A randomized controlled trial of mesentericocaval shunt with autologous jugular vein.

After a large uncontrolled experience, in April 1976, a randomized clinical trial between side-to-side portacaval anastomosis and a mesentericocaval shunt with internal jugular vein interposition was initiated. Up to April 1979, 23 patients were operated upon with a mesentericocaval shunt and 26 with a portacaval anastomosis. With a mean follow-up time of 23 months, no statistically significant differences in terms of operative mortality, hepatic encephalopathy and long term survival were found between the two operations. Therefore, a mesentericocaval shunt does not appear to offer effective advantages compared with the portacaval anastomosis, and it should be performed in particular instances in which, for anatomic reasons, a portacaval anastomosis cannot be performed.

[Bronchopulmonary carcinoma: influence of type of resection on long term survival].

A statistical comparison between survival and type of resection: Lobectomy and pneumonectomy was made out of 108 patients who had undergone curative resection for lung cancer (with a minimum 3 years follow-up). Analysis was first made on the whole series, then the patients were classified according to histological type (W-PL) or staging (TNM) and finally stratified in 2 control levels (stage and histological type). There was a better prognosis for lobectomy than for pneumonectomy, referring to a single subgroup, but not in a statistically significant way. There was a better prognosis for patients who had been operated for lobectomy S(2) 2 LOB with a 36 months survival for 85%. There were better results for squamous cell carcinoma stage I and II S(2) 1 PNE, for those patients who had been operated for pneumonectomy with a median survival of 32 months and over 3 years survival for 41.7%.

Control of gastroesophageal bleeding varices by percutaneous transhepatic portography.

We used the transhepatic approach to the portal system to obliterate bleeding gastroesophageal varices as an alternative to portosystemic shunt performed as an emergency. In eight of 13 patients, we obtained complete arrest of bleeding, while rebleeding was observed in five patients. The shunt was performed upon six patients, and only one patient died. Transhepatic obliteration of varices seems to be the more useful method for the control of untractable hemorrhage and to prepare the patient for an elective operation.

Comparative results of three different techniques for colonic anastomosis in the dog.

Three different techniques of colonic anastomosis were evaluated in the dog. Left hemicolectomy and two layer anastomosis were performed in ten dogs, one layer anastomosis in ten dogs and sleeve anastomosis in ten dogs. In each group, five dogs were sacrificed on the second postoperative day, and the anastomotic specimen was studied by a bursting test. The remaining five dogs were sacrificed seven days after operation, and the specimen was studied by hydroxyproline dosage and by microscopy. The bursting test showed a significant difference between sleeve anastamosis and other techniques. The results of hydroxyproline dosage showed no significant differences between the different anastamotic techniques.

Mesentericocaval shunt with the internal jugular vein.

Seventy-nine mesocaval shunts using the internal jugular vein and 54 side-to-side portocaval shunts have been performed during the past six years. Patients were evaluated from the stand-point of protection from recurrent bleeding, patency of the shunt, encephalopathy, rehabilitation and long term survival. All of the patients underwent follow-up observation. In a selected group of patients, postoperative angiographic control was performed, and serum levels of octopamine were examined. In the mesentericocaval group, patency of the shunt was demonstrated in 82 per cent, the incidence of encephalopathy was 35 per cent and the long term survival rate, as computed by the actuarial method, was 65 per cent. In the portocaval group, the incidence of encephalopathy was 54 per cent and the survival rate, 38 per cent. There was no correlation between octopamine serum levels and encephalopathy. Persistent perfusion of the liver was documented in 95 per cent of the patents controlled by arteriography in the mesentericocaval group with patent shunts. The mesentericocaval shunt seems to be an effective technique in terms of incidence of encephalopathy and survival rate, but a randomized study will be necessary to prove that this technique is more effective than the standard portocaval shunt.

Portal hypertension treated by left gastro-epiploic to left renal vein anastomosis: case report.

A case of portal hypertension is presented in which because of the presence of multiple thromboses of the main portal branches one of the usual portasystemic shunts could not be performed. An anastomosis between an enlarged left gastro-epiploc vein and the left renal vein was successfully carried out. Six months after surgery the patient was well and no further haemorrhage had occured.
