ABSTRACT
Objective To study the results of emergency treatment of ruptured hepatic cystic echinococcosis (HCE).Methods A standardized management protocol for hepatic echinococcosis was introduced by the First Hospital of Xinjiang Medical University in 2002.This study included 185 patients who received emergency treatment for ruptured HCE between 1994 and 2009.The patients were divided into group A (from 1994 to 2001) and group B (from 2002 to 2009).The clinical characteristics and surgical treatment results were compared retrospectively.Results In patients with ruptured HCE into the abdomen,classical endocystectomy (Group A1 ) resulted in significantly more postoperative complications in residual hepatic cavity,time of drainage,postoperative hospital stay,recurrence and peritoneal seeding than improved endocystectomy (Group B1 ) (P＜0.05).The operation time and blood loss were not significantly different between group A1 and B1 (P＞0.05).For patients with ruptured HCE into the biliary tree,classical endocystectomy (Group A2 ) resulted in significantly higher postoperative complications in residual hepatic cavity,time of drainage,postoperative hospital stay and recurrence than improved endocystectomy (B2) (P＜0.05).Operation time,blood loss and peritoneal seeding were not significantly different between group A2 and B2 (P ＞ 0.05). Only one patient (0.54％) died from allergic shock in this series of patients.Conclusions Improved endocystectomy was an efficacious surgical treatment for ruptured HCE and it is recommended for emergency surgery.
ABSTRACT
Objective To investigate the diagnosis and treatment of ruptured hepatic cystic echinococcosis (HCE).Methods The clinical data of 109 patients with HCE who were admitted to the First Affiliated Hospital of Xinjiang Medical University from January 1994 to December 2009 were retrospectively analyzed.The diagnosis was based on the results of serological examination,epidemiological history,clinical manifestation and imaging findings.Of the 108 patients who received surgical treatment,67 received classic endocystectomy(classic group)and 41 received improved endocystectomy(improved group).The operation time,operative blood loss,length of postoperative hospital stay,time of drainage,effusion and infection of residual cavity,biliary fistula,pleura]effusion,local recurrence,dissemination and implantation of HCE,and death of the 2 groups were compared.All data were analyzed using the t test and chi-square test.Results The diagnostic rates of ultrasound,computed tomography and magnetic resonance imaging were 93%(101/109),99%(70/71)and 7/7,respectively.The positive rate of serological examination was 100%(61/61).Of the 109 patients,1 died of anaphylactic shock.The operation time and operative blood loss were(3.2 ± 0.3)hours and(104.0 ± 11.5)ml in the classic group and(3.3 ±0.4)hours and(110.0 ±23.8)ml in the improved group,respectively.There were no significant differences in the operation time and operative blood loss between the 2 groups(t =-1.474,-1.758,P ＞0.05).The length of hospital stay and time of drainage were(15.3 ± 4.3)days and(28.0 ± 4.6)days in the classic group and(9.3 ± 1.2)days and(7.6 ± 0.8)days in the improved group,respectively.There were significant differences between the 2 groups in the length of hospital stay and time of drainage(t = 8.628,28.088,P ＜0.05).The incidence rates of effusion and infection of residual cavity,biliary leakage,local recurrence,dissemination and implantation of HCE of the classic group were significantly higher than those in the improved group(x2 =4.335,3.888,5.691,4.581,10.153,P ＜0.05).Twenty-one patients received reoperation because of HCE recurrence or severe complications.Conclusions Epidemiological history,clinical manifestation,imaging findings and serological examination are important for the diagnosis of ruptured HCE.Improved endocystectomy + peritoneal lavage with hypertonic saline + administration of anti-HCE drugs is the optimal treatment for ruptured HCE.
