RESUMEN
OBJECTIVE: The aim of this study was to assess the effectiveness of sacral nerve modulation (SNM) in a large cohort of patients implanted for at least 10 years, quantify adverse event rates, and identify predictive factors of long-term success. SUMMARY BACKGROUND DATA: Few studies have evaluated the long-term success of SNM. METHODS: Data collected prospectively from patients implanted for fecal incontinence (FI) in 7 French centers between January 1998 and December 2008 were retrospectively analyzed. Patient FI severity scores were assessed before and 10 years after implantation. The main evaluation criterion was the success of SNM defined by the continuation of the treatment without additional therapies. The secondary evaluation criteria were the rate of device revisions and explantations. Preoperative predictors of success at 10 years were sought. RESULTS: Of the 360 patients (27 males, mean age: 59 ± 12 years) implanted for FI, 162 (45%) had a favorable outcome 10 years post-implantation, 115 (31.9%) failed, and 83 (23.1%) were lost to follow-up. The favorable outcome derived from the time-to-event Kaplan-Meier curve at 10 years was 0.64 (95% CI 0.58-0.69). FI severity scores were significantly better 10 years post-implantation compared to preimplantation (7.4 ± 4.3 vs 14.0 ± 3.2; P < 0.0001). During the 10-year follow-up, 233 patients (64.7%) had a surgical revision and 94 (26.1%) were explanted. A history of surgery for FI and sex (male) were associated with an increased risk of an unfavorable outcome. CONCLUSIONS: Long-term efficacy was maintained in approximately half of the FI patients treated by SNM at least 10 years post-implantation.

The aim is to evaluate the feasibility and the prognosis of cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) for resectable peritoneal metastases (RPM) in elderly patients. Patients who underwent CRS with HIPEC for RPM between 2012 and 2018 in one tertiary reference center were retrospectively included and divided according to the age: Group A (< 65 years) and Group B (≥ 65 years). Postoperative outcomes and survivals were compared. Ninety-five patients were included in Groups A (n = 65) and B (n = 30). The incidence of comorbidities was significantly higher in elderly patients (65 vs 90%, p = 0.01), but RPM characteristics were similar between groups. There was no difference between groups in terms of postoperative results: 30-day major morbidity (33 vs 23%, p = 0.4), 30-day mortality (0 vs 3%, p = 0.3), mean length of stay (26.7 ± 19.4 vs 22.4 ± 10.3 days, p = 0.3) and readmission's rate (15 vs 33%, p = 0.06). The only one significant difference was the 90-day mortality which never occurred before 65 years but in 10% of elderly patients (p = 0.03). There was no difference regarding recurrence's rate (56 vs 37%, p = 0.1), neither 1-, 3- and 5-year overall survival rates (86, 64 and 52% vs 85, 74% and not reached, p = 0.8) and disease-free survival rates (61, 28 and 28% vs 56, 45% and not reached, p = 0.6). CRS with HIPEC is feasible in elderly patients. Since the 90-day mortality appeared to be higher in elderly patients, additional criteria are necessary to improve the selection of elderly patients for this major surgery.

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 intervalâ=â(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.

PURPOSE: Volume-outcome relationship is well established in elective colorectal surgery for cancer, but little is known for patients managed for obstructive colon cancer (OCC). We aimed to compare the management and outcomes according to the hospital volume in this particular setting. METHODS: Patients managed for OCC between 2005 and 2015 in centers of the French National Surgical Association were retrospectively analyzed. Hospital volume was dichotomized between low and high volume on the median number of patients included per center during the study period. RESULTS: A total of 1957 patients with OCC were managed in 56 centers with a median number of 28 (1-123) patients per center: 298 (15%) were treated in low-volume hospitals (LVHs) and 1659 (85%) in high-volume hospitals (HVHs). Patients in LVH were significantly younger, and had fewer comorbidities and synchronous metastases. Proximal diverting stoma was the preferred surgical option in LVH (p < 0.0001), whereas tumor resection with primary anastomosis was more frequently performed in HVH (p < 0.0001). Cumulative morbidity (59 vs. 50%, p = 0.003), mortality (13 vs. 8%, p = 0.03), and length of hospital stay (22 ± 19 vs. 18 ± 14 days, p = 0.002) were significantly higher in LVH. At multivariate analysis, LVH was a predictor for cumulative morbidity (p < 0.0001) and mortality (p = 0.03). There was no difference between the two groups for tumor resection and stoma rates, and for oncological outcomes. CONCLUSIONS: The hospital volume has no impact on outcomes after the first-stage surgery in OCC patients. When all surgical stages are considered, hospital volume influences cumulative postoperative morbidity and mortality but has no impact on oncological outcomes.

