A 67-year-old Brazilian woman with Chagas disease developed severe swallowing problems and esophageal enlargement 15 years after her initial infection. According to Gram Research analysis, laparoscopic surgery to cut the tight muscle at the bottom of her esophagus restored her ability to eat normally within 5 weeks, with complete symptom resolution by 5 months—demonstrating that surgical intervention can effectively treat advanced Chagas-related digestive complications.
A 67-year-old woman from Brazil developed severe difficulty swallowing years after being treated for Chagas disease, a parasitic infection. Her esophagus (food pipe) became enlarged and damaged, making it hard to eat. After diagnostic delays, she underwent a minimally invasive surgical procedure that successfully restored her ability to eat normally. According to Gram Research analysis, this case highlights how Chagas disease can cause long-term digestive problems even after treatment, and shows that surgery can help patients regain their quality of life.
Key Statistics
A 2026 case report documented a 67-year-old woman with Chagas disease who had a 7-centimeter esophageal dilation and could only consume liquids, but regained normal eating ability within 5 weeks after laparoscopic cardiomyotomy surgery.
Research shows laparoscopic cardiomyotomy achieves approximately 90% success in treating Chagas-related megaesophagus in early-to-moderate stages (Rezende classification groups I-III), as demonstrated by this patient’s complete symptom resolution.
A patient with Chagas disease-related swallowing problems experienced a 3-year diagnostic delay from symptom onset in 2019 to imaging confirmation in 2022, highlighting healthcare access barriers in endemic regions.
The Quick Take
- What they studied: How a surgical procedure called cardiomyotomy (cutting specific muscles in the food pipe) could help a patient with severe swallowing problems caused by old Chagas disease damage.
- Who participated: One 67-year-old woman from northeastern Brazil who had been treated for Chagas disease 15 years earlier but developed worsening throat and swallowing problems starting in 2019.
- Key finding: After surgery in 2023, the patient went from being able to eat only liquids to eating a completely normal diet within 5 weeks, with no symptoms by early 2024.
- What it means for you: If you have Chagas disease or live in an area where it’s common, early screening and treatment matter. If swallowing problems develop, surgery may help restore normal eating—but this is one patient’s experience, not a guarantee for everyone.
The Research Details
This is a case report, which means doctors documented the medical journey of one specific patient in detail. The patient was a 67-year-old woman from Rio Grande do Norte in northeastern Brazil who had been diagnosed with Chagas disease in 2004 and received treatment at that time. She developed progressive difficulty swallowing solid foods and nighttime regurgitation (food coming back up) starting in 2019.
Doctors used several tests to understand her problem: chest X-rays, heart electrical tests (ECG), heart ultrasounds, and imaging studies with barium (a special dye that shows up on X-rays). These tests were delayed until 2022 due to COVID-19 restrictions. The imaging revealed her esophagus was severely enlarged (7 centimeters wide) with narrowing at the bottom, and food was getting stuck inside. In September 2023, she underwent a minimally invasive surgical procedure called laparoscopic Heller-Pinotti cardiomyotomy, where surgeons made small cuts and carefully divided the tight muscle at the bottom of her esophagus.
The doctors followed her recovery closely, tracking her ability to eat, weight changes, and symptom resolution over the following months.
Case reports are valuable because they document real-world patient experiences and show what can happen when certain treatments are used. This case is important because it demonstrates that surgery can help people with Chagas disease-related swallowing problems, even years after the initial infection. It also highlights real-world challenges in healthcare systems, including diagnostic delays and limited resources.
This is a single-patient case report, which is the lowest level of scientific evidence. It shows what happened to one person but cannot prove the treatment works for everyone. However, the doctors provided detailed medical records, imaging results, and follow-up information, which makes this case well-documented. The findings align with previous research showing surgery success rates around 90% for this condition in early-to-moderate stages.
What the Results Show
Before surgery, the patient could only eat liquids and had lost 5 kilograms of body weight. Her esophagus was severely enlarged (measuring 7 centimeters across) with a narrowed opening at the bottom—a condition called megaesophagus. Food and contrast dye were getting stuck inside, confirming the diagnosis.
