Robotic transversus abdominis release (TAR) for ventral hernia repairs is associated with low surgical site occurrence rates and length of stay despite increasing modifiable comorbidities

PurposeModifiable comorbidities (MCMs) have previously been shown to complicate postoperative wound healing occasionally leading to surgeon hesitancy to repair ventral hernias prior to preoperative optimization of comorbidities. This study describes the effects of MCMs on surgical site occurrences (SSOs) and hospital length of stay (LOS) following robotic transversus abdominis release (TAR) with poly-4-hydroxybutyrate (P4HB) resorbable biosynthetic mesh retromuscular sublay for ventral hernia repair in patients who had not undergone preoperative optimization.MethodsA single-surgeon retrospective review was performed for patients who underwent the robotic TAR procedure with P4HB mesh between January 2015 and May 2022. Patients were stratified by the amount of MCMs present: 0, 1, or 2 + . MCMs included obesity, diabetes, and current tobacco use. Patient data was analyzed for the first 60 days following their operation. Primary outcomes included 60-day SSO rates and hospital LOS.ResultsThree hundred and thirty-four subjects met the inclusion criteria for SSO and prolonged LOS analysis. 16.8% had no MCM, 56.1% had 1 MCM, and 27% had 2 + MCMs. No significant difference in SSO was seen between the 3 groups; however, having 2 + MCMs was significantly associated with increased odds of SSO (odds ratio 3.25, P = .019). When the groups were broken down, only having a history of diabetes plus obesity was associated with significantly increased odds of SSO (odds ratio 3.54, P = .02). No group showed significantly increased odds of prolonged LOS.Conclusion2 + MCMs significantly increase the odds of SSO, specifically in patients who have a history of diabetes and obesity. However, the presence of any number of MCMs was not associated with increased odds of prolonged LOS.

Soft Tissue Reconstruction After Sacral Neoplasm Resection: The University of California San Francisco Experience.

Resection of sacral neoplasms such as chordoma and chondrosarcoma with subsequent reconstruction of large soft tissue defects is a complex multidisciplinary process. Radiotherapy and prior abdominal surgery play a role in reconstructive planning; however, there is no consensus on how to maximize outcomes. In this study, we present our institution's experience with the reconstructive surgical management of this unique patient population. We conducted a retrospective review of patients who underwent reconstruction after resection of primary or recurrent pelvic chordoma or chondrosarcoma between 2002 and 2019. Surgical details, hospital stay, and postoperative outcomes were assessed. Patients were divided into 3 groups for comparison based on reconstruction technique: gluteal-based flaps, vertical rectus abdominus myocutaneous (VRAM) flaps, and locoregional fasciocutaneous flaps. Twenty-eight patients (17 males, 11 females), with mean age of 62 years (range, 34-86 years), were reviewed. Twenty-two patients (78.6%) received gluteal-based flaps, 3 patients (10.7%) received VRAM flaps, and 3 patients (10.7%) were reconstructed with locoregional fasciocutaneous flaps. Patients in the VRAM group were significantly more likely to have undergone total sacrectomy (P < 0.01) in a 2-stage operation (P < 0.01) compared with patients in the other 2 groups. Patients in the VRAM group also had a significantly greater average number of reoperations (2 ± 3.5, P = 0.04) and length of stay (29.7 ± 20.4 days, P = 0.01) compared with the 2 other groups. The overall minor and major wound complication rates were 17.9% and 42.9%, respectively, with 17.9% of patients experiencing at least 1 infection or seroma. There was no association between prior abdominal surgery, surgical stages, or radiation therapy and an increased risk of wound complications. Vertical rectus abdominus myocutaneous flaps are a more suitable option for patients with larger defects after total sacrectomy via 2-staged anteroposterior resections, whereas gluteal myocutaneous flaps are effective options for posterior-only resections. For patients with small- to moderate-sized defects, local fasciocutaneous flaps are a less invasive and effective option. Paraspinous flaps may be used in combination with other techniques to provide additional bulk and coverage for especially long postresection wounds. Furthermore, mesh is a useful adjunct for any reconstruction aimed at protecting against intra-abdominal complications.

