Impact on infectious outcomes during laparoscopic cholecystectomy with the use of home-made vs commercial gallbladder retrieval bag: a retrospective comparative study in a high-volume center. Surg Endosc 2023; 37:587-591. [PMID: 35672501 DOI: 10.1007/s00464-022-09362-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Accepted: 05/22/2022] [Indexed: 01/18/2023]
Abstract
BACKGROUND Laparoscopic cholecystectomy (LC) is one of the most commonly performed emergency procedures, with approximately 600,000 patients undergoing the procedure every year in the United States. Although LC is associated with fewer complications when compared with open cholecystectomy, the risk for infectious complications, including surgical site infection and intra-abdominal abscess, remains a significant source of postoperative morbidity. The goal of this study is to determine whether the gallbladder retrieval technique during LC affects risk of infectious complications. METHODS AND PROCEDURES We conducted a retrospective comparative study in a minimally invasive surgery high-volume center in Bogota, Colombia. Patients who underwent LC in 2018 to 2020 were identified. The patients were divided into three groups. One group of LC performed using home-made gallbladder retrieval bag (HMGRB), and another group of LC performed using commercial gallbladder retrieval bag (CGRB). The primary outcomes were infectious complications of superficial site infection and intra-abdominal abscess. RESULTS A total of 68 (7.58%) patients underwent LC using an HMGRB, and 828 (92.41%) using a CGRB. There was no significant difference in preoperative sepsis, or sex distribution between patient groups. Using t test, we found differences on age distribution among groups (p < 0.01), surgical times (p < 0.01), and length of stay (p = 0.01). When using Chi square, we found differences in Tokyo and Parkland Grading Scale severity (p < 0.01), use of postoperative antibiotics (p < 0.01), and drain use (p < 0.01). Nonetheless, there was no difference in the rate of superficial surgical site infection (p = 0.92). CONCLUSION HMGRB are not associated with increased risk of postoperative intra-abdominal abscess or superficial surgical site infection in comparison with CGRB but imply longer surgical times and length of stay. The use of HMGRB is safe, feasible, and has lower cost during LC.

Antibiotic Prophylaxis for Hepato-Biliopancreatic Surgery—A Systematic Review. Antibiotics (Basel) 2022; 11:antibiotics11020194. [PMID: 35203797 PMCID: PMC8868388 DOI: 10.3390/antibiotics11020194] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Revised: 01/01/2022] [Accepted: 01/24/2022] [Indexed: 02/04/2023] Open
Abstract
Background: Surgical site infections (SSIs) are among the most important determinants of morbidity after HBP surgery. Their frequency after HPB surgery is variable, from 1–2% after elective cholecystectomy to 25% after PD. Methods: A systematic review was performed to assess the role of antimicrobial prophylaxis (AP) in HPB elective surgery. Articles published between 2015 and 2021 were obtained; those before 2015 were not included because they antedate the WHO guidelines on SSI prevention. We conducted three different research methods for liver resection, elective cholecystectomy and pancreatic and biliary surgery regarding patients requiring preoperative biliary drainage. Results: Hepatic surgery, improvement in surgical technique and perioperative management lead to a very low SSI. One preoperative 2 g cefazolin dose may be adequate for surgical prophylaxis. From preoperative biliary drainage, we can derive that patients’ homeostasis rather than AP plays a paramount role in reducing postoperative morbidity. The time from biliary drainage could be an essential element in decision making for surgical prophylaxis. In the case of low-risk cholecystectomy, it is not easy to draw definitive conclusions about the effect of AP. Data from the literature are inconsistent, and some risk factors cannot be predicted before surgery. Conclusion: in our opinion, a strict preoperative cefazolin dose strategy can be reasonable in HBP surgery until a large-scale, multicentric RCT brings definitive conclusions.

Abstract
One of the ways to avoid infection after surgical procedures is through
antibiotic prophylaxis. This occurs in cholecystectomies with certain risk
factors for infection. However, some guidelines suggest the use of antibiotic
prophylaxis for all cholecystectomies, although current evidence does not
indicate any advantage of this practice in the absence of risk factors.

Abstract
BACKGROUND: One of the ways to avoid infection after surgical procedures is through
antibiotic prophylaxis. This occurs in cholecystectomies with certain risk
factors for infection. However, some guidelines suggest the use of
antibiotic prophylaxis for all cholecystectomies, although current evidence
does not indicate any advantage of this practice in the absence of risk
factors. AIMS: This study aims to evaluate the incidence of wound infection after elective
laparoscopic cholecystectomies and the use of antibiotic prophylaxis in
these procedures. METHODS: This is a retrospective study of 439 patients with chronic cholecystitis and
cholelithiasis, accounting for different risk factors for wound
infection. RESULTS: There were seven cases of wound infection (1.59%). No antibiotic prophylaxis
regimen significantly altered infection rates. There was a statistically
significant correlation between wound infection and male patients (p=0.013).
No other analyzed risk factor showed a statistical correlation with wound
infection. CONCLUSIONS: The nonuse of antibiotic prophylaxis and other analyzed factors did not
present a significant correlation for the increase in the occurrence of
wound infection. Studies with a larger sample and a control group without
antibiotic prophylaxis are necessary.

