摘要
背景与目的:胰十二指肠切除术后的合并症发生率仍然较高。术前胆道引流可以改善肝功能,但对于恶性低位胆道梗阻患者行胰十二指肠切除术术前肝功能的具体影响,以及肝功能指标在手术前后的变化情况,目前仍未见报道。本研究分析术前胆道引流对恶性低位胆道梗阻行胰十二指肠切除术患者术前肝功能的影响,以及肝功能指标在手术前后的变化及分析其预后。方法:收集98例行胰十二指肠切除术恶性低位胆道梗阻患者[总胆红素(totalbilirubin,TB)>85μmol/L]的临床资料,分析肝功能指标和胆红素之间的相关性、手术前后肝功能的变化、以及分析预后;按照术前是否胆道引流分为减黄组、未减黄组,分析术前胆道引流对肝功能指标的影响,按照术后是否发生并发症分为有、无并发症组,分析并发症对术后肝功能变化的影响。结果:γ-谷氨酰转移酶(γ-glutamyltransferase,GGT)与TB呈正相关关系(r=0.368,P<0.001),而碱性磷酸酶(alkaline phosphatase,ALP)与TB无相关性。减黄组术前胆道引流后,TB、直接胆红素(direct bilirubin,DB)、丙氨酸转氨酶(alanine aminotransferase,ALT)、ALP、GGT分别由术前的(266±119)μmol/L,(160±75)μmol/L,(161±88)U/L,(508±276)U/L,(537±417)U/L减至术后的(184±115)μmol/L,(112±67)μmol/L,(99±90)U/L,(319±145)U/L,(203±176)U/L,差异有统计学意义(P<0.05),但减黄前后天冬氨酸转氨酶(aspartate aminotransferase,AST)的变化不显著。全组患者ALT、AST、GGT、ALP术后第7天达最低值,第14天轻度上升;术后7d时,TB、DB在有并发症组为(152±68)μmol/L,(80±57)μmol/L,较无并发症组的(101±77)μmol/L,(58±45)μmol/L升高,两组差异有统计学意义(P<0.05),白蛋白(albumin,ALB)在有、无并发症组分别为(36.2±4.7)g/L,(38.6±5.2)g/L,两组差异有统计学意义(P<0.05)。减黄组中位生存期19.2个月,未减黄组中位生存期16.4个月,两组相比差异无统计学意义(P=0.458)。结论:GGT更能反映恶性低位胆道梗阻的程度。术前胆道引流可以有效的改善肝功能,并发症的出现影响恶性低位胆道梗阻行胰十二指肠切除术患者术后短期内的黄疸以及肝功能的改善。术前减黄对远期预后无影响。
BACKGROUND & OBJECTIVE: Pancreaticoduodenectomy can cause a high morbidity of postoperative complications. Preoperative biliary drainage can improve liver function. However, the effect of preoperative biliary drainage on preoperative liver function of the patients underwent pancreaticoduodenectomy for malignant obstructive jaundice in the low bile duct has seldom been reported. This study was to investigate the perioperative liver function changes and prognosis of the patients. METHODS: Data of 98 patients, with total serum bilirubin level of over 85 μmol/L and underwent pancreaticoduodenectomy for malignant obstructive jaundice in the low bile duct, were collected. The correlation of liver function to serum bilirubin level, perioperative liver function changes, the impacts of preoperative biliary drainage and postoperative complications on postoperative liver function, and prognosis were investigated. RESULTS. The index of y-glutamyltransferase (GGT) was positively correlated to total bilirubin (TB) (r=0.368, P〈0.001), but alkaline phosphatase (ALP) was not. Preoperative biliary drainage significantly reduced TB from (266±119) μmol/L to (184±115) μmol/L, DB from (160±75)μmol/L to (112±67)μmol/L, ALP from (161 ±88) U/L to (99± 90) U/L, alanine aminotransferase (ALT) from (508±276) U/L to (319±145) U/L, and GGT from (537±417) U/L to (203±176) U/L (all P〈0.05), but did not reduce aspartate aminotransferase (AST) significantly. ALT, AST, GGT, ALP decreased to the lowest values on Day 7 after operation, but increased slightly on Day 14. On Day 7 after operation, TB and DB were significantly higher and albumin (ALB) was significantly lower in the patients with postoperative complications than in those without complications E(152±68) μmol/L vs. (101±77) μmol/L, (80±57) μmol/L vs. (58±45) μmol/L, and (36.2±4.7) g/L vs. (38.6±5.2) g/L, all P〈0.05]. The median survival time was 19.2 months in the patients underwent preoperative biliary drainage and 16.4 months in the patients didn't undergo preoperative biliary drainage (P=0.458). CONCLUSIONS: GGT can sensitively reflect the extent of malignant obstruction in the low bile duct. Preoperative biliary drainage can improve liver function-effectively. Postoperative complications has adverse effects on the improvement of postoperative jaundice and liver function in a short time after operation. Biliary decompression has no effects on the prognosis.
