A 70-year-old woman in Thailand recently experienced a startling medical complication – a live roundworm discovered in her esophagus during diagnostic testing for long-term difficulty swallowing. The unusual case, detailed in a study published December 23, 2028, highlights the risks associated with consuming improperly washed produce and serves as a reminder of the prevalence of parasitic infections even in regions with modern healthcare systems. Doctors successfully removed the worm and treated the patient, but the incident offers a rare glimpse into the migratory patterns of ascaris lumbricoides and the potential for unexpected complications.
Health trends are gaining momentum, prompting increased awareness of what we eat and how we care for our bodies.
On December 23, 2028, a case study was shared highlighting a severe illness in a patient traced back to dietary choices. The case involved a 70-year-old woman who experienced intermittent difficulty swallowing for four years, but her condition recently worsened, leading her to seek hospital care.
Doctors performed a barium swallow and X-ray, revealing a coiled, mysterious object in the esophagus. The object was identified as an Ascaris lumbricoides roundworm.
The patient’s four-year history of swallowing difficulties typically occurred when eating too quickly. She also experienced bloating, which subsided with vomiting, and therefore had not sought medical attention previously.
However, her symptoms intensified after consuming red bean paste and plum pastries. Despite attempting to induce vomiting, she continued to experience difficulty swallowing and persistent abdominal discomfort for three days before finally seeking care. Initial hospital examinations, including a physical exam and standard lab tests, were normal. Doctors then ordered a barium swallow – a diagnostic procedure using a contrast agent – followed by an X-ray. The imaging revealed a spiral-shaped mass obstructing the esophagus, though some passage remained. Doctors provided initial treatment and prepared the patient for an endoscopy (EGD).
The endoscopy revealed mild swelling of the lower esophagus and no obvious foreign body. However, upon reaching the stomach, doctors discovered the source of the problem: a live Ascaris lumbricoides roundworm still wriggling around. It’s believed the worm had migrated from the esophagus back into the stomach.
Further examination of the upper small intestine revealed two additional worms. The stomach and intestinal lining showed signs of inflammation. The patient’s medical history indicated she had previously passed worms in her stool and frequently consumed raw vegetables that may not have been thoroughly washed.
Treatment involved the anti-parasitic medication mebendazole, resulting in the passage of approximately five to six worms in the patient’s stool.
The worms found in this case belong to a group of large roundworms. Their eggs are commonly found in soil contaminated with feces and can be ingested through improperly washed fresh produce.
And through contaminated water. The life cycle of the worm involves the following stages:
-Ingestion of eggs
-Larval hatching in the intestines
-Penetration of the intestinal wall
-Entry into the bloodstream
-Travel from the intestines to the liver, then the lungs. The lungs are targeted because of their narrow blood vessels. The larvae then penetrate the air sacs in the lungs. In this case, the worm had already passed through the lungs, seeking to evade the robust immune defenses of the intestines (GALT).
The larvae eventually return to the intestines to mature. As they grow, the worms can migrate up the airways, triggering coughing and expectoration. If swallowed, they return to the intestines.
Once mature, these worms are resistant to the immune system and can reside in the body for extended periods, potentially obstructing bile ducts or even migrating to the stomach, where they can withstand stomach acid. The case of this patient reaching the esophagus is rare, as worms typically exit through the mouth.
It’s thought that the contractions of the stomach and intestines during eating may have caused the worm to temporarily become lodged in the esophagus. However, the red bean paste and plum pastries may have triggered an unusual migration, causing it to remain stuck for an extended period, ultimately requiring hospitalization.
The key takeaway from this case is:
Raw vegetables are nutritious, but they must be thoroughly washed. Worm eggs can indeed be present on raw produce. If you choose to eat raw vegetables, proper washing is essential.
