Frequently Asked Questions

  • How do I determine if general surgery is the best option for me?

    We assess your condition through a comprehensive evaluation, including a physical exam, imaging tests, and a review of your medical history. If non-surgical treatments are ineffective or if the condition poses a risk to your health, surgery may be the best course of action. Our approach prioritizes patient safety, effectiveness, and long-term health outcomes when recommending surgical intervention.

  • What is the difference between laparoscopic and robotic surgery?

    Both are minimally invasive techniques that use small incisions and specialized instruments to perform surgery with less trauma to the body. Laparoscopic surgery relies on a small camera and hand-held instruments, requiring the surgeon’s direct control. Robotic surgery enhances precision by allowing the surgeon to operate robotic arms using a console, providing improved dexterity and visualization.

  • Is robotic surgery safer than traditional surgery?

    Robotic surgery offers enhanced precision, stability, and flexibility, leading to greater accuracy and fewer complications in complex procedures. While all surgeries carry some risk, robotic-assisted techniques often result in less blood loss, reduced infection risk, and a faster recovery compared to traditional open surgery. The choice of technique depends on the patient’s condition, overall health, and the complexity of the procedure.

  • Will there be visible scarring after skin surgery?

    We use advanced surgical techniques to ensure minimal scarring by placing incisions in less noticeable areas when possible. Proper postoperative wound care, scar management, and follow-up monitoring help promote optimal healing. While some scarring is inevitable, we prioritize both functional and cosmetic outcomes to achieve the best possible results.

  • Will I experience pain after surgery?

    Some level of postoperative discomfort is normal, but we utilize effective pain management strategies tailored to each patient. This may include a combination of medications, localized treatments, and recovery techniques to minimize pain and promote healing. Our team provides detailed post-op care instructions to ensure a smooth and comfortable recovery.
