Pathological Conditions of the Small Bowel Flashcards
Principles of Bowel Resection and
Anastomosis
. Affected bowel must be mobilized
. Pathological tissue is removed with a margin of healthy
tissue
. Adequate blood supply to remaining bowel must exist
. Relatively equal diameter segments of bowel must sewn
together
. Anastomosis should be tension free and leak-proof
. Mesenteric defect closed
. Functional anatomical continuity must be maintained
Meckels diverticulum: S/SX, DX & TX
Signs & Symptoms:
. Peptic ulceration
. Inflammation of ileal
mucosa
. Congenital umbilical fistula, iron deficiency anemia
. Malabsorption
. Neoplastic formation
. Impacted foreign body
. Fistula
. Incarcerated hernia
. Sudden profuse and
painless hemorrhage in child
Diagnostics:
. History
. Radionuclide scans
. GI series
. Endoscopy
Treatment:
. Diverticulectomy
. Bowel resection
Benign Neoplasm: S/SX, DX & TX
Signs & Symptoms:
. Obstruction
. Volvulus
. Bleeding
. Pain
Diagnostics:
. GI series
. CT scan
. Endoscopy
Treatments:
. Resection
Malignant Neoplasms: S/SX, DX & TX
Symptoms/Signs:
. Obstruction,
. Bleeding
. Pain
Diagnostic:
. GI series
. Endoscopy
. CT scan
Treatment:
. Wide resection
Obstruction: S/SX, DX & TX
Symptoms/Signs:
. Various complaints,
. Fluid and electrolyte imbalance
. CT Scan
. Sepsis
. Colic
. Distention,
. Nausea & Vomiting (NV)
. Constipation
Diagnostics
. GI series,
. Barium studies
. CT scan
Treatment:
. Treat the cause (e.g. lysis of adhesions)
. Resection
Crohns Disease: S/SX & DX
Symptom/Signs:
. Decreased body weight
. Chronic illness
. Hypoproteinemia,
. Edema,
. Muscle weakness
. Increased basal metabolic
weight
. Vitamin deficiencies
Diagnosis:
. GI series
. Barium studies
Crohns Disease: TX
Treatment:
Medical
. Treat symptoms
. Manage complications
Surgical
. Treat obstruction,
perforation, abscess formation, bleeding
fistulas.
. Bowel resection if necessary
. Surgical intervention does not treat underlying Crohn’s Disease
