  7. i wanna ask about somethings in history ..

    are there attacks of diarrhea in between the attacks of constipation ?? , bloody stool ??

    and i wanna do colonoscopy ...

    By the way ,
    My diagnosis is , " Cancer colon "

    and all above is for confirmation .. :-)

  8. And also i wanna work on a 2nd line ,

    i wanna ask about past vascular problems ..

    as also in old age with a such presentation , i should suspect vascular occlusion ..

    but i think the case is toward Colon cancer ..

  17. clinical hx suggests large intestinal obsstruction.
    DD list
    He might have chronic constipation due to CA descending colon or sigmoid colon or old age associated with poor dietery habits.He did not have a Hx of per rectal bleeding.So CA can be excluded.
    Adhesions,Sigmoid Volvulus are the other possible DDs.
    Long term of laxative use - megacolon

  22. Jerry87 Says:
  23. tc scan can revele the diagnosis,ca colon,ischemian,volvolus or irritable colon syndrome

  35. chronic laxative use can lead to dependence, leading to bowel relaxation, therefore further worsening constipation in the long run. also, laxatives can cause colon cancer, in which there would be decrease in the diameter of stools/obstruction in the colon and may be misdiagnosed as functional constipation.

    for this patient i would request for colonoscopy for confirmation, also decompression by inserting NGT to prevent intestinal rupture, which could lead to sepsis.

    if there is already an intestinal rupture, exploratory laparotomy should be done STAT.

  37. Ultrasound can also be done to view the mass. the mass could either be fecal stasis or an actual tumor which could be malignant as resulting from laxative overuse.

    always base your diagnosis on the History and PE. Laboratory findings are always secondary. The chronic laxative use was already a giveaway.

  39. overuse of laxatives can lead to diarrhea which leads to loss of electrolytes like potassium. hypokalemia would then occur which would alter intestinal motility therefore causing constipation, fecal stasis and retention of gases.

  41. sometimes in colon cancer, blood in stool is not always seen grossly. blood in stool can be identified through occult blood. therefore, laboratories would only be confirmatory, but NOT THE BASIS OF THE DIAGNOSIS. History and PE must always be the basis of the diagnosis, not laboratories.
