Doctors are testing a new way to operate on stomach cancer that might be better than the traditional method. Researchers looked at 19 different studies comparing two surgical approaches for cancer in the upper part of the stomach. The newer technique, called double tract reconstruction, appears to work just as well at fighting cancer but helps patients keep their weight and nutrition better after surgery. It also causes less acid reflux (that burning feeling in your throat). This research suggests the newer method could become the preferred choice for certain stomach cancer patients because it combines cancer control with better quality of life after surgery.

The Quick Take

  • What they studied: Whether a newer surgical technique for upper stomach cancer (double tract reconstruction) works as well as the traditional surgery (total gastrectomy with Roux-en-Y) in terms of cancer control, complications, nutrition, and reflux problems.
  • Who participated: This review analyzed 19 published studies comparing these two surgical methods. The studies included patients with cancer in the upper portion of the stomach who needed surgery between 2010 and 2025.
  • Key finding: The newer double tract reconstruction surgery appears to work just as well at controlling cancer as traditional surgery, but patients had better nutrition afterward and fewer reflux problems, with similar complication rates.
  • What it means for you: If you or a loved one needs surgery for upper stomach cancer, this research suggests asking your doctor about double tract reconstruction as an option. It may help you maintain better nutrition and have fewer side effects after surgery, though your doctor will determine if you’re a good candidate based on your specific situation.

The Research Details

This is a systematic review, which means researchers carefully searched medical databases for all published studies comparing two different surgical techniques for stomach cancer. They looked at studies published between 2010 and January 2025, finding 19 studies that met their criteria. The researchers extracted detailed information from each study about surgery time, blood loss, complications, weight changes after surgery, nutritional markers like iron and protein levels, and reflux problems. They followed strict guidelines (called PRISMA) to make sure their review was organized and reliable. By combining information from multiple studies, they could see patterns and draw conclusions about which surgical approach might be better overall.

A systematic review is valuable because it combines evidence from many studies rather than relying on just one. This gives us a more complete picture of how well each surgical technique works. Since stomach cancer surgery is a major decision with long-term consequences, having this comprehensive comparison helps doctors and patients make informed choices about which approach might be best for each person’s situation.

This review followed established scientific guidelines (PRISMA) for conducting systematic reviews, which increases its reliability. The researchers searched multiple major medical databases to find studies, reducing the chance they missed important research. However, the review combined studies that may have had different patient populations and surgical techniques, which could affect the conclusions. The quality of the final conclusions depends on the quality of the individual studies included.

What the Results Show

The double tract reconstruction surgery performed comparably to traditional total gastrectomy in terms of long-term cancer survival and control, even though surgeons removed fewer lymph nodes (the small glands they check for cancer spread). This is important because it suggests you don’t need to remove as much tissue to effectively treat the cancer. The surgery time and amount of blood lost during the operation were similar between both techniques, with some studies actually showing the newer method was slightly faster or had less bleeding. Major complications after surgery occurred at similar rates in both groups, meaning the newer technique wasn’t riskier in terms of serious problems after the operation.

The most notable advantage of double tract reconstruction was a significant reduction in reflux esophagitis—that painful acid reflux condition where stomach acid backs up into your throat. Patients who had this newer surgery experienced much less of this problem compared to another surgical option (esophagogastrostomy), and had equal or better reflux control compared to traditional surgery. Additionally, patients who received double tract reconstruction maintained their weight better after surgery and had better nutritional markers, including higher levels of hemoglobin (oxygen-carrying protein), albumin (important body protein), and vitamin B12. These nutritional benefits are important because good nutrition helps with healing and overall health after major surgery.

This research builds on growing interest in function-preserving surgeries for stomach cancer—operations that remove the cancer while trying to keep the body working as normally as possible. Previous research suggested that removing the entire stomach might not always be necessary for cancers in the upper portion. This systematic review provides strong evidence supporting that idea by showing the newer, less extensive surgery works just as well for cancer control while offering better quality-of-life benefits. The findings align with a broader trend in cancer surgery toward preserving organ function when it’s safe to do so.

This review combined studies that may have used slightly different surgical techniques and included different types of patients, which could affect how well the conclusions apply to everyone. The review didn’t include all possible studies (only those published in major databases), so some relevant research might have been missed. Additionally, the studies varied in how carefully they measured outcomes like reflux and nutrition, which could affect the reliability of those comparisons. The review also couldn’t determine the ideal patient selection criteria—meaning we don’t yet know exactly which patients would benefit most from the newer technique versus traditional surgery.

The Bottom Line

Based on this evidence, double tract reconstruction appears to be a reasonable option for selected patients with cancer in the upper stomach, offering comparable cancer control to traditional surgery with better nutritional outcomes and less reflux. However, this should only be considered for appropriate candidates as determined by your surgical team. The decision should be made in consultation with your oncologist and surgeon who understand your specific situation. Confidence level: Moderate—the evidence is fairly strong, but individual patient factors matter significantly.

This research is most relevant for patients diagnosed with cancer in the upper portion of the stomach who are candidates for surgery. It’s also important for surgeons and oncologists who treat stomach cancer. Family members and caregivers should understand these options to support informed decision-making. This research does NOT apply to people with stomach cancer in other locations or those who cannot have surgery. It also doesn’t apply to people without stomach cancer.

If you have this surgery, you might notice improvements in nutrition and reflux symptoms within the first few weeks to months after recovery. Weight stabilization typically improves over 3-6 months as you return to normal eating. Long-term benefits in terms of quality of life may continue to improve over the first year after surgery. Cancer recurrence risk is typically assessed over 5 years, though some cancers can recur later.

Want to Apply This Research?

  • If you’ve had this surgery, track your weekly weight and any reflux symptoms (heartburn, regurgitation) on a scale of 0-10. Also monitor your energy levels and ability to eat different foods. This data helps you and your doctor see if you’re recovering well nutritionally.
  • Work with a dietitian to gradually expand your diet after surgery, focusing on protein-rich foods to maintain muscle and support healing. Use the app to log meals and track which foods cause reflux, helping you identify your personal triggers. Set reminders to take vitamin B12 and other supplements as recommended by your doctor.
  • Create a long-term tracking system that monitors weight trends monthly, reflux frequency weekly, and nutritional markers (like energy levels and food tolerance) regularly. Share this data with your healthcare team at follow-up appointments to ensure you’re meeting nutritional goals and managing any side effects effectively.
