The Lateral Antebrachial Neurocutaneous Flap: Case Series.

BACKGROUND: The neurocutaneous flap was developed based on the understanding that every superficial cutaneous nerve includes vessels, also known as vasa nervorum or paraneural vessels, which run around and inside the nerves and deliver blood to the skin above. A cutaneous perforator connected to paraneural vessels that vascularize the skin and nerves is referred to as a neurocutaneous perforator. The lateral antebrachial cutaneous nerve (LACN), the most dependable blood supply from the primary underlying veins of the neurocutaneous flap, is the subject of this study. METHODS: We reviewed the results of 30 flap coverage procedures in 10 children. The applied flap was based distally along the radial aspect of the hand and wrist. The pivot point of the flap was located dorsally. This study considered patients with posttraumatic tissue loss, vital structure exposure, or hand contractures with an LACN flap. There was a case-by-case assessment. RESULTS: Thirteen male patients were included; their ages ranged from 6 to 65 years. Demographic data, preoperative cause of trauma, and postoperative complications were collected. Statistically significant improvements were observed after flap healing. CONCLUSIONS: The LACN flap is a more versatile flap with less morbidity than other alternative flaps for coverage of soft tissue defect restoration around the hand, wrist, and distal forearm.

The Vertical Profunda Artery Perforator Flap for Perineal Reconstruction.

BACKGROUND: Colorectal cancer is a significant cause of cancer-related death in the United States with abdominoperineal resection (APR) remaining a necessary procedure for many patients. The resultant defects of this radical operation are complex and characterized by significant tissue voids. Pedicled vertical profunda artery perforator flaps (vPAP) can be used to obliterate these defects in patients receiving minimally invasive APR or when the abdominal donor site is unavailable. METHODS: After receiving local institutional review board approval, a single center, retrospective cohort study from January 2020 to December 2021 was performed assessing pedicled vPAP flap reconstruction of APR defects. Age, sex, body mass index, primary diagnosis, comorbidities, concomitant oncologic procedures, radiation, timing, incorporation of gracilis flaps, follow-up, and complications were compared. RESULTS: Ten patients (70% male) with an average age of 56.2 years and BMI of 27.6 were included in the study. Rectal adenocarcinoma (50%) was the most common indication for APR, followed by rectal squamous cell carcinoma (30%), vulvar squamous cell carcinoma (10%), and Crohn disease (10%). Eighty percent of the patients received radiation, and 70% of reconstructions were delayed after the initial resection. The average length of clinical follow-up was 26.1 months. Concerning major complications, 2 patients were required to return to the operating room due to venous congestion (20%), and 2 patients suffered partial flap failure (20%). Minor complications were perineal dehiscence (50%), abscess requiring percutaneous drainage by interventional radiology (30%), and infection requiring antibiotics (20%). Twenty percent of patients developed fistulas requiring surgical excision. There were no instances of donor site dehiscence, and there was no complete flap loss, indicating successful reconstruction in all included cases. CONCLUSIONS: vPAP flaps are a reliable method to reconstruct perineal defects with less donor-site morbidity than previous reconstructive options. vPAP flaps should be considered in the setting of delayed reconstruction, minimally invasive APRs, and when the abdominal donor site is unavailable.

Paraumbilical Perforator Flap: A Reliable Option for Coverage of Soft Tissue Defects of Forearm and Hand.

