Abstract:
ObjectiveTo investigate the efficacy of laparoscopic spleen-preserving hilar lymph nodes dissection based on splenic hilar vascular anatomy.MethodsFrom July 2010 to March 2011,the clinical data of 39 patients with advanced proximal gastric cancer who underwent laparoscopic spleen-preserving hilar lymph nodes dissection at the Union Hospital of Fujian Medical University were retrospectively analyzed.Different types of vascular anatomy were analyzed,and different methods of lymph node dissection in the splenic hilus were adopted accordingly.ResultsThe operation was successfully performed on all the patients,with no conversion to open surgery or splenectomy due to splenic vascular or parenchyma injury.There were 4 types of splenic artery running,including type Ⅰ (25 patients),type Ⅱ (8 patients),type Ⅲ (4 patients) and type Ⅳ (2 patients).There were 2 types of the end branches of splenic artery,including concentrated type (28 patients) and dispersion type (11 patients).The splenic lobial vessels of all the patients were anatomically classified and divided into 4 types,including a single branch of splenic lobial vessels in 3 patients,2 branches in 24 patients,3 branches in 11 patients and multibranches in 1 patient.The mean number of short gastric vessels was 3.2 ± 1.4 (range,2-6).The time for dissection of the lymph nodes in the splenic hilum,number of lymph nodes dissected in the splenic hilum,volume of operative blood loss,duration of hospital stay and incidence of complications were ( 30 ±7)minutes,2.8 ±2.1,(20 ±7)ml (range,0-55 ml),(10 ± 1) days and 10％ (4/39).All patients were followed up until March,2012. One patient had hepatic metastasis,and no patient died postoperatively.ConclusionFamiliar with the variation of splenic hllar vascular anatomy is helpful in mastering and promoting laparoscopic spleen-preserving hilar lymph nodes dissection.
