ABSTRACT
Purpose The NHS Bowel cancer screening programme (NHSBCSP) aims to reduce colorectal cancer (CRC) cumulative mortality by up to 23 per cent; long-term outcomes at national level are not yet known. The purpose of this paper is to examine a local population of CRC patients of screening age for their characteristics and long-term survival in relation to their presentation, including through the NHSBCSP. Design/methodology/approach Retrospective analysis of a prospectively maintained CRC database for the years 2009-2014 in a single district hospital providing bowel cancer screening and tertiary rectal cancer services. Findings Of 528 CRC patients diagnosed in the screening age range, 144(27.3 per cent) presented through NHSBCSP, 308(58.3 per cent) electively with symptoms and 76(14.4 per cent) as emergency. NHSBCSP-diagnosed patients were younger (median 66 vs 68 and 69 years, respectively, p=0.001), had more often left-sided cancers (59(41.0 per cent) vs 82(26.6 per cent) and 24(31.6 per cent), respectively, p=0.001), more UICC-stage I (42(29.2 per cent) vs 49(15.9 per cent) and 2(2.6 per cent)), stage III (59(41.0 per cent) vs 106(34.4 per cent) and 20(26.3 per cent)) and less stage IV disease (8(5.6 per cent) vs 61(19.8 per cent) and 34 (44.7 per cent), respectively, p<0.001). Three-year overall survival was best for NHSBCSP and worst for emergency patients (87.5 per cent vs 69.0 per cent and 35.3 per cent, respectively, LogRank p<0.001). Originality/value Patients diagnosed within the NHSBCSP have improved outcome compared to both symptomatic elective and emergency presentations. A reduction in overall cumulative mortality in order of 25 per cent may well be achieved, but continuing high levels of emergency presentations and undetected right-sided disease emphasise need for further improvement in public participation in the NHSBCSP and research into more sensitive and acceptable alternative screening methods.

Purpose Higher caseloads are associated with better outcomes for many conditions treated in secondary and tertiary care settings, including colorectal cancer (CRC). There is little known whether such volume-outcome relationship exist in primary care settings. The purpose of this paper is to examine general practitioner (GP) CRC-specific caseload for possible associations with referral pathways, disease stage and CRC patients' overall survival. Design/methodology/approach The paper retrospectively analyses a prospectively maintained CRC database for 2009-2014 in a single district hospital providing bowel cancer screening and tertiary rectal cancer services. Findings Of 1,145 CRC patients, 937 (81.8 per cent) were diagnosed as symptomatic cancers. In total, 210 GPs from 44 practices were stratified according to their CRC caseload over the study period into low volume (LV, 1-4); medium volume (MV, 5-7); and high volume (HV, 8-21 cases). Emergency presentation (LV: 49/287 (17.1 per cent); MV: 75/264 (28.4 per cent); HV: 105/386 (27.2 per cent); p=0.007) and advanced disease at presentation (LV: 84/287 (29.3 per cent); MV: 94/264 (35.6 per cent); HV: 144/386 (37.3 per cent); p=0.034) was more common amongst HV GPs. Three-year mortality risk was significantly higher for HV GPs (MV: (hazard ratio) HR 1.185 (confidence interval=0.897-1.566), p=0.231, and HV: HR 1.366 (CI=1.061-1.759), p=0.016), but adjustment for emergency presentation and advanced disease largely accounted for this difference. There was some evidence that HV GPs used elective cancer pathways less frequently (LV: 166/287 (57.8 per cent); MV: 130/264 (49.2 per cent); HV: 182/386 (47.2 per cent); p=0.007) and more selectively (CRC/referrals: LV: 166/2,743 (6.1 per cent); MV: 130/2,321 (5.6 per cent); HV: 182/2,508 (7.3 per cent); p=0.048). Originality/value Higher GP CRC caseload in primary care may be associated with advanced disease and poorer survival; more work is required to determine the reasons and to develop targeted intervention at local level to improve elective referral rates.

