ABSTRACT Analogous to organ injury scales developed for trauma, a scoring system is needed for acute care surgery. The purpose of this study was to develop a disease severity score (DSS) for acute appendicitis, the most common surgical emergency.
A panel of acute care surgery experts reviewed the literature and developed a DSS for acute appendicitis as follows: grade 1, inflamed; Grade 2, gangrenous; Grade 3, perforated with localized free fluid; Grade 4, perforated with a regional abscess; and Grade 5, perforated with diffuse peritonitis. We applied the DSS to 1,000 consecutive patients undergoing appendectomy from 1999 to 2009 and examined its association with outcomes (mortality, length of hospital stay, incidence of in-hospital, and postdischarge complications). Of the 1,000 patients, 82 were excluded owing to negative or interval appendectomy or advanced end-stage renal disease.
Among 918 eligible patients, the DSS distribution was Grade 1 at 62.4%, Grade 2 at 13.0%, Grade 3 at 18.7%, Grade 4 at 4.4%, and Grade 5 at 1.5%. Statistical analyses indicated a stepwise risk increase in adverse outcomes with higher DSS grades (c statistics ≥ 0.75 for all outcomes). Covariates (age, sex, and type of surgical access) did not add to the predictive power of DSS.
Based on this single-institution study, the proposed appendicitis DSS seems to be a useful tool. This DSS can inform future, national efforts, which can build on the knowledge provided by the present investigation. This DSS may be useful for comparing therapeutic modalities, planning resource use, improving programs, and adjusting reimbursement

    ABSTRACT: A transumbilical laparoscopic-assisted single-channel, single-port procedure was introduced during laparoscopic interval appendectomy for mass-forming appendicitis in children. The aim of this study was to evaluate the results of the original laparoscopic interval appendectomy. This study analyzed 31 children who underwent laparoscopic interval appendectomy using a single-channel, single-port procedure. The appendectomy was usually planned 8–12 weeks following initial conservative treatment. The procedure was a single-channel surgery using a 12-mm single port. Both a 5-mm telescope and grasper were inserted simultaneously into the single channel. The grasper held the appendix, and an extracorporeal appendectomy was performed. Appendectomy was planned for 29 patients, as 2 patients deviated from the protocol. The procedure was successful in 21 patients (72.4%). An accessory port was necessary in eight patients, two of whom successfully underwent laparoscopic surgery; the remaining six were converted to open appendectomy. The average length of surgery was 43 min in the single-channel, single-port procedure. No postoperative complications occurred in any patient. The single-channel, single-port procedure was successfully performed in over 70% of the patients. This preliminary retrospective analysis indicates that the procedure is safe and potentially beneficial in children with mass-forming appendicitis who require laparoscopic interval appendectomy.

    ABSTRACT: Appendicectomy (AE), the most frequent emergency surgical procedure, can be performed as a transvaginal hybrid natural orifice translumenal endoscopic surgery (NOTES) technique (TVAE). The question of feasibility also arises in cases of advanced inflammation with perforation.

    ABSTRACT: Studies evaluating mortality in patients with acute appendicitis focus on the outcomes of appendicectomy alone. We hypothesize this may not be representative of what happens in clinical practice as a small proportion of patients with acute appendicitis undergo procedures other than appendicectomy, for example, caecectomy or right hemicolectomy. To clarify the issue, the authors evaluated Australian adult patients who died with a primary diagnosis of acute appendicitis regardless of whether they underwent an operation or the type of operation performed.
