Abstract

Purpose

Restorative proctocolectomy (RPC) is performed for patients with refractory ulcerative colitis (UC). This operation is performed in 2 or 3 stages and involves forming a diverting loop ileostomy thought to protect patients from complications related to anastomotic leak. However, some advocate for a modified 2-stage approach, consisting of subtotal colectomy followed by completion proctectomy and ileal pouch anal anastomosis without diverting ileostomy. We present a systematic review and meta-analysis comparing postoperative complication rates between modified 2-stage and traditional RPC with ileal pouch anal anastomosis.

Methods

Records were sourced from PubMed/Embase databases. Studies comparing postoperative complications following RPC for ulcerative colitis (UC) were selected according to PRISMA guidelines comparing modified 2-stage (exposure), classic 2-stage, and 3-stage approaches (comparators). The primary outcome measure was safety as measured by postoperative complication rates. We employed random effects meta-analysis.

Results

We included ten observational studies including 1727 patients (38% modified 2-stage). Among pediatric patients, modified 2-stage approaches had higher rates of anastomotic leak than 3-stage approaches (p = 0.03). Among adult cohorts with lower preoperative biologic use rates, modified 2-stage approaches had lower leak rates than classic 2-stage approaches (p < 0.001).

Conclusions

The modified 2-stage approach may be safe for adult patients who otherwise require a 3-stage approach while reducing costs and length of stay. Pediatric patients may benefit from lower leak rates when receiving 3-stage compared with modified 2-stage approaches, especially when on biologics. The modified 2-stage approach may be safer than the classic 2-stage approach for adult patients with lower biologic exposure.

Karpaltunnelsyndrom BDC Leitlinien Webinare

CME: 2 Punkte

Das Karpaltunnelsyndrom ist die häufigste Kompressionsneuropathie peripherer Nerven. Obwohl die Anamnese mit dem nächtlichen Einschlafen der Hand (Brachialgia parästhetica nocturna) sehr typisch ist, ist eine klinisch-neurologische Untersuchung und Elektroneurografie in manchen Fällen auch eine Neurosonografie erforderlich. Im Anfangsstadium sind konservative Maßnahmen (Handgelenksschiene, Ergotherapie) empfehlenswert. Bei nicht Ansprechen der konservativen Therapie oder Auftreten von neurologischen Ausfällen ist eine Dekompression des N. medianus am Karpaltunnel indiziert.
