Some issues Dr. Peter Langenstroer, MD, MS can help you with:

Laparoscopic Surgery

Laparoscopic surgery is a kind of minimally invasive surgery using a thin, narrow tube called a laparoscope. Usually performed on the abdomen or the pelvic region, the surgeon makes a few very small incisions instead of one large one.

During the procedure, the surgeon inserts the laparoscope, which contains a light and camera that allows the surgeon to see what is happening inside the body. Then tiny tools are placed through the small openings and used to perform the surgery.

The most common laparoscopic surgery is gallbladder removal, but laparoscopic surgery may also be used for the removal of a kidney or appendix, to treat certain cysts and tumors, for bariatric surgery, for some GERD treatments, or for hernia repairs, among others.

Because laparoscopic surgery only uses a few tiny incisions, the scars are minimal and recovery is easier than with open surgery.

I came in for a second opinion. The diagnosis of my condition was very similar to what I had at the University of Wisconsin Hospital and Clinics. The treatment options presented to me were a bit different and more complete. I have to say that I was made to feel at ease with Dr. Langenstroer. He explained the disease diagnosis, the prognosis, and the treatment options that I understood. He was not rushed for time. He encouraged me to ask questions. I have to make my decision on the course of action I will take. I am pleased that I was able to see Dr. Langenstroer at the Medical College of Wisconsin.
