An integrated surgical training program for hepatic cystic echinococcosis in Xinjiang of China.

ABSTRACT: BACKGROUND:Human cystic echinococcosis (CE) is one of the commonest zoonoses, and it is endemic in many parts of the world including China. Complications and recurrences after the surgical treatment of hepatic CE (HCE) incur a large personal, healthcare, and societal burden. There has been some progress in HCE prevention, diagnosis, and treatment, but there is no "one size fits all" approach, and surgery still remains the cornerstone of treatment for some cyst stages and locations or in areas with little knowledge or access to other treatment modalities. In 2009 we designed and implemented a program to improve surgical outcomes from HCE in Xinjiang province, China. METHODOLOGY/PRINCIPAL FINDINGS:A multimodal HCE training program was implemented in eleven primary hospitals in Xinjiang province, China, which provided education and training on HCE clinical knowledge and practice, the application of diagnostic and treatment options, and optimal surgery. The management of HCE cases was analyzed before and after program implementation. Contrast enhanced CT use, application of scoloicidal agents, removal of necrotic cyst wall remnants, appropriate perioperative drug use, and the use of optimal surgical approach increased after program implementation. Further, postoperative recurrences and residual cavity complications creased from 7.4% to 1.3% and 15.2% to 9.0% after program implementation, respectively. CONCLUSIONS/SIGNIFICANCE:Tis integrated surgical training program is useful for improving outcomes of patients with HCE and can be used in institutions in other endemic areas.

Project description:BackgroundIn patients with hepatic cystic echinococcosis (CE), treatment effectiveness, outcomes, complications, and recurrence rate are controversial. Endocystectomy is a conservative surgical approach that adequately removes cyst contents without loss of parenchyma. This conservative procedure has been modified in several ways to prevent complications and to improve surgical outcomes. This systematic review aimed to evaluate the intraoperative and postoperative complications of endocysectomy for hepatic CE as well as the hepatic CE recurrence rate following endocystectomy.MethodsA systematic search was made for all studies reporting endocystectomy to manage hepatic CE in PubMed, Web of Science, and Cochrane CENTRAL databases. Study quality was assessed using the methodological index for non-randomized studies (MINORS) criteria and the Cochrane revised tool to assess risk of bias in randomized trials (RoB2). The random-effects model was used for meta-analysis and the arscine-transformed proportions were used to determine complication-, mortality-, and recurrence rates. This study is registered with PROSPERO (number CRD42020181732).ResultsOf 3,930 retrieved articles, 54 studies reporting on 4,058 patients were included. Among studies reporting preoperative anthelmintic treatment (31 studies), albendazole was administered in all of them. Complications were reported in 19.4% (95% CI: 15.9-23.2; I2 = 84%; p-value <0.001) of the patients; biliary leakage (10.1%; 95% CI: 7.5-13.1; I2 = 81%; p-value <0.001) and wound infection (6.6%; 95% CI: 4.6-9; I2 = 27%; p-value = 0.17) were the most common complications. The post-endocystectomy mortality rate was 1.2% (95% CI: 0.8-1.8; I2 = 21%; p-value = 0.15) and the recurrence rate was 4.8% (95% CI: 3.1-6.8; I2 = 87%; p-value <0.001). Thirty-nine studies (88.7%) had a mean follow-up of more than one year after endocystectomy, and only 14 studies (31.8%) had a follow-up of more than five years.ConclusionEndocystectomy is a conservative and feasible surgical approach. Despite previous disencouraging experiences, our results suggest that endocystectomy is associated with low mortality and recurrence.

Project description:BackgroundWith the mature application of laparoscopy in hepatobiliary surgery, laparoscopic treatment of hepatic cystic echinococcosis (CE) has made certain progress. But, due to the inherent limitations of laparoscopy and the growth characteristics of cystic echinococcosis, distinguishing the boundary between cystic lesion and normal hepatic parenchyma is pivotal importance for successful surgery. Indocyanine green (ICG) fluorescence imaging technology can view the boundary of lesion and normal tissue during the treatment of hepatic cystic echinococcosis. Applied laparoscopy combined with ICG fluorescence imaging technique for hepatic cystic echinococcosis may be an effective surgical strategy.MethodsThe clinical data contained nine patients with hepatic cystic echinococcosis who underwent laparoscopic surgery with indocyanine green fluorescence imaging technique in authors' institution from December 2018 to December 2019 were retrospectively analyzed. Indocyanine green was administered intravenously three days prior to surgery. The fluorescence acquisition system for real-time imaging was used during the surgery and the patients were followed up after surgery.ResultsOf reported nine patients, six are male and the remaining three are female. The average age is (36.4 ± 7.6) years. For all subjects, surgical procedures were performed under laparoscopy with indocyanine green fluorescence system. This technique showed the clear boundary of the hepatic cyst with normal liver parenchyma. Total cystectomy in six patients, subtotal cystectomy in two patients and partial hepatectomy in one patient were performed respectively. The average operation time was 3.8 ± 0.9 h, blood loss 206.0 ± 120.7 ml. Neither blood transfusion nor post-operative complication was experienced. The average abdominal drainage time was 3.4 ± 0.9 days with hospital stay 5.7 ± 2.1 days. During the 6-12 months follow-up period, neither recurrence nor intraperitoneal implantation was found.ConclusionsApplied laparoscopy combined with ICG fluorescence imaging technique for hepatic cystic echinococcosis is safe and feasible. Enhanced boundary image can assist surgeons to complete radical resection and reduce complications.
