  Bowel Obstruction
Bowel obstruction is one of the most difficult processes to palliate, yet recent advances in understanding and new therapeutic approaches allow us to do a much better job than was possible only a few years ago.
Bowel obstruction is a very dynamic process, frequently reverting from total to partial obstruction and back in as many as 50% of cases.
A., patients with total distal bowel obstruction who probably would have died within days with traditional drip and suck therapy have been able to resume eating, improve their functional status, and be discharged to home, living for weeks to a few months post-obstruction.

  Reference.com/Encyclopedia/Bowel obstruction
Obstruction may be due to causes within the bowel lumen, within the wall of the bowel, or external to the bowel (such as compression, entrapment or volvulus).
Bowel obstruction may be complicated by dehydration and electrolyte abnormalities due to vomiting; respiratory compromise from pressure on the diaphragm by a distended abdomen, or aspiration of vomitus; bowel ischaemia or perforation from prolonged distension or pressure from a foreign body.
In malignant large bowel obstruction, endoscopically placed self-expanding metal stents may be used to temporary relieve the obstruction as bridge to surgery, or as palliation.

 s020325a - Small Bowel Obstruction
Intestinal obstruction in which the initial abdominal films tend to be either unrevealing or equivocal include high obstructions, including the superior mesenteric artery syndrome; presence of strangulation; partial small bowel obstruction; and fluid-filled proximal bowel.
In intestinal obstruction, characteristic roentgenographic findings with use of barium meal are normal to rather rapid transit time to the point of obstruction; homogenous dilution of barium in dilated proximal loops; and inhomogenous, scattered, and fragmented collections of barium in the distal, collapsed loops.
Small bowel obstruction was diagnosed by ultrasonography in 23 of 44 patients (52%), by plain abdominal film in 26 of 44 patients (59%), and by small bowel enema in 28 of 44 patients (64%); the diagnostic accuracy of plain abdominal film and ultrasonography compared with small bowel enema was 73% and 89%, respectively.

 InteliHealth:
In a bowel obstruction (intestinal obstruction), a blockage prevents the contents of the intestines from passing normally through the digestive tract.
If the obstruction is caused by a volvulus, the passing of this instrument into the bowel not only confirms the diagnosis, but also untwists the intestine and relieves the obstruction.
A complete bowel obstruction often requires surgery to correct or remove the cause of the obstruction (tumor, adhesions, stricture), repair the hernia, or fix the segment of intestine at risk of repeated volvulus.

A bowel obstruction of the large intestine (=colon), as mentioned above, is not as acute as that of the small bowel.
Treatment is similar to small bowel obstruction in that the patient has to be stabilized first and then a laparotomy is performed, which usually tells the surgeon exactly what is going on and the appropriate procedure can be done to correct it.

 Constipation, Impaction, and Bowel Obstruction
Constipation, impaction, and bowel obstruction are common problems for cancer patients, with causes that include the cancer itself or treatment of the cancer.
Bowel obstructions are classified by the type of obstruction, how the obstruction occurred, and where it is. Tumors growing inside or outside the bowel, and scar tissue that develops after surgery, can affect bowel function and cause a partial or complete obstruction.
** BOWEL OBSTRUCTION ** -- Description and Causes -- A bowel obstruction may be caused by a narrowing of the intestine from inflammation or damage to the bowel, tumors, scar tissue, hernias, twisting of the bowel, or pressure on the bowel from outside the intestinal tract.

Structural disorders, such as intraluminal and extraluminal bowel lesions caused by primary or metastatic tumor, postoperative adhesions, volvulus of the bowel, or incarcerated hernia, affect peristalsis and the maintenance of normal bowel function.
Small bowel obstructions are caused frequently by adhesions or hernias, whereas large bowel obstructions are caused commonly by carcinomas, volvulus, or diverticulitis.
If the bowel obstruction is thought to be functional (rather than mechanical) in origin, metoclopramide is the drug of choice due to its prokinetic effects on the bowel.

Obstruction of the small bowel leads to proximal dilatation of the intestine due to accumulation of GI secretions and swallowed air.
Obstruction is present if the small-bowel loop is greater than 2.5 cm in diameter dilated proximal to a distinct transition zone of collapsed bowel less than 1 cm in diameter.
Acute postoperative obstruction: This is difficult to diagnose because symptoms often are attributed to incisional pain and postoperative ileus.

 Bowel Obstruction Overview
Bowel obstruction happens when stool is mechanically or functionally blocked from progressing down the digestive tract.
Bowel obstruction can also cause blood supply to the bowel to become completely or almost completely stopped, thus causing tissue damage and even tissue death.
In cases of volvulus or twisted bowel and intussusception, this procedure may be able to undo the blockage.

 Gynecologic surgery and subsequent bowel obstruction
Mechanical obstruction is a term usually applied when there is an actual physical barrier blocking the intestinal lumen, such as bands of adhesion, strangulated hernias, and pressure from pelvic tumors.
The duration of quiet intervals between bursts of peristalsis may suggest the level of obstruction; in high obstruction the time may be 3 to 5 minutes, whereas in low obstruction it may be 10 to 15 minutes.1 Palpation in the early stage of the disease may disclose no tenderness.
Treatment of large bowel obstruction is primarily surgical, and decompression of a severely distended colon is achieved by performance of a proximal temporary colostomy, often of the transverse colon.

 Constipation, impaction, and bowel obstruction
A normal bowel pattern is considered to be at least three stools per week and no more than 3 per day; however, these criteria may be inappropriate for cancer patients.[1,2] Constipation should be viewed as a subjective symptom involving the complaints of decreased frequency with incomplete passage of dry, hard stool.
Eighty percent of bowel obstructions occur in the small intestine; the other 20% occur in the colon.[2] Bowel obstructions are frequently seen in the ileum.
The most frequent causes of inoperability are extensive tumor and multiple partial obstructions.[5-7] A retrospective review evaluating surgical palliation of malignant bowel obstruction secondary to peritoneal carcinomatosis in 63 patients with nongynecological cancer used the ability to tolerate solid food at hospital discharge as the criterion for successful palliation.
