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.

Penetrating Crohn Disease Is Not Associated With a Higher Risk of Recurrence After Surgery: A Prospective Nationwide Cohort Conducted by the Getaid Chirurgie Group.

OBJECTIVE: The aim of this study was to assess recurrence risk factors following ileocolonic resection (ICR) for Crohn disease (CD) in a nationwide cohort study SUMMARY BACKGROUND DATA:: Recurrence rate after ICR for CD can be up to 60%, but its predictive factors have never been evaluated in large prospective cohort studies. METHODS: From 2013 to 2015, 346 consecutive patients undergoing ICR for CD and a postoperative ileocoloscopy within 6 to 12 months after surgery at 19 academic French centers were included prospectively. RESULTS: Twelve-month postoperative endoscopic (Rutgeerts score ≥i2) and clinical recurrence rates were 57.6% [95% confidence interval (CI), 54.2-61.0] and 11.3% (95% CI, 9-13.6), respectively. A total of 185 patients (54%) had a postoperative CD prophylaxis, comprising thiopurine in 69 (20%), or anti-tumor necrosis factor (TNF) therapy in 93 (27%). In multivariate Cox regression analysis, absence of postoperative smoking {odds ratio [OR] = 0.60 (95% CI, 0.40-0.91); P = 0.016}, postoperative prophylaxis [OR = 0.60 (95% CI, 0.41-0.88); P = 0.009], and penetrating disease behavior [OR = 0.58 (95% CI, 0.39-0.86); P = 0.007] were the only independent predictors of reduced endoscopic recurrence risk. Postoperative prophylaxis [OR 0.31 (95% CI, 0.15-0.66); P = 0.002), and penetrating behavior [OR = 00.36 (95% CI, 0.16-0.81); P = 0.013), were the only independent predictors of reduced clinical recurrence risk. Postoperative anti-TNF therapy was associated with a significant reduction of both 12-month risks of endoscopic (P < 0.001) and clinical (P = 0.019) recurrences. CONCLUSION: Absence of postoperative smoking, CD prophylaxis, and penetrating disease behavior could be independent predictors of reduced postoperative recurrence after ICR for CD. Prophylactic anti-TNF therapy reduces both endoscopic and clinical recurrence rates. It suggests that upfront surgery followed by postoperative anti-TNF therapy is probably the best therapeutic approach for complex CD (penetrating disease behavior).

Anti-TNF Therapy Is Associated With an Increased Risk of Postoperative Morbidity After Surgery for Ileocolonic Crohn Disease: Results of a Prospective Nationwide Cohort.

OBJECTIVE: To determine the risk factors of morbidity after surgery for ileocolonic Crohn disease (CD). SUMMARY BACKGROUND DATA: The risk factors of morbidity after surgery for CD, particularly the role of anti-TNF therapy, remain controversial and have not been evaluated in a large prospective cohort study. METHODS: From 2013 to 2015, data on 592 consecutive patients who underwent surgery for CD in 19 French specialty centers were collected prospectively. Possible relationships between anti-TNF and postoperative overall morbidity were tested by univariate and multivariate analyses. Because treatment by anti-TNF is possibly dependent on the characteristics of the patients and disease, a propensity score was calculated and introduced in the analyses using adjustment of the inverse probability of treatment-weighted method. RESULTS: Postoperative mortality, overall and intra-abdominal septic morbidity rates in the entire cohort were 0%, 29.7%, and 8.4%, respectively; 143 (24.1%) patients had received anti-TNF <3 months prior to surgery. In the multivariate analysis, anti-TNF <3 months prior to surgery was identified as an independent risk factor of the overall postoperative morbidity (odds-ratio [OR] =1.99; confidence interval [CI] 95% = 1.17-3.39, P = 0.011), with preoperative hemoglobin <10 g/dL (OR = 4.77; CI 95% = 1.32-17.35, P = 0.017), operative time >180 min (OR = 2.71; CI 95% = 1.54-4.78, P < 0.001) and recurrent CD (OR = 1.99; CI 95% = 1.13-3.36, P = 0.017). After calculating the propensity score and adjustment according to the inverse probability of treatment-weighted method, anti-TNF <3 months prior to surgery remained associated with a higher risk of overall (OR = 2.98; CI 95% = 2.04-4.35, P <0.0001) and intra-abdominal septic postoperative morbidities (OR = 2.22; CI 95% = 1.22-4.04, P = 0.009). CONCLUSIONS: Preoperative anti-TNF therapy is associated with a higher risk of morbidity after surgery for ileocolonic CD. This information should be considered in the surgical management of these patients, particularly with regard to the preoperative preparation and indication of temporary defunctioning stoma.

