Application of laparoscopic distal pancreatectomy for normal anatomy after hiatal hernia repair: A case report.

We describe a case of pancreatic tumor associated with a giant type IV hiatal hernia that had prolapsed into the posterior mediastinum. Hiatal hernia repair should be performed first because it enables laparoscopic distal pancreatectomy to be performed in the normal anatomical position.

A case of retroperitoneal abscess caused by infection of urachal remnant.

Infection of urachal remnant may cause recurrent abscesses. In the current case report, we describe a urachal remnant infection leading to a retroperitoneal abscess, which is an extremely rare condition. In such cases, the recommended treatment is urachal remnant resection.

Aberrant common hepatic artery from the left gastric artery and with no connection to the gastroduodenal artery: Risky vascular anomaly in gastrectomy.

Knowledge of anatomical variations of the celiac axis is important in upper abdominal surgery. Aberrant common hepatic artery originating from the left gastric artery without connecting the gastroduodenal artery is extremely rare. Preoperative vascular anatomy assessment using reconstructions of CT images may be useful for safe surgical procedure.
