Stoma prolapse is a common late complication that occurs in 2–26 % of colostomies
[1]. Prolapse is most frequently seen after loop colostomies [2] and often involves the distal limb [3]. Prolapsed stoma is rarely incarcerated or strangulated; however, such cases require
emergency surgery [3]
[4].
A 70-year-old woman suffering from obstructive rectal cancer with multiple liver and
lung metastases underwent transverse loop colostomy and subsequent chemotherapy. On
day 2 after initiation of second-line chemotherapy (infusional 5-FU, leucovorin, and
irinotecan plus ramucirumab), the distal limb of loop colostomy was prolapsed and
strangulated owing to edema. The prolapsed colon wall was entirely reddish and edematous
with a superficial brown spot at the tip ([Fig. 1]) and manual reduction using sugar as a desiccant was unsuccessful. Although emergency
surgery is usually indicated in such circumstances, it is associated with perioperative
complications due to administration of ramucirumab. Hence, we attempted a unique balloon-attached
endoscopy-assisted reduction ([Fig. 2]). An 11-mm balloon for endoscopic injection sclerotherapy (MD-47411L; Sumitomo Bakelite
Co., Ltd., Tokyo, Japan) was attached to the shaft of the colonoscope ([Fig. 3]), and it was inserted into the prolapsed stoma such that the balloon came in contact
with the invaginated inside wall. To ensure secure placement, the balloon diameter
should be smaller than the outer diameter of the prolapsed tract but slightly larger
than the inside diameter. The balloon was kept in contact with the prolapsed inside
wall while the endoscope was gradually pushed forward, and simultaneously another
operator facilitated repositioning of the inside wall with their hand. This procedure
was slowly repeated until the prolapsed stoma had been successfully reduced ([Fig. 4]). No recurrence was observed thereafter.

We describe a novel non-surgical “balloon-attached endoscopy-assisted reduction” approach
that may be a useful conservative technique for reducing an incarcerated stoma prolapse
([Video 1]).
