Endoscopic retrograde cholangiopancreatography-related perforations: Diagnosis and management

A systematic review of the management and outcome of ERCP related duodenal perforations using a standardized classification system

INTRODUCTION

The incidence of duodenal perforation after ERCP ranges from 0.09% to 1.67% and mortality up to 8%.

METHODS

This systematic review was registered in Prospective Register of Systematic Reviews, PROSPERO. Stapfer classification of ERCP-related duodenal perforations was used.

RESULTS

The systematic search yielded 259 articles. Most frequent post-ERCP perforation was Stapfer type II (58.4%), type I second most frequent perforation (17.8%) followed by Stapfer type III in 13.2% and type IV in 10.6%. Rate of NOM was lowest in Stapfer type I perforations (13%), moderate in type III lesions (58.1%) and high in other types of perforations (84.2% in type II and 84.6% in IV). In patients underwent early surgical treatment (<24 h from ERCP) the most frequent operation was simple duodenal suture with or without omentopexy (93.7%). In patients undergoing late surgical treatment (>24 h from ERCP) interventions performed were more complex. In type I lesions post-operative mortality rate was higher in patients underwent late operation (>24 h). In type I lesions, failure of NOM occurred in 42.8% of patients. In type II failure of NOM occurred in 28.9% of patients and in type III there was failure of NOM in only 11.1%, none in type IV. Postoperative mortality after NOM failure was 75% in type I, 22.5% in type II and none died after surgical treatment for failure of NOM in type III perforations.

CONCLUSIONS

This systematic review showed that in patients with Stapfer type I lesions, early surgical treatment gives better results, however the opposite seems true in Stapfer III and IV lesions.

Clinical outcomes of ERCP-related retroperitoneal perforations

Endoscopic retrograde cholangiopancreatography (ERCP)-related perforations represent rare but often severe conditions. While lesions with intraperitoneal perforation have an almost imperative indication to surgery, whether or not to manage retroperitoneal perforations surgically is still an area of debate. The aim of the present work was to review the available clinical evidence on the operatively and medically treated ERCP-related retroperitoneal perforations. From MEDLINE/PubMed databases 137 patients with retroperitoneal perforation were included from 12 studies that met the selection criteria for data investigation and analysis. Twenty-four patients were treated by prompt surgery; 113 were primarily managed conservatively and about 20% of these patients required surgery subsequently. Overall, the morbidity and mortality were 15.4% and 6.6%, respectively. Although most patients with retroperitoneal perforation may benefit from a non-operative management, a considerable number of patients fail to respond to medical treatment and require surgery afterwards. Identifying those patients who are at highest risk of poor outcome after conservative treatment should be considered a research priority.

Endoscopic Closure for EUS and ERCP Related Duodenal Perforation by Endoclips

Objective. To investigate the therapeutic safety, feasibility, and efficacy of endoclips for closing the endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) related duodenal perforation in a retrospective study from a single center. Methods. Patients who developed EUS and ERCP related duodenal perforation between January 2012 and January 2015 were included in the study. All the cases underwent endoscopic closure by endoclips, and the efficacy, feasibility, and safety of this technique were evaluated. Results. During the study period, a total of 17,406 patients were treated by EUS and/or ERCP. EUS and ERCP related duodenal perforation occurred in 9 cases (0.05%): 2 males and 7 females. The mean age was 69 years (range: 59-79 years). The success rate of endoscopic closure by endoclips was 100%. The mean procedure time was 45 ± 12.5 min. The mean number of endoclips placed for the closure of the duodenal perforation was 7 ± 3.2. All the patients recovered completely without any severe complications. Conclusion. The endoscopic closure by using endoclips is recommended as the first-line treatment for duodenal perforation associated with EUS and ERCP.

Recent Advanced Endoscopic Management of Endoscopic Retrograde Cholangiopancreatography Related Duodenal Perforations

The management strategy for endoscopic retrograde cholangiopancreatography-related duodenal perforation can be determined based on the site and extent of injury, the patient’s condition, and time to diagnosis. Most cases of perivaterian or bile duct perforation can be managed with a biliary stent or nasobiliary drainage. Duodenal wall perforations had been treated with immediate surgical repair. However, with the development of endoscopic devices and techniques, endoscopic closure has been reported to be a safe and effective treatment that uses through-the-scope clips, ligation band, fibrin glue, endoclips and endoloops, an over-the-scope clipping device, suturing devices, covering luminal stents, and open-pore film drainage. Endoscopic therapy could be instituted in selected patients in whom perforation was identified early or during the procedure. Early diagnosis, proper conservative management, and effective endoscopic closure are required for favorable outcomes of non-surgical management. If endoscopic treatment fails, or in the cases of clinical deterioration, prompt surgical management should be considered.
