Randomized Controlled Trial Comparative Study Clinical Trial
Randomized comparison between low-pressure laparoscopic cholecystectomy and gasless laparoscopic cholecystectomy.
Laparoscopic cholecystectomy using low-pressure pneumoperitoneum (8 mmHg) minimizes adverse hemodynamic effects, reduces postoperative pain, and accelerates recovery. Similar claims are made for gasless laparoscopy using abdominal wall lifting. The aim of this study was to compare gasless laparoscopic cholecystectomy to low-pressure cholecystectomy with respect to postoperative pain and recovery. ⋯ Gasless and low-pressure laparoscopic cholecystectomy were similar with respect to postoperative pain and recovery. The gasless technique provided inferior exposure and the operation took longer, but the technique may still have value in high-risk patients with cardiorespiratory disease.

In most cases, myasthenia gravis (MG) and thymoma require complete removal of the thymus gland and resection of the pericardial fatty tissue. There is some debate however, over which surgical approach is best for thymectomy. We have developed a new technique for complete thoracoscopic thymectomy. ⋯ While the short-term improvement of MG after this procedure was comparable to that seen with conventional surgery, the short- and intermediate-term quality of life was much better. The preliminary results of thoracoscopic thymectomy appear to be excellent for both patients and neurologists. A prospective randomized trial has been designed to compare thoracoscopic thymectomy with the gold standard of median sternotomy for thymectomy.
