Impact of previous gastric or colonic resection on polyethylene glycol bowel preparation for colonoscopy.

Introduction: Adequate bowel preparation is essential for successful completion of colonoscopy. This study examines whether previous bowel resection affects the quality of bowel preparation.

Methods: This study prospectively included patients who had gastric or colonic resection (bowel resection group, n = 92) and a control group (n = 92).

Risk factors associated with the postoperative recurrence of intraductal papillary mucinous neoplasms of the pancreas.

Objectives: The risk factors correlated with the post-operative recurrence of intraductal papillary mucinous neoplasms (IPMNs) of the pancreas are not well established. The aim was to determine the risk factors of recurrence.

Methods: We reviewed retrospectively the differences of clinicopathologic features between the recurrence and nonrecurrence groups of patients with IPMN who underwent surgical resection and analyzed the recurrence-related factors.
