RESUMO
OBJECTIVES: To determine the prevalence of appendiceal histopathology in patients with confirmed endometriosis following minimally invasive surgery (MIS) for endometriosis. To determine whether pre-operative symptoms, age, intra-operative appendiceal appearance, or endometrioma laterality were associated with appendix histopathology in patients with suspected endometriosis. METHODS: One hundred thirty-five patients ages 16-52 with suspected endometriosis undergoing MIS for endometriosis with concomitant appendectomy at two metropolitan academic hospitals from January 1, 2012 to June 30, 2017 were included in this retrospective chart-review study. Medical records were reviewed for pre-operative symptoms, age, intraoperative appendix appearance, appendix histopathology, histopathologically-confirmed endometriosis, and endometriomas. RESULTS: In patients with confirmed endometriosis, the prevalence of all appendiceal histopathology was 25%, which included appendiceal endometriosis (18%), appendiceal tumors (2%), and inflammation (5%). Dyspareunia was the only pre-operative symptom significantly associated with appendiceal histopathology (p = 0.04). The presence of a right endometrioma was associated with appendiceal histopathology (p = 0.009). Additionally, appendiceal histopathology was not significantly associated with age nor intra-operative appendiceal characteristics. CONCLUSION: This manuscript adds to the limited pool of studies regarding appendiceal histopathology and appendiceal tumors in patients with suspected and confirmed endometriosis. On the basis of the high rate of histopathological appendices found in this population; the lack of association with possible diagnostic factors such as age, most pre-operative symptoms, and intra-operative appendiceal characteristics; and the relatively low risks of concomitant appendectomy, we suggest that surgeons consider concomitant appendectomies at the time of MIS for endometriosis.

OBJECTIVE. With heightened interest in nonoperative antibiotic management of uncomplicated appendicitis, appendicoliths become a more relevant issue, and because of higher failure rates their presence may be considered a contraindication. The purpose of this study was to investigate the prevalence of appendicoliths at CT in adults with suspected appendicitis. MATERIALS AND METHODS. Among adults undergoing MDCT for suspected appendicitis, 248 patients (134 women, 114 men; mean age, 35.2 years) consecutively registered over a 3-year period constituted a cohort with surgically proven appendicitis. A cohort of 248 patients (175 women, 73 men; mean age, 37.7 years) without appendicitis consecutively registered over a 1-year period served as control subjects. CT examinations were reviewed for the presence, size, and attenuation of appendicoliths and whether the appendicoliths were obstructing. In the cohort with appendicitis, degree of inflammation (3-point scale) and likelihood for perforation (5-point scale) were scored. RESULTS. The prevalence of appendicoliths at CT was 38.7% (96/248) among patients with appendicitis and 4.4% (11/248) among control subjects (p < .001). Among the 96 patients with appendicitis who had visible appendicoliths, mean width, length, and maximum attenuation of the dominant appendicolith were 6.0 mm, 8.2 mm, and 313 HU, respectively. In 70.8% (68/96) of patients appendicoliths were obstructing, and 32.3% (31/96) of patients had more than one appendicolith. Inflammation (1.75 vs 1.43) and likelihood of perforation (2.07 vs 1.51) (p < .05) scores were higher among patients with appendicitis who had appendicoliths. Extraluminal appendicoliths were seen in five cases of perforated appendicitis. CONCLUSION. Appendicoliths were identified at CT in nearly 40% of adults with proven appendicitis, compared with slightly more than 4% of those without appendicitis, and were associated with increased inflammation and risk of perforation.

