Optimizing Outcomes in Pharyngoesophageal Reconstruction and Neck Resurfacing: 10-Year Experience of 294 Cases.

BACKGROUND: Pharyngoesophageal reconstruction is a complex endeavor that poses many challenges. This 10-year series examines factors impacting the need for neck skin resurfacing and evaluates the impact of reconstructive modalities on outcomes. METHODS: A review identified 294 patients who underwent pharyngoesophageal reconstruction from 2002 to 2012. Patients were divided based on neck skin resurfacing requirements. Patients undergoing neck resurfacing were further subdivided into reconstructive technique, including a second skin paddle or muscle component from the same free flap pedicle, a local flap, or a second free flap. All groups were compared by comorbidities, complications, and functional outcomes. RESULTS: Of 294 patients, 179 (60.9 percent) required neck skin resurfacing. In the resurfaced group, there were 90 circumferential defects (50.3 percent) and 89 partial defects (49.7 percent). In the resurfaced group, 110 (61.4 percent) underwent reconstruction with a second skin paddle from the same free flap pedicle, 21 (11.7 percent) underwent reconstruction with a muscle component from the same pedicle, and 25 (13.9 percent) received a pectoralis major flap. There were five external paddle flap losses in the resurfaced group (2.8 percent) and no internal flap losses. Overall complications were similar among groups. The resurfaced group had a lower pharyngocutaneous fistula rate (4.5 percent) compared with the primary closure group (11.3 percent) (p = 0.026). Prior neck surgery and radiation therapy were strong predictors of neck skin resurfacing (p < 0.001). CONCLUSIONS: Neck resurfacing is often required in salvage pharyngoesophageal reconstruction. Providing additional vascularized tissue over the neoconduit is predictive of lower pharyngocutaneous fistula rates. An algorithmic approach to neck resurfacing is presented.

Prospective study on the treatment of lower-extremity chronic venous and mixed ulcers using tissue-engineered skin substitute made by the self-assembly approach.

BACKGROUND: Despite present optimal standard treatment of lower-extremity ulceration, a high incidence of recurrence and treatment failure is observed. The objective of this project was to evaluate the effect of a self-assembled skin substitute (SASS) made by tissue engineering as a temporary cutaneous dressing in the treatment of hard-to-heal chronic ulcers. PATIENTS AND METHODS: The prospective uncontrolled case study includes patients suffering from venous or mixed ulcers lasting more than 6 months and unresponsive to compression therapy, with an Ankle Brachial Index greater than 0.5. Compression therapy was combined with the weekly application of SASS, produced from the patient's own skin cells, until healing. A weekly follow-up recorded wound size, skin aspect, pain, drainage, and percentage of wound healing. Photographs were also taken to assess ulcer evolution. RESULTS: Fourteen ulcers present on 5 patients were treated. A mean of 6.7 SASS depositions by ulcer was required for healing. Two ulcers developed a minor wound infection, which was treated with oral antibiotics; another 2 ulcers recurred, and 1 healed with a second course of treatment, whereas 1 ulcer had a small recurrence treated with local wound care. CONCLUSION: The authors' study suggests that the SASS used as a biological dressing is a promising treatment for hard-to-heal chronic venous and mixed ulcers that are unresponsive to compression therapy.

A review of 105 subscapular-based flaps harvested using a new dorsal decubitus position: how far can we go?

OBJECTIVE: Interest in flaps based on the subscapular vascular system has decreased because of the need for intraoperative patient repositioning and the inability to employ a simultaneous 2-team approach. The aims of this study are to review our experience using dorsal decubitus patient positioning for subscapular-based flap harvest and to demonstrate the effectiveness and safety of this approach. METHODS: A retrospective review of all subscapular-based flap cases performed by the senior author at 2 hospital centers from 1995 to 2010 was conducted. Variables studied included indications for reconstruction, flap characteristics, and postoperative complications. A longitudinal roll placed between the scapulae as well as an optional perpendicularly placed shoulder roll are used to achieve dorsal decubitus patient positioning. RESULTS: One hundred five flaps were performed during the study period, and dorsal decubitus positioning was used in all cases. Eighty-four flaps were free and 21 were pedicled. Indications for reconstruction included cancer resection (n = 58), trauma (n = 32), infection (n = 9), and others (n = 6). A simultaneous 2-team approach was carried out in 70 cases. Major complications included 9 cases of arterial or venous thrombosis/insufficiency, 2 of which resulted in total flap failure. Intraoperative conversion to lateral decubitus positioning was never required. CONCLUSIONS: Dorsal decubitus harvesting for subscapular-based flaps is a practical and effective technique that enables a simultaneous 2-team approach in complex reconstructive cases. Previous limitations of these highly versatile flaps, such as the need for intraoperative patient repositioning, can thus be avoided. This approach is employed for all subscapular-based flap reconstructions performed by the senior author.

A new dorsal decubitus position for raising subscapular-based flaps.

Flaps based on the subscapular vascular system are reliable and versatile tools that provide excellent coverage for a wide range of tissue deficits. Raising these flaps in the described dorsal decubitus position permits two surgical teams to work simultaneously while obviating the need for intra-operative position changes. In cases where a subscapular-based flap is deemed the most suitable option for reconstruction, the dorsal decubitus technique eliminates many of the limitations associated with the traditional lateral decubitus approach without compromising the range of tissue obtainable.

Dorsal decubitus positioning: a novel method to harvest the latissimus dorsi flap for massive upper extremity defect reconstruction.

The latissimus dorsi, whether taken as a muscle or with a skin paddle, is one of the most useful flaps in the reconstructive surgeon's arsenal. With its predictable type V vascular pedicle, this broad muscle can be elevated on its dominant thoracodorsal pedicle or used in a reverse manner on its secondary thoracic and lumbar perforators. Traditionally harvested in a lateral decubitus position, over the last 10 years we have chosen to elevate this muscle in a dorsal decubitus position, enabling 2 surgical teams to operate simultaneously. With only one cushion placed along the vertebral column between the scapulas, each element of the subscapular system, including scapular bone, can be used to reconstruct complex upper limb defects. A vertical incision in front of the anterior axillary line is performed to identify the anterior border of the muscle, followed by a dissection in the submuscular plane to reveal the thoracodorsal pedicle and its branches. When a more complex chimeric flap is required, scapular bone, serratus muscle, and scapular or parascapular fasciocutaneous flaps are all available. To achieve the longest length possible, the pedicle can be isolated from the axillary vessels. The most common complications are related to donor site, with seroma and delayed wound healing being the most prevalent. Complaints of shoulder pain and functional disability were rare and mostly encountered in the first 2 weeks postoperatively.
