RESUMO
INTRODUCTION: Asian American and Native Hawaiian-Pacific Islanders (AAPI) are the fastest growing racial-ethnic group, with 18.9 million people in 2019, and is predicted to rise to 46 million by 2060. Colorectal cancer (CRC) is the most common cancer in AAPI men and the third most common in women. Treatment techniques like laparoscopic colectomy (LC) emerged as the standard of care for CRC resections; however, new robotic technologies can be advantageous. Few studies have compared clinical outcomes across minimally invasive approaches for AAPI patients with CRC. This study compares utilization and clinical outcomes of LC versus robotic colectomies (RCs) in AAPI patients. METHODS: We queried the American College of Surgeons National Surgical Quality Improvement Program database for elective RC and LC in AAPI patients from 2012 to 2020. Outcomes included unplanned conversion to open, operative time, complications, 30-d mortality, and length of stay. Multivariable logistic regression analyses assessed the association between outcomes and the operative approach. RESULTS: Between 2012 and 2020, 83,841 patients underwent elective LC or RC. Four thousand six hundred fifty-eight AAPI patients underwent 3817 (82%) LCs and 841 (18%) RCs. In 2012, all procedures were performed laparoscopically; by 2020, 27% were robotic. Mean operative time was shorter in LC (192 versus 249 min, P < 0.001). On multivariable logistic regression, there was no difference in infection (odds ratio [OR] 0.8, 95% confidence interval [CI] 0.59-1.12), anastomotic leak (OR 0.97, 95% CI 0.59-1.61), or death (OR 0.9, 95% CI 0.31-2.61). Length of stay was shorter for RC (-0.44 d, 95% CI -0.71 to -0.18 d). CONCLUSIONS: Overall, AAPI postoperative outcomes are similar between LC and RC. Future studies that evaluate costs and resource utilization can assist hospitals in determining whether implementing robotic-assisted technologies in their hospitals and communities will be appropriate.
RESUMO
BACKGROUND: Prior studies have shown comparable outcomes between laparoscopic and robotic approaches across a range of surgeries; however, these have been limited in size. This study investigates differences in outcomes following robotic (RC) vs laparoscopic (LC) colectomy across several years utilizing a large national database. METHODS: We analyzed data from ACS NSQIP for patients who underwent elective minimally invasive colectomies for colon cancer from 2012 to 2020. Inverse probability weighting with regression adjustment (IPWRA) incorporating demographics, operative factors, and comorbidities was used. Outcomes included mortality, complications, return to the operating room (OR), post-operative length of stay (LOS), operative time, readmission, and anastomotic leak. Secondary analysis was performed to further assess anastomotic leak rate following right and left colectomies. RESULTS: We identified 83,841 patients who underwent elective minimally invasive colectomies: 14,122 (16.8%) RC and 69,719 (83.2%) LC. Patients who underwent RC were younger, more likely to be male, non-Hispanic White, with higher body mass index (BMI) and fewer comorbidities (for all, P < 0.05). After adjustment, there were no differences between RC and LC for 30-day mortality (0.8% vs 0.9% respectively, P = 0.457) or overall complications (16.9% vs 17.2%, P = 0.432). RC was associated with higher return to OR (5.1% vs 3.6%, P < 0.001), lower LOS (4.9 vs 5.1 days, P < 0.001), longer operative time (247 vs 184 min, P < 0.001), and higher rates of readmission (8.8% vs 7.2%, P < 0.001). Anastomotic leak rates were comparable for right-sided RC vs LC (2.1% vs 2.2%, P = 0.713), higher for left-sided LC (2.7%, P < 0.001), and highest for left-sided RC (3.4%, P < 0.001). CONCLUSIONS: Robotic approach for elective colon cancer resection has similar outcomes to its laparoscopic counterpart. There were no differences in mortality or overall complications, however anastomotic leaks were highest after left RC. Further investigation is imperative to better understand the potential impact of technological advancement such as robotic surgery on patient outcomes.

BACKGROUND: Management of antithrombotic therapy with warfarin in patients undergoing fistulograms and possible interventions is controversial and difficult because of lack of adequate outpatient bridging options. Our goal was to assess periprocedural outcomes in patients managed using different anticoagulation strategies. METHODS: A retrospective, single-institution analysis of all patients on chronic anticoagulation with warfarin undergoing fistulograms from 2011 to 2017 was performed. Anticoagulation management strategies were classified as suspended warfarin (SW), continued warfarin (CW), and a heparin bridge with suspended warfarin (HB). Periprocedural outcomes were analyzed. RESULTS: There were 87 patients on chronic anticoagulation with warfarin who underwent 175 fistulograms. Median age was 63 years, and 43.4% were women. Indications for warfarin included atrial fibrillation (53%), prior pulmonary embolism/deep vein thrombosis (29%), and hypercoagulable state (14%). Distribution was SW (60%), CW (26%), and HB (14%). Approximately half (53%) were same-day procedures, 30% occurred during access-related admissions, and 14% were performed during nonaccess-related admissions. Common indications for a fistulogram included difficulty with dialysis (63.4%), access thrombosis (20.6%), and poor maturation (10.3%). Interventions included angioplasty (82.9%), thrombectomy/embolectomy (20.6%), and stenting (8.6%). Thirty-day outcomes for SW versus CW versus HB were similar for bleeding complications (5.7%, 6.5%, 8.3%; P = 0.89), systemic thrombotic complications (3.8%, 2.2%, 0%; P = 0.569), access rethrombosis (7.6%, 13%, 12.5%; P = 0.517), and tunneled dialysis catheter placement (11.4%, 13%, 12.5%; P = 0.958). After excluding procedures performed during a nonaccess-related admission, length of stay (LOS) was highest among HB (9.6 ± 7.8 days) compared with SW (2.6 ± 5.9 days) and CW (1 ± 2.8 days), (P < 0.0001). CONCLUSIONS: CW therapy in patients undergoing fistulograms was not associated with increased morbidity and was associated with shorter LOS. Bridging with heparin is not associated with improved outcomes, warranting a thorough consideration of continuing warfarin is safe and may streamline preservation of dialysis accesses without significantly increasing resource utilization.

BACKGROUND: We sought to examine differences in outcomes for Black and White patients undergoing robotic or laparoscopic colectomy to assess the potential impact of technological advancement. METHODS: We queried the ACS-NSQIP database for elective robotic (RC) and laparoscopic (LC) colectomy for cancer from 2012 to 2020. Outcomes included 30-day mortality and complications. We analyzed the association between outcomes, operative approach, and race using multivariable logistic regression. RESULTS: We identified 64,460 patients, 80.9% laparoscopic and 19.1% robotic. RC patients were most frequently younger, male, and White, with fewer comorbidities (P â< â0.001). After adjustment, there was no difference in mortality by approach or race. Black patients who underwent LC had higher complications (OR 1.10, 95% CI 1.03-1.08, P â= â0.005) than their White LC counterparts and RC patients. CONCLUSIONS: Robotic colectomy was associated with lower rates of complications in minority patients. Further investigation is required to identify the causal pathway that leads to our finding.
