Endoscopic duodenal perforation: surgical strategies in a regional centre

Diagnosis and management of type II endoscopic retrograde cholangiopancreatography-related perforations: a multicenter retrospective study

BACKGROUND

The management of type II endoscopic retrograde cholangiopancreatography (ERCP)-related perforation is still controversial. This study aimed to compare the effects of covered self-expandable metallic stent (SEMS), surgery, and conservative treatment for type II perforation.

METHODS

From January 2010 to December 2021, this study collected relevant data from five large hospitals in China. The data of ERCP difficulty grading and ERCP-related perforation in 26,673 cases that underwent ERCP during 11 years were retrospectively analyzed. Of 55 patients with type II perforation, 41 patients were implanted with a biliary covered SEMS (stent group), 10 underwent surgery (surgery group), and 4 received conservative treatment (conservative group).

RESULTS

Among the 55 patients with type II perforation, ERCP and computed tomography diagnostic rates of type II perforation were 10.91% (6/55) and 89.09% (49/55), respectively. The incidence of type II perforation in grade 5 ERCP (0.43%, 11/2,537) was significantly higher than that in grade 1-3 ERCP (0.16%, 32/19,471). (P = 0.004) and grade 1-4 ERCP (0.26%,12/4,665) (P = 0.008), respectively. Among the 10 patients in the surgical group, primary repair was performed in only 7 patients in whom location of the perforation could be identified. The incidence of retroperitoneal abscess was significantly lower in the stent group than in the surgery group (P = 0.018) and the conservative group (P = 0.001), respectively. The average hospital stay in the stent group was shorter than that in the surgery group (P = 0.000) and conservative group (P = 0.001), respectively.

CONCLUSIONS

The incidence of type II perforation was dependent on the degree of difficulty of ERCP. The treatment of type II perforation with a covered SEMS can significantly reduce the incidence of retroperitoneal abscess and shorten the hospital stay, with better results than surgical and conservative treatments.

Reno-Duodenal Fistula as a Complication of Staghorn Stones and Renal Pelvis Tumor: A Case Presentation

Reno alimentary fistula, a rare illness characterized by improper connection between the kidney and digestive tract, can lead to urinary tract infections, abscesses, and severe sepsis. It can also be caused by various factors such as chronic infections, malignancy, cryoablation, or abdominal surgical procedures. We present a case of a 60-year-old man with bilateral staghorn stones who was diagnosed with reno-duodenal fistula and underwent a right simple nephrectomy and fistula closure. The histopathology revealed a well-differentiated squamous cell carcinoma that originated from the renal pelvis.

Shahwan S, Al-qaoud D, Fataftah J. ERCP-induced perforation: review and revisit after half a century

Background

Endoscopic retrograde cholangiopancreatography (ERCP) is an invasive procedure. We aimed to investigate ERCP-induced perforations at our institution and conduct a comprehensive review of literature on ERCP-induced perforations (EIP) since the introduction of this procedure as a therapeutic intervention.

Methods

This was a case-control study, in which charts of all patients diagnosed with ERCP-induced duodenal perforation were reviewed and compared to a control group without perforation. Patient's sociodemographic and clinical data, including ERCP procedure-related data, were gathered.

Results

A total of 996 ERCP procedures were performed; only 13 patients proved to have EIP. Obstructive jaundice was the most common indication for ERCP. The main predisposing factor was difficult cannulation (P = 0.003). In total, five patients required surgical treatment; the majority of them had type I perforation, whereas type IV was the most common in patients who were treated conservatively. The overall mortality rate was 15%, the surgical group had a slightly higher mortality rate.

Conclusions

Fifty years after the introduction of ERCP for therapy, it remains an invasive procedure that carries significant morbidity and mortality, even in skilled hands or at high- volume units. Conservative management of perforation yields favorable outcomes in selected patients.

ERCP-related adverse events: incidence, mechanisms, risk factors, prevention, and management

INTRODUCTION

Endoscopic retrograde cholangiopancreatography (ERCP) is a commonly performed procedure for pancreaticobiliary disease. While ERCP is highly effective, it is also associated with the highest adverse event (AE) rates of all commonly performed endoscopic procedures. Thus, it is critical that endoscopists and caregivers of patients undergoing ERCP have clear understandings of ERCP-related AEs.

