ABSTRACT
BACKGROUND/AIMS: This study assessed the short term results of laparoscopic colorectal resection for high risk patients. METHODOLOGY: Five hundred and fifty seven consecutive patients underwent an elective laparoscopic colorectal cancer resection by the same surgical team between April 2007 and December 2010. No risk patients in ASA class 1 (Group N, n=222), low risk patients with the systemic disease under the control in ASA class 2 and 3 (Group L, n=320), high risk patients with severe comorbidities in ASA class 4 (Group H, n=15) were respectively compared. RESULTS: The median blood loss count was significantly higher than the other group (N: 26 g, L: 22 g) in group H (59 g; p<0.05). On the other hands, the less lymphadenectomy was performed and a reconstruction with anastomosis was denied in group H. The incidence of postoperative complications was not significantly different in each group (N: 12%, L: 18%, H: 26%; p>0.05). There was the significant difference of the incidence with systemic complication (respiratory failure, ascites and delirium) in group H. The median postoperative hospital stay was not significantly different in each group (POD7; p>0.05). Hospitalization death occurred in three patients (0.5%) by uncontrollability of the systemic disease, two patients in group L and one patient in group H. CONCLUSIONS: Laparoscopic colorectal resection for high risk patients was performed safely without increasing complications and postoperative hospital stay.

We analyzed the relationship between Onodera's prognostic nutritional index(PNI), classified by serum albumin level, lymphocyte level, and clinicopathological features, in 46 patients with unresectable or recurrent colorectal cancer being treated with chemotherapy.Onodera 's PNI was distributed between 29.7 and 56.1(average 45.4±6.8 ).Onodera 's PNI showed a significant correlation with performance status and surgery before chemotherapy(p=0.002 and 0.002, respectively).Next, all patients were divided into two groups according to their Onodera's PNI values, based on the receiver operator characteristic curve.We found that Onodera's PNI showed a significant correlation with overall survival times(median survival time, 548 days(Onodera's PNI<47.8 ), 902 days(Onodera's PNI≥47.8 ), p=0.00065 ).This PNI could be a prognostic factor and a very useful objective screening tool for assessing the nutritional condition of those with unresectable or recurrent colorectal cancer being treated with chemotherapy.
