RESUMEN
INTRODUCTION: Some surgeons have raised concerns regarding the sympathectomy-like effect of epidural anesthesia during lower limb microvascular reconstruction. The combined spinal-epidural (CSE) anesthetic technique incorporates several benefits of spinal and epidural techniques in a single approach. The aim of this study was to analyze the postoperative outcomes of patients undergoing soft-tissue reconstruction of the lower limb by implementing the CSE anesthesia approach. METHODS: We reviewed medical records from patients who underwent lower limb reconstructive procedures under CSE anesthesia with free tissue transfer from January 2017 to December 2020. We evaluated the postoperative outcomes. RESULTS: Thirty-eight patients underwent microvascular reconstructive procedures of the lower extremity over the study period. The average age and BMI were 38.4-year and 28 kg/m2. All patients only had one postoperative rescue dose with epidural anesthesia. The most common type of flap used was the anterolateral thigh flap (53%). The average splinting time and length of stay (LoS) were 8.4 days and 18.4 days, respectively. Donor-site complications included wound dehiscence (3%) and surgical site infection (3%). Recipient-site complications included partial flap loss (8%) and total flap loss (10%). No pro re nata morphine analgesia was used. Tramadol and/or ketoprofen were administered for postoperative analgesia. The average time to start physiotherapy and to resume daily activities were 10 days and 29 days, respectively. CONCLUSIONS: The CSE anesthesia for microvascular reconstruction of the lower limb demonstrated a similar success rate compared to historical records. CSE provided adequate pain management and none of the patients required postoperative monitoring in the ICU.

BACKGROUND: Multiple surgical alternatives are available to treat breast cancer-related lymphedema (BCRL) providing a variable spectrum of outcomes. This study aimed to present the breast cancer-related lymphedema multidisciplinary approach (B-LYMA) to systematically treat BCRL. METHODS: Seventy-eight patients presenting with BCRL between 2017 and 2021 were included. The average age and BMI were 49.4 ± 7.8 years and 28.1 ± 3.5 kg/m2 , respectively. Forty patients had lymphedema ISL stage II (51.3%) and 38 had stage III (48.7%). The mean follow-up was 26.4 months. Treatment was selected according to the B-LYMA algorithm, which aims to combine physiologic and excisional procedures according to the preoperative evaluation of patients. All patients had pre- and postoperative complex decongestive therapy (CDT). RESULTS: Stage II patients were treated with lymphaticovenous anastomosis (LVA) (n = 18), vascularized lymph node transfer (VLNT) (n = 12), and combined DIEP flap and VLNT (n = 10). Stage III patients underwent combined suction-assisted lipectomy (SAL) and LVA (n = 36) or combined SAL and VLNT (n = 2). Circumferential reduction rates (CRR) were comparable between patients treated with LVA (56.5 ± 8.4%), VLNT (54.4 ± 10.2%), and combined VLNT-DIEP flap (56.5 ± 3.9%) (p > .05). In comparison to LVA, VLNT, and combined VLNT-DIEP flap, combined SAL-LVA exhibited higher CRRs (85 ± 10.5%, p < .001). The CRR for combined SAL-VLNT was 75 ± 8.5%. One VLNT failed and minor complications occurred in the combined DIEP-VLNT group. CONCLUSION: The B-LYMA protocol directs the treatment of BCRL according to the lymphatic system's condition. In advanced stages where a single physiologic procedure is not sufficient, additional excisional surgery is implemented. Preoperative and postoperative CDT is mandatory to improve the outcomes.

