As hep as people " colonic cancer " , " rectum cancer " photograph comparing, small intestine tumour should be gotten less much. Small intestine tumour is made an appointment with 30 a variety of, cent is benign and malign two kinds, see more at the old people in 50 years old of above, male of incidence of a disease female of summary prep above.

Although small intestine is very long, but it is human body however in grow lesser one of organs of tumor, because there are 3 physiology factors that differ with colon inside antrum of small intestine bowel:

1. Fluid shape all is when small intestine is being entered after food classics stomach is digested, reduced the concentration of carcinogen so.

2. The bacterium inside small intestine is less, the carcinogenic substance that creates by the bacterium is opposite little also.

3. There is protection inside small intestine enzymatic wait for material with immune globulin, these material all can make the carcinogen inside alvine antrum reduces toxin.

Because small intestine tumour is scarce, its pathogeny research is less also, the pathogeny still is clear about not completely. Adenoma of path of partial stomach bowel and heredity are concerned. Immune globulin blemish or the patient that accept immunity to restrain cure, the on the high side of incidence of a disease of small intestine tumour. At present already AIDS patient produces small intestine the report of malignant tumor.

　 Symptom of patient of small intestine tumour is great

Because tumor grows,sort of place, pathological changes reachs accident of course of diseases to wait a lot of and different, its are clinical the symptom has a characteristic each. After occurrence tumour of small intestine upside, the patient can have instead acerbity, heartburn, vomiting, icteric wait for expression; If bowel,produce intussusception, can appear intestinal obstruction; Still have calorific, angular, bellyacke, diarrhoea additionally, n/med having blood in one's stool, anaemia; Individual patient shows in ministry of oral cavity mucous membrane, lip and hand end has small pigment spot. Small intestine tumour is inchoate and clinical symptom constant not apparent, be easily by examine other disease. From medical data the analysis looks, defer of regular meeting of time of diagnose of small intestine tumour 7 ～ 9 months or longer. So, should encounter have a reason unidentified intestinal obstruction or when n/medding having blood in one's stool, what should consider small intestine tumour is likely.

　　 Small intestine is benign tumor

Flowing flesh tumour is the benign tumor with common small intestine, tumour body grows inside Xiang Chang antrum, its are bulgy the ministry is easy produce ulcer and cause n/med having blood in one's stool.

Adenoma is called more " polypous " , the appearance submits pear form, pear handle is called " the base of a fruit " , small intestine polyp contains the base of a fruit more, this facilitates inside excise its below lens. The size of adenoma is differ, small person the diameter is a few millimeter only, big person can amount to 3 ～ 5 centimeters; But single shot, also can send more. Adenoma grows in duodenum and ileum more, but drag in a paragraph of small intestine or complete small intestine, sometimes but drag in is whole gastric bowel path. Accordingly, when discovering duodenum has polyp to grow, check stomach, small intestine even have inside other position and large intestine without polyp. Small intestine polyp belongs to the pathological changes before cancer, if not seasonable discovery is excised, canceration can happen after tumour body increases. Polyp of upside small intestine still needs to check regularly after the excision below lens inside. Still can remove polyp without medicaments at present or prevent its recurrent.

Lipoma is single shot more, size differs, have occasionally tremendous person, in small intestine end paragraph (ileum) common.

Although hemangioma is not true tumour, but because can be caused,bleed and be taken seriously. Hemangioma is congenital deformation, small intestine hemangioma is scarce.

　　 Small intestine is malign tumor

Malignant tumor incidence of a disease compares large intestine small intestine tower above a few times. Small intestine is malign tumor is less, see more at old people. Malignant tumor is in of ileum place occupy 49% , in duodenum person occupy 23% .

Gland cancer often happens in duodenum far end or small intestine upside. Head hair symptom is mixed to n/med having blood in one's stool intestinal obstruction. The lens inside many patient have the aid of can do visit a patient at home to break.

Malign and lymphatic tumour occupies 1/4 in tumour of lymphatic tumour small intestine, need undergo surgery is excised and do change cure.

Kind cancer kind cancer is some lower than malign degree of cancer, can happen in the body any parts, in gastric bowel the commonnest, be like appendix, rectum and ileum. Gastric bowel kind of cancer is much grow slow, course of diseases is longer, because tumour system is small, not easy examine sees when the examination, there already often was hepatic move when diagnose so.

Flowing muscle tumour grows in small intestine end more paragraph, tumour put oneself in another's position is larger. N/med having blood in his stool to often head hair symptom.

　　 Tumour of diagnose small intestine needs to make what inspection

Radiography of agent of X line barium is as long as 7 meters as a result of small intestine, the speed when baric agent is passed slants again fast, the jackknife that plus bowel is affected, all bring a lot of difficulty to examination of small intestine tumour, often do not watch tumour system. Use the tracheal section examination that contains gasbag at present, diagnose correctly rate already had rise.

It is not difficult to the examination of pathological changes of small intestine upside that lens inspects gastroscope and duodenum looking glass inside, and can undertake pathology draw materials or swollen content are excised. Examination of small intestine lens is on the operation difficulty is greater, examination time is longer, heretofore is in clinical on have not popularize use.

The lens inside capsule is check an instrument newly in recent years. Diagnose conduce to pathological changes of partial small intestine, but if encounter largish tumour body, the likelihood when capsule be issued to lower levels suffocate suffocate, produce intestinal obstruction even.

Paunch probes a reason to n/med having blood in his stool unidentifiedly patient, via checking the person that fail to decide pathological changes place or pathological changes are serious with all possible means, impossible redo is other when the examination, need a paunch to probe, the operation may save patient life.

　　 The cure of small intestine tumour

The benign pathological change that lens of gastroscope, duodenum can see, most patient but excision of body of tumour of travel of the lens inside classics. If inside be hard to excise below lens or the tumour of other position needs small intestine a surgical operation cure. Malignant tumor already had small intestine when move, cure is relatively difficult, require the specific patient's condition according to the patient, treat plan by doctor and family member make choice of.
