Suprapubic versus transurethral catheterization for bladder drainage in male rectal cancer surgery (GRECCAR10), a randomized clinical trial.

BACKGROUND: Bladder drainage is systematically used in rectal cancer surgery; however, the optimal type of drainage, transurethral catheterization (TUC) or suprapubic catheterization (SPC), is still controversial. The aim was to compare the rates of urinary tract infection on the fourth postoperative day (POD4) between TUC and SPC, after rectal cancer surgery regardless of the day of removal of the urinary drain. METHODS: This randomized clinical trial in 19 expert colorectal surgery centers in France and Belgium was performed between October 2016 and October 2019 and included 240 men (with normal or subnormal voiding function) undergoing mesorectal excision with low anastomosis for rectal cancer. Patients were followed at postoperative days 4, 30, and 180. RESULTS: In 208 patients (median age 66 years [IQR 58-71]) randomized to TUC (n = 99) or SPC (n = 109), the rate of urinary infection at POD4 was not significantly different whatever the type of drainage (11/99 (11.1%) vs. 8/109 (7.3%), 95% CI, - 4.2% to 11.7%; p = 0.35). There was significantly more pyuria in the TUC group (79/99 (79.0%) vs. (60/109 (60.9%), 95% CI, 5.7-30.0%; p = 0.004). No difference in bacteriuria was observed between the groups. Patients in the TUC group had a shorter duration of catheterization (median 4 [2-5] vs. 4 [3-5] days; p = 0.002). Drainage complications were more frequent in the SPC group at all followup visits. CONCLUSIONS: TUC should be preferred over SPC in male patients undergoing surgery for mid and/or lower rectal cancers, owing to the lower rate of complications and shorter duration of catheterization.

Risk factors for severe morbidity and definitive stoma after elective surgery for sigmoid diverticulitis: a multicenter national cohort study.

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).

Learning curve for robotic-assisted total mesorectal excision: a multicentre, prospective study.

AIM: Robotic-assisted surgery (RAS) is becoming increasingly important in colorectal surgery. Recognition of the short, safe learning curve (LC) could potentially improve implementation. We evaluated the extent and safety of the LC in robotic resection for rectal cancer. METHOD: Consecutive rectal cancer resections (January 2018 to February 2021) were prospectively included from three French centres, involving nine surgeons. LC analyses only included surgeons who had performed more than 25 robotic rectal cancer surgeries. The primary endpoint was operating time LC and the secondary endpoint conversion rate LC. Interphase comparisons included demographic and intraoperative data, operating time, conversion rate, pathological specimen features and postoperative morbidity. RESULTS: In 174 patients (69% men; mean age 62.6 years) the mean operating time was 334.5 ± 92.1 min. Operative procedures included low anterior resection (n = 143) and intersphincteric resection (n = 31). For operating time, there were two or three (centre-dependent) LC phases. After 12-21 cases (learning phase), there was a significant decrease in total operating time (all centres) and an increase in the number of harvested lymph nodes (two centres). For conversion rate, there were two or four LC phases. After 9-14 cases (learning phase), the conversion rate decreased significantly in two centres; in one centre, there was a nonsignificant decrease despite the treatment of significantly more obese patients and patients with previous abdominal surgery. There were no significant differences in interphase comparisons. CONCLUSION: The LC for RAS in rectal cancer was achieved after 12-21 cases for the operating time and 9-14 cases for the conversion rate. RAS for rectal cancer was safe during this time, with no interphase differences in postoperative complications and circumferential resection margin.

Intestinal Conventional Ultrasonography, Contrast-Enhanced Ultrasonography and Magnetic Resonance Enterography in Assessment of Crohn's Disease Activity: A Comparison with Surgical Histopathology Analysis.

