KUMACONE-II - AN ADAPTER TO AID IN THE PLACEMENT OF A PURSE-STRING SUTURE IN VERY-LOW ANTERIOR RECTAL RESECTION

We have designed an adapter called the ''Kumacone II'', being a bottle -shaped rubber device which greatly aids in placing a purse-string sut ure, even at the lowest level near the anorectal junction of the rectu m. When this adapter is used, performing the anastomosis is much less time-consuming and not as much training is needed as for low anterior resection using conventional manual suturing. In a clinical study, the incidence of leakage and incontinence was nil in five out of five pat ients.
