Prospective Randomized Comparison of Linear Endostaplers During Laparoscopic Sleeve Gastrectomy

Purpose

The development of Laparoscopic Linear Endostaplers (LLES) is crucial in minimally invasive approaches in bariatric surgery, but there have been very few published studies comparing 6-row LLES in Laparoscopic Sleeve Gastrectomy (LSG). The objective of this study was to compare two 6-row LLES in LSG.

Methods

A total of 60 patients were prospectively randomized to undergo LSG with either Medtronic Endo GIA? Tri-Staple technology (MTS) or AEON ? Endostapler(Lexington Medical) LLES. The measured parameters included patient demographics, comorbidity indices, LLES and specimen characteristics, postoperative symptoms, hospital stay, and total adverse events (AEs). Intraoperative bleeding was evaluated using five laparoscopic and corresponding endoscopic images of staple line before clip application, compared with a 1–5 Visual Analogue Scale (VAS), assessed by an independent bariatric surgeon who was blinded to the LLES used. Images of all cases were reviewed on the same day to increase test–retest reliability.

Results

Both groups were similar in patient demographics. Compared to MTS, AEON LLES group had significantly lower bleeding VAS scores in 4/5 laparoscopic images (pre-pyloric: 1.7?±?0.7 vs. 2.36?±?0.76, p?=?0.0007, mid-sleeve: 1.46?±?0.62 vs. 1.86?±?0.68, p?=?0.019, proximal sleeve: 1.6?±?0.77 vs. 2.0?±?0.83, p?=?0.038, gastro-esophageal junction: 1.43?±?0.67 vs. 1.86?±?0.77, p?=?0.014) and 3/5 endoscopic images (pre-pyloric: 1.56?±?0.56 vs. 2.36?±?0.76, p?=?0.006, incisura: 1.66?±?0.54 vs. 2.0?±?0.52, p?=?0.021, mid-sleeve: 1.63?±?0.49 vs. 2.0?±?0.45, p?=?0.005). There was no statistical difference in other parameters.

Conclusion

Both devices were equally safe and effective in terms of LLES and specimen characteristics, patient symptoms, hospital stay, and AEs. Bleeding VAS scores were significantly lower, favoring the AEON LLES.

Utility of the Brief Symptom Inventory in the Assessment of Psychological Distress

Introduction People with intellectual disabilities are now acknowledged to be susceptible to the full range of mental health disorders. This acknowledgement has resulted in the need to develop and evaluate instruments for the assessment and detection of mental health problems. This research evaluates the use of the Brief Symptom Inventory (BSI) with 200 people with mild intellectual disabilities representing community, clinical and forensic populations. Results and conclusions Results illustrate the reliability of the BSI for each of the groups and demonstrates how the Positive Symptom Total (PST) index effectively discriminates between study groups. Case rates for each group are provided. The study illustrates that the BSI could be employed as a brief multitrait assessment instrument and as a treatment outcome measure with people with an intellectual disability.     

A prolonged outbreak of ornithosis in duck processors.

In 1985 an outbreak of ornithosis affected 13 of 80 (16%) workers in a duck-processing plant. New employees were three times more likely to become cases than established employees. The highest attack rate was in those on the production line. Following the outbreak, an occupational health scheme was set up to monitor the health of new recruits to the company. Serological evidence of recent infection was demonstrated in 18 of 37 (49%) new employees tested in the first 3 months of employment. Five (14%) also had clinical evidence of ornithosis. Veterinary investigation of the ducks demonstrated a high proportion with asymptomatic chlamydial infection. It is suggested that ornithosis may be more common in duck processors than is currently supposed. Strategies to reduce occupational risks are discussed.

用健康信念模式设计健康教育项目

根据健康信念模式,有4个关键因素会影响人们的行为改变.在设计健康教育项目时我们应该考虑每一个因素.无论一个人是采取预防行为还是开始一个治疗过程,他/她都会根据他们对每一个因素的认知来决定他们未来的行为.这4个因素分别是：易感性、严重性、益处和障碍.
