Anterior posterior resection

Giancarlo D'Andrea, Giovanni Sessa, Veronica Picotti, Antonino Raco
We report the case of a large lumbar schwannoma eroding the vertebra and originating from spinal canal with invasion of the retroperitoneal space. We also review all the cases in literature reporting lumbar schwannomas eroding the vertebral bodies and invading the retroperitoneal space focusing on the surgical strategies to manage them. Spinal CT-scan revealed a 44 mm × 55 mm inhomogeneous soft-tissue mass arising from the right L5-S1 neural foramen and its most anterior portion had a clear colliquative aspect...

INTRODUCTION: Polymethylmethacrylate (PMMA) cement is useful for spinal reconstruction, but can cause complications including new vertebral fractures, neurological disorders and pulmonary embolism. We report a case in PMMA cement used for spinal reconstruction after tumor curettage dislodged and penetrated the gastrointestinal tract. DIAGNOSES: The patient was diagnosed with a retroperitoneal extragonadal germ cell tumor at age 27 years. After chemotherapy and tumor resection, the tumor remained...

With an increasingly aging population, adult spinal deformity is becoming more common. This can be associated with increased morbidity. Results from multicentre studies of deformity surgery correction confirm complication rates as high as 40 percent. Most often a bad result is associated with inadequate restoration of the sagittal balance. Posterior vertebral body resection has been described as a method to correct significant deformity, but this is a complicated procedure. It is possible to do this in the thoracic spine where nerve roots can be sacrificed, but it is difficult in the lumbar spine due to the significant role of the lumbar nerve roots...

Rehabilitation of mandibular resection poses functional, esthetic, and psychological challenges. The deviation and rotation of the mandible toward the resected side leaves the patient with almost no option of chewing. This is aggravated if the patient is edentulous. The case report discussed in this article was an edentulous patient taken up with the primary goal to limit deviation toward resected side and provide a stable and retentive prosthesis to the patient. Two implants were placed anteriorly, splinted with bar and clip supported superstructure...

BACKGROUND: Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) allows R0 resection even for patients with extremely small future liver remnants. The ALPPS procedure was initially described for two-stage right trisectionectomy. Reversal ALPPS is a denomination in which the future liver remnant is the right posterior section of the liver. PATIENT: A 42-year-old woman with colorectal metastases in all segments except segment 1 underwent chemotherapy with objective response and was referred for surgical treatment...

PURPOSE: Metastatic epidural spinal cord compression (MESCC) often requires anterior-posterior decompression and stabilization. To reduce approach-related complications, single-stage posterolateral vertebrectomy and 360° fusion is often performed. However, a sufficient reduction of kyphotic deformity through this approach has not been reported. The purpose of this study is to investigate the efficacy of kyphotic deformity reduction by this approach in MESCC. METHODS: A retrospective analysis and chart review was performed for 14 consecutive patients who underwent a vertebrectomy and decompression from a posterolateral approach...

OBJECTIVE: The relationship between functional and structural measurements is of fundamental importance in monitoring treatment and progression in patients with pituitary adenoma. In the present study, we examined the association between longitudinal changes in standard automated perimetry (SAP), retinal nerve fiber layer (RNFL) thickness and multifocal visual evoked potential (mfVEP) amplitude after transsphenoidal surgery. METHODS: Thirty patients with pituitary adenoma were recruited from Huashan Hospital between September 2010 and January 2014...

Spinal involvement occurs frequently in cases of eosinophilic granuloma (EG), but surgical treatment is limited primarily to those with spinal instability. Involvement of the cervical spine is rare, but primarily occurs in the vertebral bodies, and is normally amenable to anterior corpectomy and spinal reconstruction. The authors describe a 27-year-old man with pathologically proven EG who presented with complete destruction of the C-1 lateral mass requiring spinal stabilization. A titanium expandable cage was used to reconstruct the weight-bearing column from the occipital condyle to the superior articular surface of C-2 from a posterior approach, with preservation of the traversing vertebral artery...

PURPOSE: The generation and tissue origination of disc-associated axial pain is still under exploration. This study was performed to evaluate disc-associated axial pain and to explore whether it originates in the disc or its surrounding components. METHODS: A 6-year series of 88 single-level Smith-Robinson disc and posterior longitudinal ligament (PLL) resections performed to treat single-level cervical spondylotic myelopathy was retrospectively examined. All single-level anterior disc decompressions were performed under local infiltration anesthesia; the PLL was not anesthetized to avoid cervical cord block...

