OBJECTIVE:Several cases of pancreatitis have been described during the course of Crohns disease (CD) or ulcerative colitis (UC), but many of them were related to either biliary lithiasis or drug intake. We tried to evaluate the clinical and morphological features of so-called idiopathic pancreatitis associated with inflammatory bowel disease and to define their pathological characteristics.METHODS:Chronic idiopathic pancreatitis was diagnosed on the basis of abnormal pancreatograms suggestive of chronic pancreatitis associated with or without impaired exocrine pancreatic function, or pathological examination in patients undergoing pancreatic resection. We found 6 patients presenting with features of chronic idiopathic pancreatitis and UC and 2 patients with CD seen between 1981 and 1996 in three hospital centers of the south of France. A review of the literature has identified 6 cases of pancreatitis associated with UC and 14 cases of pancreatitis associated with CD based on the above criteria.RESULTS:Hyperamylasemia was not a sensitive test since it was present in 44% and 64% of patients with UC or CD. In UC, pancreatitis was a prior manifestation in 58% of patients. In contrast, the pancreatitis appeared after the onset of CD in 56% of the cases. In patients with UC, pancreatitis were associated with severe disease revealed by pancolitis (42%) and subsequent surgery. Bile duct involvement was more frequent in patients with UC than with CD (58%vs 12%) mostly in the absence of sclerosing cholangitis (16%vs 6%). Weight loss and pancreatic duct stenosis were also more frequent in UC than in CD (41%vs 12% and 50%vs 23%, respectively). Pathological specimens were analyzed in 5 patients and demonstrated the presence of inter- and intralobular fibrosis with marked acinar regression in 3 and the presence of granulomas in 2 patients, both with CD.CONCLUSIONS:Pancreatitis is a rare extraintestinal manifestation of inflammatory bowel disease. Chronic pancreatitis associated with UC differs from that observed in CD by the presence of more frequent bile duct involvement, weight loss, and pancreatic duct stenosis, possibly giving a pseudo-tumor pattern.

BACKGROUND Endoscopic procedures have become a first-line approach to the treatment of pancreatic pseudocysts. OBJECTIVE Our purpose was to determine the results of a therapeutic algorithm including EUS-assisted drainage, transpapillary drainage, and conventional endoscopic drainage in terms of (1) feasibility and efficacy of the endoscopic procedure and (2) morbidity. DESIGN Prospective study with a treatment algorithm drawn up before the endoscopic procedure, including either conventional endoscopic transmural drainage (CTMD), conventional transpapillary drainage (CTPD), or EUS-guided transmural drainage (EUS-GTD). PATIENTS A total of 50 patients, including 15 women and 35 men with a mean age of 51 years, were included in this prospective study. RESULTS The mean size of the pseudocysts was 8.2 cm (range 3-12 cm). A total of 29 pseudocysts did not bulge into the digestive wall (58%); 24 (48%) neither bulged nor communicated with the pancreatic duct. EUS-GTD was performed on 28 patients (56%), CTMD on 13 patients (26%), and CTPD on 8 patients (16%), and endoscopic procedures failed in 1 patient. Technical feasibility was 98% (49/50), and clinical success was achieved in 90% of the cases and disappearance of the pseudocysts in 96% of the cases without significant differences among the 3 groups. The morbidity rate was 18% (9 cases). Five superinfections occurred in the EUS-GTD group and 1 in the CTMD group. One death occurred from late bleeding in the CTMD group. LIMITATION Randomization of patients in this prospective study was not possible because of the different characteristics of the pseudocysts. CONCLUSION With this algorithm, clinical success was achieved in 45 (90%) of the cases and disappearance of the pseudocysts in 48 (96%) of the cases with a reasonable morbidity rate. In half of the cases, EUS is required for treating pancreatic pseudocyst.

