“Timing of percutaneous endoscopic gastrostomy tube placement in post-stroke patients does not impact mortality,complications,or outcomes”:Commentary

In this commentary,we summarize some of the key points of the original paper“Timing of percutaneous endoscopic gastrostomy tube placement in post-stroke patients does not impact mortality,complications,or outcomes”and offer support for the proposed results.Specifically,we address how early percutaneous endoscopic gastrostomy(PEG)tube placement may reduce hospital length of stay and costs.We also discuss topics related to the article including PEG weaning and post-stroke nutritional formulation.However,we note that concerns purported by previous studies that early PEG placement may worsen outcomes are not fully addressed,and further research is needed.

How far is the endoscopist to blame for a percutaneous endoscopic gastrostomy complication?

BACKGROUND Percutaneous endoscopic gastrostomy(PEG)is a well-established,minimally invasive,and easy to perform procedure for nutrition delivery,applied to individuals unable to swallow for various reasons.PEG has a high technical success rate of insertion between 95%and 100%in experienced hands,but varying complication rates ranging from 0.4%to 22.5%of cases.AIM To discuss the existing evidence of major procedural complications in PEG,mainly focusing on those that could probably have been avoided,had the endoscopist been more experienced,or less self-confident in relation to the basic safety rules for PEG performance.METHODS After a thorough research of the international literature of a period of more than 30 years of published“case reports”concerning such complications,we critically analyzed only those complications which were considered-after assessment by two experts in PEG performance working separately-to be directly related to a form of malpractice by the endoscopist.RESULTS Malpractice by the endoscopist were considered cases of:Gastrostomy tubes passed through the colon or though the left lateral liver lobe,bleeding after puncture injury of large vessels of the stomach or the peritoneum,peritonitis after viscera damage,and injuries of the esophagus,spleen,and pancreas.CONCLUSION For a safe PEG insertion,the overfilling of the stomach and small bowel with air should be avoided,the clinician should check thoroughly for the proper trans-illumination of the light source of the endoscope through the abdominal wall and ensure endoscopically visible imprint of finger palpation on the skin at the center of the site of maximum illumination,and finally,the physician should be more alert with obese patients and those with previous abdominal surgery.

Percutaneous endoscopic gastrostomy and jejunostomy:Indications and techniques

Nutritional support is essential in patients who have a limited capability to maintain their body weight.Therefore,oral feeding is the main approach for such patients.When physiological nutrition is not possible,positioning of a nasogastric,nasojejunal tube,or other percutaneous devices may be feasible alternatives.Creating a percutaneous endoscopic gastrostomy(PEG)is a suitable option to be evaluated for patients that need nutritional support for more than 4 wk.Many diseases require nutritional support by PEG,with neurological,oncological,and catabolic diseases being the most common.PEG can be performed endoscopically by various techniques,radiologically or surgically,with different outcomes and related adverse events(AEs).Moreover,some patients that need a PEG placement are fragile and are unable to express their will or sign a written informed consent.These conditions highlight many ethical problems that become difficult to manage as treatment progresses.The aim of this manuscript is to review all current endoscopic techniques for percutaneous access,their indications,postprocedural follow-up,and AEs.

Buried bumper syndrome:A complication of percutaneousendoscopic gastrostomy

Percutaneous endoscopic gastrostomy(PEG) is a widely used method of nutrition delivery for patients with longterm insufficiency of oral intake. The PEG complication rate varies from 0.4% to 22.5% of cases, with minor complications being three times more frequent. Buried bumper syndrome(BBS) is a severe complication of this method, in which the internal fixation device migrates alongside the tract of the stoma outside the stomach. Excessive compression of tissue between the external and internal fixation device of the gastrostomy tube is considered the main etiological factor leading to BBS. Incidence of BBS is estimated at around 1%(0.3%-2.4%). Inability to insert, loss of patency and leakage around the PEG tube are considered to be a typical symptomatic triad. Gastroscopy is indicated in all cases in which BBS is suspected. The depth of disc migration in relation to the lamina muscularis propria of the stomach is critical for further therapy and can be estimated by endoscopic or transabdominal ultrasound. BBS can be complicated by gastrointestinal bleeding, perforation, peritonitis, intra-abdominal and abdominal wall abscesses, or phlegmon, and these complications can lead to fatal outcomes. The most important preventive measure is adequate positioning of the external bolster. A conservative approach should be applied only in patients with high operative risk and dismal prognosis. Choice of the method of release is based on the type of the PEG set and depth of disc migration. A disc retained inside the stomach and completely covered by the overgrowing tissue can be released using some type of endoscopic dissection technique(needle knife, argon plasma coagulation, or papillotome through the cannula). Proper patient selection and dissection of the overgrowing tissue are the major determinants for successful endoscopic therapy. A disc localized out of the stomach(lamina muscularis propria) should be treated by a surgeon.

