Abstract
BACKGROUND Acute appendicitis in children is the most common condition requiring urgent evaluation and surgery in the emergency department. At times, despite the appendix being seen on ultrasound (US), there can be discrepancy as to whether a patient has clinical appendicitis. Secondary findings suggestive of appendicitis can be helpful in identifying and evaluating these children. OBJECTIVE The aim of this study was to determine if specific US findings and/or laboratory results are predictive of appendicitis in children with a visualized appendix on US. METHODS A prospective study was conducted on children (birth to 18 years) presenting to the pediatric emergency department with suspected appendicitis who underwent right-lower-quadrant US. Ultrasound findings analyzed appendix diameter, compressibility, increased vascularity, presence of appendicolith, inflammatory changes, right-lower-quadrant fluid near the appendix, lower abdominal fluid, tenderness during US, and lymph nodes. Diagnosis was confirmed via surgical pathology. RESULTS There were 1252 patients who enrolled, 60.8 (762) had their appendix visualized, and 39.1 (490) did not. In children where the appendix was seen, 35.2% (268) were diagnosed with appendicitis. Among patients with a visualized appendix, the likelihood of appendicitis was significantly greater if the appendix diameter was 7 mm or greater (odds ratio [OR], 12.4; 95% confidence interval [CI], 4.7-32.7), an appendicolith was present (OR, 3.9; 95% CI, 1.5-10.3), inflammatory changes were seen (OR, 10.2; 95% CI, 3.9-26.1), or the white blood cell (WBC) count was 10,000/μL (OR, 4.8; 95% CI, 2.4-9.7). A duration of abdominal pain of 3 days or more was significantly less likely to be associated with appendicitis (OR, 0.3; 95% CI, 0.08-0.99). The absence of inflammatory changes, WBC count of less than 10,000/μL, and appendix diameter of 7 mm or less had a negative predictive value of 100%. CONCLUSIONS When the appendix is seen on US but diagnosis of appendicitis is questioned, the absence of inflammatory changes, WBC count of less than 10,000/μL, and appendix diameter of 7 mm or less should decrease suspicion for appendicitis.

Stump Invagination Versus Simple Ligation in Open Appendicectomy: A Systematic Review and Meta-Analysis. Int Surg 2019; 100:1199-206. [PMID: 26595494 DOI: 10.9738/intsurg-d-15-00074.1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/17/2022] Open
Abstract
The aim of this meta-analysis was to compare the superiority of stump closure between stump invagination (SI) and simple ligation (SL) during open appendicectomy (OA). The literature searching was conducted in MEDLINE, EMBASE, the Cochrane Library, and http://scholar.google.com . Available data was extracted by 3 independent reviewers. The clinical outcomes were analyzed by meta-analytic software to compare the difference between 2 methods during OA. The pooled odds ratios (ORs) and weighted mean differences (WMDs) with 95% confidence intervals (95% CIs) were obtained by using fixed effect model. Eleven randomized controlled trials (RCTs) were finally included in this study involving 2634 patients. Postoperative pyrexia and infections were similar between SL and SI groups, respectively, but the former group had a shorter operative time (WMD: 8.72; 95% CI: 6.87-10.56; P < 0.00001); less incidence of postoperative ileus (WMD: 2.02; 95% CI: 1.36-3.01; P = 0.0005); and quicker postoperative recovery (WMD: 0.30; 95% CI: 0.11-0.48; P = 0.002). The above results were based on 5, 11, 4, 11, and 9 articles, respectively. The clinical results revealed that SL was significantly superior to SI. SL should be suggested during OA.