OBJECTIVE: To assess the efficacy and safety of sacral nerve modulation (SNM) in patients with faecal incontinence (FI) after pelvic radiotherapy in comparison with results of SNM for FI related to other conditions. METHODS: Prospectively collected data from patients who underwent SNM therapy between January 2010 and December 2015 at 7 tertiary colorectal units were reviewed retrospectively. Patients with FI following pelvic radiotherapy were identified and matched (1:2) for age and sex with 38 patients implanted over the same period for FI without previous radiotherapy. The treatment was considered favourable if the patient reported any therapeutic benefit from SNM, had no further complaints or interventions and did not consider stopping the treatment. Long-term results, surgical revision and definitive explantation rates were compared. RESULTS: Among 352 patients who received a permanent SNM implant, 19 (5.4%) had FI following pelvic radiotherapy. After a mean follow-up of 3.5 ± 1.9 years, the cumulative successful treatment rates were similar between the groups (p = 0.60). For patients with FI following pelvic radiotherapy, the cumulative success rates were 99.4% [85.4-99.8], 96.7% [78.1-99.6], 91.7% [70.4-98.1] and 74.6% [48.4-94.8] at 1, 2, 3 and 5 years respectively. The revision and definitive explantation rates for infection did not differ significantly. CONCLUSION: The long-term success rate of SNM for FI after pelvic radiotherapy is similar to that of SNM for FI related to other more frequent conditions. Our study suggests that FI after pelvic radiotherapy could be improved with SNM without an increased risk of complication.

BACKGROUND: Emergency surgery impairs postoperative outcomes in colorectal cancer patients. No study has assessed the relationship between obesity and postoperative results in this setting. OBJECTIVE: To compare the results of emergency surgery for obstructive colon cancer (OCC) in an obese patient population with those in overweight and normal weight patient groups. METHODS: From 2000 to 2015, patients undergoing emergency surgery for OCC in French surgical centers members of the French National Surgical Association were included. Three groups were defined: normal weight (body mass index [BMI] < 25.0 kg/m2), overweight (BMI 25.0-29.9 kg/m2), and obese (BMI ≥30.0 kg/m2). RESULTS: Of 1,241 patients, 329 (26.5%) were overweight and 143 (11.5%) were obese. Obese patients had significantly higher American society of anesthesiologists score, more cardiovascular comorbidity and more hemodynamic instability at presentation. Overall postoperative mortality and morbidity were 8 and 51%, respectively, with no difference between the 3 groups. For obese patients with left-sided OCC, stoma-related complications were significantly increased (8 vs. 5 vs. 15%, p = 0.02). CONCLUSION: Compared with lower BMI patients, obese patients with OCC had a more severe presentation at admission but similar surgical management. Obesity did not increase 30-day postoperative morbidity except stoma-related complications for those with left-sided OCC.

PURPOSE: At equal TNM stage, obstructing colon cancer (OCC) is associated with worse prognosis in comparison with uncomplicated cancer. Our aim was to identify prognostic factors of overall (OS) and disease-free survival (DFS) in patients treated for OCC. METHODS: From 2000 to 2015, 2325 patients were treated for OCC in French surgical centers, members of the French National Surgical Association (AFC). Patients with palliative management were excluded. The main endpoints were OS and DFS. A multivariate analysis, using Cox proportional hazards regression model, was performed to determine independent prognostic factors. RESULTS: The cohort included 2120 patients. The median of follow-up was 13.2 months. In multivariate analysis, age > 75 years, ASA score ≥ 3, ECOG score ≥ 3, right-sided colon cancer, presence of synchronous metastases, anastomotic leakage, and absence of adjuvant chemotherapy were independent OS factors. Age > 75 years, ASA score ≥ 3, right-sided colon cancer, presence of synchronous metastases, and absence of postoperative chemotherapy were independent factors of poor OS after exclusion of patients who died postoperatively. Age ≥ 75 years, ASA score ≥ 3, ECOG score ≥ 3, right-sided colon cancer, lymph node involvement, presence of vascular, lymphatic or perineural invasion, less than 12 harvested lymph nodes, and absence of adjuvant chemotherapy were independent DFS factors. CONCLUSIONS: Management of OCC should take into account prognostic factors related to the patient (age, comorbidities), tumor location, and tumor stage. Adjuvant chemotherapy administration plays an important role. For patients undergoing initial defunctionning stoma, neoadjuvant chemotherapy could be an option to improve prognosis.

