[Diagnosis and treatment of rectal melanoma].

Rectal melanoma is encountered rarely, is extremely malignant and prone to quick dissemination. The site of the tumor significantly complicates the diagnosis making inexperienced physicians to suspect polyps or hemorrhoids. It is only tumor destruction and ulceration that ascertain cancer. Misdiagnosis of rectal melanoma is responsible for rapid dissemination of malignant cells following undue biopsy. In suspected melanoma it is valid to perform wide electroexcision of the tumor with rapid histological examination. The survival is dependent on melanoma stage, ulceration and destruction, involvement of lymph nodes, histological appearance.

[Obturation ileus in cancer of the large intestine].

The analysis of treatment and diagnosis is presented for 168 colon cancer patients with occlusive ileus. Late diagnosis is responsible for high percentage of palliative operations (61.9%) with a 26% mortality. Radical surgery involves, as a rule, delayed primary one-stage resection and establishment of a single- or doubled-barreled anus. The mortality in this case reaches 19%. Advances in colon cancer treatment results and ways to reduce mortality in this conditions lie in early diagnosis and better knowledge by general practitioners of occlusive ileus pathogenesis and clinical appearance.

[Disorders of microcirculation in patients with acute surgical diseases of the biliary tract].

The authors provide the results of studying the microcirculation in 85 patients with acute cholecystitis and 56 patients with mechanical jaundice caused by choledocholithiasis. The data were obtained with the aid of bulbar capillaroscopy during conservative and surgical treatment. Considerable alterations were detected in all the components of the microcirculation (perivascular, vascular, intravascular), correlating with the gravity of destructive lesions in the gallbladder, duration and degree of jaundice. The times and degree of the normalization of microcirculatory disorders were defined.