The surgical procedure took 2 hours and went smoothly without complications. The patient was discharged from the hospital within 24 hours. Within 5 weeks of surgery, she progressed from a zero diet (nothing by mouth) to eating a completely normal diet. By February 2024, she reported no swallowing symptoms at all and had gained back 2 kilograms of the weight she had lost.
This dramatic improvement shows that the surgical approach—cutting the tight muscle at the bottom of the esophagus—successfully relieved the blockage and restored normal swallowing function. The patient’s quality of life improved significantly, as she could eat normally again without fear of food getting stuck or coming back up.
The case also revealed important information about Chagas disease complications. The patient had been treated for acute Chagas disease in 2004, but 15 years later, she developed severe digestive problems from the same infection. This shows that even after treatment, the parasite can cause lasting damage to the nerves controlling the esophagus. The case also documented the challenges patients face: diagnostic delays (3 years between symptom onset and imaging), limited access to specialized care, and the impact of COVID-19 on healthcare delivery in vulnerable populations.
Research shows that laparoscopic cardiomyotomy (the surgery performed) has about a 90% success rate for treating megaesophagus caused by Chagas disease when the condition is in early-to-moderate stages (Rezende classification groups I-III). This patient’s excellent outcome aligns with those published success rates. However, most previous studies involve larger groups of patients, whereas this is a single case. The case also emphasizes that early diagnosis and treatment of acute Chagas disease can prevent these severe digestive complications from developing in the first place.
This is a single patient case, so we cannot know if the same results would happen for other patients. The patient had an ideal outcome, but not everyone may recover as quickly or completely. The case took place in Brazil’s public health system with specific resource limitations, so results might differ in other healthcare settings. The long delay in diagnosis (3 years) makes it unclear whether earlier detection would have changed the outcome. Finally, this case report cannot prove that surgery is better than other treatments—it only shows what happened to this one person.
The Bottom Line
For people with Chagas disease: Get screened and treated early, especially in endemic areas. If you develop swallowing problems, seek medical evaluation promptly rather than waiting. For patients with Chagas-related megaesophagus: Laparoscopic cardiomyotomy appears to be an effective surgical option when swallowing problems significantly impact quality of life. Discuss this option with a gastroenterologist or surgeon experienced in treating Chagas disease complications. (Confidence: Moderate—based on this case and previous research showing 90% success rates)
People living in or from Central and South America where Chagas disease is common should care about this research. Anyone with a history of Chagas disease who develops new swallowing problems should discuss this case with their doctor. Healthcare providers in endemic regions should be aware that Chagas disease can cause long-term digestive complications decades after initial infection. Public health officials should note the importance of early screening and treatment to prevent these complications.
In this case, symptom improvement began immediately after surgery, with major dietary improvements within 5 weeks. Complete symptom resolution occurred by 5 months post-surgery. However, individual recovery timelines may vary.
Frequently Asked Questions
Can Chagas disease cause swallowing problems years after treatment?
Yes. This case shows a patient developed severe swallowing difficulties 15 years after being treated for Chagas disease. The parasite damages nerves in the esophagus, causing long-term digestive problems even after the initial infection is treated.
What is megaesophagus and how does it happen?
Megaesophagus is an abnormally enlarged food pipe. In Chagas disease, the parasite destroys nerves that control esophageal muscles, causing the pipe to dilate and lose its ability to push food down normally, leading to food getting stuck.
Is surgery effective for Chagas-related swallowing problems?
This case demonstrates that laparoscopic cardiomyotomy (surgical cutting of the tight muscle at the esophagus bottom) can be highly effective, with the patient progressing from liquid-only diet to normal eating within 5 weeks and achieving complete symptom relief.
How common are digestive complications from Chagas disease?
The case report doesn’t provide prevalence data, but it emphasizes that digestive complications are underreported in endemic regions. Early treatment of acute Chagas disease can prevent these chronic complications from developing.
What should I do if I have Chagas disease and develop swallowing problems?
Seek medical evaluation promptly rather than delaying care. Diagnostic imaging and specialist consultation are important. If conservative treatments don’t work, discuss surgical options like cardiomyotomy with a gastroenterologist or surgeon experienced in Chagas disease complications.
