Bariatric and general surgical procedures in obese patients with a history of venous thromboembolism and concurrent anticoagulation therapy.

OBJECTIVE: The objective of this study was to examine the use and outcomes of perioperative anticoagulation (AC) in obese patients with a known history of venous thromboembolism event (VTE). METHOD: A retrospective review of a prospective database for patients with a VTE history undergoing bariatric and general surgery at a single center (1/2008-12/2017) was performed. Factors assessed included demographics, surgical details, and outcomes. RESULTS: Sixty-five patients underwent 76 procedures: 46 females (71%); mean age 51 years (range 26-73), mean weight 284 pounds (range 110-558), mean body mass index 45 (range 19-87). Comorbidities include hypertension (60%), gastroesophageal reflux disease (54%), osteoarthritis (49%), obstructive sleep apnea (45%), and diabetes (37%). Operations: 22 general surgeries (29%), 20 sleeve gastrectomies (26%), 12 revisions/conversions (16%), 12 Roux-en-Y gastric bypasses (16%), and 10 gastric bands (13%). Modalities: 67% laparoscopic, 28% robotic, and 5% open. Twenty-two patients (34%) had a pre-operative inferior vena cava filter placed with no complications. The mean length of stay was 4.4 days (range 1-31). Complications: seven 30-day readmissions (9%), one 30-day reoperation (1%), and two 90-day VTEs (3%). Thirty-day readmissions: four for inability to tolerate PO, two for small bowel obstruction, and one for symptomatic anastomotic ulcer. CONCLUSIONS: In our patients, post-operative AC could be started without an increased risk of bleeding in patients with a history of VTE undergoing bariatric surgery.

CONCLUSIONES: En nuestros casos, la anticoagulación posoperatoria pudo iniciarse sin aumento del riesgo de sangrado en pacientes con antecedentes de TVE sometidos a cirugía bariátrica.

Morbidity and mortality of emergency surgery in octogenarian patient.

OBJECTIVE: To evaluate the health outcomes (postoperative morbidity and mortality) and the functional status at discharge of elderly patients older than 80 years who underwent emergency surgery. METHOD: Patients > 80 years of age who underwent emergency surgery during one year at the Marqués de Valdecilla University Hospital, Santander, Spain. Preoperative data (age, sex, type of surgery, comorbidity) and postoperative data (complications) were evaluated, as well as in-hospital mortality, at 30 days and 6 months after surgery. RESULTS: Five-hundred-sixty-eight patients underwent emergency surgery between 2018 and 2019. After the review, 407 patients were included in the study. Average age: 86.9 years. Women 61.7%. Mean hospital stay: 10.4 days. Traumatic interventions 41.3%, vascular surgery 19.7%, general-digestive surgery 25.3%. Medium ASA risk: 2.88. Functional status at discharge: 3.15. Postoperative complications: Clavien-Dindo I 40.8%, II 40.3%, IIIA 3.4%, IIIB 2.5%, IVA 3.9%, IVB 2.0% and V 7.1%. Hospital mortality 7.1%, 30-day mortality 10.3%, mortality at 6 months 24.6%. CONCLUSIONS: Patients > 80 years of age undergoing urgent surgery have high preoperative comorbidity, postoperative complications, and high mortality at 30 days and 6 months after surgery. This mortality is more significant in those ASA IV, nonagenarians and those undergoing high-risk surgery.

Abdominal hernias secondary to non-penetrating trauma. A systematic review.

Traumatic abdominal wall hernia (TAWH) is a protrusion of contents through a defect in the abdominal wall as a consequence of a blunt injury. The objective of this review was to describe demographic and clinical aspects of this rare pathology, identifying the optimal moment for surgical intervention, evaluating the need to use mesh, and analyzing the effectiveness of surgical treatment. Thus, a systematic review using PubMed, Embase, and Scopus databases was carried out between January 2004 and March 2024. Computed tomography is the gold-standard imaging test for diagnosis. Open surgery is generally the preferred approach, particularly in emergencies. Acute TAWH can be treated by primary suture or mesh repair, depending on local conditions, while late cases usually require mesh.