Laparoscopy-assisted percutaneous endoscopic gastrostomy enables enteral nutrition even in patients with distorted anatomy

AIM:To analyzed whether laparoscopy-assisted percutaneous endoscopic gastrostomy(PEG)could be a valuable option for patients with complicated anatomy.METHODS:A retrospective analysis of twelve patients(seven females,five males;six children,six young adults;mean age 19.2 years)with cerebral palsy,spastic quadriparesis,severe kyphoscoliosis and interposed organs and who required enteral nutrition(EN)due to starvation was performed.For all patients,standard PEG placement was impossible due to distorted anatomy.All the patients qualified for the laparoscopyassisted PEG procedure.RESULTS:In all twelve patients,the laparoscopy-assisted PEG was successful,and EN was introduced four to six hours after the PEG placement.There were no complications in the perioperative period,either technical or metabolic.All the patients were discharged from the hospital and were then effectively fed using bolus methods.CONCLUSION:Laparoscopy-assisted PEG should become the method of choice for gastrostomy tube placement and subsequent EN if PEG placement cannot be performed safely.

Effect of percutaneous endoscopic gastrostomy on gastroesophageal reflux in mechanically-ventilated patients

AIM： To investigate the effect of percutaneous endoscopic gastrostomy （PEG） on gastroesophageal reflux （GER） in mechanically-ventilated patients. METHODS ： In a prospective, randomized, controlled study 36 patients with recurrent or persistent ventilatorassociated pneumonia （VAP） and GER 〉 6% were divided into PEG group （n=16） or non-PEG group （n = 20）. Another 11 ventilated patients without reflux （GER 〈 3%） served as control group. Esophageal pH-metry was performed by the ＂pull through＂ method at baseline, 2 and 7 d after PEG. Patients were strictly followed up for semi-recumbent position and control of gastric nutrient residue. RESULTS： A significant decrease of median （range） reflux was observed in PEG group from 7.8 （6.2-15.6） at baseline to 2.7 （0-10.4） on d 7 post-gastrostomy （P 〈 0.01）, while the reflux increased from 9 （6.2-22） to 10.8 （6.3-36.6） （P〈 0.01） in non-PEG group. A significant correlation between GER （%） and the stay of nasogastric tube was detected （r= 0.56, P〈 0.01）. CONCLUSION： Gastrostomy when combined with semi- recumbent position and absence of nutrient gastric residue reduces the gastroesophageal reflux in ventilated patients.

Percutaneous endoscopic gastrostomy—Too often?Too late?Who are the right patients for gastrostomy?

Percutaneous endoscopic gastrostomy is an established method to provide nutrition to patients with restricted oral uptake of fluids and calories.Here,we review the methods,indications and complications of this procedure.While gastrostomy can be safely and easily performed during gastroscopy,the right patients and timing for this intervention are not always chosen.Especially in patients with dementia,the indication for and timing of gastrostomies are often improper.In this patient group,clear data for enteral nutrition are lacking;however,some evidence suggests that patients with advanced dementia do not benefit,whereas patients with mild to moderate dementia might benefit from early enteral nutrition.Additionally,other patient groups with temporary or permanent restriction of oral uptake might be a useful target population for early enteral nutrition to maintain mobilization and muscle strength.We plead for a coordinated study program for these patient groups to identify suitable patients and the best timing for tube implantation.

Investigation and prediction of enteral nutrition problems after percutaneous endoscopic gastrostomy

AIM： To investigate and predict enteral nutrition problems after percutaneous endoscopic gastrostomy （PEG）. METHODS： We retrospectively analyzed data for 252 out of 285 patients who underwent PEG at our hospital from 1999 to 2008 after PEG were defined as： Enteral nutrition problems （1） patients who required ≥ 1 mo after surgery to switch to complete enteral nutrition, or who required additional parenteral alimentation continuously; or （2） patients who abandoned switching to enteral nutrition using the gastrostoma and employed other nutritional methods. We attempted to identify the predictors of problem cases by using a logistic regression analysis that examined the patients＇ backgrounds and the specific causes that led to their problems. RESULTS： Mean age of the patients was 75 years, and in general, their body weight was low and their overall condition was markedly poor. Blood testing revealed that patients tended to be anemic and malnourished. A total of 44 patients （17.5%） were diagnosed as having enteral nutrition problems after PEG. Major causes of the problems included pneumonia, acute enterocolitis （often Clostridium difficile-related）, paralytic ileus and biliary tract infection. A multivariate analysis identified the following independent predictors for problem cases： （1） enteral nutrition before gastrectomy （a risk reduction factor）; （2） presence of esophageal hiatal hernia; （3） past history of paralytic ileus; and （4） presence of chronic renal dysfunction. CONCLUSION： Enteral nutrition problems after PEG occurred at a comparatively high rate. Patient background analysis elucidated four predictive factors for the problem cases.

