Patient characteristics and procedural and safety outcomes of percutaneous transesophageal gastro-tubing: A nationwide database study in Japan

BACKGROUND

Percutaneous transesophageal gastro-tubing (PTEG) is an alternative interventional procedure in cases where gastrostomy is not feasible. However, the safety and complication rates of PTEG have not yet been evaluated. We aimed to describe the characteristics of patients who underwent PTEG and investigate complications using a nationwide Japanese inpatient database.

METHODS

In this retrospective cohort study, we used the Diagnosis Procedure Combination database in Japan to identify patients who underwent PTEG from April 2012 to March 2020. The outcomes were the occurrence of complications, invasive treatment within 7 days after PTEG, and tube replacement within 14 days after PTEG. We statistically compared patient background, complication rates, and outcomes using PTEG indications.

RESULTS

A total of 3,684 patients underwent PTEG, which was performed in 1,455 patients for decompression and 2,193 patients for feeding. The patients' mean age was 73.1 years, and 62.1% were men. More patients in the decompression group had cancer than those in the feeding group. The overall number of complications was 47 cases (1.3%). The most common treatment administered after PTEG was red blood cell transfusion (3.9%), followed by early tube replacement (3.3%). As invasive treatments for PTEG complications, percutaneous drainage and transcatheter arterial embolization were required in 4 and 1 cases, respectively, and no cases required surgery.

CONCLUSION

We performed a descriptive study on PTEG using a nationwide database in Japan. This study also showed a low complication rate after PTEG in the real world. Our findings provide practical information on the safety of PTEG in Japan.

Mid-to-long-term outcomes with image-guided placement of de novo low-profile gastrojejunostomy tubes in pediatric patients

OBJECTIVE

De novo low-profile gastrojejunostomy (GJ) tubes are advantageous in children that require prolonged supplemental nutrition. However, few institutions place these devices at the time of initial feeding tube placement. We aim to build upon our previously published initial experience with this procedure to study mid-to-long-term outcomes of pediatric patients who have had de novo, image-guided, percutaneous low-profile GJ tube placement.

METHODS

All de novo, image-guided, percutaneous, low-profile GJ tube placements at a single children's hospital were retrospectively reviewed between May 2014 and March 2021. Technical parameters, including fluoroscopy time, tube size, technical success, and complications were recorded. Clinical data, including age, indication, weight gain and transition to gastric/oral feeds were analyzed.

RESULTS

64 de novo low-profile GJ tubes were successfully placed in 65 patients (mean age: 4.6 years, median: 1, range: 0.2-19; mean pre-procedural weight: 16.8 kg, median: 8.2, range: 4.4-66.7). Average clinical follow-up 23.4 months (range: 0.1-75, median 10.4). Average weight gain was 6.1 kg. Average increase in weight percentile was 7.3%. 19 (19/64; 29.7%) patients had conversion from GJ to G tube. 11 (11/64; 17.2%) patients had their enteric tube removed completely. There were 7 minor complications (7/65; 10.7%), most common being excessive skin irritation (6/7) and 9 major complications (9/65; 13.8%), most common being tube dislodgment within the first 30 days (6/9).

CONCLUSIONS

These results further support that de novo, image-guided, percutaneous, low-profile GJ tube placement is technically feasible and efficacious in children requiring post-pyloric nutritional supplementation with a favorable safety profile.

CT Fluoroscopy-Guided Percutaneous Gastrostomy in the Palliative Management of Advanced and Relapsed Ovarian Cancer: The Charité Experiences and a Review of the Literature

Peritoneal carcinomatosis-associated malignant bowel obstruction is a common feature that merits more attention in advanced and recurrent ovarian cancer. Decompressive gastrostomy is one of the most preferred methods to palliate distressing symptoms and maintain patients' quality of life. We retrospectively identified 31 patients with ovarian cancer-associated MBO, who underwent decompressive CT fluoroscopy-guided percutaneous gastrostomy (CT-PG) between September 2015 and April 2023 at our institution. A systematic literature review was conducted for CT-guided gastrostomy in ovarian cancer. Prior to CT-PG, 27 (87%) patients underwent unsuccessful attempts at endoscopic gastrostomy or surgery due to bowel obstruction; a total of 55% had received ≥3 lines of chemotherapy. CT-PG could be successfully inserted in 25 of 31 (81%) patients without grade 4-5 complications. CT-PG insertion was feasible in 76% of patients with previous unsuccessful attempts of endoscopic gastrostomy. A total of 80% of patients with a successful insertion had considerable symptom relief and could tolerate fluid intake. Mean survival after the procedure was 44.4 days. Chemotherapy could be administered in 7 of 25 (28%) patients following the CT-PG insertion. CT-guided percutaneous gastrostomy is a safe procedure that effectively manages intractable symptoms of bowel obstruction in ovarian cancer. This minimally invasive technique should be emphasised as a routine instrument within the palliative management of MBO.

Who Places Feeding Tubes and in What Scenario?

PURPOSE OF REVIEW

Enteral feeding is commonly used to provide patients with nutrition. Access via feeding tubes can be attained by multiple medical specialties through a variety of methods.

RECENT FINDINGS

There are limited data available on direct comparisons amongst gastroenterologist, interventional radiologists and surgeons, although there appears to be similar rates of complications. Fluroscopically and surgically placed feeding tubes may have a higher technical success rate than endoscopically placed tubes. The preferred specialty for feeding tube placement varies per institution, often due to logistical matters over technique or concern for complications. Ideally, a multidisciplinary team should exist to determine which approach is best in a patient-specific manner.

A randomized trial comparing percutaneous endoscopic gastrostomy (PEG) and radiologically inserted percutaneous gastrostomy (RIG)

BACKGROUND AND OBJECTIVE

At present, percutaneous endoscopic gastrostomy (PEG) is the procedure of choice in establishing a permanent feeding tube in patients with chronic severe dysphagia. This is the first prospective randomized study in adults comparing PEG with radiologically inserted gastrostomy (RIG).

METHODS

Randomization of 106 patients, eligible for both techniques, to PEG (pull method) or RIG. The groups were comparable in terms of age, body mass index, and underlying diseases. Adverse events were reported 10 and 30 days after the operative procedure, and mortality was up until 6 months. The validated European Quality of life 5 Dimensions 3 level version (EQ-5D) questionnaire was used for health status measurements.

RESULTS

The procedures were successfully completed in all patients. The median operative time was 10 min for PEG and 20 min for RIG (p < 0.001). The overall rate of adverse events was lower for PEG (22%) than for RIG (51%, p = 0.002), mostly due to less local self-limiting stoma reactions and tube problems. The 30-day mortality was lower after PEG (2% versus 14%, p = 0.020). Patient-scored health status remained low for the entire cohort, with an EQ-5D utility index of 0.164. Self-rated health was low but improved in the RIG group (52.5 from 41.1, out of 100).

CONCLUSION

PEG can be recommended as the primary procedure in patients in need of a feeding gastrostomy, mainly due to a lower frequency of tube complications. However, as the two techniques complement each other, RIG is also a valid alternative method.

Primary placement of low-profile or 'button' versus traditional balloon-retention radiologically inserted gastrostomy catheters in adults: a retrospective review

OBJECTIVE

De novo percutaneous placement of radiologically inserted low-profile or 'button-type' gastrostomy catheters (LPG) is infrequently reported in adults. This study compares the safety and clinical outcomes of primary percutaneous placement of LPG catheters and traditional balloon-retention gastrostomy catheters (TG) using image guidance at a single institution.

