In a 30-year-old man with Zollinger-Ellison syndrome, the only detectable gastrinoma was in the right liver lobe. Removal of the lobe, without additional gastric surgery, was followed by normalization of the gastrin level. Long-term follow-up confirmed the good result. The usefulness of quick intraoperative gastrin assay is stressed.
The paper reports the results of a randomised study carried out on a pool of 100 patients undergoing surgery in order to assess the efficacy and tolerability of orally administered heparan sulfate versus heparin calcium in the prevention of postoperative deep-vein thrombosis. Despite the limits of oral administration, heparan sulfate is indicated in the pharmacological prevention of postoperative deep-vein thrombosis.
A series of 47 patients undergoing abdomino-perineal resection of the distal colon and anorectum and construction of a continent perineal colostomy using electrostimulated gracilis muscle is described. External and implanted pulse generators have both been used. An analysis of complications and oncological data are reported. There was no operative mortality. The incidence of complications, divided into three classes, mild (62%), moderate (27%) and severe (11%), has not significantly altered the functional results, with the exception of early ischaemia of the colonic stump in two cases. During the first 22 cases, no preoperative oncological staging was performed. In the last 23 patients endorectal ultrasonography and CT scanning were carried out. Functional results were evaluated by electromanometry, electromyostimulation and dynamic defaecography. Clinical data assessed postoperatively showed good function in 65% of cases, fair in 22.5% and poor in 12.5%. The quality of life in 15 patients with a perineal colostomy and electrostimulated gracilis was significantly better than in 15 patients having an abdomino-perineal resection without gracilis plastic reconstruction.
