A review of the literature revealed only four such cases. To the best of our knowledge, this is the first report of spontaneous rupture of splenic hamartoma associated with liver cirrhosis and portal hypertension. A 53-year-old woman, who was followed up for aortic dissection and hepatitis C virus （HCV）-related liver cirrhosis, was referred with sudden left chest and shoulder pain. An abdominal ultrasound showed intraabdominal bleeding, and computed tomography indicated rupture of a splenic tumor. Emergent splenectomy was carried out. The postoperative course was uneventful, and the patient was discharged on the 13th postoperative day. Pathology revealed the tumor to be a ruptured splenic hamartoma. The non-tumorous splenic parenchyma revealed congestive changes. We consider that the presence of liver cirrhosis and portal hypertension are risk factors for spontaneous rupture of the splenic hamartoma.展开更多

METHODS:Between 2001 and 2009,a total of 98 patients with colorectal adenocarcinoma and non-resectable metastases were diagnosed and treated with the new systemic agent chemotherapy regimen FOLFOX. Primary site resection was carried out in 38 patients, creation of a colostomy or bypass without resection was carried out in 36 patients,and 23 were not operated on because of advanced disease.The survival times of patients in different groups were analyzed. RESULTS:There were no differences between the patients regarding their general condition,concurrent disease,or tumor stage according to AJCC classification.The median survivals of the three groups were 30.6,20.8,and 12.7 mo(log-rank P value<0.05),respectively.The postoperative complication rate was higher in the primary site resection group than in the palliative surgery group. CONCLUSION:The results indicate that there are benefits from primary site resection for incurable metastatic colorectal cancer with systemic chemotherapy.展开更多

Contrastenhanced computed tomography showed a blind loop of the bowel extending to near the uterus and a fibrotic band connecting the mesentery to the top of the bowel,suggestive of Meckel's diverticulum(MD) and a mesodiverticular band(MDB). After intestinal decompression,elective laparoscopic surgery was carried out. Using three 5-mm ports,MD was dissected from the surrounding adhesion and MDB was divided intracorporeally. And subsequent Meckel's diverticulectomy was performed. The presence of heterotopic gastric mucosa was confirmed histologically. The patient had an uneventful postoperative course and was discharged 5 d after the operation. She has remained healthy and symptom-free during 4 years of follow-up. This was considered to be an unusual case of preoperatively diagnosed and laparoscopically treated small-bowel obstruction due to MD in a young adult woman.展开更多

Ultrasonography and abdominal contrast computed tomography revealed a hypervascular tumor of 1 cm in diameter in the pancreatic tail. With a diagnosis of insulinoma, we performed a distal pancreatectomy. The patient showed a good postoperative course without any complications. The patient's early morning fasting hypoglycemia disappeared. The respective levels of C-peptide and insulin dropped from 14.9 ng/mL and 4860 μIU/mL preoperatively to 5.3 ng/mL and 553 μIU/mL after surgery. A histopathological examination demonstrated that the tumor was a pancreatic neuroendocrine tumor, grade 1. Immunostaining was negative for insulin and positive for CD56, chromogranin A, synaptophysin and glucagon. These findings suggested that the tumor was clinically an insulinoma but histopathologically a glucagonoma. Among all insulinoma cases reported between 1985 and 2010, only 5 cases were associated with independent glucagonoma. In this report, we characterize and discuss this rare type of insulinoma by describing the case we experienced in detail.展开更多
