O esôfago curto e o refluxo distal são fatores de risco para o refluxo proximal? Short length of the esophagus and distal reflux are risk factors for proximal esophageal reflux?

RACIONAL: Não está claro se pacientes que apresentam refluxo gastroesofágico distal têm maior risco de apresentar também refluxo proximal. O senso comum sugere que um episódio de refluxo poderia chegar mais facilmente à faringe em pacientes que tivessem menor distância a percorrer entre o esfíncter inferior do esôfago e o superior. OBJETIVO: Investigar se o esôfago curto e a presença de refluxo esofágico distal são fatores de risco para refluxo proximal nos pacientes com sintomas respiratórios. MÉTODO: Cento e sete pacientes foram avaliados prospectivamente por meio de entrevista, esofagoscopia, manometria e pHmetria. Utilizaram-se o teste t de Student, o de correlação de Spearman, o do Qui-quadrado e odds-ratio. O nível de significância foi 0,05. RESULTADOS: Os sintomas que motivaram a investigação da doença do refluxo gastroesofágico foram: tosse 43 (40,2%); pigarro 25 (23,4%), globo faríngeo 23 (21,5%) e rouquidão 16 (14,9%). No estudo endoscópico 22 apresentaram esofagite e 14 hérnia de hiato. Na avaliação manométrica 11 (10,8)% apresentaram hipotonia do esfíncter inferior. A média do comprimento do esôfago foi 24,3 (± 1,9) cm, variando de 20 a 30 cm. Na avaliação pHmétrica 23 (21,5%) apresentaram refluxo distal patológico e 12 (11,2%) refluxo proximal. CONCLUSÕES: O comprimento do esôfago não esteve associado com a presença de refluxo proximal. Pacientes que apresentaram refluxo gatroesofágico distal, independente do comprimento do esôfago, tiveram risco aumentado de 4,6 vezes para apresentarem refluxo proximal.<br>BACKGROUND: It is not clear whether patients suffering from distal esophageal reflux also present high risk to proximal esophageal reflux. Common sense suggests that reflux would more easily reach the pharynx in patients who have a smaller distance between the lower esophageal sphincter and the upper one and, thus, short esophagus. AIM: To Investigate if short esophageal length and presence of esophageal distal reflux are risk factors for proximal reflux among patients presenting respiratory symptoms. METHODS: A hundred and seven patients were evaluated prospectively by interview, esophagoscopy, manometry and 24-hour esophageal pH monitoring. Student's t test (two-sided), Spearman's rank correlation, Chi-square and odds ratio were used in the statistical analysis. Significance level was set at 0.05. RESULTS: Respiratory symptoms that motivated the search for gastroesophageal reflux disease were cough 43 (40.2%); throat irritation 25 (23.4%), pharyngeal globe 23 (21.5%) and hoarseness 16 (14.9 %). By esophagoscopy, 22 (27.2%) presented some degree of esophagitis. A hiatal hernia was observed in 14 (17.5%) patients. According to manometry, 11 (10.8%) had lower esophageal sphincter hypotonia. The average esophageal body length was 24.3 (± 1.9) cm, ranging from 20 to 30 cm. The esophageal length was not associated with the presence of proximal esophageal reflux. As indicated by pH monitoring, 23 (21.5%) presented pathologic distal reflux and 12 (11.2%) had proximal reflux. CONCLUSION: The esophageal length was not associated with the presence of proximal esophageal reflux. Patients who had pathological distal esophageal reflux, independent of the esophageal length, were 4.6 times more likely to have proximal esophageal reflux

Fixation-free incisional hernia repair in the elderly: our experience with a tentacle-shaped implant

Background: Incisional hernia in aged patients represents a challenge even for experienced surgeons. Besides increased risk of complications due to comorbidities, mesh fixation and assuring a sufficient mesh overlap of the defect are the main issues in carrying out the repair. Aims: In order to assure broader coverage of the abdominal wall and a tension- and fixation-free repair, a specifically designed prosthesis was developed for the surgical treatment of incisional hernias. The results of a fixation-free incisional hernia repair carried out in elderly patients using a tentacle-shaped implant are reported herewith. Methods: A tentacle-shaped flat mesh with a large central body and integrated arms was used to repair incisional hernia in 23 elderly patients. The mesh was placed fixation-free and secured in place through the friction exerted by the tentacles. All tentacle straps were positioned with a special passer needle. Implant placement was preperitoneal in 18 patients and retromuscular sublay in five. Results: In a follow-up of 18 to 59 months (mean 36 months), four seromas occurred. Postoperative fast track helped avoid the typical complications affecting this patient subset. No infection, hematoma, chronic pain, mesh dislocation or recurrence have been reported to date. Discussion: The tentacle strap system allowed for reduced skin incision thus minimizing surgical trauma and ensuring easier and faster implant placement. Conclusion: The tentacle arms of the implant ensured mesh stability and broad defect overlap. Besides a very low complication rate, none of the typical postoperative complications of aged patients occurred
