[The role of sonography in laparoscopic cholecystectomy]. / A sonographia szerepe a laparoscopos cholecystectomiában.

Between January 1991. and December 1993. in the 3rd Surgical Department of Semmelweis Medical University 735 laparoscopic cholecystectomies were performed. Intraoperative and postoperative complications occurred in 2.7% and 3% respectively. Conversion to open procedure was necessary in 8.4%, reintervention was indicated in 2.3%. The total occurrence of common bile duct stones was noticed in 1.6%. The incidence of bile duct injury 0.54%. The role of sonography in laparoscopic cholecystectomy is multiple: patient-selection, diagnosis of complications, ultrasound guided interventions in cases of complications, follow up of patients. The authors compared in 419 cases the preoperative sonography with the intraoperative finding. The risk of intra- and postoperative complications was significantly higher if the stone was impacted into the cystic region, if the gallbladder was enlarged, especially with wall-thickening and signs of acute inflammation. The fibrosis and scarring of gallbladder represent an increased risk as well. The accuracy in estimation of common bile duct dilatation is very high, but in the judgement of bile duct stones there was a high false positive rate. In spite of this, the echography is very well applicable for patient-selection. In the patient group selected with positive sonographical finding for open cholecystectomy, the prevalence of common bile duct stones was 25%, compared with 1.6% in laparoscopic group. In cases of postoperative complications the diagnostic sonography may be followed with ultrasound-guided puncture and/or drainage.

Surgical relations of Crohn's disease and the frequency of recurrence.

There is no disease that would have as many and variable complications as Crohn's disease. One of the most common complications is bowel obstruction which can be caused by the angulation of the bowel or by inflammation, or by formation of granulation tissue (32.3%). Very common is the formation of fistulae amongst the bowels involved and other abdominal organs, and also entero-cutaneous fistulae occur frequently (11.3-14.4%). The frequency of complications is increasing with the duration of the illness. If they are life-threatening, only surgical treatment can help. Surgical treatment is also indicated when conservative treatment fails. The most commonly used surgical interventions are bowel resection and, recently, the plasty of stenotic areas. The operative mortality (3.7%) is influenced by the length of the disease and by the numbers of complications. Recurrence is very common in Crohn's disease (30.1-34.9%). The mortality rate of the second operation is 17.5%. The prognosis is usually poor because recurrence can occur years after the primary operation. In Hungary, the frequency of surgically treated patients with Crohn's disease is low, they count for 0.06% of all general surgical operations.

Early complications of gastric resection.

Analyzing the patient material of 506 patients with gastric resection, authors deal with the early complication of resection, its diagnosis and treatment. They review the complications, their frequency and mortality in their own material. After operations made for tumour, complications occurred more frequently than after interventions because of ulcer. Total mortality was 10.2%. In order to reduce mortality they call attention to the possible prevention of complications and their careful management.

[Pseudosarcoma of the esophagus]. / Az oesophagus pseudosarcomája.

Authors describe pseudosarcoma, a rare esophageal tumour in a 52-year-old male patient. The tumour of complex histological appearance has characteristic macroscopic, microscopic and clinical features. Although its histogenesis is unclear, it can be well distinguished from the real carcinosarcoma and represents an independent class of tumours.