Soft tissue injuries of the hand or forearm often results in exposure of tendon or bone which needs coverage with a suitable flap. This prospective observational study was carried out in National Institute of Traumatology and Orthopaedic Rehabilitation (NITOR), Dhaka, Bangladesh from February 2019 to January 2020, to evaluate the use of the pedicled paraumbilical perforator flaps as a reliable flap to cover such defects. Total 34 patients having soft tissue defects in the hand and forearm with exposed tendons, bones or implant were included in this study. All the defects were covered by paraumbilical perforator flap. The defects were caused by road traffic accident (n=22), machinery injury (n=10) and burn injury (n=2). Sixteen patients had defects involving the forearm, six over dorsum of hand, another two over first web space and the rest had defects over two or more areas of forearm, hand and wrist. Lateral extent of flaps was upto anterior axillary line in 41.18% cases and upto mid-axillary line in 55.88% cases. Flap division and final inset was done in second stage after 3 weeks. Donor site closed primarily in all cases, except in two cases where it was covered by skin graft. All the flaps survived with no incidence of flap necrosis, dehiscence or infection after first stage. However, after the division of the flap, two patients developed marginal necrosis of the proximal margin which healed spontaneously by conservative treatment. The mean flap surface area utilized was 108 cm2. Donor area healed well without any major complications. Three patients developing scar hypertrophy were treated with intra-lesional triamcinolone injections. The paraumbilical perforator flap is a reliable option to cover soft tissue defects of hand and forearm due to easier planning and harvesting of the flap, adequate skin paddle and minimum donor site morbidity.

Indocyanine Green Angiography for Detecting Quantitative Perfusion Changes in Deep Inferior Epigastric Perforator Flap Breast Reconstruction With Second Venous Drainage.

BACKGROUND: This study aims to compare perfusion dynamics using indocyanine green videoangiography before and after the creation of a second venous anastomosis between the superficial inferior epigastric vein and the retrograde internal mammary vein (IMV) in deep inferior epigastric perforator (DIEP) flap breast reconstructions. METHODS: Indocyanine green videoangiography performed during DIEP flap reconstructions was analyzed prospectively. The areas of interest were above the perforators with the highest intensity (complete perfusion), the most distal lateral edge of the flap (partial perfusion), and the next lowest intensity (ischemic). We compared the zone intensities before and after the second venous anastomosis, assessing venous drainage patency and functionality. Patient characteristics, operative details, and complications were collected. RESULTS: Seven patients (10 breasts) underwent DIEP reconstruction. Mean age was 54.5 ± 12.4 years. Mean operative duration was 575.5 ± 172.6 minutes. Donors included DIEV (n = 10, 100.0%), superficial inferior epigastric vein (n = 9, 90.0%), and superficial circumflex epigastric vein (n = 1, 10.0%). All DIEVs were anastomosed to the antegrade IMV (n = 10, 100.0%). Superficial inferior epigastric veins were anastomosed to the retrograde IMV (n = 10, 100.0%). Mean peak intensities of the complete perfusion zone before and after the second venous anastomosis were 160.7 ± 42.1 and 188 ± 42.1, respectively ( P = 0.163). Mean peak intensities of the partial perfusion zone were 100.8 ± 21.5 and 152 ± 31.5, respectively ( P < 0.001). Mean peak intensities of the ischemic zone were 90.4 ± 37.4 and 143.4 ± 45.3, respectively ( P = 0.012). CONCLUSION: These findings highlight the potential benefits of the super drainage technique in enhancing perfusion and reducing complications, emphasizing the need for further investigation and consideration of this technique in clinical practice.

A Multi-institutional Analysis of a Textbook Outcome Among Patients Undergoing Microvascular Breast Reconstruction.

BACKGROUND: Individual outcomes may not accurately reflect the quality of perioperative care. Textbook outcomes (TOs) are composite metrics that provide a comprehensive evaluation of hospital performance and surgical quality. This study aimed to investigate the prevalence and predictors of TOs in a multi-institutional cohort of patients who underwent breast reconstruction with deep inferior epigastric artery perforator flaps. METHODS: For autologous reconstruction, a TO was previously defined as a procedure without intraoperative complications, reoperation, infection requiring intravenous antibiotics, readmission, mortality, systemic complications, operative duration ≤12 hours for bilateral and ≤10 hours for unilateral/stacked reconstruction, and length of stay (LOS) ≤5 days. We investigated associations between patient-level factors and achieving a TO using multivariable regression analysis. RESULTS: Of 1000 patients, most (73.2%) met a TO. The most common reasons for deviation from a TO were reoperation (9.6%), prolonged operative time (9.5%), and prolonged LOS (9.2%). On univariate analysis, tobacco use, obesity, widowed/divorced marital status, and contralateral prophylactic mastectomy or bilateral reconstruction were associated with a lower likelihood of TOs (P < 0.05). After adjustment, bilateral prophylactic mastectomy (odds ratio [OR], 5.71; P = 0.029) and hormonal therapy (OR, 1.53; P = 0.050) were associated with a higher likelihood of TOs; higher body mass index (OR, 0.91; P = <0.001) was associated with a lower likelihood. CONCLUSION: Approximately 30% of patients did not achieve a TO, and the likelihood of achieving a TO was influenced by patient and procedural factors. Future studies should investigate how this metric may be used to evaluate patient and hospital-level performance to improve the quality of care in reconstructive surgery.