AREAS COVERED

This narrative review provides a comprehensive overview of the available evidence on ERCP-related AEs. For the purposes of this review, we subdivide the presentation of each ERCP-related AE according to the following clinically relevant domains: definitions and incidence, proposed mechanisms, risk factors, prevention, and recognition and management. The evidence informing this review was derived in part from a search of the electronic databases PubMed, Embase, and Cochrane, performed on 1 May 20231 May 2023.

EXPERT OPINION

Knowledge of ERCP-related AEs is critical not only given potential improvements in peri-procedural quality and related care that can ensue but also given the importance of reviewing these considerations with patients during informed consent. The ERCP community and researchers should aim to apply standardized definitions of AEs. Evidence-based knowledge of ERCP risk factors should inform patient care decisions during training and beyond.

Complex duodenal fistulae: a surgical nightmare

INTRODUCTION

A common feature of external duodenal fistulae is the devastating effect of the duodenal content rich in bile and pancreatic juice on nearby tissues with therapy-resistant local and systemic complications. This study analyzes the results of different management options with emphasis on successful fistula closure rates.

METHODS

A retrospective single academic center study of adult patients treated for complex duodenal fistulas over a 17-year period with descriptive and univariate analyses was performed.

RESULTS

Fifty patients were identified. First line treatment was surgical in 38 (76%) cases and consisted of resuture or resection with anastomosis combined with duodenal decompression and periduodenal drainage in 36 cases, rectus muscle patch, and surgical decompression with T-tube in one each. Fistula closure rate was 29/38 (76%). In 12 cases, the initial management was nonoperative with or without percutaneous drainage. The fistula was closed without surgery in 5/6 patients (1 patient died with persistent fistula). Among the remaining 6 patients eventually operated, fistula closure was achieved in 4 cases. There was no difference in successful fistula closure rates among initially operatively versus nonoperatively managed patients (29/38 vs. 9/12, p = 1.000). However, when considering eventually failed nonoperative management in 7/12 patients, there was a significant difference in the fistula closure rate (29/38 vs. 5/12, p = 0.036). The overall in-hospital mortality rate was 20/50 (40%).

CONCLUSIONS

Surgical closure combined with duodenal decompression in complex duodenal leaks offers the best chance of successful outcome. In selected cases, nonoperative management can be tried, accepting that some patients may require surgery later.

The Efficacy of Over-the-Scope Clip Closure for Gastrointestinal Iatrogenic Perforation During Endoscopic Ultrasound and Endoscopic Retrograde Cholangiopancreatography for Pancreaticobiliary Diseases

BACKGROUND

Intestinal perforation is a severe adverse event during pancreaticobiliary endoscopy. The use of over-the-scope clip (OTSC) has recently increased; however, the efficacy of OTSC during pancreaticobiliary endoscopy has not been well studied.

AIMS

To evaluate the efficacy of OTSC for the closure of gastrointestinal iatrogenic perforation during pancreaticobiliary endoscopy.

PATIENTS AND METHODS

This was a retrospective multicenter cohort study conducted at 3 tertiary care centers. The inclusion criteria were patients who had gastrointestinal perforation during endoscopic procedures for pancreaticobiliary diseases and underwent perforation closure using OTSC. The primary outcome was the clinical success rate. Secondary outcomes were technical success rates, adverse event rates, and the duration until the start of oral intake after OTSC.

RESULTS

Ten patients were treated by OTSC from January 2013 to December 2017. In 2 out of 10, the perforations could not be closed completely. In the remaining 8, perforations were closed completely, but intestinal obstruction caused by OTSC occurred in 1 patient. The clinical success rate was 80% (8/10). The technical and adverse event rates were 80% (8/10) and 10% (1/10), respectively. A median resumption timing of oral intake was 5 days (range, 3 to 10 d).

