“…For whole circumferential lesions longer than 5 cm, the Japanese guidelines recommended surgery, chemoradiotherapy or radiotherapy. 6,8 Another indication for surgery would be the recurrent neoplasm adjacent to or at the site of previous endoscopic treatment. In such cases, repeat endoscopic treatment would be technically demanding as the submucosal layers will have extensive scarring.…”

Squamous dysplasia precedes invasive squamous cell carcinoma of the esophagus, but there is limited evidence on its surgical management. The “field change effect” further complicates matters, causing multifocal or second primary neoplasms in the esophagus and upper aerodigestive tract. While endoscopic procedures are the primary treatment, surgical resection, either alone or in combination with endoscopy, must be considered given the extent of the disease and organ involvement. This chapter summarizes multifocal squamous dysplasia scenarios and highlights the role of esophagectomy or surgical resection.

“…Therefore, the standard treatment for this cancer is surgery or irradiation 2 ; however, these treatments have a disadvantage of over‐invasiveness. Currently, endoscopic submucosal dissection (ESD) is a standard treatment for SEC because of its minimal invasiveness and good effectiveness 3 . ESD for SEC in a diverticulum is challenging for endoscopists, and the indication of ESD should be determined with caution.…”

Superficial esophageal cancer (SEC) in a diverticulum is rare and has a high risk of perforation during endoscopic resection. Although endoscopic submucosal dissection (ESD) is a standard treatment option, it is challenging to perform. Here, we describe the case of a 79‐year‐old male patient with a history of ESD for SEC. Surveillance esophagogastroduodenoscopy identified a 20‐mm‐sized reddish depressed lesion in a diverticulum in the middle esophagus. The lesion was confirmed to be squamous cell carcinoma by biopsy. Magnification endoscopy with narrow‐band imaging showed intraepithelial papillary capillary loops of type B1 according to the magnified endoscopic classification of the Japan Esophageal Society. Endoscopic ultrasonography revealed the presence of the muscular layer of the esophagus wall in the diverticulum. Therefore, the lesion was diagnosed as SEC, confined to the epithelium or lamina propria mucosae, in a Rokitansky diverticulum. Based on these findings, ESD was considered technically feasible. Traction‐assisted ESD using clip with line was performed, and en bloc resection was achieved without adverse events. The resected specimen pathologically revealed a squamous cell carcinoma confined to the lamina propria mucosae without lymphovascular invasion, suggesting a curative resection. The patient recovered well, and no recurrence has been observed for 5 years after the ESD. Whether ESD is appropriate for the treatment of SEC in a diverticulum remains unclear. However, our case shows that it can be a treatment option in such cases due to its minimal invasiveness and good effectiveness.

“…Squamous cell carcinoma is the predominant type of esophageal cancer in Asia 2 . Endoscopic resection (is a curative treatment for esophageal cancers with negligible risk of metastasis, 3 while additional treatment after endoscopic resection is recommended for cancers with a substantial risk of metastasis based on a pathological assessment of resected specimens 4,5 …”

“…Esophagectomy and chemoradiotherapy are the leading options for adjuvant therapy for esophageal squamous cell carcinoma after endoscopic resection 4,5 . The extent of lymphadenectomy during esophagectomy and the radiation field in chemoradiotherapy are determined based on the subsite of the original esophageal squamous cell carcinoma, such as the cervical esophagus, upper thoracic esophagus, middle thoracic esophagus, or lower thoracic esophagus 5–8 .…”

ObjectivesIndividual treatment strategies for esophageal cancer have been investigated based on the anatomical subsite classification. Accurate subsite classification based on these anatomical landmarks is thus important. We investigated the suitability of the existing endoscopic classification and explored alternative landmarks for esophageal subsite classification.MethodsPatients who received endoscopic ultrasonography (and computed tomography scans for surveillance of esophageal cancer treatment or esophageal submucosal tumors were included. Distances between anatomical landmarks, including the inferior cricoid cartilage border, superior border of the sternum, and tracheal bifurcation, were measured using a combination of endoscopic ultrasonography, computed tomography, and other information.ResultsThe mean (standard deviation) distances from the superior incisor dentition to the pharynx–esophagus, cervical–upper thoracic esophagus, and upper–middle thoracic esophagus boundaries were 16.9 (1.7), 21.7 (1.9), and 29.0 (1.9) cm, respectively. However, variances in the differences between the mean and individual distances were large (2.8, 3.4, and 3.7, respectively), mainly because of differences in body height. However, variances in the differences between individual distances and novel endoscopic landmarks, including the lower end of the pyriform sinus and lower end of compression of the left main bronchus, were lower (1.7, 1.2, and 0.6, respectively).ConclusionsExisting indicators of esophageal subsite boundaries were not consistent with anatomical boundaries. Modification of the distance from the superior incisor dentition based on average distances from anatomical landmarks or the use of alternative endoscopic landmarks is recommended to provide more suitable anatomical boundaries.
