RESUMO

Leiomyosarcoma of an artery is very rare, and cases with hepatic metastasis are even rarer. We describe a case of a 70-year-old man who after follow up due to rectal cancer, presented with an intra-abdominal hypervascular mass and a hepatic mass. After surgical resection, it was diagnosed as a leiomyosarcoma of the right gastroepiploic artery with hepatic metastasis. Multiple metastases had recurred at the liver. He has survived more than 53 mo through multimodal treatments (three surgical resections, radiofrequency ablation, transarterial chemoembolization, chemotherapies, and targeted therapy). Multimodal treatments, including active surgical resection, may be helpful in the treatment of aggressive diseases such as arterial leiomyosarcoma with metastasis.

RESUMO

Renal cell carcinoma (RCC) is the most common type of kidney malignancy. The pancreas is an infrequent site of metastasis in relation to any type of malignancy. However, RCC is one of the tumor types that most frequently metastasize to the pancreas. In this study, we report our experiences with two patients who underwent pancreatic resection for metastatic RCC tumors; of these two patients, one patient had a tumor was a metachronous pancreas-only tumor, and the other patient's tumor was synchronous with hematogenous lung metastasis. Following left-side pancreatic resection, the patients were administered tyrosine kinase inhibitors.

RESUMO

PURPOSE: The reflux of pancreatic enzymes into the biliary tract is associated with chronic inflammation and increases cellular proliferation of the biliary epithelium, leading to biliary carcinoma. The aim of this study is to detect the incidence of occult pancreaticobiliary reflux (OPBR) in patients who underwent elective cholecystectomy. METHODS: Forty-seven patients with symptomatic gallstones who underwent cholecystectomy were recruited for this study. The gallbladder bile samples were obtained from the specimen of gallbladder and the amylase level was measured. The immunohistochemistry of p53, SMAD4 and Ki-67 were performed for the detection of metaplasia and dysplasia. RESULTS: Biliary amylase was higher than the serum amylase in 10 patients (group A, 15,402.66 ± 33,592.43 IU/L; group B, 13.06 ± 18.12 IU/L). The mean age was 67.2 years in group A and 51.2 in group B (P < 0.01). The ratio of male to female was 1:2.3 and 1:1.8 in group A and B, respectively (P = 0.297). Eight patients in group A and thirteen patients in group B had inflammation (P = 0.014). The positive results of the Ki-67 test were exhibited in five cases in each group (P = 0.024). CONCLUSION: Results from the study indicate that the age was older, degree of inflammation and positive rate of Ki-67 were higher when OPBR was suspected. In conclusion, the patients with OPBR would need long-term follow-up, because the OPBR can cause dysplasia and the reflux of pancreatic juice may be considered as a risk factor for extrahepatic bile duct carcinoma.

RESUMO

BACKGROUNDS/AIMS: The objective of this study was to evaluate the relationship between initial personal experiences with distal pancreatectomy and perioperative risk factors, outcomes, and management of pancreatic fistulas. METHODS: Between May, 2007 and May, 2010, a total of 28 patients who had undergone elective distal pancreatectomy were evaluated for this study. Perioperative factors and the occurrence of pancreatic fistula were analyzed on the basis of International Study Group of Pancreatic Fistula (ISGPF) criteria. RESULTS: There were sixteen cases of benign neoplasms and twelve cases of malignant tumors. The remnant pancreas was manually sutured with ligation of the pancreatic duct (n=14), auto-suture stapling along with manual sutures (n=12), or stapling alone (n=2). According to the ISGPF classification, morbidity and mortality associated with pancreatic fistulas was 42.9% (n=12) and 0%, respectively. These pancreatic fistulae were classified as grade A in 8 cases (28.6%), grade B in 3 cases (10.7%), and grade C in one case (3.6%). All patients with pancreatic fistula were treated conservatively. CONCLUSIONS: Perioperative factors do not affect the risk of pancreatic fistula. Adequate drainage is the most effective method for management of a pancreatic fistula after distal pancreatectomy.
