Postoperative Nutritional Assessment of Laparoscopic Versus Open Partial Hepatectomy.

ABSTRACT

BACKGROUND/AIM: No studies have investigated the advantage of laparoscopic hepatectomy (LH) compared with open hepatectomy (OH) from a nutritional perspective. This study aimed to compare the postoperative nutritional status between LH and OH. PATIENTS AND METHODS: A total of 186 patients who underwent partial hepatic resection for liver tumors were analyzed retrospectively. We compared perioperative variables between LH and OH. The nutritional status was assessed using serum albumin (Alb) and rapid turnover protein concentrations. We investigated risk factors for postoperative malnutrition using univariate and multivariate analyses. RESULTS: The LH group, compared with the OH group, had a significantly shorter operative time (239 vs. 344 min, p<0.03), less intraoperative blood loss (100 vs. 343 g, p<0.01), and a shorter length of postoperative stay (8 vs. 11 days, p<0.01). Postoperative serum Alb and prealbumin concentrations in the LH group were significantly higher than those in the OH group (3.4 vs. 3.2 g/dl, p<0.01; 15.0 vs. 12.0 mg/dl, p=0.02, respectively). The multivariate analysis showed that OH (p=0.02) and hepatocellular carcinoma (p<0.01) were significant and independent risk factors for postoperative malnutrition. CONCLUSION: LH may be superior to OH in terms of the postoperative nutritional status, intraoperative blood loss, and length of postoperative stay.
