RESUMEN

INTRODUCTION: The population in developed countries is getting older and with advancing age comes increasing co-morbidity and demand on health care services. The use of home parenteral nutrition (HPN) is also increasing in the UK and elsewhere. Age and co-morbidity need to be taken into consideration when HPN is contemplated because of the significant associated economic burden and clinical risk. However, there are minimal data on HPN outcomes specific to the elderly. METHOD: We performed an observational study of a prospectively maintained database of patients dependent on HPN managed at a national U.K. referral centre. Data were collected on the 31st March 2018. Charlson index was used to assess co-morbidity. Data included demographics, HPN requirements, underlying disease aetiology, mechanism of intestinal failure, and whether the patient, carer or home care nurses administered the PN. The main outcome was the occurrence of at least one catheter-related blood stream infection (CRBSI) during HPN, with putative predictors of CRBSI assessed by uni- and multi-variable logistic regression. RESULTS: Two hundred and seventy-seven patients were included in this study, 62% were female and the overall mean age of the entire cohort was 58 years (range 20-93). The mean duration of HPN was 1778 days (range 45-12,832). One hundred patients were aged 65 years or older. Patients aged 65 years or older had a higher Charlson index (1.8 vs 1.1, p = <0.0001), were more likely to require a home care nurse to administer PN (p = 0.01), and had the lowest risk of CRBSI (25% vs 39%; p = 0.01). Home care nurse administration was associated with the lowest risk of CRBSI, followed by carer and self-administration (P = 0.001). In multivariable analysis, duration of HPN and CVC care provider were the only independent predictors of CRBSI occurrence. There was no significant difference in unplanned intestinal failure-related hospital admissions between those under or above 65 years of age (p = 0.08). CONCLUSIONS: HPN can be safely used in patients over the age of 65, even with increased co-morbidity. In this large cohort study, increasing age was found to be protective against CRBSI. CVC care provider was an independent predictor of CRBSI, while age and co-morbidity were not, suggesting that the use of home care nurses for PN administration is the principal reason for the low CRBSI rate in the elderly. Hence, older age should not be seen as a contra-indication for HPN, but increased healthcare resource may be required as those aged over 65 are more likely to require nursing assistance for CVC care.

RESUMEN

BACKGROUND: The use of home parenteral nutrition (HPN) for palliative indications is increasing internationally and is the leading indication in some countries. Discharge on HPN can be complex in metabolically unstable patients and requires intestinal failure expertise. METHODS: Between 2012 and 2018, we performed a retrospective analysis aiming to assess the impact of a novel remote discharge pathway for palliative HPN patients. This was evaluated using a quality improvement approach. RESULTS: One hundred and twenty-five patients with active malignancy [mean (range) age 58 (25-80) years] were referred to the intestinal failure unit (IFU) for remote discharge. Of 82 patients were discharged from the oncology Centre on HPN using the pathway. The remaining 43 patients either declined HPN or the Oncology team felt that the patient became too unwell for HPN or died prior to discharge. There was an increase in patients referred for remote discharge from 13 in 2012 to 43 in 2017. The mean number of days between receipt of referral by the IFU to discharge on HPN from the oncology centre reduced from 29.4 days to 10.1 days. Following remote discharge, the mean number of days on HPN was 215.9 days. Catheter-related blood stream infection rates in this cohort were very low at 0.169 per 1000 catheter days. CONCLUSIONS: This is the first study to demonstrate the remote safe, effective and rapid discharge of patients requiring palliative HPN between two hospital sites. This allows patients with a short prognosis more time in their desired location.

