical intervention was provided by the surgeon and in accordance with the indication for surgical treatment. A mixed logistic regression with a random intercept after multiple imputations by the chained equation was performed to consider the influence of missing data on the results. RESULTS: Between 2010 and 2021, 6,867 patients underwent surgery for sigmoid diverticulitis in the participating centers, of which one-third (n = 2317) were emergency cases. In multivariate regression analysis with multiple imputation by chained equation, increasing age, body mass index <18.5 kg/m2, neurologic and pulmonary comorbidities, use of anticoagulant drugs, immunocompromised status, and first attack of sigmoid diverticulitis were independent risk factors for emergency surgery. The likelihood of emergency surgery was significantly more frequent after national guidelines, which were implemented in 2017, only in patients with a history of sigmoid diverticulitis attacks. CONCLUSION: The present study highlights a high rate (33%) of emergency surgery for sigmoid diverticulitis in France, which was significantly associated with patient features and the first attack of diverticulitis.

Adenocarcinoma-Induced Sigmoid Colon Intussusception and Postoperative Parastomal Evisceration in an Elderly Patient: A Case Report and Literature Review.

Intussusception in adults is less frequent than in children, and it is less commonly seen in the colon than in the intestines. This may be explained by the fixation of the colon to the retroperitoneum. We herein describe a case of sigmoid colon intussusception caused by a sigmoid colon adenocarcinoma. An 81-year-old man presented with abdominal pain and signs and symptoms of gastrointestinal obstruction. CT revealed a "target sign" with a mass in the sigmoid colon. We diagnosed the patient with colonic obstruction secondary to intussusception of the sigmoid colon and performed an emergency transverse colostomy. On the first postoperative day, the patient had a parastomal evisceration. Oncologic resection of the sigmoid colon without reduction of the intussusception was performed. The tumor was pathologically diagnosed as well-differentiated adenocarcinoma and classified as pT3N0. The patient was discharged on the ninth postoperative day with an uneventful postoperative course. The surveillance was validated for this patient.

Impact of the first wave of COVID-19 epidemy on the surgical management of sigmoid diverticular disease in France: National French retrospective study.

OBJECTIVE: To analyze the surgical management of sigmoid diverticular disease (SDD) before, during, and after the first containment rules (CR) for the first wave of COVID-19. METHODS: From the French Surgical Association multicenter series, this study included all patients operated on between January 2018 and September 2021. Three groups were compared: A (before CR period: 01/01/18-03/16/20), B (CR period: 03/17/20-05/03/20), and C (post CR period: 05/04/20-09/30/21). RESULTS: A total of 1965 patients (A n = 1517, B n = 52, C n = 396) were included. The A group had significantly more previous SDD compared to the two other groups (p = 0.007), especially complicated (p = 0.0004). The rate of peritonitis was significantly higher in the B (46.1%) and C (38.4%) groups compared to the A group (31.7%) (p = 0.034 and p = 0.014). As regards surgical treatment, Hartmann's procedure was more often performed in the B group (44.2%, vs A 25.5% and C 26.8%, p = 0.01). Mortality at 90 days was significantly higher in the B group (9.6%, vs A 4% and C 6.3%, p = 0.034). This difference was also significant between the A and B groups (p = 0.048), as well as between the A and C groups (p = 0.05). There was no significant difference between the three groups in terms of postoperative morbidity. CONCLUSION: This study shows that the management of SDD was impacted by COVID-19 at CR, but also after and until September 2021, both on the initial clinical presentation and on postoperative mortality.

Combination of serum and peritoneal 1.3-beta-D-glucan can rule out intra-abdominal candidiasis in surgical critically ill patients: a multicenter prospective study.

