In early small bowel obstruction, 1,500 mLoffluid accumulates in the bowel. of the bowel loops to the viscera and the parieties in the area of inflammation. Following obstruction fluids accumulates in the bowel wall and any excess fluid is secreted in the lumen. 1996). We reviewed the imaging findings of 150 cases in whom small bowel obstruction was clinically suspected and confirmed at surgery. Rectal examination Sequestration of fluid oral to the obstruction quickly leads to distension of the intestine that can be identified by rectal palpation (Kopt 1987; White 1990) or transabdominal ultrasound (Klohnen et al. Obstruction of a large vein, such as the portal vein, can lead to ascites and fluid sequestration that may be difficult to manage. By definition, intestinal obstruction implies the failure of ingesta or intestinal secretions to move in a normal aboral direction [1]. Neonates with gastroschisis have fluid losses that are at least 3-4 times that of a healthy newborn from insensible losses, heat, and fluid losses from the exposed bowel, and third spacing of fluid from sequestration of intestinal fluid. When intestinal contents cannot pass normally, the bowel proximal to the site of obstruction becomes dilated, while contents distally are able to pass.

Aim of our report is to demonstrate the value of free fluid detected by US in differentiating between low and high-grade small bowel obstruction. Large bowel obstruction is a disease entity frequently encountered by the general surgeon The choice of operation, particularly for malignant left-sided obstructions remains controversial A single-stage operation with primary resection and anastomosis can be performed in many patients with obstructive colonic cancers; The most useful initial investigation is a plain supine abdominal X-ray (see Figs 19.2 to 19.4).

At surgery etiology of small bowel obstructions was various, but most of cases related to adhesions (70 cases). The most important cause of extracellular fluid depletion in terms of frequency is loss of gastrointestinal secretions through either diarrhea or vomiting. The blockage would be a complete obstruction, not even allowing liquid waste to pass, therefore causing a sequestration of fluid. Third-space sequestration is seen when abnormal collections of fluid develop in spaces where they cannot be reabsorbed into the intravascular space. Although the features of acute bowel obstruction are usually clinically obvious, the presentation of subacute small bowel obstruction and acute on chronic (large) bowel obstruction may be much more subtle, Consider bowel obstruction whenever a patient presents with colicky abdominal pain and recurrent vomiting (especially if prolonged for more than 24 hours), particularly if diarrhoea is minimal or absent, Abdominal distension is an important sign with bowel obstruction, but it may be absent if the obstruction is high and may be difficult to detect in obese patients.

An obstruc-tion typically leads to localized edema; fluid and plasma proteins accumulate and can't be drained into the general circulation because of the lymphatic obstruction (see The role of the lymph system).

Sequestration of fluid into a third-space also can lead to volume loss and hypovolemic shock. Bowel sounds may be scanty or absent if the obstruction is longstanding and the small bowel has become inactive Copious vomiting or sequestration of fluids in the intestinal lumen prevents their reabsorption and produces severe fluid and electrolyte disturbances. low colonic obstruction does not commonly give rise to small bowel fluid levels unless advanced.
