Left-sided appendicitis:Review of 95 published cases and a case report

AIM:To give an overview of the literature on left-sided acute appendicitis (LSAA) associated with situs inversus totalis (SIT) and midgut malrotation (MM).METHODS:We present a new case of LSAA with SIT and a literature review of studies published in the English language on LSAA,accessed via PubMed and Google Scholar databases.RESULTS:Ninety-five published cases of LSAA were evaluated and a 25-year-old female,who presented to our clinic with left lower abdominal pain caused by LSAA,is reported.In the reviewed literature,fiftyseven patients were male and 38 were female with an age range of 8 to 82 years and a median age of 29.1 ± 15.9 years.Sixty-six patients had SIT,23 had MM,three had cecal malrotation,and two had a previously unnoted congenital abnormality.Fifty-nine patients had presentedto the hospital with left lower,14 with right lower and seven with bilateral lower quadrant pain,and seven subjects complained of left upper quadrant pain.The diagnosis was established preoperatively in 49 patients,intraoperatively in 19,and during the postoperative period in five;14 patients were aware of having this anomaly.The data of eight patients were not unavailable.Eleven patients underwent laparoscopic appendectomy,which was combined with cholecystectomy in two cases.Histopathological examination of the appendix specimens revealed adenocarcinoma in only two of 95 patients.CONCLUSION:The diagnosis of left lower quadrant pain is based on well-established clinical symptoms,physical examination and physician's experience.

Unusual histopathological findings in appendectomy specimens:A retrospective analysis and literature review

AIM: To document unusual findings in appendectomy specimens. METHODS: The clinicopathological data of 5262 patients who underwent appendectomies for presumed acute appendicitis from January 2006 to October 2010 were reviewed retrospectively. Appendectomies performed as incidental procedures during some other operation were excluded. We focused on 54 patients who had unusual findings in their appendectomy specimens. We conducted a literature review via the PubMed and Google Scholar databases of English language studies published between 2000 and 2010 on unusual findings in appendectomy specimens. RESULTS: Unusual findings were determined in 54 (1%) cases by histopathology. Thirty were male and 24 were female with ages ranging from 15 to 84 years (median, 32.2 ± 15.1 years). Final pathology revealed 37 cases of enterobiasis, five cases of carcinoids, four mucinous cystadenomas, two eosinophilic infiltrations, two mucoceles, two tuberculosis, one goblet-cell carcinoid, and one neurogenic hyperplasia. While 52 patients underwent a standard appendectomy, two patients who were diagnosed with tuberculous appendicitis underwent a right hemicolectomy. All tumors were located at the distal part of the appendix with a mean diameter of 6.8 mm (range, 4-10 mm). All patients with tumors were alive and disease-free during a mean follow-up of 17.8 mo. A review of 1366 cases reported in the English literature is also discussed. CONCLUSION: Although unusual pathological findings are seldom seen during an appendectomy, all appendectomy specimens should be sent for routine histopathological examination.
