A nonspecific colonic ulcer occurring after hepatectomy: Report of a Case

We herein report the case of a 53-year-old man with a nonspecific acute colonic ulcer whose liver function deteriorated after he had undergone hepatectomy. He was referred to our hospital for a hepatoma caused by hepatitis B virus and a right hemihepatectomy was performed. His liver function was poor after the operation, and minor complications such as pleural effusion and biliary fistula developed. A large amount of melena was seen 29 days after the hepatectomy and he developed hemorrhagic shock. Superior mesenteric arteriography revealed pooling of blood in both the hepatic flexure of the ascending colon and the cecum. An emergency right hemicolectomy was performed. There was a 5 x 1-mm ulcer 18 cm distal to the ileocecal valve. Numerous erosions were observed to be scattered throughout the colonic mucosa. The patient recovered slowly and was discharged 6 months after the hepatectomy. This is the first report of an acute colonic ulcer that could have been caused by liver dysfunction.     

Comparison of acid reduction in antiulcer operations

Background: Three acid-reducing operations have recently been described for the laparoscopic treatment of peptic ulcer disease. These consist of a posterior truncal vagotomy combined with either (1) an anterior seromyotomy (SERO), (2) an anterior highly selective vagotomy (AHSV), or (3) a linear stapled lesser curvature excision (STAP). The purpose of this study was to investigate the physiologic effects of these procedures in terms of basal and maximal acid outputs. Methods: Fifty New Zealand rabbits were prospectively randomized into five open laparotomy groups (n= 10): a control group without vagal manipulation (CON), a bilateral truncal vagotomy with pyloromyotomy group (VP), a SERO group, an AHSV group, and a STAP group. All animals underwent placement of a gastrostomy tube for subsequent gastric secretory analysis. On postoperative day 6, basal acid outputs (BAO) and maximal acid outputs (MAO) following IV pentagastrin stimulation (30 μg/kg/h) were measured. Results were compared statistically using the ANOVA method. Results: Pentagastrin stimulation was associated with a significant increase in MAO in the CON group (p < 0.05 vs BAO); however, this response was effectively blunted in all the experimental groups. There were no differences in BAO or MAO between any of the vagotomized groups (SERO, HSV, STAP, VP). Conclusions: We conclude that the three acid-reducing procedures modified for laparoscopy are equally efficacious in reducing gastric acid secretion and that they compare favorably with VP. To our knowledge, this is the first report comparing basal and stimulated gastric acid secretion between these new acid-reducing techniques. Received: 27 March 1996/Accepted: 17 July 1996     

荆芥连翘汤对促进皮肤溃疡愈合的影响

目的 观察荆芥连翘汤对小鼠皮肤溃疡的治疗作用。方法 建立小鼠皮肤创伤和烫伤两种皮肤溃疡模型．比较荆芥连翘汤以及rhEGF的用药组和自身对照组小鼠皮肤溃疡面积，用昆微镜观察溃疡面炎症细胞浸润情况。结果 和自身对照组相比，荆芥连翘汤可明显缩小小鼠皮肤溃疡面积（P〈0．001），同时炎症细胞浸润显著减少（P〈0．001）；荆芥连翘汤用药组疗效显著优于rhEGF用药组。结论 荆芥连翘汤可明显促进小鼠皮肤溃疡的愈合。     

重庆地区胃,十二指肠疾病患者幽门螺杆菌感染的调查

本文采用分离培养、尿素酶试验及直接涂片革兰氏染色镜检等方法，对１７９８例胃镜受检者的幽门螺杆菌感染情况进行的调查表明，该菌的总感染率为４９．７％，其中浅表性胃炎、十二指肠溃疡、胃溃疡和浅表性胃炎合并十二指肠球炎患者的感染率分别为４７．３％、７５．９％、７０．９％和４９。４％，复合溃疡、胃癌、慢性胃炎、胆汁返流性胃炎和浅表性萎缩性胃炎患者的感染率分别为２７。３％、２３．５％、１５．４％、１３．２％和１２．５％。     

丹参抗大鼠乙酸性十二指肠溃疡作用机制的探讨

目的　探讨丹参抗大鼠乙酸性十二指肠溃疡的作用及机制。方法　按Okabe方法复制大鼠乙酸十二指肠溃疡模型 ,按传统方法测定溃疡指数、溃疡抑制率 ;用放射免疫法测定十二指肠溃疡部位的前列腺环素 (PGI2 )含量。结果　丹参组的溃疡指数显著低于对照组 (P <0 .0 1) ,其溃疡抑制率高于对照组 ,PGI2 的含量亦显著高于对照组 (P <0 .0 1)。结论　丹参具有抗大鼠十二指肠溃疡的作用 ,其机制可能是丹参提高了十二指肠粘膜的防御能力     

幽门螺杆菌在成人消化性溃疡检出的探讨

目的：探讨幽门螺杆菌（HP）感染与消化性溃疡（PU）及年龄、性别的关系。方法：采用快速尿素酶和组织H-E染色法对119例PU病人进行HP感染检测，其中男性96例、女性23例，以上二种方法测定结果均阳性定为HP感染。然后将这些病例按年龄分为三组，即青年组33例，中年组78例和老年组8例。结果：HP总感染率：胃溃疡78．6％，十二指肠球溃疡63．6％，幽门管溃疡66．7％及复合溃疡62．5％，该结果与以前报道相同。各种溃疡的HP感染率在各年龄组间比较及男、女性别间比较无显著性差异（P均＞0．05）。结论：HP感染与PU关系密切，与性别无关，并不与年龄成正比上升。