Abstract
OBJECTIVES This study aims to investigate the optimal outer appendiceal diameter via ultrasound for the diagnosis of acute appendicitis. METHODS A retrospective chart review was conducted on patients (ages, 2-18 years) presenting to an urban pediatric emergency department between January 1, 2009 and December 31, 2010 with suspected acute appendicitis. Children were considered as having "suspected acute appendicitis" if they (1) presented with acute abdominal pain and had either a surgical consult or an abdominal ultrasound, or (2) presented or transferred with the stated suspicion of acute appendicitis. Pathology reports were used to confirm the diagnosis of appendicitis. The appendiceal diameters were determined by board-certified pediatric radiologists. RESULTS A total of 320 patient charts were reviewed (females, 57%; mean age, 10.9; SD, 3.9). Seventy-two percent (N = 230) of the patients screened positive for acute appendicitis via ultrasound, 69% (N = 222) had confirmed acute appendicitis, 75% (N = 239) of the ultrasound reports included an outer appendiceal diameter. Overall, ultrasound was found to be highly sensitive (91%) and moderately specific (74%). With an outer appendiceal diameter of 6 mm as a cutoff, ultrasound had an excellent sensitivity (100%) but poor specificity (43%). With an outer diameter of 7 mm as a cutoff, sensitivity decreased to 94% but specificity increased to 71%. With increasing cutoff size, the sensitivity decreased and specificity increased. CONCLUSIONS Our data suggest that the optimal outer appendiceal diameter for the diagnosis of acute appendicitis should be 7 mm instead of the currently used 6 mm.

Abstract
BACKGROUND Acute appendicitis is currently one of the most common surgical emergencies. Intra-abdominal abscesses (IAA) are a fearsome complication, which may occur. Irrigation during the appendectomy is one of the factors suggested to affect the rates of IAA. We sought to investigate the evidence regarding the use of irrigation versus suction alone and the development of IAA after laparoscopic appendectomy for complicated appendicitis. METHODS We searched PubMed, Scopus, Embase, Cochrane, and the Web of Science through November 10, 2017, according to Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. We extracted information of interest, including rates of postoperative (IAA), and performed meta-analysis using random-effects model using the RevMan software. RESULTS We identified five eligible studies with 2511 patients in total. Use of irrigation overall did not demonstrate significant increase in IAA (odds ratio [OR] = 2.39, 95% confidence interval [CI; 0.49, 11.74], P = 0.28). For the adult subpopulation, the use of irrigation was associated with nonsignificant lower odds of IAAs (OR = 0.42, 95% CI [0.15, 1.16]), whereas in pediatric with nonsignificant higher risk (OR = 2.98, 95% CI [0.25, 35.34]). Performance of irrigation led to the addition of, on average, 7 min to the duration of the operation (mean difference = 7.16, 95% CI [3.23, 11.09], P < 0.001). Irrigation did not affect postoperative length of stay (mean difference = -0.80, 95% CI [-2.30, 0.69], P = 0.29). CONCLUSIONS Performance of irrigation during laparoscopic appendectomy does not seem to prevent the development of IAA in neither adults nor pediatric patients.

Abstract
Ultrasound (US) and laboratory testing are initial diagnostic tests for acute appendicitis. A diagnostic dilemma develops when the appendix is not visualized on US. Objective: To determine if specific US findings and/or laboratory results predict acute appendicitis when the appendix is not visualized. Methods: A prospective study was conducted on children (birth-18 yrs) presenting to the pediatric emergency department with suspected acute appendicitis who underwent right lower quadrant US. Children with previous appendectomy, US at another facility, or eloped were excluded. US findings analyzed: inflammatory changes, right lower quadrant and lower abdominal fluid, tenderness during US exam and lymph nodes. Diagnoses were confirmed via surgical pathology. Results 1252 subjects were enrolled, 60.8% (762) had appendix visualized and 39.1% (490) did not. In children where the appendix was not seen, 6.7% [33] were diagnosed with appendicitis. Among patients with a non-visualized appendix, the likelihood of appendicitis was significantly greater if: inflammatory changes in the RLQ (OR 18.0, 95% CI 4.5-72.1), CRP >0.5 mg/dL (OR 2.64, 95% CI 1.0-6.8), or WBC > 10 (OR 4.36, 95% CI 1.66-11.58). Duration of abdominal pain >3 days was significantly less likely associated with appendicitis in this model (OR 0.34, 95% CI 0.003-0.395). Combined, the absence inflammatory changes, CRP < 0.5 mg/dL, WBC < 10, and pain, ≤3 days had a NPV of 94.0%. Conclusion When the appendix is not visualized on US, predictors for appendicitis include the presence of inflammatory changes in the RLQ, an elevated WBC/CRP and abdominal pain <3 days.

