ObjectiveTo understand the current situation in the treatment of hepatic echinococcosis. MethodThe literatures about operation treatment, drug treatment, and the clinical pathway of hepatic echinococcosis were reviewed. ResultsCurrently, with the continuous development of surgical techniques and the application of minimally invasive surgery, the operative treatments of hepatic echinococcosis had made a great progress, it was still the preferred treatment for the disease. Liver transplantation was made as the final choice. The use of aspiration, sclerotherapy or interventional technique brought a hope for patients intolerant to laparotomy. Moreover, chemotherapy drugs, Chinese herbal medicine, and drug combinations also achieved a very good effect in the treatment of hepatic echinococcosis. The clinical pathway provided a good direction for the treatment of hepatic echinococcosis. ConclusionFor the treatment of hepatic echinococcosis various, we should choice a reasonable treatment according to the specific circumstances of patients, to achieve the best therapeutic effect with minimal trauma.
ObjectiveTo evaluate and discuss the various surgical methods for hepatic echinococcosis. MethodsFour hundred and two patients with hepatic echinococcosis were treated in West China Hospital of Sichuan University from 2009 to 2014 and 271 of them were undergone surgical treatment. The cystic echinococcosis was in 195 patients, including 80 cases performed classic endocystectomy or subtotal cystectomy, 109 performed total cystectomy or hepatectomy, 6 cases performed palliative surgery. The alveolar echinococcosis was in 76 patients, including 7 cases performed palliative surgery, 54 cases performed hepatectomy, 12 cases performed liver allotransplantation, and 3 cases performed liver autotransplantation. Results①The draining time, the rate of postoperative complications, and the recurrence was (18.6±2.7) d, 21.2% (17/80), and 15.0%(12/80) respectively in the cases of cystic echinococcosis underwent classic endocystectomy or subtotal cystectomy, which were significantly higher than those cases of cystic echinococcosis underwent total cystectomy or hepatectomy〔(5.4±0.6) d, 7.3% (8/109), and 0.9% (1/109), respectively, P < 0.05〕.②The draining time and the recurrence was (5.9±0.7) d and 1.8% (1/54) respectively in the cases of alveolar echinococcosis underwent hepatectomy, which were significantly lower than those in the cases of alveolar echinococcosis took palliative surgery〔(9.7±1.4) d and 57.1% (4/7), respectively, P < 0.01〕. The 12 patients underwent liver transplantation were complete rehabilitation, while the rest 3 were death. Conclusions①Total cystectomy or hepatectomy should be the first choice for cystic echinococcosis; Palliative treatment could improve the symptoms of unresectable patients with cystic echinococcosis.②Hepatectomy should be the first choice for alveolar echinococcosis, palliative surgery could only be used to alleviate symptoms and physical signs, delay the progression of this disease.③Liver transplantation might be an alternative for advanced hepatic echinococcosis.
ObjectiveTo explore the safety and efficacy of preoperative liver regeneration and then two-stage liver resection for advanced hepatic alveolar echinococcosis (HAE) patients pre-evaluating insufficient future liver remnant (FLR) after resection. MethodThe clinical data of the advanced HAE patients who were expected to have insufficient FLR after liver resection and underwent two-step liver resection in the Sichuan Provincial People’s Hospital from December 2016 to December 2022 were retrospectively collected and summarized. ResultsA total of 11 patients with advanced HAE pathologically confirmed were collected. Among them, 2 cases underwent portal vein embolization (PVE), 2 cases underwent liver vein deprivation (LVD), and 7 cases underwent associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) to promote residual liver regeneration in the first stage. The FLR/standard liver volume (SLV) exceeded the surgical requirement standard of 40%. Then the ex-vivo liver resection and autotransplantation, or directly radical liver resection was performed in the second stage. Only one patient underwent surgery to remove packed gauze on day 3 postoperatively due to massive intraoperative bleeding (approximately 4 000 mL). The median (P25, P75) follow-up time after surgery was 36 (15, 75) months, only one case was found to relapse at the third year after surgery and underwent surgical resection again, and the rest patients had no recurrence, long-term complications, or death. ConclusionsBased on the results from these cases, applying PVE, LVD, or ALPPS in the patients with advanced HAE who were expected to have insufficient FLR after resection aids to residual liver regeneration, creating conditions for the second stage radical resection. The second stage treatment including ex-vivo liver resection and autotransplantation or directly radical liver resection could achieve good results and is feasible and safe, which brings a hope of survival for the advanced HAE patients who could not previously undergo curative resection. However, this treatment strategy still incurs high costs and requires further optimization in the future.
