Synchronous isolated splenic metastasis from colon carcinoma.

&NA; We report the first case known to us of a synchronous isolated splenic metastasis from colon carcinoma in a 52‐year‐old woman operated on splenectomy, left colectomy, and ileal resection. The patient died of diffuse carcinomatosis 1 year after the operation. Splenectomy for isolated splenic metastasis from colon carcinoma is justified, and serum tumor markers are useful to detect metastases early during the follow‐up, as in our report.

Confocal laser endomicroscopy for the detection of mucosal changes in ileal pouch after restorative proctocolectomy.

BACKGROUND Pouchitis and dysplasia may affect the reservoir after restorative proctocolectomy. AIMS To assess the suitability of confocal laser endomicroscopy for the in vivo diagnosis of mucosal changes in ileal pouch for ulcerative colitis and familial adenomatous polyposis. METHODS Standard endoscopy and endomicroscopy were performed in 18 pouches. Confocal images were scored for the presence of villous atrophy, inflammation, ulceration, colonic metaplasia and dysplasia. Targeted biopsies were taken. Endomicroscopic and histological findings were compared. RESULTS At standard endoscopy, the signs of pouchitis were recorded in 7/18 (38.9%) patients. At endomicroscopy, pathological features were found in 16/18 (88.9%), villous atrophy in 15/18 (83.3%), inflammation in 13/18 (72.2%), ulceration in 3/18 (16.7%), and colonic metaplasia in 12/18 (67.7%). No dysplasia was observed. At histology, abnormalities were present in 17/18 (94.4%): villous atrophy in 15/18 (83.3%), inflammation in 17/18 (94.4%), ulceration in 6/18 (33.3%), colonic metaplasia in 15/18 (83.3%). Morphological changes of the ileal pouch could be predicted with an accuracy of 94.4% (95% CI: 74.2-99.0). The k-value for intra- and interobserver agreement was 0.93 and 0.78, respectively. CONCLUSIONS Endomicroscopy may be helpful in the evaluation of morphologic changes in ileal pouch. The small size of the population sample requires further studies for the results to be confirmed.

Carriage of CARD15 variants and smoking as risk factors for resective surgery in patients with Crohn's ileal disease

Background:  It is controversial whether CARD15 variants are truly associated with a more severe form of Crohns disease. The relative role of CARD15 genotype and smoking in Crohns disease progression is also debated.

Surgery and diagnostic imaging in abdominal Crohn’s disease

Surgery is well-established option for the treatment of Crohn’s disease that is refractory to medical therapy and for complications of the disease, including strictures, fistulas, abscesses, bleeding that cannot be controlled endoscopically, and neoplastic degeneration. For a condition like Crohn’s disease, where medical management is the rule, other indications for surgery are considered controversial, because the therapeutic effects of surgery are limited to the resolution of complications and the rate of recurrence is high, especially at sites of the surgical anastomosis. In the authors’ opinion, however, surgery should not be considered a last-resort treatment: in a variety of situations, it should be regarded as an appropriate solution for managing this disease. Based on a review of the literature and their own experience, the authors examine some of the possibilities for surgical interventions in Crohn’s disease and the roles played in these cases by diagnostic imaging modalities.RiassuntoLa chirurgia è un’opzione terapeutica consolidata per il trattamento della malattia di Crohn refrattaria alla terapia medica e per le complicanze legate a tale patologia quali stenosi, fistole, ascessi, sanguinamento non trattabile endoscopicamente, oltre che per i casi di degenerazione neoplastica. Per condizioni come la malattia di Crohn nelle quali il trattamento medico ha un ruolo primario, altre indicazioni per la chirurgia sono controverse, poiché i suoi effetti terapeutici sono limitati alla risoluzione delle complicanze, e la frequenza di recidive è alta, soprattutto a livello dell’anastomosi. Secondo l’opinione degli autori, tuttavia, la chirurgia non deve essere considerata come ultima opzione di trattamento: in diverse situazioni dovrebbe essere ritenuta come una soluzione adeguata nel trattamento multidisciplinare della patologia. Basandosi sulla revisione della letteratura corrente e sulla propria esperienza, gli autori hanno esaminato alcune possibilità di intervento chirurgico nella malattia di Crohn ed il ruolo che svolgono in queste condizioni le tecniche di imaging.
