In children, this scan is highly accurate and noninvasive, with 95% specificity and 85% sensitivity; however, in adults the test is only 9% specific and 62% sensitive. Patients with these misplaced gastric cells may experience peptic ulcers as a consequence. Therefore, other tests such as colonoscopy and screenings for bleeding disorders should be performed, and angiography can assist in determining the location and severity of bleeding. Colonoscopy might be helpful to rule out other sources of bleeding but it is not used as an identification tool. Angiography might identify brisk bleeding in patients with Meckels diverticulum.Ultrasonography could demonstrate omphaloenteric duct remnants or cysts. Computed tomography (CT scan) might be a useful tool to demonstrate a blind ended and inflamed structure in the mid-abdominal cavity, which is not an appendix.In asymptomatic patients, Meckels diverticulum is often diagnosed as an incidental finding during laparoscopy or laparotomy. Treatment
Treatment is surgical, potentially with a laparoscopic resection. In patients with bleeding, strangulation of bowel, bowel perforation or bowel obstruction, treatment involves surgical resection of both the Meckels diverticulum itself along with the adjacent bowel segment, and this procedure is called a "small bowel resection". In patients without any of the aforementioned complications, treatment involves surgical resection of the Meckels diverticulum only, and this procedure is called a simple diverticulectomy.With regards to asymptomatic Meckels diverticulum, some recommend that a search for Meckels diverticulum should be conducted in every case of appendectomy/laparotomy done for acute abdomen, and if found, Meckels diverticulectomy or resection should be performed to avoid secondary complications arising from it.
Rarely, a Meckels diverticulum containing ectopic pancreatic tissue can present with abdominal pain and increased serum amylase levels, mimicking acute pancreatitis. Complications
The lifetime risk for a person with Meckels diverticulum to develop certain complications is about 4–6%. Gastrointestinal bleeding, peritonitis or intestinal obstruction may occur in 15–30% of symptomatic people (Table 1). Only 6.4% of all complications require surgical treatment, and untreated Meckels diverticulum has a mortality rate of 2.5–15%.Table 1 – Complications of Meckels Diverticulum:

Bleeding
Bleeding of the diverticulum is most common in young children, especially in males who are less than 2 years of age. Symptoms may include bright red blood in stools (hematochezia), weakness, abdominal tenderness or pain, and even anaemia in some cases.Bleeding may be caused by:

Ectopic gastric or pancreatic mucosa:Where diverticulum contains embryonic remnants of mucosa of other tissue types. Secretion of gastric acid or alkaline pancreatic juice from the ectopic mucosa leads to ulceration in the adjacent ileal mucosa i.e. peptic or pancreatic ulcer. Pain, bleeding or perforation of the bowel at the diverticulum may result. Mechanical stimulation may also cause erosion and ulceration.Gastrointestinal bleeding may be self-limiting but chronic bleeding may lead to iron deficiency anaemia.The appearance of stools may indicate the nature of the bleeding:

Tarry stools: Alteration of blood produced by slow bowel transit due to minor bleeding in upper gastrointestinal tract
Bright red blood stools: Brisk bleeding
Stools with blood streak: Anal fissure
"Currant jelly" stools: Ischaemia of the intestine leads to copious mucus production and may indicate that one part of the bowel invaginates into another intussusception.
