RESUMO
We demonstrated local intravenous heparin infusion to salvage flaps after re-exploration for postoperative venous congestion after free-flap breast reconstruction. All flaps were salvaged using local intravenous heparin infusion without major complications. Local intravenous heparin infusion is an effective and safe procedure.
RESUMO
BACKGROUND: There is no consensus on the postoperative outcomes of tongue reconstruction. Therefore, the authors developed a novel risk model for predicting dysphagia after tongue reconstruction. METHODS: This retrospective study was conducted by the Oral Pharyngeal Esophageal Operation and Reconstruction Analytical, or OPERA, group across 31 cancer centers and university hospitals in Japan. A total of 532 patients [390 (73.3%) men and 142 (26.7%) women; median age at surgery, 60 years (range, 15 to 88 years)] who were diagnosed with oral tongue squamous cell carcinoma and underwent tongue reconstruction following glossectomy between 2009 and 2013 were included. Independent risk factors were identified using univariate regression analysis and converted to a binary format for multivariate analysis. An integer value was assigned to each risk factor to calculate a total score capable of quantifying the risk of feeding tube dependence. RESULTS: Overall, 54 patients (10.2%) required a feeding tube at the time of evaluation. Predictive factors for feeding tube dependence were advanced age, lower American Society of Anesthesiologists physical status, low body mass index, lower serum albumin, comorbid hypertension and diabetes, extended tongue defect, resection beyond the tongue, laryngeal suspension, postoperative radiation therapy, and no functional teeth. In multivariate logistic regression analysis, age greater than or equal to 58.5 years, postoperative radiation therapy, wider tongue defect, and body mass index less than 21.27 kg/m 2 earned 6, 4, 3, and 2 points, respectively, for a maximum total score of 15. CONCLUSION: The authors' risk model provides a mathematical tool for estimating the individual risk of postoperative feeding tube dependence before tongue reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Free tissue transfer has been frequently used in head and neck reconstruction. However, vascular problems still cause serious damage to patients when thromboses occur in microvascular anastomoses. In the Gemini anastomosis procedure, two flap pedicle veins are anastomosed adjacently to the internal jugular vein using the end-to-side anastomosis method. From April 2019 to March 2021, 12 patients whose free flaps had two pedicle veins underwent head and neck surgery in Saitama Cancer Center (Saitama, Japan). In six patients, the veins were anastomosed adjacently to the internal jugular vein using the Gemini procedure (Gemini group). In the other six patients, the veins were anastomosed to the internal jugular vein using the end-to-side anastomosis method at a distance from each other (control group). The anastomosis time was measured retrospectively by reviewing video from the operations and comparing them across groups. There were no reoperations in any patients, and all flaps survived without exhibiting any circulatory problems. The mean total anastomosis time in the Gemini group was 21 minutes 38 seconds ± 75 seconds. The mean total anastomosis time in the control group was 34 minutes 14 seconds ± 121 seconds. The mean flap ischemic time in the Gemini group was 124 minutes ± 3 minutes. The mean flap ischemic time in the control group was 135 minutes ± 6 minutes. The Gemini anastomosis procedure is effective and convenient when the pedicle has two veins and the recipient vein choice is only the internal jugular vein in head and neck reconstruction.
RESUMO
OBJECTIVE: The thyroid gland adjoins the trachea, pharynx, esophagus, carotid artery and cervical skin. Most thyroid carcinomas have been treated at lower stages; however, in some cases the carcinomas have invaded the surrounding organs. After resecting invasive thyroid carcinomas, the defects vary depending on the invasion area and organs affected; subsequent reconstructive methods vary depending on the size of defect and its components. This study analysed the pattern of defects and the reconstructive methods used following invasive thyroid carcinoma resection. METHODS: From April 2011 to March 2021, 665 patients in Saitama Cancer Center (Saitama, Japan) were diagnosed with thyroid carcinoma and subsequently underwent thyroidectomies. In the 25 patients (3.8%), the thyroid carcinoma invaded surrounding organs and any reconstructive surgery-including end-to-end tracheal anastomosis and simple pharynx closure-was performed after thyroid carcinoma resection. The patients' records were retrospectively reviewed, and the defects and subsequent reconstructive methods were analysed. RESULTS: When our new classification system was applied to the defects, the number of cases for each type was totaled: Tr0: 1; Tr1a: 3; Tr2b: 5; Tr3a: 1; La-Tr3b+PE2: 7; La-Tr3b+PE2+S2: 1; PE1: 1; PE1+S1: 2; S1: 2; S2: 2. For Tr0, a tracheal fenestration was performed after the tumor resection and the fenestration was closed with a hinge flap. For Tr1a defect, a tracheal fenestration was performed with cervical skin after the tumor resection and the tracheal fenestration was closed with a deltopectoral flap or pectralis major musculocutaneous flap. In one recent patient, the tracheal fenestration was reconstructed using free forearm flap and cervical skin, and the fenestration was closed with a hinge flap. For Tr2b defect, free forearm flap and costal cartilage graft reconstruction was performed after the tumor resection and the fenestration was closed with a hinge flap. For Tr3a defect, end-to-end anastomosis was performed in one patient. For La-Tr3b+PE2 defect, total pharyngolaryngectomy with free jejunal flap reconstruction was performed. For PE1 defect, a simple closure was performed in one patient and a PMMC muscle flap was used for covering the suture line in two patients. For S1 and S2 defect, PMMC flap or DP flap was used. CONCLUSION: Our analysis of defects and reconstructive methods defines the complex defect patterns occurring after invasive thyroid carcinoma resection, describes the patterns of subsequent reconstructive methods.