OBJECTIVE: The objective was to assess the efficacy and the safety of sacral nerve modulation (SNM) in men with fecal incontinence (FI) compared with those of SNM in women. METHOD: Prospectively collected data from patients from seven tertiary colorectal units who underwent an implant procedure between January 2010 and December 2015 were reviewed retrospectively. Outcomes and surgical revision and definitive explantation rates were compared between men and women. RESULTS: A total of 469 patients (60 men [12.8%]; mean age = 61.4 ± 12.0 years) were included in the study, 352 (78.1%) (31 men [8.8%]) of whom received a permanent implant. The ratio of implanted/tested men was significantly lower than the ratio of implanted/tested women (p = 0.0004). After a mean follow-up of 3.4 ± 1.9 years, the cumulative successful treatment rates tended to be less favorable in men than in women (p = 0.0514): 88.6% (75.6-95.1), 75.9% (60.9-86.4), 63.9% (48.0-77.3), and 43.9% (26.7-62.7) at one, two, three, and five years, respectively, in men; 92.0% (89.1-94.2), 84.2% (80.3-87.4), 76.8% (72.3-80.7), and 63.6% (57.5-69.3) at one, two, three, and five years, respectively, in women. The revision rate for infection and the definitive explantation rate for infection were higher in men than in women (p = 0.0001 and p = 0.0024, respectively). CONCLUSION: Both short- and long-term success rates of SNM for FI were lower in men than in women. The revision and definitive explantation for long-term infection rates were significantly higher in men.

BACKGROUND: Although elderly patients constitute most of the patients undergoing surgery for obstructed colon cancer, available data in the literature are very limited. OBJECTIVE: The purpose of this study was to assess the management and outcomes of elderly patients treated for obstructed colon cancer. DESIGN: This was a multicenter, retrospective cohort study. SETTINGS: Between 2000 and 2015, 2325 patients managed for an obstructed colon cancer in member centers of the French National Surgical Association were identified. Data were collected by each center on a voluntary basis after institutional approval. Bowel obstruction was defined clinically and confirmed by imaging. PATIENTS: Three age groups were defined, including patients <75 years, 75 to 84 years, and ≥85 years. MAIN OUTCOME MEASURES: Postoperative and oncologic results in elderly patients with an obstructed colon cancer were measured. Relative survival was calculated as the ratio of the overall survival with the survival that would have been expected based on the corresponding general population. INTERVENTIONS: A total of 302 patients (13%) underwent colonic stent insertion, and 1992 (87%) underwent surgery as emergency procedure. RESULTS: A total of 2294 patients were analyzed (<75 y, n = 1200 (52%); 75-84 y, n = 650 (28%); and ≥85 y, n = 444 (20%)). Elderly patients were more likely to be women (p < 0.0001), to have proximal colon cancer (p < 0.0001), and to have a higher incidence of comorbidities (p < 0.0001). The use of colonic stent or the type of surgery was identical regardless of age. In patients with resected colon cancer, elderly patients had less stage IV disease (p < 0.0001). The absence of tumor resection (p < 0.0001) and definitive stoma rate increased with age (p < 0.0001). Postoperative mortality and morbidity were significantly higher in elderly patients (p < 0.0001), but surgical morbidity was similar across age groups (p = 0.60). Postoperative morbidity was correlated to the 6-month mortality rate in elderly (p < 0.0001). Overall and disease-free survivals were significantly lower in more elderly patients (p < 0.0001) but relative survival was not (p = 0.09). LIMITATIONS: It is quite difficult to know how to interpret these data as a whole, given the inherent bias in the study population, lack of ability to stratify by performance status, and long study period duration. CONCLUSIONS: Elderly patients have high morbidity with lower survival in the highest age ranges of elderly subgroups. These data should be considered when deciding on an operative approach.

