The claim that trypsin is inactive within the intrapancreatic channels for many years has been recorded in the classical treatises of physiology ago. However, contrary to some experimenters have indisputably classic dogma extracted pancreatic trypsin active channels. This extremely interesting, not only for its absolute value but especially by their projections to the pathophysiology of pancreatitis should be controlled in multiple and rigorous experiments. We have personally made a short experimental study in the dog. Are the results of this experiment we committed in this preliminary work.

This article describes the operations that can be discussed in the surgical treatment of essential or idiopathic megaesophagus exposed. Nerve sections, only splanchnic section is practiced by some with a curative purpose. The anastomosis Gröndahl how the cardioplástías Marwedel's way-Wendell, constantly give perfect or good immediate results. Two of our cases (Case No. 1, 2) we present, are typical examples. The future of surgery with these techniques cardioplasty anastomosis or darkens the output almost constant reflux of gastric juice into the stomach. The consequences of this are dire reflux. The resulting almost obligatory: peptic esophagitis, is a new or more severe as the disease megaesophagus. The vast majority of surgeons, with few exceptions, has abandoned these interventions has been seen when the remote results.

The purpose of this short paper is to present our statistical surgery of the large intestine and add some comments.

Stomach resection is currently the only logical solution in the treatment of adenocarcinoma of the stomach. The extension of this visceral resection is logged in to the extent of cancer visceral. In some cases it is necessary to extend the esophagus; Total gastrectomy. In other cases it is necessary to remove organs or segments órghanos invalid; Extended gastrectomy.

Not only the interest - very desirable in the surgeon - to maneuver in unfamiliar fields and anatomical long inspired him fearful and cautious respect, which has prompted some to take the scalpel nerve abdomen neurovascular crossroads in which was a simple approach and boldness.