BACKGROUND AND AIMS: Contrast-enhanced ultrasonography (CEUS) is a potential interesting method for assessing accurately Crohn's disease (CD) activity. We compared the value of intestinal ultrasonography (US) coupled with contrast agent injection with that of magnetic resonance enterography (MRE) in the assessment of small bowel CD activity using surgical histopathology analysis as reference. METHODS: Seventeen clinically active CD patients (14 women, mean age 33 years) requiring an ileal or ileocolonic resection were prospectively enrolled. All performed a MRE and a US coupled with contrast agent injection (CEUS) less than 8 weeks prior to surgery. Various imaging qualitative and quantitative parameters were recorded and their respective performance to detect disease activity, disease extension and presence of complications was compared to surgical histopathological analysis. RESULTS: The median wall thickness measured by US differed significantly between patients with non-severely active CD (n = 5) and those with severely active CD (n = 12) [7.0 mm, IQR (6.5-9.5) vs 10.0 mm, IQR (8.0-12.0), respectively; p = 0.03]. A non-significant trend was found with MRE with a median wall thickness in severe active CD of 10.0 mm, IQR (8.0-13.7) compared with 8.0 mm, IQR (7.5-10.5) in non-severely active CD (p = 0.07). The area under the ROC curve (AUROC) of the wall thickness assessed by US and MRE to identify patients with or without severely active CD on surgical specimens were 0.85, 95% CI (0.64-1.04), p = 0.03 and 0.80, 95% CI (0.56-1.01), p = 0.07, respectively. Among the parameters derived from the time-intensity curve during CEUS, time to peak and rise time were the two most accurate markers [AUROC = 0.88, 95% CI (0.70-1.04), p = 0.02 and 0.86, 95% CI (0.68-1.04), p = 0.03] to detect patients with severely active CD assessed on surgical specimens. CONCLUSION: The accuracy of intestinal CEUS is close to that of conventional US to detect disease activity. A thickened bowel and shortened time to peak and rise time were the most accurate to identify CD patients with severe histological disease activity.

International variation in managing locally advanced or recurrent rectal cancer: prospective benchmark analysis.

BACKGROUND: Tumour extension beyond the mesorectal plane (ymrT4) occurs in 5-10 per cent of patients with rectal cancer and 10 per cent of patients develop locally recurrent rectal cancer (LRRC) after primary surgery. There is global variation in healthcare delivery for these conditions. METHODS: An international benchmark trial of the management of ymrT4 tumours and LRRC was undertaken in France and Australia between 2015 and 2017. Heterogeneity in management and operative decision-making were analysed by comparison of surgical resection rates, blinded intercountry reading of pelvic MRI, quality-of-life assessment and qualitative evaluations. RESULTS: Among 154 patients (97 in France and 57 in Australia), 31·8 per cent had ymrT4 disease and 68·2 per cent LRRC. The surgical resection rates were 88 and 79 per cent in France and Australia respectively (P = 0·112). The concordance in operative planning was low (κ = 0·314); the rate of pelvic exenteration was lower in France than Australia both in clinical practice (36 of 78 versus 34 of 40; P < 0·001) and in theoretical conditions (10 of 25 versus 50 of 57; P = 0·002). The R0 resection rate was lower in France than Australia for LRRC (25 of 49 versus 18 of 21; P = 0·007) but not for ymrT4 tumours (21 of 26 versus 15 of 15; P = 0·139). Morbidity rates were similar. Patients who underwent non-exenterative procedures had higher scores on the mental functioning subscale at 12 months (P = 0·047), and a lower level of distress at 6 months (P = 0·049). Qualitative analysis highlighted five categories of psychosocial factors influencing treatment decisions: patient, strategy, specialist, organization and culture. CONCLUSION: This international benchmark trial has highlighted the differences in worldwide treatment of locally advanced and LRRC. Standardized care should improve outcomes for these patients.

