At low magnification , a colonic diverticulum has a central lumen with surrounding mucosa , while the wall ( lacking a muscularis ) is attenuated . the narrow neck of the diverticulum may become eroded 低倍镜下，结肠憩室有内覆粘膜的中心腔，然而腔壁（因缺少肌层）是薄弱。憩室的窄颈可能会被侵蚀破坏。
Pressure of the prostate to the urethra may bring other urologic disease such as urethritis or bladder inflammation , vesical calculus or bladder diverticulum etc . all of these pathological changes also arose the hematuria 前列腺增生对尿道的压迫还可以合并泌尿道的其它病变，如尿道膀胱的炎症，膀胱结石膀胱憩室等等，这些病变也可以引起
Usually of little clicinal significance , it can produce a variety of disorders such as malabsorption , hemorrhage , diveticulitis , and obstruction . the rares complications appears to be enterolith formations and obstruction 十二指肠憩室病造成肠阻塞时，其机转可能是肠黏连，扭结，套叠或蠕动不良，另一极少见的原因则是肠石形成而造成肠阻塞。
Besides , the pressure to urethra owing to bph also results in other inflammation of urinary system such as urethritis , cystitis , bladder stones and bladder diverticulum etc , and these illnesses also bring hematuria 另外，前列腺增生对尿道的压迫还可以合并泌尿道的其它病变，如尿道膀胱的炎症，膀胱结石膀胱憩室等等，这些病变也可以引起血尿。
By the location , relationship to adjacent tissue and origin of tubular structure , the sonographic findings were differentiated from those of other similar diseases , such as colonic duplication or meckel ' s diverticulum 而我们根据管状结构所在的位置、管状结构跟邻近组织的相关性以及此管状结构从肠胃道的起源处这些特性，可跟梅克尔憩室或者结肠复制异常的超音波影像做?别诊断。
About 30 to 40 per cent of people over 50 have it , though most have no symptoms . others experience bleeding , constipation , diarrhea , flatulence , pain , or diverticulitis that s when the pouches - or diverticula - that form in the walls of the colon get inflamed 虽然多数的人没有什么症状，有些人则有出血便秘腹泻胃胀气疼痛或是憩室炎这是由于在结肠壁形成的小囊，或称憩室，其发炎所造成的等症状。
Constipation - straining to pass small hard stools - causes a build - up of muscular pressure in the bowel . eventually , constant pressure causes weak spots or blow - outs in the wall , which can become inflamed and painful . this is how haemorrhoids and diverticular disease develop 当便秘要用力排出小量硬便时，对肠壁肌肉会造成压迫，长期的压迫最后会形成局部肠子的弱点或肠子向外鼓出，这些地方容易引起发炎和疼痛，于是产生了痔疮和憩室炎。
In - soluble fibre helps solid wastes pass through the body more efficiently , and thereby reduces exposure of the intestines to toxic substances that can cause intestinal cancer . this kind of fibre also prevents or reduces the severity of constipation , hemorrhoids , and diverticulosis 非水溶性食物纤维能加速使粪便排出体外，直接减少废物在肠道停留时间，减低有害致癌物质在肠脏积聚，能预防肠道癌，避免便秘、痔疮及憩室病的出现或恶化。
