Impact of pre-operative walking on post-operative bowel function in patients with gynecologic cancer

Outcome Heterogeneity in Prehabilitation Trials-Are We Comparing Apples and Oranges?

INTRODUCTION

Over the last decade, the number of prehabilitation randomised controlled trials (RCTs) has increased significantly. Therefore, this review aimed to describe the outcomes reported in prehabilitation RCTs in patients undergoing cancer surgery.

METHODS

A search was conducted in Embase, Allied and Complementary Medicine Database, The Cochrane Library, PsycINFO, MEDLINE, and Cumulated Index to Nursing and Allied Health Literature from inception to July 2021. We included RCTs evaluating the effectiveness of preoperative exercise, nutrition, and psychological interventions on postoperative complications and length of hospital stay in adult oncology patients who underwent thoracic and gastrointestinal cancer surgery. The verbatim outcomes reported in each article were extracted, and each outcome was assessed to determine whether it was defined and measured using a validated tool. Verbatim outcomes were grouped into standardized outcomes and categorized into domains. The quality of outcome reporting in each identified article was assessed using the Harman tool (score range 0-6, where 0 indicated the poorest quality).

RESULTS

A total of 74 RCTs were included, from which 601 verbatim outcomes were extracted. Only 110 (18.3%) of the verbatim outcomes were defined and 270 (44.9%) were labeled as either "primary" or "secondary" outcomes. Verbatim outcomes were categorized into 119 standardized outcomes and assigned into one of five domains (patient-reported outcomes, surgical outcomes, physical/functional outcomes, disease activity, and intervention delivery). Surgical outcomes were the most common outcomes reported (n = 71 trials, 95.9%). The overall quality of the reported outcomes was poor across trials (median score: 2.0 [IQR = 0.00-3.75]).

CONCLUSIONS

Prehabilitation RCTs display considerable heterogeneity in outcome reporting, and low outcome reporting quality. The development of standardized core outcome sets may help improve article quality and enhance the clinical utility of prehabilitation following cancer surgery.

The impact of short-term multimodal prehabilitation on functional capacity in patients with gynecologic malignancies during the perioperative period: A prospective study

PURPOSE

To explore the effect of a short-term, hospital-based, multimodal preoperative prehabilitation intervention on perioperative functional ability of patients with gynecological malignant tumors.

METHODS

According to the order in which they underwent surgery, 97 patients were divided into the control group (48 cases) and the intervention group (49 cases). The control group was given routine preoperative guidance, whereas the intervention group was given short-term multimodal prehabilitation guidance on the basis of the control group intervention. The 6-min walk test was performed on the day of admission to the hospital, the day before surgery, and the 30th day after surgery.

RESULTS

Compared with the control group, the intervention group had significantly better 6-min walk distance and superior physical and psychological status on the day before surgery and the 30th day after surgery (P < 0.001). For three consecutive days after surgery, the quality of recovery in the intervention group was significantly higher than that in the control group (P < 0.001), and the first ambulation time and exhaust time were achieved earlier in the intervention group than in the control group (P < 0.05).

CONCLUSION

The preoperative intervention group showed improved preoperative exercise ability and reduced anxiety in patients with gynecological cancer. Furthermore, this intervention improved the overall health of patients and accelerated their postoperative recovery.

Effect of abdominal hot pack application on gastrointestinal motility recovery after comprehensive gynecologic staging surgery

OBJECTIVE

To evaluate whether abdominal hot water pack application improves gastrointestinal motility following gynecological oncology surgery.

METHODS

The study was registered at ClinicalTrials.gov (NCT04833699). (https://clinicaltrials.gov/ct2/show/NCT04833699?cond=NCT04833699&draw=2&rank=1). In this randomized controlled trial, participants were randomly assigned (1:1) to the hot water pack group (standardized enhanced recovery protocols plus rubber water bag with a fluffy cover filled with boiled tap water [80°C] and placed on the abdomen at 3, 6, 9, and 12 h postoperatively for 30 min each time) or the control group (standardized enhanced recovery protocols). A subumbilical or supraumbilical vertical midline incision was made to perform staging surgery procedures, including hysterectomy, salpingo-oophorectomy with retroperitoneal lymphadenectomy. The primary outcome was the time to first passage of flatus from the end of the staging procedure.

