INTRODUCTION-This study was undertaken to compare the clinical outcomes of laparoscopic cholecystectomy (LC) done by either using surgical energy i.e. energized dissection (ED) or without using surgical energy i.e. by cold dissection (CD) .
METHODS AND PROCEDURES -A prospective randomized control study (September 2008- June 2013) of consecutive unselected consenting candidates for LC performed on index hospitalization without any exclusion (except uncorrected coagulopathy & unfitness for general anaesthesia). The study population was randomized into ‘Control Group’ (LC with ED) and ‘Study Group’ (LC with CD). A standard perioperative clinical management protocol/ pathway for day care LC was followed. Standard technique of LC for the control group (ED) and our published technique of LC with CD for the study group (CD) were followed. All the LC candidates were operated in same operative complex with same surgical team & same set of instruments. Energy sources were available as ‘stand by’ / rescue for the CD group if needed.
|Perioperative||Technical difficulty, Hemodynamic instability, Conversion, Blood transfusion (BT), Injury to Common Bile Duct(CBD)/ hollow viscera|
|Postoperative||Peritonism for >24 hr (paralytic ileus); shoulder tip pain for >24 hrs; biliary leak; re-intervention; re-hospitalization for any complication|
|Other data||Length of hospital stay (LOS), Self-care ability after 1 day, Resumption of normal activity within 5 days, any adverse event in 3 months, mortality|
Prospectively collected data analysed using SPSS-17 version. Qualitative data was compared using chi-square and quantitative data was compared using T-test and P-value < 0.05 was considered significant.
|Age, mean (SD) years||44.4 (14.4)||46.4 (13.4)||0.04|
|Male= n (%)|
|Grade of inflammation, n (%)|
|Comorbidity n (%)|
|Pre –operative ERCP, n (%)||35 (9.7)||42(10.9)|
Complications n (%)
Post- operative Bile leak
|LOS, mean (SD) days||1.6 (1.03)||1.35(1.2)||<0.001|
There was no technical difficulty in either group & no need of ‘rescue’ use of surgical energy in the CD group. All un-complicated cases could be discharged as ‘day care’. Except for the complications given in the table above, other adverse study points were not observed in either of the groups.
Coclusion- There was no statistically significant difference in clinical outcomes of LC done either with ED or CD. However occurence of post-operative biliary leaks & hemorrhage necessitating blood transfusion in the ED group(precluding discharge as ‘day care’) requires further studies to look for any association of adverse outcomes with the use of ED in LC.