ANTECEDENTES: La extensión del tumor más allá del plano del meso-rrecto (ymrT4) ocurre en el 5-10% de los pacientes con cáncer de recto y el 10% de los pacientes desarrollan recidiva local del cáncer de recto (locally recurrent rectal cáncer, LRRC) después de una cirugía primaria. Existe una variación global en la prestación de la asistencia sanitaria para esta pato-logía. MÉTODOS: Se realizó un ensayo de referencia internacional sobre el manejo de ymrT4 y LRRC en Francia y Australia entre 2015 y 2017. La heterogeneidad en el manejo y la toma de decisiones quirúrgicas se analizaron mediante la comparación de las tasas de resección quirúrgica, la lectura a ciegas de la resonancia magnética (RM) pélvica entre países, la evaluación de la calidad de vida y las evaluaciones cualitativas. RESULTADOS: De 154 pacientes (97 en Francia versus 57 en Australia), el 32% tenía ymrT4 y el 68% tenía cáncer de recto con recidiva local. Las tasas de resección quirúrgica fueron del 87,6% versus 77,8% (P = 0,112). La tasa de concordancia en la decisión quirúrgica fue baja (coeficiente kappa = 0,314) con una tasa más baja de exenteración pélvica en Francia, tanto en la práctica clínica (46% versus 85%; P < 0,0001) como en condiciones teóricas (40% versus 88%; P = 0,002). La tasa de resección R0 fue menor en Francia para la LRRC (51% versus 86%, P = 0,007) pero no para el ymrT4 (81% versus 100%, P = 0,139). Las tasas de morbilidad fueron similares. Los pacientes que se sometieron a procedimientos no exenterativos tuvieron una subescala de funcionamiento mental más alta a los 12 meses (P = 0,04) y un nivel de angustia más bajo a los 6 meses (P = 0,04). El análisis cualitativo destacó 5 categorías de factores psicosociales que afectaron a la decisión del tratamiento: paciente, estrategia, especialista, organización y cultura. CONCLUSIÓN: Este ensayo de referencia internacional destaca las diferencias en el tratamiento mundial del cáncer de recto localmente avanzado y de la LRR. La aten-ción estandarizada debería mejorar los resultados para estos pacientes.

Intolerance to early oral feeding in enhanced recovery after colorectal surgery: an early red flag?

AIM: Enhanced recovery programmes (ERPs) involve early postoperative oral feeding. The aim of this study was to test the hypothesis that intolerance to early feeding was associated with a complicated postoperative course. METHOD: A retrospective cohort analysis of the prospective multicentre database developed by the Francophone Group for Enhanced Recovery after Surgery (GRACE) was undertaken. Seventy-one centres in Belgium, France and Switzerland participated in the study. All patients were encouraged to eat within 24 h after surgery. Patients were separated into two groups according to whether early feeding was well tolerated (WT) or poorly tolerated (PT). The primary outcome measure was overall postoperative complications. Secondary outcome measures were unplanned reoperation, early mobilization rate and duration of postoperative hospital stay. RESULTS: Among the cohort of 3034 patients, early feeding was WT in 2614 patients (WT group) and PT in 420 patients (PT group). There were significantly more postoperative complications in the PT group than in the WT group (52.1% vs 17.0%, respectively; P = 0.001), namely more unplanned reoperations, less early mobilization and longer postoperative hospital stay. Multivariate analyses confirmed that PT early feeding was the main and dominant independent factor for postoperative complications [OR 4.47 (95% CI3.49-5.72); P < 0.001], more unplanned reoperations and longer hospital stay. CONCLUSIONS: This study demonstrates a close relationship between intolerance to early feeding and a complicated postoperative course. Whenever this simple very early red flag is observed, discharge should not be planned until postoperative complications have been ruled out.

Incidence and Risk Factors for Severity of Postoperative Ileus After Colorectal Surgery: A Prospective Registry Data Analysis.

BACKGROUND: Defining severe postoperative ileus in terms of consequences could help physicians standardize the management of this condition. The recently described classification based on consequences requires further investigation. The aim of this study was to obtain a snapshot of postoperative ileus in patients undergoing colorectal surgery within enhanced recovery programs and to identify factors associated with non-severe and severe postoperative ileus. METHODS: This prospective registry data analysis was conducted in 40 centers in five different countries. A total of 786 patients scheduled for colorectal surgery within enhanced recovery programs were included. The primary endpoint was the incidence rate of postoperative ileus as defined by Vather et al. RESULTS: A total of 121 patients experienced postoperative ileus (15.4%). Non-severe POI occurred in 48 patients (6.1%), and severe postoperative ileus occurred in 73 patients (9.3%). In multivariate analysis, the male gender and intra-abdominal complications were associated with severe postoperative ileus: odd ratio (OR) = 2.03 [95% confidence interval (CI) 1.14-3.59], p = 0.01 and OR = 3.60 [95% CI 1.75-7.40], p < 0.0001, respectively. Conversely, open laparotomy and urinary retention were associated with non-severe POI: OR = 3.03 [95% CI 1.37-6.72], p = 0.006 and OR = 2.70 [95% CI 0.89-8.23], p = 0.08, respectively. CONCLUSIONS: Postoperative ileus occurred in 15% of patients after colorectal surgery within enhanced recovery programs. For 60% of patients, this was considered severe. The physiopathology of these two entities could be different, severe POI being linked to intraabdominal complication, while non-severe POI being linked with risk factors for "primary" POI. The physician should pay attention to male patients having POI after colorectal surgery and look for features evocating intraabdominal complications.

