Purpose
Primary spinal osteosarcoma is quite rare, and the 5-year survival rate is very low. Because of its rarity, successful treatment experience with spinal osteosarcoma is limited. The purpose of this study is to report the effect of therapy of primary osteosarcoma of spine by carbon-ion radiotherapy (CIRT) and long-term follow.Methods
A 70-year-old with primary spinal osteosarcoma who received CIRT underwent combined anterior artificial vertebral body replacement and posterior lumbar fusion (L1–L5) 3 years later.Results
According to the surgical resection of tumoral lesion, pathological results showed that the intertrabecular space previously filled with tumor cells on the initial biopsy sample now contained necrotic tissue without tumor cells. This means that primary osteosarcoma of the spine was completely eliminated and achieved local control with CIRT, with a 7-year follow-up after the initial treatment.Conclusions
Carbon ion beam treatment is an effective local treatment for patients with spinal osteosarcoma for whom surgical resection is not a feasible option, especially for elderly patients. However, more patients need to be evaluated over a longer term to assess the curative effect of CIRT.2.

Purpose
Transurethral resection of bladder tumor (TURBT) using a wire loop is considered the gold standard for staging and treating non-muscle invasive bladder cancer (NMIBC). TURBT is associated with serious disadvantages that facilitate tumor recurrence. The present study evaluated the safety and efficacy of the bipolar button electrode for en bloc resection of NMIBC.Methods
From January 2013 to July 2016, 82 consecutive patients newly diagnosed with NMIBC received transurethral en bloc resection with bipolar button electrode. Operative details, pathological result, and intraoperative and postoperative complications regarded as safety outcomes were documented. Each patient was followed up for ≥ 18 months.Results
A total of 118 neoplasms were removed en bloc from 82 patients. The mean tumor diameter was 2.42 ± 1.34 cm. The average operation time was 35 ± 14 min. No complications such as bladder bleeding, vesicle perforation, and obturator nerve reflex occurred during the treatment. Pathological evaluations showed urothelial carcinoma with stage Ta low grade in 26 patients, T1 high grade in 51 patients, and T2 high grade in 5 patients. In addition, the bladder detrusor muscle layer was provided in all cases. The 18-month recurrence-free survival was 88.5% (23/26) and 74.5% (38/51) for Ta and T1 patients, respectively.Conclusions
The current results demonstrated that transurethral en bloc resection with bipolar button electrode is an effective, feasible, and safe treatment for NMIBC.3.
Purpose
To evaluate the efficacy of single-stage posterior vertebral column resection for old thoracolumbar fracture–dislocations with spinal cord injury.Methods
From January 2007 to June 2013, twelve male patients (average age, 32.6 years; range 19–57 years) with old fracture–dislocations of the thoracolumbar spine and spinal cord injury underwent single-stage posterior vertebral column resection and internal fixation. All patients were assessed for relief of the pain and restoration of neurologic function. Postoperative Cobb angle was measured and bone graft fusion was evaluated by X-ray. A systematic review of 25 studies evaluating surgical management of thoracolumbar fractures with spinal cord injuries was also performed.Results
From our case series, six of the nine patients with Frankel grade A had significant improvement in urination and defecation after surgery. The three patients with Frankel grades B and C had progression of 1–2 grades after surgery. Bony fusion was achieved and local back pain was relieved in all patients after surgery. From our systematic review of 25 studies, the majority of patients had improved back pain, the postoperative kyphotic angle was significantly reduced compared with pre-operative kyphotic angle.Conclusion
Single-stage posterior vertebral column resection and internal fixation for old thoracolumbar fracture–dislocations is an ideal treatment allowing for thorough decompression, relief of pain, correction of deformities, and restoration of spinal stability.Level of evidence

Purpose
We aimed to identify the risk factors for thoracic and spinal deformities following lung resection during childhood and to elucidate whether thoracoscopic surgery reduces the risk of complications after lung resection.Methods
We retrospectively examined the medical records of all pediatric patients who underwent lung resection for congenital lung disease at our institution between 1989 and 2014.Results
Seventy-four patients underwent lung resection during the study period and were followed-up. The median age of the patients at the time of surgery was 5 months (range 1 day–13 years), and 22 were neonates. Thoracotomy and thoracoscopy were performed in 25 and 49 patients, respectively. Thoracic or spinal deformities occurred in 28 of the 74 patients (37%). Univariate analyses identified thoracotomy, being a neonate (age: <1 month) at the time of surgery, and being symptomatic at the time of surgery as risk factors for these deformities. However, a multivariate analysis indicated that only thoracotomy and being a neonate were risk factors for deformities.Conclusions
Thoracoscopic surgery reduced the risk of thoracic and spinal deformities following lung resection in children. We suggest that, where possible, lung resection should be avoided until 2 or 3 months of age.5.

Study design
Eighteen consecutive patients with adult-onset intradural spinal teratoma underwent surgical treatment in our center from 1998 to 2013.Background and purpose
Teratoma is defined as a neoplasm composed of elements derived from three germ cell layers (ectoderm, endoderm and mesoderm). Intraspinal teratoma is extremely rare and accounts for 0.2–0.5% of all spinal cord tumors. Moreover, teratoma occurs primarily in neonates and young children. Adult-onset intradural spinal teratoma is even rare. The aim of this study was to discuss the clinical characteristics, diagnosis and therapeutic strategies of adult-onset intradural spinal teratoma.Methods
This retrospective study included 18 consecutive adult patients with intradural teratoma who were surgically treated in our center between 1998 and 2013. The clinical features, pathogenesis, diagnostic strategies and surgical outcomes were discussed. Neurological function outcomes were evaluated by the JOA scoring system.Results
Of the 18 included patients, 4 patients received subtotal resection and the other 14 patients received total resection. All the 18 cases were diagnosed with mature teratoma. The mean follow-up period was 79.7 (median 60.5; range 27–208) months. Local recurrence occurred in two of the four patients who underwent subtotal resection and in no patient who underwent total resection. The neurologic status improved in 16 cases and remained unchanged in the other two patients.Conclusions
Adult-onset intradural spinal teratoma is extremely rare. To the best of our knowledge, this is the largest series of patients with this disease. Despite the slow-growth and indolent nature, radical resection remains the recommended treatment to reduce tumor recurrence.7.
Purpose
To evaluate the risk factors for peritoneal recurrence (PR) of pancreatic adenocarcinoma and to discuss the appropriate management strategies.Methods
We reviewed the medical records of 236 patients who underwent pancreatectomy for pancreatic adenocarcinoma. We then compared the clinicopathological characteristics of patients with vs. those without PR. The independent risk factors for PR were defined using the Cox proportional hazards regression model.Results
The median survival of patients with PR was 13.3 months after surgical treatment. The PR group had a significantly higher incidence of portal vein resection, longer operative time (≥648 min), greater blood loss (≥2179 mL), blood transfusion, tumor size, portal vein invasion, artery invasion, pancreatic nerve plexus invasion, and histological grade. Multivariate analysis revealed that excessive blood loss (≥2179 mL; P = 0.010), artery invasion (P = 0.025), pancreatic nerve plexus invasion (P = 0.001), and histological grade 3 (P = 0.011) were independent risk factors for PR. Excessive blood loss was also strongly related to tumor size (P = 0.018).Conclusions
Local invasion and tumor size-related factors suggested the possibility of intraoperative dissemination at the time of tumor resection. Preoperative treatment and an operative procedure to prevent tumor exposure may help prevent PR.8.

Background
Resection of musculoskeletal soft tissue tumors can cause large resection defects.Objective
Which defects after resection of musculoskeletal soft tissue tumors can be covered?Methods
A literature search was carried out, the results were analyzed and are discussed.Results
Musculoskeletal soft tissue tumors are comparatively rare tumors in Germany. There are guidelines for oncological therapy. Even though there are no guidelines for the plastic reconstruction after musculoskeletal soft tissue tumor resection, multiple concepts have been described in the literature. A differentiation must be made between the resection defect coverage and the restoration of function. The donor site morbidity must also be taken into account when planning the covering. In addition to reconstructions with autologous tissue, a reconstruction with prostheses is also possible.Conclusion
Decisive for the successful therapy is the early involvement of the plastic or reconstructive surgeon in the treatment planning in order to achieve an optimal result for the patient.9.
Background
Surgical site infection is a catastrophic complication after spinal surgery, which seriously affects the progress of rehabilitation and clinical outcome. Currently the clinical reports on spinal surgical site infections are mostly confined to the surgical segment itself and there are few reports on adjacent segment infections after spinal surgery.Study design
Case report.Objective
To report a clinical case with adjacent level infection after spinal fusion.Methods
We report the case of a 68-year-old woman who underwent posterior lumbar 4?5 laminectomy, posterolateral fusion and internal fixation. The patient showed signs of surgical site infection, such as surgical site pain, high fever and increase of the inflammatory index 1 week after the operation. Magnetic resonance imaging (MRI) confirmed the diagnosis of adjacent intervertebral disc infection. The patient received early combined, high-dose anti-infection treatment instead of debridement.Results
After the conservative treatment, the infection was controlled and the patient subsequently enjoyed a normal daily life.Conclusion
Adjacent level infections can occur after spinal surgery. Early diagnosis and anti-infection treatment played an important role in the treatment of this kind of complication.10.