BACKGROUND: Supermicrosurgery is a technique that allows microsurgeons to accomplish dissections and anastomoses of vessels and nerve fascicles with diameters of ≤0.8 mm. Considering the potential benefits of this technique and limited literature synthesizing the outcomes of supermicrosurgery, the aim of this study was to summarize the available evidence of reconstructive supermicrosurgery and to estimate the success rate. METHODS: We conducted a comprehensive search across PubMed, Scopus, Embase, and Web of Science. We included patient-based studies reporting on procedures for soft-tissue reconstruction with free flaps specifying the use of supermicrosurgery. We excluded studies reporting on lymphatic surgery, solely peripheral nerve surgery, and tissue replantation. Our primary endpoint was to calculate the flap success rate. Pooled estimates were calculated using a random-effects meta-analytic model. RESULTS: Forty-seven studies reporting outcomes of 698 flaps were included for qualitative synthesis. Overall, 15.75% of flaps were used for head and neck, 4.4% for breast and trunk, 9.3% for upper limb, and 69.2% for lower limb reconstruction. The most used flap was the superficial circumflex iliac artery perforator flap (41.5%). The overall flap success rate was 96.6% (95%CI 95.2%-98.1%). The cumulative rate of partial flap loss was 3.84% (95%CI 1.8%-5.9%). The overall vascular complication rate resulting in complete or partial flap loss was 5.93% (95%CI 3.5%-8.3%). CONCLUSIONS: Supermicrosurgery displays a high success rate. Further studies are necessary to explore the true potential of supermicrosurgery. This technique reformulates the boundaries of reconstructive surgery due to its extensive application.

BACKGROUND: Retromolar trigone (RMT) cancer is a rare malignancy, which develops in a narrow area of the oral cavity. Surgical intervention requires wide excision and appropriate reconstruction usually with a free tissue transfer. Little has been published regarding the ideal microvascular reconstruction, mainly focusing on radial forearm and anterolateral thigh free flap. The medial sural artery perforator flap (MSAP) is not new for head and neck reconstruction but its use for RMT reconstruction has not been previously explored. The purpose of the study is to present a multicentric case series investigating the reliability of MSAP flap for RMT reconstruction. METHODS: The study is designed as a retrospective case series. All patients diagnosed with RMT cancer and undergone surgical resection and immediate reconstruction with a MSAP flap between February 2016 and March 2020 were identified. Patients' demographics and surgical details were collected. Functional results were evaluated using the Head and Neck Module of the European Organization for Research and Treatment of Cancer at 12 months of follow-up. A total of 34 patients with a mean age of 58 years were included in the study. An average defect size of 31.5 cm2 was observed after RMT tumor resection. RESULTS: The MSAP flaps' average dimensions were 11 ± 3.1 cm in length and 4.7 ± 1.6 cm in width with a mean thickness of 1.4 ± 0.8 cm. No flap complications were observed in 28 cases; four patients developed an orocutaneous fistula. One patient needed surgical revision for venous congestion while only one case of flap failure was observed. At 12 months of follow-up, 87% of the patient cohort had normal, understandable speech. No patient experienced complete loss of swallowing. Results of the H&N35 module showed a significative postoperative improvement in mouth soreness, mouth opening and social (p < .05*). No patient complained difficulty in motility at the donor site. CONCLUSIONS: The MSAP flap appears to be appropriate for RMT reconstruction and could be considered the workhorse for small to medium size defect of RTM region. It has a long pedicle of matching caliber and provides adequate tissue volume with minimal donor site morbidity.

Previous studies have evaluated the effectiveness of bacterial nanocellulose (BNC) for the treatment of thermal injuries, but the synergic effect of platelet-rich plasma (PRP) with BNC-based dressing for burns still requires further investigation. Herein, we evaluated the effectiveness of BNC dressings in the management of facial burns using PRP. Patients with second-degree facial burns were treated with BNC-based wound dressings after debridement. The burn's depth and epithelialization were evaluated by clinical assessment. Besides using the dressings, we injected PRP subcutaneously into the left-hemifacial burns. The right hemiface was only treated with the dressings. Scar quality was assessed using the Patient and Observer Scar Assessment Scale (POSAS). Eight patients were included with superficial second-degree burns in 75% of the cases and deep second-degree burns in 25%. Overall, dressings were placed 3.25 days after the initial insult. None of the patients presented with complications after dressing placement. Dressing changes were not required, and no further surgical management was necessary. The mean time for epithelialization was 11.4 days. During subgroup analysis, we did not find a significant difference in the epithelialization time when comparing BNC-based dressings (11.8 days) to BNC-based dressings + PRP (11 days, p = 0.429). The mean POSAS scores from a patient (17 vs. 12.3, p = 0.242) and surgeon (13.5 vs. 11.3, p = 0.26) standpoint were not significantly different using BNC-based dressings versus BNC-based dressings + PRP. Nanocellulose-based dressings are effective to treat second-degree facial burns. It enhances reepithelialization with optimal esthetic outcomes with or without PRP.