Pramipexole-responsive acute restless arms syndrome after surgery under general anesthesia: Case report and literature review.

We reported a case of acute restless arms syndrome occurring after colorectal surgery under general anaesthesia. This case was also compared with other cases of restless legs/arms syndromes occurring in a perioperative context through a literature review. As the restless legs syndrome, the restless arms syndrome can be exacerbated by perioperative procedures and improved with pramipexole from the first day of treatment. This case reinforces the idea that the restless arms syndrome seems to be subsumed along with the restless legs syndrome, and is a further argument to use the diagnosis term "restless limb syndrome" for the restlessness of any limb with clinical features similar to the restless legs syndrome.

Intraperitoneal-Free Cancer Cells Represent a Major Prognostic Factor in Colorectal Peritoneal Carcinomatosis.

BACKGROUND: Intraperitoneal-free cancer cells are considered as an important prognostic tool in gastric and ovarian cancer. However, their significance in colorectal cancer remains more controversial. OBJECTIVE: This study aimed to determine the role of intraperitoneal-free cancer cells as a prognostic tool in the outcome in colorectal peritoneal carcinomatosis treated with curative intent by complete cytoreductive surgery. DESIGN: This study is an analysis of a prospectively maintained database. PATIENTS: Between 1991 and 2012, all patients treated in a single institution for colorectal peritoneal carcinomatosis by complete cytoreductive surgery with peritoneal cytology available were evaluated. Peritoneal cytology was stained in the conventional way (May Grumwald Giemsa). RESULTS: Among a population of 162 patients treated for colorectal peritoneal carcinomatosis by complete cytoreductive surgery, 38 presented positive intraperitoneal-free cancer cells (23.5%). Systemic chemotherapy was administered to 135 patients (85%) during the preoperative course. Median follow-up was 34.5 months. Median overall survival was 19 and 44 months for positive and negative intraperitoneal-free cancer cells (p = 0.018). In multivariate analysis, Peritoneal Carcinomatosis Index and positive intraperitoneal-free cancer cells were significant prognostic factors of overall survival (HR, 2.3 (1.18-4.52), p = 0.014; HR, 1.9 (1.08-3.38), p = 0.027). LIMITATIONS: Retrospective analysis and the long period were limitations of study. CONCLUSION: Along with the Peritoneal Carcinomatosis Index, intraperitoneal-free cancer cells are a strong prognostic factor for patients treated with curative intent for colorectal peritoneal carcinomatosis by complete cytoreductive surgery. The presence of intraperitoneal-free cancer cells should lead to the consideration of different treatment strategies such as extensive intraperitoneal lavage, targeted intraperitoneal therapies, or repeated intraperitoneal chemotherapy.

Malignant peritoneal mesothelioma treated by cytoreductive surgery and hyperthermic intraperitoneal chemotherapy: is GLUT1 expression a major prognostic factor? A preliminary study.

