Comparison of surgical techniques for stoma closure: A retrospective study of purse-string skin closure versus conventional skin closure following ileostomy and colostomy reversal

Early postoperative complications after transverse colostomy closure, a retrospective study

BACKGROUND

Ostomy is a common surgery usually performed to protect patients from clinical symptoms caused by distal anastomotic leakage after colorectal cancer (CRC) surgery and perforation or to relieve intestinal obstruction.

AIM

To analyze the complications after transverse colostomy closure.

METHODS

Patients who underwent transverse colostomy closure from Jan 2015 to Jan 2022 were retrospectively enrolled in a single clinical center. The differences between the complication group and the no complication group were compared. Logistic regression analyses were conducted to find independent factors for overall complications or incision infection.

RESULTS

A total of 102 patients who underwent transverse colostomy closure were enrolled in the current study. Seventy (68.6%) patients underwent transverse colostomy because of CRC related causes. Postoperative complications occurred in 30 (29.4%) patients and the most frequent complication occurring after transverse colostomy closure was incision infection (46.7%). The complication group had longer hospital stays (P < 0.01). However, no potential risk factors were identified for overall complications and incision infection.

CONCLUSION

The most frequent complication occurring after transverse colostomy closure surgery in our center was incision infection. The operation time, interval from transverse colostomy to reversal, and method of anastomosis might have no impact on the postoperative complications. Surgeons should pay more attention to aseptic techniques.

Effect of closed incision negative pressure wound therapy on incidence rate of surgical site infection after stoma reversal: a pilot study

Introduction

The stoma reversal (SR) procedure is associated with a relatively high risk of perioperative complications with surgical site infection (SSI) as the most common. Recently closed incision negative pressure wound therapy (ciNPWT) was applied widely to prevent SSI.

Aim

To investigate the efficiency of ciNPWT in terms of the incidence rate of SSI after SR surgery.

Material and methods

As an exploratory observational cohort study patients were treated either with ciNPWT (n = 15) or standard sterile dressing (SSD) (n = 15). CiNPWT was applied every 3 days whereas SSD was changed every day. Clinical evaluation for SSI signs, C-reactive protein level and pain assessment using the visual analogue scale (VAS) were analyzed.

Results

The incidence rate of SSI was in 13% (2/15) in the ciNPWT group and 26% (4/15) in the SSD group (p = 0.651, OR = 0.44, 95% CI: 0.03–3.73). All patients in the SSD group who developed SSI presented both local and generalized signs of infection. Pain-VAS levels assessed on the 1^st (MdnciNPWT = 4, MdnSSD = 5, p = 0.027, W = 51.5) and 3^rd postoperative day (MdnciNPWT = 2, MdnSSD = 4, p = 0.014, W = 45.5) were significantly lower in the ciNPWT group than in the SSD group.

Conclusions

CiNPWT seems not to have a benefit to reduce SSI after the SR procedure. Further investigation is needed to establish firmly the benefit of using ciNPWT in this group of patients.

Evidence-based adoption of purse-string skin closure for stoma wounds

Background

Opinion is divided on the optimal technique of skin closure after stoma reversal as most conventional techniques compromise either on speed/neatness of wound apposition or on the incidence of surgical site infection (SSI). Evidence suggests that purse-string skin closure (PSSC) may achieve both objectives. This study aims to compare conventional primary closure (PC) with PSSC to determine the efficacious technique for stoma wound closure.

Methods

Patients undergoing stoma reversal between April 2015 and September 2017 were prospectively studied. Patients were divided into two groups based on the technique of skin closure (PC or PSSC). The following parameters were assessed: SSI, hospital stay, additional outpatient visit, wound healing time and patient satisfaction based on a standardised questionnaire.

Results

Forty one patients underwent stoma reversal (20 PSSC vs 21 PC). Wound infection, need for wound care, length of hospital stay, healing time and scar size were significantly less, whereas average patient wound satisfaction scores were significantly more in the PSSC group.

Conclusion

Purse-string skin closure (PSSC) proves efficacious and hence merits adoption as the technique of choice for closure of stoma wounds.

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.

Incidence of and risk factors for stoma-site incisional herniation after reversal

Background

Stoma reversal is often considered a straightforward procedure with low short‐term complication rates. The aim of this study was to determine the rate of incisional hernia following stoma reversal and identify risk factors for its development.

Methods

This was an observational study of consecutive patients who underwent stoma reversal between 2009 and 2015 at a teaching hospital. Patients followed for at least 12 months were eligible. The primary outcome was the development of incisional hernia at the previous stoma site. Independent risk factors were assessed using multivariable logistic regression analysis.

