We reviewed our experience of Roux-en-Y hepaticojejunostomy (RYHJ) and hepaticoduodenostomy (HD) performed for the surgical repair of choledochal cyst (CC), with special emphasis on postoperative complications related to the type of biliary reconstruction performed. Eighty-six patients underwent primary cyst excision for CC from 1986 to 2002 at our institution. Forty-six cases with concurrent intrahepatic bile duct dilatation (IHBD) were excluded because HD was not used for biliary reconstruction if IHBD was present. Thus, 28 cases had RYHJ, and 12 had HD. Differences between the RYHJ and HD groups with respect to type of CC, age at cyst excision, and length of follow-up were not statistically significant. However, the incidences of postoperative complications related to biliary reconstruction, such as endoscopy-proven bilious gastritis due to duodenogastric bile reflux [4/12 (33.3%) of the HD group], and adhesive bowel obstruction/cholangitis [2/28 (7.1%) of the RYHJ group] were significantly different (p<.05). Our experience suggests that HD is not ideal for biliary reconstruction in CC because of a high incidence (33.3%) of complications due to duodenogastric bile reflux. Currently, RYHJ is our exclusive technique of choice for biliary reconstruction during the surgical repair of CC.
Cathelicidins are a family of antibacterial peptides. Human cathelicidin LL-37 inhibits the binding of endotoxin lipopolysaccharide (LPS) to CD14-positive cells and could ameliorate sepsis. The aim of this study was to observe the effect of LL-37 on sepsis in neonatal rats. Intraperitoneal injection (IPI) of LPS was used to create sepsis in suckling rats. Group 1 rats were given LPS with LL-37, group 2 rats were given LL-37 2 h after LPS, and group 3 rats were given LPS without LL-37. Control group rats were given isovolemic normal saline by IPI. Rats given LL-37 IPI were divided into seven subgroups. Following IPI, an overall assessment score (OAS) and rectal temperature (RT) were assessed hourly. Serum C-reactive protein (CRP) was also assessed at death or at sacrifice 10 h after IPI. All rats in group 3 died. For rats receiving lower doses of LL-37 in groups 1 and 2, mortality was decreased. No deaths occurred among those receiving higher doses of LL-37 in group 1; however, mortality increased in group 2. In group 1, OAS and RT deteriorated initially for those receiving lower doses of LL-37, then improved. OAS and RT did not deteriorate throughout the study in rats given higher doses of LL-37. In group 2 rats given higher doses of LL-37, OAS and RT were not significantly different from rats in group 3. CRP was significantly decreased in group 1 compared with group 3, and decreased in group 2 for lower doses only. We conclude that LL-37 may prevent sepsis and be useful in lower doses for treating sepsis. However, LL-37 appears to have adverse effects when used at higher doses for treating sepsis.
Gastrointestinal stromal tumors (GIST) are c-KIT positive neoplasm that occur predominantly in adults. A 13-year-old boy who presented with massive gastrointestinal hemorrhage was subsequently diagnosed with GIST of the stomach. The tumor originated from the lesser curvature with a narrow base and no infiltration into surrounding organs. Two metastatic lesions in the liver were also found. Total excision of the gastric lesion was performed followed by adjuvant imatinib mesylate chemotherapy. He has had no signs of recurrence during 8 months of follow-up. GIST in children are rare and their behavior is notoriously difficult to predict. We report our experience and review the literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