BACKGROUND: Intra-abdominal candidiasis (IAC) is difficult to predict in critically ill patients with intra-abdominal infection, leading to the overuse of antifungal treatments. Serum and peritoneal 1.3-beta-D-glucan (sBDG and pBDG) have been proposed to confirm or invalidate the diagnosis of IAC, but clinical studies have reported inconsistent results, notably because of heterogeneous populations with a low IAC prevalence. This study aimed to identify a high-risk IAC population and evaluate pBDG and sBDG in diagnosing IAC. METHODS: This prospective multicenter noninterventional French study included consecutive critically ill patients undergoing abdominal surgery for abdominal sepsis. The primary objective was to establish the IAC prevalence. The secondary objective was to explore whether sBDG and pBDG could be used to diagnose IAC. Wako® beta-glucan test (WT, Fujifilm Wako Chemicals Europe, Neuss, Germany) was used for pBDG measurements. WT and Fungitell® beta-D-glucan assay (FA, Associate of Cape Cod, East Falmouth, USA) were used for sBDG measurements. RESULTS: Between 1 January 2020 and 31 December 2022, 199 patients were included. Patients were predominantly male (63%), with a median age of 66 [54-72] years. The IAC prevalence was 44% (87/199). The main IAC type was secondary peritonitis. Septic shock occurred in 63% of cases. After multivariate analysis, a nosocomial origin was associated with more IAC cases (P = 0.0399). The median pBDG level was significantly elevated in IAC (448 [107.5-1578.0] pg/ml) compared to non-IAC patients (133 [16.0-831.0] pg/ml), P = 0.0021. For a pBDG threshold of 45 pg/ml, the negative predictive value in assessing IAC was 82.3%. The median sBDG level with WT (n = 42) at day 1 was higher in IAC (5 [3.0-9.0] pg/ml) than in non-IAC patients (3 [3.0-3.0] pg/ml), P = 0.012. Similarly, median sBDG level with FA (n = 140) at day 1 was higher in IAC (104 [38.0-211.0] pg/ml) than in non-IAC patients (50 [23.0-141.0] pg/ml), P = 0.009. Combining a peritonitis score < 3, sBDG < 3.3 pg/ml (WT) and pBDG < 45 pg/ml (WT) yielded a negative predictive value of 100%. CONCLUSION: In critically ill patients with intra-abdominal infection requiring surgery, the IAC prevalence was 44%. Combining low sBDG and pBDG with a low peritonitis score effectively excluded IAC and could limit unnecessary antifungal agent exposure. TRIAL REGISTRATION: The study was registered with ClinicalTrials.gov (ID number 03997929, first registered on June 24, 2019).

Reappraisal of intra-abdominal candidiasis: insights from peritoneal fluid analysis.

BACKGROUND: The understanding of high mortality associated with intra-abdominal candidiasis (IAC) remains limited. While Candida is considered a harmless colonizer in the digestive tract, its role as a true pathogen in IAC is still debated. Evidence regarding Candida virulence in the human peritoneal fluid are lacking. We hypothesized that during IAC, Candida albicans develops virulence factors to survive to new environmental conditions. The objective of this observational exploratory monocentric study is to investigate the influence of peritoneal fluid (PF) on the expression of C. albicans virulence using a multimodal approach. MATERIALS AND METHODS: A standardized inoculum of a C. albicans (3.106 UFC/mL) reference strain (SC5314) was introduced in vitro into various PF samples obtained from critically ill patients with intra-abdominal infection. Ascitic fluids (AFs) and Sabouraud medium (SBD) were used as control groups. Optical microscopy and conventional culture techniques were employed to assess the morphological changes and growth of C. albicans. Reverse transcriptase qPCR was utilized to quantify the expression levels of five virulence genes. The metabolic production of C. albicans was measured using the calScreener™ technology. RESULTS: A total of 26 PF samples from patients with secondary peritonitis were included in the study. Critically ill patients were mostly male (73%) with a median age of 58 years admitted for urgent surgery (78%). Peritonitis was mostly hospital-acquired (81%), including 13 post-operative peritonitis (50%). The infected PF samples predominantly exhibited polymicrobial composition. The findings revealed substantial variability in C. albicans growth and morphological changes in the PF compared to ascitic fluid. Virulence gene expression and metabolic production were dependent on the specific PF sample and the presence of bacterial coinfection. CONCLUSIONS: This study provides evidence of C. albicans virulence expression in the peritoneal fluid. The observed variability in virulence expression suggests that it is influenced by the composition of PF and the presence of bacterial coinfection. These findings contribute to a better understanding of the complex dynamics of intra-abdominal candidiasis and advocate for personalized approach for IAC patients.

Stemming the tide with ileocecal Crohn's disease: when is pharmacotherapy enough?

