Is catheter rupture rare after totally implantable access port implantation via the right internal jugular vein? Report of a case

Catheter rupture after totally implantable access port (TIAP) implantation via the right internal jugular vein is thought to be very rare. We report a case of catheter rupture found 682 days after TIAP surgery in a 52-year-old woman with recurrent right breast cancer. It is possible that chronic stress at the flexure of the catheter induced by neck movements caused the catheter to rupture. Therefore, when inserting a TIAP via the right internal jugular vein, the site of venous puncture should be decided on carefully. Although a fracture of this type is rarely reported in the literature, the incidence of catheter injury of a TIAP inserted via the internal jugular vein at our institute is 1.8 %. This highlights the need to educate and caution medical staff and patients about preventing catheter fracture being caused by external factors.     

Number of aberrant crypt foci in the rectum is a useful surrogate marker of colorectal adenoma recurrence

Aim: Endoscopic screening and removal of colorectal adenomas can reduce the incidence of colorectal cancer. However, given the possibility of adenoma recurrence, surveillance colonoscopy is currently recommended after the initial screening and removal of colorectal adenomas. Aberrant crypt foci (ACF) have been shown to serve as a reliable surrogate marker of colorectal carcinogenesis. In this study, the relationship between the number of ACF at the initial endoscopic polypectomy and the likelihood of colorectal adenoma recurrence after polypectomy were investigated. Methods: High‐magnification chromoscopic colonoscopy was performed in 82 subjects who underwent endoscopic polypectomy to identify ACF in the lower rectum. Surveillance colonoscopy was then performed 3 years after the baseline polypectomy at Yokohama City University Hospital. Results: The number of ACF was greater in patients who showed adenoma recurrence (7.88 ± 6.35) than in those who did not (2.19 ± 2.95) (P < 0.001). Receiver–operating curve analysis showed that the number of ACF was a highly specific predictor of the risk of adenoma recurrence. Conclusions: This is the first study conducted to investigate the relationship between the number of ACF after endoscopic polypectomy and the likelihood of recurrence of colorectal adenomas. These results suggest that the number of ACF is a useful predictor of the likelihood of colorectal adenoma recurrence.     

Ulcerative colitis with hepatitis B virus infection treated successfully by granulocyte monocyte apheresis

Ulcerative colitis (UC) is a major type of idiopathic inflammatory bowel disease (IBD). Immunosuppressive therapies are used to treat IBD patients. Clinicians have strong concerns about using immunosuppressive therapies for IBD patients with hepatitis B virus (HBV) infection because aggressive immunosuppressive therapy can promote reactivation of HBV. For that reason, physicians hesitate to use steroids or other immunosuppressive drugs for IBD patients with HBV infection. Granulocyte monocyte apheresis (GMA) is a safe and effective therapy for UC patients. In Japan, a maximum of 11 sessions of GMA are allowed for moderate‐to‐severe, steroid‐resistant UC patients. However, the effects of GMA on HBV remain unclear. This case report describes a 39‐year‐old man with active UC complicated by HBV infection. Although his symptoms improved with steroid treatment while under entecavir therapy, clinical remission could not be maintained after the steroid dosage was decreased, so GMA was started. After GMA initiation, the frequency of diarrhea decreased and his symptoms improved, and the steroid dosage could be decreased. During the course of GMA, the patient did not experience deterioration in his hepatitis and the HBV DNA level gradually decreased, although GMA itself did not affect the HBV DNA level during each session of GMA. Results show that GMA is a safe and efficacious strategy against UC complicated by HBV without affecting hepatitis because GMA had no remarkable effect on HBV activity. J. Clin.
