Abstract
Background Type III choledochal cysts (CCs) are the rarest and least well-characterized of the five variants of biliary cysts. Only a few relevant studies have been conducted and a gold standard treatment for type III CCs is still lacking because of their scarcity. An unusual case of type III CC with choledochocele at the end of the distal common bile duct (CBD) with no bulging of the duodenum is presented here. Case presentation A 61-year-old woman presented to our department with repeated upper abdominal pain for one year. Laboratory examination revealed abnormal liver function and a slight increase in the white blood cell (WBC) count and proportion of neutrophils. In an MRCP of the patient, the distal CBD was found to have a cystic structure indicative of a type III CC. Endoscopic retrograde cholangiopancreatograpy (ERCP) revealed cystic findings compatible with Todani type III CCs. However, duodenoscopy did not show a bulge in the duodenum so laparoscopic cholecystectomy and Roux-en-Y hepaticojejunostomy were performed. In her 6-month follow-up, the patient reported that recovery from the operation was uneventful. Conclusions ERCP has become the gold standard for diagnosing type III CCs. Type III CCs can be treated minimally invasively with laparoscopic cholecystectomy and Roux-en-Y hepaticojejunostomy.

Endoscopic treatment of periampullary duodenal duplication cysts in children: Four case reports and review of the literature. World J Gastrointest Endosc 2021; 13:529-542. [PMID: 34733413 PMCID: PMC8546566 DOI: 10.4253/wjge.v13.i10.529] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2021] [Revised: 04/30/2021] [Accepted: 08/02/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Duodenal duplications are rare congenital anomalies of the gastrointestinal tract. As the periampullary variant is much rarer, literature is scant and only few authors have reported their experience in diagnosis and treatment, particularly with operative endoscopy.
CASE SUMARY To report our experience with the endoscopic treatment in a series of children with periampullary duodenal duplication cysts, focusing on the importance of obtaining an accurate preoperative anatomic assessment of the malformations. The pediatric periampullary duodenal duplication cyst literature is reviewed. We conducted a systematic review according to the PRISMA guidelines. The PubMed database was searched for original studies on “duodenal duplication”, “periampullary duplication” or “endoscopic management” published since 1990, involving patients younger than 18 years of age. Eligible study designs were case report, case series and reviews. We analyzed the data and reported the results in table and text. Fifteen eligible articles met the inclusion criteria with 16 patients, and analysis was extended to our additional 4 cases. Median age at diagnosis was 13.5 years. Endoscopic treatment was performed in 10 (50%) patients, with only 2 registered complications.
CONCLUSION Periampullary duodenal duplication cysts in pediatric patients are very rare. Our experience suggests that an accurate preoperative assessment is critical. In the presence of sludge or stones inside the duplication, endoscopic retrograde cholangio-pancreatography is mandatory to demonstrate a communication with the biliary tree. Endoscopic treatment resulted in a safe, minimally invasive and effective treatment. In periampullary duodenal duplication cyst endoscopically treated children, long-term follow-up is still necessary considering the potential malignant transformation at the duplication site.

Abstract
OBJECTIVE To identify the best mode for diagnosing and treating the patients with choledochal cysts. METHODS A retrospective study was performed with medical records of patients diagnosed with choledochal cysts from January 1994 to December 2017. In all cases, the diagnosis was based on ultrasound examination. All the patients underwent cyst resection and were divided in two groups: bile enteric anastomosis in the high portion of the common hepatic duct or in the dilated lower portion. RESULTS Eighty-one cases were studied. The age of presentation was 4 y 2 mo ± 4 y 1 mo, and the age for the surgical treatment was 5 y 5 mo ± 4 y 6 mo. In 61 cases, US was the only image examination performed. There were 67 cases of Todani type I (82.7%), 13 cases of type IV (16.0%) and one case of type III (1.2%). Nine patients (29.0%) in the first period and 2 patients (4.0%) in the second period presented with postoperative complications (p=0.016). CONCLUSION In patients with choledochal cysts, US is the only necessary diagnostic imaging. Performing the bile enteric anastomosis in the lower portion of the common hepatic duct is safer and has a lower risk of complications.

