[Gargantua and digestive bariatric surgery].

Morbid obesity significantly reduces life span and is associated with much co-morbid pathology. Diet, behavioral therapy and drugs therapy are largely unsuccessful, however the surgical treatment offers the best hope. This historic review about the bariatric surgery summarizes the jejuno ileal by-pass and the gastric surgery as the gastric bypass and the horizontal or vertical gastroplasties. Procedures that reduce gastric capacity and dietary in take are now considered preferable to those that alter food absorption as they are associated with fewer side-effects. The vertical banded gastroplasty is probably, the best operation for modern Gargantua's men.

[Cesar Roux and his Roux-en-Y anastomosis].

During the last 100 years, since Cesar Roux (1857-1934) began utilizing his "Loop-en-Y" procedure for gastric outlet obstruction, this technique fell into disfavour but later, with the vagotomy, it was adapted for multiple applications. The greatest factor in its revival has been the treatment of postgastrectomy sequels, including alkaline reflux gastritis, reflux esophagitis, dumping and other syndromes. Additionally Roux-en-Y anastomosis has been used to drain diverse organs as the biliary tract, pancreas and esophagus. The main complication of loop-en-Y is the Roux syndrome, secondary to gastric or efferent jejunal stasis, or both. As the centennial of Roux's first use of his eponymic procedure approaches its seems appropriated to remind its memory as a part of our surgical inheritance.

[Results of the surgical treatment of postoperative stenosis of the main bile duct].

Between January 1964 and January 1986, 28 patients with postoperative biliary stenosis were studied and operated. The left hepatic duct were anastomosed with an Y-Roux limb of jejunum in 23 cases; in one case was realized a bi-hepatic jejunostomy and in remaining 4 cases were treated with the Rodney Smith's operation. In the surgical repair of the biliary stenosis the best techniques is the hepato-jejunostomy anastomose described for Hepp in 1954. The very high hepatic stricture may present an almost insoluble problem and the "mucosal graft" of Rodney Smith is the optative operation. The results of the present series is good in the 92.8% of the cases.

[Postoperative alkaline reflux gastritis].

Six patients with alkaline reflux gastritis postoperative were treated between 1977 and 1984 by Roux-en-Y diversion. All of the patients had a typical history of mild epigastric burning pain and bilious vomiting. The diagnosis was reached by endoscopic results of the gastric mucosa. The pain, complaints and the macroscopically apparent gastritis subsided completely after surgery but the histological manifestations of gastritis improved though no disappear. In four cases we used the Roux-en-Y procedure; in two, the Henley jejunal loop with the Soupault-Bucaile, technique. All patients were vagotomized for the fear recurrent peptic ulceration if increased the acid secretion. One patient was most complex because after derivation with Roux-en-Y developed severe diarrhea and was necessary to change to loop jejunal Henley and reversed 10 centimeter the jejunal loop at 1 meter from Treitz angle.

[Extrinsic compression of the hepatocholedocus caused by cavernomatosis of the portal vein. Report of a case].

The extrinsic compression of the hepatocholedochus by a cavernomatosis of the portal vein, is an unusual pathology. The present case begun clinically as an obstructive jaundice, assuming that the vascular origin of the compression increased the litiasic biliary disease. The percutaneous transhepatic cholangiography was the diagnostic method that suggested a double illness of the biliary system. The surgery and the pathology certificated the diagnosis. The correct treatment once confirmed the obstructive trial, must be: the extraction of the biliary gallstones and the bile-digestive derivation (preferently the hepatic-jejunum anastomosis in Y of Roux).

[Cystic dilatation of the choledochus].

A case of choledochus cyst in a woman of 25 years old is reported. The total excision of the cyst with primary anastomosis to the duodenum o jejunum is the best operation, if it isn't possible or dangerous the elective technique is the cystojejunostomy in Roux-Y. It is suggested the advantage to resolve in the best form-excision or cystojejunostomy during the first operation for avoid eventual complications during the late intervention.

[Pseudocysts of the pancreas. Considerations on 18 cases].

The authors present their experience in the study and treatment of 18 patients with pancreatic pseudocysts. Fifteen patients were operated on as follows: 6 external drainage 4 cyst-gastrostomy, 4 cystoyeyunostomy and one had distal pancreatectomy. Nine of the patients who were operated did well and 6 died in the postoperative course; one died after a prolonged period of time.

[Hydrodynamic and radiologic examination of the common bile duct].

The operative study of the common bile duct was carried out with the hydrodynamics methods (flow and resting pressure) in 433 patients and with the operative cholangiography in 383 patients. The hydrodynamics explorations pointed-out a margin of mistake due to falses positives and negatives of the 2.7% and the operative cholangiographies of the 8.6%. The association of both methods, hydrodynamics and radiologycs, allowed us to estimate that the diagnostic mistake is reduced to 0%. It is established in this work the necessity of carring out the flow, the measure of the resting pressure and the cholangiographies; in all the patients that are operated on the biliary tract because the diagnostic accuracy is the 100%. It is discussed the value of the diameter of the common bile duct for affirming the eventual existence of obstruction of the lower part of the common bile duct and the values are correlated, measured in mm., with pathological founds. It is considered the value of the hydrodynamics methods in the diagnostic of the stenosis of the sphincter of Oddi.
