RESUMO
Donor lymphocyte infusion (DLI) is performed to augment an anti-tumor immune response or ensure donor stem cells remain engrafted following allogeneic stem cell transplantation but may induce graft-versus-host disease (GVHD) involving skin, intestine, and liver. Although hepatic involvement of GVHD can manifest as mild to severe hepatitis, few reports have mentioned acute severe liver dysfunction with encephalopathy. We experienced a case of acute severe liver dysfunction with semicoma after DLI in a patient with relapsed multiple myeloma following allogeneic stem cell transplantation, in whom chronic viral hepatitis B had been suppressed by antiviral treatment. The patient recovered after high-dose glucocorticoid administration based on an assessment of hepatic GVHD. Clinicians should be aware of the possibility of this catastrophic hepatic complication after DLI in hematologic disorders.

Many surgical techniques for managing epicanthal folds have been reported, but their main drawbacks include a noticeable scar in Asians, acute medial canthal angle, and applicability only in mild or moderate epicanthal folds. This study described a novel surgical technique, Y-W epicanthoplasty, and assessed the medial canthal shape and scarring in patients who underwent Y-W epicanthoplasty. Patients with moderate or severe epicanthal folds between January 2004 and February 2017 were included in this study. Pre- and postoperative intercanthal distance (ICD), inner canthal angle (ICA), and interpupillary distance (IPD) were measured. The ICD ratios (ICD/IPD) and extent of postoperative scarring were evaluated. A Y-W epicanthoplasty was performed on 18 patients. The ICD ratio of the total study cohort showed a significant reduction following surgery (preoperative ICD ratio=0.62±0.04, postoperative ICD ratio=0.58±0.03, P<0.001). The ICA was 51.8±7.7° and 49.8±5.6° in the pre- and postoperative periods, respectively (P=0.086) Eleven patients showed no apparent scar, and 6 patients were found to have minimal scarring that was visible only under close inspection. One patient had a hypertrophic scar that was successfully managed with triamcinolone acetonide injections. Y-W epicanthoplasty can provide good aesthetic results without a visible scar in patients with moderate-to-severe epicanthal folds. The Y-W epicanthoplasty avoids a medially extended skin incision and excessive tension on the skin flaps. Moreover, an acutely shaped or webbed medial canthus after epicanthoplasty can be prevented by adding a small triangular flap. The Y-W epicanthoplasty procedure is simple and straightforward, and it is appropriate for moderate-to-severe epicanthal fold correction.
RESUMO
INTRODUCTION: In secondary cleft lip and nasal deformity (CLND) correction, structural grafts are commonly used to control the nasal tip and restore the symmetry of the ala. However, the septal cartilage in Asians often weak and small. Biocompatible absorbable materials are alternatives to autologous grafts. This study assessed the surgical outcomes and complications of poly lactic-co-glycolic acid (PLGA) plate grafts in secondary CLND correction. METHODS: This study was retrospectively analyzed for patients who underwent secondary rhinoplasty for unilateral CLND correction between March 2015 and November 2020. Using open rhinoplasty, the PLGA plate was grafted as a columellar strut. Clinical photographs taken at the initial (T0) and follow-up visits (T1: short-term, T2: long-term) were analyzed and anthropometric parameters, such as nostril height and width, dome height, and tip height, were measured. RESULTS: Twenty-four patients were included in this study. The mean T1 and T2 periods were 1.0 ± 0.4 and 15.5 ± 3.1 months, respectively. The nostril height ratio increased from 0.78 ± 0.12 at T0 to 0.88 ± 0.08 at T1 and 0.86 ± 0.09 at T2 (p < 0.001; Relapse ratio -2.6 ± 6.7%). The tip height ratio increased from 0.60 ± 0.07 (T0) to 0.66 ± 0.05 (T2) (Relapse ratio -3.7 ± 3.0%). CONCLUSIONS: The PLGA plate graft provided stable nasal tip projection and alar symmetry without major complications. It can be a good option for patients lacking available septal and concha cartilages or apprehensive of additional scarring.

