[Paclitaxel plus Bevacizumab Combination Therapy for Esophageal Metastasis of Breast Cancer-A Case Report].

An 80-year-old woman with a history of left breast cancer complained of dysphagia. At the age of 67 years, she had undergone a left modified radical mastectomy, chemotherapy, and endocrine therapy for left breast cancer. Six years after adjuvant therapy completion, she developed dysphagia. Chest CT showed only midesophageal stenosis. Endoscopic examination revealed whole circumferential stenosis without mucosal abnormality located 25 cm from the incisors, and a biopsy showed histologically normal mucosa. Endoscopic balloon dilatation was performed 5 times in 1 year and 3 months. Subsequently, a biopsy specimen revealed adenocarcinoma, which suggested metastasis from the previous breast cancer. One month after the initiation of tamoxifen administration, dyspnea due to pleural effusion was encountered. We treated this via pleural adhesion therapy and changed the treatment to paclitaxel plus bevacizumab combination therapy. She continued paclitaxel plus bevacizumab therapy for 1 year and 4 months without any signs of recurrence.

Efficacy of thoracotomy and thoracoscopic-assisted esophageal surgery in conversion and salvage surgeries: a retrospective study.

BACKGROUND: The esophagus has no serosa; therefore, esophageal cancer may quickly invade its adjacent organs. In recent years, reports of conversion surgery (CS) and salvage surgery (SS) have described resection of esophageal cancer previously considered unresectable, with the addition of intensive preoperative chemotherapy or chemoradiotherapy. Currently, there is no established method for determining whether tumor excision is possible. Additionally, differences in surgical approaches between facilities may influence outcome after resection. However, the option for resection is considered a significant factor in determining a patient's prognosis. METHODS: Patients who were diagnosed with advanced-stage (T3 or higher) squamous cell carcinoma of the esophagus and subsequently underwent resection with CS or SS were included in the study. Resection was performed through a small thoracotomy using a thoracoscope. Clinicopathologic factors, such as complete resection rate (R0) and prognosis, were investigated. RESULTS: A total of 49 surgeries were conducted: 39 CS and 10 SS cases. The male-to-female ratio was 37:12. R0:R1:R2 equals 42:3:4, and the R0 resection rate was 85.7%. The 5-year survival rates for CS and SS cases were 69.2% and 32.1%, respectively. The 5-year survival rates for R0, R1, and R2 resections were 63.4%, 0.0%, and 25.0%, and those for R0 and R1 + 2 resections were 63.4% and 14.3%, respectively, indicating that the prognosis for R0 resection cases was significantly better (P = 0.001 and P = 0.001, respectively). Regarding chemotherapy for CS, 29 patients received 5-FU and cisplatin therapy, whereas 10 patients received 5-FU, cisplatin, and docetaxel (DCF) therapy. After 2015, the ratio of DCF was significantly high, and the R0 resection rate was 100% in patients who received DCF therapy. CONCLUSIONS: In this study, a satisfactory R0 rate was achieved using the magnifying effect of the thoracoscope while ensuring safety during thoracotomy. TRIAL REGISTRATION: This was a single-center cohort study wherein clinical data were retrospectively registered. This study was approved by the Chiba Cancer Center review board (H29-262). All procedures adhered to the ethical standards of the responsible committee on human experimentation and the Helsinki Declaration of 1964 and its later amendments.

Circulating anti-human leukocyte antigen IgM antibodies as a potential early predictor of allograft rejection and a negative clinical outcome after lung transplantation.

PURPOSE: Anti-human leukocyte antigen (HLA) immunoglobulin (Ig) M production stimulated by an alloantigen is sensitive, making IgM a novel potential marker of allorejection after organ transplantation. This study examined the relationship between the serum levels of anti-HLA IgM early after clinical lung transplantation (LTx) and the post-transplant outcomes. METHODS: Thirty-one consecutive patients who underwent deceased LTx were included. Immunoreactivity against HLA was retrospectively analyzed by measuring the anti-HLA IgM levels in the serum sampled for the first 14 days after LTx. The flow panel reactive antibody technique was used. The ratio of the anti-class I IgM level at each day to baseline was obtained, and the peak IgM level was determined for each case. The correlation between the peak IgM level and subsequent development of acute rejection (AR), chronic lung allograft dysfunction (CLAD), and survival outcomes were examined. RESULTS: The peak IgM level was a significant risk factor for AR within 90 days in univariate and multivariate analyses. In the long term, the patients with positive IgM (peak level > 1.8) tended to have a poorer CLAD-free and overall survival than those with negative IgM. CONCLUSION: Elevation of anti-HLA IgM levels early after LTx may be correlated with a higher incidence of rejection and negative clinical outcomes.

