Clinical characteristics and literature review of chronic active Epstein–Barr virus‐associated enteritis

Key Clinical MessageChronic active Epstein‐Barr virus (EBV) infection‐associated enteritis (CAEAE) in nonimmunodeficient individuals is rare. To report a case of CAEAE, relevant articles were searched through databases. The clinical manifestations, endoscopic findings, strategies of treatment, prognoses, and follow‐up results of CAEAE patients were analyzed. Including this report, seven citations in the literature provide descriptions of 27 cases of CAEAE. There were 21 males and six females, with a mean age of 40 years. The main clinical manifestations were fever (25/27), abdominal pain (14/27), diarrhea (16/27), hematochezia or bloody stools (13/27), and decreased hemoglobin and red blood cell counts in routine blood tests (14/27). Elevations in inflammatory markers, white blood cell (WBC) counts, and C‐reactive protein (CRP) were common. Coagulation was often abnormal. Histopathology confirmed EBV‐encoded small nuclear RNA (EBER) in the affected tissue via in situ hybridization. The average serum EBV DNA load was 6.3 × 10^5 copies/mL. All patients had varying degrees of intestinal ulcers endoscopically, and the ulcers and pathology were uncharacterized and misdiagnosed mostly as inflammatory bowel disease (IBD). The course of the disease was progressive and later complicated by intestinal bleeding, intestinal perforation, septic shock, and a high rate of emergency surgery. However, the conditions of the patients often did not improve after surgery, and some patients soon died due to reperforation or massive hematochezia. Hormone and antiviral treatment had no obvious effect. There was a significant difference in surgical and nonsurgical survival (p < 0.05). The proportion of patients who died within 6 months was as high as 63.6% (7/11). CAEAE belongs to a group of rare, difficult conditions, has an insidious clinical course, has a high case fatality rate, and may later develop into EBV‐positive lymphoproliferative disorder (EBV‐LPD), which in turn leads to carcinogenesis. Clinicians should raise awareness that in patients with multiple ulcers in the intestine of unknown etiology, attention should be paid to EBV serology, and histology to make the diagnosis as early as possible.

Access to and quality of elective care: a prospective cohort study using hernia surgery as a tracer condition in 83 countries

Timely and safe elective health care facilitates return to normal activities for patients and prevents emergency admissions. Surgery is a cornerstone of elective care and relies on complex pathways. This study aimed to take a whole-system approach to evaluating access to and quality of elective health care globally, using inguinal hernia as a tracer condition. This was a prospective, international, cohort study conducted between Jan 30 and May 21, 2023, in which any hospital performing inguinal hernia repairs was eligible to take part. Consecutive patients of any age undergoing primary inguinal hernia repair were included. A measurement set mapped to the attributes of WHO's Health System Building Blocks was defined to evaluate access (emergency surgery rates, bowel resection rates, and waiting times) and quality (mesh use, day-case rates, and postoperative complications). These were compared across World Bank income groups (high-income, upper-middle-income, lower-middle-income, and low-income countries), adjusted for hospital and country. Factors associated with postoperative complications were explored with a three-level multilevel logistic regression model. 18 058 patients from 640 hospitals in 83 countries were included, of whom 1287 (7·1%) underwent emergency surgery. Emergency surgery rates increased from high-income to low-income countries (6·8%, 9·7%, 11·4%, 14·2%), accompanied by an increase in bowel resection rates (1·2%, 1·4%, 2·3%, 4·2%). Overall waiting times for elective surgery were similar around the world (median 8·0 months from symptoms to surgery), largely because of delays between symptom onset and diagnosis rather than waiting for treatment. In 14 768 elective operations in adults, mesh use decreased from high-income to low-income countries (97·6%, 94·3%, 80·6%, 61·0%). In patients eligible for day-case surgery (n=12 658), day-case rates were low and variable (50·0%, 38·0%, 42·1%, 44·5%). Complications occurred in 2415 (13·4%) of 18 018 patients and were more common after emergency surgery (adjusted odds ratio 2·06, 95% CI 1·72-2·46) and bowel resection (1·85, 1·31-2·63), and less common after day-case surgery (0·39, 0·34-0·44). This study demonstrates that elective health care is essential to preventing over-reliance on emergency systems. We identified actionable targets for system strengthening: clear referral pathways and increasing mesh repair in lower-income settings, and boosting day-case surgery in all income settings. These measures might strengthen non-surgical pathways too, reducing the burden on society and health services.

