Postoperative nutrition in the setting of enhanced recovery programmes

Patients undergoing major surgery for gastrointestinal cancer are at high risk of developing or worsening malnutrition and sarcopenia. In malnourished patients, preoperative nutritional support may not be sufficient and so postoperative support is advised. This narrative review addresses several aspects of postoperative nutritional care in the setting of enhanced recovery programmes. Early oral feeding, therapeutic diet, oral nutritional supplements, immunonutrition, and probiotics are discussed. When postoperative intake is insufficient, nutritional support favouring the enteral route is recommended. Whether this approach should use a nasojejunal tube or jejunostomy is still a matter of debate. In the setting of enhanced recovery programmes with early discharge, nutritional follow-up and care should be continued beyond the short time in hospital. In enhanced recovery programmes, the main specific aspects of nutrition are patient education, early oral intake, and post-discharge care. The other aspects do not differ from conventional care.

Is a care pathway for enhanced recovery after colorectal surgery environmentally responsible?

INTRODUCTION

Above and beyond the environmentally responsible operating theater, the environmental impact of the pathways of surgically treated patients seems essential but has seldom been considered in the literature. On a parallel track, enhanced recovery programmes (ERP) programs are presently deemed a standard of care. The objective of this review is to determine the carbon footprint of the ERP approach in colorectal surgery.

METHOD

This a narrative review based on articles referenced in PubMed. Our search was centered on the environmental impact of an ERP in the context of colorectal surgery. A number of measures included in the national and international guidelines were studied. We utilized the terms "carbon footprint", "sustainability", "energy cost", "environmental footprint", "life cycle assessment" AND a key word for each subject found in the ERP recommendations.

RESULTS

Most ERP measures in the context of colorectal surgery are factually or intuitively virtuous from an ecological standpoint. With a 3-day reduction in average hospital stay resulting from ERP, the program permits a reduction of at least 375kg CO2e/patient (Appendices 1 and 2). The most substantial part of this reduction is achieved during the perioperative period. While some measures, such as short fasting, are ecologically neutral, others (treatment of comorbidities, smoking cessation, hypothermia prevention, antibiotic prophylaxis, laparoscopy, absence of drains or probes, thromboprophylaxis, early feeding and mobilization…) lead to fewer postoperative complications, and can consequently be considered as environmentally responsible. Conversely, other measures, one example being robotic surgery, leave a substantial carbon footprint.

CONCLUSION

ERP is congruent with two pillars of sustainable development: the social pillar (improved patient recovery, and better caregiver working conditions fostered by team spirit), and the economic pillar (decreased healthcare expenses). While the third, environmental pillar is intuitively present, the low number of published studies remains a limitation to be overcome in future qualitative studies.

Systematic review of carbon footprint of surgical procedures

The ecological sustainability of the operating room (OR) is a matter of recent interest. The present systematic review aimed to review the current literature assessing the carbon footprint of surgical procedures in different surgical fields. Following to the PRISMA statement checklist, three databases (MEDLINE, EMBASE, Cochrane Library) were searched by independent reviewers, who screened records on title and abstract first, and then on the full text. Risk of bias was evaluated using the MINORS system. Over the 878 articles initially identified, 36 original studies were included. They considered ophthalmologic surgical procedures (30.5%), general/digestive surgery (19.4%), gynecologic procedures (13.9%), orthopedic procedures (8.3%), neurosurgery (5.5%), otolaryngology/head and neck surgery (5.5%), plastic/dermatological surgery (5.5%), and cardiac surgery (2.8%). Despite a great methodological heterogeneity, data showed that a single surgical procedure emits 4-814 kgCO2e, with anesthetic gases and energy consumption representing the largest sources of greenhouse gas emission. Minimally invasive surgical techniques may require more resources than conventional open surgery, particularly for packaging and plastics, energy use, and waste production. Each OR has the potential to produce from 0.2 to 4kg of waste per case with substantial differences depending on the type of intervention, hospital setting, and geographic area. Overall, the selected studies were found to be of moderate quality. Based on a qualitative synthesis of the available literature, the OR can be targeted by programs and protocols implemented to reduce the carbon footprint and improve the waste stream of the OR.

Meta-analysis of randomized clinical trials comparing robotic versus laparoscopic surgery for mid-low rectal cancers

INTRODUCTION

Robotic surgery (RS) is experiencing major development, particularly in the context of rectal cancer. The aim of this meta-analysis was to summarize data from the literature, focusing specifically on the safety and effectiveness of robotic surgery in mid-low rectal cancers, based on the hypothesis that that robotic surgery can find its most rational indication in this anatomical location.

