Tissue expanders are devices which are used to create enough skin to form suitable flap in restoration of great skin deficiencies which are not modified initially. The current study aimed at investigating the patients' satisfaction and the complications such as rupture, hematoma, wound infection, seroma, leakage, chronic pain, and expander expose of internal (implanted under the skin) and external (implanted outside) ports.
In a prospective quasiexperimental study conducted at Alzahra and Imam Musa al-Kadhim educational referral hospitals in Isfahan, two matched groups of patients each one contained 38 patients undergone, external and internal ports, were followed-up weekly until the removal of expander and the injection was done weekly through port. The frequency of complications and patients' satisfaction between two groups were compared.
The of age for patients in internal and external groups were 25.5 ± 8.7 and 24.7 ± 9, respectively (P = 0.71). There was significant difference between average of operation time of internal and external group (97.3 vs. 79.6; P < 0.001). The rate of complications such as infection, hematoma, skin necrosis, and expander expose between two groups was comparable, while significant difference was found between groups in terms of pain intensity in injection [4.92(1.2) vs. 1.53(0.69), P < 0.001]. There was no significant difference between groups in terms of symptom incidence and tissue expander insertion place as well as patients' satisfaction.
Although internal port has favorite appearance; however, some complications such as skin infection due to frequent injection, pain rate are higher than external port lead to its more acceptability by the patients.
组织扩张器是用于在修复严重皮肤缺损(最初未进行修复)时创造足够皮肤以形成合适皮瓣的装置。本研究旨在调查患者的满意度以及内部(皮下植入)和外部(体外植入)端口的并发症,如破裂、血肿、伤口感染、血清肿、渗漏、慢性疼痛和扩张器外露。
在伊斯法罕的阿尔扎赫拉医院和伊玛目穆萨·卡迪姆教育转诊医院进行的一项前瞻性半实验研究中,两组匹配的患者,每组38例,分别接受了外部和内部端口植入,每周进行随访直至扩张器取出,且每周通过端口进行注射。比较两组之间并发症的发生率和患者满意度。
内部组和外部组患者的年龄分别为25.5±8.7岁和24.7±9岁(P = 0.71)。内部组和外部组的平均手术时间存在显著差异(97.3对79.6;P < 0.001)。两组之间感染、血肿、皮肤坏死和扩张器外露等并发症的发生率相当,但在注射时的疼痛强度方面两组存在显著差异[4.92(1.2)对1.53(0.69),P < 0.001]。两组在症状发生率、组织扩张器植入部位以及患者满意度方面无显著差异。
尽管内部端口外观较好;然而,由于频繁注射导致的一些并发症,如皮肤感染、疼痛发生率高于外部端口,使得患者对外部端口的接受度更高。
