Results

Within the study period, 42 patients were identified. Of these, 18 (42.9%) were included in the control group and 24 (57.1%) in the ciNPWT group. No statistically significant differences were found in demographic characteristics between the groups (all P > .05). Importantly, mean body mass index (BMI) in the control and ciNPWT groups was 29.65 kg/m2 and 29.67 kg/m2 (P = .629), respectively (Table 1). All patients included in the analysis underwent DIEP flap breast reconstruction, and 35 patients (83.3%) had bilateral reconstruction.

In terms of perioperative variables, no statistically significant differences were found with regards to mean operative time, mean flap weight, and hospital length of stay. Mean follow-up time was 4.8 months for the control group and 5.2 months for the experimental group (P = .127) (Table 2).

In reference to abdominal donor site complications, the most common complication was donor site dehiscence. No cases of seroma, abdominal bulge, or abdominal hernia were reported. Wound dehiscence developed in 2 patients (11.1%) in the control group and 3 patients (12.5%) in the experimental group (P = 1.000). One patient (5.6%) in the control group had an infection of the donor site compared with none (0.0%) in the ciNPWT group (P = .429) (Table 3).