CONCLUSION

OTSC is considered as effective management for perforations during pancreaticobiliary endoscopy, although careful consideration is required for the indication of OTSC.

Management of scope-induced type I duodenal perforations: Over-the-scope clip versus surgery

BACKGROUND

Scope-induced duodenal perforation is a life-threatening complication and surgery remains the standard of care. With the advent of over-the-scope clip (OTSC), scope-induced perforations are increasingly managed conservatively, though there is no study comparing this form of non-surgical treatment with surgery. We aimed to compare OTSC and surgery in the management of scope-induced perforation of the duodenum.

METHODS

We retrospectively collected data of scope-induced duodenal perforation patients. Perforations identified and treated within 24 h of procedure were analyzed. Factors analyzed were spectrum, etiology, baseline parameters, perforation size, outcome, comorbidities, and duration of hospital stay.

RESULTS

A total of 25 patients had type I duodenal perforations, out of whom five were excluded due to delayed diagnosis and treatment. Of the twenty, eight were treated with OTSC placement while the rest underwent surgery. Age was comparable and the majority were females. Baseline parameters and comorbidities were similar in both the groups. The median size of perforation was 1.5 cm in both the OTSC group and the surgical group. All patients were treated with standard of care according to institutional protocols. Patients in the OTSC group were started orally after 48 h of OTSC placement, while in the surgery group median time to oral intake was 7 days. Two patients in the surgical group died while there was no mortality in the OTSC group (p = 0.48). Median hospital stay was shorter in the OTSC group (2 days vs. 22 days, p = 0.003).

CONCLUSIONS

OTSC is a feasible and better option in type I duodenal perforations with a shorter hospital stay.

Intestinal perforations after endoscopic retrograde cholangiopancreatography in the USA: a 16-year study using the National Inpatient Sample

BACKGROUND

Intestinal perforation is a rare but feared complication of ERCP. In this study, we identify patient and hospital factors for ERCP related intestinal perforation using a large national database. We also examine the effects of intestinal perforations on hospital outcomes.

METHODS

Data were obtained from the National Inpatient Sample, the largest publicly available inpatient care database in the United States. ICD-9-CM procedure codes for all ERCP procedures conducted between 1998 and 2013. Our primary outcome of interest was the incidence of intestinal perforations after ERCP. Secondary outcomes of interest included hospital length of stay and inpatient mortality.

RESULTS

A total of 392,336 ERCP procedures were performed over the study period, met our inclusion criteria, and were analyzed. Mean age of sample was 59 years and just over 60% were females. Low volume hospitals accounted for over 85% of ERCPs. Intestinal perforations occurred at a rate of 1.2 per 1000 ERCP procedures. Patient's age was the only patient-related factor significantly associated with perforation. (OR: 1.016; 95% CI 1.009-1.025). For hospitals, teaching status was the only hospital related factor associated with intestinal perforation after ERCP (OR: 1.56; 95% CI 1.28-1.91). Length of stay was much longer in patients with ERCP related perforations and mortality risk was ten times higher in the same cohort.

CONCLUSIONS

Patients who have ERCP related perforations have longer hospital stays and have a higher mortality risk. Older patients and those who had ERCP in teaching hospitals are at a higher risk of perforation.

Endoscopic Treatment of Endoscopic Retrograde Cholangiopancreatography-Related Duodenal Perforations

BACKGROUND

Endoscopic retrograde cholangiopancreatography (ERCP)-related duodenal perforation is a rare complication associated with significant morbidity and mortality. This study evaluated endoscopic management experience and outcomes of ERCP-related duodenal perforations.

MATERIALS AND METHODS

Between March 2005 and March 2017, a total of 19,468 ERCP procedures were performed in three endoscopy units of three hospitals in China. Diagnoses, management, and outcomes were identified and retrospectively reviewed in 58 of these patients.

