Franzmann MD Abstract Background. Severe swallowing dysfunction is the dominant long-term complication observed in patients treated for head and neck squamous cell carcinoma (HNSCC) with treatment protocols using intensive concurrent chemotherapy with radiation therapy (chemo/XRT). We identified a subset of these patients, who were seen with complete obstruction of the hypopharynx distal to the site of the primary cancer, and in whom we postulate that the obstruction was caused by separable mucosal adhesions rather than obliteration by a mature fibrous stricture. Methods. Seven patients were referred to the senior author with a diagnosis of complete hypopharyngeal obstruction between 1992 and 2001. The diagnosis was confirmed by barium swallow imaging and/or endoscopy before referral in all patients. Patients underwent recanalization by passing a Jesberg esophagoscope under general anesthesia, followed by serial dilations and intensive swallowing therapy. Patient charts were reviewed retrospectively after institutional review board approval. Results. All seven patients were successfully recanalized. No patient had a perforation or other significant complication related to the recanalization procedure or subsequent dilations. Five of the seven patients showed improvement in swallowing at some point after the initial procedure, but just two patients recovered sufficiently to have their gastrostomy tube removed permanently. Conclusions. We conclude that complete hypopharyngeal obstruction secondary to mucosal adhesions is one cause of gastrostomy tube dependence in patients who have been treated with chemo/XRT for HNSCC. It is a difficult problem to treat, but most patients can recover useful swallowing function without undergoing laryngectomy or major surgical reconstruction. The postulated pathophysiology has implications for prevention as well as treatment. © 2006 Wiley Periodicals, Inc. Head Neck, 2006 [source] Anterior abdominal wall defects and biliary obstructionJOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 3 2005L Teoh Abstract:, Three infants with anterior abdominal wall defects (gastroschisis and exomphalos) who presented with obstructive jaundice secondary to biliary obstruction, are described. All three infants had abnormal biliary systems, with mechanical distortion of the biliary tree. Biliary obstruction secondary to structural biliary anomalies should be considered in patients with abdominal wall defects and cholestasis, as prolonged unrelieved biliary obstruction may lead to biliary cirrhosis and portal hypertension. [source] Laryngeal foreign bodies in children: First stop before the right main bronchusJOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 6 2003PJ Robinson Abstract: Laryngeal foreign bodies may produce either complete or incomplete airways obstruction. In complete airways obstruction the presentation is with calamitous respiratory difficulty. However incomplete laryngeal obstruction may present with less severe symptoms, resulting in possible misdiagnosis and confusion with other causes of upper airway obstruction such as infectious croup. This report describes three cases of incomplete laryngeal obstruction secondary to inhaled foreign bodies. In each case, the diagnosis of an inhaled foreign body was initially missed, resulting in delay in diagnosis and in one case prolonged recovery. The importance of considering laryngeal foreign bodies, both in cases of suspected foreign body inhalation and clinical cases of incomplete laryngeal obstruction are discussed.

Son DVM Abstract Objective , To evaluate clinical characteristics and outcomes of cats undergoing surgical intervention in the course of treatment for severe acute pancreatitis. Design , Retrospective observational study from 2003 to 2007 with a median follow-up period of 2.2 years (range 11 d,5.4 y) postoperatively. Setting , Private referral veterinary center. Animals , Eight cats. Interventions , None. Measurements and Main Results , Quantitative data included preoperative physical and clinicopathologic values. Qualitative parameters included preoperative ultrasonographic interpretation, perioperative and intraoperative feeding tube placement, presence of free abdominal fluid, intraoperative closed suction abdominal drain placement, postoperative complications, microbiological culture, and histopathology. Common presenting clinical signs included lethargy, anorexia, and vomiting. Leukocytosis and hyponatremia were present in 5 of 8 cats. Hypokalemia, increased total bilirubin, and hyperglycemia were present in 6 of 8 cats. Elevated alanine aminotransferase and aspartate transferase were present in all cats. Surgery for extrahepatic biliary obstruction was performed in 6 cats, pancreatic abscess in 3 cats, and pancreatic necrosis in 1 cat. Six of the 8 cats survived. Five of the 6 cats that underwent surgery for extrahepatic biliary obstruction and 1 cat that underwent pancreatic necrosectomy survived. All 5 of the cats with extrahepatic biliary obstruction secondary to pancreatitis survived. The 2 nonsurvivors included a cat with a pancreatic abscess and a cat with severe pancreatitis and extrahepatic biliary obstruction secondary to a mass at the gastroduodenal junction. Postoperative complications included progression of diabetes mellitus, septic peritonitis, local gastrostomy tube stoma inflammation, local gastrostomy tube stoma infection, and mild dermal suture reaction. Conclusion , Cats with severe acute pancreatitis and concomitant extrahepatic biliary obstruction, pancreatic necrosis, or pancreatic abscesses may benefit from surgical intervention. Cats with extrahepatic biliary obstruction secondary to severe acute pancreatitis may have a good prognosis. [source] Chronic rejection with sclerosing peritonitis following pediatric intestinal transplantationPEDIATRIC TRANSPLANTATION, Issue 8 2007Esther Ramos Abstract: Intestinal transplantation is considered the usual treatment for patients with permanent intestinal failure when parenteral nutrition has failed. Chronic rejection is a complication difficult to diagnose because of the scarcity and lack of specificity in the symptoms and the characteristics of typical histological findings. We report the case of a four-yr-old patient who received an isolated intestinal transplant. After developing a chronic rejection he presented an intestinal obstruction secondary to a sclerosing peritonitis that required the surgical removal of the graft. [source] | ||||||||||
