Meta-analysis and single-center experience on the protective effect of negative suction drains on wound healing after stoma 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.

Purse-string skin closure versus linear skin closure in people undergoing stoma reversal

BACKGROUND

Stoma reversal is associated with a relatively high risk of surgical site infection (SSI), occurring in up to 40% of cases. This may be explained by the presence of microorganisms around the stoma site, and possible contamination with the intestinal contents during the open-end manipulation of the bowel, making the stoma closure site a clean-contaminated wound. The conventional technique for stoma reversal is linear skin closure (LSC). The purse-string skin closure (PSSC) technique (circumferential skin approximation) creates a small opening in the centre of the wound, enabling free drainage of contaminants and serous fluid. This could decrease the risk of SSI compared with LSC.

OBJECTIVES

To assess the effects of purse-string skin closure compared with linear skin closure in people undergoing stoma reversal.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, two other databases, and three trials registers on 21 December 2022. We also checked references, searched for citations, and contacted study authors to identify additional studies.

SELECTION CRITERIA

We included all randomised controlled trials (RCTs) comparing PSSC and LSC techniques in people undergoing closure of stoma (loop ileostomy, end ileostomy, loop colostomy, or end colostomy) created for any indication.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected eligible studies, extracted data, evaluated the methodological quality of the included studies, and conducted the analyses. The most clinically relevant outcomes were SSI, participant satisfaction, incisional hernia, and operative time. We calculated odds ratios (ORs) for dichotomous data and mean differences (MDs) for continuous data, each with its corresponding 95% confidence interval (CI). We used the GRADE approach to rate the certainty of the evidence.

MAIN RESULTS

Nine RCTs involving 757 participants were eligible for inclusion. Eight studies recruited only adults (aged 18 years and older), and one study included people aged 12 years and older. The participants underwent elective reversal of either ileostomy (82%) or colostomy (18%). We considered all studies at high risk of performance and detection bias (lack of blinding) and four studies at unclear risk of selection bias related to random sequence generation. PSSC compared with LSC likely reduces the risk of SSI (OR 0.17, 95% CI 0.09 to 0.29; I2 = 0%; 9 studies, 757 participants; moderate-certainty evidence). The anticipated absolute risk of SSI is 52 per 1000 people who have PSSC and 243 per 1000 people who have LSC. The likelihood of being very satisfied or satisfied with stoma closure may be higher amongst people who have PSSC compared with people who have LSC (100% vs 89%; OR 20.11, 95% CI 1.09 to 369.88; 2 studies, 122 participants; low-certainty evidence). The results of the analysis suggest that PSSC compared with LSC may have little or no effect on the risk of incisional hernia (OR 0.51, 95% CI 0.07 to 3.70; I2 = 49%; 4 studies, 297 participants; very low-certainty evidence) and operative time (MD -2.67 minutes, 95% CI -8.56 to 3.22; I2 = 65%; 6 studies, 460 participants; very low-certainty evidence).

AUTHORS' CONCLUSIONS

PSSC compared with LSC likely reduces the risk of SSI in people undergoing reversal of stoma. People who have PSSC may be more satisfied with the result compared with people who have LSC. There may be little or no difference between the skin closure techniques in terms of incisional hernia and operative time, though the evidence for these two outcomes is very uncertain.

Short-term outcome of diverting loop ileostomy reversals performed by residents: a retrospective cohort prognostic factor study

AIM

The reversal of diverting loop ileostomy (DLI) is one of surgical trainees' first procedures. Complications of DLI reversal can cause life-threatening complications and increase patient morbidity. This study compared DLI reversals performed by surgical trainees with those by attending surgeons.

METHOD

This retrospective cohort study was performed at a single primary care center on 300 patients undergoing DLI reversal. The primary outcome was morbidity, according to the Clavien-Dindo classification (CDC), with special attention paid to the surgeon's level of training. The secondary endpoint was postoperative intestinal motility dysfunction.

RESULTS

Surgical trainees had significantly longer operation times (p < 0.001) than attending surgeons. Univariate analyses revealed no influence on the level of training for postoperative morbidity. First bowel movement later than 3 days after surgery was a significant risk factor for CDC [Formula: see text] 3 (OR, 4.348; 96% CI, 1670-11.321; p = 0.003). Independent risk factors for surgical site infections (SSIs) were an elevated BMI (OR, 1.162; 95% CI, 1.043-1.1294; p = 0.007) and a delayed bowel movement (OR, 3.973; 95% CI, 1.300-12.138; p = 0.015). For postoperative intestinal motility dysfunction, an independent risk factor was a primary malignant disease (OR, 1.980; 95% CI, 1.120-3.500; p = 0.019), and side-to-side stapled anastomosis was a protective factor (OR, 0.337; 95% CI 0.155-0.733; p = 0.006).

CONCLUSION

Even though surgical trainees needed significantly more time to perform the surgery, the level of surgical training was not a risk factor for increased postoperative morbidity. Instead, delayed first bowel movement was predictive of SSI.