Higher Rates Of Emergency Surgery, Serious Complications, And Readmissions In Primary Care Shortage Areas, 2015-19.

Primary care physicians are often the first to screen and identify patients with access-sensitive surgical conditions that should be treated electively. These conditions require surgery that is preferably planned (elective), but, when access is limited, treatment may be delayed and worsening symptoms lead to emergency surgery (for example, colectomy for cancer, abdominal aortic aneurysm repair, and incisional hernia repair). We evaluated the rates of elective versus emergency surgery for patients with three access-sensitive surgical conditions living in primary care Health Professional Shortage Areas during 2015-19. Medicare beneficiaries in more severe primary care shortage areas had higher rates of emergency surgery compared with rates in the least severe shortage areas (37.8percent versus 29.9percent). They were also more likely to have serious complications (14.9percent versus 11.7percent) and readmissions (15.7percent versus 13.5percent). When we accounted for areas with a shortage of surgeons, the findings were similar. Taken together, these findings suggest that residents of areas with greater primary care workforce shortages may also face challenges in accessing elective surgical care. As policy makers consider investing in Health Professional Shortage Areas, our findings underscore the importance of primary care access to a broader range of services.

Treatment of patients with screen-detected colorectal cancer is less strenuous: a nationwide cohort study with long-term follow-up

ObjectiveDuring the last two decades, organised colorectal cancer (CRC) screening has been widely implemented. It remains to be established if screen-detected CRC (SD-CRC) is associated with reduced long-term requirements for treatment as compared with patients with non-screen-detected CRC (NSD-CRC). Study design and methodsThis nationwide cohort study evaluated differences in treatment and healthcare contacts from the date of diagnosis to two years after comparing patients with SD-CRC and NSD-CRC. Data were collected from national healthcare registers, including patients aged 50–75 years and diagnosed with CRC between January 1st 2014 and March 31st 2018. Analyses were stratified into UICC stages and adjusted for sex, 5-year age groups, type of cancer (colonic/rectal), and Charlson comorbidity index score to address healthy user bias. ResultsIn total, 12,040 patients were included, 4708 with SD-CRC and 7332 with NSD-CRC. In patients with SD-CRC, the duration of hospitalisation and rate of emergency surgery were reduced by 38 % (relative risk [RR] = 0.62) and 66 % (RR = 0.34), respectively. Moreover, this group was characterised by a 75 % reduction in oncological outpatient visits (RR = 0.35) and a reduced number of treatments with chemotherapy (RR = 0.57) and radiotherapy (RR = 0.50). There were no significant differences between the two populations in the rates of metastasectomy and the number of contacts with primary healthcare providers. ConclusionCompared to patients with NSD-CRC, patients with SD-CRC experience less hospitalisation and treatment within the first two years after diagnosis.

Umblikal Hernili Hastaların Değerlendirilmesi: 6 Yıllık Deneyim

Objective: Umbilical hernia is a common anterior abdominal wall defect in childhood. Although the defect is present at birth, unlike other hernias of childhood, it may close spontaneously over time without the need for surgery. However, when these hernias do not close spontaneously, complications can develop that require emergency surgery. The aim of this study was to determine the incidence of spontaneous closure in patients diagnosed with umbilical hernia and the factors that influence this incidence, the complications that may develop during follow-up, the indications for surgery and the issues to consider when planning the follow-up of patients. Material and Methods: Between January 2006 and December 2011, 1928 patients diagnosed with umbilical hernia and followed up and treated in our clinic were included in the study. In this retrospective cohort study the current size of umbilical hernia, comorbidities and demographic characteristics of the patients were analysed. Operative data, complications and postoperative follow-up of the operated patients were evaluated. Results: The spontaneous closure rate of umbilical hernia was found to be 60%. The rate of spontaneous closure of umbilical hernia was higher in boys and the rate of operation was higher in girls. The risk of incarceration was higher in girls than in boys. The rate of spontaneous closure decreased with increasing defect size. It was found that comorbidities did not affect spontaneous closure of umbilical hernias. The rate of emergency surgery for incarceration was low (2%). Strangulation was noted in 1% of patients. All patients with incarceration were in Lassaletta group 2 (defect diameter 0.5-1.5 cm). Conclusion: Conservative management is still the most accepted and safest method in the treatment of umbilical hernia. Incarceration and strangulation are very rare in umbilical hernias. Even if the umbilical hernia is complicated, surgical treatment is possible and peri- and post-operative complication rates are very low. Long-term morbidity and mortality due to incarceration have not been reported in the literature.

