Total fistulectomy, sphincteroplasty and closure of the residual cavity for trans-sphincteric perianal fistula in the elderly patient.

Background: Perianal fistula is a complex and frequent disease. At present, no treatment nor technique has shown an absolute superiority in terms of efficacy and recurrence rate. The technique has to be chosen considering the balance between faecal continence preservation and disease eradication.

Multiple metastases of soft tissue visualized by technetium-99m-methylene diphosphonate scintigraphy: a case report.

Introduction: Lungs and liver are the most common sites of colorectal cancer metastases after regional lymph nodes, but metastases to unusual sites are reported. Heterotopic bone formation in soft tissues from colorectal cancer is a rare metastatic occurrence.

Case Presentation: We present the case of a 29-year-old Caucasian man affected by colon adenocarcinoma with multiple soft tissue metastases visualized by magnetic resonance imaging, computed tomography scan and scintigraphic bone scan.

Anatomical lymph node mapping in normal mesorectal adipose tissue.

Purpose: In view of divergent outcomes of surgery for rectal cancer despite standard protocols, the aim of this study was to provide a basis for improving lymph node assessment by defining the number, shape, and distribution of all lymphatic structures in the mesorectum.

Methods: Cadavers from 6 males and 6 females who died from causes other than colorectal or neoplastic pathologies were studied. Rectum and mesorectum were excised en bloc.
