A New Wound Closure Achieving and Maintaining Device Using Serial Tightening of Loop Suture and its Clinical Applications in 15 Consecutive Patients for up to 102 Days

Role of Preoperative Skin Stretching in Single-Stage Wound Closure

Background  Mechanical skin stretching (SS) is now becoming one of the commonly sought after procedures for wound healing. This study was aimed to assess the efficacy of preoperative SS for the closure of large wounds and to evaluate various postoperative outcome parameters. Methodology  An observational study was conducted from December 2017 to May 2019 where a sample size of 30 patients was included with inclusion criteria being wounds of ≥5 cm width that require surgical management, presence of sufficient healthy skin edge of the wound/scar (at least one) for the stretching procedure, and age between 18 and 70 years. SS devices used were the top closure tension relief system. Postoperatively, various parameters were recorded to evaluate outcomes and complications. Results  Majority of wounds that is 16 (53.3%) were <50 cm ² , 9 (30%) were between 50 and 75 cm ² , and 5 (16.7%) were >75 cm ² . The mean duration of stretch was 2.3 ± 0.82 weeks. For 30 wounds treated with staged cycles of wound closure, there was a significant difference between every two visit points, i.e., 10%. The mean patient-reported patient and observer scar assessment scale score was 3.5 ± 0.93. Twenty-five cases (83.3%) had uneventful postoperative recovery. Twenty-seven patients (90%) reported an improved aesthetic outcome. Fourteen patients (46.7%) reported some improvement in function. Conclusion  The study concluded that the SS devices are the simple and effective method for the primary closure of large and challenging wounds and skin defects.

Efficacy and safety of external tissue expansion technique in the treatment of soft tissue defects: a systematic review and meta-analysis of outcomes and complication rates

Background

Currently, various external tissue expansion devices are becoming widely used. Considering the scarcity of relevant application standards, this systematic review was performed to explore the effectiveness and safety of external tissue expansion techniques for the reconstruction of soft tissue defects.

Method

A systematic review and meta-analysis on the efficacy and safety of external tissue expansion technique was conducted. A comprehensive search was performed in the following electronic databases: PubMed/Medline, Embase, Cochrane Library (Wiley Online Library), and Web of Science. Studies reporting patients with soft tissue defects under the treatment of external tissue expansion technique were included.

Results

A total of 66 studies with 22 different types of external tissue expansion devices met the inclusion criteria. We performed a descriptive analysis of different kinds of devices. A single-arm meta-analysis was performed to evaluate the efficacy and safety of the external tissue expansion technique for different aetiologies. The pooled mean wound healing time among patients with defects after fasciotomy was 10.548 days [95% confidence interval (CI) = 5.796–15.299]. The pooled median wound healing times of patients with defects after excisional surgery, trauma, chronic ulcers and abdominal defects were 11.218 days (95% CI = 6.183-16.253), 11.561 days (95% CI = 7.062-16.060), 15.956 days (95% CI = 11.916-19.996) and 12.853 days (95% CI=9.444-16.227), respectively. The pooled wound healing rates of patients with defects after fasciotomy, excisional surgery, trauma, chronic ulcers and abdominal defects were 93.8% (95% CI=87.1-98.2%), 97.2% (95%CI=92.2-99.7%), 97.0% (95%CI=91.2-99.8%), 99.5% (95%CI=97.6-100%), and 96.8% (95%CI=79.2-100%), respectively. We performed a subgroup analysis in patients with diabetic ulcers and open abdominal wounds. The pooled median wound healing time of patients with diabetic ulcers was 11.730 days (95% CI = 10.334-13.125). The pooled median wound healing time of patients with open abdomen defects was 48.810 days (95% CI = 35.557–62.063) and the pooled successful healing rate was 68.8% (95% CI = 45.9-88.1%). A total of 1686 patients were included, 265 (15.7%) of whom experienced complications. The most common complication was dehiscence (n = 53, 3.14%).

Conclusions

Our systematic review is the first to demonstrate the efficacy and safety of external tissue expansion in the management of soft tissue defects. However, we must interpret the meta-analysis results with caution considering the limitations of this review. Large-scale randomized controlled trials and long-term follow-up studies are still needed to confirm the effectiveness and evaluate the quality of healing.

Simple Skin-Stretching Device in Assisted Tension-Free Wound Closure

BACKGROUND

Numerous conventional wound reconstruction methods, such as wound undermining with direct suture, skin graft, and flap surgery, can be used to treat large wounds. The adequate undermining of the skin flaps of a wound is a commonly used technique for achieving the closure of large tension wounds; however, the use of tension to approximate and suture the skin flaps can cause ischemic marginal necrosis. The purpose of this study is to use elastic rubber bands to relieve the tension of direct wound closure for simultaneously minimizing the risks of wound dehiscence and wound edge ischemia that lead to necrosis.

MATERIALS AND METHODS

This retrospective study was conducted to evaluate our clinical experiences with 22 large wounds, which involved performing primary closures under a considerable amount of tension by using elastic rubber bands in a skin-stretching technique after a wide undermining procedure. Assessment of the results entailed complete wound healing and related complications.

RESULTS

All 22 wounds in our study showed fair to good results except for one. The mean success rate was approximately 95.45%.

CONCLUSIONS

The simple skin-stretching design enabled tension-free skin closure, which pulled the bilateral undermining skin flaps as bilateral fasciocutaneous advancement flaps. The skin-stretching technique was generally successful.

Lateral calcaneal artery adipofascial flap for reconstruction of the posterior heel of the foot

BACKGROUND

Soft tissue defects of the posterior heel of the foot present difficult reconstructive problems. This paper reports the authors' early experience of five patients treated with a lateral calcaneal artery adipofascial flap.

METHODS

Between 2003 and 2007, five patients (3 males and 2 females) with soft-tissue defects over the posterior heel underwent a reconstruction using a lateral calcaneal artery adipofascial flap and a full-thickness skin graft. The flap sizes ranged from 3.5 x 2.5 cm to 5.5 x 4.0 cm.

RESULTS

All five flaps survived completely with no subsequent breakdown of the grafted skin, even after regularly wearing normal shoes. The adipofascial flap donor sites were closed primarily in all patients.

CONCLUSIONS

Lateral calcaneal artery adipofascial flaps should be included in the surgical armamentarium to cover difficult wounds of the posterior heel of the foot. These flaps do not require the sacrifice of a major artery to the leg or foot, they are relatively thin with minimal morbidity at the donor site, and leave a simple linear scar over the lateral aspect of the foot.

Closing fasciotomy wounds using plastic bands: an alternative simple and cheap method

Fasciotomy incisions are essential to relieve pressure on the neurovascular structures in the limbs. However, closing such wounds often becomes a challenge to the surgeon. The aim of this study is to describe a simple and cheap method of closing these wounds. Plastic bands were used to gradually close fasciotomy wounds in five patients. All fasciotomy wounds in the five patients closed successfully within 4-12 days. Only two patients developed minimal complications in the form of minor wound infection and a hypertrophic scar. We conclude that the plastic band method used here is cheaper and simpler in comparison to similar techniques using the same device.

Tattoos: surgical removal

Surgical treatment of tattoos remains a useful tool for complete removal despite the availability of laser and other nonsurgical techniques. The procedures are in accordance with standard dermatosurgery used in aesthetic and oncologic therapies. Healing by primary intention or healing by secondary intention has its own indications. Skin defects can be closed by flaps, grafts, tissue extension, or tissue expansion.