DESIGN

This was a retrospective, single-institution review comparing initial LPG and TG radiologically inserted catheter placements in a 36-month time period. The age, gender, indication, catheter type and method of anaesthesia of 139 consecutive initial gastrostomy placement procedures were recorded. Total catheter days without intervention, major and minor complications, reasons for reintervention, and procedure fluoroscopy times were compared.

RESULTS

During the 36-month study period, 61 LPG and 78 TG catheters were placed. Mean total catheter days prior to intervention was 137 days in the LPG group and 128 days in the TG group (p=0.70). Minor complications including cellulitis, pericatheter leakage and early catheter occlusion occurred in 4.9% (3/61) in the LPG group and 9% (7/78) in the TG group (p=0.5). Major complications including early catheter dislodgement and bleeding requiring transfusion (in one patient) occurred in 4.9% (3/61) in the LPG group and 7.7% (6/78) in the TG group (p=0.4). Procedure fluoroscopy time was lower in the LPG group (2.56 min) compared with the TG group (4.21 min) (p<0.005).

CONCLUSION

Primary placement of low-profile or 'button-type' gastrostomy catheters is technically feasible with a low complication rate similar to that of traditional radiologically inserted gastrostomy catheters.

Weighted Tip Extensions Result in Fewer Gastrojejunostomy Tube Migrations and Increase Tube Lifespan

PURPOSE

To investigate the safety and efficacy of attaching a weighted extension to the distal aspect of prefabricated gastrojejunostomy (GJ) tubes, and to determine whether this alteration reduces the occurrences of tip reflux into the esophagus or stomach.

MATERIALS AND METHODS

This retrospective 1-way crossover study included 64 GJ tubes in 15 patients placed by multiple operators in the interventional radiology department at a single institution from July 1, 2019, to December 1, 2021. Patients were selected for a weighted tip extension if they required a GJ tube exchange because of the distal tip refluxing into the stomach or esophagus and were aged ≥18 years. These modified GJ tubes were prepared by cutting the distal end of a nasojejunal tube to a length of 10-15 cm and suturing to the distal aspect of the GJ tube.

RESULTS

Of the 64 tubes studied, 37 had a weighted tip extension. The unmodified GJ tubes had a mean lifespan of 34.3 days, which was significantly shorter than the weighted tips (92.8 days; t test P = .001). There was 1 limited adverse event of abdominal pain and spasms that resolved after exchange with a shorter weighted extension.

CONCLUSIONS

This study suggests that for patients who require a GJ tube replacement because of the tip refluxing proximally into the stomach or esophagus, the addition of a 10-15-cm weighted extension to the distal end of the GJ tube is safe and significantly improves the lifespan of the enteric tube.

O que o radiologista deve saber sobre o papel da gastrostomia percutânea: ensaio iconográfico

Resumo As técnicas de gastrostomia guiadas por imagem, por via transoral e transabdominal podem ser realizadas quando há falha na técnica endoscópica ou em cenários clínicos em que a endoscopia não pode ser realizada. Este ensaio iconográfico pretende mostrar as técnicas de gastrostomia percutânea, suas indicações, aspectos técnicos, cuidados pós-procedimento e complicações.

What the radiologist should know about the role of percutaneous gastrostomy: a pictorial essay

Abstract The image-guided gastrostomy techniques, as transoral and transabdominal, can be performed when there is a failure of the endoscopic procedure or in some specific clinical scenarios. This pictorial essay intends to show the percutaneous gastrostomy techniques, indications, technical approaches, post-procedure care, and complications.

Managing complications of percutaneous tracheostomy and gastrostomy

Percutaneous tracheostomy and gastrostomy are some of the most commonly performed procedures at bedside in the intensive care unit. While they are generally considered safe, they can be associated with numerous short and long-term complications, many of which can occur long after their placement and cause significant morbidity. Performers of these procedures should possess a comprehensive understanding of procedural indications and contraindications, and know how to recognize and manage complications that may arise. In this review, we highlight complications of percutaneous tracheostomy and describe strategies for their prevention and management, with a special focus on post-tracheostomy tracheal stenosis. Other complications reviewed include bleeding, pneumothorax and subcutaneous emphysema, posterior wall injury, tube displacement, tracheomalacia, tracheoinominate artery fistula, tracheo-esophageal fistula, and stomal cellulitis. Gastrostomy complications and their management are also discussed including bleeding, internal organ injury, necrotizing fasciitis, aspiration pneumonia, buried bumper syndrome, tumor seeding, wound infection, tube displacement, peristomal leakage, and gastric outlet obstruction. In light of the potentially serious outcomes associated with complications of percutaneous tracheostomy and gastrostomy, the emphasis should be placed on risk-reduction strategies to minimize morbidity and mortality. We therefore present detailed pragmatic and comprehensive checklists to serve as a reference for clinicians involved in performing these procedures.

Laparoscopic-Percutaneous Combined Gastrostomy: Initial Experience and Description of a Technique

Background: Gastrostomy is a widely used procedure that aims to obtain access to the stomach. Its purpose may be feeding or gastric decompression. Currently, the most common techniques are endoscopic and radiologic. Sometimes, these accesses are not available due to technical or patient-specific factors. In these cases, laparoscopic and percutaneous approaches combined could be an option. The aim of this study was to describe a laparoscopic-percutaneous combined gastrostomy procedure, feasibility, and complications. Materials and Methods: Retrospective descriptive observational study. All patients underwent laparoscopic-percutaneous combined gastrostomy required for feeding or decompressive gastrostomy. We analyzed variables: demographics, surgical indication, operation time, hospitalization stay, success, and morbidity/mortality associated to the procedure. Results: A total of n = 17 patients were recruited (58.8% women and 41.2% men), with mean age of 53. Regarding the indications of laparoscopic-percutaneous combined gastrostomy, 47% were due to upper gastrointestinal/head and neck tumor, 29.4% stomach location in a retrocostal position, 17.7% colonic interposition, and 5.9% acute gastric dilation of remnant after Roux-en-Y gastric bypass. The mean time of the procedure was 25 minutes, and mean hospitalization stay was 1.2 days. The success of the procedure was 100%. No complications and mortality associated with the procedure were reported. Conclusion: Laparoscopic-percutaneous combined gastrostomy is fast, feasible, safe, and cost effective. It is an option in patients where it is not possible to perform standard minimally invasive approaches.

Comparing the Safety and Cost of Image-Guided Percutaneous Gastrostomy Tube Placement in the Outpatient Versus Overnight Observation Setting in a Single-Center Retrospective Study

RATIONALE AND OBJECTIVES

Historically, patients undergoing image-guided percutaneous gastrostomy tube placement have been admitted overnight with feeds commencing 12-24 hours postprocedure. With new expedited feeding protocols starting 3-4 hours postprocedure, same-day discharge is now possible. The purpose of this study was to evaluate the safety and cost of image-guided percutaneous gastrostomy tube placement as an outpatient procedure.

MATERIALS AND METHODS

In this retrospective study, 131 patients (age 63.9 ± 11.6; 34% female) underwent gastrostomy tube placement as an outpatient procedure with expedited feeding protocol versus 40 patients (age 61.3 ± 12.6; 38% female) who were hospitalized overnight with feeds starting at 12-24 hours, primarily based on operator preference. The two groups were compared regarding complications within 90 days of procedure. Using a subgroup of 33 consecutive patients, procedural costs (total combined insurer and patient payments for professional and hospital services) for outpatients vs. hospitalized patients were compared.