Tumoral involvement of the carotid artery may require en-bloc resection in order to achieve a better regional control. Among the carotid reconstruction methods at disposal, autologous tissues appear to be more reliable in cases with high risk of infection and poor tissue healing like in radiated necks. We describe a case of a 55 year old man, who suffered from recurrent squamous cell carcinoma in the neck region, invading the common carotid artery. After en-bloc resection of the tumor together with skin, internal jugular vein, vagus nerve and common carotid artery, carotid reconstruction was performed with a flow-through chimeric flap based on superficial femoral vessels (15 cm). After resection of the tumor, the flap was used to replace the soft tissue defect (23 × 12 cm). Anteromedial thigh skin paddle (8 × 5 cm) and sartorius muscle (12 × 3 cm) were included in the flap. The superficial femoral vessels were reconstructed with 8-mm ringed polytetrafluoroethylene graft interposition. Thanks to an accurate surgical planning and a 2-team approach, the ischemia time of the leg was 42 min and there were no limb ischemia nor pathologic neurological signs after surgery. During the 12-month follow up, no other complication was registered. In our experience, microsurgical carotid reconstruction represents a reliable option with important advantages such as resistance to infection, optimal size matching, and good tissue healing between the irradiated carotid stump and the vascular graft.

Breast cancer-related lymphedema following axillary lymph node dissection (ALND) has been documented in 6%-55% of patients, mostly occurring within the next 3 years after radiation or surgery. We present a case of a 53-year-old patient with hormone positive, stage IB, left breast invasive ductal carcinoma treated with immediate lymphatic and microvascular breast reconstruction (MBR) using vascularized lymph node transfer (VLNT) for lymphedema prevention. A deep inferior epigastric perforator (DIEP) flap (18.3 × 11.2-cm) and simultaneous prophylactic gastroepiploic-VLNT (7 × 3-cm), orthotopically inset in the axilla, were used for reconstruction following mastectomy and radical ALND. The procedure was uneventful. The patient did not display increased postoperative arm circumferences. ICG lymphography did not show any changes at 2- and 3-years after surgery. Preventive lymphatic reconstruction with GE-VLNT and immediate MBR using the DIEP flap offers a new possibility for the primary prevention of lymphedema and simultaneous immediate autologous breast reconstruction without the risk of iatrogenic lymphedema. Further studies will be directed to unveil the external validity of these findings and the risk reduction rate of this approach.

BACKGROUND: The profunda artery perforator (PAP) flap has been reported in several types of reconstructions. This report aims to evaluate the usefulness and the clinical outcome of patients who underwent the PAP free flap for lower limb reconstruction. METHODS: Between February 2018 and February 2020, nine patients with injury at lower third of the leg, foot dorsum or foot plant (eight acute injuries and one chronic ulcer) were selected. Mean wound size was 12.5 × 6.3 cm (9 × 5-14.5 × 6.5). Inclusion criteria consisted in patient's request to hide the donor site scar and the absence of previous traumas or surgery in the donor site. Patients considered unable to bear prolonged surgery were excluded. Patients underwent preoperative CT angiography and peri-operative Doopler, for perforator selection. All flaps were designed with pinch test, in elliptical shape. Microvascular anastomosis was performed to the tibialis anterior/posterior or medial plantar vessels. Outcomes were evaluated in terms of wound coverage success and patient's quality of life through Lower Extremity Functional Scale (LEFS) questionnaire. RESULTS: The mean size of the harvested skin paddle was 13.5 × 7.4 cm (9 × 6-15 × 8) and mean pedicle length was 8.5 cm. Mean flap harvest time was 43.5 min (35-55). Flap survival rate was 100%, with one re-exploration with minimal partial flap loss. Mean follow-up was 13.5 months . Reconstructive results were successful in wound coverage and function. All patients reported satisfaction with their result by LEFS questionnaire (score:64.7). CONCLUSION: With proper patient selection, there was 100% flap survival rate with no major complication. According to our data, the PAP free flap could be a valuable option for lower extremity reconstruction.