PURPOSE: Diffuse malignant peritoneal mesothelioma (DMPM) is a rare primary peritoneal malignancy. Its prognosis has been improved by an aggressive locoregional treatment combining extensive cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). Prognostic factors are currently poorly defined for this disease but are essential if treatment is to be standardized. METHODS: Twenty-eight patients with DMPM, who were considered preoperatively to be candidates for CRS and HIPEC between June 1998 and August 2010 at our institution, were selected for this study. Medical records and histopathological features were retrospectively reviewed and 24 clinical, histological, and immunohistochemical parameters were assessed for their association with overall survival by univariate and multivariate analyses. RESULTS: The following factors were significantly associated with overall survival by univariate analysis: predominant histological growth pattern in the epithelioid areas, nuclear grooves in the epithelioid areas, atypical mitoses, and calretinin and GLUT1 expression by immunohistochemistry in the epithelioid areas. Expression of the facilitative glucose transporter protein GLUT1 in the epithelioid areas was the only factor independently associated with overall survival by multivariate analysis. CONCLUSIONS: GLUT1 expression appears to be an indicator of poor prognosis in DMPM. Standard histological classification of DMPM may not be adequate to select patients for aggressive locoregional treatments, such as CRS and HIPEC. Multicenter validation of the prognostic factors identified in this preliminary study is needed to refine patient selection for potential cure.

Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) for persistent and recurrent advanced ovarian carcinoma: a multicenter, prospective study of 246 patients.

BACKGROUND: Epithelial ovarian carcinoma is the main cause of death from gynaecological cancers in the western world. The initial response rate to the frontline therapy is high. However, the prognosis of persistent and recurrent disease remains poor. During the two past decades, a new therapeutic approach to peritoneal carcinomatosis has been developed, combining maximal cytoreductive effort with hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: A retrospective, multicentric study of 246 patients with recurrent or persistent ovarian cancer, treated by cytoreductive surgery and HIPEC in two French centers between 1991 and 2008, was performed. RESULTS: An optimal cytoreductive surgery was possible in 92.2 % of patients. Mortality and morbidity rates were 0.37 % and 11.6 %, respectively. The overall median survival was 48.9 months. There was no significant difference in overall survival in patients with persistent or recurrent disease. In multivariate analysis, performance status was a significant prognostic factor in patients with extensive peritoneal carcinomatosis (peritoneal cancer index >10). CONCLUSIONS: Salvage therapy combining optimal cytoreductive surgery and HIPEC is feasible and may achieve long-term survival in highly selected patients with recurrent ovarian carcinoma, including those with platinum resistant disease, with acceptable morbidity.

Intraperitoneal free cancer cells in non-gynaecological adenocarcinomas: a reproducibility study.

OBJECTIVE: In recent years, therapeutic approaches including cytoreductive surgery followed by intraperitoneal chemotherapy have proven effective in peritoneal carcinomatosis of colorectal origin. If cytology is to be used to include patients in aggressive treatment regimens, it is necessary to evaluate its performance, particularly in terms of specificity. The aim of this study was to assess interobserver agreement for the detection of intraperitoneal free cancer cells (IFCCs) in patients with non-gynaecological adenocarcinomas. METHODS: Over a 5-year period, 1223 patients were recruited in 19 French surgery departments. Peritoneal samples were examined in 14 dispersed pathology laboratories. Giemsa-stained slides were sent to a control reader blind to the previous diagnosis. Discordant cases, concordant positive results and a random selection of negative concordant cases were reviewed by a panel of seven cytopathologists. The 'final diagnosis' was that of the consensus meetings but took into account locally-processed slides. RESULTS: Gathering dubious cases with negative results, a 95.6% concordance was achieved between local readers and the control reader. IFCCs were ascertained by the panel in 85 cases (7.0%). Eight of 873 colorectal cancers cases viewed locally were falsely positive (0.9%). Radiotherapy and neoadjuvant therapy had no impact on the false-positive rate as assessed by final validation by the panel (P > 0.05). Samples initially considered as dubious were reclassified as negative by the panel in 24 of 25 cases (96.0%). CONCLUSIONS: The panel consensus allowed reclassification of most dubious/equivocal peritoneal cytology cases, whereas clearcut distinction between benign and malignant cases was correctly achieved in almost all cases.

Robotic-assisted right colectomy. Official expert recommendations delivered under the aegis of the French Association of Surgery (AFC).

