改良胆肠袢式吻合术的疗效分析

Objective To evaluate the long-term efficacy of modified loop choledochojejunostomy (MLC). Methods The clinical data of 259 patients who had underwent choledochojejunostomy in First Affiliated Hospital of Sun Yat-Sen University from January 2000 to December 2006 were retrospectively analyzed. Of all the patients, 130 underwent MLC (MLC group) and 129 underwent Roux-en-Y choledochojejunostemy (RYC, RYC group). The changes in incidence of cholangitis and liver function between the 2 groups were compared. All the data were analyzed by t test, chi-square test or Fisher exact probability. Results The levels of alaninetransa-minase and alkaline phosphomonoesterase were (63±42) U/L and (147±147) U/L in MLC group, and (84±52)U/L and (256±201)U/L in RYC group, with statistical difference between the 2 groups (t=1.634, 1.655, P>0.05). The level of gamma-glutamyl transferase in MLC group was (116±91)U/L, which was signifieandy lower than (169±96)U/L in RYC group (t=2.461, P<0.05). Three patients (2.3%) in MLC group and 9 (7.0%) in RYC group suffered from acute cholangitis after operation, with no statistical difference in the incidence between the 2 groups (P>0.05). Of the 12 patients with acute cholangids, 1 in MLC group and 7 in RYC group were hospitalized, with statistical difference between the 2 groups (P<0.05). Conclusions The incidence of acute cholangitis in patients who underwent MLC is comparable to that of RYC. However, the procedure of MLC is simpler than RYC, and patients have milder symptom and lesser frequency of reflux cholangitis onset after MLC.
