Persisting anorectal dysfunction after rectal cancer surgery

Colonic J-pouch versus side-to-end anastomosis for rectal cancer: a systematic review and meta-analysis of randomized controlled trials

Background

This study aims to compare colonic J-pouch and side-to-end anastomosis for rectal cancer in terms of surgical and bowel functional outcomes and quality of life (QoL).

Methods

A systematic literature search was performed in PubMed, Embase and Cochrane. The last search was performed on March 28, 2021. All randomized controlled trials comparing colonic J-pouch with side-to-end anastomosis for rectal cancer were enrolled. The main outcomes were bowel functional outcomes and QoL. The secondary outcomes were surgical outcomes including operative time, postoperative hospital stay, complications, and mortality.

Results

Nine articles incorporating 7 trials with a total of 696 patients (330 by J-pouch and 366 by side-to-end) were enrolled in this meta-analysis. The bowel functional outcomes were comparable between J-pouch and side-to-end groups in terms of stool frequency, urgency, and incomplete defecation at the short term (< 8 months), medium term (8–18 months), and long term (> 18 months) follow up evaluations. No difference was observed between groups with regards to QoL (SF-36: physical function, social function, and general health perception). Besides, surgical outcomes were also similar in two groups.

Conclusion

The currently limited evidence suggests that colonic J-pouch and side-to-end anastomosis are comparable in terms of bowel functional outcomes, QoL, and surgical outcomes. Surgeons may choose either of the two techniques for anastomosis. A large sample randomized controlled study comparing colonic J-pouch and side-to-end anastomosis for rectal cancer is warranted.

The Relationship Between Food Consumption and Bowel Symptoms Among Patients With Rectal Cancer After Sphincter-Saving Surgery

Dietary self-management is an important strategy for controlling bowel symptoms after sphincter-saving surgery; however, the dietary factors influencing bowel symptoms are not completely clear. This study aimed to explore the relationship between the specific consumption of food components and bowel symptoms. This study applied a cross-sectional study design. Using convenience sampling, a total of 169 patients with rectal cancer after sphincter-saving surgery were selected from a tertiary hospital. Data were collected through three questionnaires, including general and treatment-related questionnaires, the Memorial Sloan Kettering Cancer Center (MSKCC) bowel function scale-Chinese version, and the Food Frequency Questionnaire. Multiple linear regression analysis was used to analyze the collected data. It was found that the consumption of fruit, cholesterol, and protein and the interaction of cereals and milk products were the main dietary factors affecting bowel symptoms in patients after sphincter-saving surgery. The consumption of protein and fruit was negatively correlated with the symptoms of frequent and urgent defecation, and the consumption of fruit and protein was negatively correlated with general bowel function. The consumption of fruit was negatively correlated with the abnormal feeling of defecation, and the interaction between cereals and milk products was positively correlated with the abnormal feeling of defecation. The results of this study provide evidence for medical staff to further develop scientific dietary education programs to relieve bowel symptoms and promote the quality of life of patients in the future. More research is also needed to explore the mechanisms of the effects of different food components on bowel symptoms in patients after sphincter-saving surgery in the future.

Better Function With a Colonic J-Pouch or a Side-to-end Anastomosis?: A Randomized Controlled Trial to Compare the Complications, Functional Outcome, and Quality of Life in Patients With Low Rectal Cancer After a J-Pouch or a Side-to-end Anastomosis

BACKGROUND INFORMATION

We aimed to compare prospectively the complications and functional outcome of patients undergoing a J-Pouch (JP) or a side-to-end anastomosis (SE) for treatment of low rectal cancer at a 2-year time point after resection for rectal cancer.

METHODS

A multicenter study was conducted on patients with low rectal cancer who were randomized to receive either a JP or SE and were followed for 24 months utilizing SF-12 and FACT-C surveys to evaluate the quality of life (QOL). Fecal incontinence was evaluated using the Fecal Incontinence Severity Index (FISI). Bowel function, complications, and their treatments were recorded.

RESULTS

Two hundred thirty-eight patients (165 males) were randomized with 167 final eligible patients, 80 in the JP group and 87 in the SE group for evaluation. The mean age at surgery was 61 (range 29 to 82) years. The overall mean recurrence rate was 12 of 238, 5% and similar in both groups.

COMPLICATIONS

Overall, 37 of 190 (19%) patients reported complications, 14 of these were Clavien Dindo Grade 3b and 2 were 3a: leak 3 (2 JP,1 SE), fistula 4 (1 JP, 3 SE), small bowel obstruction 4 (3JP, 1 SE), stricture 4 (3 SE, 1 SA), pouch necrosis 2 (JP), and wound infection 5 (2 JP, 3 SE). QOL scores using either instrument between the 2 groups at 12 and 24 months were similar (P > 0.05). Bowel movements, clustering, and FISI scores were similar.

