Sonographic follow-up after visceral artery stenting.

Objective: The aim of this study was to evaluate the sonographic features of stents and the flow parameters of the visceral arteries after stent implantation.

Methods: Since 1996, 34 stenoses of the visceral arteries (2 mesenteric, 4 celiac trunk, and 28 renal arteries) in 28 patients have been treated with metallic stent implantation in the Department of Radiology of Szeged Medical University. All these patients were regularly followed sonographically.

[Malignant hemangiopericytoma with breast metastasis].

The authors report on a rare case of malignant hemangiopericytoma. A 56-year old female patient had developed a painless node on her left gluteal region 20 years ago. Years later, the resistance became tender and was subsequently surgically removed.

[Total mesorectal excision with ultrasonic coagulation knife ("UltraCision") in surgery of rectal cancer].

The authors report a total of 62 middle and low third rectal cancer cases operated on by total mesorectal excision by the method of Heald. The oncological basis of this procedure is the horizontal regional metastatization of rectal cancer. The total mesorectal excision facilitates, the low anterior resections and preservation of sphincter with an ultra-low colorectal, or coloanal anastomosis using the double stapling technique.

Use of harmonic scalpel for division of short gastric vessels at laparoscopic Nissen fundoplication. A new method.

The essential of laparoscopic Nissen fundoplication is creating a loose and tension free wrap requiring mobilisation of the gastric fundus. Division of the short gastric vessels (SGV) is a standard component of that procedure which requires considerable part of the operation time, and despite of a careful dissection sometimes significant blood loss can be occurred. The Ultracision Harmonic Scalpel (HS) makes the process quicker safer and can cause less intraoperative complication.

Use of harmonic scalpel at laparoscopic cardiomyotomy. A new method.

The laparoscopic cardiomyotomy with anterior fundoplication (Heller-Dor procedure) is accepted for treatment of esophageal achalasia. The crucial point of the procedure is proper myotomy and avoid perforation of the esophagus. Hook cautery is widely accepted to dissect the oesophageal muscle.