The Impact of Surgical Wait Time and Hospital Stay on the Incidence of Burn Wound Infection and Related Complications at a Single Tertiary Hospital Centre: A 10-Year Experience

Introduction: Admitted patients with burn injuries require prompt treatment and shorter hospital stays to avoid hospital-acquired infections and associated complications. This study aimed to determine the impact of time to the first surgery, and total length of hospital stay on the incidence of BWI and associated complications in adult patients with moderate burn injuries at a single tertiary hospital burn center. Methods: A retrospective chart review identified burn patients admitted to the Burn Unit between January 2011 and January 2021. The incidences of BWI and complications were documented. Univariate logistic regressions were performed, with significance set at P &lt; .05. Results: A total of 171 patients were included in the study. The mean age was 50.8 years (range, 94-18 years), with 64 (37.4%) females. The mean wait time for surgery and total hospital stay was 2.6 days (SD = 2.5; 1-15 days) and 18.6 days (SD = 16.0; 1-125 days), respectively. Precisely, 47 patients (27.5%) were associated with positive burn wound cultures, with 23 patients (13.5%) experiencing clinical burn wound complications. Wait time to surgery did not significantly impact the incidence of BWI (OR = 0.97, P = .72) or related complications (OR = 0.97, P = .61). Total hospital stay was significantly associated with the incidence of BWI (OR = 1.05, P &lt; .001) and related complications (OR = 1.02, P = .03). Conclusions: Delay to surgery may not be a significant risk factor of BWI and related complications in patients with burn injuries. Half of positive burn wound cultures are associated with objective clinical infection and subsequent complications. However, total hospital stay may be clinically important.

The Effect of Obesity on Surgical Outcomes in General Surgery Patients: A Systematic Review of 1,680,694 patients

The study examined the impact of obesity on general surgery patients, analyzing eleven studies with 1,680,694 patients. Results showed that obesity increases postoperative wound infection risk, blood loss, and recovery times. However, prospective studies found no increase in surgical complications or hospitalization expenses. Obesity may protect against venous thromboembolism and death, but post-operative complications in obese patients undergoing general surgical procedures remain controversial due to metabolic, pharmacologic, and systemic illnesses. Obesity increases surgical duration and SSIs, potentially increasing immediate complications.

Robotic intersphincteric resection of low rectal cancer versus laparoscopic intersphincteric resection of low rectal cancer

This systematic review evaluated and compared the two currently available intersphincteric resection techniques (robotic and laparoscopic intersphincteric resection) for low rectal cancer, with the final aim of comparing associated factors between the two techniques. The assessed factors included surgical duration, hospital stay, complications, overall survival, local recurrence, and low anterior resection syndrome (LARS). A literature search of the search engines “PubMed”, “SCOPUS”, and “Web of Science” was conducted, with a time interval set between 2015 and 2023. The initial search yielded 57 studies, of which 10 met the inclusion and exclusion criteria. Hence, data was extracted from only these 10 studies. The average reported robotic surgery time varied between 197 and 472 mins, while the laparoscopic surgery time varied between 240 and 325 mins. Conversely, the overall survival and local recurrence rates were 89.7% and 6.7% for robotic and 87.9% and 6.2% for laparoscopic resection, respectively. In addition, complications were reported in 16.5% and 18.2% of robotic and laparoscopic resection cases, respectively. This systematic review showed that although the surgery duration is longer in robotic resection compared to laparoscopic resection, the former technique is associated with lower rates of complications and local recurrence, and improved overall survival. In addition, few studies have reported on the prevalence of LARS; therefore, we recommend that this field be studied and included in the reported data of the upcoming studies to allow more conclusive evidence regarding prevalence of LARS among the two groups of intersphincteric resections.

Percutaneous nephrolithotomy or flexible ureteral lithotripsy, which one is better for patients with upper ureteral calculi of 1.5–2.0 cm in diameter

