Abstract:Described is a 59 year old Japanese man With malignant lymphoma involving the stomach, duodenum, terminal ileum, colon and rectum, who developed early gastric carcinoma. Repeated gastroduodenoscopy revealed various appearances of the gastrointestinal involvement in malignant lymphoma, such as giant folds, polypoid lesions, and ulcerations, in addition to a depressed lesion of early gastric carcinoma. Colonoscopy also showed multiple polypoid lesions throughout the large bowel. Though the gastrointestinal involvement in malignant lymphoma is not rare, diffuse multiple polypoid lesions in the entire large bowel as seen in our case have rarely been endoscopically described.The coexistance of malignant lymphoma and gastric carcinoma in our case might be only a coincidence, though some reports of an increasing incidence of second tumors in patients with malignant lymphoma have been published. Further consideration will be needed as to the relationship between malignant lymphoma and the occurence of a second malignancy.

摘要:

Abstract:The most common histologic type of carcinoma of the esophagus is squamous cell carcinoma. Small cell or oat cell carcinoma is rare. Only 95 cases have been reported as far as we have investigated in both the English and Japanese Literature since the first description by Mckeown1)in 1952.A case of small cell carcinoma of the esophagus concurring with early stomach carcinoma (IIa) in a 71‐year‐old male is reported.Gross, radiological and endoscopic features in sufficient photographs obtained from literature on the 95 cases and in the present case, were analyzed. A major morphological feature of the lesion is well‐defined ulceration with marginal swelling similar to that in a submucosal tumor.From the viewpoint of double cancer, no case of small cell or oat cell carcinoma of the esophagus concurring with early stomach carcinoma is found in the 95 cases reported. Therefore, the present case is thought to be the first reported case of small cell carcinoma of the esophagus concurring with early stomach carcinoma

摘要:

Abstract:Recurrent jaundice or cholangitis resulting from stent clogging is a late complication of endoscopic stenting for malignant biliary obstruction. The cause of clogging is blockage of the stent lumen by biliary sludge. Chemical analysis of this material revealed the presence of calcium bilirubinate, calcium palmitate, mucoproteins and unidentified insoluble materials. Electron microscopic examination of the sludge and stent surface revealed presence of microcolonies of bacteria forming a biofilm. In vitro studies showed that bacteria adhered to the stent surface within two hours of exposing the stent to bacreria. Bacterial B‐glucuronidase causes deconjugation of bilirubin diglucuronide resulting in precipitation of calcium bilirubinate which further contributes to sludge formation. Prevention of late stent clogging should aim at preventing bacterial adherence. The use of broad spectrum antibiotics may sterilize the biliary system but carries a risk of inducing resistant bacteria. Coating the stent surface with antibiotics, chemical or metallic ions may modify the surface and prevent bacterial adherence. In the absence of effective methods to prevent bacterial adherence and biofilm formation, the use of larger stents with bigger lumen may delay the process of clogging. Cleaning with guidewires or brush may unblock the stent but the effect is only temporary. Elective exchange of the stent at a regular interval may help to prevent this complicatio

摘要:

Abstract:After our introduction of endoscopic pancreatic sphincterotomy for treatment of chronic pancreatitis in 1985, our interest has been focused to the value of pure pancreatic juice collection with or without pancreatic sphincterotomy for management of chronic pancreatitis.Through pancreatic sphincterotomy, pain relief was obtained in 13 out of 16 cases with moderate and marked chronic pancreatitis. After pancreatic sphincterotomy extraction of pancreatic calculi using basket forceps was done successfully in 2 of these cases, Spontaneous stone passage occured in the other 2. In pure pancreatic juice collection without pancreatic sphincterotomy, pain relief was seen in 6 out of 13 cases with mild and moderate chronic pancreatitis. The protein plug was simultaneously aspirated during the procedure in 3 cases.Recently, we have indicated in these patients both pancreatic sphincterotomy and pure pancreatic juice collection and noted pain relief was obtained in all of the 8 cases with this approach. With an improvement in the technology of pancreatic drainage, these endoscopic treatment modalities may be possibly useful to stop the progression of chronic pancreatitis.

摘要:

Abstract:The mucus producing tumor of the pancreas (MPT) is now drawing attention because of its characteristic clinical features. It is characterized by abundant secretion of mucin into the cystic cavity or the main pancreatic duct and relatively benign biological behavior. In this paper, endoscopic characteristics of MPT and the role of pancreatoscopy in the diagnosis of this entity are discussed. Eight cases of MPT with various histological backgrounds were examined with pancreatoscopy. Six cases underwent peroral pancreatoscopy and intraoperative pancreatoscopy was performed in four cases. The endoscopic findings of MPT are summarized as follows: 1) Granular change of the epithelium of the pancreatic duct. 2) Papillary tumor with dilatation of capillary vessles on its surface. 3) Irregularity or detachment of the epithelium of the pancreatic duct. The findings mentioned above in 1), 2) and 3) were obtained in three cases, two cases, and two cases, respectively. Except in one case, the border of the lesion with the neighboring normal mucosa was well identified.We conclude that pancreatoscopy is a quite useful diagnostic tool in cases of MPT, especially for determining the extent of the lesion.
