Jejunum: jejunocecostomy

ISSN 2398-2977


Introduction

  • If the majority of the ileum requires resection it is recommended to perform a jejunocecal anastomosis, thereby bypassing the remnants of the ileum. If the oral most aspect of the ileum (1-25 cm) are involved, a jejunoileostomy can be performed.
  • Reasons include: the relative inaccessibility of the mid to distal ileum due to its intra-abdominal position during surgery.

Uses

  • To re-establish the continuity of the gastrointestinal tract after ileal resection.

Advantages

  • Better accessibility.

Disadvantages

  • Technically demanding.
  • Defects in mesentery must be closed to prevent potential mesenteric strangulation.
  • Risks of abdominal contamination.
  • Post-operative cecal dysfunction, kinking of jejunum, and/or colic.
  • Technically demanding.
  • Easier to perform if stapling instruments are used - increased cost.

Technical problems

  • Accessibility of distal ileal stump for oversewing.
  • Abdominal contamination
  • Mesenteric closure.
  • Tissue too thick for staple usage; tissue inflamed of friable, so suture holding capabilities are decreased.

Alternative techniques

  • End-to-end anastomosis of ileum - jejunoileostomy.
  • Incomplete jejunocecal bypass - side-to-side anastomosis and leave normal ileal pathway open, eg ileal muscular hypertrophy Ileum: muscular hypertrophy, etc.
  • Equipment/technique: hand suturing or stapling devices.

Time required

Preparation

Procedure

  • Hand sewn end-to-side or side-to-side anastomosis including mesenteric repair: 30-60 min depending upon competence.
  • Side-to-side anastomosis using stapling device: 30-45 min.

Decision taking

Criteria for choosing test

  • Same as ileal surgical lesions and criteria for surgical resection.
  • Most commonly small intestinal strangulating lesions that involve the ileum:
    • Pedunculated lipoma.
    • Mesenteric rent.
    • Epiploic foramen entrapment.
    • Inguinal/scrotal hernia.
    • Small intestinal volvulus.

Risk assessment

  • Breakdown of anastomosis.
  • Viability of ileal stump left in place.
  • SIRS.
  • Cecal function.
  • Acute abdominal diseases risks for anesthesia.
