Short-Term Outcomes in Patients Undergoing Virtual/Ghost Ileostomy or Defunctioning Ileostomy after Anterior Resection of the Rectum: A Meta-Analysis.

ABSTRACT:

Background and objectives

Anterior rectal resection (ARR) represents one of the most frequently performed methods in colorectal surgery, mainly carried out for rectal cancer (RC) treatment. Defunctioning ileostomy (DI) has long been chosen as a method to "protect" colorectal or coloanal anastomosis after ARR. However, DI does not rule out risks of more or less serious complications. A proximal intra-abdominal closed-loop ileostomy, the so-called virtual/ghost ileostomy (VI/GI), could limit the number of DIs and the associated morbidity.

Materials and methods

We performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) guidelines. Meta-analysis was performed by use of RevMan [Computer program] Version 5.4.

Results

The five included comparative studies (VI/GI or DI) covering an approximately 20-year study period (2008-2021). All included studies were observational ones and originated from European countries. Meta-analysis indicated VI/GI as significantly associated with lower short-term morbidity rates related to VI/GI or DI after primary surgery (RR: 0.21, 95% CI: 0.07-0.64, p = 0.006), fewer dehydration (RR: 0.17, 95% CI: 0.04-0.75, p = 0.02) and ileus episodes after primary surgery (RR: 0.20, 95% CI: 0.05-0.77, p = 0.02), fewer readmissions after primary surgery (RR: 0.17, 95% CI: 0.07-0.43, p = 0.0002) and readmissions after primary surgery plus stoma closure surgery (RR: 0.14, 95% CI: 0.06-0.30, p < 0.00001) than the DI group. On the contrary, no differences were identified in terms of AL after primary surgery, short-term morbidity after primary surgery, major complications (CD ≥ III) after primary surgery and length of hospital stay after primary surgery. Conclusions: Given the significant biases among meta-analyzed studies (small overall sample size and the small number of events analyzed, in particular), our results require careful interpretation. Further randomized, possibly multi-center trials may be of paramount importance in confirming our results.

Project description:IntroductionAnastomotic leakage is the most important complication in colorectal surgery occurring in up to 20% after low anterior rectal resection. Therefore, a diverting ileostomy is usually created during low anterior resection to protect the anastomosis or rather to diminish the consequences in case of anastomotic leakage. The so-called virtual or ghost ileostomy is a pre-stage ostomy that can be easily exteriorised, if anastomotic leakage is suspected, in order to avoid the severe consequences of anastomotic leakage. On the other hand, an actual ileostomy can be avoided in patients, who do not develop anastomotic leakage.Methods and analysisThe GHOST trial is a randomised controlled pilot trial comparing ghost ileostomy with conventional loop ileostomy in patients undergoing low anterior resection with total mesorectal excision for rectal cancer. After screening for eligibility and obtaining informed consent, a total of 60 adult patients are included in the trial. Patients are intraoperatively randomised to the trial groups in a 1:1 ratio after assuring that none of the intraoperative exclusion criteria are present. The main outcome parameter is the comprehensive complication index as a measure of safety. Further outcomes include specific complications, stoma-related complications, complications of ileostomy closure, frequency of transformation of ghost ileostomy into conventional ileostomy, frequency of terminal ostomy creation, proportion of patients with an ostomy at 6 months after index surgery, anorectal function (Wexner score) and quality of life assessed by the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 and CR29 questionnaires. Follow-up for each individual patient will be 6 months.Ethics and disseminationThe GHOST trial has been approved by the Medical Ethics Committee of Heidelberg University (reference number S-694/2017). If the intervention proves to be safe, loop ileostomy could be spared in a large proportion of patients, thus also avoiding stoma-related complications and a second operation (ileostomy closure) with its inherent complications in these patients.Trial registration numberGerman Clinical Trials Registry (DRKS00013997); Universal Trial Number: U1111-1208-9742.
