List of Bariatric Complications [2017]

Leakage: Leakage can occur from technical, mechanical, or ischemic issues after surgery when fluid leaks out of the staple line.[1]

  • 40% of all complications are short-term leak problems. These are almost always fixed before the patients leave the hospital during post-op testing.

Internal bleeding: Internal bleeding is bleeding inside the body and can occur in tissues or organs.

  • Any organ injury (spleen, etc.)
  • Stricture

Stomach or intestine ulceration: Stomach/intestine ulceration is when stomach acid damages the digestive system causing soreness and pain.

Internal or wound infection: Internal or wound infection include any type of internal or external body parts that get infected due to the surgical operation.

Skin separation (outer bleeding):

  • Band slippage

Overall Complication Rate and Death Rate in 2017

Dr. Valenzuela: 1 reintervention for bleeding “she was the only complication” (gastric sleeve) – 1/460 = 0.22%

Dr. Rodriguez: 2 bleeding (gastric sleeve); 2 leaks (gastric sleeve); 1 obstruction (RNY bypass) – 5/629 = 0.810%

Dr. Cabrera: 2 bleeding (RNY), 1 obstruction (RNY), 2 bleeding (sleeve “because of hiatal hernia repair”) 5/499 = 1.002% or 0.60% without hernia

Dr. Gutierrez: 2 bleeding complications (sleeves) – 2/485 =  0.41%

Overall Complication Rate = 13/2073 = 0.63%

According to a study by Stanford University, 96% of patients did not experience any surgical difficulties at all with VSG surgery. The study looked at 16,000 different sleeve patients in a pool of 270,000 bariatric surgery and metabolic patients. The same study found that the mortality rate for this surgical procedure was just 0.08% after 30 days. While the overall mortality rate for most weight loss surgeries is low (0.14%), sleeve gastrectomy mortality rate numbers are much lower than that low average.[1]
