Food impaction in a duodenal diverticulum as an unusual cause of biliary obstruction: case reports and review of the literature

Rapunzel syndrome in adult with mysterious presentation: a rare case report with literature review

Bezoars are indigestible foreign material in the gastrointestinal tract (GIT). A phytobezoar is a mass of plant material, while a trichobezoar consists of matted hair. This is found most commonly in the stomach in children who chew their long hair. When a gastric trichobezoar extends to the duodenum or jejunum, this is known as Rapunzel syndrome (RS), after a famous Brothers' Grimm fairy tale. Our patient presented with haematemesis, localised peritonitis, a palpable epigastric mass, coagulopathy, severe anaemia and deranged liver function tests. An abdominal computed tomography scan was suggestive of a bezoar; gastroduodenoscopy confirmed the diagnosis. Treatment of trichobezoars normally involve endoscopic removal or gastrotomy and psychiatric intervention. They may also cause haematemesis, gastric outlet obstruction, gastric ulceration and perforation, multiple jejuno-jejunal intussusception, acute pancreatitis and cholestatic jaundice. Trichobezoar was first reported in the 18th century by Baudamant in a 16-year-old boy. RS was first described in 1968.

The Impact of Duodenal Diverticuli and the Execution of Endoscopic Retrograde Cholangiopancreaticography

Introduction. Duodenal diverticuli alter the anatomy of the papillary region and can make an ERCP difficult. Aim. To study the outcome of ERCP in cases of duodenal diverticuli. Patients and Methods. Consecutive ERCPs in a period of 24 years were included. Endoscopy reports were studied for presence of diverticuli. Success of the procedure and findings were noted. Clinical records were searched for clinical presentation of the patient. Patients without duodenal diverticuli were used as comparison. Results. 2795 procedures were done in 2092 patients. Of these, 211 (10%) had diverticuli. Diverticuli occurred significantly more often in women (p < 0.001). ERCP was significantly more often inconclusive in cases of a diverticulum, 12.8% versus 6.3%, p < 0.001. In cases of a successful ERCP, patients with diverticuli showed more often no abnormalities in the bile duct, 26% versus 17%, p < 0.001. In 64% of cases, the reason for ERCP was cholestasis. There was no significant difference in presence of stones or cholangitis. Biliary pancreatitis was seen more often in patients without diverticuli, 4.4% versus 1.4%, p = 0.04. This was also the case for malignancies, 18.5% versus 6.6%, p < 0.001. Conclusion. It is concluded that duodenal diverticuli can be responsible for cholestasis. Presence of a diverticulum in the duodenum makes the ERCP procedure more complex.

Impact of periampullary diverticula on the outcome and fluoroscopy time in endoscopic retrograde cholangiopancreatography

BACKGROUND

It is unclear whether the presence of periampullary diverticula (PAD) affects technical success and complication rates during endoscopic retrograde cholangiopancreatography (ERCP). Moreover, the impact of PAD on fluoroscopy duration is still unknown. The present study aimed to investigate the success rate and difficulty of common bile duct (CBD) cannulation, post-procedure complications and fluoroscopy duration in patients with and without PAD.

METHODS

Patients from January 2008 to December 2010 with PAD (group A) and without PAD (group B) and similar indications for therapeutic ERCP were prospectively compared. The comparison included patient characteristics, findings of ERCP, and details of procedure and fluoroscopy time. The influence of papilla's location with respect to the diverticulum on procedure was also investigated.

RESULTS

A total of 428 consecutive patients who had undergone therapeutic ERCP for similar indications were divided in two groups according to the presence (group A, 107 patients) or absence (group B, 321 patients) of PAD. The mean age and ASA score of the patients with PAD were significantly higher than those patients without PAD. The main indication was choledocholithiasis. Successful final CBD cannulation was achieved in 97.20% of the patients in group A vs 99.69% in group B (P=0.05). CBD diameter, number of stones and the largest stone size were significantly higher in group A than group B (P<0.001). Complete clearance of the CBD after the first attempt was achieved in 85.86% and 94.75% of the patients in groups A and B, respectively (P=0.03). In both groups, the time needed to complete the procedure and fluoroscopy time was significantly longer in patients with PAD (22.87 vs 18.99 minutes, P<0.001; 76.51 vs 47.42 seconds, P<0.001). There was no significant difference between the two groups in the complication rate. The type of papilla's location with respect to the diverticulum did not influence the total cannulation rate and post-procedure complications.

