Currently laparoscopic cholecystectomy (LC) and common bile duct exploration (LCBDE) has become the standard surgical procedure for cholecystolithiasis and choledocholithiasis. During the operation cystic duct and vessels are usually controlled by Hem-o-lok clips. However, recently we found clips dropping into CBD in 8 patients during fiberoptic choledochoscope 2-3 months after operation. Therefore, there is risk that clip can migrate during postoperative period, which probably lead to hemorrhage and bile leakage after LC if this occurs within postoperative few days, or even cause recurrent stone in CBD. So, using of Hem-o-lok clips may be not a safe method to control vessels and cystic duct during LC. To our knowledge, this condition has not previously been reported. In our view, other more effective and safe method ligating cystic duct and gallbladder vessels, such as effective and convenient thread knotting method, should be investigated. 相似文献

Summary The clinical suitability of conventional glyceromonooctanoin (GMOC) and ethylenediaminetetraacetic acid (EDTA) containing solvents for the dissolution of common bile duct stones is questionable. To improve the solvent-stone contact and the miscibility with bile, GMOC was hydrophilized by the addition of polyethyleneglycol-caprylglyceride, polyethyleneglycol-sorbitan-etheroleyl-ester, and polyethyleneglycol-sorbitanlaurylester (PEG-GMOC). This product was mixed with a bile acid-EDTA (BA-EDTA) solution in a ratio of 12 (v/v) for cholesterol solubilizing and calcium complexing capacities. To determine clinical efficiency, the new solvent was infused via a nasobiliary tube in 16 patients with endoscopically nonextractable common bile duct stones and compared with a group of 16 patients treated with an alternating GMOC/BA-EDTA regimen. Continuous perfusion with PEG-GMOC-BA-EDTA led to a total (12 patients) or partial (3 patients) disappearance of the stones within 2–15 days. Similarly, alternating GMOC and BA-EDTA treatment dissolved the stones in 12 patients.The average volume of PEG-GMOC-BAEDTA infused contained only 27% of the GMOC applied during the alternating therapeutic regime. This reduction of the GMOC dose was associated with a significant reduction of adverse effects such as emesis, diarrhea and biliary pain. We concluded that GMOC is equally efficient in the new hydrophilized form but it is clearly superior as far as side effects are concerned. In all, this supports its clinical suitability for the dissolution treatment of common bile duct stones.Abkürzungsverzeichnis GMOC

Summary An immunoperoxidase technique has been utilized for the localization of carcinoembryonic antigen (CEA), Secretory component (SC) and lysozyme (LZ) in normal and cancerous common bile duct tissues. Little or no CEA was found in the non-cancerous common bile duct tissues. SC was found in the surface epithelium and accessory gland epithelium and LZ was demonstrated only in the accessory glands. Some inflammatory cells were also positively stained for LZ. In adenocarcinoma, CEA was always present on the luminar border of the carcinoma cells, occasionally with intercellular and intracellular localization. LZ was absent, or only faintly detected in carcinoma. SC was generally distributed in well-differentiated adenocarcinoma cells, but showed a reduced intensity of staining with progressive dedifferentiation. These findings suggest that CEA, SC and LZ could be useful markers providing valuable information in the pathological diagnosis of bile duct carcinoma. 相似文献

The fine structure and histochemistry of human bile duct in obstruction and choledocholithiasis 总被引:1,自引:0,他引:1
Biopsies from the common bile ducts from seven patients undergoing surgery for biliary obstruction due to stones or malignancy were studied histochemically and electron microscopically. The surface of the bile duct is lined by a tall epithelium which extends into diverticula. Apically, they contain some neutral and sialated mucosubstances. Fucosyl residues were found in the Golgi apparatus and along the apical cell membrane. The latter is lined by microvilli. There was a well-developed rough endoplasmic reticulum and Golgi apparatus and a small number of apical secretory droplets. Large numbers of lipid droplets were present basally in some cells. Lipid-containing macrophages were also seen intra-epithelially and in the lamina propria. This suggests a possible pathway for lipid transport. The glands were lined by cuboidal cells, some containing much mucus--sulphated, sialated, and neutral with a basal nucleus. A well-developed endoplasmic reticulum and Golgi apparatus were found with abundant secretory droplets. The glandular epithelium contained lysozyme, alpha-1-antitrypsin, and alpha-1-antichymotrypsin. These may play a protective role. The lamina propria contained scattered smooth muscle cells amongst the fibroblasts and inflammatory cells. 相似文献