Morbidity, mortality, and oncological outcomes of 401 consecutive cytoreductive procedures with hyperthermic intraperitoneal chemotherapy (HIPEC).

PURPOSE: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are a novel curative treatment option for selected patients with peritoneal carcinomatosis (PC). We aimed to report the mortality rate and the most frequent grade III-IV adverse events and to identify associated prognostic markers. We report oncological outcomes and major prognostic factors influencing overall survival (OS) and disease-free survival. METHODS: A total of 401 CRS plus HIPEC procedures were performed on 356 patients. Mortality, grade III-IV adverse events, OS, disease-free survival, and prognostic factors were studied. RESULTS: Based on Common Terminology Criteria for Adverse Events (CTCAE of the National Cancer Institute 2006), mortality rate was 1 % and overall rate of morbidity grade III-IV was 12.5 %. In multivariate analysis, only the number of digestive anastomoses (>1) significantly correlated with adverse events with an odds ratio of 2.8 (p = 0.032). OS was related to histological type of PC, with a median survival reaching 47.6 months for PC of ovarian cancer origin, 45.8 months for that of colorectal origin, 64.2 months for peritoneal mesothelioma, and 8.1 months for PC of gastric cancer origin. Over half the patients with pseudomyxoma are still alive. Major prognostic factors influencing survival were histological type, World Health Organization performance status (WHO PS) (hazard ratio (HR) = 3.56), operating time (HR = 0.45), previous chemotherapy (HR = 2.04), number of peritonectomies (HR = 2.03), and completeness of cytoreduction score (HR = 3.12). Disease-free survival across all groups was 16.8 months. CONCLUSION: The low mortality rate and 12.5 % grade III-IV morbidity of CRS and HIPEC are acceptable when weighed against overall oncologic survival. This multimodal treatment appears feasible for selected patients and trained centers.

Post-traumatic transdiaphragmatic intercostal hernia: report of two cases.

Transdiaphragmatic intercostal hernias (TIH) are rare. Less than 40 cases of TIH have so far been reported, with only 8 cases involving herniation of the liver. This report presents the case of 2 patients with a right-sided abdominal lump following a fall. Thoracoabdominal CT-scan showed a TIH between the 9th and 10th ribs with liver and right colonic herniation in both patients. Both patients were successfully treated with mesh repair. The presentation, physiopathology and management of this rare occurrence are discussed.

Additional colectomy after colonoscopic polypectomy for T1 colon cancer: a fine balance between oncologic benefit and operative risk.

PURPOSE: The treatment of early-stage colorectal cancers removed endoscopically depends on histopathologic findings. This study aimed to assess the benefit-risk balance for patients who underwent additional surgery after endoscopic resection of a T1 carcinoma with unfavorable histology. METHODS: From 2000 to 2010, 64 consecutive patients were included in this retrospective study. Specimens resected after endoscopic polypectomy showed at least one of the following unfavorable factors: no free margin, lymphovascular invasion, poorly differentiated grade, SM2-3 involvement (submucosal invasion greater than 300 µm from the muscularis mucosae), tumor budding, sessile morphology, and piecemeal resection. The main objective was to assess the benefit-risk balance of an oncological resection performed after the polypectomy. Oncological benefit was measured by the lymph node metastasis rate and the persistence of a residual adenocarcinoma on the specimen. The risk was measured by the occurrence of severe complications of grade III-IV or death. The associations between these end points and clinicopathologic variables were evaluated by univariate analysis and logistic regression. RESULTS: Five patients (7.8 %) had lymph node metastases and two (3.1 %) had residual carcinomas. Eight patients (12.5 %) had grade III-IV morbidity. There were no deaths. Oncological benefit was associated by logistic regression analysis with patients who presented multiple criteria (≥2) that led to surgery (p = 0.031). The benefit-risk balance was favorable only for those patients. CONCLUSIONS: Additional surgery is required for patients who present multiple adverse histological criteria. If only one criterion is selected, the indication should be discussed, especially for patients with multiple comorbidities.