Survival of geriatric patients after percutaneous endoscopic gastrostomy in Japan

AIM: To examine the long term survival of geriatric patients treated with percutaneous endoscopic gastrostomy (PEG) in Japan. METHODS: We retrospectively included 46 Japanese community and tertiary hospitals to investigate 931 consecutive geriatric patients (≥ 65 years old) with swallowing difficulty and newly performed PEG between Jan 1st 2005 and Dec 31st 2008. We set death as an outcome and explored the associations among patient’s characteristics at PEG using log-rank tests and Cox proportional hazard models. RESULTS: Nine hundred and thirty one patients were followed up for a median of 468 d. A total of 502 deaths were observed (mortality 53%). However, 99%, 95%, 88%, 75% and 66% of 931 patients survived more than 7, 30, 60 d, a half year and one year, respectively. In addition, 50% and 25% of the patients survived 753 and 1647 d, respectively. Eight deaths were considered as PEG-related, and were associated with lower serum albumin levels (P = 0.002). On the other hand, among 28 surviving patients (6.5%), PEG was removed. In a multivariate hazard model, older age [hazard ratio (HR), 1.02; 95% confidence interval (CI), 1.00-1.03; P = 0.009], higher C-reactive protein (HR, 1.04; 95% CI: 1.01-1.07; P = 0.005), and higher blood urea nitrogen (HR, 1.01; 95% CI: 1.00-1.02; P = 0.003) were significant poor prognostic factors, whereas higher albumin (HR, 0.67; 95% CI: 0.52-0.85; P = 0.001), female gender (HR, 0.60; 95% CI: 0.48-0.75; P < 0.001) and no previous history of ischemic heart disease (HR, 0.69; 95% CI: 0.54-0.88, P = 0.003) were markedly better prognostic factors. CONCLUSION: These results suggest that more than half of geriatric patients with PEG may survive longer than 2 years. The analysis elucidated prognostic factors.

Percutaneous endoscopic gastrostomy tube replacement:A simple procedure?

Replacement of gastrostomy tube in patients under-going percutaneous endoscopic gastrostomy (PEG) is generally considered as a safe and simple procedure. However, it could be associated with serious complications, such as gastrocutaneous tract disruption and intraperitoneal tube placement, which may lead to chemical peritonitis and even death. When PEG tube needs a replacement (e.g., occlusion or breakage of the tube), clinicians must realize that the gastrocutaneous tract of PEG is more friable than that of surgical gastrostomy because there is no suture fixation between gastric wall and abdominal wall in PEG. In general, the tract of PEG begins to mature in 1-2 wk after placement and it is well formed in 4-6 wk. However, this process could take a longer period of time in some patients. Accordingly, this article describes three major principles of a safe PEG tube replacement: (1) good control of the replacement tube along the well-formed gastrocutaneous tract; (2) minimal insertion force during the replacement, and, most importantly; and (3) reliable methods for the confirmation of intragastric tube insertion. In addition, the management of patients with suspected intraperitoneal tube placement (e.g., patients having abdominal pain or signs of peritonitis immediately after PEG tube replacement or shortly after tube feeding was resumed) is discussed. If prompt investigation confirms the intraperitoneal tube placement, surgical intervention is usually required. This article also highlights the fact that each institute should have an optimal protocol for PEG tube replacement to prevent, or to minimize, such serious complications. Meanwhile, clinicians should be aware of these potential complications, particularly if there are any difficulties during the gastrostomy tube replacement.

