Surgical management of large bowel obstruction and significant hepatic displacement caused by Chilaiditi syndrome.

Chilaiditi's sign is the presence of pseudopneumoperitoneum caused by colonic distension and interposition with the liver on radiographic films. Most patients with Chilaiditi's sign are asymptomatic. Chilaiditi's syndrome is defined as the development of abdominal pain or symptoms of bowel obstruction along with the presence of Chilaiditi's sign.

Endovascular repair of a giant common hepatic aneurysm.

Hepatic artery aneurysms are a rare phenomenon but their diagnosis and prompt treatment are imperative due to a high risk of mortality and complications. Appropriate management depends on patient characteristics, anatomical location of the aneurysm, operative risk and collateral arterial supply. Management options include surgical and endovascular approaches.

PET-positive suture granuloma of abdominal wall 56 years post-appendicectomy mimicking recurrence of lymphoma.

We present a unique case of a positron emission tomography (PET)-positive suture granuloma deep to an appendicectomy abdominal wall scar from 56 years prior in a patient with treated lymphoma. The lesion was first detected 8 years ago on a PET scan for new diagnosis of follicular lymphoma, with stable appearances 6 and 7 years later at follow-up. Ultrasound-guided biopsy and flow cytometry of the specimen could not exclude an untreated or recurrent lymphoma; thus, the patient underwent resection of the right iliac fossa abdominal wall lesion.

Laparoscopic choledochoscopy for choledocholithiasis is possible in the anatomical anomaly of left gallbladder.

Laparoscopic cholecystectomy (LC) is more challenging in the anatomical variation of left-sided gallbladder with the anomaly also highly related to biliary anomalies. Therefore, there has been a reluctance to operate close to the common bile duct (CBD) in left gallbladder patients, and thus choledocholithiasis is usually treated with endoscopic retrograde cholangiopancreatography (ERCP). There is emerging evidence that single stage LC and CBD exploration for choledocholithiasis may be superior to two stage LC and ERCP in terms of short-term and long-term morbidity, cost and length of stay.