BACKGROUND: Transgender and intersex populations have long remained under-documented in South Korea, largely due to the absence of comprehensive epidemiological data. With increasing societal acknowledgment, there's an urgent need to understand the demographics and health challenges faced by these communities. METHODS: This retrospective, large-scale data study included people who received the F64 codes from the Korean Health Insurance Review & Assessment Service between January 2007 and December 2021. Demographics, gender-affirmative treatments, and psychiatric related medications were examined. RESULTS: Between 2007 and 2021, 8,602 patients were diagnosed with "gender identity disorder" and 45 with "intersex." A steadily increasing annual prevalence was observed, peaking at 986 cases in 2021. The majority (79.8%) were aged between 10 and 30. Nearly half (53.2%) exhibited mental and behavioral disorders. Two-thirds had been prescribed anxiolytics or sedatives either before or after diagnosis. Merely 12.1% received hormone therapy covered by health insurance. CONCLUSION: This is the first large-scale study highlighting the demographics and clinical characteristics of the transgender and intersex populations in Korea. The study reveals a consistent growth of these communities over the past 15 years, with a significant proportion under 30 years of age facing mental and behavioral challenges. Findings underscore the need for targeted healthcare interventions, early psychological support, and comprehensive insurance coverage tailored to the specific needs of these individuals in Korea.

BACKGROUND: An association between environmental pollutants and alcohol-related liver disease (ALD) has not been determined until now. The objectives of this study were to examine the association of the pollutants with ALD, and whether the pollutants together increased the risk of ALD. METHODS: Data were extracted from the Korea National Health and Nutrition Examination Survey (2010-2013 and 2016-2017; n = 11,993). Blood levels of lead, cadmium, and mercury were measured. ALD was defined by a combination of excessive alcohol consumption and ALD/non-alcoholic fatty liver disease index > 0. The aspartate aminotransferase-to-platelet ratio index and fibrosis (FIB)-4 score were used to evaluate ALD FIB. RESULTS: The odds ratios (ORs) of ALD for the highest versus the lowest quartiles of exposure were for lead, 7.39 (95% confidence interval [CI], 5.51-9.91); cadmium, 1.68 (95% CI, 1.32-2.14); and mercury, 5.03 (95% CI, 3.88-6.53). Adjusting for age, gender, smoking, occupation, education, and personal income attenuated the associations but indicated significant positive trends (all Ptrend < 0.001). A positive additive interaction between cadmium and lead was observed. The relative excess OR due to the interaction was 0.96 (95% CI, 0.41-1.51); synergy index = 2.92 (95% CI, 0.97-8.80). Among 951 subjects with ALD, advanced FIB was associated with lead and cadmium (OR, 3.46, 95% CI, 1.84-6.53; OR, 8.50, 95% CI, 2.54-28.42, respectively), but not with mercury. The effect estimates for lead and cadmium remained significant even after adjustment for daily alcohol intake. CONCLUSION: Blood levels of lead, cadmium, and mercury were significantly associated not only with the risk of ALD but also with ALD FIB. Cadmium and lead have synergistic effects that increase the risk of ALD.

Background/Aims: We investigated the incidences of overall and site-specific malignancies and chemopreventive effects of statin, metformin, and aspirin in patients with ulcerative colitis. Methods: We collected data using the Health Insurance Review and Assessment claims database from January 2007 to April 2020. Results: The overall malignancy risk among the 35,189 ulcerative colitis patients was similar to that of the general population (standardized incidence ratio, 0.94; 95% confidence interval, 0.88-1.00). In male patients, standardized incidence ratios were high for thyroid cancer and low for stomach cancer, colorectal cancer, liver cancer, and lung cancer. Concurrently, standard incidence ratios were high for liver cancer and central nervous system cancer in female patients. While 122 cases of colorectal cancer occurred in the study patients, the standardized incidence ratio was 0.83 (95% confidence interval, 0.69-0.99). Treatment for ulcerative colitis was not associated with an increased adjusted hazard ratio, while comorbidities increased it for all malignancies. Treatment for ulcerative colitis was associated with an increased adjusted hazard ratio, while comorbidities did not increase it for colorectal cancer. After adjusting for age, sex, comorbidities, and ulcerative colitis treatment, statins showed a dose-dependent chemopreventive effect for all malignancies (P=0.002), while metformin and aspirin did not show any. Conclusions: In ulcerative colitis patients, standardized incidence ratios for all malignancies and colorectal cancer did not increase. Adjusted hazard ratios for all malignancies increased with comorbidities and those for colorectal cancer with ulcerative colitis treatment. Statins have a dose-dependent chemopreventive effect for all malignancies.
