Introduction and importanceBezoars result from undigested material having an incidence of 0.4–1% (Gunner et al., 2012). Impaired gastrointestinal motility is one of the risk factors. The aim of this article is to highlight the importance of this commonly disregarded entity as well as the different treatment modalities available.Case presentationA 68-year-old female presented to our emergency department complaining of colicky lower left abdominal pain associated with vomiting and absence of bowel movements for the past 4 days. She had a previous history of a subtotal gastrectomy due to gastric cancer. The physical examination revealed a lower left quadrant palpable mass. Abdominopelvic CT scan showed distension of the gastric remnant with anastomotic obstruction caused by a bezoar. Attempted endoscopic dissolution of the bezoar was unsuccessful. The patient then underwent surgery enterotomy proximal to the obstruction with extraction of the mass.Clinical discussionBezoars are responsible for 0.4%–4% of cases of mechanical gastrointestinal obstruction (Dikicier et al., 2015). Contrast-enhanced CT scan is the best diagnostic test with a sensitivity and specificity of 90% and 57%, respectively (Kim et al., 2003). Treatment options differ according to the type, size and location of the bezoar as well as clinical presentation. Conservative measures such as chemical dissolution and endoscopic fragmentation and extraction can be used with surgery being usually required for a bezoar-induced gastrointestinal obstruction.ConclusionThe clinical findings of bezoar-induced ileus do not differ from the other different causes of mechanical intestinal obstruction. Hence, a high grade of suspicion and an early radiological exam are the keys for a prompt diagnosis and treatment. 相似文献

The purpose of this case report is to describe the events, intervention, and aetiology which led to acute airway obstruction in an adult patient after the placement of a Hickman catheter. Airway obstruction secondary to superior vena cava obstruction occurred after placement of a subclavian vein Hickman catheter. This was felt to occur, in part, to a narrowed superior vena cava as evident by subclavian venography. It resulted in emergency oral tracheal intubation to relieve airway obstruction. Shortly after removal of the Hickman catheter, the signs of superior vena cava obstruction syndrome resolved and the patient was extubated without incidence. It is concluded that, although rare, the serious complication of acute airway obstruction can occur after placement of a Hickman catheter. 相似文献

Involvement of the pulmonary artery by echinococcosis usually occurs due to pulmonary embolization after rupture of the cyst in the right ventricle or, rarely, by dissemenation from a hepatic focus. This paper presents an adult patient with intramural hydatid cysts of the pulmonary arteries, which apparently grew slowly toward the lumina resulting in complete luminal occlusion, enabling sufficient time for development of sufficient perfusion from the bronchial arteries. The condition apparently resulted from embryos of the parasite, which entered the vasa vasorum of the pulmonary arteries, a previously unreported mechanism. 相似文献

Effect of aging on bladder function and the response to outlet obstruction in female rats 总被引:3,自引:0,他引:3
Bladder dysfunction in the aging population is a significant problem. However the concomitant presence of other diseases
in many patients can make it difficult to distinguish between changes in bladder function and other influences. The present
study was designed to study, in aging rats, bladder function and the effect of partial bladder outlet obstruction (BOO) on
bladder function. Cystometrics were performed in awake, female Fischer 344 rats of four age groups (6, 12, 18 and 24 months)
following subcutaneous implantation of a mediport catheter. Cystometric evaluations were carried out in control rats or those
subject to three weeks of BOO. Bladder compliance significantly decreased with aging, which reflected an increase in threshold
pressure without changes in bladder capacity. Partial BOO caused development of severe bladder instability. Following BOO,
bladder capacity and compliance were significantly increased in all age groups. Threshold pressure was lower in obstructed
animals, except for 6-month rats. Younger animals were able to generate a higher contraction pressure to compensate for the
BOO, whereas older animals did not. Using an awake model of cystometric measurement, we have demonstrated that aging, by itself
can affect bladder function. Furthermore, aged animals respond differently to BOO than younger animals. These results demonstrate
that both aging and disease can contribute to bladder dysfunction, and suggest that treatment of bladder dysfunction may require
a combination of therapies targeted to multiple etiologies.
