Relationship between the gastric myoelectric and mechanical activity in the genesis of ulcers in indomethacin-insulin-treated rats

We have proposed that gastric contractile activity mechanically induces ulcers in the nonsteroid antiinflammatory drug (NSAID)-treated rat. This study examines first the relationship between number (dose) of peristaltic contractions applied to the mucosa and the ulcer score. Second, it examines the relative roles of: altered gastric myoelectrical activity (MEA) resulting from indomethacin (Indo) pretreatment, insulin-induced gastric peristalsis, and a combination of the two in the generation of mucosal lesions. Third, it examines the effect of exogenous prostaglandin on the Indo-altered MEA and relates it to ulcerogenesis. Indo pretreatment increased gastric tone and MEA. In such animals, the dose of peristaltic contractions applied to the gastric wall was related to the ulcer score in a dose-dependent manner. Exogenous prostaglandin (PG) reversed the MEA effect of Indo and reduced ulceration. It is postulated that an altered smooth muscle state secondary to inhibition of prostaglandin synthesis (PG-S) renders the mucosa vulnerable to injury by peristaltic action.This study was supported by the Fast Foundation.     

A Case of a Patient with a Rectal Ulcer Who Had an Unusual Defecation Habit

Abstract: This case report describes a patient with a rectal ulcer who had an unusual defecation habit. Complete healing was recognized colonoscopically after the patient was instructed to break this habit. A polyp of the ascending colon was detected by a barium enema in a 37-year-old man complaining of anal bleeding. He was admitted to our division to undergo a polypectomy. At the time of the polypectomy, a round ulcer, measuring 1 cm in diameter, was detected on the right wall of the rectum 3 cm from the anal verge. A diagnosis of mucosal prolapse syndrome of the rectum could not be made because the patient did not exhibit the characteristic habit of excessive “straining” mentioned by patients with this syndrome, and no characteristic finding of fibromuscular obliteration was found on histological examination of biopsied specimens taken endoscopically from the lesion. Repeated history taking, however, revealed that the patient had the unusual habit of inserting his finger into his rectum after defecation. He broke this habit following instruction to do so. As a result, on colonoscopic examination 15 month later, the ulcer was found to have become a scar:     

美宝胃肠胶囊治疗胃炎和溃疡病的临床观察

目的：探讨美宝胃肠胶囊修复胃炎、胃溃疡等胃肠黏膜病变的治疗作用。方法：随机将40例具有胃黏膜病变的患者（慢性胃炎患者25例，消化性溃疡15例）分为两组：治疗组服用美宝胃肠胶囊及奥美拉唑治疗；对照组单用奥美拉唑治疗，根据临床症状改善情况及胃镜下黏膜修复情况综合评价疗效，并进行组间比效。结果：美宝胃肠胶囊联合奥美拉唑治疗组病人的临床症状改善率，优于单纯接受奥美拉唑治疗的对照组，治疗组的胃镜下病灶修复状况也优于对照组。结论：美宝胃肠胶囊对胃黏膜病变的修复与症状改善有良好的治疗作用。     

大鼠应激性溃疡与胃泌素、胰高血糖素和生长抑素的相关性研究

采用冷束缚法建立大鼠应激性溃疡模型，以探讨胃肠激素与应激性溃疡发病的相关性。实验组置于（４±２）℃环境，３Ｈ，对照组置于（１８±３）℃，３ｈ，分别检测不同时间血清胃泌素、胰高血糖素、生长抑素的水平。结果表明，实验组胃泌素、胰高血糖素水平明显高于对照组，生长抑素水平明显低于对照组。提示胃泌素、胰高血糖素、生长抑素可能从不同的角度参与了应激性溃疡的消长过程。     

筋膜皮瓣治疗小腿顽固溃疡9例报告

Gastric ulceration caused by heater probe coagulation

A double-contrast upper gastrointestinal examination on a woman who had undergone endoscopic heater probe therapy one day earlier for multiple arteriovenous malformations revealed shallow, irregular, and linear ulcers at the sites of heater probe coagulation. Multiple shallow ulcers may therefore develop as a direct complication of heater probe therapy. Radiologists should be aware of this complication to avoid diagnostic confusion in these patients.     

肝源性溃疡的临床观察

目的：研究乙肝后肝硬化患者消化性溃疡的临床特点及治疗转归，探讨内镜下止血及小剂量心得安对肝源性溃疡愈合的影响。方法：肝源性溃疡75例，观察其发病年龄、临床表现、溃疡部位、HP感染率、出血率及7d内止血率及溃疡愈合率等特点，随机分为治疗组37例，内镜下止血 心得安 泰胃美治疗，对照组38例，用维生素B6 泰胃美治疗；另外选单纯性消化性溃疡73例，随机对照2组36例，用维生素B6 泰胃美治疗，对照3组37例，内镜下止血 维生素B6 泰胃美治疗。结果：肝源性溃疡发病年龄较单纯性消化性溃疡晚10年，溃疡部位以复合性溃疡居多和并出血率高，内镜下止血 小剂量心得安可明显提高肝源性溃疡7d内止血率，促进肝源性溃疡愈合率，与对照组具有统计学意义(P＜0．01)。结论：肝源性溃疡难以治愈互易并出血，互以复合性溃疡多见，门静脉高压因素可能从中发挥作用，内镜下注射及喷洒止血剂及口服小剂量心得安及用制酸护肝治疗能有效止血，促进溃疡的愈合。     

Bleeding from gastric ulcer halted by laparoscopic suture ligation

In a 48-year-old Japanese man there was an uncontrollable and recurrent bleeding from a gastric ulcer and laparoscopic surgery was done. Two cannulae were placed in the gastric cavity through the abdominal wall and suture ligation of the bleeding vessel at the posterior wall of the stomach was done under videovisual control with endoscopic guidance. The bleeding ceased, complications were nil, and he remains well.This article reports on surgery done to repair uncontrollable, recurrent bleeding from a gastric ulcer. Two cannulae were placed in the gastric cavity through the abdominal wall and suture of the vessel at the posterior wall of the stomach was done with videovisual control and endoscopic guidance. This approach is concluded to have supplied minimal-access surgery, cost effectiveness, early discharge, less pain, and doctor-patient satisfaction.
