The changes in resting anal pressure after performing full-thickness rectal advancement flaps.
Background: Advancement flap is an accepted approach for treating complex fistula-in-ano. The purpose was to evaluate the changes in resting pressure along the anal canal after performing a full-thickness flap. Methods: Manometric review of patients who have undergone a full-thickness rectal advancement flap procedure for complex anal fistulas of cryptoglandular origin. Recurrence and continence were evaluated. Resting Anal Pressure was assessed along the anal canal by two measures: maximum resting pressure(MRP) and inferior resting pressure(IRP) at 0.5 cm from the anal verge. Results: 119 patients were evaluated. Overall recurrence rate was5.9%. Anal continence was maintained intact in 76.…
Effects of PEEP on Residual Vascularization in Oesophageal Substitution Gastroplasty by Surface Oximetry-Capnometry and Photoplethysmography
<i>Objective:</i> To evaluate the effects of positive end-expiratory pressure (PEEP) on residual vascularization in gastric tubes for oesophageal replacement. <i>Design:</i> Experimental open study. <i>Materials:</i> Eleven mongrel dogs. <i>Methods:</i> Intestinal parietal blood flow was evaluated by photoplethysmography (PPG) and measurement of surface oxygen (PsO<sub>2</sub>) and carbon dioxide (PsCO<sub>2</sub>) tensions under basal conditions. After Akiyama’s tubular gastroplasty, three levels of PEEP were administered. At each level, fluids were infused to counter the drop in cardiac output. PPG, surface gas tensio…