METHOD

The meta-analysis was conducted according to the PRISMA 2000 recommendations, including all randomized trials that compared robotic surgery versus laparoscopic surgery (LS) that were found in the Medline-PICO, Cochrane Database, Scopus and Google databases. Data were extracted independently by two reviewers. The risk of bias was analyzed according to the Cochrane Handbook method and the certainty of the evidence according to the GRADE method. The analysis was carried out with R software Version 4.2-3 using the Package for Meta-Analysis "meta" version 6.5-0.

RESULTS

Eight randomized trials were included (with a total of 2342 patients), including four that focused specifically on mid-low rectal cancer (n=1,734 patients). No statistically significant difference was found for overall morbidity, intra-operative morbidity, anastomotic leakage, post-operative mortality, quality of mesorectal specimen, and resection margins. The main differences identified were a lower conversion rate for RS (RR=0.48 [0.24-0.95], p=0.04, I2=0%), and a longer operative time for RS (mean difference=39.11min [9.39-68.83], p<0.01, I2=96%). The other differences had no real clinical relevance, i.e., resumption of flatus passage (5hours earlier after RS), and lymph node dissection (one more lymph node for LS).

CONCLUSION

This meta-analysis does not confirm the initial hypothesis and does not show a statistically significant or clinically relevant benefit of RS compared to LS for mid-low rectal cancer.

A systematic review comparing the safety, cost and carbon footprint of disposable and reusable laparoscopic devices

INTRODUCTION

The objective of this systematic review of the literature is to compare a selection of currently utilized disposable and reusable laparoscopic medical devices in terms of safety (1st criteria), cost and carbon footprint.

MATERIAL AND METHODS

A search was carried out on electronic databases for articles published up until 6 May 2022. The eligible works were prospective (randomized or not) or retrospective clinical or medical-economic comparative studies having compared disposable scissors, trocars, and mechanical endoscopic staplers to the same instruments in reusable. Two different independent examiners extracted the relevant data.

RESULTS

Among the 2882 articles found, 156 abstracts were retained for examination. After comprehensive analysis concerning the safety and effectiveness of the instruments, we included four articles. A study on trocars highlighted increased vascular complications with disposable instruments, and another study found more perioperative incidents with a hybrid stapler as opposed to a disposable stapler. As regards cost analysis, we included 11 studies, all of which showed significantly higher costs with disposable instruments. The results of the one study on carbon footprints showed that hybrid instruments leave four times less of a carbon footprint than disposable instruments.

CONCLUSION

The literature on the theme remains extremely limited. Our review demonstrated that from a medical and economic standpoint, reusable medical instruments, particularly trocars, presented appreciable advantages. While there exist few data on the ecological impact, those that do exist are unmistakably favorable to reusable instruments.

Surgery, innovation, research and sustainable development

In the healthcare sector, surgery (especially in the operating theatre) is responsible for emission of greenhouse gases, which is a source of global warming. The goal of this largely quantitative assessment is to address three questions on carbon footprint associated with surgery, the role of primary and secondary prevention prior to surgical procedures, and incorporation of the carbon footprint into judgment criteria in research and surgical innovations. It appears that while the impact of surgery on global warming is undeniable, its extent depends on means of treatment and geographical location. Before and after an operation, primary, secondary and tertiary prevention accompanied by surgical sobriety (avoiding unnecessary or unjustified actions) can be virtuous in terms of sustainable development. However, the sanitary benefits of these actions are often opposed to environmental benefit, which has yet to be satisfactorily assessed. Lastly, the carbon footprint has yet to be incorporated into research protocols or the innovations under development. This should impel us not only to sensitize the different healthcare actors to relevant issues, but also to improve working conditions.

Is systematic histological examination of the cholecystectomy specimen always necessary?

INTRODUCTION

The histological examination (HE) of all cholecystectomy specimens removed for cholelithiasis is a widespread practice to rule out unrecognized gallbladder cancer. (GBC). But this dogmatic practice has been called into question by recent published data. The aim of this literature review was to answer two questions: (1) can HE be omitted in specific cases; (2) under what conditions is a selective strategy indicated?

METHODS

A review of the literature was carried out that included selected multicenter studies, registry studies, or meta-analyses. A reliable technique for the surgeon's macroscopic examination of the specimen would allow the selection of dubious cases for HE. The cost-effectiveness of selective HE was discussed. The PICO methodology (population, intervention, comparator, outcome) was used in the selection of articles that compared routine and selective histological examination.

