ABSTRACT
AIM: Single-incision (or port) laparoscopic surgery (SILS) has recently emerged as a method to improve morbidity and cosmetic benefit of conventional laparoscopic surgery. The literature contains two reports of SILS right hemicolectomy, and we report our experience of this technique. METHOD: Seven consecutive, unselected patients underwent SILS retrocaecal appendicectomy, right hemicolectomy, extended right hemicolectomy, colectomy with ileorectal anastomosis, proctocolectomy, anterior resection and restorative proctocolectomy/ileoanal pouch using a single Triport (Olympus Keymed, Southend, UK), conventional instrumentation and nerve block analgesia. Three had undergone previous surgery, two had cancer and two were immunosuppressed. RESULTS: Umbilical, right- and left-iliac fossa SILS was feasible using conventional instruments. Operative time ranged between 23 and 195 min (median 48 min). Four patients tolerated normal diet within 6 h (12-16 h for the remainder). Only one patient required postoperative enteral morphine (10 mg × 4). Discharge occurred between 8 and 90 h (median 16 h) of surgery. A secondary haemorrhage from the ileorectal anastomosis was managed conservatively. CONCLUSION: SILS colorectal resection is feasible and safe when performed by an experienced laparoscopic surgeon and theatre team. It may have advantages over conventional laparoscopic surgery in terms of reduced pain, lower cost, faster recovery and cosmesis.

OBJECTIVE: Debate exists as to the benefits of performing mucosectomy as part of pouch surgery for ulcerative colitis (UC) and familial adenomatous polyposis (FAP). Whilst mucosectomy results in a more complete removal of diseased mucosa, this benefit may be at the price of poorer function. We examined these issues. METHOD: Using Medline, Embase, Ovid and Cochrane database searches papers were identified relating to the outcome following pouch surgery with and without mucosectomy. Potential reasons for functional problems were investigated, as were rates of 'cuffitis', dysplasia, polyposis and cancer in the ileal pouch and anal canal. RESULTS: The available evidence suggests that performing a mucosectomy leads to a worse functional outcome. Meta-analysis suggested that nighttime seepage of stool and resting and squeeze pressure were worse after mucosectomy. The most likely reason for functional impairment following pouch surgery was the degree of anal manipulation. Mucosectomy does seem to confer benefit in terms of disease control but this benefit does not reach statistical significance. CONCLUSION: Stapled anastomosis avoiding mucosectomy is the approach of choice for ileal pouch anal anastomosis because this leads to superior functional outcome. Performing mucosectomy results in some clinical benefits in terms of lower rates of inflammation and dysplasia in the retained mucosa in UC patients and lower rates of cuff polyposis in FAP patients. However, on the basis of available evidence mucosectomy is only indicated in those cases where the patient is at a high risk of disease in the retained rectal cuff.

BACKGROUND: Patients with ulcerative colitis are at a higher risk of developing colorectal cancer than those without the disease. Surveillance programmes are used routinely to detect dysplasia and cancer in patients with ulcerative colitis. However, such programmes are poorly effective. This article discusses possible improvements suggested by recent research. METHODS: Papers relating to cancer associated with ulcerative colitis and surveillance programmes to detect such cancer were identified using Medline searches. Further papers were identified from the reference lists of identified papers. RESULTS: The probability of cancer for all patients with ulcerative colitis regardless of disease extent was 2 per cent at 10 years, 8 per cent at 20 years and 18 per cent at 30 years; the overall prevalence of colorectal cancer in any patient was 3.7 per cent. Indications for colonoscopic surveillance are extensive disease for 8-10 years, especially in those with active inflammation, a family history of colorectal cancer and primary sclerosing cholangitis. Problems affecting surveillance include the diagnosis of dysplasia, difficulty in differentiating 'sporadic' adenomas from a dysplasia-associated lesion or mass, and decision making based on surveillance findings. Molecular genetic and endoscopic advances to alleviate these problems are discussed. CONCLUSION: Rates of detection of dysplasia can be improved by chromoendoscopy. Molecular genetics has the potential to identify patients most at risk of cancer and can differentiate between different types of lesion.

Anastomotic leaks following colorectal surgery may be divided into those which are clinically significant and those which are not. Leakage occurs in 3.4-6% of all colorectal cases. It is most commonly associated with rectal anastomoses, being clinically significant in 2.9-15.3% of cases. Mortality following a leak may be 6.0-39.3%. There is no evidence that preoperative bowel preparation reduces the rate and consequences of leaks. There is no evidence for the use of drains when an anastomosis has been made outside the pelvis, but pelvic drainage may be important after anterior resection. The use of covering stomas has not been shown to reduce leak rate but does mitigate the clinical effects of leaks. Prompt diagnosis and further laparotomy can reduce mortality following leakage. Intra-abdominal abscesses can in most cases be treated by radiologically guided drainage. Anastomotic leaks are the most common cause of anastomotic strictures and are also associated with increased rates of local recurrence of cancer.

BACKGROUND: The aim of this study was to determine whether the morphology of rectal cancer predicts outcome following treatment by local excision, and whether morphology should therefore be added to the criteria presently used for case selection. METHODS: The hospital notes and histological findings of 91 patients who had undergone a local surgical procedure for rectal cancer were reviewed retrospectively. Eight patient and tumour characteristics including morphology were analysed with respect to 5-year survival, local recurrence and cancer-specific death within 5 years. Morphology was divided into four types: polypoid, sessile, ulcerated and flat raised. RESULTS: Survival and local recurrence were significantly better for patients with exophytic (polypoid and sessile) carcinomas than for those with non-exophytic (ulcerated and flat raised) lesions. Multivariate logistic regression analysis showed that age, depth of invasion, lymphatic invasion and venous invasion were significant predictors of outcome. The exophytic group included significantly more stage T1 and fewer T2 and T3 cancers, and a significantly smaller proportion of tumours that showed venous and lymphatic invasion than the non-exophytic group. CONCLUSION: Morphology is a clinical guide to prognosis after local excision. Non-exophytic cancers are associated with high-risk histopathological features that render tumours of this type unsuitable for local excision.

A 41-year-old man developed severe hepatic dysfunction following a 3.5-week course of terbinafine (250 mg/day). He suffered marked pruritus, jaundice, malaise, anorexia and loin pain. Serum bilirubin rose to a peak value of 718 micromol/l with alkaline phosphatase at 569 U/l, alanine aminotransferase at 90 U/l, aspartate aminotransferase at 63 U/l and a prolonged prothrombin time of 21 s, unresponsive to vitamin K. Transjugular liver biopsy showed canalicular cholestasis consistent with a drug reaction. Symptoms resolved 11 months after drug cessation, with liver function tests returning to normal values after 15 months. This case represents the most severe cholestatic reaction reported to date, resulting in patient recovery without liver transplantation. A comprehensive literature review is provided.

This case history presents not only the therapists' point of view but also the client's. Four critical periods during therapy with a shoe fetishist were described by the two therapists and the client. The results of this procedure suggest that it is a facilitating method of gaining insight into the therapeutic process.
