Purpose: Drain insertion after proctectomy is common in clinical practice, although the effectiveness of drains has been questioned. However, drains are commonly displaced after surgery. We hypothesized that drain displacement is associated with clinical outcomes and aimed to assess differences in clinical outcomes, such as overall morbidity, including anastomotic leakage (AL), reintervention rates, length of hospital stay, and mortality rates, between patients who experienced displaced drains and those who did not.
Methods: Rectal cancer patients who underwent proctectomy at a single institution between January 2015 and December 2020 were retrospectively reviewed. Clinical characteristics were compared between patients who experienced displaced drains and those who did not. The primary endpoint was the occurrence of reintervention in patients with AL. The secondary endpoints were overall morbidity rates, AL rates, length of hospital stay, and mortality within 30 days.
Results: Among 248 patients who underwent proctectomy, 93 (37.5%) experienced displaced drains. A higher proportion of patients who experienced displaced drains required reintervention due to AL than those who did not experience displaced drains (odds ratio, 3.61; 95% confidential interval, 1.20?10.93; p = 0.016). However, no significant difference was found in the overall morbidity rate, mortality, and length of hospital stay between the groups.
Conclusion: Drain displacement does not worsen outcomes such as overall morbidity rate, mortality, and length of hospital stay after proctectomy but is associated with an increase in the need for reintervention in patients with AL.