RESULTS

If cases from countries with a high prevalence of gallbladder cancer are excluded and in the absence of high-risk situations (advanced age, female gender, calcified or porcelain gallbladder, acute cholecystitis, polyps, abnormalities noted intra-operatively), the macroscopic examination of the gallbladder in the operating room has a reliability approaching 100% in the majority of published studies. This would make it possible to omit systematic HE without compromising the diagnosis and prognosis of patients with unsuspected GBC and with a very favorable cost-effectiveness ratio.

CONCLUSION

Through a selection of patients at very low risk of incidentally-discovered cancer and a routine macroscopic examination of the opened gallbladder, the strategy of selective HE could prove useful in both clinical and economic terms.

Perioperative nutritional assessment and support in visceral surgery

Malnutrition in visceral surgery is frequent; it calls for screening prior to an operation, and its postoperative occurrence should be sought out and prevented, if possible. Organization of an individualized nutritional support strategy is based on systematic nutritional assessment and adapted to the type of surgery, the objectives being to forestall malnutrition and to reduce induced morbidity (immunosuppression, delayed wound healing, anastomotic fistulas…). Nutritional support is part and parcel of enhanced recovery after surgery (ERAS), and has shown effectiveness in the field of visceral surgery. Oral feeding should always be privileged to the greatest possible extent, complemented if necessary by nutritional supplements. If nutritional support is required, enteral nutrition should be favored over parenteral nutrition. As for the role of pharmaco-nutrition or immuno-nutrition, it remains ill-defined. Lastly, each type of visceral surgery entails specific modifications of the anatomy of the digestive system and is liable to have specific functional consequences, which should be known and taken into account in view of effectively tailoring nutritional support.

Picture of Peri-Operative Antisepsis Practices (PPAP Survey) in France

Abstract Background: Surgical skin preparation is performed according to peri-operative antisepsis protocols. These protocols are based on clinical practice recommendations and may vary from institution to institution. Materials and Methods: The objective of the survey, conducted among 481 surgeons and 98 scrub nurses of five specialties (cardiac, gastrointestinal, obstetrics and gynecology, orthopedics, and urology) in France was to take stock of practices to identify the protocols used for surgical skin preparation, such as measures relating to pre-operative showering, hair removal, or antisepsis of the operating area. Results: Two pre-operative showers with hair washing are usually carried out on the same day as the procedure (63%) or the day before the procedure (37%), mostly with an antiseptic (54%, soap 42%). Hair removal and cleaning/scrubbing are most often performed before the procedure (in 62% and 79% of cases, respectively). Alcoholic povidone-iodine is the most widely used antiseptic, and 81% of surgeons opt for complete spontaneous drying. Before making the incision, 41% of surgeons use drapes and 62% opt for an operative field irrigation technique during or at the end of the procedure. Surgeons mainly use running subcuticular sutures or running locking sutures (39%) and 93% use dressings. Thirty-six percent of the surgeons surveyed said the antisepsis protocols described were likely to be adapted. Conclusions: The results showed that international and French recommendations are mostly well followed by surgeons and scrub nurses in France. However, some differences are observed between surgical specialties, depending on the clinical situations encountered and the type of practice.

Obesity, sleeve gastrectomy and gastro-esophageal reflux disease

Sleeve gastrectomy (SG) is the most frequently performed operation for morbid obesity in the world. In spite of its demonstrated efficacy, the Achilles' Heel of this procedure seems to be either pre-existing or de novo gastro-esophageal reflux disease (GERD) with its potential complications such as peptic esophagitis, Barrett's esophagus and, in the long-term, esophageal adenocarcinoma. According to factual literature, it appears clear that Roux-en-Y gastric bypass is the preferred choice in case of pre-existing GERD or hiatal hernia discovered during preoperative workup for bariatric surgery. Nonetheless, certain authors propose performance of SG with an associated antireflux procedure such as Nissen fundoplication. Strict endoscopic surveillance is recommended after bariatric surgery. Revisional surgery (conversion of SG into Roux-en-Y gastric bypass (RYGB)) is the treatment of choice for patients who develop GERD after SG when conservative treatment (modified lifestyle and proton pump inhibitors) has failed. Lastly, with regard to the risk of esophageal adenocarcinoma after SG, large scale studies with adequate follow-up are necessary to come to factual conclusions. In all cases, the management of this conundrum remains a major technical challenge that has to be taken in consideration in future years, especially because of the current expansion of bariatric surgery.

Effect of oral antimicrobial prophylaxis on surgical site infection after elective colorectal surgery: multicentre, randomised, double blind, placebo controlled trial

OBJECTIVE

To investigate whether oral antimicrobial prophylaxis as an adjunct to intravenous antibiotic prophylaxis reduces surgical site infections after elective colorectal surgery.

DESIGN

Multicentre, randomised, double blind, placebo controlled trial.

