Factors affecting closure of a temporary stoma

Closure timing of a temporary ileostomy in patients with rectal cancer undergoing anus-preserving operation: a retrospective cohort study

PURPOSE

To investigate the optimal closure time of a temporary ileostomy in patients with rectal cancer receiving anus-preserving operation.

METHODS

Patients with rectal cancer were enrolled from the Affiliated Hospital of Jiangsu University from May 2010 to June 2019. The eligible patients were grouped according to their actual ileostomy closure time after stoma creation. Outcomes were complications during stoma closure and complications within one year after stoma closure.

RESULTS

This study included 361 qualified subjects, with 108 patients in the 3-5 months group, 133 in the 5-7 months group and 120 in the ≥ 7 months group. Compared with the risk of complications during stoma closure in the 3-5 months group, that in the 5-7 months group was significantly reduced (odds ratio [OR]: 0.36, 95% confidence interval [CI] 0.13-0.99), and that in the ≥ 7 months group was significantly increased (OR: 5.88, 95% CI 2.38-14.56). In contrast to the 3-5 months group, the 5-7 months group showed a significantly decreased risk (OR: 0.21, 95% CI 0.07-0.67), and the ≥ 7 months group showed a significantly increased risk (OR: 4.21, 95% CI 1.61-11.01) of complications within 1 year after stoma closure.

CONCLUSION

5-7 months after the ileostomy is created may be the optimal time for its closure.

Racial Disparities After Stoma Construction Exist in Time to Closure After 1 Year but Not in Overall Stoma Reversal Rates

INTRODUCTION

Conflicting data exist on racial disparities in stoma reversal (SR) rates. Our aim was to investigate the role of race in SR rates, and time to closure, in a longitudinal, racially diverse database.

METHODS

All adult patients (>18 years) who received an ileostomy or colostomy from 1999 to 2016 at a single institution were identified. Primary outcomes were SR rates and time to closure. Failure to reverse and time to closure was modeled using Cox regression. Kaplan-Meier survival curves, stratified by race, were generated for time to closure and hazard ratios (HRs) calculated.

RESULTS

Of 770 patients with stomas, 65.6% of patients underwent SR; 76.6% were white and 23.4% were black. On adjusted analysis, race did not predict overall SR rates or time to closure if performed less than 1 year. Instead, significant predictors for failure in SR included age, insurance status, end colostomy/ileostomy, and loop colostomy (p < 0.05). Predictors of delay in time to closure included insurance, end colostomy/ileostomy, and loop colostomy (p < 0.05). In patients who underwent reversal after 1 year, black race was an independent predictor of time to closure (HR 0.21, 95% CI 0.07-0.63, p < 0.05).

CONCLUSION

SR rates were equal between black and white patients. Disparities in time to closure existed only for black patients if reversed more than 1 year after index stoma construction. While equitable outcomes were achieved for most patients, further investigation is necessary to understand stoma disparities after 1 year.

Effectiveness between early and late temporary ileostomy closure in patients with rectal cancer: A prospective study

A temporary stoma is often used in rectal cancer surgery to protect a distal anastomosis, which remains a major concern after rectal cancer surgery, particularly after low anterior resection. The temporary stoma is scheduled for closure. However, the optimal time of closure of the protecting stoma remains unclear because of sparse studies and data. We aimed to detect the efficacy between early and late temporary ileostomy closure in patients with rectal cancer during or after neoadjuvant chemoradiotherapy. We conducted a prospective, 2-group design between early and late ileostomy closure group in patients after rectal cancer surgery with temporary stoma. Participants were recruited in a teaching hospital in Guangzhou, China. A total of 161 patients confirmed diagnosis of rectal cancer underwent curative surgery and temporary ileostomy. Participants with temporary ileostomy received closure surgery after 1 (early) or 6 (late) months were assessed by clinical parameters and quality of life. Patients in late closure group received more adjuvant chemotherapy cycles but with comparable incidence of stoma closure-related complications and length of hospital stay compared to early closure group. Participants in late closure group with standardized postoperative chemotherapy might have a better prognosis compared with those in early closure group. An increased emphasis should be given to choose the optimal closure time of patients with rectal cancer having temporary ileostomy. Colorectal nurses could provide support to physician for observation of prognosis of different closure time.

Is it safe the reversal of a diverting stoma during adjuvant chemotherapy in elderly rectal cancer patients?

INTRODUCTION

The aim of this study was to investigate the clinical outcomes between 2 groups of elderly rectal cancer patients according to the time duration after which their diverting stoma can be reversed.

METHODS

We recruited 124 patients who were ≥65 years old and had undergone diverting stoma after rectal cancer surgery. In Group 1, the reversal of the stoma was predominantly performed after the sixth adjuvant chemotherapy. In Group 2, the reversal was predominantly performed after the third adjuvant chemotherapy.

RESULTS

The mean duration for which patients had a stoma was 28.6 ± 9.9 weeks in Group 1 and 17.1 ± 7.4 weeks in Group 2. The interval between stoma formation and stoma formation-related complications was slightly longer in Group 1 than in Group 2 (13.5 ± 9.7 vs. 8.0 ± 4.9 weeks, p = 0.075). There were 16 stoma-related complications in Group 1 (23.2%) and 10 in Group 2 (18.2%) (p = 0.516). There were 6 stoma closure-related complications in Group 1 (8.8%) and 6 in Group 2 (10.9%) (p = 0.766).

DISCUSSION

This study shows that stoma closure during adjuvant chemotherapy is no more harmful than stoma closure after termination of adjuvant chemotherapy.

CONCLUSION

It may be possible to limit the duration of diverting stoma following rectal cancer surgery, even if patients are elderly and undergoing adjuvant chemotherapy.
