Study on functional cardiorespiratory changes after laparoscopic Nissen fundoplication

PURPOSE: To analyze the behavior of cardiopulmonary function in postoperative of laparoscopic Nissen fundoplication.METHODS: Thirty-two patients, 13 males (41%) and 19 females (59%), were evaluated. Their age ranged from 25 to 67 years, with a mean of 44.4 +/- 10.9. Pulmonary volumes, respiratory pressures and exercise tests were performed in the preoperative period (PRE) and in the first (PO1), second (PO2), fifth (PO5) and thirtieth (PO30) postoperative periods.RESULTS: Thirty-two patients were evaluated, of whom 59% were females. Mean age was 44.4 +/- 10.9 years. Lung volumes had significant decrease at PO1 and PO2 and were similar to PRE values at PO5. Respiratory pressures were altered only at PO1. The distance covered in the 6-minute walk test had significant reduction until PO2, and climbing time in the stair-climbing test significantly increased at PO2.CONCLUSION: Patients submitted to LNF surgery have decreased cardiorespiratory function in the early postoperative period; however, they soon return to preoperative conditions.

Funduplicatura de Nissen laparoscópico en el tratamiento de la enfermedad por reflujo gastroesofágico. Hospital Vicente Corral Moscoso. Cuenca, 1997-2008

Introducción: Alrededor del 25 a 50% de sujetos con enfermedad por reflujo gastroesofágico tienen enfermedad persistente progresiva, en ellos, la intervención quirúrgica constituye la mejor opción y el único recurso capaz de restaurar la barrera gastroesofágica. La funduplicatura de Nissen de elección, se realiza por laparoscopía desde febrero de 1997 en nuestro hospital. Objetivo: describir aspectos demográficos y clínicos de pacientes sometidos a funduplicatura de Nissen laparoscópico en el hospital Vicente Corral Moscoso. Método: análisis descriptivo y retrospectivo de videos e historias clínicas en estadística y cirugía de las funduplicaturas de Nissen laparoscópico. Resultados: de febrero 1997 a julio 2008, se realizaron 58 funduplicaturas, en 36 hombres y 22 mujeres, con un promedio de 42 años. Síntomas predominantes; pirosis, regurgitación, dolor abdominal y disfagia. Diagnosticados por: endoscopía digestiva alta y serie esófagogastroduodenal en todos. Com - plicaciones posoperatorias inmediatas: íleo 9, disfagia 5, retención urinaria 4. Tiempo operatorio promedio: 181 minutos en 1997, 102 minutos en 2008. Estancia hospitalaria: 4 días. 49 pacientes recibieron alimentación en 24 horas. No hubo conversiones ni mortalidad. Conclusiones: la cirugía laparoscópica en el tratamiento de ERGE va en aumento y constituye un tratamiento eficaz a largo plazo. Pero los cirujanos debemos también examinar los éxitos, los errores, las complicaciones y limitaciones de estas aplicaciones a largo plazo y con más variables estudiadas.

Barrett's Esophagus and Associated Adenocarcinoma : studies on pathogenesis, clinical staging and cost-utility of cancer treatment

Esophageal and gastroesophageal junction (GEJ) adenocarcinoma is rapidly increasing disease with a pathophysiology connected to oxidative stress. Exact pre-treatment clinical staging is essential for optimal care of this lethal malignancy. The cost-effectiviness of treatment is increasingly important. We measured oxidative metabolism in the distal and proximal esophagus by myeloperoxidase activity (MPA), glutathione content (GSH), and superoxide dismutase (SOD) in 20 patients operated on with Nissen fundoplication and 9 controls during a 4-year follow-up. Further, we assessed the oxidative damage of DNA by 8-hydroxydeoxyguanosine (8-OHdG) in esophageal samples of subjects (13 Barrett s metaplasia, 6 Barrett s esophagus with high-grade dysplasia, 18 adenocarcinoma of the distal esophagus/GEJ, and 14 normal controls). We estimated the accuracy (42 patients) and preoperative prognostic value (55 patients) of PET compared with computed tomography (CT) and endoscopic ultrasound (EUS) in patients with adenocarcinoma of the esophagus/GEJ. Finally, we clarified the specialty-related costs and the utility of either radical (30 patients) or palliative (23 patients) treatment of esophageal/GEJ carcinoma by the 15 D health-related quality-of-life (HRQoL) questionnaire and the survival rate. The cost-utility of radical treatment of esophageal/GEJ carcinoma was investigated using a decision tree analysis model comparing radical, palliative, and hypothetical new treatment. We found elevated oxidative stress ( measured by MPA) and decreased antioxidant defense (measured by GSH) after antireflux surgery. This indicates that antireflux surgery is not a perfect solution for oxidative stress of the esophageal mucosa. Elevated oxidative stress in turn may partly explain why adenocarcinoma of the distal esophagus is found even after successful fundoplication. In GERD patients, proximal esophageal mucosal anti-oxidative defense seems to be defective before and even years after successful antireflux surgery. In addition, antireflux surgery apparently does not change the level of oxidative stress in the proximal esophagus, suggesting that defective mucosal anti-oxidative capacity plays a role in development of oxidative damage to the esophageal mucosa in GERD. In the malignant transformation of Barrett s esophagus an important component appears to be oxidative stress. DNA damage may be mediated by 8-OHdG, which we found to be increased in Barrett s epithelium and in high-grade dysplasia as well as in adenocarcinoma of the esophagus/GEJ compared with controls. The entire esophagus of Barrett s patients suffers from increased oxidative stress ( measured by 8-OhdG). PET is a useful tool in the staging and prognostication of adenocarcinoma of the esophagus/GEJ detecting organ metastases better than CT, although its accuracy in staging of paratumoral and distant lymph nodes is limited. Radical surgery for esophageal/GEJ carcinoma provides the greatest benefit in terms of survival, and its cost-utility appears to be the best of currently available treatments.