Superior hypogastric plexus (SHG) contains mainly sympathetic and most probably also postganglionic parasympathetic fibers. Thus, surgical damage of SHG may cause autonomic pelvic organ dysfunction (Kraima et al., 2015). As already shown for rectal cancer, preservation of the autonomic nerves is facilitated by robotic surgery and may avoid sexual dysfunctions and voiding disorders (Kim et al., 2015). In this educational video, we demonstrate left lower paraaortic lymph node dissection preserving the SHG using ICG fluorescence to label the lymphatic compartment...

Objective: The aim was to explore the strategy and clinical value of laparoscopic transection of median hepatic fissure (MHF) in difficult laparoscopic liver resections. Methods: First the MHF was located and marked, then the transection plane of the MHF was set. Next, the laparoscopic Multifuctional Operative Dissector (LPMOD) and the technique of curettage and aspiration were utilized to transect the liver beginning from the middle portion of the gallbladder fossa, in a caudal-to-cranial and anterior-to-posterior direction, until the clear exposure of the anterior surface of the intrahepatic inferior vena cava...

BACKGROUND: Over the past decade, the treatment of complex intradural and extradural pathologies via expanded endonasal approaches has been made possible by progresses and refinements in skull base reconstruction techniques. The aim of this anatomic study is to describe a novel endonasal flap, the turbinal flap (TF), based on the middle and superior turbinate mucosa and pedicled on the ethmoidal arteries system. METHODS: Three fresh-frozen (6 sides) cadaver heads previously injected with colored silicone were dissected...

BACKGROUND: Due to their important size and complex localization, the management of thoracic dumbbell tumors is challenging, frequently requiring the need for an anterior approach. Our study aims to first report the feasibility and safety of a single-stage posterior minimally invasive procedure in achieving complete resection of voluminous thoracic dumbbell tumors. METHODS: We retrospectively reviewed the medical records of five consecutive patients, who underwent the minimally invasive resection of a type III thoracic dumbbell tumor in our institution between March 2007 and March 2012...

BACKGROUND: Surgical treatment for pincer femoroacetabular impingement (FAI) of the hip remains controversial, between trimming the prominent acetabular rim and reverse periacetabular osteotomy (PAO) that reorients the acetabulum. However, rim trimming may decrease articular surface size to a critical threshold where increased joint contact forces lead to joint degeneration. Therefore, knowledge of how much acetabular articular cartilage is available for resection is important when evaluating between the two surgical options...

This paper presents a highly challenging technique involving posterior double vertebral column resections (VCRs) and satellite rods placement. This was a young adult case with severe angular thoracolumbar kyphosis of 101 degrees, secondary to anterior segmentation failure from T11 to L1 . There were hemivertebrae at T11 and T12 , and a wedged vertebra at L1 . He received double VCRs at T12 and T11 and instrumented fusion from T6 to L4 via a posterior only approach. Autologous grafts and a cage were placed between the bony surfaces of the osteotomy gap...

BACKGROUND: Single-port video-assisted thoracoscopic surgery (VATS) left upper lobectomy is difficult amongst all the lobes. At the beginning of single-port lobectomies, the upper lobes were believed not to be amenable for single-port approach due to the difficult angulation for staplers. Gonzalez reported the first single-port VATS left upper lobectomy in 2011. METHODS: We report a new technique of single-port VATS left upper lobectomy with the concept of "reverse direction"...

PURPOSE: Recurrent trachea-esophageal fistula (recTEF) is a frequent (5%-10%) complication of congenital TEF (conTEF) and esophageal atresia (EA) repair. In addition, postoperative acquired TEF (acqTEF) can occur in addition to or even in the absence of prior conTEF in the setting of esophageal anastomotic complications. Reliable repair often proves difficult by endoluminal or standard surgical techniques. We present the results of an approach that reliably identifies the TEF and facilitates airway closure as well as repair of associated tracheal and esophageal problems...

OBJECTIVE: Intracranial infectious aneurysms (IIAs) are a rare clinical entity without a definitive treatment guideline. In this study, we evaluate the treatment options of these lesions based on our own clinical experience and review the current knowledge of therapy as portrayed in the literature. METHODS: We conducted a single-center retrospective analysis of all patients with an IIA and performed a systematic review of the literature using the MEDLINE database...

The surgical term "turbinectomy" encompasses many variations in the location and extent of removal. As a systemic approach to consider the negative impact of middle turbinectomy(MT), such as the excessive removal of turbinate, airflows inside a pre-surgery model and a series of virtual surgery models were numerically analyzed and compared. These models simulate three variations of partial MT(three bilateral and three unilateral) with varying resection volume and location. Each middle turbinectomy results in alterations of flow and thermal parameters, such as nasal resistance (NR), velocity, temperature, wall shear stress(WSS) and wall heat transfer(WHT)...