SETTING

11 university and non-university hospitals in France between 25 May 2016 and 8 August 2019.

PARTICIPANTS

926 adults scheduled for elective colorectal surgery.

INTERVENTION

Patients were randomised to receive either a single 1 g dose of ornidazole (n=463) or placebo (n=463) orally 12 hours before surgery, in addition to intravenous antimicrobial prophylaxis before surgical incision.

MAIN OUTCOME MEASURES

The primary outcome was the proportion of patients with surgical site infection within 30 days after surgery. Secondary outcomes included individual types of surgical site infections and major postoperative complications (Clavien-Dindo classification grade 3 or higher) within 30 days after surgery.

RESULTS

Of the 960 patients who were enrolled, 926 (96%) were included in the analysis. The mean age of participants was 63 years and 554 (60%) were men. Surgical site infection within 30 days after surgery occurred in 60 of 463 patients (13%) in the oral prophylaxis group and 100 of 463 (22%) in the placebo group (absolute difference -8.6%, 95% confidence interval -13.5% to -3.8%; relative risk 0.60, 95% confidence interval 0.45 to 0.80). The proportion of patients with deep infections was 4.8% in the oral prophylaxis group and 8.0% in the placebo group (absolute difference -3.2%, 95% confidence interval -6.4% to -0.1%). The proportion of patients with organ space infections was 5.0% in the oral prophylaxis group and 8.4% in the placebo group (absolute difference -3.4%, -6.7% to -0.2%). Major postoperative complications occurred in 9.1% patients in the oral prophylaxis group and 13.6% in the placebo group (absolute difference -4.5%, -8.6% to -0.5%).

CONCLUSION

Among adults undergoing elective colorectal surgery, the addition of a single 1 g dose of ornidazole compared with placebo before surgery significantly reduced surgical site infections.

Acute urinary retention and urinary tract infection after short-course urinary drainage in colon or high rectum anastomoses: Post hoc analysis of a multicentre prospective database from the GRACE group

AIM

The aim was to define the risk factors for acute urinary retention (AUR) and urinary tract infections (UTIs) in colon or high rectum anastomosis patients based on the absence of a urinary catheter (UC) or the early removal of the UC (<24 h).

METHOD

This is a multicentre, international retrospective analysis of a prospective database including all patients undergoing colon or high rectum anastomoses. Patients were part of the enhanced recovery programme audit, developed by the Francophone Group for Enhanced Recovery after Surgery, and were included if no UC was inserted or if a UC was inserted for <24 h.

RESULTS

In all, 9389 patients had colon or high rectum anastomoses using laparoscopy, open surgery or robotic surgery. Among these patients, 4048 were excluded because the UC was left in place >24 h (43.1%) and 97 were excluded because the management of UC was unknown (1%). Among the 5244 colon or high rectum anastomoses patients included, AUR occurred in 5.2% and UTI occurred in 0.7%. UCs were in place for <24 h in 2765 patients (52.7%) and 2479 did not have UCs in place (47.3%). Multivariate analysis showed that management of the UC was not significantly associated with the occurrence of AUR and that risk factors for AUR were male gender, ≥65 years old, having an American Society of Anesthesiologists score ≥3 and receiving epidural analgesia. Conversely, being of male gender was a protective factor of UTI, while being ≥65 years old, having open surgery and receiving epidural analgesia were risk factors for UTIs. The management of the UC was not significantly associated with the occurrence of UTIs but the occurrence of AUR was a more significant risk factor for UTIs.

CONCLUSION

UCs in place for <24 h did not reduce the occurrence of AUR or UTI compared to the absence of UCs.

Probiotics/Synbiotics to Reduce Infectious Complications after Colorectal Surgery: A Systematic Review and Meta-Analysis of Randomised Controlled Trials