RESUMEN

INTRODUCTION: The management of intestinal failure (IF) requires safe and sustained delivery of parenteral nutrition (PN). The long-term maintenance of central venous catheter (CVC) access is therefore vital, with meticulous catheter care and salvage of infected CVCs being of prime importance. CVC-related infection and loss of intravenous access are important causes of morbidity and mortality in IF. Avoidance, prompt recognition and appropriate management of CVC-related infections are crucial components of IF care. However, there are few, if any, data on the occurrence of CVC-related infections in patients with acute, type 2, IF managed on a dedicated IF unit and no data on the salvage outcomes of infected CVCs in this group of patients. METHODS: This is a retrospective observational study conducted between January 2011 and July 2017. All patients with acute, type 2 IF newly admitted to a national U.K. IF unit (IFU) during these dates were included. All patients admitted to the unit with a CVC in place underwent immediate 'screening' paired central and peripheral blood cultures on arrival before the CVC was used for any infusate. A prospectively maintained database was used to record all confirmed catheter-related blood stream infections (BSI)/colonisations, demographic and clinical data. Diagnosis of catheter-related BSI/colonisation was based on quantitative and qualitative analysis of paired central and peripheral blood cultures. A standardized 10-14-day catheter salvage treatment protocol involving antibiotic and urokinase CVC locks and systemic antibiotic administration was used to salvage any infected or colonised CVCs, as appropriate. The CVC was not used for PN until successful salvage had been confirmed by negative blood cultures drawn 48 h after antibiotic completion. The development of a subsequent catheter-related BSI was recorded for all patients, both during the remaining in-patient stay on the IFU and after discharge home on PN. RESULTS: Of the 509 patients with type 2 IF admitted to the IFU during the study period, 341 (54% female; mean age 54.6 (range 16-86 years)) had an indwelling CVC that had been placed in the referring hospital. Surgical complications and mesenteric ischaemia were the most common underlying disease aetiologies. Sixty-five of 341 (19.1%) patients had an infected/colonised CVC on the initial screening set of blood cultures. A successful CVC salvage rate of 91% was achieved in this cohort after antibiotic therapy. The subsequent in-patient catheter-related BSI rate for those admitted with a CVC (n = 341) on the IFU was 0.042 per 1000 catheter days, over a total of 23,548 in-patient catheter days. Two hundred and seventy nine of 341 patients were discharged on home PN (HPN); with a subsequent catheter-related BSI rate on HPN of 0.22 per 1000 catheter days (mean duration of HPN = 778 catheter days (range:)) over a follow-up period of 216,944 out-patient catheter days. There was no increased risk of HPN-related catheter-related BSI (p = 0.09) or mortality (p = 0.4) in those admitted with an infected CVC. CONCLUSION: This is the first study to report catheter-related BSI/colonisation rates and salvage outcomes in patients with type 2 IF newly admitted to a dedicated IF Unit. We report that nearly one-fifth of all patients were referred with evidence of a catheter related BSI/colonisation; despite this, successful catheter salvage is possible and, with stringent CVC care, an extremely low subsequent catheter related BSI rates can be achieved and maintained during in-patient stay on a dedicated IF Unit and after discharge on HPN. These data provide novel evidence to support ESPEN recommendations that patients with type 2 IF are managed on a dedicated IF Unit.

RESUMEN

INTRODUCTION: Short bowel syndrome (SBS) is a leading cause of intestinal failure (IF). Home parenteral nutrition (HPN) remains the standard treatment, with small intestinal transplantation reserved for cases with severe complications to HPN. There have recently been significant developments in growth factor therapy. We aimed to develop a greater contemporary understanding of our SBS-IF subset. METHOD: We performed a retrospective observational study of a prospectively maintained HPN audit database in October 2017. Intestinal anatomical details and parenteral requirements were recorded. Each case was assessed for eligibility for growth factor therapy using recently published trials. RESULTS: Of 273 patients receiving HPN, 152 (55.7%) had type three IF as a result of SBS (SBS-IF), with a mean duration of HPN of 61 months (range 4-416). Mean length of small intestine was 98 cm. Furthermore, 114 (41.8%) patients had an end jejunostomy (SBS-J), 18 (6.6%) had an end ileostomy, and 7.3% of patients had all or part of the colon-in-continuity. Crohn's disease was the most common underlying pathology. Univariate analysis for the whole HPN cohort demonstrated SBS-IF and a longer duration of HPN to be associated with higher PN energy requirements, p ≤ 0.0001. Of all, 73 (48%) patients with SBS-IF were deemed suitable for GLP-2 analogue therapy, with co-morbidity being the most frequent cause of non-suitability (29.1%). CONCLUSION: We describe a large U.K. HPN cohort using ESPEN pathophysiological and clinical severity classification. The majority of patients with SBS-IF had a jejunostomy and relatively few had colon-in-continuity. Co-morbidity is the most common contra-indication to GLP-2 analogue therapy. CLINICAL RELEVANCY: GLP-2 analogues are emerging as an important treatment for patients with short bowel syndrome. Our study explores patient suitability in a large HPN cohort managed in a national IF centre. Furthermore, the international variation in the pathophysiology of SBS-IF varies significantly, which can have a bearing on PN requirements and outcomes when GLP-2 analogues are used.

