Multicenter Prospective Cohort Study of the Patient-Reported Outcome Measures PRO-CTCAE and CAT EORTC QLQ-C30 in Major Abdominal Cancer Surgery (PATRONUS): A Student-Initiated German Medical Audit (SIGMA) Study

Postoperative Complications and Mobilization Following Major Abdominal Surgery With Versus Without Fitness Tracker-based Feedback (EXPELLIARMUS): A Student-led Multicenter Randomized Controlled Clinical Trial of the CHIR-Net SIGMA Study Group

OBJECTIVE

To determine whether daily postoperative step goals and feedback through a fitness tracker (FT) reduce the rate of postoperative complications after surgery.

BACKGROUND

Early and enhanced postoperative mobilization has been advocated to reduce postoperative complications, but it is unknown whether FT alone can reduce morbidity.

METHODS

EXPELLIARMUS was performed at 11 University Hospitals across Germany by the student-led clinical trial network SIGMA. Patients undergoing major abdominal surgery were enrolled, equipped with an FT, and randomly assigned to the experimental (visible screen) or control intervention (blackened screen). The experimental group received daily step goals and feedback through the FT. The primary end point was postoperative morbidity within 30 days using the Comprehensive Complication Index (CCI). All trial visits were performed by medical students in the hospital with the opportunity to consult a surgeon-facilitator who also obtained informed consent. After discharge, medical students performed the 30-day postoperative visit through telephone and electronic questionnaires.

RESULTS

A total of 347 patients were enrolled. Baseline characteristics were comparable between the 2 groups. The mean age of patients was 58 years, and 71% underwent surgery for malignant disease, with the most frequent indications being pancreatic, colorectal, and hepatobiliary malignancies. Roughly one-third of patients underwent laparoscopic surgery. No imputation for the primary end point was necessary as data completeness was 100%. There was no significant difference in the CCI between the 2 groups in the intention-to-treat analysis (mean±SD CCI experimental group: 23±24 vs. control: 22±22; 95% CI: -6.1, 3.7; P=0.628). All secondary outcomes, including quality of recovery, 6-minute walking test, length of hospital stay, and step count until postoperative day 7 were comparable between the 2 groups.

CONCLUSIONS

Daily step goals combined with FT-based feedback had no effect on postoperative morbidity. The EXPELLIARMUS shows that medical students can successfully conduct randomized controlled trials in surgery.

Long-term quality of life after resection of retroperitoneal soft tissue sarcoma

INTRODUCTION

Retroperitoneal soft tissue sarcoma (RPS) is characterized by high recurrence rates. Since complete tumor resection, often necessitating multivisceral resection, enables long-term survival in both primary and recurrent disease, health related quality of life (QoL) after RPS resection has attracted increasing interest. However, data regarding this topic is limited. Here, we multidimensionally assessed long-term QoL after RPS resection.

METHODS

Five previously validated (1. EORTC QLQ-C30, 2. WEMWBS, 3. FoP-Q-SF, 4. PC-PTSD, 5. Pro-CTCAE) were sent to patients having undergone resection of primary, recurrent and metastasized RPS at Heidelberg University Hospital between 10/2001 and 12/2020. Multivariable linear regression models were used to test associations between clinical/demographic variables and patient reported outcomes (PROs).

RESULTS

Questionnaires were answered by 127 patients (71% response rate). The median interval between RPS diagnosis and assessment of PROs was 80 months. The overall Global Health score was 64.1 and comparable to the general German population. RPS patients reported deficits regarding emotional and social functioning, whereas physical limitations were less pronounced. Besides diarrhea, abdominal symptoms were comparable to the overall population. Tumor recurrences, the number of surgeries, multivisceral resections or postoperative complications did not significantly affect long-term QoL ratings.

CONCLUSION

RPS patients rate their QoL relatively high, even after multiple and multivisceral resections. Psychosocial well-being should be monitored in follow-up sessions to offer tailored support if necessary, thus improving postoperative care.

Patient Perceptions of Decision-making and Quality-of-life Following Surgical Resection of Pancreatic Adenocarcinoma: A Mixed-methods Study

Pancreatic adenocarcinoma (PDAC) remains a highly lethal disease, with surgery, the only opportunity for cure, accompanied by high rates of morbidity. Understanding patients' lived experiences after surgical resection of PDAC is critical to knowing whether the decision to undergo surgery was worth it for these patients.

