Background: Surgical site infections after gastrointestinal perforation with peritonitis have significant morbidity, increased hospital stays, and cost of treatment. The appropriate management of these wounds is still debatable., Methods: Patients undergoing surgery for gastrointestinal perforation with peritonitis via midline incision were screened for inclusion. After the closure of the midline fascia, patients were randomized into an open negative pressure wound therapy group (application of negative pressure wound therapy and attempted delayed closure at day 4) or a standard care group (no negative pressure wound therapy and attempted delayed closure at day 4). Postoperative outcomes, including surgical site infection till 30 days, were compared between the groups. This was assessed by an independent assessor not involved in the study for delayed closure. Although a priori sample size was calculated, an interim analysis was performed due to slow recruitment during the COVID pandemic. After interim analysis, a continuation of the trial was deemed unethical and terminated., Results: Ninety-six patients were assessed, and 69 were randomized (34 in the negative pressure wound therapy group and 31 in the standard care group). The age, body mass index, comorbidities, blood loss, operative time, and stoma formation were comparable. The surgical site infection was significantly lower in the negative pressure wound therapy group compared to the standard care group (6 [18%] vs 19 [61%], P < .01). The number needed to prevent 1 surgical site infection was 2.3. In a subgroup analysis, the use of negative pressure wound therapy also significantly decreased the rate of surgical site infection in stoma patients (4 [30.7%] vs 9 [69.3%], P = .03)., Conclusion: Open negative pressure wound therapy significantly decreases the incisional surgical site infection rate in patients with a dirty wound secondary to gastrointestinal perforation with peritonitis., (Copyright © 2023 Elsevier Inc.

Background: Postoperative complications of surgical incisions are frequent in liver transplantation. However, evidence justifying the use of incisional negative pressure wound therapy to improve surgical wound outcomes remains limited., Methods: Participating patients were randomly assigned to receive incisional negative pressure wound therapy or standard surgical dressing on the closed surgical incision of the liver transplantation. The primary endpoint was surgical site infection incidence 30 days postoperatively. The secondary endpoints included surgical site events (ie, surgical site infection, dehiscence, hematoma, and seroma) and wound quality of life., Results: Between December 2018 and September 2021, 108 patients (54 in the incisional negative pressure wound therapy group and 54 in the control group) were enrolled in this study. The incidence of surgical site infection at 30 days postoperatively was 7.4% in the treatment group and 13% in the control group (P = .34). The rate of surgical site events was similar in the treatment in the and control group (27.8% vs 29.6%, P = .83). In relation to wound quality of life, the mean score was 75.20 ± 7.27 in the incisional negative pressure wound therapy group and 72.82 ± 10.57 in the control group (P = .23)., Conclusion: The prophylactic use of negative pressure wound therapy on primarily closed incisions did not significantly reduce incisional surgical site infection and surgical site event rates after liver transplantation compared with standard surgical dressings., (Copyright © 2022 Elsevier Inc.

Background: Neck discomfort and voice change are common complications after thyroidectomy. These symptoms might be due to damaged laryngeal nerves, intrinsic structures, or extralaryngeal muscles. They can also occur without injury to any structure as with wound adhesion after thyroidectomy. The objective of this study was to determine causes of neck discomfort and voice change after thyroidectomy and to evaluate the effect of wound massage on symptom relief., Methods: Forty-five female patients who underwent total thyroidectomy were included (21 in the experimental group and 24 in the control group). Wound massage was used as an intervention to release surgical adhesion. After wound massage education, participants in the experimental group received wound massage from 4 to 12 weeks after thyroidectomy. Analysis was performed for both groups., Results: No laryngeal pathology was found after thyroidectomy. The experimental group had significantly better recovery from surgical adhesion and subjective visual analog scale, voice impairment score, and swallowing impairment score (all P < .01) compared with the control group. Voice analysis results associated with laryngeal movement (speaking fundamental frequency, voice range profile maximum, voice range profile range) also indicated significant recovery (P < .01) in the experimental group. These results indicate that local adhesion after thyroidectomy might affect general movement of the larynx and that wound massage could help patients recover normal general movement of the larynx., Conclusion: Neck discomfort and voice change after thyroidectomy are related to local wound adhesion, possibly associated with impairment of laryngeal vertical movement. Release of wound adhesion could help patients recover from neck discomfort and voice changes after thyroidectomy., (Copyright © 2018 Elsevier Inc. All rights reserved.)