Purpose
We devised a simple dichotomous classification system and showed sufficient reproducibility to indicate treatment strategies for peritoneal metastasis of colorectal cancer.Methods
We included 67 patients with peritoneal metastasis of colorectal cancer and classified them according to the largest lesion size, number of lesions and number of regional peritoneal metastases. The oncological data were recorded and compared.Results
According to the univariate analyses, the prognoses were significantly better in patients with ≤3 disseminated lesions than in those with ≥4, and in patients with disseminated lesions in only one region than in those with ≥2 lesions. A multivariate analysis showed that primary tumor resection and the presence of peritoneal metastases in only one region were favorable factors for the patient survival. Patients with disseminated lesions in only one region (localized group) and those with nonlocalized lesions had three-year survival rates of 45.6 and 12.2 %, respectively. Finally, primary tumor resection improved the prognoses in both the localized and nonlocalized groups.Conclusions
Colorectal cancer patients were categorized into localized and nonlocalized groups according to the number of regions with peritoneal metastasis, and significant prognostic associations were demonstrated. Subsequent analyses of the oncological data suggested that primary tumor resection contributes to an improved prognosis in all patients with synchronous peritoneal metastases.11.
Background
Sublobar resection of lung cancer may benefit patients with lung cancer presenting as ground-glass opacity (GGO) nodules. The purpose of this study was to evaluate the effect of margin width on recurrence after sublobar resection in patients with clinical N0 non-small cell lung cancer presenting as GGO-predominant nodule.Methods
We conducted a retrospective chart review of 91 patients treated for clinical N0 non-small cell lung cancer ≤3 cm by sublobar resection with clear resection margins. We assigned them to two groups: GGO-predominant tumor and solid-predominant tumor. Each group was subdivided into two groups according to the margin width: resection margin ≤5 mm and resection margin >5 mm. We analyzed the clinicopathological findings and survival among these four groups.Results
There was no recurrence in GGO-predominant tumors after sublobar resection. Margin width did not influence the recurrence in GGO-predominant tumors. In the cases of solid-predominant tumor, 5-year recurrence-free survival after sublobar resection according to margin width ≤5 and >5 mm was 24.2 and 79.6 %, respectively (p < 0.001). Therefore, narrow margin width (resection margin ≤5 mm) was a significant risk factor for recurrence of solid-predominant tumors (hazard ratio 3.868, 95 % confidence interval 1.177–12.714, p = 0.026).Conclusions
The width between the tumor and resection margin does not affect the recurrence after R0 sublobar resection in patients with clinical N0 GGO-predominant lung cancer ≤3 cm. By contrast, margin width is a significant risk factor for recurrence after sublobar resection in patients with clinical N0 solid-predominant lung cancer.12.
Objective
Coracoacromial ligament release to widen the subacromial space, resection of the anterior undersurface of the acromion and, if needed, caudal exophytes at the acromioclavicular joint.Indications
All types of outlet impingement after 3 months of conservative treatment.Contraindications
Impingement syndrome with instability/muscular imbalance, massive rotator cuff tear, unstable os acromionale, posterior–superior impingement, joint infection, freezing phase of a secondary frozen shoulder.Surgical technique
Lateral decubitus position with traction device for the arm. Diagnostic arthroscopy of the glenohumeral joint via standard portals. With arthroscope moved to the subacromial space, bursectomy, electrosurgical release of coracoacromial ligament, resection of acromial hook through standard posterior portal.Postoperative management
Physiotherapy or self-exercises on postoperative day 1, pain-adapted analgesia to avoid shoulder stiffness.Results
Several studies present positive long-term results compared to conservative treatment (and open acromioplasty) for partial rotator cuff tears and for elderly patients. With a 20-year follow-up, successful results have been achieved for all patients with isolated impingement syndrome.13.