Abstract
BACKGROUND Choledochoceles may cause biliary obstruction and harbor malignancy. We conducted a 40-year systematic review of the literature for this rare anomaly. METHODS PubMed and Cochrane databases were accessed 1975-2015 using terms "choledochocele" or "choledochal cyst". Studies reviewed that met the following criteria: English language, published 1975-2015 with human subjects. RESULTS 325 patients with a choledochocele were identified, including 71 case reports and 254 cases within institutional reviews. 13 pediatric case reports of choledochocele exist, with abdominal pain being the most common symptom (n=11). The most frequent diagnostic and treatment modalities were ultrasound (n=10), and endoscopic sphincterotomy (n=5). No malignancies were reported. 58 adult case reports exist, with the most common presenting symptom being abdominal pain (n=54). Ultrasound was the frequently employed diagnostic modality (n=32). Open procedures were performed more often (n=30). Malignant lesions were identified in 5. In 42 institutional reviews, the frequency of choledochocele was 0.7%. Of those for whom treatment was reported, 69% underwent endoscopic sphincterotomy. CONCLUSION Choledochocele is a rare malformation. Similarities exist between pediatric and adult patients, but malignancy has only been reported in adults. An algorithm based on patient age, cyst size, lining and amenability to endoscopic resection may be considered as a treatment strategy for this uncommon condition.

Abstract
A 6-year-old girl presented with intermittent abdominal pain, without jaundice and a palpable mass in the epigastrium. Preoperative imaging and upper endoscopy suggested duodenal duplication. During surgery, the patient was diagnosed with a rare type of choledochal cyst—choledochocele (type 3b). The authors emphasize that, in children, choledochocele should be included in the differential diagnosis of cystic lesions located in the duodenal area and the head of the pancreas area, regardless of jaundice or abnormal liver function. Since mucosal histology showing duodenal mucosa did not match the final diagnosis, we suggest that three criteria should be met for the diagnosis of a choledochocele to be diagnosed: (1) a cyst protruding into the duodenal lumen; (2) filling with contrast during cholangiography and (3) a filling defect on X-ray barium meal.

Abstract
The duodenum is a unique segment of intestine, occupying both intra and extra-peritoneal locations. There is a wide spectrum of abnormalities of the duodenum that range from congenital anomalies to traumatic, inflammatory, and neoplastic entities. The duodenum may be overlooked on cross-sectional imaging due to its location and small size. Duodenal pathologies may, therefore, be missed or wrongly diagnosed. Knowledge about duodenal pathologies and optimal imaging techniques can increase diagnostic yield and permit optimal patient management. Conventionally, the duodenum was evaluated with upper GI studies on fluoroscopy; however, endoluminal evaluation is better performed with endoscopy. Additionally, a broad array of cross-sectional imaging modalities permits comprehensive assessment of the duodenum and surrounding viscera. While endoscopic sonography is increasingly used to locally stage duodenal malignancies, MDCT remains the primary modality widely used in the detection and characterization of duodenal abnormalities. MRI is used as a "problem solving" modality in select conditions. We present a comprehensive review of duodenal abnormalities with an emphasis on accurate diagnosis and management.

Abstract
Choledochoceles are cystic dilatations of the intraduodenal portion of the common bile duct. Although often classified as Type III biliary cysts, choledochoceles have distinctive demographic and anatomic features and a lower risk of malignancy than other types of choledochal cysts. Type A choledochoceles are cystic dilatations of a segment of the intra-ampullary bile duct and are located proximal to the ampullary orifice. Type B choledochoceles are diverticula of the intra-ampullary common channel and are located distal to the ampullary orifice; they can be distinguished from duodenal duplication cysts both anatomically and histologically. Both types of choledochocele may present with pancreatitis, biliary obstruction, or nonspecific gastrointestinal symptoms. Cross-sectional imaging, endoscopic ultrasound, and endoscopic retrograde cholangiopancreatography are useful for diagnosis. Choledochoceles may be drained or resected endoscopically. Surveillance for dysplasia should be considered for lesions that are not resected.

