Colonoscopy is a widely used endoscopic procedure to investigate diseases of the colon and rectum. Colonoscopy procedure has difficulties for the patient and endoscopist.
To investigate whether the use of an abdominal corset can make the colonoscopy procedure easier and faster.
This is a prospective randomised controlled study. Patients over 18 years of age who underwent elective colonoscopy in our clinic were evaluated. Patients were divided into two groups according to the use of the corset. Variables were compared between the groups.
A total of 204 patients were included in the study. Corsets were used in 97 patients and not used in 107 patients. The need for manual compression was found to be decreased in the corset use group. There was no effect of corset use on cecal intubation time in the general population. It was found that cecal intubation time decreased with corset use in patients with body mass index - BMI<30 and male gender.
The need for manual compression can be reduced by the use of an abdominal corset during colonoscopy. The use of an abdominal corset may make the colonoscopy procedure faster and easier for the endoscopist and the patient.
Despite all the advances in medicine and the wide variety of dressings available, the treatment of burn wounds still represents an important medical challenge. The pinus cellulose membrane dressing is a biomaterial with characteristics similar to those of bacterial cellulose, but with lower cost.
To evaluate the efficacy of pinus nanocellulose membrane on healing of deep second degree burns in rats and compare with Membracel®.
Thirty male Wistar rats were submitted to deep second degree burn in dorse, with boiling water at 97o C for 20 s, generating a 314 mm² area wound. The animals were distributed in three dressing groups (n=10): group 1 - simple gauze; group 2 - bacterial cellulose membrane (Membracel®); and group 3 - pinus cellulose membrane. They were evaluated for 20 days to verify clinical condition, macro and microscopic appearance and wound contraction.
All of them remained clinically well with no differences in weight. Crusts were observed in group 1, and none in groups 2 and 3. Regarding to scar contraction, groups 2 and 3 were similar, better than group 1. Microscopic analysis showed predominance of advanced healing degree in groups 1 and 3, and initial in group 2. Mature collagen was predominant in all groups.
The pinus nanocellulose membrane is effective in the treatment of experimental second degree burn in rats and its effectiveness is similar to that of the bacterial nanocellular membrane.