INTRODUCTION: Appendicitis is the most common surgical emergency. Most commonly it is a result of luminal occlusion that leads to ischaemia and eventually to perforation with resultant localised or diffuse peritonitis. Unusual causes have been documented including viral infections, parasites, tuberculosis and neoplasms. These conditions are important to recognise, as they may need additional specific management. This study endeavours to identify the incidence and type of unusual histopathology of appendicitis. METHOD: A retrospective review of histopathological reports of appendix specimens obtained during appendectomies done between January 2012 and December 2014 in the three academic hospitals of Johannesburg - Chris Hani Baragwanath Academic Hospital (CHBAH), Charlotte Maxeke Johannesburg Academic Hospital (CMJAH), and Helen Joseph Hospital (HJH). All specimens were examined by pathologists of the National Health Laboratory Services (NHLS). RESULTS: A total of 2 408 histopathology results were obtained from the NHLS. 164 specimens were excluded because they were part of colonic resection for unrelated conditions. Of the 2 244 specimens included, 8.1% were normal, 52.7% showed acute appendicitis and 30.1% showed complicated appendicitis. Unusual pathology comprised 5.3% (119/2 244). The median age of all patients was 25.6 years (0-88yrs) and the gender distribution was 61.9% males and 38.1% females. The most common unusual causes were parasites (37%), mainly schistosomiasis (24.3%), followed by neoplasm (20%) and fibrous obliteration (14.2%). CONCLUSION: All appendectomy specimens must be submitted to the pathologist for histological diagnosis. It is important that the result be checked before the patient is discharged as further specific treatment may be indicated.

STUDY OBJECTIVE: To evaluate appendiceal endometriosis (AE) prevalence and risk factors in endometriotic patients submitted to surgery. DESIGN: A retrospective cohort study. SETTING: A tertiary level referral center, university hospital. PATIENTS: One thousand nine hundred thirty-five consecutive patients who underwent surgical removal for symptomatic endometriosis. INTERVENTIONS: Electronic medical records of patients submitted to surgery over a 12-year period were reviewed. We assessed any correlation between demographic, clinical, and surgical variables and AE. In our center, appendectomy was performed using a selective approach. Appendix removal was performed in case of gross abnormalities of the organ, such as enlargement, dilation, tortuosity, or discoloration of the organ or the presence of suspected endometriotic implants. MEASUREMENTS AND MAIN RESULTS: AE prevalence was 2.6% (50/1935), with only 1 false-positive case at gross intraoperative evaluation. In multivariate analysis using a stepwise logistic regression model, independent risk factors for AE were adenomyosis (adjusted odds ratio [aOR]â¯=â¯2.48; 95% confidence interval [CI], 1.32-4.68), right endometrioma (aORâ¯=â¯8.03; 95% CI, 4.08-15.80), right endometrioma ≥5 cm (aORâ¯=â¯13.90; 95% CI, 6.63-29.15), bladder endometriosis (aORâ¯=â¯2.05; 95% CI, 1.05-3.99), deep posterior pelvic endometriosis (aORâ¯=â¯5.79; 95% CI, 2.82-11.90), left deep lateral pelvic endometriosis (aORâ¯=â¯2.11; 95% CI, 1.10-4.02), and ileocecal involvement (aORâ¯=â¯12.51; 95% CI, 2.07-75.75). CONCLUSION: Among patients with endometriosis submitted to surgery, AE was observed in 2.6%, and it was associated with adenomyosis, large right endometrioma, bladder endometriosis, deep posterior pelvic endometriosis, left deep lateral pelvic endometriosis, and ileocecal involvement.

OBJECTIVE: To determine whether deep-infiltrating endometriosis (DE) carries an increased risk of appendiceal endometriosis (AppE) as compared with superficial endometriosis or no endometriosis. METHODS: In a retrospective study, data were obtained by chart review of an internal database for women who underwent coincidental appendectomy during benign gynecologic surgery between July 2009 and February 2014 at a tertiary referral center in the USA. Univariate, bivariate, and regression analyses were performed. The primary exposure was surgically documented endometriosis (DE, superficial, or no endometriosis). The primary outcome was AppE. RESULTS: Endometriosis was diagnosed for 151 (38.2%) of 395 women; 82 (54.3%) had DE. The prevalence of AppE was 13.2% (52/395) overall; 8 (11.6%) of 69 women with superficial endometriosis and 32 (39.0%) of 82 with DE were affected. Frequency of AppE was increased among women with DE, abnormal appendix appearance, and surgical indication (all P<0.001). Women with DE had a 5.9-fold (95% confidence interval [CI] 2.9-11.9) higher risk of AppE compared with women without endometriosis, controlling for appendiceal appearance and surgical indication, and a 2.7-fold (95% CI 1.2-6.2) higher risk of AppE compared with those with superficial endometriosis. CONCLUSION: Women with DE have increased risk of AppE. Coincidental appendectomy should form part of complete endometriosis excision for these patients.

