[Immediate prognosis factors in total gastrectomy in cancer]. / Factores pronósticos inmediatos en la gastrectomía total por cáncer.

We present a series of 76 patients operated over a period of nine years, diagnosed as gastric cancer (CG), in whom radical oncologic total gastrectomy (GT) with esophago-jejunal anastomosis (EY) on a Roux-en-Y loop (Y-R) was performed. The tumor was located in the cardias in 27 patients, body in 37, fornix in 3, gastric stump in 7 and over plastic linitis in 2. We performed total gastrectomy enlarged to the spleen in 63 patients, to the pancreas in 28, to the colon in 5 and to the liver in 4. We describe the most salient technical details of the surgical intervention. Twenty-six percent of the patients presented postoperative complications, which we divided into two groups: anastomosis failures, among which are emphasized 4 severe esophagojejunal fistulas, a fistula of the duodenal stump (MD) and respiratory complications. The mortality was 7.8%, corresponding to 4 esophago-jejunal fistulas, 1 fistula of the duodenal stump and 1 bilateral bronchopneumonia. We analyzed various parameters that we consider important prognostic indicators of postoperative morbi-mortality. Applying the Fischer test, we attempted to assign statistical significance to these parameters. Age over 60 years increased postoperative mortality. Super-radical surgery did not increase mortality. On the other hand, patients in stages IIIb and IV have a worse prognosis, with a mortality in the first 30 days of 28.5%. Esophago-jejunal anastomosis on a Roux-en-Y loop is the procedure of choice used by our center after total gastrectomy for gastric cancer, yielding the most acceptable morbi-mortality figures.

[Results of extended resections in colorectal cancer]. / Resultados de las resecciones ampliadas por cáncer colorrectal.

We present 50 cases of super-radical surgery in cancer of the colon and rectum with tumoral spread. In the same period of time a total of 426 colorectal neoplasms were operated on, which represents 11% of the total. The mean age was 65.7 years, with a predominance of females (29/21). In every case the primitive tumor and contiguous organ affected were excised with an oncologic criterion; the principal location was the rectum, with 14 cases, and the viscus most affected was the female genital tract. The mean hospital stay was slightly longer than that of the general series (20.9/14); the mortality was 4%, a figure similar to that of the general series; the index of morbidity did not rise, survival was comparable and the patient's comfort was enhanced. In our opinion, this technique is indicated in all cases in which the tumor invades contiguous regions when local and/or general conditions permit.
