Twenty-four hours stay after colorectal surgery: a systematic review

Introduction: The introduction of Enhanced Recovery After Surgery led to increasing twenty-four hours discharge pathways, for example in laparoscopic cholecystectomy and bariatric surgery. However, implementation in colorectal surgery still must set off. This systematic review assesses safety and feasibility of twenty-four hours discharge in colorectal surgery in terms of readmission and complications in current literature. Secondary outcome was identification of factors associated with success of twenty-four hours discharge. Methods: Pubmed and EMBASE databases were searched to identify studies investigating twenty-four hours discharge in colorectal surgery, without restriction of study type. Search strategy included keywords relating to ambulatory management and colorectal surgery. Studies were scored according to MINORS score. Results: Thirteen studies were included in this systematic review, consisting of six prospective and seven retrospective studies. Number of participants of the included prospective studies ranged from 5 to 157. Median success of discharge was 96% in the twenty-four hours discharge group. All prospective studies showed similar readmission and complication rates between twenty-four hours discharge and conventional postoperative management. Factors associated with success of twenty-four hours discharge were low ASA classification, younger age, minimally invasive approach, and relatively shorter operation time. Conclusions: Twenty-four hours discharge in colorectal surgery seems feasible and safe, based on retro- and prospective studies. Careful selection of patients and establishment of a clear and adequate protocol are key items to assure safety and feasibility. Results should be interpreted with caution, due to heterogeneity. To confirm results, an adequately powered prospective randomized study is needed. (AU)

Use of ileostomy versus colostomy as a bridge to surgery in left-sided obstructive colon cancer: retrospective cohort study.

BACKGROUND: Colorectal cancer causes the majority of large bowel obstructions and surgical resection remains the gold standard for curative treatment. There is evidence that a deviating stoma as a bridge to surgery can reduce postoperative mortality rate; however, the optimal stoma type is unclear. The aim of this study was to compare outcomes between ileostomy and colostomy as a bridge to surgery in left-sided obstructive colon cancer. METHODS: This was a national, retrospective population-based cohort study with 75 contributing hospitals. Patients with radiological left-sided obstructive colon cancer between 2009 and 2016, where a deviating stoma was used as a bridge to surgery, were included. Exclusion criteria were palliative treatment intent, perforation at presentation, emergency resection, and multivisceral resection. RESULTS: A total of 321 patients underwent a deviating stoma; 41 (12.7 per cent) ileostomies and 280 (87.2 per cent) colostomies. The ileostomy group had longer length of stay (median 13 (interquartile range (i.q.r.) 10-16) versus 9 (i.q.r. 6-14) days, P = 0.003) and more nutritional support during the bridging interval. Both groups showed similar complication rates in the bridging interval and after primary resection, including anastomotic leakage. Stoma reversal during resection was more common in the colostomy group (9 (22.0 per cent) versus 129 (46.1 per cent) for ileostomy and colostomy respectively, P = 0.006). CONCLUSION: This study demonstrated that patients having a colostomy as a bridge to surgery in left-sided obstructive colon cancer had a shorter length of stay and lower need for nutritional support. No difference in postoperative complications were found.

The Diagnostic Accuracy of Abdominal Computed Tomography in Diagnosing Internal Herniation Following Roux-en-Y Gastric Bypass Surgery: A Systematic Review and Meta-analysis.

OBJECTIVE: To analyze the diagnostic accuracy of abdominal computed tomography (CT) in diagnosing internal herniation (IH) following Rouxen-Y gastric bypass (RYGB) surgery. SUMMARY OF BACKGROUND DATA: IH is one of the most important and challenging complications following RYGB. Therefore, early and adequate diagnosis of IH is necessary. Currently, exploratory surgery is considered the gold standard in diagnosing IH. Although CT scans are frequently being used, the true diagnostic accuracy in diagnosing IH remains unclear. METHODS: PubMed, Embase, and Cochrane databases were systematically searched for relevant articles describing the diagnostic accuracy of abdominal CT in diagnosing IH after RYGB. Data were extracted, recalculated, and pooled to report on the overall diagnostic accuracy of CT in diagnosing IH, and the diagnostic accuracy of specific radiological signs. RESULTS: A total of 20 studies describing 1637 patients were included. seventeen studies provided data regarding the overall diagnostic accuracy: pooled sensitivity of 82.0%, specificity of 84.8%, positive predictive value of 82.7%, and negative predictive value of 85.8% were calculated. Eleven studies reported on specific CT signs and their diagnostic accuracy. The radiological signs with the highest sensitivity were the signs of venous congestion, swirl, and mesenteric oedema (sensitivity of 78.7%, 77.8%, and 67.2%, respectively). CONCLUSIONS: This meta-analysis demonstrates that CT is a reliable imaging modality for the detection of IH. Therefore, abdominal CT imaging should be added to the diagnostic work-up for RYGB patients who present themselves with abdominal pain suggestive of IH to improve patient selection for explorative surgery.

