Risk factors for surgical site infection after stoma closure comparison between pursestring wound closure and conventional linear wound closure: Propensity score matching analysis

Comparison of purse-string technique vs linear suture for skin closure after ileostomy reversal. A randomized controlled trial

BACKGROUND

Protective stoma after rectal surgery has been associated with important complications. The most common is surgical site infection (SSI) high rates after stoma reversal reported in literature. Our study compared the rate of SSI of two skin closure techniques, linear closure, and purse string closure.

METHODS

We carried out a single center, prospective, randomized controlled trial in the Department of Colorectal Surgery of Fondazione Policlinico Campus Bio-Medico of Rome between January 2018 through December 2021, to compare LC vs PS closure of ileostomy sites.

RESULTS

A total of 117 patients (53.84% male) with a mean age of 65.68 ± 14.33 years were finally evaluated in the study. 58 patients were included in the PS group and 59 patients in the LC one. There was a marked difference in the SSI rate between the two arms of the study: 3 of 58 patients in the purse-string arm versus 11 of 59 in the control arm (p = 0.043). The outcome of cosmesis was also higher in PS, with a statistical significance (mean ± DS 4,01 ± 0,73 for PS group vs mean ± DS 2,38 ± 0,72 for LC group, p < 0,001).

CONCLUSION

Our study demonstrated that the PS technique had a significantly lower incidence of stoma site SSI compared with LC technique. Our findings are in line with other randomized studies and suggest that PS closure could be considered as standard of care for wound closure after ileostomy reversal.

Clinical Benefits of Reducing Dead Space Using a Closed Suction Drain and Subcutaneous Large-bite Buried Suture Technique to Prevent Superficial Surgical-site Infections Following Primary Closure of a Diverting Stoma

Objectives

Surgical-site infections (SSIs) are the most common complication after stoma closure. We propose a new method for wound closure using the subcutaneous large-bite buried suture (SLBS) technique and a closed suction drain (CSD). In this study, we aimed to investigate the efficacy of a combination of the SLBS technique and a CSD to prevent superficial SSIs following stoma closure.

Methods

We retrospectively analyzed patients who underwent stoma closure between January 2019 and July 2022. Primary closure of the stomal site was performed using the SLBS technique and a CSD for wound closure. The CSD was placed until postoperative day 7. The occurrence of superficial postoperative SSIs was also evaluated.

Results

In total, 67 patients were included in the study. Within 30 days postoperatively, nine patients (13%) developed superficial SSIs. Considering the type of stoma, only 1 (2%) of 45 patients with ileostomy showed superficial SSIs, whereas 8 (36%) of 22 patients with colostomy showed superficial SSIs. Univariate analysis of the risk factors associated with the occurrence of superficial SSIs revealed that colostomy (p < 0.001) and hand-sewn anastomosis were significant risk factors (p = 0.019). Multivariate analysis of the risk factors associated with the occurrence of superficial SSIs revealed that colostomy was significant risk factor (p = 0.003).

Conclusions

This new method of stoma closure is feasible for preventing superficial SSIs, especially in ileostomy closure.

Fighting postsurgical infection after myelomeningocele repair with medical honey (Medihoney): a case report

Surgical site infection (SSI) prolongs the treatment period, delays wound healing, increases antibiotic consumption, and leads to patient death in complicated cases. This case was a 10-day female infant born at 37-week- and 6-day of gestational age with a birth weight of 3700 g and Apgar 5/8 by emergency cesarean section due to spina bifida cystica with myelomeningocele (MMC). She was admitted to the neonatal intensive care unit (NICU) because of respiratory distress and hypotonic lower extremities on June 2, 2022. A cardiovascular and neurosurgery consult was okay for reconstructive surgery, and she had MMC repair surgery by a plastic surgeon on June 5, 2022. The surgical site was infected, and SSI had no improvement, despite regularly receiving wet and Vaseline gauze dressing and intravenous antibiotic therapy. We started the treatment using Medihoney™, honey antibacterial wound dressing, on SSI once a day for 2 weeks, then once every other day for the next 6 weeks. Her SSI was cured entirely after 2 months, and she was discharged from our wound treatment team in satisfactory general condition. Clinicians and wound care management teams could use honey antibacterial wound gel to treat SSI, particularly in newborns with weakened immune systems after spinal birth defects repair.

Risk factor for the development of surgical site infection following ileostomy reversal: a single-center report

PURPOSE

Postoperative surgical site infection (SSI) is not uncommon in patients with ileostomy reversal. The appropriate index to predict the postoperative SSI in these individuals remains unclear. The aim of this study is to evaluate the risk factor for SSI after ileostomy reversal.

METHODS

A consecutive cohort of 201 patients who underwent elective ileostomy reversal between January 2015 and January 2020 were retrospectively analyzed. Patients were divided into two groups: SSI group and non-SSI group. Univariate and multivariate analyses were conducted to identify risk factors for postoperative SSI.

RESULTS

Postoperative SSI occurred in 37 (18.4%) patients. Compared with the non-SSI group, patients in SSI group had higher incidence of nutrition risk (56.77% vs 39.02%, P = 0.049), higher C-reactive protein (CRP) level (10.81 ± 16.49 vs 4.86 ± 4.14 mg/L, P < 0.001), and longer postoperative hospital stay (13.08 ± 3.71 vs 7.47 ± 2.38 days, P < 0.001). By analyzing the receiver-operating characteristic (ROC) curve, CRP have the value in predicting the occurrence of SSI. The areas under the ROC curves of CRP for SSI was 0.671 (95% confidence interval 0.568-0.774, P = 0.001) with an optimal diagnostic cut-off value of 8.0 mg/L. By the univariate and multivariate analyses, preoperative C-reactive protein (CRP) ≥ 8 mg/L(P < 0.001) and conventional linear closure method (P = 0.004) were independent risk factors for postoperative SSI.