ObjectiveTo evaluate roles and advantages of magnetic resonance imaging (MRI) and compute.tomography (CT) in preoperative assessment for hepatic alveolar echinococcosis. MethodMRI and CT scan imaging data of 60 patients with hepatic alveolar echinococcosis underwent radical surgery were retrospectively analyzed. ResultsMRI scanning could accurately identify the peripheral zone and marginal zone of hepatic alveolar echinococcosis lesions, and CT could not accurately show the above structures. In assessment of anatomic relation between vascular and lesions, MRI findings of 52 cases were in full compliance with corresponding intraoperative findings, and 8 cases were partial compliant. However, CT findings of 35 cases were in full compliance with corresponding intraoperative findings, 13 cases were partial compliant, and 12 cases were not compliant at all. In assessment of anatomic relation between biliary and lesions, MRCP could clearly show the bile duct, bile duct stenosis location and degree; CT scanning could only show widened bile duct, but could not accurately judge bile duct dilatation. ConclusionsMRI exerts some obvious advantages in preoperative evaluation of hepatic alveolar echinococcosis, and could accurately find relation between lesions and vascular or biliary system. MRI should be used as routine examination for patients with hepatic alveolar echinococcosis.
ObjectiveTo investigate the clinical significances of intraoperative methylene blue diluent injection through the residual bile duct for bile leakage after hepatic hydatidosis surgery.MethodsThe patients with hepatic hydatidosis who received the surgical treatment in this hospital from December 2018 to November 2019 were randomly divided into a study group and control group. The patients in the study group received the treatment of anatomical or nonanatomical hepatic lobectomy. The first hepatic hilum was locked, then the methylene blue diluent was injected through the residual bile duct to find the bile leakage. The drainage tube was retained in the abdominal cavity after the surgery. The patients in the control group except the white gauze was used to compress the liver wound surface for 5 min to find the bile leakage, the other treatment process was the same as the study group. The operation time, intraoperative blood loss, liver function on day 3 after the surgery (total bilirubin, alanine aminotransferase, albumin), detection rate of bile leakage during operation, postoperative complications (pulmonary infection, ascites, incision infection, bile leakage, residual cavity infection, and electrolyte disturbance), postoperative hospitalization time, and total hospitalization cost were compared between two groups.ResultsAccording to the inclusion and exclusion criteria, 67 patients were included in this study, including 32 in the study group and 35 in the control group. There were no significant differences in the baseline data such as the age, gender, preoperative complications, preoperative liver function (total bilirubin, alanine aminotransferase, albumin), and liver hydatid classification between the two groups (P>0.05). The operations were successful in the 67 patients, no perioperative death occurred. The detection rate of bile leakage during operation in the study group was higher than that in the control group (53.1% versus 17.1%, P<0.05). The postoperative hospitalization time was shorter and the total hospitalization cost was lower in the study group as compared with the control group (P<0.05). There were no significant differences in the operation time, intraoperative blood loss, liver function on day 3 after the surgery between the two groups (P>0.05). There was no case of the incision infection, bile leakage, and residual cavity infection in the study group, but there were 1, 5 and 4 cases in the control group, respectively. The incidences of incision infection and bile leakage had statistical significances between the two groups (P<0.05), and there was no significant differences in the incidences of other complications between the two groups (P>0.05).ConclusionsDetection rate of bile leakage during operation is high by intraoperative methylene blue diluent injection through the residual bile duct for bile leakage after hepatic hydatidosis surgery. It could reduce bile leakage, shorten postoperative hospitalization time, and reduce total hospitalization cost.
