Purpose
No evidences supporting or not the use of intra-abdominal drain (AD) in minimally invasive right colectomies have been published. This study aims to assess the outcomes on its use after robotic or laparoscopic right colectomies.
Methods
This is a multicenter propensity score matched study including patients who underwent minimally invasive right colectomy with (AD group) or without (no-AD group) the use of AD between February 1, 2007, and January 31, 2018. AD patients were matched to no-AD patients in a 1:1 ratio. Main outcomes were postoperative morbidity and mortality and anastomotic leak.
Results
A total of 653 patients were included. Of 149 (22.8%) no-AD patients, 124 could be matched. The rate of postoperative complications (AD n = 26, 21% vs. no-AD n = 26, 21%; p = 1.000), mortality (AD n = 2, 1.6% vs. no-AD n = 1, 0.8%; p = 1.000), anastomotic leak (AD n = 2, 1.6% vs. no-AD n = 5, 4.0%; p = 0.453), and wound infection (AD n = 9, 7.3% vs. no-AD n = 6, 4.8%; p = 0.581) did not significantly differ between the groups. Time to oral feeding was significantly shorter in the no-AD group [2 (1–3) vs. 3 (2–3), p = 0.0001]. The median length of hospital stay was 8 (IQR 7–9) in the AD group while it was 6 (IQR 5–9) in the no-AD group (p = 0.010).
Conclusions
In conclusion, the use of AD after minimally invasive right colectomies has no influence on postoperative morbidity and mortality rates.
