Rationale:
Strongyloides stercoralis, a rare human intestinal parasite, poses a significant health risk, capable of causing lifelong infection and even mortality due to its atypical manifestation of symptoms. In this case report, we reported a case of a patient diagnosed with S. stercoralis infection of the residual stomach and meticulously detail its treatment process, offering valuable insights and a reference point for clinicians.
Patient Concerns:
we report a case of infection caused by S. stercoralis after subtotal gastrectomy (Billroth type II) in a 47-year-old middle-aged man. It presents with recurrent nausea and vomiting, accompanied by intermittent food residue vomiting and constipation.
Diagnoses:
Upon endoscopic examination, we observed mucosal swelling and erosion in the anastomosis and output ring of stomach, while pathological analysis confirmed the presence of Strongyloides stercoralis eggs. Subsequently, the administration of albendazole for anti-infection treatment proved to be effective, thereby reinforcing the diagnosis of S. stercoralis infection.
Intervensions:
The patient underwent aggressive management including fasting, fluid replacement, anti-infection therapy, albumin supplementation, and albendazole treatment at a dose of 300 mg/kg/day for 3 days to eliminate the parasite.
Outcomes:
After treatment, the patient's symptoms of nausea, vomiting, and constipation were alleviated and returned to normal upon discharge. Over the subsequent 3 years, the patient reported no instances of vomiting and experienced a recovery of digestive function compared to their discharge status.
Lessons:
S. stercoralis infection is relatively rare in the remnant stomach, endoscopic and pathological examination may be one of the important methods to diagnose S. stercoralis infection, and it is effective to treat albendazole according to the course of treatment.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
01:17Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
