[Ranitidine in the treatment of duodenal ulcer. Initial clinical experience with 33 patients].

The short and medium term results obtained with ranitidine on 33 duodenal ulcer patients are reported. The results obtained indicate that ranitidine is excellent for initial therapy but there are doubts about its efficacity in the prophylaxis of recurring ulceration during maintenance treatment. In addition, about 9% of the patients suffered side effects to the extent that treatment had to be interrupted.

[A new technic of venous thrombectomy of the lower limbs].

A personal venous thrombectomy technique employing a modified Fogarty catheter is described. The end of the catheter to which the syringe is normally applied is cut off to enable it to be used in a retrograde manner. In this way, thrombectomy is always performed in the direction of the current, irresapective of the site of the thrombosis in the venous axis of the lower limbs. This type of operation offers two advantages. It preserves the integrity of the valves and does away with the risk of intraoperative embolisms. It is described as "physiological thrombectomy". If the thrombosis involves the entire iliac-femoro-popliteal axis, the catheter is inserted retrogradely via the small saphenous at the, and removed via an iliac phlebotomy obtained by means of an extraperitoneal abdominal incision. When the thrombosis is femoropopliteal only, the catheter is inserted through the origin of the small sphenous and withdrawn via the venous incision. Lastly, in cases where the common iliacofemoral axis alone is involved, retrograde insertion takes place through the large saphenous vein in the inguinal region. Preliminary results obtained with the technique are described.

[Primary adenocarcinoma of the 3d duodenal segment].

A case of primary duodenal adenocarcinoma is described. A discussion is made about the rarity of this tumor that, as it is frequency misdiagnosed in cases of malignant neoplasms of the papilla of Vater and of terminal part of the common biliary duct, may be greater than all previously thought. Tumors of the third part of duodenum are even more uncommon. Whipple resection seem the best cure of this tumors, as results from long term survival.

[Study of the relations between recurrent nerve and inferior thyroid artery (author's transl)].

The importance of a knowledge of the relations between recurrent nerve and inferior thyroid artery, in order to minimise the incidence of injuries to the nerve during thyroidectomy, is stressed. These relations are analysed from the anatomo-surgical standpoint, with particular emphasis on the great variability to which they are subject. It is concluded by asserting the utility of prior location of the recurrent nerve, with an indication of some basic concepts that must always be borne in mind when performing thyroid surgery.

[Proposed technic of drainage tunneling in marsupialization of hydatid cysts of the hepatic cupula].

Even though the present tendency is to make use of radical operations, such as pericystectomy, hepatic resection and lobectomy, in the surgical management of hydatidosis of the liver, marsupialisation is still the method of choince in a large and clearly defined number of cases. While usually simple, this operation may prove difficult and complex when used on cysts of the cupola, since it may often be necessary to mobilise the liver to a large extent and employ damaging approach routes. A description is offered of a particular technique for tunnelling the desinage tube which considerably simplifies marsupialisation in cases of this kind.

[Our experience in the treatment of superior vena cava syndrome].

In clinical practice SVC syndrome is an important problem, given both the nature of the disease and its fast lethal evolution. Therapy must be instituted as soon as possible because the chances of a positive result are directly related to the staging of the primary illness. Surgery, chemotherapy and high energy therapy can be used. From the literature, although controversial, the superiority of surgical therapy is clear; particularly if up-to-date vascular reconstruction techniques are employed. From March 1980 to March 1988 8 cases of SVC syndrome were observed in which the aetiology was as follows: Hodgkin's disease (2 cases); secondary catheter thrombosis (1 cases); lung carcinoma (5 cases). The 2 cases of Hodgkin's disease were treated by chemotherapy; the secondary thrombosis by open thrombectomy. In the other 5 cases an innominate vein right appendage by-pass was used (3 PTFE, 2 pericardial grafts). The results were encouraging: complete, long-term remission was observed in the Hodgkin and thrombectomy patients. A PTFE graft thrombosis occurred in 2 cases but in the other cases the by-pass is functioning well at a mean 13 months follow-up.
