The association between body mass index and the severity of cholecystitis

Self-Reported Primary Cooking Fuels Use and Risk of Chronic Digestive Diseases: A Prospective Cohort Study of 0.5 Million Chinese Adults

BACKGROUND

Household air pollution (HAP) from inefficient combustion of solid fuels is a major health concern worldwide. However, prospective evidence on the health impacts of solid cooking fuels and risks of chronic digestive diseases remains scarce.

OBJECTIVES

We explored the effects of self-reported primary cooking fuels on the incidence of chronic digestive diseases.

METHODS

The China Kadoorie Biobank recruited 512,726 participants 30-79 years of age from 10 regions across China. Information on primary cooking fuels at the current and previous two residences was collected via self-reporting at baseline. Incidence of chronic digestive diseases was identified through electronic linkage and active follow-up. Cox proportional hazards regression models were used to estimate adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for the associations of self-reported long-term cooking fuel patterns and weighted duration of self-reported solid cooking fuel use with chronic digestive diseases incidence. Linear trend was tested by assigning the medians of weighted duration in each group and then taking those as continuous variables in the models. Subgroup analyses were undertaken across the baseline characteristics of participants.

RESULTS

During 9.1 ± 1.6 y of follow-up, 16,810 new cases of chronic digestive diseases were documented, among which 6,460 were diagnosed as cancers. Compared with long-term cleaner fuel use, self-reported long-term use of solid cooking fuels (i.e., coal, wood) was associated with elevated risks of chronic digestive diseases (HR = 1.08 ; 95% CI: 1.02, 1.13), including nonalcoholic fatty liver disease (NAFLD) (HR = 1.43 ; 95% CI: 1.10, 1.87), hepatic fibrosis/cirrhosis (HR = 1.35 ; 95% CI: 1.05, 1.73), cholecystitis (HR = 1.19 ; 95% CI: 1.07, 1.32), and peptic ulcers (HR = 1.15 ; 95% CI: 1.00, 1.33). The longer the weighted duration of self-reported solid cooking fuel use, the higher the risks of chronic digestive diseases, hepatic fibrosis/cirrhosis, peptic ulcers, and esophageal cancer (p Trend < 0.05 ). The aforementioned associations were modified by sex and body mass index (BMI). Positive associations of always solid cooking fuel use with chronic digestive disease, hepatic fibrosis/cirrhosis, NAFLD, and cholecystitis were observed among women but not men. The longer the weighted duration of self-reported solid cooking fuel use, the higher the risk of NAFLD among those with a BMI ≥ 28   kg / m 2 .

DISCUSSION

Long-term self-reported solid cooking fuels use was associated with higher risks of chronic digestive diseases. The positive association of HAP from solid cooking fuels with chronic digestive diseases indicates for an imminent promotion of cleaner fuels as public health interventions. https://doi.org/10.1289/EHP10486.

Patients with complicated gallstone disease in the emergency department: clinical impact and cost-effectiveness of emergency department disposition decision

Objective

The objective of this study was to assess the 1-year outcomes of emergency department (ED) patients with complicated gallstone disease, including surgery rates, initial admission rates, ED revisits, repeat hospitalizations, and cost.

Methods

Using 3 linked statewide databases from the Maryland Healthcare Cost and Utilization Project, we identified patients with a primary diagnosis of complicated gallstone disease treated in an ED between 2016 and 2018. We measured the healthcare use and direct costs in the ambulatory surgery, inpatient, and ED settings for 1 year after the initial ED visit. Finally, we performed a multivariate logistic regression analysis comparing initially admitted versus discharged patients.

Results

Of the 8751 patients analyzed, 86.8% were admitted to the hospital and 13.2% were discharged on their initial ED visit. Of the admitted patients, 78.7% received a cholecystectomy during the initial hospitalization plus 6.1% at a later date; of the discharged patients, 41.5% received a cholecystectomy. Admitted patients demonstrated lower recurrent gallbladder complications compared with those discharged (7.5% vs 44.5%), fewer ED revisits (4% vs 20.3%), and fewer repeat hospitalizations (4.5% vs 16.7%). Despite this, the 1-year cost in the admitted patients was higher ($9448 vs $2933). Obesity, age, and mood disorders but not race, ethnicity, or zip code were associated with admission at initial ED visit.