Aim: The aims of this systematic review and meta-analysis were to assess to what extent probiotics/synbiotics reduce infectious complications after colorectal surgery and whether probiotics or synbiotics should be considered as perioperative measures preventing or reducing infectious complications after CRS and should be included in enhanced recovery programmes (ERP). Secondary aims were to answer practical questions precisely on the best formulation and the type and timing of probiotics or synbiotics in CRS. Method: This systematic review and quantitative meta-analysis were conducted in accordance with PRISMA 2020 guidelines. Inclusion criteria were randomised trials comparing perioperative probiotics/synbiotics with a placebo or standard care in elective colorectal surgery. Exclusion criteria were non-randomised trials. Overall infectious complications and surgical site infections (SSIs including both deep abdominal infections and wound (skin or under the skin) infections) were the primary outcomes. Secondary outcomes were pulmonary and urinary infections, wound infections, and anastomotic leaks. The databases consulted were Medline, Cochrane Database of Systematic Reviews, Scopus, and Clinical Trials Register. Risk of bias was assessed according to the GRADE approach. The analysis calculated the random effects estimates risk ratio (RR) for each outcome. Results: 21 trials were included; 15 evaluated probiotics, and 6 evaluated synbiotics. There were significantly fewer infectious complications (risk ratio (RR) 0.59 [0.47–0.75], I² = 15%) and fewer SSI (RR 0.70 [0.52–0.95], I² = 0%) in the probiotic or synbiotic group. There were also significantly fewer pulmonary infections (RR 0.35 [0.20–0.63]) and urinary infections RR 0.41 [0.19–0.87]) as opposed to anastomotic leaks (RR 0.83 [0.47–1.48]) and wound infections (RR 0.74 [0.53–1.03]). Sensitivity analyses showed no significant difference between probiotics and synbiotics in reducing postoperative infections (RR 0.55 [0.42–0.73] versus RR 0.69 [0.42–1.13], p = 0.46). Conclusions: Based on the finding of this study, probiotics/synbiotics reduce infectious complications after colorectal surgery. The effect size was more pronounced for pulmonary and urinary infections. From a practical aspect, some of the questions related to formulations and duration of probiotics or synbiotics need to be answered before including them definitively in enhanced recovery after colorectal surgery programmes.

Five-Year Changes in Weight and Diabetes Status After Bariatric Surgery for Craniopharyngioma-Related Hypothalamic Obesity: a Case-Control Study

PURPOSE

Craniopharyngiomas are tumors located in the hypothalamic region which leads to obesity in about 50% of cases. Long-term efficacy and safety of bariatric surgery are lacking in this peculiar population. The aim of this study is to determine the 5-year weight loss and resolution of type 2 diabetes (T2D) after bariatric surgery in patients operated on craniopharyngioma who had developed hypothalamic obesity.

MATERIALS AND METHODS

This is a multicenter french retrospective case-control study. Subjects with craniopharyngioma (n = 23) who underwent sleeve gastrectomy (SG) (n = 9) or Roux-en-Y gastric bypass (RYGB) (n = 14) (median age 35 years [25;43] and BMI 44.2 kg/m² [40.7; 51.0]; 8/23 with T2D) were individually matched to 2 subjects with common obesity for age, gender, preoperative body mass index, T2D, and type of surgery.

RESULTS

TWL% after 1 and 5 years was lower in the craniopharyngioma group than in the control group: 23.1 [15.4; 31.1] (23/23) vs 31.4 [23.9; 35.3] at 1 year (p = 0.008) (46/46) and 17.8 [7.1; 21.9] (23/23) vs 26.2 [18.9; 33.9] at 5 years (p = 0.003) (46/46). After RYGB, TWL% was lower in the craniopharyngioma group compared to the control group (p < 0.001) and comparable after SG both at 1 and 5 years. No difference between the two groups was observed in T2D remission rate and in early and late adverse events. No hormonal deficiency-related acute disease was reported.

CONCLUSIONS

Bariatric surgery induced a significant weight loss in the craniopharyngioma group at 1 and 5 years, but less than in common obesity. SG may be more effective than RYGB but this remains to be demonstrated in a larger cohort.

Favorable effect of enhanced recovery programs on post-discharge mortality: a French nationwide study

Background

Enhanced recovery programs (ERPs) imply early discharge but few papers have assessed the effect of ERPs on post-discharge mortality (PDM).

Methods

A multicenter nationwide case control study based on administrative data was carried out between March and December 2019. Coding for every episode of care whether in the setting of ERP or not is mandatory for hospital funding (public or private). Twelve surgical specialties or procedures were included. The episodes of care coded with ERP were matched with those without ERP code for several factors such as the type of hospital (public or private), age, gender, month of discharge, and updated Charlson score. Ninety-day PDM was the main outcome.

Results

Of 420,031 patients in the database, 78,119 had an ERP code. Finally, 132,600 patients with 66,300 matched pairs were considered for the study. Overall, PDM was significantly reduced after ERPs: 0.075% vs 0.138% (p = 0.00042). Significant one-half and two-thirds reduction in PDM was observed respectively after hip arthroplasty (odds ratio 0.48 [95% CI 0.21–0.99]) and colectomy (odds ratio 0.36 [95% CI 0.16–0.74]).

Conclusion

The findings, based on a large database and a rigorous matching, strongly suggest that ERPs reduce PDM particularly after colectomy and hip arthroplasty. This is likely due to better post-operative care in ERPs.

