[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. On histology, the lesion was identified as malignant hemangiopericytoma. After a symptom-free period of 8 years distant pulmonary metastases arose, which were removed by surgery again. Shortly afterwards the patient manifested with further metastasis involving the lung again, as well as the abdomen, the skin and the breast, leading to the patient's death 2 years later. The authors review the literature, clinical course, diagnostic possibilities, prognosis and therapeutic options of malignant hemangiopericytomas. Special attention is drawn to the unexceptionally long clinical course at this particular malignancy, as well as to the late occurrence of metastases and their unusual breast localisation.

[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. In the authors' experience, the "UltraCision" cutting-coagulating device permits an atraumatic, bloodless and oncologically correct dissection. Using the double stapling technique, we succeeded in 60% of our middle- and low-third rectal cancer patients to perform a sphincter preserving low anterior resection. In 9 (28%) of the low third rectal cancer patients, preservation of the sphincter was possible with oncologically correct anterior resection and an ultra-low colo-anal anastomosis. Three anastomotic insufficiencies occurred, two of them healed on lotion-suction drainage, and one on the application of transient protective ileostomy. The literature data suggest a lower local recurrency rate after radical rectal cancer surgery, if total mesorectal excision is performed.

Laparoscopic fenestration of symptomatic solid spleen cyst with harmonic scalpel instrument.

The treatment of two operated solid splenic cysts has been reported by authors. Laparoscopic cyst fenestration has been demonstrated to be a useful alternative method to open surgery. The aim of the authors was to analyse the use of Ultracision Harmonic Scalpel in two spleen preserving procedures. Cysts were located in the superior and the anterior-inferior pole of the spleen. Cyst wall not covered by spleen tissues was removed, drain was left in the abdomen. In the demonstrating spleen cyst operation the advantages of HS instrument was the clean operating field, correct coagulation of cyst wall, short hospital stay. Authors believe that this new technology will make it easier and more desirable for surgeons to fenestrate symptomatic spleen cysts.

Laparoscopic hiatal reconstruction and use of harmonic scalpel instrument.

The method of laparoscopic repair of hiatal hernia is accepted in surgery. Usually associated with Nissen fundoplication which is the most commonly performed antireflux operation. Within a ten-year period authors have done 90 antireflux operations, 52 was laparoscopic procedures. (30 operations for GERD, 10 for hiatal hernia, 12 for the combination of both.) A patient was submitted to operation with large hiatal hernia. He was treated laparoscopic way with success and good results. The Ultracision Harmonic Scalpel instrument helped their operation in many ways, and provided correct bloodless preparation of cardiac region. The authors demonstrate our procedure and the use of the Harmonic Scalpel. Their patient were completely pleased with the results after discharge, they are still under regular control.

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. We'd like to demonstrate our experiences with a new device--Ultrasonically Activated Harmonic Scalpel-, witch was used at our operation for achalasia to make the cardiomyotomy. Between December 1993 and December 1996, 11 patients with esophageal achalasia underwent laparoscopic Heller's operation with Dor's antireflux procedures. In one patient we applied the Ultrasonically Activated Harmonic Scalpel (HS) to make the cardiomyotomy. The use of HS and results were evaluated. Application of the Harmonic Scalpel is effective for cardiomyotomy. It can be used more safe than electrocoagulation, because it cause less thermic lesion. It's easy to use at laparoscopic way. A perforation of the esophagus didn't occur. There was no intra-, or postoperative complications. After the operation the patient is free of complains. After our first operation, we have found, that Ultrasonically Activated Scalpel can be applied with safe and good results for the cardiomyotomy at laparoscopic operations for esophageal achalasia.

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. This study compares our original method of vessel control (at 10 cases, Group 1), to the Ultracision Harmonic Scalpel (at 10 cases, Group 2) Times for SGV division, estimated blood loss and intraoperative and postoperative complications were evaluated. In the favour for Group 2 a significant reduction was reached in the time required for division of SGV to mobilize the fundus. As the most common postoperative complication, the dysphagia concerns we found significant difference in the two groups and dysphagia was mild at Group 2. Application of HS provide safer, easier and faster division of SGV resulting significant savings of time and less prone to thermic trauma and recommended at LNF operations to avoid potential intra- and postoperative complications.

[Laparoscopic cholecystectomy. Initial experiences].

Between February 1991 and July 1991, 74 laparoscopic cholecystectomies were performed. The number of all cholecystectomies during this period was 168. Two surgeons performed the operations. Stone in the common bile duct, old age, acute cholecystitis, severe obesity and heart rhythm disorders were regarded as contraindications. The duration of the operation was 45-210 min. (mean 127 min). The intervention was diverted to open cholecystectomy in 2 instances (2.7%). Early postoperative complications were observed in 2 cases (2.7%): biliary discharge and bleeding. Reoperation was necessary in one patient (1.3%) because of bleeding. There was no operative mortality. The mean duration of hospitalization was 5.6 days, and the mean postoperative period was 2.7 days. It is considered that, laporoscopic cholecystectomy can be carried out only by specialists in both bile surgery and laparoscopic techniques, provided that all the personal and technical conditions necessary for traditional cholecystectomies are at hand. Both medically and economically, the laparoscopic cholecystectomy results attain or even exceed those of the traditional open technique.
