[The place of surgery in the complex treatment of gastric cancer].

The fact that the first symptoms of gastric cancer occur when therapy, even surgical, is limited to palliative objectives, was the starting point of the present study. A clinical study was carried out in a group of 158 patients with gastric cancer admitted to the Surgical Clinic II of Cluj-Napoca in the past 10 years. The most frequent location of the gastric neoplasm was the antrum-pylorus, though there were also extended tumours that invaded the neighbouring organs. Secondary processes were evidenced in over 70% of the patients studied. This fact, together with the associated conditions, made us limit the gastric resection even for the cases in which we considered total extensive gastrectomy to be the best solution. The methods of restoration of the gastric passage were esophago-jejunostomy on the Y loop in the first place, followed by gastro-jejunostomosis with the other techniques of gastric reconstruction. Palliative procedures such as gastro-enteroanastomosis or nutritional gastro-jejunostomy were sometimes necessary. Good postoperative results were obtained in 69% of the patients, which emphasizes once again the importance of this study.

[Clinical, diagnostic and therapeutic problems in the postthrombotic syndrome. Our experience].

An analysis is presented, of the experience acquired in the II-nd Surgical Clinic of Cluj-Napoca in connection with 150 cases of postthrombotic syndrome followed and treated over the last 5 years (1983-1987). Considerations are made concerning terminology, and evaluation of diagnostic and therapeutic means applied. The post-thrombotic syndrome develops in a variable interval after the thrombophlebitis (months and even years). A series of factors prevent of enhance the development of the syndrome (98% diagnostic errors and therapeutic failures). Phlebography is mandatory in cases where surgery is considered. Noninvasive explorations (Doppler, plethysmography) limit the use of phlebography. The most efficient treatment is prophylaxis (consisting in the prophylaxis and the correct treatment of thromboembolic disease). The usual treatment is mainly medical and conservative (59.4%). Surgery is carried out in cases where the superficial, the communicating and the deep venous systems are involved.

[Venous emergencies. Personal experience and viewpoint].

Based on a casuistic report of 226 cases, the authors propose a classification of venous emergencies, including acute deep thrombo-phlebites (with their anatomo-clinical and topographical varieties), the complications of varicose disease, venous traumatism and anorectal venous thrombosis. The authors touch on problems associated with clinical and paraclinical diagnosis, prophylaxis and active surgical therapy, respectively thrombectomy, ligation of the long saphenofemoral junction, the treatment of varico-phlebitis and urgent traumatic lesions, the thrombectomy and radical cure of haemorrhoids. The coupling of any of these affections presents a potential of great seriousness, sometimes a major vital risk which necessitates immediate therapeutic intervention. The classification of the idea of "venous emergency" in comparison with that of "arterial emergency", is outlined, and the authors mention that a surgical treatment in these affections is to be preferred.

Experimental preparation of deantigenized vascular heterografts and study of tolerance after transplantation.

A new technique in preparing a heterograft is presented. Deantigenized calf carotid arteries are obtained by papain digestion and formol tanning. The biochemical determinations show a pronounced reduction in total protein content after papain digestion. The formol tanning gives a good rigidity and elasticity in adapting to different blood volumes without aneurysmal dilatation. Eight dogs were grafted : two died after surgery, two were killed after 35 days and two others 60 days after transplantation, one died after 8 months and one is alive 30 months after transplantation. The good in vivo tolerability has been appreciated. There have been no haemodynamic troubles and no cell changes of rejection. An insignificant quantity of immunoglobulins G has been found in the sera of the animals with heterografts. These data draw attention on the possibility of the use, in clinical practice, of the deantigenized calf arteries.

[The experimental heterotopic transplantation of an isolated segment of colon].

The heterotopic transplantation of isolated colon segment was achieved in the cervical region, for to study the behaviour of the colon in this new situation. The study included 20 dogs from which there were taken segments of 10 cm length from, the left colon. Then was prepared the common carotid artery, superficial jugular vein and their branches. In 5 dogs the cervical esophagus was resected. Then was performed the transplant using micro-surgical techniques. In 15 dogs the colon was exteriorized at the skin and in 5 dogs the colon was placed between the ends of the esophagus. In 76% of cases the postoperative evolution was good. From the viable colon transplants were taken fragments for histologic examinations after 1, 2 respectively 4 weeks postoperative. The results obtained, recommend the colic transplant as a possible graft for repairing the cervical esophagus defects.