BACKGROUND: In patients undergoing mastectomy for locally advanced breast cancer (LABC), surgical skin flap reconstruction is sometimes required in order to cover large skin defects. This study assessed the efficacy of local, cutaneous (rhomboid) flap reconstruction after mastectomy by comparing data from patients with LABC requiring local flap reconstruction after mastectomy and those that underwent mastectomy alone. METHODS: Data from 68 patients with LABC who underwent mastectomy were reviewed retrospectively; 14 underwent local (rhomboid) flap reconstruction after mastectomy (local flap group) and 54 underwent direct closure after mastectomy (direct closure group). A pinch test was performed to determine the closure method. Data on the operation, postoperative complications, and postoperative quality of life (QOL) were compared between groups. RESULTS: It was possible to close defects in the local flap group that were significantly larger than those in the direct closure group (p=0.0002). There was no significant difference in postoperative complications between groups. Although operative duration was significantly longer in the local flap group than in the direct closure group (p=0.016), the average difference was only 25 minutes. There was no significant difference in variables related to postoperative QOL. CONCLUSIONS: Rhomboid flap reconstruction was effective for covering large defects after mastectomy in patients with LABC.

Head and neck cancer metastasizing to the small intestine is very rare. Here we report a case of cancer of the mandibular gingiva metastasizing to the small intestine. The patient was an 82-year-old man who had squamous cell carcinoma of the mandibular gingiva staged as T2N2bM0. Two months after surgery, he presented with lower abdominal pain accompanied by signs of peritoneal irritation. Urgent abdominal surgery was performed, during which a crater-shaped perforation was noted on the wall of the ileum. Microscopic findings at this site confirmed a diagnosis of metastatic squamous cell carcinoma in the small intestine from the mandibular gingiva. To our knowledge, this is the first case report of oral cancer metastasizing to the small intestine. If gastrointestinal symptoms appear in a patient with advanced oral cancer, a differential diagnosis of metastasis to the gastrointestinal tract should be kept in mind.

PURPOSE: To prevent tissue expander (TE) exposure following mastectomy flap necrosis in immediate breast reconstruction, the TE is usually covered completely or partially with a musculofascial (MF) flap. This study compares the complications of the two coverage methods. METHODS: We reviewed, retrospectively, 106 cases of immediate TE-based breast reconstruction. The patients were divided into two groups according to whether complete or partial TE coverage was done. In the complete coverage group, the serratus anterior MF flap was dissected and sutured to the pectoralis major muscle to cover the TE completely. In the partial coverage group, the serratus anterior MF flap was not dissected, and the lateral border of the pectoralis major muscle was sutured to the mastectomy skin flaps. RESULTS: The TEs were covered completely in 60 breasts and partially in 46 breasts. The mastectomy flap necrosis rate was significantly higher in the complete coverage group (p < 0.01), but there was no incidence of TE exposure in either groups. The lateral migration rate was significantly higher in the partial coverage group (p = 0.033). There were no significant differences in the cranial migration rate (p = 0.133). CONCLUSIONS: The complete coverage method is a better option if there is a high risk of mastectomy flap necrosis; however, surgeons should monitor carefully for cranial migration.

