RESUMO
AIM: A 'watch and wait' (W&W) strategy after neoadjuvant long-course chemoradiotherapy (NACRT) remains controversial. Whilst encouraging short-term data exist, the strategy will be judged on long-term data. We present long-term, real-world UK data from a single National Health Service trust. METHODS: An analysis was performed of a prospectively maintained W&W database over 9 years between 2010 and 2018. Outcome measures include incidence and time to regrowth and overall and disease-free survival. RESULTS: We diagnosed 563 rectal cancers in 9 years. In all, 283 patients underwent rectal resection (50.3%). NACRT was used in 155 patients for margin-threatened tumours on staging MRI. Forty-nine patients (31.6%) experienced either a 'near complete' or a complete clinical response (cCR) at their 10 weeks post-NACRT assessment (MRI and endoscopy). The median age was 69 years (range 44-83), and the male to female ratio was 32:17. The median follow-up was 38 months (range 12-96). The median tumour distance from the anal verge was 7 cm (1-15 cm). Twenty-two patients had a cCR on initial assessment and 27 patients had a 'near' cCR. Of those 27 who experienced a 'near' cCR, 17 (63%) progressed to cCR on repeat assessment and 10 (37%) did not. Of these 10 patients, seven underwent standard surgical resection and three were unfit for surgery. R0 for the seven with delayed resection was 100%. Of 39 patients (22 cCR and 17 'near' cCR who progressed to cCR) (25.2% of those receiving NACRT), six patients experienced local regrowth (15.4%). The median time to local regrowth was 29 months (15-60 months). One of these six patients underwent salvage abdominoperineal resection, one was advised to have contact radiotherapy and four opted against surgery and also had contact radiotherapy. The overall survival was 100% at 2 years and 90% at 5 years. Disease-free survival was 90.47% at 2 years and 74.8% at 5 years. CONCLUSION: A W&W treatment strategy was employed safely in this patient cohort with acceptable rates of local regrowth and survival.

OBJECTIVE: The aim of this study was to analyse the outcome of emergency laparoscopic surgical management of complicated diverticular disease. METHOD: A prospectively collected electronic database of all colorectal laparoscopic procedures between April 2001 and September 2007 has been used to identify outcomes in patients presenting with complicated diverticular disease. RESULTS: Sixty-six patients (28 men), median age 69 years (23-95), ASA grade II (12), III (38), IV (16) have undergone emergency surgery for complicated diverticulitis--Hinchey grades I (27), II (29), III (7) and diverticular bleeding (3) over a 6(1/2)-year period: 43 high anterior resections, 17 Hartmann's resections and seven low anterior resections. Diverticular fistulas were seen in 16 patients: colovaginal (7), colovesical (2), colo-fallopian (4), entero-colic (3). The median operation time was 110 min (45-195 min). There was one conversion to open surgery. Postoperative analgesia was provided by intravenous Paracetamol in 33 patients (50%), patient-controlled analgesia in 24 (36%), oral Paracetamol and Oramorph (12%) and epidural opioid infusion (1.5%). The median time to normal diet was 24 h (4 h-6 days) and median hospital stay 5 days (2-30). There were two deaths (3.3%); anastomotic leak, ventricular fibrillation (VF) cardiac arrest. Other complications included: wound infection eight (12%), anastomotic leak four (8%), port-site hernia one and one case of Clostridium difficile colitis requiring colectomy. There were five (7.5%) returns to theatre and two readmissions (3%). CONCLUSION: Laparoscopic resectional surgery in complicated diverticular disease is a feasible, safe and a largely predictable operation that allows for early hospital discharge and, in our opinion, improved patient care. We are encouraged to continue to offer our patients the option of an emergency laparoscopic resection.

BACKGROUND: During surgery for left colonic and rectal cancers, the inferior mesenteric artery (IMA) can be ligated either at its aortic origin (high tie) or below the origin of the left colic artery (low tie). There is no consensus as to which method should be employed. METHODS: We searched Medline, EMBASE, Cochrane collaboration, and National Guidelines Clearinghouse databases and undertook a systematic review on the use of IMA high tie during curative resections for left colonic and rectal cancers and its impact on patient survival, peri-operative morbidity and mortality, and lymph node retrieval rates. RESULTS: Sixteen studies were eligible for systematic review, including one randomized controlled study, 7 quasi-experimental studies, and 8 retrospective cohort studies. Data on 7,649 patients were analyzed, of whom 4,847 underwent high ligation of the IMA. Despite a trend for improved survival in patients in whom high tie was employed, there is no conclusive evidence to support this. Mortality and morbidity, including anastomotic leak and autonomic nerve injury rates, are similar, while lymph node retrieval is improved. CONCLUSIONS: Although there is no undisputable evidence of improved survival, the use of IMA high tie contributes to improved lymph node retrieval rates and accuracy of tumour staging.
