Review
BACKGROUND
The development of prolonged post-operative ileus (POI) remains a significant problem in the general surgical patient population. The aetiology of ileus is poorly understood and management options/preventative measures are currently extremely limited. The pathophysiology leading to a post-operative ileus is relatively poorly understood, and there is no validated method to estimate ileus occurrence or duration. Ileus in the post-operative period commonly occurs following major colorectal surgery and leads to painful abdominal distension, vomiting, nutritional deficit, pneumonia, prolonged hospital stays and susceptibility to hospital-acquired infection. An increased hospital stay, the burden of treatment costs and the burden on the health system highlight the importance of future research on finding definitions, preventions and predictions of ileus.
METHODS
A systematic literature review was performed to identify randomized controlled trials (RCTs) comparing the rate of ileus on various treatments for prolonged post-operative ileus following colorectal surgery. A confidence evaluation in a meta-analysis were performed using CINeMA. Direct and indirect comparisons of all interventions were simultaneously carried out using a network meta-analysis. The level of certainty was appraised using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. The method of assessing the risk of bias, the quality assessment, used the Cochrane Risk of Bias 2 tool (RoB2).
RESULTS
Among the seven included studies, the majority suffered from considerable within-study bias, affecting the confidence rates of study findings. Heterogeneity and incoherence made the pairwise meta-analysis and ranking of interventions unfeasible. Indirect comparisons were considered unreliable due to this incoherence.
CONCLUSIONS
This systematic review, with a confidence evaluation in the network meta-analysis, determined that there is a knowledge gap in the field of study on prolonged ileus following digestive surgery. The current evidence suffers from heterogeneity and incoherence more than imprecision. There is a gap in the data on ileus occurrence in interventional trials for digestive surgery. This could inform clinicians and trialists to better appraise the current literature and plan future trials.

Meta-Analysis
BACKGROUND
The benefits of immunonutrition in patients who underwent major abdominal surgery have been recently established, but the optimal combination of immunonutrients has remained unclear. The aim is to clarify this point.
METHODS
A systematic search of randomized clinical trials about immunonutrition in major abdominal surgery was made. A frequentist random-effects component network meta-analysis was conducted, reporting the P score and odds ratio or mean difference with a 95% confidence interval. The best components and best plausible strategies were described. The critical endpoints were morbidity and mortality rates. The important endpoints were infectious complication rate and length of stay.
RESULTS
The meta-analysis includes 87 studies and 8,375 patients. The best approach for morbidity rate, with a moderate grade of certainty, was the use of perioperative enteral/oral immunonutrition with arginine, glutamine, and polyunsaturated fatty acids (odds ratio 0.32; 0.10 to 0.98; P score of 0.93). The mortality rate was reduced by postoperative enteral immunonutrition with RNA, arginine, and polyunsaturated fatty acids (odds ratio 59; 0.29 to 1.22; P score 0.84) but with a low grade of certainty. No significant heterogeneity or incoherence is observed. The length of stay and infectious results are "at risk" for high heterogeneity or network meta-analysis incoherence. The component analysis confirmed that postoperative oral/enteral use of 2 or 3 components is crucial to reducing morbidity rate.
CONCLUSION
The oral/enteral immunonutrition in the postoperative period, with multiple immunonutrients, can reduce the morbidity rate in patients undergoing major abdominal surgery. The effect of immunonutrition on mortality, infectious disease, and length of stay is unclear.

Meta-Analysis Review
Efficacy of Preemptive Dexamethasone versus Methylprednisolone in the Management of Postoperative Discomfort and Pain after Mandibular Third Molar Surgery: A Systematic Review and Meta-Analysis.
The corticosteroids have been used for preemptive management of surgical sequelae after mandibular third molar extraction. The aim of this article was to review the efficacy of methylprednisolone versus dexamethasone in the management of postsurgical pain, swelling, and trismus after mandibular third molar surgery. Randomized, double-blinded studies from PubMed, CINAHL, Scopus, DOSS, Cochrane central, and Web of Science were identified by using a search strategy. Randomized controlled trials evaluating the efficacy of use of dexamethasone versus methylprednisolone for mandibular third molar extraction were only considered. The studies involving the use of any other corticosteroid agent were excluded. Outcomes assessed were postoperative pain, the number of rescue analgesics required, swelling, trismus, and adverse events. The search strategy yielded 1046 articles for title and abstract screening, out of which only seven studies were included in the systematic review after full text screening. There was considerable heterogeneity between the studies with regards to the method as well as the parameters assessed. Risk of bias was low in three studies and unclear in other four studies. On pooled analyses, there was no significant difference with respect to pain, rescue analgesics, and swelling in the test and the control group. Forest plot analysis showed that dexamethasone had lesser trismus in early postoperative period (postoperative day 2) as compared to methylprednisolone. None of the included studies reported any adverse effects. Both the corticosteroids have similar efficacy in reducing the postoperative pain and swelling; however, dexamethasone showed statistically significant difference from methylprednisolone in reducing trismus (estimated standardized mean difference of -0.69 mm; 95% CI: -1.01 to -0.38; < 0.0001) in the early postoperative period. However, due to statistical heterogeneity, quality of the evidence for the review was low to moderate. Hence, more studies with larger study sample and low risk of bias are needed to confirm these results.

