[Resection anastomosis of the small intestine by celioscopy in swine. Comparative experimental study between manual and mechanical anastomosis].
Laparoscopic intestinal anastomosis is not very reliable and needs to be evaluate in an experimental model in animals before being performed in man. The purpose of this study was to evaluate the feasibility, efficacy and safety of manual anastomosis comparatively to the standard stapling suture. Twenty female pigs weighing 20 +/- 5 kg. were used for this study. A 5 cm ileal segment resection was performed under laparoscopy. The animals were assigned to 2 groups. Group I: 10 animals underwent end-to-end hand-swen anastomosis with Polyglactin 910, dec 1.5. Group II: 10 animals underwent side-to-side anastomosis using the Endo stapler. Operating time and anastomosis time were compared using the Mann-Whitney test for statistical analysis. On the 15th postoperative day, the animals were sacrificed and the anastomoses were evaluated. There was no operating death in the 2 groups. The operative time was significantly longer in group I than in group II (p < 0.01), with 180 +/- 40 min vs 49 +/- 25 min respectively. This difference was due to the anastomosis time of 130 +/- 40 min vs 16 +/- 6 min respectively (p < 0.01). There was 1 postoperative death related to fistula and peritonitis in group I and none in group II. The post-operative follow-ing showed 5 anastomotic leakages (4 in group I and 1 in group II) and 2 relative stenoses in group I. This study shows the simplicity and rapidity of performing stapling intestinal anastomosis under laparoscopy. Hand-sewn anastomosis is technically more difficult to perform under laparoscopy and requires a greater experience.
