Chronic focal pancreatitis and pancreatic carcinoma can be distinguished from each other by analysis of in vivo H-MR spectra, and in vivo H-MRS can be a useful method for making a differential diagnosis between chronic focal pancreatitis and pancreatic carcinoma.
Backgrounds/AimsFor patients with acute cholecystitis, conversion from laparoscopic cholecystectomy to open surgery is not uncommon due to possibilities of serious hemorrhage at the liver bed and bile duct injury. Recent studies reported successful laparoscopic subtotal cholecystectomy for acute cholecystitis. The purpose of this study was to determine the efficacy and feasibility of such an operation based on the experience of surgeons at our facility.MethodsIn this study, we enrolled 144 patients who had received either laparoscopic subtotal cholecystectomy (LSC), laparoscopic cholecystectomy (LC), or open cholecystectomy (OC) for acute cholecystitis from January 2004 to December 2009 at the Department of Surgery of our hospital. Their symptoms, signs, operative findings, pathologic results and postoperative results were compared and analyzed.ResultsThere were 26 patients in the LSC group 80 in the LC group and 38 in the OC group. There were no differences in mean age, sex, and symptoms of acute cholecystitis. The LSC group showed higher CRP levels (p<0.001) and a higher grade according to the Tokyo criteria (p=0.001). The mean operative time was 115.6 minutes and mean blood loss was 158.9 ml without intra-operative or postoperative transfusion. There weren't any bile duct injuries during the operation. No group suffered bile leakage. Drains were removed 3.3 days after the operation in the LC group, the shortest time compared to the other groups (p<0.001). LC and LSC groups demonstrated shorter postoperative hospital days and time to diet resumption than the OC group (p<0.001).ConclusionsLSC appears to be a safe and effective treatment in cases of severe acute cholecystitis that require consideration of conversion to open surgery.
Gallbladder paraganglioma is a very rare tumor and so far only a few cases have been reported. Most of these were asymptomatic and were found incidentally during operation. Recently, we experienced a gallbladder paraganglioma that gave rise to hemorrhage, which in turn caused acute cholecystitis. Our case involved a 45 year-old female patient complaining of an intermittent right upper abdominal pain. After a preoperative evaluation, cholecystectomy and lymphadenectomy were performed under the impression of gallbladder cancer with acute cholecystitis. Postoperative pathologic examination revealed a hemorrhagic gallbladder paraganglioma accompanied by acute cholecystitis. Immunohistochemical staining of the chief cells for neuron specific enolase, chromogranin and synaptophysin were positive. Sustentacular cells also stained positively for S100 protein.
Non-functioning pancreatic neuroendocrine tumors (NF-PNETs) are rare tumors that account for 2% of all pancreatic malignancy. About 60% of NF-PNETs present distant metastases and usually hepatic metastases. However, cutaneous metastases are very rare. Herein, we report our experience with a 60-year-old male who visited our outpatient clinic with a mass on his left hip. An abdominal computerized tomography scan demonstrated not only a left hip mass and an enlarged left inguinal lymph node, but also a huge heterogeneous enhancing mass on the pancreas. Initially, we removed the metastatic lesions, which was a small cell neuroendocrine carcinoma with 50% of the Ki-67 index in the histopathological report. After 3 wk, we performed a total pancreatectomy and a total gastrectomy. Four weeks after the 1(st) operation, we detected a recurrence at the operative bed on his left hip, and subsequently removed the recurring mass. The patient was receiving chemotherapy based on etoposide and cisplatin treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
