Parenchyma Transection

Background: Several devices are available for liver parenchyma transection (LPT). The aim of this study was to compare the Ultracision Harmonic scalpel (UHS) with the Cavitron Ultrasonic Surgical Aspirator (CUSA) among patients who underwent hemi-right hepatectomies (RH) to homogenize transection areas. Methods: From September 2012 to June 2015, 24 patients who underwent the UHS surgery approach were matched with 24 patients who underwent the CUSA transection procedure for RH using propensity score matching. Results: Total operative time (TOT) was shorter in the UHS group, 240 minutes (range 172.5-298.8) versus 330 minutes (range 270-400) in the CUSA group ( P = .0002). The occurrence of hepatopathy (odds ratio = 17; 95% confidence interval = 1.02-230) and the use of the CUSA device (odds ratio = 8; 95% confidence interval = 0.98-77) were associated with a TOT exceeding 300 minutes in multivariate analysis ( P = .05). Conclusions: The UHS is a safe and effective method of LPT as compared to the use of the CUSA system. TOT is statistically decreased.

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%).