PurposeFirst research to evaluate the clinical efficacy and safety of flexible ureteral lithotripsy (FURSL) and percutaneous nephrolithotomy (PCNL) in the treatment of the upper ureteral stone is between 1.5 cm and 2.0 cm in diameter since there is no consensus with such ureteral stone yet.MethodsFrom December 2018 to October 2022, 104 patients with calculi in the upper ureter received percutaneous nephrolithotomy (PCNL)or flexible ureteroscopic lithotripsy (FURSL) in our institution. The clinical data of the patients in the two groups were retrospectively searched. Stone removal rate, operation time, blood loss, postoperative pain score, postoperative inflammatory factor, postoperative complication rates and ureteral obstruction three months after the operation were compared between the two groups.ResultsA total of 104 patients were included in the study. The stone clearance rate and the secondary surgery rate were 88.89% and 7.41% in the FURSL group, the figures were 97.96% and 2.0% in the PCNL group (p = 0.067, 0.497). Regarding ureteral obstruction three months after the operation, there were 2 patients in FURSL group and 0 patients in PCNL group(p = 0.497).Compared to patients in FURSL group, patients in the PCNL group had shorter operation time(PCNL 71.81 ± 18.94 min vs. FURSL 86.80 ± 22.49 min, p = 0.0004), fewer complications(PCNL 20.37% vs. FURSL 6.12%), and lower postoperative inflammatory factor(p = 0.0004), yet they got more hemoglobin drop (PCNL 13.14 ± 9.81 g/L vs. FURSL 4.77 ± 3.55 g/L, p < 0.0001), higher postoperative pain scores(p = 0.0017) in the first three postoperative days and longer hospital stay (PCNL 4.96 ± 1.21 days vs. FURSL 3.60 ± 0.83 days).ConclusionBoth FURSL and PCNL were effective methods for treating upper ureteral stones of 1.5–2.0 cm in diameter given the extremely high stone clearance rate and a very low secondary surgery rate, as long as rare ureteral obstruction in medium-long term observation. Additionally, FURSL can effectively reduce surgical bleeding, postoperative pain, and hospital stay, while PCNL can decrease operation time, the risk of infection, and complications. Therefore, doctors could select suitable surgical treatment for those patients depending on their different clinical situations based on these findings.

Results of patient survival after surgical interventions for complicated forms of colon cancer performed in general surgical hospitals

The aim of the study: to evaluate the 1- and 3-year survival of patients operated for complicated forms of colon cancer (СC) in general surgical hospital. Materials and methods. The study group included 71 (100 %) patients with complicated forms of СС. Acute intestinal obstruction was detected in 49 (69.1 %) patients, tumor perforation – in 13 (18.3 %), acute colonic bleeding – in 3 (4.2 %) patients, a combination of acute intestinal obstruction with tumor perforation – in 4 (5.6 %) and intestinal obstruction with bleeding – in 2 (2.8 %) operated patients. Radical operations were performed in 48 (67.6 %) patients, palliative operations – in 18 (25.4 %), symptomatic operations – in 5 (7.0 %) patients. II stage of the disease was diagnosed in 15 (21.1 %), III stage – in 32 (45.1 %), IV stage – in 24 (33.8 %) operated patients. 19 (30.2 %) patients underwent specific chemotherapy after surgery. Results. Among patients with the II stage of the oncological process 1-year survival was 76.9 ± 11.7 %, 3-year – 53.8 ± 13.8 %; with stage III, 1-year survival was 65.6 ± 8.4 %, 3-year – 50.0 ± 8.8 %; in persons with IV stage of СC – 29.2 ± 9.3 % and 8.3 ± 2.6 % respectively (χ2 = 21.8, p = 0.0001). Among male patients, 1-year survival was 51.4 ± 8.5 %, 3-year – 31.4 ± 7.9 %; women – 61.1 ± 8.1 % and 44.4 ± 8.3 %, respectively (χ2 = 2.3, p = 0.1302). Better indicators were found in the case of cancer of the left sections of the large intestine than the right sections – the 1-year survival rate was 60.4 ± 7.1 % and 43.5 ± 10.3 % respectively; 3-year – 39.6 ± 7.1 % and 30.4 ± 9.6 % (χ2 = 0.74, p = 0.3906). Conclusions. The conducted analysis indicates a clear dependence of the survival results on the stage of the disease, gender and localization of the tumor process.

Post-discharge Mental Healthcare and Emergency General Surgery Readmission for Patients with Serious Mental Illness.

To determine the association between post-discharge mental healthcare and odds of readmission after emergency general surgery (EGS) hospitalization for patients with serious mental illness (SMI). A mental health visit (MHV) after medical hospitalization is associated with decreased readmissions for patients with SMI. The impact of a MHV after surgical hospitalization is unknown. Using Medicare claims, we performed a retrospective cohort study of hospitalized EGS patients with SMI aged >65.5 (2016-2018). EGS included colorectal, general abdominal, hepatopancreatobiliary, hernia, intestinal obstruction, resuscitation, and upper gastrointestinal conditions. SMI was defined as schizophrenia spectrum, mood, or anxiety disorders. The exposure was MHV within 30 days of discharge. The primary outcome was 30-day readmission. Secondary outcomes included emergency department presentation and psychiatric admission. Inverse probability weighting was used to evaluated outcomes. Of 88,092 analyzed patients, 11,755 (13.3%) had a MHV within 30 days of discharge. 23,696 (26.9%) of patients were managed operatively, 64,395 (73.1%) non-operatively. After adjustment for potential confounders, patients with a post-discharge MHV had lower odds of acute care readmission than patients without a MHV in both operative (OR 0.60; 95% CI: [0.40-0.90]) and non-operative (OR 0.67; 95% CI [0.53-0.84]) cohorts. There was no association between post-discharge MHV and ED presentation or psychiatric admission in the operative or non-operative groups. Post-discharge MHV after EGS hospitalization was associated with decreased odds of readmission for patients with SMI managed operatively and nonoperatively. In older EGS patients with SMI, coordination of MHVs may be a mechanism to reduce readmission disparities.