HPB (Oxford) 2021; 23:161-172. [PMID: 32900611 PMCID: PMC7474810 DOI: 10.1016/j.hpb.2020.08.012] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Revised: 08/16/2020] [Accepted: 08/17/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Laparoscopic cholecystectomy is a safe ambulatory procedure in appropriately selected patients; however, day case rates remain low. The objective of this systematic review and meta-analysis was to identify interventions which are effective in reducing the length of stay (LOS) or improving the day case rate for elective laparoscopic cholecystectomy. METHODS Comparative English-language studies describing perioperative interventions applicable to elective laparoscopic cholecystectomy in adult patients and their impact on LOS or day case rate were included. RESULTS Quantitative data were available for meta-analysis from 80 studies of 10,615 patients. There were an additional 17 studies included for systematic review. The included studies evaluated 14 peri-operative interventions. Implementation of a formal day case care pathway was associated with a significantly shorter LOS (MD = 24.9 h, 95% CI, 18.7-31.2, p < 0.001) and an improved day case rate (OR = 3.5; 95% CI, 1.5-8.1, p = 0.005). Use of non-steroidal anti-inflammatories, dexamethasone and prophylactic antibiotics were associated with smaller reductions in LOS. CONCLUSION Care pathway implementation demonstrated a significant impact on LOS and day case rates. A limited effect was noted for smaller independent interventions. In order to achieve optimal day case targets, a greater understanding of the effective elements of a care pathway and local barriers to implementation is required.

Use of retrieval bag in the prevention of wound infection in elective laparoscopic cholecystectomy: is it evidence-based? A meta-analysis. BMC Surg 2018; 18:102. [PMID: 30453917 PMCID: PMC6245513 DOI: 10.1186/s12893-018-0442-z] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2018] [Accepted: 11/08/2018] [Indexed: 01/29/2023] Open
Abstract
Background Surgical site infections complicate elective laparoscopic cholecystectomies in 2,4-3,2% of cases. During the operation the gallbladder is commonly extracted with a retrieval bag. We conducted a meta-analysis to clarify whether its use plays a role in preventing infections. Methods Inclusion criteria: elective cholecystectomy, details about the gallbladder extraction and data about local or systemic infection rate. Exclusion criteria: cholecystitis, jaundice, concurrent antibiotic therapy, immunosuppression, cancer. A comprehensive literature search of PubMed, Cochrane Library and MEDLINE databases was carried out independently by two researchers, according to the PRISMA guidelines and applying the GRADE approach. Terms used were (“gallbladder”AND(“speciment”OR“extraction”OR“extract”))OR(“gallbladder”OR“cholecystectomy”)AND(“bag”OR“retrieval|”OR|“endobag”OR“endocatch”). Results The comprehensive literature revealed 279 articles. The eligible studies were 2 randomized trials and a multicentre prospective study. Wound infections were documented in 14 on 334 (4,2%) patients operated using a retrieval bag versus 16 on 271 (5,9%) patients operated without the use of a retrieval bag. The statistical analysis revealed a risk ratio (RR) of 0.82 (0.41–1.63 95% CI). Concerning sensitivity analysis the estimated pooled RR ranged from 0.72 to 0.96, both not statistically significant. Harbord test did not reveal the occurrence of small-study effect (p = 0.892) and the funnel-plot showed no noteworthy pattern. Conclusions The results of this review highlight the paucity of well-designed large studies and despite limitations related to the low level of evidence, our meta-analysis showed no significant benefit of retrieval bags in reducing the infection rate after elective laparoscopic cholecystectomy. In absence of acute cholecystitis, accidental intraoperative gallbladder perforation or suspected carcinoma their use, to date, may not be mandatory, so that, further studies focusing on complex cases are needed.

Abstract
Backgrounds/Aims The role of prophylactic antibiotics for laparoscopic cholecystectomy in low-risk patients is still unclear. This study aimed to verify the conclusion of previous meta-analyses concerning the effectiveness of antibiotic prophylaxis for elective laparoscopic cholecystectomy in low-risk patients. Methods Comprehensive literature searches were performed on electric databases and manual searches. Randomized controlled trials (RCTs), prospective studies, and retrospective studies comparing antibiotic prophylaxis to placebo or no antibiotics in low-risk elective laparoscopic cholecystectomy were included. Results This study included 28 RCTs, three prospective studies, and three retrospective studies. In RCTs, prophylactic antibiotics did not prevent deep surgical site infections (SSI) (RR 1.10, 95% confidence interval [CI] [0.45–2.69], p=0.84) but reduced SSI (RR 0.70, 95% CI [0.53–0.94], p=0.02), and superficial SSI (RR 0.58, 95% CI [0.42–0.82], p=0.01). Prospective studies showed prophylactic antibiotics did not reduce superficial SSI (RR 0.35, 95% CI [0.01–8.40], p=0.52) but reduced SSI (RR 0.12, 95% CI [0.04–0.35], p=0.0001). In retrospective studies, antibiotic prophylaxis did not reduce SSI (RR 1.59, 95% CI [0.30–8.32], p=0.58). The pooled data (12121 patients) including RCTs and prospective and retrospective studies showed that prophylactic antibiotics were not effective in preventing deep SSI (RR 1.01 95% CI [0.46–2.21], p=0.98) but effective in reducing SSI (RR 0.67, 95% CI [0.51–0.88], p=0.003) and superficial SSI (RR 0.61, 95% CI [0.45–0.83], p=0.002). Conclusions The use of prophylactic antibiotics is effective for reducing the incidence of SSI and superficial SSI but is not effective for preventing deep SSI in low-risk patients who underwent elective laparoscopic cholecystectomy.