The neutrophil-to-lymphocyte ratio as a novel independent prognostic factor for multiple metastatic lung tumors from various sarcomas.

PURPOSE: Sarcomas are among the most refractory malignant tumors and often recur as pulmonary metastasis. Although the presence of a high neutrophil-to-lymphocyte ratio (NLR) has been associated with the prognosis of several malignancies, the relationship between the NLR and sarcoma with pulmonary metastasis is unclear. We investigated the impact of the NLR in patients who underwent surgical resection for metastatic lung tumors from various sarcomas. METHODS: The subjects of this retrospective study were 158 patients with metastatic lung tumors from various sarcomas, who underwent initial pulmonary metastasectomy between 2006 and 2015. We examined the clinicopathological variables, including the NLR and the characteristics of surgical procedures. Survival was estimated by the Kaplan-Meier method and prognostic factors were evaluated by multivariate analysis. RESULTS: Multivariate analysis revealed significantly better survival of the group with an NLR < 2.26 immediately before the most recent pulmonary metastasectomy, in addition to such factors as the largest resected lesion being < 22 mm, a disease-free interval of > 2 years, and 3 or more pulmonary metastasectomies. CONCLUSION: The NLR immediately before the most recent pulmonary metastasectomy is a novel independent prognostic factor, which may be helpful when considering repeated pulmonary metastasectomy.

Effectiveness of scheduled intravenous acetaminophen in the postoperative pain management of video-assisted thoracic surgery.

PURPOSE: The scheduled administration of intravenous acetaminophen (scheduled-IV-AcA) is one of the more effective multimodal analgesic approaches for postoperative pain in abdominal/orthopedic surgeries. However, there is little evidence concerning scheduled-IV-AcA after general thoracic surgery, especially when limited to video-assisted thoracoscopic surgery (VATS). We investigated the efficacy of scheduled-IV-AcA administration in patients after undergoing VATS. METHODS: Ninety-nine patients who underwent VATS lobectomy or segmentectomy via an 8-cm access window and 1 camera port were retrospectively reviewed by categorizing them into groups either with scheduled-IV-AcA (Group AcA: n = 29) or without it (Group non-AcA: n = 70). Group AcA received 1 g of IV-AcA every 6 h from the end of the operation until the end of POD2. Postoperative pain was measured using a numeric rating scale (NRS) three times per day until discharge. RESULTS: NRS scores were significantly lower in Group AcA with motion (on POD1 to the first point of POD2) than in Group non-AcA. Group non-AcA was also more likely to use additional analgesics than Group AcA (39% vs. 17%, p = 0.058). CONCLUSIONS: Scheduled-IV-AcA administration is a safe and effective multimodal analgesic approach in patients undergoing VATS pulmonary resection via an 8-cm access window.

Right single lung transplantation using an inverted left donor lung: interposition of pericardial conduit for pulmonary venous anastomosis - a case report.

BACKGROUND: Lung transplantation (LTx) is still limited by the shortage of suitable donor lungs. Developing flexible surgical procedures can help to increase the chances of LTx by unfolding recipient-to-donor matching options based on the pre-existing organ allocation concept. We report a case in which a successful left-to-right inverted LTx was completed using the interposition of a pericardial conduit for pulmonary venous anastomosis. CASE PRESENTATION: A left lung graft was offered to a 59-year-old male who had idiopathic pulmonary fibrosis with predominant damage in the right lung. He had been prescribed bed rest with constant oxygen inhalation through an oxymizer pendant and had been on the waiting list for 20 months. Considering the condition of the patient (LAS 34.3) and the scarcity of domestic organ offers, the patient was highly likely to be incapable of tolerating any additional waiting time for another donor organ if he was unable to accept the presently reported offer of a left lung. Eventually, we decided to transplant the left donor lung into the right thorax of the recipient. Because of the anterior-posterior position gap of the hilar structures, the cuff lengths of the pulmonary veins had to be adjusted. The patient did not develop any anastomotic complications after the transplantation. CONCLUSIONS: A left-to-right inverted LTx is technically feasible using an autologous pericardial conduit for pulmonary venous anastomosis in selected cases. This technique provides the potential benefit of resolving challenging situations in which surgeons must deal with a patient's urgency and the logistical limitations of organ allocation.

