A Rare Cause of Acute Abdomen in Children: Spontaneous Rupture of Choledochal Cyst Causing Peritonitis

Spontaneous rupture of the common bile duct cyst is a rare cause of acute abdomen in children. In our case, we present a 3-year-old patient with no history of trauma, whose diagnosis was confirmed by laparotomy, with a possible suspected common bile duct cyst due to massive ascites and a cystic lesion in the portal area. Although common bile duct cysts are mostly asymptomatic, various studies have shown that malignant transformation can cause important complications such as pancreatitis.Numerous causes have been suggested in the etiopathogenesis of rupture, such as parietal necrosis associated with pancreatic reflux irritation.Since rupture of cysts may require urgent laparotomy such as biliary peritonitis, it is important to know imaging findings that may be warning for early diagnosis. Because of the increased risk of cholangiocarcinoma after cyst excision, cholecystectomy and Roux-en-Y hepaticojejunostomy are the most common treatment procedures.

Clinical Features and Surgical Management of Bile Duct Cyst in Adults

Objectives. Bile duct cyst (BDC) is a rare congenital biliary malformation with 20% of cases initially diagnosed during adulthood. Although the incidence of BDC in adults is increasing worldwide, the clinical features of adult BDC remain unclear. The present study was aimed at characterizing the demographic and clinical features of this rare disease.Methods. We constructed a retrospective database and analyzed records of 106 patients (mean age,41.0±14.8 years; 18 men (17.0%)) with BDC treated at our institution from May 2012 to October 2018. Data collected included demographic characteristics, clinical manifestations, surgical patterns, and prognoses. We compared the characteristics of patients undergoing their primary BDC resection against those of patients undergoing reoperation. Risk factors for bile duct infection (BDI), a common complication of BDC, were identified using univariate and multivariate analyses.Results. Abdominal pain was the most common preoperative symptom, but 12 patients (11.3%) were asymptomatic. Ninety-nine patients underwent their primary BDC resection, and 7 patients received reoperation at our hospital. There was no significant difference in the postoperative complication rate between the two groups. Ninety-four patients were followed up for37.8±23.8 months, and BDI occurred in 33 patients (35.1%). Hilar anastomosis was an independent risk factor for BDI (odds ratio=3.561;95%confidence interval=1.101,11.517; andp=0.034).Conclusion. BDC was more frequent in women and abdominal pain was the most common preoperative symptom. The primary reason for reoperation was anastomotic stenosis. Reoperation had similar outcomes to primary resection and may be considered safe and acceptable if performed by a skillful surgeon. BDI was the most frequent postoperative complication with hilar anastomosis being the only independent risk factor. This highlights the importance of proper bile duct flow for surgical outcomes of BDC.

OUTCOME OF THE LAPAROSCOPIC CHOLEDOCHAL CYST EXCISION

Objectives: To study the clinical and subclinical characteristics, and the treatment results of the laparoscopic choledochal cyst excision. Subjects and Methods: patients with bile duct cyst were diagnosed and treated by laparoscopic excision at the Hue Central Hospital from 6/2013 to 9/2017. Result: The common bile duct cyst was type I with highest ratio (90.77%), in which type Ic occupied the rate was 53.84%. The most common clinical manifestation was abdominal pain which occupied 87.69% of cases. The average time of opreation was 197.58 ± 46.57. Drain pipe was removed within 1-4 days after surgery. The average time of postoperative treatment was 8.7 ± 3.8 days. The rate of early complications after surgery was 3.07%. The rate of postoperative complications was 1.54%. Conclusion: Laparoscopic treatment of choledochal cyst is safe, feasible and efficient in medical high-tech center Key words: laparoscopic, bile duct cyst
