Causes of SBO • Adhesions (70%) – usually from previous surgery but TB infection can cause them • Hernia (20%) • Pressure from extrinsic structures (eg. tumour) • Gallstones • Inflammatory bowel disease • Intussusception (especially in young children – it can kill quickly so beware!) • Volvulus • Gynaecological causes in women • 20% of all Surgical admissions
Small Bowel Obstruction Adhesions – what do they look like?
Initial Management of ?SBO • Full history including details of past surgery • Full abdominal exam including PR • Don’t forget hernial orifices (or end up in court)! • Imaging (CXR, AXR, CT, barium) & all bloods • Conservative management unless: • Perforation (imaging) and/or overt peritonism • Irreducible hernia • Palpable mass
Conservative Management • NBM, NG tube and close observations • Patient must have adequate resuscitation before surgery: IV fluids & monitor urine output • Imaging studies: CXR, AXR, CT & barium studies • Closely monitor patient bowel habits!! A SBO can rapidly change from incomplete to complete • Be ready for any deterioration: pain, distension, peritonism, dehydration, sepsis or absolute constipation
Small bowel obstruction: AXR • Dilated loops of small bowel • Central position • Valvulae conniventes • Distal collapse • Barium studies show location of obstruction • ?Absolute indication for surgery
Take home points: SBO • Common surgical emergency • Good history, good examination, appropriate investigations • Conservative management? • Close monitoring for deterioration • Repeat imaging • Peritonism or sepsis = surgery!
TB: Profs Prophecy • Suspect TB in any foreign national with: • Mediastinal/hilar lymphadenopathy • Persistent cervical lymphadenopathy • Pleural effusion • Monoarthritis • Chronic discharging sinus • Small bowel obstruction (7% of all Indian SBO’s!) • 50% of TB presentations are extra-pulmonary! • TB is a notifiable disease: need to trace all contacts for assessment and prophylactic therapy
