Randomized Controlled Trial Multicenter Study
Laparoscopic repair of very large hiatus hernia with sutures versus absorbable mesh versus nonabsorbable mesh: a randomized controlled trial.
Determine whether absorbable or nonabsorbable mesh in repair of large hiatus hernias reduces the risk of recurrence, compared with suture repair. ⋯ No significant differences were seen for recurrent hiatus hernia, and the clinical differences were unlikely to be clinically significant. Overall outcomes after sutured repair were similar to mesh repair.

Multicenter Study Clinical Trial
A step toward NOTES total mesorectal excision for rectal cancer: endoscopic transanal proctectomy.
Previous publications have suggested that endoscopic transanal proctectomy (ETAP) is a promising technique and may be an alternative to conventional low anterior resection for rectal cancer. The aim of this study was to evaluate the technical feasibility of ETAP, with a particular focus on postoperative and oncological results and on functional outcomes. ⋯ ETAP is a feasible alternative surgical option to conventional laparoscopy for rectal resection and may represent a promising step toward rectal natural orifice transluminal endoscopic surgery (NOTES).

Multicenter Study
Management of biliary cystic tumors: a multi-institutional analysis of a rare liver tumor.
To characterize clinical and radiological features associated with biliary cystic tumors (BCTs) of the liver, and to define recurrence-free and overall survival. ⋯ Among patients undergoing surgery for BCT, associated malignancy was uncommon (10%) and no preoperative findings reliably predicted underlying BCAC. After excision of BCA, long-term outcomes were good; however, patients with BCAC had a worse long-term prognosis.

To explore the reliability and validity of the Objective Structured Assessment of Ultrasound Skills (OSAUS) scale for point-of-care ultrasonography (POC US) performance. ⋯ This study demonstrates high reliability as well as evidence of construct validity of the OSAUS scale for assessment of POC US competence. Hence, the OSAUS scale may be suitable for both in-training as well as end-of-training assessment.

Comparative Study Clinical Trial
Transanal total mesorectal excision in rectal cancer: short-term outcomes in comparison with laparoscopic surgery.
The aim of this study was to compare short-term results obtained with transanal total mesorectal excision (TME) and laparoscopic surgery. ⋯ Evaluation of short-term outcomes demonstrated that transanal TME is a feasible and safe technique associated with a shorter surgical time and a lower early readmission rate.
