Included is a case study of the afferent loop syndrome after subtotal gastric resection for a peptic ulcer. A 60 year old woman was successfully treated by the ligature of the afferent loop with the anastomosis between efferent loop and the duodenum. By means of this modification the following aims were achieved: 1 elimination of the antiperistaltic function of the afferent loop anastomosed "from the left", 2-replacement of resected stomach by means of anastomosis between the efferent loop and the duodenum.
We reviewed the sonographic findings in four patients with afferent loop obstruction from tumor of the gastric stump. All had undergone partial gastrectomy with Billroth type II gastrojejunostomy. The obstructed afferent loop was visible in all cases as a distended fluid-filled segment with multi-layered wall and few mucosal folds. Its course could be traced from the region of the hepatic hilum to the gastric stump. In two patients, the relationships between the loop and the mesenteric vessels, aorta and inferior vena cava allowed us to recognize it as postoperative duodenum. Thickening of the gastric remnant and obstructive jaundice were diagnosed in three cases. Since sonography is often used as the first imaging method in patients with abdominal complaints, knowledge about postsurgical appearance of the gastrointestinal tract is very important in detecting such pathological conditions.