Objective
Debridement of infected tissue with the main aim being the re-establishment of mobilization with preservation of standing and walking ability. Prevention of secondary pressure points or amputations due to inadequate resection or deficient soft tissue cover.Indications
In the case of increasing necrosis of the big toe, surgical abrasion and/or amputation is considered unavoidable. Other indications where surgery could be considered include diabetes and its associated angiopathies together with peripheral arterial angiopathy.Contraindications
In the case of insufficient blood supply an expansion of the resection margins should be taken into account. If there are possible alternatives to amputation. Surgery for patients with renal failure requiring dialysis associated with increased complication rate.Surgical technique
A dorsal cuneiform resection is performed to facilitate implantation of a plantar skin transplant and wound healing. Important is the resection of bone in a slide oblique technique. Amputation scars should be outside pressure zones. Partial amputations in the area of the first ray as exarticulation or via the individual amputated segments possible (as opposed to toes 2–5).Postoperative management
Direct postoperative weight-bearing with rigid insole and dispensing aid for 6–8 weeks. Following complete wound healing, foot support with orthopedic arch and transverse strain relief should be advocated, together with a joint roll in ready-made individual shoes.Results
Both trauma and nontrauma cases were included in our present cohort. A total of 7 cases were surgically revised in 2014 due to superficial skin necrosis that was likely the result of skin tension from the wound stitches.14.
Purpose
Total en bloc spondylectomy (TES) is a surgical procedure performed to achieve complete resection of an aggressive benign spinal tumor or a malignant spinal tumor. When reconstructing the spine after resection, we have been using liquid nitrogen-frozen resected spine bearing tumor as a bone graft, expecting an immunological response to tumor-specific antigen(s). The purpose of this article is to report a successful treatment case of lung adenocarcinoma metastasis with TES and this cryotherapy.Methods
A 59-year-old male presented with rapid progression of neurological deterioration of the lower limbs due to a spinal metastasis from T8 to T10. The primary lung adenocarcinoma had already been excised under thoracoscopy. The patient underwent TES with reconstruction using frozen tumor-bearing vertebra for the bone graft.Results
One month after surgery, a new nodule appeared at the right middle lobe of the lung. However, we carried out no biopsy of the newly emerged nodule and the patient received no adjuvant chemotherapy or radiotherapy. Six months after surgery, the tumor vanished. No local recurrence or metastasis of the tumor has been observed until now.Conclusions
TES with a liquid nitrogen-frozen tumor specimen could be a promising therapeutic option for cancer patients with spine metastasis.15.
Background
Retroperitoneal paragangliomas (PGs) are a rare subgroup of neuroendocrine tumors that are commonly located alongside the abdominal aorta. Complete tumor resection is thought to be restricted in patients with major blood vessel involvement. However, no study has specifically focused on aggressive surgical treatment in such patients. We evaluated the value of en bloc resection with major blood vessel reconstruction for locally invasive retroperitoneal PGs.Methods
Twenty-nine patients with retroperitoneal PGs with major blood vessel involvement were included in this retrospective study. Survival was compared between patients who underwent en bloc resection with major blood vessel reconstruction and those who underwent medical treatment. Prognostic predictors were analyzed in patients who underwent en bloc resection with major blood vessel reconstruction.Results
All 11 patients who underwent medical treatment obtained a pathological diagnosis by computed tomography-guided percutaneous needle biopsy. All 18 patients who underwent en bloc resection with major blood vessel reconstruction achieved complete tumor resection. Overall survival was higher in patients who underwent complete tumor resection than in those who underwent medical treatment (p < 0.05). No perioperative mortality occurred in patients who underwent complete tumor resection. Patients with no metastasis, no organ invasion, R0 resection, a Ki-67 index of ≤3%, and a tumor diameter of ≤11.7 cm showed better tumor-free survival (p < 0.05).Conclusions
En bloc resection with major blood vessel reconstruction can be successfully performed and provide satisfactory outcomes for patients with locally invasive retroperitoneal PGs. This technique may become a standard surgical strategy for properly selected patients.16.

