Trends in surgical volume and in-hospital mortality among United States cirrhosis hospitalizations.

BACKGROUND: In the aging population of patients with cirrhosis in the United States, there is a potentially increased need for surgical procedures. However, individuals with cirrhosis have increased perioperative risk relative to patients without cirrhosis. We sought to quantify temporal trends in cirrhosis surgical procedures and in-hospital mortality in relation to surgical procedure type, elective admission status and compensated vs. decompensated status. METHODS: We performed a retrospective cohort study of cirrhosis hospitalizations between 2005 and 2014 using the National Inpatient Sample. Surgical procedures of interest included cholecystectomy, hernia repair, and major abdominal, orthopedic and cardiovascular surgery. We plotted trends in volume and in-hospital mortality by procedure type, and used linear regression to test the significance of trends. RESULTS: While the number of cirrhosis hospitalizations increased over time, the number of surgeries per 1000 admissions decreased (b=-1.454, P<0.001). When stratified by elective admission status, elective major orthopedic surgeries significantly increased over time (b=177.9; P<0.001). In-hospital mortality rates for most surgeries were significantly higher in the non-elective vs. elective setting (each P<0.001). In patients with compensated cirrhosis, there was a significant increase in the number of orthopedic (b=272.4; P<0.001) and hernia repair surgeries over time (b=191.1; P<0.001). Overall, there was significantly greater in-hospital mortality among patients with decompensated cirrhosis (each P<0.05). Q. Please mention the exact P-value unless <0.001. CONCLUSIONS: Despite an increasing number of cirrhosis hospitalizations, the decreasing relative number of cirrhosis surgeries may indicate progressive surgical risk aversion. Future cirrhosis surgical risk scores should consider surgical procedure type, elective/non-elective status, and decompensation status.

Effects of Metformin Exposure on Survival in a Large National Cohort of Patients With Diabetes and Cirrhosis.

BACKGROUND & AIMS: Type II diabetes mellitus worsens the prognosis of cirrhosis. Multiple medications including metformin and statins often are co-administered to manage patients with diabetes. The aim of this study was to assess the impact of metformin exposure on mortality, hepatic decompensation, and hepatocellular carcinoma in individuals with diabetes and cirrhosis, controlling for multiple concomitant exposures. METHODS: We performed a retrospective cohort study of patients with cirrhosis diagnosed between January 1, 2008, through June 30, 2016, in the Veterans Health administration. Marginal structural models and propensity-matching approaches were implemented to quantify the treatment effect of metformin in patients with pre-existing diabetes with or without prior metformin exposure. RESULTS: Among 74,984 patients with cirrhosis, diabetes mellitus was present before the diagnosis of cirrhosis in 53.8%, and was diagnosed during follow-up evaluation in 4.8%. Before the diagnosis of cirrhosis, 11,114 patients had active utilization of metformin. In these patients, metformin, statin, and angiotensinogen-converting enzyme inhibitor/angiotensin-2-receptor blocker exposure were associated independently with reduced mortality (metformin hazard ratio, 0.68; 95% CI, 0.61-0.75); metformin was not associated with reduced hepatocellular carcinoma or hepatic decompensation after adjustment for concomitant statin exposure. For patients with diabetes before a diagnosis of cirrhosis but no prior metformin exposure, metformin similarly was associated with reduced mortality (hazard ratio, 0.72; 95% CI, 0.35-0.97), but not with reduced hepatocellular carcinoma or hepatic decompensation. CONCLUSIONS: Metformin use in patients with cirrhosis and diabetes appears safe and is associated independently with reduced overall, but not liver-related, mortality, hepatocellular carcinoma, or decompensation after adjusting for concomitant statin and angiotensinogen-converting enzyme inhibitor/angiotensin-2-receptor blocker exposure.

A National Snapshot of Patient-Reported Outcomes Comparing Types of Abdominal Flaps for Breast Reconstruction.

BACKGROUND: This study aimed to identify differences in patient-reported abdominal well-being, satisfaction, and quality of life in women with muscle-preserving free abdominal versus pedicle transverse rectus abdominis musculocutaneous (TRAM) flap for breast reconstruction. METHODS: Women with a history of breast cancer surgery were recruited from the Army of Women foundation to take the BREAST-Q and a background questionnaire. Descriptive statistics and regression analyses were used to compare abdominal physical well-being, breast satisfaction, chest physical, psychosocial well-being, and sexual well-being in women undergoing free versus pedicle TRAM flaps. RESULTS: Of 657 women, 273 (41 percent) underwent free flap surgery and 384 (58 percent) underwent pedicle TRAM flap surgery. Compared with unilateral pedicle TRAM flaps, those with unilateral free flaps scored an average of 9.5 points higher (95 percent CI, 5.4 to 13.6; p < 0.0001) and those with bilateral free flaps reported no difference in physical well-being of the abdomen. Compared with bilateral pedicle TRAM flaps, the following groups scored higher in physical well-being of the abdomen: unilateral free flaps, an average of 17.4 (95 percent CI, 11.5 to 23.3; p < 0.0001); bilateral free flaps, an average of 6.8 (95 percent CI, 0.3 to 13.3; p = 0.04); and unilateral pedicle TRAM flaps, an average of 7.9 (95 percent CI, 2.4 to 13.4; p = 0.005) higher. Women with bilateral pedicle flaps reported sexual well-being scores 7.4 (95 percent CI, 0.6 to 14.3; p = 0.03) and 6.8 (95 percent CI, 0.3 to 13.2; p = 0.04) points lower than those with unilateral free and unilateral pedicle flaps. CONCLUSIONS: Muscle-preserving techniques result in improved abdominal wall function and decreased morbidity compared with pedicle TRAM flap reconstruction. These data highlight the importance of offering patients the option of microsurgical techniques.
