CLINICAL FEATURES: A 44-year-old diabetic and alcoholic restaurateur of Chinese-Malay origin, who had been living in Australia for over 20 years, was admitted to hospital with bloody diarrhoea which progressed to fulminant toxaemia and circulatory collapse, and ultimately required laparotomy. Typical pathological features and the isolation of Clostridium perfringens type C from faeces confirmed the diagnosis of enteritis necroticans.
INTERVENTION AND OUTCOME: He was treated initially with ampicillin, gentamicin, metronidazole and chloramphenicol, and later with penicillin and metronidazole, and he required large volumes of intravenously administered fluid and blood for his toxaemic, hypotensive state. Laparotomy was performed as a life-saving procedure. Despite a lengthy convalescence, the patient recovered.
CONCLUSIONS: Enteritis necroticans is a rare disease in developed countries, however it is likely to be underdiagnosed. Clinicians are encouraged to be on the alert for signs of severity that may indicate the need for laparotomy in a predisposed individual with features of this condition.
Case presentation: We present a rare case of adult intussusception who presented with a triad of intestinal obstruction. Computed tomography revealed small bowel intussusception with bowel ischemia. Intraoperatively, she required resection of the small bowel and primary anastomosis. Macroscopic examination revealed a single pedunculated polyp, which is the lead point of intestinal obstruction and confirmed histologically.
Conclusion: Inflammatory fibroid polyp should be considered as a cause of intussusception among adults with small bowel obstruction.
METHODS: A cross-sectional study of consecutive adult patients who underwent glucose hydrogen breath test was conducted. Factors associated with SIBO were evaluated. Symptom severity and HRQoL of IBS patients with and without SIBO were compared. The independent factors associated with severe IBS were explored.
RESULTS: A total of 160 patients were included (median age 40 years, males 31.3%). IBS was present among 53.8% of subjects, with 33.8% having diarrhea-predominant IBS (IBS-D). SIBO was diagnosed in 22.5% of the study population. Patients with SIBO were more commonly diagnosed with IBS-D than those without (50.0% vs 29.0%, P = 0.019). Severe IBS was associated with SIBO (36.4% vs 15.6%, P = 0.043). SIBO was associated with poorer HRQoL (Euroqol five-dimensional utility score: 0.73 vs 0.80, P = 0.024). SIBO (44.4% vs 20.6%, P = 0.043), anxiety (77.8% vs. 39.7%, P = 0.004), and depression (50.0% vs 19.1%, P = 0.011) were associated with severe IBS in the univariate analysis. However, SIBO was the only independent factor associated with severe IBS in the multivariate analysis (adjusted odds ratio 3.83, 95% confidence interval CI 1.02-14.34, P = 0.046).
CONCLUSIONS: There was a significant association between IBS-D and SIBO. The coexistence of SIBO had a significant negative impact on IBS patients.