Scanning the aged to minimize missed injury: An EAST multicenter study.

BACKGROUND: Despite the high incidence of blunt trauma in older adults, there is a lack of evidence-based guidance for computed tomography (CT) imaging in this population. We aimed to identify an algorithm to guide use of a Pan-Scan (Head/C-spine/Torso) or a Selective Scan (Head/C-spine ± Torso). We hypothesized that a patient's initial history and exam could be used to guide imaging. METHODS: We prospectively studied blunt trauma patients aged 65+ at 18 Level I/II trauma centers. Patients presenting >24 h after injury or who died upon arrival were excluded. We collected history and physical elements and final injury diagnoses. Injury diagnoses were categorized into CT body regions of Head/C-spine or Torso (chest, abdomen/pelvis, and T/L spine). Using machine learning and regression modeling as well as a priori clinical algorithms based, we tested various decision rules against our dataset. Our priority was to identify a simple rule which could be applied at the bedside, maximizing sensitivity (Sens) and negative predictive value (NPV) to minimize missed injuries. RESULTS: We enrolled 5,498 patients with 3,082 injuries. Nearly half (47.1%, n = 2,587) had an injury within the defined CT body regions. No rule to guide a Pan-Scan could be identified with suitable Sens/NPV for clinical use. A clinical algorithm to identify patients for Pan-Scan, using a combination of physical exam findings and specific high-risk criteria, was identified and had a Sens of 0.94 and NPV of 0.86 This rule would have identified injuries in all but 90 patients (1.6%) and would theoretically spare 11.9% (655) of blunt trauma patients a torso CT. CONCLUSIONS: Our findings advocate for Head/Cspine CT in all geriatric patients with the addition of torso CT in the setting of positive clinical findings and high-risk criteria. Prospective validation of this rule could lead to streamlined diagnostic care of this growing trauma population. LEVEL OF EVIDENCE: Level 2, Diagnostic Tests or Criteria.

Predictors of Length of Hospital Stay After Reduction of Internal Hernia in Patients With a History of Roux-en-Y Gastric Bypass.

BACKGROUND: Postoperative internal hernias after Roux-en-Y gastric bypass (RYGB) have an incidence of 2%-9% and are a surgical emergency. Evidence on factors associated with length of stay (LOS) after emergent internal hernia reduction in RYGB patients is limited. METHODS: This is a retrospective review of patients who underwent internal hernia reduction after RYGB at our tertiary care center over a 5 year period from 2015 to 2020. Demographics, comorbidities, and intra- and postoperative hospital course were collected. Univariate and multivariate linear regressions were used to investigate factors associated with LOS. RESULTS: We identified 38 patients with internal hernia after RYGB. These patients with mean age 44.1 years were majority female (71.1%) and white race (60.5%). Of the 24 patients where the RYGB was done at our institution, the mean RYGB to IH interval was 43 months. Petersen's defect (57.8%) followed by jejuno-jejunal mesenteric defect (31.6%) were the most common locations for IH. Both Petersen's and jejuno-jejunal mesenteric hernias were found in 4 cases (10.5%). Revision of bypass and small bowel resection were required in 13.2% and 5.3% of cases, respectively. The median (interquartile range) length of stay (LOS) was 2 days. On the multivariate analysis, male sex (P = .019), conversion to exploratory laparotomy (P = .005), and resection of small bowel (P < .001) were independent risk factors for increased LOS. CONCLUSION: The most common location of IH after RYGB is Petersen's defect, followed by jejuno-jejunal mesenteric defect. LOS was significantly associated with male sex, exploratory laparotomy, and resection of small bowel.