CONCLUSION

At time points of 1 and 2 years after a JP or a SE for low rectal cancer, QOL, functional outcome, and complications are comparable between the groups. Although choosing a particular procedure may depend on surgeon/patient choice or anatomical considerations at the time of surgery, SE functions similar to JP and may be chosen due to the ease of construction.

Dutch validation of the low anterior resection syndrome score

AIM

The aim of this study was to validate the Dutch translation of the low anterior resection syndrome (LARS) score in a population of Dutch rectal cancer patients.

METHOD

Patients who underwent surgery for rectal cancer received the LARS score questionnaire, a single quality of life (QoL) category question and the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire. A subgroup of patients received the LARS score twice to assess the test-retest reliability.

RESULTS

A total of 165 patients were included in the analysis, identified in six Dutch centres. The response rate was 62.0%. The percentage of patients who reported 'major LARS' was 59.4%. There was a high proportion of patients with a perfect or moderate fit between the QoL category question and the LARS score, showing a good convergent validity. The LARS score was able to discriminate between patients with or without neoadjuvant radiotherapy (P = 0.003), between total and partial mesorectal excision (P = 0.008) and between age groups (P = 0.039). There was a statistically significant association between a higher LARS score and an impaired function on the global QoL subscale and the physical, role, emotional and social functioning subscales of the EORTC QLQ-C30 questionnaire. The test-retest reliability of the LARS score was good, with an interclass correlation coefficient of 0.79.

CONCLUSION

The good psychometric properties of the Dutch version of the LARS score are comparable overall to the earlier validations in other countries. Therefore, the Dutch translation can be considered to be a valid tool for assessing LARS in Dutch rectal cancer patients.

The lived experiences of patients with post-operative rectal cancer who suffer from altered bowel function: A phenomenological study

PURPOSE

Altered bowel function is a common consequence of anal sphincter-saving surgery in rectal cancer patients, and bowel symptoms influence patients' daily life and psychosocial status. Patients have inadequate professional support because care specialists fail do fully appreciate the impact of the patients' symptoms. In-depth exploration of the individual's experience is essential to improve the quality of patient care. The purpose of this study was to explore the lived experiences of post-operative rectal cancer patients with altered bowel function.

METHODS

This Husserlian descriptive phenomenological study recruited 16 post-operative rectal cancer patients with altered bowel function. Data was collected through purposive sampling and one-on-one in-depth, semi-structured interviews. Narratives were analyzed thematically using Colaizzi's seven-step method.

RESULTS

Three themes emerged, namely: "living in the restroom", "never backward", and "rebalancing on a new road". "Living in the restroom" described how patients frequent the restroom due to post-operative physical changes. "Never backward" outlined that such changes disturbed their mood, interrupted their daily activities, and affected their family life. "Rebalancing on a new road" described the patients' coping strategies, which included spiritual reconstruction, a new excrement model, an adjusted lifestyle, and peer support.

CONCLUSIONS

Post-operative rectal cancer patients with altered bowel function frequent the restroom for prolonged periods, which disturbs their psychosocial status. However, they are forced to develop coping methods by themselves. Specialists can offer effective early post-operative interventions by thoroughly understanding each patient's symptomatic experience, symptom-related interferences, and primary concerns.

Quality of Life in Rectal Cancer Patients After Chemoradiation: Watch-and-Wait Policy Versus Standard Resection - A Matched-Controlled Study

BACKGROUND

Fifteen to twenty percent of patients with locally advanced rectal cancer have a clinical complete response after chemoradiation therapy. These patients can be offered nonoperative organ-preserving treatment, the so-called watch-and-wait policy. The main goal of this watch-and-wait policy is an anticipated improved quality of life and functional outcome in comparison with a total mesorectal excision, while maintaining a good oncological outcome.

OBJECTIVE

The aim of this study was to compare the quality of life of watch-and-wait patients with a matched-controlled group of patients who underwent chemoradiation and surgery (total mesorectal excision group).

DESIGN

This was a matched controlled study.

SETTINGS

This study was conducted at multiple centers.

PATIENTS

The study population consisted of 2 groups: 41 patients after a watch-and-wait policy and 41 matched patients after chemoradiation and surgery. Patients were matched on sex, age, tumor stage, and tumor height. All patients were disease free at the moment of recruitment after a minimal follow-up of 2 years.

