General Surgery in Milwaukee, Mequon, Glendale, Cudahy, Germantown, Saukville and Waukesha

When you need surgery, you want a surgeon who treats you like a person, not a procedure. The general surgeons at Madison Medical handle the full range of abdominal, soft tissue, and emergency conditions, and they do it at locations across Milwaukee, Mequon, Glendale, Cudahy, Germantown, Saukville, and Waukesha. You get board certified expertise close to home, without the long drive to a downtown hospital campus.

What General Surgery Treats

General surgery covers a wide range of conditions. Your surgeon might remove a diseased gallbladder, repair a hernia, take out an inflamed appendix, or address a growth that needs a closer look. Many of these procedures are scheduled in advance. Others, like appendicitis, show up without warning and need same-day attention.

Common Procedures We Perform

  • Gallbladder removal (cholecystectomy), often done laparoscopically for a faster recovery
  • Hernia repair, including inguinal, umbilical, hiatal, and ventral hernias
  • Appendectomy, available 24/7 for emergency cases
  • Removal of growths, tumors, and skin lesions from soft tissue and organs
  • Thyroid and other endocrine gland surgery
  • Emergency abdominal surgery for bleeding, infection, obstruction, or perforation

Each procedure gets the same standard of care, whether you're at our Mequon clinic or our Waukesha office.

What You Can Expect

Your first visit is a real conversation. Your surgeon reviews your scans and test results, walks through your options, and answers your questions before any decision gets made. If surgery is the right path, our team tells you exactly how to prepare, from what to eat the night before to what to bring on the day of your procedure. After surgery, we give you clear instructions for home recovery and schedule follow-up visits to track your healing.

You get a team that has performed these procedures hundreds of times. Our surgeons favor minimally invasive techniques whenever possible, which means smaller incisions, less pain, and a quicker return to your routine. Many procedures are outpatient, so you go home the same day. And if an emergency hits outside business hours, our surgeons are available around the clock.

We also coordinate your full course of care. Your surgeon works with your primary care doctor and any specialists involved in your case, so nothing falls through the cracks between your diagnosis and your recovery.

Patients often ask how soon they can return to work or normal activity after a general surgery procedure. The honest answer depends on the operation. A laparoscopic gallbladder removal might keep you out of work for a few days. A more involved hernia repair could mean two to three weeks before you're back to full activity. Your surgeon gives you a specific timeline based on your procedure, your job, and your overall health, not a generic estimate.