The value of microvascular breast reconstruction: Cost equivalence of TRAM and DIEP flaps implications in the era of CMS reforms.

BACKGROUND: Recent CMS billing changes have raised concerns about insurance coverage for deep inferior epigastric perforator (DIEP) flap breast reconstruction. This study compared the costs and utilization of transverse rectus abdominis myocutaneous (TRAM), DIEP, and latissimus dorsi (LD) flaps in breast reconstruction. METHOD: The study utilized the National Inpatient Sample database to identify female patients who underwent DIEP, TRAM, and LD flap procedures from 2016 to 2019. Key data such as patient demographics, length of stay, complications, and costs (adjusted to 2021 USD) were analyzed, focusing on differences across the flap types. RESULTS: A total of 17,770 weighted patient encounters were identified, with the median age being 51. The majority underwent DIEP flaps (73.5%), followed by TRAM (14.2%) and LD (12.1%) flaps. The findings revealed that DIEP and TRAM flaps had a similar length of stay (LOS), while LD flaps typically had a shorter LOS. The total hospital charges to costs using cost-to-charge ratio were also comparable between DIEP and TRAM flaps, whereas LD flaps were significantly less expensive. Factors such as income quartile, primary payer of hospitalization, and geographic region significantly influenced flap choice. CONCLUSION: The study's results appear to contradict the prevailing notion that TRAM flaps are more cost-effective than DIEP flaps. The total hospital charges to costs using cost-to-charge ratio and hospital stays associated with TRAM and DIEP flaps were found to be similar. These findings suggest that changes in the insurance landscape, which may limit the use of DIEP flaps, could undermine patient autonomy while not necessarily reducing healthcare costs. Such policy shifts could favor less costly options like the LD flap, potentially altering the landscape of microvascular breast reconstruction.

Alternatives to the Gold Standard: A Systematic Review of Profunda Artery Perforator and Lumbar Artery Perforator Flaps for Breast Reconstruction.

INTRODUCTION: Breast reconstruction with the deep inferior epigastric perforator (DIEP) flap is the current gold-standard autologous option. The profunda artery perforator (PAP) and lumbar artery perforator (LAP) flaps have more recently been described as alternatives for patients who are not candidates for a DIEP flap. The aim of this study was to review the survival and complication rates of PAP and LAP flaps, using the DIEP flap as a benchmark. METHODS: A literature search was conducted using PubMed, MEDLINE, Embase, BIOSIS, Web of Science, and Cochrane databases. Papers were screened by title and abstract, and full texts reviewed by three independent blinded reviewers. Quality was assessed using MINORS criteria. RESULTS: Sixty-three studies were included, for a total of 745 PAP, 62 stacked PAP, 187 LAP, and 23,748 DIEP flap breast reconstructions. The PAP (98.3%) had comparable success rate to DIEP (98.4%), and the stacked PAP (88.7%) and LAP (92.5%) success rate was significantly lower (P < 0.0001). The PAP and LAP groups both had a low incidence of fat necrosis. However, the revision rate for the LAP group was 16.1% whereas the PAP group was 3.3%. Donor site wound dehiscence rate was 2.9 in the LAP group and 9.1% in the PAP group. CONCLUSIONS: Profunda artery perforator and DIEP flaps demonstrate very high rates of overall survival. The LAP flap has a lower survival rate. This review highlights the survival and complication rates of these alternative flaps, which may help clinicians in guiding autologous reconstruction technique when a DIEP flap is unavailable.

