【Abstract】ObjectiveTo study the mechanism of spontaneous rupture of hepatocellular carcinoma (HCC). MethodsArticles have been reviewed to find out the theory of spontaneous rupture of HCC. ResultsResearchful results suggested that the injury of small arteries was usually followed in patients of spontaneous rupture of HCC. In this review, the immune complex, which composed of hepatitis B virus e antigen, complement C1q and immunoglobulins, was found deposited in the elastic membrane of arteries. Likely as a result of immune complex deposition, vascular injury occurs mainly in the small arteries where the deposition of immune complex was present. The small arteries in which immune complex deposited are readily injuried and cause hemorrhage and rupture of HCC during vascular load increase. ConclusionWe would conclude that immune complex deposition in vessel wall led to the small arteries injury may be the factor involved in the pathogenesis of spontaneous ruptured HCC.
ObjectiveTo analyse the effectiveness of unicompartmental knee arthroplasty (UKA) for the patients with spontaneous osteonecrosis of the knee (SONK). MethodsBetween January 2012 and December 2016, 31 patients with SONK was admitted and treated with medial UKA. All patients were examined by both plain radiography and magnetic resonance images. The patients were composed of 5 men and 26 women with an average age of 64.3 years (range, 48-79 years), and with 16 left joints and 15 right joints. The average disease duration was 14.7 months (range, 6-26 months). Preoperative visual analogue scale (VAS) was 6.00±1.15, Hospital for Special Surgery (HSS) score was 55.77±11.03, and knee range of motion (ROM) was (114.68±10.40)°. The imaging examinations showed that all the lesions were located in the medial compartment of the knee joint and there were 19 patients with Aglietti stage Ⅳ and 12 patients with Aglietti stage Ⅴ. Preoperative femorotibial angle (FTA) was (177.39±1.63)° and posterior tibial slope (PTS) was (84.05±1.39)°. ResultsAll the incisions healed by first intention. All patients were followed up 14-46 months (mean, 25 months). At last follow-up, VAS score was 2.06±0.72 and HSS score was 86.45±3.67, which both improved significantly when compared with preoperative scores (t=22.73, P=0.00; t=–14.72, P=0.00). ROM was (118.06±3.80)° with no significant difference when compared with preoperative ROM (t=–1.78, P=0.08). The X-ray films showed there was no severe adverse events, such as periprosthetic infection, aseptic loosening, bearing dislocation, and so on. At last follow- up, PTS was (85.30±1.19)° with significant difference compared with preoperative one (t=–4.07, P=0.00); while FTA was (177.51±1.98)° with no significant difference when compared with preoperative FTA (t=–0.38, P=0.71). ConclusionUKA may be an optional management for SONK with minimally invasive, bone-preserving, and rapid recovery.
ObjectiveTo investigate the effect and prognosis of emergency hepatectomy and second stage hepatectomy after transcatheter arterial chemoembolization (TACE) in spontaneous rupture and bleeding of resectable primary liver cancer.MethodsA total of 42 patients with spontaneous rupture and bleeding of resectable primary liver cancer in this hospital from January 2010 to January 2016 were retrospectively reviewed. Among them 24 cases had accepted the emergency hepatectomy in 24 h–48 h after admission (emergency hepatectomy group, n=24), 18 cases had accepted the second stage hepatectomy in 1 week–2 weeks after the TACE (second stage hepatectomy group, n=18), the intraoperative blood loss and intraoperative blood transfusion volume, perioperative mortality, postoperative incidence of hepatic insufficiency, recurrence rate and abdominal metastasis rate within 1 year after the operation, 1- and 3-year survival rates were compared between the emergency hepatectomy group and the second stage hepatectomy group.ResultsThere was no significant difference in the preoperative general data between these two groups (P>0.050). The intraoperative blood loss and transfusion volume of the emergency hepatectomy group were significantly more than those of the second stage hepatectomy group (P=0.028, P=0.017). There were no significant differences in the perioperative mortality (P=0.489), incidence of hepatic insufficiency (P=1.000), 1- and 3-year survival rates (P=0.650, P=0.463) and 1-year recurrence rate (P=0.601) between these two groups. No intraperitoneal implantation metastasis was found in these two groups.ConclusionBoth emergency hepatectomy and second stage hepatectomy after TACE are safe and effective in treatment of spontaneous rupture and bleeding of resectable primary liver cancer, appropriate treatment should be selected according to the specific conditions of patients.
