A narrative review of the modern surgical management of pediatric choledochal cysts

The SHURUI single-port robotic system for choledochal cyst excision and biliary reconstruction in children: A case report (with video)

INTRODUCTION

Total cyst excision and Roux-en-Y hepaticojejunostomy is the standard procedure for treating congenital choledochal cysts, which requires high surgical skills. Our aim is to introduce the experience with the SHURUI single-port robotic system in pediatric surgery.

PRESENTATION OF CASE

In this study, we present a case demonstrating the application of the SHURUI single-port robotic system in performing choledochal cyst excision and Roux-en-Y hepaticojejunostomy in a pediatric patients. Roux-en-Y anastomosis was constructed extracorporeally, then choledochal cyst excision and hepaticojejunostomy was performed intracorporally using the SHURUI Surgical System. Surgical complications and the wound outcomes were assessed. The total duration of the operation was 292 min, comprising an extracorporeal time of 45 min, docking time of 19 min, and intracorporal time of 183 min. The estimated blood loss was minimal at only 2 mL. The patient was discharged 6 days post-operation, and exhibited satisfactory recovery at the one-month follow-up.

DISCUSSION

This case represents an initial experience with the SHURUI Surgical System in managing a pediatric choledochal cyst. The results indicate that the system is feasible and safe for this procedure, and may have some advantages over laparoscopic and open approaches.

CONCLUSION

The SHURUI Surgical System is both feasible and safe in pediatric surgery, and it may offer certain advantages over laparoscopic and open approaches.

Whole-Course Intraperitoneal Robot-Assisted Choledochal Cyst Excision with a Hidden Incision in Children Under 1 Year Old

Background: Whole-course intraperitoneal robot-assisted choledochal cyst resection in children under 1 year of age is controversial due to its technical challenges. Current Pfannenstiel incision is widely used in adults for its cosmetic effects but is rarely used in children. Materials and Methods: We conducted a prospective, single-center study to assess the feasibility, safety, and cosmesis of whole-course intraperitoneal robot-assisted choledochal cyst resection with Pfannenstiel incision in children under 1 year of age. Results: Ten patients were treated with our surgical protocol, and there was no conversion to laparotomy. The average total operation time was 223 minutes. The average duration of anesthesia was 260.2 minutes. The average docking time between the robot arm and Trocar was 17.5 minutes. The average intraoperative blood loss was 16 mL. No postoperative complications occurred in the 10 patients. The mean time to start drinking water after surgery was 2.4 days. The mean postoperative drainage tube removal time was 2.6 days. The average length of stay was 8.5 days. The scar assessment scale total scores of the 2 observers were (6.8 ± 1.23) and (7.4 ± 1.84), respectively. For every patient, there are only four abdominal surgery scars of which 75% of scars were hidden by underpants and 25% of scars were not covered. Conclusion: It is feasible and safe to perform whole-courses intraperitoneal robot-assisted choledochal cyst resection with Pfannenstiel incision in children under 1 year old. It also has a hidden incision effect and is worthy of promotion.

Efficacy of robot-assisted hepaticojejunostomy and laparoscopic-assisted hepaticojejunostomy in pediatric congenital choledochal dilatation: a system review and meta-analysis

PURPOSE

The efficacy of robot-assisted hepaticojejunostomy (RAHJ) and laparoscopic-assisted hepaticojejunostomy (LAHJ) in children with congenital choledochal dilatation has been a topic of much debate and controversy. The purpose of this study was to evaluate the role of RAHJ and LAHJ in pediatric congenital choledochal dilatation.

METHOD

The review program has been prospectively registered (PROSPEROID: CRD42022306868). We searched the PubMed, Embase, Cochrane, CBM, VIP, Web of Science, CNKI databases, and Wanfang databases from March 2021. The Mantel-Haenszel method and a random-effects model were used to figure out the hazard ratio (95% CI).

