Our objective was to compare hospital charges and both perioperative and mid-term quality of life between single- (SILC) and multi-incision (MILC) laparoscopic cholecystectomy in a randomized controlled trial.
Patients with acute or chronic biliary disease were invited to participate. Pain scores, quality of life, and perioperative outcomes were measured. Patients were followed for 1 year postoperatively in the clinic with examination to document hernia formation.
One hundred subjects were randomized to SILC (n = 49) or MILC (n = 51). Demographics were similar for both groups except more women underwent SILC (86% vs 67%, P = .026). Operative time was greater for SILC (63.5 ± 21.0 vs 43.8 ± 24.2 minute, P < .0001). Five SILC patients required added ports. One substantial complication occurred in SILC. Pain, the use of analgesics, and duration of hospital stay were equal between groups; however, charges were greater in the SILC group ($17,602 ± $6,089 vs $13,342 ± $8,197, P < .0001). Both groups reported similar quality of life and cosmesis. At an average follow-up of SILC (16.4 ± 12.1 months) and MILC (16.2 ± 10.5 months), no novel umbilical hernias were identified.
SILC results in longer operative time and greater hospital charges with similar pain and quality of life scores compared with a standard laparoscopic approach.

    • "Indeed, since the first commercial availability of the SILS port in 2007, multiple different single ports have been made available. Multiple prospective randomized controlled trials, mainly for cholecystectomy11,12 and appendectomy,13 mostly with small numbers of patients, but more significantly during the learning curve, comparing single-port and multiport surgery, have shown consistent safety and effectiveness of the single-port approach. Similarly, single-port laparoscopic inguinal herniorrhaphy has been shown to be safe and effective.14–16 "

    ABSTRACT: Introduction: Despite an exponential rise in laparoscopic surgery for inguinal herniorrhaphy, overall recurrence rates have remained unchanged. Therefore, an increasing number of patients present with recurrent hernias after having failed anterior and laparoscopic repairs. This study reports our experience with single-incision laparoscopic (SIL) intraperitoneal onlay mesh (IPOM) repair for these hernias. Materials and methods: All patients referred with multiply recurrent inguinal hernias underwent SIL-IPOM from November 1 2009 to October 30 2013. A 2.5-cm infraumbilical incision was made and a SIL surgical port was placed intraperitoneally. Modified dissection techniques, namely, "chopsticks" and "inline" dissection, 5.5 mm/52 cm/30° angled laparoscope and conventional straight dissecting instruments were used. The peritoneum was incised above the symphysis pubis and dissection continued laterally and proximally raising an inferior flap, below a previous extraperitoneal mesh, while reducing any direct/indirect/femoral/cord lipoma before placement of antiadhesive mesh that was fixed into the pubic ramus as well as superiorly with nonabsorbable tacks before fixing its inferior border with fibrin sealant. The inferior peritoneal flap was then tacked back onto the mesh. Results: There were 9 male patients who underwent SIL-IPOM. Mean age was 55 years old and mean body mass index was 26.8 kg/m2. Mean mesh size was 275 cm2. Mean operation time was 125 minutes with hospital stay of 1 day and umbilical scar length of 21 mm at 4 weeks' follow-up. There were no intraoperative/postoperative complications, port-site hernias, chronic groin pain, or recurrence with mean follow-up of 20 months. Conclusions: Multiply recurrent inguinal hernias after failed conventional anterior and laparoscopic repairs can be treated safely and efficiently with SIL-IPOM.

    ABSTRACT: Background: Traditional metrics of postoperative outcomes (morbidity and mortality) are not useful to compare minimally invasive procedures with each other. Patient reported outcomes, such as quality of life (QOL) scores, offer an alternative approach. Compared with a large body of data in cancer treatment, the responsiveness of these instruments for minimally invasive surgery is not well described. To better define expected differences, we analyzed the reported QOL outcomes in randomized, controlled trials (RCTs) comparing single and four-port laparoscopic cholecystectomy. Methods: Searching Medline, Embase, Psychinfo, Scopus, and the Cochrane Library (1946 to Jan 2012), two independent reviewers identified RCTs comparing single with four-port cholecystectomy in adult patients using perioperative QOL assessments. The quality of the studies was assessed regarding trial design and QOL reporting. RevMan was used for mathematical analysis of the pooled outcome data using a random-effects model. Standardized mean difference estimation was utilized when pooling studies reporting different QOL tools. Statistical heterogeneity was assessed using χ(2) and I(2). Results: Of 743 citations, 37 RCTs were identified. Five studies with a total of 502 patients compared single with four-port cholecystectomy on QOL and were included. Pooled analysis was performed using preoperative and 1-month postoperative outcomes. At 1 month postoperatively, the reported effect size of perioperative QOL changes was up to 5 points (~1/2 SD) on the global SF 12 score. The largest difference in change of perioperative physical functioning was 9.9 points (~1 SD). No difference between the treatments was demonstrated. Conclusions: Reporting of QOL may improve the comparison of minimally invasive surgical procedures. This systematic review reports clinically important changes and did not demonstrate a difference between treatments at 1 month postoperatively. The optimal timing and trial design for QOL tools in this setting needs to be defined further.

    ABSTRACT: We conducted a network meta analysis (NMA) to compare different kinds of laparoscopic cholecystectomy [LC] (single port [SPLC], two ports [2PLC], three ports [3PLC], and four ports laparoscopic cholecystectomy [4PLC], and four ports mini-laparoscopic cholecystectomy [mini-4PLC]). PubMed, the Cochrane library, EMBASE, and ISI Web of Knowledge were searched to find randomized controlled trials [RCTs]. Direct pair-wise meta analysis (DMA), indirect treatment comparison meta analysis (ITC) and NMA were conducted to compare different kinds of LC. We included 43 RCTs. The risk of bias of included studies was high. DMA showed that SPLC was associated with more postoperative complications, longer operative time, and higher cosmetic score than 4PLC, longer operative time and higher cosmetic score than 3PLC, more postoperative complications than mini-4PLC. Mini-4PLC was associated with longer operative time than 4PLC. ITC showed that 3PLC was associated with shorter operative time than mini-4PLC, and lower postoperative pain level than 2PLC. 2PLC was associated with fewer postoperative complications and longer hospital stay than SPLC. NMA showed that SPLC was associated with more postoperative complications than mini-4PLC, and longer operative time than 4PLC. The rank probability plot suggested 4PLC might be the worst due to the highest level of postoperative pain, longest hospital stay, and lowest level of cosmetic score. The best one might be mini-4PLC because of highest level of cosmetic score, and fewest postoperative complications, or SPLC because of lowest level of postoperative pain and shortest hospital stay. But more studies are needed to determine which will be better between mini-4PLC and SPLC.
