Contraindications

Appendicitis complicated by bowel obstruction with abdominal distension (mesoceliac appendicitis).

Technical Notes

1. Leave a povidone iodine gauge in the umbilicus until the patient enters the operating room. 2. Place a Foley catheter before the procedure. 3. Preoperative resuscitation should be done if there are signs of peritonitis. 4. In case of suspected perforation, antibiotics should be administered before general anesthesia is induced.

1. Manipulate the fragile appendix with care. In this case, manipulation using the mesoappendix is re­commended. 2. In cases of localized abscess, care should be taken not to burst the abscess. Pus should be aspirated using a large needle inserted through the abdominal wall under laparoscopic guidance. 3. A preperforative or perforated appendix must be removed from the abdomen in an specimen retrieval bag.

35.10 Laparoscopic Appendectomy

Procedure Variations

1. Extra-abdominal (laparoscopic-assisted), singleport method (see Chap. 36). 2. Mixed technique (mesoappendix hemostasis performed intra-abdominally and the appendix is ligated extra-abdominally), three-port method. 3. Intra-abdominal techniques with: a. Endoscopic stapler. b. Intra-/extracorporeal suturing.
