What is Meckel’st can usually be found within about 60-100 cm ofthe ileocecal valve. It is typically 3-5 cm long,runs antimesenterically and has its own bloodsupplyan be present in an indirect hernia, where it isknown as Hernia of Littre. Furthermore, it can beattached to the umbilicus, with the possibility oflocal cysts, torsions of intestine around theintestinal stalk, leading to obstruction, ischemia,and necrosis
Symptoms of Meckel’spproximately 98% of people afflicted with Meckels diverticulumare asymptomatic. If symptoms do occur, they typically appearbefore the age of two.he most common presenting symptom is painless rectalbleeding, followed by intestinal obstruction, volvulus andintussusception.ccasionally, Meckels diverticulitis may present with all thefeatures of acute appendicitis. Also, severe pain in the upperabdomen is experienced by the patient along with bloating of thestomach region.
Diagnosing Meckel’serfrom Meckel’s Scan– Iindications: • Detection and localization of a Meckels diverticulum containing functioning (bleeding) gastric mucosa. • Detection of Barretts esophagus
Diagnosing Meckel’sATIENT PREPARATION:atients G.I. tract should be barium free.Optional) Administer cimetidine prior to injecting theradiopharmaceutical:ive 300 mg intravenously 30 minutes prior to the study. (Dilute to20 mL and infuse over 5 minutes. orive 300 mg orally 60 minutes prior to the study.)c-99m-sodium pertechnetate is given by standard intravenous
Diagnosing Meckel’sTHER CONSIDERATIONS/RATIONALE:– The radiopharmaceutical is actively secreted by gastric mucosa. Although all Meckels diverticula do not contain functioning gastric mucosa, most that bleed do– Patients with active hemorrhage can also be studied with tagged red blood cells. While only 20% of Meckels Diverticula contain ectopic mucosa, greater than 90% of diverticula that bleed do.
Treatment of Meckle’sreatment is surgical, consisting of a resection ofthe affected portion of the bowel.