To what extent is enhanced recovery in surgery used in French obstetrics and gynecology departments?: use of enhanced recovery in gynecologic and obstetric surgery in France

The objective of the present study was to evaluate the implementation of Enhanced Recovery in Surgery (ERS) in French obstetrics and gynecology departments. To achieve this objective, we drafted an online questionnaire about ERS protocols for caesarean sections and hysterectomies with a benign indication and put a hyperlink on the 'French National College of Gynecologists and Obstetricians' (Collège National des Gynécologues et Obstétriciens Français) website. We obtained 112 analyzable responses. Respectively 66% and 34% of the surveyed departments had established ERS protocols for cesarean sections and for hysterectomies with a benign indication. However, not all of the key ERS items were sufficiently implemented: despite the establishment of written protocols, the degree of compliance with the guidelines issued by the French-Speaking Group for Enhanced Recovery After Surgery (Groupement Francophone de Réhabilitation Améliorée Après Chirurgie) was variable. There are few published data on the implementation of ERS in obstetrics and gynecology departments worldwide. In 2010, the Enhanced Recovery After Surgery® Society issued guidelines and a checklist for an ERS protocol. The literature data suggest that for most surgical disciplines, the main ERS criteria are not well known or not widely applied. ERS protocols are still not widespread in French gynecologic surgery departments. Moreover, the application of some of the major ERS items differs markedly from one ERS program to other, which is likely to reduce the level of effectiveness. It therefore appears to be essential to formalize and promote ERS protocols in gynecological surgery.

Medico-economic impact of enhanced rehabilitation after surgery: an exhaustive, nation-wide claims study

Background

Study of the medico economic impact of enhanced rehabilitation after surgery (ERAS), by comparing the cost of patient care with or without ERAS, both from the point of view of the hospitals and the Social Security Health Insurance Program.

Methods

Retrospective longitudinal study on matched data from March 1, 2019 to December 31, 2019. The data are extracted from the French prospective payment system. We studied 12 of the most commonly performed in ERAS business segments. The primary outcome was the reduction of the average length of hospital stay and its implications on production costs and excess capacity. We also studied the impact on hospital incomes and Social Security Insurance Program expenses. The potential gain in hospital days was computed by comparing the length of stay of ERAS and non-ERAS cases. The cost reduction was estimated using the mean number of avoidable days of hospitalization, and the mean cost of the stays obtained from the national cost study. Finally, we studied an approximation of the additional expense for the Social Security Health Insurance Program on costs standardized by applying public sector rates.

Results

The average length of stay reduction attributed to ERAS is 1.45 (CI 95% 1.42 to 1.48) day per stay, translating to a cost reduction for the hospitals of € 1060 (CI 95% 995 to 1125) per patient and a total of €65 million (CI 95% 61 to 69). At the same time, the additional expenses for the Social Security Insurance Program can conservatively be approximated to € 1.6 million, breaking into a € 2.2 million increase partially compensated by cost savings of € 0.6 million over subsequent stays for complications. Overall, for each percent of additional ERAS activity over the scope of the study, the marginal cost reduction for the hospitals can be estimated to € 1.8 million (CI 95% 1.7 million to 2.0 million).

Conclusions

Associated with previously known clinical benefits for the patients, these convincing results in terms of economic gain strongly support expanding the adoption of ERAS.

Umbrella reviews: A new tool to synthesize scientific evidence in surgery

Researchers and practitioners are faced with an exponential increase in the number of systematic reviews (SRs) (with or without meta-analysis), a so-called `secondary' research method that synthesizes data from primary research. This growing number, sometimes with discordant results on the same subject or with non-conclusions, has led to the introduction of the concept of reviews to synthesize SR in order to combine scientific knowledge useful to practitioners. These so-called ``umbrella reviews'' (UR) constitute a new tertiary research tool. Surgical research is no exception to this development but umbrella surgical reviews remain relatively rare. Any UR must be transparent and meet rigorous methodological criteria. The UR could thus provide answers to practical questions in the field of surgery, but only on condition that the bias of the included SRs is limited. Let us not forget that the base requirement of clinical surgical research remains the good methodological quality of clinical studies (primary research). Only thus can SRs or URs (secondary or tertiary research) be more useful and decisive.

Systematic review and meta-analysis of early removal of urinary catheter after colorectal surgery with infraperitoneal anastomosis

AIM OF THE STUDY

To review and to analyse the feasibility of using no urinary catheter or a catheter for less than 24 h compared with longer post-operative catheter after colorectal surgery with infraperitoneal dissection.

METHODS

We performed a systematic review and meta-analysis of studies comparing no urinary catheter or a catheter for less than 24 h (early removal, ER) and urinary catheter drainage for 2 days or longer (late removal, LR) after colorectal surgery with infraperitoneal dissection. Primary endpoint was acute urinary retention (AUR) requiring a re-catheterization. Secondary endpoints were urinary tract infection (UTI), overall morbidity and hospital length of stay. Meta-analysis met the PRISMA criteria, with a random model.

