Endoscopic treatment of duodenal fistula after incomplete closure of ERCP-related duodenal perforation

Endoscopic retrograde cholangiopancreatography(ERCP)is an important diagnostic and therapeutic modality for various pancreatic and biliary diseases.The most common ERCP-induced complication is pancreatitis,whereas hemorrhage,cholangitis,and perforation occur less frequently.Early recognition and prompt treatment of these complications may minimize the morbidity and mortality.One of the most serious complications is perforation.Although the incidence of duodenal perforation after ERCP has decreased to<1.0%,severe cases still require prolonged hospitalization and urgent surgical intervention,potentially leading to permanent disability or mortality.Surgery remains the mainstay treatment for perforations of the luminal organs of the gastrointestinal tract.However,evidence from case reports and case series support a beneficial role of endoscopic clipping in the closure of these defects.Duodenal fistulas are usually a result of sphincterotomies,perforated duodenal ulcers,or gastrectomy.Other causative factors include Crohn's disease,trauma,pancreatitis,and cancer.The majority of duodenal fistulas heal with nonoperative management.Those that fail to heal are best treated with gastrojejunostomy.Recently proposed endoscopic approaches for managing gastrointestinal leaks caused by fistulas include fibrin glue injection and positioning of endoclips.Our patient developed a secondary persistent duodenal fistula as a result of previous incomplete closure of duodenal perforation with hemoclips and an endoloop.The fistula was successfully repaired by additional clipping and fibrin glue injection.

Balloon dilation of congenital perforated duodenal web in newborns: Evaluation of short and long-term results

BACKGROUND Incomplete congenital duodenal obstruction(ICDO)is caused by a congenitally perforated duodenal web(CPDW).Currently,only six cases of balloon dilatation of the PDW in newborns have been described.AIM To present our experience of balloon dilatation of a perforated duodenal memb-rane in newborns with ICDO.METHODS Five newborns who underwent balloon dilatation of the CPDW along a prein-stalled guidewire between 2021 and 2023 were included.Nineteen newborns diagnosed with ICDO who underwent laparotomy were included in the control group.RESULTS In all cases,good anatomical and clinical results were obtained.In three cases,a follow-up study was conducted after 1 year.The average time to start enteral feeding per os was significantly earlier in the study group(4.4 d)than in the laparotomic group(21.2 days;P<0.0001).The time spent by patients in the intensive care unit and hospital after balloon dilatation was also significantly shorter.We determined the selection criteria for possible and effective CPDW balloon dilatation in newborns as follows:(1)Presence of dynamic radiographic signs of the passage of a radiopaque substance beyond the zone of narrowing or radiographic signs of pneumatisation of the duodenum and small bowel distal to the web;(2)presence of endoscopic signs of CPDW;(3)successful cannulation with a guidewire performed parallel to the endoscope,with holes in the congenital duodenal web;and(4)successful positioning of the balloon performed along a freestanding guidewire on the web.CONCLUSION Strictly following selection criteria for newborns with ICDO caused by CPDW ensures that endoscopic balloon dilatation using a pre-installed guidewire is safe and effective and shows good 1-year follow-up results.

Primary endoscopic approximation suture under cap-assisted endoscopy of an ERCP-induced duodenal perforation

Duodenal perforation during endoscopic retrograde cholangiopancreatography(ERCP) is a rare complication,but it has a relatively high mortality risk.Early diagnosis and prompt management are key factors for the successful treatment of ERCP-related perforation.The management of perforation can initially be conservative in cases resulting from sphincterotomy or guide wire trauma.However,the current standard treatment for duodenal free wall perforation is surgical repair.Recently,several case reports of endoscopic closure techniques using endoclips,endoloops,or fully covered metal stents have been described.We describe four cases of iatrogenic duodenal bulb or lateral wall perforation caused by the scope tip that occurred during ERCP in tertiary referral centers.All the cases were simply managed by endoclips under transparent capassisted endoscopy.Based on the available evidence and our experience,endoscopic closure was a safe and feasible method even for duodenoscope-induced perforations.Our results suggest that endoscopists may be more willing to use this treatment.

