Other tests may include a barium enema, CT scan, or X-ray.
In the history, some data are relevant to the risk of bowel obstruction. There may be many different types of obstructions in the intestines, including blockage from a foreign object, intussusception, strangulation, and paralytic ileus. Hartmann’s procedure should be the preferred choice in the patients with impaired blood supply of intestinal wall and high surgical risk compared to loop colostomy. Small intestine. The neoplastic obstruction of distal colon or rectum shows great distension of the colon above the obstacle and chronic and progressive symptoms of constipation with the change of regular bowel function toward constipated bowel function, changes of stool caliber, long-term cathartic use. The cecum is more dilated colonic section. Small or large bowel obstacle site. Our team is growing all the time, so we’re always on the lookout for smart people who want to help us reshape the world of scientific publishing. Login to your personal dashboard for more detailed statistics on your publications. These can include: Sometimes there may be no actual obstruction, but the bowels behave as if they are obstructed. When this condition occurs, food cannot be properly passed through, resulting in obstruction. When there is an area of weak muscle in the abdomen, a portion of the small intestine can slip through the muscle fibers causing a hernia.
Surgical procedures are indicated for the treatment of severe and continuous symptomatology that can be related to a portion of the digestive tract or for complete failure of conservative therapy [73]. The less frequent in our experience were acute large bowel obstructions (28.8%). Intestinal obstruction (IO) is one of the most common diseases in abdominal surgery. In the obstructed patients, it is possible to hear some characteristic sounds by abdominal auscultation: runs of borborygmi, chorus of tinkling high pitched musical sounds at the same time of peristaltic waves, and colicky pain. The laboratory data should evaluate hypovolemia, initial renal failure, hemoconcentration, metabolic abnormalities (hyponatremia, hypokalemia), and leucocytosis. Moreover, the plain radiography is widely available and less expensive; its regular performance requires an upright position of patients; the lateral position is a makeshift solution. Even if you think there's no way they could have possibly swallowed something, you could absolutely be wrong. This band of tissue may eventually encircle the intestine, and squeeze it shut causing an obstruction. The intestinal resection has been performed in six cases (11.5%). Philadelphia, PA: Elsevier; 2017:chap 49. In the conservative option, the use of pharmacologic agents can be added to increase colonic motility. The evaluation should be made of inflammatory bowel disease (IBD) or other intestinal inflammation based on the previous diagnosis, therapy, and evolution of the disease. If the protruding hernia becomes pinched, it can cause intestinal obstruction. The ischemic evolution of this condition is preceded by intramural thrombosis veins and is completed with the necrosis that proceeds from the mucosa to the serosa. The ischemic necrosis of obstructed bowel should be caused by progressive thinning of gut wall, reduction of the lumen of vessels, and finally interruption of the blood supply [4]. There are several proposals: at the beginning resolution of the occlusive complication only with colostomy (two-stage procedure) followed, sometime later, by resection of neoplastic lesion (with radical surgical criteria or palliative).
Complications may include or may lead to: If the obstruction blocks the blood supply to the intestine, it may cause infection and tissue death (gangrene). Testing will often begin by listening to the intestines with a stethoscope. This problem most commonly occurs after surgery, or can be caused by spinal injury, drugs, or inflammation.

Consequently, it can develop damage of the blood flow in the parietal vessel earlier and more evident than in the small gut because the colon has the lowest blood flow across the abdominal viscera. On the other hand, in the first phase of obstructive syndrome, the patients with a “closed-loop obstruction” or intestinal hernias or small bowel volvulus with short intestinal segment, abdominal distension can be minimal. Some measures can be required: the use of a bladder catheter to monitoring urine output, adequate intravenous access, arterial canalization, and CVP monitoring. Philadelphia, PA: Elsevier; 2021:chap 123. Routine laboratory studies are not specific for a diagnosis of intestinal obstruction. The tumor site along the colon is an important factor for the therapeutic choice. I don't think he ever had an intestinal or bowel obstruction either. The presence of a hard lump or the particular kinds of sound produced, especially in a child, may help determine whether or not an obstruction exists. Obstruction may be mechanical, simple or strangulated, and paralytic. Beside the abdominal distension, the physical examination can point out hyperresonance, obstructive gut sounds, and visible peristalsis. This is when you have symptoms of a … CT scan can provide other diagnostic information: ascites, rotation of mesentery (whirl sign), mesenteric edema, bowel wall thickening >3 mm, submucosal edema-hemorrhage, venous cutoff sign by venous thrombosis, poor segmental bowel wall enhancement, pneumomatosis intestinalis, edematous mesentery, and hemorrhage in the mesentery. In fact, its use requires some selection criteria: proximal obstruction, localized distension on radiography, no sepsis, and mild abdominal distension [58–60]. The visible peristalsis can be seen in very thin patients. Indeed, the obstructive syndrome starts with the absence of flatus. The first objective should be the control and management of malignancy.
Then, in the first step of the diagnosis, the distinction of mechanical or paralytic obstruction is performed.