Abstract
PURPOSE The role of prophylactic antibiotics for elective laparoscopic cholecystectomy has been questioned over the last decade. Although gradually being discontinued in the adult population, the practice among pediatric surgeons remains unknown. Our aim was to investigate the use of perioperative antibiotics in children undergoing elective laparoscopic cholecystectomy (LC) for symptomatic cholelithiasis and biliary dyskinesia. METHODS We retrospectively reviewed the Pediatric Health Information System (PHIS) database for 2015 and selected all patients 18years old or younger who underwent LC for cholelithiasis (without cholecystitis) or biliary dyskinesia. Demographic and hospital data were extracted as well as antibiotics administered and surgical complications. RESULTS A total of 1112 patients from 44 hospitals were identified with a median age of 15years (IQR 13-16years). Eight out of every 10 hospitals routinely give prophylactic antibiotics in more than 50% of patients. In 37 hospitals that performed more than 5 LC per year, 19 to 100% of patients were given antibiotics. No surgical complications were identified in those who did not get antibiotics. CONCLUSION There is significant inter-hospital variation in prophylactic antibiotic administration for elective LC in children. Perioperative antibiotic administration should be tracked as a quality metric in the current push for better stewardship. LEVEL OF EVIDENCE III. TYPE OF STUDY Retrospective.

Abstract
INTRODUCTION Accidental gallbladder perforation frequently occurs during laparoscopic cholecystectomy and may increase the risk of infection. However, the necessity of antimicrobial prophylaxis for these patients is unclear. The aim of this study was to examine the clinical outcomes and necessity of antimicrobial prophylaxis after laparoscopic cholecystectomy with gallbladder perforation. METHODS One hundred patients who underwent laparoscopic cholecystectomy were divided into two groups: patients with gallbladder perforation (Group A, n = 37) and patients without perforation (Group B, n = 63). We compared the white blood cell count and C-reactive protein level the day after the operation, the complication rates of systemic inflammatory response syndrome and surgical-site infection, and postoperative hospital stay between the two groups. All patients received antimicrobial prophylaxis only once before the operation. RESULTS There were significant differences in every variable with the exception of postoperative hospital stay. Group A had a higher risk of infection, but the postoperative clinical course of Group A was not inferior to that of Group B. CONCLUSION The clinical outcomes of patients with accidental gallbladder perforation were acceptable, and the use of antimicrobial prophylaxis once before the operation was sufficient.

Abstract
Background There are limited data on risk factors for surgical site infection (SSI) after open or laparoscopic cholecystectomy. Methods A retrospective cohort of commercially insured persons aged 18–64 years was assembled using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) procedure or Current Procedural Terminology, 4th edition codes for cholecystectomy from December 31, 2004 to December 31, 2010. Complex procedures and patients (eg, cancer, end-stage renal disease) and procedures with pre-existing infection were excluded. Surgical site infections within 90 days after cholecystectomy were identified by ICD-9-CM diagnosis codes. A Cox proportional hazards model was used to identify independent risk factors for SSI. Results Surgical site infections were identified after 472 of 66566 (0.71%) cholecystectomies; incidence was higher after open (n = 51, 4.93%) versus laparoscopic procedures (n = 421, 0.64%; P < .001). Independent risk factors for SSI included male gender, preoperative chronic anemia, diabetes, drug abuse, malnutrition/weight loss, obesity, smoking-related diseases, previous Staphylococcus aureus infection, laparoscopic approach with acute cholecystitis/obstruction (hazards ratio [HR], 1.58; 95% confidence interval [CI], 1.27–1.96), open approach with (HR, 4.29; 95% CI, 2.45–7.52) or without acute cholecystitis/obstruction (HR, 4.04; 95% CI, 1.96–8.34), conversion to open approach with (HR, 4.71; 95% CI, 2.74–8.10) or without acute cholecystitis/obstruction (HR, 7.11; 95% CI, 3.87–13.08), bile duct exploration, postoperative chronic anemia, and postoperative pneumonia or urinary tract infection. Conclusions Acute cholecystitis or obstruction was associated with significantly increased risk of SSI with laparoscopic but not open cholecystectomy. The risk of SSI was similar for planned open and converted procedures. These findings suggest that stratification by operative factors is important when comparing SSI rates between facilities.