Choksuwattanasakul M. Incidental appendectomy during mini incision post-partum sterilization (Chokchai technique): A prospective cross-sectional study. J Obstet Gynaecol Res 2017; 43:1863-1869. [PMID: 28892212 DOI: 10.1111/jog.13458] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2016] [Revised: 05/30/2017] [Accepted: 06/30/2017] [Indexed: 12/12/2022]
Abstract
AIM We aimed to determine the success rate of incidental appendectomy during post-partum sterilization (PPS) using the Chokchai technique and to compare the postoperative morbidity between patients who underwent this procedure with those who underwent simple PPS. METHODS Appendectomy during PPS was performed in 141 patients from 1 May 2012 to 30 April 2014. The control group consisted of 182 simple PPS patients. Primary outcomes were the success rate of the procedure and secondary outcomes were postoperative morbidity and complications. RESULTS The success rate of this procedure was 98.6%. There was no statistically significant difference in intraoperative blood loss, hospital length of stay, or postoperative morbidity. Appendectomy added 7.5 min to the total procedure. Intravenous sedation requirements were 13.7% and 33.3% in the control and study groups, respectively. Pathologic evaluation of resected appendices revealed 15 abnormalities (10.8%), including two cases of periappendicitis (1.4%). CONCLUSION When carried out by experienced surgeons and with appropriate anesthesia, incidental appendectomy during PPS is safe. The Chokchai technique (approach through a small periumbilical incision) achieved a high success rate and resulted in minimal scar. Incidental appendectomy not only prevents any future appendicitis but also helps to detect periappendicitis and treat its primary cause. However, this is an option for only selected patients who are clearly informed about the possible risks and benefits of the procedure.

Abstract
PURPOSE: To evaluate the efficacy of the use of LigaSureTM in appendectomy, with or without acute inflammatory process, and to compare with simple ligature and conventional therapy. METHODS: A total of 30 rabbits (Oryctolagus cuniculus) randomly allocated in two groups, group A and B, of 15 animals each were used. The group A without acute appendicitis and the group B with acute appendicitis were submitted to appendectomy. After, the groups were subdivided into three groups, each group containing five rabbits submitted to simple ligature, conventional therapy and application of LigaSureTM. We assessed macroscopic and microscopy parameters of appendiceal stump and operative wound. RESULTS: The group with acute appendicitis that LigaSureTM was applied had fibrosis in 100% of animals, as well as in the other operative techniques used. It suggested that application of LigaSureTM is efficient as other techniques used in healing of appendiceal stump. CONCLUSIONS: The application of LigaSureTM induces the formation of fibrosis in the appendiceal stump. The technique proved efficacy to induce enough fibrous tissue to obstruct leakage of enteric content.

Abstract
BACKGROUND Appendectomy is one of the commonest procedures in surgery. In spite of various investigations used to improve the accuracy of diagnosis, the rate of normal appendices removed is still about 15-30%. Many studies have investigated the role of C-reactive protein (CRP) in acute appendicitis, but with conflicting results. METHODS In a prospective, double blind study, blood for the measurement of serum C-reactive protein was collected pre-operatively from 192 children before going to the operating theatre for appendectomy. The histopathology was grouped into positive (acute appendicitis) and negative (normal appendix) and this was correlated with CRP values. RESULTS CRP was normal in 14 out of 33 negative explorations (normal appendix on histopathology). The specificity and sensitivity of serum CRP was 42% and 91% respectively. The predictive value of a positive (raised CRP) and negative (normal CRP) test is 88% and 48% respectively. CONCLUSION We conclude that neither raised nor normal CRP value is helpful in the diagnosis of acute appendicitis. CRP is not a good tool for helping the surgeon make the diagnosis of appendicitis and it should not be measured in suspected appendicitis.

