Randomized Controlled Trial Comparative Study
Randomized controlled trial comparing single-port laparoscopic cholecystectomy and four-port laparoscopic cholecystectomy.
To compare short-term surgical outcomes and quality of life (QOL) between single-port laparoscopic cholecystectomy (SPLC) and classic 4-port laparoscopic cholecystectomy (CLC). ⋯ SPLC procedure time was longer and incurred more complications than CLC without significant benefits in patient satisfaction, postoperative pain and QOL. SPLC may be offered in carefully selected patients. Larger randomized trials performed later in the learning curve with SPLC may identify more subtle advantages of one method over another.

Randomized Controlled Trial
Intraperitoneal local anesthetic improves recovery after colon resection: a double-blinded randomized controlled trial.
Two wounds are created after abdominal surgery. The surgical insult to the peritoneal cavity and viscera has not been emphasized as a target for interventions. In animal models vagotomy blunts the intraperitoneal response to induced inflammation. This is not feasible in humans. However a transient chemical afferentectomy after colectomy by using neuraxial blockade (epidural) and intraperitoneal blockade may be possible. We investigated the effects of intraoperative instillation and postoperative infusion of intraperitoneal local anesthetic (IPLA) on recovery parameters after colectomy, in the setting of an established enhanced recovery after surgery (ERAS) program. ⋯ Instillation and infusion of intraperitoneal ropivacaine after colectomy improves early surgical recovery. This was associated with a blunting of postsurgical systemic cytokines and cortisol. Patients also had significantly reduced pain and opioid use over and above the effect of an epidural infusion. Therefore a transient chemical afferentectomy with clinical benefit is possible with this method. A longer IPLA infusion duration needs to be studied. This study is registered at clinicaltrials.gov and carries the ID number NCT00722709.