Although hemorrhoids are recognized as a very common cause of rectal bleeding and known for a long time, its treatment has evolved dramatically over the last twenty years. Among the new minimally invasive methods, the "Emborrhoid" technique consists into selective embolization of hemorrhoidal arteries, branches arising from the superior rectal arteries using microcoils. This technique is based on a demonstrated pathophysiological concept of arterial network hypertrophy in hemorrhoid disease. This technique was evaluated in an animal model and then in clinical research on more than 100 patients. No ischemic complications were identified. Studies describe an improvement of 60 to 80% of the symptoms, with on average 30% recurrences at two years. The recurrence rae is likely related to a technically incomplete embolization. Future prospects are focused on more selective embolization with Particulate embolic agents.

PURPOSE: Few studies compared management and outcomes of obstructing colonic cancer (OCC), according to the tumor site. Our aim was to compare patient and tumor characteristics, postoperative and pathological results, and oncological outcomes after emergency management of right-sided vs. left-sided OCC. METHODS: A national cohort study including all consecutive patients managed for OCC from 2000 to 2015 in French surgical centers members of the French National Surgical Association (AFC). RESULTS: During the study period, 2325 patients with OCC were divided in right-sided (n = 819, 35%) and left-sided (n = 1506, 65%) locations. Patients with right-sided OCC were older, more frequently females, and associated with comorbidities, history of cancer, or previous laparotomy. Surgical management was more frequently performed for right-sided than left-sided OCC (99 vs. 96%, p < 0.0001). Tumor resection was more frequently performed in right-sided OCC (95 vs. 90%, p < 0.0001). Among the resected patients, primary anastomosis was more frequently performed in case of right-sided OCC (86 vs. 62%, p < 0.0001). Definitive stoma rate was lower in right-sided location (17 vs. 46%, p < 0.0001). There was no significant difference between locations in terms of cumulative morbidity, anastomotic leak, unplanned reoperation, and mortality. Five-year overall and disease-free survival rates were significantly lower in right-sided OCC (43 and 36%) than in left-sided OCC (53 and 46%, p < 0.0001 and p = 0.001, respectively). CONCLUSIONS: Although patients with right-sided OCC are frailer than left-sided OCC, tumor resection and anastomosis are more frequently performed, without difference in surgical results. However, right-sided OCC is associated with worse prognosis than distal location.

BACKGROUND: Endoscopic stent (ES) as a bridge to surgery in obstructed left colon cancer (OLCC) is controversial. Our goal was to compare the operative and oncological results of primary diverting colostomy (PDC) and ES for the curative treatment of OLCC. METHODS: Between 2000 and 2015, patients who underwent PDC or ES in a curative intent for OLCC at member centers of the French Surgical Association were included. Patients with unresectable tumors and/or synchronous metastases were excluded. Comparisons between the two groups were performed after ponderation with propensity score for: demographic and tumor characteristics, operative, and oncological results. RESULTS: A total of 518 patients were included: PDC (n = 327); ES (n = 191). The demographic characteristics were similar between the groups. ES failed in 23% of the patients (11% perforation). Cumulative tumor resection rates were 80% and 86% after PDC and ES, respectively (p = 0.049). The rates of primary anastomosis were 57% in the PDC group and 40% in the ES group (p < 0.0001). The permanent stoma rates were similar between the two groups (29% vs. 28%, p = 0.0586). Cumulative overall, surgical, and medical complications were significantly higher in PDC group. The resected tumors were significantly smaller and less frequently perforated and metastatic in the PDC group. The median overall survival was significantly higher after PDC (123.6 vs. 58.5 months, p = 0.046), whereas the median disease-free survival was similar between the two groups (54.1 vs. 53.6 months, p = 0.646). CONCLUSIONS: Although endoscopic stenting is associated with better surgical outcomes than diverting stoma, it may negatively impact histological features and overall survival.

