Background Crohn’s disease (CD) is considered a contraindication to ileal pouch—anal anastomosis (IPAA). In this study, we compare outcomes of CD and ulcerative colitis (UC) patients undergoing IPAA. Methods Patients were considered to have CD before surgery based on a history of small bowel disease, perianal disease, noncrypt-associated granuloma, or pretreatment skip colonic lesions. Patients were prospectively assessed for pouchitis or CD. Postoperative CD (pouch inflammation into the afferent limb or pouch fistula) or pouch failure (need for permanent diversion) were assessed. Preoperative serum was assayed for IBD-associated antibodies using enzyme-linked immunosorbent assay (ELISA). Results Seventeen patients with preoperative CD were identified. Seven (41%) patients developed postoperative recurrent CD in the afferent limb (n = 3) or pouch fistulizing disease (n = 4). One patient (6%) required pouch excision. The incidence of postoperative CD was higher (P = 0.002) in preoperative CD patients (41%) than UC patients (11%). There was no significant difference in pouchitis or pouch failure. There was also no significant difference in any preoperative clinical feature between patients with or without postoperative CD. Afferent limb inflammation developed in three (50%) of the six patients with pANCA+/OmpC− expression compared to none of the 11 patients without this serologic profile (P = 0.03). Conclusions Although the intentional use of IPAA in CD has a higher incidence of postoperative disease vs. UC patients, there was no significant difference in pouch failure. Demographics, clinical features, and serologic factors do not predict outcome of CD patients undergoing IPAA. IBD serology may identify the phenotype manifestation of postoperative recurrent CD.

IntroductiondClinical and bacteriological features of cobra (Naja) bites are still relatively unknown in Vietnam. This study aimed to characterize the clinical and bacteriological characteristics of local wounds in patients with presumed Naja spp bite, as well as their antibiotic treatment.MethodsdA cross-sectional study was performed on presumed Naja bite patients who were admitted to Bach Mai Hospital in Hanoi, Vietnam. In vitro bacterial isolation, blood tests, and lesion measure were conducted, and antibiotic susceptibilities of localized bite wounds were assessed. The Mann-Whitney test was used to examine the difference in clinical characteristics between patients experiencing presumed Naja atra bites and Naja kaouthia bites. Data are presented as percentages or median with interquartile range, as appropriate. Statistical significance was accepted at P<0.05.ResultsdAmong 46 patients, all had typical clinical features of Naja bite. The median bite-to-hospital time was 6 h (interquartile range 4.0e11.3). The dominant organisms isolated from local wounds were Morganella morganii (11/36) and Enterococcus faecalis (25/36). All cultures were susceptible to ciprofloxacin. No difference was found with regard to pain, swelling circumference, swelling spread, or necrotic area between patients bitten by presumed Naja atra and Naja kaouthia (P>0.05).ConclusionsdWound necrosis and infection were important clinical issues in presumed Naja spp snake bites. Morganella morganii and Enterococcus faecalis were dominant in local wound swabs of such cases. Ciprofloxacin should be an effective first-line antibiotic for patients with presumed Naja bite.

POI is difficult to predict after first- and second-stage IPAA. Clinical factors and a history of POI from first-stage IPAA do not predict POI after second-stage IPAA. Patients with a history of POI after STC do not have an increased risk of developing recurrent POI.