RESULTS

In total, 121 women were randomized to the control (n = 62) or hot water pack (n = 59) group. The use of an abdominal hot water pack significantly reduced the mean time to passing first flatus (25.2 ± 3.6 vs. 30.6 ± 3.9 h; hazard ratio [HR] = 4.4; 95% confidence interval [CI]: 2.8-7.1; P < 0.0001), mean time to first bowel movements (28.4 ± 4.0 vs. 34.4 ± 4.5 h; HR = 4.9; 95% CI: 3.0-7.9; P < 0.0001), mean time to first defecation (33.4 ± 4.9 vs. 41.0 ± 7.6 h; HR = 4.3; 95% CI: 2.1-6.8; P < 0.0001), and mean time to tolerating solid diet (2.1 ± 0.6 vs. 2.8 ± 1.0 days; HR = 4.4; 95% CI: 2.2-8.7; P < 0.0001) compared to the control group. The postoperative ileus incidence was significantly lower in the hot water pack group (3.4%) than the control group (16.1%) (P = 0.01).

CONCLUSION

Abdominal hot water pack application improved gastrointestinal function recovery in women following surgical staging procedures for gynecological malignancy.

Prolonged preoperative sedentary time is a risk factor for postoperative ileus in patients with colorectal cancer: a propensity score-matched retrospective study

PURPOSE

This study aimed to investigate the association between prolonged preoperative sedentary time (ST) and postoperative ileus (POI) after adjusting for confounders in patients with colorectal cancer (CRC).

METHODS

This single-center retrospective study enrolled 155 consecutive patients who underwent surgery for primary CRC. A diagnosis of POI was made by the surgeons if the Clavien-Dindo classification (CD) grade is ≥ 2 within 30 days after surgery. Preoperative ST was assessed using the International Physical Activity Questionnaire usual week short version (Japanese version). Patients were classified into two groups (ST < 6 h/day and ST ≥ 6 h/day) based on results from the questionnaire, and data were analyzed using a propensity score-matching strategy to adjust for confounders. In addition, receiver operating characteristic (ROC) curve analysis was performed to identify the optimal cutoff value of preoperative ST for predicting POI.

RESULTS

Of the 155 patients, 134 were included in the analysis. POI occurred in 16 (11.9%) patients of overall patients and 11 (12.5%) of the 88 matched patients. The logistic regression analysis after propensity score-matching showed that prolonged preoperative ST (ST ≥ 6 h/day) was associated with POI (odds ratio 5.40 (95% confidence interval: 1.09 - 26.60), p = 0.038). The ROC curve analysis indicated that the optimal cutoff value of preoperative ST for predicting POI was 6 h/day.

CONCLUSION

Prolonged preoperative ST is a risk factor for POI in patients with CRC. Therefore, reducing preoperative ST may play an important role in preventing POI.

Allied health professional's self-reported competences and confidence to deliver physical activity advice to cancer patients at a single Centre in England

PURPOSE

Allied Health Professionals (AHPs) are well placed to deliver physical activity advice but this is currently not routine clinical practice. Increasing evidence demonstrates physical activity can improve quality-of-life for people affected by cancer, enable behaviour change, improve survival and reduce long-term treatment effects. We aimed to understand AHPs' current knowledge and practice in advising about physical activity.

MATERIALS AND METHODS

AHPs' self-reported knowledge, competency and training needs in managing physical effects of cancer, and the merits of physical activity data were collected via an online survey. The survey link was cascaded electronically to all NHS and NHS-affiliated AHPs working across several generic and non-cancer-specific healthcare interfaces across one city in England.

RESULTS

Eighty AHPs responded. Forty-one percent of AHPs had patients with current or past diagnoses of cancer. Overall, AHPs reported low confidence in giving physical activity advice, with physiotherapists the most confident. 60% of respondents identified training needs concerning the impact of cancer.

CONCLUSIONS

Although the merits of physical activity for people affected by cancer is clearly evidenced, low levels of AHP confidence and competence in discussing this topic limit patients' awareness and access to services. Addressing this confidence and competence has potential to improve patient outcome.

Exercise, Diet, and Weight Management During Cancer Treatment: ASCO Guideline

PURPOSE

To provide guidance on exercise, diet, and weight management during active cancer treatment in adults.

METHODS

A systematic review of the literature identified systematic reviews and randomized controlled trials evaluating the impact of aerobic and resistance exercise, specific diets and foods, and intentional weight loss and avoidance of weight gain in adults during cancer treatment, on quality of life, treatment toxicity, and cancer control. PubMed and the Cochrane Library were searched from January 2000 to May 2021. ASCO convened an Expert Panel to review the evidence and formulate recommendations.