Endoscopic fibrin sealant closure of duodenal perforation after endoscopic retrograde cholangiopancreatography

Traditionally, perivaterian duodenal perforation can be managed conservatively or surgically. If a large volume of leakage results in fluid collection in the retroperitoneum, surgery may be necessary. Our case met the surgical indication for perivaterian duodenal perforation after endoscopic retrograde cholangiopancreatography(ERCP) with sphincterotomy and endoscopic papillary balloon dilatation. The patient developed a retroperitoneal abscess after the procedures, and a perivaterian perforation was suggested on computed tomography(CT). CT-guided abscess drainage was performed immediately. We unsuccessfully attempted to close the perforation with hemoclips initially. Subsequently, we used fibrin sealant(Tisseel) injection to occlude the perforation. Fibrin sealant injections have been previously used during endoscopy for wound closure and fistula repair. Based on our report, fibrin sealant injection can be considered as an alternative method for the treatment of ERCPrelated type Ⅱ perforations.

Migration of a biliary stent causing duodenal perforation and biliary peritonitis

Migration of endoscopically placed biliary stents is a well-recognized complication of endoscopic retrograde cholangiopancreatography. Less than 1% of migrated stents however cause intestinal perforation. We present a case of a migrated biliary stent that resulted in duodenal perforation and biliary peritonitis.

Small bowel perforation after duodenal stent migration:An interesting case of a rare complication

Duodenal stents are frequently used for palliating malignant gastric outlet obstruction.Successful stent placement relieves obstructive symptoms,is cost effective,and has a relatively low complication rate.However,enteral stents have the potential of migrating distally and rarely,even lead to bowel perforation.We present a rare case of a duodenal stent placed as a palliative measure for gastric outlet obstruction due to unresectable pancreatic cancer that migrated distally after a gastrojejunostomy resulting in small bowel perforation.

Closure of a persistent sphincterotomy-related duodenal perforation by placement of a covered self-expandable metallic biliary stent

Retroperitoneal duodenal perforation as a result of endoscopic biliary sphincterotomy is a rare complication, but it is associated with a relatively high mortality risk, if left untreated. Recently, several endoscopic techniques have been described to close a variety of perforations. In this case report, we describe the closure of a persistent sphincterotomy-related duodenal perforation by using a covered self-expandable metallic biliary (CEMB) stent. A 61-year-old Greek woman underwent an endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy for suspected choledo-cholithiasis, and a retroperitoneal duodenal perforation (sphincterotomy-related) occurred. Despite initial conservative management, the patient underwent a laparotomy and drainage of the retroperitoneal space. After that, a high volume duodenal fistula developed. Six weeks after the initial ERCP, the patient underwent a repeat endoscopy and placement of a CEMB stent with an indwelling nasobiliary drain. The fistula healed completely and the stent was removed two weeks later. We suggest the transient use of CEMB stents for the closure of sphincterotomy-related duodenal perforations. They can be placed either during the initial ERCP or even later if there is radiographic or clinical evidence that the leakage persists.

Treatment of a duodenal perforation secondary to an endoscopic sphincterotomy with clips

Perforation is one of the most serious complications of endoscopic sphincterotomy (ES) necessitating immediate surgical intervention. We present a case of successful management of such a complication with endoclipping. A85-year-old woman developed duodenal perforation after ES. The perforation was identified early and its closure was achieved using three metallic clips in a single session.There was no procedure-related morbidity or complications and our patient was discharged from hospital 10 d later.Endoclipping of duodenal perforation induced by ES is a safe, effective and alternative to surgery treatment.

Duodenal perforation after organophosphorus poisoning: A case report

BACKGROUND Organophosphorus poisoning(OP)is one of the common critical conditions in emergency departments in China,which is usually caused by suicide by taking oral drugs.Patients with severe OP have disturbance of consciousness,respiratory failure,toxic shock,gastrointestinal dysfunction,and so on.As far as we know,the perforation of the duodenum caused by OP has not been reported yet.CASE SUMMARY A 33-year-old male patient suffered from acute severe OP,associated with abdominal pain.Multiple computed tomography scans of the upper abdomen showed no evidence of intestinal perforation.However,retrograde digital subtraction angiography,performed via an abdominal drainage tube,revealed duodenal perforation.After conservative treatment,the symptoms eased and the patient was discharged from hospital.CONCLUSION Clinicians should pay close attention to gastrointestinal dysfunction and abdominal signs in patients with severe OP.If clinical manifestation and vital signs cannot be explained by common complications,stress duodenal ulcer or perforation should be highly suspected.

