Abdominal hernia are small (or large) openings in the abdominal wall (the tough tissue that encloses your abdominal cavity (stomach, colon, small intestine etc). Normally the abdominal wall is complete, ie there are no openings in it. When a hernia is present, an opening/hole in the abdominal wall allows some the abdominal contents to come out through this hole. Small hernias often go undiagnosed and are completely harmless. In large abdominal hernias your bowel can ’spill out’ of the abdomen and then it looks like you have a bulge on your abdomen. When you cough or strain, this bulge becomes bigger. Aside from looking strange, these hernia can be dangerous in that the bowel that has spilled out of the abdominal cavity can become obstructed and require surgery.
Small, undiagnosed hernias are generally completely harmless. However, in Plastic Surgery they can represent a hidden trap. Yesterday while performing a tummy tuck, I came across a small hernia right next to the belly button. It was less than a centimeter in diameter, and became visible only when I pulled on the abdominal wall. For the purpose of this tummy tuck, this hernia was completely harmless. I used a permanent suture to close the opening and moved on with my procedure. HOWEVER, if this patient was having a liposuction procedure done, I can only imagine with horror how a liposuction cannula could enter the abdominal cavity through this opening and cause a bowel injury. So now the question is, how do you avoid this potentially devastating complication? I have though a lot about this problem. I reviewed the literature on bowel perforations and liposuction. This is a rare complications and most published articles talk about case reports. One paper suggested performing this procedure under local anesthesia so that if there is any intra-abdominal injury, the patient would feel pain right away and then the injury could be treated right away instead of waiting until the patient get sick. None of the articles have investigated how the actual injury has happened. It is my theory at this time that if a bowel perforation ever happens, it is most likely through a pre-existing hole in the abdominal wall. I find it difficult to believe that a blunt tip liposuction cannula could rip through the rough abdominal fascia unless a large amount of force is used and the cannula is directed straight into the fascia.