Surgical Antibiotic Prophylaxis: A Proposal for a Global Evidence-Based Bundle.

In the multimodal strategy context, to implement healthcare-associated infection prevention, bundles are one of the most commonly used methods to adapt guidelines in the local context and transfer best practices into routine clinical care. One of the most important measures to prevent surgical site infections is surgical antibiotic prophylaxis (SAP). This narrative review aims to present a bundle for the correct SAP administration and evaluate the evidence supporting it. Surgical site infection (SSI) prevention guidelines published by the WHO, CDC, NICE, and SHEA/IDSA/APIC/AHA, and the clinical practice guidelines for SAP by ASHP/IDSA/SIS/SHEA, were reviewed. Subsequently, comprehensive searches were also conducted using the PubMed®/MEDLINE and Google Scholar databases, in order to identify further supporting evidence-based documentation. The bundle includes five different measures that may affect proper SAP administration. The measures included may be easily implemented in all hospitals worldwide and are based on minimal drug pharmacokinetics and pharmacodynamics knowledge, which all surgeons should know. Antibiotics for SAP should be prescribed for surgical procedures at high risk for SSIs, such as clean-contaminated and contaminated surgical procedures or for clean surgical procedures where SSIs, even if unlikely, may have devastating consequences, such as in procedures with prosthetic implants. SAP should generally be administered within 60 min before the surgical incision for most antibiotics (including cefazolin). SAP redosing is indicated for surgical procedures exceeding two antibiotic half-lives or for procedures significantly associated with blood loss. In principle, SAP should be discontinued after the surgical procedure. Hospital-based antimicrobial stewardship programmes can optimise the treatment of infections and reduce adverse events associated with antibiotics. In the context of a collaborative and interdisciplinary approach, it is essential to encourage an institutional safety culture in which surgeons are persuaded, rather than compelled, to respect antibiotic prescribing practices. In that context, the proposed bundle contains a set of evidence-based interventions for SAP administration. It is easy to apply, promotes collaboration, and includes measures that can be adequately followed and evaluated in all hospitals worldwide.

Impact of Enhanced Recovery After Surgery (ERAS) Combined with Bariatric Surgery Targeting Opioid Prescriptions (BSTOP) Protocol on Patient Outcomes, Length of Stay and Opioid Prescription After Bariatric Surgery.

BACKGROUND: Evidence shows that 14.2% of opioid-naive patients have long-term opioid dependence after bariatric surgery. Enhanced recovery after surgery (ERAS) protocols are widely used in bariatric surgery, while bariatric surgery targeting opioid prescriptions (BSTOP) protocols were recently introduced. We will investigate the combined impact of ERAS and BSTOP protocols after bariatric surgery. METHODS: We conducted a retrospective review for patients who underwent either a sleeve gastrectomy or Roux-en-Y gastric bypass at a tertiary care center. Pre-intervention and post-intervention data were compared. Primary outcomes were length of stay (LOS), 30-day readmission, 30-day complications, and discharge on opioids. Multivariate Poisson regression with robust standard error was used to analyze LOS. RESULTS: There was no significant difference in 30-day emergency room visits (3.3% vs. 4.0%; p value = 0.631), 30-day readmission (4.4% vs. 5.4%; p value = 0.577) or 30-day complication rate (4.2% vs. 6.4%; p value = 0.199). LOS was significantly lower in the post-intervention group; mean (interquartile range) 2 (1-2) days vs. 1 (1-2) day, p value < 0.001. On multivariate analysis, the post-intervention group had 0.74 (95% confidence interval 0.65-0.85; p value < 0.001) times lower LOS as compared to pre-intervention group. Patients with DM had a significantly longer LOS (relative risk: 1.22; p = 0.018). No other covariates were associated with LOS (p value < 0.05 for all). BSTOP analysis found a significant difference between the two groups. Discharge on opioids decreased from 40.6% pre-intervention to 7.1% post-intervention. CONCLUSION: ERAS and BSTOP protocols reduced length of stay and opioid need at discharge without an increase in complication or readmission rates.