INTRODUCTION: Neurogenic appendicopathy is not a very well-known disease. OBJECTIVE: To analyze the experience in the management of neurogenic appendicopathy in a tertiary hospital, assessing its clinical presentation, histological staging, the treatment carried out and its clinical evolution. METHOD: The study population included patients with histopathological criteria for neurogenic appendicopathy who did not present with MEN 2B syndrome, neurofibromatosis type I or Cowden syndrome. An analysis was carried out of tissue samples taken from a simple appendectomy after a diagnosis of neurogenic appendicopathy between 2000 and 2013, inclusive. The histopathological criteria were neurogenic hyperplasia with S-100 protein positivity and neuron-specific enolase in the immunohistochemical analysis. RESULTS: Of the 4,969 samples from the appendectomies analyzed, 0.16% (n = 8) met histopathological criteria of neurogenic appendicopathy. The age at presentation was 27.8 ± 12 years. Four patients were male and four were female. All patients started with abdominal pain in the right iliac fossa (RIF), and were operated on due to a diagnosis of acute appendix, with a simple appendectomy being performed. In four cases, another associated disease accounted for the pain in the RIF. With regard to histopathological type, submucosal neurogenic hyperplasia was present in five patients and fibrous obliteration in three patients. No statistically significant differences were found between the histological types. After surgery, during a mean follow up of 73.2 ± 28 months (15-105), all the patients remained asymptomatic. CONCLUSION: Neurogenic appendicopathy is an uncommon entity that can evolve as abdominal pain which is similar to acute appendix. Simple appendectomy is curative.

Cecal infarction is an uncommon lesion in calves that results in localized peritonitis and, on occasion, perforation with secondary diffuse peritonitis and death. This lesion in calves has not been described previously. We reviewed the postmortem cases of cecal infarction in dairy calves ≤30 d of age that had been submitted over the course of 5 y to the Tulare branch of the California Animal Health and Food Safety Laboratory System. The area of cecal infarction and the associated lesion margins were examined histologically. Ischemic necrosis of the mucosal side of the cecal wall with various degrees of neutrophilic inflammation of subjacent tissues was found consistently, and thrombosis and vascular occlusion within the areas of necrosis and inflammation was found in 21 of 34 cases. Cecal infarction cases were then compared to controls using a retrospective matched case-control study design. Cases ( n = 34) and controls ( n = 86) were compared with respect to bacteremia (as defined by pure culture of a single bacterial agent from lung and/or liver), species of bacteria isolated, and for the presence of K99 Escherichia coli (calves ≤5 d), attaching and effacing E. coli, Cryptosporidium (calves ≥5 d of age), Salmonella isolation from the intestine, rotavirus, Bovine coronavirus, and Bovine viral diarrhea virus. In addition, the presence of rumenitis or abomasitis, and omphalitis were compared between cases and controls. There were no significant differences in ruminal, abomasal, or umbilical cord tissue inflammation, or pathogen test-positive status between cases and controls.

OBJECTIVES: This study aimed to evaluate the prevalence of colonic diverticula according to age, gender, distribution, disease extension and symptoms with CT colonography (CTC). METHODS: The study population included 1091 consecutive patients who underwent CTC. Patients with diverticula were retrospectively stratified according to age, gender, clinical symptoms and colonic segment involvement. Extension of colonic diverticula was evaluated using a three-point quantitative scale. Using this data, a multivariate regression analysis was applied to investigate the existence of any correlation among variables. RESULTS: Colonic diverticula were observed in 561 patients (240 men, mean age 68 ± 12 years). Symptomatic uncomplicated diverticular disease (SUDD) was present in 47.4% of cases. In 25.6% of patients ≤40 years, at least one diverticulum in the colon was observed. Prevalence of right-sided diverticula in patients >60 years was 14.2% in caecum and 18.5% in ascending colon. No significant difference was found between symptomatic and asymptomatic patients regarding diverticula prevalence and extension. No correlation was present between diverticula extension and symptoms. CONCLUSION: The incidence of colonic diverticula appears to be greater than expected. Right colon diverticula do not appear to be an uncommon finding, with their prevalence increasing with patient age. SUDD does not seem to be related to diverticula distribution and extension. KEY POINTS: Incidence of colonic diverticula appears to be greater than expected. Right colon diverticula do not appear to be an uncommon finding. SUDD does not seem to be related to diverticula distribution and extension.

BACKGROUND: Enterobius vermicularis is an often unexpected finding in appendectomy specimen, most commonly seen in paediatric cases. Predicting the presence of E. vermicularis in the setting of appendectomy is important to avoid unnecessary appendectomy and associated morbidity. We sought to identify the incidence of E. vermicularis in a paediatric population undergoing appendectomy for clinically suspected acute appendicitis and identify predictive factors for E. vermicularis. METHODS: This study was performed in an 800-bed University Teaching Hospital, in the Republic of Ireland. We identified all paediatric appendectomies performed at our institute from January to December 2012 using prospectively maintained operating theatre logbooks. In-hospital Histopathology database, medical notes and operative findings were reviewed for each patient and relevant data recorded. Statistical analysis was performed using IBM SPSS, version 21. RESULTS: In total 182 paediatric appendectomies were performed during the year 2012 for clinically suspected acute appendicitis. Demographics included: Mean age 11.14 years (3-16), gender 1M: 1F. 58.8% of procedures were completed laparoscopically, 39% open and 2.2% were converted. The negative appendectomy rate was 22.5%. The annual incidence of E. vermicularis in acute appendicitis specimen from a paediatric cohort at our institute was 7% (1 in 14). In specimen containing E. vermicularis, 69% had no evidence of appendicitis and of those that had, no gangrene or perforation was seen. The presence of E. vermicularis in paediatric patients with RIF pain may be predicted by Eosinophilia (p = 0.016), normal WCC (p = 0.034) and normal Neutrophil count (p = 0.014). CONCLUSIONS: E. vermicularis is responsible for 7% of acute appendicitis. It is responsible for a significantly higher negative appendectomy rate which if predicted may avoid unnecessary appendectomy and associated morbidity.

BACKGROUND AND STUDY AIMS: The English National Health Service Bowel Cancer Screening Programme (NHSBCSP) is one of the world's largest organized screening programs. Minimizing adverse events is essential for any screening program. Study aims were to determine rates and to examine risk factors for adverse events. PATIENTS AND METHODS: Bleeding and perforations in NHSBCSP colonoscopies between August 2006 and January 2012 were examined. Logistic regression was used to examine risk factors for adverse events, including age, gender, polyp size, morphology, and location. For accurate attribution of adverse events, procedures with resection of only one polyp ("single-polypectomy") were analyzed in detail. RESULTS: 130â831 colonoscopies (167â208 polypectomies) were analyzed, including 30 881 single-polypectomies. Overall bleeding rate was 0.65â%, rate of bleeding requiring transfusion was 0.04â% and perforation rate was 0.06â%. Polypectomy increased bleeding risk 11.14-fold and perforation risk 2.97-fold. Cecal location (but not elsewhere in the proximal colon) and increasing polyp size were the two most important risk factors for bleeding and perforation. After adjustment for polyp size, the odds ratio (OR) relative to the distal colon for bleeding requiring transfusion after cecal snare polypectomy was 13.5 (95â%CI 3.9â-â46.4) and for perforation after cecal nonpedunculated polypectomy it was 12.2 (95â%CI 1.2â-â119.5). CONCLUSION: This is the largest study focusing on polyp-specific risk factors. We have confirmed that the greatest risk factor for both post-polypectomy bleeding and perforation is polyp size. This is the first demonstration of substantial and significantly increased risk for both noteworthy bleeding (requiring transfusion) and perforation from cecal polypectomy for a given polyp size, compared with elsewhere in the colon.