A 29-year-old woman with known history of endometriosis was referred to colorectal outpatient clinic from gynaecology with a history of intermittent rectal bleeding and no associated bowel symptoms. Flexible sigmoidoscopy in concordance with pelvic MRI revealed a 3×2×2â cm sessile lesion in the anterior rectal wall. The lesion was also palpable as a firm mass on digital rectal examination. From the gynaecological point of view no intra-abdominal exploration was required; the sole rectal wall lesion was removed with the minimally invasive surgical technique of transanal endoscopic microsurgery. Full thickness rectal wall excision sample was reported to be histologically complete and confirmed endometriosis. No recurrence was detected at endoscopic follow-up at 6â months. The patient remained symptom free. Therefore, we demonstrated a case of minimally invasive removal of a rectal wall large endometriosis nodule in a fertile woman with a complete, symptomatic, uneventful recovery.

Colouterine fistula as a potential complication of chronic diverticulitis is a rare entity with less than 30 cases reported worldwide. Generally, patients require a multidisciplinary approach including a major laparotomy with hysterectomy and sigmoid colectomy, and, occasionally, temporary colostomy. We report the first attempt of a novel, minimally invasive technique for managing a case of benign colouterine fistula with single-incision laparoscopic (SIL) sigmoid colectomy and uterus preservation. A small, 3â cm incision site provided access for the whole operation, as well as played a role as the specimen extraction site. Malignant fistulas and large uterine defects may require hysterectomy, however, laparoscopic closure of uterine wall defects can be considered as a reasonable alternative in selected patients, avoiding the higher risks associated with hysterectomy and keeping fertility at younger ages. Single incision laparoscopy in complicated diverticular disease and fistula formation cases is a challenging but technically feasible option, in experienced hands.

BACKGROUND: The treatment of complex fistulae-in-ano is challenging and often includes a number of operations due to high rates of recurrence. Recently, techniques using in vitro expanded adipose tissue-derived stem cells have been described. We describe a novel treatment for cryptoglandular fistulae used in 7 patients, using a combination of surgical closure of the internal opening and real-time autologous adipose tissue-derived regenerative cells (ADRC)-enhanced lipofilling, without need for in vitro expansion. METHODS: Following exclusion of active perianal sepsis, patients underwent a standard tumescent liposuction procedure, harvesting ~300 to 400 mL of raw lipoaspirate. The lipoaspirate was prepared in real time, using the Celution 800/CRS system to obtain the stromal vascular fraction containing ADRCs. After excision of the fistula tract and closure of the internal orifice, fresh ADRC-enhanced lipoaspirate was injected into and around the fistula tract. RESULTS: At 6-months' follow-up, 5 of 7 (71.4%) patients showed clinical signs of fistula closure; one of these patients had a recurrence at 10 months due to sepsis. The remaining 4 patients (57.1%) all had complete fistula closure at a median of 46 months' follow-up. There were no adverse events associated with the technique, and no new incontinence. CONCLUSION: Treatment of cryptoglandular fistulae-in-ano with ADRC-enhanced lipofilling appears feasible and safe, and may add to the range of procedures that can be used to treat this difficult problem.

The treatment of complex fistulae-in-ano is challenging and often includes a number of operations due to high rates of recurrence. We report the successful treatment of three consecutive patients with long-standing cryptoglandular fistula-in-ano with a novel combination of mucosal advancement flap and adipose-tissue derived regenerative cells (ADRCs) from the stromal vascular fraction (SVF) obtained from a simple lipoaspiration procedure, using Celution technology. There was no operative morbidity; one patient who had a colostomy for faecal diversion has since undergone restoration of bowel continuity. All thee fistulae remain healed at 2-3-year follow-up. Lipofilling of cryptoglandular fistulae-in-ano with ADRC-enhanced lipofilling appears feasible and safe, and may add to the range of procedures that can be used to treat this difficult problem.