A prescription for efficiency: optimizing the surgical item inventory management practices in a healthcare facility

PurposeThe primary objective of this article is to examine current procurement, inventory control and management practices in modern healthcare, with a particular focus on the procurement and management of surgical supplies in a prominent public, highly specialized healthcare sector.Design/methodology/approachThis study was conducted in three phases. In Phase 1, the study team interacted with various hospital management stakeholders, including the surgical hospital store, examined the current procurement process and identified challenges. Phase 2 focused on selecting items for a detailed study and collected the qualitative and quantitative details of the store department of the healthcare sector chosen. A detailed study analyzed revenue, output/demand, inventory levels, etc. In Phase 3, a decision-making framework is proposed, and inventory control systems are redesigned and demonstrated for the selected items.FindingsIt was observed that the demand for many surgical items had increased significantly over the years due to an increase in disposable/disposable items, while inventories fluctuated widely. Maximum inventory levels varied between 50 and 75%. Storage and availability were important issues for the hospital. It is assumed the hospital adopts the proposed inventory control system. In this case, the benefits can be a saving of 62% of the maximum inventory, 20% of the average stock in the system and optimal use of storage space, improving the performance and productivity of the hospital.Research limitations/implicationsThis study can help the healthcare sector administration to develop better systems for the procurement and delivery of common surgical items and efficient resource allocation. It can help provide adequate training to store staff. This study can help improve management/procurement policies, ordering and delivery systems, better service levels, and inventory control of items in the hospital business context. This study can serve as a pilot study to further investigate the overall hospital operations.Practical implicationsThis study can help the healthcare sector administration develop better systems for procuring and delivering common surgical items and efficient resource allocation.

Impact of occupational stress on nursing professionals who provide hospital care

Introduction: One of the factors such as excessive working hours in nursing professionals poses a risk to their professional health, likely affecting the quality and productivity of the service provided. Objective: To determine the impact of job stress on part-time nursing professionals at the Technical University of Ambato. Methodology: A descriptive, non-experimental cross-sectional study was conducted. A survey was administered using the Spanish version of the Nursing Stress Scale (NSS) during July 2023. All part-time nursing staff working at the Technical University of Ambato as clinical instructors (n=50) were included. Data such as age and hospital work service were considered. Full-time nursing staff were excluded. Results: The surveyed nursing professionals predominated in services such as Operating Room 18% (n=9), Emergency 12% (n=6), Neonatology 12% (n=6), and Surgical Hospitalization 10% (n=5), with an average age of 38.6 years (Min 24 - Max 59). Regarding the determination of job stress based on evaluated stressors, scores characterized as "sometimes" predominated with 54% (n=27), followed by "never" with 26% (n=13), "frequently" with 16% (n=8), and finally "very frequently" with 4% (n=2). Conclusion: Stress related to disagreement with a patient's treatment was found to have a significant impact on the job stress of nursing professionals.

Modern concept of treatment of patients with ventral hernias

INTRODUCTION. The relevance of treating patients with hernias of the anterior abdominal wall is beyond doubt, since the incidence of the disease is on average 5 people per 1000, and hernioplasty itself is one of the most common operations in a general surgical hospital. However, the relapse rate remains quite high. There remains a debate about the choice of surgical option; the issues of prevention and treatment of pain syndrome, as well as tactics for managing patients with a complicated postoperative period, remain unresolved.The OBJECTIVE was to evaluate the effectiveness of the modern concept of treating patients with ventral hernias and to substantiate the principles for choosing a hernioplasty technique.METHODS AND MATERIALS. The study is based on the results of treatment of 1938 patients operated on at the Faculty Surgery Clinic named after S.P. Fedorov Military Medical Academy in the period from 2015 to 2022. Both open and endovideosurgical options for surgical interventions were performed for isolated umbilical hernias or in combination with diastasis of the rectus muscles, hernias of the white line of the abdomen, inguinal and postoperative hernias, including reduction of the volume of the abdominal cavity.RESULTS. During the study, an algorithm for the treatment of patients with ventral hernias was developed, various options for perioperative pain relief were proposed, and the tactics for treating infectious and purulent complications were substantiated.CONCLUSION. A specialized surgical hospital must perform all possible options for both traditional and endovideosurgical hernioplasty, use innovative options for pain relief in the perioperative period, and apply modern methods for diagnosing and treating postoperative complications in order to provide personalized medical care.