Effectiveness and safety of over-the-scope clip in closing perforations after duodenal surgery

BACKGROUND Endoscopic resection of duodenal subepithelial lesions(SELs)is a difficult procedure with a high risk of perforation.At present,dealing with perforation after endoscopic resection of duodenal SELs is still considered a great challenge.AIM To evaluate the effectiveness and safety of an over-the-scope clip(OTSC)in the treatment of perforation post-endoscopic resection of duodenal SELs.METHODS From May 2015 to November 2019,18 patients with perforation following endoscopic resection of duodenal SELs were treated with OTSCs.Data comprising the rate of complete resection,closure of intraprocedural perforation,delayed bleeding,delayed perforation,and postoperative infection were extracted.RESULTS The rate of complete removal of duodenal SELs and successful closure of the perforation was 100%.The median perforation size was 1 cm in diameter.Seventeen patients had minor intraoperative bleeding,while the remaining 1 patient had considerable amount of bleeding during the procedure.Seven patients had postoperative abdominal infections,of which 1 patient developed an abscess in the right iliac fossa and another patient developed septic shock.All 18 patients recovered and were discharged.No delayed bleeding or perforation was reported.The mean time taken to resume normal diet after the procedure was 6.5 d.The mean postoperative hospital stay was 9.5 d.No residual or recurrent lesions were detected during the follow-up period(15-66 mo).CONCLUSION Closing a perforation after endoscopic resection of duodenal SELs with OTSCs seems to be an effective and reasonably safe therapeutic method.

Perforations of Gastro-Duodenal Ulcers in the Surgery Department “A” at the University Hospital Point G Bamako

The purpose of this study was to investigate the clinical and therapeutic aspects of peritonitis by perforation of gastric and duodenal ulcer. This was a retrospective and descriptive study over 8 years (2010-2018) which allowed to collect 54 cases of peptic ulcer. Included in the study were all patients with confirmed gastroduodenal perforation on histology or laparotomy. We collected 54 cases of peptic ulcer perforated s. The age group of 30 - 49 years was the majority. The male sex was dominant with 90.7% of cases;the clinical picture was dominated by abdominal contracture associated with pain in 74.07% of cases. X-ray of the abdomen without preparation (AWP) revealed in 87.03% of cases of pneumoperitoneum. The perforation was in 68.52% of cases on the gastric antrum and in 31.48% on the duodenum. The surgical procedure used was the bank of excision, and a suture reinforcement epiploic in 68.52% of cases, a simple suture made in 31.48% of cases, the disease was marked by a fistula (1.90%) and mortality was 5.55% of cases. The gastroduodenal ulcer perforation is potentially serious and responsible peritonitis whose surgical treatment involves the peritoneal toilet and sutures the puncture.

Colonic perforation with duodenal-colic fistula formation by a biliary stent in a liver transplant recipient

Endoscopic retrograde cholangio-pancreatography (ERCP) is increasing utilized in the setting of liver transplantation for a number of post-operative related biliary issues. Although ERCP represents an excellent technology, it is not without attendant risk including sepsis, bleeding and perforation. In this case report, the first of its kind, is described the occurrence of a migrated biliary stent induced duodenal-colic fistula formation in a liver transplantation patient who had required dual biliary stenting given post-operative biliary structuring. The placement of dual stents and their size are likely implicated in the cause of perforation. The enteric anatomy and the medical immunosuppression likely contributed to a delay in diagnosis and worse outcome.

Perforated duodenal diverticulum, a rare complication of a common pathology: A seven-patient case series

Duodenal diverticula (DD) are frequently encountered and are usually asymptomatic, with an incidence at autopsy of 22%. Perforation of DD is a rare complication (around 160 cases reported) with potentially dramatic consequences. However, little evidence regarding its treatment is available in the literature. The aim of this study was to review our experience of perforated DD, with a focus on surgical management. Between January 2001 and June 2011, all perforated DD were retrospectively reviewed at a single centre. Seven cases (5 women and 2 men; median age: 72.4 years old, rang: 48-91 years) were found. The median American Society of Anesthesiologists' score in this population was 3 (range: 3-4). The perforation was located in the second portion of duodenum (D2) in six patients and in the third portion (D3) in one patient. Six of these patients were treated surgically: five patients underwent DD resection with direct closure and one was treated by surgical drainage and laparostomy. One patient was treated conservatively. One patient died and one patient presented a leak that was successfully treated conservatively. The median hospital stay was 21.1 d (range: 15-30 d). Perforated DD is an uncommon presentation of a common pathology. Diverticular excision with direct closure seems to offer the best chance of survival and was associated with a low morbidity, even in fragile patients.