Impact of early diagnosis on surgical outcomes in patients with Loeys-Dietz syndrome.

This study aimed to investigate the influence of early diagnosis (ED) on surgical outcomes in patients definitively diagnosed with Loeys-Dietz syndrome (LDS). A retrospective review was conducted on 38 patients with LDS who underwent aortic surgery at our institution between January 1995 and June 2022. The primary endpoint was freedom from aortic reoperation. Among the patients, the median age at the initial surgery was 33 (range: 39-44) years, and 23 (60.5%) patients were male. Twenty-one (55.3%; aortic dissection or rupture (n = 2) and aneurysm (n = 19)) patients were diagnosed with LDS before the initial surgery (ED group). Meanwhile, the remaining 17 (44.7%; aortic dissection or rupture (n = 13) and aneurysm (n = 4)) patients were after surgery [delayed diagnosis (DD) group]. The ED group had significantly lower rates of emergency surgery and concomitant arch procedure (P < .001, respectively) but a higher rate of valve-sparing root surgery (P = .018) compared to the DD group. No in-hospital mortality was observed in either group. Nevertheless, the ED group had a shorter postoperative hospital stay (median difference: 3 days, P = .032) and a lower rate of aortic reoperation (P = .013). Early detection of LDS may help in preventing acute aortic syndrome, reducing the risk of aortic reoperation, and potentially shortening hospital stay. Careful medical management before surgery could contribute to better clinical outcomes and an improved quality of life for patients with LDS.

Greater need but reduced access: a population study of planned and elective surgery rates in adult mental health service users.

Timely access to surgery is an essential part of healthcare. People living with mental health (MH) conditions may have higher rates of chronic illness requiring surgical care but also face barriers to care. There is limited evidence about whether unequal surgical access contributes to health inequalities in this group. We examined 1.22 million surgical procedures in public and private hospitals in New South Wales (NSW), Australia, in 2019. In a cross-sectional study of 76,320 MH service users aged 18 and over, surgical procedure rates per 1,000 population were compared to rates for 6.23 million other NSW residents after direct standardisation for age, sex and socio-economic disadvantage. Rates were calculated for planned and emergency surgery, for major specialty groups, for the top 10 procedure blocks in each specialty group and for 13 access-sensitive procedures. Subgroup analyses were conducted for hospital and insurance type and for people with severe or persistent MH conditions. MH service users had higher rates of surgical procedures (adjusted incidence rate ratio [aIRR]: 1.53, 95% CI: 1.51-1.56), due to slightly higher planned procedure rates (aIRR: 1.22, 95% CI: 1.19-1.24) and substantially higher emergency procedure rates (aIRR: 3.60, 95% CI: 3.51-3.70). Emergency procedure rates were increased in all block groups with sufficient numbers for standardisation. MH service users had very high rates (aIRR > 4.5) of emergency cardiovascular, skin and plastics and respiratory procedures, higher rates of planned coronary artery bypass grafting, coronary angiography and cholecystectomy but lower rates of planned ophthalmic surgery, cataract repair, shoulder reconstruction, knee replacement and some plastic surgery procedures. Higher rates of surgery in MH service users may reflect a higher prevalence of conditions requiring surgical care, including cardiac, metabolic, alcohol-related or smoking-related conditions. The striking increase in emergency surgery rates suggests that this need may not be being met, particularly for chronic and disabling conditions which are often treated by planned surgery in private hospital settings in the Australian health system. A higher proportion of emergency surgery may have serious personal and health system consequences.

Surgical neonates: A retrospective review of procedures and postoperative outcomes at a quaternary children's hospital.

Neonates have a high incidence of respiratory and cardiac perioperative events. Disease severity and indications for surgical intervention often dovetail with an overall complex clinical course and predispose these infants to adverse long-term neurodevelopmental outcomes and increased length of stay. Our aims were to describe severe and nonsevere early postoperative complications to establish a baseline of care outcomes and to identify subgroups of surgical neonates and procedures for future prospective studies. Electronic health record data were examined retrospectively for a cohort of patients who had general anesthesia from January 26, 2015 to August 31, 2018. Inclusion criteria were full-term infants with postmenstrual age less than 44 weeks or premature infants less than 60 weeks postmenstrual age undergoing nonimaging, noncardiac surgery. Severe postoperative complications were defined as mortality, reintubation, positive blood culture, and surgical site infection. Nonsevere early postoperative outcomes were defined as hypoglycemia, hyperglycemia, hypothermia, hyperthermia, and readmission within 30 days. About 2569 procedures were performed in 1842 neonates of which 10.9% were emergency surgeries. There were 120 postoperative severe complications and 965 nonsevere postoperative outcomes. Overall, 30-day mortality was 1.8% for the first procedure performed, with higher mortality seen on subgroup analysis for patients who underwent exploratory laparotomy (10.3%) and congenital lung lesion resection (4.9%). Postoperative areas for improvement included hyperglycemia (13.9%) and hypothermia (7.9%). The mortality rate in our study was comparable to other studies of neonatal surgery despite a high rate of emergency surgery and a high prevalence of prematurity in our cohort. The early outcomes data identified areas for improvement, including prevention of postoperative glucose and temperature derangements. Neonates in this cohort were at risk for severe and nonsevere adverse postoperative outcomes. Future studies are suggested to improve mortality and adverse event rates.

