Aim
The purpose of this study is to shed light on a rare complication following ileostomy closure after 3-stage IPAA for further study and discussion.
Methods
Our department IPAA database was queried for all patients who underwent 3-stage IPAA creation from 2011 through 2018. Data was reviewed and analyzed using the SPSS application. Chi-square test and Fisher’s exact test were used for categorical variables. t test or ANOVA was used for continuous variables. Significance was set at p < 0.05.
Results
Three hundred seventy-eight charts were queried. Sixty-eight complications (18.0%) were identified after ileostomy closure. Thirty-seven were small bowel obstruction or partial small bowel obstruction (SBO or pSBO, 9.79%), 5 cases of leak from ileoileostomy anastomosis (7.4%), and 4 cases of leak from pouch (5.9%). There was no significant difference in time between restorative proctocolectomy with IPAA and loop ileostomy closure with cases where a complication occurred and where one did not (p = 0.28). Eight patients developed a SIRS response in the first 5 days after surgery without an identified intraabdominal source after extensive work-up. Of these patients, 87.5% also had negative re-explorations (both open and laparoscopic). None required re-diversion, and all recovered well.
Conclusions
While SBO remains the most common complication following ileostomy closure, a surprisingly large number of presents present with a SIRS response with no identifiable source. All of these patients recovered with supportive care, and none required further intervention or diversion. This is a poorly understood phenomenon which is unique to ileostomy closure after IPAA, and further study is required.