BACKGROUND: Debate surrounds the management of the macroscopically normal appendix. Current literature recommends its removal given the high incidence of microscopic appendicitis, and other unusual pathologies in the normal-looking appendix. Negative appendicectomies are reported on the decline with increased use of diagnostic radiological adjuncts. METHODS: This study analysed pathologies of the appendix over 10 years in the Pathology Department in Canberra. A positive appendicectomy was defined as acute appendicitis, faecoliths, worms, endometriosis or appendiceal tumours. We reviewed the positive appendicectomy rate over this time period. RESULTS: There were 4670 appendicectomy specimens in 2386 males (51.1%) and 2284 (49%) females. The incidence of acute appendicitis was 71.3% and the positive appendicectomy rate was 76.3%. There were significantly fewer negative appendicectomies in males (16.8%) compared with females (31.0%). There was no appreciable change in this trend over the study period. Of the positive appendicectomies, there were 129 (3.6%) faecoliths. Of these, only 39.5% had concomitant appendicitis. There were 44 (1.2%) specimens identified with worms. Of these, 40.9% had concomitant appendicitis. There were 14 cases of endometriosis of the appendix of which 36% had concomitant appendicitis. There were 58/3562 (1.6%) appendiceal tumours within the positive appendicectomy group the majority of which were carcinoid tumours (65.5%). CONCLUSION: There is a higher incidence of negative appendicectomies in women compared with men, which is similar to other published studies. Faecoliths and worms are a known cause of appendiceal colic and in our series were identified mostly in the absence of histological evidence of appendicitis.

BACKGROUND: Proximal large bowel volvulus is considered as an extremely rare surgical emergency in children. Approximately 40 cases have been reported, and because of its rarity, the diagnosis is often missed or delayed. The purpose of this study was to review the presentation, treatment, and clinical outcome of proximal large bowel volvulus. METHODS: A systematic review and analysis of the data relating to 6 patients from the author's practice and cases published in the English literature from 1965 to 2010 was performed. Detailed information regarding demographics, clinical presentation and methods of diagnosis, surgical procedure, complications, and outcome were recorded. RESULTS: Thirty-six cases of proximal large bowel volvulus were retrieved from the English literature, and 6 cases, from the author's practice. The male-female ratio was 1:1, with a median age of 10 years. There were 29 (69%) cases with neurodevelopmental delay. Clinical presentation included 29 (69%) cases with constipation, 41 (98%) with colicky abdominal pain, 42 (100%) with abdominal distension, and 35 (83%) with vomiting. Plain radiography was specific in 64% (27/42) of cases, barium enema in 100% (15/15), and computed tomography in 100% (2/2). All patients underwent surgery, with resection and primary anastomosis in 24 (57%) cases, stoma formation in 11 (26%), and detorsion of volvulus without resection in 7 (17%) cases. Six patients (14%) died postoperatively. CONCLUSION: A child with neurodevelopmental delay and a history of constipation presenting with an acute onset of colicky abdominal pain and progressive abdominal distension with vomiting should be suspected of having a cecal and proximal large bowel volvulus.

OBJECTIVE: To study diagnostic pitfalls, morbidity and mortality of adult intussusception. PATIENTS AND METHODS: Retrospective study of adult patients records operated between 1979 and 2007 with the diagnosis of adult intussusception. RESULTS: We found 41 cases of adult intussusception. The mean age was 35.2 years (standard deviation (SD)=7.1). The delay between onset and medical consultation was 15 days. The diagnosis was made pre-operatively in 11 cases. Abdominal ultrasound showed an abdominal mass in 11 cases. Ileo-ileal intussusception was most frequent (16 cases). Intussusception was secondary in 24 cases. There were seven instances of intestinal necrosis. Intestinal resection was performed in 34 cases. Surgical site infection occurred in four patients, three patients died. CONCLUSION: The pre-operative diagnosis of acute intestinal intussusception is difficult. Morbidity and mortality rates are high. Improved diagnostic investigations in developing countries could improve the prognosis of this condition.