Paradigm shift towards emergency cholecystectomy: one site experience of the Chole-QuiC process.

Substantial evidence exists for the superiority of emergency over delayed cholecystectomy for gallstone disease during primary admission. Despite this, emergency surgery rates in the UK remain low compared with other developed countries, with great variation in care across the nation. We aimed to describe the local paradigm shift towards emergency surgery and investigate outcomes. This is a prospective observational study examining patients enrolled onto an emergency cholecystectomy pathway, following the hospital's subscription to the Royal College of Surgeons of England's Cholecystectomy Quality Improvement Collaborative (Chole-QuIC), between 1 December 2021 and 31 January 2023. Multivariate logistical regression models were used to identify patient and hospital factors associated with postoperative outcomes. Of the 307 suitable acute admissions, 261 (85%) had an emergency cholecystectomy, compared with 5% preceding the Chole-QuIC interventions. Waiting time dropped from 67 to 5 days. A total of 208 (79.7%) patients were primary presentations, 92 (35.2%) were classed Tokyo grade 2 and 142 (54.4%) were obese. A total of 23 (8.8%) patients underwent preoperative endoscopic retrograde cholangiopancreatography, and 26 (10%) patients had a subtotal cholecystectomy. Favourable outcomes (Clavien Dindo ≥3) were observed in first presentations (odds ratio (OR) 0.35; p=0.042) and for operation times within 7 days (OR 0.32; p=0.037), with worse outcomes in BMI ≥35 (OR 3.32; p=0.005) and operation time >7 days (OR 3.11; p=0.037). A paradigm shift towards emergency cholecystectomy benefits both the patient and the service. Positive outcomes are apparent for early operation in patients presenting for the first time and recurrent attendees, with early operation (<7 days) providing the most favourable outcome in a select patient group.

Risk factors for incisional hernia after gastrointestinal surgeries in non-tumor patients.

Incisional hernia (IH) is a common secondary ventral hernia after abdominal incisions and there is still little reliable evidence to predict and prevent IH. This study aimed to estimate risk factors of its incidence, especially concentrating on blood results. 96 patients received midline laparotomy for gastrointestinal benign diseases and suffered from IH were enrolled in the IH group. A control group of 192 patients were randomly selected from patients underwent midline laparotomy for gastrointestinal benign diseases without IH. Patients in the IH group exhibited higher age (P < 0.001), BMI (P < 0.001), hernia history (P = 0.001) and laparotomy history (P < 0.001). Rate of coronary heart disease (P = 0.046), hypertension (P < 0.001), diabetes (P = 0.008), incisional infection (P = 0.004) and emergency surgery (P = 0.041) were also higher in the IH group. Patients with IH had lower levels of Hb (P = 0.002), TP (P = 0.013), ALB (P < 0.001), A/G (P = 0.019), PA (P < 0.001), HDL-C (P = 0.008) and ApoA1 (P = 0.005). Meanwhile, patients in the control group bore lower levels of LDH (P = 0.008), GLU (P = 0.007), BUN (P = 0.048), UA (P = 0.021), TG (P = 0.011), TG/HDL-C (P = 0.002), TC/HDL-C (P = 0.013), ApoB/ApoA1 (P = 0.001) and Lp(a) (P = 0.001). A multivariate logistic regression revealed that high BMI, laparotomy history, incisional infection, decreased PA, elevated levels of UA, Lp(a) and ApoB/ApoA1 were independent risk factors of IH. This is the first study to reveal the relationship between IH and serum biochemical levels, and give a prediction through the nomograph model. These results will help surgeons identify high-risk patients, and take measures to prevent IH during the perioperative period.