BACKGROUND: Various studies have discussed the benefits of applying three-dimensional (3D) techniques, specifically its advantages with respect to ergonomics, feasibility, and the rate of learning achievable in microsurgery training. However, no study has been conducted that compares the operator experience of using two-dimensional (2D) and 3D systems in microsurgical training. The aim of this study is to compare 2D- and 3D-assisted microsurgical training in novices based on anastomosis of chicken femoral arteries. METHODS: The participants were grouped by previous microsurgical experience. Group A includes novice participants. Group B includes 2D-experienced participants. Group C includes both participants in groups A and B. A questionnaire composed of 10 parameters in the field of image quality, dexterity, ergonomic, and feasibility will be filled out after each participant finished their anastomoses by the 2D and 3D systems. RESULTS: The results demonstrated 3D system was scored better on "field of view" (p = 0.004), "less tremor" (p = 0.005), "neck/upper back comfort" (p = 0.043), "lower back comfort" (p = 0.015), "technical feasibility" (p = 0.020), and "educational feasibility" (p = 0.004) in group A (N = 12). In group B (N = 9), 3D system was scored better on "field of view" (p = 0.041) but worse on "image resolution" (p = 0.031). CONCLUSION: With the 3D visualization system for microsurgical anastomosis of chicken femoral model, there are significant improvements in the field of view, stability, ergonomics, and educational value compared with 2D system among all participants. Accordingly, 3D-assisted microsurgery training can be a novel and potential popular training method.

BACKGROUND: Abdominal wall vascularized composite allotransplantation (AW-VCA) is a novel reconstructive technique used for large abdominal wall defects in combination with intestinal transplantation (ITx) or multivisceral abdominal transplantation (MVTx). Since the introduction of this procedure, several studies have been published reporting their experience. This study aims to present a scoping review looking at all available evidence-based medicine information to understand the most current surgical techniques and clinical outcomes. METHODS: This scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) extension for scoping reviews checklist. A comprehensive research strategy of several databases was conducted. RESULTS: A total of 31 studies were included in this review, which comprised animal, cadaveric, and human studies. In human studies, four surgical techniques with high flap survival rates and low complication rates were found. In cadaveric studies, it was shown that the use of iliofemoral cuff-based flaps provided adequate tissue perfusion to the abdominal wall graft. Also, the use of thoracolumbar nerves have been described to provide functionality to the AW-VCA and prevent long-term muscle atrophy. CONCLUSION: AW-VCA is a safe and efficient alternative for patients with large and complex abdominal wall defects. The future holds a promising evolution of a functional AW-VCA, though surgeons must face and overcome the challenge of distorted anatomy frequently present in this population. Forthcoming studies with a better level of evidence are required to evaluate functionality and differences between surgical techniques.

BACKGROUND: Uterine transplantation (UTx) is acknowledged to be on the second (2A) of five steps of development in accordance with the staging system for the evaluation of surgical innovations. Accordingly, we aimed to systematically review the available evidence of the surgical techniques and outcomes of UTx in terms of graft survival. METHODS: A comprehensive search was conducted across PubMed Medline, Cochrane-EBMR, Scopus, Web of Science, and CENTRAL through November 2020. RESULTS: Forty studies, reporting 64 recipients and 64 donors, satisfied inclusion criteria. The surgical time and the estimated blood loss were 515 minutes and 679 mL for graft procurement via laparotomy, 210 minutes and 100 mL for laparoscopic-assisted graft harvest, and 660 minutes and 173 mL for robotic-assisted procedures, respectively. Urinary tract infections (n = 8) and injury to the urinary system (n = 6) were the most common donor complications. Using the donor's internal iliac system, two arterial anastomoses were performed in all cases. Venous outflow was accomplished through the uterine veins (UVs) in 13 cases, a combination of the UVs and the ovarian/uteroovarian veins (OVs/UOVs) in 36 cases, and solely through the OVs/UOVs in 13 cases. Ischemia time was 161 and 258 minutes when using living donors (LD) and deceased donors (DD), respectively. Forty-eight uteri were successfully transplanted or fulfilled the purpose of transplantation, 41 from LDs and 7 from DDs. Twenty-five and four live childbirths from LDs and DDs have been reported, respectively. CONCLUSION: UTx is still experimental. Further series are required to recommend specific surgical techniques that best yield a successful transplant and reduce complications for donors and recipients.

