          Incisional hernia rate 3 years after midline laparotomy.

          Incisional hernia is the most frequent long-term complication after visceral surgery, with an incidence of between 9 and 20 per cent 1 year after operation. Most controlled studies provide only short-term follow-up, and the actual incidence remains unclear. This study evaluated the incidence of incisional hernia up to 3 years after midline laparotomy in two prospective trials. Three-year follow-up data from the ISSAAC (prospective, multicentre, historically controlled) and INSECT (randomized, controlled, multicentre) trials focused on the rate of incisional hernia 1 and 3 years after surgery. Differences between the two groups were compared using t tests for continuous data and the χ2 test for categorical data. Analysis of 775 patients included in the two trials suggested that the incisional hernia rate increased significantly from 12.6 per cent at 1 year to 22.4 per cent 3 years after surgery (P < 0.001), a relative increase of more than 60 per cent. This follow-up of two trials demonstrated that 1 year of clinical follow-up for detection of incisional hernia is not sufficient; follow-up for at least 3 years should be mandatory in any study evaluating the rate of postoperative incisional hernia after midline laparotomy. © 2013 BJS Society Ltd.

            Incidence of incisional hernia in the specimen extraction site for laparoscopic colorectal surgery: systematic review and meta-analysis.

            The incidence of incisional hernia(IH) may be affected by the choice of specimen extraction incision. The objective of this study was to perform a systematic review and meta-analysis comparing the incidence of IH after midline and off-midline incisions in patients undergoing laparoscopic colorectal surgery.

              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.