Outcomes of initially nonoperative management of diverticulitis with abscess formation in immunosuppressed patients. DIPLICAB study COLLABORATIVE group.

Management of diverticulitis with abscess formation in immunosuppressed patients (IMS) remains unclear. The main objective of the study was to assess short- and long-term outcomes between IMS and immunocompetent patients (IC). The secondary aim was to identify risk factors for emergency surgery. A nationwide retrospective cohort study was performed at 29 Spanish referral centres between 2015-2019 including consecutive patients with first episode of diverticulitis classified as modified Hinchey Ib or II. IMS included immunosuppressive therapy, biologic therapy, malignant neoplasm with active chemotherapy and chronic steroid therapy. A multivariate analysis was performed to identify independent risk factors to emergency surgery in IMS. A total of 1395 patients were included; 118 IMS and 1277 IC. There were no significant differences in emergency surgery between IMS and IC (19.5% and 13.5%, p = 0.075) but IMS was associated with higher mortality (15.1% vs. 0.6%, p < 0.001). Similar recurrent episodes were found between IMS and IC (28% vs. 28.2%, p = 0.963). Following multivariate analysis, immunosuppressive treatment, p = 0.002; OR: 3.35 (1.57-7.15), free gas bubbles, p < 0.001; OR: 2.91 (2.01-4.21), Hinchey II, p = 0.002; OR: 1.88 (1.26-2.83), use of morphine, p < 0.001; OR: 3.08 (1.98-4.80), abscess size ≥5 cm, p = 0.001; OR: 1.97 (1.33-2.93) and leucocytosis at third day, p < 0.001; OR: 1.001 (1.001-1.002) were independently associated with emergency surgery in IMS. Nonoperative management in IMS has been shown to be safe with similar treatment failure than IC. IMS presented higher mortality in emergency surgery and similar rate of recurrent diverticulitis than IC. Identifying risk factors to emergency surgery may anticipate emergency surgery.

EGS P01 Embracing a Paradigm Shift: A Single-Centre Experience with the Chole-QuiC Process

Abstract Background Substantial evidence exists for the superiority ofemergency over delayed cholecystectomy for gallstone disease during primary admission. Despite this, emergency surgery rates in the United Kingdom remain low compared to other developed countries; with great variation in care across the nation. We aimed to describe the local paradigm shift towards emergency surgery and investigate outcomes. Methods A prospective observational study examining patients enrolled onto an emergency cholecystectomy pathway, following the hospital’s subscription to the Royal College of Surgeons of England’s Cholecystectomy Quality Improvement Collaborative (Chole-QuIC), between December 2021 and January 2023. Multivariate logistical regression models were used to identify patient and hospital factors associated with post-operative outcomes. Results 261/307 (85%) of all suitable acute admissions had an emergency cholecystectomy, compared to 5% the preceding four years. Waiting time dropped from 67 to 5 days. 208 (79.7%) patients were primary presentations. 92 (35.2%) were classed Tokyo grade 2 and 142 (54.4%) were obese. 23 (8.8%) patients underwent a preoperative ERCP and 26 (10%) of patients had a subtotal cholecystectomy. Favourable outcomes (Clavien Dindo ≥3) were observed in first presentations (OR 0.35p=0.042) and operation times within 7 days (OR 0.32 p=0.037); with worse outcomes in BMI ≥35 (OR 3.32 p=0.005) and operation time &amp;gt;7 days (OR 3.11 p=0.037). Conclusions A paradigm shift towards emergency cholecystectomy benefits both the patient and the service. Positive outcomes are apparent for early operation in patients presenting for the first time and recurrent attendees, with early operation (&amp;lt;7 days) providing the most favourable outcome in a select patient group.

Differences in Management and Outcomes of Older and Younger Adults with Acute Severe Ulcerative Colitis.