RESUMEN

BACKGROUND: This is the fourth updated Enhanced Recovery After Surgery (ERAS®) Society guideline presenting a consensus for optimal perioperative care in colorectal surgery and providing graded recommendations for each ERAS item within the ERAS® protocol. METHODS: A wide database search on English literature publications was performed. Studies on each item within the protocol were selected with particular attention paid to meta-analyses, randomised controlled trials and large prospective cohorts and examined, reviewed and graded according to Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. RESULTS: All recommendations on ERAS® protocol items are based on best available evidence; good-quality trials; meta-analyses of good-quality trials; or large cohort studies. The level of evidence for the use of each item is presented accordingly. CONCLUSIONS: The evidence base and recommendation for items within the multimodal perioperative care pathway are presented by the ERAS® Society in this comprehensive consensus review.

RESUMEN

BACKGROUND: Increasing evidence indicates that combined mechanical and oral antibiotic bowel preparation reduces the infectious complications of colorectal surgery. Anecdotal evidence suggests the combination is rarely used in the UK and Europe. AIM: To establish colorectal surgeons' current use and awareness of the benefits of such bowel preparation, and to identify decision-making influences surrounding preoperative bowel preparation. METHOD: An electronic survey was emailed to all members of the Association of Coloproctology of Great Britain and Ireland, and promoted via Twitter. FINDINGS: A total of 495 respondents completed the survey: 413 (83.2%) UK, 39 (7.9%) other European, 43 (8.7%) non-European. Respondents used oral antibiotics for 12-20% of cases. Mechanical bowel preparation (MBP), phosphate enema, and no preparation, respectively, ranged between 9 and 80%. Combined MBP and oral antibiotic bowel preparation ranged between 5.5 and 18.6%. Fifty-three percent (260/495) agreed that combined mechanical and oral antibiotic bowel preparation reduces surgical site infection; 32% (157/495) agreed that the combination reduces risk of anastomotic leak. Kappa statistics between 0.06 and 0.27 indicate considerable incongruity between surgeons' awareness of the literature, and day-to-day practice. Twenty-four percent (96/495) believed MBP to be incompatible with enhanced recovery after surgery (ERAS); 41% (204/495) believed that MBP delays return to normal intestinal function. CONCLUSIONS: Few UK and European colorectal surgeons use mechanical and oral antibiotic bowel preparation, despite evidence of its efficacy in reducing infectious complications. The influence of ERAS pathways and UK and European guidelines may explain this. In contradiction to the UK and Europe, North American guidelines recommend incorporating combined mechanical and oral antibiotic bowel preparation into ERAS programmes. This study suggests that future UK and European guidelines incorporate combined mechanical and oral antibiotic bowel preparation into the ERAS pathway.

RESUMEN

AIM: There is a requirement of an expansive and up to date review of surgical management of inflammatory bowel disease (IBD) that can dovetail with the medical guidelines produced by the British Society of Gastroenterology. METHODS: Surgeons who are members of the ACPGBI with a recognised interest in IBD were invited to contribute various sections of the guidelines. They were directed to produce a procedure based document using literature searches that were systematic, comprehensible, transparent and reproducible. Levels of evidence were graded. An editorial board was convened to ensure consistency of style, presentation and quality. Each author was asked to provide a set of recommendations which were evidence based and unambiguous. These recommendations were submitted to the whole guideline group and scored. They were then refined and submitted to a second vote. Only those that achieved >80% consensus at level 5 (strongly agree) or level 4 (agree) after 2 votes were included in the guidelines. RESULTS: All aspects of surgical care for IBD have been included along with 157 recommendations for management. CONCLUSION: These guidelines provide an up to date and evidence based summary of the current surgical knowledge in the management of IBD and will serve as a useful practical text for clinicians performing this type of surgery.

