محاضرة الباثو عملي
سلايدات ال GIT

اولا ال esophagus
تضمنت المحاضرة الآتي
🌹reflux esophagitis
🌹achalasia
🌹congenital fistula
🌹congenital and acquired esophageal diverticulum
🌹Barrett's esophagus
🌹 squamous cell carcinoma
🌹 Barrett's metaplasia and the associated adenocarcinoma
🌹 esophageal ulcers
🌹 esophageal atresia

اي discontinuation or loss of the esophagus


ثانيا ال stomach
تضمنت المحاضرة
🌹acute gastritis
🌹H pylori associated chronic gastritis
we get neutrophils and secondary lymphocytic follicles
with clear germinal center also
rods or comma shaped bacteria (H . pylori )
🌹 autoimmune associated
chronic gastritis characterized by lymphocytes infiltration and
need continuous checking by the doctor to prevent the development of cancer
🌹peptic ulcer (benign and malignant )
the benign is inverted but the malignant is everted

🌹gastric adenocarcinoma
🌹acute erosive gastritis associated with bleeding
🌹 lymphoma associated with H . Pylori
🌹axial and paraesophageal hiatal hernia most common cause of reflex esophagitis
🌹 hyperplastic polyps
🌹 adenomatous polyps
🌹intestinal metaplasia with highly goblet cells



ثالثا ال small intestine
note /the small intestine is characterized by the presence of villi and microvilli to increase
the surface area for absorption

note / large intestine is rich in goplet cells and libercohn glands with crepts زيما البئر
to increase the absorption of water and convert the lumenal material to semi solid








رابعا ال large intestine
🌹chron's disease
may extend to serosa making
fissures or perforation
characterized by the skip areas
and the

🌹ulcerative colitis
involving all mucosa and no skip areas but continuous disease
🌹familial polyposis colitis
thousands of colic polyps need whole cholecystectomy
🌹 adenomatous polyps
🌹hyperplastic polyps

note /the polyps with vascular core and covering epithelium

note / lung sequstertion
is the presence of lung tissue in
part of the GIT


note / the fistula of the esophagus may completely or partially open to the trachea