RESULTS

Ten studies evaluated eight hundred and sixty-nine subjects (three hundred and thirty-two in the robotic group and five hundred and thirty-seven in the laparoscopic group), meeting all inclusion criteria. Compared with the laparoscopic group, robotic group demonstrated fewer postoperative complications [p = 0.0009; OR = 0.34 (95% CI, 0.18-0.64); I² = 3%], shorter postoperative hospital stay [p < 00,001; MD = - 2.05 (95% CI, - 2.40-1.70); I² = 0%], and less intraoperative bleeding [p = 0.008; MD = - 10.80 (95% CI, - 18.80-2.81); I² = 99%]. There was no significant difference in operative time between the two groups [p = 0.10; MD = 24.53 (95% CI, - 5.11-54.17); I² = 99%]. The same situation happened in short-term complication outcomes [p = 0.06; RR = 0.45 (95% CI, 0.19-1.04); I² = 0%]. However, children in the RAHJ group had significantly lower levels of long-term complications [p = 0.04; OR = 0.41 (95% CI, 0.17-0.96); I² = 0%]. Hospitalization costs were significantly higher in the RAHJ group [p < 0.00001; OR = 27,113.86 (95% CI, 26,307.24-27,920.48); I² = 0%]. For overall complications, subgroup analysis of literature published after 2020 and of literature with high quality scores showed a significant decrease in the RAHJ group.

CONCLUSION

In children with congenital choledochal dilatation, RAHJ is associated with reduced intraoperative bleeding, postoperative complications, and length of stay. Robotic surgery has a bright future in the treatment of pediatric common hepatic duct cysts and deserves to be promoted and popularized.

Baseline assessment of enhanced recovery after pediatric surgery in mainland China

BACKGROUND

Enhanced recovery after surgery (ERAS) is a clinical pathway that optimizes perioperative management based on evidence-based medicine. ERAS has been gradually introduced to pediatric surgery in recent years. However, there are limited reports on its overall implementation. We aimed to determine the implementation of ERAS in patients who received pediatric surgery in mainland China.

METHODS

We designed a questionnaire involving 17 key ERAS elements and sent the questionnaire to 66 chiefs of pediatric surgery distributed throughout 31 provinces in mainland China to obtain a baseline assessment of the assimilation of ERAS protocols in the care of congenital biliary dilatation (CBD).

RESULTS

A total of 66 questionnaires were collected. The range of elements implemented at participating centers was 4-16, with a mean of 10.23. The least commonly practiced elements were administration of non-opioid preoperative analgesia (6 centers, 9.09%), prevention of postoperative nausea and vomiting [PONV] (9 centers, 13.64%), and postoperative pain management (26 centers, 39.39%).

CONCLUSIONS

The implementation of elements differed from center to center. Measures relying primarily on anesthesiologists had lower execution. The adherence to ERAS elements was often inhibited by a lack of institutional support, poor knowledge of ERAS protocols, and difficulties in coordinating multidisciplinary care, as well intransigence in changing surgical practices out of fear of liability for poor outcomes.

Modified single-port versus multiport laparoscopic choledochal cysts excision and Roux-en-Y hepaticojejunostomy: a retrospective comparative cohort study

BACKGROUND

The feasibility, benefit, and safety of multiport laparoscopic choledochal cyst (CDC) excision and Roux-en-Y hepaticoenterostomy (MPCH) have been consistently confirmed. Single-port laparoscopic CDC excision and Roux-en-Y hepaticoenterostomy (SPCH) has advantages of less traumatic and more cosmetic beneficial, it has been reported in some case series, but it is technically challenging. We propose a modified technique to reduce technical difficulty in performing SPCH. The safety and feasibility of modified SPCH were compared with those of conventional multiport laparoscopic CDC excision.

METHODS

A total of 43 consecutive patients who diagnosed with CDC by preoperative magnetic resonance cholangiopancreatography (MRCP) and underwent SPCH (n=24) and MPCH (n=19) for choledochal cyst (CDC) by a single surgeon between January 1, 2018, and January 1, 2021, were enrolled. The baseline clinical characteristics, efficacy and safety outcomes of short-term were compared.