RESUMEN

BACKGROUND & AIMS: Prevention of catheter related blood stream infections (CRBSI) and salvage of infected central venous catheters (CVC) are vital to maintaining long term venous access in patients needing home parenteral nutrition (HPN). It remains unclear as to whether patients are best trained for catheter care at home or in hospital or whether CRBSIs are lower if the patient self-cares for the CVC. Furthermore, there is minimal data on the longer term outcome following salvage of infected catheter and limited consensus on agreed protocols for catheter salvage. METHOD: We conducted a retrospective 5-year evaluation of CRBSI occurrence and CVC salvage outcomes in adult patients requiring HPN managed at a national UK Intestinal Failure Unit from 2012 to 2016. Prior to 2012, patients were primarily trained to administer PN in hospital; thereafter, patients underwent training at home. RESULTS: A total of 134 CRBSI were recorded in 92 patients (62 patients with a single CRBSI and 30 patients with more than 1 CRBSI) in a cohort of 559 HPN patients, with a total of 1163 HPN years. The overall CRBSI rate was 0.31 per 1000 catheter days. CNS were the most common isolates (41/134 (30.5%)), followed by polymicrobial infections (14/134 (10.4%)), Klebsiella spp. (16/134 (11.9%)) and methicillin - sensitive Staphylococcus aureus (MSSA) 5/134 ((3.7%)). Salvage was not attempted in 34 cases due to methicillin - resistant (MRSA) infection (1/34), fungal infection (13/34) or clinical instability due to sepsis (20/34). Of the 100 cases where salvage was attempted, 67% were successful. 82.8% of CNS salvage attempts were successful; there was no difference in salvage rates between CNS CRBSIs salvaged with a 10-day (22/26) or 14-day protocol (7/9) (p = 0.4). CRBSI rate, in those cared for by trained home care nurses was the lowest at 0.270 (self care: 0.342 and non-medical carer (e.g. family member): 0.320) (p = 0.03). CONCLUSION: We previously reported a sustained very low CRBSI rate in a large cohort of HPN patients in a national unit; we now further report that this is not influenced by training patients at home rather than in hospital but is influenced by the individual managing the catheter at home. CNS remains the primary cause of CRBSIs and can be successfully salvaged with a reduced duration of antibiotic therapy compared to our previous experience.

RESUMEN

INTRODUCTION While clinical guidelines stress the importance of the judicious perioperative intravenous fluid administration, data show that adherence to these protocols is poor. The reasons have not been identified. We therefore audited the magnitude and indications of fluid and electrolyte administration in a teaching hospital. We hypothesised that epidural analgesia is associated with excessive fluid therapy. MATERIALS AND METHODS Intravenous fluid and electrolyte administration during the day of surgery and the subsequent 2 days in consecutive patients undergoing elective gastrointestinal surgery between November 2013 and May 2014 were retrospectively audited. Timing, volumes and indications were recorded. RESULTS One hundred patients undergoing elective gastrointestinal resection were studied. Patients received 9030 ml ± 2860 ml (mean ± standard deviation) intravenous fluids containing a total of 1180 ml ± 420 mmol sodium and resulting in a cumulative fluid balance of +5120 ml ± 2510 ml; 44% ± 14% of total volumes were given in theatre. Nearly all fluid was given for maintenance, 100% (96-100%, interquartile range), with 17 patients only receiving replacement or resuscitation. Independent predictors of increased volumes included open surgery, upper gastrointestinal surgery, increased duration and epidural analgesia but not body weight. Postoperative fluid volume was the only independent predictor of postoperative complication grade (P = 0.0044). CONCLUSIONS Despite published guidelines, perioperative fluid and electrolyte administration were excessive and were associated with postoperative morbidity. Substantial volumes were administered in theatre. Nearly all administration was for maintenance, yet patients received approximately five times the amount of sodium required. Epidural analgesia was an independent predictor of fluid volumes but body weight was not.

