Cutaneous stoma in the roux limb of hepaticojejunostomy (hepaticocutaneous jejunostomy): useful access for intrahepatic stone extraction

Surgical aspects of choledochal cyst in children and adults: an experience of 106 cases

PURPOSE

To describe clinical features of choledochal cyst (CC) patients in terms of demographic data, clinical presentation, investigations, treatment, and outcomes among children and adults.

METHODS

The medical records of patients undergoing choledochal cyst (CC) surgery from 2002 to 2021 at a university hospital were retrospectively reviewed. The patients were divided into two groups: children (< 15 years) and adults (≥ 15 years). Descriptive statistics were used.

RESULTS

There were 106 cases of CC (Female/male = 88/18, children/adult = 53/53). Abdominal pain was the predominant presenting symptom, followed by jaundice in both groups. Adults were significantly more prone to present with abdominal pain compared to children (86.8% vs. 52.8%; p < 0.001), while children were more likely to experience acholic stool than adults (22.6% vs. 3.8%; p = 0.004). Ultrasound was the preferred investigation screening modality (75.5%). Most patients were presented with type I CC (71.7%). Laparoscopic-assisted approach was performed in 8.5%. CC excision with roux-en-y hepatico-jejunostomy was the main procedure (88.7%). Adults had a higher incidence of post-op complications, including stones, anastomosis stricture, abdominal collection, and cholangitis. Adults were significantly more likely to require intervention after surgery, compared to children (26.4% vs. 5.7%; p = 0.04).

CONCLUSIONS

Ultrasound was the most common screening tool for diagnosis. Postoperatively, adults with CC experience more serious post-op complications compared to children. This could be attributed to long-standing cystic inflammation. Therefore, prompt definitive surgery is recommended for CC patients.

Therapeutic Role of Subcutaneous Access Loop Created Adjunct to Hepaticojejunostomy for Management of Bile Duct Injury

BACKGROUND

Roux-en-Y hepaticojejunostomy (RYHJ) is usually required for major bile duct injury (BDI) as a definitive treatment. Hepaticojejunostomy anastomotic stricture (HJAS) is the most feared long-term complication following RYHJ. The ideal management of HJAS remains undefined. The provision of permanent endoscopic access to the bilio-enteric anastomotic site can make endoscopic management of HJAS feasible and attractive option. In this cohort study, we aimed to evaluate short- and long-term outcomes of subcutaneous access loop created adjunct to RYHJ (RYHJ-SA) for management of BDI and its usefulness for endoscopic management of anastomotic stricture if occurred.

MATERIALS AND METHODS

This is a prospective study including patients who were diagnosed with iatrogenic BDI and underwent hepaticojejunostomy with subcutaneous access loop between September 2017 and September 2019.

RESULTS

This study included a total number of 21 patients whom ages ranged between 18 and 68 years. During follow-up, three cases had HJAS. One patient had the access loop in subcutaneous position. Endoscopy was done but failed to dilate the stricture. The other 2 patients had the access loop in subfascial position. Endoscopy of them failed to enter the access loop due to failure of fluoroscopy to identify the access loop. The three cases underwent redo-hepaticojejunostomy. Parajejunal (parastomal) hernia occurs in 2 patients in whom the access loop was fixed subcutaneous position.

CONCLUSION

In conclusion, modified RYHJ with subcutaneous access loop (RYHJ-SA) is associated with reduced quality of life and patient satisfaction. Moreover, its role in endoscopic management of HJAS after biliary reconstruction for major BDI is limited.

Hepaticojejunostomy with gastric access loop versus conventional hepaticojejunostomy: a randomized trial

Roux-en-Y hepaticojejunostomy (RYHJ) with the provision of "gastric access loop" was developed to shorten the distance traveled by the endoscope to reach hepaticojejunostomy (HJ) anastomotic site. The aim of our study was to assess modified RYHJ with gastric access loop (RYHJ-GA) and compare it with conventional RYHJ (RYHJ-C) regarding short- and long-term outcomes and, moreover, to evaluate the feasibility and results of future endoscopic access of the modified bilio-enteric anastomosis. Patients eligible for RYHJ between September 2017 and December 2019 were allocated randomly to receive either RYHJ-C or RYHJ-GA. Fifty-two patients were randomly assigned to RYHJ-C (n = 26) or RYHJ-GA (n = 26). Three cases in RYHJ-C and 4 cases in RYHJ- GA developed HJ anastomotic stricture (HJAS) (P=0.68). 3 cases of RYHJ-GA had successful endoscopic dilation and balloon sweeping of biliary mud (one case) or stones (2 cases). Revisional surgery was needed in 2 cases of RYHJ-C and 1 case in RYHJ-GA (P=0.68). Modified RYHJ with gastric access loop is comparable to the classic hepaticojejunostomy regarding complications. However, gastric access enables easy endoscopic access for the management of future HJAS. This modification should be considered in patients with a high risk of HJAS during long-term follow-up.The trial registration number (TRN) and date of registration:ClinicalTrials.gov (NCT03252379), August 17, 2017.