BACKGROUND Treatment of anastomotic fistulas after bariatric surgery is difficult, and they are often associated with additional surgery, sepsis, and prolonged non-oral feeding. OBJECTIVE To assess a new, totally endoscopic strategy to manage anastomotic fistulas. DESIGN Prospective study. SETTING Tertiary-care university hospital. PATIENTS This study involved 27 consecutive patients from July 2007 to December 2009. INTERVENTION This strategy involved successive procedures for endoscopic drainage of the residual cavity, diversion of the fistula with a stent, and then closure of the residual orifice with surgical clips or sealant. MAIN OUTCOME MEASUREMENTS Technical success, mortality and morbidity, migration of the stent. RESULTS Multiple or complex fistulas were present in 16 cases (59%). Endoscopic drainage (nasal-fistula drain or necrosectomy) was used in 19 cases (70%). Diversion by a covered colorectal stent was used in 22 patients (81%). To close the residual or initial opening, wound clips and glue (cyanoacrylate) were used in 15 cases (55%). Neither mortality nor severe morbidity occurred. Migration of the stent occurred in 13 cases (59%) and was treated by replacement with either a longer stent or with 2 nested stents. The mean time until resolution of fistula was 86 days from the start of endoscopic management, with a mean of 4.4 endoscopies per patient. LIMITATIONS Moderate sample size, nonrandomized study. CONCLUSION An entirely endoscopic approach to the management of anastomosing fistulas that develop after bariatric surgery--using sequential drainage, sutures, and diversion by stents--achieved resolution of the fistulas with minimal morbidity.

In 12 patients suffering from chronic idiopathic anal pain, the rectosphincteric function was studied using manometric and x-ray techniques. The results of manometric investigations were compared with those obtained in 12 healthy volunteers. In all patients, the resting pressure in the anal canal was significantly higher than in control subjects. In 10 patients, defecography revealed abnormalities of the pelvic muscles. We treated the patients by using biofeedback techniques, consisting of voluntary modifications of the state of contraction of the external sphincter. In all cases, pain disappeared after a mean of eight biofeedback training sessions. When noxious manifestations had disappeared, manometry showed a significant decrease in the anal canal resting pressure. Our results indicate 1) that chronic idiopathic anal pain is associated with abnormal anorectal manometric profiles, probably resulting from a dysfunctioning of the striated external anal sphincter, and 2) that biofeedback training is an effective treatment for chronic idiopathic anal pain.

PurposeSacral nerve stimulation is a technique commonly used for the treatment of idiopathic incontinence. This study was designed to assess the efficiency of sacral nerve stimulation as a means of treating fecal incontinence in patients with Crohn’s disease with disrupted internal and external anal sphincters.MethodsFive patients (3 women) with fecal incontinence suffering from Crohn’s disease-related anoperineal lesions were treated by applying three weeks of sacral nerve stimulation and then by permanent sacral nerve stimulation implantation. Endoanal ultrasonography showed that all of these patients had disrupted external and internal anal sphincters.ResultsContinence was improved in all treated patients. The median follow-up time was 14 (range, 3–36) months. At the end of the follow-up period, the median Wexner’s score significantly improved from 15 to 6 and the median number of daily stools decreased from 7 to 2. The patients’ quality of life also increased significantly.ConclusionsSacral nerve stimulation improves fecal continence in patients suffering from Crohn’s anoperineal lesions with internal and external anal sphincters disruption.

