Colonic gallstone ileus treated by a transanal ileus tube followed by spontaneous gallstone dislodgement: A case report.

A 71-year-old obese woman was referred to our hospital with lower left abdominal pain. Computed tomography showed a 46 mm elliptic calcification lodged in the sigmoid-descending colon junction (SDJ), which had been detected 5 years prior but was not within the gall bladder at presentation. Therefore, we diagnosed colonic gallstone ileus with obstructive colitis caused by a gallstone. Colonoscopy revealed a smooth gallstone impacted at the sigmoid-descending colon junction, which was not fixed and could be pushed proximally with the endoscope. Dislodgement of the stone was unsuccessful with both a large polypectomy snare and a retrieval basket. Considering the high risk of surgery, we chose a non-surgical treatment strategy for obstructive colitis. Accordingly, a transanal ileus tube was placed to drain the proximal portion of the gallstone. The drainage of the colon by the ileus tube was satisfactory; the proximal colon was decompressed, ameliorating the obstructive colitis. Five days after tube placement, a colonoscopy revealed spontaneous passage of the gallstone into the rectum where it was finally removed. Cholecystocolonic fistula formation was confirmed by magnetic resonance imaging. We decided to surgically close the cholecystocolonic fistula to prevent future retrograde biliary infections. The surgery used a surgical stapler and was successful, with an uneventful postoperative course. Since radical surgical treatment of colonic gallstones and cholecystoenteric fistulas has a risk of postoperative morbidity and mortality, this case illustrates the importance of thoroughly considering nonsurgical interventions and surgeries for the safe treatment of colonic gallstone ileus.

Protein-losing gastroenteropathy complicated with asymptomatic primary biliary cholangitis, refractory to immunosuppressant, and improved by Helicobacter pylori eradication: a case report.

BACKGROUND: Protein-losing gastroenteropathy (PLGE) is a syndrome with a chief complaint of hypoalbuminemia, which occurs due to plasma protein leakage in the gastrointestinal tract, leading to general edema, ascites, and pleural effusions. CASE PRESENTATION: A 71-year-old woman visited another hospital for evaluation of hypoalbuminemia and systemic edema. She was hospitalized for a close inspection of hypoalbuminemia and was diagnosed with PLGE. Steroid and azathioprine therapy was prescribed; however, hypoalbuminemia did not improve, and the patient's condition worsened due to anasarca. As hospitalization was prolonged, the patient was transferred to our hospital. She was infected with Helicobacter pylori, and we performed H. pylori eradication. Following H. pylori eradication, her edema improved remarkably. CONCLUSION: We present the first case wherein H. pylori eradication successfully improved protein leakage in the lower gastrointestinal tract in a patient diagnosed with PLGE complicated with refractory to immunosuppressant treatment. H. pylori eradication should be considered in patients with PLGE complicated with H. pylori infection, without specific endoscopic finding or refractory to immunosuppressants.

Pneumatosis cystoides intestinalis induced by the α-glucosidase inhibitor miglitol.

Pneumatosis cystoides intestinalis (PCI) is a rare condition in which pneumocysts develop in the submucosa or subserosa of the colon. We report herein a case of PCI induced by the alpha-glucosidase inhibitor (alphaGI) miglitol. There have been 9 recorded cases of PCI induced by other alphaGIs, but this is the first report of miglitol causing PCI. The PCI lesions in our case were smaller than those induced by voglibose or acarbose. The possibility of PCI should be considered in diabetic patients on alphaGI therapy who complain of gastrointestinal symptoms, and the gastrointestinal tract should be thoroughly investigated in these patients.

Sclerotherapy for gastric fundal variceal bleeding: is complete obliteration possible without cyanoacrylate?

BACKGROUND: Many studies have suggested that endoscopic obliteration using cyanoacrylate for bleeding gastric fundal varices is effective. However, serious complications by injection of cyanoacrylate into varices have also been reported. METHODS: Thirty patients with bleeding gastric fundal varices underwent endoscopic injection sclerotherapy using 5% ethanolamine oleate under fluoroscopic guidance plus infusion of vasopressin and a transdermal nitroglycerin patch. The injection of 5% ethanolamine oleate was continued until it filled the varices and their feeder veins under fluoroscopic guidance. The injection needle was removed while thrombin glue was sprayed at the puncture site through the side hole of the injector needle to prevent bleeding from the puncture site. RESULTS: Complete hemostasis was achieved in 28/30 patients (93.3%). The cumulative rebleeding rate after 1, 3 and 5 years was 13%, 19% and 19%, respectively. The 1-, 3-, and 5-year cumulative mortality rates were 31%, 54% and 59%, respectively. There was no complication related to infusion of vasopressin and sclerotherapy procedure. CONCLUSION: The sclerotherapy method carried out using 5% ethanolamine oleate combined with infusion of vasopressin under fluoroscopic guidance might be a feasible method for obliteration of gastric fundal varices as an alternative to cyanoacrylate.