Postoperative anastomotic stricture following excision of choledochal cyst: a systematic review and meta-analysis

PURPOSE

Postoperative anastomotic stricture (PAS) is a well-known complication after correcting choledochal cyst (CC). Although the exact cause of PAS is unknown, various risk factors, such as Todani classification type IV-A, hepaticoduodenostomy, and narrow anastomosis have been reported to be associated with PAS. As far as we know, there is no report with a cumulative analysis of such risk factors of PAS. This systematic review and meta-analysis aimed to investigate the risk factors of PAS following surgical correction of CC in children.

METHODS

A systematic literature search for relevant articles was performed in four databases using the combinations of the following terms "Congenital biliary dilatation", "Congenital choledochal cyst", "Choledochal cyst", "Stenosis", "Stricture", and "Complication" for studies published between 1973 and 2022. The relevant cohorts of PAS were systematically searched for clinical presentation and outcomes.

RESULTS

The search strategy identified 795 reports. Seventy studies met the defined inclusion criteria, reporting a total of 206 patients with PAS. There is no prospective study in this search. The incidence of PAS was 2.1%. The proportion of Todani classification of the patient with PAS was higher in type IV-A with significant difference (2.0% in type I and 10.1% in type IV-A (p = 0.001)). Fourteen studies reported a comparison between hepaticojejunostomy and hepaticoduodenostomy. There was no significant difference between the two groups (p = 0.36). Four studies reported the diameter of the anastomosis at the primary surgery. The mean diameter was 12.5 mm. Nine studies reported a comparison between laparoscopic surgery and open surgery. Pooled odds ratio of PAS did not show a statistical difference (p = 0.29).

CONCLUSIONS

This study suggests that close careful follow-up is important in the patients with type IV-A of CC who underwent excision surgery, considering the possibility of PAS.

Classification and management of hepatolithiasis: A high-volume, single-center's experience

Hepatolithiasis is endemic to East Asia, but immigration from the region means that this rare but emerging disease will pose a therapeutic challenge to doctors in the West as well. Curative management of hepatolithiasis is difficult since its etiology has not been fully elucidated. Hepatectomy is the best approach to treating hepatolithiasis. Here, we propose a novel classification of hepatolithiasis and describe features of each type. We then relate our experience with various forms of hepatectomy to treat different types of hepatolithiasis. Surgery should be indicated for all cases of hepatolithiasis. The proposed classification will help to determine surgical strategies. Better selection of which patients should undergo a hepatectomy will lead to better outcomes.

Piezoelectric extracorporeal shockwave lithotripsy for bile duct stone formation after choledochal cyst excision

We report a case of bile duct stones in which piezoelectric extracorporeal shockwave lithotripsy (ESWL) was highly effective for the clearance of stones. A 16-year-old girl, who had undergone excision of a choledochal cyst when she was 3 years old, presented a spiking fever and colic abdominal pain. Radiological investigations showed two large stones incarcerating to the proximal end of hepatico-jejunostomy anastomosis. Massive debris was also present in intrahepatic bile duct proximal to the anastomosis. She underwent piezoelectric ESWL with an EDAP LT02 lithotripter. An average of 40 min ESWL session was repeated at intervals of 2 or 3 days. Neither anesthetic nor sedative treatment was required. By the end of the sixth session, the stones incarcerated were fragmented and the debris in the intrahepatic bile duct was completely eliminated. We conclude that piezoelectric ESWL is a less invasive, effective and repeatable method, therefore, it could be a treatment of choice for bile duct stone formation after choledochal cyst excision.

Clinical presentations and predisposing factors of cholelithiasis and sludge in children

BACKGROUND

In contrast to adults, little is known about the epidemiology and the best therapeutic regimen for cholelithiasis and sludge in children.

METHODS

Eighty-two children with cholelithiasis detected by ultrasonography were studied from 0 to 18 years of age with regard to cause, symptomatology, and treatment outcome. Seventy-five children with sludge within the same age group were studied as well.

RESULTS

Idiopathic gallstones were found in 19 (23%) patients, and 32 (39%) had gallstones in association with a hemolytic disease. Predominant factors associated with the development of gallstones and clinical presentation differed with age. In patients with sludge, total parenteral nutrition and systemic infection or administration of antibiotics were most frequently found to be possible predisposing factors. Sludge can develop and disappear within a few days. Complications of cholelithiasis were observed in 13 patients. Cholecystectomy was performed in 41 patients and therapeutic endoscopic retrograde cholangiopancreatography (ERCP) with stone extraction in 9 patients; 32 children were not treated. After a follow-up (mean, 4.6 years) in 50 patients, 46% of the children who had cholecystectomy or therapeutic ERCP experienced clinical recurrence of abdominal symptoms. In the patients who did not receive surgical or endoscopic therapy during the follow-up, no complications occurred, and only one patient experienced abdominal symptoms during follow-up.

CONCLUSIONS

The difference in associated conditions may indicate that the pathogenesis of cholelithiasis and sludge differ as well. Furthermore, sludge should be viewed as a dynamic condition not predisposing for the development of gallstones, per se. Cholecystectomy should not be performed routinely but only after careful selection in patients at risk for complications.

