[Local recurrence of rectal carcinoma].

The authors discuss a group of 88 dispensarized patients from a group of 153 operated during 1988-1992 on account of a malignant rectal tumour. Local regional relapses were found in 14 patients (15.9%).

[Endorectal sonography and computer tomography in the treatment of rectal malignancies].

The authors evaluate the contribution of computed tomography and endorectal sonography for the diagnosis and treatment in 32 patients from a total number of 84 patients treated on account of a rectal malignoma at the First Surgical Clinic of the Medical Faculty and Faculty Hospital in Olomouc during the three-year period between 1990 and 1992. The results of the examination were compared with the finding on operation and the histological examination. The authors maintain that both methods are useful but in different ways.

[Treatment of glioblastoma multiforme].

The authors evaluate therapeutic results in 31 patients with the diagnosis of multiform glioblastoma. The comprehensive therapeutic procedure used as a rule which involves surgery, radiotherapy and in some instances also chemotherapy still gives very unsatisfactory results. The mean survival period of patients after surgery was 26.

[Volvulus of the cecum].

The authors present a group of seven patients treated at the First Surgical Clinic of the Faculty Hospital Olomouc on account of volvulus of the caecum during the period between 1963 and 1992. Based on their own experience which is consistent with results reported in the literature, the authors discuss the problem of diagnosis and optimal treatment of volvulus of the caecum.
