Surgical treatment and strategy in patients with pressure sores: A single-surgeon experience.

With aging, pressure ulcers become a common health problem causing significant morbidity and mortality for physically limited or bedridden elderly persons. Here, we present our strategy for such patients. Between August 2010 and March 2019, 117 patients were enrolled. Patient age, etiology, defect size and location, flap reconstruction, outcome, and follow-up period were reviewed. Of these patients, 64 were female and 53 were male, with an age range of 21 to 96 years (mean 75.6). The mean area of defect was 61.5 cm. The most common etiology was dementia (33.3%), and ulcers were most frequently caused by sacral pressure (70.3%). The commonest surgical treatment was a V-Y advancement flap (50%). The complication rate was 27.5%, including dehiscence and late recurrence. Negative pressure wound therapy could be used if the initial defect was large. V-Y advancement flap is the most frequent surgical treatment for sacral pressure ulcers because it is simple and available for most types of defect. Primary closure may be considered as the simplest method if the defective area is <16 cm. Intraoperative indocyanine green angiography can help avoid secondary flap revisions. Our protocol ensures a short surgery time, little bleeding, and a low complication rate.

Surgical treatment and strategy in patients with multiple pressure sores.

Pressure sores remain a common health problem, particularly among the physically limited or bedridden elderly, and can cause significant morbidity and mortality. This study aimed to present our surgical treatment and strategy for patients with multiple pressure sores. Between January 2010 and December 2016, 18 patients were enrolled. After adequate debridement, pressure sores were managed based on our treatment protocol. Patients' age, aetiology, defect size and location, flap reconstruction, outcome, and follow-up period were reviewed. A total of 10 men and 8 women (average age, 82.3 years) with a mean follow-up period of 28.3 months (6-72 months) were included. The mean defect area was 63.7 cm2 . The most common aetiology of the bedridden state was cerebrovascular accident (38.89%), and the most frequent sores were trochanteric pressure sores (53.57%). The average operative time and blood loss were 105.5 minutes and 100.8 mL, respectively. No haemodynamic variation or blood transfusion was noted during the surgery. The complication rate for each sore was 10.7%, including late recurrence. In conclusion, treating pressure ulcers requires careful patient education, intensive multidisciplinary optimisation, and meticulous wound care, and our treatment protocol ensures a shorter surgery time, less bleeding, and low complication rate.

Use of split-thickness plantar skin grafts in the management of leg and foot skin defects.

The basic principle of donor site selection is to take skin from areas that will heal with minimal scarring while balancing the needs of the recipient site. For skin loss from the lower legs and feet, the most common harvest site for split-thickness skin grafts is the anterior or posterior thigh; grafts from the plantar areas have been mostly used to cover the volar aspect of digits and palms. Between September 2015 and September 2017, 42 patients with areas of skin loss on the legs or feet were treated with plantar skin grafts because of their cosmetic benefits and the convenience of the surgical procedure and postoperative wound care. Our technique of harvesting a single layer of split-thickness skin graft (0.014 in. thick) from a non-weight-bearing area of the foot of the injured leg is simple and provided good functional and cosmetic outcomes at both the donor and recipient sites. All patients were very satisfied with the recovery progress and final results. Therefore, in the management of skin defects in the lower legs or feet that comprise less than 1.5% of the total body surface area, our surgical method is a reliable alternative to anterior or posterior thigh skin grafting.

A mesenteric primary peripheral Ewing's sarcoma/primitive neuroectodermal tumor with molecular cytogenetic analysis: Report of a rare case and review of literature.

Rare cases of Ewing's sarcoma/primitive neuroectodermal tumors (EWS/PNETs) arising from mesenteric tissue have been reported. This report describes an EWS/PNET in a 25-year-old woman who presented with abdominal pain lasting 3 days. Radiologic evaluation revealed a 9 cm × 6 cm homogeneous mass in the lower abdomen with homogeneous enhancement and invasion of the ileum. Surgical resection was completed during exploratory laparotomy. Immunohistochemically, the tumor cells revealed CD99, friend leukemia virus integration-1 and NKX2.2 (NK2 Homeobox 2, a protein coding gene) and subsequently showed EWSR1 rearrangement. The histological feature, immunohistochemical results and genetic fluorescence in situ hybridization analysis of this case were confirming the diagnosis of EWS/PNET. Adjuvant chemotherapy was suggested, but the patient was lost to follow-up.

Intraoperative Assessment of the Relationship Between Nipple Circulation and Incision Site in Nipple-Sparing Mastectomy With Implant Breast Reconstruction Using the SPY Imaging System.

