Esophageal perforation: diagnostic work-up and clinical decision-making in the first 24 hours
Esophageal perforation is a rare and potentially life-threatening condition. Early clinical suspicion and imaging is important for case management to achieve a good outcome. However, recent studies continue to report high morbidity and mortality greater than 20% from esophageal perforation. At least half of the perforations are iatrogenic, mostly related to endoscopic instrumentation used in the upper gastrointestinal tract, while about a third are spontaneous perforations. Surgical treatment remains an important option for many patients, but a non-operative approach, with or without use of an endoscopic stent or placement of internal or external drains, should be considered when the clinical situation allows for a less invasive approach. The rarity of this emergency makes it difficult for a physician to obtain extensive individual clinical experience; it is also challenging to obtain firm scientific evidence that informs patient management and clinical decision-making. Improved attention to non-specific symptoms and signs and early diagnosis based on imaging may translate into better outcomes for this group of patients, many of whom are elderly with significant comorbidity
Post hepatectomy liver failure (PHLF) â Recent advances in prevention and clinical management
Under embargo until: 2021-09-10Background
Posthepatectomy liver failure (PHLF) is a relatively rare but feared complication following liver surgery, and associated with high morbidity, mortality and cost implications. Significant advances have been made in detailed preoperative assessment, particularly of the liver function in an attempt to predict and mitigate this complication.
Methods
A detailed search of PubMed and Medline was performed using keywords âliver failureâ, âliver insufficiencyâ, âliver resectionâ, âpostoperativeâ, and âpost-hepatectomyâ. Only full texts published in English were considered. Particular emphasis was placed on literature published after 2015. A formal systematic review was not found feasible hence a pragmatic review was performed.
Results
The reported incidence of PHLF varies widely in reported literature due to a historical absence of a universal definition. Incorporation of the now accepted definition and grading of PHLF would suggest the incidence to be between 8 and 12%. Major risk factors include background liver disease, extent of resection and intraoperative course. The vast majority of mortality associated with PHLF is related to sepsis, organ failure and cerebral events. Despite multiple attempts, there has been little progress in the definitive and specific management of liver failure. This review article discusses recent advances made in detailed preoperative evaluation of liver function and evidence-based targeted approach to managing PHLF.
Conclusion
PHLF remains a major cause of mortality following liver resection. In absence of a specific remedy, the best approach is mitigating the risk of it happening by detailed assessment of liver function, patient selection and general care of a critically ill patient.acceptedVersio
Intramural gastric pseudocyst: A case report and a comprehensive literature review
Rationale: Intramural pseudocyst, although first reported several decades ago, is a rare entity. Scientific knowledge regarding its clinical management is sparse. Patient concerns: We present three cases to show the diverse clinical patterns of patients diagnosed with an intramural gastric pseudocyst. Diagnosis: A final diagnosis should rest on proper evaluation by cross sectional imaging, including computer tomography and magnetic resonance imaging. Endoscopic ultrasound adds to the work-up. Interventions: Previously, identified âlesions of the gastric wallâ were not well recognized as an intramural pseudocyst, and treatments including resectional surgery were employed. Contemporary proper diagnostics should provide support to a less aggressive treatment approach. Outcomes: While an indolent natural history without any clinical symptoms or discomfort could be expected in most cases, individual clinical evaluation should be applied. Lessons: A heterogeneous information pattern from the limited number of cases in the literature makes it difficult to draw any firm conclusions. Attention to this rare condition should be increased to help clinicians arrive at a correct diagnosis and possibly prevent some patients from being over treated or from the use of unnecessary surgery.publishedVersio
A methodological framework for capturing relative eyetracking coordinate data to determine gaze patterns and fixations from two or more observers
While physical activity during cancer treatment is found beneficial for breast cancer patients, evidence indicates ambiguous findings concerning effects of scheduled exercise programs on treatment-related symptoms. This study investigated effects of a scheduled home-based exercise intervention in breast cancer patients during adjuvant chemotherapy, on cancer-related fatigue, physical fitness, and activity level. Sixty-seven women were randomized to an exercise intervention group (n=33, performed strength training 3x/week and 30 minutes brisk walking/day) and a control group (n=34, performed their regular physical activity level). Data collection was performed at baseline, at completion of chemotherapy (Post1), and 6-month postchemotherapy (Post2). Exercise levels were slightly higher in the scheduled exercise group than in the control group. In both groups, cancer-related fatigue increased at Post1 but returned to baseline at Post2. Physical fitness and activity levels decreased at Post1 but were significantly improved at Post2. Significant differences between intervention and control groups were not found. The findings suggest that generally recommended physical activity levels are enough to relief cancer-related fatigue and restore physical capacity in breast cancer patients during adjuvant chemotherapy, although one cannot rule out that results reflect diminishing treatment side effects over time
Epidemiology of abdominal trauma: An age- and sex-adjusted incidence analysis with mortality patterns
Purpose
Abdominal injuries may occur in up to one-third of all patients who suffer severe trauma, but little is known about epidemiological trends and characteristics in a Northern European setting. This study investigated injury demographics, and epidemiological trends in trauma patients admitted with abdominal injuries.
