Severity of complications following restorative proctocolectomy in children is related to staging not diagnosis.

BACKGROUND

Restorative proctocolectomy (RPC) is performed using a variety of staged procedures for several diseases. Our aim was to assess whether the severity of complications, classified according to Clavien-Dindo, was related to the diagnosis or the procedure.

METHODS

A consecutive series of children receiving an ileoanal pouch was prospectively recorded. Complications were scored by two blinded observers. Major complications were Clavien-Dindo ≥3b. Procedures were classified as: colectomy, proctectomy and pouch or proctocolectomy and pouch. Diagnoses were classified as: ulcerative colitis, familial adenomatous polyposis or other: idiopathic constipation, total colonic Hirschsprung's disease, juvenile polyposis, Crohn's colitis, fibrosing colonopathy or necrotising enterocolitis.

RESULTS

128 children underwent 191 procedures: 61 colectomies, 63 proctectomies and 67 proctocolectomies. 84 children had ulcerative colitis, 20 had FAP and 24 had other indications. Major complications were significantly more likely with proctocolectomy (16/67, 24%) than with either colectomy (4/61, 7%) or proctectomy (8/63, 13%), p = 0.01. There was no association between diagnosis and major complications: ulcerative colitis (18/133, 14%), FAP (5/20, 25%), other (5/38, 13%) p = 0.4. There was no increase in major complications following proctectomy if a major complication had occurred during prior colectomy. Overall, 15% of procedures experienced a major complication. 6/9 stoma related complications required operative intervention.

CONCLUSIONS

The severity of complications after RPC in children is related to use of a two stage rather than three stage sequence of surgery, not the underlying diagnosis.
