【摘要】：目的:探討主胰管胰頭段水平角及開角方向與急性胰腺炎的相關(guān)性。方法:回顧性連續(xù)搜集臨床及上腹部MRI檢查診斷為急性胰腺炎的213例患者的臨床資料,按納入和排除標(biāo)準(zhǔn)入選60例(其中男38例,女22例,平均年齡45歲)為觀察組,同期收集43例正常胰腺(男22例,女21例,平均年齡53歲)為對照組。兩組均行MRCP,數(shù)據(jù)上傳至工作站行圖像處理,在主胰管顯示清晰完整的層面上連續(xù)三次測量主胰管胰頭段及主胰管頭尾兩端連線與水平線的夾角,記錄平均數(shù)值及主胰管胰頭段水平角方向并行統(tǒng)計(jì)學(xué)分析。結(jié)果:急性胰腺炎組,主胰管胰頭段及主胰管頭尾兩端連線與水平線的夾角分別為25.64°±20.32°和28.07°±11.11°,而正常胰腺組為30.56°±18.56°和28.65°±10.49°(t=1.254/0.253,P=0.213/0.801)。60例急性胰腺炎組中,主胰管胰頭段開角向上36例,主胰管胰頭段與水平線的夾角為32.19°±23.19°,向下24例,其夾角為16.08°±8.80°;43例正常胰腺組,開角方向上37例,主胰管胰頭段與水平線的夾角為32.77°±18.91°,向下6例,其夾角為16.94°±7.66°。急性胰腺炎組與正常胰腺組,向上或向下開角方向,主胰管胰頭段與水平線的夾角差異均無統(tǒng)計(jì)學(xué)意義(t=0.117/0.219,P=0.907/0.828),而主胰管胰頭段與水平線的開角方向差異具有統(tǒng)計(jì)學(xué)意義(χ2=8.232,P=0.004)。全部病例中向上開角的角度(32.48°±20.98°)與向下開角的角度(16.26°±8.46°)間差異有統(tǒng)計(jì)學(xué)意義(t=4.901,P=0.000)。結(jié)論:急性胰腺炎與主胰管胰頭段水平角大小無關(guān),但與水平角的開角方向密切有關(guān),臨床急性胰腺炎多以開角向下方向?yàn)橹鳌?br/>[Abstract]:Objective: to investigate the correlation between the horizontal and open angle of the pancreatic head segment of the main pancreatic duct and acute pancreatitis. Methods: the clinical data of 213 patients with acute pancreatitis diagnosed by clinical and epigastric MRI were collected retrospectively. According to the criteria of inclusion and exclusion, 60 cases (38 males and 22 females, mean age 45 years) were selected as the observation group. 43 cases of normal pancreas (22 males and 21 females, mean age 53 years) were collected as control group. The MRCP, data of both groups were uploaded to the workstation for image processing. The angles between the head of the main pancreatic duct and the ends of the head and tail of the main pancreatic duct and the horizontal line were measured three times on the clear and complete layer of the main pancreatic duct. The mean value and the horizontal angle of the pancreatic head of the main pancreatic duct were recorded and analyzed statistically. Results: in the acute pancreatitis group, the angles between the head of the main pancreatic duct and the ends of the head and tail of the main pancreatic duct were 25.64 擄鹵20.32 擄and 28.07 擄鹵11.11 擄, respectively, compared with 30.56 擄鹵18.56 擄and 28.65 擄鹵10.49 擄in the normal pancreas group. The angle between the head of the main pancreatic duct and the horizontal line was 32.19 擄鹵23.19 擄, and the angle was 16.08 擄鹵8.80 擄in 43 cases of normal pancreas. The angle between the head of the main pancreatic duct and the horizontal line was 32.77 擄鹵18.91 擄and 16.94 擄鹵7.66 擄in 43 cases of normal pancreas group, and the angle between the head of the main pancreatic duct and the horizontal line was 32.77 擄鹵18.91 擄, and the angle of the angle was 16.94 擄鹵7.66 擄. There was no significant difference between the acute pancreatitis group and the normal pancreas group in the angle of opening up or down, the angle between the head of the main pancreatic duct and the horizontal line (t = 0.117 / 0.219g / 0.9070.828), but there was a significant difference in the opening angle between the head of the main pancreatic duct and the horizontal line (蠂 28.232P0. 004). There was significant difference between the angle of upward opening (32.48 擄鹵20.98 擄) and the angle of downward angle (16.26 擄鹵8.46 擄) in all cases (t = 4.901). Conclusion: acute pancreatitis is not related to the horizontal angle of the pancreatic head segment of the main pancreatic duct, but is closely related to the opening angle direction of the horizontal angle.