A single-nucleotide polymorphism in a gene modulating glucocorticoid sensitivity is associated with the decline in total lung capacity after lung transplantation.

PURPOSE: Glucocorticoids are used to prevent chronic lung allograft dysfunction (CLAD) after lung transplantation (LT). Our study was aimed at assessing the association between the glucocorticoid-induced transcript 1 gene (GLCCI1) variant, which modulates glucocorticoid sensitivity, and the postoperative lung function and development of CLAD after LT. METHODS: A total of 71 recipients of LT were genotyped for the GLCCI1 variant (rs37972) and divided into three groups: the homozygous mutant allele (TT) group, the heterozygous mutant allele (CT) group, and the wild-type allele (CC) group. The results of pulmonary function tests were compared with the postoperative baseline values. RESULTS: The total lung capacity (TLC) in the TT group was significantly lower than that in the CC group at 3 years after LT (P = 0.029). In the recipients of cadaveric LT, the TLC and forced expiratory volume in 1 s in the TT group were significantly lower than those in the CC groups, resulting in a significant worse CLAD-free survival at 3 years after LT (P = 0.016). CONCLUSION: The GLCCI1 variant was associated with a significant decrease of the TLC at 3 years after LT and the development of CLAD at 3 years, especially in patients undergoing cadaveric LT.

Feasibility of lung transplantation from donors mechanically ventilated for prolonged periods.

PURPOSE: When patients are mechanically ventilated for more than 5 days, they are usually declined as donors for lung transplantation (LTx); thus, the long-term outcomes of LTx from such donors remain unclear. We investigated the feasibility of LTx from donors that had been mechanically ventilated for prolonged periods. METHODS: The subjects of this retrospective comparative investigation were 31 recipients of LTx from donors who had been mechanically ventilated for < 5 days (short-term group) and 50 recipients of LTx from donors who had been mechanically ventilated for ≥ 5 days (long-term group). RESULTS: The median duration of donor mechanical ventilation was 3 days in the short-term group and 8.5 days in the long-term group. However, other than the difference in the duration of donor ventilation, there were no significant differences in the clinical characteristics of the donors or recipients between the groups. The overall survival rate after LTx was comparable between the long-term group and short-term group (5-year survival rate, 66.6% vs. 75.2%). CONCLUSION: The potential inclusion of donors who have been on mechanical ventilation for more than 5 days could be a feasible strategy to alleviate donor organ shortage.

Impact of chronic lung allograft dysfunction, especially restrictive allograft syndrome, on the survival after living-donor lobar lung transplantation compared with cadaveric lung transplantation in adults: a single-center experience.

PURPOSE: The differences in chronic lung allograft dysfunction (CLAD) between living-donor lobar lung transplantation (LDLLT) and cadaveric lung transplantation (CLT) remain unclear. We conducted this study to compare the impact of CLAD on the outcomes after LDLLT vs. CLT. METHODS: We conducted a retrospective review of the data of 97 recipients of bilateral lung transplantation, including 51 recipients of LDLLT and 46 recipients of CLT. RESULTS: The CLAD-free survival and overall survival after LDLLT were similar to those after CLT. CLAD and restrictive allograft syndrome (RAS), but not bronchiolitis obliterans syndrome (BOS), developed significantly later after LDLLT than after CLT (p = 0.015 and p = 0.035). Consequently, patients with CLAD and RAS, but not those with BOS, after LDLLT had a significantly better overall survival than those after CLT (p = 0.037 and p = 0.0006). Furthermore, after the diagnosis of CLAD, the survival of patients with RAS after LDLLT tended to be better than that after CLT (p = 0.083). CONCLUSION: CLAD, especially RAS, appears to develop later after LDLLT than after CLT and seems to have a lower impact on the overall survival after LDLLT than that after CLT.

SOCS3 overexpression in T cells ameliorates chronic airway obstruction in a murine heterotopic tracheal transplantation model.

