Huerta CT, Ramsey WA, Lynn R, Voza FA, Saberi RA, Gilna GP, Parreco JP, Thorson CM, Sola JE, Perez EA. Outcomes of Incidental Appendectomy During Ovarian Operations in a National Pediatric Cohort. J Surg Res 2023; 291:496-506. [PMID: 37536191 DOI: 10.1016/j.jss.2023.06.043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 05/17/2023] [Accepted: 06/13/2023] [Indexed: 08/05/2023]
Abstract
INTRODUCTION The utility of incidental appendectomy (IA) during many ovarian operations has not been evaluated in the pediatric population. This study sought to compare outcomes after ovarian surgery with IA in the pediatric population. METHODS Females (≤20 y old) undergoing ovarian surgeries (oophorectomy, detorsion and/or drainage) were identified from the Nationwide Readmissions Database (2016-2018). Those with appendicitis were excluded. A propensity score-matched analysis (PSMA) with 46 covariates (demographics, comorbidities, hospitalization factors, etc.) was performed between those receiving ovarian surgery with or without IA. RESULTS There were 13,202 females (median age 17 [IQR 14-20] y old) who underwent oophorectomy (90%), detorsion (26%), and/or ovarian drainage (13%). There were more episodes of torsion in the PSMA cohort receiving ovarian surgery alone (17% versus 10% IA; P = 0.016), while other indications (ovarian mass, cyst) were similar. Open (66% versus 34% laparoscopic) IAs were more frequent. Length of stay (LOS) was longer for those undergoing IA (3 [2-4] versus 2 [2-4] days ovarian surgery alone; P < 0.001). There was a higher rate of postoperative GI complications in the IA cohort. Subgroup analysis of those undergoing laparoscopic operations demonstrated no difference in LOS or postoperative complications between patients undergoing IA or not. CONCLUSIONS These data indicate that IA in pediatric ovarian operations is associated with longer LOS and higher GI postoperative complications. However, laparoscopic IA was not associated with higher cost, complications, LOS, or readmissions. This suggests that IA performed during ovarian surgeries in select patients may be cost-effective and worthy of future study.

Chen YW, Hsu PK, Lin SP, Chen HH. Appendicitis is associated with an increased risk of systemic lupus erythematosus: a nationwide, population-based, case-control study. Clin Rheumatol 2023:10.1007/s10067-023-06585-w. [PMID: 37040052 DOI: 10.1007/s10067-023-06585-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 03/20/2023] [Accepted: 03/22/2023] [Indexed: 04/12/2023]
Abstract
OBJECTIVE To examine the association between appendicitis and the risk of systemic lupus erythematosus (SLE). METHODS Using claims data from the 2003-2013 Taiwanese National Health Insurance Research Database, we selected 6054 patients with newly diagnosed SLE from 2007 to 2012 and 36,324 age-, sex- and year of SLE diagnosis date-matched (1:6) non-SLE controls. After controlling for potential confounders, a multivariable conditional logistic regression model was used to calculate the adjusted odds ratio (aOR) with 95% confidence interval (CI) for the association of appendicitis history with SLE. Sensitivity analyses were conducted using various definitions of appendicitis. Subgroup analyses were conducted to examine possible modification effects by age, gender, level of urbanization, income and Charlson Comorbidity Index (CCI). RESULTS The average age of patients was 38 years old in both groups. The proportion of females was 86.5%. 75 (1.2%) of SLE cases and 205 (0.6%) of non-SLE controls had appendicitis history before the index date. After adjusting for potential confounding factors, appendicitis was associated with a higher risk of SLE (aOR, 1.84; 95% CI, 1.34-2.52), and such association remained robust after variation of appendicitis definition. No significant modification effects were found for the association between appendicitis and SLE by age, gender, urbanization level, income and CCI. CONCLUSION This nationwide, population-based case-control study demonstrates an association between appendicitis and incident SLE. Lack of individual smoking status is a major limitation. Key Points • Appendicitis was significantly associated with an increased risk of SLE. • Such association remained robust using various definitions of appendicitis.