Differentiated thyroid carcinoma is not highly malignant, and thus surgical resection is the most common treatment even if the carcinoma has invaded the trachea. Although some cases exist in which the carcinoma invades the trachea, using the tracheal window resection method allows complete resection of the carcinoma. Yet these patients must often control a large tracheocutaneous wound until reconstructive surgery is performed because such surgery occurs secondarily. Our hospital admitted three patients for which tracheally invasive, differentiated thyroid carcinoma was surgically resected. Tracheal defects of 1/2 to 2/3 of the tracheal circumference were reconstructed primarily using the free forearm flap and costal cartilage during carcinoma resection. Following surgery, only a small tracheocutaneous fistula remained open, which was closed at about three months post-operation. The reconstructed tracheal space and transferred costal cartilage thickness were monitored by CT scan imaging at about 12 months post-operation. Details of the reconstructive method and postoperative changes in the reconstructed trachea and thickness of the costal cartilage are described in this report.

BACKGROUND: Free jejunal transfer has a high success rate, but if vascular thrombosis occurs, the salvage of failing flap with reanastomosis is difficult. This study described a combined deltopectoral (DP) and pectoralis major musculocutaneous (PMMC) flap 2-step technique for cervical esophageal reconstruction after free-jejunal-flap necrosis. METHODS: In step 1, the detection of free jejunal flap with the subsequent debridement of necrotic and infected tissue was followed by the construction of external fistula on the pharyngeal side with the hole in cervical skin and the construction of another external fistula on the esophageal side and tracheal stoma with a single or double DP flap. In step 2, after the primary healing of all wounds was confirmed, a wide hinge flap was elevated for reconstructing the posterior wall or full circumferential defect of cervical esophagus. PMMC flap harvested from either the left or right anterior chest wall was used for reconstructing the cervical surface defect or anterior pharyngeal wall. RESULTS: This technique was used for cervical esophageal reconstruction after free-jejunal-flap necrosis in 5 patients. Step 1 surgery was performed at an average of 10 days after primary-free-jejunal flap transfer. Oral intake was resumed in all cases at an average of 117 days after step 2 surgery. No complications including esophageal stricture were found during a 6-month follow-up period. CONCLUSIONS: Combined DP and PMMC flap technique was useful for cervical esophageal reconstruction after free-jejunal-flap necrosis and applicable to patients with the late detection of jejunal necrosis and surgical-site infection.
RESUMO
BACKGROUND: Lymphatic malformations (LMs) are low-flow congenital lesions that consist of cysts of varying size. Sclerotherapy with intralesional bleomycin and OK-432 has been reported to yield dramatically beneficial results for this disorder. However, inflammation-related symptoms are often seen after treatment with these sclerosing agents. On the other hand, polidocanol (POL) is reportedly associated with fewer allergic and inflammatory reactions. Up to now, however, very few reports have documented the use of POL microfoam for treatment of LMs. This study was performed to assess the efficacy and safety of POL microfoam sclerotherapy for LMs. METHODS: Between 2003 and 2016, cases were identified from a prospectively compiled database on low-flow congenital vascular malformations before undertaking a retrospective electronic chart review. Patients were included if they had LMs that had been treated by POL microfoam sclerotherapy. The location, size, and type of LMs were assessed using ultrasound and magnetic resonance imaging. Twenty-gauge venous catheters were inserted into the lymphatic space under ultrasound visualization. The LMs were then fully aspirated if they were macrocystic in form. Microfoam composed of 3% POL was then injected under ultrasound guidance. Microcystic LMs were treated by direct injection with POL microfoam under ultrasound guidance. The outcome was assessed by clinical examination combined with findings of postsclerotherapy imaging using ultrasound and magnetic resonance imaging. RESULTS: During a 13-year period, 32 patients met the inclusion criteria. These were 11 (34%) male patients and 21 (66%) female patients with a mean age of 18 years. The LMs were localized to the head and neck (47%), the trunk (38%), and the extremities (15%). The lesions were subdivided into macrocystic (56%), mixed macrocystic and microcystic (31%), and microcystic (13%) LMs. The average lesion size was 6.6 × 4.6 × 3.0 cm. The mean number of treatment sessions was 2.8 (range, 1-15), with a mean foam volume of 4.6 (range, 1-10) mL. Excellent (47%) and moderate (41%) responses were seen in 88% of the patients. Notably, half of the patients achieved excellent or moderate resolution with a single treatment session. Intralesional hemorrhage occurred in four patients (13%) but resolved spontaneously. Only one patient with mixed macrocystic and microcystic LMs developed post-therapy infection. However, the other patients did not develop any post-therapy inflammation-related symptoms, including fever, pain, and marked swelling. CONCLUSIONS: Percutaneous sclerotherapy using POL microfoam appears to be safe and effective for treatment of LMs. Ultrasound-guided POL microfoam sclerotherapy should be considered for such lesions, particularly those that are exclusively macrocystic.

