ObjectiveTo explore guiding significance of intraoperative frozen section for judging incisal edge range of esophageal carcinoma.MethodsA retrospective descriptive research design was used to collect the clinical and pathological data of 205 patients with esophageal cancer who were treated in Huaihe Hospital of Henan University from March 2012 to July 2015. Among them, 46 patients' esophageal margins were made into intraoperative frozen sections.ResultsIn the 205 cases, nine cases were diagnoses with upper incisal edge cancerization, accounting for 4.39%, and five cases were diagnosed with lower incisal edge cancerization, accounting for 2.4%. There were 14 cases in total, accounting for 6.83%. four cases showed positive residual end of intraoperative frozen section.ConclusionThe cancerous focus residue of incisal edge in esophageal carcinoma is not uncommon. Intraoperative frozen section is helpful to judge the proper excision length of esophageal carcinoma.Copyright: © Pakistan Journal of Medical Sciences.
