Solid-Phase Gastric Emptying Time in Gastric and Duodenal Ulcer Patients

胃潰瘍及十二指腸潰瘍病患固態胃排空時間之研究

摘要


造成消化性潰瘍的原因很多,除了傳統的胃酸分泌過多之外,胃蠕動異常也是重要的因素之一。本試驗在分析國人胃潰瘍及十二指腸潰瘍病患固態胃排空時間之變化,進一步分析潰瘍位置及潰瘍程度對排空時間的影響。選擇胃潰瘍大於0.5公分之病患14人(mean age, 64.1 range 43-72)為第一組,十二指腸潰瘍病患14人(mean age, 49.1 range 30-76)為第二組,合併胃潰瘍及十二指腸潰瘍病患10人(mean age, 66.5 range 61-73)為第三組,排除合併其它身體重大心臟、肺臟等疾病,及壓力性潰瘍之病患與正常人25人(mean age, 31.2 range 27-40)為對照組比較。空腹一天後,做固態食物胃排空檢查。以Tc-99m phytate 500μCi混合炒蛋二個,土司麵包二片,加葡萄糖水150cc給病人食用後,病患平躺,每隔10分鍾,以珈瑪照像機(Elscint Apex609R),左前側位偵側共90分鍾。結果胃潰瘍病患胃排空時間Tl/2平均值(mean, 136.9±49.4mim) ,十二指腸潰瘍病患(146.0±52.9)與正常人(88.7±14.2)比較,P值各為0.001及0.0004有統計意義,而二組比較,無統計意義。以胃潰瘍位置與胃排空時間比較,分johnson type 1(胃體+胃角), type2(胃,十二指腸潰瘍)及type 3(胃竇)三組,type 1組(127.4±51.0)與type2組(86.4±38.1),type1和type3 (149.6±48.6)比較,無統計意義,但type1,type3組與正常組比較P值各爲0.002及0.005都有統計意義。以胃潰瘍程度比較,分A(活動期)及H(愈合期+結枷期)二組,A組(155.7)與H(愈合期+結枷期)二組,A組(138.8±54.9)與H組(134.9±47.6)無有統計意義。以十二指腸潰瘍程度比較,A組(168.3±41.6)與H組(90.2±33.4)P=0.014無有統計意義。以第三組十二指腸潰瘍程度比較,雖然活動期(107.0±35.3)比愈合期(65.8±40.0)延長,但無統計意義P=0.12。 本試驗顯示胃潰瘍及十二指腸潰瘍病患固態胃排空時間有延長的現象,所以胃蠕動異常與消化性潰瘍有很密切的關係。1980年Miller lj, et al.曾提出johnson type 1 gastric ulcer(潰瘍挶限於胃體及胃角)固態胃排空時間延長,認爲是胃竇蠕動異常的結果,本實驗得到相同的結果。至於胃竇潰瘍及幽門旁潰瘍胃排空時間延長可能阻礙胃排空路徑的結果。十二指腸潰瘍活動期與愈合期十二指腸潰瘍延長,故推論是潰瘍活動期胃粘膜發炎水腫阻礙了胃排空路逕的結果。 結論:胃體及胃角潰瘍固態胃排空時間延長,是原發性胃竇蠕動異常的結果,至於胃竇潰瘍,活動性十二指腸潰瘍,胃潰瘍合併活動十二指腸潰瘍胃排空時間延長,是繼發於活動期胃粘膜發炎水腫阻礙了胃排空路徑的結果。

並列摘要


Solid-phase gastric emptying time was measured in 14 patients with gastric ulcer, 14 patients with duodenal ulcer, and 10 patients with gastric ulcer and duodenal ulcer. Those were compared with the results from 25 healthy volunteers. The test meal contained two eggs, labelled with 500μCi 99mTc-DTPA, two pieces of toast, and 150cc 5% glucose water. Gamma camera imaging proceeded over 90min, with 10min frame time. Gastric emptying time was significantly delayed in the gastric ulcer group (P=0.001), including corpus ulcer (P=0.02) and antral ulcer (P=0.005), and in the active duodenal ulcer group (P<10^(-5)). Gastric emptying was normal in healed duodenal ulcers. These results suggest that delayed gastric emptying in corpus ulcer is due to primary antral dysfunction, and delayed gastric emptying in the active ulcer stage may be secondary to ulcer mucosal inflammation and swelling.
