- 3. MECKEL’S DIVERTICULUM DEFINITION • It is congenital, results from incomplete closure of vitellointestinal duct.. • It is the most commoncongenital anomaly of small intestine.
- 4. • Arises fromthe antimesentericborder of the ileum, containing all three layersof the bowel withindependent blood supply. • In 20% of cases mucosa contains heterotopic epitheliumlikegastric (commonest—50%), colonicand pancreatic tissues (5%). CLINICALFEATURES • It may be connectedto or communicatedwith theumbilicus through a band or fistula. • oesophageal atresia, • Exomphalos • anorectal malformations • Presentations in Meckel’sDiverticulum • Severe haemorrhage (Maroon-coloured blood).
- 5. • Intestinal obstruction due to bands/adhesions/ intussusception. • Perforation. • Intussusception • Volvulus of small bowel. • Peptic ulceration. • Diverticulitis features mimicacute appendicitis. • Littre‘s hernia—it is presence of Meckel’s diverticulumin hernial sac • It is observedin inguinal/femoral hernia.
- 6. INVESTIGATION • Silent Meckel’s diverticulumfound during • laparotomy • laparoscopy • radioisotope study. • Carcinoid or GIST can occur in Meckel’s diverticulum • Technetium(Tc99) radioisotope scanis very useful • X-rayabdomento see complications like • Obstruction • perforation. • Laparoscopyis very useful. • Enteroclysis/small bowel enema under fluoroscopy
- 7. TREATMENT • AsymptomaticMeckel’s diverticulumcan be left alone whenidentifiedduring laparotomy. • Resectionof a short segment of ileumcontaining Meckel’s diverticulumand end-to-end anastomosis is done. • Meckelian diverticulectomy with closure of enterotomy also can be done • But chances of retaining heterotopictissues and stenosis are higher.