Older adults with ulcerative colitis [UC] have greater morbidity than younger adults. The goal of this study was to investigate differences in the management and outcomes of older and younger patients hospitalised with severe UC. We conducted a retrospective cohort study of patients hospitalised for acute severe ulcerative colitis requiring intravenous steroids. We compared outcomes of adults aged ≥65 years with outcomes of younger patients. Primary study outcomes included frequency and timing of medical and surgical rescue therapy during the hospitalisation, postoperative complications, frailty, and mortality outcomes up to 1 year following the hospitalisation. Our cohort included 63 older adults [≥65 years] and 137 younger adults [14-64 years]. Despite similar disease severity at hospitalisation, older adults were half as likely to receive medical rescue therapy (odds ratio 0.45, 95% confidence interval [CI] 0.22-0.91). This difference was more striking among the frailest older adults. Older patients were similarly likely to undergo surgery but were more likely to undergo urgent or emergent procedures [50%] compared with younger patients [13%] [p <0.004]. The fraction of older adults at high risk for frailty increased from 33% pre-hospitalisation to 42% post-hospitalisation. Nearly one-third [27.8%] of older adults died within 1 year of hospitalisation, with half the deaths among older adults being attributable to UC or complications of UC. In comparison with younger patients, older adults had lower frequency use of medical rescue therapy, higher rates of emergency surgery, and increased mortality within 1 year. Further research is needed to optimise care pathways in this population.

The Outcome Of Sigmoid Volvulus Cases: A Single Centre Experiences Over 8 Years

Introduction&#x0D; Sigmoid volvulus is one of the causes of large bowel obstruction. Its management can be challenging because of its prevalence in high-risk individuals. This study was designed to review the management and outcome of all patients admitted with sigmoid volvulus.&#x0D; Methods&#x0D; A retrospective review of all patients admitted at Hospital Sultanah Nur Zahirah, Terengganu, for Sigmoid Volvulus from January 2015 to December 2022 was performed. The data was extracted from Hospital Information System (HIS) and analysed using SPSS 27.&#x0D; Results&#x0D; Twenty-four patients were admitted, a total of 41 admissions for sigmoid volvulus during the study periods. The majority of the patients (n=16, 66.7%) were male and (n=8,33.3%) were female. Seven (29.2%) patients underwent emergency surgery on the presentation, and three (12.5%) patients died on admission due to septic shock. The remaining 14 (58.3%) were managed by endoscopic decompression. 13 (92.9%) patients had successful decompression procedures, and one patient (7.1%) failed, which required emergency surgery. About seven patients (53.8%) were readmitted for recurrence of sigmoid volvulus after successful decompression on initial admission, in which subsequently all of them required emergency surgery. The remaining six (46.2%) did not experience any recurrence episodes, and three (50%) of them underwent subsequent elective surgery. In our series, three patients died on initial presentation due to perforation and septic shock without any intervention, two patients died after emergency surgery due to septic shock and multi-organ failure, and one patient died due to covid 19 pneumonia. There was no mortality after elective surgery.&#x0D; Conclusion&#x0D; Sigmoid volvulus is a surgical emergency in which the majority (58.3%) can be successfully decompressed non-operatively. Emergency surgery in these patients is associated with 13.3% mortality in our series. Elective definitive surgery is suggested in view of the high recurrence rate (&gt;50%) and considerable risk of emergency surgery.

Rate of Emergency Lower Extremity Amputations in the United States Among Medicare Beneficiaries.

To determine the rate of emergency versus elective lower extremity amputations in the United States. Lower extremity amputation is a common endpoint for patients with poorly controlled diabetes and multilevel peripheral vascular disease. Although the procedure is ideally performed electively, patients with limited access may present later and require an emergency operation. To what extent rates of emergency amputation for lower extremities vary across the United States is unknown. Evaluation of Medicare beneficiaries who underwent lower extremity amputation between 2015 and 2020. The rate was determined for each zip code and placed into rank order from lowest to highest rate. We merged each beneficiary's place of residence and location of care with the American Hospital Association Annual Survey using Google Maps Application Programming Interface to determine the travel distance for patients to undergo their procedure. Of 233,084 patients, 66.3% (154,597) were men, 69.8% (162,786) were White. The average age (SD) was 74 years (8). There was wide variation in rates of emergency lower extremity amputation. The lowest quintile of zip codes demonstrated an emergency amputation rate of 3.7%, whereas the highest quintile demonstrated 90%. The median travel distance in the lowest emergency surgery rate quintile was 34.6 miles compared with 10.5 miles in the highest quintile of emergency surgery ( P < 0.001). There is wide variation in the rate of emergency lower extremity amputations among Medicare beneficiaries, suggesting variable access to essential vascular care. Travel distance and rate of amputation have an inverse relationship, suggesting that barriers other than travel distance are playing a role.

