Objective: The use of mini-instruments in laparoscopic cholecystectomy (LC) was
more technique-demanding and manpower-demanding than conventional LC. The
feasibility of using a vocally controlled manipulator AESOP (Automated Endoscopic
System for Optimal Positioning) to assist mini-LC, however, has not been established
as yet. This study compared the outcome of AESOP-assisted mini-LC (A-MLC) with
that of human-assisted mini-LC (M-MLC).
Methods: The outcomes of 28 patients undergoing M-MLC were compared with
those of a subsequent series of 28 patients undergoing A-MLC. Patient demographics
including surgical indications, body mass index, and peri-operative parameters such
as preparation time, operation time, hospital stay, and surgical complications were
compared between the two groups.
Results: The patient demographics were similar between the two groups. MLC was
successfully performed in 48 patients. Three patients in the A-MLC group and five
patients in the M-MLC group had to change one of the 2 mm working ports to a 5 or
10 mm working port to complete the procedures. Both approaches resulted in good
recovery. The mean preparation time in A-MLC (22.93 10.50 minutes) was shorter
than that in M-MLC (25.21 8.38) minutes, but the difference was not statistically
significant. The mean operation time in A-MLC (43.39 20.45 minutes) was
significantly shorter than that in M-MLC (64.46 26.78 minutes). No biliary tract
complications were recorded in either group. The length of hospital stay, resumption
of diet, and the use of narcotic analgesics were not significantly different between the
two groups.
Conclusions: As compared with a human-assisted surgery, AESOP facilitated the
performance of mini-laparoscopic cholecystectomy by providing a stable camera
platform and avoiding unwanted movement during the laparoscopic procedure. |