Conclusions

In our single-state analysis of ED patients with complications of gallstone disease, most patients are admitted on the initial visit and receive a cholecystectomy during that hospitalization. The discharged group had higher rates of 1-year complications, ED revisits, and repeat hospitalizations but lower cost.

Predictive Factors for Drain Placement After Laparoscopic Cholecystectomy

PURPOSE

Currently, surgical drainage during a laparoscopic cholecystectomy (LC) is still placed in selected patients. Evidence of the non-beneficial effect of the surgical drain comes from studies with a heterogeneous population. This preliminary study aims to identify any clinical, demographic, or intraoperative predictive factors for a surgical drain placement during LC as the first step to identify population for a prospective randomized study.

METHOD

The study was conducted in a single referral center and academic hospital between 2014 and 2018. Patients who underwent unconverted LC were divided into two groups: Group A (drain) and Group B (no drain). We explored baseline, preoperative, intraoperative characteristics, and postoperative outcomes.

RESULTS

Between 409 patients who underwent LC: 90 (22%) patients were in Group A (drain). Age >64 years, male sex, cholecystitis, Charlson comorbidity index (CCI) ≥ 1, experienced surgeon, intraoperative technical difficulties, need for an additional trocar, operative time >60 min, and estimated blood loss >10 ml were predictive factors at univariate analysis. While at multivariate analysis, cholecystitis (odds ratio [OR]: 2.8, 95% CI:1.5-5.1; p < 0.001), CCI ≥ 1 (OR:1.9, 95% CI:1.0-3.5; p = 0.05), intraoperative technical difficulties (OR: 3.6, 95% CI:1.8-6.2; p < 0.001), need of an additional trocar (OR: 2.5, 95% CI: 1.4-4.4; p < 0.005), and estimated blood loss >10 ml (OR: 3.0, 95% CI:1.7-5.3; p < 0.0001) were predictive factors for a surgical drain placement during LC.

CONCLUSIONS

This study identified predictive factors that currently drive the surgeons to a surgical drain placement after LC. Randomized prospective studies are needed to define the use of drain placement in these selected patients.

Accuracy of pre-operative parameters in predicting severe cholecystitis-A systematic review

INTRODUCTION

Severity of cholecystitis can be defined by the presence of histopathological changes such as gangrene, perforation, and empyema. Severe cholecystitis correlates with higher morbidity and longer hospital stay. The present review aimed to identify the predictors of severe cholecystitis.

METHODS

Electronic databases including PubMed, Scopus, and Cochrane library were searched in the period of January 1980 to March 2019. The main outcome of this review was to assess the predictability of pre-operative parameters such as Leukocytosis, fever, tachycardia, gallbladder wall edema, gallbladder distension, serum platelet count, and gallbladder mural striation. The role of patients' characteristics including age, gender, and diabetes mellitus in predicting severe cholecystitis was also assessed.

RESULTS

A total of 8823 patients were analysed. The mean age of patients was 67.14 ± 4.17. The parameters that had the highest Odds ratio in predicting severe cholecystitis were all findings on CT scanning and included attenuation of arterial phase, mural striation of the gallbladder, and decreased gallbladder wall enhancement.

CONCLUSION

We conclude that CT findings were the most significant predictors of severe cholecystitis. Patients with clinical and laboratory predictors of severe cholecystitis should be urgently evaluated with contrast CT scan to rule out any severe complications.

Assessment of the difficulties in laparoscopic cholecystectomy among patients at Baghdad province

Background

Laparoscopic surgery for gallbladder cholecystectomy has become the typical procedure for symptomatic gallbladder stone diseases treatment as a type of minimal invasiveness surgery associated with less pain and early recovery as there is minimal trauma of access without shrinking the exposure of operative field. The current study aimed to assess factors associated with difficult LC.

