Improved design knot pusher for laparoscopic extracorporeal suturing

A gasless laparoscopic technique of wide excision for gastric gastrointestinal stromal tumor versus open method

Background

Traditional open surgery for gastrointestinal stromal tumors (GIST) requires a long incision. Moreover, the gas-filling laparoscopic technique used in GIST surgery still has its limitations. Therefore, we developed a gasless laparoscopic (GL) surgery for GIST and compared it with traditional open surgery.

Methods

Between October 2007 and September 2009, 62 GIST patients in the National Taiwan University Hospital received wide excisions. Of these 62 patients, 30 underwent the new procedure (GL group) and 32 had open surgery (OS group). Preoperative and postoperative clinicopathologic characteristics were compared between the groups.

Results

There were no significant differences in preoperative characteristics or blood loss. However, the days to first flatus, postoperative hospital stay, wound length, white blood cell count at postoperative day one, and peak daily body temperature were all significantly improved in the GL group. Usage of postoperative analgesia on postoperative days one to five was also significantly lower in the GL group.

Conclusions

Wide-excision laparoscopy for gastric GIST can be performed more safely, more effectively, and with faster postoperative recovery using the gasless technique as compared with the open method. We, therefore, recommend this new surgical technique, which hybridizes the advantages of both the traditional open method and pure laparoscopic surgery.

The Minailo knot: a time-saving and cost-saving technique

Endoscopic knot tying during minimally invasive surgery can be complicated, time consuming, and associated with a protracted learning curve. The Minailo knot seems to be a reasonable option because the technique does not require any specialized instrumentation or skill to perform. In particular, vaginal closure is obtained with the placement of a single intra-corporeal knot. Our initial and successful experience with this knot-tying technique during robotic hysterectomy for treatment of gynecologic disease suggests that the method is safe and feasible.
