Studies indicate that a temporary ileostomy can be safely reversed early and no later than 12 weeks after it was fashioned. However, the latency between stoma construction and closure is often significantly longer and may be as long as 6 months, and it is not uncommon (9-57%) for stomas not to be taken down at all.[1-4] Reasons for failure to close a stoma include advanced patient age, low body mass index, presence of a terminal stoma, and neoadjuvant radiotherapy.[2, 5, 6] Other reasons include progressive malignancy, initial surgery with complications, and, in particular, anastomotic failure.[1, 7]
There are hardly any recommendations in the literature for ideal timing of ileostomy reversal, and management varies greatly from hospital to hospital.[8]
In 2021, a study was published with a high level of evidence that investigated postoperative complications after early closure of a diverting stoma ("early closure" [EC] ≤ 6 weeks vs. standard closure [SC] > 6 weeks) following rectal resection with unremarkable postoperative course.[9] Early closure was not associated with a higher rate of postoperative complications. However, the condition for early reversal is that patients do not have to undergo postoperative or adjuvant chemotherapy after initial surgery (rectal resection with diverting stoma).
In terms of anastomotic technique, manual and stapled suture lines are equivalent with respect to morbidity. Stapled anastomoses speed up the operating time and reduce the postoperative obstruction rate [10], but they are also incur higher costs.[11] When comparing manually sutured end-to-end anastomoses with side-to-end anastomoses, the former increases morbidity and length of stay in hospital.[12]
The body of studies on skin closure after ileostomy takedown shows a significant benefit for purse-string over linear skin closure in terms of septic wound complications [13], while there do not appear to be any differences in the rates of incisional hernia, operating time, inpatient length of stay, and patient quality of life.[14]