Abstract
BACKGROUND: There is debate whether astronauts traveling to space should undergo a prophylactic splenectomy prior to long duration spaceflight. Risks to the spleen during flight include radiation and trauma. However, splenectomy also carries significant risks.METHODS: Systematic review of data published over the past 5 decades regarding risks associated with splenectomies and risks associated with irradiation to the spleen from long duration spaceflight were analyzed. A total of 41 articles were reviewed.RESULTS: Acute risks of splenectomy include intraoperative mortality rate (from hemorrhage) of 3-5%, mortality rate from postoperative complications of 6%, thromboembolic event rate of 10%, and portal vein thrombosis rate of 5-37%. Delayed risks of splenectomy include overwhelming postsplenectomy infection (OPSI) at 0.5% at 5 yr post splenectomy, mortality rate as high as 60% for pneumococcal infections, and development of malignancy with relative risk of 1.53. The risk of hematologic malignancy increases significantly when individuals reach 40 Gy of exposure, much higher than the 0.6 Gy of radiation experienced from a 12-mo round trip to Mars. Lower doses of radiation increase the risk of hyposplenism more so than hematologic malignancy.CONCLUSION:For protection against hematologic malignancy, the benefits of prophylactic splenectomy do not outweigh the risks. However, there is a possible risk of hyposplenism from long duration spaceflight. It would be beneficial to prophylactically provide vaccines against encapsulated organisms for long duration spaceflight to mitigate the risk of hyposplenism.Siu M, Levin D, Christiansen R, Kelly E, Alouidor R, Kamine TH.

Abstract
BACKGROUND The utility of incidental appendectomy, appendectomy during another index surgery in the absence of appendicitis, has not been evaluated in the pediatric population during cholecystectomy. This study sought to compare nationwide outcomes after cholecystectomy with incidental appendectomy in children. METHODS Patients ≤ 18 years old who underwent cholecystectomy from 2010-2014 were identified from the Nationwide Readmissions Database. A propensity score-matched analysis (PSMA) with > 40 covariates including demographics, comorbidities, and hospitalization factors was performed between those receiving cholecystectomy alone versus incidental appendectomy at the time of cholecystectomy. RESULTS 34,390 patients underwent cholecystectomy (median age 15 [13-17] years). Laparoscopic (92%) approach was utilized most frequently, with 2% requiring conversion to open cholecystectomy. PSMA demonstrated a higher frequency of perforation or laceration of adjacent organs occurring in those receiving cholecystectomy alone during index admission. No significant differences in readmissions within 30 days or the calendar year were detected. Those undergoing cholecystectomy alone had higher overall readmission costs ($11,783 [$4942-$39,836] vs. $6,100 [$2358-$19,719] cholecystectomy with appendectomy; p = 0.010). CONCLUSION This nationwide PSMA indicates that incidental appendectomy in pediatric cholecystectomies is not associated with higher postoperative complications, cost, or readmissions. This suggests that incidental appendectomy during cholecystectomy is safe, cost-effective, and worthy of future study. LEVEL OF EVIDENCE Level III.

Abstract
Appendicectomy is a common pediatric surgical procedure performed by trainees and surgeons with varying reported outcomes. It is a benchmark procedure for trainee progression and training benefits should be weighed against patient safety and perioperative outcomes. This systematic review and meta-analysis investigated any differential perioperative outcomes dependent on the grade of the operating surgeon. A systematic literature review and meta-analysis were performed comparing outcomes of pediatric appendicectomy performed by trainees versus trained surgeons. Of 2,086 articles screened, 5 retrospective non-randomized comparative studies reporting on 10,019 participants were analyzed. There was no difference in overall complications (OR 0.92; 95% CI 0.76, 1.12; P = 0.42), major complications [Clavien-Dindo (CD) III/IV] (OR 1.18; 95% CI 0.71, 1.97; P = 0.52), minor complications (CD I/II) (OR 1.13; 95% CI 0.57, 2.27; P = 0.72), post-op ileus (OR 0.74; 95% CI 0.10, 5.26; P = 0.76), wound infections (OR 0.87; 95% CI 0.62, 1.21; P = 0.41), abscess formation (OR 0.58; 95% CI 0.28, 1.22; P = 0.15), operation times [Mean Difference (MD) 2.31 min; 95% CI - 4.94, 9.56; P = 0.53] and reoperation rate (OR 1.22; 95% CI 0.23, 6.42; P = 0.81). Trainees had fewer conversions to open appendicectomy (OR 0.14; 95% CI 0.02, 0.88; P = 0.04). Appendicectomy performed on pediatric patients by trainees did not compromise patient safety.

