Abdomen: laparoscopy

pequis

Introduction

  • An endoscopic surgical technique similar to arthroscopy Joint: arthroscopy - overview that involves the use of a rigid fiberoptic telescope coupled to a light source for viewing, and specialized instruments for surgical manipulation based on the principle of triangulation.
  • Indicated for some types of abdominal surgery and for diagnostic purposes (following full clinical examination, haematology, fluid/aspirate analysis and ultrasonography), eg:
    • Recurrent or acute colic.
    • Persistent weight loss.
    • Peritonitis.
    • Urogenital disease.
    • Rectal injuries.

Uses

Diagnostic

Surgical

  • Cryptorchidectomy:
  • Ovariectomy:
    • Standing flank or ventral abdominal Ovary: ovariectomy - laparotomy approach.
    • Each ovary is routinely removed from the ipsilateral side, though a report of bilateral ovariectomy via left sided approach has been published.
    • The ovarian pedicle may be infiltrated with local anesthetic or a caudal epidural Anesthesia: epidural performed in the standing patient.
    • The ovary is usually removed after dissection of the ovarian pedicle and application of 1 or 2 Endoloop® sutures or via coagulation.
    • Alternatives include laser transection or use of a laparoscopic stapling device.
  • Inguinal hernia repair:
    • General anesthesia and ventral abdominal laparoscopy or standing flank with sedation.
    • Repair with automated stapling devices for mesh implantation to close vaginal ring, polypropylene mesh stapled in place sub-peritoneally, barbed suture, peritoneal flap or cyanoacrylate.
  • Ruptured bladder:
  • Reproductive system:

Advantages

  • Good visualization of the abdominal or thoracic cavity under exploration.
  • Unique visualization of dorsal abdominal organs and conditions, eg duodenal adhesions.
  • Short post-operative convalescent period due to minimal surgical trauma.
  • Fewer complications than with laparotomy.
  • Standing laparoscopy does not require general anesthesia.

Disadvantages

  • Amount and expense of instrumentation.
  • Requirement for new skills.
  • Some procedures technically difficult or not possible, eg intestinal biopsy.
  • Inaccessibility of some abdominal organs.
  • Increased number of false negatives in diagnostic procedures compared with laparotomy.

Prognosis

  • For elective procedures (ovariectomy, cryptorchidectomy, hernia repair, nephrosplenic space closure) prognosis is good.
  • For reasons of disease or biopsy, the prognosis is dependent upon underlying condition or results of the biopsy.
