Buried bumper syndrome in percutaneous endoscopic gastrostomy with a jejunal extension tube in patients undergoing levodopa-carbidopa intestinal gel treatment.

BACKGROUND: Levodopa-carbidopa intestinal gel (LCIG) treatment is an effective Parkinson's disease (PD) treatment that requires percutaneous endoscopic gastrostomy with a jejunal extension tube (PEG-J). Buried bumper syndrome (BBS) is an uncommon but significant complication of PEG-J for LCIG. Case presentation A 71-year-old man had been undergoing LCIG therapy for PD since a PEG-J was implemented at our department two years previously. He presented with appetite loss. Computed tomography showed that the gastrostomy bumper was buried in the gastric wall. The patient was surgically treated with the simultaneous removal and replacement of PEG-J. Postoperative gastrocutaneous fistula occurred, which was conservatively treated. CONCLUSIONS: Notably, patients and medical staff should be aware that patients with PD on LCIG treatment have a high risk of BBS in PEG-J and that there might be some patients with latent BBS. When simultaneous removal and replacement surgery is performed, establishing a new route at the stomach and abdominal wall is recommended.

Percutaneous Endoscopic Gastrostomy. Is It Truly Harmless?

Percutaneous endoscopic gastrostomy (PEG) is performed quite frequently in our environment. In general, its complications are few and mostly minor; however, there is a 2.4% incidence of significant complications, particularly abnormal displacement of the internal bumper of the gastrostomy, known as buried bumper syndrome (BBS). Serious infections, tears, and fistulas can also occur. This work illustrates five cases of severe complications of PEG.

La gastrostomía endoscópica percutánea es un procedimiento realizado con alta frecuencia en nuestro medio; por lo general, sus complicaciones son escasas y en su mayoría menores, pero hay un 2,4% de incidencia de complicaciones mayores, en especial el desplazamiento anormal del disco interno de la gastrostomía, conocido como síndrome de Buried Bumper (SBB), y también se pueden presentar infecciones graves, desgarros y fístulas. En este trabajo se presentan 5 casos en los que se ilustran complicaciones graves de la gastrostomía endoscópica percutánea.

Acute Buried Bumper Syndrome: A Case Report.

Buried bumper syndrome (BBS) is a rare but severe complication of percutaneous endoscopic gastrostomy (PEG) tube feeding. Patients with BBS lose PEG tube patency and may experience peristomal pain, content leaks, or peritonitis. An early diagnosis can avert further complications. BBS is a clinical diagnosis, but an abdominal computerized tomography scan or upper endoscopy is needed to confirm the diagnosis. BBS is a long-term complication of PEG tube feeding, and cases of acute onset are scant in the literature. We report a unique case of a 65-year-old female with a history of stroke who developed BBS five weeks after PEG tube placement.

Buried bumper syndrome: A critical analysis of endoscopic release techniques.

Buried bumper syndrome (BBS) is the situation in which the internal bumper of the gastrostomy tube, due to prolonged compression of the tissues between the external and the internal bumper, migrates from the gastric lumen into the gastric wall or further, into the tract outside the gastric lumen, ending up anywhere between the stomach mucosa and the surface of the skin. This restricts liquid food from entering the stomach, since the internal opening is obstructed by gastric mucosal overgrowth. We performed a comprehensive search of the PubMed literature to retrieve all the case-reports and case-series referring to BBS and its management, after which we focused on the endoscopic techniques for releasing the internal bumper to re-establish the functionality of the tube. From the "push" and the "push and pull T" techniques to the most sophisticated-using high tech instruments, all 10 published techniques have been critically analysed and the pros and cons presented, in an effort to optimize the criteria of choice based on maximum efficacy and safety.

Endoscopic management of buried bumper syndrome using the Balloon Dilation Pull (BDP) technique: a multicenter analysis.