The role of clips in preventing migration of fully covered metallic esophageal stents: a pilot comparative study.

BACKGROUND: Migration is the most common complication of the fully covered metallic self-expanding esophageal stent (SEMS). This study aimed to determine the potential preventive effect of proximal fixation on the mucosa by clips for patients treated with fully covered SEMS. METHODS: In this study, 44 patients (25 males, 57%) were treated with fully covered SEMS including 22 patients with esophageal stricture (4 malignant obstructions, 6 anastomotic strictures, and 12 peptic strictures) and 22 patients with fistulas or perforations (10 anastomotic leaks, 4 perforations, and 8 postbariatric surgery fistulas). The Hanarostent (n = 25), Bonastent (n = 5), Niti-S (n = 12), and HV-stent (n = 2) with diameters of 18 to 22 mm and lengths of 80 to 170 mm were used. Two to four clips (mean, 2.35 ± 0.75 clips) were used consecutively in 23 patients to fix the upper flared end of the stent with the esophageal mucosal layer. Stent migration and its consequences were collected in the follow-up assessment with statistical analysis to compare the patients with and without clip placement. RESULTS: No complication with clip placement was observed, and the retrieval of the stent was not unsettled by the persistence of at least one clip (12 cases). Stent migration was noted in 15 patients (34%) but in only in 3 of the 23 patients with clips (13%). The number of patients treated to prevent one stent migration was 2.23. The predictive positive value of nonmigration after placement of the clip was 87%. In the multivariate analysis, the fixation with clips was the unique independent factor for the prevention of stent migration (odds ratio, 2.3; 95% confidence interval, 0.10-0.01; p = 0.03). CONCLUSIONS: Anchoring of the upper flare of the fully covered SEMS with the endoscopic clip is feasible and significantly reduces stent migration.

Small bowel involvement is a prognostic factor in colorectal carcinomatosis treated with complete cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy.

BACKGROUND: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) is a promising treatment for patients with peritoneal carcinomatosis (PC). Our objective was to identify new prognostic factors in patients with PC from colorectal cancer treated with this procedure. METHODS: All patients with PC from colorectal cancer treated by HIPEC from January 2000 to December 2007 were prospectively included. The tumor extension was assessed by the Peritoneal Cancer Index (PCI) and the residual disease was recorded using the completeness cytoreductive score (CCs). All clinical and treatment data were computed in univariate and multivariable analyses using survival as primary end point. RESULTS: We carried out 51 complete procedures in 49 consecutive patients. The mean PCI was 10. The allocation of CCs was: CC-0 = 37, CC-1 = 14. The five-year overall and progression-free survival rate were 40% and 20%, respectively. Several prognostic factors for survival were identified by univariate analysis: PCI < 9 (P < 0.001), CC-0 vs. CC-1 (P < 0.01) and involvement of area 4 (P = 0.06), area 5 (P = 0.031), area 7 (P = 0.014), area 8 (P = 0.022), area 10 (P < 0.0001), and area 11 (P = 0.02). Only the involvement of the distal jejunum (area 10) was significant in the multivariable analysis (P = 0.027). CONCLUSIONS: We demonstrated that the involvement of area 10 (distal jejunum of the PCI score) was an independent factor associated with poor prognosis.

Impact of the Ileal Microbiota on Surgical Site Infections in Crohn's Disease: A Nationwide Prospective Cohort.

BACKGROUND AND AIMS: Surgery is performed in 50-70% of Crohn's disease [CD] patients, and its main risk is surgical site infection [SSI]. The microbiota has been extensively assessed in CD but not as a potential risk factor for septic morbidity. The objective of this study was to assess the impact of the gut microbiota on SSI in CD. METHODS: We used the multicentric REMIND prospective cohort to identify all patients who experienced SSI after ileocolonic resection for CD, defined as any postoperative local septic complication within 90 days after surgery: wound abscess, intra-abdominal collection, anastomotic leakage or enterocutaneous fistula. The mucosa-associated microbiota of the ileal resection specimen was analysed by 16S gene sequencing in 149 patients. The variable selection and prediction were performed with random forests [R package VSURF] on clinical and microbiotal data. The criterion of performance that we considered was the area under the Receiver Operating Characteristic [ROC] curve [AUC]. RESULTS: SSI occurred in 24 patients [16.1%], including 15 patients [10.1%] with major morbidity. There were no significant differences between patients with or without SSI regarding alpha and beta diversity. The top selected variables for the prediction of SSI were all microbiota-related. The maximum AUC [0.796] was obtained with a model including 14 genera, but an AUC of 0.78 had already been obtained with a model including only six genera [Hungatella, Epulopiscium, Fusobacterium, Ruminococcaceae_ucg_009, Actinomyces and Ralstonia]. CONCLUSION: The gut microbiota has the potential to predict SSI after ileocolonic resection for CD. It might play a role in this frequent postoperative complication.