PURPOSE: Suppressor of cytokine signaling-3 (SOCS3) is a negative feedback inhibitor of cytokine signaling with T-cell-mediated immunosuppressive effects on obliterative bronchiolitis (OB). In this study, we aimed to investigate the impact of T-cell-specific overexpression of SOCS3 using a murine heterotopic tracheal transplantation (HTT) model. METHODS: Tracheal allografts from BALB/c mice were subcutaneously transplanted into wild-type C57BL/6J (B6; WT) mice and SOCS3 transgenic B6 (SOCS3TG) mice. Tracheal allografts were analyzed by immunohistochemistry and quantitative polymerase chain reaction assays at days 7 and 21. RESULTS: At day 21, allografts in SOCS3TG mice showed significant amelioration of airway obstruction and epithelial loss compared with allografts in WT mice. The intragraft expression of IFN-γ and CXCL10 was suppressed, while that of IL-4 was enhanced in SOCS3TG mice at day 7. The T-bet levels were lower in SOCS3TG allografts than in WT allografts at day 7. CONCLUSION: We revealed that the overexpression of SOCS3 in T cells effectively ameliorates OB development in a murine HTT model by inhibiting the Th1 phenotype in the early phase. Our results suggest that the regulation of the T-cell response, through the modulation of SOCS expression, has potential as a new therapeutic strategy for chronic lung allograft dysfunction.

Low-risk donor lungs optimize the post-lung transplant outcome for high lung allocation score patients.

PURPOSE: The lung allocation score (LAS) has been generally recognized as a contributor to the overall survival in lung transplant candidates. However, donor-related risks have never been taken into consideration in previous research that validated the LAS. This study aimed to determine whether or not the role of the LAS as a predictor of the posttransplant outcome is influenced by the quality of the donor lungs. METHODS: We retrospectively reviewed 108 patients who underwent lung transplantation at Okayama University Hospital since 1998. The cohort was divided into two groups based on the lung donor score (DS; ≤ 4/> 4). Correlations between the LAS and posttransplant outcomes were investigated in both groups. RESULTS: In the high-DS group, an elevated LAS was strongly associated with posttransplant PaO2/FiO2 (p = 0.018). However, in the low-DS group, no correlation was found between them. There was no significant difference in the long-term survival according to the LAS in the low-DS group. The LAS effectively predicted the posttransplant outcome only when lungs with DS > 4 were transplanted; the LAS was not reliable if high-quality lungs were transplanted. CONCLUSION: Lung transplantation can be feasible and provides a survival benefit even for high-LAS patients if lungs from a low-risk donor are transplanted.

Airway complications have a greater impact on the outcomes of living-donor lobar lung transplantation recipients than cadaveric lung transplantation recipients.

PURPOSE: Airway complications (ACs) after living-donor lobar lung transplantation (LDLLT) could have different features from those after cadaveric lung transplantation (CLT). We conducted this study to compare the characteristics of ACs after LDLLT vs. those after CLT and investigate their impact on outcomes. METHODS: We reviewed, retrospectively, data on 163 recipients of lung transplantation, including 83 recipients of LDLLT and 80 recipients of CLT. RESULTS: The incidence of ACs did not differ between LDLLT and CLT. The initial type of AC after LDLLT was limited to stenosis in all eight patients, whereas that after CLT consisted of stenosis in three patients and necrosis in ten patients (p = 0.0034). ACs after LDLLT necessitated significantly earlier initiation of treatment than those after CLT (p = 0.032). The overall survival rate of LDLLT recipients with an AC was significantly lower than that of those without an AC (p = 0.030), whereas the overall survival rate was comparable between CLT recipients with and those without ACs (p = 0.25). CONCLUSION: ACs after LDLLT, limited to bronchial stenosis, require significantly earlier treatment and have a greater adverse impact on survival than ACs after CLT.

Pulmonary artery patch for an inadequate donor atrial cuff in the absence of donor pericardium in lung transplantation.

In cadaveric lung transplantation (LTx), a donor lung with an inadequate donor left atrial cuff is considered a "surgically marginal donor lung". The donor pericardium is commonly applied to reconstruct the inadequate donor left atrial cuff; however, in some cases, the donor pericardium is inadvertently removed during the lung procurement. We devised an alternative technique for reconstruction to overcome the absence of pericardium in a donor lung with an inadequate atrial cuff, using a patch of the donor pulmonary artery (PA) in single lung transplantation. In a recent case of lung transplantation in which the donor pericardium had been removed, we harvested a segment of the right PA distal to the main PA of the donor and used a PA patch to repair the inadequate donor left atrial cuff. No vascular complications were encountered in the recipient, who remains in good health after the transplantation.

Balloon-expandable Metallic Stents for Airway Diseases.

Stent placement is an essential treatment for airway diseases. Although self-expandable metallic stents and silicone stents are commonly applied for the treatment of airway diseases, these stents are unsuitable for the treatment of small airway diseases encountered in pediatric patients and lung transplant recipients with airway complications. Currently, only vascular balloon-expandable metallic stents are available for the treatment of small airway diseases; however, little research has been conducted on the use of these stents in this field. We have launched a prospective feasibility study to clarify the safety and efficacy of balloon-expandable metallic stents for the treatment of airway diseases.

