Multiple Biliary Stones: a Rare Long-term Complication after Whipple Procedure / Múltiplos cálculos biliares: uma complicação rara a longo prazo após o procedimento de Whipple

A hypertensive, diabetic woman underwent a successful Whipple procedure at the age of 84 due to carcinoma of the ampulla of Vater. She presented an extremely rare complication 24 months after the surgery, consisting of acute cholangitis due to multiple biliary lithiases associated with a bilioenteric anastomotic stricture. The diagnosis was confirmed with computed tomography, magnetic resonance cholangiopancreatography, and cholangiography. The patient was successfully treated with multiple percutaneous transhepatic cholangioplasties (AU)

Cardiac allograft vasculopathy after heart transplantation: summary of a single-center long-term follow-up experience in Fuwai Hospital / 器官移植

Objective To summarize the incidence of cardiac allograft vasculopathy (CAV) after heart transplantation and the effect on the long-term survival of recipients. Methods Clinical data of 1 006 heart transplant recipients were retrospectively analyzed. Of 48 CAV patients, 4 cases were not included in this analysis due to lack of imaging evidence. A total of 1 002 recipients were divided into the CAV group (n=44) and non-CAV group (n=958) according to the incidence of CAV. The incidence of CAV was summarized. Clinical data of all patients were statistically compared between two groups. Imaging diagnosis, coronary artery disease, drug treatment and complications, postoperative survival and causes of death of CAV patients were analyzed. Results Among 1 006 heart transplant recipients, 48 cases (4.77%) developed CAV. Compared with the non-CAV group, the proportion of preoperative smoking history, preoperative hypertension history, coronary artery disease and perioperative infection was significantly higher in the CAV group (all P < 0.05). Among 44 patients diagnosed with CAV by imaging examination, 24 cases were diagnosed with CAV by coronary CT angiography (CTA), 4 cases by coronary angiography (CAG), and 16 cases by coronary CTA combined with CAG. Among 44 patients, the proportion of grade Ⅰ CAV was 45% (20/44), 30% (13/44) for grade Ⅱ CAV and 25% (11/44) for grade Ⅲ CAV, respectively. All patients received long-term use of statins after operation, and 20 patients were given with antiplatelet drugs. Among 44 CAV patients, 11 patients underwent percutaneous coronary intervention, 6 cases received repeated heart transplantation, and 8 patients died. Kaplan-Meier survival analysis demonstrated that there was no significant difference in the long-term survival rate between the CAV and non-CAV groups (P > 0.05), whereas the survival rate of patients tended to decline after the diagnosis of CAV (at postoperative 6-7 years). The long-term survival rates of patients with grade Ⅰ, grade Ⅱ and grade Ⅲ CAV showed no significant difference (P > 0.05). Even for patients with grade Ⅰ CAV, the long-term survival rate tended to decline. Conclusions CAV is a common and intractable complication following heart transplantation, and the long-term survival rate of patients after the diagnosis of CAV tended to decline. Deepening understanding of CAV, prompt prevention, diagnosis and treatment should be delivered to improve the long-term survival rate of patients after heart transplantation.

Long-term Results of Roux-en-Y Procedure in Choledochal Cyst and in Cholelithiasis / 한국간담췌외과학회지

BACKGROUND/AIMS: The long-term results of Roux-en-Y procedure as a treatment for choledochal cyst or cholelithiasis were compared and analyzed. METHODS: A retrospective analysis was carried out for 70 patients (38 type 1 or type 4A choledochal cysts, 33 cholelithiasis) with ages ranging from 17 to 74 years who had undergone hepaticojejunostomy or choledochojejunostomy in a Roux-en-Y manner, with or without hepatectomy. RESULTS: Late complications related to the surgical procedure include cholangitis, recurrent stone, malignancy, abscess, and peptic ulcer disease. The late complication rate was 37.8% in the choledochal cyst group, and 27.3% in the cholelithiasis group. Cholangitis were found in 8.1% of the choledochal cyst group, and in 12.1% of the cholelithiasis group. Recurrent stones were found in 10.8% and 18.2%, respectively. A malignant tumor was found in each group, and both of them were not resectable. Peptic ulcers or erosions were found in 5 patients (13.5%) of the choledochal cyst group, but no one in the cholelithiasis group (p=0.056). CONCLUSION: Late complications after Roux-en-Y procedure in choledochal cyst or cholelithiasis are not uncommon and relatively serious. Long-term follow-up for the patients is mandatory, with attention being given to not only biliary symptoms, but also symptoms related to peptic ulcer disease.

A Case of Early Manifested Long-term Complications in MODY(Maturity Onset Diabetes in Young) Patient / 대한소아내분비학회지

A 14-year old boy presented with myoclonic seizure with rightward deviation of eyeballs. Three years ago, he was diagnosed as diabetes necessitating insulin injection. At that time, his blood glucose was 448mg/dl, HbA1c 27.8%, serum C-peptide rose from 0.4 to 1.1ng/ml after glucagon, and 24 hour urine C-peptide was 6.7microg/day. Eye examination was normal. His maternal grandmother died of diabetes at 50 years old, and his mother's sister and his elder sister had NIDDM with oral hypoglycemics. But, he didn't control hyperglycemia himself since that time. On physical exam, his grasping power was decreased in right hand, and cataract was detected at the posterior pole of lenses in both eyes requiring surgery. EEG showed partial seizure disorder in left frontoparietal area, and MRI revealed cerebral infarction in left frontoparietal cortex. Sensory-motor polyneuropathy was noted in nerve conduction velocity. His neurologic symptom was improved gradually with insulin therapy, but nerve conduction velocity and MRI abnormalities did not improved after 6 months of follow-up. Although long-term diabetic complication is common in poorly controlled diabetes, very early manifested eye and nervous system complications like this case is extremely uncommon.

Long-term efficacy of endoscopic papillosphincterotomy and the risk factors for complications / 西安交通大学学报(医学版)

Objective To evaluate the efficacy and safety of endoscopic sphincterotomy(EST)in treating common bile duct stone or strictive papillitis,and then analyze possible related risk factors for long-term complications after EST.Methods We made a retrospective study of 103 out of 158 patients who had EST from January 2005 to December 2006.Results In the 103 patients,there were 13 cases of long-term complications(≥3 m after EST),the incident rate being 12.6%:recurrent calculus of common bile duct in 8 cases,combined cholangitis in 6;cholangitis in 1;acute calculus cholecystitis in 2;residual calculus in 1 case;chronic pancreatitis in 1 case.Conclusion Endoscopic papillosphincterotomy is an effective and safe way to treat biliary tract obstruction.Preoperative jaundice may be the risk factor inducing long-term complications after EST.
