The effect of purse-string approximation versus linear approximation of ileostomy reversal wounds on morbidity rates and patient satisfaction: the 'STOMA' trial

Circular (purse-string) vs primary skin closure following stoma closure: an up-to-date systematic review and meta-analysis

BACKGROUND

Surgical site infections (SSI) are the most common complication after stoma closure. Circular skin closure (CSC) has been proposed to reduce SSI with comparable or even better outcomes than conventional primary sutures (PS). The aim of this meta-analysis is to compare circular with primary skin closure in stoma closure.

METHOD

A systematic review of the literature was performed for articles published between January 2010 and June 2023, including all randomized control trials (RCT) on wound infection of adult patients following stoma reversal. The primary outcome was 30-day SSI; secondary outcomes were operative time, length of stay, and incisional hernia.

RESULTS

Eight RCTs were identified that included a total of 606 patients undergoing stoma closure surgery. Four percent of patients in the CSC group developed SSI, compared to 27% of patients undergoing PS. The 30-day SSI rate was lower after the circular skin closure (OR 0.11, 95% CI 0.06-0.21; p < 0.00001, I2 = 0%). There was no difference in the operative time (99.2 vs 103.5 min; MD - 0.17, 95% CI - 0.37, 0.03; p = 0.10), length of stay (7.1 vs 7.7 days; MD - 0.34, 95% CI - 0.55, - 0.12; p = 0.002), and incisional hernia rate (2% vs 4%; OR 0.61, 95% CI 0.23, 1.60; p = 0.31).

CONCLUSION

CSC is associated with lower SSI rate and should be preferred to linear skin closure technique after stoma closure surgery.

Usefulness of a negative pressure wound therapy system for stoma closure

OBJECTIVE

Although wound infection rates after stoma closure have decreased, they remain high. Negative pressure wound therapy (NPWT) for stoma closure wounds can shorten healing time for many wound types. The PICO (Smith+Nephew, UK) wound dressing, a single-use NPWT system that can be used for outpatients, was introduced at the Japan Community Health Care Organization Hokkaido Hospital, Japan in November 2017. We evaluated the effectiveness of this dressing in stoma closure wounds.

METHOD

We retrospectively evaluated patients who underwent stoma closure between March 2012 and July 2021. We compared postoperative short-term outcomes (surgical site infection (SSI), number of pain medications, and postoperative hospital stay) by allocating the patients to one of two groups: purse-string closure or purse-string closure with PICO. The purse-string closure group (PC) underwent purse-string closure alone, while the other group underwent purse-string closure and PICO (PCP).

RESULTS

A total of 35 patients were evaluated; 20 in the PC group and 15 in the PCP group. No significant differences in characteristics were noted between the groups. Comparisons between stoma closure techniques revealed that the PCP group had shorter hospital stays (p=0.04), lower SSI rates (p=0.04), and less pain medication (p<0.01) than the PC group. Comparisons between SSI occurrence revealed that the group of patients with an SSI had a higher number of colostomies compared with ileostomies (37.5% versus 0%, p<0.01, respectively), used more pain medication (p<0.01), and had longer hospital stays (p=0.04) than patients who did not have an SSI.

CONCLUSION

After stoma closure, combining PICO with purse-string closure may be effective in preventing SSI and controlling postoperative pain.

Effectiveness of Subcutaneous Negative-Suction Drain on Surgical Site Infection After Ileostomy Reversal: A Propensity Score Matching Analysis

Background/Objective: Surgical site infection (SSI) is a leading common condition after ileostomy reversal (IR). However, evidence is unclear that subcutaneous negative-suction drainage (SND) reduces the incidence of SSI. This study aimed to investigate whether SND effectively reduced the incidence of SSI. Methods: We retrospectively analyzed the records of 531 patients who underwent IR at Incheon St. Mary's Hospital between June 2005 and December 2020. SND was classified into two groups based on its presence or absence. The estimated risk of SSI was calculated using the surgical risk calculator of the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP). After 1:1 propensity score matching (PSM) using the estimated risk of SSI, we analyzed the two group's postoperative outcomes, including SSI rates. Results: After PSM, there was no difference in demographics between the two groups; however, the reversal interval was longer in the SND group than in the no SND group (193.3 ± 151.6 vs. 151.5 ± 141.0 days, p = 0.005). The incidence of SSI was lower in the SND group than in the no SND group (5.2% vs. 13.0%, p = 0.013). Conclusions: SND insertion can reduce the incidence of SSI during IR. Therefore, SND insertion should be considered as a basic technique for reducing SSI after IR.

