1 A 34 year old woman with Vomiting and abdominal pain

2 The patient was a 34 y/o woman admitted because of epigastric pain developed from 2 months ago. It was a crampy pain without radiation that became better with vomiting. She didn t have any history of hematemesis, melena, jaundice, weight loss, headache and fever. No history of constipation, diarrhea and obstipation.

8 2 months ago was admitted for the first time at ER because of the same complaint. Some work up such as lab tests and abdominopelvic sonography was performed that were normal and she was discharged.

9 1 month ago because of abdominal pain, vomiting and rise in Cr was admitted in nephrology ward for rule out of the cause of ARF.

29 Small bowel obstruction (SBO) occurs when the normal flow of intestinal contents is interrupted. The most frequent causes are postoperative adhesions and hernias, which cause extrinsic compression of the intestine. Less frequently, tumors or strictures of the small bowel can cause intrinsic blockage.

30 The most common symptoms of SBO are abdominal distention, vomiting, crampy abdominal pain, and inability to pass flatus. In proximal obstruction, nausea and vomiting can be relatively severe compared to distal obstruction, but distention of the abdomen is somewhat less since the proximal intestine acts as a reservoir as it dilates.

31 Adhesions Postoperative adhesions cause the majority of small bowel obstructions. Malignancy Malignant tumors are the second most common cause of SBO. Hernias the third leading cause of intestinal obstruction. Strictures Intraluminal stricture can be caused by a number of disorders including Crohn's disease, certain drugs such as entericcoated potassium chloride solutions and NSAIDs, radiation therapy, ischemia, and tumors.

32 Trauma Traumatic small bowel obstruction caused by intramural hematoma results in nausea, vomiting, and upper abdominal tenderness. Intussusception is rare in adults Gallstone ileus results from erosion and fistulization between the biliary and intestinal tracts. Bezoars Superior mesenteric artery syndrome The syndrome is characterized by compression of the third portion of the duodenum due to narrowing of the space between the superior mesenteric artery and aorta and is primarily attributed to loss of the intervening mesenteric fat pad.

33 The diagnosis of SBO can be made by history and physical examination in the majority of patients. While imaging is potentially helpful in establishing the diagnosis, in most cases a laparotomy will be needed to make a definitive diagnosis and for treatment if a patient does not respond to nonoperative management. Laboratory studies are generally not helpful in determining the presence of small bowel obstruction, but can help in the assessment of the degree of dehydration.

34 Plain abdominal radiography Multiple air-fluid levels with distended loops of small bowel. Small bowel series These studies are highly sensitive and are the gold standard for determining whether an obstruction is partial or complete. Computerized tomography More recently, CT has been replacing the small bowel series as the adjunctive study of choice since it can simultaneously provide information about the presence, level, severity, and cause of obstruction. Ultrasonography ultrasound may be appropriate for pregnant patients or as a bedside test for the critically ill.

35 INITIAL MANAGEMENT The primary goals in the initial management of patients with SBO are to determine: The degree of volume depletion and metabolic derangement. The severity, cause, extent and location of the obstruction. Whether nonoperative management can be considered The need for and timing of operative intervention

36 NONOPERATIVE MANAGEMENT can sometimes be successful in patients with partial SBO. IV fluid Nasogastric tube Water soluble contrast- Hypertonic water soluble contrast agents (eg, Gastrografin) can be used for both diagnostic and therapeutic purposes in the setting of partial small bowel obstruction.

37 OPERATIVE MANAGEMENT Approximately one-quarter of patients admitted for small bowel obstruction will require operation. Patients suspected of having complete or closed-loop obstruction with fever, leukocytosis, tachycardia, metabolic acidosis, continuous pain or peritonitis warrant prompt exploration.

38 Surgery consult was done and the patient referred for laparatomy.

39 Laparatomy was performed: A nodule and stricture was found in 30cm from treits ligament in jejunum that was resected.