AIM: To report the results of surgery for obstructive right colon cancer (ORCC) and to identify risk factors associated with worse outcomes that may help surgeons to choose the best surgical option. METHODS: This is a retrospective national cohort study, including all patients operated on for ORCC from 2000 to 2015. Those treated with colonic stent or symptomatic treatment were excluded. We described outcomes after surgery for ORCC and performed multivariate analyses for mortality, morbidity and survival. RESULTS: Among 776 patients analyzed, 716 (92%) had their primary tumor removed, with primary anastomosis in 582 (82%). The remaining 194 underwent anastomosis with loop ileostomy (n = 21), resection with double-end stoma (n = 113), defunctioning stoma without resection (n = 48) and ileocolic by-pass (n = 12). Postoperative mortality, morbidity and anastomotic leak rates were 10%, 51% and 14%, respectively. In multivariate analysis, age >70, ASA score ≥3 and hemodynamic instability were predictors of postoperative mortality whereas ASA score ≥3, hemodynamic instability and intra-operative complications were predictors of severe morbidity. No factors were correlated with anastomotic leak. After a median follow-up of 26 months, 8% of patients were alive with a permanent stoma. Five-year overall, disease-free and cancer-specific survival was 42%, 42% and 62%, respectively. In multivariate analysis, peritonitis, synchronous metastases and absence of adjuvant chemotherapy were predictors of decreased overall survival. CONCLUSIONS: Emergency surgery for ORCC is associated with high mortality and morbidity. Two third of patients with ORCC can be managed with resection and primary anastomosis. For high-risk patients, a staged surgical management may be discussed.

PURPOSE: To evaluate efficacy and safety of superior rectal artery embolization of hemorrhoidal disease as a first-line invasive treatment. MATERIALS AND METHODS: This prospective study was conducted between 2014 and 2015 on 25 consecutive patients (16 men and 9 women with a mean age of 53 y [range, 30-76 y]) with grade II-III hemorrhoids refractory to medical treatment. A transfemoral superselective superior rectal artery branch embolization was performed using 2- and 3-mm diameter microcoils. Over the following 12 months, clinical outcomes were evaluated using the French bleeding score, Goligher prolapse score, visual analog scale (VAS) score for pain, quality-of-life score. The primary endpoint was relief of symptoms by 12 months based on a 2-point minimum improvement on VAS score and bleeding score. RESULTS: At 12 months after embolization, clinical success was obtained in 18 patients (72%), 8 of whom had 2 embolizations. VAS score decreased from 4.6 to 2.3 (P < .01), and bleeding score decreased from 5.5 to 2.3 (P < .01). Quality-of-life and prolapse scores also showed improvement (P < .05), and no patients experienced any early or late complications. Complete clinical failure was observed in 7 patients. After coil embolization, the collateral supply to the hemorrhoidal cushions was significantly related to any recurrence (P = .001). CONCLUSIONS: Hemorrhoidal artery coil embolization was found to be a safe and effective treatment for grade II-III hemorrhoids.

PURPOSE: Little is presently known on the impact of device type for Doppler-guided hemorrhoidal artery ligation/mucopexy (DGHAL) or circular stapled hemorrhoidopexy (CSH) when a surgical treatment is considered for hemorrhoidal disease (HD). In this study, we aimed to compare the outcome in terms of adverse events and recurrence rate, of patients included in the multicenter LigaLongo RCT ( ClinicalTrials.gov NCT01240772) according to the type of devices used. METHODS: In the DGHAL arm (N = 193), the procedure was done with transanal hemorrhoidal dearterialization (THD)™ (THD, Correggio, Italy) (104 patients) and with HAL-RAR™ (Agency for Medical Innovations (AMI) GmbH, Feldkirch, Austria) (89 patients). In the CSH arm (N = 184), procedure for prolapse and hemorrhoids (PPH)-03™ (Ethicon Endo-Surgery, Cincinnati OH) and hemorrhoidopexy and prolapse (HEM)™ (Covidien, Inc.) staplers were used in respectively 106 and 78 cases. Surgery-related morbidity at 90 postoperative days (POD) based on the Clavien-Dindo procedure-related complication score and clinical outcome in terms of recurrence and reoperation rate at 12 postoperative months (POM) was collected. RESULTS: Three hundred and seventy-seven patients were randomized according to HD grade. In the DGHAL arm, the number of ligations and mucopexies was higher in the AMI group (p < 0.0001); at 90 POD, the overall morbidity was similar between the two groups. In the CSH arm, donut sizes were similar; at 90 POD, the PPH group had a higher risk of postoperative grade 1 morbidity (anal urgency or incontinence) compared to the HEM group (p = 0.003). At 12 POM, no statistical difference was found between the two groups of each arm in terms of grade III recurrence or reoperation. CONCLUSION: Postoperative morbidity and outcome at 1 year were similar regardless of the type of devices used. These findings suggest that device type has little impact on HD treatment results. TRIAL REGISTRATION: clinicaltrials.gov -Identifier NCT01240772.