Resection for locally advanced breast cancer (LABC) or malignant phyllodes tumors may cause a large skin defect with bone exposure. Although skin grafts are frequently used to cover such defects, they can result in poor cosmetic outcomes and graft acceptance is dependent upon the condition of the recipient site. To overcome the limitations of skin grafts, various flaps have been developed to cover such defects. The present study used a rhomboid flap for the coverage of skin defects after mastectomy and breast-conservative surgery (BCS). A total of 11 patients with malignant breast cancer underwent reconstructive surgery using the rhomboid flap between September 2011 and December 2013 (mastectomy, 9 patients; BCS, 2 patients). Skin resection size, axillary lymph node dissection, bone exposure, length of surgery, wound complications and whether preoperative/postoperative adjuvant therapy was received were analyzed. The maximum size of skin defect covered with the rhomboid flap in the present study was 20×20 cm. There were no major wound complications and all patients underwent postoperative adjuvant therapy on schedule. During BCS, a portion of the flap was used for augmentation of the breast, in addition to coverage of the skin defect, which resulted in good cosmetic outcomes. The rhomboid flap can be quickly and easily fashioned, and it does not require any special instruments.
RESUMO
Background Breast reconstruction is associated with multiple risk factors for venous thromboembolism. However, the incidence of deep vein thrombosis in patients undergoing breast reconstruction is uncertain. Objective The aim of this study was to prospectively evaluate the incidence of deep vein thrombosis in patients undergoing breast reconstruction using autologous tissue transfer and to identify potential risk factors for deep vein thrombosis. Methods Thirty-five patients undergoing breast reconstruction were enrolled. We measured patients' preoperative characteristics including age, body mass index (kg/m2), and risk factors for deep vein thrombosis. The preoperative diameter of each venous segment in the deep veins was measured using duplex ultrasound. All patients received intermittent pneumatic pump and elastic compression stockings for postoperative thromboprophylaxis. Results Among the 35 patients evaluated, 11 (31.4%) were found to have deep vein thrombosis postoperatively, and one patient was found to have pulmonary embolism postoperatively. All instances of deep vein thrombosis developed in the calf and were asymptomatic. Ten of 11 patients underwent free flap transfer, and the remaining one patient received a latissimus dorsi pedicled flap. Deep vein thrombosis incidence did not significantly differ between patients with a free flap or pedicled flap (P = 0.13). Documented risk factors for deep vein thrombosis demonstrated no significant differences between patients with and without deep vein thrombosis. The diameter of the common femoral vein was significantly larger in patients who developed postoperative deep vein thrombosis than in those who did not ( P < 0.05). Conclusions The morbidity of deep vein thrombosis in patients who underwent breast reconstruction using autologous tissue transfer was relatively high. Since only the diameter of the common femoral vein was predictive of developing postoperative deep vein thrombosis, postoperative pharmacological thromboprophylaxis should be considered for all patients undergoing breast reconstruction regardless of operative procedure.

