The Division of Upper Gastrointestinal (UGI) Surgery offers a comprehensive range of modern medical treatments, clinic-based therapies, and advanced surgical procedures for patients with oesophageal, gastric, and related conditions.
Peroral Endoscopic Myotomy (POEM) is a minimally invasive procedure used to treat achalasia, a condition where the muscles of the oesophagus (food pipe) don’t work properly, making it hard for food to reach the stomach. The procedure is done through the mouth using a thin, flexible tube (endoscope)— so there are no external cuts or incisions. The goal is to relax the tight muscle at the lower end of the oesophagus (called the lower oesophageal sphincter), allowing food to pass into the stomach more easily. POEM has become a popular and effective treatment with low risk and good long-term results.
Pressurised Intraperitoneal Aerosol Chemotherapy (PIPAC) is an innovative treatment for advanced cancers that have spread to the lining of the abdomen (peritoneum), such as colon, stomach (gastric), and ovarian cancers. In this approach, chemotherapy is delivered as a fine mist (aerosol) directly into the abdominal cavity during a minimally invasive (keyhole) surgery. This allows the medicine to spread evenly and reach the cancer more effectively, with fewer side effects than traditional chemotherapy.
While surgery is often a key component in the treatment of early-stage cancer, some patients may benefit from upfront systemic therapy to shrink the tumour before surgery. This approach can improve the chances of a successful operation and, in some cases, reduce the risk of recurrence.
At National University Hospital (NUH), we conduct regular Multidisciplinary Team (MDT) meetings, where specialists from different disciplines come together to discuss complex cases. These meetings ensure that each patient receives a comprehensive, personalised treatment plan based on the latest clinical evidence.
Our MDT comprises surgeons, medical oncologists, radiation oncologists, radiologists, and pathologists, work collaboratively to provide patients with the highest standard of care.
