The subject experienced ileus (hospitalization) on 06Jun2017 with outcome of recovering. The patient underwent lab tests and procedures which included abdominal X-ray: colonic distention on 02Jun2017, abdominal X-ray: ileus on 04Jun2017, abdominal X-ray: stable ileus on 05Jun2017, computerised tomogram abdomen: mild ileus; no bowel obstruction on 05Jun2017. Therapeutic measures were taken for the event included milk and molasses enema from 02Jun2017 to 02Jun2017 and Smog (saline, mineral oil, glycerin) enema from 04Jun2017 to 04Jun2017.  The clinical course was as follows: the subject with acquired flat back syndrome and lumbar stenosis, who underwent a T11-pelvis posterior instrumented fusion with an L3-4 and L6-S1 transforaminal lumbar interbody fusion on 30May2017. Post op course was initially unremarkable with the exception of abdominal distention that began on 02Jun2017, and constipation. Abdominal x-ray done on 04Jun2017 confirmed post-op ileus. Acute care surgery was consulted. Subject was made NPO and received 2 enemas. A nasogastric tube was placed on 05Jun2017. On 06Jun2017, subject reported improving symptoms, including having a bowel movement and reduced abdominal discomfort, and the nasogastric tube was removed. The diagnosis of ileus was determined to be progression from an adverse event to a serious adverse event due to prolongation of the subject's expected length of stay (7 days) post-op. The subject remains hospitalization as of 06Jun2017. The investigator considered there was not a reasonable possibility that the event was related to the study drug SA4Ag vaccine or placebo, concomitant drugs and clinical trial procedure. The reporter's assessment of the causal relationship of the event with the suspect product PREVNAR 13 was not provided at the time of this report. Since no determination has been received, the case is managed based on the company causality assessment. Sender's Comments: The company agrees with the assessment of the investigator and does not attribute the case to study therapy based on the information currently available, the known adverse event profile of the suspect product and the pathophysiology of the event.
