Laparoscopic Repair of Right Paraduodenal Hernia in Adult Patients: Case Report and Literature Review.

A 56-year-old Japanese female presented with vomiting, nausea, and abdominal pain after excessive drinking and eating. Abdominal computed tomography showed an encapsulated circumscribed cluster of jejunal loops in the right upper quadrant. She was diagnosed with a strangulated intestinal obstruction caused by right paraduodenal hernia (PDH) and underwent an emergency laparoscopic repair.

Successful Use of a Multidisciplinary Approach to Treat a Perforated Duodenal Malignant Lymphoma in an Elderly Patient.

Treatment of duodenal malignant lymphoma is difficult due to life-threatening complications such as intestinal obstruction, perforation, and pancreatitis. Thus, multidisciplinary procedures are required alongside surgical intervention. Contrast abdominal CT images of a 75-year-old female suffering from vomiting revealed thickening of the duodenal wall (from the second to third segment).

Unique extralobar sequestration with atypical location and aberrant vessels.

We report a unique extralobar pulmonary sequestration in the upper thoracic region with 3 aberrant vessels connecting to the right subclavian artery, right superior pulmonary vein, and right pulmonary artery in a 20-year-old man. The sequestered lung was completely excised using a video-assisted thoracoscopic approach.

[Plasmacytoma of chest wall].

We report a 70-year-old man who suffered from right anterior chest wall tumor. Physical examination revealed an elastic hard mass at the right 4th rib measured 6 cm in diameter. Chest X-ray and computed tomography (CT) revealed enhanced mass and destruction of the 4th rib.

Huge mediastinal cystic tumor penetrating the sternum.

We report a very rare case of a huge anterior mediastinal tumor penetrating the sternum that was diagnosed in a 59-year-old woman. The tumor was completely resected en bloc with the manubrium sterni, and the chest wall defect was closed with a pectoralis major muscle flap. Histologic examination of the cystic mass revealed the diagnosis of a benign mediastinal cystic tumor, most likely a benign cystic mature teratoma.
