Laparoscopic gastrectomy
Four or five small holes are made in the abdomen, and a camera and slender instruments are used to remove part or all of the stomach and the surrounding lymph nodes. Korea has verified its effect in early and locally advanced stomach cancer with two large randomized controlled trials.
Background: The KLASS-01 (1,416 stage I stomach cancer patients) and KLASS-02 (1,050 locally advanced stomach cancer patients) randomized controlled trials led by the Korean Laparoendoscopic Gastrointestinal Surgery Study Group[1][2]
| Advantages | Limitations |
|---|---|
| Small wounds, less pain, quicker recovery; KLASS-01: 5-year cancer-specific survival in stage I stomach cancer 97.1%, comparable to open surgery (97.2%); KLASS-02: locally advanced stomach cancer, 3-year relapse-free survival 80.3% vs 81.3%, with fewer early complications (15.7% vs 23.4%) | May need conversion to open surgery when the tumor is too large or invades nearby organs; Demands a lot of surgical experience |
