Comparison of Efficacy of Enucleation and Pancreaticoduodenectomy for Small (<3 cm) Branch Duct Type Intraductal Papillary Mucinous Neoplasm Located at the Head of Pancreas and the Uncinate Process

PURPOSE: Accurate indications and the extent of surgery for branch duct intraductal papillary mucinous neoplasm (IPMN) of the pancreas are still debatable. In particular, small tumor is located at the head portion of pancreas presents a dilemma. The purpose of this study is to compare the efficacy of enucleation (EN) with that of pancreaticoduodenectomy (PD) in patients with small (2 cm

Mechanical Bowel Preparation for Elective Colorectal Surgery: A Prospective Randomized Study Comparing Two Liters and Four Liters of Polyethylene Glycol-Based Oral Lavage Solutions

PURPOSE: This study was undertaken to determine whether a mechanical bowel preparation with 2 liters polyethylene glycol solution combined with a Bisacodyl 20 mg (Group II) increases the acceptability of bowel preparation and reduces discomfort compared with 4 liters of polyethylene glycol solution (Group I). METHODS: We conducted a prospective randomized single-blinded study. Eighty patients undergoing an elective colorectal surgery in Severance hospital from April 1999 to September 1999 were included in this study. The patients' tolerance, cleansing ability and surgeon's satisfaction were assessed by a structured questionnaire. Postoperative complications were also evaluated. RESULTS: The patients' tolerance of the group II (2 liters polyethylene glycol solution combined with a Bisacodyl 20 mg) was better than that of the groups I (4 liters of polyethylene glycol solution). The cleaning ability and surgeon's satisfaction were not different between two groups (p=0.225, p=0.322). The incidence of postoperative complications was 2.3 percent in Group I and 2.7 percent in Group II. CONCLUSIONS: The mechanical bowel preparation with two liters of polyethylene glycol solution with a Bisacodyl 20 mg was more comfortable to patients and equally efficient compared with the mechanical bowel preparation with the 4 liters of polyethylene glycol solution regimen before elective colorectal surgery.
