Background: Although several procedures for mechanical anastomosis have recently been reported, intracorporeal manually hand-sewn anastomosis for totally laparoscopic pylorus-preserving gastrectomy (TLPPG) is considered technically difficult. Here, we report a new technique for laparoscopic reconstruction using hand-sewn sutures.
Methods: Together with a proper lymphadenectomy, the stomach was detached and resected using separate two-layer incisions, similar to the original laparotomy method. An approximately 5-cm antral cuff was left in place. The essential concept of this new method was to align the anastomotic site by rotating each clamped gastric stump. This allowed us to perform a secure, hand-sewn, two-layer anastomosis successfully. The short-term surgical outcome after TLPPG was retrospectively compared with that for patients who underwent a conventional laparoscopy-assisted procedure (LAPPG).
Results: Of the 20 consecutive patients who underwent pylorus-preserving gastrectomy in our department between 2014 and 2021, the first 8 patients and the subsequent 12 patients underwent LAPPG and TLPPG, respectively. The operation time was significantly longer in the TLPPG group (median, 302 vs. 269 min). The morbidity was comparable (8.3% in TLPPG vs. 12.5% in LAPPG). Postoperative delayed gastric emptying was only observed in one patient in the LAPPG group. TLPPG reduced the cost of the operation by reducing the number of linear stapler cartridges required.
Conclusion: A purely hand-sewn gastrogastrostomy is safe, feasible, and cost-effective, and it omits the need for a mini-laparotomy in the upper abdomen.
