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.

Asthma, laryngitis and chronic cough are atypical symptoms of the gastroesophageal reflux disease. To analyze the efficacy of laparoscopic surgery in the remission of extra-esophageal symptoms in patients with gastroesophageal reflux, related to asthma. Were reviewed the medical records of 400 patients with gastroesophageal reflux disease submitted to laparoscopic Nissen fundoplication from 1994 to 2006, and identified 30 patients with extra-esophageal symptoms related to asthma. The variables considered were: gender, age, gastroesophageal symptoms (heartburn, acid reflux and dysphagia), time of reflux disease, treatment with proton pump inhibitor, use of specific medications, treatment and evolution, number of attacks and degree of esophagitis. Data were subjected to statistical analysis, comparing the pre- and post-surgical findings. The comparative analysis before surgery (T1) and six months after surgery (T2) showed a significant reduction on heartburn and reflux symptoms. Apart from that, there was a significant difference between the patients with daily crises of asthma (T1 versus T2, 45.83% to 16.67%, p=0.0002) and continuous crises (T1, 41.67% versus T2, 8.33%, p=0.0002). Laparoscopic Nissen fundoplication was effective in improving symptoms that are typical of reflux disease and clinical manifestations of asthma.

The transient dysphagia after fundoplication is common and most often disappears until six weeks postoperatively. Analyze a group of patients who presented late and persistent dysphagia postoperatively. Forty-one patients after Nissen fundoplication, 14 male and 27 female, mean age 48 year, were evaluated based on medical history, esophagogastroduodenoscopy, contrast radiographic examination and esophageal manometry. The results were compared with another 19 asymptomatic individuals. Contrast radiographic examination of the esophagus revealed in six cases delayed emptying, characterizing that four patients had achalasia and two diffuse spasm of the esophagus. Esophageal manometry showed that maximal expiratory pressure of the lower sphincter ranged from 10 to 38 mmHg and mean respiratory pressure from 14 to 47 mmHg, values similar to controls. Residual pressure ranged from 5 to 31 mmHg, and 17 patients had the same values as the control group. The residual pressure of the lower sphincter was higher and statistically significant in patients with dysphagia compared with those operated without dysphagia. Future studies individualizing and categorizing each motility disorder, employing other techniques of manometry, and the analysis of the residual pressure may contribute to understand of persistent dysphagia in the postoperative fundoplication.

Dysplasia and esophageal adenocarcinoma may arise in patients with Barrett`s esophagus after fundoplication esophageal pH monitoring showing no acid in esophagus. This suggests the need to develop methodology to evaluate the occurrence of ultra-distal reflux (1 cm above the LES). The objective of the study was to compare acid exposition in three different levels: 5 cm above the upper border of the LES, 1 cm above the LES and in the intrasphincteric region. Eleven patients with Barrett`s esophagus after Nissen fundoplication with no clinical, endoscopic and radiologic evidence of reflux were selected. Four-channel pH monitoring took place: channel A, 5 cm above the upper border of the LES; channel B, 1 cm above the LES; channel C, intrasphincteric; channel D, intragastric. The results of channels A, B and C were compared. There was significant increase in number of reflux episodes and a higher fraction of time with pH <4.0 in channel B compared to channel A. There was significant decrease in fraction of time with pH <4.0 in channel B compared to channel C. Two cases of esophageal adenocarcinoma were diagnosed in the studied patients. The region 1 cm above the upper border of the LES is more exposed to acid than the region 5 cm above the upper border of the LES, although this exposure occurred in reduced levels. The region 1 cm above the upper border of the LES is less exposed to acid than the intrasphincteric region.