Mechanically powered negative pressure dressing reduces surgical site infection after stoma reversal

Background

The use of closed-incision negative pressure wound therapy (ci-NPWT) has been shown to reduce postoperative wound complications and surgical site infections (SSI) after stoma closures. However, use of this approach has not been widely adopted due to high cost of the devices. We present a novel approach to stoma closure in which a self-contained mechanically powered negative pressure dressing (MP-NPD) is applied to primarily closed stoma reversal wounds. We hypothesized that SSI and wound complication rates would be improved compared to traditional stoma closure methods.

Methods

This was a prospective investigator-initiated study, in which consecutive patients that underwent stoma reversal with primary stoma wound closure dressed with MP-NPD from May 2021-March 2022. 30-day outcomes from the study group, including surgical site infection, other wound complications, hospital length of stay (LOS), and readmission rates, were then reported.

Results

Forty-six patients undergoing local ileostomy or colostomy closure were identified for the study group. Patient demographics and surgical variables were reported. One (2.2 %) patient in the study cohort developed superficial SSI within 30 days of their surgery. Post-op LOS in the study group versus was 4.1 days.

Conclusion

Intestinal stoma reversal wounds closed primarily and dressed with the MP-NPD dressings had very low stoma site SSI rates. These results are promising as they pertain to the use of MP-NPD in stoma reversal procedures, however further large prospective RCTs with a matched control group could help better corroborate these findings.

Purse-string versus linear closure of the skin wound following stoma reversal: A meta-analysis with RCT and systematic review

BACKGROUND

Linear closure (LC) following stoma reversal is associated with a high risk of surgical site infection (SSI). Purse-string closure and LC were both positive for the closure of the skin wound following stoma reversal, and it was not yet possible to distinguish which one was more beneficial to the patient's prognosis.

METHODS

We conducted a search in Embase, PubMed, Web of Science, and Cochrane Library and conducted a randomized controlled experiment from the inception of each database to July 2024. Among them, the SSI within 30 days, operation time, hospitalization time, incisional hernia, and wound healing time were all outcome indicators.

RESULTS

Eleven studies were included in this meta-analysis (506 patients in the purse-string closure group and 489 patients in the LC group). The pooled data showed that the SSI rate was significantly lower in the purse-string closure group than in the LC group (odds ratio, 0.15; 95% confidence interval, 0.09-0.24; P < .00001; I2 = 0%). The differences in operative time, hospitalization time, incision hernia, and wound healing time were not statistically significant.

CONCLUSION

Overall, purse-string closure had a significantly lower SSI rate following stoma reversal than LC.

The Outcome of Purse-string Versus Conventional Wound Closure Techniques in Patients Undergoing Stoma Reversal: A Randomized Controlled Trial

BACKGROUND

Patients undergoing stoma reversal may experience surgical site infections and poor scarring. A purse-string closure approach may lower the incidence of surgical site infections due to its inherent ability to drain wound exudates. This study compared the frequency of surgical site infections and the cosmetic outlook of the scar among patients undergoing stoma reversal with linear and purse-string skin closure techniques.

SETTING AND DURATION

Department of Pediatric Surgery, University of Child Health Sciences Lahore with a duration of one year (June 2021 to June 2022).

METHODS

This randomized controlled trial (TCTR20210417001) was conducted with IRB approval. A total of 124 patients undergoing stoma reversal were randomly assigned to two groups (62 in each): Group A received conventional linear skin closure, while Group B received purse-string wound closure. The study evaluated surgical site infection, cosmetic outcome, and length of stay.

RESULTS

Both groups had similar age, gender ratio, indication for surgery, and length of stay. The purse-string group had a significantly lower incidence of SSI (38.7 % vs. 14.5 %; p = 0.002) and better scar quality (Manchester scar scale showed 'good' scar quality in 63 % of patients vs. 22.6 % in the linear closure group, p-value <0.0001).