RESUMEN

BACKGROUND: Current guidance on the management of sepsis often applies to infection originating from abdominal or pelvic sources, which presents specific challenges and opportunities for efficient and rapid source control. Advances made in the past decade are presented in this article. METHODS: A qualitative systematic review was undertaken by searching standard literature databases for English-language studies presenting original data on the clinical management of abdominal and pelvic complex infection in adults over the past 10 years. High-quality studies relevant to five topical themes that emerged during review were included. RESULTS: Important developments and promising preliminary work are presented, relating to: imaging and other diagnostic modalities; antimicrobial therapy and the importance of antimicrobial stewardship; the particular challenges posed by fungal sepsis; novel techniques in percutaneous and endoscopic source control; and current issues relating to surgical source control and managing the abdominal wound. Logistical challenges relating to rapid access to cross-sectional imaging, interventional radiology and operating theatres need to be addressed so that international benchmarks can be met. CONCLUSION: Important advances have been made in the diagnosis, non-operative and surgical control of abdominal or pelvic sources, which may improve outcomes in the future. Important areas for continued research include the diagnosis and therapy of fungal infection and the challenges of managing the open abdomen.

RESUMEN

BACKGROUND: Sepsis is associated with profound alterations in protein metabolism. The unpredictable time course of sepsis and the multiplicity of confounding factors prevent studies of temporal relations between the onset of endocrine and proinflammatory cytokine responses and the onset of protein catabolism. This study aimed to determine the time course of whole-body protein catabolism, and relate it to the endocrine, metabolic and cytokine responses in a human endotoxaemia model of early sepsis. METHODS: Six healthy male volunteers were studied twice in random order, before and for 600 min after administration of either an intravenous bolus of Escherichia coli lipopolysaccharide (LPS) or sterile saline. Whole-body protein synthesis, breakdown and net protein breakdown were measured by amino acid tracer infusion, and related to changes in plasma levels of growth hormone, glucagon, cortisol, insulin-like growth factor (IGF) 1, tumour necrosis factor (TNF) α and interleukin (IL) 6. RESULTS: Protein synthesis, breakdown and net protein breakdown increased and peaked 120 min after LPS administration (P < 0·001), the alterations persisting for up to 480 min. These peaks coincided with peaks in plasma growth hormone, TNF-α and IL-6 concentrations (P = 0·049, P < 0·001 and P < 0·001 for LPS versus saline), whereas plasma cortisol concentration peaked later. No alterations in plasma insulin or glucagon concentrations, or in the IGF axis were observed during the period of abnormalities of protein metabolism. CONCLUSION: LPS administration induced an early protein catabolic response in young men and this coincided with changes in plasma growth hormone, TNF-α and IL-6 concentrations, rather than changes in cortisol, glucagon, insulin or the IGF axis. Surgical relevance Sepsis in surgical patients is common and remains associated with substantial mortality. Although sepsis is a heterogeneous condition and its pathophysiology therefore difficult to study, a universal and profound clinical problem is protein catabolism not responsive to nutritional support. Human experimental endotoxaemia is a promising model of clinical sepsis that can be used to elucidate underlying pathophysiology and explore novel therapeutic approaches. This study demonstrates that human experimental endotoxaemia replicates the changes in whole-body protein turnover seen in clinical sepsis. Frequent measurements allowed identification of tumour necrosis factor (TNF) α, interleukin (IL) 6 and growth hormone as putative mediators. Human experimental endotoxaemia is a valid model for further study of mechanisms and putative therapies of catabolism associated with sepsis. In particular, effects of TNF-α and IL-6 blockade should be evaluated.

RESUMEN

The standardisation of the surgical management of rectal cancer has been facilitated by adoption of an anatomic surgical nomenclature. Thus, "total mesorectal excision" substituted "anterior resection" or "proctosigmoidectomy" and implies resection of both rectum and mesorectum. Similar trends towards standardisation of colonic surgery are ongoing, yet there remains a heterogeneity of terminology utilised (eg, "right hemicolectomy", "ileocolic resection", and "total mesocolic excision"). Recent descriptions of mesocolic anatomy provide an opportunity to standardise colonic resection according to a more precise and informative anatomic nomenclature. This article aims to firstly emphasise the central importance of the mesocolon and from this propose a related nomenclature for resectional colonic surgery. Introduction of a standardised nomenclature for colonic resection is a necessary step towards standardisation of colonic surgery in general.

