BACKGROUND: The main predictor of long-term survival in patients with recurrent rectal cancer is surgical resection with a clear resection margin. MRI plays a role in patient selection and surgical planning. OBJECTIVE: This study aimed to validate MRI in determining pelvic involvement by comparing MRI to histological outcomes, to assess the effect of MRI on surgical planning by comparing MRI findings with the surgical procedure, and to compare MRI anatomical involvement with resection outcome to assess if MRI can predict a clear resection margin...

The most commonly accepted indications for cervical disc arthroplasty (CDA) are 1- and 2-level cervical disc herniation or spondylosis causing radiculopathy or myelopathy that is refractory to medical management. Unlike anterior cervical discectomy and fusion (ACDF), which eliminates motion, CDA aims to restore the physiological range of motion of the indexed joint. Thus, the effect of indirect decompression gained by the insertion of a sufficiently large interbody graft and incorporation into arthrodesis after ACDF cannot be duplicated for CDA...

OBJECTIVE With the advent of new adjunctive therapy, the overall survival of patients harboring spinal column tumors has improved. However, there is limited knowledge regarding the optimal bone graft options following resection of spinal column tumors, due to their relative rarity and because fusion outcomes in this cohort are affected by various factors, such as radiation therapy (RT) and chemotherapy. Furthermore, bone graft options are often limited following tumor resection because the use of local bone grafts and bone morphogenetic proteins (BMPs) are usually avoided in light of microscopic infiltration of tumors into local bone and potential carcinogenicity of BMP...

BACKGROUND Epithelioid hemangioendothelioma (EHE) is a rare vascular tumor. We present a single-center study on hepatic EHE cases treated by hepatic resection (HR) or liver transplantation (LT). MATERIAL AND METHODS Six HR patients with hepatic EHE were identified during 5 years from 2010 to 2014; EHE represented 0.13% (6 of 4572) of all primary liver tumors. Two LT recipients were also identified during 12 years from 2003 to 2014, who represented 0.06% (2 of 3576) of all adult LT patients. RESULTS Mean age of the patients was 42...

Reconstruction of large chest wall defects always demand surgeons of having lots of means available (both materials and resourceful) to apply a cover to chest wall defects which can range from a few centimeters to the lack of a few entire ribs. In this study, we present the case of a teenager who suffered from a complete resection of three ribs because of Ewing sarcoma dependent on the sixth rib. Given the size of the defect, a multidisciplinary approach was chosen to provide rigid and soft tissue coverage and minimal functional and aesthetic impact...

Right umbilical portion (RUP) is a rare congenital anomaly associated with anomalous ramifications of the hepatic vessels and biliary system. As such, major hepatectomy requires a careful approach. We describe the usefulness of the Glissonean approach in two patients with vessel anomalies, such as RUP. The first patient underwent a right anterior sectionectomy for intrahepatic cholangiocarcinoma. We encircled several Glissonean pedicles that entered the right anterior section along the right side of the RUP...

BACKGROUND: Transforaminal lumbar interbody fusion (TLIF) is an effective surgery for lumbar degenerative disease. However, this fusion technique requires resection of inferior facet joint to provide access for superior facet joint resection, which results in reduced lumbar spinal stability and unnecessary trauma. We have previously developed extraforaminal lumbar interbody fusion (ELIF) that can avoid back muscle injury with direct nerve root decompression. This study aims to show that ELIF enhances lumbar spinal stability in comparison to TLIF by comparing lumbar spinal stability of L4-L5 range of motion (ROM) on 12 cadaveric spine specimens after performing TLIF or ELIF...

Osteomas are the most common benign tumors of the paranasal sinuses. They are usually localized in the frontal sinus. Giant osteomas of the frontal sinuses are very rare but readily extend into the intraorbital or intracranial cavity, causing serious complications. This is a report of a 14 year-old boy with a bulging in frontal area and asymptomatic giant osteoma of the frontal sinuses. He had a history of minor trauma that had a bulging after 3 months. However, he referred to a plastic surgeon after 15 months...

BACKGROUND: The incidence of malignant synchronous colorectal tumors (SCRT) is between 2% and 5%, and the association of synchronous adenomatous polyps in colon cancer has been reported to be 15%-50%. Surgical resection is the primary treatment option for SCRT not amendable to endoscopic resection. Lesions in adjacent segments are usually treated with more extensive resection; however, there is still some controversy on how to best treat synchronous lesions in separate segments, especially when the rectum is involved...

BACKGROUND: Cervical ribs have been reported to be present in about 0.5% of the general population, 10% of patients with cervical rib who are symptomatic usually have neurogenic symptoms, but some have arterial symptoms. In 1861, Coote was the first to excise a cervical rib through a supraclavicular approach and relieved the symptoms of thoracic outlet syndrome. OBJECTIVES: in this work we address the efficacy and safety of a modification to the supraclavicular approach for resection of symptomatic cervical ribs...

OBJECTIVE: To present technical details for central hepatectomy and right anterior and posterior sectionectomies using perihilar Glissonian approach for anatomical delineation and selective inflow occlusion. BACKGROUND: Central tumors and those deeply located in the right liver may require extensive resections because of their proximity to major vascular structures. In such cases, anatomical more limited resections such as central hepatectomy or sectionectomies may provide an alternative to extensive surgery by assuring both parenchymal sparing and suitable oncologic resection...

INTRODUCTION: Intracranial enterogenous cysts are rare and mainly occur in the posterior fossa. These cysts are usually extra-axial, midline, anterior to the brainstem, or at the cerebellopontine angle. We report a case of an enterogenous cyst in which diagnosis was difficult because the lesion showed atypical pathologic findings. CASE PRESENTATION: A healthy 41-year-old man complained of paroxysmal occipital headaches lasting over a week, with increased severity for 3 days accompanied by slight dizziness and mild nausea...
