Abstract

Purpose: Obesity, neoadjuvant-radiotherapy, tumour proximity to the anal verge and previous abdominal surgery are factors that might increase the intra-operative difficulty of laparoscopic rectal cancer surgery. However, whether patients with these 'high-risk' characteristics are subject to worse short- or long-term outcomes is debated. The aim of this study is to examine the short- and long-term clinical and oncological outcomes of patients receiving laparoscopic rectal surgery with any of these high-risk characteristics and compare them with patients that do not possess any of these high-risk features.

Methods: For the purpose of this study data from consecutive patients receiving laparoscopic rectal cancer resections between 2006 and 2016 from two centres were analysed. High-risk patients were defined as patients with either one of the following characteristics: BMI ≥ 30, neoadjuvant chemoradiotherapy, tumour < 8 cm from the anal verge and previous abdominal surgery.

Results: A total of 313 patients were identified (227 high risk, 86 low risk). Short-term outcomes were similar between the two groups with the exception of blood loss and length of stay, which were higher in the high-risk group (10 vs 2.5 ml, p = 0.045; 7 vs 5 days, p = 0.001). There were no statistically significant differences in 5-year overall survival (79.7% vs 79.8%, p = 0.757), disease-free survival (76.8% vs 69.3%, p = 0.175), distant disease-free interval (84.8% vs 79.7%, p = 0.231) and local recurrence-free interval (100%, 97.4%, p = 0.162) between the two groups.

Conclusion: Similar short- and long-term outcomes can be achieved in high-risk and low-risk patients receiving laparoscopic rectal surgery. The presented data support the suitability of laparoscopic surgery for this group of patients.
