Optimized perioperative management (fast-track, ERAS) to enhance postoperative recovery in elective colorectal surgery

Mitigating Medical Adverse Events Following Spinal Surgery: The Effectiveness of a Postoperative Quality Improvement (QI) Care Bundle

BACKGROUND AND OBJECTIVES

Spine surgery is associated with a high incidence of postoperative medical adverse events (AEs). Many of these events are considered "minor" though their cost and effect on outcome may be underestimated. We sought to examine the clinical and cost-effectiveness of a postoperative quality improvement (QI) care bundle in mitigating postoperative medical AEs in adult surgical spine patients.

METHODS

We collected 14-year prospective observational interrupted time series (ITS) with two historical cohorts: 2006 to 2008, pre-implementation of the postoperative QI care bundle; and 2009 to 2019, post-implementation of the postoperative QI care bundle. Adverse Events were identified and graded (Minor I and II) using the previously validated Spine AdVerse Events Severity (SAVES) system. Pearson Correlation tested for changes across patient and surgical variables. Adjusted segmented regression estimated the effect of the postoperative QI care bundle on the annual and absolute incidences of medical AEs between the two periods. A cost model estimated the annual cumulative cost savings through preventing these "minor" medical AEs.

RESULTS

We included 13,493 patients over the study period with a mean of 964 per year (SD ± 73). Mean age, mean Charlson Comorbidity Index (CCI), and mean spine surgical invasiveness index (SSII) increased from 48.4 to 58.1 years; 1.7 to 2.6; and 15.4 to 20.5, respectively (p < 0.001). Unadjusted analysis confirmed a significant decrease in the annual number of all medical AEs (p < 0.01). When adjusting for age, CCI and SSII, segmented regression demonstrated a significant absolute reduction in the annual incidence of cardiac, pulmonary, nausea and medication-related AEs by 9.58%, 7.82%, 11.25% and 15.01%, respectively (p < 0.01). The postoperative QI care bundle was not associated with reducing the annual incidence of delirium, electrolyte levels or GI AEs. Annual projected cost savings for preventing Grade I and II medical AEs were $1,808,300 CAD and $11,961,500 CAD.

CONCLUSION

Postoperative QI care bundles are effective for improving patient care and preventing medical care-related AEs, with significant cost savings. Postoperative QI care bundles should be tailored to the specific vulnerability of the surgical population for experiencing AEs.

Applying enhanced recovery after surgery protocols in a patient with a giant spleen: a case report

Although splenomegaly is a common finding in several diseases, massive splenomegaly is rare. Patients with massive splenomegaly often present with a complex clinical picture. This case report describes a 72-year-old female with a complex medical history. Fifteen years ago, she was diagnosed with primary myelofibrosis, which subsequently led to progressive abdominal enlargement and bloating over the past 5 years. Recently, she developed edema in her limbs, accompanied by dizziness, shortness of breath, and fatigue. A massive splenomegaly was discovered during her hospitalization. Additionally, the patient has a history of Crohn's disease, gout, renal insufficiency, and hypertension. Laboratory results reveal severe anemia and thrombocytopenia. Abdominal CT scans confirm the enlarged spleen and show ascites. She was treated by a multidisciplinary team comprising several departments. Even after a period of comprehensive treatment, the symptoms of massive splenomegaly did not significantly improve. Thus, the patient underwent an open surgical excision of the giant spleen. The weight of the giant spleen was 5.0 kg. During the perioperative period, Enhanced Recovery After Surgery (ERAS) protocols were applied to facilitate recovery. Her recovery was uneventful, and she was able to resume her regular daily routine shortly after the procedure. This report presented a complex and rare case of massive splenomegaly, and underscored that a proper medical and nursing care is the key to better recovery.

Drain versus no drain in elective open incisional hernia operations: a registry-based analysis with 39,523 patients

PURPOSE

Elective open incisional hernia operations are a frequently performed and complex procedure. Prophylactic drainage is widely practised to prevent local complications, but nevertheless the benefit of surgical drain placement remains a controversially discussed subject. Objective of this analysis was to evaluate the current status of patient care in clinical routine and outcome in this regard.