BACKGROUND: Studies reporting on the deep circumflex iliac artery (DCIA) free flap are restricted to a limited number of patients and areas of application. The aim of this review was to assess the reliability and versatility of the DCIA free flap during reconstruction. METHODS: A comprehensive review was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines using PubMed, Web of Science, Cochrane CENTRAL, and SCOPUS. A critical analysis of pooled data was performed to assess outcomes employing the DCIA free flap. RESULTS: A total of 445 DCIA free flaps were included. The main recipient sites were head and neck (72.35%), lower extremity (20.67%), and upper extremity (6.74%). The main indications for reconstruction were tumor resection (73.8%) and trauma (17.43%). Fifty non-DCIA flaps were required to finalize the reconstruction of several defects. The pooled flap failure rate using the DCIA free flap was 4% (95% confidence interval: 1-8%). No significant heterogeneity was present across studies (Q statistic 22.12, p = 0.14; I 2 = 27.68%, p = 0.139). Complication rates for head and neck and limb reconstruction were 57.37 and 40.16%, respectively. The average length and surface area of bone flaps were 7.79 cm and 22.8 cm2, respectively. The area of the skin paddles was 117 cm2. CONCLUSION: The DCIA free flap has shown to be a versatile reconstructive alternative for head and neck and short-medium size limb defects. However, the complexity of functions, the recipient site location, and a potential large defect can detract from the use of the DCIA free flap as an initial reconstructive option for head and neck and extensive limb defects.

Background Several studies have proven prophylactic lymphovenous anastomosis (LVA) performed after lymphadenectomy can potentially reduce the risk of cancer-related lymphedema (CRL) without compromising the oncological treatment. We present a systematic review of the current evidence on the primary prevention of CRL using preventive lymphatic surgery (PLS). Patients and Methods A comprehensive search across PubMed, Cochrane-EBMR, Web of Science, Ovid Medline (R) and in-process, SCOPUS, and ScienceDirect was performed through December 2020. A meta-analysis with a random-effect method was accomplished. Results Twenty-four studies including 1547 patients fulfilled the inclusion criteria. Overall, 830 prophylactic LVA procedures were performed after oncological treatment, of which 61 developed lymphedema. The pooled cumulative rate of upper extremity lymphedema after axillary lymph node dissection (ALND) and PLS was 5.15% (95% CI, 2.9%-7.5%; p < 0.01). The pooled cumulative rate of lower extremity lymphedema after oncological surgical treatment and PLS was 6.66% (95% CI < 1-13.4%, p-value = 0.5). Pooled analysis showed that PLS reduced the incidence of upper and lower limb lymphedema after lymph node dissection by 18.7 per 100 patients treated (risk difference [RD] - 18.7%, 95% CI - 29.5% to - 7.9%; p < 0.001) and by 30.3 per 100 patients treated (RD - 30.3%, 95% CI - 46.5% to - 14%; p < 0.001), respectively, versus no prophylactic lymphatic reconstruction. Conclusions Low-quality studies and a high risk of bias halt the formulating of strong recommendations in favor of PLS, despite preliminary reports theoretically indicating that the inclusion of PLS may significantly decrease the incidence of CRL.
RESUMEN
Background Posttraumatic lymphedema develops more frequently than expected and reports on its management are scarce in the literature. We aimed to report the clinical outcomes of a case series of posttraumatic lymphedema patients treated with different vascularized lymph node transfers (VLNTs). Patients and Methods Five patients with secondary posttraumatic lower limb lymphedema treated with VLNT were included in this report. The groin-VLNT ( n = 1), supraclavicular-VLNT ( n = 2), and gastroepiploic-VLNT ( n = 2) were implemented. The average flap area was 69.8 cm 2 . Patients underwent postoperative complex decompressive therapy for an average of 10.0 months. Results The average mean circumference reduction rate was 24.4% (range, 10.2-37.6%). Postsurgical reduction in the number of infection episodes per year was observed in all patients. The mean follow-up was 34.2 months. Conclusions VLNT is a promising surgical treatment for posttraumatic lymphedema patients. In our report, VLNT has demonstrated to reduce the volume and number of infections per year in posttraumatic lymphedema.
RESUMEN
Chylous ascites is the leakage of lipid-rich lymph into the peritoneal cavity usually due to disruption of lymphatics or increased peritoneal lymphatic pressure. Various surgical options have been proposed to treat chylous ascites but most have shown suboptimal outcomes. The gastroepiploic vascularized lymph node (GE-VLN) flap has been described previously for the treatment of lymphedema. In chylous ascites, this flap could provide an alternate drainage pathway for the intraperitoneal chylous fluid. The purpose of this report is to present another option for the microsurgical treatment of refractory chylous ascites. Herein, we report two patients with refractory chylous ascites secondary to cancer who have undergone deep inferior epigastric-based lymphatic "cable" flap (DIE-LCF) connected to a pedicle GE-VLN flap. Patients were followed-up for a minimum of 2 years. Within the first 3 months following surgery, the patient's nutritional parameters improved along with drastic reduction of ascites. At 2 years follow-up postoperative abdominal circumference decreased significantly. None required further peritoneal paracentesis and all patients were free of chylous ascites symptoms. In conclusion, the DIE-LCF connected to a pedicle GE-VLN flap could be a feasible option for the microsurgical treatment of refractory chylous ascites.

