AbstractBackgroundVascularized lymph node transfer (VLNT) is an emerging surgical treatment for lymphedema. However, literature‐comparing outcomes of upper limb lymphedema (ULL) and lower limb lymphedema (LLL) is limited. Hence, the aim of this study is to compare the long‐term clinical outcomes on ULL versus LLL in patients treated with VLNT.MethodsA retrospective study retrieving data from patients with International Society of Lymphology (ISL) stages II–III who underwent different VLNTs from July 2010 to July 2016 in our institution was performed. Demographics preoperatively, and clinical data (limb circumference, infectious episodes, lymphoscintigraphic studies) preoperatively and postoperatively were recorded. Clinical outcomes by extremity were also analyzed.ResultsA total of 83 patients with lymphedema (ULL: n = 30, LLL: n = 53) were included. Mean follow‐up time was 32.8 months (range 24–49 months). Mean circumference reduction was higher in patients with ULL compared to with LLL (28.6 ± 8.6 vs. 22.3 ± 10.1, p < .001), and for patients with secondary lymphedema (24.8 ± 9.6, p < .001) than for patients with primary lymphedema (18.9 ± 14, p > .05). Infectious episodes per year preoperative and postoperative showed that LLL patients had higher reduction on infection rate compared with ULL patients (2.4 ± 1.1 vs. 1.9 ± 1.2, p < .001).ConclusionVLNT is a promising surgical treatment option for patients with lymphedema. This study suggests that VLNT may have a more beneficial outcome in patients with ULL and with secondary lymphedema.

BackgroundEnd‐stage lower extremity lymphedema (LEL) poses a particularly formidable challenge to surgeons as multiple pathological processes are at work. Because single modality treatment is often unsuccessful, we devised a comprehensive multimodal surgical treatment. The aim of this study is to share the technical considerations and examine the clinical outcomes of this combined approach.MethodsBetween 2013 and 2017, patients with International Society of Lymphology stage III, who underwent the combination treatment of Charles,’ Homan’s procedure with toe management and vascularized lymph node transfer (CHAHOVA), were included in this retrospective study. Outcomes evaluated were limb size, number of infectious episodes, compression garment usage, and rate of complications.ResultsA total of 68 patients were included. With a mean follow‐up of 29 months, the overall circumference reduction rate for the upper thigh and the rest of the extremity was 67.4% (48.2‐88.2%) and 98.1% (88‐100%), respectively. During the follow‐ups, 2 (2.9%) patients experienced episodes of cellulitis and the average number of yearly infections decreased from 4.2 to 1.2 episodes per person. All patients were able to discontinue compression therapy without recurrence of lymphedema. Nine (13.2%) patients reported minor complications.ConclusionThe combine CHAHOVA in a single‐stage procedure is an effective and safe approach in the end‐stage LEL.

BackgroundThe medial thigh is a well‐hidden area. The two most common flaps from this area are the transverse upper gracilis (TUG) and profunda artery perforator (PAP) flaps. Herein, we explored the applications of combined TUGPAP flap to reconstruct large and complex defects in different regions.MethodsBetween November 2015 and May 2017, 28 patients who underwent reconstruction and extensive soft tissue coverage with the TUGPAP flap for the breasts, head and neck, and pelvi‐perineal regions were included. The defects size ranged from 22 to 29 × 6–8 cm. All flaps were based on the two pedicles: the medial circumflex femoral artery for TUG flap and the profunda artery perforator for PAP flap. They were each anastomosed to a set of recipient vessels. A “Y”‐shaped interposition vein graft (YVG) was used if only one recipient artery was available.ResultsThe harvested skin paddle had dimensions ranged from 20 to 30 × 6–9 cm and all flaps survived completely. Postoperative complications included one case each of donor and recipient site seroma, and one case of wound dehiscence. They were all successfully managed conservatively. During an average follow‐up period of 12.7 months, one patient reported permanent paresthesia in the donor site and another developed hypertrophic scar. All patients were able to resume daily activity without major concerns.ConclusionThe combined TUGPAP flap is a safe, effective, and a good alternative to the common workhorse flaps as it offers the potential for a large skin paddle and decent soft tissue volume with low donor site morbidity in a well‐concealed area.

