The jejunum and ileum have been retracted to the left. The transverse colon has been elevated. The peritoneum which covered the right side of the mesentery has been removed to expose the underlying lymphatic structures. Similarly, the peritoneum which extends laterally to the ascending colon as well as the inferior peritoneal layer of the transverse mesocolon have been dissected.