Abstract
The classification of choledochoceles as a type of choledochal cyst stems from the 1959 article by Alonso-Lej and colleagues describing 94 choledochal cysts, only 4 of which were choledochoceles. Even then, Alonso-Lej questioned the propriety of including the choledochocele, stating it was unclear "as to whether or not it originates from the same etiologic factors [as other choledochal cysts]". In 1971, Trout and Longmire also questioned the validity of classifying choledochoceles as choledochal cysts, noting the anatomic position article and variant mucosa of the choledochocele. Wearn and Wiot, in an article titled "Choledochocele: not a form of choledochal cyst", cite the differences in clinical presentation, demographics, and histology as reasons why choledochoceles represent separate entities from choledochal cysts. Over the ensuing decades, numerous investigators have questioned the legitimacy of classifying choledochoceles as choledochal cysts. In our recent series (the only one to our knowledge directly comparing patients with choledochocele and other [type I, II, IV, and V] choledochal cysts), patients with choledochoceles differed from patients with choledochal cysts in their age, gender, presenting symptoms, history of previous cholecystectomy, pancreatobiliary ductal anatomy, management, and most importantly, propensity to developing biliary malignancy. Based on the available cases of choledochoceles found in the literature, combined with the recent series from our institution, we conclude that choledochoceles seem to be distinct entities from choledochal cysts.

Abstract
OBJECTIVE The aim of this analysis was to report a multidisciplinary series comparing choledochoceles to Todani Types I, II, IV, and V choledochal cysts. SUMMARY BACKGROUND DATA Choledochoceles have been classified as Todani Type III choledochal cysts. However, most surgical series of choledochal cysts have reported few choledochoceles because they are managed primarily by endoscopists. METHODS Surgical, endoscopic, and radiologic records were reviewed at the Riley Children's Hospital and the Indiana University Hospitals to identify patients with choledochal cysts. Patient demographics, presenting symptoms, radiologic studies, associated abnormalities, surgical and endoscopic procedures as well as outcomes were reviewed. RESULTS A total of 146 patients with "choledochal cysts" including 45 children (31%) and 28 with choledochoceles (18%) were identified, which represents the largest Western series. Patients with choledochoceles were older (50.7 vs. 29.0 years, P < 0.05) and more likely to be male (43% vs. 19%, P < 0.05), to present with pancreatitis (48% vs. 24%, P < 0.05) rather than jaundice (11% vs. 30%, P < 0.05) or cholangitis (0% vs. 21%, P < 0.05), to have pancreas divisum (38% vs. 10%, P < 0.01), and to be managed with endoscopic therapy (79% vs. 17%, P < 0.01). Two patients with choledochoceles (7%) had pancreatic neoplasms. CONCLUSIONS Patients with choledochoceles differ from patients with choledochal cysts with respect to age, gender, presentation, pancreatic ductal anatomy, and their management. The association between choledochoceles and pancreas divisum is a new observation. Therefore, we conclude that classifications of choledochal cysts should not include choledochoceles.

Abstract
Type III choledochal cysts, also called choledochoceles, are rare cystic dilatations of the terminal biliary tree. We report the case of a 'closed choledochocele', in which the bile and ventral pancreatic ducts emptied into the cyst, but because there was no outlet into the duodenum, drainage was retrograde via the accessory duct. This type of choledochocele variant has never previously been described in the medical literature.

Abstract
BACKGROUND Choledochal cyst is an uncommon anomaly of the biliary tract. Experience with this disorder, with emphasis on the role of ERCP in management, is presented. METHODS All pertinent data for 13 patients with choledochal cyst seen between 1987 and 1998 were reviewed, retrospectively. OBSERVATIONS Cholangitis, either alone or associated with other findings, was the main presenting feature (69.23% of patients). Bilobar Caroli's disease was the most common cyst type (46.15% of patients). ERCP was diagnostic alone in 46.15% of patients and therapeutic in 53.85%. CONCLUSIONS Choledochal cyst is a complex condition that requires early diagnosis. Long-term management remains controversial, and guidelines for treatment require revision. Whether interventional ERCP will obviate the need for surgery or alter the malignant potential of the disorder remains uncertain.

Abstract
Choledochocele is a rare cystic congenital malformation of the distal common bile duct, the precise pathogenesis of which remains unclear. It is usually diagnosed in adulthood after many examinations for unclear digestive symptoms, as in the patient whose case is described herein. Of all the diagnostic techniques available, endoscopic retrograde cholangiography (ERCP) seems to be the best; however, it is an invasive procedure associated with some morbidity. Spiral computed tomographic cholangiography with three-dimensional reconstruction is also an interesting screening technique. Malignant transformation of a choledochocele occurs very rarely, compared with other cystic malformations of the biliary tract. If a choledochocele is small and symptomatic, the lesion can be treated by endoscopic sphincterotomy, but larger cysts are more effectively removed by a surgical cystoduodenostomy. We present herein the case of a 25-year-old woman admitted to our hospital in March 1998 with upper right quadrant abdominal pain caused by a choledochocele, who was successfully treated by a cystoduodenostomy.