CONCLUSION

The purse-string technique for skin closure resulted in fewer surgical site infections and improved scar appearance.

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.

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.

Surgical Site Infection After Stoma Reversal: A Comparison Between Linear and Purse-String Closure

INTRODUCTION

Intestinal stomas are utilized for both benign and malignant conditions of the intestine to mitigate the risk of anastomotic leakage and re-exploration. However, stomas are associated with various complications, such as stoma necrosis, peri-stomal irritation, parastomal hernia, bleeding, bowel obstruction, and electrolyte abnormalities. Surgical site infection (SSI) is a significant source of morbidity following stoma reversal, leading to increased patient morbidity. The conventional method of stoma reversal involves closing the skin with non-absorbable sutures in a linear fashion, which is known as linear skin closure (LSC). Recently, a new method of skin closure using purse-string approximation (PSA) has been advocated, which allows healing by secondary intention. The rationale for this study is to compare the SSI associated with LSC and PSA after stoma reversal.

OBJECTIVE

This study aims to compare the frequency of SSI between LSC and PSA in stoma reversal.

MATERIALS AND METHODS

The study was conducted at the Department of General Surgery, Shifa International Hospitals Ltd. (SIH), Islamabad, Pakistan. The study is a randomized controlled clinical trial carried out between the 14th of March 2021 and the 22nd of November 2022. The sampling technique was non-probability consecutive random sampling. The sample size was calculated using the WHO sample size calculator by using the hypothesis test for two population proportions. The minimum sample size in each group was 40 patients. The total sample size was 80 patients.

RESULTS

The overall frequency of SSI in all the patients was 18/80 (22.5%). The frequency of SSI in Group 1 (LSC) was 6/40 (15.0%), and in Group 2 (PSA), it was 12/40 (30.0%). The frequency of SSI in Group 2 (PSA) was twice as high as in Group 1 (LSC); however, the p-value was calculated to be 0.108. Therefore, this difference was statistically insignificant.

CONCLUSIONS

While PSA has exhibited promise in reducing SSI rates and enhancing aesthetic outcomes and patient satisfaction, there is still enough data favoring LSC. Moreover, insufficient data is available for our population to make a definitive statement. Consequently, further research on this topic is warranted, preferably involving larger sample sizes and multicenter randomized controlled trials, to establish which technique is superior in SSI reduction.

Risk factors for surgical site infections and trends in skin closure technique after diverting loop ileostomy reversal: A multi-institutional analysis

BACKGROUND

Surgical site infections (SSIs) are one of the most common complications following diverting loop ileostomy (DLI) closures. This study assesses SSIs after DLI closure and the temporal trends in skin closure technique.

METHODS

A retrospective review was conducted using the American College of Surgeons National Surgical Quality Improvement Program database for adult patients who underwent a DLI closure between 2012 and 2021 across a multistate health system. Skin closure technique was categorized as primary, primary ​+ ​drain, or purse-string closure. The primary outcome was SSI at the former DLI site.

RESULTS

A SSI was diagnosed in 5.7% of patients; 6.9% for primary closure, 5.7% for primary closure ​+ ​drain, and 2.7% for purse-string closure (p ​= ​0.25). A diagnosis of Crohn's disease, diverticular disease, and increasing operative time were significant risk factors for SSIs. There was a positive trend in the use of purse-string closure over time (p ​< ​0.0001).

CONCLUSIONS

This study identified a low SSI rate after DLI closure which did not vary significantly based on skin closure technique. Utilization of purse-string closure increased over time.

