Accuracy of magnetic resonance enterography in the preoperative assessment of patients with Crohn's disease of the small bowel.

AIM: To assess the accuracy of magnetic resonance enterography in predicting the extension, location and characteristics of the small bowel segments affected by Crohn's disease. METHOD: This is a prospective study including a consecutive series of 38 patients with Crohn's disease of the small bowel who underwent surgery at a specialized colorectal unit of a tertiary hospital. Preoperative magnetic resonance enterography was performed in all patients, following a homogeneous protocol, within the 3 months prior to surgery. A thorough exploration of the small bowel was performed during the surgical procedure; calibration spheres were used according to the discretion of the surgeon. The accuracy of magnetic resonance enterography in detecting areas affected by Crohn's disease in the small bowel was assessed. The findings of magnetic resonance enterography were compared with surgical and pathological findings. RESULTS: Thirty-eight patients with 81 lesions were included in the study. During surgery, 12 lesions (14.8%) that were not described on magnetic resonance enterography were found. Seven of these were detected exclusively by the use of calibration spheres, passing unnoticed at surgical exploration. Magnetic resonance enterography had 90% accuracy in detecting the location of the stenosis (75.0% sensitivity, 95.7% specificity). Magnetic resonance enterography did not precisely diagnose the presence of an inflammatory phlegmon (accuracy 46.2%), but it was more accurate in detecting abscesses or fistulas (accuracy 89.9% and 98.6%, respectively). CONCLUSION: Magnetic resonance enterography is a useful tool in the preoperative assessment of patients with Crohn's disease. However, a thorough intra-operative exploration of the entire small bowel is still necessary.

Use of a linear stapler for the treatment of ileocolic fistula in Crohn's disease.

AIM: The study reports an easy technique for surgical management of some forms of ileocolic fistula in Crohn's disease. METHOD: Five patients with Crohn's disease with ileocolic fistula (2011-2014) have been managed by the application of linear stapler devices. RESULTS: Postoperative course was satisfactory in all patients. At 1 year there was no evidence of stricture or fistula formation and no patient had required reoperation. CONCLUSION: The technique is easy and effective and can be used in open and laparoscopic surgery.

Complicaciones de la cirugía tiroidea / Complications of thyroid surgery

En este trabajo se estudian las complicaciones de la cirugía tiroidea, aportando tanto la experiencia personal de nuestro servicio como la de la bibliografía general. Estudiando todas estas complicaciones se observa que la experiencia del cirujano y una técnica cuidadosa son los factores más determinantes de la morbilidad de esta cirugía. La iatrogenia recurrencial, hemorrágica y la hipocalcemia aumentan con la cirugía oncológica y de repetición. Se insiste en la necesidad de la disección de los nervios recurrentes hasta su entrada en la laringe, y en la búsqueda sistemática de las cuatro paratiroides. Existe una relación directa entre el número de paratiroides encontradas y el grado de hipocalcemia. La necesidad de drenajes es controvertida, pero éstos son preferibles ante la agresividad de la cirugía tiroidea actual (AU)

[Perforation of hollow viscera in abdominal injuries]. / Perforación de víscera hueca en traumatismos abdominales.

OBJECTIVE: This is a retrospective study to evaluate our results in the treatment of abdominal trauma. DESIGN: We have analysed the incidence, the clinical characteristics, the diagnosis, the indications for laparotomy, the therapeutic methods and the morbidity-mortality. During the last 14 years we have operated on 29 hollow viscus injuries. They were divided into two groups: Eleven with penetrating or open trauma and 18 with blunt or closed traumatism. RESULTS: In the cases of blunt trauma 36.8% of injuries were located in the proximal jejunum, 21% in the terminal ileum, 15% in the colon. In the cases of penetrating trauma, small intestinal perforation predominated (46.9%). In 23.5% of the cases the colon was affected. Morbidity in blunt trauma was 38.8% and 0% in penetrating trauma. The mortality in the two groups has been zero. CONCLUSIONS: The most common surgical procedure practised for injuries to the small intestine was simple suture, and for injuries to the colon, colostomy. The most usual surgical procedures in penetrating trauma were simple suture in all small intestine injuries and for colonic lesions half had primary closure and half suture plus colostomy.
