ABSTRACT

PURPOSE: Invasive surgical management of cryptoglandular perianal fistulas (PF) is challenging because of high recurrence rates and the potential for injury to the sphincter complex. In the present technical note, we introduce a minimally invasive treatment for PF using a perianal fistula implant (PAFI) comprising ovine forestomach matrix (OFM). METHODS: This retrospective observational case series highlights 14 patients who had undergone a PAFI procedure at a single center between 2020 and 2023. During the procedure, previously deployed setons were removed and tracts were de-epithelialized with curettage. OFM was rehydrated, rolled, passed through the debrided tract, and secured in place at both openings with absorbable suture. Primary outcome was fistula healing at 8 weeks, and secondary outcomes included recurrence or postoperative adverse events. RESULTS: Fourteen patients underwent PAFI using OFM with a mean follow-up period of 37.6 ± 20.1 weeks. In follow-up, 64% (n = 9/14) had complete healing at 8 weeks and all remained healed, except one at last follow-up visit. Two patients underwent a second PAFI procedure and were healed with no recurrence at the last follow-up visit. Of all patients that healed during the study period (n = 11), the median time to healing was 3.6 (IQR 2.9-6.0) weeks. No postprocedural infections nor adverse events were noted. CONCLUSIONS: The minimally invasive OFM-based PAFI technique for PF treatment was demonstrated to be a safe and feasible option for patients with trans-sphincteric PF of cryptoglandular origin.

ABSTRACT

Bifidobacterium infantis NLS super strain (B. infantis NLS-SS) was previously shown to alleviate gastrointestinal symptoms in newly diagnosed coeliac disease (CD) patients consuming gluten. A high proportion of patients following a gluten-free diet experiences symptoms despite dietary compliance. The role of B. infantis in persistently symptomatic CD patients has not been explored. The aim of the study was to evaluate the effect of B. infantis NLS-SS on persistent gastrointestinal symptoms in patients with CD following a long-term GFD. We conducted a randomised, cross-over, double-blind, placebo-controlled trial in symptomatic adult CD patients on a GFD for at least two years. After one-week run-in, patients were randomised to B. infantis NLS-SS or placebo for 3 weeks with cross-over after a 2-week wash-out period. We estimated changes (Δ) in celiac symptom index (CSI) before and after treatment. Stool samples were collected for faecal microbiota analysis (16S rRNA sequencing). Gluten immunogenic peptide (GIP) excretion in stool and urine samples was measured at each study period. Eighteen patients were enrolled; six patients were excluded due violations in protocol. For patients with the highest clinical burden, CD symptoms were lower in probiotic than in placebo treatment (P=0.046). B. infantis and placebo treated groups had different microbiota profiles as assessed by beta diversity clustering. In probiotic treated groups, we observed an increase in abundance of B. infantis. Treatment with B. infantis was associated with decreased abundance of Ruminococcus sp. and Bifidobacterium adolescentis. GIP excretion in stools and urine was similar at each treatment period. There were no differences in adverse effects between the two groups. B. infantis NLS-SS improves specific CD symptoms in a subset of highly symptomatic treated patients (GFD). This is associated with a shift in stool microbiota profile. Larger studies are needed to confirm these findings. ClinicalTrials.gov: NCT03271138.

ABSTRACT

BACKGROUND: Both frailty and older age are risk factors for adverse surgical outcomes. We hypothesized that frailty, regardless of patient age, is a predictor of poor postoperative outcome among patients with rectal cancer undergoing proctectomy. METHODS: Patients with primary rectal cancer undergoing proctectomy between 2012 to 2015 were identified in the database of the National Quality Improvement Program. The simplified, 5-item frailty index was grouped into 0, 1, 2, and ≥3. Outcomes were morbidity and 30-day mortality. RESULTS: This study involved 9,252 patients from the National Quality Improvement Program database. Increasingly frail patients had greater morbidity and mortality (P < .001). Logistic regression revealed that frailty was a predictor of morbidity (odds ratio = 6.7, P < .0001); in contrast, older age was not associated with morbidity when adjusting for frailty (odds ratio = 1.2, P = .14). Both older age and frailty were associated with greater mortality, with frailty (odds ratio = 20.8, P < .0001) more so than older age (odds ratio = 10.3, P < .0001). CONCLUSION: Frailty was more strongly associated with morbidity and mortality than older age in patients undergoing proctectomy. Surgical options can be expanded to older patients with the use of simplified, 5-item frailty index as a decision-making tool.

ABSTRACT

CONTEXT: Stroke is a leading cause of death and disability worldwide, being the third leading cause of death in the United States and the second and third most common causes of death in Chinese cities and rural areas, respectively. Evaluation of different rehabilitative modalities appears necessary to optimize treatment. OBJECTIVES: To compare acupuncture and physiotherapy for effectiveness and reliability in treating hemiplegic patients after stroke. DESIGN: The research team designed a multicentered, three-arm, randomized controlled trial. Power calculations revealed a targeted sample size of 310 participants. SETTING: The study took place at seven in-patient hospitals in China. PARTICIPANTS: The research team screened a total of 310 patients. Of that number, 274 completed the study, 15 did not meet the inclusion/exclusion criteria, and 21 dropped out. Adverse events were rare (less than 1%), mild, and temporary. INTERVENTION: The research team randomly divided participants into three groups that all received conventional care as needed-including psychological counseling, standard nursing care, and daily medical evaluation plus (1) acupuncture, (2) physiotherapy, or (3) acupuncture plus physiotherapy. The participants received treatments once a day, 6 days a week for 4 weeks. OUTCOME MEASURES: The research team evaluated all patients at baseline, after 2 weeks, and after 4 weeks using the Fugl-Meyer Assessment of Physical Performance (FMA), a modified Barthel Index (BI), and the Neurologic Defect Scale (NDS). RESULTS: No significant differences existed between the three groups at baseline. Compared to baseline, participants in all groups improved their FMA, BI, and NDS scores by the end of week 2 (P≤.05) and further improved by the end of week 4 (P≤.05) The study found no statistically significant differences in outcomes between the three groups after treatment (P>.05). CONCLUSION: Acupuncture plus conventional care was similar in effectiveness to physiotherapy treatment plus conventional care for poststroke rehabilitation. The study found no synergistic effects for the combination of acupuncture and physiotherapy in addition to conventional care; that combination of treatments was no more effective than either treatment by itself. The effectiveness and lack of adverse events associated with acupuncture in this study suggest that it may represent an additional treatment option for stroke patients.
