Background:
Laparoscopic right hemicolectomy (LRC) with a principle of D3 lymphadenectomy seems to be appropriate in treatment of right-sided colon cancer (RCC). This study aimed to evaluate clinical efficacy of superior mesenteric artery (SMA)-guided LRC (SLRC) for RCC patients.
Patients And Methods:
Data for RCC patients with radical resection were retrieved from our database and electronic medical records (January 2010 to December 2014). Patients undergoing SLRC procedure were compared with those undergoing conventional laparoscopic right hemi-colectomy (CLRC), with a match ratio of 1:2 for group balance. Perioperative and long-term outcomes were compared between two groups.
Results:
In sum, 102 matched patients were selected, with a median follow-up of 32 (range, 3-68) months. The mean operative time was significantly reduced in the SLRC group compared to the CLRC group (206.9 vs 240.0 minutes, P=0.007), with increased incidence of postoperative complications observed (14.7% vs 8.8%, P=0.499). Average length of stay after surgery (7.4 vs 8.0 days), estimated blood loss (85.3 vs 105.4 mL), number of harvested (28.4 vs 28.2) and positive (0.6 vs 0.9) lymph nodes, and overall costs ($4826.9 vs $4874.6) were comparable between two groups (P>0.05). The 3-year disease-free survival rate (89.4% vs 92.1%, P=0.840) and overall survival rate (93.0% vs 83.1%, P=0.273) were similar in both groups. Older age (≥65 years, P=0.049) and advanced tumor stage (≥II, P=0.009) were independent risk factors of recurrence.
Conclusion:
The perioperative and oncologic outcomes of SLRC were not superior, but comparable to CLRC. SMA-guided dissection was a feasible surgical approach in treatment of RCC.
