Purpose
Aim of this study was to analyse feasibility, safety and effectiveness of laparoscopic transperitoneal hernia repair (TAPP) approach to inguinal hernias in the emergency setting, with a ...longer follow-up than the studies present in literature.
Methods
We retrospectively analysed all patients who underwent emergency TAPP hernia repair in San Marco Hospital (Zingonia, Italy), from September 2010 to June 2020. A prospectively collected database of 685 consecutive TAPP hernia repair was reviewed. Feasibility and safety were evaluated through operative time, conversion rate, perioperative mortality, morbidity and prosthesis infection rate. Effectiveness was assessed by recurrence and complication rate, acute (during admission) and chronic (during follow-up) pain by Visual Analogic Scale (VAS), and recovery to normal activity in a long-term follow-up (mean period 1718 days).
Results
The final study group included 47 patients. The mean age was 59.6 years (range 22–89), 29 patients were male and 18 were female. The mean operation time was 64 min. Two cases were converted to open approach (4%). In four cases bowel resection became necessary (8.5%). Appendicectomy and omentectomy occurred once and twice, respectively (2% and 4%), and orchiectomy was required in two patients (4%). Seroma was the only postoperative complication that we registered in four patients. During a mean follow-up period of 1718 days, there was no recurrence of the hernia or other complications. Five patients referred mild occasional groin pain (VAS < 3), with quick relief without taking any pain killers.
Conclusion
TAPP approach is a safe, feasible and effective therapeutic option for groin hernias in emergency setting. No recurrence or severe complications were reported in over 4 years of follow-up.
The outcomes of liver surgery worldwide remain unknown. The true population-based outcomes are likely different to those vastly reported that reflect the activity of highly specialized academic ...centers. The aim of this study was to measure the true worldwide practice of liver surgery and associated outcomes by recruiting from centers across the globe. The geographic distribution of liver surgery activity and complexity was also evaluated to further understand variations in outcomes.
LiverGroup.org was an international, prospective, multicenter, cross-sectional study following the Global Surgery Collaborative Snapshot Research approach with a 3-month prospective, consecutive patient enrollment within January-December 2019. Each patient was followed up for 90 days postoperatively. All patients undergoing liver surgery at their respective centers were eligible for study inclusion. Basic demographics, patient and operation characteristics were collected. Morbidity was recorded according to the Clavien-Dindo Classification of Surgical Complications. Country-based and hospital-based data were collected, including the Human Development Index (HDI). (NCT03768141).
A total of 2159 patients were included from six continents. Surgery was performed for cancer in 1785 (83%) patients. Of all patients, 912 (42%) experienced a postoperative complication of any severity, while the major complication rate was 16% (341/2159). The overall 90-day mortality rate after liver surgery was 3.8% (82/2,159). The overall failure to rescue rate was 11% (82/ 722) ranging from 5 to 35% among the higher and lower HDI groups, respectively.
This is the first to our knowledge global surgery study specifically designed and conducted for specialized liver surgery. The authors identified failure to rescue as a significant potentially modifiable factor for mortality after liver surgery, mostly related to lower Human Development Index countries. Members of the LiverGroup.org network could now work together to develop quality improvement collaboratives.
Liquid chromatography coupled with mass spectrometry (LC-MS) has been increasingly used for screening purposes in forensic toxicology. High versatility and low time/resource consumption are the main ...advantages of this technology. Numerous multi-analyte methods have been validated in order to face the analytical challenge of new psychoactive substances (NPSs). However, forensic toxicologists must focus the attention also on "classical" NPSs and medicines, such as benzodiazepines (BDZs) and prescription opioids. In this paper, a new method for the simultaneous detection of 169 substances (120 NPSs and 49 other drugs) in hair by LC-MS-MS is described. After the decontamination of hair samples with dichloromethane, a 20-mg aliquot of the sample was mixed with 1 mL of methanol (MeOH; 0.1% of formic acid) and then sonicated at room temperature for 2 h. The mixture was then dried under nitrogen stream and reconstituted with 100 µL of MeOH. LC separation was achieved with a 100-mm-long C18 column in 35 min, and mass acquisition was performed in dynamic multiple reaction monitoring mode and in positive ionization. The analysis results were very sensitive, with the limit of quantification ranging from 0.07 to 10.0 pg/mg. Accuracy and precision were always within the acceptable criteria. Matrix effect and recovery rate ranges were from -21.3 to + 21.9% and from 75.0 to 99.3%, respectively. The new method was successfully applied in a preliminary study on the prevalence of NPSs, BDZs and other substances in case of driving license issuance. In 14% of cases, BDZs/antidepressants (mainly trazodone, diazepam/nordiazepam and flunitrazepam) were found. Codeine, ketamine, methylone and mephedrone were also detected.
