The Role of Traditional Acupuncture in Low Anterior Resection Syndrome Treatment: A Pilot Study

Systematic review of the management options available for low anterior resection syndrome (LARS)

BACKGROUND

Rectal cancer incidence is increasing. Low anterior resection is currently the gold standard surgical management. Postoperatively, patients may present with symptoms indicative of low anterior resection syndrome (LARS). LARS can be debilitating and is difficult to treat with low efficacy of treatment modalities. This systematic review aims to highlight the current evidence regarding LARS management.

METHODS

Systematic review of Medline, Cochrane and Embase used the following terms: "low anterior resection syndrome" AND "management", "low anterior resection syndrome" AND "treatment". Articles that focus solely of low anterior resection syndrome management in patients > 18 years were included. Bias risk was assessed via the Newcastle-Ottawa quality assessment scale for cohort studies and the JBI critical appraisal tool for randomized controlled trials. Due to heterogeneity of methodology, no statistical analysis was performed.

RESULTS

Thirty-eight articles with a total of 1914 patients were included in this review. Ninety-five per cent underwent surgery for malignancy. Treatment options included pharmacology, pelvic floor rehabilitation (PFR), transanal irrigation (TAI), sacral nerve modulation (SNM), percutaneous tibial nerve stimulation (PTNS) and "treatment programs" starting from the least invasive procedures escalating to more invasive treatments upon failure. The most common published medical therapies report Ramoestron use; however, studies are low impact. PFR showed significant improvement in LARS mostly in those with symptoms of faecal incontinence. However, long-term outcomes are inconsistent. TAI supplies pseudo-continence with its greatest benefit reported in those with incomplete evacuation. TAI has significant short-term effects on LARS but little long-term effect. TAI is also associated with a significant drop-out rate. SNM's hypothesised benefit is extrapolated from non-LARS associated FI. Results show improvements in FI but a high rate of explantation. PTNS evidence suggests little if any significant LARS improvement. A single "stepwise programme" study reported that 77 per cent did not progress further than diet and medication. Little evidence suggests benefit regarding diet or acupuncture.

DISCUSSION

There is no consensus as to the optimal treatment strategy for LARS. LARS is multifactorial and requires sensitive discussion between patient and surgeon to address the most prominent symptom. It requires physical and psychological input. No single treatment option provides superior results. Treatment is based on symptom control and patient acceptance.

A comparative study of acupuncture combined with rehabilitation gymnastics on postoperative anal function of lower rectal cancer

BACKGROUND

From the anal function, inflammatory response and other indicators, acupuncture combined with rehabilitation gymnastics was applied to patients with cancer undergoing low resection, aiming to improve the prognosis of patients.

AIM

To explore the effects of acupuncture combined with rehabilitation gymnastics on anal function after lower rectal cancer surgery.

METHODS

From January 2020 to December 2022, 128 patients who underwent rectal cancer surgery in the Department of Oncology of Hebei Provincial Hospital of Traditional Chinese Medicine Hospital were selected and divided into two groups using the random number table method, with 64 patients in each group. Patients in the control group were not treated with acupuncture or rehabilitation gymnastics and served as blank controls. Patients in the study group were treated with acupuncture and rehabilitation gymnastics from the 7th postoperative day. The anal incontinence scores, changes in serum interleukin-4, interleukin-6, and interleukin-10 Levels, and serum motilin, 5-hydroxytryptamine, and vasoactive intestinal peptide levels were compared.

RESULTS

There were no significant differences in serum interleukin-4, interleukin-6, and interleukin-10 Levels between the groups before treatment (P > 0.05). After treatment, these levels were better than those of the control group (P < 0.05). There was no significant difference in the anal incontinence scores between the groups before and 7 d after surgery (P > 0.05). Anal incontinence scores in the study group were lower than those in the control group at 14 d, 21 d, and 28 d postoperatively (P < 0.05). There were no significant differences in serum motilin, 5-hydroxytryptamine, or vasoactive intestinal peptide levels between the groups before treatment (P > 0.05). After treatment, these levels were higher in the study group than in the control group, and vasoactive intestinal peptide level was lower in the study group than in the control group (P < 0.05).

CONCLUSION

Acupuncture combined with rehabilitation gymnastics can promote the recovery of anal function and reduce the inflammatory response in patients with lower rectal cancer after surgery.

The Effect of comprehensive rehabilitation on Lithuanian adolescent's nonspecific low back pain, depending on the duration: Nonrandomized single-arm trial

OBJECTIVE

To determine pain and functional changes during comprehensive rehabilitation (CR) in adolescents with nonspecific low back pain (NLBP), and to determine the optimal CR duration.

METHODS

The study included 106 adolescents (39 boys [36.8%], 67 girls [63.2%]), 14 to17 years old, with the following inclusion criteria: duration of NLBP for at least 12 weeks; conservative NLBP treatment was effectless; pain intensity using the visual analogue pain scale (VAS) ≤ 7 points; disrupted daily activities; ability to understand and answer the questions; written consent to participate voluntarily in the study. The pain was assessed using the VAS scale, functional changes were assessed using the Oswestry Disability Index (ODI), 12-Item Short Form Survey, Hospital Anxiety and Depression Scale (HAD), and physical functional capacity and proprioception (Proprio) were assessed using an isokinetic dynamometer. The participants performed a comprehensive pain rehabilitation program consisting of physiotherapy, TENS, magnetotherapy, lumbar massage, and relaxing vibroacoustic therapy. The active CR cycle lasted for 22 sessions (with intermediate measurements after 5 and 16 sessions), after which we performed passive observation for another half a year. Five measurements were performed.

RESULTS

Pain, functional assessment, and physical capacity were improved with CR. Statistically significant improvement became apparent after 5 CR sessions, but statistical and clinical significance became apparent after 16 CR sessions. In the distant period, after the completion of CR, neither statistical nor clinical changes occurred.

CONCLUSIONS

CR is effective in reducing pain, and improving functional state and physical capacity quickly and reliably in 16 CR sessions, which is sufficient to obtain clinically satisfactory CR results. Good results were achieved during CR and neither improved nor deteriorated spontaneously in the distant period. This study shows a possible mismatch between NLBP intensity and impaired functional state in adolescents.