RESULTS

Complication rates were similar (p = 0.64) for gastrostomy tubes placed on outpatients (0.17 complications/procedure: 4 bleeding, 2 aspiration pneumonia, 1 abdominal abscess, 4 significant pain, 6 cellulitis, 1 surgical consult, 4 malpositioned/fractured tubes) and hospitalized patients (0.20 complications/procedure: 1 aspiration pneumonia, 1 significant pain, 3 cellulitis, 1 surgical consult, 2 fractured tubes). Total combined insurer and patient payments were similar ($2193/outpatient vs $2701/hospitalized patient; p= 0.52).

CONCLUSION

Outpatient image-guided percutaneous gastrostomy tube placement with an expedited feeding protocol is a safe and cost-comparable alternative to historic overnight hospitalization. Further prospective investigation with a larger sample is warranted.

Single-session versus two-session placement of chest port and gastrostomy tube in patients with head and neck cancer: Is there any difference in the device-related early infection rates?

BACKGROUND

It is unknown whether placement of a chest port (port) and a gastrostomy tube (G-tube) in a single session increases the risk of the early device infections in patients with head and neck cancer (HNC) undergoing chemoradiation.

PURPOSE

To compare the incidence of early (≤30 days) port and G-tube infections placed in a single session compared to two separate sessions in patients with HNC.

MATERIAL AND METHODS

Between January 2012 and December 2019, 169 patients with HNC undergoing chemoradiation had a port and a G-tube placed in a single session (single-session group), while 25 had both devices placed in two separate sessions (two-session group) within 30 days of each other. The incidence of early device infections was compared between groups. Logistic regression analysis was conducted to determine if the number of sessions was a variable affecting device infections.

RESULTS

A total of 6 (3%) early port infections and 13 (6.7%) early G-tube infections were identified. The two groups did not significantly differ in the incidence of early port infections (3.0%, 5/169 and 4.0%, 1/25, p = 0.59) nor early G-tube infections (7.1%, 12/169 and 4.0%, 1/25, p = 1.0). The number of sessions for device placement was not a variable affecting overall device infections in logistic regression analyses (odds ratio: 1.24, 95% confidence interval: 0.20-7.82, p = 0.82) after controlling for potential confounding variables.

CONCLUSIONS

The risk of early device infections in single-session placement appeared to be the same as two-session placement in patients with HNC undergoing chemoradiation.

Percutaneous Ultrasound Guided Gastrostomy Tube Placement: A Prospective Cohort Trial

BACKGROUND

To compare the safety and efficacy of percutaneous ultrasound guided gastrostomy (PUG) tube placement with traditional fluoroscopic guided percutaneous gastrostomy tube placement (PRG).

METHODS

A prospective, observational, non-randomized cohort trial was performed comparing 25 consecutive patients who underwent PUG placement between April 2020 and August 2020 with 25 consecutive patients who underwent PRG placement between February 2020 and March 2020. Procedure time, sedation, analgesia requirements, and complications were compared between the two groups in non-inferiority analysis.

RESULTS

Technical success rates were 96% in both groups (24/25) of procedures. Ninety-two percent of patients in the PUG cohort were admitted to the ICU at the time of G-tube request. Aside from significantly more COVID-19 patients in the PUG group (P < .001), there was no other statistically significant difference in patient demographics. Intra-procedure pain medication requirements were the same for both groups, 50 micrograms of IV fentanyl (P = 1.0). Intra-procedure sedation with IV midazolam was insignificantly higher in the PUG group 1.12 mg vs 0.8 mg (P = .355). Procedure time trended toward statistical significance (P = .076), with PRG being shorter than PUG (30.5 ± 14.1 minutes vs 39.7 ± 17.9 minutes). There were 2 non-device related major complications in the PUG group and 1 major and 1 minor complication in the PRG group.

CONCLUSION

PUG is similar in terms of complications to PRG gastrostomy tube placement and a safe method for gastrostomy tube placement in the critically ill with the added benefits of bedside placement, elimination of radiation exposure, and expanded and improved access to care.

Adherence to the RIGHT statement in Society of Interventional Radiology guidelines

Context

The Reporting Items for Practice Guidelines in Health Care (RIGHT) Statement was developed by a multidisciplinary team of experts to improve reporting quality and transparency in clinical practice guideline development.

Objective

To assess the quality of reporting in clinical practice guidelines put forth by the Society of Interventional Radiology (SIR) and their adherence to the RIGHT statement checklist.

Methods

In March 2018, using the 22 criteria listed in the RIGHT statement, two researchers independently documented adherence to each item for all eligible guidelines listed by the SIR by reading through each guideline and using the RIGHT statement elaboration and explanation document as a guide to determine if each item was appropriately addressed as listed in the checklist. To qualify for inclusion in this study, each guideline must have met the strict definition for a clinical practice guideline as set forth by the National Institute of Health and the Institute of Medicine, meaning they were informed by a systematic review of evidence and intended to direct patient care and physician decisions. Guidelines were excluded if they were identified as consensus statements, position statements, reporting standards, and training standards or guidelines. After exclusion criteria were applied, the two researchers scored each of the remaining clinical practice guidelines (CPGs) using a prespecified abstraction Google form that reflected the RIGHT statement checklist (22 criteria; 35 items inclusive of subset questions). Each item on the abstraction form consisted of a “yes/no” option; each item on the RIGHT checklist was recorded as “yes” if it was included in the guideline and “no” if it was not. Each checklist item was weighed equally. Partial adherence to checklist items was recorded as “no.” Data were extracted into Microsoft Excel (Microsoft Corporation) for statistical analysis.

Results

The initial search results yielded 129 CPGs in the following areas: 13 of the guidelines were in the field of interventional oncology; 16 in neurovascular disorders; five in nonvascular interventions; four in pediatrics; 25 in peripheral, arterial, and aortic disease; one in cardiac; one in portal and mesenteric vascular disease; 37 in practice development and safety; three in spine and musculoskeletal disorders; 14 in venous disease; five in renal failure/hemodialysis; and five in women’s health. Of the 46 guidelines deemed eligible for evaluation by the RIGHT checklist, 12 of the checklist items showed less than 25% adherence and 13 showed more than 75% adherence. Of 35 individual RIGHT statement checklist items, adherence was found for a mean (SD) of 22.9 items (16.3). The median number of items with adherence was 21 (interquartile range, 7.5–38).

Conclusion

The quality of reporting in interventional radiology guidelines is lacking in several key areas, including whether patient preferences were considered, whether costs and resources were considered, the strength of the recommendations, and the certainty of the body of evidence. Poor adherence to the RIGHT statement checklist in these guidelines reveals many areas for improvement in guideline reporting.

Retrospective Analysis of the Safety and Outcomes of Percutaneous Radiologic Gastrostomy in Obese vs Nonobese Patients

BACKGROUND

The purpose of this study is to compare the safety and outcomes of percutaneous radiologic gastrostomy (PRG) in obese vs nonobese patients.

METHODS

This is an institutional review board-approved retrospective study of 109 patients (male:female, 68:41; mean age, 64.7 years; range, 21-94 years) who underwent PRG with or without gastropexy at a single academic medical center between 2015 and 2018. Body mass index (BMI) of ≥30 kg/m² was defined as obese. Patient demographics, indications, technical success, intraoperative variables, and major/minor complications were analyzed. Major and minor complications occurring within 30 days of the procedure were recorded and categorized based on the Society of Interventional Radiology Quality Improvement guidelines.