Robotic-assisted completion cholecystectomy with repair of cholecystoduodenal fistula.

Post-cholecystectomy syndrome (PCS) is a well-documented complication of incomplete cholecystectomy. The etiology is often post-surgical chronic inflammation from unresolved cholelithiasis, which is secondary to anatomical abnormalities, including a retained gallbladder or a large cystic duct remnant (CDR). An exceedingly rare consequence is retained gallstone fistulization into the gastrointestinal tract. We present a case of a 70-year-old female with multiple comorbidities 4 years status-post incomplete cholecystectomy, who developed PCS with cholecystoduodenal fistula secondary to retained gallstone in the remnant gallbladder, with CDR involvement, treated via robotic-assisted surgery. Reoperation in PCS has been traditionally performed via laparoscopic approach with recent advances made in robotic-assisted surgery. However, we report the first documented case of PCS complicated by bilioenteric fistula repaired with robotic-assisted surgery. This highlights the value of robotic-assisted surgery in complicated cases, where one must contend with post-surgical anatomic abnormalities and visualization difficulties. Subsequent investigation is necessary to objectively quantify the safety and reproducibility of our approach.

Arcuate line hernia: a case report.

Arcuate line hernias are a rare type of hernia with limited publications regarding their successful repair. The arcuate line is the inferior limit of the posterior leaf of the rectus sheath. An arcuate line hernia is a type of intraparietal hernia, meaning it is not a truly complete fascial defect of the abdominal and, therefore, may present with atypical symptoms. Although published data on arcuate line hernia repairs are limited to a handful of case reports and one literature review, reports regarding robotic repair are exceptionally rare. This case report is the second documented robotic approach to arcuate line hernias known to these authors.

Kwashiorkor after gastric bypass.

Gastric bypass has grown in popularity in recent years due to its high efficacy in achieving long-term weight loss in patients with morbid obesity. Gastric bypass has been described to further exacerbate baseline nutritional deficiencies due to reduced gastric capacity and malabsorption. In rare cases, when protein deficiency is severe, Kwashiorkor disease may arise. The incidence of Kwashiorkor specifically following gastric bypass is rare, with an incidence of 4.7%. We report a case of a female patient who underwent a gastric bypass and subsequently developed Kwashiorkor. Physicians' suspicion of index for Kwashiorkor should be high for patients presenting with signs or symptoms of severe malnutrition following weight-loss procedures.

A prospective comparative study of the functional results associated with the use of Björk flap tracheostomy versus standard tracheostomy.

BACKGROUND: Placement of a tracheostomy for patients requiring prolonged mechanical ventilation (PMV) improves patients' comfort, decreases dead space ventilation, allows superior airway hygiene, and reduces the incidence of ventilator-associated pneumonia. Controversy still exists regarding the role of standard tracheostomy (ST) as opposed to the less frequently done Björk flap tracheostomy (BFT). This study compares the functional outcomes of these two techniques. STUDY DESIGN: Seventy-nine patients receiving tracheostomy in a 12-month period: 38 BFT vs. 41 ST. Data included demographics, indications for PMV, ventilator days before tracheostomy, time to and a number of patients who passed the fiberoptic endoscopic evaluation of swallowing (FEES), time to and a number of patients decannulated. RESULTS: Indications in both groups were PMV from trauma (18/38 vs 15/41), pneumonia (13/38 vs 13/41), and ARDS (7/38 vs 11/4), respectively (p > 0.05). Patients in both groups did not differ with regard to age, sex, GCS, duration of PMV before tracheostomy, the time to and a number of patients who passed the 1st FEES. However, the number of days and the number of FEES required before the next successful FEES in the 20 BFT and 21 ST patients who failed the 1st was 9 (4) vs. 16 (5), and 2 (1) vs. 4 (1), respectively (p < 0.05). Additionally, the number of intraoperative complications in aggregate were 0/38 in the BFT as opposed to 6/41 in the ST group (p < 0.05). CONCLUSION: We conclude that BFT may be associated with an overall shorter time to restoration of normal swallowing when compared to ST.