RESULTS

According to the classification system, 58 patients included 8 with type I, 44 with type II, 4 with type III, and 2 with type IV perforation. Of type I perforations, 7 patients underwent endoscopic closure with endoclips, and 1 patient was treated with surgical repair. Of type II perforations, 11 patients were actively managed using the fully covered self-expandable metallic stents (SEMS) to seal the perforation, and 33 patients were passively managed using nose-biliary drainage, in which 13 cases had retroperitoneal abscess formation and were successfully treated by abdominal computed tomography (CT)-guided percutaneous external drainage, but 1 patient died due to sepsis. One patient with type III perforation (pancreatic duct perforation) underwent endoscopic pancreatic duct stent placement after surgery failure. The mean hospital stay of 11 cases with type II perforation treated actively by endoscopy (26.5 ± 3.3 days) was lower compared with 33 cases who received passive conservative treatment (34.6 ± 3.9 days).

CONCLUSION

Many (especially type I and II) ERCP-related duodenal perforations can be successfully treated with endoscopic management. Active endoscopic therapy may be better than passive conservative treatment for type II perforations.

Management of horizontal duodenal perforation: a report of three cases and review of literature

Background

Perforation of the horizontal duodenum is very rare due to the presence in retroperitoneal space. It depicts an unusual clinical picture and is difficult to diagnose, leading to increased morbidity and mortality. The treatment strategies are usually varied and based on small series of cases, literature reviews, and expert opinions.

Case presentation

Here, we presented three cases of horizontal duodenal perforation in three different clinical processes. The first case, a 30-year-old male patient, presented with abdominal pain and hematemesis after experiencing a physical assault on the previous day. Computed tomography (CT) scan showed rupture of the horizontal duodenum. It was repaired by side-to-side duodenojejunostomy. Postoperatively, he had anastomotic leakage, disseminated intravascular coagulation, and pulmonary failure and recovered after a long hospital stay. The second case, an 81-year-old female, had duodenal perforation with endoscopic coagulation of the bleeding diverticulum. Segmental resection of the duodenum and side-to-side duodenojejunostomy were performed. Postoperatively, there was slight anastomotic leakage, but surgical intervention was not needed. The third case, an 89-year-old female, was a patient with obstructive jaundice due to pancreas head carcinoma, who developed perforation of the horizontal duodenum during endoscopic retrograde cholangiopancreatography (ERCP). After unsuccessful conservative management, duodenojejunostomy at the perforated site and gastric bypass were performed. The postoperative course was uneventful.

Conclusion

Early suspicion and investigation is necessary for cases of abdominal injuries. CT scan is the investigation of choice. The management options should be based on the clinical condition of the patient, comorbidities, surgical expertise, existing guidelines, and available resources.

Duodenal perforation following esophagogastroduodenoscopy (EGD) with cautery and epinephrine injection for peptic ulcer disease: An interesting case of nonoperative management in the medical intensive care unit (MICU)

INTRODUCTION

The utilization of esophagogastroduodenoscopy (EGD) and related procedures continues to rise. Due to this increase in utilization is an inevitable rise in serious complications such as hemorrhage and perforation. One understudied and dreaded complication of EGD causing significant morbidity and mortality is duodenal perforation.

PRESENTATION OF CASE

We present the case of a 63-year-old male who presented to our institution's emergency room with dyspepsia, melanic stools, tachycardia, and hypotension. Initial laboratory evaluation was significant for severe anemia, lactic acidosis, and acute kidney injury, while CT scan of the abdomen pelvis did not suggest retroperitoneal hematoma or bowel perforation. An emergent EGD was performed which showed multiple bleeding duodenal ulcers that were cauterized and injected with epinephrine. Post-procedure the patient developed worsening abdominal pain, distension, diaphoresis, and tachypnea, requiring emergent intubation. A CT scan of the abdomen and pelvis with oral contrast confirmed pneumoperitoneum and duodenal perforation.

DISCUSSION

Due to the patient's hemodynamic instability and multiple comorbidities, he was treated non-operatively with strict bowel rest and intravenous antibiotics. The patient ultimately had a 19-day hospital course complicated by renal failure requiring hemodialysis and an ischemic limb necessitating above knee amputation.

CONCLUSION

This case describes an unsuccessful attempt at nonoperative management of duodenal perforation following EGD.
