Summary
Laparoscopic surgery for gastric cancer shows faster recovery and better short-term results than open surgery. However, more research is needed to confirm long-term oncological outcomes and establish it as a standard treatment.
Area of Science:
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Laparoscopic surgery for gastric cancer has been utilized globally since 1991, particularly in Japan and Korea.
- Current indications in Japan are limited to early-stage disease (T1/T2, N0).
Purpose of the Study:
- To review the current status and challenges of laparoscopic gastrectomy with lymph node dissection for gastric cancer.
- To evaluate the existing evidence regarding the safety and efficacy of this minimally invasive approach.
Main Methods:
- Systematic review of English-language literature.
- Analysis of studies reporting on laparoscopic gastrectomy for gastric cancer treatment.
Main Results:
- Level 3 evidence indicates laparoscopic gastrectomy is technically safe.
- Short-term outcomes are superior to open surgery, including faster recovery, shorter hospital stays, reduced pain, and improved cosmesis.
- Limited high-level evidence exists for long-term oncological outcomes.
Conclusions:
- Laparoscopic gastrectomy offers significant short-term benefits for gastric cancer patients.
- Further multicenter randomized controlled trials are essential to compare long-term oncological outcomes with open surgery.
- Establishing laparoscopic surgery as a standard treatment requires robust evidence from comparative trials.