BACKGROUND: Brain metastases (BMs) are the most common intracranial neoplasms in adults, but they rarely arise from colorectal cancer (CRC). The objective of this study was to report an overview of the characteristics and current management of CRC BMs. METHODS: A systematic review on CRC BMs was performed using Medline database from 1983 to 2015. The search was limited to studies published in English. Review articles, not relevant case report or studies or studies relating to animal and in vitro experiments were excluded. RESULTS: BMs occurred in 0.06-4% of patients with CRC. Most BMs were metachronous and were associated with lung (27-92%) and liver (12-80%) metastases. Treatment options depended on the number of BMs, the general conditions of the patient and the presence of other metastases. Most frequent treatment was whole-brain radiotherapy (WBRT) alone (36%), with median overall survival comprised between 2 and 9 months. Median overall survival was better after surgery alone (from 3 to 16.2 months), or combined with WBRT (from 7.6 to 14 months). After stereotactic radiosurgery alone, overall survival could reach 9.5 months. Many favourable prognostic factors were identified, such as high Karnofsky performance status, low recursive partitioning analysis classes, lack of extracranial disease, low number of BMs and possibility to perform surgical treatment. CONCLUSION: BMs from CRC are rare. In the presence of favourable prognostic factors, an aggressive management including surgical resection with or without WBRT or stereotactic radiosurgery can improve the overall survival.

BACKGROUND: Microparticles (MPs) are plasma membrane-derived extracellular vesicles present in the bloodstream. We have described a specific signature of MPs, called microparticulosome, in colorectal (CRC) and pancreatic (PC) cancers. We observed that levels of fibrin-bearing MPs were significantly increased in patients suffering from PC and CRC in comparison with control groups. Here, we hypothesised that fibrin-MPs may constitute a relevant biomarker of thrombosis associated with cancer. The objective was to compare the microparticulosome signature between patients presenting with thrombo-embolic event and those without. METHODS: Patients with CRC and PC were prospectively included and divided in those with thrombo-embolic events (Group A) and those without (Group B).MPs were analyzed by flow cytometer, combining the analysis of Annexin V-positive with characterization of their origin and determination of their procoagulant activities. D-dimer levels were measured in the same samples. RESULTS: We included 118 patients, divided in 19 patients with thrombo embolic event and 99 patients without. Fibrin-bearing MPs levels were significantly higher in presence of thrombo-embolic events, contrary to D-dimers levels. Fibrin-bearing MPs were more frequently produced by erythrocytes, endothelial cells or Ep-CAM+cells than platelets or leukocytes. Overall survival was shorter in case of thrombo-embolic events than without. The most frequent genes expressed by MPs derived from PC or CRC were implicated in metastatic diffusion of tumor cells, drug resistance, coagulation and inflammation. CONCLUSION: Circulating MPs, particularly fibrin-bearing MPs, could be used as a new biomarker to predict cancer-associated thrombo-embolic events and poor survival.
RESUMEN
BACKGROUND: About 25% of patients with acute diverticulitis require emergency intervention. Currently, most patients with diverticular peritonitis undergo a Hartmann's procedure. Our objective was to assess whether primary anastomosis (PA) with a diverting stoma results in lower mortality rates than Hartmann's procedure (HP) in patients with diverticular peritonitis. STUDY DESIGN: We conducted a multicenter randomized controlled trial conducted between June 2008 and May 2012: the DIVERTI (Primary vs Secondary Anastomosis for Hinchey Stage III-IV Diverticulitis) trial. Follow-up duration was up to 18 months. A random sample of 102 eligible participants with purulent or fecal diverticular peritonitis from tertiary care referral centers and associated centers in France were equally randomized to either a PA arm or to an HP arm. Data were analyzed on an intention-to-treat basis. The primary end point was mortality rate at 18 months. Secondary outcomes were postoperative complications, operative time, length of hospital stay, rate of definitive stoma, and morbidity. RESULTS: All 102 patients enrolled were comparable for age (p = 0.4453), sex (p = 0.2347), Hinchey stage III vs IV (p = 0.2347), and Mannheim Peritonitis Index (p = 0.0606). Overall mortality did not differ significantly between HP (7.7%) and PA (4%) (p = 0.4233). Morbidity for both resection and stoma reversal operations were comparable (39% in the HP arm vs 44% in the PA arm; p = 0.4233). At 18 months, 96% of PA patients and 65% of HP patients had a stoma reversal (p = 0.0001). CONCLUSIONS: Although mortality was similar in both arms, the rate of stoma reversal was significantly higher in the PA arm. This trial provides additional evidence in favor of PA with diverting ileostomy over HP in patients with diverticular peritonitis. ClinicalTrials.gov Identifier: NCT 00692393.

