Hepatic involvement attributable to olmesartan is far less well known: clinical trials reported mild aminotransferase elevations in fewer than 2% of participants, a rate comparable to placebo. Nevertheless, in recent years several cases of severe acute hepatitis with variable latency periods have been published. The simultaneous occurrence of both potentially serious adverse effects is exceptionally uncommon, with only two patients described in the literature to date. We report the case of a 66-year-old woman receiving long-term therapy with a fixed combination of olmesartan medoxomil, amlodipine, and hydrochlorothiazide. More than two years after treatment initiation she developed chronic diarrhea (4-6 bowel movements per day). Months later, during an exacerbation of the diarrhea that produced hydro-electrolyte disturbances requiring hospitalization, she experienced jaundice and profound liver function test abnormalities, prompting an exhaustive investigation of both clinical pictures.

To review recent advances in the diagnosis and management of achalasia, with emphasis on functional classification, the role of emerging technologies, and the most effective therapeutic strategies. A narrative review of the literature in English and Spanish was conducted, including scientific articles, clinical practice guidelines, and recent international consensus statements (AGA 2024, ESGE 2025). The Chicago Classification v4.0 has improved the diagnostic accuracy of esophageal motility disorders through high-resolution esophageal manometry (HRM), facilitating more precise therapeutic decision-making. The peroral endoscopic myotomy (POEM) has demonstrated high clinical efficacy, particularly in type III achalasia. The laparoscopic Heller myotomy remains a valid option, especially when combined with fundoplication, while pneumatic dilation should be reserved for selected cases. Emerging technologies such as the EndoFLIP (Endoluminal Functional Lumen Imaging Probe) allow for dynamic assessment of the LES during diagnostic and therapeutic procedures, optimizing surgical planning and treatment individualization, while reducing complications and improving clinical outcomes.