Wound Infection After Ileostomy Closure: An Interim Analysis of a Prospective Randomized Study Comparing Primary Versus Circumferential Subcuticular Closure Techniques

Background: Circumferential subcuticular wound approximation (CSWA) of round shaped skin wounds after ileostomy take down is believed to lower the rates of surgical site infection (SSI). We performed this randomized trial to compare the rates of SSI and other short-term outcomes among primary linear skin closure (PC) and CSWA groups of patients. Patients and Methods: All patients undergoing ileostomy reversal during the study period were randomly assigned to either PC or CSWA. The primary outcome was the incidence of SSI as assessed by ASEPSIS scoring system. The secondary outcomes included healing time, length of post-operative hospital stay, and patients' satisfaction regarding cosmetic outcome, expectations, pain, time of healing, wound care, and activity on a five-point Likert scale. Results: Thirty-one patients (PC = 15; CSWA = 16) underwent ileostomy reversal during the study period. There was no SSI in the PC group whereas three patients developed SSI in the CSWA group but the result was not statistically significant (p = 0.23). The scores for time of healing (p < 0.001), wound care (p = 0.007), and activity (p < 0.001) were significantly better for PC compared with CSWA whereas there was no significant difference in the scores for cosmetic outcome, expectations, and pain. Healing time was shorter in the PC group (6.7 vs. 34.2 days; p < 0.001) whereas the post-operative length of stay was comparable (6.3 vs. 7 days; p = 0.27). Conclusions: Although there was no difference in the incidence of SSI among the two groups, the PC group fared better in terms of mean time to healing and requirement of wound care.

A comparison of surgical site infections in children after stoma reversal between purse-string and linear closure

BACKGROUND

To reduce the surgical site infections (SSI), the purse-string closure technique has been widely performed and has also been recommended in adult stoma reversal. However, for children, some debate still exists. This study aims to compare the SSI rates in children between the purse-string and the linear for the skin closure of stoma reversal.

METHODS

The data were collected from pediatric patients, who had undergone either purse-string or linear closure for elective surgery of stoma reversal from two university hospitals between January 2016 and December 2019.

RESULTS

The purse-string and linear closure had been performed on 31 and 45 patients, respectively. At 30 days after surgery, three patients in the purse-string closure group had developed SSI compared to 14 patients in the linear closure group (9.7 vs. 31.1%, p = 0.028). Furthermore, there had been no significant difference in the overall post-operative complications. In multivariate analysis, the SSI had been significantly lower in patients with purse-string closure (OR 0.21, 95% CI 0.05-0.86, p = 0.029).

CONCLUSION

By employing the purse-string closure technique for skin closure of stoma reversal, there had been a significantly lower SSI rate compared to linear closure with no difference in the length of hospital stay.

Negative-pressure wound therapy after stoma reversal in colorectal surgery: a randomized controlled trial

Background

Stoma-reversal surgery is associated with high postoperative morbidity, including wound complications and surgical-site infections (SSIs). This study aims to assess whether the application of negative-pressure wound therapy (NPWT) can improve wound healing compared with conventional wound dressing.

Methods

This was a single-centre, superiority, open-label, parallel, individually randomized controlled trial. Patients undergoing stoma reversal were randomized (1 : 1) to receive NPWT or conventional wound dressing. The primary endpoint of the study was the rate of wound complications and SSIs after stoma closure. The secondary endpoints were postoperative wound pain, rate of wound healing after 30 days from stoma closure, and wound aesthetic satisfaction.

Results

Between June 2019 and January 2021, 50 patients were allocated to the NPWT group (all received NPWT, 49 were analysed); 50 patients were allocated to the conventional wound dressing group (48 received the treatment, 45 were analysed). No significant difference was found in wound-complication rate (10 per cent NPWT versus 16 per cent controls; odds ratio 0.61 (95 per cent c.i. 0.18 to 2.10), P = 0.542) and incisional SSI rate (8 per cent NPWT versus 7 per cent controls; odds ratio 1.24 (95 per cent c.i. 0.26 to 5.99), P = 1.000). The NPWT group showed less pain, higher aesthetic satisfaction (P < 0.0001), and a higher proportion of wound healing (92 versus 78 per cent; P = 0.081) compared with the control group.

Conclusion

NPWT does not reduce the incidence of SSI after stoma-reversal surgery compared with conventional wound dressing. However, NPWT improved the healing of uninfected wounds, reduced wound pain and led to better aesthetic outcomes.

Prophylactic negative-pressure wound therapy after ileostomy reversal for the prevention of wound healing complications in colorectal cancer patients: a randomized controlled trial

Background

The aim of this study was to assess the usefulness of protective negative-pressure wound therapy (NPWT) in the reduction of wound healing complications (WHC) and surgical site infections (SSI) after diverting ileostomy closure in patients who underwent surgery for colorectal cancer.