Conservative management of perforated duodenal diverticulum: A case report and review of the literature

Duodenal diverticula are a relatively common condition. They are asymptomatic, unless they become complicated, with perforation being the rarest but most severe complication. Surgical treatment is the most frequently performed approach. We report the case of a patient with a perforated duodenal diverticulum, which was diagnosed early and treated conservatively with antibiotics and percutaneous drainage of secondary retroperitoneal abscesses. We suggest this method could be an acceptable option for the management of similar cases, provided that the patient is in good general condition and without septic signs.

Perforated duodenal ulcer presenting with massive hematochezia in a 30-month-old child

Peptic ulcer disease is uncommon in children and rarely suspected as a cause of abdominal complaints in this age group; the diagnosis is therefore made almost exclusively when complications develop. Peptic ulcer disease is usually not considered in the differential diagnosis of pediatric patients. We present the case of a 30-month-old boy with duodenal perforation due to a peptic ulcer without a known etiology. The patient was admitted through the emergency department due to severe hematochezia and ongoing anemia; he presented with neither abdominal pain nor abdominal distension. There were no medical problems, and no drugs, such as corticosteroids or nonsteroidal anti-inflammatory drugs, had been prescribed or administered recently. We tried to control the active bleeding by medical treatment including arterial embolization, but the active bleeding was not controlled. Finally, an exploratory laparotomy was performed. A discrete anterior perforation with active bleeding of the duodenal wall was found. After the operation, there were no complications and the patient recovered fully.

Mediastinal emphysema in the context of perforated gastric ulcer

In the context of mediastinal emphysema/pneumomediastinum,the main aetiologies are associated with oesophageal perforation,lung pathology or post head and neck surgery related.The main way to differentiate the pathologies would be through Computed Tomographic Imaging of the Thorax and abdomen with oral and intravenous contrast in the context of triple phase imaging.The causes of pneumomediastinum should be differentiated between traumatic and non-traumatic.Oesophageal perforation(Boerhaave syndrome)is associated with Mackler’s triad in upto 50%of patients(severe retrosternal chest pain,pneumomediastinum,mediastinitis).Whereas in cases of lung pathology this can be associated with pneumothorax and pleural effusion.

Endoscopic pancreaticobiliary drainage with overlength stents to prevent delayed perforation after endoscopic papillectomy:A pilot study

BACKGROUND Endoscopic papillectomy(EP)is rapidly replacing traditional surgical resection and is a less invasive procedure for the treatment of duodenal papillary tumors in selected patients.With the expansion of indications,concerns regarding EP include not only technical difficulties,but also the risk of complications,especially delayed duodenal perforation.Delayed perforation after EP is a rare but fatal complication.Exposure of the artificial ulcer to bile and pancreatic juice is considered to be one of the causes of delayed perforation after EP.Draining bile and pancreatic juice away from the wound may help to prevent delayed perforation.AIM To evaluate the feasibility and safety of placing overlength biliary and pancreatic stents after EP.METHODS This is a single-center,retrospective study.Five patients with exposure or injury of the muscularis propria after EP were included.A 7-Fr overlength biliary stent and a 7-Fr overlength pancreatic stent,modified by an endoscopic nasobiliary drainage tube,were placed in the common bile duct and pancreatic duct,respectively,and the bile and pancreatic juice were drained to the proximal jejunum.RESULTS EP and overlength stents placement were technically feasible in all five patients(63±12 years),with an average operative time of 63.0±5.6 min.Of the five lesions(median size 20 mm,range 15-35 mm),four achieved en bloc excision and curative resection.The final histopathological diagnoses of the endoscopic specimen were one tubular adenoma with high-grade dysplasia(HGD),one tubulovillous adenoma with low-grade dysplasia,one hamartomatous polyp with HGD,one poorly differentiated adenocarcinoma and one atypical juvenile polyposis with tubulovillous adenoma,HGD and field cancerization invading the muscularis mucosae and submucosa.There were no stent-related complications,but one papillectomy-related complication(mild acute pancreatitis)occurred without any episodes of bleeding,perforation,cholangitis or late-onset duct stenosis.CONCLUSION For patients with exposure or injury of the muscularis propria after EP,the placement of overlength biliary and pancreatic stents is a feasible and useful technique to prevent delayed perforation.