MAIN OUTCOME MEASURES

Quality of life was measured by validated questionnaires covering general quality of life (Short Form 36, European Organization for Research and Treatment of Cancer QLQ-C30), disease-specific total mesorectal excision (European Organization for Research and Treatment of Cancer QLQ-CR38), defecation problems (Vaizey and low anterior resection syndrome scores), sexual problems (International Index of Erectile Function and Female Sexual Function Index), and urinary dysfunction (International Prostate Symptom Score).

RESULTS

The watch-and-wait group showed better physical and cognitive function, better physical and emotional roles, and better global health status compared with the total mesorectal excision group. The watch-and-wait patients showed fewer problems with defecation and sexual and urinary tract function.

LIMITATIONS

This study only focused on watch-and-wait patients who achieved a sustained complete response for 2 years. In addition, this is a study with a limited number of patients and with quality-of-life measurements on nonpredefined and variable intervals after surgery.

CONCLUSIONS

After a successful watch-and-wait approach, the quality of life was better than after chemoradiation and surgery on several domains. However, chemoradiation therapy on its own is not without long-term side effects, because one-third of the watch-and-wait patients experienced major low anterior resection syndrome symptoms, compared with 66.7% of the patients in the total mesorectal excision group.

Anorectal complications after robotic intersphincteric resection for low rectal cancer

BACKGROUND

Robotic intersphincteric resection (ISR) has been introduced for sphincter-preservation in the treatment of low rectal cancer. However, many patients experience anorectal symptoms and defecatory dysfunction after ISR. This study aims to evaluate the anorectal complications that develop after ISR.

METHODS

The medical records of 108 patients who underwent robotic ISR at Taipei Medical University Hospital, Taipei, Taiwan between December 2011 and June 2016 were retrospectively reviewed. Photographic records of perineal conditions were documented at the following time intervals after surgery: 1 day, 2 weeks, 1, 2, 3 and 6 months. Clinical outcomes and treatment results were analysed.

RESULTS

Eighty-five patients (78.7%) developed edematous hemorrhoids after surgery. These subsided at a median of 56 days after operation (range 23-89 days). Forty-six patients (42.6%) were found to have anal stenosis requiring anal dilatation. Sixteen patients (14.8%) had neorectal mucosal prolapse, which was noted to occur at an average of 98 days after surgery (range 41-162 days). Multivariate analysis showed that the occurrence of edematous hemorrhoids was associated with operating time (P = 0.043), and male gender was a significant risk factor for anal stenosis (P = 0.007).

CONCLUSIONS

This is the first study reporting on the clinical outcomes of anorectal status after robotic ISR. Further studies are needed to assess the long-term effects of these anorectal complications.

Anorectal functional outcome following laparoscopic low anterior resection for rectal cancer

Low anterior resection (LAR) with total mesorectal excision has been considered a standard treatment for patients with rectal cancer. However, the functional outcome and life quality of laparoscopic LAR (LLAR) in Chinese patients remain unclear. A cohort of 51 Chinese patients (22 men and 29 women) who had undergone LLAR was included in this study. Anorectal manometry combined with the Wexner scores questionnaire were applied to assess functional outcome preoperatively (1 week) and postoperatively (at 3, 6 and 9 months). The validated Chinese versions of the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-CR38 questionnaires were also used to assess the patients' quality of life at the indicated time points. The results demonstrated that the manometric parameters exhibited a temporary decrease at 3 months postoperatively, but a gradual increase at 6 and 9 months, while the Wexner scores exhibited an opposite trend. Furthermore, patients with high anastomoses had significantly higher manometric parameters, a lower frequency of incontinence and lower Wexner scores compared with those with low anastomoses at 9 months (all P<0.05). For the entire cohort, quality of life at 3 months postoperatively was worse compared with the preoperative level, but returned to normal by 9 months. Patients with high anastomoses exhibited significantly better role, emotional and social function, had a better body image and sexual function, fewer problems with defecation and lower frequency of diarrhea, as well as fewer chemotherapy-related side effects at 6 months postoperatively when compared with the low anastomosis group (all P<0.05). In conclusion, LLAR is generally acceptable for Chinese patients with rectal cancer, particularly for those with middle or high rectal cancer, in terms of functional outcome and quality of life.

