ABSTRACT
Background: Sepsis is one of the main causes in burn victim's mortality. The use of negative pressure wound therapy (NPWT) provides an ideal environment to accelerate wound healing. We compare the use of normal saline (NS), intermittent NPWT, continuous NPWT and silver sulfadiazine in wound healing process. Method: This study involved 6 Yorkshire pigs; each pig was induced with 20 burns on the flank area. Burns were divided into 4 treatment groups: NS gauze, intermittent NPWT, continuous NPWT, and silver sulfadiazine dressing. Burns were evaluated on day 1,3,7,14, and 21 for its morphology and bacterial colonization and on day 14 and 21 for the remaining burn surface area. Result: Wound that received NPWT therapy appeared better in both granulation and crust formation. Remaining burn surface area (mm2) on day 14 in NS group, intermittent NPWT, continuous NPWT, and silver sulfadiazine were 107.43 ± 83.43, 178.07 ± 74.83, 146.10 ± 69.1, 126.03 ± 83.22, respectively(p = 0.457); on day 21 in NS group, intermittent NPWT, continuous NPWT, and silver sulfadiazine were 13.16 ± 16.86, 59.49 ± 20.72, 54.79 ± 46.59, 48.95 ± 39.84, respectively(p=0.169). There were no significant differences in each treatment group bacterial colonization(p>0.05). There were no significant correlation between bacterial colonization and remaining burn surface area (p>0.05). Conclusion: While morphologically, the wound in NPWT treatment groups appeared better in granulation and crust formation, the remaining wound surface area and the number of bacterial colonization were not significantly difference compared to standard therapy (silver sulfadiazine and NS gauze). There were no significant correlation between the amount of bacterial colonization and remaining wound surface area on every treatment group.
ABSTRACT
Introduction: Hemorrhoids are a common coloproctology problem and among 10% of cases need surgical intervention. However, the established surgical interventions still have many complications. Case presentation: We reported three female patients, who presented with circular 3rd degree internal hemorrhoids. The surgical treatment was performed with pre-operative anal dilatation using a 33 mm dilator for 20 minutes, followed by triangle incision above the dentate line. The hemorrhoid excision was performed, and the wound was sutured with simple interrupted radial sutures using a multifilament absorbable 3-0 thread. There were neither complaints of pain, bleeding, anal incontinence, anal stenosis, wound dehiscence, nor recurrence at the first, second, and fourth weeks of follow-ups in all patients. Discussion: Post-operative bleeding, pain, and anal incontinence are common after an open hemorrhoidectomy, while suture breakage and anal stenosis were reported after the old technique of closed hemorrhoidectomy. Stapled hemorrhoidectomy had less complications but requires a relatively more expensive cost for the device itself. We performed a combination of preoperative anal dilatation, above dentate line triangle incision, and simple interrupted radial sutures to treat the patients with 3rd degree internal hemorrhoids, which resulted in no post-operative complications within the first month of follow-up. Conclusion: A combination of preoperative anal dilatation, above dentate line triangle incision, and radial suture technique is a simple and effective surgical option for treating a 3rd degree hemorrhoid.