Clinical characteristics of peptic ulcer perforation in Korea

AIM To elucidate the epidemiological characteristics and associated risk factors of perforated peptic ulcer(PPU).METHODS We retrospectively reviewed medical records of patients who were diagnosed with benign PPU from 2010 through 2015 at 6 Hallym university-affiliated hospitals.RESULTS A total of 396 patients were identified with postoperative complication rate of 9.1% and mortality rate of 0.8%. Among 174(43.9%) patients who were examined for Helicobacter pylori(H. pylori) infection, 78(44.8%) patients were positive for H. pylori infection, 21(12.1%) were on non-steroidal anti-inflammatory drugs(NSAIDs) therapy, and 80(46%) patients were neither infected of H. pylori nor treated by any kinds of NSAIDs. Multivariate analysis indicated that older age(OR = 1.09, 95%CI: 1.04-1.16) and comorbidity(OR = 4.11, 95%CI: 1.03-16.48) were risk factors for NSAID-associated PPU compared with non-H. pylori, non-NSAID associated PPU and older age(OR = 1.04, 95%CI: 1.02-1.07) and alcohol consumption(OR = 2.08, 95%CI: 1.05-4.13) were risk factors for non-H. pylori, non-NSAID associated PPU compared with solely H. pylori positive PPU.CONCLUSION Elderly patients with comorbidities are associated with NSAIDs-associated PPU. Non-H. pylori, non-NSAID peptic ulcer is important etiology of PPU and alcohol consumption is associated risk factor.

ERCP术后十二指肠穿孔及其相关腹膜后感染诊治的研究进展

十二指肠穿孔是经内镜逆行胰胆管造影(endoscopic retrograde cholangiopancreatogra-phy,ERCP)术后偶发但严重的并发症。早期临床症状常难以与术后胰腺炎和胆管炎鉴别,诊断延迟可导致腹膜后感染;而腹膜后间隙组织疏松,感染容易沿腹膜后间隙扩散,血运较差且易形成脓肿,引起脓毒症和多器官功能衰竭,伴随着住院时间长和较高的病死率;有效地对其进行诊断和治疗,病人的预后可得到极大的改善。此文结合国内外文献综述ERCP术后十二指肠穿孔和相关的腹膜后感染的临床表现和治疗方法。

腹腔镜下穿孔修补术治疗中老年十二指肠溃疡合并胃穿孔的疗效及对胃肠动力的影响分析

目的分析中老年十二指肠溃疡合并胃穿孔采取腹腔镜下穿孔修补术治疗的临床效果及对胃肠动力的影响。方法78例中老年十二指肠溃疡合并胃穿孔患者作为观察对象,按照随机数字表法分为观察组(腹腔镜下穿孔修补术,39例)和对照组(常规手术,39例)。对比两组临床疗效、术中出血量、术后肛门排气时间、肠鸣音恢复时间、住院时间、并发症(切口感染、肠梗阻、腔隙感染)发生率及治疗前后Barthel指数、视觉模拟评分法(VAS)评分。结果观察组总有效率89.7%高于对照组的71.8%,差异明显(P<0.05)。治疗后,两组VAS评分低于治疗前,Barthel指数高于治疗前,且观察组VAS评分(1.69±0.15)分低于对照组的(3.45±0.12)分,Barthel指数(91.45±3.23)分高于对照组的(81.23±6.15)分(P<0.05)。观察组术后肛门排气时间(27.72±5.23)h、肠鸣音恢复时间(12.41±4.23)h、住院时间(5.23±0.23)d短于对照组的(42.39±3.53)h、(27.51±3.34)h、(10.88±1.22)d,术中出血量(42.62±3.23)ml少于对照组的(73.24±5.31)ml,差异明显(P<0.05)。观察组并发症发生率10.3%低于对照组的30.8%,差异明显(P<0.05)。结论中老年十二指肠溃疡合并胃穿孔采取腹腔镜下穿孔修补术治疗可明显提高治疗效果,较常规手术更能减轻术后疼痛感,同时还可促进胃肠功能恢复,降低手术后并发症发生率,值得推广。
