Our Summary
This research paper is about the occurrence of gastroesophageal cancer (cancer that affects the stomach and esophagus) after gastric bypass surgeries. Gastric bypass is a type of weight-loss surgery that changes the way your stomach and small intestine handle the food you eat. The study analyzed all the reported cases of this type of cancer following two specific types of gastric bypass surgeries: Roux-en-Y gastric bypass (RYGB) and loop gastric bypass-one anastomosis gastric bypass/mini gastric bypass (LGB-OAGB/MGB).
The study found 50 cases of gastroesophageal cancer after these surgeries, with 61% of the cancers after RYGB occurring in the gastric tube (the part of the stomach that’s left after surgery), compared to 37.5% after LGB-OAGB/MGB. However, the study could not confirm an increased risk of cancer in the gastric tube after LGB-MGB/OAGB compared to RYGB.
The most common symptoms of the cancer were difficulty swallowing for cancers in the gastric tube, and abdominal pain for cancers in the excluded stomach (the part of the stomach that’s removed or bypassed during surgery). Most of the cancers in the gastric tube were diagnosed through a procedure called a gastroscopy, while most of the cancers in the excluded stomach were diagnosed by a CT scan.
The study suggests that gastroesophageal cancers after gastric bypass surgeries often occur in the excluded stomach and are not easily detected by traditional methods. Therefore, doctors and patients need to be aware of this risk and ensure regular follow-ups after surgery.

Doctor’s Tip
One helpful tip a doctor might tell a patient about gastric bypass is to make sure to attend all follow-up appointments and screenings as recommended. Regular monitoring and surveillance can help detect any potential issues, such as gastroesophageal cancer, early on and improve the chances of successful treatment. It’s important to communicate any new symptoms or concerns with your healthcare team promptly. Additionally, maintaining a healthy lifestyle, including a balanced diet and regular exercise, can also help reduce the risk of complications and promote overall well-being after gastric bypass surgery.
Suitable For
Patients who are typically recommended for gastric bypass surgeries are those who have a body mass index (BMI) of 40 or higher, or a BMI of 35 or higher with weight-related health problems such as type 2 diabetes, high blood pressure, or sleep apnea. Other factors that may make someone a candidate for gastric bypass include a history of failed weight loss attempts with diet and exercise, a commitment to making lifestyle changes post-surgery, and a willingness to participate in long-term follow-up care.
It is important for patients considering gastric bypass surgery to understand the potential risks and benefits, including the risk of developing gastroesophageal cancer post-surgery. Regular follow-up appointments with a healthcare provider are essential for monitoring any potential complications and addressing any concerns that may arise.
Timeline
Before gastric bypass surgery, patients typically undergo a series of evaluations to determine if they are suitable candidates for the procedure. This may include consultations with a bariatric surgeon, a nutritionist, a psychologist, and other healthcare providers. Patients also need to undergo various medical tests to assess their overall health and readiness for surgery.
After gastric bypass surgery, patients typically experience rapid weight loss in the first few months following the procedure. They may also experience changes in their eating habits, such as feeling full quickly or experiencing dumping syndrome (a group of symptoms that occur when food moves too quickly from the stomach to the small intestine). Patients are usually advised to follow a strict diet plan and exercise regimen to help them adjust to their new lifestyle and maintain their weight loss.
In the long term, patients who have undergone gastric bypass surgery may experience improvements in their overall health, such as reduced risk of obesity-related diseases like diabetes, hypertension, and sleep apnea. However, they may also face potential complications related to the surgery, such as nutritional deficiencies, gastrointestinal issues, and in rare cases, the development of gastroesophageal cancer, as shown in the research paper discussed above.
Overall, gastric bypass surgery can be a life-changing procedure for individuals struggling with severe obesity, but it is important for patients to be aware of the potential risks and complications associated with the surgery and to follow up regularly with their healthcare providers to monitor their health and well-being.