INTRODUCTION: Crohn's disease (CD) mostly affects the terminal ileum and ileocecal region and up to 80% of patients end up requiring surgery. Previously reserved for complicated or refractory forms, surgery is now considered as an alternative to medical treatment in localized ileocecal disease. AREAS COVERED: This review examines factors associated with response to medical treatment and those associated with the need for surgery in ileocecal CD to identify the patients' profile for whom pharmacotherapy might be enough. Factors associated with the recurrence and the postoperative complications are also reviewed to help the clinician identify patients for whom medical therapy might be preferred. EXPERT'S OPINION: LIR!C study long-term follow-up data show that 38% of infliximab-treated patients were still treated with infliximab at the end of their follow-up, while 14% had switched to another biologic or had received immunomodulator or corticosteroid and 48% had CD-related surgery. Only the combination with an immunomodulator was associated with a greater likelihood of continuing infliximab. Patients with ileocecal CD for whom pharmacotherapy might be sufficient are probably those with no risk factors for CD-related surgery.In addition, patients with high risk of recurrence or of post-operative complications may benefit more from medical treatment than from surgery.

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.

Iatrogenic ureteral injury during colorectal surgery has a significant impact on patient outcomes: a French multicentric retrospective cohort study.

AIM: The long-term urological sequelae after iatrogenic ureteral injury (IUI) during colorectal surgery are not clearly known. The aims of this work were to report the incidence of IUI and to analyse the long-term consequences of urological late complications and their impact on oncological results of IUI occurring during colorectal surgery through a French multicentric experience (GRECCAR group). METHOD: All the patients who presented with IUI during colorectal surgery between 2010 and 2019 were retrospectively included. Patients with ureteral involvement needing en bloc resection, delayed ureteral stricture or noncolorectal surgery were not considered. RESULTS: A total of 202 patients (93 men, mean age 63 ± 14 years) were identified in 29 centres, corresponding to 0.32% of colorectal surgeries (n = 63 562). Index colorectal surgery was mainly oncological (n = 130, 64%). IUI was diagnosed postoperatively in 112 patients (55%) after a mean delay of 11 ± 9 days. Intraoperative diagnosis of IUI was significantly associated with shorter length of stay (21 ± 22 days vs. 34 ± 22 days, p < 0.0001), lower rates of postoperative hydronephrosis (2% vs. 10%, p = 0.04), anastomotic complication (7% vs. 22.5%, p = 0.002) and thromboembolic event (0% vs. 6%, p = 0.02) than postoperative diagnosis of IUI. Delayed chemotherapy because of IUI was reported in 27% of patients. At the end of the follow-up [3 ± 2.6 years (1 month-13 years)], 72 patients presented with urological sequalae (36%). Six patients (3%) required a nephrectomy. CONCLUSION: IUI during colorectal surgery has few consequences for the patients if recognized early. Long-term urological sequelae can occur in a third of patients. IUI may affect oncological outcomes in colorectal surgery by delaying adjuvant chemotherapy, especially when the ureteral injury is not diagnosed peroperatively.

Is pancreatic head surgery safe in the elderly?

BACKGROUND: During the last century, life expectancy has doubled. As a result, senior patients with cancer are more frequently referred for possible surgery. Pancreatic surgery is a complex surgery associated with significant postoperative morbidity. Surgical decision-making in the elderly population can be difficult because outcomes in the elderly are poorly defined. Our objective is to characterize differences in mortality and morbidity for pancreatic surgery in the elderly population. METHODS: A retrospective review of all patients undergoing pancreatic head surgery in our tertiary referral center from 2015 to 2021 was conducted. Analysis was performed for the entire cohort, classifying patients into three age groups: <70 years, 70-79 years, and ≥80 years. Data from these three groups were compared, including comorbidity, oncologic outcomes and postoperative complications. RESULTS: A total of 326 patients underwent pancreatic head resection. The 90-day mortality increased from 2.9% to 5.3% to 15.4% with increasing age (p = 0,015). There were no differences among the three groups in terms of postoperative morbidity. There was no difference in disease-free survival (DFS), but overall survival was better in patients under 70 years (p = 0,046). CONCLUSION: Compared to younger patients, patients over 80 years old have a higher risk of mortality despite similar postoperative morbidity.

Deep Dive Into MicroRNAs in Inflammatory Bowel Disease.

Inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, is thought to develop in genetically predisposed individuals as a consequence of complex interactions between dysregulated inflammatory stimuli, immunological responses, and environmental factors. The pathogenesis of IBD has yet to be fully understood. The global increase in the incidence of IBD suggests a gap in the current understanding of the disease. The development of a new diagnostic tool for inflammatory bowel disease that is both less invasive and more cost-effective would allow for better management of this condition. MicroRNAs (miRNAs) are a class of noncoding RNAs with important roles as posttranscriptional regulators of gene expression, which has led to new insights into understanding IBD. Using techniques such as microarrays and real-time polymerase chain reactions, researchers have investigated the patterns in which patients with Crohn's disease and ulcerative colitis show alterations in the expression of miRNA in tissue, blood, and feces. These miRNAs are found to be differentially expressed in IBD and implicated in its pathogenesis through alterations in autophagy, intestinal barrier, and immune homeostasis. In this review, we discuss the miRNA expression profiles associated with IBD in tissue, peripheral blood, and feces and provide an overview of the miRNA mechanisms involved in IBD.

We review the published studies on microRNA (miRNA) expression in inflammatory bowel disease, including miRNAs extracted from blood, tissue, and stool samples. We discuss the main mechanisms of miRNA involvement in inflammatory bowel disease and their potential use as biomarkers.

Preoperative Magnetic Resonance Enterography to Predict Pathological Specimen Length in Crohn's Disease.

BACKGROUND: The European Crohn's and Colitis Organization guidelines have highlighted the importance of the preoperative evaluation of the affected segment length in patients with ileocolic Crohn's disease to determine the best surgical approach. OBJECTIVE: This study aimed to evaluate the accuracy of preoperative magnetic resonance enterography in assessing the length of the affected segment in patients with ileocolic Crohn's disease. DESIGN: This observational study was conducted with a prospectively maintained database and retrospective analysis. SETTINGS: This study was conducted in a tertiary center. PATIENTS: This study included consecutive patients undergoing ileocolic resection for Crohn's disease between August 2014 and June 2020. All patients underwent a preoperative magnetic resonance enterography. MAIN OUTCOME MEASURES: The correlation between the length measured on magnetic resonance enterography and pathological examination was evaluated. RESULTS: A total of 96 patients were included. The median time between magnetic resonance enterography and surgery was 65.5 (3-331) days. The length of the affected segment on magnetic resonance enterography was correlated with the length assessed on pathological evaluation ( R = 0.48, p < 0.001). No correlation was found between the 2 measurements when imaging was performed >6 months before surgery ( R = 0.14, p = 0.62). The presence of an abscess underestimated the length affected by Crohn's disease on imaging compared to pathology, whereas the presence of a fistula was associated with magnetic resonance enterography overestimation of the length of the affected segment. LIMITATIONS: Limitations included single-center study and retrospective analysis. CONCLUSION: In Crohn's disease, preoperative magnetic resonance enterography is a highly reliable tool for predicting the length of the affected segment compared to pathology examination in the absence of an abscess or fistula.

ENTEROGRAFA POR RESONANCIA MAGNTICA PREOPERATORIA PARA PREDECIR LA LONGITUD DE MUESTRAS PATOLGICAS EN LA ENFERMEDAD DE CROHN: ANTECEDENTES:Las guías de la Organización Europea de Crohn y Colitis han resaltado la importancia de la evaluación preoperatoria de la longitud del segmento afectado para determinar el mejor abordaje quirúrgico.OBJETIVO:Evaluamos la precisión de la enterografía por resonancia magnética preoperatoria para evaluar la longitud del segmento afectado en pacientes con enfermedad de Crohn ileocólica.DISEÑO:Realizamos un estudio observacional con una base de datos mantenida prospectivamente y un análisis retrospectivo.CONFIGURACIÓN:Este estudio se realizó en un centro terciario.PACIENTES:Se incluyeron pacientes consecutivos sometidos a resección ileocólica por enfermedad de Crohn entre Agosto de 2014 y Junio de 2020. A todos los pacientes se les realizó una enterografía por resonancia magnética preoperatoria.PRINCIPALES MEDIDAS DE RESULTADO:Se evaluó la correlación entre la longitud medida en la enterografía por resonancia magnética y el examen patológico.RESULTADOS:Se incluyeron un total de 96 pacientes. El tiempo mediano entre la enterografía por resonancia magnética y la cirugía fue de 65,5 (3-331) días. La longitud del segmento afectado en la enterografía por resonancia magnética se correlacionó con la longitud evaluada en la evaluación patológica ( R = 0,48, p < 0,001). No hubo correlación entre las 2 mediciones cuando las imágenes se realizaron más de 6 meses antes de la cirugía ( R = 0,14, p = 0,62). La presencia de un absceso subestimó la longitud afectada por la enfermedad de Crohn en las imágenes en comparación con la patología, mientras que la presencia de una fístula se asoció con una sobrestimación de la longitud del segmento afectado por enterografía por resonancia magnética.LIMITACIONES:Las limitaciones incluyeron un estudio de un solo centro y un análisis retrospectivo.CONCLUSIÓNES:En la enfermedad de Crohn, la enterografía por resonancia magnética preoperatoria es una herramienta altamente confiable para predecir la longitud del segmento afectado en comparación con el examen de patología, en ausencia de absceso o fístula.