Subdermal dissection technique for pure skin SCIA and ALT perforator flaps in burns and trauma defects: Clinical experience.

BACKGROUND: The pure skin perforator (PSP) flap is gaining popularity for its remarkable thinness. The subdermal dissection technique was recently introduced, allowing for a quicker elevation of a PSP flap. In this report, we present our two-year experience utilizing subdermal dissection for harvesting PSP flaps. METHODS: All patients who had undergone PSP flap reconstruction at our hospital from February 2021 to February 2023 were included. Demographic data, intraoperative variables, flap characteristics, and postoperative outcomes were collected. Surgical planning involved locating the perforator using ultrasound and harvesting the flap using the subdermal dissection technique. RESULTS: A total of 26 PSP flap reconstructions were conducted on 24 patients aged between 15 and 86 years. The flaps were based on perforators issuing from the superficial circumflex iliac artery in 24 cases, and from the descending branch of the lateral circumflex femoral artery in 2 cases. Flap sizes ranged from 3 × 1.5 cm to 19 × 6 cm, with a mean thickness of 3.48 mm. The average time for flap harvest was 131.92 min. Postoperatively, we observed four cases of partial necrosis, 1 total flap loss, and 2 instances of vascular thrombosis at the anastomosis site. The flaps exhibited good pliability without contracture, and no debulking procedures were required during the follow-up period (minimum 6 months, range 6-24; mean 9.4615). CONCLUSION: The subdermal dissection technique is a safe and efficient approach for elevating PSP flaps. Our initial experience with this technique has been encouraging, and it currently serves as our preferred reconstructive option for defects requiring thin reconstruction.

Outcomes of internal mammary artery perforator flap in head and neck reconstruction: A systematic review.

This study aims to evaluate the functional and prognostic outcomes associated with the internal mammary artery perforator (IMAP) flap in various head and neck defect repairs, given the current lack of clarity on its effectiveness. We performed a systematic review of various databases: PubMed, Embase, Scopus, Web of Science, and ScienceDirect using keywords such as "Internal mammary artery perforator flap" and "IMAP." Screening and data extractions were performed by two individual reviewers. Articles were considered eligible if they included sufficient information on IMAP flap features, their applications in the head and neck, and outcomes. From 264 articles analyzed, 24 studies were included for qualitative analysis. Out of which, 125 patients who received internal mammary artery perforator flaps were included. Most of the patients, 103 (88%), received pedicled IMAP flaps, and 22 (12%) received IMAP free flaps. The second internal mammary artery (IMA) was favored as the single perforator (81.5%), with the combination of the first and second IMA being the primary choice for dual perforators (92.5%). IMAP flaps were predominantly single perforator flaps (65%), with 35% being dual perforator flaps. Among various applications, IMAP flaps are commonly employed in the reconstruction of neck defects (25.5%), pharyngocutaneous fistula repair (20.8%), and burn scar contracture restoration (8%). Only seven (5.6%) patients had flap complications, including venous congestion (1.6%), partial necrosis (1.6%), complete necrosis (1.6%), and incision dehiscence (0.8%). Donor sites were predominantly closed by the primary closure (92%). 3.2% of donor sites had minor complications. The average follow-up was 12.6 (IQR: 6-18) months. This systematic review highlights the effectiveness and safety of IMAP flaps in head and neck reconstruction, with positive outcomes and minimal complications.

Research Advances in Vascular Remodeling in Choke Vessels of Perforator Flap: A Systematic Review.

