[Prevention of the anastomosis dehiscence following low anterior rectal resections].

Authors analyse 106 patients that were operated in their department by Dixon's method, in retrospective study. They analyse indications for operations, lesions distance in rectum, endosonographic and CT findings. Basic principles of the operation technique are adequate blood flow, sufficient colon mobilization and tightness of the anastomosis being supplemented with transanal pertubation. Out of early complications anastomosis dehiscence appeared in 6 patients (e.g. 5.6%) out of which 4 were treated conservatively and 2 were being reoperated on (by axial ileostomia and drainage). In discussion different opinions on preoperative preparation, neoadjuvant therapy, presacral drainage, transanal pertubation and other decompressive techniques are anticipated.

[Giant retroperitoneal liposarcomas].

According to literature liposarcomas account to less than 0.1% of all human tumors, 13% of which are localiced retroperitoneally. Authors describe two cases of giant retroperitoneal liposarcoms treated in their department. CT findings and the course of the disease discussed. Conlusively authors remark of high probability of microscopical residual disease with need of patients' follow up with eventual reoperation and adjuvant radiotherapy.

[Rupture of the laparotomy incision and its suture using Ventrofilm].

The authors analyze a group of patients operated at their department with the objective to assess factors involved in the development of ruptures of laparotomic wounds and to evaluate resuture by suspended ventrofil stitches. In the whole group of 5554 laparotomized patients the incidence was 0.4%, in 1685 urgently operated patients the incidence was 0.9%. In the discussion the authors analyze some factors of rupture and consider the personality of the surgeon an important factor. For resuture suspended sutures using Ventrofil proved useful. The problem of suspending suture in primary operations in risk patients is still doubtful similarly as the closure of the laparotomic wound in abdominal compartment syndrome.

[Modern trends in the treatment of diffuse peritonitis].

The authors describe new approaches to the treatment of diffuse peritonitis, using the Mannheim Peritonitis Index scoring system. Depending on the score, the authors determined the types of additional surgical procedures such as "sipping drainage", laparostomy and repeated laparotomies.

[Complications of colostomy--how to avoid them].

According to data in the literature complications develop in association with colostomy in 20-66% of patients, occlusion of the colostomy occurs in 10-17%. The authors analyze their own group of 122 patients where in 1994-1998 a colostomy was made. Sixty-two patients were operated with developed ileus, 19 colostomies were later abolished and the passage per vias naturales was reconstructed. The authors recorded 38.5% complications, they were most frequent in axial transversostomies and sigmostomies, wound infections were most frequent. For prevention of complications the authors emphasize that stricter indications for colostomy should be used. The same applies to the selection of the type and site of colostomy and exact surgical technique, ATB prophylaxis and lavage, use of modern stomic appliances, perspectives of using the laparoscopic technique.

[Carcinoma of the gastric stump].

The authors present a group of seven patients operated in 1992 to 1996 on account of carcinoma of the gastric stump. All patients had a Billroth II resection at the age of 52 to 77 years. The mean period after resection was 21.3 years. In three patients total gastrectomy was made, in three patients subtotal resection and only in one patient a palliative anastomosis. The mortality within 30 days was 0%. The survival period was not evaluated as the data were incomplete. In the discussion the authors mention factors pertaining to the predisposition and pathogenetic mechanisms of development of the disease. For prevention gastroenterological dispensarization is necessary and preference of a gastroenteroanastomosis with a minimal alkaline reflux (Roux-Y, Eiselberg a anastomosis).

[Right-sided pneumothorax--a complication of laparoscopic cholecystectomy].

In a 49-years old woman cholecystolithiasis was confirmed by sonography and she was admitted for laparoscopic cholecystectomy. During the operation right-sided pneumothorax developed as a result of the injury of diaphragma by monopolar electrocautery. Operation was converted and the injury was treated by continuous suture. Carbon dioxide was spontaneously resorbed from thoracic cavity during the 5 days following the operation without tube thoracostomy. The operating wound was healed per primam and the patient was discharged on the 14th postoperative day.

[31P NMR spectroscopy in acute experimental pancreatitis].

In order to investigate the changes in phosphoglucose metabolism in acute experimental pancreatitis, the authors utilized the measuring cell NMR spectroscopy. The experimental pancreatitis had been evoked by both the method of ligature of lateral pancreas ducts and that of the duodenal blind loop. These methods evoke a morphological response, namely edematous and necrotizing pancreatitis. Gradual reduction of macroergic phosphate binds and augmentation of anorganic phosphates represent the principal change in NMR spectrum. The clinical picture provides evidence of the exhaustion of highly energetic phosphate compounds which are necessary for the maintenance of integrity of the pancreas tissue in acute experimental pancreatitis. The discussion includes the possibilities and limitations of the NMR spectroscopy.