Background and study aims: Buried bumper syndrome (BBS) may complicate percutaneous endoscopic gastrostomy placement. In these patients, endoscopic treatment ought to be considered. Various approaches have been published, ranging from dissectionbased techniques to novel dedicated devices, although the evidence supporting the use of the Balloon Dilation Pull (BDP) technique has been limited to single case reports. The aim of this paper is to assess the feasibility, efficacy and safety of the systematic use of the BDPtechnique for the endoscopic treatment of BBS. Patients and methods: We performed a retrospective multicenter analysis of prospectively collected data from all patients treated with the BDP-technique between January 2011 and November 2021. Results: In total, 26 patients were identified (median age 72 (SD ± 13) years, 74% male, 84.6% underlying neurological disease). Technical success was achieved in 92.3%, with a median procedure time of 17.5 minutes (range 5-27). Adverse events were identified in 3.8% of patients (N=1, aspiration, ASGE lexicon severity grade: moderate). Conclusions: Our experience suggests that the BDP-technique is highly efficacious and safe, using accessories readily available in every endoscopic unit. Given the limited procedure time and tools required, this procedure has the potential to further optimize patient care in the context of BBS.

Nationwide Survey for Pediatric Gastrostomy Tube Placement in Korea.

BACKGROUND: Various methods have been implemented for pediatric gastrostomy tube placement. We aimed to investigate the performance status of pediatric gastrostomy in South Korea and to present indications and appropriate methods for domestic situations. METHODS: A survey was conducted among pediatric endoscopists who performed upper gastrointestinal endoscopy in Korea. The questionnaire consisted of 16 questions on gastrostomy performance status. RESULTS: Among the 48 institutions where the survey was applied, 36 (75%) responded. Of the 36 institutions, gastrostomy was performed in 31 (86.1%). The departments in which gastrostomy was performed were pediatrics at 26 institutions (81.3%), surgery at 24 institutions (75.0%), internal medicine at 9 institutions (28.1%), and radiology at 7 institutions (21.9%). There were 18 institutions (66.7%) using the pull method for percutaneous endoscopic gastrostomy (PEG) and nine institutions (33.3%) using the push method. When performing gastrostomies, fundoplication procedures were performed in 19 institutions (61.3%), if deemed necessary. However, 12 institutions (38.7%) answered that gastrostomy was always implemented alone. Complications after gastrostomy included buried bumper syndrome, wound infection, leakage, tube migration, and incorrect opening site in the stomach, but the number of cases with complications was very small. CONCLUSION: In Korea, a pediatric gastrostomy is implemented in various ways depending on the institution. Clinicians are concerned about choosing the most effective methods with fewer complications after the procedure. In our study, we reported only a few complications. Korea has good accessibility for pediatric gastrointestinal endoscopy, and this survey showed that it is a safe procedure that can be considered initially in pediatric gastrostomy. This study is expected to help to create optimal pediatric PEG guidelines in Korea.

Buried bumper syndrome: A late complication of PEG tube insertion.

The identification of BBS is crucial to avoid serious complications including sepsis and peritonitis. The diagnosis can be made clinically or from endoscopy. The exact site of the migrated PEG internal bumper can be demonstrated on imaging study.

Advances in endoscopic therapy using grasping-type scissors forceps (with video).

Endoscopic submucosal dissection (ESD) is a globally accepted minimally invasive therapy for early-stage gastrointestinal tract tumors. Although numerous electrosurgical knives have been developed for ESD, technical difficulties and high complication rates (bleeding and perforation) have limited their use worldwide. The grasping-type scissors forceps [clutch cutter (CC)] is the first forceps-type resection device developed with reference to hemostatic forceps. The aim was to allow easy and safe ESD throughout the gastrointestinal tract, as a biopsy technique, using one device. The CC can grasp the target tissue accurately and pull it away from the underlying muscle layer prior to energizing the tissue, for safe and effective incision and hemostasis during ESD. Reported clinical studies showed that ESD using the CC (ESD-CC) is a safe (perforation rate: 0%-3.6%; delayed bleeding rate: 0%-4.2%), technically efficient (en-bloc resection rate: 88.9%-100%), and single-device method for dissecting early-stage gastrointestinal tract tumors. The ESD-CC technique is simple and easy to learn because it can be completed simply by repeating the grasp, pull, and coagulate and/or incise actions using an electrosurgical current. The reported self-completion rate by non-experts was significantly better with the CC than with conventional knives (61.7% vs 24.5%, respectively; P < 0.001). Furthermore, the CC is used for other endoscopic therapies, such as endoscopic polypectomy for large pedunculated polyps, endoscopic myotomy for Zenker's diverticulum, endoscopic treatment of buried bumper syndrome, and endoscopic necrosectomy for wall-off pancreatic necrosis. The initial reports using CC for these therapies have shown favorable results. In this review, we describe the structural features of the CC, how to use the instrument, efficacies of ESD-CC, and other unique endoscopic therapies using the CC.

