T-fastener migration after percutaneous gastropexy for transgastric enteral tube insertion

Percutaneous radiologic gastrostomy with single gastropexy using balloon-assisted tract dilatation: comparison with peel-away sheath

PURPOSE

To evaluate the safety and efficacy of percutaneous radiologic gastrostomy (PRG) with balloon-assisted tract dilatation (BATD) using a single gastropexy.

METHODS

This retrospective study was approved by the institutional review board. From August 2018 to October 2022, 61 patients (53 male and 8 female, mean age 67 years, age range 27-90 years) underwent PRG with balloon-retained tubes for enteral nutrition. Single gastropexy was performed in all cases. Patients were divided into two groups based on the tract dilatation technique used. In the first group, BATD (n = 48) was performed. In the second group, a 24-Fr peel-away sheath (PAS) was used for tract dilatation (n = 13). Patient demographics, technical success rate, clinical success rate, fluoroscopy time, cumulative radiation dose, and complications were retrospectively evaluated. The Mann-Whitney U test for continuous variables and Fisher's exact test for categorical variables were performed to compare the two groups.

RESULTS

All procedures were successfully performed with 100% technical and clinical success rates in both groups. The mean fluoroscopy time for the BATD group vs. the PAS group (1.68 ± 0.93 min vs. 3.56 ± 2.41 min, P < 0.001) and mean cumulative radiation dose (12.98 ± 9.28 mGy vs. 33.01 ± 15.14 mGy, P < 0.001) were significantly lower in the BATD group compared with the PAS group. There was one major complication of peritonitis that led to death in the PAS group (1/13, 7.7%) and no major complications in the BATD group. Minor complications such as pneumoperitoneum, abdominal pain, leakage, and balloon deflation occurred in 16 patients: 12 (12/48, 25.0%) patients in the BATD group and 4 (4/13, 38.5%) patients in the PAS group. The overall rate of major and minor complications was higher in the PAS group but did not show statistically significant differences (odds ratio: 1.875, 95%; confidence interval: 0.514-6.841, P = 0.486).

CONCLUSION

BATD using a single gastropexy is a safe and effective technique for PRG.

Choosing wisely: Enteral feeding tube selection, placement, and considerations before and beyond the procedure room

When an enteral feeding tube (EFT) is placed, it is not always known how long this nutrition support intervention will be needed. As a result, the type of device the patient originally has placed may not match the function it is required to serve or the lifestyle needs of the patient throughout their enteral nutrition journey. Medicare considers an EFT a prosthetic device, as it is replacing a permanently inoperable or nonfunctioning organ. If we think about an EFT the same way we think about a prosthetic limb, one that needs to be customized to meet all of the patient's functional and lifestyle needs, we can also begin to think beyond the procedure room and carefully consider a variety of factors that impact the patient at home receiving enteral nutrition. Proper fit, function, and style is essential in order for the patient to have a positive relationship with their EFT, contributing to their successful home enteral nutrition experience. Clinicians who care for these patients in any setting and in any capacity would benefit from enhancing their understanding of available EFT options, their design components, and available methods of placement. Many home care and outpatient clinicians adopt the role of patient advocate as it relates to a patient's enteral nutrition journey, and this expanded knowledge could be used to benefit the patient by improving their overall enteral nutrition experience and ultimately their relationship with their "prosthetic."

Safety and efficacy of laparoscopy-assisted percutaneous endoscopic gastrostomy in infants and small children weighing less than 10 kg: A comparison with larger patients

INTRODUCTION

Laparoscopy-assisted percutaneous endoscopic gastrostomy (LAPEG) can reduce the risk of percutaneous endoscopic gastrostomy-related complications, such as intra-abdominal organ injury, and determine the optimal position for placement of the gastrostomy tube. We first employed LAPEG 10 years ago but limited its application to elderly patients. Indications for LAPEG have now expanded to small children. This retrospective study aimed to determine the feasibility of LAPEG in children weighing <10 kg.

METHODS

Our LAPEG procedure for small children involves three essential techniques: gastric insufflation with CO₂ to prevent intestinal dilation, a T-fastener device to overcome the difficulties of gastropexy, and primary placement of a button gastrostomy to create less torque than tube gastrostomy at the insertion site and to prevent early tube dislodgement. The medical records of 48 patients with physical and mental disabilities who underwent LAPEG between 2010 and 2018 were evaluated. The outcomes of LAPEG in patients weighing <10 kg (group A, n=11) and ≥10 kg (group B, n=37) were compared.

