Laparoscopic Liver Resection can be an Effective Way in Obese Patients: A Single Center of 2-Year Experience.

OBJECTIVE: To evaluate the feasibility and safety of laparoscopic liver resection in obese patients, we compared the operative outcomes between obese and nonobese patients, also between laparoscopic liver resection and open liver resection of obese and nonobese patients. MATERIALS AND METHODS: A total of 86 patients suffering from liver resection in our department from January 2013 to December 2014 were divided into 3 groups: the obese patients group for laparoscopic liver resection, the nonobese patients group for laparoscopic liver resection and the obese patients group for open liver resection. Characteristics and clinic data of 3 groups were studied. RESULTS: Characteristics of patients and clinic data were equivalent between the 3 groups. The groups were well matched in age, sex distribution, and liver function (P>0.05). There were no significant differences in the operative time, estimated blood loss, time to oral intake, and postoperative hospital stay in the 3 groups. Tumor diameter of laparoscopic liver resection groups in obese patients was smaller than open liver resections groups in obese patients (P<0.05), but there were no obvious difference of tumor diameter in the laparoscopic liver resection groups of the obese patients and the nonobese patients. CONCLUSIONS: Obesity should not be seen as a contraindication for laparoscopic liver resection, which is a safe and feasible procedure for obese patients.

Laparoscopic Versus Open Resection for Liver Cavernous Hemangioma: A Single Center of 2-Year Experience.

OBJECTIVE: To evaluate the feasibility and safety of laparoscopic versus open resection for liver cavernous hemangioma (LCH). MATERIALS AND METHODS: A total of 131 patients suffering from LCH operated in our department between January 2013 and December 2014 were divided into 2 groups: 31 for laparoscopic liver resection (LR) and 100 for open liver resection (OR). RESULTS: Age, sex, presence or absence of chronic liver disease, tumor size, tumor location, type of resection, estimated intraoperative blood loss, operative time, length of postoperative hospital stay, morbidity, and mortality were equivalent between the 2 groups. There were no significant differences in estimated intraoperative blood loss between the LR and OR groups. The operation time of the LR group was longer than the OR group and the hospitalization expenses less than the OR group. However, the time of postoperative hospital stay and time of oral intake were shorter in the LR group than the OR group. The tumor of the LR group was smaller than the OR group. In liver function, alanine aminotransferase after operation of the LR group was lower than the OR group, the same as aspartate transaminase after operation. But there were no significant differences in total bilirubin after operation. CONCLUSIONS: Laparoscopic resection for LCH is a safe and feasible procedure as OR.