Transcriptomic FHITlow/pHER2high signature as a predictive factor of outcome and immunotherapy response in non-small cell lung cancer.

Introduction: In recent decades, the development of immunotherapy and targeted therapies has considerably improved the outcome of non-small cell lung cancer (NSCLC) patients. Despite these impressive clinical benefits, new biomarkers are needed for an accurate stratification of NSCLC patients and a more personalized management. We recently showed that the tumor suppressor fragile histidine triad (FHIT), frequently lost in NSCLC, controls HER2 receptor activity in lung tumor cells and that tumor cells from NSCLC patients harboring a FHITlow/pHER2high phenotype are sensitive to anti-HER2 drugs. Here, we sought to identify the transcriptomic signature of this phenotype and evaluate its clinical significance. Materials and methods: We performed RNA sequencing analysis on tumor cells isolated from NSCLC (n=12) according to FHIT/pHER2 status and a functional analysis of differentially regulated genes. We also investigated the FHITlow/pHER2high signature in The Cancer Genome Atlas (TCGA) lung adenocarcinoma (LUAD) (n=489) and lung squamous cell carcinoma (LUSC) (n=493) cohorts and used the tumor immune dysfunction and exclusion (TIDE) model to test the ability of this signature to predict response to immune checkpoint inhibitors (ICI). Results: We showed that up-regulated genes in FHITlow/pHER2high tumors were associated with cell proliferation, metabolism and metastasis, whereas down-regulated genes were related to immune response. The FHITlow/pHER2high signature was associated with the higher size of tumors, lymph node involvement, and late TNM stages in LUAD and LUSC cohorts. It was identified as an independent predictor of overall survival (OS) in LUAD cohort. FHITlow/pHER2high tumors were also predictive of poor response to ICI in both LUAD and LUSC cohorts. Conclusion: These data suggest that ICI might not be a relevant option for NSCLC patients with FHITlow/pHER2high tumors and that anti-HER2 targeted therapy could be a good therapeutic alternative for this molecular subclass with poorer prognosis.

Whole-Exome Sequencing of Bronchial Epithelial Cells Reveals a Genetic Print of Airway Remodelling in COPD.

The remodelling of the airways is a hallmark of chronic obstructive pulmonary disease, but it is highly heterogeneous and erratically distributed in the airways. To assess the genetic print of remodelling in chronic obstructive pulmonary disease (COPD), we performed a comparative whole-exome sequencing analysis on microdissected bronchial epithelia. Lung resections from four non-COPD and three COPD subjects (ex-smokers and current smokers) were formalin-fixed paraffin-embedded (FFPE). Non-remodelled and remodelled bronchial epithelia were isolated by laser microdissection. Genomic DNA was captured and sequenced. The comparative quantitative analysis identified a list of 109 genes as having variants in remodelled epithelia and 160 genes as having copy number alterations in remodelled epithelia, mainly in COPD patients. The functional analysis highlighted cilia-associated processes. Therefore, bronchial-remodelled epithelia appeared genetically more altered than non-remodelled epithelia. Characterizing the unique molecular print of airway remodelling in respiratory diseases may help uncover additional factors contributing to epithelial dysfunctions, ultimately providing additional targetable proteins to correct epithelial remodelling and improve lung function.

Is Hartmann's Pouch an Option in the Management of Acute Severe Ulcerative Colitis?