[Two cases of dural metastasis of breast cancer].

The first case of dural metastasis occurred in a 60s years old woman, who presented with bone metastasis to the right breast. Nine months later, disorientation and left hemiplegia developed, the right coronal bone metastasis enlarged, and dural metastases were detected close to the tumor, as observed by using cranial magnetic resonance imaging (MRI). Whole brain radiation and chemotherapy(weekly paclitaxel)were administered. The right coronal bone metastasis reduced remarkably, and the dural metastases almost disappeared, as observed on a cranial MRI scan. The second case of dural metastasis occurred in a 50s years old woman who presented with multiple bone metastases. Extensive bone metastases to the skull and dural metastases to the side of the head were observed on cranial MRI scans. Subsequently, the patient experienced a severe headache, and whole brain radiation and pharmacotherapy with anastrozole and trastuzumab were administered. Cranial MRI revealed that the skull bone metastasis reduced and the dural metastases almost disappeared. We report that radiotherapy and pharmacotherapy were effective in these 2 cases of dural metastases of breast cancer.

In vivo lung perfusion for prompt recovery from primary graft dysfunction after lung transplantation.

BACKGROUND: No proven treatment after the development of primary graft dysfunction (PGD) is currently available. Here, we established a novel strategy of in vivo lung perfusion (IVLP) for the treatment of PGD. IVLP involves the application of an in vivo isolated perfusion circuit to an implanted lung. This study aimed to explore the effectiveness of IVLP vs conventional post-lung transplant (LTx) extracorporeal membrane oxygenation (ECMO) treatment using an experimental swine LTx PGD model. METHODS: After 1.5-hour warm ischemia of the donor lungs, a left LTx was performed. Following the confirmation of PGD development, pigs were divided into 3 groups (n = 5 each): control (no intervention), ECMO, and IVLP. After 2 hours of treatment, a 4-hour functional assessment was conducted, and samples were obtained. RESULTS: Significantly better oxygenation was achieved in the IVLP group (p ≤ 0.001). Recovery was confirmed immediately and maintained during the following 4-hour observation. The IVLP group also demonstrated better lung compliance than the control group (p = 0.045). A histologic evaluation showed that the lung injury score and terminal deoxynucleotidyl transferase dUTP nick end labeling assay showed significantly fewer injuries and a better result in the wet-to-dry weight ratio in the IVLP group. CONCLUSIONS: A 2-hour IVLP is technically feasible and allows for prompt recovery from PGD after LTx. The posttransplant short-duration IVLP strategy can complement or overcome the limitations of the current practice for donor assessment and PGD management.

Large esophageal gastrointestinal stromal tumors resected thoracoscopically after oral imatinib therapy: a report of two cases.

Esophageal gastrointestinal stromal tumors (GISTs) are very rare, accounting for 2-5% of all GISTs. As with other GISTs, the principle of surgical treatment is complete resection with negative margins. In addition to biological grades of GISTs itselves, local recurrence due to capsular damage is a known risk. We describe two cases of massive esophageal GISTs that were successfully resected thoracoscopically after 2 months administration of 400 mg imatinib, with some discussion of the literature. Case 1, the patient was a 51-years-old man. After treated with 400 mg of imatinib as preoperative chemotherapy for 2 months, we performed surgery that included right thoracoscopic subtotal esophagectomy, gastric tube reconstruction, and jejunostomy. The resection specimen and histopathology were esophageal GIST-LtMtAeG, 110 × 95 mm. The postoperative course was uneventful, and was discharged on postoperative day 14. The patient has been recurrence free for 11 months postoperatively. Case 2, the patient was a 70-years-old man. After treated with 400 mg of imatinib as preoperative chemotherapy for 2 months, we performed surgery that included right thoracoscopic subtotal esophagectomy, gastric tube reconstruction, and jejunostomy. The resection specimen and histopathology were esophageal GIST-LtAeG, 90 × 52 mm. The postoperative course was uneventful, and was discharged on postoperative day 14. The patient has been recurrence free for 9 months postoperatively.

[Primary mediastinal lymphoma; a clinicopathologic case series].