RESULTS

The baseline clinical characteristics of the MPCH and SPCH groups are comparable. Average postoperative length of hospital stay was shorter in the SPCH group than in the MPCH group, but the difference was not statistically significant (7.00 vs. 7.58 days; P>0.99). The operation time (281.75 vs. 277.3 min; P=0.58) and the amount of blood loss (9.33 vs. 16.68 mL; P=0.57) were similar in both groups. A significantly greater number of drainage tubes were placed in the MPCH group compared to the SPCH group (11 vs. 5; P=0.01). One patient suffered from hepaticoenterostomy anastomosis stricture in the SPCH group.

CONCLUSIONS

The short-term outcome of modified SPCH is comparable with MPCH according to our study. It is easily adaptable treatment of CDC.

Imaging of fibropolycystic liver disease

Fibropolycystic liver diseases (FLDs) make up a rare spectrum of heritable hepatobiliary diseases resulting from congenital ductal plate malformations (DPMs) due to the dysfunction of proteins expressed on the primary cilia of cholangiocytes. The embryonic development of the ductal plate is key to understanding this spectrum of diseases. In particular, DPMs can result in various degrees of intrahepatic duct involvement and a wide spectrum of cholangiopathies, including congenital hepatic fibrosis, Caroli disease, polycystic liver disease, and Von Meyenberg complexes. The most common clinical manifestations of FLDs are portal hypertension, cholestasis, cholangitis, and (in rare cases) cholangiocarcinoma. This article reviews recent updates in the pathophysiology, imaging, and clinical management of FLDs.

Case report: Severe hepatic fibrosis induced by chronic cholestasis of congenital biliary dilation treated by laparoscopic surgery after immunonutrition support- An infantile case

INTRODUCTION

In some patients with congenital biliary dilation (CBD), biliary cirrhosis has been reported to rapidly progress from the neonatal period to the infantile period. We herein report an infantile case of CBD that showed severe biliary cirrhosis at the diagnosis, which was treated by laparoscopic surgery.

CASE PRESENTATION

A 16-month-old girl underwent conservative therapy for liver dysfunction and cholangitis on a remote island of our prefecture. She was transferred to our hospital after the detection of a huge dilated common bile duct on imaging at the previous hospital. Contrast-enhanced computed tomography showed a dilated common bile duct (maximum diameter: 5 cm), thus suggesting CBD. However, her laboratory data on admission showed a poor nutritional status and severe liver dysfunction (Alb, 2.5 mg/dl; AST, 79 IU/L; ALT, 43 IU/L; γ-GTP, 491 mg/dl; D-bil, 0.3 mg/dl; CHE, 90 IU/L; NH₃, 123 μg/dl). We initially performed laparoscopic exploration and bile drainage via the gallbladder, noting severe hepatic fibrosis resembling end-stage liver cirrhosis. After placing a drainage tube in the gallbladder, cholangiography was performed. Cholangiography showed Todani type IVa CBD with pancreaticobiliary maljunction. Contrast agent flowing into the duodenum could not be confirmed. The patient received liver-supporting therapy and nutritional support for 7 weeks before definitive surgery. Following the improvement of the hepatic synthetic capacity (Alb, 4.0 mg/dl; AST, 82 IU/L; ALT, 78 IU/L; γ-GTP, 157 mg/dl; D-bil, 0.2 mg/dl; CHE, 232 IU/L; NH₃, 75 μg/dl), we performed extrahepatic bile duct excision and hepaticojejunostomy laparoscopically. Laparoscopic surgery was successfully performed along with liver biopsy. Histopathologically, the liver specimen showed chronic hepatitis and fibrosis (F3A2). Biliary scintigraphy showed good bile excretion at postoperative day 15. The postoperative course uneventful, and the patient was discharged on the 23rd day after surgery. A needle liver biopsy six months later showed mild improvement of chronic hepatitis and fibrosis (F2-3A1). The patient was regularly followed at the outpatient clinic.

CONCLUSIONS

Severe liver fibrosis was suspected to be continuous cholestasis of CBD after birth. CBD with severe liver fibrosis may avoid liver transplantation by two-stage surgery with hepatoprotection therapy and immunonutritional support.
