[Influence of tumor size and intestinal wall invasion on development of colorectal liver metastases].

While the general prognostic factors for colorectal carcinoma have been widely researched, the compound relationships between tumor characteristics and development of colorectal liver metastases have not been clearly understood. The aim of this study was to determine which histopathological characteristics of colorectal cancer may be associated with subsequent development of colorectal liver metastases. We performed retrospective and prospective study which included 80 patients operated for colorectal carcinoma on the First Surgical Clinic of Clinical Center of Serbia in Belgrade.

Endorectal ultrasound (ERUS) in pelvic disorders.

Endorectal ultrasound (ERUS) imaging is a complex process using electronic devices to control ultrasound waves and produce images of anatomic structures. It is a simple, cheep and well-tolerated procedure that provides excellent images of rectal and anal canal wall and pelvic floor muscles together with surrounding organs and tissues. The direct imaging of anal canal and pelvic floor muscles with surrounding tissues allows one to identify sphincter defects, anorectal abscesses and fistulas as well as great variety of benign and malignant pathology of the pelvis.

Discriminant analysis of pre- and intraoperatively detected prognostic factors influencing lymph node involvement in patients with colorectal carcinoma.

Background/aims: The aim of this study was to establish whether, and to what extent, pre- and intraoperatively detected characteristics (demographic, anamnestic and laboratory data) and tumor characteristics can be used in the assessment of regional lymph node involvement in patients with colorectal carcinoma. The assessment also included the number of lymph nodes involved in patients with positive lymph nodes. Considering that the number of obtained lymph nodes widely varies in resected specimens, assessment parameters also included the percentage of the involved lymph nodes within the total population of lymph nodes.

Correlation of macroscopic and histological characteristics in the regional lymph nodes of patients with rectal and sigmoidal adenocarcinoma.

Background/aims: The number of involved lymph nodes is a relevant prognostic parameter which determines the duration of survival in patients with colonic and rectal adenocarcinoma. The purpose of this study was to establish a correlation between the macroscopic (size and consistency) and microscopic characteristics of the regional lymph nodes (type of involvement in tumor tissue, state of the capsule, adherence of the lymph nodes, etc.) in patients with colorectal carcinoma.

Isolated hydatid cyst of the adrenal gland.

Hydatide disease of the adrenal gland is extremely rare, even in disseminated disease. Isolated cyst of the gland is even more rare. Only 9 of such cases seem to have been described so far.
