120-day comparative analysis of adhesion grade and quantity, mesh contraction, and tissue response to a novel omega-3 fatty acid bioabsorbable barrier macroporous mesh after intraperitoneal placement.

Purpose: This study aimed to evaluate adhesion formation, mesh contraction, and tissue response to an omega-3 fatty acid barrier-coated lightweight polypropylene mesh (C-Qur) after intra-abdominal placement, and compare these properties to those of other commercially available meshes.

Materials And Methods: After randomization, 3 x 3 cm pieces of Atrium C-Qur, Mesh ProLite Ultra, Composix, Parietex, Proceed, Sepramesh, and DualMesh were sewn to the intact peritoneum on either side of a midline incision in 41 New Zealand white rabbits. Necropsy was performed at 120 days, and explants were evaluated for adhesion grade, adhesion amount, and mesh contraction.

Outcomes of laparoscopic paraesophageal hernia repair in elderly and high-risk patients.

Background: This study examines the impact of age and comorbidities on complications and outcomes of laparoscopic (Lap) paraesophageal hernia (PEH) repair.

Methods: Data were collected prospectively on all patients who underwent Lap PEH repair from January 1995 through June 2005. Pre- and postoperative variables including complications were analyzed.

Alteration in irrigant flow and deflection of flexible ureteroscopes with nitinol baskets.

Background And Purpose: Introduction of an instrument into the working channel of ureteroscopes adversely affects flow and deflection. We evaluated the alterations in ureteroscope channel flow and deflection caused by available Nitinol(R) baskets.

Materials And Methods: We compared the effects of 11 Nitinol baskets on irrigation flow and deflection of three flexible ureteroscopes (Olympus P3, ACMI DUR8, and ACMI DUR8 Elite).

Comparison of holding strength of suture anchors for hepatic and renal parenchyma.

Background And Purpose: Various laparoscopic devices have been described for suture anchoring during solidorgan parenchymal closure. Application of these devices expedites the closure of parenchymal defects and minimizes ischemia time. We compared different technologies as suture anchors for parenchymal closure.

Perioperative outcomes and complications of laparoscopic ventral hernia repair.

Background: Laparoscopic techniques are being used increasingly in the repair of ventral hernias and offer the potential benefits of a shorter hospital stay, decreased wound complications, and possibly a lower recurrence rate. Despite good results from high-volume centers, significant complications may occur with this approach and the morbidity of incisional hernia repair may be underestimated. The purpose of this study was to review our experience with laparoscopic ventral hernia repair (LVHR) since its inception at our institution.
