This protocol deals with right hemicolectomy for cancer grossing.

It is done for cancers in the cecum, right colon, and appendix. Right hemicolectomies are also commonly done for Crohn's disease; this is dealt with in a separate article.

Introduction

It is very common.

Protocol

Specimen:

  • Right hemicolectomy.

Dimensions:

  • Length large bowel: ___ cm.
  • Length small bowel: ___ cm.
  • Circumference - proximal end: ___ cm.
  • Circumference - distal end: ___ cm.
  • Appendix: length ___ cm, diameter ___ cm.

Appearance - external:

  • Serosal aspect of bowel: [shiny].
  • Perforation: [present/not present].

Inking:

  • Circumferential margin: [black]. §
  • Serosal puckering: [blue].

Tumour characteristics:

  • Dimensions (along axis, circumferential, depth): ___ x ___ x ___ cm.
  • Distance to nearest mucosal margin: ___ cm, [distal] margin.
  • Distance to circumferential margin: ___ cm.
  • Circumferential location: [anterior/left/right/posterior/circumferential].

Representative sections are submitted as follows:

  • Proximal margin. ‡
  • Distal margin. ‡
  • Tumour - deepest invasion.
  • Additional sections of tumour (1 section/cm).
  • All polyps (if less than 10).
  • Normal appearing mucosa.
  • Lymph nodes. †

Protocol notes

  • ‡ Usually submitted completely and en face; if the margin is close (<2 cm) on edge is typically preferred.
  • † Recommended minimum number of lymph nodes is 12.[1]
  • § The retroperitoneal margin in right hemicolectomies should be treated like the radial margin in total mesorectal excisions; it should be inked.[2] Involvement is a poor prognosticator.[3]
