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 evaluate the role of octreotide in the treatment of severe acute pancreatitis (SAP). Seventy-six patients were divided into two groups (octreotide group, n＝38, control group, n＝38). All patients were treated by the same conservative regime. The octreotide group received octreotide. Results: The abdominal symptoms and signs, WBC count, serum amylase level, and volume of ascites were more effective controlled, with fewer complications occurred in octreotide group. Conclusion: Octreotide has a beneficial effect on the treatment of SAP, but the mechanism will be further investigated.
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.
ObjectiveTo evaluate the efficacy and safety of half-dose verteporfin photodynamic therapy (PDT) for chronic central serous chorioretinopathy (CSC). Methods35 eyes (35 patients) with chronic (or recurrent) CSC treated with half-dose verteporfin PDT. Best-corrected visual acuity(BCVA), central macular thickness (CMT) were measured before and after treatment (1, 3 and 6 months). The mean BCVA was 0.28±0.22, mean CMT was(384.5±85.0)μm. The situation of subretinal fluids (SRF) absorption was observed. ResultsIn 35 eyes, SRF of 29 eyes (82.9%) completely absorbed and 6 eyes (17.1%) not completely absorbed after one month of treatment. SRF of all eyes (100.0%) completely absorbed after three months of treatment. After 6 months of treatment, SRF of 3 eyes (8.6%) were recurrence, which might be completely absorbed when a half-dose maintenance therapy PDT was used again. The mean BCVA significantly improved to 0.14±0.13 at 1 months, 0.05±0.11 at 3 months and 0.05±0.12 at 6 months after PDT (t=5.410, 7.830, 7.758; P < 0.05). The mean CMT decreased to (224.3±61.4) μm at 1 months, (199.6±32.7) μm at 3 months and (205.3±39.6) μm at 6 months after PDT (t=11.856, 11.781, 11.900; P < 0.05). The mean CMT of controlled 32 eyes after treatment was (198.5±33.9) μm, much lower than the fellow eyes(232.3±17.5) μm (t=-3.988, P < 0.05). ConclusionsHalf-dose verteporfin PDT was safe and effective in treating chronic CSC, but may cause thinning of CMT.
Objective To investigate development and perspectives of brain death donation and transplantation. Methods The related literatures about the research of brain dead donors were reviewed. Results Brain death effects hemodynamic stability， hormonal changes， neuroimmunologic effects，and unleashes a cascade of inflammatory events， which may affect quality of graft， graft survival， and patient outcome. Moreover， the exact mechanism linked to brain death is incompletely understood. Conclusions The pathological physiology changes of brain dead donors has important impact on graft outcomes. However， subsequent work remains to be done.
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 investigate the prophylaxes, diagnosis and treatment of pelvi-peritoneal hernia (PPH) after Miles operation for rectal carcinoma. Methods Three hundred and nine patients who underwent Miles operation from January 1986 to June 1999 were collected and analysed retrospectively, 11 of them were complicated with PPH. Results The morbidity of PPH after Miles operation was 3.6% (11/309). The main manifestations included abdominal distention to some extent (11 cases), pain (3 cases), vomiting (2 cases), gastric liquid more than 500 ml a day by gastric tube (3 cases), and non-exsufflation of the stoma of colostomy (11 cases). Two cases had pea green small intestinal liquid by perineal tube. The signs were slight abdominal tender (5 cases), active or excessive intestinal gurgling sound (7 cases), and diminished intestinal gurgling sound (4 cases). Abdominal plane films, showing the distant small intestinal obstruction, were taken in all 11 cases. Only 2 patients were correctly diagnosed before reoperation, and other patients were regarded as adhesive intestinal obstruction. The average observational time following appearance of the clinical manifestations after Miles operation was 7.4 days. All patients were diagnosed by laparotomy, 3 of them underwent adhesion lysis and reposition, and 8 patients partial ileum resection and anastomosis. The content of the hernias was ileum. The morbidity after reoperation was 27.3% (3 cases), and the complication was wound infection. All 11 patients were cured and left hospital. Conclusion The PPH after Miles operation is often lack of typical clinical manifestations. The early diagnosis and laparotomy in time is key to management. It is important to prevent the complication.
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.
