RT Journal A1 Walfish J, Frankel A T1 CHronic pseudo-obstruction secondary to side-to-side intestinal anastomosis JF Archives of Surgery JO Archives of Surgery YR 1979 FD September 1 VO 114 IS 9 SP 1075 OP 1078 DO 10.1001/archsurg.1979.01370330097019 UL http://dx.doi.org/10.1001/archsurg.1979.01370330097019 AB • An unusual late complication of side-to-side intestinal anastomosis, chronic small-bowel obstruction with massive proximal ileal dilation despite a widely patent anastomosis, occurred in a patient. The classic blind loop syndrome was not present. Several potential mechanisms are suggested, including regional absence of normal peristalsis on a mechanical basis and bacterial overgrowth. This report adds support to the concept that side-to-side intestinal anastomosis should be avoided whenever possible.(Arch Surg 114:1075-1078, 1979)
