Abstract:
Objective To explore the efficacy difference of biliary stent combined with 125I seed intracavity irradiation and palliative biliary drainage in the treatment of obstructive jaundice caused by pancreatic head cancer. Methods The clinic date of 95 patients with pancreatic head cancer who underwent palliative surgery from June 2010 to June 2015 were analyzed retrospectively. 46 of the cases were treated with percutaneous biliary metal stent implantation combined with 125I seed intracavity irradiation (stent group), and the other 49 cases were treated with palliative biliary enterostomy (surgery group). The levels of jaundice, liver function, tumor size, survival time and hospitalization cost were compared between the patients before and after treatment. Paired t-test was applied for statistical analysis. Results Both the two treatment coulel effectively relieve jaundice and improve liver function. The mean TBIL of surgery group and stent group was (29.4±9.6) and (21.0±8.0)μmol/L after three months treanment, (40.3±11.0) and (24.4±9.6)μmol/L after six months treatment, respectively. Tumor maximum diameter of the two groups were (37.9 ± 4.5) mm and (33.5 ± 6.0)mm after three months treatment, (45.9 ± 5.0) mm and (37.0 ± 6.5) mm after six months, respectively. Each time point between them had statistical significance (t=-4.235,-5.476,-3.654,-6.702, P<0.05). The mean survival time was (12.83 ± 0.80) months in the stent group and (9.06±0.49) months in the surgery group, the difference was statistically significant (t=-3.49, P<0.01). The mean hospitalization cost of the stent group was (38 453.0 ± 7 282.0) yuan and the surgery group was (43 057.0 ± 7 667.4) yuan, the difference was statistically significant (t= 2.759, P<0.05). Conclusion For inoperable pancreatic head cancer patients, compared with palliative biliary enteric drainage, percutaneous biliary stent placement combined with 125I seed intracavity irradiation can effectively relieve biliary obstruction, improve liver function, inhibit tumor growth and prolong survival time.
