title: [Surgical treatment of acute destructive pancreatitis with low frequency ultrasound].
abstract: Energy of low-frequency ultrasound was used for removal of necrotic foci in the pancreas and parapancreatic tissue before septic complications. Studies of the pancreas of patients who had died of pancreonecrosis permitted to select optimum configuration of working butt of wave-wire. Experimental studies (22 dogs) demonstrated high efficacy of this method: necrotic foci were removed completely with little capillary bleeding; microscopic study showed that wound process had reparative character with minimum inflammation. Clinical study was carried out in 172 patients with acute destructive pancreatitis. In 139 patients traditional methods were used: left-sided resection of the pancreas, abdominization of the pancreas, staged sequestrectomies. Lethality in this group was 46.7%. Thirty-three patients underwent ultrasonic necrosequestrectomy, lethality was 30.3%.
