BACKGROUND: Magnetic compression anastomosis (magnamosis) uses a pair of self-centering magnetic Harrison Rings to create an intestinal anastomosis without sutures or staples. We report the first-in-human case series using this unique device. STUDY DESIGN: We conducted a prospective, single-center, first-in-human pilot trial to evaluate the feasibility and safety of creating an intestinal anastomosis using the Magnamosis device. Adult patients requiring any intestinal anastomosis to restore bowel continuity were eligible for inclusion...

BACKGROUND: Parastomal hernia repair (PHR) remains a challenge with no optimal repair technique. During retromuscular hernia repair, traversing the stomal conduit through the abdominal wall can result in angulation and compression. Widening of traditional cruciate incisions in mesh and/or fascia likely contributes to recurrences. To address these pitfalls, the Stapled Transabdominal Ostomy Reinforcement with Retromuscular Mesh (STORRM) technique utilizing a circular stapler was developed...

BACKGROUND: Anastomotic leakage following colorectal resection remains one of the most significant complications with relevant morbidity and mortality. There is evidence that a higher number of stapler firings for rectal division can affect the leak rate in double stapling anastomosis. However, there are no data concerning compression anastomosis. We present our institutional experience addressing this issue. DESIGN: This is a retrospective review of a prospective institutional database of patients undergoing colonic and rectal resection for benign and malignant indications between January 2008 and December 2014 at the surgical department of the St...

BACKGROUND: Compression anastomosis has been recently abandoned because of a nonsuperiority compared to stapling anastomosis. Nonremoval of the rings has frequently been reported and this technique does not support a routine use. The aim of this experimental study was to assess the feasibility of anastomosis using compression with a device consisting of fragmented rings. METHODS: A new compression device, the "Anastocom," was compared to standard double-stapled colocolonic anastomosis in 2 groups of 8 pigs...

Anastomotic leak following colorectal surgery can be a devastating adverse event. The ideal stapling device should be capable of rapid creation of an anastomosis with serosal apposition without the persistence of a foreign body or a foreign body reaction which potentially contribute to early anastomotic dehiscence or late anastomotic stricture. A systematic review was performed examining available data on controlled randomized and non-randomized trials assessing the NiTi compression anastomosis ring-(NiTi CAR™) (NiTi Solutions, Netanyah Israel) in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) standards...

BACKGROUND: Anterior cervical discectomy and fusion is currently the most commonly used technique in cervical surgery. But the implantation of a traditional plate is time-consuming and exposes the patient to additional adverse events. In this study, we analyzed results in patients who underwent anterior cervical discectomy and fusion with C-JAWS fixation. The C-JAWS device is a new cervical compressive staple developed to stabilize the spacer. METHODS: At our department, between January 2012 and December 2013, nine consecutive patients with cervical spondylopathy underwent an anterior cervical discectomy and fusion process in which we used a polyether ether ketone cervical spacer prefilled with bone substitute and secured with a cervical compressive staple...

Postoperative pancreatic fistulas represent the most frequent complication after distal and segmental pancreatectomy and occur with a frequency of up to 50 %. There are many technical variations of pancreatic stump treatment for reduction of fistula rates after distal resection. Most of these techniques have only been analyzed in retrospective studies and the evidence for or against a specific technique is low. Several retrospective trials have been conducted with good results to compare suturing with stapled closure of the remnant and to assess the effect of a vascularized falciform ligament patch in reducing postoperative pancreatic fistula; however, in a recently published randomized trial, which analyzed closure of the remnant with a pancreaticojejunostomy compared to standard closure, these results could not be confirmed...

Anastomotic leaks are a feared complication of colorectal resections and novel techniques that have the potential to decrease them are still sought. This study aimed to compare the anastomotic leak rates in patients undergoing compression anastomoses versus hand-sewn or stapled anastomoses. Randomized controlled trials (RCTs) comparing outcomes of compression versus conventional (hand-sewn and stapled) colorectal anastomosis were collected from MEDLINE, Embase and the Cochrane Library. The quality of the RCTs and the potential risk of bias were assessed...
