The straight to test endoscopy service for suspected colorectal cancer: meeting national targets but are we meeting our patients' expectations?

AIM: The NHS Cancer Plan describes initiatives to improve patient care in the UK, including the two-week rule cancer referral pathway. To meet this target a straight to test (STT) endoscopy service was devised to expedite diagnosis of suspected colorectal cancer. Our novel study aimed to determine patient satisfaction with this new approach to rapid access investigation. METHOD: An anonymized questionnaire was posted to 300 patients who had undergone STT endoscopy in our unit between January and June 2010. It assessed satisfaction with the service overall, time from referral to investigation, pre-test information, bowel preparation instructions and time to results as well as preference for a traditional pre-test or post-test outpatient appointment and awareness that the referral was for suspected bowel cancer. RESULTS: In all, 174 questionnaires were obtained (58% yield; mean age 68.8; 44.8% men). 82.2% of patients were 'very satisfied' with the service overall, 82.8% with time from referral to test, 75.2% with time from test to results, 73% with endoscopy information and 69.5% with bowel preparation instructions. Eight per cent would rather have seen a specialist prior to endoscopy, 31.6% would have preferred a post-test appointment and 68.4% of patients were aware that referral was for suspected bowel cancer. CONCLUSION: Straight to test is popular with patients. It offers a fast and cost effective service in the diagnosis of colorectal cancer and meets national targets whilst reducing the volume burden on outpatient clinics. However, its success heavily relies on accurate communication between general practitioner, patient and secondary care.

A systematic review comparing transanal haemorrhoidal de-arterialisation to stapled haemorrhoidopexy in the management of haemorrhoidal disease.

BACKGROUND: The aim of this study was to systematically analyse the clinical trials on the effectiveness of transanal haemorrhoidal de-arterialisation (THD) and stapled haemorrhoidopexy (SH) in the management of haemorrhoidal disease (HD). METHODS: Clinical trials on the effectiveness of THD and SH in the management of HD were analysed systematically using RevMan(®), and combined outcomes were expressed as risk ratio (RR) and mean difference (MD). RESULTS: Three randomised, controlled trials encompassing 150 patients were analysed systematically. There were 80 THD patients and 70 SH patients. There was no significant heterogeneity (P = 0.40) among included trials. Therefore, in the fixed effects model, THD and SH were statistically equivalent in terms of treatment success rate (P = 0.19), operation time (P = 0.55), postoperative complications (P = 0.11) and recurrence (P = 0.46) of HD. THD was associated with significantly less postoperative pain (MD, -2.00; 95% CI, -2.06, -1.94; z = 63.59; P < 0.00001) compared to SH. CONCLUSIONS: Both THD and SH are equally effective and can be attempted for the management of HD. However, THD is associated with significantly lesser postoperative pain and therefore may be considered a preferred procedure. This conclusion is based only on treating 150 patients by THD or SH in three moderate-quality randomised trials. A major, multicenter, randomised trial is required to validate this conclusion and investigate other variables like hospital stay, cost-effectiveness and health-related quality of life measurement.

Validation of the size morphology site access score in endoscopic mucosal resection of large polyps in a district general hospital.

BACKGROUND: Polyp assessment is multimodal and is vital prior to endoscopic mucosal resection. The size, morphology, site and access (SMSA) score has been validated in specialist endoscopic institutions. this study investigated the ability of this score to predict incomplete endoscopic resection of large colorectal polyps in a district general hospital. METHODS: Consecutive patients undergoing endoscopic mucosal resection of large (≥ 20 mm) colorectal polyps at Worthing Hospital. Clinical, endoscopic and histological data were taken from prospective databases. The primary outcome of the study was to investigate the correlation of the SMSA score with incomplete endoscopic resection. RESULTS: Between February 2015 and August 2018, 114 patients underwent colorectal endoscopic mucosal resection. Of these, 67 (59%) were male. The median (interquartile range) age of the study population was 72 years (65-78 years). Some 17 lesions (15%) were pedunculated, 76 (67%) were sessile and 21 were (18%) flat; 84 polyps (77%) were located in the left colon/rectum, with the remainder in the right colon; 51 lesions (45%) were 20-30 mm, 27 (24%) were 30-40 mm and 36 (31%) were greater than 40 mm in diameter. When reclassified into the SMSA score, 9 of the polyps (8%) were level 2, 64 (56%) were level 3 and 41 (36%) were level 4. Incomplete resection was clinically diagnosed in 9/114 (8%). The SMSA score was positively correlated with incomplete endoscopic resection, but not with additional procedure usage, complications or advanced histology. CONCLUSIONS: Many patients with large polyps can be managed outside of specialist units. This study has validated that the SMSA score was associated with incomplete endoscopic mucosal resection for large polyps in a district general hospital setting.