Methods

We performed a convergent, mixed-methods study with patients who underwent resection of PDAC between January 1, 2019, and January 8, 2020. Quantitative data (medical record review and 3 questionnaires) were analyzed using descriptive statistics. Qualitative data (semistructured interviews) were analyzed using the constant comparative method. Data were then compared for congruence.

Results

Eighteen of 22 eligible participants completed interviews and 11 completed questionnaires. Data collection occurred at a median of 14.2 months (IQR 11.6-16.3) from surgery. We identified 4 main themes. First, persistent negative symptoms were common for patients, but patients adapt to these and are satisfied with their "new normal." Second, patients have varied and continually evolving mindsets throughout their cancer journey. Third, despite decreased quality-of-life, patients have a high degree of satisfaction with their decision to pursue surgery. Finally, patients were okay with a passive role in decision-making around surgery. Despite variable involvement in decision-making and outcomes, no participants reported regret over the decision to pursue surgery.

Discussion

This nuanced account of patients' lived experiences following surgery for PDAC allows for an improved understanding of the impact of pancreatic resection on patients. Surgeons can use these data to improve preoperative counseling for patients with PDAC and help guide them to making the correct decisions about surgery.

Using Drain-Free Flap Fixation Techniques Versus Traditional Wound Closure With Drain Placement to Prevent Seroma Formation and Its Complications in Breast Cancer Patients Undergoing Mastectomy: A Systematic Review and Meta-analysis

During the past decade, there has been some controversy related to using flap fixation techniques instead of conventional wound closure methods and drain placement during mastectomy procedures. The purpose of our study was to address this controversy using a systematic review and meta-analysis of current published literature. Nineteen studies met our inclusion criteria. Our sample population consisted of 2,956 participants divided into two groups. The study group (SG) consisted of 1,418 individuals and the control group (CG) consisted of 1,538 participants. We found there was a significant reduction in the incidence of seroma formation (odds ratio [OR] = 0.35; 95% confidence interval, CI [0.3, 0.42]; p < .000) and surgical site infection (OR = 0.65; 95% CI [0.48, 0.88]; p = .006) in the SG compared with the CG. The length of hospital stay was also significantly reduced in the SG (0.59 days; 95% CI [0.73, 0.46]; χ 2 [6, N = 502] = 52.88; p < .000) compared with the CG. The results of our study show that using a flap fixation technique after mastectomy can decrease the patient's risk for seroma formation and surgical site infection while reducing their length of hospital stay. Further studies with longer follow-up periods are warranted to evaluate long-term complications associated with using a flap fixation technique compared with using conventional wound closure techniques and drain placement.

Impact of an Operating Room Nurse Preoperative Dialogue on Anxiety, Satisfaction and Early Postoperative Outcomes in Patients Undergoing Major Visceral Surgery-A Single Center, Open-Label, Randomized Controlled Trial

Background: Anxiety is common before surgery and known to negatively impact recovery from surgery. The aim of this study was to evaluate the impact of a preoperative nurse dialogue on a patient’s anxiety, satisfaction and early postoperative outcomes. Method: This 1:1 randomized controlled trial compared patients undergoing major visceral surgery after a semistructured preoperative nurse dialogue (interventional group: IG) to a control group (CG) without nursing intervention prior to surgery. Anxiety was measured with the autoevaluation scale State-Trait Anxiety Inventory (STAI, Y-form) pre and postoperatively. The European Organization for Research and Treatment of Cancer (EORTC) In-Patsat32 questionnaire was used to assess patient satisfaction at discharge. Further outcomes included postoperative pain (visual analogue scale: VAS 0−10), postoperative nausea and vomiting (PONV), opiate consumption and length of stay (LOS). Results: Over a period of 6 months, 35 participants were randomized to either group with no drop-out or loss to follow-up (total n = 70). The median score of preoperative anxiety was 40 (IQR 33−55) in the IG vs. 61 (IQR 52−68) in the CG (p < 0.001). Postoperative anxiety levels were comparable 34 (IQR 25−46) vs. 32 (IQR 25−44) for IG and CG, respectively (p = 0.579). The IG did not present higher overall satisfaction (90 ± 15 vs. 82.9 ± 16, p = 0.057), and pain at Day 2 was similar (1.3 ± 1.7 vs. 2 ± 1.9, p = 0.077), while opiate consumption, PONV levels and LOS were comparable. Conclusion: A preoperative dialogue with a patient-centered approach helped to reduce preoperative anxiety in patients undergoing major visceral surgery.
