To systematically determine the imaging findings for distinguishing malignant and benign branch-duct type intraductal papillary mucinous neoplasms (BD-IPMNs), including mixed type, and their diagnostic value through meta-analysis of published studies. ⋯ Presence of mural nodules should be regarded highly suspicious for malignancy warranting a surgical excision whereas cyst size greater than 3 cm, MPD dilatation (5-9 mm), or thick septum/wall may better be managed by careful observation and/or further evaluation.

Randomized Controlled Trial
A prospective, randomized, noninferiority trial of steroid dosing after major colorectal surgery.
To evaluate the safety of perioperative low-dose steroids (LDS) versus high-dose steroids (HDS) in steroid-treated patients with inflammatory bowel disease (IBD) undergoing major colorectal surgery. ⋯ In IBD patients undergoing abdominal surgery, the incidence of postural hypotension or adrenal insufficiency is similar among those receiving high doses or low doses of corticosteroids in the perioperative period. To reduce complications associated with unnecessarily high doses of steroids, steroid-treated IBD patients undergoing major colorectal surgery should be treated with low doses of steroids in the perioperative period. (Clinicaltrials.gov ID# NCT01559675).

Comparative Study
Comparative operative outcomes of early and delayed cholecystectomy for acute cholecystitis: a population-based propensity score analysis.
To compare the operative outcomes of early and delayed cholecystectomy for acute cholecystitis. ⋯ These results support the benefit of early overdelayed cholecystectomy for patients with acute cholecystitis.

Completely laparoscopic gastrectomy with intracorporeal anastomosis was introduced to achieve safer anastomosis and smaller scars. Although several reports have shown the feasibility of linear-stapled anastomosis, there are no studies of a large number of patients assessing the long-term complications and functional outcomes. ⋯ Completely laparoscopic gastrectomy with linear-stapled anastomosis is a feasible choice for gastric cancer patients with some potential long-term advantages such as less anastomotic stenosis and fewer adhesive intestinal obstructions.

To clarify the clinical significance of resection of lymph node metastases in patients' hepatocellular carcinoma (HCC). ⋯ The prognosis of patients with histologically node-positive HCC was similar to that of patients with locally advanced HCC (stage IVA), which supports the validity of the current Japanese staging system and also partially validates the system proposed by the UICC/AJCC.