Adenoid cystic carcinoma of the sublingual salivary gland in a 16-year-old female--report of a case and review of the literature.

Tumours of the sublingual salivary gland are exceptionally rare. The present case report describes an adenoid cystic carcinoma of the sublingual salivary gland occurring in a 16-year-old girl, in itself an uncommon event. In addition, an interesting feature of the presentation was obstruction of the ipsilateral submandibular gland due to involvement of Wharton's duct.

A meta-analysis comparing tacker mesh fixation with suture mesh fixation in laparoscopic incisional and ventral hernia repair.

OBJECTIVE: To systematically compare the tacker mesh fixation (TMF) with the suture mesh fixation (SMF) in laparoscopic incisional and ventral hernia (LIVH) repair. METHODS: Trials evaluating the TMF with the SMF in LIVH repair were analysed using the statistical tool RevMan(®). Combined dichotomous and continuous data were expressed as odds ratio (OR) and mean difference (MD), respectively. RESULTS: Four trials (2 randomised and 2 non-randomised) encompassing 207 patients undergoing LIVH repair with TMF versus SMF were retrieved from the standard electronic databases and analysed systematically. Ninety-nine patients underwent TMF and 108 patients underwent SMF in LIVH repair. There was no statistically significant heterogeneity (p = 0.27)] among trials. In the fixed-effects model, LIVH repair with TMF was associated with shorter operation time (MD, -23.65; 95 % CI, -31.06, -16.25; z = 6.26; p < 0.00001). Four- to six-week postoperative pain score was significantly lower (MD, -0.69; 95 % CI, -1.16, -0.23; z = 2.92; p < 0.004) following TMF. Peri-operative complications (p = 0.65), length of hospital stay (p = 1) and risk of hernia recurrence (OR, 1.54; 95 % CI, 0.38, 6.27; z = 0.61; p = 0.54) following TMF and SMF were statistically not different. CONCLUSION: TMF in LIVH repair is associated with shorter operative time and lesser postoperative pain. TMF is comparable with SMF in terms of peri-operative complications, length of hospital stay and hernia recurrence. Therefore, TMF may be used in LIVH repair. However, further randomised trials recruiting higher number of patients are required to validate these findings.

A systematic review on the effectiveness of slowly-absorbable versus non-absorbable sutures for abdominal fascial closure following laparotomy.

OBJECTIVE: To systematically analyse the effectiveness of delayed-absorbable (Polydioxanone; PDS) versus non-absorbable (Polypropylene; Prolene, and Nylon) for abdominal fascial closure in patients undergoing laparotomy. METHODS: Randomised trials evaluating PDS versus Prolene/Nylon for abdominal fascial closure were selected and analysed by using the statistical tool RevMan where summative data was expressed as odds ratio (OR). RESULTS: Eight randomised trials encompassing 4261 patients undergoing laparotomy closure with either PDS or Prolene/Nylon were retrieved. There was no statistically significant heterogeneity among trials. In the fixed effect model PDS was comparable to Prolene/Nylon in terms of risk of incisional hernia (OR, 1.10; 95% CI, 0.87, 1.37; z = 0.79; p = 0.43), wound dehiscence (OR, 1.04; 95% CI, 0.67, 1.62; z = 0.19; p = 0.85), peri-operative complications (OR, 0.94; 95% CI, 0.66, 1.33; z = 0.37; p = 0.71), suture sinus formation (OR, 0.58; 95% CI, 0.33, 1.04; z = 1.84; p = 0.07) and surgical site infection (OR, 0.98; 95% CI, 0.68, 1.39; z = 0.14; p = 0.89). Subgroup analysis separately comparing Prolene and Nylon with PDS supported same outcome. CONCLUSION: PDS and Prolene/Nylon are equally effective for the closure of abdominal fascia following laparotomy. Given that there are no significant differences between two suture materials, further studies may be conducted to evaluate their cost-effectiveness and measurement of health-related quality of life instead of analysing their effectiveness in laparotomy closure.