Virtual intraluminal endoscopy: a new method for evaluation and management of choledochal cyst

A 12-year-old girl who suffered from cholangitis was treated successfully with appropriate antibiotics. She had undergone an operation in mainland China, the exact nature of which was unknown. After an ultrasound study, she underwent a helical computed tomography (CT) cholangiogram using intravenous meglumine iodoxamine. The volume data were transferred to a workstation and virtual endoscopy rendering reconstruction of bile ducts was performed. Findings of this study showed that she had cyst excision with hepaticojejunostomy (HJ), and her intrahepatic ducts were packed with stones. Virtual endoscopy gave the impression that the examiner was flying inside the lumen and showed the stricture at the HJ anastomosis, the inner surface of the bile ducts, areas of dilated intrahepatic ducts, and the intrahepatic stones. The study overcame the need for an invasive study such as a percutaneous transhepatic cholangiography (PTC) and also facilitated appropriate surgical treatment in a timely fashion. It is believed that virtual intraluminal endoscopy (VIE) is helpful in the evaluation and management of selected cases of choledochal cyst.

Recurrent pyogenic cholangitis

BACKGROUND

Recurrent pyogenic cholangitis is a complex biliary tract disease characterized by intrahepatic pigment stones, endemic to Southeast Asia and seen with increasing frequency in the United States. The purpose of this study was to review the management of this disorder in a county hospital.

METHODS

A retrospective review of 45 patients with recurrent pyogenic cholangitis evaluated between 1984 and 1995. The clinical and surgical management of patients with localized versus bilateral hepatolithiasis were compared.

RESULTS

The prevalence of recurrent pyogenic cholangitis at our hospital has more than doubled since 1983. Fourteen of 45 patients (31%) had bilateral disease and required more abdominal computed tomography scans (P < 0.01), percutaneous cholangiograms (P < 0.05), endoscopies (P < 0.01), clinic visits (P < 0.05), and hospital admissions (P < 0.02) as compared with patients with localized disease.

CONCLUSIONS

The effective treatment of recurrent pyogenic cholangitis requires definition of the patients' intrahepatic distribution of disease, prior to surgical intervention, and the coordinated efforts of gastroenterologists, radiologists, and surgeons.

Hepatolithiasis and biliary parasites

Hepatolithiasis, or the presence of intrahepatic stones, is prevalent in East Asia and is characterized by the finding of stones within the intrahepatic bile ducts proximal to the confluence of the right and left hepatic ducts. Bile stasis and bacterial infection have been incriminated as the major aetiopathogenic factors. Clinical features include recurrent pyogenic cholangitis, multiple liver abscesses, secondary biliary cirrhosis and cholangiocarcinoma. The goals of management include accurate localization of pathologies, control of biliary sepsis and the elimination of stones and stasis. Ultrasonography, computed tomography and direct cholangiography complement each other in defining the stones, strictures and degree of liver damage. Non-operative biliary decompression by endoscopy and interventional radiology is effective in controlling the infection, but surgery remains the mainstay for the treatment of stones and strictures. Intra-operative ultrasound and flexible choledochoscopy, combined with percutaneous transhepatic cholangioscopy and intraductal lithotripsy, facilitate stone removal. Balloon dilatation and biliary stenting serve to open the bile duct strictures. The creation of a hepaticocutaneous jejunostomy after conventional surgery allows atraumatic access to the biliary system for the removal of recurrent stones. The management of biliary parasites begins with conservative measures, including analgesics and anti-helminthic therapy. In refractory cases or patients with acute cholangitis, endoscopic biliary drainage and the extraction of worms may be necessary. Improvement in sanitation plays a crucial role in the epidemiological control of these biliary diseases.

Early and late results of excision of choledochal cysts

BACKGROUND/PURPOSE

Reports on the late results of choledochal cyst excision with hepaticojejunostomy in children are relatively few.

METHODS

Of the 84 patients who had choledochal cyst who came under our care, 79 have had definitive surgery, three are awaiting surgery, one is being observed with Caroli's disease, and the parents of one child have refused surgery. Thirty-eight patients treated decades ago had internal drainage procedures. Since 1972, 41 patients have had cyst excision with hepaticojejunostomy using a 40-cm Roux loop without an antireflux procedure. Early complications in those who underwent cyst excision with hepaticojejunostomy included anastomotic leak in three patients who required reoperation, cholangitis in two, and fluid collection in the gall-bladder bed that required no intervention in one.

RESULTS

During a follow-up period ranging from 4 months to 17 years (mean, 8.5 years), anastomotic stricture, cholangitis, and intrahepatic stone formation developed in two children after being well for 8 years and over 11 years. These children required additional surgical procedures to overcome their problems. Asymptomatic intrahepatic stones 2 years after cyst excision with hepaticojejunostomy developed in a third child. There was no mortality in the entire group that underwent cyst excision and they are all enjoying a good quality of life.

CONCLUSIONS

Careful, long-term follow-up is important in children who have choledochal cyst excision with hepaticojejunostomy.
