The laparoscopic adjustable gastric band (LAGB) was approved for use in the US in 2001 and has been found to be a safe and effective surgical treatment for morbid obesity. However, there is a recent trend toward reduced use of LAGB nationwide. The objective of this study was to examine the prevalence and outcomes of primary LAGB implantation compared with revision and explantation at academic centers. ⋯ Since 2013, the number of gastric band explantation procedures has exceeded that of implantation procedures at academic centers. Laparoscopic adjustable gastric band revision or explantation is associated with longer length of stay, higher rate of postoperative ICU admissions, and higher overall morbidity compared with LAGB implantation.

Surgical site infections (SSI) are a common complication after colorectal surgery. An infection prevention bundle (IPB) was implemented to improve outcomes. ⋯ Implementation of an IPB was successful in decreasing SSI rates in colorectal surgery patients. The combination of oral antibiotics with a mechanical bowel preparation was the strongest predictor of decreased SSI.

Delayed gastric emptying (DGE) is a common serious problem after pancreaticoduodenectomy (PD). Flange gastrojejunostomy (FL-GE) is a previously described technique that creates an internal flange in a hand-sewn gastroenterostomy. Results of FL-GE on incidence and severity of DGE after PD are presented. ⋯ In this cohort study, the flange technique was associated with a marked reduction in the incidence of DGE after PD.

Prostaglandin E2: A Pancreatic Fluid Biomarker of Intraductal Papillary Mucinous Neoplasm Dysplasia.
With the increased frequency of diagnostic imaging, pancreatic cysts are now detected in >3% of American adults. Most of these are intraductal papillary mucinous neoplasms (IPMNs) with well-established but variable malignant potential. A biomarker that predicts malignant potential or dysplastic grade would help determine which IPMNs require removal and which can be observed safely. We previously reported that pancreatic fluid prostaglandin E2 (PGE2) levels might have promise as a predictor of IPMN dysplasia and we seek to validate those results in the current study. ⋯ Our results validate pancreatic cyst fluid PGE2 as an indicator of IPMN dysplasia, especially in select patients with preoperative pancreatic cyst fluid CEA >192 ng/mL. The inclusion of PGE2/CEA in a diagnostic biomarker panel can facilitate more optimal treatment stratification of IPMN patients.

Postoperative hypophosphatemia is common and is associated with a lower risk of liver failure after hepatectomy, but higher morbidity after pancreatectomy. Whether different physiologic mechanisms underlie the hypophosphatemia associated with these very different clinical outcomes is unclear. This study aims to evaluate the underlying mechanism in postoperative hypophosphatemia. ⋯ This study demonstrates that the mechanism of hypophosphatemia is the same for both liver and pancreas resections. Postoperative hypophosphatemia is associated with increased NAMPT. The mechanism that upregulates NAMPT and its role on disparate clinical outcomes in postoperative patients warrant additional investigation.
