Spade-Shaped Anastomosis after Laparoscopic Proximal Gastrectomy Using Double Suture Anchoring between the Posterior Wall of the Esophagus and the Anterior Wall of the Stomach (SPADE Operation): A Case Series

We introduced SPADE operation, a novel anastomotic method after laparoscopic proximal gastrectomy (PG). Technical modifications were performed and settled. This report aimed to demonstrate the short-term clinical outcomes after settlement. Data from 34 consecutive patients who underwent laparoscopic PG with SPADE between June 2017 and March 2020 were retrospectively reviewed. Reflux was evaluated based on the patients’ symptoms and follow-up endoscopy using Los Angeles (LA) classification and RGB Classification (Residue, Gastritis, Bile). Other complications were classified using the Clavien–Dindo method. The incidence of reflux esophagitis was 2.9% (1/34). Bile reflux was observed in six patients (17.6%), and residual food was observed in 16 patients (47.1%) in the endoscopy. Twenty-eight patients had no reflux symptoms (82.4%), while five patients (14.7%) and one patient (2.9%) had mild and moderate reflux symptoms, respectively. The rates of anastomotic stricture and ileus were 14.7% (5/34) and 11.8% (4/34), respectively. No anastomotic leakage was observed. The incidence of major complications (Clavien-Dindo grade III or higher) was 14.7%. The SPADE operation following laparoscopic PG is effective in reducing gastroesophageal reflux. Its clinical usefulness should be validated using prospective clinical trials.

Modified Incisional Negative Pressure Wound Therapy Increases Seroma Evacuation: An Ex Vivo Model

Background. Incisional negative wound pressure therapy (iNPWT) is a relatively novel dressing technique with the aim of reducing postoperative wound infections and dehiscence in high-risk wounds after all kinds of surgical procedures. There is a lack of theoretical knowledge about the way those dressing would ameliorate wound healing. One aspect is the reduction of superficial tension, but significant remaining seroma might still cause deep wound infections. The aim of this study was the evaluation of technical modifications of the standard iNPWT dressing to increase seroma evacuation. Methods. iNPWT dressings were applied on the porcine abdominal wall, and an incremental pressure ramp from 50 to 200 mmHg was performed. The resulting wound pressures were measured using (i) balloon manometry and (ii) esophageal manometry catheter. Seroma evacuation was analyzed with a seroma model. All measurements were performed with (i) standard iNPWT dressing, (ii) wound gauze diverted through the incision, and (iii) placement of suction drain tube into iNPWT. Results. Due to the modifications of the iNPWT dressing, the vacuum applied by the iNPWT dressing could be transferred into the wound and was not only restricted to superficial layers. More importantly, placement of wound gauzes or suction drain tubes led to complete extraction of wound seroma. The placement of the suction drain tube showed the best combination of increased intrawound pressure as well as seroma evacuation. Conclusion. Addition of a suction drain tube to the iNPWT dressing leads to an improved function of the iNPWT dressing in our ex vivo model.

A comprehensive review of contemporary issues of electronic human resource management (E-HRM)

Information technology (IT) became a vital part of our modern-day activities. In contemporary years, the usage of IT in expediting the human resource management (HRM) activities augmented considerably. E-HRM has the ability to develop managerial competency and influence the role of human resources (HR) as a strategic business partner. E-HRM is essential for firms because of its encouraging effect on staff productivity. Speedy technical modifications revolved E-HRM into a substantial theoretical and professional agenda. This study delivers an exploration into the contemporary level of improvements of the theoretical knowledge connected to E-HRM. Numerous features of E-HRM, specifically descriptions of E-HRM, the academic perceptions around E-HRM, the role of E-HRM, the numerous categories of E-HRM, the requirements for effective E-HRM etc. are scrutinized. It will contribute into HRM literature and regulate the effectiveness of E-HRM and its practices. This research would support the scholars and the practitioners to have the comprehensive portrait of the modern matters linked to E-HRM. The articles concluded by delivering some suggestions for future studies.

Risk identification and technical modifications reduce the incidence of post-cholecystectomy bile leakage: analysis of 5675 laparoscopic cholecystectomies

Purpose The main sources of post-cholecystectomy bile leakage (PCBL) not involving major duct injuries are the cystic duct and subvesical/hepatocystic ducts. Of the many studies on the diagnosis and management of PCBL, few addressed measures to avoid this serious complication. The aim of this study was to examine the causes and mechanisms leading to PCBL and to evaluate the effects of specific preventative strategies. Methods A prospectively maintained database of 5675 consecutive laparoscopic cholecystectomies was analysed. Risk factors for post-cholecystectomy bile leakage were identified and documented and technical modifications and strategies were adopted to prevent this complication. The incidence, causes and management of patients who suffered bile leaks were studied and their preoperative characteristics, operative data and postoperative outcomes were compared with patients where potential risks were identified and PCBL avoided and with the rest of the series. Results Twenty-five patients (0.4%) had PCBL (7 expected and less than half requiring reintervention): 11 from cystic ducts (0.2%), 3 from subvesical ducts (0.05%) and 11 from unconfirmed sources (0.2%). The incidence of cystic duct leakage was significantly lower with ties (0.15%) than with clips (0.7%). Fifty-two percent had difficulty grades IV or V, 36% had empyema or acute cholecystitis and 16% had contracted gallbladders. Twelve patients required 17 reinterventions before PCBL resolved; 7 percutaneous drainage, 6 ERCP and 4 relaparoscopy. The median hospital stay was 17 days with no mortality. Hepatocystic ducts were encountered in 72 patients (1.3%) and were secured with loops (54.2%), ties (25%) or sutures (20.8%) with no PCBL. Eighteen sectoral ducts were identified and secured. Conclusion Ligation of the cystic duct reduces the incidence of PCBL resulting from dislodged endoclips. Careful blunt dissection in the proper anatomical planes avoiding direct or thermal injury to subvesical and sectoral ducts and a policy of actively searching for hepatocystic ducts during gallbladder separation to identify and secure them can reduce bile leakage from such ducts.