Treatment for primary mediastinal lymphoma generally involves chemotherapy and radiotherapy, and treatment regimens depend on histologic subtypes of lymphoma. The histologic subtype of lymphoma is mostly determined by computed tomography (CT)-guided core-needle biopsy or surgical procedures, including thoracotomy, thoracoscopy and mediastinoscopy. We describe the clinicopathologic features and diagnostic procedures of 8 cases of primary mediastinal lymphoma. The male-to-female ratio was 1:1, and median age at diagnosis was 27 years. The median size of the primary mediastinal tumor on CT was 8.5 cm. Five patients were diagnosed by CT-guided core-needle biopsy, 1 by open biopsy and 2 by surgery. Three patients were diagnosed with nodular sclerosis Hodgkin lymphoma, 3 with mediastinal diffuse large B-cell lymphoma, 1 with precursor T-lymphoblastic leukemia/lymphoma and 1 with thymic extranodal marginal zone B-cell lymphoma. According to their histological subtypes, 5 patients were treated with chemoradiotherapy, 2 patients with chemotherapy and 1 patient of thymic extranodal marginal zone B-cell lymphoma with surgery alone. All patients survived in the median follow-up of 34.5 months. Appropriate biopsy procedure should be performed in patients with suspected mediastinal lymphoma.

[A case of gastric cancer with rhabdoid features showing better prognosis through S-1/CDDP chemotherapy].

Although gastric cancers(GCs)with rhabdoid features are rare, they are known to show a poorer prognosis compared with conventional GCs. Indeed, more than half of reported GCs with rhabdoid features died within 6 months after receiving any kind of initial treatment. Obviously, no effective chemotherapy has been reported. In this study, we present a case of GC with rhabdoid features which showed a better response to a chemotherapy, S-1/CDDP, and lived for over 12 months after the initial chemotherapy. A 75-year-old man was seen in our hospital for epigastralgia. Detailed examinations revealed that he had GC at Stage IV. Consequently, he underwent S-1/CDDP treatment. This treatment produced a good response for 6 months, minimizing the size of the primary tumor and eradicating distant metastases. Re-growth of the primary tumor without uprising distant metastasis was confirmed 8 months after the initialS -1/CDDP treatment, and the patient went through a gastrectomy for curative care. After surgery, a precise pathological examination revealed that the primary tumor possessed a poorly differentiated adenocarcinoma that contained tumor cells with typical rhabdoid features. In the end, the patient died of liver metastasis 13 months after the initial S-1/CDDP chemotherapy.

A right pulmonary vein abnormality treated with 3D CT assistance in thoracoscopic surgery for esophageal cancer: a case report.

BACKGROUND: Anomalous bifurcation of the right superior pulmonary vein is an important anomaly that should be recognized not only in respiratory and cardiac surgeries, but also in esophageal surgery for the safe performance of surgery. We report a case in which thoracoscopic esophagectomy was safely performed using preoperative three-dimensional computed tomography (3D CT) imaging. CASE PRESENTATION: An 81-year-old male patient received an upper gastrointestinal endoscopy, which revealed a 20-cm incisor at the entrance, 43-cm EGJ, and 30-mm large type 1 + IIc lesion between the 23-cm and 26-cm incisors; biopsy showed squamous cell carcinoma (SCC). Contrast-enhanced CT showed wall thickening in the anterior wall of the upper thoracic esophagus, without evidence of multi-organ invasion or lymph node metastasis. In addition, a break in the right pulmonary vein passing dorsal to the right main bronchus and flowing directly into the left atrium was observed, and 3D CT was performed preoperatively to confirm the 3D positioning. Positron emission tomography (PET)-CT showed a high degree of accumulation (SUVmax 19.95) in the upper thoracic esophagus. The patient was diagnosed with upper thoracic esophageal cancer, cT2N0M0 cStage II, and underwent thoracoscopic subtotal esophagectomy (three-region dissection) and gastric tube reconstruction. The dorsal inflow of the pulmonary vein in the right main bronchus, which was recognized on preoperative CT, was confirmed and preserved. The pathological diagnosis was basaloid squamous cell carcinoma, pT1b(SM1)N0(0/58)M0 pStage I. The postoperative course was uneventful, and the patient was discharged on postoperative day 20. CONCLUSIONS: The anomalous bifurcation of the pulmonary vein in the right upper lobe area required attention because of its potential to cause massive bleeding and difficulty in securing the operative field if misidentified and damaged during surgery. Although it is not frequently encountered, it is the bifurcation anomaly that esophageal surgeons must bear in mind due to its severe consequences. Preoperative image-reading and intraoperative manipulation of this vessel are imperative for surgical safety.
