[Argon plasma coagulation effective treatment of solitary rectal ulcer syndrome]. / Argonplasmakoagulation effektiv vid solitärt rektalt ulkussyndrom.

Solitary rectal ulcer syndrome (SRUS) is a rare disorder likely to be caused by a traumatic and ischemic mucosal injury related to latent or overt rectal prolapse. Mucosal damage can vary between erythema and up to intractable ulceration. The typical symptoms of SRUS may resemble those of inflammatory bowel disease (IBD)-related proctitis or rectal malignancy with mucus- and blood-mixed defecation with urgency and sometimes transient incontinence. The purpose of this paper is to raise awareness of this rare, quality-of-life impacting and difficult-to-treat disease and the not so well-known argon plasma coagulation (APC) treatment that can provide very good and long lasting symptom relief.

Non-activated autologous platelet-rich plasma for the prevention of inguinal wound-related complications after endovascular repair of abdominal aortic aneurysms.

The endovascular repair (EVAR) of abdominal aortic aneurysms (AAAs) usually involves the surgical exposure and catheterization of the femoral arteries. Several inguinal surgical wound-related complications have been reported postoperatively. The aim of this report was to evaluate the safety and efficacy of intraoperative application of autologous platelet-rich plasma (PRP) for the prevention of wound-related complications in AAA EVAR. The authors conducted a patient- and assessor-blinded controlled trial involving 100 subjects undergoing EVAR of an AAA. PRP was produced using an autologous platelet separator and was applied, without prior thrombin activation, in 50 patients eligible for inclusion. The results were compared with a control group of 50 patients who underwent AAA EVAR within the same time period. The primary outcome was the difference in postoperative hospital stay. Secondary outcomes included subjective assessment of wound healing and wound-related complications. Age, sex, and other comorbidities related to wound healing were not significantly different between cases and controls. One patient treated with PRP developed a unilateral wound infection with lymphorrhea, and two patients developed a bi-lateral superficial infection. Twelve patients within the control group developed a wound-related complication. The postoperative hospitalization was significantly lower in the PRP group. The overall surgical wound-related complications rate was also significantly lower in the PRP group. Application of non-thrombin-activated PRP seems to prevent major postoperative wound-related complications (p = .026) and shorten postoperative hospital stay duration after femoral artery exposure and catheterization for AAA EVAR (mean, 4.48 +/- 0.48 vs. 6.14 +/- 0.39 days).
