Fulltext Arteriovenous malformation of the stomach: a rare cause of upper gastrointestinal bleeding

Latar NH, Phang KS, Yaakub JA, Muhammad R

Med J Malaysia, 2011 Jun;66(2):142-3.
PMID: 22106696 MyJurnal

Haemorrhage arising from gastric arteriovenous malformation (AVM) is rare and normally occurs in the elderly. Bleeding gastric AVM presenting in the younger age group is even rarer. We report a case of a 14 year old boy who presented with recurrent episodes of haematemesis. He subsequently underwent a proximal gastrectomy and the histological examination confirmed a gastric AVM. After reviewing the literature we believe this is the youngest ever reported case of bleeding gastric AVM reported in English literature.

Lethal hemorrhage from a ureteric-arterial-enteric fistula diagnosed by postmortem CT angiography

Rashid SN, Bouwer H, O'Donnell C

Forensic Sci Med Pathol, 2012 Dec;8(4):430-5.

Fistula formation following pelvic surgery and radiotherapy, including ureteric-arterial fistulas (UAF), is well documented, however, ureteric-arterial-enteric fistula is extremely rare. Conventional autopsy is usually required for the definitive diagnosis of pelvic vascular fistulas although an accurate diagnosis can still be complicated and challenging. The role of post-mortem computed tomography (PMCT) as an adjunct to conventional autopsy is well documented in the literature. One of the limitations of PMCT is the diagnosis of vascular conditions. Post-mortem computed tomography angiography (PMCTA) is a recently introduced technique that can assist in detecting such pathology. We present a case of post-radiotherapy ureteric-arterial-enteric fistula presenting as massive rectal and vaginal bleeding diagnosed prior to autopsy on PMCTA. The role of PMCTA in the diagnosis of such a UAF has not previously been reported in the literature.

Calibre persistent submucosal artery of the jejunum: a rare cause of massive gastrointestinal bleeding

Wan Muhaizan WM, Julia MJ, Al Amin D

Malays J Pathol, 2002 Dec;24(2):113-6.
PMID: 12887171

Historically a calibre persistent submucosal artery was most often described in the stomach. However in later years it was also discovered in the duodenum and jejunum. It is an uncommon and important cause of massive gastrointestinal bleeding in which failure of detection and early intervention would lead to death. In this paper we report a 27-year-old man with no significant medical history who presented at the emergency unit for recurrent melaena, haematochezia and hypotension. Initial investigations failed to localize the source of bleeding. Emergency exploratory laporatomy revealed a small jejunal mucosal nodule that was actively spurting blood. Histopathological evaluation identified a calibre persistent submucosal artery.

PMID: 22292642

BACKGROUND: Knowledge is believed to be a driving factor for patients' early presentation for healthcare. This study was conducted to assess knowledge of colorectal cancer among subjects presenting with rectal bleeding and to determine its association with late presentation.

METHODS: A cross-sectional study of 80 patients with rectal bleeding, aged 40 and above, was conducted between December 2008 and June 2009 in the endoscopy unit, University Kebangsaan Malaysia Medical Centre. The research instruments used in this study was a self-administered questionnaire including data on duration of rectal bleeding, first medical consultation and knowledge of colorectal cancer.

RESULTS: Sixty percent of subjects with rectal bleeding delayed seeking medical advice. Subjects were more aware of symptoms of non-colorectal cancers compared to symptoms of colorectal cancer. The majority of subjects (63.8%) correctly identified rectal bleeding as a symptom but were not aware of the best screening method to detect colorectal cancer. Half of the subjects knew increasing age and genetic background to be risk factors for colorectal carcinoma. However, knowledge of colorectal cancer was not found to be significantly associated with delay in seeking help.

CONCLUSION: Findings indicate poor awareness of colorectal cancer among the subjects. Although public education of colorectal cancer is important for early presentation on rectal bleeding, further studies are advocated to evaluate other factors influencing patients' help seeking behavior other than knowledge.

