Abstract
We performed a literature review to describe the risk of surgical-site infection (SSI) in minimally invasive surgery (MIS) compared to standard open surgery. Most studies reported decreased SSI rates among patients undergoing MIS compared to open procedures. However, many were observational studies and may have been affected by selection bias. MIS is associated with reduced risk of surgical-site infection compared to standard open surgery and should be considered when feasible.

Liu J, Wang Q. Impact of surgical site infection after open and laparoscopic surgery among paediatric appendicitis patients: A meta-analysis. Int Wound J 2024; 21:e14524. [PMID: 38084057 PMCID: PMC10961035 DOI: 10.1111/iwj.14524] [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: 11/02/2023] [Revised: 11/15/2023] [Accepted: 11/15/2023] [Indexed: 03/25/2024] Open
Abstract
Operative site wound infection is one of the most frequent infections in surgery. A variety of studies have shown that the results of laparoscopy might be superior to those of an open procedure. Nevertheless, there is still a lack of clarity as to whether there is a difference between open and laparoscopy with respect to the occurrence of wound infections in different paediatric operations. In this review, we looked at randomized, controlled studies that directly measured the rate of wound infection following an appendectomy with a laparoscope. We looked up four main databases for randomized, controlled studies that compare the treatment of paediatric appendicitis with laparoscopy. The surgeries included appendectomy. Through our search, we have determined 323 related papers and selected five qualified ones to be analysed according to the eligibility criteria. Five trials were also assessed for the quality of the documents. In the 5 trials, there were no statistically significant differences in the incidence of post-operative wound infection among the paediatric appendectomy and the open-access group (odds ratio [OR], 0.63; 95% confidence interval [CI], 0.34-1.15, p = 0.13). The four trials did not show any statistically significant difference in abdominal abscesses among the laparoscopic and open-access treatment groups (OR, 1.64; 95% CI, 0.90-3.01, p = 0.11). The four trials did not reveal any statistically significant difference in operating time (mean difference, -4.36; 95% CI, -17.31 to 8.59, p = 0.51). In light of these findings, the use of laparoscopy as compared with the open-approach approach in paediatric appendectomies is not associated with a reduction in the risk of wound infection.

Abstract
Patients with complicated appendicitis have an increased risk for postoperative infections. Potential risk factors for postoperative infections through a meta-analysis and retrospective chart review are discussed. A meta-analysis consisting of 35 studies analyzing complicated appendicitis treated with an appendectomy noting at least 1 postoperative infection was performed. A retrospective review was then conducted in patients diagnosed with complicated appendicitis after appendectomy. Of 5326 patients in total, 15.4% developed postoperative infections. Laparoscopic surgery and perioperative hyperoxygenation were found to be protective factors for the development of infection. Retrospectively, 53.2% of patients presented with complicated appendicitis. Patients with complicated appendicitis were more likely to be older in age and have an increased length of stay. Patient demographics, operative time, and comorbid status had no effect on postoperative infection or readmission rate. Physicians should strongly consider minimally invasive techniques to treat all cases of complicated appendicitis irrespective of comorbidities, age, sex, or body mass index.

Abstract
Background: We sought to understand which factors are associated with open appendectomy as final operative approach. We hypothesize that higher American Association for the Surgery of Trauma (AAST) Emergency General Surgery (EGS) grade is associated with open appendectomy. Patients and Methods: Post hoc analysis of the Eastern Association for the Surgery of Trauma (EAST) Multicenter Study of the Treatment of Appendicitis in America: Acute, Perforated and Gangrenous (MUSTANG) prospective appendicitis database was performed. All adults (age >18) undergoing appendectomy were stratified by final operative approach: laparoscopic or open appendectomy (including conversion from laparoscopic). Univariable analysis was performed to compare group characteristics and outcomes, and multivariable logistic regression was performed to identify demographic, clinical, or radiologic factors associated with open appendectomy. Results: A total of 3,019 cases were analyzed. One hundred seventy-five (5.8%) patients underwent open appendectomy, including 127 converted from laparoscopic to open. The median age was 37 (25) years and 53% were male. Compared with the laparoscopic group, open appendectomy patients had more comorbidities, higher proportion of symptoms greater than 96 hours, and higher AAST EGS grade. Moreover, on intraoperative findings, the open appendectomy group had a higher incidence of perforated and gangrenous appendicitis with purulent contamination, abscess/phlegmon, and purulent abdominal/pelvic fluid. On multivariable analysis controlling for comorbidities, clinical and imaging AAST grade, duration of symptoms, and intra-operative findings, only AAST Clinical Grade 5 appendicitis was independently associated with open appendectomy (odds ratio [OR], 5.63; 95% confidence interval [CI], 1.24-25.55; p = 0.025). Conclusions: In the setting of appendicitis, generalized peritonitis (AAST Clinical Grade 5) is independently associated with greater odds of open appendectomy.

