To compare the short-term clinical efficacy between prior and traditional approach of Henle trunk in laparoscopic right hemi-colectomy for right colon cancer.

Between June 2018 and June 2019, eighty cases who underwent laparoscopic right hemi-colectomy for right colon cancer in Gastrointestinal Surgery Department of Shanghai East Hospital Affiliated to Tongji University. According to the screening of operation videos, thirty-eight cases were given prior approach of Henle trunk (priority group) during the operation, while 42 cases (traditional group) were not given priority at the same time. A comparative, retrospective analysis was performed between the two groups in operative safety index and efficacy.

Age, gender, body mass index, tumor location, diameter of tumor, tumor stage were not significantly different between the two groups (P>0.05). As compared to the traditional group, priority group was associated with significantly less estimated mean blood loss [(62.89±29.31) mL vs. (86.90±33.89)mL, t=3.372; P=0.001], shorter operative time [(146.61±10.40) min vs. (159.21±21.60) min, t=3.270; P=0.002], and lower intraoperative vascular damage rate [5.3% (2/38) vs. 21.4% (9/42), χ²=4.396; P=0.036]. There were no significantly differences between these two groups in terms of postoperative complications, first exhaust time, initial defecaton time, drainage time, postoperative hospitalization time, quality evaluation of surgical specimens and results of pathological examination.

By using both two surgical approaches, radical resection of tumors could be achieved effectively in accordance with the principles of CME, and the operative effect was comparable. The prior process of Henle trunk in laparoscopic right hemi-colectomy for right colon cancer has advantages in less estimated blood loss, shorter operative time and lower intraoperative vascular damage rate. It is a safe and reliable treatment.
