The incidence of these complications or side effects can vary significantly depending on the surgeon’s expertise, surgical technique and type of surgery. These risks can include, but are not limited to:

  • Diarrhea
  • Nausea
  • Gallstones

 

Early Complications  

  • Bleeding
  • Blood clots
  • Infections
  • Breathing difficulties
  • Spleen injury
  • Complications due to anesthesia and medications

  • Separation of stitches or staples (depends solely on surgical technique)
