Case Reports
Laparoscopic resection of intestinal stromal tumors with transrectal extract specimen: A case report.
Small intestine stromal tumors (SISTs) are a type of gastrointestinal stromal tumor (GIST) that has an insidious onset. Natural orifice specimen extraction (NOSE) surgery has been gradually developed for the treatment of colorectal, stomach, small intestine, hepatobiliary, and gynecological tumors because of its safety and feasibility. This case study explored the possibility of applying the NOSE method for the treatment of SIST. ⋯ Nose surgery is minimally invasive, results in patient recuperation with no complications, and is considered to be feasible for SIST treatment.

Case Reports
A large pheochromocytoma requiring aortic and inferior vena caval reconstruction: A case report.
It is difficult to discriminate malignant pheochromocytoma (PCC) from benign PCC. The requirement of abdominal aortic and inferior vena cava reconstruction is extremely rare. ⋯ The complete resection of the tumor and infiltrated great vessels were necessary for the long-term survival of patients with a large PCC. The ePTFE graft is a good substitute for vessel reconstruction.

Case Reports
Cauda equina syndrome without motor dysfunction following lumbar spinal stenosis surgery: A case report.
Cauda equina syndrome (CES) refers to a group of symptoms that occur when the nerves in the cauda equina become compressed or damaged. The most common etiology of CES is lumbar intervertebral disc herniation, but CES following lumbar spinal surgery is rare, especially without motor dysfunction. Herein, we illustrate a case of CES that developed as a complication of spinal surgery and to deduce its possible underlying cause. ⋯ CES as a complication of lumbar spinal surgery is very rare. Excessive sensitivity to the traction of the dural sac was, in our opinion, the most possible cause of postoperative CES in this case. When the nerve root is pulled intraoperatively, it is best not to cross the central line of the spinous process. The plane of the nerve retractor needs to be parallel to the dural sac at the pulling point to reduce the formation of shear force. Most importantly, gentle maneuver is required because sensitivity to the traction of the dural sac varies individually.

Case Reports
Ultrasonographic imaging of calcifying fibrous tumor of cervical esophagus: A case report.
Calcifying fibrous tumor (CFT) is a rare benign mesenchymal tumor characterized by cytologically benign fibroblasts that produce abundant collagen with scattered lymphocytes, plasma cells, and psammomatous or dystrophic calcifications. ⋯ Although imaging diagnosis of CFT is difficult, the findings of clear border, coarse calcification on conventional ultrasound and peripheral hypoenhancement without central enhancement on contrast-enhanced ultrasound (CEUS), together with real-time evaluation of the relationship between the tumor and esophagus help to distinguish CFT of cervical esophagus from other lesions in the neck.

Acute pulmonary thromboembolism caused by factor V Leiden mutation in South Korea: A case report.
Although Factor V Leiden (FVL) mutation is a major cause of inherited thrombophilia in Western populations; the mutation is extremely rare in Asia. ⋯ FVL mutation screening may be considered in Asian patients with thrombophilia of uncertain etiology in the future.