Abstract
BACKGROUND A very short hospital length of stay following an open appendectomy in children with acute simple appendicitis has never been mentioned yet in the literature. The authors reviewed the outcome of these paediatric patients who were treated with the open technique. MATERIALS AND METHODS In this analytical cohort observational study, we retrospectively reviewed the medical records of the 115 consecutive patients who underwent open appendectomy from June 2017 to July 2021. RESULTS There were 84 patients whose appendices were inflammatory or suppurative and appendectomies were done only through McBurney's point. Of these, the average age was 9.11 ± 2.67 years. The mean length of the incision was 1.95 ± 0.48 cm. Nearly one-third (25/85) were discharged within 3 h following surgery. Of the remaining cases, nine patients were discharged within the same day. There were increased percentages of patients who were eligible for early discharge in each consecutive year. CONCLUSION The idea of immediate discharge within 3 h seems to be feasible for children with acute simple appendicitis who were treated with open appendectomy. We believe that the practice will be widely acknowledged and proceed to reduce the resources and the expenses in the hospital.

Abstract
PURPOSE This was a pilot randomised, prospective study, which aimed to determine and compare the post-operative complications of paediatric patients undergoing laparoscopic appendectomy (LA) for complicated appendicitis, with and without a peritoneal drain. METHODS Patients younger than 13 years, undergoing LA for complicated appendicitis at the Dr George Mukhari Academic Hospital (DGMAH), over a 15-month period during 2019-2020 were enrolled. Randomisation was achieved by a blocked randomisation plan. Patients were randomised in a 1:1 ratio into the "drain" (D) and "no drain" (ND) groups. RESULTS Thirty-four patients were included in this study; seventeen in each group. The complication rate was 26%. Intra-abdominal collection accounted for 89% of the complications. The complication rate in the "D" group was 18% and 35% in the "ND" group, with no statistically significant difference. Complication rates were higher (38%) in patients with generalised pus when compared to localised pus (7%), although not statistically significant. The mean theatre time, hospital stay, and duration of antibiotic use did not differ significantly between the groups. CONCLUSION From our study, the post-operative peritoneal drain did not make any statistically significant difference in patient outcome. The amount of intra-abdominal contamination is more likely to contribute in the development of complications. TRIAL REGISTRATION NUMBER SMUREC/M/15/2019: PG.

Abstract
INTRODUCTION Despite its wide acceptance, the superiority of laparoscopic versus open pediatric surgery has remained controversial. There is still a call for well-founded evidence. We reviewed the literature on studies published in the last three decades and dealing with advantages and disadvantages of laparoscopy compared to open surgery. MATERIALS AND METHODS Studies comparing laparoscopic versus open abdominal procedures in children were searched in PubMed/MEDLINE. Reports on upper and lower gastrointestinal as hepatobiliary surgery and on surgery of pancreas and spleen were included. Advantages and disadvantages of laparoscopic surgery were analyzed for different types of procedures. Complications were categorized using the Clavien-Dindo classification. RESULTS A total of 239 studies dealing with 19 types of procedures and outcomes in 929,157 patients were analyzed. We identified 26 randomized controlled trials (10.8%) and 213 comparative studies (89.2%). The most frequently reported advantage of laparoscopy was shorter hospital stay in 60.4% of studies. Longer operative time was the most frequently reported disadvantage of laparoscopy in 52.7% of studies. Clavien-Dindo grade I to III complications (mild-moderate) were less frequently identified in laparoscopic compared to open procedures (80.3% of studies). Grade-IV complications (severe) were less frequently reported after laparoscopic versus open appendectomy for perforated appendicitis and more frequently after laparoscopic Kasai's portoenterostomy. We identified a decreased frequency of reporting on advantages after laparoscopy and increased reporting on disadvantages for all surgery types over the decades. CONCLUSION Laparoscopic compared with open pediatric surgery seems to be beneficial in most types of procedures. The number of randomized controlled trials (RCTs) remains limited. However, the number of reports on disadvantages increased during the past decades.

