Background: Magnetic compression anastomosis (MCA) offers a simple and reliable technique for inducing anastomoses at any point along the digestive tract. Evidence regarding whether the design of the MCA device influences the anastomosis effect is lacking.
Aim: To investigate any difference in the side-to-side colonic anastomosis effect achieved with cylindrical circular ring magnets.
Methods: We designed cylindrical and circular ring magnets suitable for side-to-side colonic anastomosis in rats. Thirty Sprague-Dawley rats were randomly divided into a cylindrical group, circular ring group, and cylindrical-circular ring group ( = 10/group). Side-to-side colonic anastomosis was completed by transanal insertion of the magnets without incision of the colon. Operation time, perioperative complications, and magnet discharge time were recorded. Rats were euthanized 4 weeks post-operatively, and anastomotic specimens were obtained. The burst pressure and anastomotic diameter were measured sequentially, and anastomosis formation was observed by naked eye. Histological results were observed by light microscopy.
Results: In all 30 rats, side-to-side colonic anastomosis was completed, for an operation success rate of 100%. No postoperative complications of bleeding and intestinal obstruction occurred, and the postoperative survival rate were 100%. The operation time, magnet discharge time, anastomotic bursting pressure, and anastomotic diameter did not differ significantly among the three designs ( > 0.05). Healing was similar across the groups, with gross specimens showing good anastomotic healing and good mucosal continuity observed on histological analysis.
Conclusion: This study found no significant difference in the establishment of rat side-to-side colonic anastomosis with the use of cylindrical circular ring magnets.

Volvulus of the splenic flexure is a rare cause of large bowel obstruction. We present the case of a male in his mid-20s who presented with a three-day history of colicky left-sided abdominal pain. A computed tomography scan revealed severely dilated large bowel loops with a closed-loop obstruction in the left upper quadrant, which was thought to originate from the transverse colon.

We recently read with interest the article by Chi published in the . In this article, the authors reported a novel technique for re-establishing luminal continuity in a completely occluded colorectal anastomosis involving two endoscopes, one for radial electrical incision and the other serving as a guide light. However, this technique can be applied only in selected cases.

Background: Patients with ultra-low rectal cancer who underwent sphincter-preserving surgery are at high risk of poor anal function. Sphincter preservation in ultra-low rectal cancer poses significant challenges, and there is limited research exploring the impact of colonic J-pouch reconstruction on anal function in such patients. Given these challenges, the objective of this study was to assess the impact of colonic J-pouch reconstruction on quality of life and bowel function in patients who underwent sphincter-preserving surgery for ultra-low rectal cancer.

Background: Laparoscopic right hemicolectomy (RHC) is the primary surgical approach for right-sided colon cancer. Different ileo-colonic anastomosis techniques may lead to varied postoperative outcomes. This study aims to compare intracorporeal versus extracorporeal side-to-side anastomosis post laparoscopic RHC for short-term outcomes in right-sided colon cancer patients.