RESULTS

The LAPEG procedure was completed in all cases without intraoperative complications or open conversion. The median bodyweight of group A was 6.3 kg (range, 3.6-8.2 kg). None of the patients in group A developed postoperative complications such as stomal infection or dislodgement. The operative time was significantly shorter in group A than in group B (P < .05).

CONCLUSION

By improving surgical techniques for small children, our LAPEG procedure might be feasible and safe for treating children weighing <10 kg, including those weighing as little as 3.6 kg.

Gastrostomy: A percutaneous laparoscopic technique

Several techniques are available for a gastrostomy concomitant with a major abdominal surgery, i.e., there is no 'standard' technique. Here, we present our results of a novel concomitant gastrostomy developed for the Nissen fundoplication. It combines the laparoscopic instrumentation with the kit for percutaneous endoscopic gastrostomy. Once the fundoplication is completed, the gastrostomy is performed in three stages. First, with the orogastric tube and snare, the loop of wire is left in the peritoneal cavity; next, a guide-wire introduced into the peritoneal cavity from the abdominal wall, is taken with the loop, and retrieved at the mouth; finally, the gastrostomy tube is pulled with the guide-wire from mouth to abdominal wall. Only laparoscopic instrumentation is used to choose the site in the stomach, and to perform the puncture; hence, the gastroscope is unnecessary. By choosing the proper sites, stomata are aligned and free of lateral strains making the gentle pressure of the dome enough to appose gastric and abdominal walls; hence, stitches become unnecessary to affix the walls. This percutaneous laparoscopic gastrostomy is simple, brief (ca 21 min), well tolerated, without complications during the intervention or the postoperatory period, reproducible, and of low cost, and exceptional skills are not required. Finally, laparoscopic protocols for a primary gastrostomy may dispel some complications by choosing a 'pull' to install the gastrostomy tube as reported here, instead of the usual 'push'.

Alexis St. Martin Gastropexy: A Novel Technique for Gastropexy During Percutaneous Endoscopic Gastrostomy Tube Placement

BACKGROUND

Percutaneous endoscopic gastrostomy (PEG) is a preferred method of long-term enteral nutritional support. Despite its ease of placement, it has a 4% major complication rate, requiring surgical intervention or hospitalization. Early PEG tube dislodgment can cause peritonitis, requiring emergent laparotomy at significant morbidity and cost. T-fasteners have been used as an adjunct gastropexy, but nearly one third migrate into the abdominal wall within the first 2 weeks. We describe a low-cost, minimally invasive technique using widely available surgical instruments to appose the gastric and abdominal walls.

METHODS

All PEG procedures were performed in our 60-bed surgical intensive care unit. Institutional IRB approval was obtained along with procedure specific consent for all patients. The adjunctive gastropexy procedure was performed on four patients at high risk for early PEG tube dislodgment. Following routine PEG tube placement, both ends of four 2-0 polyglactin ties were brought through the gastric and abdominal walls through separate stab incisions adjacent to the PEG tube exit site in the 3, 6, 9, and 12 o'clock positions. These were tied in the subcutaneous tissue, securing the gastric wall to the abdominal wall.

RESULTS

No PEG tube complications occurred. All patients were discharged to long-term care facilities with PEG tubes intact or electively removed.

CONCLUSIONS

We describe the results of a pilot study for a cost-effective, easily implementable, adjunct technique, named after the namesake of our institution, to decrease the incidence and severity of complications associated with PEG tube dislodgment. It was used in 4 patients at high risk for PEG tube dislodgment with satisfactory early results in all 4. Further recruitment of larger numbers of patients using this technique is ongoing to determine if this technique is truly effective at reducing PEG tube complications.

Initial experience with percutaneous endoscopic gastrostomy with T-fastener fixation in pediatric patients

BACKGROUND AND STUDY AIMS

 Insertion of a percutaneous endoscopic gastrostomy (PEG) with push-through technique and T-fastener fixation (PEG-T) has recently been introduced in pediatric patients. The T-fasteners allow a primary insertion of a balloon gastrostomy. Due to limited data on the results of this technique in children, we have investigated peri- and postoperative outcomes after implementation of PEG-T in our department.

PATIENTS AND METHODS

 This retrospective chart review included all patients below 18 years who underwent PEG-T placement from 2010 to 2014. Main outcomes were 30-day postoperative complications and late gastrostomy-related complications.