Background For soft palate defects of more than two-thirds, we previously described the bent anterolateral thigh (ALT) method in which the pharyngeal isthmus was reconstructed as a tunnel structure. In this study, we compared the new "tunnel structure" reconstruction in our bent ALT flap method and the traditional "port structure" reconstruction. Methods From April 2010 to March 2015, 25 patients in Saitama Cancer Center (Saitama, Japan) underwent oropharyngeal tumor resection including soft palate resection. In patients who had soft palate resection of less than two-thirds, the Gehanno method was performed in 10 patients (the data were shown as a comparison). In patients who had soft palate resection of more than two-thirds, the pharyngeal isthmus was reconstructed as a tunnel structure using the bent ALT flap method in eight patients and as a port structure in seven patients. The functional outcomes were assessed by interviewing patients about their symptoms and measuring the standard articulation test. Results Postoperative function was favorably maintained at equal levels in the tunnel structure reconstruction group and the Gehanno method group at approximately 12 months postoperation. However, in most patients in the port structure reconstruction group, the pharyngeal isthmus became larger after 12 months postoperation and the articulation test was significantly worse than the Gehanno group and the tunnel group. Conclusion The bent ALT flap method had superior results to the conventional method. Thus the pharyngeal isthmus should be reconstructed as a tunnel structure for patients with soft palate defects of more than two-thirds.

BACKGROUND: Near-infrared spectroscopy (NIRS) allows continuous noninvasive monitoring of changes in the tissue levels of oxygenated hemoglobin (O2Hb) and deoxygenated hemoglobin (HHb) and can identify the severity of chronic venous diseases. Here we investigated the predictors of post-thrombotic syndrome (PTS) using NIRS in patients with a first episode of deep venous thrombosis (DVT). METHODS: The study enrolled 129 patients with DVT. Risk factors in each patient were assessed at presentation. Venous abnormalities confirmed by ultrasound and parameters derived from NIRS were evaluated at 6 months after DVT. On standing, increases in O2Hb and HHb (ΔO2Hbst and ΔHHbst) and the times taken for each concentration to become maximal (TO2Hbst, and THHbst) were measured. During 10 tiptoe movements, O2Hb showed a continuous decrease (ΔO2Hbex), whereas venous expulsion (ΔHHbEex) and subsequent retention (ΔHHbRex) were observed. The oxygenation index (HbD; HbD = O2Hb - HHb) was also calculated at the end of standing and at the end of 10 tiptoe movements (ΔHbDst and ΔHbDex). Final clinical manifestations were evaluated at 6 years, and PTS was considered to be present if the Villalta score was ≥5. RESULTS: Thirteen patients were excluded and 116 patients were finally included. Of these, 19 (16%) developed PTS. Among various NIRS-derived parameters, TO2Hbst had the highest area under the curve (0.88; 95% confidence interval [CI], 0.80-0.93; P < .01) with the best cutoff value (TO2Hbst ≤48 seconds). On univariate analysis, variables associated with greater risk for development of PTS were stroke (odds ratio [OR], 5.59; 95% CI, 0.74-42.41; P = .06), idiopathic DVT (OR, 4.13; 95% CI, 1.36-12.55; P < .01) and iliofemoral DVT (OR, 4.31; 95% CI, 1.48-12.60; P < .01) at initial presentation, venous occlusion combined with reflux (OR, 4.24; 95% CI, 1.50-12.00; P < .01), and NIRS-derived TO2Hbst ≤48 seconds (OR, 43.03; 95% CI, 9.04-204.81; P < .01) at 6 months. Multivariate logistic regression analysis finally revealed venous occlusion combined with reflux (OR, 4.80; 95% CI, 1.03-22.36; P < .05) and NIRS-derived TO2Hbst ≤48 seconds (OR, 53.73; 95% CI, 8.43-342.41; P < .01) to be independently associated with PTS progression. CONCLUSIONS: NIRS-derived TO2Hbst ≤48 seconds is a promising time-course predictor of PTS progression.

Two cases of successful primary closure of a bronchopleural fistula with favorable infection control using latissimus dorsi musculocutaneous flaps are reported. Case 1 was a 70-year-old man who underwent resection of the right lower pulmonary lobe due to right lung metastasis of sigmoid colon cancer. A bronchopleural fistula was found on day 28 after surgery. Infection was controlled by antibiotic administration and tube drainage. Closure of the bronchopleural stump, thoracoplasty and plombage of latissimus dorsi muscles were performed for single-stage closure without open treatment, based on a negative pleural effusion culture. Case 2 was a 64-year-old man who underwent right lower pulmonary lobe resection due to right lung cancer. A bronchopleural fistula was found on day 14 after surgery. In single-stage closure, thoracoplasty and plombage of latissimus dorsi muscles were performed due to infection control and a negative pleural effusion culture. Both cases had a good postoperative course.