RESULTS

Of 109 patients included in the study, 22.9% (n = 25) of patients were obese (average BMI, 34.6 kg/m² ; range, 30-50). Overall technical success in the obese and nonobese groups was 100% each. In the obese vs nonobese group, major and minor complications were not significantly different. There were also no significant differences in procedure time, fluoroscopy time, or contrast volume. However, mean peak skin dose was significantly increased in the obese group vs nonobese group (190.3 ± 224.2 vs 59.1 ± 71.1 mGy; P < .0001).

CONCLUSION

PRG is a safe procedure in obese patients with similar technical success, major and minor complication rates, procedure time, fluoroscopy time, and contrast volume. However, PRG is associated with increased radiation dose with obese patients; therefore, optimal methods of radiation protection should be utilized.

Rectal Bleeding after Insertion of a Percutaneous Endoscopic Gastrostomy Tube

Iatrogenic injury to an internal organ such as the stomach, colon, small bowel, or liver after percutaneous endoscopic gastrostomy (PEG) tube insertion is a rare complication. We present a case of rectal bleeding due to colon injury during PEG tube placement. This required urgent exploratory laparoscopic surgery with segmental resection of the transverse colon and replacement of the PEG tube. Postoperatively, the patient significantly improved with time and tolerated PEG tube feeding.

Percutaneous gastrojejunostomy tubes: Identification of predictors of retrograde jejunal limb migration into the stomach

PURPOSE

To identify whether technically modifiable factors during gastrojejunostomy (GJ) tube insertion are predictive of retrograde jejunal limb migration into the stomach.

MATERIALS AND METHODS

Retrospective review of our procedural database over a 5-year period revealed 988 successful primary GJ tube insertions. Medical records and imaging were reviewed for cases of retrograde jejunal limb migration. Primary analysis was performed on 74 patients with retrograde tip migration within 3 months after placement (37 males, mean age = 57). Comparison was performed on 67 control patients (34 males, mean age = 51) who had radiologically confirmed GJ tube stability for at least 6 months. Procedural fluoroscopic images were analyzed for multiple GJ tube configuration parameters. The stomach was designated into antrum, body, and fundus. Predictors of retrograde tip migration were analyzed with univariate and multivariate logistic regression analysis.

RESULTS

A total of 110 patients (11.1%) had retrograde jejunal limb migration, with 74 (7.5%) occurring within 3 months of placement. On multivariate analysis, the factors associated with a significantly lower risk of tip malposition included gastric puncture site in the antrum (OR: 0.27, 95% CI: 0.13-0.56, p < 0.001) and GJ tract angle less than 30 degrees away from the pylorus (OR: 0.35, 95% CI: 0.16-0.76, p = 0.008). No patient in either cohort had a major complication within 30 days of procedure.

CONCLUSION

To minimize the risk of retrograde tip migration, GJ tubes should be inserted into the gastric antrum with an entry tract oriented as directly towards the pylorus as possible.

Metoclopramide Reduces Fluoroscopy and Procedure Time during Gastrojejunostomy Tube Placement: A Placebo-Controlled Trial

PURPOSE

To determine whether a single 10-mg intravenous dose of the promotility agent metoclopramide reduces the fluoroscopy time, radiation dose, and procedure time required for gastrojejunostomy (GJ) tube placement.

METHODS

This prospective, randomized, double-blind, placebo-controlled trial enrolled consecutive patients who underwent primary GJ tube placement at a single institution from April 10, 2018, to October 3, 2019. Exclusion criteria included age less than 18 years, inability to obtain consent, metoclopramide allergy or contraindication, and altered pyloric anatomy. Average fluoroscopy times, radiation doses, and procedure times were compared using t-tests. The full study protocol can be found at www.clinicaltrials.gov (NCT03331965).

RESULTS

Of 110 participants randomized 1:1, 45 received metoclopramide and 51 received placebo and underwent GJ tube placement (38 females and 58 males; mean age, 55 ± 18 years). Demographics of the metoclopramide and placebo groups were similar. The fluoroscopy time required to advance a guide wire through the pylorus averaged 1.6 minutes (range, 0.3-10.1 minutes) in the metoclopramide group versus 4.1 minutes (range, 0.2-27.3 minutes) in the placebo group (P = .002). Total procedure fluoroscopy time averaged 5.8 minutes (range, 1.5-16.2 minutes) for the metoclopramide group versus 8.8 minutes (range, 2.8-29.7 minutes) for the placebo group (P = .002). Air kerma averaged 91 mGy (range, 13-354 mGy) for the metoclopramide group versus 130 mGy (range, 24-525 mGy) for the placebo group (P = .04). Total procedure time averaged 16.4 minutes (range, 8-51 minutes) for the metoclopramide group versus 19.9 minutes (range, 6-53 minutes) for the placebo group (P = .04). There were no drug-related adverse events and no significant differences in procedure-related complications.

CONCLUSIONS

A single dose of metoclopramide reduced fluoroscopy time by 34%, radiation dose by 30%, and procedure time by 17% during GJ tube placement.

Jejunostomy Tube Insertion for Enteral Nutrition: Comparison of Outcomes after Laparoscopic versus Radiologic Insertion

PURPOSE

To retrospectively compare technical success and major complication rates of laparoscopically versus radiologically inserted jejunostomy tubes.

MATERIALS AND METHODS

In this single-institution retrospective study, 115 patients (60 men; mean age, 59.7 y) underwent attempted laparoscopic jejunostomy tube insertion as a standalone procedure during a 10-year period and 106 patients (64 men; mean age, 61.0 y) underwent attempted direct percutaneous radiologic jejunostomy tube insertion during an overlapping 6-year period. Clinical outcomes were retrospectively reviewed with primary focus on predictors of procedure-related major complications within 30 days.

RESULTS

Patients undergoing laparoscopic jejunostomy tube insertion were less likely to have previous major abdominal surgery (P < .001) or to be critically ill (P < .001) and had a higher body mass index (P = .001) than patients undergoing radiologic insertion. Technical success rates were 95% (110 of 115) for laparoscopic and 97% (103 of 106) for radiologic jejunostomy tube insertion (P = .72). Major procedural complications occurred in 7 patients (6%) in the laparoscopic group and in 5 (5%) in the radiologic group (P = 1.0). For laparoscopic jejunostomy tubes, only previous major abdominal surgery was significantly associated with a higher major procedure complication rate (14% [5 of 37] vs 3% [2 of 78] in those without; P = .039). In the radiologic jejunostomy group, only obesity was significantly associated with a higher major complication rate: 20% (2 of 10) vs 3% (3 of 96) in nonobese patients (P = .038).

CONCLUSIONS

Laparoscopic and radiologic jejunostomy tube insertion both showed high success and low complication rates. Previous major abdominal surgery and obesity may be pertinent discriminators for patient selection.

A Literature Review of Percutaneous Endoscopic Gastrostomy: Dealing With Complications

Sufficient energy and essential nutrients are vital for normal growth and development in childhood. Ideally, nutrition should be provided orally. However, if the gastrointestinal system is functional, enteral tube feeding can be used when nutritional requirements cannot be provided orally, thus providing nutritional benefits and enabling positive disease management in pediatric patients. Postoperative care in children allows monitoring of the position and functionality of the tube; performing nutrition intolerance, growth, hydration, and nutritional assessments; and performing metabolic and complication follow-ups. Tube feeding in pediatric patients is beneficial and has positive effects in controlling and managing diseases and providing appropriate nutrition in children. However, in postoperative patients, it is important to prevent potential complications, which can be classified into 5 groups: mechanical, gastrointestinal, metabolic, infectious, and pulmonary complications. Important points for managing complications include having enteral nutrition practices based on evidence-based guidelines, sharing outcomes with nurses working in clinical settings, creating enteral feeding guides in clinical settings, providing patients/patients' family with training in line with these guides, and maintaining follow-ups at home. This literature review discusses complications and practices regarding the management of complications after percutaneous endoscopic gastrostomy.

