Objective To summarize the diagnosis and treatment for primary hepatic neuroendocrine carcinoma. Methods The clinicopathologic data of three patients with primary hepatic neuroendocrine carcinoma from June 2010 to June 2011 in this hospital were analyzed retrospectively. Results Three cases were difficult to diagnose primary hepatic neuroendocrine carcinoma before operation. All the treatments were resection. Three patients were diagnosed as neuroendocrine carcinoma by pathology and immunohistochemistry after operation. All of them were treated by octreo-tide after operation and discharged from hospital successfully. There was no relapse one year later. At present， 3 patients were still continue to follow-up. Conclusions The diagnosis of primary hepatic neuroendocrine carcinoma is very difficult before operation， the assessment of treatment and curative effect is exploring.
To study the changes in diagnosis and treatment of pediatric choledochal cyst in the past 10 years, a retrospective analysis was made in 79 children with choledochal cyst, who were admitted into our hospital from 1982 to 1998. Results show that in the past years, the clinical manifestation of choledochal cyst in children have become less obvious for earlier consultation. B-mode ultrasounscanning should be the first choice since it aids in the diagnosis of choledochal cyst as well as its related and complicated diseases. Choledochectomy is the only radical treatment for choledochal cyst in children.
Prevention and treatment of traumatic neuroma by implanting the proximal neural stump into the muscle were studied. Sixteen SD rats were used for the experimental study. The proximal stump of the left sciatic nerve was implanted into the nearby muscle as the experiment side, whereas the proximal stump of the right sciatic nerve was left untreated as the control side. The results were assessed with histological and electrophysiological methods. The experiment demonstrated that neuroma was formed in the control side one month postoperatively, whereas in the experimental side the nerve fibers were dispersed among the muscle fibers and no definite neuroma was formed. Implantation of neural stump into muscle could prevent and treat traumatic neuroma.
Objective To report the experiences using orthotopic heart transplantation （HTX） to treat a patient with primary cardiac pheochromocytoma （PCT）. Methods On June 2, 2005, a 48-year-old woman received orthotopic HTX because she suffered from cardiac PCT which can not be resected. The procedure for the recipient was uneventful. The aortic crossclamp time was 95 min, assist circulation time 64 min. Results Twenty days after the operation, the patient was discharged without any events, and serum norepinepherine dropped to 1. 339 ng/ml, and urinary norepinepherine 108μg/24h. Conclusion Orthotopic HTX is an effective treatment for cardiac PCT when it cannot be resected.
ObjectiveTo study the clinical manifestations, pathologic characteristics, imaging features, diagnosis and treatment of adenomas of extrahepatic bile duct.MethodsTwo cases of adenomas of extrahepatic bile duct in our hospital and 14 cases reported in the literatures were analyzed retrospectively.ResultsThe patients’(male 5, female 11) mean age was 58.4 years (range 21-85). The main manifestations included jaundice (n=11), abdominal pain (n=8),fever (n=6),dyspepsia (n=4),body weight loss (n=3) and claycolored stool (n=1). The locations of tumors were in the left hepatic duct (n=1), right hepatic duct (n=3), hepatic common bile duct(n=3）,the junction of cystic duct and common bile duct (n=1），distal common bile duct (n=8). The pathologic types were tubular adenomas (n=5), papillary (villous) adenomas (n=10),and mucous adenoma (n=1). All the patients underwent surgical therapy. The tumors were identified by postoperative histopathologic examination.ConclusionIt is difficult to correctly diagnose adenomas of extrahepatic bile duct before operation, because the clinical manifestations are usually atypical. The definite diagnosis should depend on histopathologic examination. It is the key to completely resect the tumors. Postoperative followup should be done on regular basis.