BACKGROUND: Pelvic floor disorders are frequent, especially in women. Surgeons need more information on the accuracy of available diagnostic techniques to make therapeutic decisions. OBJECTIVE: This study aimed to compare the accuracy of dynamic anorectal endosonography and dynamic MRI defecography with conventional defecography as the criterion standard in the diagnosis of pelvic floor disorders. DESIGN: We used a prospective crossover design in which patients underwent each procedure in random order within the same month. SETTING: Investigations were conducted at a regional referral center in Marseille, France. PATIENTS: Women with dyschezia who were undergoing diagnostic evaluation were eligible. INTERVENTION: Dynamic anorectal endosonography, dynamic MRI, and conventional defecography were performed in all patients by 3 blinded operators. MAIN OUTCOME MEASURE: The accuracy of dynamic anorectal endosonography and dynamic MRI in the diagnosis of pelvic floor disorders was assessed by calculating sensitivity, specificity, positive and negative predictive values, correlation coefficients, concordance rates, and the Cohen &kgr; statistic, with conventional defecography used as the criterion standard. RESULTS: The study comprised 56 women with a mean age of 50.7 (SD, 12.5) years. No significant differences were observed between dynamic anorectal endosonography and dynamic MRI in the number of patients with rectocele (P = .49), perineal descent (P = .11 when dynamic anorectal endosonography measured descent of the puborectalis muscle; P = .27 for bladder descent), or enterocele (P = .78); no differences were found between these techniques in sensitivity, specificity, or positive and negative predictive values. Diagnostic concordance with conventional defecography as the standard did not differ significantly between dynamic MRI and dynamic anorectal endosonography: Concordance rates for dynamic anorectal endosonography were 75% for rectocele, 64% for perineal descent, and 91% for enterocele (no rectal intussusception was found with dynamic anorectal endosonography); concordance rates for dynamic MRI were 82% for rectocele, 57% for perineal descent, 93% for enterocele, and 55% for rectal intussusception. Significantly more internal anal sphincter defects were found with dynamic anorectal endosonography than with dynamic MRI defecography: 21 patients (37.5%) vs 12 patients (21.4%); P = .02. Patient tolerance was significantly better for dynamic anorectal endosonography than for dynamic MRI (P = .002) or conventional defecography (P = .005). Most patients said they would choose dynamic anorectal endosonography (72.1%) rather than dynamic MRI (25.6%) or conventional defecography (2.3%) if follow-up were necessary (P < .001). CONCLUSION: Dynamic anorectal endosonography and dynamic MRI defecography show equivalent diagnostic performance in assessing pelvic floor disorders. However, because of its better tolerance and availability, dynamic anorectal endosonography may be preferable as the initial imaging procedure after clinical examination in the evaluation of pelvic floor disorders.

Background and Aims: Clinical symptoms of inflammatory bowel disease (IBD)-associated pancreatitis are found in ∼2% of patients, but the frequency of the disease could be much higher since IBD-associated pancreatitis could be mainly a silent disease. The aim of this study was to describe the radiological and biological features of IBD-associated pancreatitis and assess its frequency by comparing data from IBD patients with or without a history of pancreatitis. Methods: 79 patients were prospectively enrolled (median age 36 years). Symptoms of pancreatitis had been previously recorded in 30 of them (group P; the other 49 patients (group C) had no history of pancreatitis. Pancreatic ductal changes were investigated by pancreato-MRI. Exocrine function was assessed by the fecal elastase test and by assaying serum amylase, lipase, C-reactive protein, PAP, IgG4 and pancreatic autoantibodies. Results: Increased levels of amylase and lipase occurred in 11% of IBD patients, that frequency being significantly higher in group P (23%) than in group C (4%) (p = 0.01). Low fecal elastase reflecting impaired exocrine function was observed in 30% of patients and again significantly more in group P (50%) than in group C (17%) (p = 0.04). The frequency of elevated values varied from 12% for amylase and lipase to 18% for PAP, 20% for pancreatic autoantibodies and 45% for CRP, without a difference between groups P and C. Silent exocrinopathy was observed in both groups, pancreatic autoantibodies and pancreatic duct alterations being found in 20 and 11% of patients, respectively. Conclusion: Finding pancreatic insufficiency in about 30% of the included patients and in 50% of those with a previous history of pancreatitis suggests that IBD might be associated with chronic pancreatic alteration. Episodes of mild acute pancreatitis observed in some patients are not always due to adverse effects of treatments and can be acute manifestations of the chronic disease.