Utility of pre-procedural CT and abdominal radiography before percutaneous radiologic gastrostomy placement

PURPOSE

To evaluate the utility of pre-procedural CT and abdominal radiography before percutaneous radiologic gastrostomy tube placement.

METHODS

A retrospective review of gastrostomy tube placements was conducted at a tertiary care radiology department. During the studied period, all percutaneous radiologic G-tube placements (PRG) at the institution required a pre-procedural abdominal CT. Whether the CT was interpreted to have an adequate window for PRG was recorded. The same patients with pre-procedural abdominal radiographs were also identified and retrospectively reviewed for the presence of satisfactory anatomy for PRG. Outcomes of tube placements were reviewed.

RESULTS

126 PRG requests were identified, all with abdominal CTs. 110 also had an abdominal radiograph. An adequate window for PRG was present in 83% of patients by CT and 73% by radiography. Of patients in whom it was attempted, 94% underwent successful PRG with a 7.4% minor complication rate. Of those refused for PRG based on CT, 9% had successful percutaneous endoscopic G-tube placement, resulting in a sensitivity of 98%. 97% of patients with satisfactory anatomy by radiograph underwent successful PRG. Of those with no window, 66% had a window by CT, and 94% in whom it was attempted had successful PRG placement. This resulted in a sensitivity of 77% for radiography. Concordance between CT and radiography was 73%.

CONCLUSIONS

Pre-procedural CT interpretation is highly predictive of successful and uncomplicated PRG. Abdominal radiography also predicts successful PRG, but with a lower accuracy, limiting its utility as a pre-procedural exam.

Percutaneous endoscopic versus radiologic gastrostomy for enteral feeding: a retrospective analysis on outcomes and complications

Background and study aims  Percutaneous endoscopic gastrostomy (PEG) and percutaneous radiologic gastrostomy (PRG) are techniques used for long-term enteral feeding. Our primary aim was to analyze procedure-related and 30-day mortality and complications between PEG and PRG in relation to indications. Patients and methods  A single-center retrospective analysis was performed thath included all adult patients receiving initial PEG (January 2008 until April 2016) and PRG (January 2010 until April 2016). Outcomes were mortality (procedure-related, 30-day), complications (early (≤ 30 days) and late) and success rates. Results  A total of 760 procedures (469 PRG and 291 PEG) were analyzed. Most common indications were head and neck cancer (HNC), cerebrovascular accident (CVA) and amyotrophic lateral sclerosis (ALS). Success rates for placement were 91.2 % for PEG and 97.1 % for PRG ( P  = 0.001). Procedure-related mortality was 1.7 % in PEG and 0.4 % in PRG ( P  = 0.113). The 30-day mortality was 10.7 % in PEG and 5.1 % in PRG ( P  = 0.481 after multivariate logistic regression) CVA was associated with higher 30-day mortality, whereas ALS, higher body weight, and prophylactic placements in HNC were associated with lower rates. Tube-related complications were less frequent in PEG, both early (2.7 % vs. 26.4 %, P  ≤ 0.001) and late (8.6 % vs. 31.5 %, P  ≤ 0.001). The percentage of major complications and infections did not differ. Conclusions  With respect to procedure-related and 30-day mortality, PEG and PRG compare equally. PRG had a higher procedural success rate. Tube-related complications and pain are less frequent after PEG compared to PRG. The choice for either PEG or PRG therefore should primarily be based on local facilities and expertise.

The occlusion balloon reduction technique for de novo placement and salvage of malpositioned enteric tubes

PURPOSE

Nasoenteric, gastrojejunostomy, and jejunostomy tubes are methods of enteral nutrition in patients with functioning gastrointestinal tracts who cannot maintain adequate oral intake. Current placements; however, may be complicated by redundant wire and catheter loops within the stomach preventing operators from optimal feeding tube placement and predisposing patients to feeding tube prolapse. This report describes the occlusion balloon reduction technique for salvage of malpositioned tubes and placement of new enteric tubes in the setting of redundant loops.

MATERIALS AND METHODS

Five patients underwent the occlusion balloon reduction technique for jejunostomy (n = 3), gastrojejunostomy (n = 1), or nasojejunal tube placement (n = 1). All patients (n = 5) had redundant wires coiled within the stomach. In all patients (n = 5), a 9-French × 32 mm × 120 cm Coda balloon was inserted over the wire and passed into the small bowel. The balloon was inflated after which reduction of redundancy in the upper gastrointestinal tract was performed. Feeding tubes were then placed with tips in the distal jejunum. Technical success of the occlusion balloon reduction technique, successful placement of enteric tube, complications, and follow-up were recorded.

RESULTS

The occlusion balloon reduction was technically successful in all patients (n = 5). Feeding tube placement was successful in all patients (n = 5). No minor or major complication occurred. Mean follow-up was 56 days.

CONCLUSION

The occlusion balloon reduction technique provides a method for reduction of redundant wire and catheter loops within the stomach during enteric tube placement or repositioning.

Percutaneous Gastrostomy Tube Placement: Recognizing When Things Go Wrong

Percutaneous radiologic gastrostomy is a commonly performed, minimally invasive procedure for long-term enteral access in patients with a variety of conditions. Compared with other methods, it is less invasive, less costly, and safe, with a high technical success rate. The risk of complications is low, and most require only conservative management. Early, accurate diagnosis of more severe complication is crucial, as these may require prompt intervention. Therefore, radiologists should understand the imaging features, clinical presentation, and management of gastrostomy-related complications. This article will review the indications for long-term enteral access, discuss the available methods, summarize the percutaneous radiologic technique, and highlight the associated complications from gastrostomy placement.

Safety and Feasibility of Ultrasound-Guided Gastric Access for Percutaneous Transabdominal Gastrostomy Tube Placement

Background

The aim of the study was to evaluate the safety and feasibility of ultrasound guidance gastric access for percutaneous retrograde transabdominal gastrostomy (G)-tube placement.

Methods

Twenty-eight patients undergoing 31 percutaneous retrograde transabdominal G-tube placements utilizing ultrasound-guided gastric accesses were retrospectively identified.

Results

All patients had successful placement of G tubes with ultrasound-guided gastric access. There were no cases of aspiration or peritonitis. Average fluoroscopy time was 2.7 ± 1.4 min and average radiation dose was 220 ± 202 µGym².

Conclusions

Ultrasound-guided access for gastrostomy placement is safe and feasible and can be performed with minimal fluoroscopy times resulting in low patient and operator radiation dose.

Percutaneous gastric tube placement: Comparison of trans-abdominal and trans-oral approach in patients with chronic ascites

PURPOSE

The purpose of this study was to compare the trans-abdominal (TA) and trans-oral (TO) approaches for fluoroscopic-guided gastrostomy tube placement in patients with chronic ascites.

