Electrophysiological markers predicting impeding AV-block during ablation of atrioventricular nodal reentry tachycardia.

Background: Radiofrequency (RF) ablation of the slow pathway (SP) in atrioventricular nodal reentry tachycardia (AVNRT) is occasionally complicated with atrioventricular block (AVB) often predicted by junctional beats (JB) with loss of ventriculo-atrial (VA) conduction.

Methods: We analyzed retrospectively 153 patients undergoing ablation of SP for typical AVNRT. Patients were divided into two age groups: 127 ≤ 70 years and 26 > 70 years.

Intraperitoneally administered irinotecan with 5-fluorouracil impair wound healing of colonic anastomoses in a rat model: an experimental study.

Aim: The aim of this experimental study is the assessment of the effects of the immediate post-operative intraperitoneal administration of 5-fluorouracil and irinotecan on the healing process of large bowel anastomoses in rats.

Materials And Methods: Sixty male Wistar rats were divided into 4 groups of 15 rats each. The rats underwent large bowel resection and anastomosis, followed by the intraperitoneal administration of normal saline (group 1), 5-fluorouracil (group 2), irinotecan (group 3) or the combination of 5-fluorouracil and irinotecan (group 4).

Idiopathic hypertrophic pyloric stenosis combined with left paraduodenal hernia in an adult.

Objective: We report a case of primary hypertrophic pyloric stenosis combined with a paraduodenal hernia in a 35-year-old woman.

Clinical Presentation And Intervention: The patient presented with signs of obstructive ileus. CT of the abdomen revealed a marked dilatation of the stomach and the proximal jejunum as well as a circumferential thickening of the antral-pyloric region with characteristics indicating hypertrophic pyloric stenosis.

A variant of the double gallbladder. A possible cause of cholelithiasis?

Congenital duplication of the gallbladder is a rare anatomical malformation, which is usually discovered as an incidental finding during cholecystectomy. We report a case of a double gallbladder in a 45-year-old woman, which was discovered during laparoscopic cholecystectomy for symptomatic cholelithiasis. As it was not possible to identify the anatomical structures safely, the procedure was converted to open cholecystectomy.

Lipid peroxidation and inguinal hernia repair. Tension-free vs. Andrews technique.

Aim Of The Study: To evaluate the early effect of inguinal hernia repair by the tension-free method compared to the conventional Andrew's technique on lipid peroxidation.

Patients-methods: Thirty-four patients subjected to elective hernia repair were enrolled in the study divided in two groups. Group A (n=18) underwent hernia repair by the tension-free method using a polypropylene mesh.