CONCLUSION

The presence of a PAD does not affect the success rate and complications of therapeutic ERCP in expert hands; however, the fluoroscopy time is significantly longer in patients with PAD.

Duodenal obstruction following acute pancreatitis caused by a large duodenal diverticular bezoar

Bezoars are concretions of indigestible materials in the gastrointestinal tract. It generally develops in patients with previous gastric surgery or patients with delayed gastric emptying. Cases of periampullary duodenal divericular bezoar are rare. Clinical manifestations by a bezoar vary from no symptom to acute abdominal syndrome depending on the location of the bezoar. Biliary obstruction or acute pancreatitis caused by a bezoar has been rarely reported. Small bowel obstruction by a bezoar is also rare, but it is a complication that requires surgery. This is a case of acute pancreatitis and subsequent duodenal obstruction caused by a large duodenal bezoar migrating from a periampullary diverticulum to the duodenal lumen, which mimicked pancreatic abscess or microperforation on abdominal computerized tomography. The patient underwent surgical removal of the bezoar and recovered completely.

Surgical management of pancreaticobiliary disease associated with juxtapapillary duodenal diverticula: case series and review of the literature

INTRODUCTION

Juxtapapillary duodenal diverticula (DD), although usually asymptomatic, are occasionally associated with pancreaticobiliary conditions such as recurrent bile duct stones, cholangitis, and pancreatitis.

MATERIALS AND METHODS

An unusual case of DD associated with a dorsal duct stricture in a patient with recurrent pancreatitis and pancreas divisum is presented along with three additional instances of surgically treated DD and a review of the literature.

RESULTS

The role of surgical intervention depends upon the specific nature of the presentation and the anatomical relationship of the diverticulum to the ampullary and pancreaticobiliary ductal system.

CONCLUSION

Operations that divert bile and the food stream from DD are preferred over diverticulectomy.

Influence of juxtapapillary diverticula on the success or difficulty of cannulation and complication rate

BACKGROUND

Periampullary diverticula (PAD) are found in 9% to 32% of patients who undergo an ERCP. Published studies confer conflicting results regarding the true impact of PAD on the technical success and complications of ERCP.

OBJECTIVE

The aim of the study was to investigate and compare success rate, difficulty at cannulation, and complications between patients with and without PAD, as well as to identify independent factors that influence the difficulty at cannulation.

DESIGN

A prospective study.

SETTING

Tzaneio General Hospital.

PATIENTS

A total of 601 consecutive patients who underwent an ERCP were divided into 2 groups according to the presence (group A, 117 patients) or absence (group B, 484 patients) of PAD. Patients with undetectable papilla were excluded from the study cohort. The incidence of undetectable papilla was 8.3% in patients with duodenal diverticula and 0.9% in patients without duodenal diverticula (P = .000).

RESULTS

Successful cannulation was achieved in up to 94.9% and 94.8% in groups A and B, respectively. The effort and difficulty at attempting this goal was different between the groups (43.5% vs 59.1%, P = .003), because patients without PAD were subjected to more vigorous attempts or even the pre-cut technique to attain a cholangiogram. There was no significant difference between the groups in the complication rate either in total or in any particular patient. Multivariate logistic regression analysis showed 3 of the variables, namely choledocholithiasis, abnormal papilla, and the presence of diverticula, remained significant, and all of them presented with odds ratios indicating an easier cannulation attempt.

LIMITATION

A nonrandomized study.

CONCLUSIONS

The finding of a periampullary diverticulum during an ERCP should not be considered an obstacle to a successful cannulation and, furthermore, may be an indicator of an easier cannulation attempt, provided that the papilla can be found with confidence. Concerns about increased complications are not substantiated in this study.

Recurrent bacterial cholangitis due to a juxtapapillary diverticulum

We present a patient with recurrent bacterial cholangitis. Endoscopic retrograde cholangiopancreatography did not show evidence for choledocholithiasis or obstructing abnormalities of the common bile duct. However, a juxtapapillary diverticulum was situated at the edge of the papilla of Vater. We postulate that a juxtapapillary diverticulum can obstruct biliary flow due to its anatomical relation with the papilla, which may predispose to bacterial cholangitis. This might be prevented by sphincterotomy of the papilla.