INTRODUCTION: Nipple-sparing mastectomy (NSM) and immediate breast reconstruction with gel implants have grown in popularity because of superior aesthetic outcomes. One risk of this procedure is overexcision of the flap leading to inadequate circulation in the breast envelope. METHODS: We investigated 17 cases of NSM and gel implant breast reconstruction. Patients were divided into an infra-areolar incision group and a supra-areolar incision group. Nipple-areolar complex perfusion was evaluated using the SPY imaging system after NSM and gel implant breast reconstruction. We aimed to discover any relationships between the incision method and nipple-areolar complex (NAC) circulation in NSM and gel implant breast reconstruction. RESULTS: For successful breast surgery, awareness of the blood supply to the breast, especially the NAC, is very important. In our study, with the indocyanine green SPY imaging system, most ingress (arterial inflow) and egress (venous outflow) rates in the infra-areolar incision group were better than those in the supra-areolar incision group (P < 0.005). CONCLUSIONS: We have shown that an infra-areolar incision provides better blood flow following NSM and gel implant breast reconstruction. In our experience, in order to prevent the possible ischemia of NAC, we used the smaller gel implants, which is approximately 10 to 20 mL smaller than the original implant size measured by the sizer, if the egress rate of NAC is lower than 0.2. These findings have implications in the clinical setting as surgeons have a choice to provide a better outcome for patients.

Treatment of Thromboangiitis Obliterans Using Smoking Cessation and Far-infrared Therapy: A Case Study.

Thromboangiitis obliterans (Buerger's disease) is a rare, nonatherosclerotic segmental inflammatory vasculitis that commonly involves small- and medium-sized vessels. Ischemic tenderness impairs patient quality of life and places patients at high risk for amputation. The only definitive known treatment is smoking cessation. Far-infrared (FIR) therapy has shown promising effects on blood flow and healing, but its use in patients with Buerger's disease has not been reported. A 31-year-old man with a 15-pack-year history of smoking, no drug abuse, and no other significant medical history, trauma, or family history diagnosed with thromboangiitis obliterans presented for care at the authors' clinic. Claudication with severe tenderness of both legs and an ischemic ulcer over the right big toe were noted. After surgical debridement of the devitalized tissue, the patient received FIR therapy (5-25 µm, peak at 8.2 µm) applied 25 cm above the surface of the ischemic wound for 40 minutes, 3 times per week. The patient also tapered his smoking. The wound started to heal; granulation tissue was evident and, after 8 weeks, the right lower extremities gradually rewarmed from 24° C to 28° C as measured on the dorsal foot. His pain level decreased from 8 to 5. FIR therapy was continued until the patient stopped smoking (8 months). At the 10-month follow-up visit, the wound had healed completely and resting pain had improved. The results of this case study suggest additional research to explore the potential effects of FIR on patients with thromboangiitis obliterans is warranted.

Management of necrotising fasciitis secondary to abdominal liposuction using a combination of surgery, hyperbaric oxygen and negative pressure wound therapy in a patient with burn scars.

Liposuction is the one of the most frequently performed cosmetic operations and usually has an easy recovery, with a reportedly low overall complication rate. Here, we report the case of a 60-year-old woman with type II diabetes mellitus and a previous burn injury of the abdomen who underwent abdominal liposuction and subsequently developed necrotising fasciitis. Following radical debridement, systemic antibiotic administration, negative pressure wound therapy and hyperbaric oxygen therapy, the wound healed completely. This case demonstrates the success of the combination treatment and highlights the need for clinicians to be aware of the risk of serious complications in selected patients.

Is hyperbaric oxygen therapy indispensable for saving mutilated hand injuries?

Mutilated hand injuries are a profound challenge to the plastic surgeon, and such injuries often lead to limb loss and severe functional impairment. Hyperbaric oxygen therapy (HBOT) appears to counteract tissue hypoxia and stimulate acute wound healing. This study was performed to evaluate the efficacy of HBOT as an adjunctive therapy in patients with a mutilated hand injury. Between January 2006 and December 2014, 45 patients with a mutilated hand injury were enrolled. After reconstruction or revascularisation, patients underwent 120 minutes of HBOT with oxygen at 2·5 atmospheres absolute while breathing 100% oxygen. Outcomes such as amputee survival and surgery-related complications were recorded. The patients were 38 men and 7 women with average age of 37·2 years (range 18-62). The mean defect area was 131·5 cm2 (range 40-300). Most patients experienced a pure crush injury (53%). The average number of operations from the initial debridement to the first reconstruction was 3·8 (range 1-6). A total of 33 patients (73%) underwent replantation during the initial reconstruction. For flap coverage, most patients received a free flap using an anterolateral thigh flap (18 patients) or local flap using an abdomen/groin flap (nine patients). The average time from the first reconstruction or revascularisation to the first HBOT was 6·5 hours (range 2-12). The average number of HBOT sessions was 9·1 (range 6-14 sessions). The survival rate of the replanted fingers was 81%, and the survival rate of the palms was 100%. Most complications in the initial reconstruction involved partial loss of an avulsed flap, and most complications in the chronic stage (≥3 months) involved scar contracture. When combined with delicate microsurgery, early intervention using adjunctive HBOT was effective in preserving partially viable tissue and restoring hand function in patients with a mutilated hand injury.

