Randomized Controlled Trial Multicenter Study
TEP under general anesthesia is superior to Lichtenstein under local anesthesia in terms of pain 6 weeks after surgery: results from a randomized clinical trial.
Persistent pain is common after inguinal hernia repair. The methods of surgery and anesthesia influence the risk. Local anesthesia and laparoscopic procedures reduce the risk for postoperative pain in different time perspectives. The aim of this study was to compare open Lichtenstein repair under local anesthesia (LLA) with laparoscopic total extraperitoneal repair (TEP) with respect to postoperative pain. ⋯ Patients who underwent the laparoscopic TEP procedure suffered less pain 6 weeks after inguinal hernia repair than those who underwent LLA. Groin pain affected the LLA patients' ability to perform strenuous activities such as sports more than TEP patients.

Multicenter Study
Grading of complications and risk factor evaluation in laparoscopic colorectal surgery.
A grading system for postoperative complications is important for quality control and comparison among investigations. The objective of the current study was to evaluate complications associated with laparoscopic colorectal surgery according to a standardized grading system, and to examine risk factors associated with different complication grades. ⋯ This study demonstrates the use of a uniform grading system for complications in laparoscopic colorectal surgery. Conversion was found to be associated with all grades of complications.

Multicenter Study Clinical Trial
Feasibility and yield of a novel 22-gauge histology EUS needle in patients with pancreatic masses: a multicenter prospective cohort study.
The option of obtaining tissue samples for histological examination during endoscopic ultrasound (EUS) has theoretical and practical advantages over cytology alone. The aim of this study was to evaluate the feasibility, yield, and diagnostic accuracy of a new EUS 22-G fine-needle biopsy (FNB) device in patients with solid pancreatic masses in a multicenter, prospective study. ⋯ EUS-FNB was technically feasible in 98 % of patients with a solid pancreatic mass. A suitable sample for histological evaluation was obtained in 88.5 % of the cases after only one single needle pass. The apparently low negative predictive value is likely to be improved by increasing the number of needle passes.