Health-related quality of life in rectal cancer patients undergoing neoadjuvant chemoradiation with delayed surgery versus short-course radiotherapy with immediate surgery: a propensity score-matched cohort study.

BACKGROUND: Neoadjuvant chemoradiation with delayed surgery (CRT-DS) and short-course radiotherapy with immediate surgery (SCRT-IS) are two commonly used treatment strategies for rectal cancer. However, the optimal treatment strategy for patients with intermediate-risk rectal cancer remains a discussion. This study compares quality of life (QOL) between SCRT-IS and CRT-DS from diagnosis until 24 months after treatment. METHODS: In a prospective colorectal cancer cohort, rectal cancer patients with clinical stage T2-3N0-2M0 undergoing SCRT-IS or CRT-DS between 2013 and 2017 were identified. QOL was assessed using EORTC-C30 and EORTC-CR29 questionnaires before the start of neoadjuvant treatment (baseline) and at 3, 6, 12, 18 and 24 months after. Patients were 1:1 matched using propensity sore matching. Between- and within-group differences in QOL domains were analyzed with linear mixed-effects models. Symptoms and sexual interest at 12 and 24 months were compared using logistic regression models. RESULTS: 156 of 225 patients (69%) remained after matching. The CRT-DS group reported poorer emotional functioning at 3, 6, 12, 18 and 24 months (mean difference with SCRT-IS: -9.4, -12.1, -7.3, -8.0 and -7.9 respectively), and poorer global health, physical-, role-, social- and cognitive functioning at 6 months (mean difference with SCRT-IS: -9.1, -9.8, -14.0, -9.2 and -12.6, respectively). Besides emotional functioning, all QOL domains were comparable at 12, 18 and 24 months. Within-group changes showed a significant improvement of emotional functioning after baseline in the SCRT-IS group, whereas only a minor improvement was observed in the CRT-DS group. Symptoms and sexual interest in male patients at 12 and 24 months were comparable between the groups. CONCLUSIONS: In rectal cancer patients, CRT-DS may induce a stronger decline in short-term QOL than SCRT-IS. From 12 months onwards, QOL domains, symptoms and sexual interest in male patients were comparable between the groups. However, emotional functioning remained higher after SCRT-IS than after CRT-DS.

Effect of Neoadjuvant Therapy and Rectal Surgery on Health-related Quality of Life in Patients With Rectal Cancer During the First 2 Years After Diagnosis.