Breast Reconstruction Using Pedicled Latissimus Dorsi Myocutaneous Flaps in Asian Patients With Small Breasts.

BACKGROUND: The use of implants is still the most common procedure for breast reconstruction because they are easy, less painful than tissue transplants, and do not need a donor site. However, it is challenging to find a suitable implant for patients with small breasts, and some women fear foreign bodies and possible complications or reoperations. Autologous breast reconstruction using the pedicled latissimus dorsi (LD) myocutaneous flap without an implant provides a good option for Asian women with small breasts. MATERIALS AND METHODS: Between June 1992 and December 2015, 31 patients underwent breast reconstruction with 33 LD flaps (29 unilateral and 2 bilateral). The skin paddle of the flap was designed with an oblique or transverse pattern depending on the mastectomy defect and the elasticity of skin. The thoracodorsal nerve was divided during flap harvesting to prevent a "twitching breast" postoperatively. Patients refused to have contralateral breast augmentation except for 2 with bilateral simultaneous augmentation after mastectomy bilaterally. Outcome measures were flap survival, shape and contour, symmetry of breast, complication of flap and donor site, patient satisfaction, and any local tumor recurrence or metastasis. RESULTS: The mean patient age was 46.7 years (range, 27-72), and the mean body mass index was 22.5 kg/m (range, 18.6-30). The mean size of the harvested skin paddle was 11.9 × 5.0 cm (range, 10 × 3 cm to 15 × 9 cm). Mean operative times were 200.8 minutes (range, 112-230 minutes) and 305 minutes (range, 300-310 minutes) for unilateral and bilateral reconstructions, respectively. Pathology reports showed a negative safety margin in all cases. Most cases were of invasive duct carcinoma (58%). All LD flaps survived, and the wounds healed satisfactorily over a mean follow-up of 49.9 months (range, 3-161 months). Donor sites were closed primarily with a hidden linear scar under the dorsal bra strap. Donor site morbidities were mainly seromas (15%), which were treated conservatively in most patients. CONCLUSIONS: The LD flap produced good autologous tissue for reconstruction, and no implants were needed for Asian women with small breasts. The reconstructed breasts showed good shape, contour, and symmetry. The results of donor site were acceptable and no significant functional loss. There were no major complications, and patient satisfaction was high.

Postmastectomy Breast Reconstruction Combined With Contralateral Breast Augmentation for Taiwanese Women With Small Breasts.

BACKGROUND: Although autogenous tissue-based breast reconstruction has been widely used in the past decade, implant-based breast reconstruction is more often used in Taiwan because Asian women are generally slender with small breasts. For patients with very small breasts, it is hard to achieve the goal of reconstructing a similar breast to the contralateral one, even with the smallest size implant available commercially. Therefore, these patients need not only breast reconstruction but also contralateral breast augmentation. Here we report the surgical outcomes and cosmetic results of breast reconstruction using cohesive gel implants combined with simultaneous contralateral breast augmentation. MATERIALS AND METHODS: A retrospective chart review was conducted to identify all patients with AA-sized to B-sized breast cups undergoing expander-implant reconstruction combined with contralateral breast augmentation between 2002 and 2015. Thirty patients were included. For each patient, patient profile (age, body mass index, and initial breast size), type and stage of breast cancer, surgical information (including implant sizes and the type of reconstruction and augmentation), and postoperative subjective pain scales were recorded. Outcomes were analyzed by identifying complications, the need for surgical revision, the presence of local or distant metastases, and patient satisfaction ratings. RESULTS: At a mean 2.3-year follow-up (range, 4 months to 12 years), problems occurred in 7 of the 30 patients, with 9 complications in 8 reconstructed breasts and in 1 augmented breast. Complications were mostly capsule contracture. Aesthetic satisfaction was rated as "excellent" or "good" by most of the patients, and only 1 commented "poor" on both overall and reconstructed results because of postoperative radiotherapy-associated skin necrosis. The total mean subjective pain scale was 1.9/10; a higher mean pain scale of 3.08 was noted in those patients undergoing augmentation with no extra incision. CONCLUSIONS: This is the first report of implant-based breast reconstruction with simultaneous contralateral augmentation in Taiwan, showing its efficacy, safety, and good cosmetic outcomes with relatively low complication and revision rates.

