Is there any difference between right hepatectomy and left lateral sectionectomy for living donors? as much you cut, as much you hurt?

BACKGROUND

The worldwide rising demand for cadaveric donors in liver transplantation is an important incentive for the development of alternative transplantation options, such as living donors. A precise evaluation of surgical complications is, therefore, considered to be an important issue in this setting.

AIM

Present a retrospective analysis of 126 living donors hepatectomies undertaken at our centre.

METHODS

From December 2002 to August 2009, 126 living donors were submitted to hepatectomy. Donors' complications were stratified according to Clavien's scoring system to compare the morbidity of right hepatectomy (RH) (Group 1) and left lateral sectionectomy (LLS) (Group 2).

RESULTS

Thirty-nine complications were observed in 35 patients. Sixty LLS, 3 left (LH) and 63 RH were performed. The complications were classified as: Clavien grade 1-11 (28.2%), grade 2-12 (30.7%), grade 3A-13 (33.3%), grade 3B-2 (5.1%) and grade 4A-1 (2.5%). When Group 1 (63 patients) and Group 2 (60 patients) were compared, there was no significant difference between the number of complications: 20 (31%) and 14 (23%), respectively (P > 0.3).

CONCLUSIONS

Hepatectomy for living donor liver transplantation (LDLT) was a safe procedure, regardless of the type of liver resection undertaken. We found no difference in morbidity between RH and LLS, which suggests that complications may occur despite the amount of liver retrieved.