METHODS

The study based on prospectively collected data of the Herniamed Register. Included were all patients with elective open incisional hernia between 1/2005 and 12/2020 and completed 1-year follow-up. Multiple linear and logistic regression analysis was performed to assess the relation of individual factors to the outcome variables.

RESULTS

Analysed were data from 39,523 patients (28,182 with drain, 11,341 without). Patients with drain placement were significantly older, had a higher BMI, more preoperative risk factors, and a larger defect size. Drained patients furthermore showed a significant disadvantage in the outcome parameters intraoperative complications, general complications, postoperative complications, complication-related reoperations, and pain at the 1-year follow-up. No significant difference was observed with respect to the recurrent rate.

CONCLUSION

With 71.3%, the use of surgical drainages has a high level of acceptance in elective open incisional hernia operations. The worse outcome of patients is associated with the use of drains, independent of other influencing factors in the model such as patient or surgical characteristics. The use of drains may be a surrogate parameter for other unobserved confounders.

Multimodal prehabilitation and postoperative outcomes in upper abdominal surgery: systematic review and meta-analysis

The impact of multimodal prehabilitation on postoperative complications in upper abdominal surgeries is understudied. This review analyzes randomized trials on multimodal prehabilitation with patient and hospital outcomes. MEDLINE, Embase, CINAHL, and Cochrane CENTRAL were searched for trials on prehabilitation before elective (non-emergency) abdominal surgery. Two reviewers independently screened studies, extracted data, and assessed study quality. Primary outcomes of interest were postoperative pulmonary complications (PPCs) and all-cause complications; secondary outcomes included hospital and intensive care length of stay. A meta-analysis with random-effect models was performed, and heterogeneity was evaluated with I-square and Cochran's Q test. Dichotomous variables were reported in log-odds ratio and continuous variables were presented as mean difference. Ten studies (total 1503 patients) were included. Odds of developing complications after prehabilitation were significantly lower compared to various control groups (- 0.38 [- 0.75- - 0.004], P = 0.048). Five studies described PPCs, and participants with prehabilitation had decreased odds of PPC (- 0.96 [- 1.38- - 0.54], P < 0.001). Prehabilitation did not significantly reduce length of stay, unless exercise was implemented; with exercise, hospital stay decreased significantly (- 0.91 [- 1.67- - 0.14], P = 0.02). Multimodal prehabilitation may decrease complications in upper abdominal surgery, but not necessarily length of stay; research should address heterogeneity in the literature.

Longitudinal dynamics of gut bacteriome and mycobiome interactions pre- and post-visceral surgery in Crohn's disease

Introduction

Alterations of the gut microbiome are involved in the pathogenesis of Crohn's disease (CD). The role of fungi in this context is unclear. This study aimed to determine postoperative changes in the bacterial and fungal gut communities of CD patients undergoing intestinal resection, and to evaluate interactions between the bacteriome and mycobiome and their impact on the patients' outcome.

Methods

We report a subgroup analysis of a prospective cohort study, focusing on 10 CD patients whose fecal samples were collected for bacterial 16S rRNA and fungal ITS2 genes next-generation sequencing the day before surgery and on the 5th or 6th postoperative day.

Results

No significant differences in bacterial and fungal diversity were observed between preoperative and postoperative stool samples. By in-depth analysis, significant postoperative abundance changes of bacteria and fungi and 17 interkingdom correlations were detected. Network analysis identified 13 microbial clusters in the perioperative gut communities, revealing symbiotic and competitive interactions. Relevant factors were gender, age, BMI, lifestyle habits (smoking, alcohol consumption) and surgical technique. Postoperative abundance changes and identified clusters were associated with clinical outcomes (length of hospital stay, complications) and levels of inflammatory markers.

Conclusions

Our findings highlight the importance of dissecting the interactions of gut bacterial and fungal communities in CD patients and their potential influence on postoperative and disease outcomes.

Enhancing surgical precision: unveiling the impact of preoperative colonoscopy in anal fistula patients

BACKGROUND

Anal fistula is a common benign anorectal disease that often requires surgical intervention for effective treatment. In recent years, preoperative colonoscopy as a diagnostic tool in patients with anal fistula has garnered increasing attention due to its potential clinical application value. By investigating underlying inflammatory bowel disease (IBD), polyps, and other abnormalities, preoperative colonoscopy can offer insights to refine surgical strategies and improve patient outcomes.