BACKGROUND: Various studies have indicated a worldwide increase in the number of immediate breast reconstruction surgeries. However, breast reconstruction should not delay or prevent postoperative cancer therapeutics such as adjuvant chemotherapy and radiotherapy. In response to these developments, our team researched the impact of immediate breast reconstruction on postoperative adjuvant chemotherapy. METHODS: From April 2006 to March 2011, 116 patients at Saitama Cancer Center underwent postoperative adjuvant chemotherapy following mastectomy with or without immediate breast reconstruction. Fifty patients received postoperative adjuvant chemotherapy following mastectomy with immediate breast reconstruction (IBR group), and 66 patients received the same treatment but without immediate breast reconstruction (non-IBR group). The outcomes were studied retrospectively by chart review. Patients' average age, body mass index, postoperative complication rate, and days to adjuvant chemotherapy were calculated. RESULTS: Mean age and body mass index of patients were 47.0 ± 9.0 years, 22.2 ± 3.0 kg/m(2) and 55.5 ± 10.1 years, 23.0 ± 3.6 kg/m(2) in IBR group and non-IBR group, respectively. Postoperative complication rate was 10.0 % in IBR group and 6.1 % in non-IBR group. Days to adjuvant chemotherapy was 61.0 ± 10.5 days in IBR group and 58.0 ± 12.3 days in non-IBR group. CONCLUSIONS: Although complication rate and days to adjuvant chemotherapy were slightly increased in IBR group, the delay was not critical to the initiation of adjuvant chemotherapy in these patient groups.

OBJECTIVE: Assessment of tongue function following tongue reconstruction is important to evaluate patient status. To assess tongue function in patients who had undergone tongue reconstruction, the surgical team used a simple, hand-held tongue pressure measurement device to measure tongue power. METHODS: Tongue power of 30 patients (25 males, 5 females; average age: 53.6±15.0 years) was calculated using a hand-held tongue pressure measurement device, six months postoperation. The defects were classified into minimal glossectomy (MG) (n=8), near-half partial glossectomy of the mobile tongue (PG) (n=5), hemi-glossectomy (HG) (n=4), more than half partial glossectomy of the mobile tongue (SG-MT) (n=7), and subtotal glossectomy (SG) (n=6). As seen in other tongue assessments, a simple articulatory test, food evaluation, and speech intelligibility assessment were also performed; resulting correlations were statistically calculated using tongue pressure values. RESULTS: The tongue pressure values were 94.0±14.5% in MG, 48.5±13.2(a) % in PG, 40.4±18.7(a) % in HG, 19.3±7.7(a,b) % in SG-MT, and 15.3±5.6(a,b) % in SG (a: <0.05 vs. MG, b: <0.05 vs. PG). The Pearson r was 0.77, 0.67, and 0.74 when correlated with simple articulatory test, food evaluation, and speech intelligibility assessment, respectively. CONCLUSION: Tongue pressure measurement in patients with tongue cancer resection and reconstruction facilitated determination of patients' tongue function status.

Fire victims often suffer from burn injury and concomitant inhalation trauma, the latter significantly contributing to the morbidity and mortality in these patients. Measurement of blood carboxyhemoglobin levels has been proposed as a diagnostic marker to verify and, perhaps, quantify the degree of lung injury following inhalation trauma. However, this correlation has not yet been sufficiently validated. A total of 77 chronically instrumented sheep received sham injury, smoke inhalation injury, or combined burn and inhalation trauma following an established protocol. Arterial carboxyhemoglobin concentrations were determined directly after injury and correlated to several clinical and histopathological determinants of lung injury that were detected 48 hours post-injury. The injury induced severe impairment of pulmonary gas exchange and increases in transvascular fluid flux, lung water content, and airway obstruction scores. No significant correlations were detected between initial carboxyhemoglobin levels and all measured clinical and histopathological determinants of lung injury. In conclusion, the amount of arterial carboxyhemoglobin concentration cannot predict the degree of lung injury at 48 hours after ovine burn and smoke inhalation trauma.