RESUMEN

BACKGROUND: Goal-directed fluid therapy (GDFT) has been compared with liberal fluid administration in non-optimized perioperative settings. It is not known whether GDFT is of value within an enhanced recovery protocol incorporating fluid restriction. This study evaluated GDFT under these circumstances in patients undergoing elective colectomy. METHODS: Patients undergoing elective laparoscopic or open colectomy within an established enhanced recovery protocol (including fluid restriction) were randomized to GDFT or no GDFT. Bowel preparation was permitted for left colonic operations at the surgeon's discretion. Exclusion criteria included rectal tumours and stoma formation. The primary outcome was a patient-reported surgical recovery score (SRS). Secondary endpoints included clinical outcomes and physiological measures of recovery. RESULTS: Eighty-five patients were randomized, and there were 37 patients in each group for analysis. Nine patients in the GDFT and four in the fluid restriction group received oral bowel preparation for either anterior resection (12) or subtotal colectomy (1). Patients in the GDFT group received more colloid during surgery (mean 591 versus 297 ml; P = 0·012) and had superior cardiac indices (mean corrected flow time 374 versus 355 ms; P = 0·018). However, no differences were observed between the GDFT and fluid restriction groups with regard to surgical recovery (mean SRS after 7 days 47 versus 46 respectively; P = 0·853), other secondary outcomes (mean aldosterone/renin ratio 9 versus 8; P = 0·898), total postoperative fluid (median 3750 versus 2400 ml; P = 0·604), length of hospital stay (median 6 versus 5 days; P = 0·570) or number of patients with complications (26 versus 27; P = 1·000). CONCLUSION: GDFT did not provide clinical benefit in patients undergoing elective colectomy within a protocol incorporating fluid restriction.

RESUMEN

BACKGROUND: This review aims to present a consensus for optimal perioperative care in colonic surgery and to provide graded recommendations for items for an evidenced-based enhanced perioperative protocol. METHODS: Studies were selected with particular attention paid to meta-analyses, randomised controlled trials and large prospective cohorts. For each item of the perioperative treatment pathway, available English-language literature was examined, reviewed and graded. A consensus recommendation was reached after critical appraisal of the literature by the group. RESULTS: For most of the protocol items, recommendations are based on good-quality trials or meta-analyses of good-quality trials (quality of evidence and recommendations according to the GRADE system). CONCLUSIONS: Based on the evidence available for each item of the multimodal perioperative-care pathway, the Enhanced Recovery After Surgery (ERAS) Society, International Association for Surgical Metabolism and Nutrition (IASMEN) and European Society for Clinical Nutrition and Metabolism (ESPEN) present a comprehensive evidence-based consensus review of perioperative care for colonic surgery.

RESUMEN

BACKGROUND: This review aims to present a consensus for optimal perioperative care in rectal/pelvic surgery, and to provide graded recommendations for items for an evidenced-based enhanced recovery protocol. METHODS: Studies were selected with particular attention paid to meta-analyses, randomized controlled trials and large prospective cohorts. For each item of the perioperative treatment pathway, available English-language literature was examined, reviewed and graded. A consensus recommendation was reached after critical appraisal of the literature by the group. RESULTS: For most of the protocol items, recommendations are based on good-quality trials or meta-analyses of good-quality trials (evidence grade: high or moderate). CONCLUSIONS: Based on the evidence available for each item of the multimodal perioperative care pathway, the Enhanced Recovery After Surgery (ERAS) Society, European Society for Clinical Nutrition and Metabolism (ESPEN) and International Association for Surgical Metabolism and Nutrition (IASMEN) present a comprehensive evidence-based consensus review of perioperative care for rectal surgery.

