The pancreaticoduodenectomy, commonly referred to as the Whipple resection, is the en bloc surgical resection of the pancreas head and uncinate process, duodenum, gallbladder, common bile duct, and common hepatic duct just proximal to the cystic duct takeoff with (conventional) or without (pylorus-sparing) the gastric antrum. Although generally an oncologic procedure, the Whipple resection can ...

Chordomas are rare, benign tumors that account for 1-4% of bony lesions and most frequently occur in the skull base, mobile spine, and sacrum. Historically, they have been most effectively managed with en bloc surgical resection, as they are resistant to conventional radiotherapy and chemotherapy. Currently, the gold standard treatment for spinal chordomas is en bloc excision with negative marg...

En bloc resection is the treatment of choice for localized pancreatic cancer. While the perioperative mortality associated with resection is low, it still carries a significant morbidity rate of up to 50% in certain high-risk subsets of patients. With advances in perioperative care, radical resection with inclusion of adjacent vascular structure to achieve negative margin status can be performe...

Renal cell carcinoma (RCC) is rare but aggressive, with greater than 20% of patients presenting with stage III or IV, disease. Surgical resection of the primary tumor regardless of stage is the treatment of choice, and en bloc resection of involved organs provides the only potential chance for cure. This case report describes a patient with metastatic right-sided RCC with invasion of the inferi...

We describe successful vertebrectomy from a posterior approach using a computed tomography (CT)-based navigation system (O-arm) in a 53-year-old man with adenocarcinoma of the posterior apex of the right lung with invasion of the adjacent rib, thoracic wall, and T2 and T3 vertebral bodies. En bloc partial vertebrectomy for lung cancer adjacent to the thoracic spine was planned using O-arm. Firs...

A 71-year-old man was referred for an anterior chest wall mass. Chest computed tomography (CT) and positron emission tomography-CT suggested a malignant tumor. Surgical biopsy through a vertical subxiphoid incision revealed an extra-gastrointestinal stromal tumor (EGIST). En bloc resection of the tumor, including partial resection of the sternum, costal cartilage, pericardium, diaphragm, and pe...

OBJECTIVE To review the indication of surgical treatment of solitary proximal end of femur osteochondromas, and present our experience as regards the approach for a complete and safe resection. MATERIAL AND METHOD A retrospective study of a series of 6 symptomatic solitary proximal end of femur osteochondromas treated by en bloc resection by means of a single anterior or posterior-lateral app...

BACKGROUND Transurethral resection of bladder tumor (TURBT) technique has been considered the routine method for removing most bladder tumors for decades. In contrast, endoscopic submucosal dissection (ESD) is the gold-standard treatment for gastrointestinal superficial tumors. We investigated the effectiveness and applicability of a new technique for en bloc bladder tumor resection using ESD p...