Methods

In this prospective randomized clinical trial in a tertiary academic surgical center, patients who had colorectal cancer surgery with protective loop ileostomy and were scheduled to undergo ileostomy closure with primary wound closure from January 2016 to December 2018 were randomized to be treated with or without NPWT. The primary endpoint was the incidence of WHC. Secondary endpoints were incidence of SSI, length of postoperative hospital stay (LOS), and length of complete wound healing (CWH) time.

Results

We enrolled 35 patients NPWT (24 males [68.6%]; mean age 61.6 ± 11.3 years), with NPWT and 36 patients (20 males [55.6%]; mean age 62.4 ± 11.3 years) with only primary wound closure (control group). WHC was observed in 11 patients (30.6%) in the control group and 3 (8.57%) in the NPWT group (p = 0.020). Patients in the NPWT group had a significantly lower incidence of SSI (2 [5.71%] vs. 8 [22.2%] in the control group; p = 0.046) as well as significantly shorter median CWH (7 [7–7] days vs. 7 [7–15.5] days, p = 0.030). There was no difference in median LOS between groups (3 [2.5–5] days in the control group vs. 4 [2–4] days in the NPWT group; p = 0.072).

Conclusions

Prophylactic postoperative NPWT after diverting ileostomy closure in colorectal cancer patients reduces the incidence of WRC and SSI.

Gunsight Procedure Versus the Purse-String Procedure for Closing Wounds After Stoma Reversal: A Multicenter Prospective Randomized Trial

BACKGROUND

Stoma reversal is associated with a high risk of wound infection. The gunsight and purse-string closure techniques are both effective alternatives for stoma reversal, but comparative studies are lacking.

OBJECTIVE

The purpose of this study was to compare the gunsight procedure with the purse-string closure technique when closing wounds after loop stoma reversal.

DESIGN

This was a nonblinded, multicenter prospective randomized study (clinicaltrials.gov No. NCT02053948).

SETTINGS

The study was conducted at a general surgery unit of 7 tertiary academic medical centers.

PATIENTS

A total of 143 patients undergoing loop stoma reversal were included in the study (72 in the gunsight group and 71 in the purse-string group) between November 2013 and December 2017.

INTERVENTION

Patients were randomly assigned to undergo either gunsight or purse-string closure procedure.

MAIN OUTCOME MEASURES

Primary outcome was wound healing time. Secondary outcomes were the incidence of surgical site infection, morbidity, and patient satisfaction.

RESULTS

No differences were found between the 2 groups in terms of surgical site infection, intraoperative blood loss, and postoperative hospital stay. The gunsight procedure had a shorter wound healing time compared with the purse-string procedure (17 vs 25 d; p < 0.001). A patient satisfaction questionnaire showed that the gunsight group had a higher score level of patient satisfaction with respect to wound healing time (p < 0.001) and total patient satisfaction score (p = 0.01) than the purse-string group.

LIMITATIONS

Treatment teams were not blinded, and there was operator dependence of techniques.

CONCLUSIONS

The gunsight and purse-string techniques are effective procedures for stoma reversal and both have a low incidence of surgical site infection. The gunsight technique is associated with shorter wound healing time, higher levels of patient satisfaction with regard to healing time, and overall final score and is recommended as the closure technique of choice.

El procedimiento de gunsight tuvo un tiempo más corto en la cicatrización de la herida, en comparación con el procedimiento de jareta (17 días frente a 25 días, p <0,001). Un cuestionario de satisfacción del paciente, mostró que el grupo de gunsight tenía una puntuación más alta en relación al tiempo de cicatrización de la herida (p <0.001) y la puntuación total en satisfacción del paciente (p = 0.01), que en el grupo de jareta.Los equipos de tratamiento quirúrgico, no fueron cegados y hubo en los cirujanos, dependencia en las técnicas.Las técnicas de gunsight y de jareta son procedimientos efectivos para la reversión de estoma y ambas tienen una baja incidencia de infección en el sitio quirúrgico. La técnica de gunsight está asociada con un tiempo más corto en cicatrización de heridas, mejores niveles en satisfacción del tiempo de cicatrización y en la puntuación general final. Se recomienda como la técnica de cierre de elección. Consulte Video Resumen en http://links.lww.com/DCR/B319. (Traducción-Dr Fidel Ruiz Healy).

