Complications Associated With Primary Placement of Gastrostomy for Feeding

Study Overview
=================
Brief Summary
-----------------
The purpose of the study is to compare pain, complications, and quality of life after gastrostomy tube is placed by either percutaneous endoscopic gastrostomy (PEG) or radiologically-inserted gastrostomy (RIG) method.

Detailed Description
-----------------
Objectives: Primary objectives: to assess 1) pain and 2) major and minor complications with gastrostomy-tube placement, comparing RIG with PEG Secondary objectives: To compare costs associated with each technique To compare anesthesia type used with each technique To assess patient quality of life before and after the procedure Co-primary outcome measures: Efficacy Outcome - Trajectory of the average pain score (question 3, Cleeland Brief Pain Inventory) through Week 6 Statistical Null Hypothesis: The model-based estimates of the pain scores trajectories will be co-incident for the two placement approaches RIG compared to PEG. Safety Outcome - Minor and major complication rate per participant Statistical Null Hypothesis: The percentage of participants with at least one major or minor complication will be equal between RIG and PEG groups Methods: All participants meeting criteria for placement of gastrostomy tube for nutrition and not having any exclusion criteria will be prospectively randomized at the initial Home Enteral Nutrition (HEN) visit with physician, nurse and dietician. The randomization will be performed with the use of a 4-block randomization tool, based on the inclusion criteria and will not be intentionally matched for other demographics. Participants will be randomized to either undergo RIG with an Interventional Radiologist or PEG with a Gastroenterologist. Sixty-four participants will be randomized into each group for a total accrual of 128 patients. Participants will be randomized to receive one of two widely-accepted standards of care. The research component will involve the use of questionnaires during routine post-placement follow-up to assess for pain, quality of life, and complications. Radiologic technique: Radiologically-inserted gastrostomy (RIG) tubes are placed in one of three ways: either using 1) a balloon to dilate the tract without gastropexy T-fasteners, 2) a balloon to dilate the tract with gastropexy T-fasteners or 3) a peel-away sheath with gastropexy T-fasteners. All of the procedures occur in the interventional radiology procedural suite and are performed after informed consent is obtained. The participant receives weight-based antibiotics intravenously. A temporary small nasogastric or orogastric tube is placed if one is not in place. Suitable site for percutaneous access into the stomach is localized on the abdomen, sometimes with the use of ultrasound to mark the liver edge. Participants may or may not have had a CT scan of the abdomen for stomach localization prior to the placement. The abdomen is prepped and draped in the usual sterile fashion. Local anesthesia alone or with the addition of moderate sedation, monitored anesthesia care, or general anesthesia is administered, depending on the needs of the participant. Participant may or may not receive intravenous glucagon. Air is insufflated into the stomach through the nasogastric tube under fluoroscopic guidance. One percent lidocaine for local anesthesia is instilled at the desired gastrostomy site and at the sites of T-fasteners, if used. An 18-gauge or micropuncture needle is advanced into the insufflated stomach under fluoroscopic guidance. Air is aspirated, and contrast medium is injected to confirm the intraluminal location of the needle(s). A stiff guidewire is advanced into the stomach or through the stomach to the ligament of Treitz. For the balloon-dilatation technique, the tract is dilated with a balloon, the gastrostomy tube is advanced into the stomach using the balloon in coaxial fashion, and then the dilating balloon is removed. For the technique that uses a peel-away sheath, the tract is serially dilated over the wire, and a peel away sheath is advanced over the wire into the stomach. For both techniques, a 16- or 18-French balloon-style gastrostomy tube is then advanced into the stomach lumen, and the guide wire is removed. If T-fasteners are used, they are then secured to the participant's skin. T-fasteners are designed to fall off at six weeks. The nasogastric tube is removed at the end of the procedure. Participants may use the tube for water and medications at two hours and may use the tube for feedings no sooner than four hours, but only after appropriate Home Enteral Nutrition follow-up. Endoscopic technique: All PEG placements are performed with anesthesia support and after informed consent is obtained. After the participant is appropriately sedated and antibiotic prophylaxis is given, the standard adult gastroscope is passed orally and a routine esophagogastroduodenoscopy (EGD) is performed to assess for any unknown pathology and to characterize if appropriate apposition of the anterior gastric wall and the abdominal wall can be accomplished. This requires insufflation of air or carbon dioxide through the scope and then palpation of the abdominal wall and/or observation of the abdominal wall for light trans-illumination to identify the site of best apposition of the two walls. This site is marked and then cleansed. Local lidocaine is infiltrated and a small stab wound may be made at the discretion of the endoscopist. Using sterile technique a needle is passed through the abdominal wall into the gastric lumen as observed endoscopically. Through this needle is passed a looped flexible wire which is grasped with a snare introduced through the scope and the wire is withdrawn out the mouth as the scope is removed. A 20-French gastrostomy tube is attached to the looped wire and the wire is pulled from the abdominal wall so the tube is pulled through the mouth and down the esophagus into the stomach and out the abdominal wall. The tube is pulled into position until the inner bumper is noted to be at the abdominal wall. The faceplate is then placed over the external tube to maintain position. At the discretion of the endoscopist the scope may be passed once more into the stomach to ensure proper positioning of the tube. The tube may be used for fluid or feedings at 4 hours after initial placement, but only after appropriate Home Enteral Nutrition follow-up. Independent of whether RIG or PEG is placed, the participants will be followed by the Home Enteral Nutrition clinic, using the following protocol: Face-to-face visit with HEN nurse for site care and tube education and with HEN dietitian for instruction about provision of supplies and for administration of the first feeding together, to occur within 24 hours post-procedure. Phone call or secure message at 48-86 hours post-procedure to answer questions and ensure proper progression of feeding. Phone call or secure message or face-to-face visit 6 weeks post-procedure. Face-to-face visit with HEN dietitian and nurse for tube exchange, at 3 months for RIG and 9 months for PEG, if needed, for first tube replacement. Length of study: Participants will be followed until tube removed or until 9 months, whichever is shorter. Data Collection: Study data collected will include pain, major and minor complications, quality of life, rates of early exchange of tube, and costs associated with each procedure.
