Efficacy of laparoscopic-assisted approach for reversal of Hartmann's procedure: results from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database.

Introduction: Morbidity after reversal of Hartmann's procedure remains high. The laparoscopic approach (LAP) may be associated with lower morbidity versus open Hartmann's closure. This study's aim is to compare results after LAP and OPEN colostomy takedown and Hartmann's reversal.

Methods: The American College of Surgeons National Surgical Quality Improvement Program database was queried from 2005 to 2012 for CPT procedure codes 44227 (LAP) and 44626 (OPEN). Exclusion criteria included: ventilator dependence, ASA class 4 or 5, SIRS, sepsis, emergency case, and advanced malignancy. Demographic parameters were assessed as well as comorbidities and short-term outcomes. Statistical methods used include Fisher's exact test for categorical variables and Student's t test for continuous variables.

Results: In total, 4,148 patients underwent stoma closure and Hartmann's reversal (LAP 732 [17.6 %], OPEN 3,416 [82.3 %]). The mean BMI was lower in the LAP (mean ± SD 27.6 ± 6.6) versus OPEN group (28.3 ± 6.8, p = 0.012). The groups were similar as regards comorbidities except for dyspnea (LAP 5.6 %, OPEN 7.8 %, p = 0.043). The mean surgery times were similar and the median LOS shorter in the LAP versus OPEN groups (5 vs 6 days, p < 0.0001). A lower overall morbidity rate was noted for the LAP group (18.4 % vs OPEN 27 %, p < 0.0001) but mortality was statistically similar. Lower rates were noted in the LAP group for the following complications: incisional SSI (10.4 vs 14.1 %, p = 0.033), organ space SSI (3.1 vs 5.0 %, p = 0.033), UTI (1.6 vs 3.3 %, p = 0.005), sepsis (3.4 vs 6.0 %, p = 0.038), and reoperation (3.1 vs 5.4 %, p = 0.011).

Conclusion: Only 18 % of Hartmann's reversal's were done using LAP methods. The LAP and OPEN groups were similar except for gender, BMI, and dyspnea history. LAP methods were associated with a 1 day LOS benefit and significantly lower overall morbidity and lower rates of incisional and deep SSI, UTI, sepsis, and reoperations. Operative length was similar. The short-term results of the LAP approach are superior to the OPEN results.
