Objective
Our aim was to conduct an up-to-date systematic review of randomised controlled trials (RCTs) to determine the benefits and harms of enhanced recovery after surgery (ERAS) programme in ...bariatric surgery.
Methods
MEDLINE, Embase, PubMed, CINAHL and the Cochrane Library were searched for RCTs on ERAS versus standard care (SC) until April 2020. The primary endpoint was the length of hospital stay (LOS).
Results
Five RCTs included a total of 610 procedures. ERAS adoption is capable of significantly reducing LOS (MD of − 0.51; 95% CI − 0.92 to − 0.10;
P
= 0.01) and postoperative nausea and vomiting (PONV) (OR 0.42; 95% CI 0.19 to 0.95;
P
= 0.04). No significant differences in terms of adverse events and readmissions.
Conclusions
The implementation of ERAS in bariatric surgery produces a significant reduction in LOS and PONV.
Professional surgical societies recommend the identification and treatment of pre-operative anaemia in patients scheduled for abdominal surgery. Our aim was to determine if pre-operative iron allows ...correction of haemoglobin concentration and decreased incidence of peri-operative blood transfusion in patients undergoing major abdominal surgery. MEDLINE, Embase and CENTRAL were searched for RCTs written in English and assessing the effect of pre-operative iron on the incidence of peri-operative allogeneic blood transfusion in patients undergoing major abdominal surgery. Pooled relative risk (RR), risk difference (RD) and mean difference (MD) were obtained using models with random effects. Heterogeneity was assessed using the Q-test and quantified using the I
value. Four RCTs were retained for analysis out of 285 eligible articles. MD in haemoglobin concentration between patients with pre-operative iron and patients without pre-operative iron was of 0.81 g/dl (3 RCTs, 95% CI 0.30 to 1.33, I
: 60%, p = 0.002). Pre-operative iron did not lead to reduction in the incidence of peri-operative blood transfusion in terms of RD (4 RCTs, RD: - 0.13, 95% CI - 0.27 to 0.01, I
: 65%, p = 0.07) or RR (4 RCTs, RR: 0.57, 95% CI 0.30 to 1.09, I
: 64%, p = 0.09). To conclude, pre-operative iron significantly increases haemoglobin concentration by 0.81 g/dl before abdominal surgery but does not reduce the need for peri-operative blood transfusion. Important heterogeneity exists between existing RCTs in terms of populations and interventions. Future trials should target patients suffering from iron-deficiency anaemia and assess the effect of intervention on anaemia-related complications.
Purpose
Concerns exist regarding the potential for transanal total mesorectal excision (TaTME) to yield poorer functional outcomes compared to laparoscopic TME (LaTME). The aim of this study is to ...assess the functional outcomes following taTME and LaTME, focusing on bowel, anorectal, and urogenital disorders and their impact on the patient’s QoL.
Methods
A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and A Measurement Tool to Assess systematic Reviews (AMSTAR) guidelines. A comprehensive search was conducted in Medline, Embase, Scopus, and Cochrane Library databases. The variables considered are: Low Anterior Resection Syndrome (LARS), International Prostate Symptom Score (IPSS) and Jorge-Wexner scales; European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C29 and QLQ-C30 scales.
Results
Eleven studies involving 1020 patients (497-taTME group/ 523-LaTME group) were included. There was no significant difference between the treatments in terms of anorectal function: LARS (MD: 2.81, 95% CI: − 2.45–8.08,
p
= 0.3; I2 = 97%); Jorge-Wexner scale (MD: -1.3, 95% CI: -3.22–0.62, p = 0.19). EORTC QLQ C30/29 scores were similar between the groups. No significant differences were reported in terms of urogenital function: IPSS (MD: 0.0, 95% CI: − 1.49–1.49,
p
= 0.99; I
2
= 72%).
Conclusions
This review supports previous findings indicating that functional outcomes and QoL are similar for rectal cancer patients who underwent taTME or LaTME. Further research is needed to confirm these findings and understand the long-term impact of the functional sequelae of these surgical approaches.
Background
Thoracic aortic aneurysm (TAA) is an uncommon disease with an incidence of 10.4 per 100,000 inhabitants. It occurs mainly in older individuals and is evenly distributed among both sexes. ...There are no signs or symptoms indicative of the presence of the disease. Progressive but unpredictable enlargement of the dilated aorta is the natural course of the disease and can lead to rupture. Open chest surgical repair using prosthetic graft interposition has been a conventional treatment for TAAs. Despite improvements in surgical procedures perioperative complications remain significant. The alternative option of thoracic endovascular aneurysm repair (TEVAR) is considered a less invasive and potentially safer technique, with lower morbidity and mortality compared with conventional treatment. Evidence is needed to support the use of TEVAR for these patients, rather than open surgery. This is an update of the review first published in 2009.