Buried bumper syndrome: prevention and management in the community.

Percutaneous endoscopic gastrostomy (PEG) is a well-established form of artificial nutrition. Buried bumper syndrome (BBS) is a rare but severe complication related to this type of feeding tube. BBS is described as when the internal bumper migrates into the stoma tract and/or the mucosa, and the inner lining of the stomach starts to grow around and over the internal bumper. It can result in pain, infection and the loss of the feeding tube as a port of entry for delivery of nutrition, hydration and medication into the stomach. When suspected, BBS requires urgent referral into specialist hospital services. It is somewhat preventable with appropriate aftercare; however, incidents do occur. The evidence and guidance on care of PEGs differs, and more data and research are needed into the incidence of BBS and what influences it. Access to appropriate nutrition support teams is essential to support patients and their caregivers with all aspects of enteral feeding.

Buried Bumper Syndrome: A common complication of levodopa intestinal infusion for Parkinson disease.

BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) is required for Levodopa/Carbidopa Intestinal Gel (LCIG) delivery in patients with advanced Parkinson's disease (PD) as well as for enteral feeding in a variety of neurological disorders. Buried Bumper Syndrome (BBS) is a serious complication of PEG. The frequency of BBS in patients receiving LCIG treatment has never been reported. OBJECTIVES: To compare the frequency of BBS in patients on LCIG treatment or on enteral feeding over the past 12 years and identify possible risk factors. METHODS: We reviewed prospectively recorded data from 2009 to 2020 on two case-series: LCIG-treated PD patients and non-PD patients on enteral nutrition. We identified all BBS incidences. Patients' characteristics, clinical manifestations, BBS management, possible risk factors and outcomes were analyzed. RESULTS: During the 12 years, 35 PD patients underwent PEG insertion for LCIG infusion, and 123 non-PD patients for nutritional support. There were eight cases of BBS in six PD patients (17.1%). Six of them were effectively managed without treatment discontinuation. Of the enteral feeding patients, only one developed BBS (0.8%) (p < 0.001). We identified inappropriate PEG site aftercare, weight gain, early onset PD, longer survival, treatment duration, dementia and PEG system design as potential risk factors for BBS development. CONCLUSIONS: BBS occurs more frequently in LCIG patients than in patients receiving enteral feeding. If detected early, it can be successfully managed, and serious sequalae or treatment discontinuation can be avoided. Regular endoscopic follow-up visits of LCIG-treated patients and increased awareness in patients and clinicians are recommended.

May chronic cough in chronic obstructive pulmonary disease be a contraindication of Percutaneous Endoscopic Gastrostomy placement: a case report.

BACKGROUND: Percutaneous Endoscopic Gastrostomy (PEG) can involve some complications, despite the good safety of its track record. The Buried Bumper Syndrome (BBS) is a rare, late and dangerous complication that consists in the erosion of the internal bumper through the gastric wall. Case presentation We report the development of BBS in a man with chronic obstructive pulmonary disease (COPD) who had a persistent chronic cough which was prevalently but not solely in the morning and required placement of a PEG tube for continuous infusion of Levodopa/carbidopa intestinal gel for advanced Parkinson's disease. CONCLUSION: We believe that COPD with chronic cough while not representing an absolute contraindication to PEG placement, may potentially cause BBS and therefore an appropriate regimen of tube care by expert personnel is mandatory in this setting.

An Early Presentation of Buried Bumper Syndrome.

Percutaneous endoscopic gastrostomy (PEG) is a well-established and successful method of nutritional delivery. Complications, although rare, are divided into early or late. Buried bumper syndrome (BBS) is usually a late complication of PEG tube insertion and can cause many issues such as pressure necrosis, peritonitis, and septic shock. Endoscopic evaluation is the definitive diagnosis, and treatment depends on each patient and the degree of depth of disc migration. We present to you a case of buried bumper syndrome in a 66-year-old female that was initially thought to be complicated with peritonitis, and surprisingly occurring only one week after initial PEG tube placement.