Crossing borders to change lives: Surgical mission amidst the COVID-19 pandemic.

INTRODUCTION: During the COVID pandemic, elective global surgical missions were temporarily halted for the safety of patients and travelling healthcare providers. We discuss our experience during our first surgical mission amidst the pandemic. We report a safe and successful treatment of the patients, detailing our precautionary steps and outcomes. METHODS: Retrospective manual chart review and data collection of patients' charts was conducted after IRB approval. We entail our experience and safety steps followed during screening, operating and postoperative care to minimize exposure and improve outcomes during a surgical mission in an outpatient setting during the pandemic. The surgical mission was from February 8 to February 12, 2022. RESULTS: A total of 60 patients who were screened. 33 patients underwent surgical intervention. One patient required postoperative hospitalization for a biliary duct leak. No patient or healthcare provider tested positive for COVID at the end of the mission. The average age of patients was 46.9 years. The average operative time was 116 min, and all patients had local nerve blocks. It included 45 health work providers. CONCLUSIONS: It is safe to perform outpatient international surgery during the pandemic while following pre-selected precautions.

Outcomes in Obese vs Non-Obese Injured Patients at a Level 1 Trauma Center and Bariatric Surgery Center of Excellence.

BACKGROUND: We hypothesized that the outcomes of trauma patients with a body mass index (BMI) equal to or greater than 30 compared to patients with BMI less than 30 would not differ at a level 1 trauma center that is also a Metabolic and Bariatric Surgery Center of Excellence in the Metabolic and Bariatric Surgery Accreditation Quality Improvement Program (MBSAQIP). STUDY DESIGN: Patients equal to and greater than 18 years old treated between 1/1/2018 and 12/31/2020 were included. Demographics, BMI, comorbidities, and outcomes (hospital-LOS, ICU-LOS, blood products used, and mortality) were compared between 2 groups: obese (BMI ≥30) vs non-obese (BMI <30). RESULTS: Of the 4192 patients identified, 3821 met the inclusion criteria; 3019 patients had a BMI <30, and 802 had a BMI ≥30. There was a statistically significant difference between the 2 groups with respect to gender (females: 57% vs 47%, P < .0001) and age (median: 80 [IQR: 63-88] vs 69 [IQR: 55-81], P < .0001). When adjusted for age, sex, DM, dementia, ISS, and ICU admission, there was no statistically significant difference in hospital-LOS (4.30 [95% CI: 4.10, 4.52] vs 4.48 [95% CI: 4.18, 4.79]) or mortality. No statistical differences were seen between the 2 groups in blood product use. CONCLUSIONS: Obesity did not correlate with poorer outcomes at an ACS-verified level 1 Trauma Center and Bariatric Surgery Center of Excellence. Further studies are needed to determine whether outcomes vary at hospitals without both designations.

Stop the Bleed: A Prospective Evaluation and Comparison of Tourniquet Application in Security Personnel Versus Civilian Population.

