Objective:To investigate the clinical efficacy of da Vinci Xi surgical system assisted laparoscopic exocytosis for hepatic echinococcosis.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 7 patients who underwent da Vinci Xi surgical system assisted laparoscopic exocytosis for hepatic echinococcosis in Xinjiang Uiger Municipal People′s Hospital from October 2019 to July 2021 were collected. There were 3 males and 4 females, aged (43±12)years. Observation indicators: (1) surgical situations; (2) complications; (3) follow-up. Mea-surement data with normal distribution were represented as Mean±SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) Surgical situations. All 7 patients underwent da Vinci Xi surgical system assisted laparoscopic exocytosis for hepatic echinococcosis successfully, without conversion to laparotomy and laparoscopic surgery. None of the 7 patients underwent intraoperative blood transfusion and the operation time, volume of intraoperative blood loss, time to postoperative first and flatus, time to postoperative initial liquid food intake, time to postoperative abdominal drainage tube removal, time to postoperative urethral catheter removal, duration of postoperative hospital stay of 7 patients was (225±45)minutes, 100(range, 50-200)mL, (1.9±0.7)days, (4.2±1.2)days, (7±4)days, (2.9±0.8)days, (7±4)days, respectively. (2) Complications. None of the 7 patients had postoperative complications such as bile leakage, abdominal hemorrhage, incision infection, hydatid cavity infection, secondary operation, intestinal obstruction, pulmonary infection and deep venous thrombosis of lower limbs. (3) Follow-up. All 7 patients were followed up for 7 (range, 3-12) months. None of the 7 patients had recurrence of hepatic echinococcosis or peritoneal implantation and incision implantation, and all patients survived during follow-up.Conclusion:da Vinci Xi surgical system assisted laparoscopic exocytosis for hepatic echinococcosis is safe and feasible.

Objective:To evaluate the specialty of the clinical features, treatment procedure, clinical outcome, and prognosis in the patients with "sandwich" atlantoaxial dislocation (AAD).Methods:From 2008 to 2018, 160 cases with "sandwich" AAD were retrospectively selected from the case series of AAD in Peking University Third Hospital. The case series had 80 males and 80 females. The mean age at the initial visit was 35.5±14.6 years (range, 5-77). The clinical courses, treatment methodology and prognosis were reviewed. And the surgical approach, posterior fixation segment and the recovery of neurological function were mainly summarized. The atlantodental interval (ADI), the distance by which the odontoid exceeded the Chamberlain line and the cervical-medullary angle were analyzed.Results:The most common symptoms included weakness or numbness of the limbs (67.5%, 108/160), unstable gait (30%, 48/160) and vertigo (20%, 32/160). Among all, 130 cases (81.3%, 130/160) had myelopathy, with the Japanese Orthopaedic Association (JOA) scores from 4 to 16 (mean JOA scores 13.5±2.5). Cranial neuropathy was involved in 20 cases (12.5%). Radiological findings showed brainstem and/or cervical-medullar in 130 cases (81.3%), syringomyelia in 37 cases (23.1%) and Chiari malformation in 30 cases (18.8%). Computed tomography angiography (CTA) was performed in 90 cases, which showed vertebral artery anomalies in 55 cases (61.0%) and excessive medialized internal carotid artery in 5 cases (5.6%). All cases had no spinal cord or vertebral artery injury. The surgery included posterior occipito-cervical fusion (reducible dislocation, 145 cases), and transoral release followed by posterior fusion (irreducible dislocation, 15 cases). Fifty-seven cases were treated using alternative fixation technique. The average follow-up time was 50.5±22.4 months (range, 24 to 120 months). All of 152 cases (95.0%) achieved solid atlantoaxial fusion; there was no obvious osseous fusion formation on postoperative images in 6 cases (3.8%), but no atlantoaxial instability was found on dynamic radiographs; screw loosening happened in 2 patients (1.2%). Nine patients (5.6%) suffered complications, including 4 cases with recurrent dislocation, 2 screw loosening, 2 cases with bulbar paralysis and 1 wound infection. The mean postoperative JOA was 15.1±1.8 (range, 5-17), and the mean neurological improvement rate was 42.9%±33.3% in the patients with myelopathy.Conclusion:"Sandwich" AAD, a subgroup of AAD, has unique clinical features: earlier onset age and more severe myelopathy. The incidence of bone and vascular malformation is higher. So alternative surgical plan and hybrid fixation should be prepared for this subgroup of AAD.

Objective:To investigate the association between hepatic echinococcus granulosus infection and necrosis with gene polymorphism of interleukin-10 (IL-10) and tumor necrosis factor-α (TNF-α), and to identify the related factors at the gene level.Methods:A total of 106 patients with hepatic echinococcosis who underwent surgical treatment in the department of hepatobiliary surgery, People′s Hospital of Xinjiang Uygur Autonomous Region from January 2018 to December 2020 were selected. Patients with necrosis caused by hepatic echinococcus granulosus infection were selected as the observation group, and patients without necrosis caused by hepatic echinococcus granulosus infection were selected as the control group, with 53 cases in each group. The serum levels of IL-10 and TNF-α were detected by enzyme-linked immunosorbent assay (ELISA). The polymorphisms of IL-10 (-592, -1082) and TNF-α (rsl800630) were detected by polymerase chain reaction (PCR). The levels of IL-10 and TNF-α and their gene polymorphisms were analyzed.Results:The levels of serum IL-10 and TNF-α in the observation group were significantly higher than those in the control group (all P<0.05); There was significant difference in genotype and allele frequency of IL-10 (-592, -1082) and TNF-α (rsl800630) (all P<0.05). The serum IL-10 level of CC genotype patients with IL-10 gene -592C/A locus in the observation group was higher than that of CA+ AA genotype patients, with statistically significant difference ( P<0.05). The serum IL-10 level in patients with TT genotype at -1082T>A of IL-10 gene in the observation group was higher than that in patients with TA+ AA genotype, with statistically significant difference ( P<0.05). The serum TNF-α level in patients with CC genotype at rsl800630C/A locus of TNF-α gene in the observation group was higher than that in patients with CA+ AA genotype, with statistically significant difference ( P<0.05). Conclusions:The changes of IL-10 (-592, -1082) and TNF-α (rsl800630) gene polymorphisms may be associated with hepatic echinococcus granulosus infection and necrosis.
