消化道出血是临床常见症状。根据出血部位分为上消化道出血和下消化道出血。临床上根据失血量与速度将消化道出血分为慢性隐性出血、慢性显性出血和急性出血。急性大量出血死亡率约占10%,60岁以上患者出血死亡率高于中青年人,约占30%~50%。但良性结肠息肉引起的急性大失血临床少见,诊治上有其特殊性。本科收治1例.取得较好疗效,现报告如下。  相似文献

肠血管疾患所致的下消化道大出血   总被引:1,自引:0,他引:1  
下消化道出血通常有两类,即非大量(又称活动性出血)和急性大量出血。前者指由于下消化道疾患所引起的肉眼可见血便,包括鲜血便(可有或无血块)、果酱样和暗红色稀便,但尚未引起血液动力学改变,后者则是短时间内大量便血,导致休克且需输血治疗的病例。大出血病国外报告以结肠憩室、肠血管畸形占半数以上。国内憩室病很少见,而肠血管疾患,如肠道血管畸形、肠系膜血管闭塞等引起的急性下消化道大出血,临床上并不少见。  相似文献

下消化道是包括从Trcitz韧带以下至肛门的一段肠管,下消化道出血是指Treitz韧带以下的空肠、回肠、盲肠、阑尾、结肠和直肠肛管病变的出血,根据临床表现可分为急性大出血、显性出血和隐性出血,但由于出血原因复杂,有些部位用常规检查手段难以到达,因此如何早期判断出血部位及性质往往比判断病因更为重要和实际。  相似文献

Small bowel diverticulosis is an uncommon and often asymptomatic condition that is sporadically observed during radiographic examination or laparotomy. Although it is frequently seen in duodenum, jejunal and ileal locations are very rare. The majority of patients with jejunal diverticula have no symptoms. However, they can present with a number of acute and emergent complications with a high rate of mortality. Bleeding from jejunal diverticula occurs in less than 3% - 8% of patients and often present as fresh rectal haemorrhage. This can confuse the clinician since a bleeding source in colon is far more common. We report a patient with acute massive rectal bleeding. Abdominal CT angiography demonstrated a jejunal diverticulum as the bleeding source and the patient underwent resection of the affected segment. She has since remained free of gastrointestinal bleeding. Although jejunal diverticulosis is rare, it is an important differential diagnosis for patients with gastrointestinal haemorrhage of unknown origin as it may cause extensive rectal bleeding. Abdominal CT angiography can localize the bleeding source and resection of the affected bowel and primary anastomosis is the treatment of choice.  相似文献

We have experienced 471 patients with anal bleeding during the past seven years. The Results are as follows: 1. As for the types of disease, incidence of hemorrhoid, colorectal cancer and ulcerative colitis (UC) was high, while that of small intestinal problems was low. 2. In the cases of remarkable bleeding from the lower intestinal tract, massive or acute progressive bleeding was less frequent than expected. 3. Inflammatory diseases were the main causes of massive bleeding. Bleeding by UC was the major indication for urgent operation. In the cases with acute massive hemorrhage, basic complications were often found and the possibility of the diseases of small intestine and blood vessel disorders also should be considered. 4. At the examination of bleeding patients, it is efficient to explore the lower colon and rectum first by colonoscopy or sigmoidoscopy, for most of the bleeding lesions are found in these portions. 5. As for surgical treatment, most of colorectal cancer patients with hemorrhage are able to be operated with wait- and -see management. For UC patients, complete cure operation is possible even if they have high-dose steroid medication.  相似文献

Right-sided colonic diverticular disease is a distinct disease entity uncommon in the West. Occasionally, the condition may be complicated by hemorrhage and present as lower gastrointestinal bleeding. We report a series of 25 cases of bleeding right colon diverticulosis and discuss its presentation and management. Patients were selected from the colonoscopic reports of all 190 patients presented with suspected acute lower gastrointestinal bleeding in National University Hospital, Singapore, from 1988 to 1994. Fifty-seven patients (30%) had bleeding diverticulosis in which 25 patients (44%) suffered from right-sided disease. Sixty-four per cent of patients had a history of hypertension. Patients presented with either fresh blood in stools or melena. Fifteen patients (60%) required blood transfusion (median, 2 units). Colonoscopy showed blood clots in the right colon in 15 cases (60%) and active bleeding from the right colon diverticula in 3 patients (12%). The bleeding stopped spontaneously in 16 patients (64%). The other 9 patients required surgery because of continuous or recurrent bleeding. All had a right hemicolectomy performed. The hospital stay was 13 days in this group, compared with 5 days for those undergoing conservative treatment (P = 0.0004). There were no deaths. No patients had further bleeding episodes during a median 7-month follow-up.  相似文献

重症急性胰腺炎合并出血的影像诊断与介入治疗   总被引:1,自引:0,他引:1  
目的 探讨影像诊断及介入治疗在重症急性胰腺炎患者并发出血时的应用价值。方法 回顾性分析本单位1999年3月至2005年9月间收治的32例重症急性胰腺炎并发出血患者的影像诊断及介入治疗的临床资料。结果 32例患者中以消化道出血为主者8例,以腹腔出血为主者21例,以假性囊肿内出血为主者3例。26例患者通过血管造影证实为假性动脉瘤破裂出血,其中23例行超选择性栓塞以控制出血,8例行多次栓塞治疗,3例栓塞失败后给予垂体后叶素灌注控制出血。另有3例患者经磁共振血管造影检查证实为胰源性门脉高压导致的静脉破裂出血,其中1例通过介入断流和放置支架控制出血。3例患者未找到出血血管,行手术治疗。32例患者中治愈2l例,死亡11例,无1例发生血栓形成及脏器缺血坏死等严重并发症。结论 重症急性胰腺炎并发出血时应尽早行血管造影,同时结合增强CT、磁共振血管造影及消化道内镜迅速明确出血部位及原因,介入治疗可作为控制出血的首选治疗措施,必要时行手术治疗。  相似文献

Bleeding from the gastrointestinal tract represents relatively common diagnostic and therapeutic challenge in clinical work of gastroenterologists and surgeons. Bleeding from the lower GI (LGIB) is mostly caused by pathologic conditions of the colon, although the source of bleeding cannot always be exactly localized, thus rendering optimal and prompt therapy difficult. During two year period, at IlI department of the First Surgical Clinic in Belgrade, we performed 424 colonoscopies for LGIB. According to our results the exact diagnosis was established in about 76% (324 patients) showing a great similarity with the results of other published studies (varying between 74% and 89%). The most common causes of bleeding were diverticulosis (37.11%), polyposis (10.3%) and colorectal cancer (46.14%). Besides that we have mentioned some specific facts involving the diagnosis and treatment of LGIB with an accent on some rare conditions, like angiodysplasia. Review of the diagnostic procedures and treatment modalities of the LGIB is useful for everyone who meets with this type of pathology in clinical practice. The diagnostic approach and the surgical treatment of these patients may represent a great problem, since the planning of the operative procedure can be very difficult and with uncertain result. Based on the literary data and our experience we have tried to set the algorithm of the diagnostics and treatment of the LGIB.  相似文献