BACKGROUND: As a significant bridge between perforasomes, choke vessels are the key structure of blood supply expansion, also a prerequisite for preventing distal ischemic necrosis of the multiterritory perforator flap, where the remodeling of choke vessels after flap elevation plays an essential role. This systematic review highlights the underlying mechanisms and clinical ways to promote remodeling of choke vessels, as well as experimental observation approaches to further guide researchers. METHODS: A systematic review was conducted from 1975 to 2023 through PubMed, EMBASE, Web of Science, and Cochrane database with the key words "choke vessels" and "perforator flap" to investigate the mechanisms and ways to promote remodeling of choke vessels as well as observation approaches. The inclusion criteria and exclusion criteria were set to screen the literature. RESULTS: A total of 94 literatures were obtained through database retrieval. After removing the duplicate literature, reading the title and abstract, and reviewing the full text finally, 33 articles were included in the final study. CONCLUSIONS: The underlying remodeling of choke vessels may be related to fluid shear stress, hypoxia, and inflammation. The clinical ways to promote remodeling of choke vessels include surgical delay, arterial supercharge, venous superdrainage, drugs, and stem cells. Various experimental methods of observing microvascular morphology allow for a comprehensive research of choke vessels.

A Comprehensive Flap Classification: Beyond the Reconstructive Ladder.

ABSTRACT: Perforator flaps have progressed massively in the last years. The improved vascular imaging techniques and the use of supermicrosurgery have shifted the practice from the traditional predefined angiosomal flaps to the endless variations of custom-made flaps. In this article, we propose a broadened classification of free-style flaps in 3 categories, the angiosomal, including all traditional perforator flaps and their variations, the extra-angiosomal, including flaps that are manufactured to include tissue from a different angiosome, such as turbocharging or supercharging a flap, and neoangiosomal flaps, which are based on the process of neoangiogenesis on autologous or allogenous tissue, such as the venous flow-through flap and integra flap. With this classification, we hope to help unify the classifications and, by doing so, facilitate the exchange of ideas, techniques and knowledge.MeSH terms: surgical flap / classification, terminology as topic.

Feasibility of perforator flaps in Day surgery. A retrospective study through a two-years' experience.

BACKGROUND: Day surgery is developing and its popularity is increasing for a variety of reasons: economic constraints, changes in professional practices, a greater adhesion of the patient. In an era of progress in surgical procedures, pedicled-perforator flaps reducing donor site morbidity and avoiding micro-anastomosis could take their place in Day surgery if planned and managed by an experienced team. METHODS: In the period January 2019 to January 2021, we performed perforator flaps for soft tissue coverage in ambulatory setting. The patients were included retrospectively and data were collected by reviewing the medical records. Major and minor complications were recorded. RESULTS: The retrospective cohort included 32 surgical procedures in 32 patients. In all cases, perforator flaps were realized for resurfacing soft tissue defects consequent to oncodermatology surgery (84.3%), soft tissue sarcoma surgery (12.5%), invasive ductal breast carcinoma (3.1%). Major complications needing a surgical revision overcame 3/32 times (9.4%). In these cases, a failure requiring the drop off the flap overcame once. The average wound healing time was of 33 days (15-90) and the mean duration of follow-up was 9.6 months (1-22). CONCLUSION: The low complication rate in our series suggests that this first experience on perforator flaps in outpatient surgery is promising in terms of safety and feasibility. Day surgery could be a practical option for this type of surgical procedures avoiding the conventional department's saturation and allowing the delivery of proper surgical cares.

Repair of buccal mucosa and floor of mouth defects using keystone design perforator island flap.

OBJECTIVE: To assess the feasibility of utilizing the keystone design perforator island flap (KDPIF) for the repair of small to medium-sized defects in the buccal mucosa and floor of mouth (cT1-2 stage tumor). STUDY DESIGN: We conducted a retrospective analysis of eight patients who underwent KDPIF to address oral defects at the Affiliated Hospital of Qingdao University between June 2021 and September 2022. Patient information, including medical history, defect site, flap size, operative time, hospital stay, complications, and postoperative recovery of oral function, was comprehensively evaluated. RESULTS: Eight patients (6 females and 2 males) underwent reconstruction using KDPIF. The mean operation time was 58.5 minutes (55-63 minutes), with an average length of stay of 3.5 days (3-5 days). None of the 8 cases (100%) exhibited flap splitting necrosis or infection. Moreover, no scar contracture was observed, and oral functions, including the degree of opening, type of opening, tongue mobility, speech function, and swallowing function, were successfully restored. One patient (12.5%) experienced bleeding from the incision on the first postoperative day, but following compression, hemostasis was achieved, and the incision healed well. CONCLUSIONS: KDPIF demonstrates technical feasibility and suitability for repairing small to medium-sized buccal mucosa and floor of mouth defects (cT1-2).

