Continuous transversus abdominis plane blocks in patients undergoing minimally invasive colorectal surgery: a randomized pilot study

The impact of sleep interventions combined with enhanced nutritional support on sleep quality, nutritional status, pain management, psychological well-being, and quality of life in postoperative colon cancer patients

OBJECTIVE

To investigate the synergistic effects of combined sleep interventions and enhanced nutritional support on postoperative recovery in colon cancer patients, with a focus on sleep quality, nutritional status, pain management, psychological well-being, and quality of life.

METHODS

This randomized controlled trial included 290 postoperative colon cancer patients admitted to the First Affiliated Hospital of Soochow University between May 2021 and May 2023. Participants were randomized into two groups: the intervention group, which received standard care supplemented with sleep and nutritional interventions, and the control group, which received standard care alone. Outcomes were assessed pre- and post-intervention, including the Pittsburgh Sleep Quality Index (PSQI), nutritional markers (serum albumin, prealbumin, body weight, etc.), Visual Analog Scale (VAS) for pain, Self-Rating Anxiety and Depression Scales (SAS, SDS), and EORTC QLQ-C30 quality of life scores.

RESULTS

The intervention group demonstrated significantly greater improvements across all assessed domains compared to the control group ( P < 0.005 after Bonferroni correction). Sleep quality (PSQI: 7.81 vs. 10.43, d = 0.81) and nutritional markers (e.g., prealbumin: 230.19 mg/L vs. 188.01 mg/L, d = 1.21 ) improved markedly. Similarly, reductions in pain (VAS: 2.65 vs. 5.19,d = 1.09 ), anxiety (SAS: 42.03 vs. 49.45, d = 0.88), and depression (SDS: 38.17 vs. 49.77,d = 1.02 ) were observed. Quality of life scores significantly increased in the intervention group compared to the control group (EORTC QLQ-C30: 99.29 vs. 88.41, d = 0.92).

CONCLUSION

The combined intervention of sleep enhancement and nutritional support significantly accelerated postoperative recovery in colon cancer patients, demonstrating synergistic effects that improved physical, psychological, and quality-of-life outcomes. These findings underscore the value of integrating multifaceted interventions into standard postoperative care to optimize recovery trajectories and overall well-being.

United States-Based Colorectal Cancer Surgical Trials Lack Representation and Adequate Reporting of Racially and Ethnically Diverse Participants: Systematic Review and Regression Analysis

BACKGROUND

Despite the established National Institute of Health Revitalization Act, which aims to include ethnic and racial minority representation in surgical trials, racial and ethnic enrollment disparities persist.

OBJECTIVE

To assess the proportion of patients from minority races and ethnicities that are included in colorectal cancer surgical trials and reporting characteristics.

DATA SOURCES

Search was performed using MEDLINE (Ovid), Embase, Web of Science, and Cochrane Central.

STUDY SELECTION

Inclusion criteria included 1) trials performed in the United States between January 1, 2000, and May 30, 2022; 2) patients with colorectal cancer diagnosis; and 3) surgical intervention, technique, or postoperative outcome. Trials evaluating chemotherapy, radiotherapy, or other nonsurgical interventions were excluded.

INTERVENTIONS

Pooled proportion and regression analysis was performed to identify the proportion of patients by race and ethnicity included in surgical trials and the association of year of publication and funding source.

MAIN OUTCOME MEASURES

Proportion of trials reporting race and ethnicity and proportion of participants by race and ethnicity included in surgical trials.

RESULTS

We screened 10,673 unique publications, of which 80 were examined in full text. Fifteen studies met our inclusion criteria. Ten (66.7%) trials did not report race, 3 reported races as a proportion of White participants only, and 3 reported 3 or more races. There was no description of ethnicity in 11 (73.3%) trials, with 2 describing "non-Caucasian" as ethnicity and 2 describing only Hispanic ethnicity. Pooled proportion of White participants was 81.3%, of Black participants was 6.2%, of Asian participants was 3.6%, and of Hispanic participants was 3.5%.

LIMITATIONS

A small number of studies was identified that reported racial or ethnic characteristics of their participants.

CONCLUSIONS

Both race and ethnicity are severely underreported in colorectal cancer surgical trials. To improve outcomes and ensure the inclusion of vulnerable populations in innovative technologies and novel treatments, reporting must be closely monitored.

PROcedure-SPECific postoperative pain management guideline for laparoscopic colorectal surgery: A systematic review with recommendations for postoperative pain management

Colorectal cancer is the second most common cancer diagnosed in women and third most common in men. Laparoscopic resection has become the standard surgical technique worldwide given its notable benefits, mainly the shorter length of stay and less postoperative pain. The aim of this systematic review was to evaluate the current literature on postoperative pain management following laparoscopic colorectal surgery and update previous procedure-specific pain management recommendations. The primary outcomes were postoperative pain scores and opioid requirements. We also considered study quality, clinical relevance of trial design, and a comprehensive risk-benefit assessment of the analgesic intervention. We performed a literature search to identify randomised controlled studies (RCTs) published before January 2022. Seventy-two studies were included in the present analysis. Through the established PROSPECT process, we recommend basic analgesia (paracetamol for rectal surgery, and paracetamol with either a nonsteroidal anti-inflammatory drug or cyclo-oxygenase-2-specific inhibitor for colonic surgery) and wound infiltration as first-line interventions. No consensus could be achieved either for the use of intrathecal morphine or intravenous lidocaine; no recommendation can be made for these interventions. However, intravenous lidocaine may be considered when basic analgesia cannot be provided.

Transversus abdominis plane block for laparoscopic colorectal surgery: A meta-analysis of randomised controlled trials

BACKGROUND

The effectiveness of transversus abdominis plane block (TAP) on pain management after laparoscopic colorectal surgery (CRS) remains unclear since the only relevant meta-analysis on this topic did not separate laparoscopic CRS from open CRS. The aim of the study was to compare the analgesic efficacy and safety of TAP with non-TAP in patients undergoing laparoscopic CRS.

METHODS

Four databases were searched for randomized controlled trials (RCTs) on this topic using relevant keywords. Two authors independently completed evidence selection, data extraction, and critical appraisal. Available data were pooled in the random-effects model, and point estimates with 95% confidence interval (CI) were reported for postoperative pain at rest and on coughing, opioid consumption, length of hospital stay, and adverse events.

RESULTS

A total of 14 RCTs (n = 1216) contributed to the present synthesis. Pooled result showed that patients in the TAP group had lower pain at rest than those in the non-TAP group at postoperative 2-h (mean difference [MD] = -1.42; P < 0.05), 4-h (MD = -0.97; P < 0.05), 12-h (MD = -0.75; P < 0.05), and 24-h (MD = -0.61; P < 0.05). Patients in the TAP group also had lower postoperative pain on coughing than those in the non-TAP group on the first day (MD = -1.02; P < 0.05). Moreover, TAP had lesser postoperative opioid consumption than non-TAP (standardized mean difference, -0.26; P < 0.05; I-square = 20%), and there were non-significant differences in hospital stay and adverse event between the two groups.

CONCLUSION

Intraoperative TAP is a safe and feasible pain management for laparoscopic CRS, particularly it is recommended when patient-controlled analgesia is not delivered. Therefore, laparoscopic TAP block might be a favorable administered strategy.