Abstract
BACKGROUND/PURPOSE Open wound management has long been the most common practice after appendectomy for perforated appendicitis. Primary closure, however, has recently been advocated to reduce cost and morbidity. The aim of this study was to compare the results of open wound management and primary wound closure in adult patients (age, > or =15 years) with perforated appendicitis. METHODS Hospital records of 390 patients (age, > or =15 years) who underwent appendectomy between January 2002 and December 2004 were reviewed to identify surgical wound infection (SWI) and pathologic diagnosis. Perforated appendicitis was the indication for appendectomy in 65 of these patients. The incision wounds in these 65 patients were closed primarily in 41 and left open at the end of the operation in 24. The duration of symptoms, white blood cell count, operative time, incidence of SWI, length of stay (LOS) and readmission rate were compared between patients with these two different methods of wound management. RESULTS Patients whose wounds were closed primarily had a higher incidence of SWI (43.9% vs. 4.2%, p < 0.001) and longer LOS (10 days vs. 7.9 days, p = 0.044). The readmission rate was also higher for patients whose wounds were closed primarily; however, this difference was not significant. CONCLUSION Open wound management may be preferable to primary wound closure for perforated appendicitis in adults because of a lower incidence of SWI and a shorter LOS. Randomized clinical trials, however, are needed to establish these findings.

Abstract
PURPOSE To evaluate partial or total ischemia, through ligature with an unabsorbed thread of vessels from the vermiform appendix of rabbits, as well as the mechanical obstruction, through ligature with an unabsorbed thread at the basis of the vermiform appendix, at 1 cm from the cecum, of the acute appendicitis disease. To evaluate the histology of the appendix (normal and affected). To study the bacterium flora resident in the vermiform appendix (normal and affected) and the exudates peritonitis. METHODS Seventy-two male rabbits (Oryctogalus cuniculus), from New Zealand lineage were used, weighing approximately 3,000 grams. The animals were divided into: pilot (A), bacterium flora (B), control (H) and experimental (C, D, E, F and G) groups, and were observed in periods of 96 and 192 hours. It was done the ligature with an unabsorbed thread of vessels from the meso appendix, and the base of the appendix within 1 cm from the cecal. In the (C) experimental group, the mechanical obstruction was carried out. In the (D, E, F and G) experimental groups, the ischemic model was used, and in the (H) control group, only the surgical simulation was done. RESULTS In the control group (H), the acute appendicitis didn't happen. In the experimental group (C, D, E, F and G) the acute appendicitis happened. CONCLUSION The method used causes acute appendicitis with distinct anatomopathological alterations. The main bacteria found at the physiological flora of the enteric juice from the vermiform appendix and at the exudates peritonitis was the Escherichia coli.

