Long-term persistence of carrier-bound fibrin sealant (TachoSil®) following abdominal surgery: a decade-long follow-up study.

This study analyzed the long-term effects of carrier-bound fibrin sealant (CBFS) following abdominal surgery by tracking patients for years post-application. From 2006 to 2022, patients who underwent this procedure were contacted via telephone. Those who died due to underlying diseases, natural causes, or refused the check-up were excluded from the study. After 11 years of follow-up, CBFS was observed in different forms on computed tomography scans in four patients. Our findings indicate that CBFS can persist for years after the procedure. While we cannot confirm any secondary effects, it appears that CBFS sponges are not resorbed within 12 weeks and can remain for many years post-implantation.

The 2023 WSES guidelines on the management of trauma in elderly and frail patients.

BACKGROUND: The trauma mortality rate is higher in the elderly compared with younger patients. Ageing is associated with physiological changes in multiple systems and correlated with frailty. Frailty is a risk factor for mortality in elderly trauma patients. We aim to provide evidence-based guidelines for the management of geriatric trauma patients to improve it and reduce futile procedures. METHODS: Six working groups of expert acute care and trauma surgeons reviewed extensively the literature according to the topic and the PICO question assigned. Statements and recommendations were assessed according to the GRADE methodology and approved by a consensus of experts in the field at the 10th international congress of the WSES in 2023. RESULTS: The management of elderly trauma patients requires knowledge of ageing physiology, a focused triage, including drug history, frailty assessment, nutritional status, and early activation of trauma protocol to improve outcomes. Acute trauma pain in the elderly has to be managed in a multimodal analgesic approach, to avoid side effects of opioid use. Antibiotic prophylaxis is recommended in penetrating (abdominal, thoracic) trauma, in severely burned and in open fractures elderly patients to decrease septic complications. Antibiotics are not recommended in blunt trauma in the absence of signs of sepsis and septic shock. Venous thromboembolism prophylaxis with LMWH or UFH should be administrated as soon as possible in high and moderate-risk elderly trauma patients according to the renal function, weight of the patient and bleeding risk. A palliative care team should be involved as soon as possible to discuss the end of life in a multidisciplinary approach considering the patient's directives, family feelings and representatives' desires, and all decisions should be shared. CONCLUSIONS: The management of elderly trauma patients requires knowledge of ageing physiology, a focused triage based on assessing frailty and early activation of trauma protocol to improve outcomes. Geriatric Intensive Care Units are needed to care for elderly and frail trauma patients in a multidisciplinary approach to decrease mortality and improve outcomes.

Acute cholecystitis: how to avoid subtotal cholecystectomy-preliminary results.

BACKGROUND: The aim of this manuscript is to illustrate a new method permitting safe cholecystectomy in terms of complications with respect to the common bile duct (CBD). METHODS: The core of this new technique is identification of the continuity of the cystic duct with the infundibulum. The cystic duct can be identified between the inner gallbladder wall and inflamed outer wall. RESULTS: In the last 2 years, from January 2019 until December 2021, 3 patients have been treated with the reported technique without complications. CONCLUSIONS: Among the various cholecystectomy procedures, this is a new approach that ensures the safety of the structures of Calot's triangle while providing the advantages gained from total removal of the gallbladder.

Cesena guidelines: WSES consensus statement on laparoscopic-first approach to general surgery emergencies and abdominal trauma.

BACKGROUND: Laparoscopy is widely adopted across nearly all surgical subspecialties in the elective setting. Initially finding indication in minor abdominal emergencies, it has gradually become the standard approach in the majority of elective general surgery procedures. Despite many technological advances and increasing acceptance, the laparoscopic approach remains underutilized in emergency general surgery and in abdominal trauma. Emergency laparotomy continues to carry a high morbidity and mortality. In recent years, there has been a growing interest from emergency and trauma surgeons in adopting minimally invasive surgery approaches in the acute surgical setting. The present position paper, supported by the World Society of Emergency Surgery (WSES), aims to provide a review of the literature to reach a consensus on the indications and benefits of a laparoscopic-first approach in patients requiring emergency abdominal surgery for general surgery emergencies or abdominal trauma. METHODS: This position paper was developed according to the WSES methodology. A steering committee performed the literature review and drafted the position paper. An international panel of 54 experts then critically revised the manuscript and discussed it in detail, to develop a consensus on a position statement. RESULTS: A total of 323 studies (systematic review and meta-analysis, randomized clinical trial, retrospective comparative cohort studies, case series) have been selected from an initial pool of 7409 studies. Evidence demonstrates several benefits of the laparoscopic approach in stable patients undergoing emergency abdominal surgery for general surgical emergencies or abdominal trauma. The selection of a stable patient seems to be of paramount importance for a safe adoption of a laparoscopic approach. In hemodynamically stable patients, the laparoscopic approach was found to be safe, feasible and effective as a therapeutic tool or helpful to identify further management steps and needs, resulting in improved outcomes, regardless of conversion. Appropriate patient selection, surgeon experience and rigorous minimally invasive surgical training, remain crucial factors to increase the adoption of laparoscopy in emergency general surgery and abdominal trauma. CONCLUSIONS: The WSES expert panel suggests laparoscopy as the first approach for stable patients undergoing emergency abdominal surgery for general surgery emergencies and abdominal trauma.