Early Buried Bumper Syndrome: A Rare Complication of Percutaneous Endoscopic Gastrostomy Tube Placement.

Early buried bumper syndrome (BBS) is a rare complication of percutaneous endoscopic gastrostomy (PEG) tube placement where the internal bolster gets "buried" in the gastrocutaneous fistulous tract. BBS is usually a late complication with onset > four weeks of PEG placement. We present a case of early BBS presenting at day 17 after PEG tube placement where the internal bolster got embedded in the subcutaneous fat just outside the gastric wall. The patient underwent urgent endoscopic removal of the buried bumper with the simple external traction, followed by the successful placement of a new tube through the same tract. Early diagnosis and prompt management are of paramount importance to avoid an ominous outcome.

Early Recognition and Diagnosis of Buried Bumper Syndrome: A Report of Three Cases.

Buried bumper syndrome (BBS) was described as a complication of percutaneous endoscopic gastrostomy (PEG) that occurs when the internal stump of the probe migrates and is located between the gastric wall and the skin. The increase of compression between the internal stump and the external stump of the gastrostomy tube causes pain and the inability to feed. We present the cases of three patients with BBS managed by the metabolic and nutritional support department. These cases intend to illustrate one of the less frequent complications of PEG, clinical presentation, risk factors, diagnosis, and especially clinical management. Although there are no defined gold standards for its management, the most important points in the management of this condition are early recognition, recommendations to avoid ischemic process at the moment of the insertion of the tube, specific care of the gastrostomy tube, and a periodic nutrition evaluation to avoid overweight, which causes traction and excessive pressure in the gastric wall. It is important for physicians to be aware of the recommendations to prevent BBS and its complications, especially in patients in whom communication can be difficult secondary to their pathologies and comorbidities.

Delayed Diagnosis of Buried Bumper Syndrome When Only the Jejunostomy Extension is Used in a Percutaneous Endoscopic Gastrostomy-jejunostomy Levodopa-carbidopa Intestinal Gel Delivery System.

Direct intrajejunal levodopa-carbidopa intestinal gel (LCIG) administered through a percutaneous endoscopic gastrostomy (PEG) with a jejunal extension tube (PEG-J) is an FDA-approved modality for treatment of patients with advanced Parkinson's disease (PD). Buried bumper syndrome (BBS) is a rare complication associated with PEG tubes inserted for drug administration or enteral feeding. The syndrome is diagnosed endoscopically revealing burial of the internal bumper in the gastric wall, causing numerous serious complications. When only the J extension of a PEG-J is used to deliver medications, and the G tube is not utilized, a delay in the diagnosis of BBS can occur. This is likely as the small caliber J extension tube remains patent and functional. We present the case of an elderly patient with advanced PD on LCIG therapy, who presented with a dislodged J-tube from a PEG-J system. Endoscopy revealed BBS that had likely developed prior to dislodgment of J-extension and despite a conservative approach, the internal bumper needed to be surgically extracted to prevent further complications.

Liver abscess as a rare complication of PEG.

INTRODUCTION: Percutaneous endoscopic gastrostomy (PEG) is one of the most effective methods of providing long-term enteral nutrition in patients with the impossibility of oral intake. Complications are relatively common. The most common is peristomal wound infection at the site of the insertion and leakage along the cannula. Lesscommon complications are colo-cutaneous fistulas and peritonitis. A very rare complication is liver abscess. CASE REPORT: The authors describe a case of a 51-year-old man with a hepatic abscess with inoperable pharyngeal carcinoma with PEG. The patient was admitted to hospital with a developing septic condition due to a liver abscess. The liverabscess resulted from the buried bumper syndrome of the PEG and subsequent complete dislocation of the bumper into the left liver lobe area.. This condition was treated by a surgical review with abscess drainage and the construction of classical gastrostomy. CONCLUSION: Buried bumper syndrome with its complications, such as a liver abscess is a relatively rare complication, but challenges both the diagnosis and therapy of the syndrome itself. Its management requires a close cooperation between a gastroenterologist and a surgeon. Early recognition and treatment can prevent the progression of the condition to sepsis or a septic shock, which can lead to death.