INTRODUCTION: Rectal cancer surgery with neoadjuvant therapy is associated with substantial morbidity. The present study describes the course of quality of life (QOL) in rectal cancer patients in the first 2 years after the start of treatment. PATIENTS AND METHODS: We performed a prospective study within a colorectal cancer cohort including rectal cancer patients who were referred for neoadjuvant chemoradiation or short-course radiotherapy and underwent rectal surgery. QOL was assessed using the European Organization for Research and Treatment of Cancer core questionnaire (EORTC QLQ-C30) and colorectal cancer questionnaire (EORTC QLQ-CR29) before treatment and after 3, 6, 12, 18, and 24 months. The outcomes were compared with the QOL scores from the Dutch general population and stratified by low anterior resection and abdominoperineal resection. Postoperative bowel dysfunction after low anterior resection was measured using the low anterior resection syndrome score. RESULTS: Of the 324 patients, 272 (84%) responded to at least 2 questionnaires and were included in the present study. Compared with pretreatment levels, the strongest decline was observed in physical, role, and social functioning at 3 and 6 months after the start of treatment. Global health and cognitive functioning declined to a lesser extend, and emotional functioning gradually improved over the time. Within 24 months, the QOL scores had recovered toward the pretreatment levels in most patients. Compared with the general population, physical, role, social, and cognitive functioning and symptoms of fatigue and insomnia remained significantly worse in patients on longer-term. After low anterior resection, major bowel dysfunction was reported by 44% to 60% of the patients. Increasing urinary incontinence and severe complaints of impotence were observed in patients who had undergone abdominoperineal resection. CONCLUSION: Rectal cancer treatment is associated with a significant decline in QOL during the first 6 months after the diagnosis. Within 2 years, most patients return toward pretreatment functioning but could still experience poorer functioning and treatment-related symptoms compared with the general population. These findings support shared decision-making and emphasize the need for postoperative supportive care and novel treatment approaches.

The impact of postoperative complications on health-related quality of life in older patients with rectal cancer; a prospective cohort study.

OBJECTIVES: As result of the aging population and increasing rectal cancer incidence, more older patients undergo treatment for rectal cancer. This study compares treatment course, postoperative complications, and quality of life (QOL) between older and younger patients with rectal cancer and evaluates the impact of postoperative complications on QOL in the elderly. MATERIALS AND METHODS: Patients with rectal cancer participating in a prospective colorectal cancer cohort and referred for radiotherapy between 2013 and 2016 were included. QOL was assessed with the cancer questionnaire of the European Organisation for Research and Treatment of Cancer (EORTC QLQ-C30) before treatment and at three, six, and twelve months. Outcomes were compared between older patients (≥70years) and younger patients (<70years) and stratified by presence of postoperative complications. RESULTS: In total, 115 (33%) older patients and 230 (67%) younger patients were included. Compared to younger patients, older patients underwent significantly more often short-course radiation with delayed surgery (6.1% and 19.1% respectively) and less often chemoradiation (62.6% and 39.1% respectively), and were more likely to undergo a Hartmann procedure with permanent stoma (3.5% and 13.0% respectively) instead of sphincter-sparing surgery (43.9% and 29.6% respectively). Postoperative complication rates were similar (38.5% in older patients versus 34.7% in younger patients). Older patients had worse physical functioning at six and twelve months after diagnosis compared to younger patients. Presence of postoperative complications had a significant stronger impact on physical- and role functioning in older patients. CONCLUSION: Older patients undergo more often a tailored treatment approach for rectal cancer than younger patients. With this tailored approach, similar postoperative complication rates and QOL are achieved. However, postoperative complications have a larger negative impact on physical- and role functioning in older patients which indicates a need for better prediction of postoperative complications in the elderly.

Late development of pancreas necrosis during acute pancreatitis: an underestimated phenomenon associated with high morbidity and mortality.

OBJECTIVE: The purpose of this study is to assess the prognostic significance of late parenchymal pancreas necrosis as observed on serial contrast-enhanced computed tomographic (CT) scan. METHODS: Eighty-four patients with acute necrotizing pancreatitis were included. All initial CT scans were examined on complete contrast enhancement of the pancreas parenchyma (viable pancreas) or incomplete enhancement indicating parenchymal necrosis of the pancreas (PN). Secondly, all serial CT scans were evaluated to investigate whether late PN occurred in the group with a viable pancreas on initial CT scan. Characteristics of this group were evaluated. RESULTS: Thirteen patients showed signs of PN on initial CT scan. Late necrosis occurred in 5 patients. The average hospital stay in this subgroup was 46.7 days; complication rate, 100%; and mortality, 40%. A significant difference in hospital stay (average of 45.1 days vs 24.3 days; P = 0.003), complication rate (72% vs 33%; P = 0.006), and mortality (28% vs 6%; P = 0.019) was found when the group with eventual PN was compared with the group with no signs of PN (on initial and serial CT). CONCLUSIONS: This study shows a significant increase in hospital stay, complication rate, and mortality when eventual PN is shown on CT scan. Patients with late PN especially have a poor prognosis.
