Xia Shu's father's surgery was completed. The surgery was performed personally by Yang Ping as the chief surgeon, involving a mostly stomach resection and regional lymph node dissection by laparoscope. The entire surgery had almost no bleeding, so the postoperative recovery was expected to be very fast.
Surgery itself can cause trauma and disrupt a person's internal environment. The advantage of minimally invasive surgery is that it causes less trauma to the human body and less disruption to the internal environment, leading to faster recovery after the operation.
Although early-stage stomach cancer may just be a tiny "ulcer," cancer cells inevitably spread to surrounding areas or lymph nodes. To eliminate these small, yet unorganized "evil seeds," the surgery involved not only removing the tiny "ulcer" but also resecting a large part of the stomach including the ulcer and the surrounding lymph nodes.