RESULTS

The evidence base consisted of 52 systematic reviews (42 for exercise, nine for diet, and one for weight management), and an additional 23 randomized controlled trials. The most commonly studied types of cancer were breast, prostate, lung, and colorectal. Exercise during cancer treatment led to improvements in cardiorespiratory fitness, strength, fatigue, and other patient-reported outcomes. Preoperative exercise in patients with lung cancer led to a reduction in postoperative length of hospital stay and complications. Neutropenic diets did not decrease risk of infection during cancer treatment.

RECOMMENDATIONS

Oncology providers should recommend regular aerobic and resistance exercise during active treatment with curative intent and may recommend preoperative exercise for patients undergoing surgery for lung cancer. Neutropenic diets are not recommended to prevent infection in patients with cancer during active treatment. Evidence for other dietary and weight loss interventions during cancer treatment was very limited. The guideline discusses special considerations, such as exercise in individuals with advanced cancer, and highlights the critical need for more research in this area, particularly regarding diet and weight loss interventions during cancer treatment.Additional information is available at www.asco.org/supportive-care-guidelines.

Bacillus coagulans TBC169 probiotics for the recovery of intestinal function after gynecological laparoscopic surgery: a randomized, placebo-controlled trial

BACKGROUND

Evidence suggests that Bacillus coagulans TBC169 can improve intestinal motility.

AIM

To investigate the effectiveness and safety of Bacillus coagulans TBC169 probiotics in promoting the recovery of intestinal function after gynecological laparoscopic surgery.

METHOD

Patients who underwent laparoscopic surgeries due to gynecological diseases were randomly assigned to the high-dose, conventional-dose, and the placebo-control groups (1:1:1 ratio). The primary outcome was the time to the first passage of flatus time (FFT). Secondary outcomes were the time to the first defecation (FDT), the time to the first bowel sounds (TFBS), the duration of hospital stay (DHS), and the incidence of postoperative adverse events (AEs).

RESULTS

Compared to the placebo-control group, shorter FFT values were observed in the conventional-dose (23.15 h vs. 29.10 h, P < 0.05) and high-dose (19.15 h vs. 29.10 h, P < 0.001) groups. Similar trends were observed regarding TFBS in the conventional-dose (18.50 h vs. 21.10 h, P < 0.05) and high-dose (15.20 h vs. 21.10 h, P < 0.001) groups. There were no significant differences in FFT and TFBS between the intervention groups. Compared to the placebo-control group, lower incidences of postoperative adverse events were observed in the conventional-dose (12.50% vs. 40.00%, P < 0.05) and the high-dose (5.00% vs. 40.00%, P < 0.001) groups. However, there were no significant differences between these intervention groups.

CONCLUSION

Bacillus coagulans TBC169 probiotics can accelerate intestinal function recovery, and reduce postoperative adverse events in patients after gynecological laparoscopic surgery. The study protocol was registered at the Chinese Clinical Trial Registry (ChiCTR2200059518).

The effects of fentanyl, oxycodone, and butorphanol on gastrointestinal function in patients undergoing laparoscopic hysterectomy: a prospective, double-blind, randomized controlled trial

Background

Perioperative opioid use is associated with postoperative bowel dysfunction, which causes longer hospital stay and higher healthcare costs. This study aimed to investigate the effect of the equivalent doses of fentanyl, oxycodone, and butorphanol on bowel function in patients undergoing laparoscopic hysterectomy.

Methods

In this randomized controlled trial, 135 patients undergoing laparoscopic hysterectomy received postoperative intravenous patient-controlled analgesia (IV-PCA) with fentanyl 8.3 μg/kg, butorphanol 0.16 mg/kg, and oxycodone 0.5 mg/kg (1: 20: 60), respectively. The primary outcome measure was the recovery of bowel function. We also evaluated and recorded the following nine indicators: pain score, sedation level, leukocyte count, percentage of neutrophils, plasma potassium levels, time to first ambulation, postoperative side effects, patients' satisfaction, and postoperative hospital length of stay.

Results

The mean time to flatus was significantly prolonged in Group B (45.2 ± 11.6 h) compared with Group F (33.1 ± 11.2 h, P < 0.001) and Group O (36.2 ± 10.9 h, P = 0.001). The incidence of somnolence and dizziness prove higher in Group B (P < 0.001). No statistical difference was observed in the mean time to tolerate oral diet, time to defecation, analgesic outcome, satisfaction score, time to first ambulation, and postoperative hospital length of stay.