Fulltext A Randomized Controlled Trial of Novel Treatment for Hemorrhagic Radiation Proctitis

Pui WC, Chieng TH, Siow SL, Nik Abdullah NA, Sagap I

Asian Pac J Cancer Prev, 2020 Oct 01;21(10):2927-2934.
PMID: 33112550 DOI: 10.31557/APJCP.2020.21.10.2927

BACKGROUND: Various methods have been used for treatment of hemorrhagic radiation proctitis (HRP) with variable results. Currently, the preferred treatment is formalin application or endoscopic therapy with argon plasma coagulation. Recently, a novel therapy with colonic water irrigation and oral antibiotics showed promising results and more effective compared to 4% formalin application for HRP. The study objective is to compare the effect of water irrigation and oral antibiotics versus 4% formalin application in improving per rectal bleeding due to HRP and related symptoms such as diarrhoea, tenesmus, stool frequency, stool urgency and endoscopic findings.
METHODS: We conducted a study on 34 patients with HRP and randomly assigned the patients to two treatment arm groups (n=17). The formalin group underwent 4% formalin dab and another session 4 weeks later. The irrigation group self-administered daily rectal irrigation at home for 8 weeks and consumed oral metronidazole and ciprofloxacin during the first one week. We measured the patients' symptoms and endoscopic findings before and after total of 8 weeks of treatment in both groups.
RESULTS: Our study showed that HRP patients had reduced per rectal bleeding (p = 0.003) in formalin group, whereas irrigation group showed reduced diarrhoea (p=0.018) and tenesmus (p=0.024) symptoms. The comparison between the two treatment arms showed that irrigation technique was better than formalin technique for tenesmus (p=0.043) symptom only.
CONCLUSION: This novel treatment showed benefit in treating HRP. It could be a new treatment option which is safe and conveniently self-administered at home or used as a combination with other therapies to improve the treatment outcome for HRP.

Fulltext Gastroprotective effects of Corchorus olitorius leaf extract against ethanol-induced gastric mucosal hemorrhagic lesions in rats

Al Batran R, Al-Bayaty F, Abdulla MA, Al-Obaidi MM, Hajrezaei M, Hassandarvish P, et al.

J Gastroenterol Hepatol, 2013 Aug;28(8):1321-9.
PMID: 23611708 DOI: 10.1111/jgh.12229

BACKGROUND AND AIM: Corchorus olitorius is a medicinal plant traditionally utilized as an antifertility, anti-convulsive, and purgative agent. This study aimed to evaluate the gastroprotective effect of an ethanolic extract of C. olitorius against ethanol-induced gastric ulcers in adult Sprague Dawley rats.
METHODS: The rats were divided into seven groups according to their pretreatment: an untreated control group, an ulcer control group, a reference control group (20 mg/kg omeprazole), and four experimental groups (50, 100, 200, or 400 mg/kg of extract). Carboxymethyl cellulose was the vehicle for the agents. Prior to the induction of gastric ulcers with absolute ethanol, the rats in each group were pretreated orally. An hour later, the rats were sacrificed, and gastric tissues were collected to evaluate the ulcers and to measure enzymatic activity. The tissues were subjected to histological and immunohistochemical evaluations.
RESULTS: Compared with the extensive mucosal damage in the ulcer control group, gross evaluation revealed a marked protection of the gastric mucosa in the experimental groups, with significantly preserved gastric wall mucus. In these groups, superoxide dismutase and malondialdehyde levels were significantly increased (P < 0.05) and reduced (P < 0.05), respectively. In addition to the histologic analyses (HE and periodic acid-Schiff staining), immunohistochemistry confirmed the protection through the upregulation of Hsp70 and the downregulation of Bax proteins. The gastroprotection of the experimental groups was comparable to that of the reference control medicine omeprazole.
CONCLUSIONS: Our study reports the gastroprotective property of an ethanolic extract of C. olitorius against ethanol-induced gastric mucosal hemorrhagic lesions in rats.
