Crohn's disease is a relapsing systemic inflammatory disease, mainly affecting the gastrointestinal tract with extraintestinal manifestations and associated immune disorders. Genome wide association studies identified susceptibility loci that--triggered by environmental factors--result in a disturbed innate (ie, disturbed intestinal barrier, Paneth cell dysfunction, endoplasmic reticulum stress, defective unfolded protein response and autophagy, impaired recognition of microbes by pattern recognition receptors, such as nucleotide binding domain and Toll like receptors on dendritic cells and macrophages) and adaptive (ie, imbalance of effector and regulatory T cells and cytokines, migration and retention of leukocytes) immune response towards a diminished diversity of commensal microbiota. We discuss the epidemiology, immunobiology, amd natural history of Crohn's disease; describe new treatment goals and risk stratification of patients; and provide an evidence based rational approach to diagnosis (ie, work-up algorithm, new imaging methods [ie, enhanced endoscopy, ultrasound, MRI and CT] and biomarkers), management, evolving therapeutic targets (ie, integrins, chemokine receptors, cell-based and stem-cell-based therapies), prevention, and surveillance.
We reviewed the final diagnosis and incidence of bowel pathology in neonates presenting with large bowel obstruction that was relieved by the passage of meconium plugs. A retrospective case-note review was undertaken of all patients with a discharge diagnosis of meconium plug syndrome (MPS), meconium ileus (MI), Hirschsprung's disease (HD), or small left colon syndrome (SLCS) from January 1996 to April 2002. Of 21 patients with meconium plug obstruction, eight (38%) had HD, nine had MPS, four had SLCS, and none had MI. However, there was considerable clinical and radiological overlap between MPS and SLCS, suggesting that these terms are imprecise. We found a much higher incidence of HD in babies presenting with meconium plug obstruction than has previously been reported. Overlap between MPS and SLCS suggests that these are not specific diagnoses and that current terminology needs to be changed. All babies with meconium plug obstruction should have HD and cystic fibrosis (CF) excluded.
Empyemas developing after traumatic rupture of intraabdominal organs have been previously reported. We report a case of a true nontraumatic colopleural fistula following surgery for spontaneous rupture of a sigmoid diverticulum. The diagnosis was suspected by the presence of an air-containing tract seen in a computerized tomogram of chest and abdomen and was established with a contrast study. The empyema cavity was initially drained, followed by a laparotomy and fistulectomy with primary large bowel anastomosis and loop ileostomy. Although rare, colopleural fistulas present a diagnostic challenge and delayed management can lead to increased morbidity.
