Pentagastrin, histalog, glucagon, secretin, and perchlorate were intravenously injected into mice in order to investigate the hormonal regulation of 99mTc pertechnetate uptake by gastric mucosa. Pentagastrin significantly increased uptake; the effect of histalog was weaker. Secretin did not alter the uptake. Glucagon produced some diminution, and perchlorate significantly inhibited gastric uptake. Hormones may play a role in improving the sensitivity and specificity of diagnostic tests for Meckel's diverticulum.

The literature data concerning the incidence of Meckel's diverticulum in the adult and the frequency of its complications are examined and problems associated with the preoperative diagnosis of this form are discussed. Reference is made to the limitations of abdominal scintiscanning and the encouraging results obtained with superior mesenteric arteriography in diverticular bleeding. Five cases of Meckel's diverticulum in the adult are presented. Stress is placed on the need to explore the ileum during appendicectomy to enable diverticula to be detected and removed, since they are often the cause or the site of complications, even in the adult.

In the last 8 years 15 cases of Meckel's diverticulum were observed, 6 of them with complications: three times inflammation (with two perforations), each once invagination, incarceration and occult bleeding from carcinoids. All complicated and 7 bland diverticula were removed and the intestine oversewed. The postoperative course was normal. Two cases were not treated. Considering possible complications it is recommended to search for a Meckel's diverticulum at each uncomplicated appendectomy or inferior laparotomy and to remove it if found.

A case is described in which the preoperative diagnosis of Meckel's diverticulum was made by scintigraphy after the administration of pentagastrin. Pentagastrin premedication may be helpful in demonstrating ectopic gastric mucosa in patients with gastrointestinal bleeding in whom initial radiopertechnetate scintigraphy is equivocal or normal.

We present a 14 year old girl with a two years' history of colicky abdominal pain associated with the palpation of a tumor in the left upper quadrant of the abdomen. During these two years, the pain and the tumor appeared and disappeared spontaneously several times. In the operation we found a jejunojejunal intussusception, the head being a sessile polyp placed 20 cm from the ligament of Treitz. The pathological examination showed a polyp formed by mucosa similar to the gastric one with chief and parietal cells. We discuss the clinical pictures that can be associated with this pathological entity in this uncommon localization in opposition to the more common settling in Meckel's diverticulum.

The usual scintigraphic presentation of a Meckel's diverticulum is progressive accumulation of Tc-99m pertechnetate within the ectopic gastric mucosa that parallels uptake in the stomach. The authors present a case of an adult with acute gastrointestinal bleeding, negative endoscopic and radiologic evaluation, and atypical scintigraphy. An abnormal focus of uptake appeared at the same time as the stomach but faded away in the 15-minute image before reappearing while the stomach was still progressively accumulating the radioisotope. Meckel's diverticulum was confirmed by surgery. This case emphasizes the importance of scintigraphy in the evaluation of gastrointestinal bleeding, and it further emphasizes that any uptake that cannot be physiologically related is suspicious, even in a young adult.

Neonates with esophageal atresia and tracheoesophageal fistula (TEF) may present with respiratory distress. Intubation and mechanical ventilation may force air from the tracheobronchial tree, through a distal fistula and into the gastrointestinal tract. We present a newborn with TEF who became moribund during mechanical ventilation. High ventilator pressures transmitted via the TEF caused over distention of the gastrointestinal tract and perforation of a Meckel's diverticulum.

The paper discusses the utility and appropriateness of instrumental tests (in particular scintigraphic detection) which are regularly used for the preoperative diagnosis of Meckel's diverticulum. The case is reported of a 9-month-old infant affected by severe recidivating attacks of melena in whom the diagnosis of Meckel's diverticulum was delayed by the repeated negativity of instrumental tests.

Meckel's diverticulum is a common developmental abnormality of the midgut which may present clinically because of complications. This report describes an unusual clinical presentation of a patient with a large leiomyoma of a Meckel's diverticulum.
