Unusual contribution of the first jejunal vein in the formation of the portal vein.

Jejunum is drained into superior mesenteric vein through a series of jejunal veins. The way in which the first jejunal vein terminates is of great importance in upper abdominal surgery and radiological procedures. Knowledge of its variations is particularly important in surgical procedures like orthotropic hepatic transplantation, hepatic vein reconstruction, pancreatic surgery and surgical procedures of duodenojejunal junction. We saw a first jejunal vein opening directly into the portal vein. Further, the inferior mesenteric vein drained into the first jejunal vein. This case could be useful to gastroenterologists, general surgeons and radiologists.

Complete enclosure of gall bladder inside the lesser omentum - a rare anomaly.

Gall bladder is known for many congenital anomalies such as duplication, intrahepatic position, floating position etc. Most of its anomalies can be detected in ultrasound examination and radiography. We report an extremely rare congenital anomaly of gall bladder as observed in a male cadaver during dissection classes. The gall bladder was totally enclosed in the right free margin of the lesser omentum, in front of the usual contents of the right free margin of lesser omentum. The size, shape and blood supply of the gall bladder were normal. Though this anomaly might not cause any functional disturbances, it might result in complications during laparoscopic cholecystectomy.

Descendens vagohypoglossi: rare variant of the superior root of ansa cervicalis.

Knowledge of variants in the formation and position of the ansa cervicalis is important in head and neck surgery, specifically in reconstructions of the tongue that use the infrahyoid muscles, and in the anastomosis of the ansa cervicalis to the recurrent laryngeal nerve when the laryngeal muscles have been paralysed. We describe a rare variant of the superior root of the ansa cervicalis, which had a contribution from the vagus and hypoglossal nerves. The inferior root was formed by the C2 and C3 ventral rami, but it passed medial to the internal jugular vein before it joined the superior root to form the loop.