RESUMO
The ultimate goal of cleft palate repair is to achieve an intact palate with the separation of the oral and nasal cavities. However, some patients develop an oronasal fistula in the secondary palate after palatoplasty. Postoperatively, a secondary palatal oronasal fistula may develop, leading to functional problems. In this study, we describe a patient with recurrent oronasal fistula and alveolar cleft with multiple failed previous reconstructions at another clinic. The oronasal fistula and alveolar cleft were repaired using a tongue flap and an iliac bone graft, respectively. The patient demonstrated excellent clinical progress with no recurrence of the oronasal fistula at the 1-year follow-up.
RESUMO
BACKGROUND: Acellular dermal matrices (ADMs) play an essential role in prepectoral implant-based breast reconstructions; however, the most appropriate method for ADMs is unknown. METHODS: We conducted a retrospective analysis of our institutional database. Patients who underwent mastectomy and prepectoral breast reconstruction using tissue expanders or breast implants covered with ADMs between March 2018 and June 2021 were included. Patient characteristics, postoperative complications, and long-term outcomes were investigated. RESULTS: In total, 112 patients (126 breasts) were included. The anterior tenting and wrapping techniques were used in the reconstruction of 32 (25.3%) and 94 (74.7%) breasts, respectively. Using propensity score matching, nine breasts were selected for each technique within the direct-to-implant reconstruction group, while 16 breasts were selected for each technique within the 2-stage reconstruction group. The choice of technique (anterior vs. wrapping) in implementing ADM did not generate any significant differences in postoperative complications, including seroma formation and capsular contracture, for the direct-to-implant and 2-stage reconstruction groups. Regarding the direct-to-implant reconstruction group, the average postoperative drain volume was less in the anterior tenting group than that in the wrapping group (anterior tenting vs. wrapping; 495.09 ± 156.118 mL vs. 673.43 ± 307.954 mL, p = 0.006), but the difference was insignificant after propensity score matching. CONCLUSION: We report our experience with covering prosthetic devices with ADMs during postmastectomy breast reconstruction. No differences in the postoperative drain volume or postoperative outcomes were found between the study groups. Future studies are needed to determine the method that provides the most satisfactory results.

BACKGROUND: Recurrent laryngeal nerve (RLN) injury and the resulting paralysis is the most common and known complication of thyroid surgery. Several surgical techniques, such as medialization thyroplasty with or without arytenoid adduction and injection laryngoplasty, have been developed to treat RLN injury, but these procedures have specific limitations and complications. In this study, we present the outcomes for our patients who underwent immediate RLN reconstruction during thyroid surgery by analyzing both subjective and objective outcomes. METHODS: A retrospective study was conducted for patients who underwent total or subtotal thyroidectomy between May 2012 and March 2020. Among them, patients who underwent immediate RLN reconstruction due to unilateral RLN injury were followed for at least 12 months. The voice perceptual evaluation, acoustic analysis, voice range profile, and Voice Handicap Index (VHI) scores were obtained preoperatively, 1 month, 6 months, and 12 months after surgery. RESULTS: Among the 11 patients, 6 patients (54.5%) underwent direct anastomosis, and 5 patients (45.5%) underwent nerve grafts using ansa cervicalis and great auricular nerve. The grade and breathiness in the GRBAS (grade, roughness, breathiness, asthenia, and strain) scale and jitter item showed significant improvement at 12 months postoperatively, and although not statistically significant, the rest of the items also tended to improve. The total, functional, and physical scores on VHI improved significantly at 12 months postoperatively. Moreover, when comparing the voice analysis of the direct anastomosis group and the nerve graft group, there was no significant difference between the groups in objective and subjective results. CONCLUSION: Immediate RLN reconstruction demonstrated significant voice improvement postoperatively, and reconstructing the nerve immediately and combining follow-up treatment in the event of RLN injury will greatly help patients improve their long-term voice outcomes.
