Summary
Laparoscopic proximal gastrectomy with double tract reconstruction offers better outcomes for early gastric cancer than total gastrectomy. Further trials are needed to confirm its benefits and establish it as a standard procedure.
Area of Science:
- Surgical Oncology
- Minimally Invasive Surgery
- Gastrointestinal Surgery
Background:
- Laparoscopic proximal gastrectomy (LPG) is a minimally-invasive, function-preserving option for proximal early gastric cancer (EGC).
- Concerns regarding oncological safety, functional benefits, and anastomosis complications have limited LPG adoption.
- Existing studies suggest LPG offers comparable oncological safety and better functional outcomes than total gastrectomy (LTG, OTG).
Purpose of the Study:
- To evaluate the efficacy and safety of laparoscopic proximal gastrectomy (LPG) with double tract reconstruction (DTR) for proximal early gastric cancer (EGC).
- To compare LPG with DTR against laparoscopic total gastrectomy (LTG) in terms of oncological safety, functional benefits, and complications.
- To provide evidence to guide surgical approach selection for proximal EGC.
Main Methods:
- A randomized clinical trial (Korean Laparoscopic Gastrointestinal Surgery Study-05, NCT01433861) comparing LPG with DTR to LTG.
- Assessment of oncological safety, functional outcomes (body weight, anemia), and anastomosis-related late complications.
- Analysis of surgical approach and reconstruction strategy for proximal EGC.
Main Results:
- LPG with DTR demonstrated superior body weight maintenance and anemia prevention compared to LTG in previous findings.
- While OPG with modified esophagojejunostomy showed comparable complication rates to OTG, no standard LPG reconstruction method is established.
- Recent studies indicate LPG and OPG have similar oncological safety and improved functional benefits over OTG and LTG.
Conclusions:
- Laparoscopic proximal gastrectomy with double tract reconstruction (LPG-DTR) shows promise for proximal early gastric cancer (EGC), particularly in preserving body weight and preventing anemia.
- Further randomized clinical trials are necessary to establish definitive evidence supporting LPG-DTR over laparoscopic total gastrectomy (LTG).
- The findings are expected to guide surgeons in selecting optimal surgical approaches and reconstruction strategies for proximal EGC.