RESULTS

Out of 3659 articles found, 82 comparative studies on catheter duration were selected, of which five were in colorectal surgery: three randomized trials, one retrospective and one prospective series. There were 396 ER and 410 LR patients. All had undergone surgery with infraperitoneal dissection. There was no significant difference regarding AUR (OR = 2.09 [95%CI 0.97-4.52]) but significantly less UTI (OR = 0.39 [95%CI 0.22-0.67]) for early urinary catheter removal. The number needed to harm was much higher for AUR than for UTI (23.3 vs. 8).

CONCLUSION

This meta-analysis suggests that, in terms of benefit/risk ratio, in colorectal surgery with infraperitoneal anastomosis, early removal (< 24 h) of the urinary catheter would be beneficial (because of a more frequent UTI after LR than AUR after ER) and would reduce the occurrence of UTI if no AUR risk factors are present. However, these findings should be interpreted with caution because of the low quality of evidence.

Efficacy of perioperative immunonutrition in visceral surgery: an umbrella review protocol

INTRODUCTION

Immunonutrition (IN) is generally used before major visceral surgery with the intent to reduce postoperative complications, especially infectious ones. However, the conclusions of published meta-analyses are conflicting. The purpose of this review is to synthesise the data of published systematic reviews on the effectiveness of IN.

METHODS AND ANALYSIS

This protocol follows the Preferred Reporting Items for Systematic Reviews and Meta-analyses Protocols guidelines. This is an umbrella review of systematic reviews comparing IN (delivered orally 5-7 days preoperatively) with normal diet or isocaloric isonitrogenous feeding before visceral surgery performed on any of several viscera (colorectum, stomach, pancreas, liver, oesophagus). We search the systematic reviews included in the main bibliographic databases. To assess the efficacy of IN, several outcomes will be considered: the main outcome is infectious complications (surgical site infections, pulmonary infections or urinary infections) and secondary outcomes are overall morbidity, hospital length of stay and mortality. Identified reviews will be screened by two independent assessors. The methodological quality of relevant included reviews will be assessed using A MeaSurement Tool to Assess systematic Reviews (AMSTAR) instrument. The data extracted from included reviews will be synthesised using the r-Metafor package considering separate groups according to the viscus of interest. Publication bias will be evaluated, and subgroup analyses will be performed according to the quality of studies and preoperative nutritional status.

ETHICS AND DISSEMINATION

An umbrella review based on published data from systematic reviews needs no ethical approval. Furthermore, no patient will be involved in the review. Once terminated, the review will be submitted for publication in an open access journal to ensure wide dissemination of the findings.

The impact of enhanced recovery program compliance after elective liver surgery: Results from a multicenter prospective national registry

BACKGROUND

The Enhanced Recovery Program after surgery is a multimodal, evidence-based protocol of care developed to minimize the response to surgical stress. Data on the influence of ERP on outcomes, particularly according to the complexity of liver surgery, are lacking.

METHODS

A prospective multicenter cohort of patients undergoing liver surgery and exposed to Enhanced Recovery Program from 2016 to 2020 in France was analyzed. High Enhanced Recovery Program compliance was defined as more than 70% of items (15 out of 21). The outcomes were the rate of complications, length of stay, and functional recovery according to Enhanced Recovery Program compliance.

RESULTS

A total of 297 patients were included in the study, and they had 61.9% overall compliance (median = 13 items, interquartile range 11-15). Complications were observed in 32.2% (n = 95) of cases, and the mean length of hospital stay was 7.28 (±7.15) days overall. A longer duration of liver surgery was associated with an increase in the complication rate, while high compliance was independently associated with a reduced risk of complications in the multivariable analysis.

CONCLUSION

High Enhanced Recovery Program compliance was associated with a lower rate of postoperative complexity.

Feasibility of low-pressure pneumoperitoneum is feasible in expert hand. Its efficacy within enhanced recovery programmes and its safety need to be demonstrated in future studies

Impact of non-steroidal anti-inflammatory drugs on the efficiency of enhanced recovery programmes after colorectal surgery: a retrospective study of the GRACE database

BACKGROUND

Multimodal analgesia is considered a key element of enhanced recovery programmes (ERPs) after colorectal surgery. We investigated the effects of NSAIDs, a major component of multimodal analgesia on adherence to ERP, incidence of postoperative complications, and length of hospital stay (LOS).

