Vector manometric study of the sphincter of Oddi in the dog: Functional and morphological correlation

The relationship between sphincter of Oddi pressure and the morphological structure of the sphincter was studied in eight dogs prepared with a duodenal cannula. Sphincter of Oddi manometry was performed in awake animals in three directions, ventral, left dorsal, and right dorsal, using a catheter with three radial side holes for recording at one level. The pressure in the ventral direction (26.6 ± 1.06 mmHg) (mean ± SEM) was significantly lower than that in the left and right dorsal directions (30.6 ± 1.42 and 31.2 ± 1.23 mmHg, respectively). This functional manometric difference in the three directions correlated closely with the morphological structure of the sphincter of Oddi; the sum of the thickness of the sphincter of Oddi muscle and duodenal proper muscle was greater on the dorsal than on the ventral side. To our knowledge, this is the first report of axial asymmetry in sphincter of Oddi pressure. (Received May 27, 1997; accepted April 24, 1998)     

低位直肠癌保肛手术临床价值分析

目的：分析并研究低位直肠癌保肛手术临床应用效果。方法将该院于2011年4月—2013年5月所救治低位直肠癌患者60例作为该次研究对象,平均分成两组（保肛组、非保肛组）,每组30例患者,保肛组患者给予低位直肠癌保肛治疗,非保肛组实施非保肛手术,观察两组患者临床手术结果。结果经相应手术治疗后,两组患者临床症状均明显变化,保肛组患者医治结果、肛门功能等和非保肛组患者相比,差异无统计学意义,P>0.05;保肛组患者并发症发生率、围术期治疗指标均优于非保肛组患者,P<0.05,两组间差异具备统计学意义。结论借助保肛手术治疗低位直肠癌患者,临床效果显著,可降低并发症发生率,提高生活质量,值得推广使用。     

临床超低位的直肠癌保肛手术中腹腔镜下ISR应用效果研究

目的：分析临床超低位直肠癌保肛手术（SSO）中实施腹腔镜下经肛门括约肌间切除术（ISR）的临床效果。方法：选取本院收治的超低位SSO患者80例作为研究对象,随机分为两组,每组40例。对照组实施开腹处理,而研究组实施腹腔镜下ISR处理,观察记录两组患者手术时间、术中出血量、住院时间、并发症发生率,并对比分析。结果：研究组手术时间、术中出血量、住院时间、并发症发生率均明显优于对照组,前后比较差异具有统计学意义（P<0.05）。结论：超低位直肠癌保肛手术患者实施腹腔镜下ISR治疗可取得良好的效果,所需手术时间短、出血少、住院时间短以及并发症发生率低,值得临床推广应用。