Review
BACKGROUND
Obesity is a multifactorial chronic disease involving multiple organs, devices, and systems involving important changes in the stomatognathic system, such as in the orofacial muscles, temporomandibular joint, cheeks, nose, jaw, maxilla, oral cavity, lips, teeth, tongue, hard/soft palate, larynx, and pharynx. Patients with obesity indicated for bariatric surgery reportedly presented with abnormalities in the structures and function of the stomatognathic apparatus. This occurs through the accumulation of adipose tissue in the oral cavity and pharyngeal and laryngeal regions. Therefore, this systematic review aimed to elucidate the changes occurring in the stomatognathic system of patients with obesity after undergoing bariatric surgery.
METHOD
Information was searched based on the equations developed with the descriptors obtained in DECS and MESH using the PRISMA methodology. Studies published between 2010 and October 2021 in databases including PubMed, ProQuest, Scielo, Dialnet, EBSCO, and Springer Link were considered.
RESULTS
Eighty articles met the inclusion criteria after evaluating the articles, thereby allowing for the determination of the morphophysiological correlation of the stomatognathic system with the population studied. At the morphological or structural level, changes were observed in the face, nose, cheeks, maxilla, jaw, lips, oral cavity, teeth, tongue, palate, temporomandibular joint, neck, muscles, head, shoulders, larynx, and pharynx. At the morphological level, the main changes occurred in, and the most information was obtained from, the labial structures, teeth, muscles, pharynx, and larynx. Physiological changes were in breathing, phonation, chewing, and swallowing, thereby revealing the imbalance in basic and vital functions.
CONCLUSIONS
Analyzing the changes and structures of obese patients and candidates for bariatric surgery revealed that, in the preoperative period, the evidence is clear owing to the presence of a wide range of information. However, the information is more limited regarding the postoperative period; thus, further research focusing on characterization of the system postoperatively is warranted.

Meta-Analysis
Following liver transplant (LT), osteoporosis is a severe complication that causes morbidity. However, the incidence and risk factors of osteoporosis and fractures have not been well described. Single-arm meta-analysis of studies reporting osteopenia, osteoporosis, and fractures post-LT was performed with meta-regression for study period. Dichotomous variables, continuous variables and time-to-event variables were pooled in odds ratio, weighted mean difference and hazard ratio, respectively. For risk factors with limited data, a systematic review of literature was conducted. There was a significant increase in both osteoporosis and fractures compared to non-LT patients. Osteopenia, osteoporosis and incident fractures were newly diagnosed in 34.53% (CI: 0.17-0.56, n = 301), 11.68% (CI: 0.05-0.24, n = 1251) and 20.40% (CI: 0.13-0.30, n = 4322) of LT patients, respectively. Female gender (P = 0.017) increased risks of osteoporosis but not older age and BMI. Older age, lower pre-LT bone mineral density (BMD), presence of bone disease pre-LT were significant risk factors for fractures but not female gender, post-menopausal state, BMI, smoking and alcohol. There is a high incidence of skeletal complications post-LT. Older age, lower pre-LT BMD and presence of bone disease pre-LT are significant risk factors that are associated with incident fractures physicians should be cognisant of in liver transplant recipients.

