Abstract

We developed a new micro-iris retractor to achieve temporary intraoperative pupillary mydriasis in selected eyes undergoing pars plana vitreous surgery. The micro-iris retractor and its use were compared with previous methods for obtaining adequate intraoperative pupillary dilation.

[Esophageal dilatation using the Savary-Gilliard sound set].

Authors present a method of esophageal dilatation and report their experiences. The place of esophageal dilatation among other therapeutic approaches of esophageal stricture is discussed. The advantage of Savary-Gilliard bougies and guide wire and its applications are presented. During one and a half year 218 esophageal dilatations were performed at 82 patients. 11 patients were intubated endoscopically. Esophageal perforation occurred in 2 cases (0.93%). Dilatation of the esophagus with Savary-Gilliard bougies and using of the guide wire are considered a safe and many-sided method in the diagnosis and treatment of esophageal strictures.

The use of endotracheal tubes to assist in manipulation of esophageal strictures, in elongation of the esophagus in esophageal atresia, and in gastrojejunal feeding tube placement.

Because of the special qualities of a PVC endotracheal tube (smooth, soft, pliable but still with a patent lumen), it serves very well for the intubation of the esophagus or the duodenum through an established gastrostomy. In this article the use of endotracheal tubes in different manipulations of the esophagus and gastroduodenum is described.

The influence of harvesting technique on endothelial preservation in saphenous veins.

To study optimal conditions of preparation of saphenous veins as coronary artery bypass grafts, segments of saphenous veins were obtained from 29 consecutive patients undergoing coronary artery bypass grafting. The saphenous vein segments were divided into three groups. In Group I, 10 saphenous vein segments were harvested using a "no-touch" technique without any other preparation aids. In Group II, 10 saphenous vein segments were removed while distended at 70-120 mm Hg with a balanced pH electrolyte solution at 37 degrees C. In Group III, consisting of 10 saphenous vein segments, nitroglycerin (1 microgram/ml) was added to the distending solution used in Group II. Samples of saphenous vein were assessed in a blind study using light and scanning electron microscopy to estimate endothelial cell preservation by the three harvest techniques. Saphenous veins receiving only a no-touch dissection technique without distention solution (Group I) revealed significantly better endothelial preservation (P less than 0.005). The administration of distention solution alone, or with nitroglycerin, to saphenous veins in situ using our operative technique during harvest does not appear to protect endothelial-integrity and may be harmful.
