ABSTRACT
From 1-2002 to 7-2004, 401 cases of appendicitis were operated on laparoscopically at Hoan my
Danang general hospital. Of which there were 332 acute, 19 gangrenous appendicitis, 16 abscesses, 27
generalized and 7 localized peritonitis. In 28 patients, appendectomy was performed along with
enucleated and endocoagulated ovarian cysts or oophorectomy for ovarian cyst torsion (3 cases),
resection with electrodessication of pelvic endometriosis cysts (3 cases), resection of tube for abscesses
(4 cases) or ectopic prgnancy (1 case), resection of epiploic appendicitis or part of great omentum
necrosis (2 cases), and 14 adhesiolyses. There were no port infections. We performed only one (0.25%)
conversion to open exploration and experienced two (0.5%) complications in which one was peritonitis
needed reoperation and one was Douglas' pouch abscess needed endoscopic drainage but both were
safely discharged. Though the operative time is longer for laparoscopic cases, but patients had less pain,
early resuming of bowel movements, short hospital stay, sooner discharge and return to full activity in a
short time. It is preferred in obese patients who would require a large incision for an open approach and
in patients who are very concerned about cosmesis because minilaparoscopic approaches are based on
its low invasiveness and small surgical incisions.
Mortality was non-existent. Reoperation rate was 0.5%.
Laparoscopic appendectomy is now a safe and efficacious technique for all forms of appendicitis.