Intraoperative oesophageal Doppler guided fluid management shortens postoperative hospital stay after major bowel surgery.

BACKGROUND: Occult hypovolaemia is a key factor in the aetiology of postoperative morbidity and may not be detected by routine heart rate and arterial pressure measurements. Intraoperative gut hypoperfusion during major surgery is associated with increased morbidity and postoperative hospital stay. We assessed whether using intraoperative oesophageal Doppler guided fluid management to minimize hypovolaemia would reduce postoperative hospital stay and the time before return of gut function after colorectal surgery. METHODS: This single centre, blinded, prospective controlled trial randomized 128 consecutive consenting patients undergoing colorectal resection to oesophageal Doppler guided or central venous pressure (CVP)-based (conventional) intraoperative fluid management. The intervention group patients followed a dynamic oesophageal Doppler guided fluid protocol whereas control patients were managed using routine cardiovascular monitoring aiming for a CVP between 12 and 15 mm Hg. RESULTS: The median postoperative stay in the Doppler guided fluid group was 10 vs 11.5 days in the control group P<0.05. The median time to resuming full diet in the Doppler guided fluid group was 6 vs 7 for controls P<0.001. Doppler patients achieved significantly higher cardiac output, stroke volume, and oxygen delivery. Twenty-nine (45.3%) control patients suffered gastrointestinal morbidity compared with nine (14.1%) in the Doppler guided fluid group P<0.001, overall morbidity was also significantly higher in the control group P=0.05. CONCLUSIONS: Intraoperative oesophageal Doppler guided fluid management was associated with a 1.5-day median reduction in postoperative hospital stay. Patients recovered gut function significantly faster and suffered significantly less gastrointestinal and overall morbidity.

Schwannoma of the anterior cranial fossa and paranasal sinuses.

Only two cases of schwannomas involving the anterior cranial fossa and paranasal sinuses or nasal fossa have been reported previously. We describe a third case which involved all of these structures and also the left orbit.

Colonoscopic surveillance after curative colorectal resection: results of an empirical surveillance programme.

INTRODUCTION: Colonoscopic surveillance after colorectal cancer resection is widely practised despite little evidence that it improves survival. The optimum protocol for colonoscopic follow-up after colorectal cancer resection has not yet been elucidated. We audited the outcome of an empirical colonoscopic follow-up programme in a cohort of patients who underwent colorectal resection with a minimum of five years follow-up to establish patterns of metachronous neoplasia and suitable surveillance intervals. METHODS: The colonoscopic records, biopsy results and follow-up details of patients diagnosed with colorectal cancer between June 1990 and June 1996 were reviewed. The number and type of metachronous neoplastic lesions diagnosed was recorded. Rates of development of new neoplasms were estimated by calculating the time from operation to their first discovery. Factors predictive of further development of polyps or cancer were sought. Results were compared to published reports of intensive follow-up programmes. RESULTS: Seven hundred and ninety-eight patients underwent colorectal resection with curative intent during the study period. 226 patients had one or more follow-up colonoscopies (mean time post resection 48.8 months). In total 352 colonoscopies, encompassing 1437 patient years of surveillance, were performed. Nine metachronous cancers in eight patients, five of which were asymptomatic were diagnosed by colonoscopy at a mean of 63 months. Three asymptomatic recurrences were diagnosed but all were inoperable. 70 (31%) patients had adenomatous polyps diagnosed after a mean time from operation of 34 months for simple adenomatous polyps and 21 months for those with advanced features. Patients with multiple polyps or advanced polyps at the initial colonoscopy were more likely to form subsequent polyps. Only 5.8% of patients with a single adenoma or a normal colon formed an advanced adenoma over the next 36 months of surveillance. CONCLUSION: The results of an empirical colonoscopic follow-up programme compared favourably to the results of the intensive programmes reported in the literature. Most patients are at very low risk of developing significant colonic pathology over the first five years after resection. Colonoscopic surveillance intervals need not be less than five years unless the patient has multiple adenomas or advanced adenomas at the first colonoscopy. Three yearly surveillance intervals are most probably adequate in these individuals.