Abstract
Although appendectomy is the most commonly performed emergency operation septic complications of appendectomy remain a major source of morbidity. Historically, advanced appendicitis has been treated by appendectomy with cecostomy and/or drainage tubes. Our objective was to evaluate the use of ileocecal resection for the immediate treatment of advanced appendicitis. We examined the cases of all patients undergoing ileocecal resection for appendicitis from August 1989 through April 2000. There were 92 patients (60 male and 32 female) with a median age of 34 (range 6–71). Abdominal pain was present in 98 per cent of patients with duration of 5.1 ± 0.6 days. Right lower quadrant tenderness was present in 91 per cent with accompanying right lower quadrant mass in 30 per cent. Temperature on admission was 38.0 ± 0.1° C with a white blood cell count of 15,300 ± 500. Preoperative radiological studies included abdominal X-rays (33), contrast enemas (two), CT scans (41), and abdominal ultrasound (17); these studies yielded a correct preoperative diagnosis in 89 per cent. Previous appendectomy had been performed in six patients with failed percutaneous drainage of intra-abdominal abscesses in five. There were 94 cecal resections performed in 92 patients. The extent of surgical resection varied between patients and ranged from partial cecectomy (34) to ileocecectomy (55) to ileocecectomy with diverting ileostomy (five). Intra-abdominal abscesses were present at operation in 46 cases (50%), and drains were placed in 38 (41%). Skin incisions were packed open in most cases (65); there was skin closure in 27. There was no mortality encountered in this period. There were 25 complications in 23 patients (25%). Complications included postoperative abscess (10; 11%), wound infection (10; 11%), partial small bowel obstruction (two) and pulmonary embolus (one). Reoperation was required in seven patients and CT-guided percutaneous drainage in five patients. Anastomic leaks occurred in two cases of partial cecectomy and required conversion to ileocecectomy. Mean hospital stay was 10.5 ± 1.0 days with adjusted hospital costs of $31,689 ± 3018. We conclude that definitive treatment of advanced appendicitis can be performed by resection of the involved areas of the ileocecum. This can be accomplished with a primary anastomosis obviating the need for ileostomy and secondary operation. This aggressive surgical approach may reduce infectious complications and reduce hospital costs.

Abstract
BACKGROUND Acute appendicitis is the most common condition requiring an emergency abdominal operation in childhood. In the present study, we analyzed the frequency of portal and systemic bacteremia in 42 patients with acute appendicitis and determined the microbial agents responsible for an acute appendicitis and for portal and systemic bacteremia. METHODS Appendectomies were performed on 50 young patients (5-18 years of age), as well as clinical and bacteriological tests. Six independent samples from each patient isolated from the peripheral vein, superior mesenteric vein, appendix and peritoneum were obtained prior to surgery, during surgery and after surgery for biochemical, immunologic and bacteriologic examination. RESULTS Pathohistology confirmed the diagnosis of appendicitis in 42 patients, while in the other eight patients there were no obvious pathologic findings, so they served as a control group. Of 50 patients with a clinical appearance of acute appendicitis, in 19 patients (38%) we detected portal bacteremia in the mesenteric vein, while in only three cases (6%) did we find systemic bacteremia detected from the peripheral vein. Furthermore, bacteriologic analysis revealed that Bacteroides spp. and Escherichia coli were the predominant species isolated. CONCLUSIONS The results presented in this paper suggests that portal bacteremia did not influence peripheral blood reactions. Furthermore, in the present study we have found a positive correlation between the smear and bacteremia of the superior mesenteric vein, but not with the bacteremia of systemic blood.

Abstract
OBJECTIVES To survey and review the incidence of appendectomy performed during radical cystectomy and urinary diversion. We were interested in the reasons behind the decision and if continent diversions have changed the policy. METHODS We performed a selective survey among urologists in academic centers throughout the United States regarding their practice of incidental appendectomy during radical cystectomy. We also reviewed the literature regarding the rationale for incidental appendectomy in general and during radical cystectomy in particular. RESULTS Among the 13 departments and 26 urologists replying to the survey, 9 (69%) departments and 20 (77%) individual clinicians are not performing routine incidental appendectomy. In 2 departments, it is considered a matter of choice, and, in 4 (31%) departments, appendectomy is performed routinely. Many believe that the low risk of subsequent appendicitis does not justify the procedure and that the appendix may be useful for future reconstruction. A review of the literature suggests that incidental appendectomy during radical cystectomy is not necessary. CONCLUSIONS Incidental appendectomy during radical cystectomy is not necessary and is no longer being performed in many academic centers. The risk of subsequent appendicitis is extremely low. The decision may depend on the form of urinary diversion planned.

