Abstract
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. Pooled odds ratios (OR) were calculated for categorical outcomes and weighted mean differences for continuous data. Ten RCTs were included, comprising 1969 patients (752 sutured, 225 stapled, and 992 compression anastomoses). Most used the biofragmentable anastomotic ring. There was no significant difference between the two groups in terms of anastomotic leak rates (OR 0.80, 95 % confidence interval (CI) 0.47, 1.37; p = 0.42), stricture (OR 0.54: 95 % CI 0.18, 1.64; p = 0.28) or mortality (OR 0.70; 95 % CI 0.39, 1.26; p = 0.24). Compression anastomosis was associated with an earlier return of bowel function: 1.02 (95 % CI 1.37, 0.66) days earlier (p < 0.001) and a shorter postoperative stay; 1.13 (95 % CI 1.52, 0.74) days shorter (p < 0.001), but significant heterogeneity among studies was observed. There was an increased risk of postoperative bowel obstruction in the compression group (OR 1.87; 95 % CI 1.07, 3.26; p = 0.03). There was no significant difference in wound-related and general complications, or length of surgery. Compression devices do not appear to provide an advantage over conventional techniques in fashioning colorectal anastomoses and are associated with an increased risk of bowel obstruction.

Abstract
The purpose of this study was to determine whether the characteristics of compression anastomoses created by a new device are comparable to existing stapler technology. A total of 18 pigs were studied, and each served as its own control using a 27-mm compression device and a 29-mm stapler. Anastomoses were randomized to proximal and distal positions along the rectum and were separated by 10 cm. Six nonsurvival pigs were sacrificed at zero time to failure test the anastomoses. Twelve pigs were sacrificed at 14 days. Failure pressures, circumferences, and radiographic leak rates were determined. Anastomotic tissue was processed for matrix metalloproteinase, collagen, and elastin levels. The compression anastomoses had higher mean failure pressures than stapled anastomoses at zero time (103 vs 29.9 mm Hg). At 2 weeks, there was no difference between failure pressures (256 vs 250 mm Hg). During burst testing, 3 of the compression anastomoses failed at the anastomosis at 2 weeks, whereas none of the stapled anastomoses failed. The mean anastomotic circumference of the compression anastomoses was narrower than the stapled anastomoses (9.63 vs 11.25 cm, P = .001). There were no clinical leaks or radiographic leaks by barium enema at 2 weeks. There was no difference between matrix metalloproteinase, collagen, or elastin content based on tissue analysis. There were dense adhesions to 7 of 12 (58.3%) of the stapled anastomoses, whereas only 1 of 12 (8.3%) of the compression anastomoses had flimsy adhesions. A new compression anastomosis technique using a nickel-titanium alloy may be an advance in technology by reducing leaks and eliminating foreign material in the anastomosis.

Compression anastomotic ring-locking procedure (CARP) is a safe and effective method for intestinal anastomoses following left-sided colonic resection. Int J Colorectal Dis 2015; 30:969-75.

Abstract
BACKGROUND Compression anastomotic ring-locking procedure (CARP) is a novel procedure for creating colonic anastomoses. The surgical procedure allows perioperative quantification of the compression pressure between the intestinal ends within the anastomosis and postoperative monitoring of the anastomotic integrity. We have recently shown that CARP is a safe and effective method for colonic anastomoses in pigs, and the purpose of the present study was to evaluate CARP for colonic anastomoses in humans. MATERIALS AND METHODS This is a prospective study on 25 patients undergoing elective left-sided colonic resection. Time for evacuation of the anastomotic rings, perioperative compression pressure, and adverse effects were recorded. Postoperative blood samples were collected daily, and flexible sigmoidoscopy was performed 8-12 weeks after surgery to examine the anastomoses. RESULTS Fourteen out of 25 patients underwent CARP. CARP was not used in 11 patients due to advanced tumor disease (two cases) and size restrictions (nine cases). No case of anastomotic leakage, bowel obstruction, or stenosis formation was observed. No device-related perioperative adverse events were noted. The surgical device evacuated spontaneously in all patients by the natural route after a median of 10 days. Perioperative compression pressure ranged between 85 and 280 mBar (median 130 mBar). Flexible sigmoidoscopy revealed smooth anastomoses without signs of pathological inflammation or stenosis in all cases. CONCLUSION Our results indicate that the novel suture-less CARP is a safe and effective method for creating colonic anastomoses. Further studies are warranted in larger patient populations to compare CARP head-on-head with stapled and/or hand-sewn colonic anastomoses.

