Intraoperative colonic pulse oximetry in left-sided colorectal surgery : can it predict anastomotic leak?

An anastomotic leak is a fairly common and a potentially lethal complication in colorectal surgery. Objective methods to assess the viability and blood circulation of the anastomosis could help in preventing leaks. Intraoperative pulse oximetry is a cheap, easy to use, fast, and readily available method to assess tissue viability. Our aim was to study whether intraoperative pulse oximetry can predict the development of an anastomotic leak. The study was a prospective single-arm study conducted between the years 2005 and 2011 in Helsinki University Hospital. Patient material consisted of 422 patients undergoing elective left-sided colorectal surgery. The patients were operated by one of the three surgeons. All of the operations were partial or total resections of the left side of the colon with a colorectal anastomosis. The intraoperative colonic oxygen saturation was measured with pulse oximetry from the colonic wall, and the values were analyzed with respect to post-operative complications. 2.3 times more operated anastomotic leaks occurred when the colonic StO(2) was Low intraoperative colonic StO(2) values are associated with the occurrence of anastomotic leak. Despite its handicaps, the method seems to be useful in assessing anastomotic viability.Peer reviewe

Does ventral rectopexy improve pelvic floor function in the long term?

Abstract Background: Information is needed on long-term functional results, sequelas, and outcome predictors for laparoscopic ventral mesh rectopexy. Objective: The purpose of this study was to evaluate long-term function postventral rectopexy in patients with external rectal prolapse or internal rectal prolapse in a large cohort and to identify the possible effects of patient-related factors and operative technical details on patient-reported outcomes. Design: This was a retrospective review with a cross-sectional questionnaire study. Settings: Data were collated from prospectively collected registries in 2 university and 2 central hospitals in Finland. Patients: All 508 consecutive patients treated with ventral rectopexy for external rectal prolapse or symptomatic internal rectal prolapse in 2005 to 2013 were included. Interventions: A questionnaire concerning disease-related symptoms and effect on quality of life was used. Main outcome measures: Defecatory function measured by the Wexner score, the obstructive defecation score, and subjective symptom and quality-of-life evaluation using the visual analog scale were included. The effects of patient-related factors and operative technical details were assessed using multivariate analysis. Results: The questionnaire response rate was 70.7% (330/467 living patients) with a median follow-up time of 44 months. The mean Wexner scores were 7.0 (SD = 6.1) and 6.9 (SD = 5.6), and the mean obstructive defecation scores were 9.7 (SD = 7.6) and 12.3 (SD = 8.0) for patients presenting with external rectal prolapse and internal rectal prolapse. Subjective symptom relief was experienced by 76% and reported more often by patients with external rectal prolapse than with internal rectal prolapse (86% vs 68%; p < 0.001). Complications occurred in 11.4% of patients, and the recurrence rate for rectal prolapse was 7.1%. Limitations: This study was limited by its lack of preoperative functional data and suboptimal questionnaire response rate. Conclusions: Ventral mesh rectopexy effectively treats posterior pelvic floor dysfunction with a low complication rate and an acceptable recurrence rate. Patients with external rectal prolapse benefit more from the operation than those with symptomatic internal rectal prolapse. See Video Abstract at http://links.lww.com/DCR/A479
