Complication rate, duration of operation, insertion of 4th port, converting laparoscopic method to open, duration of hospital admission, early return to work and need of analgesics were studied in patients with three ports laparoscopic cholecystectomy (LC) vs. four ports LC. Results: A total of 200 patients who had removal gall bladder laparospically, three-port LC were performed in 117 (58.5%) patients and four-port LC was performed in 83 (41.5%) patient. There was no significant difference with respect to complication rate, converting to open technique and duration of operation were comparable to four ports LC. One patient required 4th port in left hypochondrium for liver retractor to retract enlarged left liver lobe.