Results

After a median follow‐up of 24 (range 12–89) months, 110 of 318 included patients (34·6 per cent) developed an incisional hernia at the previous stoma site. In 85 (77·3 per cent) the hernia was symptomatic, and 72 patients (65·5 per cent) underwent surgical correction. Higher BMI (odds ratio (OR) 1·12, 95 per cent c.i. 1·04 to 1·21), stoma prolapse (OR 3·27, 1·04 to 10·27), parastomal hernia (OR 5·08, 1·30 to 19·85) and hypertension (OR 2·52, 1·14 to 5·54) were identified as independent risk factors for the development of incisional hernia at the previous stoma site. In addition, the risk of incisional hernia was greater in patients with underlying malignant disease who had undergone a colostomy than in those who had had an ileostomy (OR 5·05, 2·28 to 11·23).

Conclusion

Incisional hernia of the previous stoma site was common and frequently required surgical correction. Higher BMI, reversal of colostomy in patients with an underlying malignancy, stoma prolapse, parastomal hernia and hypertension were identified as independent risk factors.

Temporary closure of colostomy with suture before colostomy takedown improves the postoperative outcomes

PURPOSE

Temporary loop colostomy is a common surgical procedure used to avoid complications in high-risk distal anastomosis as well as pelvic inflammation. Issues regarding postoperative outcomes of colostomy takedown have been widely discussed in the literature, wound infection especially. Temporary closure of colostomy with suture before takedown was adopted in our study, which provided excellent traction to aid mobilization of stomy and avoided stool spillage to downgrade the wound classification to "clean contamination." We aimed to determine the effects of the procedure on postoperative outcomes.

METHODS

This was a prospective case-control study at a single tertiary medical center. Patients presenting for elective colostomy takedown were included. Allis clamp (n = 50) or silk suture (n = 60) was applied to mobilize the colostomy, and results were compared. Operative time and wound infection rate were measured as primary postoperative outcomes. Univariate and multivariate analyses were used to demonstrate the association between the two groups and outcomes.

RESULTS

In univariate analyses, significantly shorter operative time (median = 57 min, p = 0.003) and lower postoperative wound infection rate (3%, p = 0.03) were noted in the group receiving silk suture. Multivariate analyses results showed that silk suture was significantly associated with both operative time (B = - 8.5, p = 0.01) and wound infection (odds ratio = 0.18, p = 0.04).

CONCLUSION

With the advantage of enhancing traction and decreasing contamination, the temporary closure of colostomy with suture improved takedown outcomes, including a shorter operative time and lower wound infection rate.

Early closure of defunctioning stoma increases complications related to stoma closure after concurrent chemoradiotherapy and low anterior resection in patients with rectal cancer

Background

After a low anterior resection, creating a defunctioning stoma is vital for securing the anastomosis in low-lying rectal cancer patients receiving concurrent chemoradiotherapy. Although it decreases the complication and reoperation rates associated with anastomotic leakage, the complications that arise before and after stoma closure should be carefully evaluated and managed.

Methods

This study enrolled 95 rectal cancer patients who received neoadjuvant concurrent chemoradiotherapy and low anterior resection with anastomosis of the bowel between July 2010 and November 2012. A defunctioning stoma was created in 63 patients during low anterior resection and in another three patients after anastomotic leakage.

Results

The total complication rate from stoma creation to closure was 36.4%. Ileostomy led to greater renal insufficiency than colostomy did and significantly increased the readmission rate (all p < 0.05). The complication rate related to stoma closure was 36.0%. Patients with ileostomy had an increased risk of developing complications (p = 0.017), and early closure of the defunctioning stoma yielded a higher incidence of morbidity (p = 0.006). Multivariate analysis revealed that a time to closure of ≤109 days was an independent risk factor for developing complications (p = 0.007).

Conclusions

The optimal timing of stoma reversal is at least 109 days after stoma construction in rectal cancer patients receiving concurrent chemoradiotherapy and low anterior resection.

Identifying Patients Eligible for a Short Hospital Stay After Stoma Closure

INTRODUCTION

The implementation of enhanced recovery programmes after elective colorectal surgery has dramatically reduced the length of stay. The objective of this study was to assess the selection of good candidates for short post-operative stay (GCSS) in the context of stoma closure.

METHODS

Between January 2011 and December 2014, 222 patients were included in the present retrospective, single-center study. The primary endpoint was the proportion of GCSS. We also identified factors associated with GCSS status and built a predictive score.

RESULTS

The study population was predominantly male (n = 122, 55%). 60% of the patients had undergone ileostomy and 85% had undergone hand-sewn anastomosis. The postoperative ileus rate was 5% and the readmission rate was 3.5%. 41% (n = 92) of the study population were considered to be GCSS. In a multivariate analysis, age under 50 (odds ratio (OR) [95% confidence interval (CI)] = 2.8 [1.2-5.6], p = 0.008), the absence of vascular comorbidities (OR [95%CI] = 3.2 [1.3-12.3]; p = 0.006) and stapled anastomosis (OR: 4.2, 95%CI: 1.1-17.3, p = 0.03) were associated with GCSS status. Predictive scores of 0, 1, 2, and 3 were associated with GCSS rates of 20%, 18%, 44%, and 62%, respectively (p < 0.001).

CONCLUSION

In the context of stoma closure, 41% of patients were GCSS.
