Ultrasound-guided gastrostomy tube placement: A case series.

PURPOSE: Gastrostomy tubes (G-tubes) can be placed utilizing a variety of techniques. Here we present a case series to demonstrate feasibility of a novel method, ultrasound-guided G-tube placement (USGTP).

METHODS: All cases of USGTP at our institution from September 2015-August 2016 were reviewed. Data included demographics, operative time, complications, time to first feeding, and 30-day readmissions. All steps of the procedure were carried out using ultrasound guidance, resulting in placement of a low-profile G-tube.

RESULTS: Twelve patients underwent USGTP. Median age at operation was 2.6years (IQR 0.9-5.3) and median weight 9.9kg (IQR 7.2-18.4). Median operative time was 27min. (IQR 20-44). First feeding occurred 8.8±2.9h after the procedure. The second patient in the series experienced the only operative complication. In this case, a linear probe was used with insufficient gastric distension, resulting in placement of the tube through a fold in the stomach wall. This was recognized and remedied intraoperatively. This prompted successful technique modification for future USGTPs. Only one patient was readmitted within 30days, and this was related to urinary retention, an underlying problem.

CONCLUSION: US-guided G-tube placement appears initially to be safe, efficient and effective. Advantages include good anatomical delineation, a single incision, initial placement of a low-profile G-tube, and avoidance of endoscopy, laparoscopy, and radiation. This report illustrates feasibility of USGTP paving the way for further investigation and comparison to other existing gastrostomy insertion methods.