Abstract
The evolving phases of acute appendicitis were studied experimentally. Sixty female rabbits (Oryctogalus cuniculus) of New Zealand lineage weighing about 2510 to 3040 g were divided in two groups: a control group and experimental group. The experimental group was divided into three subgroups for observation after 12, 24 and 48 hours of the operation, that consisted on a 4-0 polypropylene circular suture at 8 cm from the distal part of the cecal appendix. The control group was sham operated. The macroscopic exam (increase of the appendix volume, necrosis, perfuration, adherence and secretion in the abdominal cavity) and the microscopic finding showed a progression in the anatomopathological alterations. There was a close relationship between the histopathological findings and time after the appendiceal obstruction. We conclude that the method causes acute appendicitis and that the anathomo pathological alterations depends on the time elapsed between the operation and the postoperation findings.

Abstract
Most complications after appendectomy occur within 10 days; however, we report herein the unusual case of a patient in whom a wound abscess was detected more than 10 years after an appendectomy. A 26-year-old woman presented to our hospital with nausea and vomiting, pain, and a mass in the right lower abdominal wall. She had undergone an appendectomy 11 years previously. Physical examination revealed a tender mass, 5 cm in diameter, under the appendectomy scar. An abdominal ultrasonography demonstrated a low-echoic mass lesion measuring 9.0 x 5.0 x 2.0 cm. Incision of the connective tissue revealed about 3 ml of cream-colored and odorless fluid in the abscess cavity. Fistulography revealed an abscess cavity not communicating with the bowel lumen. Floss was discovered in the connective tissue and removed. Debridement of the abscess wall was performed and a piece of the wall was sent for histologic examination. Pathological examination revealed panniculitis of the subcutaneous tissue, and panniculitis with granulation and granuloma of the abscess wall. This case report demonstrates that a preoperative diagnosis should be based not on one finding, but on all findings collected, inclusively.

Abstract
Open wound management after perforated appendicitis was common practice but, recently, primary closure has been advocated to reduce costs and morbidity. Hospital records from 319 adults who underwent appendectomy from 1993 to 1996 were reviewed to identify surgical wound infections (SWIs) and examine risk factors. Information about age, length of stay (LOS), operative time, white blood cell count, and antibiotic administration were obtained. Perforation was either noted at operation or identified microscopically by the pathologist. If primary wound closure was performed, patients with acute appendicitis and perforation had a 4-fold higher readmission rate, a 5-fold increase in SWI, and twice the LOS compared with patients with acute appendicitis without perforation. Patients with grossly perforated acute appendicitis had no difference in LOS if the wound was treated open or closed primarily. No patient with microscopic perforation and primary wound closure developed SWI. Primary wound closure after acute appendicitis was safe in the absence of clinical perforation. In the presence of clinical appendiceal perforation the wound should be left open.

Abstract
Hollow viscus injuries are usually managed with few complications. However, if their diagnosis is delayed, or if reparative suture closure should fail, the patient is placed at risk of multiple organ failure. This article presents diagnostic approaches, emphasizing imaging modalities, and therapeutic strategies for three clinical scenarios of hollow viscus perforation: 1) acute appendicitis, 2) gastroduodenal peptic ulcer disease, and 3) trauma.

Abstract
When contemplating converting from open to laparoscopic appendectomy, a prudent surgeon should consider the anticipated learning curve. To evaluate this we reviewed our experience with 20 sequential patients representing this transition. We found the learning curve was brief and did not compromise clinical results. A reduction in hospitalization time without a rise in total hospital costs should encourage the experienced laparoscopic surgeon to consider laparoscopic appendectomy as a viable alternative to standard laparotomy in the resection of the acutely inflamed appendix.

