[Changing susceptibility patterns of surgical site infection pathogens after the introduction of modern perioperative chemotherapy in the emergency surgery clinic].

993 surgical site infection aerobic pathogens are isolated over a six-year period (I.1994-I.2000) by the Microbiology Laboratory at University Hospital "Tzaritza Joana".

[Tactics and operative methods in treating complicated colorectal cancer].

Over the period 1993-1998, a total of 385 patients with complicated colorectal cancer are subjected to treatment in the clinic of emergency surgery--University Hospital "Queen Giovanna", Sofia. Obturation is the commonest form of complication--43.8 per cent, perforation within the tumor or diastasis noted in 27 cases (7.

[Large-intestine perforations caused by primary colorectal cancer].

Twenty-seven cases of perforation, produced by primary colorectal carcinoma over the period 1993-1998, are described. The underlying causes of colorectal carcinoma complication and types of perforations observed are discussed. This is a report on personal experience with the therapeutic approach and operative management of this severest complication of colorectal carcinoma.

[The long-term results in complicated colorectal cancer (survival for over 3 and 5 years)].

Colorectal cancer survival depends on: stage of primary neoplastic process development, clinical complication pattern and clinical course of the disease, type (radicalism) of the surgical intervention done and histological verification of blastoma. As shown by the results, postoperative lethality in complicated colorectal carcinoma cases amounts to 17.1 per cent, whereas in those undergoing radical surgery for uncomplicated carcinoma it amounts to 6.
