Background : Laparoscopic cholecystectomy has advantages over the open procedure for postoperative pain .
However , a systematic review of postoperative pain management in this procedure has not been conducted .
[Gasless versus conventional laparoscopic cholecystectomy. A randomized trial with regard to technical problems, postoperative course and convalescence].
INTRODUCTION The positive CO2 pneumoperitoneum needed to create the working space for laparoscopic surgery may induce pathophysiological changes . Concern about these changes has led to the introduction of a gasless technique . The aim of the present study was to compare the gasless CLC and GLC with regard to exposure , technical problems , operation time , postoperative pain , clinical course , and convalescence . MATERIAL AND METHODS Fifty consecutive patients with symptomatic gallstones were r and omised to  conventional ( CLC ) or gasless laparoscopic cholecystectomy ( GLC ) , with special reference to overall patient satisfaction , technical difficulties , duration of surgery , postoperative pain , and recovery . RESULTS The overall exposure of the operative field was poorer in the GLC group , whereas the duration of surgery , steps involved in the cholecystectomy technique , length of hospital stay , and postoperative pain score did not differ significantly . The period to return to normal activity was significantly shorter in the GLC group , six days compared to 8.5 days in the CLC group ( p < 0.05 ) . No differences were found in terms of fatigue , dizziness and nausea , and overall satisfaction with the outcome . DISCUSSION This study shows that convalescence is significantly shorter after laparoscopic cholecystectomy by the gasless technique than by the conventional CO2 technique . However , exposure of the operative field was less than optimal with the gasless technique
