Background: The literature reports 4-10% mortality rate, 30-60% morbidity rate, and 9-29% anastomotic leak rate after pancreaticoduodenectomy (PD) performed for periampullary tumors. These data demonstrate a linear relationship between surgical volume and outcome.
Methods: The objective of this study was to evaluate the experience of a high-volume hospital with low-volume pancreatoduodenectomy for suspected cancer.
Background: The relationship between volume and outcome has been established in the literature for several complex surgical procedures. Improved outcome has been suggested at high-volume hospitals or with high-volume surgeons.
Methods: The objective of this study was to evaluate the experience of a low-volume hospital with major liver resections.
Background: Barrett's esophagus affects 5-10% of patients with gastroesophageal reflux disease (GERD) and is associated with a 40-fold increased risk of malignant transformation. Ablative therapies may lead to esophageal perforation or stricture formation if applied too liberally and residual glandular tissue and persistent cancer risk if utilized too sparingly.
Methods: Ten pigs underwent gastrotomy.
Background: The rapid emergence of laparoscopic surgery over the past decade has highlighted the need for teaching and assessing laparoscopic manipulative skills. Most analyses consist of a measurement of the time to complete a specified task and a subjective assessment by an observer. Objective assessments of accuracy in the performance of manipulative skills have been lacking.

Methods: In athymic rats, 10,000 colon cancer cells were injected intraperitoneally.
