Background: An intraperitoneal closed-suction drain is generally inserted following hepatic resection, for early detection of hemorrhage or bile leakage and to prevent postoperative fluid collection. The objective of our study was to evaluate the feasibility of a recently developed digital-suction power control device (SMARTVACⓡ) by comparing it with a traditional externalized closed-suction drain.
Methods: For 1 month from November 16, 2017, 10 patients were prospectively randomized into either the externalized closed-suction drain (Jackson-Pratt group, n = 5) or digital suction power control device group (SMARTVACⓡ group, n = 5) after elective hepatic resection.
Results: There was no difference in drainage volume from 1 hour to 3 days postoperatively between the two groups. One patient in the Jackson-Pratt group underwent additional percutaneous drainage due to fluid collection around the cut surface of the liver. There were no significant differences between the Jackson-Pratt group and the SMARTVACⓡ group, in terms of the postoperative day of drain removal (5.0 vs. 3.6 days, P = 0.310) and hospital stay (6.8 vs. 6.6 days, P = 0.841). Patient-controlled analgesia (PCA) was initiated immediately after surgery in all patients, and there was no significant difference between the groups in terms of the numerical rating scale score (2.6 vs. 3.6), the number of opioid injections (1 vs. 3, P = 0.262), and the postoperative day on which PCA was stopped (2.8 vs. 2.4, P = 0.310).
Conclusions: Although much more research is necessary, the new digital suction power control device is feasible for postoperative abdominal drainage.