Abstract
BACKGROUND The biofragmentable anastomotic ring has been used to this day for various types of anastomosis in the gastrointestinal tract, but it has not yet achieved widespread acceptance among surgeons. The purpose of this retrospective study is to compare surgical outcomes of sutureless with suture method of Roux-and-Y jejunojejunostomy in patients with gastric cancer. METHODS Two groups of patients were obtained based on anastomosis technique (sutureless group versus hand sewn group): perioperative outcomes were recorded for every patient. RESULTS The mean time spent to complete a sutureless anastomosis was 11 ± 4 min, whereas the time spent to perform hand sewn anastomosis was 23 ± 7 min. Estimated intraoperative blood loss was 178 ± 32 ml in the sutureless group and 182 ± 23 ml in the suture-method group with no significant differences. No complications were registered related to enteroanastomosis. Intraoperative mortality was none for both groups. CONCLUSIONS The Biofragmentable Anastomotic Ring offers a safe and time-saving method for the jejuno-jejunal anastomosis in gastric cancer surgery, and for this purpose the ring has been approved as a standard method in our clinic. Nevertheless currently there are few studies on upper gastrointestinal sutureless anastomoses and this could be the reason for the low uptake of this device.

Abstract
The main serious risks of anastomotic construction in the colon and rectum include dehiscence and stricture formation. There is a resurgence of interest in sutureless anastomoses formed by compression elements since the introduction of shape memory alloy (SMA) systems, which evoke minimal early inflammatory response whilst maintaining anastomotic integrity. Currently, the most commonly used SMA is the nickel-titanium (NiTi) alloy that is highly biocompatible, returning to its pre-deformed stable (austenite) shape under different mechanical and thermal loads for use in humans. Pre-clinical data for shape memory alloy systems in colorectal anastomoses are limited, but it appears to be safe in porcine and canine models with limited leakage and reduced stricture formation. There does not appear to be any difference in tissue biochemistry of inflammatory markers when compared with conventional stapled techniques, although the few studies available show a markedly reduced early inflammatory response at the anastomotic site with the NiTi device. The majority of the clinical data concerning compression anastomoses are derived from the biofragmentable anastomotic ring device. This device has fallen out of use because of reported leaks, instrumental failure and problems with device expulsion. A novel SMA device, the NiTi anastomotic ring, permits construction of a low rectal anastomosis construction during open or laparoscopic procedures. The preliminary data demonstrate a safety comparable to conventional staple technology. This device also provides the potential of benefit of reduced anastomotic inflammation, because the compression ring results in direct serosa-to-serosa (or alternatively serosa-to-muscularis propria) apposition without the persistence of residual foreign material. This type of construction could lead to a reduced incidence of early anastomotic leakage and/or the development of anastomotic stenosis. Randomized clinical trials employing a NiTi arm for elective, emergency and high-risk colorectal anastomoses are required to determine its indications and clinical profile as well as to assess whether such technology may selectively obviate the need for proximal diversion in low colorectal anastomoses.

