“…There were no experiences with end-to-end anastomosis and the performed anastomoses were only used as bypasses and not as the main route for intestinal transport. So far, this model is advised only for experiments in laboratory animals as well as for the treatment of animals [13]. There are experiences in military surgery with ballistic injuries and assessment of the use of disposable skin staplers in bowel anastomoses.…”

In contrast to adult surgery, the neonatal small intestine confronts the surgeon, depending on the age of the patient, with variable diameters of the intestine. Therefore, anastomoses are usually performed by hand with interrupted sutures. In the presented study, a new technique is demonstrated. An anastomosis in the distal ileum of Sprague Dawley rats was performed with a single clamp applicator (Anastoclip). Small bowel anastomoses were performed in 32 rats. The clipped bowel anastomosis was evaluated concerning stenosis, leakage, and adhesions in comparison to the sutured anastomosis. Tension test and X-ray examination were performed to measure the stability. The rats were sacrificed at day 3 or 14 after laparotomy. The clipped anastomosis is feasible, and faster to perform than the conventional hand-sutured anastomosis (Operation time: control group: 18.5 min versus clipped group 4 min; p > 0.05). Furthermore, there were differences in the mechanical stability, with higher tension forces needed for rupturing the clipped anastomosis. There were fewer stenoses (16.5 mm stenotic diameter in the control group versus 20.6 mm in the clipped group) and fewer adhesions in the group of the clipped anastomosis. Histological examinations were performed and did not show significant differences between the two groups. In the animal model presented, the clipped, intestinal, non-perforating anastomosis (CINPA) shows advantages compared to the common hand-sutured anastomosis.

Introduction: In gastric cancer surgery, gastrojejunostomy is one of the most important procedures. Anastomosis between different parts of the stomach and the intestine is a basic technical component in all gastrointestinal procedure. Backgrounds and aims: This study evaluated complications of gastrojejunostomy in gastric cancer surgery with two methods: singlelayer and double-layer anastomosis. Materials and methods: This study was carried out in the department of surgery in Mymensingh Medical College Hospital from January 1, 2009 to December 31, 2012. 100 patients with carcinoma stomach who needed gastrojejunostomy were included in this study. These patients with average age of 43.22 years were divided in two groups (50 in each group); single-layer and double-layer anastomosis. In single-layer anastomosis gastrojejunostomy was performed in interrupted method with absorbable suture (2/0 vicryl). Double-layer anastomosis was carried out with continuous suture (2/0 silk, 2/0 catgut). Possible post-operative complications like anastomotic leakage, pelvic abscess, abdominal sepsis, anastomotic stenosis and wound infection were evaluated. Results: In the single-layer group, 4 patients (8%) developed anastomotic leakage, wound infection and only 2 patients (4%) developed abdominal sepsis, pelvic abscess and anastomotic bleeding. No patient developed anastomotic stricture. In double-layer group, 2 (4%) patients developed anastomotic leakage, only 1 (2%) patient had pelvic abscess, abdominal sepsis and anastomotic bleeding but wound infection in 2 (4%) patients. Conclusion: Gastrojejunostomy with single-layer hand-sewn suture technique is safe without serious complications in comparison to double-layer suture technique. More-over operation time is less and cost is less in single-layer method.
