Surgical treatment for afferent loop syndrome (ALS) in patients with recurrent gastric cancer is usually not feasible because of the recurrent tumor mass at the anastomosis site and/or extensive carcinomatosis resulting in bowel loop fixation. Furthermore, ALS usually makes oral intake impossible, resulting in a rapid deterioration in general condition. In this situation, gastroscopic stenting at the anastomotic site and/or percutaneous external drainage may be a more feasible alternative for palliation. We herein report a recurrent gastric cancer whose ALS was successfully treated with internal and external drainage procedures.

Stent insertion is an effective method for treating a patient with gastric outlet obstruction that's caused by recurred cancer at the anastomosis site. There are some complications associated with stent insertion, such as perforation, bleeding, ulceration and obstruction. There are only rare Korean case reports of afferent loop syndrome after stent insertion. We report here on a case of afferent loop syndrome that occurred after insertion of a double-layered pyloric stent for gastric outlet obstruction in a patient with stump gastric cancer after undergoing Billroth II radical subtotal gastrectomy.

Afferent loop syndrome is a rare complication of gastrojejunostomy. Patients usually present with abdominal distention and bilious avomiting. Afferent loop syndrome in patients who have undergone a pylorus preserving pancreaticoduodenectomy can present with ascending cholangitis. This condition is related to a large volume of reflux through the biliary-enteric anastomosis and static materials with bacterial overgrowth in the afferent loop. Patients with afferent loop syndrome after pylorus preserving pancreaticoduodenectomy frequently cannot be confirmed as surgical candidates due to poor medical condition. In that situation, a non-surgical palliation should be considered. Herein, we report two patients with afferent loop syndrome presenting with obstructive jaundice and ascending cholangitis. The patients suffered from the recurrence of pancreatic cancer after pylorus preserving pancreaticoduodenectomy. The diagnosis of afferent loop syndrome was confirmed, and the patients were successfully treated by inserting an endoscopic metal stent using a colonoscopic endoscope.

Afferent loop syndrome (ALS) is a rare cause of recurrent pancreatitis. Recurrent pancreatitis in association with ALS can develop due to impaired outflow of pancreatic juice or reflux of enteric secretions caused by increased intraluminal duodenal pressure. Here, we report a case of ALS presenting as recurrent acute pancreatitis due to chronic intermittent partial obstruction of the third portion of the duodenum caused by postoperative adhesion. Interestingly, pancreatic histology showed a granulocytic epithelial lesion, which is a diagnostic feature of type 2 autoimmune pancreatitis (AIP, idiopathic duct centric chronic pancreatitis [IDCP]). From this case we learned that the diagnosis of type 2 AIP should be made in the appropriate clinical setting.

Afferent loop syndrome caused by an impacted enterolith is very rare, and endoscopic removal of the enterolith may be difficult if a stricture is present or the normal anatomy has been altered. Electrohydraulic lithotripsy is commonly used for endoscopic fragmentation of biliary and pancreatic duct stones. A 64-year-old man who had undergone subtotal gastrectomy and gastrojejunostomy presented with acute, severe abdominal pain for a duration of 2 hours. Initially, he was diagnosed with acute pancreatitis because of an elevated amylase level and pain, but was finally diagnosed with acute afferent loop syndrome when an impacted enterolith was identified by computed tomography. We successfully removed the enterolith using direct electrohydraulic lithotripsy conducted using a transparent cap-fitted endoscope without complications. We found that this procedure was therapeutically beneficial.

Afferent loop syndrome(ALS) is caused by obstruction of the afferent loop after subtotal gastrectomy with Billroth II gastrojejunostomy. Prompt diagnosis of ALS is important as perforation of the loop occurs. The aim of this study is to ascertain the value of sonography and CT to diagnose ALS. We describe the radiologic findings in ten patients with ALS. The causes of ALS, established at surgery, included cancer recurrence (n=4), internal hernia(n=4), marginal ulcer (n=1), and development of cancer at the anastomosis site(n=1). Abdominal X-ray and sonography were performed in all cases, upper GI series in five cases and computed tomography in two cases. The dilated afferent loop was detected in only two cases out of ten patients in retrospective review of abdominal X-ray. ALS with recurrence of cancer was diagnosed in three cases by upper GI series. Of the cases that had sonography, the afferent loop was seen in the upper abdomen crossing transversely over the midline in all ten patients. The causes of ALS were predicted on the basis of the sonograms in three of the five cancer patients. In two cases of computed tomography, the dilated afferent loop and recurrent cancer at the remnant stomach were seen. Our experience suggests that the diagnosis of afferent loop syndrome can be made on the basis of the typical anatomic location and shape of the dilated bowel loop in both sonography and computed tomography.

Afferent loop syndrome is a rare complication of pancreaticoduodenectomy, and the endoscopic approach is difficult due to the surgically altered anatomy. Herein, we report a case of afferent loop obstruction treated by endoscopic metal stent insertion using two endoscopes. A 57-year-old male who had undergone the Whipple operation 7 months prior for pancreatic head cancer presented with abdominal pain and jaundice. Abdominal computed tomography showed afferent loop obstruction due to recurrent metastatic pancreatic cancer. First, we attempted to insert the stent using percutaneous transhepatic approaches following percutaneous transhepatic biliary drainage, but these failed. We therefore accessed the obstruction site using a relatively thin endoscope and then exchanged this endoscope for another with a large working channel, through which the self-expandable metal stent was passed. The stent was inserted successfully. This method will increase the success rate of endoscopic treatment.
