Preoperative assessment of simple and complex anorectal fistulas: Tridimensional endoanal ultrasound? Magnetic resonance? Both?

Purpose: The purpose of the study is to evaluate the diagnostic value of tridimensional endoanal ultrasound (3D-EAUS) and magnetic resonance (MR) in the preoperative assessment of both simple and complex anorectal fistulas.

Methods: All the patients referred for the treatment of anal fistulas were enrolled in this study and underwent, as preoperative assessment, anamnestic evaluation, clinical examination, and unenhanced and H2O2-enhanced 3D-EAUS and MR. The results of imaging evaluation were compared with surgical findings, considered as reference standard.

Sphincter-saving surgery in low rectal cancer.

A correct surgical approach to rectal cancer today has to make due allowance for both improved overall survival with local control of disease and preservation of the sphincter and urinary and genital functions. Increased understanding of the natural history, the importance of preoperative accurate staging and new surgical techniques may influence future treatment strategies. The aim of this study was to review and make a reappraisal of the role of sphincter-preserving surgery in the treatment of carcinomas of the lower third of the rectum.

[Small intestinal polyposis in Peutz-Jeghers syndrome: combined treatment with surgery and intra-operative endoscopy].

Polyps occur throughout the gastrointestinal tract in Peutz-Jeghers syndrome, but the most serious problems are encountered in the management of small bowel polyposis. We report here on a case of Peutz-Jeghers syndrome admitted to hospital for intestinal obstruction and anaemia. The patient was submitted to colonoscopy, oesophagogastro-duodenoscopy and small bowel enema.
