RESUMO
On the basis of 20 years' experience, the authors present the immediate and long-term results of operative treatment of Zenker's diverticulum. Comparison of two methods of surgery - diverticulopexia (in 21 patients) and excision (in 16), both associated with upper esophageal sphincter myotomy - shows good immediate and longterm results (from 1 to 19 years), with disappearance of symptoms (dysphagia) in all patients. There was no perioperative mortality. Postoperative complications were most commonly of pulmonary origin and were observed in a third of patients in both groups. In two patients from the group treated with excision, a leak from the suture line occurred, which healed spontaneously. These two patients had transient dysphagia in the postoperative period. On the basis of this analysis, the authors conclude that diverticulopexia is a safer surgical procedure than excision, giving less complications and a very good long-term functional result.

The so-called learning factor has been disregarded for many years in analyzing the causes of surgical complications and post-operative mortality; it is also the case for OLT. In our center until April 2003, 209 OLT were performed in 196 patients. We evaluated the impact of experience of the transplantation team on the outcomes of liver transplantation. Thirty-four patients died (mortality rate, 16%) and 1-year survival rate, 64%. Mortality rates varied during different periods of observation due to increasing experience of the transplantation team. The causes of mortality were assessed for a series of 34 patients: it was 75% at the beginning of transplantation procedures while recent deaths have not recently exceeded 10% of cases.

From 1989 to 1999, 43 orthotopic liver transplantations (OLT) in 40 patients (3 retransplantations) were performed in our Department. The most common indications for OLT were noninflammatory, primary cholestatic liver diseases and postinflammatory liver cirrhosis. Fourty OLT's were done for elective indications, three--on emergency basis, because of fulminant liver failure. The majority of transplantations was performed with classical technique with the excision of retrohepatic vena cava and routine use of the extracorporeal veno-venous bypass. Only in 4 patients the piggyback technique was used and performed without temporary portocaval anastomosis. All 3 patients transplanted for fulminant liver failure died in the perioperative period. Twenty four patients are still alive and well, the longest period of observation exceeding 5 years.