Pedicled medial sural perforator flap for the reconstruction of knee defects.

Soft tissue defects exposing the patellar tendon or bone are common in patients who have experienced trauma or implant infection. The purpose of this article is to present our experience of six patients who underwent reconstruction of soft tissue defects of the knee using a pedicled medial sural perforator flap. Between November 2013 and November 2015, six patients who presented with a soft tissue defect overlying the knee were admitted to our hospital. After adequate debridement or wide excision of the tumour, these patients underwent pedicled medial sural perforator flap placement to resurface the complex soft tissue defects and to provide a gliding surface for the exposed patellar tendon. The patients' age, comorbidity, aetiology, defect size and location, flap size, perforator numbers and lengths, outcome and follow-up period were reviewed. The six medial sural perforator flaps survived completely, and the wounds healed satisfactorily over a mean follow-up of 21·5 months (range, 6-51 months). Donor sites were closed primarily or covered with a split-thickness skin graft. The medial sural perforator flap is a reliable flap for coverage of defects overlying the knee. The thin and pliable flap, long pedicle length and less donor site mobility benefit patients. Thus, the medial sural perforator flap may be a valuable alternative for defect reconstructions overlying the knee, which produces satisfactory results both functionally and cosmetically.

Adjunctive hyperbaric oxygen therapy in severe burns: Experience in Taiwan Formosa Water Park dust explosion disaster.

BACKGROUND: Despite major advances in therapeutic strategies for the management of patients with severe burns, significant morbidity and mortality is observed. Hyperbaric oxygen therapy (HBOT) increases the supply of oxygen to burn areas. The aim of this study was to determine whether HBOT is effective in the treatment of major thermal burns. METHODS: On June 27, 2015 in New Taipei, Taiwan, a mass casualty disaster occurred as fire erupted over a large crowd, injuring 499 people. Fifty-three victims (20 women and 33 men) were admitted to Tri-Service General Hospital. Thirty-eight patients underwent adjunctive HBOT (HBOT group), and 15 patients received routine burn therapy (control group). Serum procalcitonin (PCT) level, a sepsis biomarker, was measured until it reached normal levels (<0.5µg/L). The records of all patients from June 2015 to March 2016 were analyzed retrospectively. Outcome measures that were compared between the groups included the use of tracheostomy and hemodialysis, total body surface area (TBSA) and the number of skin graft operations, length of hospital stay, infection status, and mortality. RESULTS: The mean age of the patients was 22.4 years, and the mean TBSA was 43%. All the patients survived and were discharged without requiring limb amputation or being permanently disabled. Patient characteristics did not differ significantly between the groups. PCT levels returned to normal significantly faster (p=0.007) in the HBOT group. CONCLUSION: Multidisciplinary burn care combined with adjunctive HBOT improves sepsis control compared with standard treatment without HBOT. Prospective studies are required to define the role of HBOT in extensive burns.

Hyperbaric Oxygen Therapy for the Adjunctive Treatment of Pyoderma Gangrenosum: A Case Report.

Pyoderma gangrenosum (PG) is a neutrophilic dermatosis of unknown etiology characterized by an ulcerative skin condition and confirmed through a diagnosis of exclusion. Management usually consists of systemic drug therapy, such as corticosteroids, sulfones, or immunosuppressants, either alone or in combination. Long-term use of these medications often has untold side effects. Hyperbaric oxygen therapy (HBOT) has been shown effective in the treatment of PG, reducing pain and tempering the need for medication. A case is presented of a 54-year-old woman with diabetes, hypertension, and a peptic ulcer who presented with painful, purulent ulcers on her buttocks, hands, and lower extremities of 2 weeks' duration. She was ultimately diagnosed with PG and provided 20 mg/day of oral prednisone for 1 week, tapered to 10 mg/day in the next week and then stopped. In addition, she received 12 sessions of HBOT - she breathed in 100% oxygen under 2.5 atmospheres absolute pressure for 90 minutes over 2 weeks. Her wounds healed without scarring. This excellent outcome including good wound healing, decreased pain, and reduced doses of systemic corticosteroids warrants additional study of the adjunctive use of HBOT for PG.

Treatment of Sternal Wound Infection Using a Free Myocutaneous Flap.

Deep sternal wound infections are potentially life-threatening complications after cardiac operations because they can spread into the mediastinum and cause postoperative morbidity and mortality. We present a 65-year-old man with a history of coronary artery bypass grafting. A large sternal defect was left after debridement. After brief vacuum-assisted closure (VAC), a free myocutaneous flap of the anterolateral thigh (ALT) was used to fill the dead space. At the 9-month follow-up, the wound had healed completely without tissue loss or complications, and the patient returned to normal life. This was a successful treatment of a deep sternal wound with free flap coverage.
