MECKEL’S DIVERTICULUM
DEFINITION
It is congenital, results from incomplete closure of vitellointestinal duct..
It is the most common congenital anomaly of small intestine.
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.
