Summary
Hand-assisted laparoscopic surgery (HALS) for colon cancer offers shorter operative times and better lymph node yield compared to totally laparoscopic surgery (LAP). While LAP results in a smaller incision, HALS provides comparable outcomes with potential clinical advantages.
Area of Science:
- Surgical Oncology
- Minimally Invasive Surgery
- Colorectal Cancer Treatment
Background:
- Laparoscopic surgery is a viable option for colorectal cancer.
- Hand-assisted laparoscopic surgery (HALS) and totally laparoscopic surgery (LAP) are compared for oncologic colon resection.
Purpose of the Study:
- To evaluate the efficacy of HALS versus LAP for segmental oncologic colon resection.
- To compare lymph node harvest, operative times, blood loss, pedicle length, incision length, and hospital stay.
Main Methods:
- Retrospective review of 40 patient charts (22 HALS, 18 LAP) undergoing elective oncologic segmental colon resection.
- Data collected on lymph node yield, operative times, blood loss, pedicle length, incision length, and hospital stay.
Main Results:
- HALS showed significantly higher lymph node yield (16 vs. 8 nodes) and shorter operative times (120 vs. 156 min).
- LAP resulted in a smaller incision (7 cm vs. 5.5 cm).
- Hospital stay, pedicle length, and blood loss were comparable between groups.
Conclusions:
- HALS is associated with shorter operative times and more lymph nodes harvested compared to LAP.
- Both techniques offer equivalent hospital stays, pedicle lengths, and intraoperative blood loss.
- The smaller incision in LAP has doubtful clinical significance.