Inhibitory effects of carbon dioxide insufflation on pneumoperitoneum and bowel distension after percutaneous endoscopic gastrostomy

AIM:To evaluate the inhibitory effects of carbon dioxide (CO2) insufflation on pneumoperitoneum and bowel distension after percutaneous endoscopic gastrostomy (PEG).METHODS:A total of 73 consecutive patients who were undergoing PEG were enrolled in our study.After eliminating 13 patients who fitted our exclusion criteria,60 patients were randomly assigned to either CO2 (30 patients) or air insufflation (30 patients) groups.PEG was performed by pull-through technique after threepoint fixation of the gastric wall to the abdominal wall using a gastropexy device.Arterial blood gas analysis was performed immediately before and after the procedure.Abdominal X-ray was performed at 10 min and at 24 h after PEG to assess the extent of bowel distension.Abdominal computed tomography was performed at 24 h after the procedure to detect the presence of pneumoperitoneum.The outcomes of PEG for 7 d postprocedure were also investigated.RESULTS:Among 30 patients each for the air and the CO2 groups,PEG could not be conducted in 2 patients of the CO2 group,thus they were excluded.Analyses of the remaining 58 patients showed that the patients' backgrounds were not significantly different between the two groups.The elevation values of arterial partial pressure of CO2 in the air group and the CO2 group were 2.67 mmHg and 3.32 mmHg,respectively (P = 0.408).The evaluation of bowel distension on abdominal X ray revealed a significant decrease of small bowel distension in the CO2 group compared to the air group (P < 0.001) at 10 min and 24 h after PEG,whereas there was no significant difference in large bowel distension between the two groups.Pneumoperitoneum was observed only in the air group but not in the CO2 group (P = 0.003).There were no obvious differences in the laboratory data and clinical outcomes after PEG between the two groups.CONCLUSION:There was no adverse event associated with CO2 insufflation.CO2 insufflation is considered to be safer and more comfortable for PEG patients because of the lower incidence of pneumoperitoneum and less distension of the small bowel.

Percutaneous endoscopic gastrostomy and gastrooesophageal reflux in neurologically impaired children

AIM:To investigate the effects of percutaneous endoscopic gastrostomy(PEG) feeding on gastro-oesophageal reflux(GOR) in a group of these children using combined intraluminal pH and multiple intraluminal impedance(pH/MII) . METHODS:Ten neurologically impaired children underwent 12 h combined pH/MII procedures at least 1 d before and at least 12 d after PEG placement. METHODS:Prior to PEG placement(pre-PEG) a total of 183 GOR episodes were detected,156(85.2%) were non-acidic.After PEG placement(post-PEG) a total of 355 episodes were detected,182(51.3%) were nonacidic.The total number of distal acid reflux events statistically significantly increased post-PEG placement(prePEG total 27,post-PEG total 173,P=0.028) and themean distal pH decreased by 1.1 units.The distal reflux index therefore also significantly increased post-PEG [pre-PEG 0.25(0-2) ,post-PEG 2.95(0-40) ].Average proximal pH was lower post-PEG but the within subject difference was not statistically significant(P=0.058) . Median number of non-acid GOR,average reflux height,total acid clearance time and total bolus clearance time were all lower pre-PEG,but not statistically significant. CONCLUSION:PEG placement increases GOR episodes in neurologically impaired children.

Novel endoscopic management of buried bumper syndrome in percutaneous endoscopic gastrostomy: The Olympus Hook Knife

Buried bumper syndrome(BBS) is an uncommon but serious complication of percutaneous endoscopic gastrostomy. It involves the internal fixation device, or "bumper", migrating into the gastric wall and subsequent mucosal overgrowth. We described a case series of four patients with BBS treated with a novel endoscopic technique using a Hook Knife between June 2016 and February 2017. The Hook Knife is a rotating L-shaped cutting wire designed for hooking tissue and pulling it away from the gastric wall towards the lumen. The technique was successful in all four cases with no complications. Each patient was discharged on the day of treatment. The Hook Knife is a manoeuvrable, safe and effective device for endoscopic removal of buried bumpers and could avoid surgery in a high risk group of patients. To our knowledge this technique has not been described previously. We suggest that this technique should be added to the treatment algorithms for managing BBS.