RESUMO
This study aimed to quantitatively analyze the degree and vector of commissure excursion following intraoral orthodromic temporalis transfer. Patients with unilateral facial paralysis who underwent intraoral temporalis transfer were included. Intra-oral coronoidectomy was followed by submucosa tunneling through two vertical intraoral incisions to fixate the temporalis tendon to the perioral location. Oral commissure excursion, upper lip and commissure height differences, and smile angle were measured. Postoperatively, the symmetry of commissure excursion improved in repose (affected side: 114.6 ± 7.0 mm, non-affected side: 115.2 ± 4.9 mm, p = 0.134), while asymmetry arose in smiling (affected side: 30.7 ± 3.4 mm, non-affected side: 34.5 ± 4.4 mm, p = 0.001). Furthermore, the postoperative smile angle demonstrated insufficient vertical movement on the affected side during smiling (affected side: 115.6 ± 5.8°, non-affected side: 118.4 ± 4.9°, p = 0.002) but no significant difference in repose (p = 0.134). Within the limitations of the study it seems that intraoral orthodromic temporalis transfer yields excellent resting symmetry, but smile asymmetry may occur owing to insufficient oral commissure excursion. Nevertheless, as a minimally invasive surgery, this technique can obviate visible scars and benefit patients wishing for the same and can have excellent resting symmetry.

RATIONALE: The RoboticScope (BHS Technologies GmbH, Innsbruck, Austria) is a robotic exoscope, which consists of a robotic arm that holds a 3-dimensional camera. It has an advantage that a surgeon can perform an operation comfortably with a favorable ergonomic position. Also, it allows the delivery of clear and high-quality visualization for surgeons. In this study, we would like to share our initial experience with this newly developed microscope technology in lymphaticovenular anastomosis (LVA). To the best of our knowledge, it is the first experience of LVA using this microscope in Asia. PATIENT CONCERNS: A 65-year-old woman presented with bilateral lower extremity lymphedema after a hysterectomy that was performed 25 years back. Despite complex decongestive physiotherapy, an edematous symptom in both legs worsened. DIAGNOSES: In lymphoscintigraphy, a decreased visualization of main lymphatic flow in both the lower extremities was evident which was further suggestive of lymphatic obstruction. INTERVENTION: Although both sides showed edematous symptoms, we decided to proceed with the surgery on the left side first, because of the worsened condition. Four LVAs were performed at the dorsum of the foot (×2), ankle, and the superior edge of the knee using RoboticScope. OUTCOMES: At 6-months follow-up after operation, the postoperative circumference diameters were improved than preoperative in 10 cm above the knee (45 cm vs 49 cm), 10cm below the knee (37 cm vs 41 cm) and lateral malleolus (25 cm vs 28 cm). The lower extremity lymphedema index was also improved from 346.7 to 287.4 postoperatively. The RoboticScope provided a high-resolution image and a favorable ergonomic position during an operation. LESSONS: The results represent the possibility of the application of a robotic microscope in the field of microsurgery, and further studies are necessitated to confirm the efficacy of this system.

Background: An immediate lymphatic reconstruction (ILR) combining axillary reverse lymphatic mapping (ARLM) and lymphovenous anastomosis (LVA) has been gradually in the spotlight as a novel surgical technique to prevent lymphedema. In this study, we investigate the preventive effect of ILR for the risk of upper extremity lymphedema. We will compare the incidence of postoperative lymphedema between the ILR treatment group and the no-try or failure group during the same period with analysis of the effects of different variables. Methods: In this retrospective cohort study, we analyzed 213 patients who had undergone mastectomy for node-positive unilateral breast cancer in our institution between November 1, 2019 and February 28, 2021. To assess the effect of preventive ILR, we divided the patients into a treatment group (n=30) and a control group (n=183). Univariate and multivariate Cox proportional hazards regression models were used to evaluate the association between ILR and lymphedema occurrence. Results: Of the 30 patients who were attempted, we successfully performed ILRs in 26 patients (86.7%). During a mean follow-up of 14 months, one patient (3.8%) was confirmed to have upper extremity lymphedema in the treatment group, whereas 14 out of 183 patients (7.7%) were diagnosed in the control group. In multivariate analysis, ILR success showed a borderline significant decrease in risk of lymphedema [hazard ratio (HR) =0.174; 95% confidence interval (CI): 0.022-1.374; P=0.097]. Conclusions: Our results suggested that ILR may be a promising surgical treatment to prevent postoperative lymphedema. There is a need for larger studies with longer follow-up to confirm the findings obtained in our study.