Conversations for providers caring for patients with rectal cancer: Comparison of long-term patient-centered outcomes for patients with low rectal cancer facing ostomy or sphincter-sparing surgery

For some patients with low rectal cancer, ostomy (with elimination into a pouch) may be the only realistic surgical option. However, some patients have a choice between ostomy and sphincter-sparing surgery. Sphincter-sparing surgery has been preferred over ostomy because it offers preservation of normal bowel function. However, this surgery can cause incontinence and bowel dysfunction. Increasingly, it has become evident that certain patients who are eligible for sphincter-sparing surgery may not be well served by the surgery, and construction of an ostomy may be better. No validated assessment tool or decision aid has been published to help newly diagnosed patients decide between the two surgeries or to help physicians elicit long-term surgical outcomes. Furthermore, comparison of long-term outcomes and late effects after the two surgeries has not been synthesized. Therefore, this systematic review summarizes controlled studies that compared long-term survivorship outcomes between these two surgical groups. The goals are: 1) to improve understanding and shared decision-making among surgeons, oncologists, primary care providers, patients, and caregivers; 2) to increase the patient's participation in the decision; 3) to alert the primary care provider to patient challenges that could be addressed by provider attention and intervention; and 4) ultimately, to improve patients' long-term quality of life. This report includes discussion points for health care providers to use with their patients during initial discussions of ostomy and sphincter-sparing surgery as well as questions to ask during follow-up examinations to ascertain any long-term challenges facing the patient.

Pelvic floor muscle exercise for fecal incontinence quality of life after coloanal anastomosis

AIMS AND OBJECTIVES

To assess the efficacy of pelvic floor muscle exercise for enhancing fecal incontinence quality of life after coloanal anastomosis in colorectal cancer patients.

BACKGROUND

Methods of improving incontinence have been evaluated in many countries, but never in a Taiwan population.

DESIGN

A longitudinal experimental study.

METHODS

Fifty-two colorectal cancer patients who had received colostomy closure and coloanal anastomosis surgery were recruited from a general hospital in southern Taiwan and randomly assigned to an experimental group (n = 26) or a control group (n = 26). Both groups received routine postoperative care. However, the experimental group received private consultations, educational DVDs and pamphlets to instruct them in performing pelvic flow muscle exercise. In all participants, the Fecal Incontinence Quality of Life Scale was used to measure quality of life before discharge and at one, two, three, six and nine months after discharge. Generalised estimating equations were used to compare longitudinal effects between the two groups.

RESULTS

The generalised estimating equations revealed that all participants had significantly improved Fecal Incontinence Quality of Life Scale scores at two, three, six and nine months after discharge. Compared to the controls, however, the experimental group had significantly higher scores at two, three, and six months after discharge.

CONCLUSIONS

Patient education in pelvic floor muscle exercise positively affects Fecal Incontinence Quality of Life Scale scores in patients who have received coloanal anastomosis.

RELEVANCE TO CLINICAL PRACTICE

Early education in pelvic floor muscle exercise can improve management of fecal incontinence symptoms after coloanal anastomosis and can improve quality of life.

Satisfaction With Life And Disease Acceptance By Patients With A Stomy Related To Surgical Treatment Of The Rectal Cancer--Determinants Of Quality Of Life?

Satisfaction with life and disease acceptance by patients with a stomy related to surgical treatment of the rectal cancer depend on multiple factors. Such factors as social support, life conditions and time that elapsed after stomy creation, are very important in this context. The aim of the study was to conduct an early evaluation of life satisfaction and disease acceptance by patients with a stomy related to surgical treatment of the rectal cancer.

MATERIAL AND METHODS

The study was conducted at Dr. Jan Biziel University Hospital No. 2 in Bydgoszcz and at the prof. F. Łukaszczyk Oncology Centre in Bydgoszcz in 2014. The final analysis included 96 subjects aged 41-87 years (median 59 years). Satisfaction With Life Scale (SWLS) and Acceptance of Illness Scale (AIS) adapted by Zygfryd Juczyński, were used in this study.

RESULTS

Most patients had satisfaction with life score of 5 or 6, 23 (24%) and 28 (29.2%) subjects, respectively. Twenty nine (30.2%) study subjects had low satisfaction level, while 16 (16.7%) had high satisfaction level. Average disease acceptance score was 23.2 points. Most patients, 71 (74%) had a moderate disease acceptance score, while the lowest number of subjects, 9 (9.4%), had high disease acceptance score. None of the study subjects who were under the care of a psychologist (14/100%) did not have a low acceptance level.

CONCLUSIONS

Half of the study subjects had a moderate level of satisfaction with life. Most patients with stomy related to surgical treatment of the rectal cancer in an early postoperative period had moderate level of the disease acceptance. Patients with high level of satisfaction with life, accept the disease better. Few patients who used help by a psychologist, were two- and three-fold more likely to have higher level of satisfaction with life and disease acceptance, respectively.