RESUMEN

BACKGROUND: Intraoperative cholangiography (IOC) is used to detect choledocholithiasis and identify or prevent bile duct injury. The aim of this study was systematically to review the randomized clinical trials of IOC for these two indications. METHODS: MEDLINE, Embase, the Cochrane Library, clinicaltrials.gov and the World Health Organization database of clinical trials were searched systematically (January 1980 to February 2011) to identify trials. Two authors performed the literature search and extracted data independently. Primary endpoints were bile duct injury and retained common bile duct (CBD) stones diagnosed at any stage after surgery. Preliminary meta-analysis was undertaken, but the trials were too methodologically heterogeneous and the outcome events too infrequent to allow meaningful meta-analysis. RESULTS: Eight randomized trials were identified including 1715 patients. Six trials assessed the value of routine IOC in patients at low risk of choledocholithiasis. Two trials randomized all patients (including those at high risk) to routine or selective IOC. Two cases of major bile duct injury were reported, and 13 of retained CBD stones. No trial demonstrated a benefit in detecting CBD stones. IOC added a mean of 16 min to the total operating time. CONCLUSION: There is no robust evidence to support or abandon the use of IOC to prevent retained CBD stones or bile duct injury. Level 1 evidence for IOC is of poor to moderate quality. None of the trials, alone or in combination, was sufficiently powered to demonstrate a benefit of IOC. Further small trials cannot be recommended.

RESUMEN

AIM: Recent surveys in Europe and North America have demonstrated significant challenges in the implementation of evidence-based surgical practice. METHOD: A survey of New Zealand and Australian colorectal surgeons was conducted to help understand current practice and perceived barriers to interventions in this region. Questions were based around elective colorectal resection care. RESULTS: There were 152 eligible participants identified. Over a 60-day period, 82 (54%) surgeons responded but only 76 (50%) of the questionnaires were complete; they were used for data analysis. The majority of surgeons indicated a preference for laparoscopic techniques. Barriers to laparoscopy include lack of operating time, lack of adequate training and institutional pressures. Only 28 (37%) indicated that they cared for patients in a formalized enhanced recovery programme (ERAS). Barriers to implementing ERAS included lack of support from institutions and other specialities. Routine oral 'mechanical' bowel preparation for colon and rectal resection was preferred by 28% and 63%, respectively. Drainage after routine colon and rectal resection was not used by 62 (83%) and 39 (53%). Prophylactic nasogastric intubation afterwards was not used by 66 (87%) responders. The preferred mode of analgesia was patient-controlled opioid analgesia (PCA) for 52%. A 'restrictive' intravenous fluid therapy was preferred by 34 (49%) while 33 (48%) preferred no fluid restriction. A prolonged 'nil by mouth' status was preferred by 28%. CONCLUSION: There appears to be a high rate of evidence in agreement with some interventions but not others. The systemic barriers to implementing evidence-based perioperative care need attention.

RESUMEN

OBJECTIVE: To evaluate short-term outcomes after construction of synchronous colonic anastomoses without fecal diversion. METHOD: Using a prospective procedural database, all adult general surgery patients who underwent two synchronous segmental colon resections and anastomoses without ostomy at our institution from 1992-2007 were identified. Demographics, operative techniques, and 30-day outcomes are reported. Results are number (percent) of patients or median (interquartile range). RESULTS: Over 15 years, 69 patients underwent double colonic anastomoses [40 males, age 63 (45-76) years, BMI 25.3 (22.9-28.7) kg/m(2)]. Multiple colonic anastomoses were performed in one of every 201 colectomies during the study period (0.5%). The operation was an emergency in two (3%) cases; most cases were clean-contaminated 56 (81%). Ten (17%) cases were laparoscopic-assisted with a 44% conversion rate. Length of stay was seven (5-10) days. Overall 30-day morbidity was 36% including nine (13%) surgical site infections, two (2.9%) intra-abdominal abscesses requiring percutaneous drainage, and one (1.4%) wound dehiscence. There were no anastomotic leaks or fistulas, and two patients (2.9%) died within 30 days from pulmonary sepsis and complications from a distal anastomotic hemorrhage, respectively. CONCLUSIONS: Synchronous colon anastomoses without fecal diversion do not appear to be associated with an increased risk of complications and can be safely constructed in selected patients.