Postoperative Morbidity After Iterative Ileocolonic Resection for Crohn's Disease: Should we be Worried? A Prospective Multicentric Cohort Study of the GETAID Chirurgie.

BACKGROUND AND AIMS: To compare perioperative characteristics and outcomes between primary ileocolonic resection [PICR] and iterative ileocolic resection [IICR] for Crohn's disease [CD]. METHODS: From 2013 to 2015, 567 patients undergoing ileocolonic resection were prospectively included in 19 centres of the GETAID chirurgie group. Perioperative characteristics and postoperative results of both groups [431 PICR, 136 IICR] were compared. Uni- and multivariate analyses of the risk factors of overall 30-day postoperative morbidity was carried out in the IICR group. RESULTS: IICR patients were less likely to be malnourished [27.2% vs 39.9%, p = 0.007], and had more stricturing forms [69.1% vs 54.3%, p = 0.002] and less perforating disease [19.9% vs 39.2%, p < 0.001]. Laparoscopy was less commonly used in IICR [45.6% vs 84.5%, p < 0.01] and was associated with increased conversion rates [27.4% vs 14.6%, p = 0.012]. Overall postoperative morbidity was 36.8% in the IICR group and 26.7% in the PICR group [p = 0.024]. There was no significant difference between IICR and PICR regarding septic intra-abdominal complications, anastomotic leakage [8.8% vs 8.4%] or temporary stoma requirement. IICR patients were more likely to present with non-infectious complications and ileus [11.8% vs 3.7%, p < 0.001]. Uni- and multivariate analyses did not identify specific risk factors of overall postoperative morbidity in the IICR group. CONCLUSIONS: Surgery for recurrent CD is associated with a slight increase of non-infectious morbidity [postoperative ileus] that mainly reflects the technical difficulties of these procedures. However, IICR remains a safe therapeutic option in patients with recurrent CD because severe morbidity including anastomotic complications is similar to patients undergoing primary resection.

[Spontaneous rupture of the spleen in chronic calcifying pancreatitis: report of three cases]. / Rupture spontanée de rate sur pancréatite chronique calcifiante.

Spontaneous rupture of the spleen is a rare complication of chronic calcifying pancreatitis. Anemia and hemorrhagic shock may not occur, making diagnosis more difficult. Favourable response to conservative treatment does not prevent the need for splenectomy, as calcifiying chronic pancreatitis may progress locally. We report three cases of spontaneous rupture of the spleen. In two cases, splenic rupture revealed calcifying chronic pancreatitis and both patients underwent urgent splenectomy. In the third case, the patient was known to have calcifying chronic pancreatitis, and splenectomy was performed because of unsuccessful conservative treatment. We discuss the role of distal pancreatectomy during splenectomy to reduce the rate of postoperative complications and additional surgery. We also discuss the role of arterial embolisation and laparoscopy in the management of this rare condition.

Gemcitabine combined with oxaliplatin is safe and effective in patients with previously untreated advanced pancreatic adenocarcinoma.

