Male gender impact on the outcome of laparoscopic cholecystectomy

A German's Perspective on the Way toward Ambulatory Laparoscopic Cholecystectomy: A Postoperative Questionnaire

Introduction

Ambulatory surgeries are on the rise in recent years and can offer benefits to patients as well as healthcare providers. Laparoscopic cholecystectomy is one of the procedures commonly done in an ambulatory setting, in some European countries. This study aims to gather patients' perceptions towards ambulatory cholecystectomy after undergoing laparoscopic cholecystectomy in an inpatient setting.

Methods

A total of 300 patients from two different hospitals in Germany received a postoperative questionnaire aimed at evaluating their willingness to undergo an ambulatory surgery. Surgeries were performed between January 1, 2017, and July 11, 2018. Operation setting (acute vs. elective), ASA classification, length of hospital stay, age, sex, living situation and location (city vs. rural), as well as status of employment were documented.

Results

Overall, 23% of patients reported considering ambulatory laparoscopic cholecystectomy (ALC), while 77% rejected an ALC. Objections included fear of complications (69%), anticipated pain (65%), concerns about their living situation/home care (21%), other reasons (8%), nausea and vomiting (3.4%). Baseline characteristics of the participants provided no statistical significance on willingness to undergo ALC: acute versus elective (p = 0.22), ASA classification (p = 0.77), age ≥65 years versus <65 years (p = 0.60), gender (p = 0.07), living situation (p = 0.49), location (p = 0.15).

Conclusion

There is a willingness for ALC, albeit still limited. Chosen criteria did not show a significant association for positive perception of ALC.

Peri-operative Mortality Following Cholecystectomy in Australia: Potential Preventability of Adverse Events

BACKGROUND

Cholecystectomy is a commonly performed procedure; however, it is not without risks. It is crucial to constantly audit surgical outcomes in order to improve quality of care. The aim of this retrospective population-based cohort study is to identify preventable issues of clinical management associated with adverse occurrences in order to reduce mortality of cholecystectomy patients.

METHODS

Data were obtained from the Australian and New Zealand Audit of Surgical Mortality (ANZASM). It encompasses peer-reviewed first and second line assessments of management of cholecystectomy patients who died from 2005 to 2015 in Australia. Clinical Management Issues (CMIs) were identified from text in assessments and grouped into communication failures, pre-operative, intra-operative and post-operative categories. These were further classified into subthemes using thematic analysis with a data-driven approach.

RESULTS

There were 359 deaths in the study period. CMIs were present in 71 cases, with a reported total of 124 concerns or adverse events. Post-operative CMIs were the most prevalent issue [50% (62/124)], with the most common theme being delay to recognise complications (19/124). Pre-operative concerns were the second most common (n = 34). Decision to operate was questioned in 14 cases, and delay to surgery was reported in 12 cases.

CONCLUSION

ANZASM analysis has allowed us to identify modifiable adverse occurrences. This audit shows that delay to recognise complications is the most common assessment recorded. Preventive measures should be taken to improve outcomes and reduce peri-operative mortality, with an emphasis on post-operative management and enhancing communication between members of the multidisciplinary team.

DOES MALE GENDER INCREASE THE RISK OF LAPAROSCOPIC CHOLECYSTECTOMY?

Background:

Laparoscopic cholecystectomy is the preferable treatment for chronic or acute cholecystitis. Some factors may increase the rate of laparoscopic conversion to open cholecystectomy and perioperative complications. The role of gender as a risk factor for laparoscopic cholecystectomy is controversial.

Aim:

To evaluate the role of the gender on the operative findings and outcome of laparoscopic cholecystectomy.

Method:

All patients who underwent laparoscopic cholecystectomy for chronic or acute cholecystitis were included. Demographic, clinical, laboratory, imaging exams, intraoperative and postoperative data were obtained and analyzed. The data was obtained retrospectively from electronic medical records and study protocols.

Results:

Of a total 1,645 patients who were subjected to laparoscopic cholecystectomy, 540 (32.8%) were men and 1,105 (67.2%) were women. Mean age was similar in both genders (p=0.817). Operative time has longer in the male (72.48±28.50) than in the female group (65.46±24.83, p<0.001). The rate of acute cholecystitis was higher in the male (14.3%) than in the female group (5.1%, p<0.001). There was no difference between the genders in regard to the rate of conversion (p=1.0), intraoperative complication (p=1.0), postoperative complication (p=0.571), and operative mortality (p=1.0).

Conclusion:

Male gender is not an independent risk factor for laparoscopic conversion and perioperative 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.

Management of complicated gallstones in the elderly: comparing surgical and non-surgical treatment options

Objective

The aim of this study was to evaluate the differences in clinical outcomes of endoscopic retrograde cholangiopancreatography (ERCP), ERCP followed by cholecystectomy (EC) and percutaneous aspiration (PA) in the elderly population with choledocholithiasis.

Methods

We included a total of 43 338 elderly patients aged 60 years or older and 45 295 patients younger than 60 years for comparison in our study. Data were obtained from the Nationwide Inpatient Sample (Healthcare Utilization Project) for years 2001–14 by identifying patients who were admitted for gallstone complications based on the ICD 9 diagnostic code. Multiple logistic regression was used to calculate the odds of in-hospital mortality and to detect statistical differences among the treatment groups, age groups and between male and female patients. Univariate ordinary linear regression was used to compare the length of hospital stay and readmission frequency among the different age groups.

Results

The age of the patient affected mortality and the length of hospital stay after any type of procedure of gallstones removal. In a manner independent of the patient’s age, PA was associated with the highest risk of death and length of stay, while the EC was characterized by lowest mortality and ERCP by the shortest length of stay. Neither age of the patient nor the type of procedure affected the likelihood of readmission. The odds of death and the probability of readmission were not affected by patient sex. However, in patients aged between 60 and 79 years, the female gender predicted a shorter duration of stay in the hospital.

Conclusions

A patient’s age negatively affects the treatment outcomes of cholelithiasis with associated complications. The EC procedure appears to be the method of choice for the management of complicated gallstones in patients of all ages.

The Cholecystectomy As A Day Case (CAAD) Score: A Validated Score of Preoperative Predictors of Successful Day-Case Cholecystectomy Using the CholeS Data Set

BACKGROUND

Day-case surgery is associated with significant patient and cost benefits. However, only 43% of cholecystectomy patients are discharged home the same day. One hypothesis is day-case cholecystectomy rates, defined as patients discharged the same day as their operation, may be improved by better assessment of patients using standard preoperative variables.

METHODS

Data were extracted from a prospectively collected data set of cholecystectomy patients from 166 UK and Irish hospitals (CholeS). Cholecystectomies performed as elective procedures were divided into main (75%) and validation (25%) data sets. Preoperative predictors were identified, and a risk score of failed day case was devised using multivariate logistic regression. Receiver operating curve analysis was used to validate the score in the validation data set.

RESULTS

Of the 7426 elective cholecystectomies performed, 49% of these were discharged home the same day. Same-day discharge following cholecystectomy was less likely with older patients (OR 0.18, 95% CI 0.15-0.23), higher ASA scores (OR 0.19, 95% CI 0.15-0.23), complicated cholelithiasis (OR 0.38, 95% CI 0.31 to 0.48), male gender (OR 0.66, 95% CI 0.58-0.74), previous acute gallstone-related admissions (OR 0.54, 95% CI 0.48-0.60) and preoperative endoscopic intervention (OR 0.40, 95% CI 0.34-0.47). The CAAD score was developed using these variables. When applied to the validation subgroup, a CAAD score of ≤5 was associated with 80.8% successful day-case cholecystectomy compared with 19.2% associated with a CAAD score >5 (p < 0.001).

CONCLUSIONS

The CAAD score which utilises data readily available from clinic letters and electronic sources can predict same-day discharges following cholecystectomy.

The use of patient factors to improve the prediction of operative duration using laparoscopic cholecystectomy

BACKGROUND

Reliable prediction of operative duration is essential for improving patient and care team satisfaction, optimizing resource utilization and reducing cost. Current operative scheduling systems are unreliable and contribute to costly over- and underestimation of operative time. We hypothesized that the inclusion of patient-specific factors would improve the accuracy in predicting operative duration.

METHODS

We reviewed all elective laparoscopic cholecystectomies performed at a single institution between 01/2007 and 06/2013. Concurrent procedures were excluded. Univariate analysis evaluated the effect of age, gender, BMI, ASA, laboratory values, smoking, and comorbidities on operative duration. Multivariable linear regression models were constructed using the significant factors (p < 0.05). The patient factors model was compared to the traditional surgical scheduling system estimates, which uses historical surgeon-specific and procedure-specific operative duration. External validation was done using the ACS-NSQIP database (n = 11,842).

RESULTS

A total of 1801 laparoscopic cholecystectomy patients met inclusion criteria. Female sex was associated with reduced operative duration (-7.5 min, p < 0.001 vs. male sex) while increasing BMI (+5.1 min BMI 25-29.9, +6.9 min BMI 30-34.9, +10.4 min BMI 35-39.9, +17.0 min BMI 40 + , all p < 0.05 vs. normal BMI), increasing ASA (+7.4 min ASA III, +38.3 min ASA IV, all p < 0.01 vs. ASA I), and elevated liver function tests (+7.9 min, p < 0.01 vs. normal) were predictive of increased operative duration on univariate analysis. A model was then constructed using these predictive factors. The traditional surgical scheduling system was poorly predictive of actual operative duration (R ² = 0.001) compared to the patient factors model (R ² = 0.08). The model remained predictive on external validation (R ² = 0.14).The addition of surgeon as a variable in the institutional model further improved predictive ability of the model (R ² = 0.18).

CONCLUSION

The use of routinely available pre-operative patient factors improves the prediction of operative duration during cholecystectomy.

Cholecystectomy and wound complications: smoking worsens risk

BACKGROUND

In the United States, approximately 800,000 cholecystectomies are performed annually. We sought to determine the influence of preoperative smoking on postcholecystectomy wound complication rates.

MATERIALS AND METHODS

Using the National Surgical Quality Improvement Program database (2005-2011), patients aged ≥18 y who underwent elective open or laparoscopic cholecystectomy (LC) for benign gallbladder disease were identified using current procedural terminology codes. Multivariate regression was performed to determine the association between smoking status and wound complications, by surgical approach.

RESULTS

Of 143,753 identified patients, 128,692 (89.5%) underwent LC, 27,788 (19.3%) were active smokers, and 100,710 (70.2%) were females. Active smokers were younger than nonsmokers (mean + standard deviation age: 44.2 (14.9) versus 51.6 (17.9) years); P < 0.001) and had fewer comorbidities. Within 30-d postcholecystectomy, wound complications were reported in 2011 (1.4%) patients. Compared with nonsmokers, active smokers demonstrated increased odds of wound complications after both open cholecystectomy (odds ratio 1.28; P = 0.010) and LC (odds ratio 1.20; P = 0.020) after adjustment for demographic and clinical characteristics. Having wound complications increased the average postoperative length of stay by 2-4 d (P <0.001).

CONCLUSIONS

Active smokers are more likely to develop wound complications after cholecystectomy, regardless of surgical approach. Occurrence of wound complications consequently increases postoperative length of stay. Smoking abstinence before cholecystectomy may reduce the burden associated with wound complications.