RESUMO
BACKGROUND/AIMS: We conducted a nationwide population-based study to investigate incidence rates of colorectal and biliary cancers according to accompanying primary sclerosing cholangitis in Korean ulcerative colitis patients. METHODS: We used the Health Insurance Review and Assessment claim database from January 2007 to April 2020. Standardized incidence ratios of colorectal and biliary cancers in ulcerative colitis patients were calculated. RESULTS: Among 35,189 newly diagnosed ulcerative colitis patients, 1,224 patients were diagnosed with primary sclerosing cholangitis. During the study period, 122 and 52 patients were diagnosed with colorectal and biliary cancers, respectively. Incidences of colorectal cancer were not higher in ulcerative colitis patients than those in the general population (standardized incidence ratios, 0.83; 95% confidence interval, 0.69-0.99), regardless of accompanied primary sclerosing cholangitis (standardized incidence ratio, 0.73; 95% confidence interval, 0.24-1.71). While incidences of biliary cancer were not higher in ulcerative colitis patients than those in the general population (standardized incidence ratio, 1.14; 95% confidence interval, 0.80-1.58), these were much higher with accompanied primary sclerosing cholangitis (standardized incidence ratio, 10.07; 95% confidence interval, 5.75-16.36). Cumulative incidences of colorectal and biliary cancers increased in patients who were diagnosed with ulcerative colitis at an older age. CONCLUSIONS: In Korean ulcerative colitis patients, colorectal cancer incidences were not higher than those in the general population regardless of accompanied primary sclerosing cholangitis. However, biliary cancer incidences were much higher in ulcerative colitis patients with primary sclerosing cholangitis than in those without, or in the general population.
RESUMO
BACKGROUND: Robotic reconstructive surgery has been performed since 2012 at our institution. The purpose of this study was to report our 10-year experience with robot-assisted reconstructive surgery and compare the clinical outcomes of different robotic models. METHODS: Medical records of 41 patients who had chest or breast reconstruction during October 2012 â¼ May 2021 were reviewed retrospectively. Different robotic models were evaluated and compared in terms of surgical technique, demographic variables, postoperative complication, and operative parameters. esthetic assessments were performed by four plastic surgeons to evaluate symmetry, scar formation, and general esthetic features based on patients' photographs. RESULTS: Overall, out of 41 robot-assisted reconstructive surgeries, 13 were performed with the Da Vinci Si model, 18 with the Da Vinci Xi model, and 10 with the Da Vinci Sp model. The docking time, robot operation time, and hospitalization time were shorter for surgeries, which used the Da Vinci Sp model than other models. All other complications and operative parameters showed no significant difference. Improved esthetic outcome was achieved for all patient groups. Group Sp had the most favorable score, followed by Group Xi and Group Si, although there were no statistical implications. CONCLUSIONS: Ever since the introduction of the Da Vinci model in 2012, we have successfully implemented the robot-assisted reconstructive surgery. Surgical technique improved over the last 10 years. With the introduction of the Sp model, we are now at the stage of further developing the surgical technique and establishing the robotic reconstructive surgery.