A combination of subcuticular sutures and subcutaneous closed-suction drainage reduces the risk of incisional surgical site infection in loop ileostomy closure

PURPOSE

The purpose of this study was to evaluate the effectiveness of a wound closure method using a combination of subcuticular sutures and subcutaneous closed-suction drainage (SS closure) for preventing incisional surgical site infection (SSI) in loop ileostomy closure.

METHODS

A total of 178 consecutive patients who underwent loop ileostomy closure at Nara Medical University Hospital between 2004 and 2018 were retrospectively assessed. The patients were divided into 2 groups: the conventional skin closure (CC) group from 2004 to 2009 (75 patients) and the SS closure (SS) group from 2010 to 2018 (103 patients). The incidence of incisional SSI was compared between the two groups, and the factors associated with incisional SSI were examined by univariate and multivariate analyses.

RESULTS

Incisional SSI occurred in 7 cases (9.3%) in the CC group but was significantly reduced to only 1 case (0.9%) in the SS group (p = 0.034). In the univariate analysis, the hemoglobin levels, serum creatinine levels, and SS closure were associated with incisional SSI. SS closure was the only independent preventive factor for incisional SSI according to the multivariate analysis (hazard ratio = 0.24, p = 0.011).

CONCLUSION

The combination of subcuticular sutures and subcutaneous closed-suction drainage may be a promising way of preventing incisional SSI in loop ileostomy closure.

Evaluation of negative-pressure wound therapy for surgical site infections after ileostomy closure in colorectal cancer patients: a prospective multicenter study

PURPOSE

Surgical site infection (SSI) occurs at a high rate after ileostomy closure. The effect of preventive negative-pressure wound therapy (NPWT) on SSI development in closed wounds remains controversial. We conducted a prospective multicenter study to evaluate the usefulness of preventive NPWT for SSI after ileostomy closure.

METHODS

From January 2018 to November 2018, 50 patients who underwent closure of ileostomy created after surgery for colorectal cancer participated in this study. An NPWT device was applied to each wound immediately after surgery and then treatment was continued for 3 days. The primary endpoint was 30-day SSI, and the secondary endpoints were the incidence of seroma, hematoma, and adverse events related to NPWT.

RESULTS

No patients developed SSI, seroma, or hematoma. Adverse events that may have been causally linked with NPWT were contact dermatitis in two patients and wound pain in one patient, and there were no cases of discontinuation or decompression of NPWT.

CONCLUSION

The use of NPWT following ileostomy closure may be useful for reducing the development of SSI in colorectal cancer patients. This is a prospective multicenter pilot study and we are planning a comparative study based on these successful results.

Risk Factors for Adverse Outcomes after Ostomy Reversal in Infants Less than Six Months Old

The purpose of this study was to determine risk factors for 30-day complications, reoperation, and readmission after ostomy reversal in infants less than six months old. Infants aged two weeks to six months who underwent ostomy reversal were identified in the 2012 to 2016 ACS NSQIP Pediatric database. Demographics, comorbidities, and 30-day outcomes were assessed. Multivariable logistic regression was used to estimate the independent effects of clinical variables on risk of 30-day complications, reoperation, and readmission. Among 1021 infants, 163 (16%) suffered a 30-day complication. SSIs were the most common complication (5.7%), followed by unplanned reintubation (5.2%) and bleeding (3%). Mortality was 0.4 per cent. Dependence on nutritional support and hematologic disorders were independently associated with postoperative complications. Forty-five children (4.4%) required reoperation and 22 (2.2%) were readmitted for conditions related to the procedure. Younger age and preoperative dependence on oxygen or nutritional support were associated with increased length of stay. SSI, unplanned reintubation, and bleeding are the most frequent complications after ostomy takedown in infants less than six months old. Attention to risk factors predisposing to these complications, including dependence on nutritional support and hematologic disorders, may contribute to improved surgical outcomes.