INTRODUCTION: Stop the Bleed (STB) is a national training program aiming to decrease the mortality associated with life-threatening bleeding due to injury. The purpose of this study was to evaluate the efficacy and confidence level of security personnel placing a tourniquet (TQ) compared to civilians. METHODS: Pre and post questionnaires were shared with security personnel (Group 1) and civilians (Group 2). Both groups were assessed to determine comfort level with TQ placement. Time and success rate for placement was recorded pre- and post-STB training. A generalized linear mixed model or generalized estimating equations was used to compare pre and post measurements. RESULTS: There were 234 subjects enrolled. There was a statistically significant improvement between the pre- and post-training responses in both groups with respect to comfort level in placing a TQ. Participants also demonstrated increased familiarity with the anatomy and bleeding control after STB training. A higher successful TQ placement was obtained in both groups after STB training (Pre-training: Group 1 [17.4%], Group 2 [12.8%]; Post-training: Group 1 [94.8%], Group 2 [92.3%]). Both groups demonstrated improved time to TA placement with a longer mean time improvement achieved in Group 1. Although the time to TQ placement pre-and post-training was statistically significant, we found that the post-training times between Groups 1 and 2 were similar (P = .983). CONCLUSIONS: Participants improved their confidence level with the use of hemorrhage control techniques and dramatically increased the rate and time to successful placement of a TQ. While civilians had the greatest increase in comfort level, the security personnel group saw the most significant reduction in the time to successful TQ placement. These findings highlight the critical role of STB in educating and empowering both civilians and security personnel in bleeding control techniques.

The First COVID-19 Pandemic Wave and the Effect on Health Care Trainees: A National Survey Study.

BACKGROUND: This study observes the trends and patterns among trainees during the coronavirus disease 2019 (COVID-19) pandemic and their response to resident education and hospital/program support. METHODS: An anonymous online 31-question survey was distributed to medical students and postgraduate year residents. Topics included were demographics, clinical responsibilities, educational/curricula changes, and trainee wellness. Descriptive analysis was performed for each set of demographic groupings as well as 2 and 3 group comparisons. RESULTS: Total 1051 surveys collected, 930 used for analysis: 373 (40.1%) male, 434 (46.6%) aged 30-34 years, 588 (63.2%) white, 417 (44.8%) married, 168 (18%) with children, and 323 (34.7%) from the Northeast region. The Northeast experienced difficulty sleeping, feelings of guilt, hopelessness, and changes in appetite (P = .0077). The pandemic interfered significantly with relationships and living situations (P < .0001). Trainees 18-34 years believed the pandemic affected residency training (P < .0001). Surgical residents were concerned about reaching numbers of operative procedures to graduate (P < .0001). Residency programs adhered to ACGME work restrictions (P < .0001). CONCLUSION: We aim to provide continued educational support for our trainees' clinical development and well-being during the COVID-19 pandemic.

Retrospective observational study correlating traumatic pelvic fractures and their associated injuries according to the Tile classification.

INTRODUCTION: Pelvic fractures due to high energy trauma present a high risk of associated injuries that compromise the functional and vital prognosis of the patients. The objective of this study was to analyze the relationship between traumatic pelvic fractures and their associated injuries according to the Tile classification. METHODS: Retrospective observational study of patients who suffered traumatic pelvic fractures (Type A, B or C of the Tile classification) with concomitant associated injuries, analyzing hemoglobin levels, between 6/2013 and 1/2016. RESULTS: A total of 42 patients were included; of those 69% (n = 29) were males, mean age was 48 years. 45% (n = 19) suffered traffic accidents and 26.2% (n = 11) falls. There was a different proportion in pelvic injuries: Tile A (n = 15, 35.7%), B (n = 20, 47.6%), and C (n = 7, 16.6%) of cases. 54.8% (n = 23) underwent surgery, 21.4% (n = 9) needed temporary or definitive external fixation. Significant differences were found between Tile A type and scapula fractures (P = .032), and Tile B with sacral fractures (P = .033) and visceral injuries (P = .049), while there is a tendency without a statistical significal between Tile C and costal fractures. 61.9% (n = 26) needed blood transfusion; 9.5% (n = 4) presented hypovolemic shock. CONCLUSIONS: Tile A pelvic fractures were associated with scapular fractures, and Tile B with transforaminal fractures of the sacrum and with visceral injuries (lungs, liver and genitourinary). The small number of Tile C prevent us to confirm an association with any pathology, although they are the ones which presnt more hemodynamically instability and thoracic injuries.