Comparison of laser ablation and Karidakis surgery for treating epithelial coccygeal passages

BACKGROUND: Laser ablation is a technique which was originally used to treat various cystic and fistulous structures. Due to promising results, surgeons began to use diode lasers to treat pilonidal cysts. The authors developed their own technique of ultrasonic-guided laser ablation in patients with the discussed pathology. AIM: To compare outcomes after laser ablation and Karidakis surgery for treating pilonidal cysts. METHODS: A prospective non-randomized comparative study was performed. Outcomes of surgical interventions were analyzed in 71 patient with pilonidal disease: 24 patients were operated with laser obliteration technique and 47 — with Karidakis technique. The researchers compared: time of wound healing and number of recurrences, complications, length of hospital stay and duration of postoperative pain. RESULTS: Mean operative time in the laser group was 26.45±5.41 min (20–35 min), while in the Karidakis group — 58.63±7.42 min (50–75 min). In the laser group, primary healing was registered in 23 out of 24 patients (95.8%) with an overall complication rate 20.83%. In each group, there were registered two cases with relapses after discharge. The obtained clinical results, in general, were comparable to those in the world literature. However, the quality of life of patients after laser treatment was significantly better than after traditional surgical intervention which is confirmed by less hospital stay up to 5–7 bed-days; by less surgical time, in average, 25 minutes; faster recovery — within one week after surgery; faster return to everyday life, as well as less pain syndrome in the postoperative period. CONCLUSION: Laser ablation of the coccygeal tract is comparable to Karidakis surgery in terms of wound healing and recurrences, but it gives better results in terms of surgical time, hospital stay and postoperative pain.

Surgeon Perceptions of Performing Transforaminal Lumbar Interbody Fusion in an Ambulatory Surgical Center vs Hospital Setting in the Elderly Population: Results of a Surgeon Survey.

There is an increasing acceptance of conducting minimally invasive transforaminal lumbar interbody fusion (TLIF) in ambulatory surgical centers (ASCs). The Centers for Medicare and Medicaid Services (CMS) introduced the Hospitals Without Walls (HWW) program in March 2020. This program granted hospitals regulatory flexibility to offer services and procedures in nontraditional locations, including ASCs. However, implementation hurdles persist. A survey was sent to 235 surgeons regarding the use of ASCs for performing TLIF surgeries on elderly patients. Multiple-choice questions covering various aspects of TLIF practice preferences, including surgical indications, decision factors for choosing ASCs over hospitals, implementation hurdles, reimbursement concerns, staffing issues, and the impact of CMS rules and regulations on TLIF in ASCs, particularly concerning physician ownership and self-referral conflicts governed by the Stark law, were asked. The survey completion rate was 25.8% (Figure 1). The most common surgical indications for TLIF in ASCs were spondylolisthesis (80%), spinal stenosis (62.5%), and low back pain (47.5%). Most surgeons (78%) believed TLIF could be safely performed in ASCs. Streamlined workflow, lower infection rates, and cost-effectiveness were advantages listed by 58.5% of surgeons. Patient's medical history (75.8%), followed by ASC resources and capabilities (61%) and surgeon preference (61%), were relevant factors. Higher efficiencies at ASCs (14.6%), contractual issues (9.8%), and ownership issues (7.3%) were less relevant to surgeons. About 65.9% of surgeons reported lower reimbursement in ASCs, and 43.9% said it was an implementation hurdle. Lower direct costs were reported by 53.7% of surgeons. Other hurdles included a lack of trained staff (24.4%), inadequate staffing (22.0%), cost overruns (26.8%), high Joint Commission or the Accreditation Association for Ambulatory Health Care credentialing costs, and surgeons feeling uncomfortable performing TLIF in ASCs (22.0%). Only 17.1% listed medical problems as a reason their patient was considered unsuitable for the ASC environment. A majority (53.7%) stated that their ASCs complied with strict Stark requirements by disclosing physician ownership interests. However, 22% of surgeons reported self-referrals under the "In-Office Ancillary Services Exception" allowed by the Stark law. Our survey data show that surgeons' perceptions of current CMS rules and regulations may hinder the transition into the ASC setting because they think the reimbursement is too low and the regulatory burden is too high. ASCs have disproportionally higher initial acquisition and ongoing costs related to staff training and maintenance of the TLIF technology that CMS should consider when determining the appropriate financial remuneration for these complex procedures. ASC offers a viable and attractive option for their TLIF procedure with the advantage of same-day discharge and at-home recovery.