Methods
This was an observational cohort study of all consecutive patients admitted to Stavanger University Hospital (SUH) with a documented abdominal injury between January 2004 and December 2018. Injury demographics, age- and sex-adjusted incidence, and mortality patterns are analyzed across three time periods.
Results
Among 7202 admitted trauma patients, 449 (6.2%) suffered abdominal injuries. The median age was 31 years, and the age increased significantly over time (from a median of 25 years to a median of 38.5 years; p = 0.020). Patients with ASA 2 and 3 increased significantly over time. Men accounted for 70% (316/449). The injury mechanism was blunt in 91% (409/449). Transport-related accidents were the most frequent cause of injury in 57% (257/449). The median Injury Severity Score (ISS) was 21, and the median New Injury Severity Score (NISS) was 25. The annual adjusted incidence of all abdominal injuries was 7.2 per 100,000. Solid-organ injuries showed an annual adjusted incidence of 5.7 per 100,000. The most frequent organ injury was liver injury, found in 38% (169/449). Multiple abdominal injuries were recorded in 44% (197/449) and polytrauma in 51% (231/449) of the patients. Overall 30-day mortality was 12.5% (56/449) and 90-day mortality 13.6% (61/449).
Conclusion
The overall adjusted incidence rate of abdominal injuries remained stable. Age at presentation increased by over a decade, more often presenting with pre-existing comorbidities (ASA 2 and 3). The proportion of polytrauma patients was significantly reduced over time. Mortality rates were declining, although not statistically significant.publishedVersio
Characteristics and fate of patients with rectal cancer not entering a curative-intent treatment pathway: A complete nationwide registry cohort of 3,304 patients
Background: Treatment options for advanced and metastatic rectal cancer have increased during the past decades. However, a considerable proportion of the patients are not eligible for curative treatment, and data on this subset are scarce from a population-based perspective. This study aimed to describe treatment pathways and survival in a national cohort of patients with primary stage IV rectal cancer or stage I-III rectal cancer not eligible for curative treatment.
Methods: A national cohort of all patients reported 2008â2015 to the Norwegian Colorectal Cancer Registry with primary metastatic rectal cancer or who did not undergo curative resections for stage I-III rectal cancer was studied with regard to patient characteristics, treatments, and survival.
Results: Of 8291 patients diagnosed with rectal cancer, 3304 (39.9%) were eligible for analysis. The majority (76.8%) had metastatic disease, and 23.2% did not undergo curative resections for other reasons. We identified four main treatment journeys: no tumour-directed treatment, 25.1%; resection of the primary tumour, 44.6%; oncological treatment, 28.4%; and R0 resection of the primary tumour and metastases, 1.9%; these translated into ten different treatment pathways. Survival differed considerably between a median of 5.3 months for M1 disease with non-tumour-directed treatment to a five-year survival of 67% for M1 with R0 resection.
Conclusion: Almost 40% of all patients with rectal cancer did not enter a curative-intent treatment pathway. The patient journeys and outcomes varied greatly. This large but understudied population warrants further in-depth analyses of treatment efficacy and effects on quality of life.publishedVersio
Factors influencing treatment burden in colorectal cancer patients undergoing curative surgery: A cross-sectional study
Objective
To describe the severity of treatment burden in surgically treated colorectal cancer (CRC) patients and examine associations between treatment burden and demographic and clinical variables.
Methods
This cross-sectional study recruited 134 patients diagnosed with Dukesâ stage A-C CRC between 2016 and 2018 who underwent curative surgery. The Patient Experience with Treatment and Self-management (PETS) questionnaire assessed treatment burden domains of âworkloadâ, âstressorsâ and âimpactâ between 6 weeks and 18 months after primary surgery.
Results
Highest scores were observed for difficulty with healthcare services (median score 33.3), physical and mental fatigue (median score 30.0) and medical information (median score 26.8). Younger age, low education level or no cohabitants were significantly associated with higher workload PETS scores (p < 0.05, 0.013, p = 0.047, respectively). Higher PETS stressors scores were significantly associated with younger age (p = 0.006), lower education level (p = 0.016), and high comorbidity (p = 0.013). Higher PETS impact scores were significantly associated with the female sex (p = 0.050), younger age (p = <0.001â0.003), lower education (p = 0.003), no cohabitants (p = 0.003), high comorbidity (p = 0.003) and cancer stage Dukes A (p = 0.004).
