Abstract
In combination with the biofragmentable Valtrac ring a newly developed purse-string suture clamp offers the possibility of performing intraperitoneal anastomoses of the small and large bowel without the need for stapling devices. During this experimental study endto-end anastomoses of the descending colon were constructed in five pigs. One animal was re-examined on day 1 after the operation and the others were all sacrificed on day 21 after. None of the animals showed any signs of an anastomotic leakage. Little scar tissue was seen macroscopically or histologically in the anastomotic region of the animals sacrificed 3 weeks after the operation. The operative technique presented in this paper might render the so-called assisted laparoscopic procedures for the right hemicolon unnecessary in the future.
Zusammenfassung
Eine neu entwickelte laparoskopische Tabaksbeutelnahtklemme bietet in Kombination mit dem biofragmentierbaren Valtrac®-Ring die Möglichkeit, Anastomosen im Dünn- und Dickdarm intrakorporal ohne Stapler zu erstellen. Im Rahmen der hier vorgestellten tierexperimentellen Studie wurde bei 5 Schweinen eine End-zu-End-Anastomose im Colon descendens gebildet. Die Nachuntersuchung erfolgte bei 4 Tieren nach 21 Tagen und bei einem Tier am 1. postoperativen Tag. Eine Anastomoseninsuffizienz war in keinem Fall festzustellen. Die Anastomosen der Tiere, die 3 Wochen postoperativ nachuntersucht wurden, wiesen sowohl makroskopisch als auch histologisch nur geringe Narbenbildung auf. Die hier vorgestellte Anastomosentechnik könnte in Zukunft eine Alternative zu den assistiert laparoskopischen Eingriffen am rechten Kolon darstellen.
