Association of Open Approach vs Laparoscopic Approach With Risk of Surgical Site Infection After Colon Surgery.

ABSTRACT: Importance:Colon surgery is associated with a high rate of surgical site infection (SSI), and there is an urgent need for strategies to reduce infection rates. Objective:To assess whether laparoscopic colon surgery is associated with a lower surgical site infection rate than open-approach laparoscopy, especially in patients with medically complex conditions. Design, Setting, and Participants:This cohort study used previously validated diagnosis and procedure codes from Medicare beneficiaries who underwent colon surgery from January 1, 2009, to November 30, 2013. Analyses were performed from August 1 to December 31, 2018. Main Outcomes and Measures:Outcome measures were SSI events, medical comorbidities, and laparoscopic or open approach procedures. Results:A total of 229 726 patients (mean [SD] age, 74.3 [9.4] years; 128 499 [55.9%] female) underwent colon procedures. There were 105 144 laparoscopic procedures and 124 582 open procedures. The overall mean SSI rate was 6.2%, varying by surgical procedure from 5.8% to 7.6%. Among the full study population, adjusted model results showed a significant association of laparoscopy with lower odds of SSI (odds ratio, 0.43; 95% CI, 0.41-0.46; P < .001). When stratified by surgical approach, the mean SSI rates were 4.1% (procedure-specific range, 3.9%-5.1%) for the laparoscopic approach and 7.9% (procedure-specific range, 7.4%-10.2%) for the open approach. When stratified by Elixhauser score groups, the mean SSI rates were 6.2% (procedure-specific range, 3.2%-8.7%) for group 1 (0-1 comorbidity), 5.5% (procedure-specific range, 3.6%-11.1%) for group 2 (2 comorbidities), and 6.6% (procedure-specific range, 4.6%-10.6%) for group 3 (3-13 comorbidities). An interaction was also observed between laparoscopic approach and Elixhauser groups, with increased odds of SSI among patients who had 3 to 13 comorbidities present at the time of the procedure (odds ratio, 1.21; 95% CI, 1.11-1.32) compared with patient groups with fewer comorbidities. The population attributable fraction of SSIs for use of the open approach was 34.2%. A total of 2317 of 3882 hospitals (59.7%) performed few (0%-10%) or most (>50%) procedures laparoscopically. Conclusions and Relevance:Policy changes that promote surgical education and resources for laparoscopy, especially at low-adoption hospitals, may be associated with reduced colon SSI rates. Support of the development of innovative educational policies may help achieve improvement in patient outcomes and decreased health care use in colon surgery.

Project description:ImportanceSurgery represents the mainstay treatment of colorectal liver metastases. Indications for the laparoscopic approach in this setting have been widened and there is a need to confirm the benefits of minimally invasive liver surgery (MILS) in patients with complex disease states.ObjectiveTo compare outcomes of laparoscopic surgery with those of open surgery for liver metastases from colorectal cancer, focusing on the characteristics of modern MILS and therefore overcoming possible selection bias related to different policies for patients' eligibility for MILS over time.Design, setting, and participantsA cohort study of 885 resections performed for liver metastases from colorectal cancer between January 1, 2004, and June 30, 2017, at the Hepatobiliary Surgery Unit of San Raffaele Hospital, Milano, Italy, comprising 187 laparoscopic and 698 open resections. Procedures performed using the MILS approach with a ratio of MILS to total resections per year of more than 30% were considered and were matched by propensity scores (ratio of 1:4) to procedures performed using the open approach with a ratio of MILS to total resections per year of less than 30%.Main outcomes and measuresThe primary end point was short-term outcomes, including morbidity, mortality, functional recovery, and interval between surgery and adjuvant treatments; the secondary end point was long-term outcomes.ResultsAmong this cohort (104 patients in the MILS group; 46 women and 58 men; median age, 62 years [range, 35-81 years]; and 412 patients in the open group; 181 women and 231 men; median age, 60 years [range, 37-80 years]), primary end-point data showed a significantly higher incidence of postoperative morbidity in patients who underwent open resections compared with those who underwent MILS (94 [22.8%] vs 21 [20.2%]; P = .04). Patients in the MILS group had fewer major complications (Dindo-Clavien grades III-V) compared with patients in the open group (Dindo-Clavien grades III-V; 7 [6.7%] vs 35 [8.5%]; P = .03) as well as shorter lengths of stay (median [range] duration, 3 [2-35] vs 5 [4-37] days; P = .02). Oncologic results were not compromised by the laparoscopic approach.Conclusions and relevanceIn this study, the results of the propensity score matching analysis between modern laparoscopic surgery and previous open surgery appear to confer more comparable cohorts for complexity, further supporting the advantages of laparoscopy in the surgical treatment of liver metastases from colorectal cancer. The increase in use that laparoscopy has experienced appears to be based on increased feasibility, widening of eligibility criteria for patients, enhanced clinical effectiveness, and oncologic outcomes. All these elements together suggest that up to 70% of patients appear to be candidates for this minimally invasive surgical approach in high-volume centers.

Project description:BackgroundThe aim of this study was to compare the short-term outcomes of the duodenum-first multidirectional approach (DMA) in laparoscopic right colectomy with those of the conventional medial approach to assess its safety and feasibility.MethodsThis retrospective study enrolled 120 patients who had laparoscopic surgery for right-sided colon cancer in our institution between April 2013 and December 2019. Fifty-four patients underwent colectomy using the multidirectional approach; among these, 20 underwent the DMA and 34 underwent the caudal-first multidirectional approach (CMA). Sixty-six patients underwent the conventional medial approach. Complications within 30 days of surgery were compared between the groups.ResultsThere were 54 patients in the multidirectional group [29 females, median age 72 years (range 36-91 years)] and 66 in the medial group [42 females, median age 72 years (range 41-91 years)]. Total operative time was significantly shorter in multidirectional approach patients than conventional medial approach patients (208 min vs. 271 min; p = 0.01) and significantly shorter in patients who underwent the DMA compared to the CMA (201 min vs. 269 min; p < 0.001). Operative time for the mobilization procedure was also significantly shorter in patients who underwent the DMA (131 min vs. 181 min; p < 0.001). Blood loss and incidence of postoperative complications did not differ. In 77 patients with advanced T3/T4 tumors, the DMA, CMA, and conventional medial approach were performed in 13, 21, and 43 patients, respectively. Total operative time and operative time of the mobilization procedure were significantly shorter in patients undergoing DMA. Blood loss and incidence of postoperative complications did not differ. R0 resection was achieved in all patients with advanced tumors.ConclusionsThe DMA in laparoscopic right colectomy is safe and feasible and can achieve R0 resection with a shorter operative time than the conventional medial approach, even in patients with advanced tumors.