Currently, robot-assisted latissimus dorsi muscle flap (RLDF) surgery is used in treating patients with Poland syndrome and for breast reconstruction. However, conventional RLDF surgery has several inherent issues. We resolved the existing problems of the conventional system by introducing the da Vinci single-port system in patients with Poland syndrome. Overall, three patients underwent RLDF surgery using the da Vinci single-port system with gas insufflation. In the female patient, after performing RLDF with silicone implant, augmentation mammoplasty was also performed on the contralateral side. Both surgeries were performed as single-port robotic-assisted surgery through the transaxillary approach. The mean operating time was 449 (335-480) minutes; 8.67 (4-14) minutes were required for docking and 59 (52-67) minutes for robotic dissection and LD harvesting. No patients had perioperative complication and postoperative problems related to gas inflation. The single-port robot-assisted surgical system overcomes the drawbacks of previous robotic surgery in patients with Poland syndrome, significantly shortens the procedure time of robotic surgery, has superior cosmetic outcomes in a surgical scar, and improves the operator's convenience. Furthermore, concurrent application to another surgery demonstrates the possibility in the broad application of the robotic single-port surgical system.
RESUMO
Colorectal cancer is a common cancer; generally, adults aged ≥ 50 years are screened using stool occult blood tests and colonoscopy. However, colorectal adenoma and cancer have been found in patients under the aged of 50, and studies on characteristics and risk factors in young patients are lacking. We evaluated the prevalence and risk factors of colorectal adenoma and cancer in young adults aged under 50 years. We retrospectively analyzed 570 individuals aged under 50 years who underwent colonoscopy at the Haeundae Paik Hospital, Korea, from January to June 2018. Logistic regression model was used to identify the risk factors for colorectal adenoma and colorectal cancer. The prevalence of colorectal adenoma in group of 19-29 years was 3.2% (1 of 31), 30-39 years was 13.8% (30 of 217) and in the group of 40-49 years was 21.1% (68 of 322) (P = .009). In multivariable analysis, age over 45 years (adjusted odds ratio [OR], 1.941; 95% confidence interval [CI], 1.187-3.172; P = .008) and male sex (adjusted OR, 1.711; 95% CI, 1.044-2.806; P = .033) were independent risk factors for colorectal neoplasia including cancer. The prevalence of colorectal adenoma increases as the age increased in young adults under 50 years of age, especially after the age of 45 years, the risk of colorectal neoplasia increases; hence, early screening should be considered before the age of 50 years.

BACKGROUND: Currently, a variety of treatment modalities are implemented for breast reconstruction. However, clinical prognosis regarding sensory regeneration of the breast and patient-reported satisfaction remains underexamined. In this study, we aimed to compare breast sensibility after various reconstruction. METHODS: We conducted a retrospective comparative study of all patients who underwent breast reconstruction between August 2016 and October 2019 at our institution. Acellular dermal matrixes were used to cover the implant inferolaterally in a dual-plane subpectoral approach and to wrap the implant in prepectoral direct to implant (DTI). The cutaneous tactile pressure threshold and patient satisfaction outcome were tested. RESULTS: A total of 105 breasts were assessed, 30 breasts reconstructed with deep inferior epigastric perforator (DIEP) flap, 40 breasts reconstructed with 2-stage subpectoral implant, and 35 breasts reconstructed with prepectoral DTI. In the specific group-to-group analysis, DIEP and implant groups showed significant differences in sensory recovery, mainly in lateral areas of the reconstructed breast. In 2-stage reconstruction and DTI groups, there were no statistically significant differences. When comparing patient groups using only patients with follow-up lengths of more than 12 months, the difference was more clearly indicated (P = 0.049). Better sensory recovery predicted high satisfaction scores in patient-reported outcomes (P = 0.007). CONCLUSIONS: We found that subpectoral implant reconstruction and DTI show no statistically significant differences in sensory recovery, and autologous DIEP flap reconstruction results in a better prognosis than prosthesis implant reconstruction. Furthermore, the clarity of the differences increased when the follow-up length was longer than 12 months. Better patient-reported satisfaction was associated with good breast sensibility.

