    The latissimus dorsi flap (LDF) is a surgical procedure employed by surgeons to reconstruct several types of breast cancer surgical defects, including modified radical mastectomy, quadrantectomy, and lumpectomy. The LDF can be used as a standalone autogenous flap, in combination with immediate implant-based reconstruction, in combination with tissue expanders for a phased reconstruction, or in either scenario, either immediately or at a later time. The LDF (Latissimus Dorsi Flap) is a reliable choice for soft tissue coverage during breast reconstruction, providing both form and function while minimizing potential complications in the short and long term. In cases of limited tissue availability, the LDF can assist by supplying additional tissue volume for autologous reconstruction. Additionally, it can function as a reliable vascular pedicle for implant-based healing in cases when the tissue has been exposed to radiation.

    Giant Zenkers diverticulum treated with diverticulectomy plus myotomy in tertiary hospital: case report
    (Medip Academy, 2024) Eduardo Michel Ramírez Robles; Samuel Rodrigo Gómez Arenas; Anahí Altamirano Santiago; Luis Fernando Pérez Solís; Erick Alfredo Pérez Ferrel; Roman Esteban Hernández González; Diana Laura Páramo Hernández; Sergio Federico Estrada Tijerina; Abigail Chávez Hernández; José Fernando Montiel Castañeda
    Zenker's diverticulum (ZD) is the most common esophageal diverticulum. Its prevalence is higher in older adults. It arises in the area called Killian's triangle, which is an area of weakness in the posterior wall of the upper esophagus, at the level of the upper esophageal sphincter (UES). This area is delimited by the fibers of the thyropharyngeal muscle laterally and by the fibers of the cricopharyngeal muscle (CPM) in the inferior. Due to its composition, it is classified as a false diverticulum because it contains mucosal and submucosal layers in its walls. The predominant symptom in 90% of patients is dysphagia, followed by regurgitation of undigested food content. We present the case of the successful diagnostic approach with tomography and esophageal-gastro-duodenal and therapeutic series with diverticulectomy plus myotomy with the use of a stapler to a patient with usual symptoms of ZD, but with an unusual size: a giant ZD.
