Pathologic Analysis

Purpose: The low rate of recurrent appendicitis after initial nonsurgical management of complicated appendicitis supports the recently implemented strategy of omitting routine interval appendectomy. However, several reports have suggested an increased incidence rate of neoplasms in these patients. We aimed to identify the risk of neoplasms in the population undergoing interval appendectomy.Methods: This study retrospectively analyzed consecutive cases of appendicitis that were treated surgically between January 2014 and December 2018 at a single tertiary referral center. Patients were divided into 2 groups depending on whether they underwent immediate or interval appendectomy. Demographics and perioperative clinical and pathologic parameters were analyzed.Results: All 2,013 adults included in the study underwent surgical treatment because of an initial diagnosis of acute appendicitis. Of these, 5.5% (111 of 2,013) underwent interval appendectomy. Appendiceal neoplasm was identified on pathologic analysis in 36 cases (1.8%). The incidence of neoplasm in the interval group was 12.6% (14 of 111), which was significantly higher than that of the immediate group (1.2% [22 of 1,902], P < 0.001). Conclusion: The incidence rate of neoplasms was significantly higher in patients undergoing interval appendectomy.These findings should be considered when choosing treatment options after successful nonsurgical management of complicated appendicitis.

Common Diagnosis

Appendicitis is a common diagnosis encountered by the acute care surgeon. Management of complicated appendicitis is controversial and often involves initial nonoperative therapy with interval appendectomy. This study reviews single-institutional experience with management of complicated appendicitis with interval appendectomy and addresses an unusually high occurrence of incidental appendiceal malignancies observed with a review of relevant literature. A retrospective review of all diagnoses of appendicitis was performed over 5 years at a tertiary care center. Patient demographics, time to surgery, operative technique, pathologic diagnosis, and clinical outcomes were examined. Three hundred fifteen patients were diagnosed with acute appendicitis. Of these, 24 (7.6%) were deemed complicated and did not undergo immediate appendectomy, and 18 ultimately underwent appendectomy at our institution and were included in analysis. There were no statistical demographic or symptomatic differences between the immediate and interval appendectomy patients. Ninety-nine per cent of the immediate appendectomy patients were treated laparoscopically; 78 per cent of the interval group underwent attempted laparoscopic treatment with 56 per cent completed without conversion to open ( P < 0.01). Neoplasms were discovered in 1 per cent of the acute appendectomy group and 28 per cent of the interval appendectomy group ( P < 0.0001). Two of the three neoplasms in the acute group were carcinoid, whereas three of the five neoplasms in the interval group were adenocarcinoma. Surgeons should consider appendiceal or colonic neoplasms in cases of complicated appendicitis when nonoperative management is considered. This is most important in patients older than 40 years, in those who forego interval appendectomy, or in those who could be lost to follow-up.

Abstract Aims The mainstay of acute appendicitis treatment is a surgical approach. However, in the tumultuous COVID-19 era, the approach to acute appendicitis management has altered. We sought to assess the applicability of the new RCS COVID-19 guidance after resolution of the global pandemic. Methods A retrospective study was conducted on 244 patients presenting between 01/03/2020 and 17/07/2020. Three sources of data were sought: patients presenting to A&E with signs of appendicitis, operative logs for patients who underwent removal of their appendix and all CT/US scans where the clinician had queried appendicitis in the request. Results 139 patients were treated conservatively with antibiotics (57.0%). 35 (25.2%) represented within 6 months. Conservative treatment was successful in 92.1% of cases. 65 appendectomies were completed during that time. 45 cases presented acutely whereby the surgical management of acute appendicitis was the primary choice. The decision to operate was due to: 13 (20%) because the patient was 16 or younger. 4 cases presenting with signs of severe sepsis. 4 cases had a complicated appendicitis on their imaging results. 22 (33.8%) cases were completed without initial conservative management. 9 (3.7%) cases failed conservative treatment thus requiring surgical management. 11 (4.5%) cases represented within 6 months due to recurrent appendicitis despite successful antibiotic treatment. Therefore, the recurrence rate following conservative treatment was 7.9%. Conclusions There was mixed adherence to the new guidance. Surgical management remains the best approach towards acute appendicitis. However, excellent results can still be achieved with appropriately targeted antibiotic therapy.

Abstract Introduction To standardize care and reduce resource utilization, we implemented a standardized protocol (SP) for the nonoperative treatment of complicated appendicitis. Materials and Methods We conducted a prospective, historically controlled, study of patients <21 years with complicated appendicitis managed nonoperatively using an SP from January 2017 to November 2018. The primary outcomes included length of stay (LOS), antibiotic days, peripheral inserted central catheter (PICC) utilization, discharge on intravenous antibiotics, and predischarge imaging. Secondary outcomes were protocol adherence and the rates of adverse events (AE) including return to emergency department (ED), readmission, failure of nonoperative treatment, and interval appendectomy complications. Results Protocol adherence was 67.9%. In total, 741 children were treated for appendicitis of which 58 (30 pre-SP and 28 post-SP) were treated nonoperatively for complicated appendicitis at presentation. Patients were well matched for age, admission white blood cell, sex, body mass index, race, and the proportion requiring percutaneous drainage. After implementing the SP, fewer children had PICCs (100.0 vs. 57.1%, p ≤ 0.001), fewer were discharged on intravenous antibiotics (90.0 vs. 42.9%, p < 0.001), and total antibiotic days were reduced (14.0 vs. 10.0, p = 0.006). There was no difference in LOS (5.5 vs. 6.0 days, p = 0.790) or the proportion undergoing ultrasound (36.7 vs. 39.3%, p = 0.837) or computed tomography scan (16.7 vs. 3.6%, p = 0.195) prior to discharge. There were nonsignificant trends toward reduced AEs (46.7 vs. 35.7%, p = 0.397), returns to ED (40.0 vs. 28.6%, p = 0.360), and readmissions (26.7 vs. 17.9%, p = 0.421). The proportion failing nonoperative treatment (10.0 vs. 3.6%, p = 0.612) and experiencing complications of interval appendectomy (3.3 vs. 3.6%, p = 0.918) were not significantly different. Conclusion Implementing an SP for treating complicated appendicitis nonoperatively reduced resource utilization without negatively affecting clinical outcomes.
