Laparoscopic-assisted Stamm-gastrostomy: technical modifications to ease suturing inside the minimal trocar site

摘要

Laparoscopic gastrostomy tube placement has been increasingly adopted by pediatric surgeons. We herein report our experience with the performance of a laparoscopic-assisted Stamm-operation inside the minimal trocar site without the extension of the trocar site incision or mini-laparotomy. We present some technical modifications that facilitate suturing inside the minimal trocar site. Methods A retrospective chart review was conducted of cases involving patients who underwent laparoscopic-assisted gastrostomy, using a simple extracorporeal method inside the trocar site from April 1998 to March 2018. Results One hundred five gastrostomy tubes were placed in a laparoscopic-assisted operation. All but two of the cases involved patients with neurological impairment. The mean age was 12.5 years; 28 cases were > 16 years of age. Seventy-five cases underwent gastrostomy during laparoscopic fundoplication. All gastrostomy procedures were completed without intraoperative difficulties; however, 8 cases, which involved a thick abdominal wall, required extension of the trocar site. No cases required conversion to open gastrostomy. No major complications were observed. Two patients developed continuous peristomal cellulitis after surgery, due to the mismatch of the site position and an unsuitable button device size. Conclusion We demonstrated that laparoscopic gastrostomy with fully extracorporeal suturing within the trocar site is feasible and beneficial, especially for the most neurologically impaired pediatric cases. Technical modification, changing the order of the process, and suturing technique in the minimal space, made it easier to perform the procedures inside the minimal trocar hole.