AIM: To assess the prevalence of acquired diverticulum of the appendix (DA), including incipient forms and its possible significance as a marker of local/regional neoplasms. MATERIALS AND METHODS: The pathology database at Hvidovre Hospital was searched for appendix specimens, received between 2001 and 2010, coded for DA or for a space-occupying lesion. Slides were reviewed to determine DA status and the nature of lesions possibly causing DA. RESULT: Among 4413 appendix specimens, DA were identified in 39 (0.9%, CI 0.6% to 1.2%) cases, 17 (43.6%, 28.0% to 59.2%) of which additionally harboured an appendiceal neoplasm/neoplastic precursor, whereas this figure was 1.2% (CI 0.9% to 1.6%) for non-DA specimens (p<0.0001). Six of the 39 DA specimens comprised incipient DA, three of which coexisted with appendiceal neoplasms. In addition, local/regional non-neoplastic lesions (six cases) and colorectal carcinomas (four cases) coexisted with DA. CONCLUSION: DA has significance as a putative marker of local/regional neoplasms. Therefore, a DA specimen proved significantly more likely to harbour a neoplastic growth than a non-DA counterpart. Submission for microscopy of the entire DA specimen, whether transmural or only incipient, and a comment in the pathology report on the occasional concurrence of local/regional neoplasms in this setting seem appropriate. The observation of DA may thus provide a valuable contribution in the diagnostic process.

Introduction: Diverticular disease of the appendix is an infrequent finding in the study of surgical specimens from patients operated on for clinically suspected acute appendicitis. Our aim was to determine the prevalence of diverticular disease of the appendix in patients who underwent appendectomies based on the clinical diagnosis of acute appendicitis. Material and Method: Design: Cross-sectional study. Inclusion criteria: Patients who underwent appendectomies based on a clinical diagnosis of acute appendicitis. Studyperiod: january 2000 to december 2008. Sampling: Non-probabilistic sampling of consecutive cases. Methodology: A review was conducted of the clinical records and surgical specimens from patients who underwent appendectomies based on a clinical diagnosis of acute appendicitis. Results: Within the study period, 11.472 appendectomies were performed based on a clinical diagnosis of acute appendicitis. Ninety-four patients presented diverticular disease of the appendix (0.8 percent). The median age was 40 years and 62.8 percent were male. The disease appeared as: appendicular diverticulitis (45.7 percent), appendicular diverticulosis with acute appendicitis (28.7 percent), appendicular diverticulitis with acute appendicitis (17.0 percent), appendicular diverticulosis (5.3 percent), and appendicular pseudodiverticulosis with acute appendicitis (3.2 percent). Operative morbidity was 12.7 percent. One patient presented an adenocarcinoma of the appendix associated with diverticular disease. Conclusion: The prevalence of diverticular disease of the appendix is low in our population and the characteristics are different to reported by other authors.
Introducción: La enfermedad diverticular del apéndice cecal es un hallazgo infrecuente en apendicectomizados por sospecha clínica de apendicitis aguda. Nuestro objetivo es evaluar la prevalencia de enfermedad diverticular del apéndice cecal en pacientes apendicectomizados por sospecha clínica de apendicitis aguda. Material y Método: Diseño de estudio: Estudio de corte transversal. Criterios de inclusión: Pacientes apendicectomizados por sospecha clínica de apendicitis aguda. Período de estudio: enero de 2000 a diciembre de 2008. Muestreo: No probabilístico de casos consecutivos. Metodología: Se realizó una revisión de los registros clínicos y de las piezas quirúrgicas de los pacientes sometidos a apendicectomía por diagnóstico clínico de apendicitis aguda. Resultados: Se estudiaron 11.472 apendicectomías. Noventa y cuatro pacientes presentaron enfermedad diverticular del apéndice (0,8 por ciento). La mediana de edad fue 40 años y el 62,8 por ciento fue género masculino. La enfermedad se presentó como: diverticulitis apendicular (45,7 por ciento), diverticulosis apendicular con apendicitis aguda (28,7 por ciento), diverticulitis apendicular con apendicitis aguda (17,0 por ciento), diverticulosis apendicular (5,3 por ciento) y pseudodiverticulosis apendicular con apendicitis aguda (3,2 por ciento). La morbilidad operatoria fue 12,7 por ciento. Un paciente presentó un adenocarcinoma del apéndice cecal asociado a la enfermedad diverticular del apéndice. Conclusión: La prevalencia de enfermedad diverticular del apéndice cecal es baja en nuestra población y con características que difieren a lo reportado por otros autores.