MATERIALS AND METHODS

A 10-year review of clinical imaging and medical records at a single institution identified 29 patients with chronic recurrent ascites who underwent gastrostomy (GT) or gastro-jejunostomy tube (GJT) placement. In 22 patients (18 women, 4 men) aged from 22 to 76 years of age (mean age, 57.7±13.1 years), a GT or GJT was placed with the TO approach, and in 7 (7 women) from 31 to 86 years of age (mean age, 63±16.8 years) with the TA approach.

RESULTS

Technical success was 100% in both groups with one (1/22; 5%) immediate complication in the TO group. Fluoroscopy time was significantly greater in the TO group (P=0.002). Leakage of ascites was significantly more frequent in the TA group (P=0.04). There was no significant difference in bleeding or inflammation (P=0.14 and P=0.43, respectively). The cumulative tract related complication rate was significantly greater in the TA group (P=0.03).

CONCLUSION

Fluoroscopy times and the overall incidence of tract-related complications, in particular leakage of ascites from the stoma, are more frequent in patients in chronic ascites who underwent TA gastrostomy tube placement compared to those who underwent TO placement.

Which G-Tube to Use in Pullers: Assessment of Pull Pressures on Skin Models to Determine Optimal Catheter Choice in Patients with Recurrent Pulled Gastrostomy Tubes

INTRODUCTION

Pulled or dislodged gastrostomy catheters represent a common complication associated with percutaneous gastrostomy and are a common cause of recurrent visits in patients with altered mental status. We intended to perform an experiment to compare the pull forces required to dislodge different commonly used gastrostomy catheters.

MATERIALS AND METHODS

We used a digital force gauge device to measure the pull forces required to dislodge three types of 20 French gastrostomy catheters in double-layer skin models. These included the Flow 20 Pull Method (Cook Medical, Bloomington, IN, USA), Entuit Gastrostomy BR Balloon Retention feeding tube (Cook Medical, Bloomington, IN, USA), and Ponsky Non-Balloon Replacement Gastrostomy Tube (CR Bard Inc, Salt Lake City, Utah, USA). The catheters were inserted into the skin model using the same technique as would be utilized in a patient.

RESULTS

The mean forces measured to dislodge the per-oral Flow 20 Pull Method, Entuit Thrive Balloon Retention, and button-type retention Ponsky replacement catheters were 35.6, 22.8, and 20.6 Newtons, respectively. The pull method per-oral gastrostomy catheter required significantly more pull force to dislodge than both the Ponsky button-type retention catheter and the Entuit balloon retention catheters. There was no significant difference in the pull force required to dislodge the Ponsky replacement catheter and the Entuit balloon retention catheter.

CONCLUSIONS

Per-oral image-guided gastrostomy with pull-method button-type retention catheters may be the ideal choice in patients at high risk of tube dislodgment.

Image-guided placement of percutaneous de novo low-profile gastrojejunostomy tubes in the pediatric population: a study of feasibility and efficacy

BACKGROUND

De novo low-profile gastrojejunostomy tubes in pediatric patients offer less external catheter bulk and decreased propensity for dislodgement as children become more mobile. While small cohort studies have evaluated de novo placement of coaxial, adjustable-length, percutaneous gastrojejunostomy (GJ) tubes in children, placement of de novo low-profile GJ tubes in pediatric patients has not been analyzed.

OBJECTIVE

This study evaluates technical feasibility, safety and clinical efficacy of percutaneous, retrograde placement of de novo low-profile GJ tubes in infants and children.

MATERIALS AND METHODS

Following institutional review board approval, all de novo low-profile GJ tube placements in patients were retrospectively reviewed between May 2014 and May 2017. Technical parameters of fluoroscopy time, tube size, T-fasteners and complications were recorded. Clinical data, including age, indication, weight gain and complications, were analyzed.

RESULTS

Thirty-four de novo low-profile GJ tubes were placed in 34 patients (median age: 9.4 months, range: 2 months-11.8 years; median pre-procedural weight: 7.5 kg, range: 2.9-31.6 kg). Twenty-one 14-Fr and 13 16-Fr GJ tubes were placed with technical success rate of 100%. Average weight gain 3 months' post procedure was 1.1 kg (range: 0.3-4.8 kg) and average weight percentile for age increase was 9.6% (range: -48.9% to 53.5%). One major complication occurred following balloon inflation within the tract causing pain requiring urgent replacement of the GJ tube. Minor complications occurred in 11 patients (32%): accidental dislodgement (n=9), skin irritation (n=4), tube dysfunction (n=2), leakage (n=2) and tube migration into the esophagus (n=1).

CONCLUSION

Percutaneous, antegrade, image-guided placement of de novo low-profile GJ tubes is technically feasible, safe and clinically efficacious in appropriately selected pediatric patients.

Push versus pull gastrostomy in cancer patients: A single center retrospective analysis of complications and technical success rates

PURPOSE

To compare the technical success and complication rates of push versus pull gastrostomy tubes in cancer patients, and to examine their dependence on operator experience.

MATERIALS AND METHODS

A retrospective review was performed of 304 cancer patients (170 men, 134 women; mean age 60.3±12.6 [SD], range: 19-102 years) referred for primary gastrostomy tube placement, 88 (29%) of whom had a previously unsuccessful attempt at percutaneous endoscopic gastrostomy (PEG) placement. Analyzed variables included method of insertion (push versus pull), indication for gastrostomy, technical success, operator experience, and procedure-related complications within 30 days of placement.

RESULTS

Gastrostomy tubes were placed for feeding in 189 patients and palliative decompression in 115 patients. Technical success was 91%: 78% after endoscopy had previously been unsuccessful and 97% when excluding failures associated with prior endoscopy. In the first 30 days, there were 29 minor complications (17.2%) associated with push gastrostomies, and only 8 minor complications (7.5%) with pull gastrostomies (P<0.05). There was no significant difference in major complications (push gastrostomy 5.3%, pull gastrostomy 5.6%). For decompressive gastrostomy tubes, the pull technique resulted in lower rates of both minor and major complications. There was no difference in complications or technical success rates for more versus less experienced operators.

CONCLUSION

Pull gastrostomy tube placement had a lower rate of complications than push gastrostomy tube placement, especially when the indication was decompression. The technical success rate was high, even after a failed attempt at endoscopic placement. Both the rates of success and complications were independent of operator experience.

Percutaneous Endoscopic Transgastric Jejunostomy (PEG-J) Tube Placement for Levodopa-Carbidopa Intrajejunal Gel Therapy in the Interventional Radiology Suite: A Long-term Follow-up

Background

Percutaneous endoscopic gastrojejunostomy (PEG) and radiologically inserted gastrojejunostomy (RIG) are both safe and effective techniques for gastrojejunal tube placement. The authors compared these 2 procedures in patients with advanced Parkinson's disease (PD) who required the continuous intrajejunal delivery of a levodopa/carbidopa gel suspension (LCIG).

Methods

Outcomes were retrospectively collated from 30 PEG and 12 RIG procedures performed at 2 centers in patients with advanced PD for the delivery of LCIG.

Results

Baseline clinical characteristics, incidence of early severe adverse events, late major complications, dropout, and the mean time-lapse of tube replacements were comparable in the PEG and RIG groups.

Conclusion

The current results suggest that, in patients with PD, the RIG technique is as safe and effective as the endoscopic procedure, and it can be considered a valid option for patients who require LCIG when the endoscopic procedure is not available or unfeasible.

Percutaneous radiologically guided gastrostomy tube placement: comparison of antegrade transoral and retrograde transabdominal approaches

PURPOSE

We aimed to compare the antegrade transoral and the retrograde transabdominal approaches for fluoroscopy-guided percutaneous gastrostomy tube (G-tube) placement.