Abstract
BACKGROUND Choledochocele is a rare abnormality involving the intramural segment of the common bile duct. ERCP is essential to demonstrate a choledochocele. The aim of this study was to investigate the duodenoscopic and cholangiographic findings during ERCP. METHODS Over a 4-year period, 17 symptomatic patients (8 men, 9 women; age range 45 to 83 years) were identified as having choledochoceles. The diagnosis of choledochocele was made by both duodenoscopic and cholangiographic findings. RESULTS As a characteristic duodenoscopic finding, the enlarged bulging papilla was noted in 8 patients (47%), whereas a normal-appearing papilla was noted in 9 patients (53%) before the injection of contrast media. However, in all 17 patients progressive enlargement or ballooning of the papilla was noted during contrast injection. The maximum diameter of the choledochocele, determined by cholangiography, was significantly larger (19 +/-4 mm) in patients with initially bulging papilla than in those with normal-appearing papilla (9+/-3 mm) (p < 0.05). CONCLUSIONS Ballooning of the papilla during contrast injection may be a specific duodenoscopic finding for choledochocele. To avoid missing the diagnosis of a choledochocele, especially when it is small, it is important to watch the papilla carefully during contrast injection.

Abstract
BACKGROUND Choledochoceles (type III biliary cysts) are cystic dilations of the terminal common bile duct or common pancreatobiliary channel. Although no size criteria have been defined, it is generally assumed these must be large. However, we describe patients who do not meet the perceived size criteria for choledochoceles, but who nonetheless have a dilated common pancreatobiliary channel. METHODS We reviewed the presenting symptoms, endoscopic and radiographic findings, and response to endoscopic therapy of patients meeting our criteria for the dilated common channel syndrome. RESULTS Of 2847 patients undergoing ERCP, 100 (3.5%) had the dilated common channel syndrome. Common presenting symptoms and signs included abdominal pain in 97%, abnormal liver function test(s) in 66%, and a history of acute or recurrent pancreatitis in 46%. A bulge was visible above the papilla in 88%, with a dilated common bile duct in 54% and a dilated pancreatic duct in 28%. After endoscopic unroofing of the common channel, 77% had complete and long-lasting resolution of symptoms, 18% had partial or transient improvement, and 5% had no change. CONCLUSIONS Although classic choledochoceles are rare, a lesser degree of dilation of the common channel is more frequent than generally appreciated. We postulate that this finding represents an "incomplete," acquired form of choledochocele, possibly caused by underlying papillary stenosis. Whatever the etiology and appropriate term, the presence of a dilated common channel predicts a high rate of clinical response to endoscopic therapy.

Abstract
Endoscopic retrograde cholangiopancreatography, endoscopic sphincterotomy, and endoscopic biliary drainage have dramatically changed the diagnosis and management of disorders of the pancreas and hepatobiliary tract. Endoscopic retrograde cholangiopancreatography will provide a high-resolution study that will define accurately the nature and location of the disease process involving the pancreas or bile ducts. Although sonography, CT, and, recently, MRI may provide clues to the diagnosis, it often remains for endoscopic retrograde cholangiopancreatography to establish the diagnosis with certainty. Endoscopic sphincterotomy has been invaluable in the management of common bile-duct stones. In patients who have had their gallbladders removed, sphincterotomy has avoided reoperation in the same field and the risk of general anesthesia. Sphincterotomy also is assuming an increasingly important role in the management of common-duct stones in patients with their gallbladders in situ who are poor operative candidates. In these patients, sphincterotomy likewise avoids the risk of general anesthesia and the surgical stress of opening a major body cavity. The technique has also proved to be helpful in the palliative treatment of ampullary and distal common bile-duct carcinomas in those patients who are poor operative candidates. Finally, sphincterotomy has found a role in the treatment of choledochal cysts and may provide relief of pain in those patients with the elusive diagnoses of postcholecystectomy syndromes, biliary dyskinesias, and sphincter of Oddi dysfunction. Endoscopic biliary drainage is becoming an increasingly popular option for the palliation of malignant biliary obstruction. In those patients who are poor operative candidates, the risk of general anesthesia and major surgery is avoided. In those patients with obviously incurable tumors, endoscopic drainage allows for a brief hospitalization without surgery in the face of a short life expectancy.
