RESUMEN
BACKGROUND: Advanced megaesophagus predisposes to risks of malnutrition infections and cancer, in addition to having a significant impact on quality of life. There is currently no consensus in the literature regarding the best surgical option for advanced megaesophagus, although there is a predilection for esophagectomy, despite this surgery being associated with significant morbidity and mortality. Other surgical procedures, such as esophageal mucosectomy and Heller cardiomyotomy, have been proposed with good results. AIMS: To conduct a systematic review and meta-analysis of the literature on the surgical treatment of advanced megaesophagus. METHODS: Databases used included PubMed, Latin American and Caribbean Health Sciences Literature (Lilacs), Embase and Medical Literature Analysis and Retrieval System Online (MedLine), as well as reference research. Two reviewers selected the articles independently. RESULTS: A total of 14 articles were chosen, which included 1,862 patients. The studies were divided into two groups: laparoscopic cardiomyotomy with fundoplication (213 patients) and major surgeries (1,649 patients). The studies yielded mostly good or excellent results regarding late outcomes in both groups. However, there was significant morbidity associated with the major surgeries group. CONCLUSIONS: Laparoscopic Heller myotomy can be performed on patients with advanced megaesophagus, with lower rates of complications and mortality compared to major surgeries, with reservations regarding late outcomes results.

RESUMO RACIONAL: O megaesôfago avançado predispõe riscos clínicos de desnutrição, infecções e neoplasias, além de impacto significativo na qualidade de vida. Não há um consenso atual na literatura ante a melhor opção de seu tratamento cirúrgico, embora haja predileção pela esofagectomia, cirurgia de significativa morbimortalidade associada. Outras modalidades cirúrgicas têm sido propostas, com bons resultados, como a mucosectomia esofágica e a cardiomiotomia laparoscópica à Heller. OBJETIVOS: Realizar uma revisão sistemática com metanálise da literatura acerca do tratamento cirúrgico do megaesôfago avançado. MÉTODOS: As bases de dados utilizadas foram PubMed, Lilacs, Embase e MedLine, além de pesquisas de referências relacionadas. Os artigos foram selecionados por dois revisores independentemente. RESULTADOS: Foram selecionados 14 artigos, que incluem 1.862 pacientes. Os estudos foram divididos em dois grupos: cardiomiotomia laparoscópica com fundoplicatura (213 pacientes) e cirurgias de grande porte (1.649 pacientes). Os estudos analisados evidenciam que ambos os grupos apresentaram resultados semelhantes quanto ao desfecho tardio, considerado majoritariamente bom ou excelente, no entanto, houve significativa morbimortalidade associada ao grupo de cirurgias maiores. CONCLUSÕES: A cardiomiotomia laparoscópica com fundoplicatura pode ser realizada no megaesôfago avançado, com taxas de complicações e mortalidade reduzidas frente às cirurgias de grande porte, porém, com ressalvas quanto ao desfecho tardio a longo prazo.
RESUMEN
BACKGROUND: Common variable immunodeficiency (CVID) is a rare disease that affects children and adults and is often difficult to diagnose. Despite being one of the most frequent causes of immunodeficiency, involving gastrointestinal (GI), respiratory, and hematological systems, the disease onset can have heterogeneous and intermittent symptoms, frequently leading to diagnostic delay. GI symptoms are common and can include diarrhea, but the asymptomatic periods lead to overlooking the recurrent pattern. The same can occur with respiratory infections, thus delaying CVID suspicion. The starting point for CVID diagnosis is the decreased gamma globulin levels in serum protein electrophoresis (SPE), also observed through direct immunoglobulin's dosage. CASE PRESENTATION: The patient is a 38 years-old man who had intermittent diarrhea and recurrent airway infections for 19 years, but the CVID diagnosis was achieved only after SPE was carried out. At that time, he was already malnourished, and developed other complications related to CVID in a short period. CONCLUSIONS: SPE is readily available and inexpensive, but is not part of the laboratory approach in diarrhea. According to the case presented herein, it can be useful for patients with recurrent infections or other clues of the disease.
