Summary
Purse string sutures (PS) did not show better outcomes for laparoscopic appendectomy compared to intracorporeal knotting (IK) or Hem-o-lock clips (HL). This method is no longer recommended as an initial approach due to similar complication rates and a higher wound infection rate.
Area of Science:
- Surgical techniques
- Gastrointestinal surgery
- Minimally invasive surgery
Background:
- Laparoscopic appendectomy is a common procedure for appendicitis.
- Effective closure of the appendiceal stump is crucial for preventing complications.
- Various methods exist for appendiceal stump closure, including purse string sutures, intracorporeal knotting, and Hem-o-lock clips.
Purpose of the Study:
- To compare the postoperative outcomes of laparoscopic appendectomy using purse string invaginating sutures (PS) versus intracorporeal knotting (IK) or Hem-o-lock polymeric clips (HL).
Main Methods:
- Retrospective analysis of 882 patients who underwent laparoscopic appendectomy between January 2015 and December 2017.
- Patients were divided into three groups based on the method used for appendiceal stump closure: PS (n=538), IK (n=229), and HL (n=115).
- Demographic characteristics, intraoperative findings, and postoperative complications were analyzed.
Main Results:
- No significant difference in the percentage of complicated cases across the groups (21.7% PS vs. 21.4% IK vs. 24.3% HL).
- Shorter mean hospital stay observed in the PS group compared to IK or HL groups (p < 0.05).
- Higher wound infection rate in the PS group for uncomplicated appendicitis (5.0% vs. 2.8% IK, 1.1% HL), though overall intra-abdominal infection rates were similar.
Conclusions:
- Purse string sutures did not demonstrate superior postoperative outcomes in laparoscopic appendectomy.
- The use of purse string sutures is no longer recommended as the initial approach for appendiceal stump closure at the institution.
- Intracorporeal knotting and Hem-o-lock clips appear to be viable alternatives with comparable or better outcomes regarding wound infections.

In the case of stringed instruments like the guitar, the elastic property that determines the speed of the sound produced is its linear mass density or the mass per unit length. This is simply called the linear density. If the string's linear density is constant along the string, then the linear density is simply the total mass divided by the total length.
The string's wave speed can be regulated by varying the linear density. Tension is the other property that determines the speed of...

01:22Sutures of the Skull
10.3K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

The evaluation stage signals the end of the nursing process. The nurse gathers evaluative data to assess whether or not the patient has attained the expected results. Whereas the nurse collects data in the nursing assessment to identify the patient's health concerns, the evaluation stage data determines if the indicated health issues are resolved. Evaluative data collection includes two sections: the data acquired to evaluate patient outcomes and the time criteria for data collection.

294
The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...