METHODS

Following institutional review board approval, all G-tubes at two academic hospitals (January 2014 to May 2015) were reviewed retrospectively. Retrograde approach was used at Hospital 1 and both antegrade and retrograde approaches were used at Hospital 2. Chart review determined type of anesthesia used during placement, dose of radiation used, fluoroscopy time, procedure time, medical history, and complications.

RESULTS

A total of 149 patients (64 women, 85 men; mean age, 64.4±1.3 years) underwent G-tube placement, including 93 (62%) placed via the retrograde transabdominal approach and 56 (38%) placed via the antegrade transoral approach. Retrograde placement entailed fewer anesthesiology consultations (P < 0.001), less overall procedure time (P = 0.023), and less fluoroscopy time (P < 0.001). A comparison of approaches for placement within the same hospital demonstrated that the retrograde approach led to significantly reduced radiation dose (P = 0.022). There were no differences in minor complication rates (13%-19%; P = 0.430), or major complication rates (6%-7%; P = 0.871) between the two techniques.

CONCLUSION

G-tube placement using the retrograde transabdominal approach is associated with less fluoroscopy time, procedure time, radiation exposure, and need for anesthesiology consultation with similar safety profile compared with the antegrade transoral approach. Additionally, it is hypothesized that decreased procedure time and anesthesiology consultation using the transoral approach are likely associated with reduced cost.

Observation time after outpatient non-arterial interventional procedures: standards, safety, and outcomes

PURPOSE

To evaluate the impact of standardized reduced post-procedure observation time on subsequent healthcare encounters such as emergency department (ED) visits, hospital admissions, and clinic visits.

METHODS

800 consecutive patients undergoing outpatient non-arterial interventional radiologic procedures within the vascular interventional department between 1 June 2013 and 21 July 2014 were included in this IRB-approved, HIPAA-compliant single center observational retrospective study. Electronic medical records were reviewed for subsequent healthcare encounters, such as ED visits, hospital admissions, and clinic visits. An attending interventional radiologist and radiology resident reviewed, in consensus, medical records for relevance of the encounter to the index procedure. Procedure-related encounters were analyzed to determine relationship to length of observation time, using Matlab for statistical analysis.

RESULTS

397 and 403 patients were in the pre- and post-standardization groups, respectively. Median observation time decreased overall from 1.67 h [interquartile range (IQR) 1.17-2.17] to 1.42 h (IQR 1.08-1.92), p < 0.001. There was no significant change in either overall or procedure-related ED visits (16.6% [66/397] and 1.0% [4/397] pre-standardization vs. 20.1% [81/403] and 2.2% [9/403] post-standardization, p = 0.24 and 0.26), hospital admissions (27.7% [110/397] and 4.0% [16/397] prestandardization vs. 28.3% [114/403] and 2.7% [11/403] post-standardization, p = 0.88 and 0.33), or clinic visits (41.3% [164/397] and 1.0% [4/397] pre-standardization vs. 39.5% [159/403] and 2.2% [9/403] post-standardization, p = 0.61 and 0.26).

CONCLUSION

Proposed standardized shortened observation times after outpatient interventional radiologic procedures are safe, without change in either total or procedure-related ED visits, hospital admissions, or clinic visits.

When Is Parenteral Nutrition Appropriate?

Parenteral nutrition (PN) represents one of the most notable achievements of modern medicine, serving as a therapeutic modality for all age groups across the healthcare continuum. PN offers a life-sustaining option when intestinal failure prevents adequate oral or enteral nutrition. However, providing nutrients by vein is an expensive form of nutrition support, and serious adverse events can occur. In an effort to provide clinical guidance regarding PN therapy, the Board of Directors of the American Society for Parenteral and Enteral Nutrition (ASPEN) convened a task force to develop consensus recommendations regarding appropriate PN use. The recommendations contained in this document aim to delineate appropriate PN use and promote clinical benefits while minimizing the risks associated with the therapy. These consensus recommendations build on previous ASPEN clinical guidelines and consensus recommendations for PN safety. They are intended to guide evidence-based decisions regarding appropriate PN use for organizations and individual professionals, including physicians, nurses, dietitians, pharmacists, and other clinicians involved in providing PN. They not only support decisions related to initiating and managing PN but also serve as a guide for developing quality monitoring tools for PN and for identifying areas for further research. Finally, the recommendations contained within the document are also designed to inform decisions made by additional stakeholders, such as policy makers and third-party payers, by providing current perspectives regarding the use of PN in a variety of healthcare settings.

The PEG-Pedi-PEG technique: a novel method for percutaneous endoscopic gastrojejunostomy tube placement (with video)

BACKGROUND AND AIMS

When PEG tube feeding is complicated by anatomic obstruction, dysmotility, or aspiration, a need arises for feeding beyond the pylorus. The currently available percutaneous gastrojejunostomy (PEG-J) kits have issues with the jejunal extension portion migrating back into the stomach. The aim of this study was to evaluate the feasibility and safety of a novel technique that creates PEG-J tubes by combining an adult percutaneous gastrostomy (PEG) tube with a pediatric PEG tube, the PEG-Pedi-PEG procedure.

METHODS

This was a retrospective study at a single tertiary care center. The main outcome measures were success of placement, rate of retrograde tube migration, early (<24 h after procedure was performed) and late (>24 h after procedure was performed) adverse events.

RESULTS

Seventeen patients underwent PEG-Pedi-PEG procedures during the study period. Technical success was achieved in all patients (100%). The retrograde migration rate of the jejunal extension tube was 0%. Early adverse events included peristomal pain in 1 patient. Late adverse events included inadvertent tube removal (3 patients), diarrhea (1 patient), prolonged ileus/gastroparesis (1 patient), and tube occlusion (1 patient). Mean follow-up was 290 days.

CONCLUSIONS

The PEG-Pedi-PEG procedure is a novel endoscopic technique to facilitate post-pyloric feeding because the pediatric PEG bumper may act like a sail in the small bowel, with peristalsis pushing the bumper distally and thus decreasing the possibility of migration back into the stomach. This study demonstrated excellent technical success, no retrograde migration, and a low rate of adverse events.

Percutaneous radiologic gastrostomy catheter placement without gastropexy: a co-axial balloon technique and evaluation of safety and efficacy

PURPOSE

The purpose of this study is to evaluate the short-term safety and efficacy of a co-axial angioplasty balloon technique for percutaneous radiologic gastrostomy catheter placement (PRG).

METHODS

A total of 65 percutaneous radiologic gastrostomy tube placements were performed with the co-axial angioplasty balloon technique from 10/1999 to 1/2014. This included 19 females and 46 males between the ages of 20-83. Without the use of T-fasteners for gastropexy, the gastrostomy tube was placed over a catheter-shaft angioplasty balloon as a co-axial system. The angioplasty balloon was used to sequentially approximate the stomach wall to the abdominal wall, dilate the tract, and was then used as a dilator to aid gastrostomy tube advancement into the gastric lumen. Technical success, complications, and dislodgements were evaluated by means of retrospective review of patient medical records and imaging.

RESULTS

There was no procedural failure in any of the 65 placements. 30-day follow-up was available for 56 patients. 7 patients died within 30 days; none of the deaths were recorded as procedure-related. There was 1 major complication (1.5%) consisting of a colocutaneous fistula. There were 4 minor complications (6.2%). There was no occurrence of bleeding or skin infection while using this technique.

