The addition of gum chewing to a standardized postoperative regimen did not reduce the period of postoperative ileus or shorten length of stay following open surgery for left-sided colorectal cancer.

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.

Stapled hemorrhoidectomy (mucosectomy) is a new technique that has recently been introduced for the treatment of third-degree and fourth-degree hemorrhoids and rectal mucosal prolapse. We present a case of severe retroperitoneal sepsis complicating stapled hemorrhoidectomy that was successfully treated by conservative means, further surgery therefore being avoided. The literature on the more serious complications associated with stapled hemorrhoidectomy is reviewed.

BACKGROUND: Despite ongoing debates, there is still no consensus regarding where to divide the inferior mesenteric artery for oncological reasons in rectal cancer: at its origin from the aorta (high ligation) or distal to the origin of the left colic artery (low ligation). OBJECTIVES: The purpose of this study was to compare the outcomes of high and low ligation of the inferior mesenteric artery in rectal cancer surgery. DATA SOURCES: MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, World Health Organization International Clinical Trials Registry, ClinicalTrials.gov, and ISRCTN Register were searched. STUDY SELECTION: andomized controlled trials investigating outcomes of curative anterior resection in patients with cancer of the rectum were included. INTERVENTIONS: High ligation of the inferior mesenteric artery was compared with low ligation technique. MAIN OUTCOME MEASURES: We measured the total number of lymph nodes harvested, anastomotic leak, postoperative complications, postoperative mortality, operative time, intraoperative blood loss, conversion to open surgery, overall survival, and disease-free survival. RESULTS: Analysis of 1102 patients from 8 trials suggested no difference between high and low ligation of the inferior mesenteric artery in terms of total number of lymph nodes harvested (mean difference = –0.87; p = 0.26), anastomotic leak (OR = 1.39; p = 0.15), postoperative complications (OR = 1.39; p = 0.78), postoperative mortality (risk difference = –0.00; p = 0.48), operative time (mean difference = –1.99; p = 0.79), intraoperative blood loss (mean difference = –2.28; p = 0.77), conversion to open surgery (risk difference = 0.01; p = 0.48), 5-year overall survival (OR = 0.76; p = 0.32), 5-year disease-free survival (OR = 0.88; p = 0.58), overall survival at maximum follow up (OR = 0.80; p = 0.43), and disease-free survival at maximum follow-up (OR = 0.83; p = 0.35). LIMITATIONS: Limited data were available on functional and long-term survival outcomes. CONCLUSIONS: There is no difference between high and low ligation of the inferior mesenteric artery in terms of oncological outcomes or postoperative morbidity and mortality. The available evidence is subject to potential confounding by the use of neoadjuvant therapy, adjuvant therapy, disease stage, location of tumor, and use of protective stoma. Functional outcomes including postoperative bowel, urinary and sexual function, and long-term survival outcomes should be the outcome of study in future trials.

Magnetic resonance imaging has good specificity and negative predictive value for predicting an uninvolved CRM post downstaging CRT in locally advanced rectal cancer although sensitivity and positive predictive value for an involved CRM were unsatisfactory. The shortcomings of MRI stem from poor differentiation of viable tumour from posttreatment changes and inability to identify small nodal and tumour deposits. Clinical correlates in this group of patients have confirmed the importance of achieving a clear CRM at surgery.

INTRODUCTION To report our initial experience of laparostomy and immediate intra-abdominal vacuum therapy in patients with severe peritonitis due to intra-abdominal catastrophes. PATIENTS AND METHODS Twenty-seven patients underwent emergency laparotomy and laparostomy formation with the application of immediate intra-abdominal TRAC-VAC ® therapy (male:female ratio, 1:1.2; median age, 73 years; range, 34-84 years). Predicted mortality was assessed using the P-POSSUM score and compared with clinically observed outcomes. RESULTS Ten patients (37%) with a mean predicted P-POSSUM mortality of 72%, died of sepsis and multi-organ failure. Seventeen patients (mean P-POSSUM 48% expected mortality) survived to discharge. One patient with pancreatitis died from small bowel obstruction 1-year post discharge, two patients developed a small bowel fistula. One patient had an allergic reaction to the VAC dressing. Our patients, treated with laparostomy and TRAC VAC therapy, had a significantly improved observed survival when compared to P-POSSUM expected survival (P = 0.004). CONCLUSIONS Laparostomy with immediate intraperitoneal VAC therapy is a robust and effective system to manage patients with intra-abdominal catastrophes. There were significantly improved outcomes compared to the mortality predicted by P-POSSUM scores. Damage control surgery with laparostomy formation and intra-abdominal VAC therapy should be considered in patients with severe peritonitis.
