Introduction : This study aimed to determine the effectiveness of electrical twitch obtaining stimulation (ETOIMS) as a new modality for managing postoperative somatic pain in patients undergoing open pylorus-preserving pancreaticoduodenectomy (PPPD).
Methods : Among 48 patients who consecutively underwent PPPD, a total of 44 eligible patients were registered and randomly assigned to a control group and ETOIMS group. The ETOIMS group received ETOIMS in the bilateral rectus abdominis muscles at 14 stimulation points under ultrasound guidance immediately after surgery.Pain score (visual analog scale, VAS), peak cough flow (PCF), and gait speed were repetitively measured between a day before surgery and 4 weeks after surgery. Data were analyzed using the linear mixed model and repeated measures analysis of variance.
Results : Data of 38 patients (ETOIMS, 18; control, 20) were finally analyzed. The VAS scores at operation day (mean [SD], ETOIMS, 5.50 [1.95]; control, 6.45 [2.19], P = .02) and at postoperative day (POD) 3 (ETOIMS, 3.22 [1.48]; control, 4.05 [1.57], P = .04) were significantly lower in the ETOIMS group. The improvement of proportional PCF from POD2 to POD7 was greater in the ETOIMS group (mean [SD], ETOIMS, 25.33% [12.19%]; control, 17.13% [9.67%], P = .03). Gait speed recovered to the preoperative level at POD14 in the ETOIMS group (mean [SD], 93.30% [13.91%], P = .20), while gait speed was still lower in the control group (84.64% [16.03%], P < .01).
Conclusions : ETOIMS helps in rapid reduction of postoperative somatic pain developed after PPPD and improves PCF and gait speed.