Objectives
This review aimed to assess the efficacy of TEVAR versus conventional open surgery in patients with thoracic aortic aneurysms.
Search methods
For this update the Cochrane Vascular Information Specialist searched the Specialised Register (last searched January 2016) and CENTRAL (2015, Issue 12).
Selection criteria
Randomised controlled trials in which patients with TAAs were randomly assigned to TEVAR or open surgical repair.
Data collection and analysis
Two review authors independently identified and evaluated potential trials for eligibility. Excluded studies were further checked by another author. We did not perform any statistical analyses as no randomised controlled trials were identified.
Main results
We did not find any published or unpublished randomised controlled trials comparing TEVAR with conventional open surgical repair for the treatment of thoracic aortic aneurysms.
Authors' conclusions
Stent grafting of the thoracic aorta is technically feasible and non‐randomised studies suggest reduction of early outcomes such as paraplegia, mortality and hospital stay. High quality randomised controlled trials assessing all clinically relevant outcomes including open‐conversion, aneurysm exclusion, endoleaks, and late mortality are needed.
The Italian burden of disease associated with infections due to antibiotic-resistant bacteria has been very high, largely attributed to Carbapenem-Resistant Klebsiella pneumoniae (CR-Kp). The ...implementation of infection control measures and antimicrobial stewardship programs (ASP) has been shown to reduce healthcare-related infections caused by multidrug resistance (MDR) germs. Since 2016, in our teaching hospital of Terni, an ASP has been implemented in an intensive care unit (ICU) setting, with the “daily-ICU round strategy” and particular attention to infection control measures. We performed active surveillance for search patients colonized by Carbapenem-Resistant Enterobacteriaceae (CRE). In March 2020, coronavirus disease 2019 (COVID-19) arrived and the same ICU was reserved only for COVID-19 patients. In our retrospective observational study, we analyzed the bimonthly incidence of CRE colonization patients and the incidence of CRE acquisition in our ICU during the period of January 2019 to June 2020. In consideration of the great attention and training of all staff on infection control measures in the COVID-19 era, we would have expected a clear reduction in CRE acquisition, but this did not happen. In fact, the incidence of CRE acquisition went from 6.7% in 2019 to 50% in March–April 2020. We noted that 67% of patients that had been changed in posture with prone position were colonized by CRE, while only 37% of patients that had not been changed in posture were colonized by CRE. In our opinion, the high intensity of care, the prone position requiring 4–5 healthcare workers (HCWs), equipped with personal protective equipment (PPE) in a high risk area, with extended and prolonged contact with the patient, and the presence of 32 new HCWs from other departments and without work experience in the ICU setting, contributed to the spread of CR-Kp in our ICU, determining an increase in CRE acquisition colonization.
Purpose
The aim of this study was to compare the outcomes of right hemicolectomy with CME performed with laparoscopic and open surgery.
Methods

register were searched. Primary outcome was the overall number of harvested lymph nodes. Secondary outcomes were short and long-term course variables. A meta-analysis was performed to calculate risk ratios.
Results
Twenty-one studies were identified with 5038 patients enrolled. The difference in number of harvested lymph nodes was not statistically significant (MD 0.68, − 0.41–1.76,
P
= 0.22). The only RCT shows a significant advantage in favour of laparoscopy (MD 3.30, 95% CI − 0.20–6.40,
P
= 0.04). The analysis of CCTs showed an advantage in favour of the laparoscopic group, but the result was not statically significantly (MD − 0.55, 95% CI − 0.57–1.67,
P
= 0.33). The overall incidence of local recurrence was not different between the groups, while systemic recurrence at 5 years was lower in laparoscopic group. Laparoscopy showed better short-term outcomes including overall complications, lower estimated blood loss, lower wound infections and shorter hospital stay, despite a longer operative time. The rate of anastomotic and chyle leak was similar in the two groups.
Conclusions
Despite the several limitations of this study, we found that the median number of lymph node harvested in the laparoscopic group is not different compared to open surgery. Laparoscopy was associated with a lower incidence of systemic recurrence.
Objective
This study aimed to evaluate the incidence of chronic groin pain (primary outcome) and alterations of sensitivity (secondary outcome) after Lichtenstein inguinal hernia repair, comparing ...neurectomy with ilioinguinal nerve preservation surgery.