The question addressed here is: does the bile duct reactive component of hepatitis C disease progress during the progression of the disease to cirrhosis? The question is important because if the answer to the question is yes, then an important correllated question is: does the bile duct reactive component contribute to the fibrotic change which leads to cirrhosis? The first question is addressed in the present study of a series of liver biopsies taken at the four stages of liver fibrosis in patients with hepatitis C. Sixty-four patients with hepatitis who had been biopsied for staging purposes were reviewed retrospectively. The liver biopsies were routinely stained with antibodies for liver cells, bile duct cells, activated stellate cells and cells in S phase of the cell cycle and histochemical stains for collagen and basement membrane. Selective biopsies were stained for stem cells and oval cells. There was a progressive increase in metaplastic bile ductules but the increase did not reach a significant level until stages III and IV of fibrosis. There was a positive correlation between the number of ductules formed and the stage of liver fibrosis. The incidence of proliferating metaplastic ductules was low and did not change significantly during the progression of the stage of the fibrosis. Stains for oval cells and stem cells were negative. It is concluded that the answer to the question posed is: bile ductule reaction does increase during the development of cirrhosis caused by hepatitis C but the increase is due to bile ductular metaplasia, not due to proliferation. 相似文献

Summary The anatomic relationships of the gastroduodenal artery (GDA) and the posterior superior pancreaticoduodenal artery (PSPD) with the bile duct in their retroduodenal courses were studied in 35 bloc specimens from normal cadavers, injected after removal. The distances between the GDA, the pylorus, and the bile duct were measured in the sagittal plane. The origin and course of the PSPD in relation to the bile duct were studied. The relation of the GDA and the bile duct were divisable into four types: in Type 1 (n=22) the two structures separated progressively, the artery being on the left of the bile ducts; in Type 2: (n=7) the structures approached each other without crossing, Type 3: (n=5) the GDA crossed in front of the bile duct at the level of the first part of the duodenum (D1), Type 4: (n=1) the GDA crossed the bile duct below D1 and ran along its right border. The PSPD originated at the posterior face of D1 in 20% of cases (n=7) and crossed the anterior surface of the bile duct at the posterior surface of D1. In four cases there was no pancreatic tissue between the PSPD and the bile ducs. It follows that the risk of injury to the bile duct when securing hemostasis by transfixing a bleeding duodenal ulcer in the D1 segment is great when the arterial structures (GDA and PSPD) cross the bile duct. This risk is increased when there is no pancreatic tissue between them.
Rapports du conduit cholédoque et des artères rétroduodénales. Incidences sur le traitement chirurgical de l'ulcère duodénal hémorragique
Résumé Les auteurs ont analysé les rapports anatomiques de l'artère gastroduodénale (AGD) et de l'artère pancréatico-duodénale postérieure et supérieure (APDPS) avec le conduit cholédoque dans leur trajet rétroduodénal à partir de 35 blocs duodéno-pancréatiques sains et injectés après prélèvement. Les distances entre l'AGD, le pylore et le conduit cholédoque ont été mesurées dans le plan frontal. Les distances entre l'AGD et le conduit cholédoque ont également été mesurées dans le plan sagittal. L'origine et le trajet de l'APDPS par rapport au conduit cholédoque ont été étudiés. Les rapports de l'AGD et du conduit cholédoque ont été classés en 4 types : Type 1 (n=22) ces deux éléments s'éloignaient progressivement, l'artère se situant à gauche du conduit cholédoque; Type 2: (n=7) ils se rapprochaient sans se croiser; Type 3 : (n=5) l'AGD croisait le conduit cholédoque par en avant à la face dorsale de la partie supérieure du duodénum (D1) ; Type 4 : (n=1) l'AGD croisait le conduit cholédoque au dessus de D1 et cheminait le long de son bord droit. L'APDPS naissait à la face dorsale de D1 dans 20 % des cas (n=7) et croisait la face ventrale du conduit cholédoque à la face dorsale de D1. Dans 4 cas il n'existait pas d'interposition de tissu pancréatique entre l'APDPS et le conduit cholédoque. Il en résulte que le risque de plaie cholédocienne lors de l'hémostase d'un ulcère hémorragique de D1 par des points transfixiants est important lors d'un croisement des éléments artériels (AGD ou APDPS) et du conduit cholédoque. Ce risque est majoré en l'absence d'interposition de tissu pancréatique.相似文献

[B10.A(4R) x B10.PL]F1 mice are low responders to pigeon cytochromec, while [B10.A(2R) x B10.PL]F1 and B10.A mice are high responders.The in vivo site at which the different aliomorphs of the EaIa molecule exert their Ir gene effect on the immune responseto pigeon cytochrome c was examined by creating two differentsets of radiation-induced bone marrow chimeras. [B10.A(4R) xB10.PL]F1(b.m.) B10.A(lrr.) chimeras, which possess antigen-presentingcells (APC) of the low responder, but whose T cells are educatedin a high responder environment, were found to be low respondersto pigeon cytochromec. In contrast, B10.A(b.m.) [B10.A(4R)x B10.PL]F1(lrr.) chimeras, which possess APC of the high respondertype, but whose T cells are educated in a low responder environment,responded to pigeon cytochrome c Addition of B10.A APC to thefirst type of chimera, both prior to antigen priming and atthe time of the secondary challenge in vitro, converted 50%of the animals to responders Furthermore, [B10.A(4R) x B10.PL]F1mice responded to pigeon cytochrome c If they were primed witha 10-fold greater antigen dose and restimulated in vitro Inthe presence of B10.A APC. These results suggest that the primarysite of the Ir gene defect in this system is at the level ofantigen presentation and not in the T cell repertoire. 相似文献
