[A surgical approach to acute intestinal bleeding].
The estimated incidence of lower gastrointestinal bleeding (LGIB) is 20/100,000 patients per year. Of these cases, 70-80% are minor or stop spontaneously and do not present as emergency hospital admissions. Colonoscopy and angiography detect 80-90% of major LGIB, and subsequent endoscopic intervention or embolisation can control approximately 70%. Emergency surgical intervention is required in haemodynamically unstable patients with persistent bleeding. The surgical treatment of choice is directed to resecting the bleeding bowel segment. Subtotal colectomy is performed in patients with colonic bleeding that can not exactly be localized. Segmental colon resection is often associated with rebleeding and not recommended in this situation. Primary anastomosis can usually be performed; elderly patients in reduced condition, however, are candidates for stoma. In case of persistent or recurrent bleeding and differentiation between intestinal and colonic bleeding fails, loop ileostomy may be performed. If the bleeding appears to originate from somewhere in the small bowel, an additional loop jejunostomy may be performed for specification. The mortality from acute LIGB is approximately 5% but increases with emergency surgery. Risk factors are age, comorbidity, and shock on admission.
