    Abstract Perforator flaps can be raised anywhere in the body, with minimal donor-site deformity, and can be made into custom-made combined composite flaps, especially for severe complex defects such as osteomyelitis of the lower limbs. Here, we report on the representative application of the combined tissue transfers for complex leg defects. For a wide range of complex defects in the lower extremity, it is necessary to perform reliable revascularization by bypass or flow-through type or vein graft. At the same time, a chimeric or "Orochi" type combined transfer using a minimally invasive perforator flaps and a well-vascularized bone flap are useful. In the case of nerve palsy, it could be possible to combine vascularized nerve flaps. Combined tissue transfers with less invasive donor will be more available in the future.

    Abstract This single-centre retrospective cohort study aimed to clarify the superiority of treatment by comparing the outcomes of lymphaticovenular anastomosis with compression therapy and conservative treatment centred on compression therapy in the early stage of breast cancer-related lymphoedema. Data were collected from all patients treated for breast cancer-related lymphoedema between January 2015 and December 2022. The patients were classified into conservative treatment and surgical treatment groups. The upper extremity lymphoedema index value was calculated, based on five circumference values of the upper extremity and body mass index, to compare the 6-, 12-, 18- and 24-month outcomes between the groups. Of 101 patients with breast cancer-related lymphoedema, 81 (conservative treatment: 52; surgical treatment: 29) were included in the analysis. The therapeutic effect was significantly higher in the surgical treatment group than in the conservative treatment group, when comparing the rate of change in oedema at 6 (-6.6% ± 7.3% vs. 0.9% ± 7.5%; p < 0.001), 12 (-7.3% ± 6.2% vs. 2.9% ± 8.6%; p < 0.001), 18 (-7.6% ± 8.0% vs. 3.9% ± 9.2%; p < 0.001) and 24 (-5.6% ± 6.0% vs. 4.4% ± 10.7%; p < 0.001) months. The incidence of cellulitis increased in the conservative treatment group (from 9.6% to 15.4%), whereas it was suppressed in the surgical treatment group (from 13.8% to 0%). Conservative treatment centred on compression therapy increased oedema over time; however, lymphaticovenular anastomosis with compression therapy effectively reduced oedema.

    Abstract Objective: Several options for the treatment of lower extremity lymphedema (LEL) can be broadly classified into conservative treatment, such as compression garments and decongestive lymphatic therapy, and surgical treatment, such as lymphaticovenular anastomosis (LVA). The purpose of our study was to clarify the superiority of these treatments by comparing the outcomes of LVA with those of conservative treatment for early-stage LEL.
    Methods: We performed a single-center, retrospective cohort study. The patients with LEL who presented to our department between January 2015 and December 2022 were identified and classified into two groups: conservative treatment and surgical treatment. The LEL indexes, calculated from the four lower extremity circumferences and the body mass index, were compared at the 6-, 12-, and 24-month follow-up between the two groups.
    Results: Of the 101 patients with LEL, 53 with 72 affected limbs (conservative treatment, 39 patients and 53 affected limbs; surgical treatment, 15 patients and 19 affected limbs) were included in the present analysis. The therapeutic effect for reducing edema, as determined by comparing the corrected LEL index at 12 months (103.7 ± 12.7 vs 91.9 ± 10.7; P = .005) and 24 months (103.1 ± 12.9 vs 83.8 ± 7.2; P < .001), was significantly higher in the surgical treatment group than that in the conservative treatment group. The conservative treatment group showed little change in the corrected LEL index at ≤24 months of follow-up (+3.1%; P = .299). In contrast, the surgical treatment group showed a significant reduction in edema at 24 months according to the corrected LEL index (-16.2%; P = .019).
    Conclusions: In early-stage LEL, conservative treatment centered on compression therapy alone only maintained edema (ie, edema did not worsen or improve). In contrast, LVA with compression therapy reduced edema.

    Abstract Introduction: MTX-LPD is a complication that occurs during MTX treatment. Skin lesions in MTX-LPD are often subcutaneous nodules with occasional necrosis and ulceration. Although MTX-LPD regression is frequently observed upon discontinuation of oral MTX treatment, delayed diagnosis of MTX-LPD with associated ulceration may lead to ulcer enlargement and the need for surgical procedures such as skin grafts.
    Case report: A 74-year-old female was diagnosed with RA and administered MTX for 3 years and 8 months. The patient presented with a 2-month-old ulcer on the dorsum of the hand. The ulcer size was 6.5 cm × 5 cm, and it was surrounded by an embankment tumor measuring 7 cm × 6 cm. Although a definitive diagnosis could not be made based on the biopsy specimen, excision of the ulcer-containing mass confirmed MTX-LPD diagnosis. MTX was discontinued, and free-flap reconstruction was performed 3 weeks after the first surgery. The postoperative period was uneventful, and MTX-LPD recurrence was not observed 10 months after the second surgery.
    Conclusion: Although MTX-LPD with ulceration is rare, it should be considered in cases of refractory ulcers in patients with RA. The discontinuation of MTX based on early MTX-LPD diagnosis is critical to avoid surgical procedures such as skin grafts and flap reconstruction.

    Abstract This case series aimed to investigate the result of venous end-to-side (ETS) anastomosis in the extremities to contribute to a meta-analysis to evaluate the postoperative complications of venous ETS anastomosis in the extremities. This was a single-center case series and meta-analysis of patients who underwent venous ETS anastomosis for free-flap reconstruction of the extremities. We reviewed the records of 41 free flaps in 40 patients and performed a comprehensive search of PubMed, Scopus, and Web of Science for studies published from inception to December 2022. Primary outcomes were venous thrombosis, takebacks, and total and partial flap failures. Complication rates and confidence intervals were calculated using a random-effects model. In our case series, four (12.2%) patients with five flaps were taken back to the operating room, three (7.3%) flaps were due to venous thrombosis, and three (7.3%) flaps ultimately resulted in total flap failure. Our meta-analysis demonstrated the following complication rates: 4.0% (95% confidence interval [CI], 0-18.1%; I