Application of extended ulnar parametacarpal perforator free flap for the reconstruction of total pulp defect of the thumb: A case report.

Many procedures are available for the coverage of thumb pulp defects; however, to gain thumb function and esthetics, a similar tissue is desirable. If the length of the longitudinal defect is <2 cm, a volar advancement flap is appropriate; however, if the flap is >2 cm long or wider, retrograde or free flaps are required. Here, we present a case of thumb pulp reconstruction using an extended ulnar parametacarpal perforator (UPM) flap, which achieved excellent functional and esthetic outcomes. A 46-year-old man underwent reconstruction surgery of his thumb, which was a degloved total pulp. A sensate 5.2 × 3.2 cm UPM flap was designed on the ulnar side of the right palm and transferred to his thumb. The flap donor site was covered with a V-Y advancement flap on the dorsal side of the right hand. At 12 months postoperatively, the patient achieved a functional and natural thumb appearance with high satisfaction. The UPM flap can offer soft tissue similar to the pulp region in the digit without a palm scar at the donor site. This extended application is suitable for the reconstruction of a total pulp defect of the digit and is an alternative option for a hemi-pulp flap from the toe area.

Developments in Hand Surgery: Experience from a Tertiary Hospital of Northern Bangladesh.

Hand Surgery is a specialized branch of Plastic and Reconstructive surgery. There are many conditions that require hand surgery, for example, congenital deformity, electric or flame burn, mechanical or road traffic injury, and post burn or post traumatic deformity. A retrospective observational study was conducted in the department of Burn and Plastic surgery, Mymensingh Medical College Hospital, Bangladesh during a 2 years period extending from 9th September 2021 to 8th September 2023. The objective of this study was to see the hand surgery status in a tertiary hospital of Bangladesh during the post Covid pandemic period. During this period 236 hand surgery procedures were performed in 176 patients. The age of the patients ranged from 02 to 78 years (Mean 31.14±1.52). One hundred and four (59.0%) were male and 72(41.0%) were female. Thirty-four (19.32%) patients had co-morbidities e.g., Epilepsy, Diabetes Mellitus, Chronic Kidney Diseases and HBsAg +ve. Causes of surgery included, wound due to electric burn 49(27.84%), flame burn 36(20.45%), post traumatic 24(13.64%), post infective 11(06.25%), tumor excision 02(2.24%), Dupuytren's contracture 03(1.70%), congenital anomalies 06(3.41%), post burn scar contractures 41(23.29%), nerve injury 01(00.57%) and carpal tunnel syndrome 01 (00.57%). Procedures were performed: post burn scar contracture release 41(17.37%), syndactly release 06(2.54%), release of post traumatic contracture 06(2.54%), carpal tunnel release 01(00.42%), release of Dupuytren's contracture 03(01.27%), nerve repair 01(00.42%), debridement, amputation and Fillet flap 29(12.29%), split thickness skin graft 46 (19.49%), V-Y advancement flap 06(2.54%), transposition flap 18(07.63%), cross finger flap 16 (06.78%), reverse cross finger flap 02 (00.85%), first dorsal metacarpal artery (FDMA) flap 05 (02.12%), reverse FDMA flap 01 (00.42%), metacarpal artery perforator flap 08(3.39%), radial artery perforator flap 04(01.69%), posterior interosseous artery flap 05(2.12%), abdominal flap 11(04.46%) and flap division and insetting 27(11.44%). Outcome of surgery was satisfactory in 225(95.34%) and 11(04.46%) cases had complications (p value 0.453), which was not significant. So, it can be concluded that the outcome of various types of hand surgery procedures in tertiary hospital of northern Bangladesh during the post Covid period was satisfactory overall.