AIM: The aim of this study was to determine the safety and the efficacy of a gemcitabine/oxaliplatin combination (GEMOX) as first line therapy in patients with metastatic or unresectable locally-advanced pancreatic cancer. PATIENTS AND METHODS: Patients received gemcitabine 1000 mg/m2 as a 10-mg/m2/min infusion on day 1 followed on day 2 by oxaliplatin 100 mg/m2 as a 2-hour infusion, each cycle being given every 2 weeks. All patients had measurable disease and histological diagnosis before inclusion. Patients were treated until progression or for 12 cycles in the absence of progression. Tumor lesions were assessed by computed tomography scan every 4 cycles. RESULTS: Between January 2001 and January 2003, 32 patients were eligible for the study. The objective response rate (OR) was 28.1% with a 12.5% complete response rate (CR). Median progression-free survival and median overall survival were 7 and 9 months, respectively. Median overall survival for patients with metastatic disease and locally-advanced disease were 7 and 25 months, respectively (P < 0.0007). Eleven patients were alive at 1 year (34.4%), six at 2 years (18.8%) and two at 3 years (6%). Fourteen (43.8%) of 32 patients experienced a clinical benefit response. CONCLUSION: These results support the safety, the antitumor activity and the possibility of durable responses of the GEMOX regimen in patients with locally-advanced disease.

[Cancer of an ectopic pancreas in the duodenal wall]. / Cancer sur pancréas ectopique de la paroi duodénale.

Ectopic pancreas is defined as pancreatic tissue outside the normal location of the pancreas. It can be affected by the same complications as the orthotopic pancreas, such as adenocarcinoma. This extremely rare complication (only 14 published cases) may have a better prognosis that adenocarcinoma of an orthotopic pancreas. Endoscopic ultrasonography may be useful in the diagnosis of this disease. We report a case of malignancy of the duodenal wall originating in aberrant pancreatic tissue, and review the literature.

[Thrombosis of the right ovarian vein]. / Thrombose de la veine ovarienne droite.

INTRODUCTION: Thrombosis of the ovarian vein (TOV) is a rare complication which arises classically in the post-partum. Its main signs are pain in the flanks or the iliac fossa, associated with temperature and hyperleukocytosis. It is a differential diagnosis of acute appendicitis when located on the right side. OBSERVATION: A 26 year-old, primiparous woman consulted at 38 weeks of amenorrhoea for pain in the right iliac fossa and flank with a temperature of 38.6 degrees C. Three days after delivery, because of heavier pain, a coelioscopy was decided on that led to the diagnosis of thrombosis of the right ovarian vein. COMMENTS: Improvement in the diagnosis techniques, notably Doppler ultrasonography and spiral CT should avoid the diagnosis of TOV during surgery. Traditionally a post-partum complication, TOV can occur before delivery, period during which it is very important not to misjudge this diagnosis, notably in case of thrombosis spreading to the inferior vena cava with free-floating thrombus. The treatment of TOV is essentially medical. In the case of extension to the vena cava, the installation of a vena cava filter or a surgical cava thrombectomy may be necessary.

Ascites and malnutrition are predictive factors for incomplete cytoreductive surgery for peritoneal carcinomatosis from gastric cancer.

BACKGROUND: Prognosis in peritoneal carcinomatosis from gastric cancer has improved with cytoreductive surgery (CS) and hyperthermic intraperitoneal chemotherapy. The aim of this study was to identify predictive factors for incomplete CS. METHODS: Forty-five patients undergoing laparotomy for gastric cancer with peritoneal carcinomatosis were prospectively included from January 2000 to December 2010. In case of optimal CS, patients (n = 14) received hyperthermic intraperitoneal chemotherapy. Otherwise, the laparotomy was closed or a palliative procedure was performed if necessary. All preoperative data were compared between the 2 groups. RESULTS: Ascites (hazard ratio, .09; 95% confidence interval, .010-.48; P = .0103) and nutritional status evaluated by the prognostic nutrition index (hazard ratio, .11; 95% confidence interval, .0019-.54; P = .027) were independent predictive factors for incomplete CS. CONCLUSIONS: The selection of patients for CS plus hyperthermic intraperitoneal chemotherapy should include the assessment of nutritional status and the detection of an ascites.

Swallowing a safety pin: Report of a case.

Ingestion of a foreign body is a frequent and well-known medical problem with several diagnostic and therapeutic approaches. Usually, ingested foreign bodies pass through the alimentary tract without incident. In some cases, they can be lodged in the appendix and may cause appendicitis. We report a case of a 29-year old woman, suffering from mental illness, with a safety pin lodged in the appendix. Initially, the patient consulted for abdominal pain. After a period of waiting, during which time the foreign body did not move, a colonoscopy was performed but failed to see the safety pin. Then, the patient underwent a laparoscopic appendectomy. Pathological examination showed an ulcerative appendicitis.
