Laparoscopy-assisted distal gastrectomy with D1+beta lymph node dissection shows comparable short-term outcomes to D1+alpha dissection for early gastric cancer. This minimally invasive approach meets oncological requirements.

Area of Science:

  • Surgical Oncology
  • Minimally Invasive Surgery
  • Gastrointestinal Surgery

Background:

  • Laparoscopy-assisted distal gastrectomy (LADG) with D1+beta lymph node dissection is widely used for early gastric cancer in Asia.
  • Clinical advantages of LADG with D1+beta over D1+alpha lymph node dissection require further investigation.

Purpose of the Study:

  • To compare the short-term outcomes of LADG with D1+beta lymph node dissection versus LADG with D1+alpha lymph node dissection.
  • To evaluate the oncological safety and clinical efficacy of both procedures.

Main Methods:

  • A comparative study involving 54 patients undergoing LADG with D1+alpha and 42 patients undergoing LADG with D1+beta.
  • Analysis of surgical findings, clinicopathological data, postoperative course, complications, and nutritional status.

  • Statistical analysis using Mann-Whitney U test and chi-square test.

    • Main Results:

    • D1+beta dissection significantly harvested more N2 lymph nodes (5.9 vs. 2.7, P < 0.01) but showed no difference in total or perigastric lymph nodes retrieved compared to D1+alpha.
    • No significant differences were observed in operation time, blood loss, complication rates, or postoperative recovery parameters.
    • Postoperative blood analysis revealed no significant variations between the two groups.

    Conclusions:

    • LADG with D1+beta lymph node dissection demonstrates comparable short-term outcomes to LADG with D1+alpha.
    • The D1+beta approach is a viable minimally invasive surgical option that fulfills oncological requirements for early gastric cancer.
