[APPENDECTOMY. PERSONAL TECHNIC].

The diagnosis of uncomplicated acute appendicitis is often straightforward, allowing timely appendicectomy without the need for expensive tests or imaging. Repeated clinical examination by an experienced surgeon has traditionally been the key to making the diagnosis in both straightforward and difficult cases. Nonetheless, all surgeons will remove some normal appendices. Sometimes it can be particularly difficult to make the diagnosis, especially in the child under 5 years of age, in teenage girls, in young women and in the elderly. When difficult to make, the diagnosis may be significantly delayed and since the pathology is progressive, the patient may suffer potentially avoidable complications. This paper looks at two potential roles for imaging. Firstly, can imaging, applied selectively, help make the difficult diagnosis less difficult and so reduce delays and morbidity? Secondly, could imaging all patients with suspected appendicitis reduce the number of normal appendices removed from children who seem to have all the signs and symptoms of straightforward uncomplicated acute appendicitis but who actually have presumed self-resolving non-appendiceal pathology? The answer to these questions may depend on three factors that are not entirely independent: a surgical unit's current audited negative appendicectomy rate, population base/case mix and the expertise of the examining surgeon. Individual surgeons and some surgical units, by policy, use modern imaging techniques with quite different frequencies that may be appropriate depending on these three factors. This article argues that a careful history and repeated clinical examination is the key to making the diagnosis, with imaging, primarily ultrasonography, being used in patients with a palpable mass or in those having had 48 h of hospital observation without progress. In Europe, imaging has played a limited role in the investigation of the child with suspected appendicitis with the diagnosis relying on repeated examination by an experienced clinician. Ongoing changes in surgical training in the UK may affect the acquisition of clinical expertise that is crucial to this clinical management. High-quality surgical training and surgical audit are needed to monitor the delivery of care and to ensure that the care pathway being used is appropriate for the local resources and population.

Laparoscopic appendectomy is a favorable alternative for complicated appendicitis in children.

Laparoscopic appendectomy in children is a generally accepted procedure for the treatment of non-complicated acute appendicitis. Nevertheless, the role of laparoscopy in complicated appendicitis is more controversial. The objective of this study was to examine the safety, efficacy and complications of laparoscopy in children with complicated appendicitis. This is a retrospective review of the children who underwent laparoscopic appendectomy for complicated appendicitis at King Khalid University Hospital, Riyadh, Saudi Arabia between January 1998 and March 2006. Complicated appendicitis includes perforated appendicitis, gangrenous appendicitis and appendicular masses found intra-operatively. Data collected include demographic, duration of symptoms, operative time, analgesia, complications, length of hospitalization and histopathology. Laparoscopic appendectomy was done by three trocar technique in all cases. During the study period, 59 children aged 3-12 years underwent laparoscopic appendectomy for complicated appendicitis. There were 34 patients with perforated appendicitis, 12 patients with gangrenous appendicitis and 13 patients with appendicular mass. The average operating time was 62 min. The average length of hospitalization was 5 days. The post-operative narcotic analgesic requirement was minimal. Laparoscopy was converted to open surgery in two patients (3.38%). These two cases were excluded from further analysis. Four out of 57 patients (7.01%) had post-operative complications. Three patients (5.26%) developed wound infection. One patient (1.75%) developed haematoma at umbilical port site. There was no post-operative intra-abdominal collection. Laparoscopic appendectomy is a safe alternative for the treatment of complicated appendicitis. It does not increase the incidence of complications even with complicated appendicitis. Contrary to the previous studies, we did not have increased incidence of intra-abdominal collection in this review. However, prospective randomized controlled trials are needed to verify these findings.