CONCLUSIONS

Preoperative CRP levels can be served as a predictive index for postoperative SSI after stoma reversal. Purse-string closure technique is the treatment of choice to minimize stoma site SSI in patients with stoma reversal.

Comparison of two-stage and three-stage surgery for obstructing left-sided colon cancer

BACKGROUND

Whether the timing of stoma reversal after emergency diversion for obstructive left-sided colon cancer affects patient outcomes is unknown. Our study compared the short- and long-term outcomes of two- and three-stage operations for obstructive left-sided colon cancer.

METHODS

Patients with obstructive left-sided colon cancer who underwent staged resection at a referral hospital between January 2002 and December 2015 were retrospectively identified. Patient demographics and outcomes were analysed and compared between the two groups. Statistical significance was set as p < 0.05.

RESULTS

A total of 191 patients were reviewed. The overall complication rate was higher for two-stage surgery than for three-stage surgery (57.1% versus 36.0%, p < 0.01). Surgical site infection and/or wound dehiscence were the most common complications. Other complications, including anastomotic leakage, ileus, and bowel obstruction, were not significantly different between the two groups. The five-year overall survival and disease-free survival in stage II and III patients were comparable.

CONCLUSION

Among patients with obstructive left-sided colon cancer who underwent staged resection, two-stage surgery was associated with a higher complication rate, especially for surgical site infection and/or wound dehiscence, which could be managed by local treatment. The timing of stoma reversal was not associated with survival differences in patients with stage II and III disease. However, issues such as the location of the tumour and diverting stoma, along with the need to resect other upper abdominal organs, should all be considered when deciding between two- and three-stage surgeries.

Treating surgical site infection by honey antibacterial wound dressing in a neonate: a case report

Surgical site infection (SSI) increases length of treatment, delays wound healing, increases antibiotic use and causes patient death in severe cases. This case was a boy aged 38 weeks and 4 days with a birthweight of 2100 g, a height of 42 cm and a head circumference of 32 cm. Twelve days after birth, he was admitted to hospital where a surgeon removed a sacrococcygeal teratoma. The surgical site became infected, and the infection failed to improve despite him receiving routine normal saline dressings twice a day and intravenous antibiotic therapy. The authors started treatment using an antibacterial wound dressing containing honey (Medihoney) on the SSI twice a day for a month. The infant's SSI was wholly healed after 3 months, and he was discharged from the wound treatment team in good general condition. This case shows that SSIs can be treated with honey-containing antibacterial wound gel, especially in infants who have weaker immune systems.

Negative Pressure Wound Therapy for Closed Laparotomy Incisions in General and Colorectal Surgery: A Systematic Review and Meta-analysis

Importance

Surgical site infections (SSIs) are common after laparotomy wounds and are associated with a significant economic burden. The use of negative pressure wound therapy (NPWT) has recently been broadened to closed surgical incisions.

Objective

To evaluate the association of prophylactic NPWT with SSI rates in closed laparotomy incisions performed for general and colorectal surgery in elective and emergency settings.

Data Sources

The PubMed, Embase, Cochrane Central Register of Controlled Trials, and Google Scholar databases were searched without language restrictions for relevant articles from inception until December 2017. The latest search was performed on December 31, 2017. The bibliographies of retrieved studies were further screened for potential additional studies.

Study Selection

Randomized clinical trials and nonrandomized studies were included. Unpublished reports were excluded, as were studies that examined NPWT (or standard nonpressure) dressings only without a comparator group. Studies that evaluated the use of NPWT in open abdominal incisions were also excluded. Disagreement was resolved by discussion, and if the question remained unsettled, the opinion of the senior author was sought. A total of 198 citations were identified, and 189 were excluded.

Data Extraction and Synthesis

This meta-analysis was conducted according to PRISMA guidelines. Data were independently extracted by 2 authors. A random-effects model was used for statistical analysis.

Main Outcomes and Measures

The primary outcome measure was SSI, and secondary outcomes included seroma and wound dehiscence rates. These outcomes were chosen before data collection.

Results

Nine unique studies (3 randomized trials and 2 prospective and 4 retrospective studies) capturing 1266 unique patients were included. Of these, 1187 patients with 1189 incisions were included in the final analysis (52.3% male among 7 studies reporting data on sex; mean [SD] age, 52 [15] years among 8 studies reporting data on age). Significant clinical and methodologic heterogeneity existed among studies. On random-effects analysis, NPWT was associated with a significantly lower rate of SSI compared with standard dressings (pooled odds ratio [OR], 0.25; 95% CI, 0.12-0.52; P < .001). However, no difference in rates of seroma (pooled OR, 0.38; 95% CI, 0.12-1.23; P = .11) or wound dehiscence (pooled OR, 2.03; 95% CI, 0.61-6.78; P = .25) was found. On sensitivity analysis, focusing solely on colorectal procedures, NPWT significantly reduced SSI rates (pooled OR, 0.16; 95% CI, 0.07-0.36; P < .001).

Conclusions and Relevance

Application of NPWT on closed laparotomy wounds in general and colorectal surgery is associated with reduced SSI rates but similar rates of seroma and wound dehiscence compared with conventional nonpressure dressings.
