MTHFR C677T polymorphism and anatomopathological characteristics with prognostic significance in sporadic colorectal cancer.

Methylenetetrahydrofolate reductase (MTHFR) plays a key role in folate metabolism, and folate is implicated in carcinogenesis due to its role in DNA methylation, repair and synthesis. The MTHFR C677T polymorphism is associated with decreased risk of CRC and increased sensitivity to 5-FU treatment. The present study addressed the relationship between this polymorphism and histopathological and immunohistochemical characteristics of prognostic significance in 50 patients from the Canary Islands.

Clinicopathological analysis of factors related to colorectal tumor perforation: influence of angiogenesis.

Colorectal tumor perforation is a life-threatening complication of this disease. However, little is known about the anatomopathological factors or pathophysiologic mechanisms involved. Pathological and immunohistochemical analysis of factors related with tumoral neo-angiogenesis, which could influence tumor perforation are assessed in this study.

Cooperative Study of the Spanish Pancreas Transplant Group (GETP): Surgical Complications.

Unlabelled: Technical failure in pancreas transplant has been the main cause of the loss of grafts. In the last few years, the number of complications has reduced, and therefore the proportion of this problem.

Objectives: The Spanish Pancreas Transplant Group wanted to analyze the current situation with regard to surgical complications and their severity.

[Gallstone ileus as a cause of acute abdomen. Importance of early diagnosis for surgical treatment].

Gallstone ileus is an uncommon type of mechanical intestinal obstruction caused by an intraluminal gallstone, and preoperative diagnosis is difficult in the Emergency department. This study is a retrospective analysis of the clinical presentation of 5 patients with gallstone ileus treated between 2000-2010. Clinical features, diagnostic testing, and surgical treatment were analyzed.

Metastatic lymphs nodes and lymph node ratio as predictive factors of survival in perforated and non-perforated T4 colorectal tumors.

Aims: Recently it has been hypothesized that perforation of colorectal cancer (CRC) itself is not a predictor of poor prognosis. The aim of this study was to analyze the prognostic impact, of the spontaneous perforation of the tumour, metastatic lymph nodes and lymph node ratio (LNR) after potentially curative surgery.

Methods: Retrospective analysis of oncologic outcomes of patients with T4a CRC grouped by perforated and non-perforated tumours.

Abdominal wall hematoma after laparoscopic surgery: early treatment with selective arterial transcatheter embolization.

Bleeding from the site of a trocar insertion is a relatively frequent complication after laparoscopic surgery, despite precautionary techniques aimed at reducing such events. It may result in a hemoperitoneum, requiring emergency reintervention or large hematomas of the abdominal wall. In the latter case, although conservative treatment is possible, hospital stay is prolonged and large amounts of blood-bank resources are consumed.