FTP6.4 Management and Outcomes of Acute Diverticulitis in Immunosuppressed Patients

Abstract Aims Previous studies have suggested that immunosuppressed patients with acute diverticulitis are at high risk of failing conservative management and many will require urgent surgical intervention. Some series have shown mortality rates as high as 39% and 56% with medical and surgical management respectively. The aim of this study was to analyse the management and outcomes of immunosuppressed patients presenting with acute diverticulitis. Methods Data were collected on patients admitted as an emergency with acute diverticulitis over a 2-year period (1st January 2018 to 31st December 2019). Immunosuppressed patients were identified and divided into 5 groups according to the cause: group 1, chronic corticosteroid use; group 2, transplant patients; group 3, malignant neoplasm; group 4 chronic kidney disease; group 5, other immunosuppressant treatments. Outcomes were recorded. Results Sixty-one patients with immunosuppression were admitted with acute diverticulitis. The number of patients in groups 1-5 were 23, 2, 11, 16 and 9 respectively. Fifty-one patients (83.6%) had a CT during their admission and thirteen (21.3%) presented with complicated diverticulitis. Two patients (3.3%) underwent emergency surgery, both of whom were on chronic corticosteroid therapy and were alive at 1-year post-op. All fifty-nine patients (96.7%) managed conservatively survived admission. Conclusions This study has shown a lower rate of emergency surgery than previously observed and lower mortality with both medical and surgical management. Conservative management appears to be safe for the majority of immunosuppressed patients with acute diverticulitis.

The impact of primary tumor resection for asymptomatic colorectal cancer patients with unresectable metastases: a systematic review and meta-analysis.

Whether patients with asymptomatic primary tumors and unresectable metastases of colorectal cancer (CRC) should undergo primary tumor resection (PTR) remains controversial. This study aims to determine the appropriateness of PTR for these individuals by evaluating a number of outcome measures. A systematic literature search was performed. Outcome measures included overall survival, emergency surgery rates, incidence of postoperative complications, time to initiate chemotherapy, conversion rates, and chemotherapy-related toxicities. Patients who received PTR in addition to chemotherapy had a better overall survival rate than those who only received chemotherapy (HR = 0.62, 95%CI, 0.50-0.78, I2 = 84%, p < 0.00001). In the RCT subgroup, there were no significant differences with a HR of 0.72 (95%CI, 0.45-1.13, I2 = 17%, p = 0.15). More patients in the chemotherapy alone group could be converted to resectable status (OR = 0.47, 95%CI, 0.27-0.82, I2 = 0%, p = 0.008), but the incidence of emergency surgery was 23% (95%CI, 17-29%, I2 = 14%). The risk of chemotherapy-related toxicity was not significantly higher in the PTR group (OR = 1.5, 95%CI, 0.94-2.43, p = 0.09, I2 = 0%), with a 7% incidence of postoperative complications (95%CI, 0-14%, p = 0.05, I2 = 0%). The time to initiate chemotherapy after PTR was approximately 33.06days (95%CI, 25.55-40.58, I2 = 0%). PTR plus chemotherapy may be associated with improved survival in asymptomatic CRC patients with unresectable metastases. However, PTR did not provide a significant survival benefit in the subgroup of RCTs. Additionally, PTR did not result in a significantly increased risk of chemotherapy-related toxicity, with a postoperative complication rate of approximately 7%, and chemotherapy could be initiated at approximately 33.06days after PTR. Compared with the PTR plus chemotherapy, chemotherapy alone could result in a significantly higher conversion rate. However, about 23% of patients receiving chemotherapy alone required emergency surgery for primary tumor-related symptoms. The above results needed to be validated in future larger prospective randomized trials.

Impact of COVID-19 on the gastrointestinal surgical oncology patient population

BackgroundThe onset of the COVID-19 pandemic led to substantial alterations in healthcare delivery and access. In this study, we aimed to evaluate the impact of COVID-19 on the presentation and surgical care of patients with gastrointestinal (GI) cancers. MethodsAll patients who underwent GI cancer surgery at a large, tertiary referral center between March 15, 2019 and March 15, 2021 were included. March 15, 2020 was considered the start of the COVID-19 pandemic. Changes in patient, tumor, and treatment characteristics before the pandemic compared to during the pandemic were evaluated. ResultsOf 522 patients that met study criteria, 252 (48.3%) were treated before the COVID-19 pandemic. During the first COVID-19 wave, weekly volume of GI cancer cases was one-third lower than baseline (p = 0.041); during the second wave, case volume remained at baseline levels (p = 0.519). There were no demographic or tumor characteristic differences between patients receiving GI cancer surgery before versus during COVID-19 (p > 0.05 for all), and no difference in rate of emergency surgery (p > 0.9). Patients were more likely to receive preoperative chemotherapy during the first six months of the pandemic compared to the subsequent six months (35.6% vs. 15.5%, p < 0.001). Telemedicine was rapidly adopted at the start of the pandemic, rising from 0% to 47% of GI surgical oncology visits within two months. ConclusionsThe COVID-19 pandemic caused an initial disruption to the surgical care of GI cancers, but did not compromise stage at presentation. Preoperative chemotherapy and telemedicine were utilized to mitigate the impact of a high COVID-19 burden on cancer care.