Территориальные особенности оказания экстренной хирургической помощи сельскому населению (на примере Республики Северная Осетия-Алания).

The need to modernize healthcare dictates the study of healthcare organization at all levels. Special attention is paid to the territorial accessibility of medical care, including to the rural population, which differs in many specific features. The purpose of the study: to study the territorial features of providing emergency surgical care to the rural population, taking into account the number, density of population settlement, road infrastructure, and transport security in the Republic of North Ossetia-Alania. Research methods. Analytical and statistical research methods were used. The performance indicators of surgical departments of rural district hospitals for 2019–2022 have been studied. The analysis of the obtained data was carried out by the method of their structural description according to the selected main characteristics affecting territorial accessibility. Results. The Republic of Ossetia-Alania is characterized by high density and compactness of population settlement in rural areas. The creation of a modern transport infrastructure ensures the territorial accessibility of medical care. The republic has a fairly high level of provision with surgeons (2,53 per 10 thousand population) and a surgical bed fund (4,7 per 10 thousand population). However, there is a need to increase the efficiency of using the bed stock of rural surgical hospitals. The organization of surgical care in the republic in 2020–2021 was extremely negatively affected by the pandemic of coronavirus infection COVID‑19. The reduction of surgical and anesthesiological teams, beds and the volume of planned care due to the opening of additional infectious diseases hospitals has reduced the availability and quality of emergency surgical care. In rural district surgical departments, the bed function decreased from 283 days in 2019 to 243 days in 2020, and surgical activity up to 38,8%. In 2020–2021, planned medical care in the «surgery» profile has significantly decreased. The share of emergency hospitalizations increased to 79,7%. Negative trends in the growth of emergency hospitalization for surgical beds led to an increase in the hospital mortality rate compared to 2019 from 0,6% to 3,1% in 2021. The postoperative mortality rate has increased by more than 5 times. Our data correlate with similar trends of 33% increase in hospital mortality in the Russian Federation during the pandemic. Due to the creation of modern road transport infrastructure in the republic, high availability of surgical beds and surgeons, there is a potential to improve the quality indicators of rural surgical hospitals by improving the material and technical equipment and qualifications of surgical personnel.

Evaluation of venous thromboembolism risk assessment models for hospital inpatients: the VTEAM evidence synthesis.

Pharmacological prophylaxis during hospital admission can reduce the risk of acquired blood clots (venous thromboembolism) but may cause complications, such as bleeding. Using a risk assessment model to predict the risk of blood clots could facilitate selection of patients for prophylaxis and optimise the balance of benefits, risks and costs. We aimed to identify validated risk assessment models and estimate their prognostic accuracy, evaluate the cost-effectiveness of different strategies for selecting hospitalised patients for prophylaxis, assess the feasibility of using efficient research methods and estimate key parameters for future research. We undertook a systematic review, decision-analytic modelling and observational cohort study conducted in accordance with Enhancing the QUAlity and Transparency Of health Research (EQUATOR) guidelines. NHS hospitals, with primary data collection at four sites. Medical and surgical hospital inpatients, excluding paediatric, critical care and pregnancy-related admissions. Prophylaxis for all patients, none and according to selected risk assessment models. Model accuracy for predicting blood clots, lifetime costs and quality-adjusted life-years associated with alternative strategies, accuracy of efficient methods for identifying key outcomes and proportion of inpatients recommended prophylaxis using different models. We identified 24 validated risk assessment models, but low-quality heterogeneous data suggested weak accuracy for prediction of blood clots and generally high risk of bias in all studies. Decision-analytic modelling showed that pharmacological prophylaxis for all eligible is generally more cost-effective than model-based strategies for both medical and surgical inpatients, when valuing a quality-adjusted life-year at £20,000. The findings were more sensitive to uncertainties in the surgical population; strategies using risk assessment models were more cost-effective if the model was assumed to have a very high sensitivity, or the long-term risks of post-thrombotic complications were lower. Efficient methods using routine data did not accurately identify blood clots or bleeding events and several pre-specified feasibility criteria were not met. Theoretical prophylaxis rates across an inpatient cohort based on existing risk assessment models ranged from 13% to 91%. Existing studies may underestimate the accuracy of risk assessment models, leading to underestimation of their cost-effectiveness. The cost-effectiveness findings do not apply to patients with an increased risk of bleeding. Mechanical thromboprophylaxis options were excluded from the modelling. Primary data collection was predominately retrospective, risking case ascertainment bias. Thromboprophylaxis for all patients appears to be generally more cost-effective than using a risk assessment model, in hospitalised patients at low risk of bleeding. To be cost-effective, any risk assessment model would need to be highly sensitive. Current evidence on risk assessment models is at high risk of bias and our findings should be interpreted in this context. We were unable to demonstrate the feasibility of using efficient methods to accurately detect relevant outcomes for future research. Further research should evaluate routine prophylaxis strategies for all eligible hospitalised patients. Models that could accurately identify individuals at very low risk of blood clots (who could discontinue prophylaxis) warrant further evaluation.