Abstract
BACKGROUND Despite the fact that the concept of compression anastomosis has been investigated for nearly 2 centuries, it has not yet achieved widespread acceptance. The aim of the current report is to review the literature regarding compression anastomoses. DATA SOURCES A multi-database search was conducted using PubMed, Ovid, and the Cochrane Databases (all until June 2007), in addition to electronic links to related articles and references of selected articles. The following terms were used for the search in various combinations: anastomosis, anastomoses, sutureless, compression, nickel-titanium; Nitinol; CAC; CAR; AKA-2, Valtrac biofragmentable anastomotic ring, BAR. Language restrictions were not applied. CONCLUSIONS The various methods of compression anastomosis have been shown to be at least comparable to the standard techniques of suturing and stapling. The measurement of outcomes, including cost, safety, and efficacy of treatment, indicated that compression anastomosis can save time, is cost-effective, and offers an acceptable cost/benefit ratio compared to both stapled and sutured anastomoses. However, compression anastomosis did not gain worldwide popularity.

Abstract
The history and development for forming anastomoses using natural orifice translumenal endoscopic surgery (NOTES) techniques is described. Sutured gastrojejunostomy, enteroenteral anastomosis, and ileocolonic anastomoses using rigid and circular staplers passed through the rectum and vaginal wall using a transgastric supervising endoscope using a natural orifice translumenal endoscopic surgery hybrid approach. The staplers for this type of approach have to change. They need to be longer, more flexible, and able to change shape (eg, becoming smaller for introduction and then expanding in the peritoneal cavity). Different methods of introduction over guidewires or in combination with flexible gastroscopes are also needed. There is still a requirement for more ingenuity, persistence, and research if the goal of safer effective formation of anastomoses by less invasive means is to be realized.

Abstract
PURPOSE Uncertainty with the safety of the biofragmentable anastomosis ring makes surgeons hesitate in its widespread use in intestinal surgery. This study was designed to evaluate the validity of the biofragmentable anastomosis ring as a routine anastomotic device in enterocolic surgery. METHODS The study analyzed the nine-year experience of 632 biofragmentable anastomosis ring anastomoses performed in 617 patients: 525 (83 percent) as elective procedures and 107 (17 percent) as emergency. Three classic types of anastomosis, end-to-end (n=354), end-to-side (n=263), and side-to-side (n=15), were performed with a standard technique. RESULTS Anastomotic sites included ileocolic/ileorectal in 283 patients (45 percent), colorectal in 148 (23 percent), enteroenteric in 101 (16 percent), and colocolic in 100 patients (16 percent). Anastomotic leakage with clinical relevance was observed in five patients (0.8 percent): three elective cases, and two emergency (2 colorectal anastomoses and 1 ileorectal required diversions). Among 13 instances (2.1 percent) with postoperative intestinal obstruction, only 1 required relaparotomy for closed-loop obstruction. Seven patients (1.1 percent; 4 elective cases, and 3 emergency) died postoperatively; no deaths were directly related to the biofragmentable anastomosis ring technique. CONCLUSIONS Our data suggest that the anastomosis using the biofragmentable anastomosis ring is a uniform and highly reliable technique even in high-risk emergency surgery. Along with its clinical validities, clinical application of the biofragmentable anastomosis ring in different types of anastomoses in enterocolic surgery is expected to be expanded with a high level of technical safety.

Abstract
BACKGROUND The fear of anastomotic complications prevents the spread of the use of the biofragmentable anastomosis ring (BAR) in intestinal surgery. PATIENTS AND METHODS A total of 453 patients underwent intestinal resection and anastomosis with the BAR. RESULTS In all, 514 anastomoses have been carried out, 424 (83%) in elective settings, and 90 (18%) in emergency. Fifty-one patients had multiple anastomoses. Reoperation was performed in 4 patients (1%) who had a complete anastomotic leakage. In 13 patients (3%), anastomotic leakage was partial, and only 1 patient required reoperation. No postoperative intestinal obstruction occurred. Four patients (1%) developed late anastomotic strictures, which have been treated by endoscopic dilation. CONCLUSIONS The results of our experience and those of other large clinical series definitely confirm the effectiveness of the BAR method, which seems to be a standard, easy, rapid, and safe technique either in elective or emergency surgery.