Conclusions

Compared with fentanyl and oxycodone, butorphanol prolonged the recovery of bowel function with more severe somnolence and dizziness, suggesting that butorphanol is not well suitable for IV-PCA in patients undergoing laparoscopic hysterectomy.

Non-pharmacological interventions for the prevention of postoperative ileus after gynecologic cancer surgery

Postoperative ileus (POI) is characterized by impaired gastrointestinal motility after surgery. POI is a major concern for surgeons because it increases hospital stay, the cost of care, and postoperative morbidity in patients who have undergone extensive gynecological oncological surgery. Although several interventions have been proposed and investigated, no effective treatment for the prevention and management of POI has been established. The present review summarizes the current evidence on non-pharmacological interventions, including coffee consumption and chewing gum, used to prevent and treat POI. We obtained studies from MEDLINE, Cochrane Database of Systematic Reviews, ISI Web of Science, and SCOPUS databases.

Risk factors of postoperative ileus following laparoscopic radical cystectomy and developing a points-based risk assessment scale

Background

Postoperative ileus (POI) is one of the most common complications after laparoscopic radical cystectomy (LRC). Albeit its high incidence, its risk factors are obscure, and few studies have attempted to explore them. Meanwhile, risk-assessing tools for predicting its happening are lacking.

Methods

Clinical data of 197 patients who underwent LRC between March 2014 and October 2019 were retrospectively collected. All cases of POI were identified and double-checked. Data pertaining to the following categories were extracted as well: patients' general characteristics, preoperative laboratory tests results and preparations, intraoperative and postoperative general items, pathological results. The correlation between candidate risk factors and ileus was analyzed by multivariable binary logistic regression. Clinical and pathophysiological explanations for those results were explored. Finally, a points-based prediction model was developed and validated for predicting the happening of POI.

Results

A total of 63 out of 197 patients (31.98%) suffered from POI. Multivariate logistic regression analysis showed chronic constipation, increased dosage of laxative, elevated preoperative serum creatinine level, delayed postoperative ambulation, intestine-related urine derivations were statistically significant for developing POI (P<0.05). No significant differences were found between POI and age, gender, body mass index (BMI), antibiotics, hypertension, diabetes, smoking, hard-drinking, preoperative hemoglobin level, preoperative albumin level, history of previous abdominal surgery, surgery time, intraoperative blood loss, blood transfusion, tumor size, lymph nodes yields, TNM staging and intensive care unit hospitalization. An external cohort had been used for testing the validation of the assessment scale, and the results were promising.

Conclusions

Early recognition is of great importance in protecting vulnerable patients from developing POI, knowing the above-mentioned risk factors and using the assessment scale should help to screen them better. Cases from diverse backgrounds might contribute to a more accurate and complete scale.

Coffee consumption for recovery of intestinal function after laparoscopic gynecological surgery: A randomized controlled trial

BACKROUND

To investigate the effect of postoperative coffee consumption on bowel motility after laparoscopic gynecological surgery.

MATERIALS AND METHODS

In this randomized controlled trial, patients were allocated postoperatively to 3 cups of either coffee or warm water at 6, 12, or 18 h after the operation. Total hysterectomy and bilateral salpingectomy were performed on all patients. In addition, a salpingo-oophorectomy and systematic pelvic with/without para-aortic lymphadenectomy were performed according to clinical indications. The primary endpoint was time to the first passage of flatus after surgery.

RESULTS

A total of 96 patients were enrolled; 49 patients were assigned to the coffee group, and 47 were enrolled in the control group (warm water). The median time to flatus (19 [13-35] vs. 25 [15-42] h; hazard ratio [HR] 1.9, 95% confidence interval [CI], 1.2-2.9; P = 0.0009), median time to defecation (30 [22-54] vs. 38 [26-65] h, HR 2.4, 95% CI, 1.5-3.8; P < 0.0001), and mean time to tolerate food (2 [2-5] vs. 3 [2-8] days, HR 1.5, 95% CI, 1.02-2.3; P = 0.002) were decreased significantly in patients who consumed coffee compared with the control subjects. Postoperative ileus was observed in seven patients (14.9%) in the control group and one patient (2.0%) in the coffee group (P = 0.02). No adverse events were attributed to coffee consumption.

CONCLUSION

Postoperative coffee intake after laparoscopic gynecological surgery hastened the recovery of gastrointestinal function by reducing the time to the first passage of flatus, time to the first defecation, and time to tolerate a solid diet. This simple, cheap, and well-tolerated treatment merits routine use alongside other existing enhanced recovery pathways in the postoperative setting.
