Closed Segment Obstruction Related To Tumor Obstruction On Both Ends

Mechanical intestinal obstructions are frequent clinical problems that the surgeons come across in their daily surgical practices. Although the closed segment obstruction is a rare type of the mechanical intestinal obstruction, it is all the more dangerous because of the rapid increase in distension and its entailing strangulation based on the upset circulation in the intestinal wall. In our study we have discussed two closed segment cases related to colon tumor existence along with literature on the subject. The first case is a 38-year-old female patient who underwent only loop ileostomy without a resection because of inoperable rectosigmoid corner tumor 10 months ago at another health center. The patient presented to our clinic with complaints of abdominalgia and distension.The patient was diagnosed with closed segment obstruction based on the infiltration of the cecum by the tumor in the rectosigmoid area. The patient was treated through opening up a colostomy from the transverse colon.The second case was a 50-year-old male patient. The patient, who had undergone left hemicolectomy because of sigmoid colon tumor three years before, presented to the emergency service with a condition of mechanical ileus.The patient was diagnosed with closed segment obstruction in the small intestine related to the metastatic masses in the small intestinal mesentery, intraoperatively. The patient was treated through subtotal small intestinal resection.Closed segment obstructions are rare causes of mechanical intestinal obstructions that need to be treated rapidly. Closed segment obstructions that develop because of the tumor infiltration on both ends are quite rare. Therefore, we aim at discussing the aforementioned cases of closed segment obstruction that developed because of tumor obstruction on both ends and surgically treated in our clinic, along with literature on the subject.