Twenty-seven experts under the aegis of the French Association of Surgery (AFC) offer this reference system with formalized recommendations concerning the performance of right colectomy by robotic approach (RRC). For RRC, experts suggest patient installation in the so-called "classic" or "suprapubic" setup. For patients undergoing right colectomy for a benign pathology or cancer, RRC provides no significant benefit in terms of intra-operative blood loss, intra-operative complications or conversion rate to laparotomy compared to laparoscopy. At the same time, RRC is associated with significantly longer operating times. Data from the literature are insufficient to define whether the robot facilitates the performance of an intra-abdominal anastomosis, but the robotic approach is more frequently associated with an intra-abdominal anastomosis than the laparoscopic approach. Experts also suggest that RRC offers a benefit in terms of post-operative morbidity compared to right colectomy by laparotomy. No benefit is retained in terms of mortality, duration of hospital stay, histological results, overall survival or disease-free survival in RRC performed for cancer. In addition, RRC should not be performed based on the cost/benefit ratio, since RRC is associated with significantly higher costs than laparoscopy and laparotomy. Future research in the field of RRC should consider the evaluation of patient-targeted parameters such as pain or quality of life and the technical advantages of the robot for complex procedural steps, as well as surgical and oncological results.

Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for peritoneal carcinomatosis from colorectal cancer: a 13 years-retrospective monocentric study.

Background and study aim: Over the last 20 years, cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) has progressively become a therapeutic option for peritoneal carcinomatosis thanks to its favourable oncologic results. The aim of this study is to analyse the overall survival and recurrence-free survival, after complete CRS and closed abdomen technique HIPEC for peritoneal carcinomatosis from colorectal cancer. Patients and methods: This retrospective study collected the data from all patients who underwent a CRS with HIPEC for colorectal cancer at "Cliniques universitaires Saint Luc" from October 2007 to December 2020. Ninety-nine patients were included. Results: The median follow-up was 34 months. Post-operative mortality and Clavien-Dindo grade III/IV morbidity rates were 2.0% and 28.3%. The overall 2-year and 5-year survival rates were 80.1% and 54.4%. Using the multivariate analysis, age at surgery, liver metastases and PCI score >13 showed a statistically significant negative impact on overall survival. The 2-year and 5-year recurrence-free survival rates were 33.9% and 22%. Using the multivariate analysis, it was found that liver metastases, the extent of carcinomatosis with PCI>7 have a statistically significant negative impact on recurrence-free survival. Conclusions: Despite a high recurrence rate, CRS followed by HIPEC to treat peritoneal carcinomatosis from colorectal origin offer encouraging oncologic results with a satisfying survival rate. When PCI>13, CRS and HIPEC does not seem to offer any survival benefit and to efficiently limit recurrence, our data are in favor of a maximum PCI of 7.

A Reappraisal of Outcome of Elective Surgery After Successful Non-Operative Management of an Intra-Abdominal Abscess Complicating Ileocolonic Crohn's Disease: A Subgroup Analysis of a Nationwide Prospective Cohort.

BACKGROUND AND AIMS: Few prospective data exist on outcomes of surgery in Crohn's disease [CD] complicated by an intra-abdominal abscess after resolution of this abscess by antibiotics optionally combined with drainage. METHODS: From 2013 to 2015, all patients undergoing elective surgery for CD after successful non-operative management of an intra-abdominal abscess [Abscess-CD group] were selected from a nationwide multicentre prospective cohort. Resolution of the abscess had to be computed tomography/magnetic resonance-proven prior to surgery. Abscess-CD group patients were 1:1 matched to uncomplicated CD [Non-Penetrating-CD group] using a propensity score. Postoperative results and long-term outcomes were compared between the two groups. RESULTS: Among 592 patients included in the registry, 63 [11%] fulfilled the inclusion criteria. The abscess measured 37 ±â€…20 mm and was primarily managed with antibiotics combined with drainage in 14 patients and nutritional support in 45 patients. At surgery, a residual fluid collection was found in 16 patients [25%]. Systemic steroids within 3 months before surgery [p = 0.013] and the absence of preoperative enteral support [p = 0.001] were identified as the two significant risk factors for the persistence of a fluid collection. After propensity score matching, there was no significant difference between the Abscess-CD and Non-Penetrating-CD groups in the rates of primary anastomosis [84% vs 90% respectively, p = 0.283], overall [28% vs 15% respectively, p = 0.077] and severe postoperative morbidity [7% vs 7% respectively, p = 1.000]. One-year recurrence rates for endoscopic recurrence were 41% in the Abscess-CD and 51% in the Non-Penetrating-CD group [p = 0.159]. CONCLUSIONS: Surgery after successful non-operative management of intra-abdominal abscess complicating CD provides good early and long-term outcomes.