[Nursing interventions in stoma reversal: an integrative reviewIntervenções de enfermagem na inversão do estoma intestinal: uma revisão integrativa]

Introduction

Intestinal stomas have a significant impact on people's quality of life. However, these should be reversed after gastrointestinal transit has been restored or the initial inflammatory response has gone. In addition, patients may refuse to reverse them due to a lack of information and guidance from healthcare professionals. Therefore, it is important to identify nursing interventions in caring for patients with stoma reversal.

Materials and Methods

An integrative literature review was conducted in WOS, PubMed, Scopus, SciELO and Cochrane databases published between 2015 and 2020. 36 articles were selected based on inclusion and exclusion criteria with their methodological analysis.

Results

The following nursing interventions were identified: preoperative assessment, bowel preparation and follow-up of comorbidities in the preoperative period; prophylaxis, skin preparation, surgical technique and abdominal wall closure in the intraoperative period; surgical wound care, quality of life and education in the postoperative period.

Discussion

It is essential to reflect on reversal time, surgical technique and the importance of nursing interventions.

Conclusions

Nursing plays an important role in stoma reversal not only because of physical care and education provided, but also the interventions applicable to social and emotional contexts affecting the patient's lifestyle.

New Scoring System for Predicting the Risk of Surgical Site Infections Following Stoma Reversal

BACKGROUND

Surgical site infections (SSI) are one of the most frequent complications following stoma reversal (SR-SSI) and lead to multiple problems such as decreased mobility of the patients or increased hospital costs. Several risk factors for SR-SSI have been reported, but there are no risk scoring systems for predicting SR-SSI. The current study aimed to analyze the risk factors for SR-SSI and develop a scoring system.

MATERIALS AND METHODS

Multivariate analysis of risk factors for SR-SSI was performed in patients who underwent elective SR and were followed-up during the first month after surgery. A logistic regression model was used to identify risk factors and construct a predictive score.

RESULTS

Of the 182 patients, 53 (29.1%) developed SSI. In multivariate analysis, three variables as preoperative risk factors were associated with increased SR-SSI incidence: subcutaneous fat thickness (≥ 20 mm) (odds ratio [OR]: 8.46 [95% confidence interval (CI): 3.45-20.7], P <0.001), period from stoma creation (≤ 20 weeks) (OR: 2.88 [95% CI: 1.14-7.28], P = 0.025), and SSI after the primary operation (OR: 3.06 [95% CI: 1.19-7.90], P = 0.021). Each of these variables contributed 2,1, and 1 points to the risk score, respectively. The SR-SSI rate was 2.9%, 20.3%, 34.2%, 54.5%, and 81.8% for the scores of 0,1,2,3, and 4 points, respectively. The area under the receiver operating characteristic curve was 0.773 (95% CI: 0.703-0.844).

CONCLUSIONS

A simple clinical scoring system based on three preoperative variables may be useful in predicting the risk of SR-SSI.

2D vs 3D laparoscopic right colectomy: A propensity score-matching comparison of personal experience with systematic review and meta-analysis

BACKGROUND

The benefits of laparoscopic approach for right colectomy have been well established. However, the technical difficulty to construct the intra-corporeal anastomosis is still cumbersome.

AIM

To analyze the results of 3D and 2D laparoscopic right colectomy and to compare it to the published series through a systematic review and meta-analysis.

METHODS

A retrospective study with propensity score matching analysis of patients undergoing laparoscopic right colectomy at Umbria2 Hospitals from January 2014 to March 2020 was performed. A systematic review was accomplished comparing 2D and 3D right colectomy.

RESULTS

In the personal series 47 patients of the 2D group were matched to 47 patients of the 3D group. The 3D group showed a favorable trend in terms of mean operative time (170.7 ± 32.9 min vs 183.8 ± 35.4 min; P = 0.053) and a significant lower anastomotic time (16.9 ± 2.3 min vs 19.6 ± 2.9 min, P < 0.001). The complete mesocolic excision (CME) subgroups analysis showed a shorter anastomotic time (16.5 ± 1.8 min vs 19.9 ± 3.0 min; P < 0.001) and operative time (175.0 ± 38.5 min vs 193.7 ± 37.1 min; P = 0.063) in the 3D group. Six studies and our series were included in the meta-analysis with 551 patients (2D group: 291; 3D group: 260).The pooled analysis demonstrated a significant difference in favour of the 3D group regarding the operative time (P < 0.001) and the anastomotic time (P < 0.001) while no differences were identified between groups in terms of blood loss (P = 0.827), LNH yield (P = 0.243), time to first flatus (P = 0.333), postoperative complications (P = 0.718) and length of stay (P = 0.835).

CONCLUSION

The meta-analysis results showed that 3D laparoscopic right colectomy shortens operative and anastomotic time without affecting the standard lymphadenectomy. In our series, the advantage of the 3D system becomes evident when CME and/or more complex associated procedure are requested significantly reducing both the total operative and the anastomotic time.