IntroductionComposite and large head and neck defects requiring extensive skin‐mucosa coverage are often reconstructed by combining flaps. Herein, we present a simple and reliable two‐stage fibula osteocutaneous (FOC) flap technique to improve the survival of a large skin paddle for oromandibular reconstructions.MethodsFrom October 2011 to September 2016, 47 patients with through‐and‐through oromandibular defects were reconstructed using FOC flaps with large skin paddles. To ensure optimum survival of skin paddles, temporary orocutaneous fistula were left in place and closed during the second stage operation via de‐epithelialization of the skin paddle and suturing of mucosa. Demographic data, operative details, and postoperative complications were recorded.ResultsThe skin paddle dimensions ranged from 20 to 31.5 cm in length and 12 to 17 cm in width with an average area of 430.4 cm2 (range 300–504). The average time between the two stages and hospital stay were 10 days and 14 days, respectively. Complications at the donor site included wound dehiscence (n = 3, 6.4%), partial skin graft loss (n = 3, 6.4%) and hematoma (n = 2, 4.3%). Recipient site complications included two (4.3%) early postoperative venous congestions that resolved after elevation and three (6.4%) partial skin flap necrosis (less than 5% surface area). All complications resolved with bedside conservative management. There was only one take‐back for evacuation of recipient site hematoma (2.1%) but no flap loss.ConclusionTwo‐staged large skin paddle FOC flaps can simplify reconstruction of extensive oromandibular defects by improving the reliability of the sizable skin paddle and negating the need for a second flap.

AbstractIntroductionReconstruction of abdominal wall defects with enterocutaneous fistulas (ECF) remains challenging. The purpose of this report is to describe a single‐stage approach using combined microscopic enterolysis, pedicle seromuscular bowel flaps, mesh, fasciocutaneous, and myocutaneous flaps.MethodsBetween 1990 and 2016 a retrospective review identified a total of 18 patients with an average age of 39 years (ranging 26–59 years). Thirteen cases were associated with trauma, four were complication of previous mesh repair, and one was after an aortic dissection. Average diameter of defect size was 22 cm (ranging 20–24 cm). Surgical technique involved enterolysis using microscope magnification, a pedicle seromuscular bowel flap to reinforce the bowel anastomosis, mesh, musculocutaneous, and fasciocutaneous flaps to reconstruct the abdominal wall.ResultsFifteen patients required rotational flaps with an average skin paddle area of 442.7 cm2 (ranging 440 cm2–260 cm2) and 10 patients required a serosal patch with an average length of 5 cm (ranging 4–6 cm). Complications included three wound dehiscence and one abdominal wall bulging. Flap survival was 100%. The majority of patients (12 out of 18) were able to resume normal activities, and the remaining (n = 6) were able to resume most activities. Functional outcome as assessed by 36‐Item Short Form Survey (SF‐36) physical function component questionnaire at 18–24 months follow up was 67.8% (ranging from 59 to 72%). Mean length of hospital stay was 2.2 weeks (ranging 1.4–2.7 weeks). Mean follow‐up was 24 months (ranging 22–26 months) with clinical examination.ConclusionMicroscopically assisted intra‐abdominal dissection with resection of diseased bowel, replacement with well‐vascularized tissue at the anastomosis site in, and reinforcement with mesh combined with pedicle musculocutaneous and fasciocutaneous flaps may be an alternative when other local reconstructive options have failed.