The early outcomes of complex abdominal wall reconstruction with polyvinylidene (PVDF) mesh in the setting of active infection: a prospective series. Langenbecks Arch Surg 2022; 407:3089-3099. [PMID: 35906299 DOI: 10.1007/s00423-022-02625-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Accepted: 07/22/2022] [Indexed: 11/27/2022]
Abstract
PURPOSE The use of synthetic mesh to repair infected abdominal wall defects remains controversial. Polyvinylidene fluoride (PVDF) mesh was introduced in 2002 as an alternative to polypropylene, with the advantages of improved biostability, lowered bending stiffness, and minimum tissue response. This study aimed to evaluate the short-term outcomes of using PVDF mesh to treat infected abdominal wall defects in the elective setting. METHODS This prospective clinical trial started in 2016 and was designed to evaluate the short- and mid-term outcomes of 38 patients submitted to abdominal wall reconstruction in the setting of active mesh infection and/or enteric fistulas (AI) when compared to a group of 38 patients submitted to clean ventral hernia repairs (CC). Patients were submitted to single-staged repairs, using onlay PVDF mesh (DynaMesh®-CICAT) reinforcement to treat their defects. RESULTS Groups had comparable demographic characteristics. The AI group had more previous abdominal operations and required a longer operative and anesthesia time. At 30 days, surgical site occurrences were observed in 16 (42.1%) AI vs. 17 (44.7%) CC, p = 0.817; surgical site infection occurred in 4 (10.5%) AI vs. 6 (15.8%) CC, p = 0.497; and a higher number of procedural interventions were required in the CC group, 15.8 AI vs. 28.9% CC, p = 0.169. Both groups did not have chronic infections at 1 year of follow-up, and one hernia recurrence was observed in the AI group. CONCLUSIONS The use of PVDF mesh in the infected setting presented favorable results with a low incidence of wound infection.

Abstract
Objective: Appendicectomy remains of the most common emergency operations in the United Kingdom. The exact etiologies of appendicitis remain unclear with only potential causes suggested in the literature. Social deprivation and ethnicity have both been demonstrated to influence outcomes following many operations. There are currently no studies evaluating their roles with regards to severity and outcomes following appendicectomy.
Material and Methods: Demographic data were retrieved from health records for adult patients who underwent appendicectomy between 2010-2016 within a single NHS trust. To measure social deprivation, Indices of Multiple Deprivation (IMD) rankings were used. Histology reports were reviewed and diagnosis classified into predefined categories: non-inflamed appendix, uncomplicated appendicitis, complicated appendicitis and gangrenous appendicitis.
Results: Three thousand four hundred and forty-four patients were identified. Mean age was 37.8 years (range 73 years). Using a generalized linear model, South Asian ethnicity specifically was found to be independently predictive of increased length of stay following appendicectomy (p< 0.001). Amongst South Asian patients, social deprivation was found to be further predictive of longer hospital stay (p= 0.005). Deprivation was found to be a predictor of complicated appendicitis but not of gangrenous appendicitis (p= 0.01). Male gender and age were also independent predictors of positive histology for appendicitis (p< 0.001 and p= 0.021 respectively).
Conclusion: This study is the first to report an independent association between South Asian ethnicity and increased length of stay for patients undergoing appendicectomy in a single NHS trust. The associations reported in this study may be a result of differences in the pathophysiology of acute appendicitis or represent inequalities in healthcare provision across ethnic and socioeconomic groups.

