[Surgical therapy of severe obesity].

Severely obese patients are vitally endangered by their overweight. Non operative therapies achieve less than 10% of persistent weight reductions in this high-risk group of patients. On condition of correct indications and adequate preoperative information gastric bypass, vertical banded gastroplasty or implantation of the adjustable gastric band represent effective surgical procedures enabling persistent reductions of at least 50% of overweight in 85% of patients.

[Immunoscintigraphy for detection of inflammatory perioperative foci].

The aim of our study was to evaluate the clinical usefulness of a monoclonal antibody (MAB; BW 250/183; Behringwerke, Germany) in patients with suspected perioperative septic foci. The MAB is directed against the nonspecific crossreacting antigen (NCA 95) which has been found on the surface of human neutrophil granulocytes and which represents a murine immunoglobulin isotype of IgG1. Immunoscintigraphy was performed by labelling the MAB with 740 MBq (20mCi) Tc-99m.

Nd:YAG laser treatment of colorectal malignancies: an experience of 4 1/2 years.

Between 1985 and 1990, 517 patients were treated for colorectal malignancies at our department of surgery. Nd:YAG laser therapy was used in 37 cases (7.1%).

Hepatic artery infusion chemotherapy.

Hepatic artery chemotherapy was given to 36 patients, using totally implantable devices consisting of a port and external pump. Twenty-seven patients had inoperable liver metastases of colorectal origin. The infusion system was inserted by laparotomy into the hepatic artery via the gastroduodenal artery.
