How to accommodate discrepancies in luminal size when performing a resection-anastomosis

  • Increase spacing between suture bites on the larger diameter lumen compared to the smaller one. This is effective to treat small diameter discrepancies.
  • Increase the luminal diameter of the smaller lumen by cutting the smaller lumen at a more acute angle than the larger lumen (always making the antimesenteric border shorter than the mesenteric border). This is effective to treat small diameter discrepancies.
  • A small wedge of tissue can also be removed from the antimesenteric portion of the smaller diameter lumen creating a more oval opening that fits the larger diameter lumen. This can be used for moderate to large lumen discrepancies but in my experience is rarely necessary.
  • Apposing the lumens evenly and closing the extra lumen as a cul-de-sac is not recommended.