Methodology

A cross sectional study was conducted at medical city complex (Baghdad Teaching Hospital) from October 2015 to October 2016, in which all patients that were admitted for LC were examined preoperatively, underwent LC and followed postoperatively to study factors associated with difficult LC. All LC were operated by qualified senior surgeons and supervised by well-trained resident doctors. A pre-operative score system parameters were obtained from history, clinical examination and investigation findings.

Results

Laparoscopic cholecystectomy was performed for 100 patients, 78% were females and 49% were among 40–59 years of age. The preoperative scoring revealed that in 58% of the patients the score indicate difficulty, and very difficult in only 7% of the patients. Difficult and very difficult operations were significantly associated with high difficult scoring preoperatively, gender, BMI and cause of admission.

Conclusion

High difficult scoring preoperatively, gender, BMI and cause of admission can be used as predictors for difficult LC.

•

The current study aimed to assess factors associated with difficult LC.

•

Very difficult operations were associated with high difficult scoring preoperatively, gender, BMI and cause of admission.

•

Laparoscopic surgery for gallbladder cholecystectomy has become the typical procedure for symptomatic cholelithiasis treatment.

Clinical impact of body mass index on bactibilia and bacteremia

Background

The aim of this study was to evaluate the association between obesity and infected bile or bacteremia in patients with acute calculous cholecystitis.

Methods

Authors analyzed the medical records of 139 patients who had undergone cholecystectomy for the treatment of acute calculous cholecystitis from January 2007 to June 2013 in a single teaching hospital. Association of body mass index (BMI) with bactibilia and bacteremia was assessed using univariate and multivariate analysis. Clinical findings and biliary infection related data were recorded for the following variables: gender, age, alcohol and smoking history, the results of blood and bile cultures, cholesterolosis, diabetes, hypertension, and duration of the hospital stay.

Results

The microbial culture rate of bactibilia and bacteremia were 50.4% and 21.6%, respectively. In the univariate analysis, bacteremia was associated with bactibilia (OR: 4.33, p = 0.002). In the multivariate analysis for the risk factors of bactibilia, BMI and bacteremia were related with bactibilia (OR: 0.59, 95% CI: 0.42-0.84, p = 0.003) (OR: 3.32, 95% CI: 1.22-9, p = 0.02). In the multivariate analysis for the risk factors of bacteremia, BMI, bactibilia and age were related with bacteremia (OR: 0.76, 95% CI: 0.59-0.99, p = 0.04) (OR: 3.46, 95% CI: 1.27-9.45, p = 0.02) (OR: 1.05, 95% CI: 1.01-1.09, p = 0.02).

Conclusion

In this retrospective study, BMI was inversely correlated with bacteremia or bactibilia, which means obese or overweight patients are less likely to be associated with bacteremia or bactibilia in patients with acute calculous cholecystitis.

Risk factors for the clinical course of cholecystitis in patients who undergo cholecystectomy

BACKGROUNDS/AIMS

The aims of this study were to evaluate risk factors for acute cholecystitis that have been previously acknowledged and to evaluate several co-morbidities, such as hypertension, diabetes mellitus, cardiovascular disease, cerebrovascular accident and end-stage renal disease for which the prevalence rate has increased in the elderly.

METHODS

We retrospectively reviewed 611 patients who underwent laparoscopic or open cholecystectomy for cholecystitis between January 2005 and January 2010. The relationships between the clinical outcomes and the clinico-demographic factors were analyzed by univariate and multivariate analyses.

RESULTS

The diagnoses of the 611 patients who underwent laparoscopic cholecystectomy were acute cholecystitis (n=258; 42.2%) and chronic cholecystitis (n=353; 57.8%). Male gender (p<0.000), age >50 (p<0.000), fever (p<0.000), leukocytosis (p<0.000), AST elevation (p=0.009), alkaline phosphatase elevation (p<0.000) and an elevation of total bilirubin (p<0.000) were identified as risk factors for acute cholecystitis. The presence of diabetes mellitus (p=0.002) and hypertension (p=0.019) may be risk factors for acute cholecystitis.

CONCLUSIONS

For patients with risk factors for acute cholecystitis, early management, that is, early checkup and diagnosis following early cholecystectomy, is recommended before the disease progresses to an acute form of cholecystitis.