Abstract
Surgical site infections (SSIs) are the most common healthcare-associated infections in patients undergoing surgery. Various randomised control trials (RCTs) indicate that laparoscopic procedures can be associated with better outcomes compared to open procedures. However, how open versus laparoscopic approaches compare across various paediatric procedures with respect to SSI rate remains poorly defined. In this review, we examined RCTs that directly compare SSI rates after open versus laparoscopic operations for appendicitis, gastro-esophageal reflux, inguinal hernia, and pyloric stenosis. MEDLINE, Embase, and Web of Science were searched for RCTs comparing four types of open versus laparoscopic operations in children. The operations included appendectomy, fundoplication for gastro-esophageal reflux, inguinal hernia repair, or pyloromyotomy. 364 records were identified and screened, 54 full-text articles were assessed for eligibility, and 17 RCTs were included in the analysis. SSI rate was the primary outcome. Operative time and length of stay (LOS) were the secondary outcomes. A meta-analysis was conducted using RevMan 5.4 software. Laparoscopic appendectomy had a lower SSI rate than open appendectomy (odds ratio of 2.22 [1.19, 4.15] p = 0.01). Laparoscopic fundoplication for gastro-esophageal reflux, inguinal hernia repair, or pyloromyotomy for pyloric stenosis were not associated with lower SSI rate compared to open surgery. Operative time was shorter in open fundoplication (- 71.22 min [- 89.79, - 52.65] p < 0.00001) than laparoscopic fundoplication. There was no significant difference in operative time of any of the other procedures. There was no significant difference in LOS between open and laparoscopic procedures for all types of operations analysed. Based on the findings of this review, it is recommended to utilise the laparoscopic approach over the open approach to reduce SSI risk in paediatric appendectomy.

Abstract
BackgroundIn the pediatric population, appendectomy is one of the most common emergency operations. Laparoscopic appendectomy (LA) is an accepted way of dealing with suspected uncomplicated appendicitis in children. The role of laparoscopy in appendicular lump is more controversial and remains undefined and is not well practiced in low-middle income countries. The aim of this study was to determine a better surgical treatment plan for early appendicular lump in children.MethodsThis prospective observational study was performed in Pediatric Surgery Department of Chittagong Medical College and Hospital for a period of 1 year from April 2018 to March 2019. Sixty children with appendicular lump selected consecutively as per eligibility criteria underwent either LA or open appendectomy (OA), that is, 30 children per group. They were followed up until hospital discharge to observe outcomes.ResultsThere were no differences in terms of patient’s age, sex, clinical presentation and laboratory findings between the two groups. Postoperative pain severity was significantly less in the LA group than that in the OA group (p<0.01). The incidence of wound infection was significantly lower in the LA group than that in the OA group (6.7% in LA and 46.7% in OA; p<0.01). Children in the LA group had a shorter duration of hospital stay in comparison to the OA group [median (IQR) was 8 (5.75–11.25) days and 12 (7.75–18.00) days, respectively, in LA and OA groups; p=0.01].ConclusionThe study findings suggest that LA is feasible and should replace OA in cases of early appendicular lump in children.

Abstract
AIM Perforated appendicitis has poorer clinical outcomes compared to non-perforated appendicitis. However, accurate outcome comparisons in research and clinical audits are challenged by its wide spectrum of manifestation. Previous attempts at the classification of severity have been complex and difficult to reproduce. In our study, we used another institution's (Jones et al., TX, USA) previously described simple classification system of peritoneal contamination and examined its usefulness in predicting outcomes. METHODS With ethical approval, we retrospectively reviewed the records of all paediatric patients operated at our institution for perforated appendicitis from 2016 to 2017. Patient demographics, intra-operative and histological findings, post-operative outcomes and length of stay were collected. Patients were categorised into group 1 (purulence in right lower quadrant only) and group 2 (contamination in two or more quadrants). Post-operative complications were defined as procedure-related (e.g. post-operative ileus, intra-abdominal abscess, visceral injury) and non-procedure-related (e.g. bronchospasm). Statistical analysis using χ2 tests for categorical data and Mann-Whitney U-tests for non-parametric continuous variables was performed, with a significance of P < 0.05. RESULTS There were 134 eligible patients. We excluded 19 with incomplete data, leaving 115 for analysis, of which 69 (60%) were in group 2. Those in group 2 had a longer stay (P = 0.005) and more post-operative complications (P = 0.001), particularly procedure-related events (P = 0.006). There were no differences in age (P = 0.182), gender (P = 0.876), readmission rate (P = 0.317) and non-procedure-related post-operative complications (0.152). CONCLUSION This simple classification of perforated appendicitis appears to differentiate clinical outcomes well, particularly for iatrogenic morbidity, making it useful for operative preparation and outcomes research.

