Evaluation of the mechanical strength and patency of functional end-to-end anastomoses

Abstract

The bursting pressure of the mechanical staple line using the EndoGIA 60 stapler was the strongest. Functional end-to-end anastomosis was stronger when created with buttress of an anastomotic crotch, and larger circumferences were created with the wide technique.

The importance of precompression time for secure stapling with a linear stapler

“…The optimal formation rate in the top aspect was lower than that in the root completed without proper devices [11,12]. Although the surgical techniques to ensure a satisfactory blood supply and no tension to the anastomotic site are essential, correct usage of the proper devices also is important to prevent anastomotic failure [6][7][8][9][10]. However, only a few studies have described the proper use of linear suturing devices.…”

“…Several reports have described how to improve outcomes after mechanical anastomosis [6][7][8][9][10]. However, to our knowledge, no report describing the cause of staple malformation (staples not forming the ''B'' shape) exists.…”

Reinforcement Does Not Necessarily Reduce the Rate of Staple Line Leaks After Sleeve Gastrectomy. A Review of the Literature and Clinical Experiences

“…Because ischemic leaks are known to occur 5-7 days postoperatively, when wound healing is between the inflammatory and fibrotic phases, the most common causes of the vast majority of leaks, which occur within 48 h, are mechanical [26]. This provides a rationale for buttressing materials, which do not impart a decreased risk of leakage due to ischemia, but do decrease the risk of mechanical failure [50]. Most [6][7], but not all [31], studies have found that buttressing materials increase burst pressure.…”

Comparison of Postoperative Motility in Hand-Sewn End-to-End Anastomosis and Functional End-to-End Anastomosis: An Experimental Study in Conscious Dogs

“…Although hand-sewn end-to-end anastomosis has been representative of intestinal anastomosis, the role of functional end-to-end anastomosis [1] using an automatic linear stapler is rapidly being established. Functional end-to-end anastomosis has been shown to be safe and has become quite popular in clinical settings [2,3].…”
