The majority of patients affected by Crohn’s disease(CD)develop a chronic condition with persistent inflammation and relapses that may cause progressive and irreversible damage to the bowel,resulting in stricturing or penetrating complications in around 50%of patients during the natural history of the disease.Surgery is frequently needed to treat complicated disease when pharmacological therapy failes,with a high risk of repeated operations in time.Intestinal ultrasound(IUS),a non-invasive,cost-effective,radiation free and reproducible method for the diagnosis and follow-up of CD,in expert hands,allow a precise assessment of all the disease manifestations:Bowel characteristics,retrodilation,wrapping fat,fistulas and abscesses.Moreover,IUS is able to assess bowel wall thickness,bowel wall stratification(echo-pattern),vascularization and elasticity,as well as mesenteric hypertrophy,lymph-nodes and mesenteric blood flow.Its role in the disease evaluation and behaviour description is well assessed in literature,but less is known about the potential space of IUS as predictor of prognostic factors suggesting response to a medical treatment or postoperative recurrence.The availability of a low cost exam as IUS,able to recognize which patients are more likely to respond to a specific therapy and which patients are at high risk of surgery or complications,could be a very useful instrument in the hands of IBD physician.The aim of this review is to present current evidence about the prognostic role that IUS can show in predicting response to treatment,disease progression,risk of surgery and risk of post-surgical recurrence in CD. 展开更多

AIM: To evaluate the effect of resistance to activated protein C (aPCR), the most common known inherited thrombophilic disorder, on the risk of intestinal operation of fi brostenosis in patients with Crohn’s disease (CD). METHODS: In a previous study, we assessed the prevalence of aPCR in CD. In a retrospective case- controlled study, 8 of these CD patients with aPCR were now compared with 24 CD patients without aPCR, matched by gender, age at diagnosis and duration of disease in a 1:3 fashion. The primary end point was the occurrence of an intestinal CD-related operation with evidence of fibrostenosis in the bowel resection specimen. RESULTS: The Kaplan-Meier analysis revealed that patients with aPCR had a lower probability of remaining free of operation with f ibrostenosis than patients without aPCR (P = 0.0372; exact log-rank test) resulting in a signifi cantly shorter median time interval from diagnosis of CD to the fi rst operation with fi brostenosis (32 vs 160 mo). At 10 years, the likelihood of remaining free of operation with fi brostenosis was 25% for patients with aPCR and 57.8% for patients without aPCR. CONCLUSION: CD patients with aPCR are at higher risk to undergo intestinal operation of fi brostenosis than those without aPCR. This supports our hypothesis of aPCR being a possible risk factor for fi brostenosis in CD. 展开更多

Colorectal cancer (CRC) is the 3<sup>rd</sup> most common cancer in the United States with more than 10000 new cases diagnosed annually. Approximately 20% of patients with CRC will have distant metastasis at time of diagnosis, making them poor candidates for primary surgical resection. Similarly, 8%-25% of patients with CRC will present with bowel obstruction and will require palliative therapy. Emergent surgical decompression has a high mortality and morbidity, and often leads to a colostomy which impairs the patient&#x02019;s quality of life. In the last decade, there has been an increasing use of colonic stents for palliative therapy to relieve malignant colonic obstruction. Colonic stents have been shown to be effective and safe to treat obstruction from CRC, and are now the therapy of choice in this scenario. In the setting of an acute bowel obstruction in patients with potentially resectable colon cancer, stents may be used to delay surgery and thus allow for decompression, adequate bowel preparation, and optimization of the patient&#x02019;s condition for curative surgical intervention. An overall complication rate (major and minor) of up to 25% has been associated with the procedure. Long term failure of stents may result from stent migration and tumor ingrowth. In the majority of cases, repeat stenting or surgical intervention can successfully overcome these adverse effects. 展开更多

Abdominal cocoon,the idiopathic form of sclerosing encapsulating peritonitis,is a rare condition of unknown etiology that results in an intestinal obstruction due to total or partial encapsulation of the small bowel by a f ibrocollagenous membrane.Preoperative diagnosis requires a high index of clinical suspicion.The early clinical features are nonspecif ic,are often not recognized and it is diff icult to make a def inite pre-operative diagnosis.Clinical suspicion may be generated by the recurrent episodes of small intestinal obstruction combined with relevant imaging f indings and lack of other plausible etiologies.The radiological diagnosis of abdominal cocoon may now be conf idently made on computed tomography scan.Surgery is important in the management of this disease.Careful dissection and excision of the thick sac with the release of the small intestine leads to complete recovery in the vast majority of cases. 展开更多