ObjectiveTo explore the clinical application of in vivo hepatectomy with preservation of retrohepatic inferior vena cava (IVC) for hepatic alveolar echinococcosis (HAE) with the invasion of IVC. MethodsThe clinicopathologic data of a complicated HAE patient with large lesion (maximum cross-section 12.6 cm×9.6 cm), infiltrative growth, unclear boundary with surrounding tissues, and invasions of diaphragm and IVC (invasion length up to 4.6 cm) admitted to the Department of Liver Surgery in the West China Hospital of Sichuan University in December 2021 was retrospectively collected. The three-dimensional reconstruction of the liver model was performed by Mimics Medical 21.0 software before operation. The invading IVC of the right liver lesion was measured and the resection was simulated. During the operation, the HAE lesion and the affected IVC were gradually separated from IVC by the hemostatic forceps, and the residual lesions were gradually removed. ResultsIn this patient, the HAE lesion of right liver was resected, the IVC was entirely preserved, and the resection of liver was consistent with the preoperative three-dimensional reconstruction plan. The operation time was 275 min, the bleeding was approximately 500 mL. On the first day after the operation, the alanine aminotransferase and aspartate aminotransferase were increased, no obvious abnormalities were observed in the plasma albumin and bilirubin, the patient recovered and was discharged on the seventh day after the operation. No complications occurred after the operation, and no recurrence or metastasis of HAE was observed during follow-up period. ConclusionsHepatectomy with preservation of retrohepatic IVC for HAE with invasion of IVC is safe and effective. Taking albendazole regularly after surgery will help maintain disease-free survival.
ObjectiveTo comprehend the current diagnosis status and new progress of hepatic echinococcosis (HE). MethodThe literature from domestic and foreign researchers relevant diagnosis of HE in recent years was searched and summarized. ResultsThe HE was widely distributed worldwide, with extremely high mortality and disability rates, posing a serious threat to local economic development and public health. At present, in addition to the traditional and widely recognized diagnostic methods based on epidemiological histories, clinical manifestations, routine imaging, and experimental examinations, many innovative technologies based on these traditional diagnostic methods had emerged in the field of HE diagnosis, such as diagnostic prediction models constructed based on ultrasound and other imaging data, artificial intelligence, three-dimensional visual reconstruction, and circulating free DNA testing, which significantly improved the diagnosis rate of the HE. ConclusionsIn recent years, with the continuous improvement of medical level, the in-depth and perfect exploration of HE has made remarkable progress, which not only provides a new possibility for the early diagnosis of the HE, but also provides an important basis for research in related fields and the formulation of prevention and control measures. Therefore, the further promotion and application of these new techniques will aid to promote the diagnosis progress of HE and reduce its impact on population health.
ObjectiveTo detect expressions of interleukin-17 (IL-17) and interleukin-27 (IL-27) proteins in liver tissue of hepatic alveolar echinococcosis. MethodsThe edge liver tissues (from the lesion edge 0.5 cm) and the normal liver tissues (from the lesion edge 5 cm) of 20 patients with hepatic alveolar echinococcosis in the Affiliated Hospital of Qinghai University were collected and stored at-80℃ freezer. The immunohistochemical method was used to detect the expressions of IL-17 and IL-27 proteins in these two tissues. ResultThe positive rates of IL-17 and IL-27 protein expressions in the edge liver tissues were significantly higher than those in the normal liver tissues[IL-17:80.0% (16/20) versus 10.0% (2/20), χ2=12.36, P < 0.01; IL-27:85.0% (17/20) versus 20.0% (4/20), χ2=12.36, P < 0.01]. ConclusionHigh expressions of IL-17 and IL-27 protein in edge liver tissue might participate in progress of hepatic alveolar echinococcosis.