METHODS

This was a retrospective study of the GRACE database that included 8611 patients scheduled for colorectal surgery with an ERP between February 2016 and November 2019. Primary endpoints were adherence to the postoperative protocol, the rate and type of postoperative complications, and LOS. Data are median [IQR] and number (per cent). Multivariate models were used to assess the effects of NSAIDs on these variables taking into account potential confounding factors.

RESULTS

Data from 8258 patients were analysed and classified into four groups according to whether NSAIDs had been given intra- and/or postoperatively or not at all; 4578 patients were given NSAIDs intra- and/or postoperatively and 3680 patients received no NSAIDs. Use of NSAIDs was significantly (P<0.001) associated with improved adherence to the postoperative protocol (4.0 [3.0-4.0] vs. 3.0 [2.0-4.0] items), a reduced incidence of complications (21.1% vs. 29.2%), and a shortened LOS (5.0 [3.0-7.0] vs. 6.0 [4.0-9.0] days) compared to the no-NSAIDs group. Multivariate analyses adjusted for the confounding factors confirmed a significant (P<0.001) beneficial impact of NSAIDs on these three primary endpoints.

CONCLUSION

This study suggests that perioperative NSAID use results in better adherence to the postoperative protocol, fewer postoperative in-hospital complications, and shorter LOS after colorectal surgery.

Conceptual innovation: 4P Medicine and 4P surgery

The aim of this article is to present the concept of "4P medicine" i.e., medicine that is Personalized, Preventive, Predictive, and Participatory. We will discuss the evolution from cure-focused traditional medicine toward personalized medicine based on genome analysis. This new approach is illustrated by several clinical examples such as prevention of cardiovascular diseases (primary and secondary), prophylactic cancer surgery, targeted therapies, targeted peri-operative care and patient participation in their care. Finally, it will discuss the impact of this development on the health system of the future and the ethical questions raised by this new approach.

Evidence-based evaluation of abdominal drainage in pancreatic surgery

Pancreatic fistula is the most common and dreaded complication after pancreatic resection, responsible for high morbidity and mortality (2 to 30%). Prophylactic drainage of the operative site is usually put in place to decrease and/or detect postoperative pancreatic fistula (POPF) early. However, this policy is currently debated and the data from the literature are unclear. The goal of this update is to analyze the most recent evidence-based data with regard to prophylactic abdominal drainage after pancreatic resection (pancreatoduodenectomy [PD] or distal pancreatectomy [PD]). This systematic review of the literature between 1990 and 2020 sought to answer the following questions: should drainage of the operative site after pancreatectomy be routine or adapted to the risk of POPF? If a drainage is used, how long should it remain in the abdomen, what criteria should be used to decide to remove it, and what type of drainage should be preferred? Has the introduction of laparoscopy changed our practice? The literature seems to indicate that it is not possible to recommend the omission of routine drainage after pancreatic resection. By contrast, an approach based on the risk of POPF using the fistula risk score seems beneficial. When a drain is placed, early removal (within 5 days) seems feasible based on clinical, laboratory (C-reactive protein, leukocyte count, neutrophile/lymphocyte ratio, dosage and dynamic of amylase in the drains on D1, D3±D5) and radiological findings. This is in line with the development of enhanced recovery programs after pancreatic surgery. Finally, this literature review did not find any specific data relative to mini-invasive pancreatic surgery.

Equipment failures in laparoscopic surgery: Causes and consequences

OBJECTIVE

The aim of this study was to assess incidence, causes and consequences of equipment failures in a high volume, advanced endoscopic surgery department.

METHODS

This is a prospectical observational single centre study between April and July of 2019 in the Gynecological surgery department of the Estaing University Hospital of Clermont-Ferrand, France. During the study period, 171 laparoscopies were observed. Data were collected real time by three supernumerary observers.

RESULTS

In total, 66 (38.6%) laparoscopies were complicated by equipment failures. The bipolar cable and forceps accounted for 31% of the total amount of malfunctions in laparoscopy. Causes of malfunctions were in 45% due to the instrument per se and in 43% due to the incorrect combination of elements. Less commonly, the equipment was not available or a mismatched was reported. The total length of the surgery increased by 1.35% due to the malfunctions. Human error was identified in 50% of cases. No morbility, neither mortality was reported in this series; however we observed 34 malfunctions that could have led to serious consequences for the patients and 3 incidents induced a real consequence on the operation workflow.

CONCLUSIONS

Equipment failure is a common event in endoscopy. On the opposite, time wasted for the malfunctions is low in laparoscopy, as it only accounts for 1.35% of the overall surgical time. Human decisions contributed to malfunctions in almost half of cases. This alarming finding may advise for intensification in training on instruments of the whole surgical team.
