Identifying the Effect of Somatostatin Treatment in Early Postoperative Simple Small Bowel Obstruction

Primary Objective: To demonstrate whether an early fixed Somatostatin treatment improves the complete recovery rate of early postoperative simple small bowel obstruction (EPSSBO) compared with the common daily practice Notes: 1. complete recovery= toleration of solid food+ flatus+ passage+ recovery of bowel movement. 2. common daily practice includes: * NPO (Nil per mouth), re-dehydration, TPN (Total Parenteral Nutrition) if needed. Check \& make sure stability of electrolytes daily. * GI (Gastro-Intestinal) depression via NGT (Naso-Gastric Tube) * Discontinue opiates, instead of NSAIDs. (Non-Steroidal Anti-Inflammatory Drugs) * Pro-dynamic drugs or other drugs which may interfere with GI (Gastro-Intestinal) movement eg. anti-histamines, anti-cholinergic, opiates, anti-depressives are not indicated. Secondary Objectives: To investigate whether an early fixed Somatostatin treatment will bring much benefit to EPSSBO pts compared with the common daily practice,for this purpose,the study will investigate the endpoints below.
