Abstract
Introduction: Insecure gastropexy, gastric mucosa overgrowth, granulation tissue formation, and a nonhealing gastrostomy are unwanted consequences encountered in the current minimally invasive gastrostomy tube (GT) placement techniques. Aiming to overcome these problems we have developed a simplified laparoscopic-assisted GT insertion (LAG) procedure using guided transabdominal U-stitches (GTU) gastropexy.
Materials and Methods: We retrospectively reviewed all LAG cases performed in our institute using the GTU technique. In brief, a curved clamp is inserted intragastrically through the laparoscopic port and guides a needle across the abdominal and gastric walls to exit, then re-enter back, through the port in an out-in-out fashion creating multiple spaced transabdominal U-stitches that are tied over pledgets.
Results: Between March 2008 and January 2015, 31 cases had LAG attempted using GTU. Two cases were converted to open procedures for non-LAG-related reasons. The median age of the remaining 29 cases was 37 (range, 0.3-154.9) months. Of those patients, 20 had fundoplication (LAG-Fundo), whereas the remaining 9 had LAG-only. The mean operative times for LAG-Fundo and LAG-only were 148 +/- 57.5 minutes and 41 +/- 12.4 minutes, respectively. During a median follow-up of 21 (range, 4-81) months we did not encounter any procedure-related mortality, intraabdominal leaks, or bowel injuries. One patient required redo gastropexy due to unplanned early U-stitch removal, and 7 cases had transient external GT leak, granuloma formation, and/or skin infection.
Conclusions: GTU can achieve a simple and secure LAG, avoiding the catastrophic complications of intraabdominal leak without the need of special instruments or enlarging the port's wound. Using a smaller wound and intraabdominally placed mucosa helps in minimizing the risk of wound infection and external leak. Transient complications are expected during the earlier phase of the learning curve.
