Ascaris lumbricoides is a comman intestinal helminths in humans. It is a parasite which commonly affects society with a low socioeconomic status, especially in tropical and rural areas. Ascaris lumbricoides infestation can lead to serious complications because of the mobility of the worms. The parasite can cause a variety of complications like intestinal obstruction, perforation, biliary obstruction, pancreatitis, peritonitis, liver abscess, cholangiohepatitis, volvulus, and gangrene, etc. A 59-year-old female patient hospitalized with the diagnosis of mesenteric ischemia was operated on for jejunal resection. On the 6th postoperative day, a worm was noticed emerging through the nasogastric tube. Ascaris lumbricoides was determined as a result of the examination microbiology laboratory. The patient was treated successfully with one dose of albendazole 200 mg 1x2. Our case describes a clinical situation of ascariasis observed after jejunal resection and emphasizes the importance of remaining aware of this rare complication of ascariasis.

Advanced age is a strong predictor of high perioperative mortality in surgical patients and patients aged 75 years and older have an elevated surgical risk, much higher than that of younger patients. Progressive advances in surgical techniques now make it possible to treat high-risk surgical patients with minimally invasive procedures. Endovascular techniques have revolutionized the treatment of several vascular diseases, in particular carotid stenosis, aortic pathologies, and severely incapacitating intermittent claudication or critical limb ischemia. The main advantages of the endovascular approach are the low complication rate, high rate of technical success and a good clinical outcome. Biliary stenting has improved the clinical status of severely ill patients with bile duct stricture before major surgery, and represents a good palliative therapy in the case of malignant biliary obstruction.

BACKGROUND The aim of this study was to classify ischemia-type biliary lesions after liver transplantation according to their imaging findings and severity of clinical manifestations and to analyze the relationship between such classification and prognosis. MATERIAL AND METHODS We collected clinical data of patients with ischemia-type biliary lesions (ITBL) after liver transplantation in the Organ Transplantation Center, the First Central Hospital of Tianjin, from August 2012 to July 2013; all patients were classified according to their imaging findings and relevant clinical data to analyze the relationship between their classification and prognosis. RESULTS The mean postoperative survival time, as well as the 1-, 3-, and 5-year survival rate, in Group ITBL showed statistical significance when compared with those in Group NITBL (log rank=12.13, P<0.001), but the mean postoperative survival times among the mild, moderate, and severe ITBL cases showed no statistical significance. The incidence rates of 1-, 3-, and 5-year adverse prognosis in Group ITBL showed statistical significance when compared with Group NITBL with <2% patients who had anastomotic biliary obstruction (log rank=277.06, P<0.001), among which the difference in the incidence rate of adverse prognosis between severe and moderate ITBL cases showed no statistical significance. The difference in the incidence rate of adverse prognosis between mild and moderate ITBL cases showed statistical significance (log rank=6.01, P=0.014), and the difference in the incidence rate of adverse prognosis between mild and severe ITBL cases showed statistical significance (log rank=10.98, P=0.001). CONCLUSIONS ITBL classification based on the severity of biliary imaging and bilirubin level can predict the prognosis of ITBL.

Gallbladder volvulus is a rare condition with similar presentation to acute cholecystitis. It is caused by the gallbladder twisting upon its mesentery leading to potential ischemia and biliary obstruction. A 77-year-old female presented with symptoms of right upper quadrant pain and nausea. She was found to have an elevated leukocytosis and a palpable right upper quadrant abdominal mass on exam. Imaging revealed a severely distended gallbladder with pericholecystic fluid and wall thickening without gallstones. Intraoperatively, an extremely distended, ischemic gallbladder was noted to have twisted upon its mesentery. The structures were able to be identified and the gallbladder was able to be safely removed with a laparoscopic approach despite its large size. Gallbladder volvulus is important to consider in the differential of acute cholecystitis because delay in intervention could lead to gallbladder necrosis and possible perforation, increasing the patient's morbidity and mortality.

BACKGROUND Mirizzi syndrome is biliary obstruction caused by extrinsic compression of the distal common hepatic duct by a gallstone in the adjacent cystic duct or infundibulum of the gallbladder. Post-cholecystectomy Mirizzi syndrome (PCMS) is Mirizzi syndrome in the post-surgical absence of a gallbladder. This case report of PCMS and review of the literature illustrates the diagnostic and therapeutic challenges in evaluating and managing Mirizzi syndrome. CASE REPORT A 44-year-old female with a remote history of laparoscopic cholecystectomy presented to a community teaching hospital with acute and severe upper abdominal pain and tenderness. Laboratory data revealed markedly elevated transaminases of a magnitude most often observed with hepatitis from acute viral infection, ischemia, or exposure to a hepatotoxin. PCMS was ultimately diagnosed at endoscopic retrograde cholangiopancreatography after being misdiagnosed as choledocholithiasis on magnetic resonance cholangiopancreatography. After transfer to an academic quaternary care referral hospital, the patient's extrahepatic biliary tree was reportedly cleared of gallstones following endoscopically-directed shock-wave lithotripsy performed at repeat -endoscopic retrograde cholangiography. CONCLUSIONS Recognizing post-cholecystectomy syndrome, in general, and PCMS, in particular, is critical when caring for patients presenting with persistent or recurrent symptoms or signs of biliary obstruction following cholecystectomy. Expediently identifying and definitively relieving the biliary obstruction, while limiting the risk of iatrogenic complication, is the priority when caring for patients with PCMS.