Summary background data
The exact cause of chronic groin postoperative pain after mesh inguinal hernia repair is usually unclear. Section of the ilioinguinal nerve (neurectomy) may reduce postoperative chronic pain.
Methods
We followed PRISMA guidelines to identify randomized studies reporting comparative outcomes of neurectomy versus ilioinguinal nerve preservation surgery during Lichtenstein hernia repairs. Studies were identified by searching in PubMed, Scopus, and Web of Science from April 2020. The protocol for this systematic review and meta-analysis was submitted and accepted from PROSPERO: CRD420201610.
Results
In this systematic review and meta-analysis, 16 RCTs were included and 1550 patients were evaluated: 756 patients underwent neurectomy (neurectomy group) vs 794 patients underwent ilioinguinal nerve preservation surgery (nerve preservation group). All included studies analyzed Lichtenstein hernia repair. The majority of the new studies and data comes from a relatively narrow geographic region; other bias of this meta-analysis is the suitability of pooling data for many of these studies.
A statistically significant percentage of patients with prosthetic inguinal hernia repair had reduced groin pain at 6 months after surgery at 8.94% (38/425) in the neurectomy group versus 25.11% (113/450) in the nerve preservation group relative risk (RR) 0.39, 95% confidence interval (CI) 0.28–0.54; Z = 5.60 (
P
< 0.00001). Neurectomy did not significantly increase the groin paresthesia 6 months after surgery at 8.5% (30/353) in the neurectomy group versus 4.5% (17/373) in the nerve preservation group RR 1.62, 95% CI 0.94–2.80; Z = 1.74 (
P
= 0.08). At 12 months after surgery, there is no advantage of neurectomy over chronic groin pain; no significant differences were found in the 12-month postoperative groin pain rate at 9% (9/100) in the neurectomy group versus 17.85% (20/112) in the inguinal nerve preservation group RR 0.50, 95% CI 0.24–1.05; Z = 1.83 (
P
= 0.07). One study (115 patients) reported data about paresthesia at 12 months after surgery (7.27%, 4/55 in neurectomy group vs. 5%, 3/60 in nerve preservation group) and results were not significantly different between the two groups RR 1.45, 95% CI 0.34, 6.21;Z = 0.51 (
P
= 0.61). The subgroup analysis of the studies that identified the IIN showed a significant reduction of the 6th month evaluation of pain in both groups and confirmed the same trend in favor of neurectomy reported in the previous overall analysis: statistically significant reduction of pain 6 months after surgery at 3.79% (6/158) in the neurectomy group versus 14.6% (26/178) in the nerve preservation group RR 0.28, 95% CI 0.13–0.63; Z = 3.10 (
P
= 0.002).
Conclusion
Ilioinguinal nerve identification in Lichtenstein inguinal hernia repair is the fundamental step to reduce or avoid postoperative pain. Prophylactic ilioinguinal nerve neurectomy seems to offer some advantages concerning pain in the first 6th month postoperative period, although it might be possible that the small number of cases contributed to the insignificancy regarding paresthesia and hypoesthesia.
Nowadays, prudent surgeons should discuss with patients and their families the uncertain benefits and the potential risks of neurectomy before performing the hernioplasty.
Background and aims
This systematic review and meta-analysis compares the safety and effectiveness of endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) in the treatment of ...flat and sessile colorectal lesions >20 mm preoperatively assessed as noninvasive.
Methods
We reviewed the literature published between January 2000 and March 2014. Pooled estimates of the proportion of patients with en bloc, R0 resection, complications, recurrence, and need for further treatment were compared in a meta-analysis using fixed and random effects.
Results
A total of 11 studies and 4678 patients were included. The en bloc resection rate was 89.9% for ESD vs 34.9% for EMR patients (RR 1.93 p < 0.001). The R0 resection rate was 79.6% for ESD vs 36.2% for EMR patients (RR 2.01 p < 0.001). The rate of perforation was 4.9% for the ESD group and 0.9% for EMR (RR 3.19, p < 0.001), while the rate of bleeding was 1.9% for ESD and 2.9% for EMR (RR 0.68, p = 0.070). Therefore, the overall need for further surgery, including surgery for oncologic reasons and surgery for complications, was 7.8% for ESD and 3.0% for EMR (RR 2.40, p < 0.001).
Conclusions
ESD achieves a higher rate of en bloc and R0 resection compared to EMR, at the cost of a higher risk of complications. This, added to an increased need for surgery for oncologic reasons for a plausible tendency to extend indication for endoscopic excision, increases the risk of further surgery after ESD.
