Comparative evaluation of different types of gastric conduits used for single-stage reconstruction during oesophageal cancer esophagectomy. Review

Abstract

In the treatment of local and local‑regional oesophageal cancer, esophagectomy takes centre stage. It is a complex procedure with a high rate of postoperative complications. There are different methods for oesophageal reconstruction, including colon interposition, supercharged jejunal interposition, and gastric pull‑up. Each has both advantages and disadvantages. However, a gastric graft is the preferred option due to the less traumatic nature of the operation. Currently, there are different methods for forming a gastric graft. Gastric conduits are classified based on their shape and can be categorised as whole‑stomach, sub‑total stomach, or gastric tube. Previous research on the functional characteristics of gastric conduits revealed that the most effective solution is a typical gastric tube. Due to its width (3—6 cm), the gastric tube limits its impact on lung movement within the pleural cavity, hence decreasing the incidence of postoperative respiratory complications (e.g., pneumonia). Pulmonary complications and anastomotic leaks are the main contributing causes of postoperative morbidity and mortality after esophagectomy. Other complications include technical and functional issues, as well as delayed problems such as anastomotic strictures and disease recurrence. However, the rate of complications remains between 20 and 80%, prompting oncologic surgeons to develop new methods for gastric conduit formation. Over the past 5 years, innovative methods using a special‑shaped gastric tube have been suggested. They appear to decrease the incidence of postoperative complications and enhance nutritional outcomes. This study aimed to evaluate the advantages of using special‑shaped gastric tubes in clinical practice as opposed to whole‑stomach and typical gastric tubes.