ObjectiveTo investigate the anticoagulant drug treatment decision for patients with renal contusion and acute pulmonary embolism, and to enhance the level of treatment for this disease. MethodsA retrospective analysis of the clinical data of a patient with renal contusion and acute pulmonary embolism treated at the West China Hospital of Sichuan University, along with a relevant literature review. Databases including PubMed, Ovid Medline, Embase, VIP, Wanfang and Chinese National Knowledge infrastructure were searched using the keywords as “Pulmonary embolism” AND “Hemorrhage”from January 1983 to December 2023. ResultThe patient was a 21-year-old male who presented with right kidney contusion for 5 days and dyspnea for 1 day. The abdominal CT scan revealed a ruptured right kidney accompanied by hemorrhage and hematoma in the surrounding tissue. Abdomen ultrasound: a low echogenic area measuring approximately 10.6 cm×2.8 cm is noted around the right kidney. The CT pulmonary angiography (CTPA) demonstrated filling defects at the bifurcation of the pulmonary trunk, as well as within the upper and lower lobes of both lungs and their respective branches. The blood gas analysis of patient indicated (face mask oxygen therapy at 10 L/min, oxygenation index of 120): pH 7.456, PCO2 24.9 mm Hg, PO2 73.2 mm Hg. His myocardial markers were Myoglobin: 79.21 ng/ml, Troponin T: 58.7 ng/L, BNP: 2062 ng/L. The patient was diagnosed with renal contusion and pulmonary embolism, and was treated with subcutaneous heparin（initial dose is given as an 80 IU/kg intravenous bolus, followed by a continuous infusion of 12-18 IU/kg/h） and low-molecular-weight heparin at a dose of 0.8 ml every 12 hours one after another for anticoagulation, along with symptomatic treatment. Following the intervention, the patient's respiratory distress showed significant improvement, and subsequent arterial blood gas analysis indicated enhanced oxygenation. Then, the anticoagulant medication was adjusted to oral rivaroxaban anticoagulation for 6 months, follow-up CTPA scan revealed complete resolution of the pulmonary embolism and the abdominal CT scan indicated a reduction in the extent of patchy low-density shadows surrounding the right kidney, leading to the discontinuation of anticoagulation therapy. After searching the above-mentioned databases, total of 26 articles were identified that reported on 30 patients diagnosed with high-risk bleeding and acute pulmonary embolism; among these, 3 patients succumbed while 27 exhibited clinical improvement. ConclusionsPatients with renal contusion and acute pulmonary embolism can be safely and effectively treated with low-dose heparin anticoagulation under close monitoring. High-risk bleeding patients with acute pulmonary embolism present a significant challenge in clinical practice. After weighing the risks of bleeding disorders and the adverse outcomes of pulmonary embolism, it is necessary to find the optimal balance between anticoagulation and bleeding. Consequently, the formulation of personalized treatment strategies in accordance with established guidelines can enhance patient outcomes.

Cmplications occurred in 14 patients with 2 patients died of complications.Conclusion Regiono-perfusional chemotherapy of pancreatic adenocarcinoma is effective, but the complications can not be neglected.
Objective
To investigate the therapeutic effects of retinal angiomatosis in different clinical stages. To discuss the indication of vitrectomy for retinal hemangioblastoma.
Methods
The clinical data of 22 cases (33 eyes) were retrospectively analyzed. The retinal hemangiomas were divided into 5 stages according to their degrees of development from simple angioma without vessel dilation to feeder vessel dilation and intra-retinal exudates, local retinal detachment, massive retinal detachment and co mplication occurrence in proper order. The methods of treatment were laser photo coagulation, trans－scleral cryotherapy and vitrectomy. 13 eyes were treated with laser photocoagulation, 5 eyes with cryotherapy combined with laser and 11 eye s with vitrectomy. Tumor resection and silicone oil tamponade was performed in 3 eyes during vitrectomy. The patients were followed up for 46 months on average. Visual acuity (VA), the condition of the hemangioma and retina was compared pre- and post-operation respectively.
Results
In all 13 eyes treated with laser photocoagulation the hemangiomas regressed and the retina remained attached. VA improved in 2 eyes, and remained unchanged in 11 eyes. Cryother apy combined with laser photocoagulation was performed on 5 eyes. In this group, 4 eyesprime; hemangiomas regressed and no new hemangiomas occurred, proliferative vitreous retinopathy and vitreous hemorrhage was observed in 1 eye which vitrecto my was performed later. VA improved in 2 eyes, unchanged in 2 eyes and decreased in 1 eye. In the 11 eyes treated with vitreoretinal surgery, new hemangiomas wa s found in 1 eye, exudative retinal detachment was caused by hemangiomas in 2 eyes, proliferative vitreous retinopathy was observed in 2 eyes, and the retina re mained attached in 8 eyes. VA improved in 3 eyes, unimproved in 3 eyes, and decreased in 5 eyes. In the 3 eyes with surgical resection of retinal hemangioma during vitrectomy, 2 eyesprime; retina remained attached, 1 eye had exu dative retinal detachment and no new hemangiomas occurred. VA improved in 2 eyes and decreased in 1 eye.
Conclusions
Laser photocoagulation or combined with cryotherapy is effective in treating the hemangiomas in early stage. Vitrectomy is advisable for late stage of retinal angiomatosis, especially with vitreous hemorrhage, epiretinal membrane, proliferation and large scale of r etinal detachment. Surgical resection of isolated large retinal hemangioblastoma may be useful for selected patients.
