BACKGROUND Abscess formation is one of the complications after radical resection of rectal cancer;cases with delayed postoperative anastomotic abscess are rare.Here,we report a rare case of postoperative anastomotic abscess with a submucosal neoplasm appearing after rectal surgery.Ultimately,the patient was diagnosed and treated by endoscopic fenestration.In addition,we review the literature on the appearance of an abscess as a complication after rectal cancer surgery.CASE SUMMARY A 57-year-old man with a history of rectal malignancy resection complained of a smooth protuberance near the anastomotic stoma.Endoscopic ultrasonography revealed a hypoechoic structure originating from the muscularis propria,and a submucosal tumor was suspected.The patient was subsequently referred to our hospital and underwent pelvic contrast-enhanced computed tomography,which revealed no thickening or strengthening of the anastomotic wall.In order to clarify the origin of the lesion and obtain the pathology,endoscopic fenestration was performed.After endoscopic procedure,a definitive diagnosis of delayed anastomotic submucosal abscess was established.The patient achieved good recovery and prognosis after the complete clearance of abscess.CONCLUSION Endoscopic fenestration may be safe and effective for the diagnosis/treatment of delayed intestinal smooth protuberance after rectal cancer surgery. 展开更多

AIM: To evaluate a new technique of temporary ileal anastomotic stoma, following small bowel resection, in patients where the anastomosis is anticipated to have borderline margins with dubious viability. METHODS: Five patients underwent enterectomy and partially anastomosed end-loop ileostomy at the University Hospital of Larissa between 2000 and 2006. Enterectomy was performed because of conditions such as mesenteric vascular occlusive disease, radiation entritis and small bowel injury. RESULTS: Postoperatively, none of the patients developed any stoma-related or anastomotic complications. There were no major complications. All patients were discharged between the 8th and 15th day after the procedure, and the stoma was closed 3 wk to 4 wk later. CONCLUSION: We believe that our proposed modification of end-loop ileostomy is a simple, quick and safe technique with minimal stoma-related morbidity, and with simple and safe reversion. This technique can be considered as a useful option in the treatment of ischemic or radiation-induced enteritis, and in the management of severe intestinal trauma. 展开更多

Staplers have been widely used in the clinical treatment of gastrointestinal reconstruction.However,the current titanium(Ti)staple will remain in the human body permanently,resulting in some adverse effects.In this study,we developed a type of biodegradable staple for colonic anastomosis using 0.3 mm diameter magnesium(Mg)alloy wires.The wire surface was modified by micro-arc oxidation treatment(MAO)and then coated with poly-L-lactic acid(PLLA)to achieve a moderate degradation rate matching the tissue healing process.The results of tensile tests on isolated porcine colon tissue anastomosed by Mg and Ti staples showed that the anastomotic property of Mg staples was almost equal to that of Ti staples.The in vitro degradation tests indicated the dual-layer coating effectively enhanced the corrosion resistance and maintained the tensile force of the coated staple stable after 14-day immersion in the simulated colonic fluid(SCF).Furthermore,24 beagle dogs were employed to conduct a comparison experiment using Mg-based and clinical Ti staples for 90-day implantation by ent-to-side anastomosis of the colon.The integrated structure of Mg-based staples was observed after 7 days and completely degraded after 90 days.All animals did not have anastomotic leakage and stenosis,and 12 dogs with Mg-based staples fully recovered after 90 days without differences in visceral ion levels and other side effects.The favorable performance makes this Mg-based anastomotic staple an ideal candidate for colon reconstruction. 展开更多