ObjectiveTo discuss various surgical methods for hepatic alveolar echinococcosis. MethodsThe clinical data of 98 patients with hepatic alveolar echinococcosis treated in West China Hospital of Sichuan University from 2004 to 2015 were analyzed retrospectively. Palliative surgeries were performed in 9 cases, radical hepatectomies were performed in 69 cases, liver transplantations were performed in 20 cases, in which 12 cases were performed by liver allotransplantation, and 8 cases were performed by liver autotransplantation. ResultsThere was no death case during perioperative period. The rate of postoperative complications of the radical hepatectomy (11.6%, 8/69) was significantly lower than that of the palliative surgery (44.4%, 4/9), which had statistically significant difference (P<0.05). The followup time was from 4 months to 6 years, the average time was 36 months. The postoperative recurrence rate in the radical hepatectomy (1.4%, 1/69) was significantly lower than that in the palliative surgery (55.6%, 5/9), which had statistically significant difference (P<0.05). During follow-up period, the mortality of the palliative surgery (33.33%, 3/9) was also significantly higher than that of the radical hepatectomy (0, 0/69), which had statistically significant difference (P<0.05). Four patients underwent liver transplantation were death within 3 months (20.0%). ConclusionsRadical hepatectomy should be the first choice for alveolar echinococcosis. In this research, although the rates of postoperative complications and recurrence in palliative surgery are higher than those in radical hepatectomy, palliative surgery, for the patients who had lose the opportunity to perform radical hepatectomy, could be used to alleviate symptoms and physical signs, improve quality of life, delay progression of this disease. Although risk of liver transplantation is high, this might be an alternative for advanced hepatic alveolar echinococcosis.
ObjectiveTo investigate the clinical effect of transversus abdominis plane (TAP) block as part of multimodal analgesia in enhanced recovery after surgery (ERAS) program for patients with hepatic hydatidosis. MethodsThis study was a randomized controlled trial (The registration number was ChiCTR2100053689). According to the established inclusion and exclusion criteria, the patients diagnosed with hepatic hydatidosis treated in the People’s Hospital of Aba Tibetan and Qiang Autonomous Prefecture from October 2019 to August 2021 were prospectively included. The odd and even by obverse and reverse of coin was adopted to assign into the study group and the control group, respectively. The patients in the study group were treated with ERAS + TAP block + patient controlled intravenous analgesia (PCIA) + tramadol and the patients in the control group were treated with ERAS + PCIA + tramadol. The intraoperative and postoperative statuses of the two groups were compared. ResultsA total of 64 patients were enrolled in this study, including 32 patients in the study group and 32 patients in the control group. There were no statistical differences in the baseline data such as the age, gender, preoperative complications, preoperative liver function, and liver hydatid type between the two groups (P>0.05). The operations of 64 patients were performed successfully, and there was no perioperative death. There were no statistical differences in the operation time, intraoperative bleeding, and operation mode between the two groups (P>0.05). Compared with the control group, the points of visual analogue scale of postoperative pain on day 1 and 2 were lower (P<0.05), the dosage of tramadol within 2 d after operation and hospitalization expenses were less (P<0.05), and the getting out of bed time, eating liquid diet time, postoperative exhaust time, and total hospital stay were shorter (P<0.05) in the study group. The total complication rate of the study group was lower than that of the control group [28.1% (9/32) vs. 78.1% (25/32), χ2=16.063, P<0.001]. The comprehensive complication index was positively correlated with the total hospital stay (r=0.941, P<0.001) and hospitalization expenses (r=0.958, P<0.001). ConclusionPreliminary results of this study suggest that multimodal analgesia included TAP block is effective in ERAS, and could shorten hospital stay and reduce hospitalization expenses.
