Random Comparison of LigaSure and Disposable Staples for Laparoscopic Surgery

The purpose of this research is to compare two different standard of care surgical methods for the following large bowel (colon) procedures: laparoscopic right colectomy, total colectomy, and left colectomy. The study will compare electrocautery, used with surgical clips and/or surgical staplers, and the Ligasure vessel sealer. The investigators will be looking at which procedure is faster and more cost efficient and the investigators will calculate hospital expenses for the two groups to make comparisons.

本研究旨在针对腹腔镜右半结肠切除术、全结肠切除术及左半结肠切除术这三类大肠（结肠）手术术式，对比两种不同的标准治疗外科方案。本次研究将对比分别配合手术夹和/或手术缝合器使用的电灼术（electrocautery）与结扎速血管闭合器（Ligasure vessel sealer）。研究者将评估哪种方案更具手术速度优势与成本效益，并通过计算两组受试者的住院费用以开展对比分析。
