To succeed, large national quality improvement programmes need to allow for differences between hospitals and ensure teams have both the time and resources needed to improve patient care.

Background Radical surgery via total mesorectal excision might not be the optimal first-line treatment for early-stage rectal cancer. An organ-preserving strategy with selective total mesorectal excision could reduce the adverse effects of treatment without substantially compromising oncological outcomes. We investigated the feasibility of recruiting patients to a randomised trial comparing an organ-preserving strategy with total mesorectal excision.Methods TREC was a randomised, open-label feasibility study done at 21 tertiary referral centres in the UK. Eligible participants were aged 18 years or older with rectal adenocarcinoma, staged T2 or lower, with a maximum diameter of 30 mm or less; patients with lymph node involvement or metastases were excluded. Patients were randomly allocated (1:1) by use of a computer-based randomisation service to undergo organ preservation with short-course radiotherapy followed by transanal endoscopic microsurgery after 8-10 weeks, or total mesorectal excision. Where the transanal endoscopic microsurgery specimen showed histopathological features associated with an increased risk of local recurrence, patients were considered for planned early conversion to total mesorectal excision. A non-randomised prospective registry captured patients for whom randomisation was considered inappropriate, because of a strong clinical indication for one treatment group. The primary endpoint was cumulative randomisation at 12, 18, and 24 months. Secondary outcomes evaluated safety, efficacy, and health-related quality of life assessed with the European Organisation for Research and Treatment of Cancer (EORTC) QLQ C30 and CR29 in the intention-to-treat population. This trial is registered with the ISRCTN Registry, ISRCTN14422743.

The aim of this study was to compare quality of life after total gastrectomy (TG) with that after subtotal gastrectomy (STG) for gastric carcinoma. The value of the routine use of TG de principe in the treatment of gastric carcinoma, wherever the tumor may be sited in the stomach, remains controversial. The advocates of TG contend that when it can be performed safely, with relatively low operative mortality and morbidity, it yields better long-term survival than STG. Most surgeons, however, believe that the routine use of TG increases both operative mortality and morbidity and the risk of nutritional deficiency in the long term, without improving survival. TG may also be associated with poorer outcome in terms of quality of life (QOL), but the evidence for this is tenuous. Forty-seven consecutive patients who had undergone potentially curative (R0) gastric resection for carcinoma were studied: 26 had undergone TG and 21 STG. A radical D2 lymph node dissection had been performed in each, and all patients were free from recurrence at the time of the study. QOL was measured before operation and 1, 3, 6, and 12 months after operation by means of five questionnaires to measure functional outcome: the Rotterdam symptom checklist (RSCL), the Troidl index, the hospital anxiety and depression (HAD) scale, activities of daily living score, and Visick grades. Before operation there was no significant difference in QOL between the two groups of patients. At 1 year after operation, however, patients who had undergone STG had a significantly better QOL than patients who had undergone TG: Their median RSCL score was lower (10 versus 19 respectively, p < 0.05), and their Troidl index was higher (11 versus 9 respectively, p < 0.05). The QOL of patients who underwent STG was also significantly better after operation than it had been before operation, whereas the QOL of the TG group was not significantly better after operation than before operation. The QOL of patients was found to be significantly better after STG than after TG for gastric carcinoma. Because operative mortality is greater and long-term survival is no better after TG than after STG, the latter is recommended as the treatment of choice for tumors of the distal stomach.

Consensus guidelines on how to report laparoscopic surgery videos for educational purposes have been developed. We anticipate that following our guidelines could help to improve video quality.These reporting guidelines may be useful as a standard for reviewing videos submitted for publication or conference presentation.

One hundred and ninety five consecutive, potentially curative resections for adenocarcinoma of the stomach were performed in one surgical department between 1970 and 1989: 76 patients underwent gastrectomy with splenectomy and 119 gastrectomy without splenectomy. Operative mortality was 12% after gastrectomy with splenectomy, but only 2/5% after gastrectomy without splenectomy (p<0.05). Postoperative complications were also significantly more common when splenectomy was combined with gastrectomy (41% v 14%, p

Surgery, trauma and anaesthesia induce a state of transient immunosuppression. Laparoscopic cholecystectomy has several well documented clinical advantages over traditional cholecystectomy and provokes a lower acute phase response, thought to be a result of the smaller wound size. The influence of laparoscopic cholecystectomy (21 patients) and conventional open cholecystectomy (13 patients) upon components of the cell-mediated immune system was investigated. Cell-mediated immunity was studied by in vitro assays of T lymphocyte proliferation to different mitogens, and by natural killer cell cytotoxicity using a standard 51Cr release assay. Blood samples were taken before and 24 h after the start of the operation. In the sample taken after operation there was significant depression of T lymphocyte proliferation to phytohaemagglutinin (stimulation index 149.4 versus 33.3, P < 0.002), staphylococcal enterotoxin B (85.2 versus 52.6, P = 0.01) and toxic shock syndrome toxin (48.4 versus 14.8, P = 0.08) in the group of patients who underwent open surgery, but not in the group treated by laparoscopic surgery. There was a small but statistically insignificant decrease of natural killer cell cytotoxicity in both groups of patients. These findings suggest that laparoscopic cholecystectomy causes less depression of cell-mediated immunity than open cholecystectomy.
