Laparoscopic and open surgery for colon cancer retrieve a similar number of lymph nodes, irrespective of patient BMI. Standardized surgical techniques ensure consistent lymph node recovery for both approaches.

Area of Science:

Oncology
Surgical Oncology
Gastrointestinal Surgery

Background:

Colorectal cancer is a leading global malignancy, underscoring the importance of accurate lymph node staging.
Lymph node retrieval is crucial for determining treatment strategies and patient prognosis in colon cancer.
The influence of surgical approach and body mass index (BMI) on lymph node yield remains a subject of debate.

Purpose of the Study:

To investigate the impact of surgical approach (laparoscopic vs. open) on lymph node retrieval in colon cancer.
To determine if patient body mass index (BMI) affects the number of lymph nodes recovered during surgery.
To compare lymph node yield patterns between laparoscopic and open colon cancer resections.

Main Methods:

Retrospective analysis of 560 patients undergoing colon cancer surgery (2018-2023).

Keywords:

body mass index colorectal cancer fat clearance techniques laparoscopic surgery lymph nodes

Comparison of mean lymph node retrieval between laparoscopic and open procedures.

Utilized violin plots for distribution analysis and assessed BMI's effect on lymph node recovery.

Emphasized standardized surgical techniques and consistent fat clearance protocols.

Main Results:

No statistically significant difference in mean lymph node retrieval between laparoscopic (15.89) and open (15.98) surgeries (p=0.9166).
Violin plot analysis revealed overlapping lymph node yield distributions for both surgical approaches (p=0.6270).
Body mass index (BMI) did not significantly impact the number of lymph nodes retrieved.

Conclusions:

Laparoscopic and open surgery provide comparable lymph node recovery in colon cancer, meeting oncological standards.
Surgical approach and patient BMI do not significantly influence lymph node yield.
Standardized surgical practices are key to achieving consistent and reliable lymph node retrieval outcomes.
