A comparison study of left-hand three-port videoscopy, left-hand four-port videoscopy and standard four-port videoscopy in laparoscopic cholecystectomy.

UNLABELLED: A comparison study of left-hand three-port videoscopy, left-hand four-port videoscopy and standard four-port videoscopy in laparoscopic cholecystectomy AIM: Reviewing the recent publishments on the safeness and practicality of three-port cholecystectomy we aimed to introduce the results of cholecystectomy that were performed by the primary surgeon's left hand videoscopy application through three ports.

MATERIAL AND

METHODS

The data of 60 total laparoscopic cholecystectomy patients were retrospectively anaylsed. 20 patients underwent three-port laparoscopic cholecystectomy with videoscopy using the primary surgeon's left hand, 20 patients underwent four-port laparoscopic cholecystectomy, again with left hand videoscopy application, and the other 20 patients underwent standard four-port laparoscopic cholecystectomy by a more experienced surgeon. Kolmogorov-Smirnov test was used to evaluate the distribution normalization of parameters. To compare the parameters of multiple groups; one-way ANOVA-Tukey HSD was used for normal distributed, the Kruskal-Wallis test was used for abnormal distributed values. Pearson's chi-squared test was used for categorical values. The results with p-values of less than 0.05 were accepted as statistically significant.

RESULTS

There were no differences between the groups for preoperative (p=0.456) and perioperative clinical characteristics (p=0.918), mean operation time (p=0.855), perioperative complication (p=0.153), conversion to open surgery (p=0.362) and the need for first assistant surgeon (p=0.235). However, the need for second assistant surgeon (p=0.017), assistant nurse (p=0.014) and fourth tool usage (p=0.000) were significantly lower in the three port group.

CONCLUSION

Left-hand videoscopy in three-port laparoscopic cholecystectomy is reliable and effective as the conventional techniques and cheaper than conventional techniques. It's easily applicaple and learnable for experienced surgeons.
