Problems after Bariatric Surgery

OVERVIEW

Operation types

  • gastric banding
  • gastric bypass
  • sleeve gastrectomy

Key points

  • peritonism may not be apparent in obese patients
  • do not insert a nasogastric tube
  • basic surgical principles still apply
  • thiamine deficiency can occur following a few days of prolonged vomiting in gastric bypass patients, replace early

PROBLEM-BASED APPROACH

Total dysphagia in a band patient

  • suspect acute band slippage
  • gastric ischemia may occur in even an apparently well patient and require emergency surgery
  • urgent bariatric surgery referral

GI bleed

  • suspect anastomotic bleed, marginal ulcer
  • may not be accessible by endoscopy, may require surgery
  • urgent bariatric surgery referral

Intestinal obstruction

  • anastomotic stricture, internal hernia or port site hernia
  • urgent bariatric surgery referral

Chest pain, tachycardia and/or breathlessness

  • suspect MI, PE, gastric pouch problems, anastomotic leak
  • work up DDX as appropriate
  • CT may be impossible or misleading
  • early discussion with surgical team

Abdominal pain

  • suspect subacute obstruction from intenstinal hernia, anastomotic leak
  • work up DDX as appropriate
  • CT may be impossible or misleading
  • early discussion with surgical team

Reflux symptoms, no dysphagia with fluid intake

  • suspect band slip, gastrojejunal stenosis
  • arrange urgent bariatric surgical appointment

Port site infection in a band patient

  • suspect gastric band erosion or infected band
  • treat with antibiotics, arrange urgent bariatric surgical appointment