Abstract
BACKGROUND The removal of the acute appendix is one of the most frequently performed surgical procedures. Open surgery associated with therapeutic efficacy has been the treatment of choice for acute appendicitis. However, in consequence of the evolution of endoscopic surgery, the operation can also be performed with minimally invasive surgery. Due to smaller incisions, the laparoscopic approach may be associated with reduced postoperative pain, reduced wound infection rate, and shorter time until return to normal activity.This is an update of the review published in 2010. OBJECTIVES To compare the effects of laparoscopic appendectomy (LA) and open appendectomy (OA) with regard to benefits and harms. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), Ovid MEDLINE and Embase (9 February 2018). We identified proposed and ongoing studies from World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP), ClinicalTrials.gov and EU Clinical Trials Register (9 February 2018). We handsearched reference lists of identified studies and the congress proceedings of endoscopic surgical societies. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing LA versus OA in adults or children. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, assessed the risk of bias, and extracted data. We performed the meta-analyses using Review Manager 5. We calculated the Peto odds ratio (OR) for very rare outcomes, and the mean difference (MD) for continuous outcomes (or standardised mean differences (SMD) if researchers used different scales such as quality of life) with 95% confidence intervals (CI). We used GRADE to rate the quality of the evidence. MAIN RESULTS We identified 85 studies involving 9765 participants. Seventy-five trials included 8520 adults and 10 trials included 1245 children. Most studies had risk of bias issues, with attrition bias being the largest source across studies due to incomplete outcome data.In adults, pain intensity on day one was reduced by 0.75 cm on a 10 cm VAS after LA (MD -0.75, 95% CI -1.04 to -0.45; 20 RCTs; 2421 participants; low-quality evidence). Wound infections were less likely after LA (Peto OR 0.42, 95% CI 0.35 to 0.51; 63 RCTs; 7612 participants; moderate-quality evidence), but the incidence of intra-abdominal abscesses was increased following LA (Peto OR 1.65, 95% CI 1.12 to 2.43; 53 RCTs; 6677 participants; moderate-quality evidence).The length of hospital stay was shortened by one day after LA (MD -0.96, 95% CI -1.23 to -0.70; 46 RCTs; 5127 participant; low-quality evidence). The time until return to normal activity occurred five days earlier after LA than after OA (MD -4.97, 95% CI -6.77 to -3.16; 17 RCTs; 1653 participants; low-quality evidence). Two studies showed better quality of life scores following LA, but used different scales, and therefore no pooled estimates were presented. One used the SF-36 questionnaire two weeks after surgery and the other used the Gastro-intestinal Quality of Life Index six weeks and six months after surgery (both low-quality evidence).In children, we found no differences in pain intensity on day one (MD -0.80, 95% CI -1.65 to 0.05; 1 RCT; 61 participants; low-quality evidence), intra-abdominal abscesses after LA (Peto OR 0.54, 95% CI 0.24 to 1.22; 9 RCTs; 1185 participants; low-quality evidence) or time until return to normal activity (MD -0.50, 95% CI -1.30 to 0.30; 1 RCT; 383 participants; moderate-quality evidence). However, wound infections were less likely after LA (Peto OR 0.25, 95% CI 0.15 to 0.42; 10 RCTs; 1245 participants; moderate-quality evidence) and the length of hospital stay was shortened by 0.8 days after LA (MD -0.81, 95% CI -1.01 to -0.62; 6 RCTs; 316 participants; low-quality evidence). Quality of life was not reported in any of the included studies. AUTHORS' CONCLUSIONS Except for a higher rate of intra-abdominal abscesses after LA in adults, LA showed advantages over OA in pain intensity on day one, wound infections, length of hospital stay and time until return to normal activity in adults. In contrast, LA showed advantages over OA in wound infections and length of hospital stay in children. Two studies reported better quality of life scores in adults. No study reported this outcome in children. However, the quality of evidence ranged from very low to moderate and some of the clinical effects of LA were small and of limited clinical relevance. Future studies with low risk of bias should investigate, in particular, the quality of life in children.