Conclusions
A seamless and supportive healthcare system beyond hospitalisation targeting CRC subpopulations in danger of high treatment burden may improve patientsâ self-management experience.publishedVersio
Centralizing a national pancreatoduodenectomy service: striking the right balance
Background - Centralization of pancreatic surgery is currently called for owing to superior outcomes in higherâvolume centres. Conversely, organizational and patient concerns speak for a moderation in centralization. Consensus on the optimal balance has not yet been reached. This observational study presents a volumeâoutcome analysis of a complete national cohort in a health system with longâstanding centralization.
Methods - Data for all pancreatoduodenectomies in Norway in 2015 and 2016 were identified through a national quality registry and completed through electronic patient journals. Hospitals were dichotomized (highâvolume (40 or more procedures/year) or mediumâlowâvolume).
Results - Some 394 procedures were performed (201 in highâvolume and 193 in mediumâlowâvolume units). Major postoperative complications occurred in 125 patients (31¡7 per cent). A clinically relevant postoperative pancreatic fistula occurred in 66 patients (16¡8 per cent). Some 17 patients (4¡3 per cent) died within 90âdays, and the failureâtoârescue rate was 13¡6 per cent (17 of 125 patients). In multivariable comparison with the highâvolume centre, mediumâlowâvolume units had similar overall complication rates, lower 90âday mortality (odds ratio 0¡24, 95 per cent c.i. 0¡07 to 0¡82) and no tendency for a higher failureâtoârescue rate.
Conclusion - Centralization beyond medium volume will probably not improve on 90âday mortality or failureâtoârescue rates after pancreatoduodenectomy
Influence of microsatellite instability and KRAS and BRAF mutations on lymph node harvest in stage IâIII colon cancers
Lymph node (LN) harvest is influenced by several factors, including tumor genetics. Microsatellite instability (MSI) is associated with improved node harvest, but the association to other genetic factors is largely unknown. Research methods included a prospective series of stage IâIII colon cancer patients undergoing ex vivo sentinel-node sampling. The presence of MSI, KRAS mutations in codons 12 and 13, and BRAF V600E mutations was analyzed. Uni- and multivariate regression models for node sampling were adjusted for clinical, pathological and molecular features. Of 204 patients, 67% had an adequate harvest (âĽ12 nodes). Adequate harvest was highest in patients whose tumors exhibited MSI (79%; odds ratio [OR] 2.5, 95% confidence interval [CI] 1.2â4.9; P = 0.007) or were located in the proximal colon (73%; 2.8, 1.5â5.3; P = 0.002). In multiple linear regression, MSI was a significant predictor of the total LN count (P = 0.02). Total node count was highest for cancers with MSI and no KRAS/BRAF mutations. The independent association between MSI and a high LN count persisted for stage I and II cancers (P = 0.04). Tumor location in the proximal colon was the only significant predictor of an adequate LN harvest (adjusted OR 2.4, 95% CI 1.2â4.9; P = 0.01). An increase in the total number of nodes harvested was not associated with an increase in nodal metastasis. In conclusion, number of nodes harvested is highest for cancers of the proximal colon and with MSI. The nodal harvest associated with MSI is influenced by BRAF and KRAS genotypes, even for cancers of proximal location. Mechanisms behind the molecular diversity and node yield should be further explored.publishedVersio
Assessing a nurse-assisted eHealth intervention posthospital discharge in adult patients with non-communicable diseases: a protocol for a feasibility study
Introduction A growing number of patients with non-communicable diseases (NCDs), such as heart failure (HF) and colorectal cancer (CRC), are prone to comorbidity, a high rate of readmissions and complex healthcare needs. An eHealth intervention, however, could potentially ameliorate the increasing burdens associated with NCDs by helping to smoothen patient transition from hospital to home and by reducing the number of readmissions. This feasibility study therefore aims to assess the feasibility of a nurse-assisted eHealth intervention posthospital discharge among patients with HF and CRC, while also examining the preliminary clinical and behavioural outcomes of the intervention before initiating a full-scale randomised controlled trial. The recruitment ended in January 2023.
Methods and analysis Twenty adult patients with HF and 10 adult patients with CRC will be recruited from two university hospitals in Norway. Six hospital-based nurse navigators (NNs) will offer support during the transition phase from hospital to home by using a solution for digital remote care, Dignio Connected Care. The patients will use the MyDignio application uploaded to an iPad for 30 days postdischarge. The interactions between patients and NNs will then be assessed through direct observation and qualitative interviews in line with a think-aloud protocol. Following the intervention, semistructured interviews will be used to explore patientsâ experiences of eHealth support and NNsâ experiences of eHealth delivery. The feasibility testing will also comprise a post-test of the Post-System Usability Questionnaire and pretesting of patient-reported outcomes questionnaires, as well as an inspection of user data collected from the software.
Ethics and dissemination The study has been approved by the Norwegian Centre for Research Data (ID.NO: 523386). All participation is based on informed, written consent. The results of the study will be published in open-access, peer-reviewed journals and presented at international and national scientific conferences and meetings.publishedVersio
