Aim of the study. To estimate an influence of the Cavitron ultrasonic surgical aspirator (CUSA) on intraoperative blood loss. Material and methods. An analysis of 185 cases of extensive liver resections in patients for colorectal liver metastases has been performed. All patients were assigned to CUSA group (n = 56) or clamp crashing group (n = 129). Patients from the first group received regional FOLFOX6 or FOLFOX6 + bevacizumab chemotherapy. Preoperative chemotherapy did not performed for second group of patients. Results. Liver transection with CUSA did not lead to the decline in intraoperative blood loss (p = 0.35). Conclusion. Median intraoperative blood loss was 1065 and 1180 ml respectively. Method for liver transection did not lead to the decline in intraoperative blood loss (p = 0.35). Intraoperative blood loss increases from standard to extensive liver resection (p = 0.0007). Resection of contralateral blood lobe metastases did not lead to statistically significant increase in blood loss as compared with standard mode of the operation (p = 0.005).

The Cavitron Ultrasonic Surgical Aspirator (CUSA) may be used to remove mucosa of organs of the gastro-intestinal tract. A histological analysis was performed on gallbladders treated with a CUSA-mucosectomy to assess the extent and degree of mucosectomy and to evaluate parietal damage. The histological studies performed on three specimens of chronic cholecystitis revealed a complete mucosectomy except in areas where Rokitansky-Aschof sinuses were present. There was no evidence of parietal damage. The CUSA may be used to remove the mucosa of gallbladders without injury to other layers, and may have a potential application in procedures such as mucosal cholecystectomy.

Abstract Between January 1984 and December 1990. 65 intramedullary spinal cord tumors were diagnosed and operated on. In this series, all patients underwent magnetic resonance imaging investigations and were operated on with the Cavitron ultrasonic surgical aspirator whenever necessary. Major surgical difficulties have been found in patients previously treated by radiotherapy with or without biopsy. We found magnetic resonance imaging to be a highly sensitive imaging procedure and the method of choice for visualizing tumors within the spinal cord. Nevertheless, accurate diagnosis may only be suggested by magnetic resonance imaging, rather than made definitively. Surgery is necessary in every case in order to obtain a definite diagnosis. Radical surgery can be performed when a plane exists between the tumor and the normal spinal cord: biopsy or debulking with the Cavitron ultrasonic surgical aspirator should be performed when the tumor is infiltrative. We have performed 33 so-called total resections, 22 partial resections, and 10 biopsies, among which 5 were performed on lipomas. Surgical results were assessed at 3 months after surgery, showing 35 improvements (53%), 24 stabilizations (37%), and 6 deteriorations (10%).
