Summary
Repeat sleeve gastrectomy (re-SG) is a feasible procedure for managing insufficient weight loss or weight regain after initial surgery. While complications are manageable, careful patient selection and procedural adjustments are key to optimizing outcomes.
Area of Science:
- Bariatric Surgery
- Gastroenterology
- Surgical Outcomes
Background:
- Limited data exists on repeat sleeve gastrectomy (re-SG) outcomes.
- Previous series report conflicting results on morbidity and weight loss.
- This study evaluates short- and medium-term results of re-SG.
Purpose of the Study:
- To assess the feasibility and outcomes of repeat sleeve gastrectomy (re-SG).
- To evaluate complication rates, weight loss, and co-morbidity correction after re-SG.
- To identify risk factors for gastric leak and optimal indications for re-SG.
Main Methods:
- Retrospective analysis of 46 patients undergoing re-SG between 2007 and 2016.
- Indications included insufficient excess weight loss (EWL) or weight regain.
- Comparison of outcomes based on surgical periods and indications for re-SG.
Main Results:
- The re-SG group included 46 patients with a mean BMI of 41.2 kg/m² before surgery.
- Overall complication rate was 15.2% with one death (2.1%).
- Mean EWL was 62.3% at last follow-up; weight regain cases showed better additional weight loss.
Conclusions:
- Repeat sleeve gastrectomy (re-SG) is a feasible option for selected patients.
- Adapting surgical techniques is crucial to minimize complications.
- Best outcomes were observed for gastric volumes >350 mL and weight regain, excluding primary technical failures.

Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenolphthalein is a colorless substance in any aqueous solution with a hydronium ion concentration greater than 5.0 × 10−9 M (pH < 8.3). In more basic solutions where the hydronium ion concentration is less than 5.0 × 10−9 M (pH > 8.3), it is red or pink. Substances such as phenolphthalein, which can be used to determine the pH of a solution, are...

02:24Predicting Reaction Outcomes
11.0K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...

2.9K
Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...