[Contribution of meb to endometriosis patients' diagnosis and treatment]. / Apport de la réunion de concertation pluridisciplinaire à la pertinence du diagnostic et du traitement de l'endométriose.

OBJECTIVES: Diagnosis and treatment of endometriosis may be complex and therefore justify the discussion of therapeutic decisions in a multidisciplinary endometriosis board (MEB). The development of endometriosis regional expert centers requires an assessment of the quality and relevance of MEB. METHODS: Qualitiative retrospective study on patients whose management was discussed in Centre Hospitalier Lyon-Sud between June 2013 and December 2017. RESULTS: Among 376 patients presented in MEB, 309 (80.2%) were painful and 184 (59.5%) had complex endometriosis. A complete clinical evaluation was performed in 120 (38.8%) patients. MRI was performed for 370 (98.4%) patients including 303 (81.9%) with a second reading by an expert radiologist. These second readings allowed a diagnosis correction in 88 (60.7 %) patients with complex endometriosis. MR enterography (27.8 %) and rectal endoscopic sonography (14.4%) were the most frequently used third-line exams to complete the initial imaging of digestive lesion in patients with rectal endometriosis. Surgery was proposed for 199 (52,9%) patients including 108 (58,7%) with complex endometriosis. CONCLUSION: One of the major interests of MEB in endometriosis is the second reading of MRI, which, by identifying complex endometriosis initially undiagnosed or underestimated, enabled to better discuss the benefits/risks of therapeutic choices, and to organize complex surgeries when those were retained. The development of MEB in regional expert centers will contribute to optimizing the relevance of care for patients with endometriosis.

[Hyperthermic intraperitoneal chemotherapy for the treatment of peritoneal carcinomatosis arising from gastric cancer]. / Chimiohyperthermie intrapéritonéale dans le traitement des carcinoses péritonéales d'origine gastrique.

Since 20 years, treatment of peritoneal carcinomatosis has been developed in expert centers. Cytoreductive surgery and perioperative intraperitoneal chemotherapy, especially hyperthermic intraperitoneal chemotherapy, was assessed by many nonrandomised studies for the treatment of peritoneal carcinomatosis arising from gastric cancer. Results described increased survival, especially for the most favourable cases: limited carcinomatosis and complete cytoreductive surgery. A strict selection of the patients is necessary because of the important morbidity of those treatments. Only patients with good general health, able to tolerate a threatening treatment, with possible complete cytoreduction, may benefit from those treatments. Many japanese studies had demonstrated the efficacy of hyperthermic intraperitoneal chemotherapy for the prophylactic treatment of carcinomatosis in advanced-gastric cancers. These results have to be confirmed by european randomised studies.

[Peritoneal mesothelioma: treatment with cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy]. / Mésothéliome péritonéal: traitement par l'association chirurgie de cytoréduction et chimiothérapie hyperthermique intrapéritonéale.

UNLABELLED: Diffuse malignant peritoneal mesothelioma is a rare and lethal disease. Locoregional treatments combining cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) seem to improve prognosis. METHODS: Cytoreductive surgery and HIPEC was performed in 22 patients at the Centre Hospitalier-Lyon Sud between 1989 and 2006. A retrospective analysis of survival was carried out to assess clinical and histological prognostic factors. RESULTS: Nineteen patients with diffuse malignant peritoneal mesothelioma were included (16 epithelial, 3 biphasic and 3 multicystic forms). Sixteen patients presented stage 3 or 4 peritoneal mesothelioma according to the Gilly classification. Optimal cytoreductive surgery was performed for 11 patients (complete macroscopic resection or residual tumor nodules less than 2.5mm). No post-operative deaths occurred but 9 patients (47%) presented grade III or IV post-operative complications. The overall median survival was 36.9 months; completeness of cytoreduction was the only significant prognostic factor. CONCLUSION: Cytoreductive surgery combined with HIPEC may improve the length of survival for patients with diffuse malignant peritoneal mesothelioma; such patients should be treated in specialized centers.