BACKGROUND: The surgical management of remnant rectosigmoid after subtotal colectomy with end ileostomy for acute severe ulcerative colitis remains controversial with respect to the need to perform sigmoidostomy or Hartmann's pouch. The aim of this retrospective study was to investigate whether Hartmann's pouch may be a safe option. METHODS: Thirty-eight Hartmann's pouches were performed between January 2003 and December 2015. We looked at morbidity (with a focus on the occurrence of pelvic sepsis and leakage of the rectal stump) and the rate of restored intestinal continuity. RESULTS: Nineteen patients had surgical complications. Seven had an intra-abdominal collection, only one of which was in the pelvis, and the patient had to be reoperated. Only one patient had a reopening of the rectal stump, which was revealed by rectal bleeding. Twenty-six patients (68.4%) underwent further proctectomy with ileal J-pouch anal anastomosis with no difficulty in localizing or mobilizing the rectal stump and no major surgical complications. CONCLUSIONS: Hartmann's pouch may be considered in patients with acute severe ulcerative colitis, with low rates of morbidity and pelvic sepsis. The restoration of intestinal continuity is possible after this procedure without any special difficulty.

Weight change after colectomy for ulcerative colitis.

BACKGROUND AND OBJECTIVE: Weight change after colectomy for ulcerative colitis is unknown. The main objective of this study was to describe weight change during surgical management of ulcerative colitis. METHODS: All patients, underwent a subtotal colectomy, then a proctectomy with J ileal pouch anal anastomosis protected by an ileostomy, and finally an ileostomy closure in the context of ulcerative colitis at the Nancy University Hospital from May 2014 to October 2020, were included. For each patient, his healthy weight, preoperative weight and postoperative weight were recorded for each step of surgery. RESULTS: Twenty-six patients were included. The median body mass index of healthy weight was 23.3 kg/m2. Before subtotal colectomy, the median body mass index decreased to 21.3 kg/m2, a reduction of 8.5%. One month after subtotal colectomy, the median body mass index was at its lowest level of 20.8 kg/m2, which represented a 10.7% decrease from the healthy weight. Thereafter a significant increase in body mass index was observed before the proctectomy, reaching the threshold of 22.8 kg/m2, an increase of 8.7% from the lowest level. After the last surgical time, which corresponds to the ileostomy closure, the body mass index was 23.2 kg/m2, this threshold was comparable to the healthy weight body mass index. CONCLUSION: Our study showed for the first time that after colectomy for ulcerative colitis, patients regained their healthy weight, which constitutes a reassuring message for patients before surgery.

Impact of preoperative enteral nutritional support on postoperative outcome in patients with Crohn's disease complicated by malnutrition: Results of a subgroup analysis of the nationwide cohort registry from the GETAID Chirurgie group.

AIM: Postoperative morbidity is high in patients operated on for Crohn's disease (CD) complicated by malnutrition. This study aimed to evaluate the impact of preoperative enteral nutritional support (PENS) on postoperative outcome in patients with CD complicated by malnutrition included in a prospective nationwide cohort. METHOD: Malnutrition was defined as body mass index <18 kg/m2 and/or albuminaemia <30 g/L and/or weight loss >10%. Failure of PENS was defined as the requirement for additional preoperative parenteral nutrition to PENS. Univariate analysis of the risk factors for PENS failure was performed. Propensity score matching (PSM) was used to compare the outcomes between 'upfront surgery' and 'PENS' groups. The primary endpoint was the rate of intra-abdominal septic morbidity and/or temporary defunctioning stoma. RESULTS: Among 592 patients included, 149 were selected. In the intention-to-treat population including 20 (13.4%) patients with PENS failure after PSM, 78 'upfront surgery' and 71 'PENS'-matched patients were compared, with no significant difference in the primary endpoint. Perforating CD and preoperative intra-abdominal fistula were associated with PENS failure [37.5 vs 16.1% (P = 0.047) and 41.2% vs 16.2% (P = 0.020), respectively]. After exclusion of these 20 patients, PSM was used to compare 45 'upfront surgery' and 51 'PENS'-matched patients, with a significantly decreased rate of intra-abdominal septic complications and/or temporary defunctioning stoma in the PENS group (19.6 vs 42.2%, P = 0.016). CONCLUSION: Preoperative enteral nutritional support is associated with a trend but no conclusive evidence of a reduction in intra-abdominal septic complications and/or requirement for defunctioning stoma. Patients with perforating CD complicated with malnutrition are at risk of PENS failure.

Risk of Late Postoperative Recurrence of Crohn's Disease in Patients in Endoscopic Remission After Ileocecal Resection, Over 10 Years at Multiple Centers.