METHODS

This retrospective study focused on 1796 patients with various benign anorectal diseases who underwent preoperative intestinal endoscopy and met surgical criteria within the preceding three years at the First Affiliated Hospital of Guizhou University of Traditional Chinese Medicine. Among these patients, 949 diagnosed with anal fistula comprised group A, while 847 patients without anal fistula were assigned to group B for comparison. The investigation encompassed an analysis of general patient information, endoscopic findings, polyp histopathology, distribution of bowel inflammation sites, and results of inflammatory bowel disease assessments between the two patient cohorts. A subgroup analysis was also conducted on 2275 anal fistula patients with no surgical contraindications. This subgroup was categorized into Group A (949 patients who underwent preoperative intestinal endoscopy) and Group C (1326 patients who did not undergo preoperative colonoscopy). The study compared the rates of detecting endoscopic lesions and IBD-related findings between the two subgroups.

RESULTS

The study initially confirmed the comparability of general patient information between groups A and B. Notably, the abnormal detection rate in group A was significantly higher than in group B (P < 0.01). In terms of endoscopic findings, the anal fistula group (group A) exhibited higher rates of detecting bowel inflammation, inflammatory bowel disease, and polyps compared to the non-anal fistula group (group B) (P < 0.05). The distribution of inflammation locations indicated higher detection rates in the terminal ileum, ileocecal region, and ascending colon for group A compared to group B (P < 0.05). Although the incidence of IBD in group A was higher than in group B, this difference did not reach statistical significance (P > 0.05). Subsequently, the analysis of the subgroup (groups A and C) revealed a significant disparity in intestinal endoscopic detection rates (P < 0.01) and statistically significant differences in detecting IBD (P < 0.05) and Crohn's disease (P < 0.05) between the two anal fistula subgroups.

CONCLUSIONS

The findings of this study underscore the substantial clinical value of preoperative colonoscopy in the comprehensive evaluation of patients with anal fistula. Preoperative colonoscopy aids in ruling out localized perianal lesions caused by underlying inflammatory bowel disease, thereby mitigating the likelihood of missed diagnoses and enhancing treatment outcomes. This research highlights the importance of incorporating preoperative colonoscopy as a valuable diagnostic tool in managing anal fistula patients.

Enhanced recovery programme after colorectal surgery in high-income and low-middle income countries: a systematic review and meta-analysis

BACKGROUND

Enhanced recovery after surgery (ERAS) protocols strive to optimise outcomes following elective surgery; however, there is a dearth of evidence to support its equitable application and efficacy internationally.

MATERIALS AND METHODS

The authors performed a systematic review and meta-analysis of studies on the uptake and impact of ERAS with the aim of highlighting differences in implementation and outcomes across high-income countries (HICs) and low-middle income countries (LMICs). The primary outcome was characterisation of global ERAS uptake. Secondary outcomes included length of hospital stay (LOS), 30-day readmission, 30-day mortality and postoperative complications.

RESULTS

Three hundred thirty-seven studies with considerable heterogeneity were included in the analysis (291 from HICs, and 46 from LMICs) with a total of 110 190 patients. The weighted median number of implemented elements were similar between HICs and LMICs ( P =0·94), but there was a trend towards greater uptake of less affordable elements across all aspects of the ERAS pathway in HICs. The mean LOS was significantly shorter in patient cohorts in HICs (5·85 days versus 7·17 days in LMICs, P <0·001). The 30-day readmission rate was higher in HICs (8·5 vs. 4·25% in LMICs, P <0·001, but no overall world-wide effect when ERAS compared to controls (OR 1·00, 95% CI: 0·88-1·13). There were no reported differences in complications ( P =0·229) or 30-day mortality ( P =0·949).

CONCLUSION

Considerable variation in the structure, the implementation and outcomes of ERAS exists between HICs and LMICs, where affordable elements are implemented, contributing towards longer LOS in LMICs. Global efforts are required to ensure equitable access, effective ERAS implementation and a higher standard of perioperative care world-wide.