Background and Objectives: Conservative treatment represents an essential pillar of lymphedema management, along with debulking and physiologic surgeries. Despite the consistent number of treatment options, there is currently no agreement on their indications and possible combinations. When dealing with unusual lymphedema presentation as in the genitalia (Genital Lymphedema-GL), treatment choice becomes even more difficult. The authors aimed to present their targeted algorithm of single and combined treatment modalities for rare GL in order to face this paucity of information. Materials and Methods: Data were collected from a prospectively maintained database since January 1983, and cases of GL that were managed in the authors' department were selected. Only patients that were treated in the authors' institution and presented a minimum follow-up of 3 months were admitted to the current study. Results: From January 1983 to July 2021, 19 patients with GL were recruited. All the patients were male, and their ages ranged from 21 to 73 years old (average: 52). Ten cases (52.6%) presented with ISL (International Society of Lymphology) stage I, five (26.3%) were stage II and four (21.1%) were stage III. GL was managed with conservative treatment (12 cases), LVA (LymphaticoVenous Anastomosis) (3) or surgical excision (4). In a mean follow-up of 7.5 years (range: 3 months-11 years), no major complications occurred, and all cases reached improvements in functional and quality of life terms. Conclusions: Contrary to the predominant thought of the necessity to avoid surgery in unusual lymphedema presentations such as GL, they can be managed using targeted multimodal approaches or by adapting well-known procedures in unusual ways to achieve control of disease progression and improve patients' quality of life.

INTRODUCTION: Management after total pharyngolaryngectomy with free ileocolon flaps can be challenging. Adequate postoperative surgical guidelines are essential to avoid complications. Factors, such as agitation, hypotension, or prolonged mechanical ventilation, might compromise final outcomes. Herein, we describe our experience in the early postoperative care of patients after total pharyngolaryngectomy with immediate reconstruction using the free ileocolon flap. METHODS: This is a retrospective review of all patients who underwent total pharyngolaryngectomy and immediate reconstruction using the free Ileocolon flap. Demographics, etiology of resection, neoadjuvant therapy, surgical time, method of sedation, postoperative use of vasopressors, length of intensive care unit (ICU) stay, time of discontinuation of mechanical ventilation, and complications were recorded and analyzed. RESULTS: Between 2010 and 2015, a total of 34 patients underwent total pharyngolaryngectomy and immediate reconstruction using the free Ileocolon flap. The most common cause of total pharyngolaryngectomy was cancer. Twenty-eight patients had neoadjuvant therapy (radiation). The average surgical time was 11.5 hours (range, 8-14.5 hours), average length of ICU stay was 3 days (range, 2-15 days) with an average time for mechanical ventilation cessation of 3 days (range, 1-20 days). Midazolam and dexmedetomidine were the most common sedatives used during surgery and in the ICU period. Three patients required vasopressors due to hypotension, 2 had unplanned self-extubation from the tracheostomy site, 2 experienced postoperative bleeding, 1 had pneumonia, 4 required unplanned return to the operating room, 2 had partial flap loss, and 1 had complete flap loss. CONCLUSIONS: Overall, a majority of patients recovered well postoperatively with minimal complications and low rate of reoperation. Our research provides a foundation to develop a risk-stratified approach to determine the need for an ICU admission or early transfer to floor care.

