Laparoscopic BPD Complications & Side Effects

Because BPD with DS is major surgery, it poses possible complications and side effects, which should be considered before making the decision to have surgery. Complications can occur both early after surgery and later during the recovery period. Although no surgery is risk-free, AtlantiCare's program takes steps to minimize the chance of complications with:

  • Proper treatment
  • Monitoring
  • Support
  • Management

Potential Early Complications Following Duodenal Switch Surgery:

  • Deep vein thrombosis (blood clot)
  • Pulmonary embolism
  • Respiratory complications (such as pneumonia)
  • Gastrointestinal leak
  • Bowel obstruction
  • Infection
  • Bleeding that may require a blood transfusion or possibly a return to the operating room
  • Death.

Potential Later Recovery Period Problems:

  • Hair loss (not permanent for most women)
  • Vitamin deficiencies that may lead to anemia, metabolic bone loss or other problems.
  • Regaining of weight
  • Diarrhea and foul smelling gas, with an average of 3-4 loose bowel movements a day
  • Protein-calorie malnutrition, which might require a second operation to lengthen the common channel
  • Bowel obstruction
