RESUMO
An arcuate line hernia is a generally asymptomatic, ascending protrusion of intraperitoneal structures over the linea arcuata. Arcuate line herniae are scarcely reported in the literature. Only a few publications were found. No clear descriptions of the techniques for repair have been published either. We aim to provide diagnostic images and illustrate our method to repair this hernia.
RESUMO
BACKGROUND: Digestive refeeding in acute pancreatitis represent a difficult issue. It requires the resolution of intestinal ileus and carries a risk of reactivation. AIM: To evaluate criteria that may guide in early refeeding avoiding unnecessary prolonged fasting. PATIENTS AND METHODS: Thirty patients with acute pancreatitis were evaluated in a prospective trial. The severity of the pancreatitis was evaluated according to APACHE II score and Balthazar CT scan alterations. The criteria proposed to start early refeeding were absence of nausea and vomiting, decreased abdominal pain, presence of bowel sounds and lowering of serum amylase levels. Balthazar CT scan classification, was used to decide between oral or enteral refeeding. RESULTS: Eighty percent of patients had alterations in pancreatic density, necrosis or pancreatic or peripancreatic liquid collections in the CT scan (corresponding to Balthazar stages C, D, or E). Ten patients fullfilled the criteria for enteral refeeding at 8.1 +/- 3.5 days (range 3 to 15 days), and 21 patients fulfilled criteria fo enteral refeeding at 8.7 +/- 4.5 (range 4-19). No patient had a reactivation of his pancreatitis. CONCLUSIONS: Digestive refeeding can be done safely by using the criteria proposed in this study. Pancreatic necrosis or peripancreatic fluid collections do not contraindicate refeeding. Oral feeding may be employed (as the first option) in selected patients, without increasing the risk of complication, regardless of CT scan alterations of the pancreas.
