An accurate description of the number, location and relative position of the air sacs and their diverticula in the ostrich is essential for a better understanding of the pathogenesis of air sacculitis in this bird. The air sacs were studied in ten ostriches of varying ages by latex or silicone casting of the respiratory tract and dissection. Results revealed that the air sacs of the ostrich con...

Diverticular disease refers to symptomatic and asymptomatic disease with an underlying pathology of colonic diverticula. Predisposing factors for the formation of diverticula include a low-fiber diet and physical inactivity. Approximately 85 percent of patients with diverticula are believed to remain asymptomatic. Symptomatic disease without inflammation is a diagnosis of exclusion requiring co...

Corrosion casts of the blood vessels in the oral mucosa of Rana esculenta were examined by the scanning electron microscope. Special attention was paid to the palatine capillaries characterized by numerous blind diverticula. Microanatomy and topography of these peculiar vessels suggests their involvement in gas exchange. The diverticula of the capillaries visible in the casts in form of nodules...

Diverticula of the duodenum proceed those of the colon in respect to frequency of location. Incidence at times of autopsy ranges from 15 to 23%. Despite the fact that more than 90% of duodenal diverticulum cases are asymptomatic, complications if they do occur can be calamitous. Perforation is one of these rare complications. Surgical intervention has always been the mainstay for symptomatic/co...

Diverticula of the intestine may be divided into the true and the false. By a true diverticulum is understood one the walls of which are composed of the entire thickness of the intestine; the false diverticulum, on the other hand, is a hernia of the mucosa and submucosa through the muscular wall (yon Rokitansky (1), Leichtenstern (2), Birch-Hirschfeld (3), Orth (34), Itansemann (4), and others)...

Solitary diverticulitis of the cecum is a rare condition in the general population (0.17%) (1). In Western countries, diverticular disease occurs mainly in the left colon, with about 2% in the ascending colon (2). Approximately 80% are found on the anterior side of the cecum (3), and men around 40 years of age are predominantly affected. There are 2 types of diverticula: true diverticula, which...

INTRODUCTION The duodenum is the second seat of onset of diverticula after the colon. Duodenal diverticulosis is usually asymptomatic, but duodenal perforation with abscess may occur. CASE PRESENTATION Woman, 83 years old, emergency hospitalised for generalized abdominal pain. On the abdominal tomography in the third portion of the duodenum a herniation and a concomitant full-thickness breach...

Jejunal diverticula are an uncommon acquired disease that is usually silent and asymptomatic. When symptomatic, they present with chronic nonspecific symptoms like pain, nausea, malnutrition and sometimes with acute presentation like gastrointestinal hemorrhage, peritonitis and obstruction. The majority of complications seen as an acute abdomen similar to appendicitis, cholecystitis or colonic ...

A seventy-year-old male presented with severe myasthenia gravis and an episode of obscure bleeding. There was a history of gastric ulcer leading to Billroth II surgery twenty-five years ago. Upper endoscopy revealed no pathology. Colonoscopy showed a few solitary diverticula and traces of old blood in the terminal ileum. Capsule endoscopy pictured red smear in the upper jejunum. Diverticula wer...
