ABSTRACT
Large hiatal hernias, besides being more prevalent in the elderly, have a different clinical presentation: less reflux, more mechanical symptoms, and a greater possibility of acute, life-threatening complications such as gastric volvulus, ischemia, and visceral mediastinal perforation. Thus, surgical indications are distinct from gastroesophageal reflux disease-related sliding hiatal hernias. Heartburn tends to be less intense, while symptoms of chest pain, cough, discomfort, and tiredness are reported more frequently. Complaints of vomiting and dysphagia may suggest the presence of associated gastric volvulus. Signs of iron deficiency and anemia are found. Surgical indication is still controversial and was previously based on high mortality reported in emergency surgeries for gastric volvulus. Postoperative mortality is especially related to three factors: body mass index above 35, age over 70 years, and the presence of comorbidities. Minimally invasive elective surgery should be offered to symptomatic individuals with good or reasonable performance status, regardless of age group. In asymptomatic and oligosymptomatic patients, besides obviously identifying the patient's desire, a case-by-case analysis of surgical risk factors such as age, obesity, and comorbidities should be taken into consideration. Attention should also be paid to situations with greater technical difficulty and risks of acute migration due to increased abdominal pressure (abdominoplasty, manual labor, spastic diseases). Technical alternatives such as partial fundoplication and anterior gastropexy can be considered. We emphasize the importance of performing surgical procedures in cases of large hiatal hernias in high-volume centers, with experienced surgeons.

Large hiatal hernias (LHH) besides being more prevalent in the elderly, have different clinical presentation: fewer reflux, more mechanical symptoms and a greater possibility of acute, life-threatening complications such as gastric volvulus, ischemia and visceral mediastinal perforation. Thus, surgical indications are distinct from gastroesophageal reflux disease (GERD-related), sliding hiatal hernias. Heartburn tends to be less intense, while symptoms of chest pain, cough, discomfort, and tiredness are reported more frequently. Complaints of vomiting and dysphagia may suggest the presence of associated gastric volvulus. Signs of iron deficiency and anemia are found. Surgical indication is still controversial and was previously based on high mortality reported in emergency surgeries for gastric volvulus. Postoperative mortality is especially related to three factors: body mass index (BMI above 35), age over 70 years and presence of comorbidity. Minimally invasive elective surgery should be offered to symptomatic individuals with good or reasonable performance status, regardless of age group. In asymptomatic and oligosymptomatic patients, besides obviously identifying the patient's desire, case-by-case analysis of surgical risk factors such as age, obesity and comorbidities, should be taken under consideration. One should also pay attention to situations with greater technical difficulty and risks of acute migration due to increased abdominal pressure (abdominoplasty, manual workers, spastic diseases). Technical alternatives such as partial fundoplication and anterior gastropexy can be considered. We emphasize the importance of performing surgical procedures in cases of LHH in high-volume centers, with experienced surgeons.
As grandes hérnias de hiato (HHG), além de serem mais prevalentes em idosos, têm apresentação clínica diferente: menos refluxo, mais sintomas mecânicos e maior possibilidade de complicações agudas e potencialmente fatais, como vólvulo gástrico, isquemia e perfuração mediastinal visceral. Assim, as indicações cirúrgicas são distintas das hérnias de hiato por deslizamento, relacionadas à doença do refluxo gastroesofágico (DRGE). A azia tende a ser menos intensa, enquanto os sintomas de dor no peito, tosse, desconforto e cansaço são relatados com maior frequência. Queixas de vômitos e disfagia podem sugerir a presença de volvo gástrico associado. São encontrados sinais de deficiência de ferro e anemia. A indicação cirúrgica ainda é controversa e foi anteriormente baseada na alta mortalidade relatada em cirurgias de emergência para volvo gástrico. A mortalidade pós-operatória está especialmente relacionada a três fatores: índice de massa corporal (IMC acima de 35), idade superior a 70 anos e presença de comorbidades. A cirurgia eletiva minimamente invasiva deve ser oferecida a indivíduos sintomáticos, com desempenho bom ou razoável, independentemente da faixa etária. Em pacientes assintomáticos e oligossintomáticos, além de obviamente identificar o desejo do paciente, deve-se levar em consideração a análise caso a caso dos fatores de risco cirúrgico, como idade, obesidade e comorbidades. Deve-se atentar também para situações de maior dificuldade técnica e riscos de migração aguda por aumento da pressão abdominal (abdominoplastia, trabalhos manuais, doenças espásticas). Alternativas técnicas como fundoplicatura parcial e gastropexia anterior podem ser consideradas. Ressaltamos a importância da realização de procedimentos cirúrgicos nos casos de GHH em centros de grande volume, com cirurgiões experientes.
