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.
Objective To investigate the diagnosis and treatment of the liver hydatidosis in nonpastureland. Methods Clinical features of 16 patients with liver hydatidosis were analyzed retrospectively. Results Only 8 of 16 patients possessed the clinical symptoms and 8 patients had had history of inhabitancy in epidemic area. Casoni test and indirect hemagglutination showed a sensitivity of 90% and the correct diagnostic rate of CT was higher than that of B-ultrasound examination. The main effective treatment of the liver hydatidosis was surgical, 15 out of 16 patients received surgical treatment. In this series, the curative effect was good without any death, allergic reaction and implantation. Conclusion The cystic lesion of liver should be considered as liver hydatidosis and Casoni test, indirect hemagglutination, together with CT and B-us examination can be used to comfirm the diagnosis though no clinical symptoms and history of inhabitancy in epidemic area presented. Surgical operation is the main effective treatment for liver hydatidosis.
Objective To summarize the research status of percutaneous ultrasound interventional therapy for the patients with hepatic echinococcosis, and to provide some experience and reference for the treatment of disease in clinical medical personnel. Method The relevant literature on percutaneous ultrasound intervention therapy for hepatic echinococcosis both domestically and internationally was summarized and analyzed. Results For the patients with hepatic cystic echinococcosis (HCE), ultrasound-guided percutaneous transhepatic drainage is safe and effective for the World Health Organization Informal Working Group classification CE1 and CE3a cysts. For the patients with hepatic alveolar chinococcosis (HAE), although radical resection is still the gold standard, ultrasound-guided microwave ablation had better postoperative recovery and less trauma for patients with lesion diameter ＜5 cm; Due to limited research on the efficacy and safety of ultrasound-guided radiofrequency ablation for patients with HAE, further exploration is needed; Ultrasound guided percutaneous cyst puncture drainage is used for external drainage of necrotic material in the cyst cavity, which can effectively control infection and remove necrotic tissue; percutaneous transhepatic cholangial drainage (PTCD) could effectively relieve biliary obstruction, improve liver function, and enhance the quality of life of patients with advanced HAE complicated with obstructive jaundice. Conclusions Ultrasound-guided percutaneous interventional techniques have their own advantages and disadvantages in treatment of hepatic echinococcosis. For patients with HCE, strict indications and contraindications should be followed when performing percutaneous ultrasound interventions. For patients with HAE, early-stage small lesions should be prioritized for microwave ablation, and patients in the middle and late stages with larger lesions or those with intra-cyst infection or jaundice should be treated with percutaneous cyst puncture drainage and PTCD to alleviate symptoms, following the second stage operation.
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 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 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 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.
ObjectiveTo evaluate the effect of dilute autotransfusion in liver resection for patients with hepatic hydatid disease. MethodThirty patients with hepatic hydatid disease met the inclusion criteria were included. The changes of intraoperative hemodynamics, internal environment, and each system functions at different time point were observed. Results①There were no significant differences among mean arterial pressure, central venous pressure, heart rate in all the patients at each time point (P > 0.05), while, the other indexes including the concentrations of hemoglobin (Hb), hematocrit (Hct) after blood collection were all greatly lower than those before blood collection (P < 0.05), Na+, K+, Cl-, pH, and base excess after blood collection were all greatly lower than those before blood collection (P < 0.05). But all the indexes above mentioned (except for ph and base excess) returned to normal.②Compared with these indicators before surgery, the blood concentrations of AST, ALT, cardiac troponin I, and creatinin were all greatly increased (P < 0.05), the blood concentrations of Hb, Hct, platelet were all decreased apparently after surgery 1 day (P < 0.05). The prothrombin time and activated partial thromboplastin time were all prolonged (P < 0.05). But after surgery one week, those indicators had rebounded to the normal range. ConclusionThe application of dilute autotransfusion in liver surgery for patients with hepatic hydatid disease is safe, feasible, and saving.
ObjectiveTo summarize clinical treatments of hepatic alveolar echinococcosis in recent years and provide a new basis for guiding clinical practice. MethodsThe relevant literatures about treating hepatic alveolar echinococcosis at home and abroad were reviewed. The clinical curative effect and advantages or disadvantages among various treatments were analyzed. ResultsThe radical surgery was still the primary treatment of hepatic alveolar echinococcosis, liver transplantation was more used in the treatment of the late hepatic alveolar echinococcosis. surgery combined with chemical therapy had an obvously clinical curative effect. ConclusionsWith a high incidence and poor prognosis of hepatic alveolar echinococcosis, it is difficult to cure. Radical surgery, liver transplantation, chemotherapy and radiation therapy have been used in clinical treatment of hepatic alveolar echinococcosis. It is essential to fully acknowledge indications of various treatments. At the same time, if occurrence and development of this disease could be further researched, it might bring us a new hope of curing hepatic alveolar echinococcosis.