ObjectiveTo analyze the occurrence of postoperative pulmonary complications (PPC) and the risk factors in patients with spontaneous pneumothorax who underwent micro single-port video-assisted thoracoscopic surgery (VATS).MethodsA total of 158 patients with spontaneous pneumothorax who underwent micro single-port VATS in our hospital from April 2017 to December 2019 were retrospectively included, including 99 males and 59 females, with an average age of 40.53±9.97 years. The patients were divided into a PPC group (n=21) and a non-PPC group (n=137) according to whether PPC occurred after the operation, and the risk factors for the occurrence of PPC were analyzed.ResultsAll 158 patients successfully completed the micro single-port VATS, and there was no intraoperative death. The postoperative chest tightness, chest pain, and dyspnea symptoms basically disappeared. During the postoperative period, there were 3 patients of pulmonary infection, 7 patients of atelectasis, 4 patients of pulmonary leak, 6 patients of pleural effusion, 1 patient of atelectasis and pleural effusion, and the incidence of PPC was 13.29% (21/158). Multivariate logistic regression analysis showed that lung disease [OR=32.404, 95%CI (2.717, 386.452), P=0.006], preoperative albumin level≤35 g/L [OR=14.912, 95%CI (1.719, 129.353), P=0.014], severe pleural adhesions [OR=26.023, 95%CI (3.294, 205.557), P=0.002], pain grade Ⅱ-Ⅲ 24 hours after the surgery [OR=64.024, 95%CI (3.606, 1 136.677), P=0.005] , age [OR=1.195, 95%CI (1.065, 1.342), P=0.002], intraoperative blood loss [OR=1.087, 95%CI (1.018, 1.162), P=0.013] were the risk factors for PPC after micro single-port VATS.ConclusionThere is a close relationship between PPC after micro single-port VATS and perioperative indexes in patients with spontaneous pneumothorax. Clinically, targeted prevention and treatment can be implemented according to the age, pulmonary disease, preoperative albumin level, intraoperative blood loss, degree of pleural adhesion and pain grading 24 hours after surgery.
Objective?To summarize our experience of surgical treatment of Boerhaave’s Syndrome. Methods We retrospectively analyzed clinical records of 14 patients with Boerhaave’s syndrome in West China Hospital between January 1998 and December 2011. There were 11 male patients and 3 female patients with a mean age of 55.2±14.4 years and mean time interval between onset and admission of 49.6±21.2 h. Primary repair was performed in 11 patients.Esophagectomy and reconstruction of digestive track was performed in 1 patient and intra-luminal stent implantation was applied in 1 patient. Intercostal catheter insertion was performed in 1 patient.?Results?Thirteen patients underwent surgical therapy, and their survival rate was 84.6% (11/13). Among the eleven patients who underwent primary repair, 8 patients (72.7%)were cured and 3 patients experienced postoperative leakage resulting 2 deaths. The other one patient was cured with in-hospital time of 22.3±7.0 d. Two patients underwent digestive track reconstruction and intra-luminal stent implantation respectively and all survived with in-hospital time 39.0±5.7 d. Another patient underwent bedside chest drainage and died 10 d after admission.?Conclusion?Aggressive surgical management is an effective way to treat Boerhaave’s syndrome, and primary repair can lead to ideal prognosis in delayed patients whose time interval between onset and admission is beyond 24 h. Digestive track reconstruction and intra-luminal stent implantation are alternative methods on condition that primary repair can not be accomplished.
