Prevention of incisional hernia with prophylactic onlay and sublay mesh reinforcement versus primary suture only in midline laparotomies (PRIMA): 2-year follow-up of a multicentre, double-blind, randomised controlled trial.

Background: Incisional hernia is a frequent long-term complication after abdominal surgery, with a prevalence greater than 30% in high-risk groups. The aim of the PRIMA trial was to evaluate the effectiveness of mesh reinforcement in high-risk patients, to prevent incisional hernia.

Methods: We did a multicentre, double-blind, randomised controlled trial at 11 hospitals in Austria, Germany, and the Netherlands.

The use of negative-pressure wound therapy in pilonidal sinus disease: a randomized controlled trial comparing negative-pressure wound therapy versus standard open wound care after surgical excision.

Background: Pilonidal sinus disease is associated with significant morbidity after surgical treatment with regard to wound healing. Recent case studies suggested that negative-pressure wound therapy as primary treatment following surgical excision may shorten the duration of wound healing.

Objective: The purpose of this randomized controlled trial was to evaluate the role of vacuum therapy in pilonidal sinus disease: negative-pressure wound therapy versus standard open wound care after surgical excision.

Short-term results of a randomized controlled trial comparing primary suture with primary glued mesh augmentation to prevent incisional hernia.

Background: Incisional hernia is one of the most frequent postoperative complications after abdominal surgery. Patients with an abdominal aortic aneurysm and patients with a body mass index of 27 or higher have an increased risk to develop incisional hernia. Primary mesh augmentation is a method in which the abdominal wall is strengthened to reduce incisional hernia incidence.

Endovenous laser ablation versus conventional surgery in the treatment of small saphenous vein incompetence.

Introduction: In this multicenter, randomized controlled trial, endovenous laser ablation (EVLA) is compared with conventional surgery for the treatment of varicose veins based on incompetence of the small saphenous vein and the saphenopopliteal junction (SPJ).

Methods: In two Dutch hospitals, 189 patients were enrolled and randomized to receive EVLA (810-nm laser) or ligation of the SPJ. End points were success rate measured with duplex ultrasound (6 weeks post-treatment), perioperative pain, quality of life, duration of surgery, difficulty of surgery, complications, cosmetic results, and number of days to resume work and normal activities.

Tissue adhesives in gastrointestinal anastomosis: a systematic review.

Background: Anastomotic leakage in gastrointestinal (GI) surgery remains a major problem. Although numerous studies have been undertaken on the role of tissue adhesives as GI anastomotic sealants, no clear overview has been presented. This systematic review aims to provide a clear overview of recent experimental and clinical research on the sealing of different levels of GI anastomosis with tissue adhesives.

The surgical anatomy of the small saphenous vein and adjacent nerves in relation to endovenous thermal ablation.

Background: Thermal damage to peripheral nerves is a known complication of endovenous thermal ablation (EVA) of the small saphenous vein (SSV). Therefore, the main objective of this anatomic study was to define a safe zone in the lower leg where EVA of the SSV can be performed safely.

Methods: The anatomy of the SSV and adjacent nerves was studied in 20 embalmed human specimens.

Cryo perforator surgery with a diamond dust-coated cryoprobe.

This study was conducted to determine the efficacy of cryoperforator surgery in the treatment of incompetent perforating veins with a diamond dust coated cryoprobe. Eleven patients with clinical severity class C2-C4 were enrolled in this study. Under local anesthesia, incompetent perforating veins were duplex guided treated with a diamond dust coated cryoprobe.

Randomized clinical trial of laparoscopic versus open repair of the perforated peptic ulcer: the LAMA Trial.

Background: Laparoscopic surgery has become popular during the last decade, mainly because it is associated with fewer postoperative complications than the conventional open approach. It remains unclear, however, if this benefit is observed after laparoscopic correction of perforated peptic ulcer (PPU). The goal of the present study was to evaluate whether laparoscopic closure of a PPU is as safe as conventional open correction.

A randomized trial of cryo stripping versus conventional stripping of the great saphenous vein.

Objective: This multicenter randomized clinical trial compared cryo stripping of the great saphenous vein (GSV) with conventional stripping.

Methods: The study randomized 494 patients with symptomatic (CEAP) clinical severity class 2 to 4 to cryo stripping (n = 249) or conventional stripping (n = 245). The primary outcome was residual GSV 6 months after surgery measured by venous duplex ultrasound imaging.

Two-year outcomes after conventional or endovascular repair of abdominal aortic aneurysms.

Background: Two randomized trials have shown better outcomes with elective endovascular repair of abdominal aortic aneurysms than with conventional open repair in the first month after the procedure. We investigated whether this advantage is sustained beyond the perioperative period.

Methods: We conducted a multicenter, randomized trial comparing open repair with endovascular repair in 351 patients who had received a diagnosis of abdominal aortic aneurysm of at least 5 cm in diameter and who were considered suitable candidates for both techniques.