RESULTS

 In total, 87 patients were included, and median follow-up time was 2.4 years (1 month - 4.9 years). Median age and weight at PEG-T insertion were 1.9 years (9.4 months - 16.4 years) and 10.4 kg (5.4 - 33.0 kg), respectively. Median operation time was 28 minutes (10 - 65 minutes), and 6 surgeons and 3 endoscopists performed the procedures. During the first 30 days, 54 complications occurred in 41 patients (47 %). Most common were peristomal infections treated with either local antibiotics in 11 patients (13 %) or systemic antibiotics in 11 other patients (13 %). 9 patients (10 %) experienced tube dislodgment. Late gastrostomy-related complications occurred in 33 patients (38 %). The T-fasteners caused early and late complications in 9 (10 %) and 11 patients (13 %), respectively. Of these, 4 patients (5 %) had subcutaneously migrated T-fasteners which were removed under general anesthesia.

CONCLUSION

 We found a high rate of complications after PEG-T. In particular, problems with the T-fasteners and tube dislodgment occurred frequently after PEG-T insertion.

Head and Neck Cancer Tumor Seeding at the Percutaneous Endoscopic Gastrostomy Site

The National Institutes of Health National Cancer Institute estimates that over 13,000 new cases of head and neck cancer (HNC) will be diagnosed in 2017. Patients with HNC often require enteral nutrition (EN) via gastrostomy tube to provide nutrition support and hydration because of tumor obstruction of the oropharynx and/or cumulative effects of chemoradiation therapy. The percutaneous endoscopic gastrostomy (PEG) tube has become the preferred technique for EN access because placement is considered a minimally invasive procedure. There are 3 methods of PEG placement: Gauderer-Ponsky "pull," Sachs-Vine "push," and Russell "push" method. The Gauderer-Ponsky "pull" method has become the preferred method of PEG placement. It has been previously reported that the rate of stomal metastasis can be 0.5%-1% of those undergone the Gauderer-Ponsky "pull" method that is consistent with HNC morphology. Other researchers believe the rate may be as high as 0.5%-3%. This article reviews the 3 methods of PEG placement, as well as all potential complications, including metastatic seeding at the PEG site. In addition, 1 additional case of tumor seeding at the PEG site will be reviewed. Consideration for avoidance of the Gauderer-Ponsky pull method of PEG placement or other methods of feeding tube placement where the gastrostomy tube has to pass through the oral cavity before exiting the abdominal wall in patients with squamous cell carcinoma of the head and neck should be considered.

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.

Description and Biomechanical Comparison of a Percutaneous Radiologic Gastropexy Technique in a Canine Cadaver Model

OBJECTIVE

To describe a novel percutaneous radiologic gastropexy (PRG) technique in a canine model and to biomechanically compare this technique to open incisional gastropexy (OIG) and laparoscopic-assisted incisional gastropexy (LAG).

STUDY DESIGN

Randomized ex vivo biomechanical study.

ANIMALS

Canine cadavers.

METHODS

Fifteen cadavers were randomized to 1 of 3 surgical interventions: OIG, LAG, and PRG. For the PRG procedure, the stomach was distended with air, and a preloaded T-fastener device was utilized to attach the stomach to the body wall with fluoroscopic-guidance. The procedural times of the 3 techniques were recorded. After completion of the procedure, the stomach and body wall overlying the stomach wall were harvested and the maximum tensile strength of the gastropexies was determined.

RESULTS

The maximal tensile strength was not significantly different between groups. The total procedural time for the PRG procedure (5 minutes) was significantly shorter than both OIG (28 minutes) and LAG (20 minutes) procedures.

CONCLUSION

The PRG technique described in this study demonstrated a similar maximal tensile strength to commonly employed gastropexy techniques (OIG and LAG) in an acute canine model. Additionally, the PRG procedure was significantly faster to perform. The clinical relevance of this technique will be determined by further study to assess the applicability and efficacy of this procedure in clinical patients by determining the likelihood of adhesion development and the ability of the adhesion to prevent gastric volvulus.

Management of dysfunctional catheters and tubes inserted by interventional radiology

Minimally invasive percutaneous interventions are often used for enteral nutrition, biliary and urinary diversion, intra-abdominal fluid collection drainage, and central venous access. In most cases, radiologic and endoscopic placement of catheters and tubes has replaced the comparable surgical alternative. As experience with catheters and tubes grows, it becomes increasingly evident that the interventional radiologist needs to be an expert not only on device placement but also on device management. Tube dysfunction represents the most common complication requiring repeat intervention, which can be distressing for patients and other health care professionals. This manuscript addresses the etiologies and solutions to leaking and obstructed feeding tubes, percutaneous biliary drains, percutaneous catheter nephrostomies, and drainage catheters, including abscess drains. In addition, we will address the obstructed central venous catheter.