Small bites versus large bites during fascial closure of midline laparotomies: a systematic review and meta-analysis.

Incisional ventral hernias (IVH) are common after laparotomies, with up to 20% incidence in 12months, increasing up to 60% at 3-5years. Although Small Bites (SB) is the standard technique for fascial closure in laparotomies, its adoption in the United States is limited, and Large Bites (LB) is still commonly performed. We aim to assess the effectiveness of SB regarding IVH. We searched for RCTs and observational studies on Cochrane, EMBASE, and PubMed from inception to May 2023. We selected patients ≥ 18years old, undergoing midline laparotomies, comparing SB and LB for IVH, surgical site infections (SSI), fascial dehiscence, hospital stay, and closure duration. We used RevMan 5.4. and RStudio for statistics. Heterogeneity was assessed with I2 statistics, and random effect was used if I2 > 25%. 1687 studies were screened, 45 reviewed, and 6 studies selected, including 3 RCTs and 3351 patients (49% received SB and 51% LB). SB showed fewer IVH (RR 0.54; 95% CI 0.39-0.74; P < 0.001) and SSI (RR 0.68; 95% CI 0.53-0.86; P = 0.002), shorter hospital stay (MD -1.36days; 95% CI -2.35, -0.38; P = 0.007), and longer closure duration (MD 4.78min; 95% CI 3.21-6.35; P < 0.001). No differences were seen regarding fascial dehiscence. SB technique has lower incidence of IVH at 1-year follow-up, less SSI, shorter hospital stay, and longer fascial closure duration when compared to the LB. SB should be the technique of choice during midline laparotomies.

Efficacy and Safety of Medical Thoracoscopic Bulla Volume Reduction in the Treatment of Chronic Obstructive Pulmonary Disease Combined With Giant Emphysematous Bullae

To explore the efficacy and safety of medical thoracoscopic bulla volume reduction for the treatment of chronic obstructive pulmonary disease (COPD) combined with giant emphysematous bullae (GEB). A total of 66 patients with COPD combined with GEB were enrolled in the study. All the subjects received treatment at Zhengzhou Central Hospital affiliated with Zhengzhou University between March 2021 and December 2022. The subjects were divided into two groups, a medical thoracoscope group consisting of 30 cases treated with medical thoracoscopic bulla volume reduction and a surgical thoracoscope group consisting of 36 cases treated by video-assisted thoracoscopic surgery. All patients were followed up before discharge and 3 months and 6 months after discharge. The preoperative and postoperative levels of the pulmonary function, 6-minute walk distance (6MWD), and St. George's Respiratory Questionnaire (SGRQ) scores and differences in postoperative complications were compared between the two groups. The operative duration, postoperative length-of-stay, and surgical costs and hospitalization bills, and the maximum visual analog scale (VAS) pain scores at 24 h after the procedure were assessed. The baseline data of the two groups were comparable, showing no statistically significant difference. The forced expiratory volume in 1 second (FEV1) 6 months after the procedures improved in both the medical thoracoscopy group ([0.78±0.29] L vs. [1.02±0.31] L, P<0.001) and the surgical thoracoscopy group ([0.80±0.21] L vs. [1.03±0.23] L, P<0.001) compared to that before the procedures. Improvements to a certain degree in 6MWT and SGRQ scores were also observed in the two groups at 3 months and 6 months after the procedures (P<0.05). In addition, no statistically significant difference in these indexes was observed during the follow-up period of the patients in the two groups. There was no significant difference in operating time between the two groups. The medical thoracoscopy group had shorter postoperative length-of-stay ([7.3±2.6] d) and 24-hour postoperative VAS pain scores (3.0 [2.0, 3.3]) than the surgical thoracoscopic group did ([10.4±4.3] d and 4.5 [3.0, 5.0], respectively), with the differences being statistically significant (P<0.05). Surgical cost and total hospitalization bills were lower in the medical thoracoscopy group than those in the surgical thoracoscopy group (P<0.05). The complication rate in the medical thoracoscopy group was lower than that in the surgical thoracoscopy group (46.7% vs. 52.8%), but the difference was not statistically significant. Medical thoracoscopic reduction of bulla volume can significantly improve the pulmonary function, quality of life, and exercise tolerance of patients with COPD combined with GEB, and it can reduce postoperative short-term pain and shorten postoperative length-of-stay. The procedure has the advantages of minimal invasiveness, quick recovery, and low costs. Hence extensive clinical application is warranted.

