Timing of Kasai Procedure for Biliary Atresia: An Analysis of the Pediatric National Surgical Quality Improvement Program Database.

INTRODUCTION: Biliary atresia is a rare liver disease of unknown etiology affecting approximately 1 in 10,000 children. This disease initially presents as inflammatory obstruction of bile ducts leading to cholestasis and eventually fibrosis of hepatic tissue. Affected patients are ideally treated early with portoenterostomy (Kasai procedure) as age at surgery is an important prognostic factor for native liver survival and need for liver transplant. This study aimed to evaluate the age at which patients in the United States are receiving this procedure. METHODS: The American College of Surgeons National Surgical Quality Improvement Program Pediatric database was used to identify patients between 2012 and 2021 who underwent a primary procedure of portoenterostomy. The age at time of surgery and perioperative analysis was performed. The data underwent simple descriptive statistics. RESULTS: Eight hundred twenty four patients were identified who underwent Kasai procedure. Four hundred seventy four (58.2%) were female with the predominant race being White (49.5%). The median age at surgery was 57 d old (interquartile range 41-71). Readmission and reoperation rates within 30 d were 30% and 15.2%, respectively. There were no deaths within 30 d. CONCLUSIONS: Within the National Surgical Quality Improvement Program database, the median age of pediatric patients undergoing Kasai procedure for biliary atresia in the United States exceeds the goal of 45 d. Further studies are needed to investigate factors that may affect time to diagnosis and time to Kasai procedure.

Acute cholecystitis, obesity, and steatohepatitis constitute the lethal triad for bile duct injury (BDI) during laparoscopic cholecystectomy.

OBJECTIVE: The most feared complication during laparoscopic cholecystectomy remains a bile duct injury (BDI). Accurately risk-stratifying patients for a BDI remains difficult and imprecise. This study evaluated if the lethal triad of acute cholecystitis, obesity, and steatohepatitis is a prognostic measure for BDI. METHODS: A retrospective review of the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) registry was performed. All laparoscopic cholecystectomy cases within the main NSQIP database for 2012-2019 were queried. Two study cohorts were constructed. One with the lethal triad of acute cholecystitis, BMI ≥ 30, and steatohepatitis. The other cohort did not have the full triad present. Multivariate analysis was performed via logistic regression modeling with calculation of odds ratios (OR) to identify independent factors for BDI. An uncontrolled and controlled propensity score match analysis was performed. RESULTS: A total of 387,501 cases were analyzed. 36,887 cases contained the lethal triad, the remaining 350,614 cases did not have the full triad. 860 BDIs were identified resulting in an overall incidence rate 0.22%. There were 541 BDIs within the lethal triad group with 319 BDIs in the other cohort and an incidence rate of 1.49% vs 0.09% (P < 0.001). Multivariate analysis identified the lethal triad as an independent risk factor for a BDI by over 15-fold (OR 16.35, 95%CI 14.28-18.78, P < 0.0001) on the uncontrolled analysis. For the controlled propensity score match there were 29,803 equivalent pairs identified between the cohorts. The BDI incidence rate remained significantly higher with lethal triad cases at 1.65% vs 0.04% (P < 0.001). The lethal triad was an even more significant independent risk factor for BDI on the controlled analysis (OR 40.13, 95%CI 7.05-356.59, P < 0.0001). CONCLUSIONS: The lethal triad of acute cholecystitis, obesity, and steatohepatitis significantly increases the risk of a BDI. This prognostic measure can help better counsel patients and potentially alter management.

Robotic Surgery for Pediatric Choledochal Cysts: An American Case Series and Literature Review.

INTRODUCTION: Choledochal cysts are rare congenital biliary cystic dilations. The US incidence rate varies between 5 and 15 cases per 1,000,000 people. In contrast, Asians, which are a large subset of the population of Hawaii, have an incidence of approximately one in every 1000 births. We report our experience with robot-assisted laparoscopic surgical management with biliary reconstruction of choledochal cysts which to date is the largest American case series to be reported. MATERIALS AND METHODS: From 2006 to 2021, patients diagnosed with a choledochal cyst(s) at a tertiary children's hospital were retrospectively reviewed. Perioperative analysis was performed. Complications were defined as immediate, early, or late. The data underwent simple descriptive statistics. RESULTS: Nineteen patients underwent choledochal cystectomy and hepaticoduodenostomy. Thirteen underwent a robotic approach while the rest were planned laparoscopic. Eighteen of 19 were female with 15/19 of Asian descent. The ages ranged from 5 mo to 21 y. Presenting diagnoses included jaundice, primary abdominal pain, pancreatitis, and cholangitis. Sixty eight percent had type 1 fusiform cysts while the rest were type 4a. Operative time and length of stay for robotic versus laparoscopic were 321 versus 267 min and 8.2 versus 17.3 d, respectively. For the robotic group, there was one immediate complication due to peritonitis. One-year follow-up revealed two patients requiring endoscopic retrograde cholangiopancreatography with dilation/stenting for an anastomotic stricture. There were no anastomotic leaks. CONCLUSIONS: Robot-assisted laparoscopic choledochal cystectomy with hepaticoduodenostomy is associated with overall good outcomes with the most common long-term complication being anastomotic stenosis.