PURPOSE: Controversy exists regarding the clinical significance of an isolated appendicolith on computed tomographic (CT) scan. We sought to determine the risk of developing appendicitis in children with an incidentally noted appendicolith. METHODS: We retrospectively reviewed all pelvic CT scans in patients 18 years or younger at a tertiary care children's hospital from October 2005 to September 2008. Patients with an appendicolith and no radiographic evidence of acute appendicitis were selected for further review. Written questionnaire and telephone follow-up were attempted in all patients. RESULTS: Two thousand nine hundred thirteen pelvic CT scans were performed during the study period. The incidence of an isolated appendicolith during the study period was 2.6% (n = 75). Seven patients underwent appendectomy at initial presentation. Nine children underwent appendectomy subsequently: 3 electively and 6 at the time of return with abdominal pain. Only 6 of these 16 appendectomy specimens had histologic evidence of appendicitis, whereas only 3 demonstrated an appendicolith. Subsequent appendicitis developed in 5.8% (n = 4) of patients with an isolated appendicolith. Follow-up was achieved in 50% of patients who did not have an appendectomy (median, 2.8 years). CONCLUSION: Children with an incidental appendicolith are at low risk for developing appendicitis. The appendicoliths were often a transient finding not confirmed on surgical pathologic condition or subsequent imaging.

OBJECTIVE: To establish the prevalence of intussusceptions involving the caecum in a population of horses admitted to a university hospital for colic. DESIGN: Retrospective clinical study METHODS: Medical records of all horses admitted to the Massey University Veterinary Teaching Hospital between 1991 and 2004 were examined for information of those horses diagnosed with an intussusception involving the caecum. RESULTS: A total of 135 horses were admitted for colic surgery during the study period and 61 horses had a diagnosis of ileocaecal (37), caecocaecal (5) or caecocolic intussusception (19) made either at surgery or necropsy. Of the horses with ileocaecal intussusception, 32 had an incomplete hand-sewn ileocaecostomy without reduction and 29 survived to discharge. All the horses with caecocaecal intussusceptions were diagnosed preoperatively via rectal examination and/or transabdominal ultrasound: 2 were euthanased at surgery and 3 survived to discharge. In the 19 horses with caecocolic intussusceptions, manually reduction at surgery was performed in 6 and 5 of them survived to discharge. A typhlectomy was performed via a colotomy in 6 horses, 3 of which survived to discharge. CONCLUSIONS: The high prevalence of intussusceptions involving the caecum seen at this referral centre may indicate a higher prevalence in New Zealand than is reported elsewhere in the world. CLINICAL RELEVANCE: Intussusceptions involving the caecum should be considered as a differential diagnosis in horses presenting with chronic low-grade colic. Transabdominal ultrasound is useful for identifying caecocaecal and caecocolic intussusceptions. Hand-sewn side-to-side incomplete ileocaecostomy is a quick, effective and safe method of surgical treatment of ileocaecal intussusceptions.