BackgroundReconstruction in a vessel‐depleted neck is challenging. The success rates can be markedly decreased because of unavailability of suitable recipient vessels. In order to obtain a reliable flow, recipient vessels away from the zone of fibrosis, radiation, or infection need to be explored. The aim of this report is to present our experience and clinical outcomes using the retrograde flow coming from the distal transverse cervical artery (TCA) as a source for arterial inflow for complex head and neck reconstruction in patients with a vessel‐depleted neck.MethodsBetween July 2010 and June 2016, nine patients with a vessel‐depleted neck underwent secondary head and neck reconstruction using the retrograde TCA as recipient vessel for microanastomosis. The mean age was 49.6 years (range, 36 to 68 years). All patients had previous bilateral neck dissections and all, except one, had also received radiotherapy. Indications included neck contracture release (n = 3), oral (n = 1), mandibular (n = 3) and pharyngoesophageal (n = 2) reconstruction necessitating free anterolateral thigh (n = 3) and medial sural artery (n = 1) perforator flaps, fibula (n = 3) and ileocolon (n = 2) flaps respectively.ResultsThere was 100% flap survival rate with no re‐exploration or any partial flap loss. One case of intra‐operative arterial vasospasm at the anastomotic suture line was managed intra‐operatively with vein graft interposition. There were no other complications or donor site morbidity during the follow‐up period.ConclusionsIn a vessel‐depleted neck, the reverse flow of the TCA may be a reliable option for complex secondary head and neck reconstruction in selected patients.

AbstractBackgroundVascularized lymph node (VLN) transfer for lymphedema treatment has shown promising results. Optimal donor and recipient sites remain a matter of debate. We describe the technique and outcomes of a laparoscopically harvested extended gastroepiploic VLN flap with two levels of inset.Patients and MethodsBetween 2014 and 2015, four‐patients with upper limb breast cancer‐related lymphedema and three‐patients with lower limb pelvic cancer‐related lymphedema who underwent VLN transfers were included. After harvest, the gastroepiploic VLN flap was divided into two halves that were separately inset at the level of elbow and wrist (upper limb) or knee and ankle (lower limb). The mean patient age was 53.1 years (range, 42–65 years).ResultsThe average flap size after division was 6.3 cm in length (range, 5–7 cm) and 3.4 cm in width (range, 3–4 cm). The mean pedicle length was 3.2 cm (range, 2.5–4 cm). All flaps survived completely. No donor or recepient site complication was noted. At a mean follow‐up of 9.7 months (range, 8–11 months), the mean circumference reduction rate was 43.7 ± 2.5% along the entire limb (P < 0.05). No episode of infection was noted postoperatively.ConclusionsDouble gastroepiploic VLN transfers to middle and distal limb are a safe approach with very promising results. This technique may be used to improve clinical outcomes by enhancing the lymphatic drainage of the entire affected limb in a uniform fashion. In addition, the laparoscopic harvest can provide decreased donor site morbidity with a faster recovery.

AbstractVascularized lymph node transfer has demonstrated promising results for the treatment of extremity lymphedema. In an attempt to find the ideal donor site, several vascularized lymph nodes have been described. Each has a common goal of decreasing morbidity and avoiding iatrogenic lymphedema while obtaining good clinical results. Herein, we present the preliminary clinical outcomes of an intra‐abdominal lymph node flap option based on the appendicular artery and vein used for the treatment of extremity lymphedema. A 62 year‐old woman with moderate lower extremity lymphedema, on chronic antibiotics because of recurrent infections and unsatisfactory outcomes after conservative treatment underwent a vascularized appendicular lymph node (VALN) transfer. At a follow‐up of 6 months, the reduction rate of the limb circumference was 17.4%, 15.1%, 12.0% and 9% above the knee, below the knee, above the ankle and foot respectively. In addition, no further episodes of infection or other complications were reported after VALN transfer. Postoperative lymphoscintigraphy demonstrated that the VALN flap was able to improve the lymphatic drainage of the affected limb. According to our findings, the use of VALN transfer minimizes donor‐site morbidity, avoids iatrogenic lymphedema and may provide a strong clearance of infection because of the strong immunologic properties of the appendiceal lymphatic tissue in selected patients. Despite these promising results, further research with larger number of patients and longer follow‐ up is needed.
