Effectiveness of cyanoacrylate microbial sealant in the reduction of surgical site infection in gynecologic oncology procedures: A phase III single institution prospective randomized trial

ECLAPTE: Effective Closure of LAParoTomy in Emergency-2023 World Society of Emergency Surgery guidelines for the closure of laparotomy in emergency settings

Laparotomy incisions provide easy and rapid access to the peritoneal cavity in case of emergency surgery. Incisional hernia (IH) is a late manifestation of the failure of abdominal wall closure and represents frequent complication of any abdominal incision: IHs can cause pain and discomfort to the patients but also clinical serious sequelae like bowel obstruction, incarceration, strangulation, and necessity of reoperation. Previous guidelines and indications in the literature consider elective settings and evidence about laparotomy closure in emergency settings is lacking. This paper aims to present the World Society of Emergency Surgery (WSES) project called ECLAPTE (Effective Closure of LAParoTomy in Emergency): the final manuscript includes guidelines on the closure of emergency laparotomy.

Cyanoacrylate Tissue Adhesive After Chest Tube Removal in Children

Background: After open or thoracoscopic lung biopsy, it is common to leave a chest tube as a postoperative drain that is typically removed on the first or second postoperative day. Standard technique is to apply an occlusive dressing at the site of chest tube removal using gauze and some form of tape. Methods: We reviewed the charts of children who underwent thoracoscopic lung biopsy at our institution for the past 9 years, many of whom left the operating room with a chest tube. When the tube was removed, the site was dressed, based on attending surgeon preference, with either cyanoacrylate tissue adhesive (Dermabond^®; Ethicon, Cincinnati, OH) or a standard dressing with gauze and transparent occlusive adhesive dressing. Endpoints included wound complications and need for a secondary dressing. Results: Of 134 children who underwent thoracoscopic biopsy, 71 (53%) were given a chest tube. Chest tubes were removed at bedside in standard manner after a mean of 2.5 days. In 36 (50.7%) cyanoacrylate was used and in 35 (49.3%) a standard occlusive gauze dressing was used. No patient in either group suffered a wound dehiscence or needed a rescue dressing. There were no wound-related complications or surgical site infections in either group. Conclusion: Cyanoacrylate dressings are effective for closure of chest tube drain sites and appear to be safe. They might also save patients from having to deal with a bulky bandage and the discomfort of having a strong adhesive removed from their surgical site.

Use of prophylactic closed incision negative pressure therapy is associated with reduced surgical site infections in gynecologic oncology patients undergoing laparotomy

BACKGROUND

Surgical site infection after surgery for gynecologic cancer increases morbidity. Prophylactic closed incision negative pressure therapy has shown promise in reducing infectious wound complications across many surgical disciplines.

OBJECTIVE

This study aimed to determine whether closed incision negative pressure therapy is associated with reduced surgical site infections in gynecologic oncology patients undergoing laparotomy compared with standard dressings.

STUDY DESIGN

This was a retrospective case-control study of patients undergoing laparotomy for known or suspected gynecologic cancer from Jan. 1, 2017, to Feb. 1, 2020. Patients were matched in a 1:3 ratio (closed incision negative pressure therapy to standard dressing) by body mass index, age, diabetes, bowel surgery, smoking, and steroid use. Surgical site infection was defined according to the Centers for Disease Control and Prevention. Multivariable logistic regression using backward selection was performed.

RESULTS

Of the 1223 eligible patients undergoing laparotomy, 64 (5.2%) received closed incision negative pressure therapy dressings and were matched to 192 (15.7%) controls. There were no differences in medical comorbidities (P>.05), site or stage of malignancy (P>.05), duration of surgery (P=.82), or surgical procedures (P>.05). Use of closed incision negative pressure therapy was associated with reduction in all adverse wound outcomes (20.3% vs 40.1%; P<.001). In particular, closed incision negative pressure therapy was associated with a significant reduction in both superficial incisional surgical site infections (9.4% vs 29.7%; P<.001) and deep incisional surgical site infections (0.0% vs 6.8%; P=.04). In multivariable analysis, use of closed incision negative pressure therapy was associated with significant reduction in the incidence of superficial incisional infections alone (odds ratio, 0.29; 95% confidence interval, 0.12-0.73; P=.008) and both superficial and deep incisional infections (odds ratio, 0.29; 95% confidence interval, 0.12-0.71; P=.007).

CONCLUSION

Use of prophylactic closed incision negative pressure therapy after laparotomy in gynecologic oncology patients was found to be associated with reduced superficial incisional and deep incisional infections compared with standard dressings. Furthermore, closed incision negative pressure therapy was associated with reduction in all other adverse wound outcomes. Closed incision negative pressure therapy may be considered for surgical site infection prevention in high-risk gynecologic oncology patients undergoing laparotomy.

Trends in bacterial resistance among perioperative infections in patients with primary ovarian cancer: A retrospective 20-year study at an affiliated hospital in South China

Background

We aimed to analyze the epidemiological and drug-resistance trends among bacterial cultures from perioperative infections in patients with primary ovarian cancer.

Methods

Medical and bacteriological records for patients with ovarian cancer patients who developed perioperative infections after primary cytoreductive surgery from 1999 to 2018 were reviewed retrospectively.

Results

The incidence of perioperative infections and the culture-positive percentage among patients in the first 10 years were 20.2% and 29.3%, respectively, and the equivalent rates in the second 10 years were 18.0% and 33.5%. The most commonly isolated pathogens in both year-groups were Escherichia coli and Enterococcus spp., but the respective percentages differed between the groups. Some strains of Staphylococcus aureus and Enterococcus spp. in the second 10-year group were resistant to linezolid and vancomycin, and ciprofloxacin resistance among Gram-negative bacteria isolates also increased in this group. However, resistance of Gram-negative bacteria to imipenem and meropenem was low among in both groups.

Conclusion

The pathogen distribution in perioperative infections in patients with primary ovarian cancer undergoing cytoreductive changed slightly from 1999 to 2018, and the antibiotic resistance of the main isolated pathogens increased. These results indicate the importance of periodic bacterial surveillance of surgical infections in these patients.