BACKGROUND: Vascularized gastroepiploic lymph node flaps have become a popular option to treat patients with extremity lymphedema. Overall, 2 surgical approaches to harvest this flap have been described: laparoscopic and open. In this study, we analyzed complications, harvesting time, and patient satisfaction scores, comparing these 2 techniques. METHODS: Between 2012- and 2018, all patients with extremity lymphedema and candidates for the gastroepiploic flap harvest were included. Two groups were compared: open and laparoscopic approaches. Flap harvest time, postoperative pain, complications, return of gastrointestinal motility, time to discharge, and patient satisfaction scores were assessed. RESULTS: A total of 177 patients were included, of which 126 underwent laparoscopic harvest and 51 patients underwent open approach. Only 2 patients in the laparoscopic group had prior abdominal surgery not related to cancer treatment compared with 7 patients in the open approach (P < 0.01). Average surgical completion time for the laparoscopic versus open approach was 136 and 102 minutes, respectively (P < 0.02). Postoperative complications for the laparoscopic versus open were as follows: 1 patient developed pancreatitis and 2 developed ileus in the laparoscopic approach, whereas 3 patients developed ileus, 1 developed small bowel obstruction, 2 developed superficial site infection, and 1 developed minor wound dehiscence in the open approach. No patient required further surgical intervention. Average return of gastrointestinal function was 1 day (laparoscopic) and 2 days (open), respectively. On a pain scale, pain scores at postoperative day 1 and upon discharge were on average 3 versus 7 and 2 versus 5, respectively (P < 0.05). Lengths of hospital stay were on average 2 days in the laparoscopic group and 5 days in the open group (P < 0.001). Patient satisfaction scores based on pain and scars were significantly better in the laparoscopic group versus open group (P < 0.03). CONCLUSIONS: These data support that a minimal invasive approach is ideal and efficient when resources are available. In addition, the lower complication rate and high patient satisfaction scores give promising feedback to continue offering this technique.

BACKGROUND: Lymphedema treatment is an ongoing challenge. It impacts quality of life due to pain, loss of range of motion of the extremity, and repeated episodes of cellulitis. Different modalities have been used to evaluate lymphedema; some are more error-prone and some are more invasive. However, these measurements are poorly standardized, and intrarater and interrater reliabilities are difficult to achieve. This pilot study aims to assess the feasibility of ultrasound vibroelastography for assessing patients with extremity lymphedema via measuring shear wave speeds of subcutaneous tissues. METHODS: Patients with clinical and lymphoscintigraphic diagnosis of secondary lymphedema in the extremities without prior surgical treatment were included. A 0.1-s harmonic vibration was generated at three frequencies (100, 150, and 200 Hz) by the indenter of a handheld shaker on the skin. An ultrasound probe was used for noninvasively capturing of wave propagation in the subcutaneous tissue. Wave speeds were measured in the subcutaneous tissues of both the control and affected extremities. RESULTS: A total of 11 female patients with secondary lymphedema in the extremities were enrolled in this study. The magnitudes of the wave speeds of the region of interest in the subcutaneous tissue at lymphedema sites in the upper extremity (3.9 ± 0.17 m/s, 5.96 ± 0.67 m/s, and 7.41 ± 1.09 m/s) were statistically higher than those of the control sites (2.1 ± 0.27 m/s, 2.93 ± 0.57 m/s, and 3.56 ± 0.76 m/s) at 100, 150, and 200 Hz (P < 0.05), and at 100 and 200 Hz (P < 0.05) between lymphedema (4.33 ± 0.35 m/s, 4.17 ± 1.00 m/s, and 4.56 ± 0.37 m/s) and controls sites (2.48 ± 0.43 m/s, 2.77 ± 0.55 m/s, and 3.06 ± 0.29 m/s) in the lower extremity. CONCLUSIONS: These preliminary data suggest that ultrasound vibroelastography may be useful in the evaluation of secondary lymphedema and can be a valuable tool to noninvasively track treatment progress.

INTRODUCTION: Reconstruction 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. METHODS: Between 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. RESULTS: Fifteen 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. CONCLUSION: Microscopically 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.