BACKGROUND & AIMS: The risk of recurrence of Crohn's disease (CD) from 1 to 10 years after surgery despite initial endoscopic remission (late post-operative recurrence) is not clear. METHODS: We performed a retrospective study, at 3 inflammatory bowel disease (IBD) centers in France and Belgium, of all patients with CD (n = 86) undergoing an ileocecal resection with curative intent from 2006 through 2016 who did not have endoscopic evidence for recurrence (Rutgeerts score less than i2) at their baseline assessment. Postoperative recurrence after baseline endoscopy was defined as a composite endpoint of at least 1 of the following: clinical recurrence, IBD-related hospitalization, occurrence of bowel damage, need for endoscopic balloon dilatation of the anastomosis, and need to repeat the surgery. Risk of mucosal disease progression was studied as a secondary outcome. RESULTS: The median time between surgery and baseline endoscopy was 7 months (IQR, 5.7-9.5 months); 40 patients (46.5%) received medical prophylaxis in this period. The median follow-up time was 3.5 years (IQR, 1.6-5.3 years). Thirty-five patients (40.7%) had a late post-operative recurrence of CD, with a median time to disease recurrence after baseline endoscopy of 14.2 months (IQR, 6.3-26.1 months). Recurrence status did not differ significantly between patients with Rutgeerts scores of i0 (20/55) or i1 (15/31) at baseline (P = .28) and was independent of medical prophylaxis (16/40 with prophylactic therapy vs 19/46 without prophylactic therapy; P = .90). Mucosal disease progressed in 29 of the 71 patients (40.8%) with available data. We did not identify risk factors for late post-operative recurrence of CD or mucosal disease progression. CONCLUSIONS: Among patients with CD treated by ileocecal resection, 40% of patients had a late recurrence, despite initial endoscopic remission, after a median follow-up time of 3.5 years. Tight monitoring of these patients is recommended beyond 18 months.

Predictors for short bowel syndrome in Crohn's disease.

BACKGROUND AND AIM: Patients with Crohn's disease (CD) are at risk for short bowel syndrome (SBS). We investigated independent predictors for SBS in these patients to allow the development of preventive strategies. METHODS: All adult patients seen at the Nancy University hospital for CD or SBS between 2012 and 2019 were eligible for inclusion in this case-control study. Each CD patient with SBS was matched to 9 controls. RESULTS: 410 CD patients were included (369 without SBS and 41 with SBS). Subjects with SBS underwent significantly more bowel resections (median value of 3 vs 1, p<0.0001) and median time before the first surgery was not different than controls (6 vs 4 years, p=0.59). A higher need for parenteral support was found in end-jejunostomy SBS than in jejunocolic and jejunoileal SBS (70.6% vs 25% and 0%, p=0.0031). Montreal B1 behavior (OR 0.02, CI 95% 0-0.08) and budesonide treated-patients (OR=0.03, CI 95% 0.003-0.2) were at lower risk of SBS, while IV steroid treated-patients were at higher risk (OR=8.5, CI 95% 3.0-24.9). CONCLUSION: Montreal B1 behavior, IV steroids and budesonide use are influencing predictors for this complication. These predictors should be assessed in daily clinical practice to prevent SBS occurrence.

Surgery for Crohn's disease during pregnancy: A nationwide survey.

BACKGROUND AND AIMS: Crohn's disease (CD) frequently affects young women and may require surgery during pregnancy. Data regarding operation for CD in expectant mothers are scare. MATERIALS AND METHODS: This was a retrospective nationwide survey from the GETAID Chirurgie. Any woman with CD undergoing surgery during pregnancy was eligible. RESULTS: A total of 15 cases were collected between 1992 and 2015. Most operations were performed due to penetrating or stricturing complications. Mean gestational age at delivery was 34 weeks, with a mean birth weight of 2507 g. Maternal post-operative complications occurred in two-thirds of cases. Maternal mortality rate was 6.7% and neonatal mortality rate 9.1%. CONCLUSIONS: This is the largest case series of surgery for CD during pregnancy. This operation may have significant morbidity and mortality for mother, fetus, and newborn. Indication needs to be tailored to maternal status, disease severity, and gestational age. Surgery should be managed by experienced gynecologists, physicians, and surgeons. Active CD may be associated with a greater risk to the fetus than the surgical procedure itself.