CONCLUSIONS

PRG with the co-axial angioplasty-balloon technique is a safe and effective technique for gastrostomy placement.

CIRSE Standards of Practice Guidelines on Gastrostomy

PURPOSE

Surgical Gastrostomy has been around since the 19th century but in 1980 the first successful percutaneous endoscopic gastrostomy was reported. A year later the first successful percutaneous gastrostomy was performed using fluoroscopic guidance. The technique for percutaneous insertion and the equipment used has been refined since then and it is now considered the gold standard for gastrostomy insertion. Here we present guidelines for image-guided enteral feeding tubes in adults.

MATERIAL AND METHOD

We performed a review and analysis of the scientific literature, other national and international guidelines and expert opinion.

RESULTS

Studies have shown fluoroscopic techniques have consistently higher success rates with lower rates of major complications than endoscopic techniques. However, the Achilles' heel of many fluoroscopic techniques is the requirement for smaller gastrostomy tube sizes resulting in them being more prone to blockages and thus requiring further intervention.

CONCLUSION

Radiological feeding tube insertion is a safe and effective procedure. Success rates are higher, and complication rates lower than PEG or surgical gastrostomy tube placement and innovative techniques for gastric and jejunal access mean that there are very few cases in which RIG is not possible. The principal weakness of radiologically inserted gastrostomies is the limitiation on tube size which leads to a higher rate of tube blockage. Per-oral image-guided gastrostomies have to an extent addressed this but have not been popularised. Currently many centres still consider endoscopic gastrostomies as the first line unless patients are too unwell to undergo this procedure or previous attempts have failed, in which case radioloically inserted gastrostomies are the technique of choice.

Safety and Short-Term Complication Rates Using Single-Puncture T-Fastener Gastropexy

PURPOSE

To report a single operator's experience using a modified single-puncture gastrostomy technique deploying up to three nonabsorbable gastropexy anchors.

MATERIALS AND METHODS

A retrospective review of 69 consecutive patients undergoing gastrostomy, gastrojejunostomy, or jejunostomy tube insertion between March 2012 and January 2014 was performed. Technical success and 30-day local, major, and minor complication rates were assessed according to the Society of Interventional Radiology (SIR) Standards of Practice for Gastrointestinal Access. Procedure time was also recorded.

RESULTS

Primary technical success of the procedure was 98.6% (68/69). In one patient, the procedure was aborted because the stomach could not be safely accessed. Major complications occurred in one of 69 (1.4%) patients, minor complications occurred in 10 of 69 (13%) patients, and local complications occurred in three of 69 (4.3%) patients. Local complications consisted of redness and mild tenderness at the enteric access site. Mean procedure time was 5 minutes (range, 3.1-36 min).

CONCLUSIONS

Single-puncture, multianchor gastrostomy is a feasible technique for radiologically guided enteric access tube insertion with technical success and complication rates similar to conventional gastrostomy techniques. This technique could be considered when expeditious performance of a procedure is required.

Diagnosis and management of hemorrhagic complications of interventional radiology procedures

Image-guided interventions have allowed for minimally invasive treatment of many common diseases, obviating the need for open surgery. While percutaneous interventions usually represent a safer approach than traditional surgical alternatives, complications do arise nonetheless. Inadvertent injury to blood vessels represents one of the most common types of complications, and its affect can range from inconsequential to catastrophic. The interventional radiologist must be prepared to manage hemorrhagic risks from percutaneous interventions. This manuscript discusses this type of iatrogenic injury, as well as preventative measures and treatments for postintervention bleeding.

Retrograde gastrojejunostomy tube migration

Percutaneous enteral feeding tubes are placed about 250,000 times each year in the United States. Although they are relatively safe, their placement may be complicated by perforation, infection, bleeding, vomiting, dislodgment, and obstruction. There have been numerous reports of antegrade migration of gastrojejunostomy (G-J) tubes. We report a case of G-J tube regurgitation following protracted vomiting and discuss the management of this very rare entity.

Early initiation of enteral feeding in cancer patients after outpatient percutaneous fluoroscopy-guided gastrostomy catheter placement

PURPOSE

To report the results of early enteral feeding in patients with cancer after outpatient placement of a percutaneous fluoroscopy-guided gastrostomy (PFG).

MATERIALS AND METHODS

From January 2008 through December 2008, 121 consecutive patients with cancer underwent outpatient placement of a PFG for nutrition. Of these patients, 118 patients met criteria for early feeding, and 113 were successfully fed early (after at least 3 hours). Of the patients fed early, 5 had insufficient follow-up for further analysis leaving 108 patients for outcomes analysis. After placement of the PFG, patients were put on low-wall suction via the PFG for 1 hour followed by feeding via the PFG at least 3 hours after placement. Follow-up evaluation was done the next business day. The medical records were reviewed for 30-day outcomes of early feeding, technical aspects of the procedures, and complications.

RESULTS

After placement of the PFG, 98% (118 of 121) of patients met criteria for early feeding, and 93% (113 of 121) of patients were successfully fed early. The median time between the end of the procedure and initiation of feeding was 4 hours (interquartile range, 3.7-4.4 h). The 30-day minor complication rate was 14% (15 of 108), and the 30-day major complication rate was 1% (1 of 108). No complications were directly attributable to early feeding.

CONCLUSIONS

Early initiation of tube feedings after outpatient placement of a PFG was well tolerated in patients with cancer and carried comparable risks to previously reported results using traditional delayed feeding protocols. Early feeding provided patients with prompt enteral nutrition and eliminated the need for routine hospital admission after the procedure.

Comparison of primary jejunostomy tubes versus gastrojejunostomy tubes for percutaneous enteral nutrition

PURPOSE

To evaluate technical success and long-term outcomes of percutaneous primary jejunostomy tubes for postpyloric enteral feeding compared with percutaneous gastrojejunostomy (GJ) tubes.

MATERIALS AND METHODS

Over a 25-month interval, 41 consecutive patients (26 male; mean age, 55.9 y) underwent attempted fluoroscopy-guided direct percutaneous jejunostomy tube insertion. Insertions at previous jejunostomy tube sites were excluded. The comparison group consisted of all primary GJ tube insertions performed over a 12-month interval concomitant with the jejunostomy tube interval (N = 169; 105 male; mean age, 59.4 y). Procedural, radiologic, and clinical data were retrospectively reviewed. Intervention rates were expressed as events per 100 catheter-days.

RESULTS

The technical success rate for percutaneous jejunostomy tube insertion was 96%, versus 93% for GJ tubes (P = .47). Mean fluoroscopy times were similar for jejunostomy and GJ tubes (9.8 vs 10.0 min, respectively; P value not significant). Jejunostomy tubes exhibited a lower rate of catheter dysfunction than GJ tubes, with catheter exchange rates of 0.24 versus 0.93, respectively, per 100 catheter-days (P = .045). GJ tube tip retraction into the stomach occurred in 9.5% of cases, at a rate of 0.21 per 100 catheter-days. Intervention rates related to leakage were 0.19 and 0.03 for jejunostomy and GJ tubes, respectively (P < .01). Jejunostomy and GJ tubes exhibited similar rates of catheter exchange for occlusion and replacement as a result of inadvertent removal. No major complications were encountered in either group.

CONCLUSIONS

Percutaneous insertion of primary jejunostomy tubes demonstrated technical success and complication rates similar to those of GJ tubes. Jejunostomy tubes exhibited a lower dysfunction rate but a higher leakage rate compared with GJ tubes.
