Background

We conducted a retrospective cohort study to compare the outcomes of laparoscopic colon resection (LCR) with open colon resection (OCR) for complicated diverticular disease (CDD) during emergent hospital admission.

Methods

Charts from all patients undergoing colon resection for CDD during emergent hospital admission at a single academic institution were reviewed. The primary outcomes were overall 30-day postoperative morbidity and mortality.

Results

From 2000 to 2010, 125 cases were retrieved (49 LCR and 86 OCR). Conversion rate was 5.1%. Overall morbidity significantly decreased with laparoscopic surgery compared with OCR. No mortality occurred with LCR. Prolonged ileus was less frequent (12.8% vs 32.6%; P = .02), time to oral intake shorter (3 vs 6 days; P < .01), and LOS shorter (5 vs 8 days; P = .05) for LCR.

Conclusions

In our series, in the patients selected, LCR for CDD during emergent hospital admission appears to be a safe procedure associated with decreased morbidity, time to oral intake, and LOS compared with OCR.  相似文献

Turnbull and Cutait described abdominoperineal pull-through followed by delayed coloanal anastomosis (DCA) in 1961. DCA could reduce anastomotic leaks, pelvic morbidity and use of stomas. Strong evidence about its clinical benefits is still lacking. This systematic review examined the clinical outcomes of DCA for the treatment of malignant or benign colorectal conditions. A systematic search of electronic medical databases was conducted. Two independent reviewers selected studies, extracted data and assessed risk of bias. The primary outcome was pelvic morbidity (anastomotic leak, pelvic abscess or sepsis, use of stoma). Fecal continence and survival data were also analyzed. From 1,251 citations, we included seven observational studies including 1,124 patients. All included studies were considered at high risk of bias. Two studies comparing DCA with immediate anastomosis reported a significant decrease in anastomotic leak, and pelvic abscess or sepsis. Low rates of pelvic morbidity were reported in the other five studies: anastomotic leak 0–7 %, pelvic abscess 0–11.8 % and pelvic sepsis 6.8–10 %. Rates of permanent stoma after DCA were low in six studies (1–6 %), with one study reporting an incidence of 25 %. Fecal continence was reported as satisfying in all studies. No differences were observed in a comparative setting. Survival data were reported in four studies. Clinical heterogeneity and methodological issues precluded meta-analysis. Based on retrospective evidence, DCA offers a low rate of anastomotic leak, pelvic morbidity and use of stoma, with reasonable fecal continence. Results are encouraging, but prospective studies are needed for comparison with standard of care.  相似文献

Background

Guidelines recommend 28 days venous thromboembolism (VTE) prophylaxis with low-molecular-weight heparin (LMWH) following major abdominal surgery for cancer. Overall adherence with these recommendations is poor, but little is known about feasibility and tolerability from a patient perspective.

Methods

An institution-wide policy for routine administration of 28 days of post-operative LMWH following major hepatic or pancreatic resection for cancer was implemented in April 2013. Patients having surgery from July 2013 to June 2015 were approached to participate in an interview examining adherence and experience with extended duration LMWH.

Results

There were 100 patients included, with 81.4 % reporting perfect adherence with the regimen. The most frequent reasons for non-adherence were that a healthcare provider stopped the regimen or because of poor experience with injections. Most patients were able to correctly recall the reason for being prescribed LMWH (82.6 %), and 78.4 % of patients performed all injections themselves. Over half the patients (55.7 %) did not find the injections bothersome.

Conclusion

Patients reported high adherence and a manageable experience with post-operative extended-duration LMWH in an ambulatory setting following liver or pancreas resection. These findings suggest that patient adherence is not a major contributor to poor compliance with VTE prophylaxis guidelines.

Background

Turnbull–Cutait abdominoperineal pull-through followed by delayed coloanal anastomosis (DCA) was first described in 1961. Studies have described its use for challenging colorectal conditions. We reviewed our experience with Turnbull–Cutait DCA as a salvage procedure for complex failure of colorectal anastomosis.

Methods

We performed a retrospective cohort study from October 2010 to September 2011, with analysis of postoperative morbidity and mortality.

Results

Seven DCAs were performed for anastomotic complications (3 chronic leaks, 2 rectovaginal fistulas, 1 colovesical fistula, 1 colonic ischemia) following surgery for rectal cancer. Six patients had a diverting ileostomy constructed as part of previous treatment for anastomotic complications before the salvage procedure. No anastomotic leaks were observed. All procedures but 1 were completed successfully. One patient who underwent DCA subsequently required an abdominoperineal resection and a permanent colostomy for postoperative extensive colonic ischemia. No 30-day mortality occurred.

Conclusion

Salvage Turnbull–Cutait DCA appears to be a safe procedure and could be offered to patients with complex anastomotic complications. This procedure could be added to the surgeon’s armamentarium as an alternative to the creation of a permanent stoma.  相似文献

Optimal interprofessional communication (IPC) is broadly viewed as a prerequisite to providing quality patient care. In this study, we explored the enablers and barriers to IPC between surgical trainees and ward nurses with a view towards improving IPC and the quality of surgical patient care. We conducted an ethnography in two academic centres in Canada totalling 126 hours of observations and 32 semi-structured interviews with trainees and nurses. Our findings revealed constraints on IPC between trainees and nurses derived from contested meanings of space and time. Trainees experienced the contested spatial boundaries of the surgical ward when they perceived nurses to project a sense of territoriality. Nurses expressed difficulty getting trainees to respond and attend to pages from the ward, and to have a poor understanding of the nurses’ role. Contestations over time spent in training and patient care were found in trainee–nurse interactions, wherein trainees perceived seasoned nurses to devalue their clinical knowledge on the ward. Nurses viewed the limited time that trainees spent in clinical rotation in the ward as adversely affecting communication. This study underscores that challenges to enhancing IPC at academic health centres are rooted in team and professional cultures. Efforts to improve IPC should therefore: identify and target the social and cultural dimensions of healthcare team member relations; recognise how power is deployed and experienced in ways that negatively impact IPC; and enhance an understanding and appreciation in the temporal and spatial dimensions of IPC.  相似文献