Purpose
Several video-assisted and robotic surgery techniques have been reported for resection of the thyroid and parathyroid glands. Our institute has started performing endoscopic thyroidectomy using the Lap-protector and E·Z-access system, referred to as E·Z-access using video-assisted neck surgery (EZ-VANS). In this report, we evaluate the safety and efficacy of this technique.Methods
From January 2007 to September 2014, 110 patients underwent resection of a primary thyroid tumor, 73 who underwent a cervical collar incision (the Open group) and 37 underwent EZ-VANS (the EZ-VANS group).Results
The average operating time was 159 and 172 min in the Open group and EZ-VANS group, respectively; the amount of blood loss was 46.5 and 54.7 ml, respectively; and the length of hospital stay after surgery was 4.3 and 5.2 days, respectively, with no significant differences observed between the two groups. The learning curve for the EZ-VANS technique was shorter than for open surgery.Conclusions
We confirmed that the EZ-VANS technique is a safe and useful method for resection of benign and early malignant thyroid tumors.17.
Purpose
The tumor-node-metastasis (TNM) classification defines R1 as the presence of tumor cells at the resection margin, while the current Royal College of Pathologists guidelines for pancreaticoduodenectomy specimens regard the presence of tumor cells within 1 mm from the resection margin as R1 (the “1-mm rule”). The aims of this study were to investigate the resection margin status of pancreatic head cancer retrospectively according to both the TNM and 1-mm rule classifications, and to evaluate the postoperative survival and tumor recurrence patterns.Methods
A total of 117 patients with pancreatic head cancer were the subjects of this study.Results
R11-mm rule resection was associated with a significantly worse disease-free survival (DFS) than R01-mm rule resection (p = 0.0259), while R1TNM had no impact on DFS. R11-mm rule resection margin status correlated with the incidence of tumor recurrence in the liver (p = 0.0483). In a multivariate analysis, R11-mm rule resection was the independent variable for predicting poor DFS (hazard ratio 1.71; p = 0.0289).Conclusions
R1 resection margin status determined by the 1-mm rule may be an independent indicator for predicting disease recurrence, especially liver metastasis. These results may be useful for selecting the appropriate adjuvant therapy protocol and conducting strict surveillance in PDAC patients.18.

Introduction
Duodenal neuroendocrine tumors (NETs) are rare neoplasms with poorly defined management. We sought to evaluate the outcomes of patients undergoing resection of duodenal NETs.Methods
Using a multi-institutional database, 146 patients who underwent resection for duodenal NETs between 1993 and 2015 were identified. Data on clinicopathologic characteristics and outcomes were collected and analyzed.Results
Local surgical resection (LR) was performed in 57 (39.0 %) patients, while 50 (34.3 %) patients underwent pancreaticoduodenectomy (PD) and 39 (26.7 %) patients an endoscopic resection (ER). Factors associated with worse RFS included advanced tumor grade and metastasis at diagnosis (both P?<?0.05) but not procedure type (P?>?0.05). Among patients who had at least one lymph node examined (n?=?85), 50 (58.8 %) had a metastatic lymph node; lymph node metastasis (P?=?0.04) and advanced tumor grade (P?=?0.04) were more common among patients with tumors >1.5 cm. Median length-of-stay was longer for PD versus LR (P?<?0.001). PD patients were at increased risk for severe postoperative complications (P?=?0.01).Conclusion
Recurrence of duodenal NETs was dependent on tumor biology rather than procedure type. PD was associated with a longer hospital stay and higher risk of perioperative complications. For patients with tumors ≤1.5 cm, LR or ER may be appropriate with PD reserved for larger lesions and those not amenable to a more local approach.19.

Background/Aims
Some patients experience very late recurrence of HCC more than 5 years after initial therapy. We aimed to clarify the predictive factors for very late recurrence of HCC in such cases.Methods
Among 807 HCC patients undergoing surgical resection or ablative therapy with curative intent, the patients who survived for 5 years without any recurrence were reviewed. The prognosis and possible predictive factors for late recurrence were analyzed retrospectively.Results
A total of 184 patients survived for more than 5 years without recurrence. Among them, 61 patients experienced recurrence, at a median of 6 years after initial therapy. In univariate analysis, the pre-treatment aspartate aminotransferase, alanine aminotransferase, Child-Pugh class, and ALBI grade were not related to recurrence, but those at 5 years after treatment were significantly related to recurrence. By multivariate analysis, an ALBI grade of 2–3 at 5 years was an independent risk factor for recurrence (P?<?0.0001). Moreover, variation of the ALBI grade over the 5 years after the initial treatment was significantly related to recurrence-free survival.Conclusions
The ALBI grade is an effective index of the variation in liver function after curative therapy and may be a useful prognostic factor for the long-term recurrence-free survival of HCC patients.20.