Phantosmia May Predict Long-Term Measurable Olfactory Dysfunction After COVID-19.

OBJECTIVES: Persistent olfactory dysfunction (OD) after 6 months caused by SARS-CoV-2 infection has been reported with a variable prevalence worldwide. This study aimed to determine the prevalence of long-term OD and identify predisposing factors. METHODS: A prospective cohort study was conducted on 100 adults with COVID-19. Olfactory function was assessed with the University of Pennsylvania Smell Identification Test and a symptom survey at the onset of disease and 30 days later. Patients with persistent quantitative OD at the second assessment were reevaluated after 1 year. Demographic variables, symptoms, and the degree of smell loss were analyzed. RESULTS: Participants included 100 patients. The mean age was 42.2 ± 15.6 years, 55 (55%) were female, and 56 (56%) were outpatients. Baseline smell loss was identified in 75/100 (75%) patients, decreasing to 39/95 (40%) after 1 month, and persisting in 29 patients after 1 year. Phantosmia at baseline was the only risk factor identified for persistent OD after 1 year (relative risk 2.51; 95% confidence interval 1.53-4.12; p < 0.001). Regardless of the outcome in smell function, a significant decline in olfaction was associated with the presence of phantosmia at 1 month (ß = -12.39; 95% CI -19.82 to -4.95; p < 0.01). CONCLUSIONS: SARS-CoV-2 (2019-2020 variants) produced a highly frequent OD that persisted in 29% of the patients after 1 year. The presence of phantosmia at baseline and 1 month was associated with a worse evolution, but phantosmia may interfere with the performance in an identification smell test. A longer follow-up is required in these patients. LEVEL OF EVIDENCE: 2 Laryngoscope, 132:2445-2452, 2022.

High prevalence of SARS-CoV-2 detection and prolonged viral shedding in stools: A systematic review and cohort study.

OBJECTIVES: To: 1. Describe the frequency of viral RNA detection in stools in a cohort of patients infected with SARS-CoV-2, and 2. Perform a systematic review to assess the clearance time in stools of SARS-CoV-2. METHODS: We conducted a prospective cohort study in two centers between March and May 2020. We included SARS-CoV-2 infected patients of any age and severity. We collected seriated nasopharyngeal swabs and stool samples to detect SARS-CoV-2. After, we performed a systematic review of the prevalence and clearance of SARS-CoV-2 in stools (PROSPERO-ID: CRD42020192490). We estimated prevalence using a random-effects model. We assessed clearance time by using Kaplan-Meier curves. RESULTS: We included 32 patients; mean age was 43.7±17.7 years, 43.8% were female, and 40.6% reported gastrointestinal symptoms. Twenty-five percent (8/32) of patients had detectable viral RNA in stools. The median clearance time in stools of the cohort was 11[10-15] days. Systematic review included 30 studies (1392 patients) with stool samples. Six studies were performed in children and 55% were male. The pooled prevalence of viral detection in stools was 34.6% (twenty-four studies, 1393 patients; 95%CI:25.4-45.1); heterogeneity was high (I2:91.2%, Q:208.6; p≤0.001). A meta-regression demonstrates an association between female-gender and lower presence in stools (p=0.004). The median clearance time in stools was 22 days (nineteen studies, 140 patients; 95%CI:19-25). After 34 days, 19.9% (95%CI:11.3-29.7) of patients have a persistent detection in stools. CONCLUSIONS: Detection of SARS-CoV-2 in stools is a frequent finding. The clearance of SARS-CoV-2 in stools is prolonged and it takes longer than nasopharyngeal secretions.

Subtotal cholecystectomy for difficult acute cholecystitis: how to finalize safely by laparoscopy-a systematic review.