Abstract
Laparoscopic methods are becoming increasingly popular in surgery. In the course of a review concerning laparoscopic appendectomy undertaken up to 31 December 1993 all publications were evaluated by computer-assisted research. Out of a total of 90 publications only 14 deal with the comparison of the laparoscopic versus open appendectomy. Two prospective randomized studies are published. Because of the low number of patients the evaluation of the laparoscopic method is not yet definite.

Abstract
The diagnosis of acute appendicitis is usually made from the history and physical examination. Recently, abdominal ultrasonography (US), laparoscopy, computerized tomography (CT), and barium enema (BE) have been used in the preoperative evaluation of patients with presumed appendicitis in order to improve the diagnostic accuracy. However, the usefulness of these tests in verifying the diagnosis of appendicitis has not been established. We reviewed the medical records of 203 patients who underwent appendectomy. One hundred patients were surgically treated before 1984 (group I) and 103 patients underwent surgery after 1988 (group II). Patients in group II were more likely to have preoperative US, laparoscopy, CT, or BE (24 in group II versus 3 in group I, p < 0.05). When groups I and II were compared, the rates of perforation (27% versus 20%), normal appendectomy (8% versus 11%), and the interval between admission and operation (12.2 hours versus 10.7 hours) and length of hospitalization (5.0 days versus 5.1 days) were not significantly different. We concluded that although adjunctive testing may be beneficial in selected patients, its routine use in patients suspected of having appendicitis cannot be advocated at present.

Abstract
This is a prospective and randomized study of 100 patients with acute appendicitis who were less than 10 years old, in which four different antibiotic regimens commonly in use against gram-negative and anaerobic bacteria were compared in terms of postoperative septic complications. The antibiotics were begun immediately preoperatively and continued for five days. Ten percent of the patients developed infection complications, with 4% requiring further surgery. The best results were obtained with cefoxitin (4% of infection), metronidazole plus amikacin and latamoxef (8%), while the regimen of clindamycin plus amikacin was associated with the greatest number of complications (20%). On analyzing the main microbiologic findings of the study, we conclude that some sort of antibiotic treatment is indicated in all types of appendicitis, due to the occult presence of bacteria in the peritoneal cavity, even without clinical evidence of gangrene or perforation. Further, we emphasize the significance of Streptococcus faecalis as being responsible, along with Escherichia coli and Bacteroides fragilis, for serious postoperative complications.

Abstract
All patients greater than 50 years of age (N = 96) admitted with a pre- or postoperative diagnosis of acute appendicitis from 1971 to 1980 were reviewed. A comparative series of 91 patients aged 25 to 50 years was similarly reviewed. Noninflammatory diseases of the appendix and incidental appendectomies were excluded. Detailed study of symptoms, clinical presentation, laboratory evaluation, radiographic evaluation, concomitant diseases, hospital course, surgical findings, complications, and mortality were completed. Comparison of patients aged 25 to 50 to patients older than 50 years revealed a statistically significant increased incidence of perforation in the older group (p less than 0.0001). Sixty-five per cent of the older group showed greater incidence of perforation. Further analysis of this series yields the hypothesis that the increased incidence of perforation is related to a significant decrease in the frequency of classic presentation in the greater-than-50 age group, a significant decrease in frequency of correct admission diagnosis and a significant delay between admission and surgical procedure in the older group. A more rapid pathophysiologic progression of appendicitis with increasing age was noted. A much higher percentage of older patients was undiagnosed until the surgical procedure. In this group, there was a longer duration of symptoms, less frequent classic presentation, and decreased frequency of right lower quadrant guarding and tenderness as compared to patients with correct diagnosis prior to surgery. Complications were much more frequent in older patients and higher still in those with perforation. Analysis of findings by decade of life revealed an anticipated high incidence of perforated appendicitis in patients greater than 50, but also showed a continuation of the high incidence of perforation into the decade 40 to 50. There were three deaths in the entire study group (1.6%) all occurring in the older age group with postoperative sepsis.