[Clinical diagnosis and treatment of 14 cases of scar cancer ulcer wound on head and face].

Objective: To analyze the clinical characteristics of scar cancer ulcer wound of head and face, and to investigate its diagnosis and treatment. Methods: The clinical data of 14 patients with head and facial scar cancer ulcer wounds who met the selection criteria and admitted between January 2021 and March 2022 were retrospectively analyzed. There were 8 males and 6 females. The age of onset ranged from 21 to 81 years with an average age of 61.6 years. The incubation period ranged from 1 month to 70 years, with a median of 4 years. Site of the disease included 7 cases of head, 6 cases of maxillofacial region, and 1 case of neck region. Injury factors included trauma in 5 cases, scratch in 5 cases, scalding in 2 cases, burn in 1 case, and needle puncture in 1 case. Pathological results showed squamous cell carcinoma in 9 cases, basal cell carcinoma in 3 cases, sebaceous adenocarcinoma in 1 case, papillary sweat duct cystadenoma combined with tubular apocrine sweat gland adenoma in 1 case. There was 1 case of simple extensive tumor resection, 1 case of extensive tumor resection and skin grafting repair, 7 cases of extensive tumor resection and local flap repair, and 5 cases of extensive tumor resection and free flap repair. Results: All the 14 patients were followed up 16-33 months (mean, 27.8 months). Two patients (14.29%) had scar cancer ulcer wound recurrence, of which 1 patient recurred at 2 years after 2 courses of postoperative chemotherapy, and was still alive after oral traditional Chinese medicine treatment. One patient relapsed at 1 year after operation and died after 2 courses of chemotherapy. One patient underwent extensive resection of the left eye and periocular tumor and the transfer and repair of the chimaeric muscle axial flap with the perforating branch of the descending branch of the left lateral circumflex femoral artery, but the incision healing was poor after operation, and healed well after anti-infection and debridement suture. The wounds of other patients with scar cancer ulcer did not recur, and the wounds healed well. Conclusion: Scar cancer ulcer wound of the head and face is common in the middle-aged and elderly male, and the main pathological type is squamous cell carcinoma. Local extensive resection, skin grafting, or flap transfer repair are the main treatment methods. Early active treatment of wounds after various injuries to avoid scar repeated rupture and infection is the foundamental prevention of scar cancer.

Robotic Repair: An Alternative Technique for Rectus Diastasis and Abdominal Bulge Following DIEP Flap Breast Reconstruction.

BACKGROUND: The deep inferior epigastric artery perforator (DIEP) flap is the gold standard in autologous breast reconstruction. Despite advances in perforator dissection, abdominal morbidity still occurs. Traditional rectus diastasis (RD), abdominal bulge, and hernia repair with open techniques are associated with higher complication rates and recurrence. OBJECTIVES: We present a novel case series of robotic repair of symptomatic RD and/or abdominal bulge with concurrent hernia following DIEP flap surgery. METHODS: A single-center, retrospective review was conducted of 10 patients who underwent bilateral DIEP flap breast reconstruction and subsequent robotic repair of RD and/or abdominal bulge and hernia. Preoperative demographics and postoperative clinical outcomes were reviewed. RD up to 5 cm, abdominal bulge, and any concurrent ventral/umbilical hernias were repaired robotically with retrorectus plication and macroporous mesh reinforcement. RESULTS: The average age and BMI were 49 years (range 41-63) and 31 kg/m2 (range 26-44), respectively. The average number of perforators harvested per flap was 2.5 (range 1-4). Average RD and hernia size were 3.95 cm (range 2-5) and 5.8 cm2 (1-15), respectively. Eight patients stayed 1 night in the hospital, and 2 went home the same day as the robotic repair. No patients were converted to open technique and none experienced complications within 30 days. CONCLUSIONS: For patients who experience donor site morbidity following DIEP flap breast reconstruction, minimally invasive robotic repair of RD and/or abdominal bulge with hernia can be performed with mesh reinforcement. This technique is effective, with low complication rates, and should be considered over open repair.
