【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.
Objective To study the relationship of hepatitis B virus （HBV） to spontaneous rupture of hepatocellular carcinoma （HCC-SR） and its mechanism. Method The related literatures about theory of HCC-SR were consulted and reviewed. Results The injury of small arteries was usually followed in patients with HCC-SR， which was related to vascular autoimmune injury caused by the HBV infection. The small arteries in which immune complex deposited were readily injured， as a result HCC-SR happened while vascular load increased. Conclusion The HBV infection resulted in vascular autoimmune injury maybe a important factor in the pathogenesis of HCC-SR.
ObjectiveTo summarize the application and experience of repairing spontaneous Achilles tendon rupture by part-Kessler technique with suture anchor. MethodsBetween January 2011 and December 2013, 31 patients with spontaneous Achilles tendon rupture were treated by part-Kessler technique with suture anchor. Of 31 cases, 23 were male and 8 were female, aged 16-53 years (mean, 38 years). The left side was involved in 15 cases and the right side in 16 cases. The causes of injury included sudden heel pain and walking weakness during sports in 22 cases; no surefooted down-stairs, slip, and carrying heavy loads in 9 cases. The distance from broken site to the calcaneus adhension of Achilles tendon was 3-6 cm (mean, 4.2 cm). The time from injury to operation was 7 hours to 4 days (mean, 36.8 hours). ResultsAll incisions healed by first intention without nerve injury or adhering with skin. The patients were followed up 6-24 months (mean, 15 months). All patients could complete 25 times heel raising without difficulty at 6 months after operation. No Achilles tendon rupture occurred again during follow-up. At 6 months after operation, the range of motion of the ankle joint in dorsiflexion and plantar flexion showed no significant difference between normal and affected sides (t=0.648, P=0.525; t=0.524, P=0.605). The circumference of the affected leg was significantly smaller than that of normal leg at 6 months after operation (t=2.074, P=0.041), but no significant difference was found between affected and normal sides at 12 months after operation (t=0.905, P=0.426). The American Orthopedic Foot and Ankle Society (AOFAS) scores at 6, 12, 18, and 24 months after operation were significantly higher than preoperative score (P<0.05); the score at 6 months after operation was significantly lower than that at other time points (P<0.05), but no significant difference was shown between the other time points (P>0.05). ConclusionRepairing spontaneous Achilles tendon rupture by part-Kessler technique with suture anchor can supply strong strain and decrease the shear forces of suture. So part-Kessler technique with suture anchor is successful in repairing spontaneous Achilles tendon rupture.
ObjectiveTo investigate the effectiveness of modified extensor indicis proprius (EIP) tendon transfer for reconstruction of spontaneously ruptured extensor pollicis longus (EPL) tendon by comparing with the traditional EIP tendon transfer. MethodsBetween January 2009 and December 2011, 11 cases of spontaneously ruptured EPL tendon were treated by modified EIP tendon transfer to reconstruct extension function (modified group). On the base of traditional procedure, the proximal end of EPL tendon was sutured with EIP tendon and the distal end of EIP tendon was crossed round extensor pollicis brevis (EPB) tendon and sutured back with EPL tendon. A specific EI-EPL evaluation method (SEEM) was used to measure the EPL tendon function after transfer. The result was compared with that of the other 18 cases undergoing traditional operation (traditional group). There was no significant difference in gender, age, disease duration, and injury causes between 2 groups (P gt; 0.05). ResultsAll incisions healed by first intention. In traditional group, 5 cases were out of follow-up, and the other 24 cases were followed up 1 year and 6 months on average (range, 8 months-2 years and 6 months). At the last follow-up, according to the evaluation of SEEM, the thumb elevation and flexion deficits of modified group were significantly less than those of traditional group (P lt; 0.05). The independent elevation deficit of the index finger of modified group was similar to that of traditional group (P gt; 0.05). The effectiveness was excellent in 9 cases and good in 2 cases with an excellent and good rate of 100% in modified group, and was excellent in 5 cases, good in 6 cases, and fair in 2 cases with an excellent and good rate of 84.6%. The effectiveness of modified group was significantly better than that of traditional group (χ2=0.03, P=0.03). ConclusionReconstruction of EPL tendon function by modified EIP tendon transfer is effective and easy. It can increase strength of the transferred tendon and obtain satisfactory results, but the long-term effectiveness needs further follow-up.
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.
