Abstract:
Objective:To analyze the value of small bowel manometry in assessing duodenojejunal motility in patients with superior mesenteric artery syndrome (SMAS).Methods:The clinical data of 13 patients with SMAS in the Fourth Affiliated Hospital of Nanjing Medical University from October 2019 to October 2023 were retrospectively analyzed. Small bowel manometry was routinely performed after admission.Results:Among the 13 patients, body mass index<18 kg/m 2 was in 9 cases; 8 cases required enteral or parenteral nutritional support; abdominal pain and distension were the sole initial symptoms in 7 cases, with constipation as the initial symptom in 5 cases. The small bowel manometry result showed that 11 cases had abnormal duodenojejunal motility. Among the 5 cases with constipation as the initial symptom, 4 cases exhibited absence of migrating motor complex Ⅲ phase. Conclusions:Duodenojejunal dysmotility may be commonly present in patients with SMAS. Some cases of SMAS might be secondary to underlying intestinal motility disorders.