Diverticulitis with abscess formation: Outcomes of non-operative management and nomogram for predicting emergency surgery: The Diplicab Study Collaborative Group

BackgroundTo assess short- and long-term outcomes from non-surgical management of diverticulitis with abscess formation and to develop a nomogram to predict emergency surgery. MethodsThis nationwide retrospective cohort study was performed in 29 Spanish referral centers, including patients with a first episode of a diverticular abscess (modified Hinchey Ib–II) from 2015 to 2019. Emergency surgery, complications, and recurrent episodes were analyzed. Regression analysis was used to assess risk factors, and a nomogram for emergency surgery was designed. ResultsOverall, 1,395 patients were included (1,078 Hinchey Ib and 317 Hinchey II). Most (1,184, 84.9%) patients were treated with antibiotics without percutaneous drainage, and 194 (13.90%) patients required emergency surgery during admission. Percutaneous drainage (208 patients) was associated with a lower risk of emergency surgery in patients with abscesses of ≥5 cm (19.9% vs 29.3%, P = .035; odds ratio 0.59 [0.37–0.96]). The multivariate analysis showed that immunosuppression treatment, C-reactive protein (odds ratio: 1.003; 1.001–1.005), free pneumoperitoneum (odds ratio: 3.01; 2.04–4.44), Hinchey II (odds ratio: 2.15; 1.42–3.26), abscess size 3 to 4.9 cm (odds ratio: 1.87; 1.06–3.29), abscess size ≥5 cm (odds ratio: 3.62; 2.08–6.32), and use of morphine (odds ratio: 3.68; 2.29–5.92) were associated with emergency surgery. A nomogram was developed with an area under the receiver operating characteristic curve of 0.81 (95% confidence interval: 0.77–0.85). ConclusionPercutaneous drainage must be considered in abscesses ≥5 cm to reduce emergency surgery rates; however, there are insufficient data to recommend it in smaller abscesses. The use of the nomogram could help the surgeon develop a targeted approach.

Features and outcomes of bailout repeat transcatheter aortic valve implantation (TAVI): the Bailout Acute TAVI-in-TAVI to Lessen Events (BATTLE) international registry

AimTranscatheter aortic valve implantation (TAVI) is a mainstay in the management of severe aortic stenosis in patients with intermediate to prohibitive surgical risk. When a single TAVI device fails and cannot be retrieved, TAVI-in-TAVI must be performed acutely, but outcomes of bailout TAVI-in-TAVI have been incompletely appraised. We aimed at analyzing patient, procedural and outcome features of patients undergoing bailout TAVI-in-TAVI in a multicenter registry.MethodsDetails of patients undergoing bailout TAVI-in-TAVI, performed acutely or within 24 h of index TAVI, in 6 international high-volume institutions, were collected. For every case provided, 2 same-week consecutive controls (prior TAVI, and subsequent TAVI) were provided. Outcomes of interest were procedural and long-term events, including death, myocardial infarction, stroke, access site complication, major bleeding, and reintervention, and their composite (i.e. major adverse events [MAE]).ResultsA total of 106 patients undergoing bailout TAVI-in-TAVI were included, as well as 212 controls, for a total of 318 individuals. Bailout TAVI-in-TAVI was less common in younger patients, those with higher body mass index, or treated with Portico/Navitor or Sapien devices (all p < 0.05). Bailout TAVI-in-TAVI was associated with higher in-hospital rates of death, emergency surgery, MAE, and permanent pacemaker implantation (all p < 0.05). Long-term follow-up showed that bailout TAVI-in-TAVI was associated with higher rates of death and MAE (both < 0.05). Similar findings were obtained at adjusted analyses (all p < 0.05). However, censoring early events, outlook was not significantly different when comparing the two groups (p = 0.897 for death, and p = 0.645 for MAE).ConclusionsBail-out TAVI-in-TAVI is associated with significant early and long-term mortality and morbidity. Thus, meticulous preprocedural planning and sophisticated intraprocedural techniques are of paramount importance to avoid these emergency procedures.
