We herein report a rare case of solitary splenic metastasis of a pulmonary carcinoid, for which hand-assisted laparoscopic splenectomy was performed. A 73-year-old man was admitted to the Inoue Hospital (Fukuyama, Japan) in March 2015 with an abnormal shadow of the spleen. The patient had a history of right upper lobectomy with lymph node dissection for a pulmonary typical carcinoid (pT1N0M0 st...

A 47-year-old woman presented with an abdominal mass and nausea. Abdominal ultrasound and computed tomography (CT) showed a sausage-shaped mass with invagination. One polyp that appeared to exceed 3 cm was found in the sigmoid colon. Laparoscopy confirmed an intussusception mass, and the intussusception was dissected by hand-assisted laparoscopy (HALS). The sigmoid colon was also mobilized to t...

A 47-year-old man was referred to Seoul National University Bundang Hospital with an ulcerative lesion in the midbody of the stomach. Computed tomography revealed that he was a situs inversus totalis (SIT) patient. Robot-assisted distal gastrectomy with D1+β lymph node dissection and Billroth II anastomosis were performed. With the aid of robotic surgery, the surgeon didn't need to change his p...

Background: Mesenteric venous thrombosis has been a reported rare postoperative complication after laparoscopic surgery and may lead to increased patient morbidity and possible mortality. Methods: We report a case highlighting the postoperative presentation of mesenteric venous thrombosis after laparoscopic robotic-assisted colectomy and its management. Results: We present a case of a 52-year-o...

A software system and database for computer-aided diagnosis with thin-section computed tomographic (CT) images of the chest was designed and implemented. When presented with an unknown query image, the system uses pattern recognition to retrieve visually similar images with known diagnoses from the database. A preliminary validation trial was conducted with 11 volunteers who were asked to selec...

INTRODUCTION Mycobacterium avium complex (MAC) lung disease presenting as a solitary pulmonary nodule (MAC-SPN) is often asymptomatic, is more common in middle to old age, and mimics lung cancer or tuberculoma. We report herein a case of MAC-SPN in an immunocompetent young adult patient, presenting with persistent chest pain and a subacutely progressive nodule with high intense (18)F-fluorodeox...

With increasing numbers of immune-compromised patients with malignancy, hematologic disease, and HIV, as well as those receiving immunosupressive drug regimens for the management of organ transplantation or autoimmune inflammatory conditions, the incidence of fungal infections has dramatically increased over recent years. Definitive diagnosis of pulmonary fungal infections has also been substan...

RATIONALE Understanding the status of internal mammary lymph nodes of breast cancer is critical in the accurate staging of breast cancer and the development of accurate therapeutic regimen for selected patients. Current techniques for dissection of internal mammary lymph node biopsy involve endoscopic or Traditional thoracic surgery, An important drawback of the current techniques is the great ...

The aim of the present study was to report the initial clinical experience of adopting the da Vinci Surgical System (Intuitive Surgical, Inc., Sunnyvale, CA, USA) to perform a retroperitoneal tumor resection. The patient was a 56-year-old female who presented with a five-year history of hypertension. Abdominal dynamic computed tomography (CT) and positron emission tomography-CT scans revealed a...

Esophageal cancer invading the muscularis mucosa sometimes involves regional lymph node metastases. However, lymph node metastases are rare in the dorsal area of the thoracic aorta. We describe a patient with an intramucosal esophageal cancer invading the muscularis mucosa, accompanied by lymph node metastases in the dorsal area of the thoracic aorta. These lesions were successfully resected by...