Natural course of pontocerebellar hypoplasia type 2A

INTRODUCTION Pontocerebellar hypoplasia Type 2 (PCH2) is a rare autosomal recessive condition, defined on MRI by a small cerebellum and ventral pons. Clinical features are severe developmental delay, microcephaly and dyskinesia.Ninety percent carry a p.A307S mutation in the TSEN54-gene. Our aim was to describe the natural course including neurological and developmental features and other aspects of care in a homogeneous group of PCH2 patients all carrying the p.A307S mutation. PATIENTS AND METHODS Patients were recruited via the German patients' organizations. Inclusion criteria were imaging findings of PCH2 and a p.A307S mutation. Data were collected using medical reports and patient questionnaires discussed in a standardized telephone interview. RESULTS Thirty-three patients were included. When considering survival until age 11 years, 53% of children had died Weight, length and head circumference, mostly in the normal range at birth, became abnormal, especially head circumference (-5.58 SD at age 5 yrs). Neurologic symptoms: Choreathetosis was present in 88% (62% with pyramidal signs), 12% had pure spasticity. Epileptic seizures were manifest in 82%, status epilepticus in 39%. Non-epileptic dystonic attacks occurred in 33%. General symptoms: feeding difficulties were recorded in 100%, sleep disorder in 96%, apneas in 67% and recurrent infections in 52%; gastroesophageal reflux disease was diagnosed in 73%, 67% got percutaneous endoscopic gastrostomy and 36% a Nissen-fundoplication. Neurodevelopmental data: All children made progress, but on a low level: such as fixing and following with the eyes was seen in 76%, attempting to grasp objects (76%), moderate head control (73%), social smile (70%), rolling from prone to supine (58%), and sitting without support (9%). Ten percent lost achieved abilities on follow-up. The presence of prenatal symptoms did not correlate with outcome. CONCLUSION Phenotype of this genetically homogeneous group of PCH2 children was severe with reduced survival, but compatible with some developmental progress. Our data support the hypothesis of an early onset degeneration which thereafter stabilizes.

Caso imagiológico

Introdução: A tosse constitui um dos principais motivos de consulta médica e, apesar de na maioria dos casos ser de etiologia vírica ou alérgica, por vezes surgem diagnósticos inesperados. Caso Clínico: Criança do sexo feminino, 19 meses, sem antecedentes relevantes. Recorreu ao Serviço de Urgência por tosse produtiva há 3 semanas e rinorreia serosa, sem febre. Noção materna de dificuldade respiratória e recusa alimentar parcial. À admissão, polipneica, com tiragem subcostal e gemido expiratório. Auscultatoriamente, murmúrio vesicular globalmente diminuído, tempo expiratório aumentado e sibilos dispersos. Analiticamente sem alterações. A radiografia torácica evidenciou volumosa imagem quística no hemitórax direito. A TC to- rácica documentou estômago intratorácico. Foi submetida a laparoscopia que constatou hérnia do hiato paraesofágica. Após Fundoplicatura de Nissen ficou assintomática. Discussão: A hérnia do hiato é rara em idade Pediátrica, tendo sido um achado inesperado no caso clínico descrito. Consideramos assim que, apesar da sua raridade, as anomalias anatómicas devem ser consideradas no diagnóstico diferencial da tosse persistente.

Laparoscopic Heller Myotomy and Fundoplication in Patients with Chagas' Disease Achalasia and Massively Dilated Esophagus

Laparoscopic Heller myotomy and fundoplication is considered today the treatment of choice for achalasia. The optimal treatment for end-stage achalasia with esophageal dilation is still controversial. This multicenter and retrospective study aims to evaluate the outcome of laparoscopic Heller myotomy in patients with a massively dilated esophagus. Eleven patients (mean age, 56 years; 6 men) with massively dilated esophagus (esophageal diameter greater than 10 cm) underwent a laparoscopic Heller myotomy and anterior fundoplication between 2000 and 2009 at three different institutions. Preoperative workup included upper endoscopy, esophagram, and esophageal manometry in all patients. Average follow-up was 31.5 months (range, 3 to 60 months). Two patients (18%) had severe dysphagia, four patients (36%) had mild and occasional dysphagia to solid food, and five patients (45%) were asymptomatic. All patients gained or kept body weight, except for the two patients with severe dysphagia. Of the two patients with severe dysphagia, one underwent esophageal dilatation and the other a laparoscopic esophagectomy. They are both doing well. Heller myotomy relieves dysphagia in the majority of patients even when the esophagus is massively dilated.

Population-based trend analysis of laparoscopic Nissen and Toupet fundoplications for gastroesophageal reflux disease

The Nissen and Toupet fundoplications are the most commonly used techniques for surgical treatment of gastroesophageal reflux disease. To date, no population-based trend analysis has been reported examining the choice of procedure and short-term outcomes. This study was designed to analyze trends in the use of Nissen versus Toupet fundoplications, and corresponding short-term outcomes during a 10-year period between 1995 and 2004.