Bleeding risk with clopidogrel and percutaneous endoscopic gastrostomy

AIM To compare bleeding within 48 h in patients undergoing percutaneous endoscopic gastrostomy(PEG) with or without clopidogrel.METHODS After institutional review board approval, a retrospective study involving a single center was conducted on adult patients having PEG(1/08-1/14). Patients were divided into two groups: Clopidogrel group consisting of those patients taking clopidogrel within 5 d of PEG and the non-clopidogrel group including those patients not taking clopidogrel within 5 d of the PEG.RESULTS Three hundred and nineteen PEG patients were found. One hundred and sixty-eight males and 151 females with mean body mass index 28.47 ± 9.75 kg/m2 and mean age 65.03 ± 16.11 years were identified. Thirtythree patients were on clopidogrel prior to PEG with 286 patients not on clopidogrel. No patients in either group developed hematochezia, melena, or hematemesiswithin 48 h of percutaneous endoscopic gastrostomy(PEG). No statistical differences were observed between the two groups with 48 h for hemoglobin decrease of > 2 g/dL(2 vs 5 patients; P = 0.16), blood transfusions(2 vs 7 patients; P = 0.24), and repeat endoscopy for possible gastrointestinal bleeding(no patients in either group). CONCLUSION Based on the results, no significant post-procedure bleeding was observed in patients undergoing PEG with recent use of clopidogrel.

Percutaneous endoscopic gastrostomy under steadypressure automatically controlled endoscopy:First clinicalseries

AIM: To elucidate the safety of percutaneous endoscopic gastrostomy(PEG) under steady pressure automatically controlled endoscopy(SPACE) using carbon dioxide(CO_2).METHODS: Nine patients underwent PEG with a modified introducer method under conscious sedation. A T-tube was attached to the channel of an endoscope connected to an automatic surgical insufflator. The stomach was inflated under the SPACE system. The intragastric pressure was kept between 4-8 mmH g with a flow of CO_2 at 35 L/min. Median procedure time, intragastric pressure, median systolic blood pressure, partial pressure of CO_2, abdominal girth before and immediately after PEG, and free gas and small intestinal gas on abdominal X-ray before and after PEG were recorded. RESULTS: PEG was completed under stable pneumostomach in all patients, with a median procedural time of 22 min. Median intragastric pressure was 6.9 mmH g and median arterial CO_2 pressure before and after PEG was 42.1 and 45.5 Torr(NS). The median abdominal girth before and after PEG was 68.1 and 69.6 cm(NS). A mild free gas image after PEG was observed in two patients, and faint abdominal gas in the downstream bowel was documented in two patients.CONCLUSION: SPACE might enable standardized pneumostomach and modified introducer procedure of PEG.

Palliative percutaneous endoscopic gastrostomy placement for gastrointestinal cancer: Roles, goals, and complications

Percutaneous endoscopic gastrostomy tube placement is an invaluable tool in clinical practice that has an important role in the palliative care of patients with gastrointestinal cancer. While there is no extensive data regarding the use of this procedure in patients with gastrointestinal malignancy, inferences can be made from the available information derived from studies of similar or mixed populations. Percutaneous endoscopic gastrostomy tubes can be used to provide enteral nutrition for terminal malignancies of the upper gastrointestinal tract as well as for decompression of malignant obstructions. The rates of successful placement for cancer patients with either of these indications are high, similar to those in mixed populations. There is no conclusive evidence that the procedure will help patients reach nutritional goals for those needing alimental supplementation. However, it is effective at relieving symptoms caused by malignant obstruction. A high American Society of Anesthesiologist physical status score and an advanced tumor stage have been shown to be independent predictors of poor outcomes following placement in cancer patients. This suggests the potential for similar outcomes in the palliative care of patients with advanced stage gastrointestinal cancer who may be in relatively poor physiologic condition. However, this potential should not preclude its use in patients with terminal gastrointestinal cancer considering the high rate of successful tube placement, the possible benefits and the ultimate goal of comfort in palliative care.

Over-the-scope-clip closure of long lasting gastrocutaneous fistula after percutaneous endoscopic gastrostomy tube removal in immunocompromised patients:A single center case series

Over-the-scope-clips (OTSC®) have been shown to be an effective and safe endoscopic treatment option for the closure of gastrointestinal perforations, leakages and fistulae. Indications for endoscopic OTSC® treatment have grown in number and also include gastro cutaneous fistula (GCF) after percutaneous endoscopic gastrostomy (PEG) tube removal. Non-healing GCF is a rare complication after removal of PEG tubes and may especially develop in immunosuppressed patients with multiple comorbidities. There is growing evidence in the literature that OTSC® closure of GCF after PEG tube removal is emerging as an effective, simple and safe endoscopic treatment option. However current evidence is limited to the geriatric population and short standing GCF, while information on closure of long standing GCF after PEG tube removal in a younger population with significant comorbidities is lacking. In this retrospective single-center case-series we report on five patients undergoing OTSC® closure of chronic GCF after PEG tube removal. Four out of five patients were afflicted with long lasting, symptomatic fistulae. All five patients suffered from chronic disease associated with a catabolic metabolism (cystic fibrosis, chemotherapy for neoplasia, liver cirrhosis). The mean patient age was 43 years. The mean dwell time of PEG tubes in all five patients was 808 d. PEG tube dwell time was shortest in patient 5 (21 d). The mean duration from PEG tube removal to fistula closure in patients 1-4 was 360 d (range 144-850 d). The intervention was well tolerated by all patients and no adverse events occured. Successful immediate and long-term fistula closure was accomplished in all five patients. This single center case series is the first to show successful endoscopic OTSC® closure of long lasting GCF in five consecutive middle-aged patients with significant comorbidities. Endoscopic closure of chronic persistent GCF after PEG tube removal using an OTSC® was achieved in all patients with no immediate or long-term complications. OTSC® is a promising endoscopic treatment option for this condition with a potentially high immediate and long term success rate in patients with multiple comorbidities.

