            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). There is significant interest in further reducing the trauma associated with surgical procedures. Although a number of observational studies have suggested that SPLC is a feasible alternative to CLC, there is a lack of data from randomized studies validating any benefit over CLC. Eligible patients were randomized to receive SPLC or CLC. Operative and perioperative outcomes, including cosmesis and QOL were analyzed. Forty-three patients were randomized to SPLC (n = 21) or CLC (n = 22). There were no significant differences between groups for most preoperative demographics, American Society of Anesthesiology score, gallstone characteristics, local inflammation, blood loss, or length of stay. Patients undergoing SPLC were older than those receiving CLC (57.3 years vs. 45.8 years, P < 0.05). Operative times for SPLC were greater than CLC (88.5 minutes vs. 44.8 minutes, P < 0.05). Overall and cosmetic satisfaction, QOL as determined by the SF-36 survey, postoperative complications, and post-operative pain scores between discharge and 2-week postoperative visit were not significantly different between groups. Wound infection rates were similar in both groups. The SPLC group contained 1 retained bile duct stone, 1-port site hernia, and 1 postoperative port site hemorrhage. 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.

              Single-incision laparoscopic cholecystectomy is associated with improved cosmesis scoring at the cost of significantly higher hernia rates: 1-year results of a prospective randomized, multicenter, single-blinded trial of traditional multiport laparoscopic cholecystectomy vs single-incision laparoscopic cholecystectomy.

              Minimally invasive techniques have become an integral part of general surgery with recent investigation into single-incision laparoscopic cholecystectomy (SILC). This study presents the final 1-year results of a prospective, randomized, multicenter, single-blinded trial of SILC vs multiport cholecystectomy (4PLC). Patients with biliary colic and documented gallstones or polyps or with biliary dyskinesia were randomized to SILC vs 4PLC. Data measures included operative details, adverse events, and conversion to 4PLC or laparotomy. Patients were followed for 12 months. Two hundred patients underwent randomization to SILC (n = 119) or 4PLC (n = 81). Enrollment ranged from 1 to 50 patients with 4 sites enrolling >25 patients. Total adverse events were not significantly different between groups (36% 4PLC vs 45% SILC; p = 0.24), as were severe adverse events (4% 4PLC vs 10% SILC; p = 0.11). Incision-related adverse events were higher after SILC (11.7% vs 4.9%; p = 0.13), but all of these were listed as mild or moderate. Total hernia rates were 1.2% (1 of 81) in 4PLC patients vs 8.4% (10 of 119) in SILC patients (p = 0.03). At 1-year follow-up, cosmesis scores continued to favor SILC (p < 0.0001). Results of this trial show SILC to be a safe and feasible procedure when compared with 4PLC, with similar total adverse events but with an identified significant increase in hernia formation. Cosmesis scoring and patient preference at 12 months continue to favor SILC, and more than half of the patients were willing to pay more for a single-site surgery over a standard laparoscopic procedure. Additional longer-term population-based studies are needed to clarify if this increased rate of hernia formation as compared with 4PLC will continue to hold true.
