Unusual variant of choledochal cyst in a child: A case report, in Tertiary Specialized Hospital, Ethiopia

Comparison of open and laparoscopic outcomes of adult Type-I congenital choledochal cysts

Objective

To compare open and laparoscopic outcomes of adult Type-I congenital choledochal cysts.

Methods

Clinical data of 78 adult patients with Type-I congenital choledochal cysts, who had undergone cyst resection and Roux-en-Y hepaticojejunostomy in Chenzhou First People's Hospital from September 1, 2021 to August 31, 2022, were retrospectively analyzed. Patients who received open approach and Roux-en-Y hepaticojejunostomy constituted the open group (n=35,) and patients who received laparoscopic approach and Roux-en-Y hepaticojejunostomy were assigned into the laparoscopic group (n=43,). The intraoperative and postoperative conditions, relevant laboratory indicators, and the rate of complications were compared between the two groups.

Results

Intraoperative blood loss, postoperative time to first flatus, diet recovery time, time to drainage tube removal, and length of hospitalization of the laparoscopic group were lower in the laparoscopic group compared to the open group (P<0.05). One day after the operation, serum amylase (SAMY) levels in both groups were significantly lower, while the levels of total bilirubin(TBIL), alanine aminotransferase(ALT), and C-reactive protein(CRP) were higher than before the operation. Postoperative SAMY level in the laparoscopic group was significantly higher, while the postoperative TBIL and CRP levels were significantly lower than those in the open group (P<0.05). The incidence of postoperative complications in the laparoscopy group (4.65%) was significantly lower than the open group (20.00%) (P<0.05).

Conclusions

Laparoscopic cyst resection combined with Roux-en-Y hepaticojejunostomy is associated with lower extent of trauma, faster recovery, less inflammation, and fewer complications than open surgery in adult patients with Type-I congenital choledochal cysts.

Case Report: A rare case of choledochal cyst

Background: Choledochal cysts are dilated portions of the biliary tract that account for 1% of all benign biliary diseases. It is prevalent among Asian and female populations and the incidence is 1:100,000-150,000. Among the different types, only 15-35% of all choledochal cysts are type IV cysts, with type I being the most common representing 50-80%. Clinical presentation and therapy of biliary cysts (BC) differ depending on the type. Case: We present a case of a 2-year-old male who presented with non-specific symptoms of multiple episodes of vomiting. Laboratory investigations revealed raised alkaline phosphatase and gamma-glutamyl transpeptidase. His symptoms of acute pancreatitis were resolved with conventional therapy. Ultrasonography of the abdomen showed intra and extra-hepatic cystic biliary tree dilatation suggestive of choledochal cyst Type IV A. Conclusions: Choledochal cysts present with clinical features varying with age and anatomical variants and can pose challenges in management that can be addressed by surgery to avoid further complications.