Is percutaneous endoscopic gastrostomy tube placement safe in patients with ventriculoperitoneal shunts?

AIM:To investigate whether percutaneous endoscopic gastrostomy (PEG) tube placement is safe in patients with ventriculoperitoneal (VP) shunts.METHODS: This was a retrospective study of all patients undergoing PEG insertion at our institution between June 1999 and June 2006. Post-PEG complications were compared between two groups according to the presence or absence of VP shunts. VP shunt infection rates, the interval between PEG placement and VP shunt catheter insertion, and long-term follow-up were also investigated.RESULTS: Fifty-five patients qualified for the study. Seven patients (12.7%) had pre-existing VP shunts. All patients received prophylactic antibiotics. The complication rate did not differ between VP shunt patients undergoing PEG (PEG/VP group) and non-VP shunt patients undergoing PEG (control group) [1 (14.3%) vs 6 (12.5%), P=1.000]. All patients in the PEG/VP group had undergone VP shunt insertion prior to PEG placement. The mean interval between VP shunt insertion and PEG placement was 308.7 d (range, 65-831 d). The mean follow-up duration in the PEG/VP group was 6.4 mo (range, 1-15 mo). There were no VP shunt infections, although one patient in the PEG/VP group developed a minor peristomal infection during follow-up.CONCLUSION: Complications following PEG placement in patients with VP shunts were infrequent in this study.

Usefulness of percutaneous endoscopic gastrostomy for supportive therapy of advanced aerodigestive cancer

Aerodigestive cancer, like esophageal cancer or head and neck cancer, is well known to have a poor prognosis. It is often diagnosed in the late stages, with dysphagia being the major symptom. Insufficient nutrition and lack of stimulation of the intestinal mucosa may worsen immune compromise due to toxic side effects. A poor nutritional status is a significant prognostic factor for increased mortality. Therefore, it is most important to optimize enteral nutrition in patients with aerodigestive cancer before and during treatment, as well as during palliative treatment. Percutaneous endoscopic gastrostomy(PEG) may be useful for nutritional support. However, PEG tube placement is limited by digestive tract stenosis and is an invasive endoscopic procedure with a risk of complications. There are three PEG techniques. The pull/push and introducer methods have been established as standard techniques for PEG tube placement. The modified introducer method, namely the direct method, allows for direct placement of a larger button-bumper-type catheter device. PEG tube placement using the introducer method or the direct method may be a much safer alternative than the pull/push method. PEG may be recommended in patients with aerodigestive cancer because of the improved complication rate.

Bowel intussusception caused by a percutaneously placed endoscopic gastrojejunostomy catheter: A case report

BACKGROUND In adults,bowel intussusception is a rare diagnosis and is mostly due to an organic bowel disorder.In rare cases,this is a complication of a percutaneously placed endoscopic gastro(jejunostomy)catheter.CASE SUMMARY We describe a case of a 73-year-old patient with a history of myocardial infarction,chronic idiopathic constipation and Parkinson’s disease.For the admission of his Parkinson’s medication,a percutaneous endoscopic gastrostomy with jejunal extension(PEG-J)was placed.The patient presented three times at the emergency department of the hospital with intermittent abdominal pain with nausea and vomiting.There were no distinctive abnormalities from the physical and laboratory examinations.An abdominal computed tomography scan showed a small bowel intussusception.By push endoscopy,a jejunal bezoar at the tip of the PEG-J catheter was found to be the cause of small bowel intussusception.The intussusception was resolved after removing the bezoar during push enteroscopy.CONCLUSION Endoscopic treatment of bowel intussusception caused by PEG-J catheter bezoar.
