The benefits of index telephone consultations in patients referred on the two-week wait colorectal cancer pathway.

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic led to hospitals in the UK substituting face-to-face (FtF) clinics with virtual clinic (VC) appointments. We evaluated the use of virtual two-week wait (2-ww) lower gastrointestinal (LGI) clinic appointments, conducted using telephone calls at a district general hospital in England. METHODS: Patients undergoing index outpatient 2-ww LGI clinic assessment between 1 June 2019 and 31 October 2019 (FtF group) and 1 June 2020 and 31 October 2020 (VC group) were identified. Relevant data were obtained using electronic patient records. Compliance with national cancer waiting time targets was assessed. Environmental and financial impact analyses were performed. RESULTS: In total, 1,531 patients were analysed (median age=70, male=852, 55.6%). Of these, 757 (49.4%) were assessed virtually via telephone; the remainder were seen FtF (n=774, 50.6%). Ninety-two (6%, VC=44, FtF=48) patients had malignant pathology and 64 (4.2%) had colorectal cancer (CRC); of these, 46 (71.9%, VC=26, FtF=20) underwent treatment with curative intent. The median waiting times to index appointment, investigation and diagnosis were significantly lower following VC assessment (p<0.001). The cancer detection rates (p=0.749), treatments received (p=0.785) and median time to index treatment for CRC patients (p=0.156) were similar. A significantly higher proportion of patients were seen within two weeks of referral in the VC group (p<0.001). VC appointments saved patients a total of 9,288 miles, 0.7 metric tonnes of CO2 emissions and £7,482.97. Taxpayers saved £80,242.00 from VCs. No formal complaints were received from patients or staff in the VC group. CONCLUSION: Virtual 2-ww LGI clinics were effective, safe and were associated with tangible environmental and financial benefits.

Challenges and improvement needs in the care of patients with central diabetes insipidus.

Central diabetes insipidus (CDI) is a rare condition, with significant impact on patient health and well-being. It is a chronic condition which usually requires meticulous long-term care. It can affect both children and adults. There is limited literature considering the needs and challenges inherent in providing high quality care to patients with CDI, across the care pathway. This paper seeks to address this gap by providing a unique and well-rounded understanding of clinical and healthcare systems-related challenges. It draws on insights from the literature, from direct clinical experience contributed by five clinicians as co-authors (providing insights from France, Ireland, Italy, Spain and the United Kingdom), and from patient perspectives provided through interviews with patient representatives from three patient organisations. We identify clinical challenges related to the diagnosis of CDI, including differentiating between other similar conditions and determining the underlying aetiology. Treatment is challenging, given the need to tailor medication to each patient's needs and ongoing management is required to ensure that patients continue to respond adequately to treatment. Ongoing support is required when patients switch between formulations. We also identify healthcare systems challenges related to limited awareness of CDI amongst primary care physicians and general paediatricians, and the need for highly skilled specialist care and appropriate workforce capacity. There is also a significant need for raising awareness and for the education of both healthcare professionals and patients about different aspects of CDI, with the aim of supporting improved care and effective patient engagement with healthcare professionals. We reflect on this information and highlight improvement opportunities. These relate to developing guidance to support patients, carers, primary care physicians and general paediatricians to identify clinical features earlier, and to consider CDI as a possible diagnosis when a patient presents with suggestive symptoms.

Is it time for one-step nucleic acid amplification (OSNA) in colorectal cancer? A systematic review and meta-analysis.

BACKGROUND: Lymph node metastasis (LNM) is prognostic in colorectal cancer (CRC). However, evaluation by routine haematoxylin and eosin histology (HE) limits nodal examination and is subjective. Missed LNMs from tissue allocation bias (TAB) might under-stage disease, leading to under-treatment. One-step nucleic acid amplification (OSNA) for CK19 messenger ribonucleic acid (mRNA), a marker of LNM, analyses the whole node. The aim of the present systematic review and meta-analysis was to assess recent studies on OSNA versus HE and its implications for CRC staging and treatment. METHODS: Databases including OVID, Medline and Google Scholar were searched for OSNA, LNM and CRC. Study results were pooled using a random-effects model. Summary receiver operator curves (SROC) assessed OSNA's performance in detecting LNM when compared to routine HE histology. RESULTS: Five case-control studies analysing 4080 nodes from 622 patients were included. The summary estimates of pooled results for OSNA were sensitivity 0.90 [95% confidence interval (CI) 0.86-0.93], specificity 0.94 (95% CI 0.93-0.95) and diagnostic odds ratio 179.5 (CI 58.35-552.2, p < 0.0001). The SROC curve indicated a maximum joint sensitivity and specificity of 0.88 and area under the curve of 0.94, p < 0.0001. On average, 5.4% HE-negative nodes were upstaged by OSNA. CONCLUSIONS: OSNA is as good as routine HE. It may avoid TAB and offer a more objective and standardised assay of LNM. However, for upstaging, its usefulness as an adjunct to HE or superiority to HE requires further assessment of the benefits, if any, of adjuvant therapy in patients upstaged by OSNA.

