  • Research advances in multimodal surgical treatment of hepatic alveolar echinococcosis

    ObjectiveTo summarize the research status and new directions of surgical treatment of hepatic alveolar echinococcosis (HAE) in clinic, and to provide reference for further research in improving the rate of radical surgery.MethodThe recent literatures on the studies of HAE were reviewed.ResultsAlthough the biological behavior of HAE was similar to that of malignant tumor, the clinical symptoms appeared late as the intrahepatic lesions often grow slowly. At present, the treatment of this disease was mainly surgical operation, among which radical resection was the first choice. Drug therapy was also of great value in controlling disease progression and recurrence. In recent years, with the progress of surgical technology, the surgical method had gradually developed to the direction of multi-mode combination, especially for those cases that had not been able to perform conventional radical surgery before.ConclusionThe treatment concept of clinical multi-mode combination can benefit more patients, even achieve clinical radical resection, and improve the rate of radical resection.

  • Application of three-dimentional visualized reconstruction technology in resection of treating hepatic alveolar echinococcosis

    Objective To evaluate effects of three-dimensional (3D) visualized reconstruction technology on short-term benefits of different extent of resection in treating hepatic alveolar echinococcosis (HAE) as well as some disadvantages. Methods One hundred and fifty-two patients with HAE from January 2014 to December 2016 in the Department Liver Surgery, West China Hospital of Sichuan University were collected, there were 80 patients with ≥4 segments and 72 patients with ≤3 segments of liver resection among these patients, which were designed to 3D reconstruction group and non-3D reconstruction group according to the preference of patients. The imaging data, intraoperative and postoperative indicators were recorded and compared. Results The 3D visualized reconstructions were performed in the 79 patients with HAE, the average time of 3D visualized reconstruction was 19 min, of which 13 cases took more than 30 min and the longest reached 150 min. The preoperative predicted liver resection volume of the 79 patients underwent the 3D visualized reconstruction was (583.6±374.7) mL, the volume of intraoperative actual liver resection was (573.8±406.3) mL, the comparison of preoperative and intraoperative data indicated that both agreed reasonably well (P=0.640). Forty-one cases and 38 cases in the 80 patients with ≥4 segments and 72 patients with ≤3 segments of liverresection respectively were selected for the 3D visualized reconstruction. For the patients with ≥4 segments of liver resection, the operative time was shorter (P=0.021) and the blood loss was less (P=0.047) in the 3D reconstruction group as compared with the non-3D reconstruction group, the status of intraoperative blood transfusion had no significant difference between the 3D reconstruction group and the non-3D reconstruction group (P=0.766). For the patients with ≤3 segments of liver resection, the operative time, the blood loss, and the status of intraoperative blood transfusion had no significant differences between the 3D reconstruction group and the non-3D reconstruction group (P>0.05). For the patients with ≥4 segments or ≤3 segments of liver resection, the laboratory examination results within postoperative 3 d, complications within postoperative 90 d, and the postoperative hospitalization time had no significant differences between the 3D reconstruction group and the non-3D reconstruction group (P>0.05). Conclusion 3D visualized reconstruction technology contributes to patients with HAE ≥4 segments of liver resection, it could reduce intraoperative blood loss and shorten operation time, but it displays no remarkable benefits for ≤3 segments of liver resection.

  • Learning curve of radical hepatectomy in treating hepatic alveolar echinococcosis with vascular infiltration: A cumulative sum analysis

    ObjectivesTo evaluate the learning curve of radical hepatectomy combined with vascular and/or bile duct reconstruction (RHVBR) in the treatment of hepatic alveolar echinococcosis (HAE), and to explore the feasibility and safety of RHVBR. MethodsThe clinical data of 203 patients who received RHVBR treatment for HAE complicated with vascular invasion in West China Hospital from 2010 to 2018 were analyzed retrospectively. Cumulative sum (CUSUM) and risk-adjusted cumulative sum (RA-CUSUM) were used to analyze the learning curve of RHVBR, determine the learning stage, and compare the differences of intraoperative and postoperative outcome indexes in different learning stages. ResultsThe average operative time was (537.9±207.6) minutes, with an average blood loss amounted to (616.5±724.7) mL. Postoperative complications occurred in 65 cases, and the incidence of complications was 32.0%. Among them, 29 cases (14.3%) had serious complications. Three cases (1.5%) died within 90 days after operation. The results of RA-CUSUM analysis showed that 54 cases of surgery were the cut-off point of learning curve for serious postoperative complications. According to the results of CUSUM analysis, the whole queue was divided into the first stage (n=53) and the second stage (n=150) based on the completion of 53 operations. Compared with the first stage, the operative time and total postoperative hospital stay in the second stage were shortened, the incidence of serious complications was reduced, and the number of resected liver segments was increased. The differences were statistically significant (P<0.05). ConclusionIt is feasible and safe to treat HAE with RHVBR, and the incidence of serious complications is obviously reduced after 54 cases of operation.

  • Comparison of the value of bedside lung ultrasound and lung stretch index in guiding optimal positive end-expiratory pressure during lung recruitment in patients with acute respiratory distress syndrome

    Objective To investigate the guiding value of bedside lung ultrasound and lung stretch index for optimal positive end-expiratory pressure (PEEP) in lung recruitment of patients with acute respiratory distress syndrome (ARDS). Methods From February 2020 to October 2023, 90 patients with ARDS requiring invasive mechanical ventilation were selected from the Department of Critical Care Medicine, the Second Affiliated Hospital of Zhengzhou University. According to the setting method of PEEP after lung recruitment, they were randomly divided into an ultrasound group (45 cases) and a stretch group (45 cases). Both groups were treated with PEEP incremental method for lung recruitment, and the ultrasound group was treated with bedside ultrasound-guided method to set PEEP after lung recruitment. PEEP was set by lung stretch index method in the stretch group. The dynamic changes of oxygenation index (PaO2/FiO2), dynamic compliance (Cdyn), mean airway pressure and peak airway pressure were monitored before lung recruitment and 15 min, 1 h, 6 h and 24 h after lung recruitment. Heart rate, mean arterial pressure and central venous pressure were monitored before and 24 h after lung recruitment in the two groups. The optimal PEEP value and the corresponding volume at the end of recruitment were explored. The mechanical ventilation time, ICU hospitalization time, incidence of barotrauma, incidence of extrapulmonary organ failure, and 28-day mortality were recorded as well. Results After lung recruitment, the oxygenation index, Cdyn, mean airway pressure, and peak airway pressure in the ultrasound group were higher than those in the stretch group at 15 min, 1 h, 6 h, and 24 h after recruitment (all P<0.05). There was no significant difference in heart rate, mean arterial pressure or central venous pressure between the two groups at 24 h after lung recruitment (all P>0.05). After lung recruitment, the optimal PEEP value and the corresponding volume at the end of recruitment in the ultrasound group were higher than those in the distraction group (both P<0.05). The mechanical ventilation time and ICU stay in the ultrasound group were shorter than those in the stretch group (both P<0.05). There was no significant difference in the incidence of barotrauma, extrapulmonary organ failure rate or 28-day mortality between the two groups (all P>0.05). Conclusions Both bedside lung ultrasound-guided PEEP and lung stretch index-guided PEEP can improve oxygenation and respiratory compliance, and have no adverse effects on hemodynamics. Bedside lung ultrasound-guided PEEP can make the alveoli fully expand, which is more conducive to improving patients’ oxygenation and respiratory compliance, and the guiding value is higher than the lung stretch index.
