Enteral Access Outcomes in Patients Hospitalized With Cardiac Disease: A Retrospective Cohort Study.

INTRODUCTION: Patients admitted with principal cardiac diagnosis (PCD) can encounter difficult inpatient stays that are often marked by malnutrition. In this setting, enteral feeding may improve nutritional status. This study examined the association of PCD with perioperative outcomes after elective enteral access procedures. METHODS: Adult patients who underwent enteral access procedures between 2018 and 2020 at a tertiary care institution were reviewed retrospectively. Differences in baseline characteristics between patients with and without PCD were adjusted using entropy balancing. Multivariable logistic and linear regressions were subsequently developed to evaluate the association between PCD and nutritional outcomes, perioperative morbidity and mortality, length of stay, and nonelective readmission after enteral access. RESULTS: 912 patients with enteral access met inclusion criteria, of whom 84 (9.2%) had a diagnosis code indicating PCD. Compared to non-PCD, patients with PCD more commonly received percutaneous endoscopic gastrostomy by general surgery and had a higher burden of comorbidities as measured by the Charlson comorbidity index. Multivariable risk adjustment generated a strongly balanced distribution of baseline covariates between patient groups (standardized differences ranged from -2.45 × 10-8 to 3.18 × 108). After adjustment, despite no significant association with in-hospital mortality, percentage change prealbumin, length of stay, or readmission, PCD was associated with an approximately 2.25-day reduction in time to meet goal feeds (95% CI -3.76 to -0.74, P = 0.004) as well as decreased odds of reoperation (adjusted odds ratio 0.28, 95% CI 0.09-0.86, P = 0.026) and acute kidney injury (adjusted odds ratio 0.24, 95% CI 0.06-0.91, P = 0.035). CONCLUSIONS: Despite having more comorbidities than non-PCD, adult enteral access patients with PCD experienced favorable nutritional and perioperative outcomes.

Learning curve of laparoscopic appendectomy in a low-resource setting: a cumulative sum analysis of operative length.

BACKGROUND: Cumulative sum (CUSUM) analysis is a valuable tool for quantifying the learning curve of surgical teams by detecting significant changes in operative length. However, there is limited research evaluating the learning curve of laparoscopic techniques in low-resource settings. The objective of this study is to evaluate the learning curve for laparoscopic appendectomy within a single surgical team in Senegal. METHODS: This was a single-center prospective study conducted from May 1, 2018, to August 31, 2023 of patients who underwent laparoscopic appendectomy at a tertiary care institution in West Africa. The AAST classification was used to describe the severity of appendicitis. Parameters studied included age, sex, operative length, conversion rate, and postoperative outcomes. To quantify the learning curve, CUSUM analysis of operative length was performed. RESULTS: A total of 81 patients were included. The mean age was 26.7 years (range 11-70 years) with a sex ratio of 1.9. Pre-operative severity according to AAST was Grade I in 75.4% (n = 61), Grade III in 7.4% (n = 6), Grade IV in 6.1% (n = 5), and Grade V in 11.1% (n = 9). Conversion occurred in 5 cases (6.1%). The average operative length was 76.8 min (range 30-180 min) and the average length of hospitalization was 2.7 days (range 1-13 days). Morbidity was observed in 3.7% (n = 3) and there were no deaths. The CUSUM analysis showed that a steady operative length was achieved after 28 procedures, with decreasing operative lengths thereafter. CONCLUSION: Surgeons in our setting overcame the learning curve for laparoscopic appendectomy after performing 28 procedures. Moreover, laparoscopic appendectomy is safe and feasible throughout the learning curve. CUSUM analysis should be applied to other laparoscopic procedures and individualized by surgical teams to improve surgical performance and patient outcomes in low-resource settings.

Bariatric surgery in patients with preoperative therapeutic anticoagulation: a 2015-2021 MBSAQIP database study.

BACKGROUND: The link between obesity and adverse cardiovascular events is well-established. With the rising prevalence of metabolic and bariatric surgery (MBS), a greater number of patients undergoing sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) may present with preoperative therapeutic anticoagulation (AC). OBJECTIVES: This study evaluated perioperative outcomes of SG and RYGB in patients on preoperative AC. SETTING: Patients reported to the 2015-2021 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database. METHODS: Adults undergoing primary SG or RYGB with and without preoperative anticoagulation (SG-AC or RYGB-AC and non-SG-AC or non-RYGB-AC, respectively) were analyzed from the 2015-2021 MBSAQIP database. Differences in baseline characteristics by AC status for each MBS were adjusted using entropy-balanced weights. Multivariable logistic and linear regressions were developed to analyze the independent association between AC and outcomes of interest. RESULTS: Of 1,178,090 patients included, 72.0% (n = 850,682) had SG and 28.0% (n = 327,408) had RYGB, of which 1.8% (n = 15,021) and 1.9% (n = 6201) had AC, respectively. Compared to non-SG-AC and non-RYGB-AC, both SG-AC and RYGB-AC encountered higher absolute 30-day rates of anastomotic leak, deep vein thrombosis and gastrointestinal bleeding. Following multivariable adjustment, SG-AC was associated with significantly greater odds of adverse cardiovascular events, anastomotic leak, gastrointestinal bleeding, and greater operative length and length of stay. RYGB-AC was associated with higher odds of readmission, unplanned ICU admission, and ED visit. CONCLUSIONS: While preoperative AC may confer distinct outcomes between SG and RYGB, this 7-year study of MBSAQIP demonstrated an overall association with greater postoperative morbidity. Management of MBS patients with preoperative AC requires consideration of thrombohemorrhagic risks.
