Use of photoplethysmography to determine gastrointestinal perfusion pressure: an experimental canine model.
<i>Objectives:</i> To develop an experimental model to assess the parietal perfusion pressure (PPP) of the digestive tract using photoplethysmography. <i>Materials and Methods:</i> Twenty-two mongrel dogs were used. Progressive external compression was applied to the intestinal wall and the PPP was assessed with photoplethysmography. The study group was divided into two groups. In group 1 PPP was measured at the levels of the stomach, duodenum, jejunum and transverse colon. In group 2 PPP was measured after temporary occlusion of the truncal and marginal circulation of the jejunum to provide further variables. <i>Results:</i> The PPP decreased significant…
Fistulectomy and sphincteric reconstruction for complex cryptoglandular fistulas
Objective Complex anal fistulas (CFs) are difficult to treat. Endoanal advancement flap (EAF) is one of the standard treatment options for such clinical conditions. Immediate sphincter repair after fistulectomy (ISR) is not commonly performed because of the fear of causing postoperative incontinence. The objective of this study was to compare the results of both techniques. Method We retrospectively analysed a prospectively entered database composed of 146 patients (112 M; 34 F), undergoing operations for CF of cryptoglandular origin. The patients were divided in two groups: Group A: (EAF); n = 71 patients; Group B: (ISR); n = 75 patients. Results Forty-two fistulas (28.7%) were recurren…