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

BACKGROUND

Compromised wound healing following stoma reversal is a frequent problem. The use of negative suction drainage for reduction of complications remains controversial.

METHODS

The patient database of our center was reviewed for patients with ileostomy reversal between 2007 and 2017. Risk factors for wound complications were analyzed using multivariate regression analysis. Systematic review and meta-analysis was performed. Ultimately, results of this study were integrated into meta-analysis to assess the effect of drainage placement on wound healing.

RESULTS

In our institutional analysis, a total of 406 patients with ileostomy reversal were included (n = 240 (59.1%) with drainage vs. n = 166 (40.8%) without drainage). In multivariate analysis, body mass index (BMI) was a risk factor for wound complications (odds ratio (95% CI) 1.06 (1.02-1.12)). Patients with drainage needed significantly fewer interventions than those without drainage (17.1% vs. 28.9%, p = 0.005). Placement of drainage significantly reduced the risk of wound complications even in the group with elevated BMI (odds ratio (95% CI) 0.462 (0.28-0.76), p = 0.003). Meta-analysis identified 6 studies with a total of 1180 patients eligible for further analysis (2 prospectively randomized trials; 4 retrospective cohort studies). Overall analysis revealed a significantly beneficial effect of wound drainage following ileostomy reversal (RR (95% CI) 0.47 (0.34, 0.66); p < 0.0001).

CONCLUSION

In our institutional analysis as well as meta-analysis, the use of subcutaneous suction drains was beneficial for prevention of wound healing complications following ostomy reversal. Drainage placement is especially valuable in high-risk situations such as in obese patients.

Quality of life following ostomy reversal with purse-string vs linear skin closure: a systematic review

BACKGROUND

The importance of the defunctioning stoma on minimizing anastomotic leak in colorectal surgery is well established. However, a defunctioning stoma can substantially impact on quality of life (QoL). Circumferential purse-string approximation (PSA) and linear skin closure (LSC) are the most commonly performed surgical technique for reversal of stoma. The aim of this review was to systemically review and meta-analyze available randomized controlled trials (RCTs) comparing PSA and LSC.

METHODS

An electronic systematic search using MEDLINE databases (PubMed, EMBASE, and Web of Science) of RCTs comparing PSA and LSC was performed. Eight RCTs totalling 647 patients met the inclusion criteria and were included in this meta-analysis.

RESULTS

Patient's satisfaction is significantly lower in PSA group during the first postoperative week, but it sharply improves afterwards and no difference were noted at 1 and 6 months between the two groups. Relative risk (RR) of developing a SSI is significantly lower in PSA compared to LSC group (RR 0.16 95% CI 0.09; 0.30; p = 0.0001), whereas incisional hernia (RR 0.53 95% CI 0.08; 3.53; p = 0.512), operative time (MD - 0.06 95% CI - 0.30; 0.17; p = 0.593), and hospital stay (MD - 0.09 (95% CI - 0.29-0.11; p = 0.401) remain similar.

DISCUSSION

QoL was similar in both patients groups after the first postoperative week. PSA significantly reduced SSI rate. No difference was observed in incisional hernia rate, operative time, or length of hospital stay.

Purse-string skin closure versus linear skin closure techniques in stoma closure: a comprehensive meta-analysis with trial sequential analysis of randomised trials

OBJECTIVES

To compare purse-string skin closure (PSC) and linear skin closure (LSC) techniques in patients undergoing stoma closure METHODS: We conducted a systematic review of literature and meta-analysis of outcomes according to PRISMA statement standards to compare PSC and LSC techniques in stoma closure. Trial sequential analysis (TSA) was performed to assess the possibility of type I or II error and compute the information size required for conclusive meta-analysis.

RESULTS

We identified six randomised controlled trials (RCTs) and eight observational studies, enrolling a total of 1102 patients. The included populations in the PSC and LSC groups were comparable in terms of baseline characteristics. The risk of surgical site infection (SSI) was significantly lower in the PSC group (OR 0.10; 95% CI 0.06, 0.18; P < 0.00001). There was no difference between the two groups in terms of operative time (MD 1.80; 95% CI - 1.35, 4.96; P = 0.26), anastomotic leak (OR 0.73; 95% CI 0.21, 2.48; P = 0.61), incisional hernia (OR 0.59; 95% CI 0.25, 1.37; P = 0.22), small bowel obstruction (OR 0.96, 95% CI 0.50, 1.86; P = 0.91), and length of hospital stay (MD - 0.04; 95% CI - 0.51, 0.42; P = 0.86). Patient satisfaction was higher in the PSC group. TSA showed that the risk of type 1 error was minimal and meta-analysis was conclusive.