Discordance Therapeutic Protocol of Cystic Echinococcosis With WHO Guideline: A Descriptive Study Based on Liver Ultra-Sonographic Data in North Khorasan Province, Northeastern of Iran.

Cystic echinococcosis (CE), a helminth-associated zoonosis caused by Echinococcus granulosus, poses a significant public health problem, particularly in pastoral-rearing regions. The lack of uniform guidelines led to variations in CE management. Based on ultrasound data, the World Health Organization Informal Working Group on Echinococcosis (WHO-IWGE) classification system categorizes cysts into active, transitional, and inactive groups. This study assesses whether the therapeutic approach from liver human operation cases in North Khorasan province aligns with the WHO-IWGE reference based on ultrasound data. The research is based on ultrasound data from liver CE human operation cases collected between 2018 and 2022. This retrospective study investigates the therapeutic protocol for (CE) in North Khorasan Province, Iran, comparing it with the WHO-IWGE guidelines. We collect data from previously registered patients' medical information from our studied area's main CE surgical hospital. Moreover, as the first hospitalized survey in Iran, this study reveals insights into patient demographics, cyst stage prevalence, and treatment modalities. Notably, more than half of the patients were treated for CE1 stage cysts, and CE4 cases, which generally do not require surgery, underwent open surgery. The results suggest a need for adherence to the "watch-and-wait" approach in specific cases. All patients underwent successful surgeries, but we do not have access to follow-up data from patients after discharge. This descriptive study contributes to understanding the implementation of WHO guidelines in a regional context, shedding light on the challenges and variations in CE management. It seems, retraining courses for surgeons are required to update their knowledge of standard CE diagnostic and treatment methods.

Site of Service Disparities Exist for Total Joint Arthroplasty.

The rate of outpatient total joint arthroplasty procedures, including those performed at ambulatory surgical centers (ASCs) and hospital outpatient departments, is increasing. The purpose of this study was to analyze if type of insurance is associated with site of service (in-patient vs outpatient) for total joint arthroplasty and adverse outcomes. We identified patients undergoing unicompartmental knee arthroplasty (UKA), total knee arthroplasty (TKA), or total hip arthroplasty (THA) using Current Procedural Terminology codes in a national administrative claims database. Eligible patients were stratified by type of insurance (Medicaid, Medicare, private). The primary outcome was site of service. Secondary outcomes included general complications, procedural complications, and revision procedures. We evaluated the associations using adjusted multivariable logistic regression models. We identified 951,568 patients for analysis; 46,703 (4.9%) patients underwent UKA, 607,221 (63.8%) underwent TKA, and 297,644 (31.3%) underwent THA. Overall, 9.6% of procedures were outpatient. Patients with Medicaid were less likely than privately insured patients to receive outpatient UKA or THA (UKA: odds ratio [OR], 0.729 [95% CI, 0.640-0.829]; THA: OR, 0.625 [95% CI, 0.557-0.702]) but more likely than patients with Medicare to receive outpatient TKA or THA (TKA: OR, 1.391 [95% CI, 1.315-1.472]; THA: OR, 1.327 [95% CI, 1.166-1.506]). Patients with Medicaid were more likely to experience complications and revision procedures. Differences in site of service and complication rates following hip and knee arthroplasty exist based on type of insurance, suggesting a disparity in care. Further exploration of drivers of this disparity is warranted and can inform interventions (eg, progressive value-based payments) to support equity in orthopedic services.
