Unexpected internal hernia in a patient with small bowel obstruction: an old surgical axiom.

BMJ Case Rep 2021 May 6;14(5). Epub 2021 May 6.

Department of General Surgery, Ayr Hospital, Ayr, UK.

An 85-year-old man with no previous laparotomies and no herniae presented with a small bowel obstruction. CT imaging did not suggest any obvious cause; however, a transition point at the terminal ileum was noted. At laparotomy, the small bowel was unexpectedly found to be obstructed through a tight anterior hiatal defect. No resection was required and the defect was closed. On retrospective review of the CT images, the herniated small bowel can clearly be seen anterior to the oesophagus and can also be appreciated as a retrocardiac air-fluid level on chest X-ray (initially felt to be a small type I hiatal hernia). Our case highlights the surgical axiom that in patients with small bowel obstruction with no scars and no herniae consideration should be given to an unusual or sinister cause.

Lifestyle interventions are feasible in patients with colorectal cancer with potential short-term health benefits: a systematic review.

Int J Colorectal Dis 2017 Jun 3;32(6):765-775. Epub 2017 Apr 3.

Centre for Public Health Nutrition Research, Division of Cancer Research, Ninewells Medical School, Level 7, Mailbox 7, Dundee, DD1 9SY, UK.

Purpose: Lifestyle interventions have been proposed to improve cancer survivorship in patients with colorectal cancer (CRC), but with treatment pathways becoming increasingly multi-modal and prolonged, opportunities for interventions may be limited. This systematic review assessed the evidence for the feasibility of performing lifestyle interventions in CRC patients and evaluated any short- and long-term health benefits.

Methods: Using PRISMA Guidelines, selected keywords identified randomised controlled studies (RCTs) of lifestyle interventions [smoking, alcohol, physical activity (PA) and diet/excess body weight] in CRC patients. These electronic databases were searched in June 2015: Dynamed, Cochrane Database, OVID MEDLINE, OVID EMBASE, and PEDro.

Results: Fourteen RCTs were identified: PA RCTs (n = 10) consisted mainly of telephone-prompted walking or cycling interventions of varied durations, predominately in adjuvant setting; dietary/excess weight interventions RCTs (n = 4) focused on low-fat and/or high-fibre diets within a multi-modal lifestyle intervention. There were no reported RCTs in smoking or alcohol cessation/reduction. PA and/or dietary/excess weight interventions reported variable recruitment rates, but good adherence and retention/follow-up rates, leading to short-term improvements in dietary quality, physical, psychological and quality-of-life parameters. Only one study assessed long-term follow-up, finding significantly improved cancer-specific survival after dietary intervention.

Conclusions: This is the first systematic review on lifestyle interventions in patients with CRC finding these interventions to be feasible with improvements in short-term health. Future work should focus on defining the optimal type of intervention (type, duration, timing and intensity) that not only leads to improved short-term outcomes but also assesses long-term survival.

Analysis of lesion localisation at colonoscopy: outcomes from a multi-centre U.K. study.

Surg Endosc 2017 07 8;31(7):2959-2967. Epub 2016 Nov 8.

Department of Surgery, Royal Alexandra Hospital, Corsebar Road, Paisley, PA2 9PN, Scotland, UK.

Background: Colonoscopy is currently the gold standard for detection of colorectal lesions, but may be limited in anatomically localising lesions. This audit aimed to determine the accuracy of colonoscopy lesion localisation, any subsequent changes in surgical management and any potentially influencing factors.

Methods: Patients undergoing colonoscopy prior to elective curative surgery for colorectal lesion/s were included from 8 registered U.K. sites (2012-2014). Three sets of data were recorded: patient factors (age, sex, BMI, screener vs. symptomatic, previous abdominal surgery); colonoscopy factors (caecal intubation, scope guide used, colonoscopist accreditation) and imaging modality. Lesion localisation was standardised with intra-operative location taken as the gold standard. Changes to surgical management were recorded.

Results: 364 cases were included; majority of lesions were colonic, solitary, malignant and in symptomatic referrals. 82% patients had their lesion/s correctly located at colonoscopy. Pre-operative CT visualised lesion/s in only 73% of cases with a reduction in screening patients (64 vs. 77%; p = 0.008). 5.2% incorrectly located cases at colonoscopy underwent altered surgical management, including conversion to open. Univariate analysis found colonoscopy accreditation, scope guide use, incomplete colonoscopy and previous abdominal surgery significantly influenced lesion localisation. On multi-variate analysis, caecal intubation and scope guide use remained significant (HR 0.35, 0.20-0.60 95% CI and 0.47; 0.25-0.88, respectively).

Conclusion: Lesion localisation at colonoscopy is incorrect in 18% of cases leading to potentially significant surgical management alterations. As part of accreditation, colonoscopists need lesion localisation training and awareness of when inaccuracies can occur.

Improving lesion localisation at colonoscopy: an analysis of influencing factors.

Int J Colorectal Dis 2015 Jan 7;30(1):111-8. Epub 2014 Nov 7.

School of Medicine, University of Glasgow, Glasgow, G12 8QQ, UK.

Purpose: Colonoscopy detects colorectal cancer and determines lesion localisation that influences surgical planning. However, published work suggests that the accuracy of lesion localisation can be low as 60%, with implications for both the surgeon and the patient. This work aims to identify potential influencing factors at colonoscopy that could lead to improved lesion localisation accuracy.

Methods: A multi-centred, prospective, observational study was performed that identified patients who were undergoing planned curative resection for a colorectal lesion. Localisation of a lesion at colonoscopy was compared to the intra-operative lesion localisation to determine accuracy of colonoscopic localisation. Patient factors and colonoscopic factors were recorded to determine any influencing factors on lesion localisation at colonoscopy.

Results: One hundred and eleven patients were analysed: mean age 67.4 years (range 27-89); male:female ratio 1.3:1; symptomatic referrals (n = 78, 70.3%); and previous abdominal surgery in 27 patients (24.3%). Complete colonoscopy was recorded in 78 patients (70.3%). In 88 patients (79.3%), colonoscopic lesion localisation matched the intra-operative location. Pre-operative CT imaging was unable to identify the tumour in 24 cases (21.8%). Potential influencing patient and colonoscopic factors on accurate lesion localisation at colonoscopy found complete colonoscopy to be the only significant factor (p = 0.008).

Conclusion: Colonoscopic lesion localisation was found to be inaccurate in 79.3% cases, and with pre-operative CT unable to detect all lesions, this study confirms that accurate lesion localisation in the modern era is increasingly reliant on colonoscopy. Incomplete colonoscopy was the only significant factor that influenced inaccurate lesion localisation at colonoscopy.