Additional fundophrenicopexia, after Nissen fundoplication, reduces postoperative dysphagia and re-operation rate in the long-term follow up

Background Various technical modifications of Nissen fundoplication (NF) that aim to improve patients’ outcomes have been discussed. This study aims to evaluate the effect of division of the short gastric vessels (SGV) and the addition of a standardized fundophrenicopexia on the postoperative outcome after NF. Methods 283 consecutive patients with GERD treated with NF were divided into four groups following consecutive time periods: with division of the SGV and without fundophrenicopexia (group A), with division of the SGV and with fundophrenicopexia (group B), without division of the SGV and with fundophrenicopexia (group C) and without division of the SGV and without fundophrenicopexia (group D). Postoperative contrast swallow, dysphagia scoring, GEDR-HRQL and proton pump inhibitor intake were evaluated. A comparative analysis of patients with division of the SGV and those without (161 A + B vs. 122 C + D), and patients with fundophrenicopexia and those without (78 A vs. 83 B and 49 C vs. 73 D) was performed. Results Fundophrenicopexia reduced postoperative dysphagia rates (0 group C vs. 5 group D, p = 0.021) in patients where the SGV were preserved and reoperation rates (1 group B vs. 7 group A, p = 0.017) in patients where the SGV were divided. There was no significant difference in the postoperative rates of heartburn relief, dysphagia, gas bloating syndrome, interventions, re-fundoplication and the GERD-HRQL score between groups A + B and C + D, respectively. Conclusion Standardized additional fundophrenicopexia in patients undergoing Nissen fundoplication significantly reduces postoperative dysphagia in patients without division of the SGV and reoperation rates in patients with division of the SGV. Division of the SGV has no influence on the postoperative outcome of NF.

E-scooter incidents in Berlin: an evaluation of risk factors and injury patterns

BackgroundE-scooters have emerged as a frequently used vehicle in German cities due to their high availability and easy access. However, investigations about the causes and mechanisms of E-scooter incidents and their trauma-specific consequences are rare.MethodsWe analysed all patients involved in E-scooter incidents from June to December 2019 who presented to four inner-city EDs in Berlin. The prospective data included patient-related and incident-related data, information on injury patterns and therapy, responses in a voluntary questionnaire concerning E-scooter use and general traffic experience.Results248 patients (129 males; median age 29 years (5–81)) were included: 41% were tourists and 4% were children. Most incidents (71%) occurred between July and September 2019, the majority occurring at weekends (58%). The injury pattern was mostly multifocal, affecting the lower (42%) and upper limbs (37%) and the head (40%). Traumatic brain injury was associated with alcohol consumption. Inpatient admission was recorded in 25%, surgery in 23%.ConclusionThis study has defined the incidence of injury related to E-scooter use in a major European city. Stricter laws governing the use of E-scooters, the wearing of helmets and technical modifications to the E-scooter platforms might decrease E-scooter-associated incidents and resulting injuries in the future.Trial registration numberGerman Clinical Trials Registry (DRKS00018061).

A randomized clinical trial of technical modifications of appendix stump closure during laparoscopic appendectomy for uncomplicated acute appendicitis

Background Closure of the appendix stump presents the most critical part of laparoscopic appendectomy. The aim of the present study was to compare the medical outcomes and cost analysis of laparoscopic appendectomy with respect to the different methods of stump closure. Methods This was a prospective randomized clinical trial conducted in a single institution (University Hospital Ostrava) within a 2-year study period. All included patients were randomized into one of three trial arms (endoloop, hem-o-lok clips or endostapler). Results In total, 180 patients (60 patients in each arm) were enrolled into the study. The mean length of hospital stay (3.6 ± 1.7 days) was comparable in all study arms. The shortest operative time was noted in the hem-o-lok subgroup of patients (37.9 ± 12.5 min). Superficial surgical site infection was detected in 4.4% of study patients; deep surgical site infection was noted in 1.7% of the patients. The frequency of surgical site infections was comparable in all study arms (p = 0.7173). The mean direct costs of laparoscopic appendectomy were significantly the lowest in the hem-o-lok subgroup of patients. Laparoscopic appendectomy is not a profit-making procedure in our institution (mean profit of made from the study patients was—104.3 ± 579.2 Euro). Closure of the appendix stump by means of endostapler presents the most expensive and the highest loss-incurring technique (p = 0.0072). Conclusions The present study indicates that all technical modifications of appendix stump closure are comparable with regards to postoperative complications. The stapler technique is significantly the most expensive. We concluded that hem-o-lok clips have the potential for becoming the preferred method of securing the appendix base during laparoscopic appendectomy.
