First laser resection of the tumor. Adjustment with the spreading laryngoscope. The tumor is then resected macroscopically on all sides with a safety margin of at least 0.5 cm in healthy tissue. Resection includes the middle of the tongue base, extends to the vallecula and transition to the lingual epiglottis. Tumor is thread-marked and sent for frozen section assessment together with a cranial margin sample. The frozen section shows both the tumor specimen and the cranial margin specimen in healthy tissue. Tumor size 1.5 cm, penetration depth 0.13 mm. Subsequent careful hemostasis. This is followed by PEG insertion: flexible esophagoscopy into the stomach. Here, after creating the diaphanoscopy, insertion of a 15r abdominal wall tube in a typical complication-free manner. Guidance on the abdominal wall, sterile dressing. On retraction, in addition to the hyperplastic, slightly erosive cobblestone pattern in the stomach, the clear Barrett's esophagus at the gastroesophageal junction can also be seen. Completion of the procedure without complications. Postoperatively, from approx. 5-6 days onwards, diet build-up, otherwise feeding via PEG tube, if necessary initiation of swallowing diagnostics and, if necessary, swallowing rehabilitation. It is essential to see an internist due to pronounced Barrett's changes at the gastro-oesophageal junction.
