6 years after panniculectomy, lump is present under one side of scar. What can this be?

It's difficult to say what could be occurring without an exam or testing. It certainly could be scar tissue or perhaps a suture abscess. The ultrasound should point you in the right direction.

Thanks for your question. It is difficult to give you a definite answers without examining you in-person. I would return to the surgeon who performed your panniculectomy. Good luck!

Hi cb79, Thank you for your question regarding a lump present 6 years after your panniculectomy and what can could it be. I am glad you healed well and that are you are happy after your panniculectomy. In regards to the lump that you developed 6 years after panniculectomy, this should be work-up with an ultrasound. If your post-op panniculectomy ultrasound does not yield a conclusive diagnosis, you may need a CT scan or even an MRI. In regards to what this lump may be, it could be several things. The differential diagnosis includes a hernia, seroma, hematoma, and scar tissue or fibrosis. Your postoperative panniculectomy lump may be a hernia. A hernia is a hole in one cavity leading to the egress of another cavity’s contents. Hernias can contain a variety of tissues. In the abdominal area, usually, an abdominal hernia is a hole in the anterior abdominal wall which communicates with the peritoneal cavity. This hole can be caused by trauma or congenital defects. The trauma can include heavy lifting and surgical incisions. A hernia can contain fat, or even intestine, which spills from the peritoneal cavity. Your postoperative panniculectomy lump may be a seroma. A seroma is a cavity or ball of serous fluid. Serous fluid is your body’s natural superglue, which helps to glue surfaces together. Sometimes the body makes too much serous fluid and a serous cavity develops. This is much like an egg of serous fluid. Your postoperative panniculectomy lump may be a hematoma. A hematoma is a collection of blood. Much like a seroma, this collection of blood becomes encased in scar tissue. Usually, overtime, the blood in the hematoma is absorbed and a ball or collection of scar tissue is left. Your postoperative panniculectomy lump may be a ball of scar. Another term for scar tissue is fibrosis. Either way, it is a collection of scar. Some of these conditions will require surgery; others conditions may not. If your hernia is of a certain size, it should be surgically repaired. If the seroma is bothersome or contains fluid, I would suggest surgical resection. If the hematoma is large and contains fluid, I would suggest surgical removal to minimize the chance of infection. If the area just demonstrates scar tissue, this may or may not need to be removed.