PURPOSE: This work aimed to analyse short- and long-term results of enterocele surgical treatment by ventral rectopexy. METHODS: All females who underwent ventral rectopexy for enterocele in our department were included. All patients underwent standardized preoperative evaluation. Data was retrospectively collected, after examination of patients or by telephone survey. Postoperative evaluation was performed by an independent observer. RESULTS: One hundred thirty-eight females (median age = 63 years [21-86 years]) were included. They were postmenopausal and multiparous in 94 and 70% of cases, respectively. Pelvic pressure, vaginal prolapse, or the both were observed in 28, 16 or 56% of the patients, respectively. The most frequent associated symptoms were dyschezia (63%) and faecal incontinence (30%). On preoperative workup, enterocele was isolated in two cases. Rectocele, internal rectal prolapse and cervicocystoptosis were the most frequently associated pelvic floor disorders. Ventral rectopexy was performed through laparoscopy in 128 patients (93%). In the short term, all pelvic symptoms were significantly improved, except urinary incontinence. At the end of follow-up (56 months [7-125]), specific symptoms and dyschezia were still significantly improved. Secondary failure was reported in 31% of patients. By multivariate analysis, two predictive factors for long-term failure were found: diagnosis of rectocele on preoperative MRI (odd ratio = 15; 95% CI 1.4-163; p = 0.03) and conversion into open surgery (odd ratio = 8; 95% CI 1.4-43; p = 0.02). CONCLUSION: This study suggests that ventral rectopexy is an effective treatment of enterocele, but secondary failure can be observed. Patients should be informed of the potential risk of long-term degradation.

BACKGROUND: The efficacy and safety of treating elderly patients with colorectal cancer (CRC) is of concern. This study aimed to compare the short- and long-term outcomes of elective laparoscopic vs. open surgery to treat CRC in very elderly patients. METHODS: All patients aged >80 years and who had undergone a colectomy for CRC without metastasis between July 2005 and April 2012 were considered for inclusion. Demographic, clinical, operative, and postoperative data, plus overall and disease-free survival rates, were retrospectively collected and compared between two groups of patients that underwent an open procedure (OP group) or laparoscopy (LG). RESULTS: 123 patients were enrolled (55 OPG, 68 LG). Median age was similar between the groups (84 vs. 83 years, respectively; NS). Duration of surgery was significantly lower in OPG (170 vs. 200min; p=0.030). Overall mortality at 3 months was 8.3%: it tended to be greater in the OPG (16.5% vs. 1.5%, NS). Morbidity was significantly greater in the OPG compared to the LG (52.7% vs. 27.5%; p=0.021), resulting in significantly longer hospital stay (12 vs. 8 days, respectively; p<0.001). Pathological findings were similar between the two groups. Cumulative overall survival rates at 3 and 5 years were significantly greater after laparoscopy (85% and 72%) compared to open surgery (58.2% and 48%, respectively; p<0.001). CONCLUSIONS: Our study suggests that laparoscopy is safe and could increase overall survival compared to open surgery in elderly patients suffering from CRC. SUMMARY: This retrospective study compared the short- and longer-term outcomes of patients aged >80 years and undergoing elective laparoscopic or open surgery for CRC between 2005 and 2012.
