1. A surgical method for performing an anastomosis, comprising the steps of:

  • disposing a laparoscopic trocar sleeve in a patient'"'"'s abdominal wall;

    inserting a distal end of a laparoscopic instrument into an abdominal cavity of the patient through said trocar sleeve;

    manipulating said instrument from outside the patient to loop a purse-string-type suture through a free end of a first severed intestinal segment of the patient;

    moving a flexible anastomosis-forming device through the patient'"'"'s rectum so that an end cap at a distal end of said anastomosis device protrudes from a free end of a second severed intestinal segment of the patient;

    shifting said anastomosis-forming device further through the patient'"'"'s rectum so that said end cap is inserted into said first severed intestinal segment through the free end thereof;

    during said step of shifting, holding said first severed intestinal segment with a laparoscopic tool from outside the patient to facilitate insertion of said end cap into said first severed intestinal segment;

    upon insertion of said end cap into said first severed intestinal segment, drawing said purse-string-type suture via a laparoscopic member to close the free end of said first severed intestinal segment about said end cap; and

    operating said anastomosis-forming device from outside the patient to connect said first and said second severed intestinal segment to one another in an anastomosis.