CONCLUSIONS

PSC is associated with significantly lower risk of SSI and better patient satisfaction compared with LSC in closure of stomas and should be the closure technique of choice. The current available evidence is robust and conclusive highlighting that the results of the current study should be incorporated into clinical practice without a need for further trial data.

Does Wound Irrigation with Clorhexidine Gluconate Reduce the Surgical Site Infection Rate in Closure of Temporary Loop Ileostomy? A Prospective Clinical Study

BACKGROUND

The aim of this study was to investigate the effect of irrigating the surgical site with 0.05% chlorhexidine gluconate (CHG) on surgical site infection (SSI) in temporary loop ileostomy closure.

METHODS

In this observational cohort, patients who underwent diverting loop ileostomy and elective ileostomy closure for any reason between September 2014 and July 2016 were enrolled. Irrigation of the surgical site with 0.05% CHG or saline were compared regarding post-operative incision complications. Infection risk was estimated by the National Nosocomial Infection Surveillance System (NNIS) and Study of the Effect of Nosocomial Infection Control (SENIC) scores. Post-operative follow-up was performed by a surgeon blinded to the treatment. Diagnosis of SSI was recorded according to the Guidelines for Prevention of Surgical Site Infection. Wound healing was evaluated by the Additional treatment, Serous discharge, Erythema, Purulent exudate, Separation of the deep tissues, Isolation of bacteria, and the duration of inpatient Stay (ASEPSIS) score.

RESULTS

There were 122 patients meeting the inclusion criteria: 60 in the saline (control) and 62 in the CHG (study) group. The mean age was 56.5 ± 13.5 (standard deviation [SD]); 74 patients were male. The groups were similar regarding age, sex, indication for ileostomy, neoadjuvant therapies, and SENIC and ASEPSIS scores. The overall SSI rate was 18%: 19 patients (31.6%) in the control group and 3 (4.8%) patients in the study group (p < 0.001). The mean ASEPSIS score was higher in the control group (12.8 ± 17.7) than in the study group (3.7 ± 7.8) (p < 0.001). Patients in the control group had significantly higher rates of seroma (13.3% vs 1.6%; p = 0.014) and incision dehiscence (31.6% and 4.8%; p = 0.001). Time to healing was 9.9 ± 5.1 days in the control group and 7.3 ± 5.3 days in the study group (p = 0.007).

CONCLUSIONS

Irrigation of the incision with 0.05% CHG reduces the SSI rate compared with saline irrigation. There is a need for randomized and wider trials to clarify the effect and standards of incision irrigation.

Stomal Closure: Strategies to Prevent Incisional Hernia

Incisional hernias following ostomy reversal occur frequently. Incisional hernias at the site of a previous stoma closure can cause significant morbidity, impaired quality of life, lead to life-threatening hernia incarceration or strangulation and result in a significant financial burden on health care systems Despite this, the evidence base on the subject is limited. Many recognised risk factors for the development of incisional hernia following ostomy reversal are related to patient factors such as age, malignancy, diabetes, COPD, hypertension and obesity, and are not easily correctable. There is a limited amount of evidence to suggest that prophylactic mesh reinforcement may be of benefit to reduce the post stoma closure incisional hernia rate but a further large scale randomised controlled trial is due to report in the near future. There appears to be weak evidence to suggest that surgeons should favour circular, or "purse-string" closure of the skin following stoma closure in order to reduce the risk of SSI, which in turn may reduce incisional hernia formation. There remains the need for further evidence in relation to suture technique, skin closure techniques, mechanical bowel preparation and oral antibiotic prescription focusing on incisional hernia development as an outcome measure. Within this review, we discuss in detail the evidence base for the risk factors for the development of, and the strategies to prevent ostomy reversal site incisional hernias.
