AIM: Sufficient liver function is crucial in extracellular matrix growth, hemostasis, and wound healing. Repeated abdominal surgery is a known risk factor for the development of wound complications. This study aimed to evaluate this high-risk constellation in patients undergoing associated liver partition and portal vein ligation for staged hepatectomy (ALPPS) and repeated liver resections (RLR) in comparison to single liver resection (SLR).
METHOD: Forty patients who underwent ALPPS between 2011 and 2020 were evenly matched with patients undergoing RLR or SLR (n = 40 per group) using propensity scores. Postoperative outcomes were compared and factors associated with wound complications were analyzed.
RESULTS: Postoperative wound complications were significantly more frequent in ALPPS group (p = 0.001). The reoperation rate was not significantly different between the three groups (p = 0.143). However, surgical reintervention due to wound complications occurred more frequently in the ALPPS group in relation to RLR and SLR (17.5% vs. 7.5% and 5% respectively). Length of stay was significantly longer in the ALPPS group (p = 0.033). ALPPS was an independent risk factor for postoperative wound complication (OR = 8.55, 95% CI:1.07-68.44, p = 0.043). Risk factor analysis identified age ≥ 60 years (OR = 27.64, 95% CI:3.09-246.75, p = 0.003), BMI ≥ 30 kg/m2 (OR = 30.21, 95% CI:3.35-271.83, p = 0.002), and low postoperative albumin levels (OR = 168.41, 95% CI:7.76-3651.18, p = 0.001) as independent predictors of postoperative wound complications after major liver resection.
CONCLUSION: Patients undergoing ALPPS and RLR are faced with a high risk of developing wound complications. Older age, obesity, a history of previous abdominal surgery, and a decreased postoperative albumin level were independent risk factors for wound complications.