BACKGROUND: Aim of this study was to clarify the best laparoscopic subtotal cholecystectomy (LSTC) technique for finalizing a difficult cholecystectomy. PATIENTS AND METHODS: A review was performed (1987-2021) searching "difficulty cholecystectomy" AND/OR "subtotal cholecystectomy". The LSTC techniques considered were as follows: type A, leaving posterior wall attached to the liver and the remainder of the gallbladder stump open; type B, like type A but with the stump closed; type C, resection of both the anterior and posterior gallbladder walls and the stump closed; type D, like type C but with the stump open. Morbidity (including mortality) was analysed with Dindo-Clavien classification. RESULTS: Nineteen articles were included. Of the 13,340 patients screened, 678 (8.2%) had cholecystectomy finalized by LSTC: 346 patients (51.0%) had type A LSTC, 134 patients (19.8%) had type B LSTC, 198 patients (29.2%) had type C LSTC, and 198 patients (0%) had type D LSTC. Bile leakage was found in 83 patients (12.2%), and recorded in 58 patients (69.9%) treated by type A. Twenty-three patients (3.4%) developed a subhepatic collection, 19 of whom (82.6%) were treated by type A. Other complications were reported in 72 patients (10.6%). The Dindo-Clavien classification was four for grade I, 27 for grade II, 126 for grade IIIa, 18 for grade IIIb, zero for grade IV and three for grade V. CONCLUSION: In the case of LSTC, closure of the gallbladder stump represents the best method to avoid complications. Careful exploration of the gallbladder stump is mandatory, washing the abdominal cavity and leaving drainage.

Forty years after the first totally implantable venous access device (TIVAD) implant: the pure surgical cut-down technique only avoids immediate complications that can be fatal.

AIM: Even though TIVADs have been implanted for a long time, immediate complications are still occurring. The aim of this work was to review different techniques of placing TIVAD implants to evaluate the aetiology of immediate complications. METHODS: A systematic literature review was performed using the PubMed, Cochrane and Google Scholar databases in accordance with the PRISMA guidelines. The patient numbers, number of implanted devices, specialists involved, implant techniques, implant sites and immediate complication onsets were studied. RESULTS: Of the 1256 manuscripts reviewed, 36 were eligible for inclusion in the study, for a total of 17,388 patients with equivalent TIVAD implantation. A total of 2745 patients (15.8%) were treated with a surgical technique and 14,643 patients (84.2%) were treated with a percutaneous technique. Of the 2745 devices (15.8%) implanted by a surgical technique, 1721 devices (62.7%) were placed in the cephalic vein (CFV). Of the 14,643 implants (84.2%) placed with a percutaneous technique, 5784 devices (39.5%) were placed in the internal jugular vein (IJV), and 5321 devices (36.3%) were placed in the subclavian vein (SCV). The number of immediate complications in patients undergoing surgical techniques was 32 (1.2%) HMMs. In patients treated with a percutaneous technique, the number of total complications were 333 (2.8%): 71 PNX (0.5%), 2 HMT (0.01%), 175 accidental artery punctures AAP (1.2%) and 85 HMM (0.6%). No mortality was reported with either technique. CONCLUSION: The percutaneous approach is currently the most commonly used technique to implant a TIVAD, but despite specialist's best efforts, immediate complications are still occurring. Surgical cut-down, 40 years after the first implant, is still the only technique that can avoid all of the immediate complications that can be fatal.

Viral shedding dynamics reveals sputum as a reliable and cost-saving specimen for SARS-CoV-2 diagnosis within the first 10 days since symptom onset: A prospective cohort study.

BACKGROUND: Coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome virus (SARS-CoV-2) is challenging global public health, due to an increasing demand for testing and the shortage of diagnostic supplies. Nasopharyngeal swab (NPS) is considered the optimal sample for SARS-CoV2 diagnosis and sputum (SPT) has been proposed as an economic alternative. However, the temporal concordance of diagnosis in NPS and SPT has not been addressed. METHODS: Through a longitudinal study we compared the shedding dynamics of SARS-CoV-2 RNA evaluated by RT-qPCR in serially collected SPT and NPS obtained from 82 ambulatory and hospitalized patients during acute infection and convalescence. The concordance during the follow-up and cost analysis between both collected specimens was evaluated. FINDINGS: We analyzed 379 samples, 177 NPS and 202 SPT. The highest proportion of positive samples was detected within the first 15 days after the symptoms onset. The median time of positivity was higher for NPS (median= 25 days) than SPT (median= 21 days). There was no significant difference in the median RT-qPCR CT values between both sample types. The temporal categorization of matched-paired samples indicated substantial correlation (r=0.6023) and substantial agreement (87.23%) during the first ten days since symptoms onset (kappa = 0.697). A cost analysis demonstrated a significant saving when the SPT specimen was used. INTERPRETATION: Sputum is a feasible and cost-saving alternative to NPS, providing an equivalent value for the detection and follow-up of SARS-CoV-2 RNA.