Abstract
BACKGROUND Appendicitis accounts for the most frequent surgical emergencies in childhood. The guidance from the Royal College of Surgeons and poor post operative outcomes in surgical patients during the pandemic, it would be expected that only children who had clinical signs of appendicitis and were unwell, would have undergone surgery. Hence, the negative appendicectomy rate during the pandemic should have decreased.The aim of this retrospective study was to assess the rate of negative appendicectomy amongst children <16 years of age during the first wave of the pandemic, from the announcement of the lockdown and determine if there was a true difference by comparing the rate with the same time period in 2019. MATERIAL AND METHODS Data of all children aged<16 years who were operated for appendicitis between 23/3/2020 and 30/06/2020 was collected retrospectively and compared with that of children operated during the same time period in 2019 for the rate of negative appendicectomy.Data were analysed using the two-tailed t-test for continuous data and χ2 or Fishers exact tests for categorical data with p value of <0.05 considered significant. RESULTS Twenty three paediatric patients presenting with acute appendicitis underwent appendicectomy during the COVID-19 pandemic and 35 patients during 2019.Overall 17.39% patients underwent laparoscopic appendicectomy in 2020 while 54.29% in 2019. The negative appendicectomy rate was zero during the pandemic while it was 17.14% in 2019. There was no difference in the median length of hospital stay during the two time periods. There was no significant difference in complication or re-admission rate. CONCLUSION This study has the lowest reported incidence of negative appendicectomy rate during the pandemic following wider use of pre operative imaging and early senior involvement in decision making. The increased number of complicated appendicitis during the pandemic did not translate to worse clinical outcomes.

Abstract
Background Traditionally, uncomplicated acute appendicitis (AA) has been treated with appendectomy. However, the surgical alternatives might carry out significant complications, impaired quality of life, and higher costs than nonoperative treatment. Consequently, it is necessary to evaluate the different therapeutic alternatives' cost-effectiveness in patients diagnosed with uncomplicated appendicitis. Methods We performed a model-based cost-effectiveness analysis comparing nonoperative management (NOM) with open appendectomy (OA) and laparoscopic appendectomy (LA) in patients otherwise healthy adults aged 18–60 years with a diagnosis of uncomplicated AA from the payer´s perspective at the secondary and tertiary health care level. The time horizon was 5 years. A discount rate of 5% was applied to both costs and outcomes. The health outcomes were quality-adjusted life years (QALYs). Costs were identified, quantified, and valorized from a payer perspective; therefore, only direct health costs were included. An incremental analysis was estimated to determine the incremental cost-effectiveness ratio (ICER). In addition, the net monetary benefit (NMB) was calculated for each alternative using a willingness to pay lower than one gross domestic product. A deterministic and probabilistic sensitivity analysis was performed.

A deterministic and probabilistic sensitivity analysis was performed. Results LA presents a lower cost ($363 ± 35) than OA ($384 ± 41) and NOM ($392 ± 44). NOM exhibited higher QALYs (3.3332 ± 0.0276) in contrast with LA (3.3310 ± 0.057) and OA (3.3261 ± 0.0707). LA dominated the OA. The ICER between LA and NOM was $24,000/QALY. LA has a 52% probability of generating the highest NMB versus its counterparts, followed by NOM (30%) and OA (18%). There is a probability of 0.69 that laparoscopy generates more significant benefit than medical management. The mean value of that incremental NMB would be $93.7 per patient. Conclusions LA is a cost-effectiveness alternative in the management of patients with uncomplicated AA. Besides, LA has a high probability of producing more significant monetary benefits than NOM and OA from the payer’s perspective in the Colombian health system.

