Comparative study between total and subtotal gastrectomy for distal gastric cancer: Meta-analysis of prospective and retrospective studies.

There is no clear agreement on the type of gastrectomy to be used (either total [TG] or distal [DG]) in middle or distal gastric cancer, especially when it is undifferentiated or Lauren diffuse type. In this meta-analysis, we intend to define which of the 2techniques should be recommended, based on survival, morbidity and mortality rates. Prospective and retrospective studies comparing both techniques have been included for a total of 6303 patients (3,641 DG and 2,662 TG).

[Liver metastases from colorectal cancer. Is the practice of surgery based on the best clinical evidence possible?].

To date, surgical resection remains the only curative treatment for liver metastases from colorectal cancer. However, the evidence supporting this treatment is based on retrospective studies. The lack of level I clinical evidence has stimulated strong interest in identifying the factors predictive of recurrence, and even to use them to create clinical risk scores (assigning one point to each factor for poor prognosis), in which a higher score indicates a poorer prognosis.

Hartmann's procedure for obstructive carcinoma of the left colon and rectum: a comparative study with one-stage surgery.

Introduction And Objectives: Despite the criticisms from prestigious expert committees, a high percentage of surgeons continue to use, as the technique-of-choice, Hartmann's procedure for acute malignant intestinal obstruction of the distal colon and rectum, without faecal peritonitis. We have reviewed our results with this technique and compared them with other series of patients in the literature undergoing one-stage surgery (resection with primary anastomosis or sub-total colectomy).

Material And Methods: A retrospective and descriptive study using clinical histories and, from which, the variables studied were: median hospitalisation stay, morbido-mortality and reconstruction index.
