Isolated rectal cancer surgery: a 2007-2014 population study based on a large administrative database

Area of Science:

• Surgical Oncology
• Minimally Invasive Surgery
• Health Services Research

Background:

• Laparoscopic rectal cancer resection is technically demanding, requiring specialized surgeon and institutional expertise.
• Existing literature supports laparoscopy's safety, efficacy, and efficiency for rectal cancer (RC) treatment.
• Generalizability of laparoscopic outcomes across diverse patient and hospital settings remains a consideration.

Purpose of the Study:

• To analyze the utilization of laparoscopic rectal cancer resections in the Veneto region of Italy.
• To identify patient and hospital characteristics associated with the adoption of laparoscopic approaches for RC.
• To evaluate trends and disparities in laparoscopic RC resection rates.

Main Methods:

• Retrospective cohort study utilizing administrative data from Veneto region hospitals (2007-2014).
• Analysis of 4953 rectal resections performed for rectal cancer during the study period.
• Comparison of patient demographics, hospital characteristics, and outcomes between laparoscopic and open surgery.

Main Results:

• Laparoscopic RC resection rates increased significantly, reaching 52% by 2014, attributed to improved equipment and surgeon expertise.
• Laparoscopic surgery demonstrated a significantly shorter mean length of hospital stay compared to open surgery, indicating cost-effectiveness.
• Disparities in laparoscopic adoption were observed across hospitals, with underutilization in older patient groups despite demonstrated safety.

Conclusions:

• Laparoscopic rectal cancer resection is increasingly adopted in the Veneto region, driven by technological advancements and surgical skill.
• The laparoscopic approach offers significant benefits in terms of reduced hospital stay and potential cost savings.
• Addressing disparities in access, particularly for elderly patients, is crucial to ensure equitable benefit from minimally invasive techniques.