Metastasis-induced pancreatitis: case report.

This report aims to highlight the importance of malignancy exclusion in the absence of common aetiology in acute pancreatitis. An 83-year-old woman presented acutely with pancreatitis. There had been no history suggestive of gallstones disease and she rarely consumed alcohol. Subsequent ultrasound scan revealed no gallstones but multiple liver metastatic lesions. Further carcinomatosis involving the pancreas, right ovary, pelvic lymphatics and nodular disease of the lungs was demonstrated on computed tomography. Immuno-histochemistry of liver biopsy showed positivity for markers suggestive of metastasis arising from lung small cell carcinoma. The case was discussed at the lung multidisciplinary meeting and the patient was referred for community palliative care. Early diagnosis of metastasis induced pancreatitis allows immediate institution of palliative care, if not suitable for aggressive pharmaco-surgical intervention.

Spontaneously ruptured splenic aneurysm in a young patient with Ehlers-Danlos syndrome.

The authors describe a young patient with a history of type IV vascular Ehlers-Danlos syndrome (EDS) who underwent successful treatment for a spontaneous haemorrhage from a splenic artery aneurysm, and the authors would like to remind clinicians of the mortality and morbidity associated with vascular-type EDS.

Management of obstetric anal sphincter injuries--a role for the colorectal surgeon.

AIM: To determine if surgical repair of third and fourth degree obstetric perineal tears by an experienced colorectal surgeon produces satisfactory functional results in the short and long term. METHOD: Consecutive deliveries were studied prospectively over a 32-month period. All patients with suspected third or fourth degree tears were referred to the colorectal team. Following confirmation of the injury, patients underwent surgical repair using a standard overlapped technique according to an established protocol. The patients were reviewed 2 months later. Long-term continence was determined, by postal and telephone follow up, after a minimum of 3 years. RESULTS: Fifty-nine sphincter injuries were identified and repaired by the colorectal team. Two months following repair 51 (86%) of patients had normal continence, four (7%) had urgency, and five (8%) had occasional incontinence of flatus. All patients with any degree of incontinence underwent endoanal ultrasound at which no sphincter defects were noted, and all improved symptomatically following pelvic floor physiotherapy. Long-term follow up data was obtained in 45 women. Thirty-nine (87%) had normal continence scores, 11 (24%) described urgency, but only three (7%) were often incontinent of liquid stool. Seven (15%) were occasionally incontinent of flatus. CONCLUSION: Excellent short and long-term functional results were obtained in the repair of third and fourth degree tears when performed by experienced colorectal surgeons. Since the protocol was established, obstetricians in North Cheshire have adopted the double overlapped technique, and now manage the majority of these injuries themselves.

The aetiology and epidemiology of faecal incontinence.

Faecal incontinence is experienced by at least 2% of the population and 7% of those over 65 years of age. The true incidence is probably much higher because of the stigmata of the affliction leading to underreporting. The common causes of faecal incontinence are discussed.

The surgical management of faecal incontinence.

The surgical management of faecal incontinence is complex and technically demanding. Surgery should only be offered once the aetiology has been correctly identified and the patient has been counselled regarding outcomes of success. This may only approach 80%, with long-term results declining with time.

Recent developments in the treatment of faecal incontinence.

Many patients with faecal incontinence can be cured using a simple anal sphincter repair. Some patients are unsuitable for this either because the sphincter is absent, too extensively damaged or anal sphincter repair has failed. In these patients novel treatments have been introduced to augment, replace and stimulate the anal sphincter.

Panniculitis, arthritis and pancreatitis.

Subcutaneous fat necrosis is seen in 2% of patients with pancreatic disorders and may predate clinical symptoms by up to 3 weeks. Furthermore, 2% of cases of acute pancreatitis are clinically silent. Therefore, the differential diagnosis is extensive and the definitive diagnosis is evasive. The treatment of prolonged hyperamylasaemia and hyperlipasaemia is challenging and still experimental. Further studies are required to introduce effective treatment protocols.
