Introduction:
Neonates with intestinal perforation often require laparotomy and intestinal stoma creation, with the stoma placed in either the laparotomy incision or a separate site. We aimed to investigate if stoma location is associated with risk of postoperative wound complications.
Methods:
A multi-institutional retrospective review was performed for neonates ≤3 mo who underwent emergent laparotomy and intestinal stoma creation for intestinal perforation between January 1, 2009 and April 1, 2021. Patients were stratified by stoma location (laparotomy incision versus separate site). Outcomes included wound infection/dehiscence, stoma irritation, retraction, stricture, and prolapse. Multivariable regression identified factors associated with postoperative wound complications, controlling for gestational age, age and weight at surgery, and diagnosis.
Results:
Overall, 79 neonates of median gestational age 28.8 wk (interquartile range [IQR]: 26.0-34.2 wk), median age 5 d (IQR: 2-11 d) and median weight 1.4 kg (IQR: 0.9-2.42 kg) had perforated bowel from necrotizing enterocolitis (40.5%), focal intestinal perforation (31.6%), or other etiologies (27.8%). Stomas were placed in the laparotomy incision for 41 (51.9%) patients and separate sites in 38 (48.1%) patients. Wound infection/dehiscence occurred in 7 (17.1%) neonates with laparotomy stomas and 5 (13.2%) neonates with separate site stomas (P = 0.63). There were no significant differences in peristomal irritation, stoma retraction, or stoma stricture between the two groups. On multivariable regression, separate site stomas were associated with increased likelihood of prolapse (odds ratio 6.54; 95% confidence interval: 1.14-37.5).
Conclusions:
Stoma incorporation within the laparotomy incision is not associated with wound complications. Separate site stomas may be associated with prolapse. Patient factors should be considered when planning stoma location in neonates undergoing surgery for intestinal perforation.

Ostomy Care
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:
