Summary
The conversion rate from laparoscopic to open cholecystectomy was 1.03%. Male gender, advanced age, and prior laparotomy increased the risk of conversion during gallbladder surgery.
Area of Science:
- Surgical Gastroenterology
- Minimally Invasive Surgery
Background:
- Laparoscopic cholecystectomy (LC) is the standard for benign gallbladder disease.
- Conversion to open cholecystectomy (OC) is sometimes necessary.
Purpose of the Study:
- Determine the institutional conversion rate from LC to OC.
- Identify risk factors associated with LC-OC conversion.
Main Methods:
- Retrospective study of 4668 LC cases (2000-2015).
- Matched 48 LC-OC cases with 5 control LC cases each.
- Compared 48 parameters between groups.
Main Results:
- Conversion rate was 1.03% (48/4668).
- Predictive factors for conversion included male gender, advanced age, prior laparotomy (especially post-gunshot wound), restrictive lung disease, and anemia.
- Common reasons for conversion were difficult anatomy and adhesions/inflammation.
- Converted patients had longer hospital stays.
Conclusions:
- Advanced age, male gender, comorbidities, and prior laparotomies are high-risk factors for LC-OC conversion.
- Counsel patients with risk factors preoperatively about potential conversion.
- Further research should explore experienced surgeon utilization for high-risk patients.

Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

Sometimes, there is a need to convert from one unit to another one. For instance, reading a cookbook in which quantities are expressed in units of liters or ounces may require conversion of quantities to cups. Or, when looking up directions on how to get to a location, we may be interested to know how many miles we are going to walk. In this case, we would have to convert units of feet or meters to miles.
The first step in the unit conversion is to list the given units and the units required...

01:03Prediction Intervals
3.4K
The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

01:11Bioavailability Study Design: Single Versus Multiple Dose Studies
253
Bioavailability studies are essential for understanding how a drug is absorbed, distributed, metabolized, and excreted in the body. These studies assess the extent and rate at which the active pharmaceutical agent becomes available at the site of action. The design of bioavailability studies can involve single-dose or multiple-dose regimens, each with distinct advantages and limitations.Single-dose studies are the preferred approach due to their simplicity and reduced drug exposure for...