Abstract
Introduction. Prophylactic surgery before spaceflight may eliminate the risk of appendicitis and cholecystitis in astronauts on deep space missions. However, even minimally invasive surgery increases the risk of small bowel obstruction (SBO). Probabilistic risk assessment (PRA) is a method that can be used to estimate the benefits and risks of prophylactic surgery. Methods. Risks of appendicitis and cholecystitis during a 2.5-year Mars mission are compared to the risk of SBO after laparoscopic removal of the appendix, gallbladder, or both. A PRA model using Monte Carlo methodology was used to forecast the risks. Results. Prophylactic appendectomy and cholecystectomy combined, conferred an increased probability of medical evacuation (pEVAC) due to SBO as compared to the no surgery group. A slightly higher probability for the loss of crew life (pLOCL) was found in the no surgery group when compared to the cases in which either prophylactic appendectomy alone, or appendectomy plus cholecystectomy are performed. Discussion. The need for medical evacuation can be viewed as a potential risk for death in the context of a space mission where evacuation is not possible. Because of the higher pEVAC due to SBO and relatively small benefit in the reduction of pLOCL in the prophylactic surgery groups, this analysis does not support the prophylactic removal of appendix and/or gallbladder for spaceflight. Future advances in surgical or medical technique or mission medical capabilities may change these results. This work demonstrates the utility of PRA in providing quantitative answers to "what if" questions where limited information is available.

Abstract
Background: Acute appendicitis (AA) is one of the most common causes of abdominal pain requiring surgical intervention. Approximately 20% of AA cases are characterized by complications such as gangrene, abscesses, perforation, or diffuse peritonitis, which increase patients' morbidity and mortality. Diagnosis of AA can be difficult, and evaluation of clinical signs, laboratory index and imaging should be part of the management of patients with suspicion of AA.Methods: This consensus statement was written in relation to the most recent evidence for diagnosis and treatment of AA, performing a literature review on the most largely adopted scientific sources. The members of the SPIGC (Italian Polispecialistic Society of Young Surgeons) worked jointly to draft it. The recommendations were defined and graded based on the current levels of evidence and in accordance with the criteria adopted by the American College of Chest Physicians (CHEST) for the strength of the recommendations.Results: Fever and migratory pain tend to be present in patients with suspicion of AA. Laboratory and radiological examinations are commonly employed in the clinical practice, but today also scoring systems based on clinical signs and laboratory data have slowly been adopted for diagnostic purpose. The clinical presentation of AA in children, pregnant and elderly patients can be unusual, leading to more difficult and delayed diagnosis. Surgery is the best option in case of complicated AA, whereas it is not mandatory in case of uncomplicated AA. Laparoscopic surgical treatment is feasible and recommended. Postoperative antibiotic treatment is recommended only in patients with complicated AA.

Abstract
BACKGROUND Incidental appendectomy can be defined as the removal of a clinically normal appendix during another surgical procedure unrelated to appendicitis or other appendicular diseases.
AIM To compare the demographic, biochemical, and histopathological features of the patients who underwent incidental and standard appendectomy.
METHODS The demographic, biochemical, and histopathological data of 72 patients (Incidental App group) who underwent incidental appendectomy during living donor hepatectomy at our Liver Transplant Center between June 2009 and December 2016 were compared with data of 288 patients (Acute App group) who underwent appendectomy for presumed acute appendicitis. The Incidental App group was matched at random in a 1:4 ratio with the Acute App group in the same time frame. Appendectomy specimens of both groups were re-evaluated by two experienced pathologists.
RESULTS Statistically significant differences were found between groups in terms of age (P = 0.044), white blood cell count (P < 0.001), neutrophil (P < 0.001), lymphocyte (P < 0.001), red cell distribution width (P = 0.036), mean corpuscular hemoglobin (P = 0.001), bilirubin (P = 0.002), appendix width (P < 0.001), and presence of acute appendicitis histopathologically (P < 0.001). However, no statistically significant differences were found between groups in terms of gender, platelet, mean platelet volume, mean corpuscular volume, platelet distribution width, appendix length. While the most common histopathological findings in the Incidental App group were normal appendix vermiformis (72.2%), fibrous obliteration (9.7%) and acute appendicitis (6.9%), the most common histopathological findings in the Acute App group were non-perforated acute appendicitis (62.8%), perforated appendicitis (16.7%), lymphoid hyperplasia (8.3%), and appendix vermiformis (6.3%).
CONCLUSION Careful inspection of the entire abdominal cavity is useful for patients undergoing major abdominal surgery such as donor hepatectomy. We think that experience is parallel to the surgeon’s foresight, and we should not hesitate to perform incidental appendectomy when necessary
