CT diagnosis of afferent loop syndrome.

OBJECTIVE: To report the computed tomography (CT) features of afferent loop syndrome which is often clinically unsuspected. MATERIALS AND METHODS: The CT studies of five patients with afferent loop syndrome were reviewed. These patients had undergone gastroenterostomy and other surgical procedures, for malignant neoplasms in four and for peptic ulcer in one. Patients presented between 4 months and 15 years (average 5.5 years) after surgery. Symptoms were acute in all patients, the most common symptom being abdominal pain. In addition three of the patients had chronic symptoms including recurrent episodes of abdominal pain, recurrent ascending cholangitis, jaundice and bilious vomiting. RESULTS: The obstructed afferent loop appeared on CT as a fluid-filled tubular mass with an average diameter of 5.3cm. Valvulae conniventes were identified in all, and small intraluminal air bubbles in four. The dilated afferent loop was opacified with oral contrast material in only one patient. The loop was located in the subhepatic area in three patients and crossed the midline between the aorta and the superior mesenteric vessels in the other two. Additional findings included biliary dilatation in all five patients and signs of pancreatitis in one. Treatment was surgical in four patients (delayed for four months in one) and conservative in one. CONCLUSION: A fluid-filled tubular structure containing small air bubbles in the right upper quadrant or crossing the midline on CT in symptomatic patients after gastroenterostomy is characteristic of a dilated, possibly obstructed, afferent loop. The diagnosis is often not suspected clinically since patients may present many years after the initial surgery. Recognition of the characteristic CT findings will avoid both inappropriate procedures such as aspiration or drainage of an obstructed afferent loop and delay in treatment.

[Surgical treatment of afferent loop syndrome].

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.

[The chronic afferent loop syndrome (author's transl)].

Between 1968 and 1973, 12 patients with a chronic afferent loop syndrome were treated at the University Surgical Hospital in Munich (6 from own hospital and 6 B II resected patients from external hospitals). 11 of them had to undergo reoperation (1 patient refused). X-ray and gastroscopy confirmed the diagnosis of chronic afferent loop syndrome type I in all 12 cases. The obstruction was caused by: adhesion and kinking of the loop (7 cases), too long and mobile loops (6 cases) incorrect anastomosis (3 cases), torsion and stenosis in the mesocolonic slit (2 cases), internal hernia (1 case). 8 patients showed good operative results, in 2 patients symptoms still persist; 1 patient died of sepsis postoperatively.

Afferent loop syndrome: sonographic findings in seven cases.

We studied the sonographic findings in seven patients in whom afferent loop obstruction was first detected by sonography. All seven subsequently were proved at surgery to have afferent loop syndrome. The causes of the obstruction included internal hernia (n = 3), cancer recurrence (n = 2), marginal ulcer (n = 1), and development of cancer at the anastomosis site (n = 1). In all cases, the dilated afferent loop was seen on sonography as a tubular structure in the upper abdomen crossing transversely over the midline. The distal end of the afferent loop could be traced toward the anastomosis. The probable cause of the syndrome was predicted on the basis of sonography in two of three patients with cancer at the anastomosis. Our experience suggests that afferent loop syndrome can be diagnosed sonographically on the basis of the detection, location, and shape of the dilated afferent loop.

Biliary stone causing afferent loop syndrome and pancreatitis.

We report the case of an 84-year-old female who had a partial gastrectomy with Billroth-II anastomosis 24 years ago for a benign peptic ulcer who now presented an acute pancreatitis secondary to an afferent loop syndrome. The syndrome was caused by a gallstone that migrated through a cholecystoenteric fistula. This is the first description in the literature of a biliary stone causing afferent loop syndrome.

Palliative percutaneous tube enterostomy in afferent-loop syndrome presenting as jaundice: clinical effectiveness.

The purpose of this study was to investigate the clinical effectiveness of percutaneous tube enterostomy in afferent loop syndrome presenting as jaundice. Tube enterostomy was successfully performed in seven patients without procedural complications. The serum bilirubin level normalized in five patients but remained elevated in the other two, presumably related to more proximal bile duct obstruction. Percutaneous tube enterostomy is an effective palliative treatment in afferent loop syndrome presenting as an obstructing jaundice. However, coexisting biliary obstruction might be problematic for relieving jaundice with tube enterostomy.
