“…In recent years, a number of natural and synthetic biomaterials have been developed to design scaffolds . Because of their excellent biocompatibility and biodegradability, natural biomaterials, such as collagen, silk fibroin (SF), and chitosan, have drawn much attention in the fields of tissue engineering and other biomedical applications …”

In this study, a porous silk fibroin (SF) scaffold was modified with soluble eggshell membrane protein (SEP) with the aim of improving the cell affinity properties of the scaffold for tissue regeneration. The pore size and porosity of the prepared scaffold were in the ranges 200-300 lm and 85-90%, respectively. The existence of SEP on the scaffold surface and the structural and thermal stability were confirmed by energy-dispersive X-ray spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, differential scanning calorimetry, and thermogravimetric analysis. The cell culture study indicated a significant improvement in the cell adhesion and proliferation of mesenchymal stem cells (MSCs) on the SF scaffold modified with SEP. The cytocompatibility of the SEP-conjugated SF scaffold was confirmed by a 3-(4,5-dimethyltriazol-2-y1)-2,5-diphenyl tetrazolium assay. Thus, this study demonstrated that the biomimic properties of the scaffold could be enhanced by surface modification with SEP. V C 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40138.

“…However, in our case and the cases of Fondran et al [ 11 ], because no remnant staple was found at the polyps, secondary ulceration and foreign body reaction of suture materials at the staple line was probably the cause of the inflammatory polyp. Therefore, chronic intramural stimulation during defecation may be a second possible cause for the formation of the rectal inflammatory granulation polyp, as in cases of silk sutures and vegetable seeds in colonic polyps [ 12 13 ]. However, Fondran et al [ 11 ] reported that in 2 of 9 patients, a polyp formed without suture reinforcement.…”

Persistent Bleeding Following a Stapled Hemorrhoidopexy

et al. 2016

A stapled hemorrhoidopexy (SH) is widely used for treatment of patients with grades III and IV hemorrhoids. The SH is easy to perform, is associated with less pain and allows early return to normal activities. However, complications, whether severe or not, have been reported. Here, we present the case of a female patient with persistent bleeding after a SH. The bleeding was caused by the formation of granulation tissue at the stapler line, diagnosed with sigmoidoscopy, and successfully treated via transanal excision (TAE) under spinal anesthesia. The biopsy showed inflammatory granulation tissue. After the TAE, her symptom was completely gone.

“…Although the mechanism underlying the migration of K-wires is unclear, prolonged mechanical factors, including muscular activity and regional reabsorption of bone, may have forced the Kwire to migrate from the pelvic bone to the pelvic cavity and protrude into the sigmoid colon in our case. In addition, chronic intramural stimulation of the migrated K-wire may have caused the development of the colonic inflammatory granulation polyp, as in cases of silk sutures and vegetable seeds in colonic polyps (9,10). Several recommendations have been made to prevent this potential complication (2).…”

An Inflammatory Polyp in the Colon Caused by the Migration of a Kirschner Wire Following Fixation of a Pelvic Fracture

et al. 2014

View full text Add to dashboard Cite

The migration of Kirschner wires (K-wires) is a rare complication. We herein present a case of an inflammatory polyp in the colon caused by the migration of a K-wire following fixation of a pelvic fracture. Surgery was carried out to remove the K-wire through an incision at the level of the left iliac bone. Simultaneous endoscopic clipping of the colonic wound was also performed. The patient's postoperative course was uneventful. Although very rare, migration of devices should be considered in patients with a previous history of orthopedic surgery.
