Laparoscopic Proximal Gastrectomy as a Surgical Treatment for Upper Third Early Gastric Cancer / 대한소화기학회지

Recently, the incidence of upper third gastric cancer has increased, and with it the number of endoscopic submucosal dissection (ESD) procedures performed has been increasing. However, if ESD is not indicated or non-curable, surgical treatment may be necessary. In the case of lower third gastric cancer, it is possible to preserve the upper part of the stomach; however, in the case of upper third gastric cancer, total gastrectomy is still the standard treatment option, regardless of the stage. This is due to the complications associated with upper third gastric cancer, such as gastroesophageal reflux after proximal gastrectomy rather than oncologic problems. Recently, the introduction of the double tract reconstruction method after proximal gastrectomy has become one of the surgical treatment methods for upper third early gastric cancer. However, since there has not been a prospective comparative study evaluating its efficacy, the ongoing multicenter prospective randomized controlled trial (KLASS-05) comparing laparoscopic proximal gastrectomy with double tract reconstruction and laparoscopic total gastrectomy is expected to be important for determining the future of treatment of upper third early gastric cancer.

A Case of Total Pharyngo-Laryngo-Esophagectomy and Colon Interposition for Hypopharynx Cancer in Subtotal Gastrectomised Patient / 대한이비인후과학회지

The choice of reconstruction in hypopharynx cancer is dependent on oncologic needs of the situation. If the cervical or thoracic esophagus is involved in hypopharynx cancer, esophagectomy and gastric pull-up or jejunal free flap graft or colon interposition are indicated. Colon interposition for esophageal reconstruction in hypopharynx cancer is performed only in patients whose stomach cannot be used for reconstruction because of the postgastrectomised status or simultaneous gastric cancer. We have recently experienced a case of total pharyngo-laryngo-esophagectomy and colon interposition in a patient with hypopharynx cancer who had received subtotal gastrectomy due to stomach cancer in the past. We provided a review of the current literature regarding colon interposition for esophageal reconstruction in hypopharynx cancer.