BACKGROUND: Adjuvant computed tomography-based conformal electron beam radiation therapy (RT) for patients with keloids enables radiation oncologists to customize the target volume with precision and deliver the maximal prescription dose while sparing normal surrounding tissues. OBJECTIVE: To report treatment and cosmetic outcomes by the patient's self-assessment survey. METHODS: Medical records of patients with keloids, who were treated with postoperative electron beam RT between January 2015 and December 2020, were reviewed. A total of 85 consecutive patients with 136 keloids were included in this study. Subjective cosmetic outcomes were scored by each patient using a 5-point Likert scale survey. RESULTS: The median follow-up time was 29.0 months (range, 12.1-77.9 months), and local recurrence was observed in 10 lesions (7.4%). The recurrence rate of keloids occurring in the ear was 5.4%, whereas the recurrence rate of keloids occurring at other body sites was 11.4%. Among the patients who responded to the questionnaire about the cosmetic outcome, 70.2% of patients declared being either very satisfied (44.7%) or satisfied (25.5%). CONCLUSION: Surgical excision, followed by CT-based conformal electron beam RT, for patients with keloids ensures a high degree of local control resulting in good cosmetic outcomes.

BACKGROUND: The occurrence of thyroid cancer has increased dramatically, and postoperative scars are placed at easily visible locations. Many patients show stronger desire for scar prevention. So far, numerous approaches have been discussed for the treatment of scars; this study is conducted to verify whether the early application of combined therapy contributes to minimal scar formation. METHODS: Between March 2019 and December 2019, total of 64 patients with thyroidectomy scars of a size greater than 4.5 cm located on the anterior neck were enrolled in this prospective pilot study. Subjective and objective evaluation were carried out using the Patient and Observer Scar Assessment Scale (POSAS) at one, two, and six months after operation. Results were compared between a treatment group and a non-treatment group. RESULTS: In PSAS score, the mean values of pain, itching sensation, pliability, thickness, and relief were significantly higher in the laser and steroid treatment group (p = 0.009, p = 0.000, p = 0.013, p = 0.002, and p = 0.007). The value of color of the scars showed no significant differences (p = 0.504). In OSAS score, parameter of thickness, relief, and surface area score was significantly higher score in the combination group (p = 0.029, 0.035, and 0.020), while vascularity, pigmentation, and pliability were not significantly different between two groups (p = 0.548, p = 0.983, and p = 0.128). CONCLUSION: This study demonstrates that early combination therapy contributes to scar improvement to a meaningful extent based on POSAS. We believe that the combined therapy has a synergy effect on scar management, which improves the patients' quality of life in relation to their postoperative scars.

BACKGROUND: Vascularized lymph node transfer (VLNT) is a well-established surgical approach for treating lower extremity lymphedema (LEL). Since VLNT takes time to show effect, a combined approach with lymphaticovenular anastomosis (LVA) may be more advantageous to patients by inducing an immediate improvement. This study aims to describe our experience and evaluate the results of a combined approach. METHODS: In this retrospective review, we analyzed a total of 12 patients that underwent simultaneous supraclavicular VLNT and LVA for the treatment of secondary LEL with the ISL stage II or III. Patients who had a follow-up period of less than 12 months were excluded. The supraclavicular flap, including superficial lymphoid tissue as well as deep cervical nodes, was harvested and anastomosed to the posterior tibial vessels. The pre- and postoperative change of circumference difference ratios and LEL index were compared. RESULTS: All twelve flaps survived without re-exploration. An average of 2.3 LVAs were simultaneously performed. At 12.9 months of follow-up (range, 12-16 months), the postoperative mean circumference ratio was significantly improved than pre-operative in 10 cm above the knee (7.9 ± 7.2% vs 15.0 ± 7.6%, p = 0.01), 10 cm below the knee (8.5 ± 7.5% vs 17.4 ± 12.7%, p = 0.03) and lateral malleolus (16.5 ± 15.5% vs 28.6 ± 17.9%, p = 0.03). Also, the mean LEL index was decreased (preoperative 324.3 ± 53.0 vs postoperative 298.0 ± 44.6, p = 0.242) and eight patients showed improvement in LEL stage. CONCLUSIONS: The combined approach showed a significant decrease in the circumference of LEL. Additional LVAs could reinforce the effect of a VLNT. Larger series with longer follow-up is needed to confirm our findings.