Journal of the American Medical... Apr 2022To summarize the evidence for preoperative deprescribing and its effect on postoperative outcomes in older adults undergoing surgery. (Review)
Review
OBJECTIVE
To summarize the evidence for preoperative deprescribing and its effect on postoperative outcomes in older adults undergoing surgery.
DESIGN
Systematic review.
SETTING AND PARTICIPANTS
All available studies.
METHODS
We searched EMBASE, Cumulative Index of Nursing and Allied Health (CINAHL), and PubMed from inception to January 12, 2021. Settings included outpatient settings during the waiting period for surgery (ie, preoperative clinic) through to the preoperative period in the hospital. Participants who were older adults, aged ≥65 years, undergoing planned or emergency surgery with deprescribing or medication-related interventions were included for review.
RESULTS
We identified 3 different methods of deprescribing intervention delivery during the preoperative period: geriatrician-led (n = 2), interdisciplinary team-led (n = 8), and pharmacist-led (n = 6). Outcomes were related to health care utilization, patient outcomes, and medication changes; however, results were difficult to compare because of heterogeneous outcomes within the topics. Overall, results were either positive or neutral.
CONCLUSIONS AND IMPLICATIONS
The evidence for deprescribing during the preoperative period for older adults undergoing surgery is weak because of the heterogeneity of intervention delivery and outcomes, inclusion of nonoperative cases in some studies, and low power. This review highlights the need for future research, which may consider the following: (1) interdisciplinary approach, (2) coordination of deprescribing efforts with primary care provider from the waiting period for surgery up to after hospital discharge, and (3) validated deprescribing criteria such as STOPP/START that is easy to implement. It is important to note that results yielded positive and neutral results, not negative ones, which should reassure clinicians to implement deprescribing for older adults during the surgical period. Additionally, policy initiatives such as integrated electronic medical records or increased reimbursement of deprescribing efforts for primary care providers and/or hospitals should be pursued to prevent adverse postoperative events for this population.

Comparison of Clinical Outcomes and Complications Between Endoscopic and Minimally Invasive Transforaminal Lumbar Interbody Fusion for Lumbar Degenerative Diseases: A Systematic Review and Meta-analysis.
STUDY DESIGN
Systematic review and meta-analysis.
OBJECTIVE
Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) is a classic surgical procedure for the treatment of lumbar degenerative diseases (LDD). With the development of endoscopic technology, endoscopic transforaminal lumbar interbody fusion (Endo-TLIF) can also achieve adequate decompression and interbody fusion. However, whether Endo-TLIF is superior to MIS-TLIF has not been adequately studied. In this systematic review and meta-analysis, we aimed to evaluate the treatment difference between Endo-TLIF vs MIS-TLIF.
METHODS
We conducted a systematic review and meta-analysis of the studies to compare the clinical outcomes and complications associated with Endo-TLIF vs. MIS-TLIF for the treatment of LDD. A literature search was conducted using the PubMed, Embase, Cochrane Library and Scopus databases for studies published up to April 1, 2022. Both retrospective and prospective studies that compared between Endo-TLIF and MIS-TLIF were included.
RESULTS
A total of 8 studies involving 581 patients were finally included in this meta-analysis. Endo-TLIF significantly prolonged the operation time, but reduced the blood loss amount and length of hospital stay. Moreover, Endo-TLIF was superior to MIS-TLIF on relief of back pain and functional recovery in the early postoperative period. However, there were no significantly differences in long-term clinical outcomes, fusion rate and incidence of complications between Endo-TLIF and MIS-TLIF.
CONCLUSIONS
Endo-TLIF was similar to MIS-TLIF in the long-term clinical outcomes, fusion and complication rates. Endo-TLIF prolongs the operation time, but shortens the length of hospital stay, and has the advantages of less surgical trauma, less blood loss, faster recovery, and early postoperative back pain relief.

Review
Analgesic effect of ropivacaine combined with dexmedetomidine in the postoperative period in children undergoing ultrasound-guided single-shot sacral epidural block: A systematic review and meta-analysis.
OBJECTIVE
This study aims to evaluate the efficacy of dexmedetomidine as an adjuvant to ropivacaine in prolonging postoperative analgesia and reducing pain scores in children undergoing surgery.
METHODS
Five online databases were searched for RCTs on postoperative analgesia of pediatric patients undergoing ultrasound-guided single-shot sacral epidural block with dexmedetomidine as an adjuvant to ropivacaine up to January 2, 2023. Pain score and sedation score at 2, 4, 8, 12, and 24 h after the operation, the time of first receiving additional analgesic drugs, and the number of postoperative adverse effects were selected to compare the efficacy and safety of combined treatment with ropivacaine alone for pediatrics. The standard mean difference (SMD) or odds ratio (OR) and the corresponding 95% confidence interval (95%CI) were calculated by using a random-effects model.
RESULTS
A total of 295 articles were retrieved, but only 20 records were included in this meta-analysis. The results showed that dexmedetomidine combined with ropivacaine for sacral epidural block in children undergoing ultrasound-guided single-shot sacral epidural block had a more prolonged analgesia effect (SMD = 3.47, 95%CI: 2.80, 4.14). There were lower analgesia scores at 2 h(T), 4 h(T), 8 h(T), 12 h(T), and 24 h(T) in postoperative period ( : SMD = -1.02, 95%CI: -1.31, -0.72; : SMD = -1.02, 95%CI: -1.32, -0.72; : SMD = -0.84, 95%CI: -1.12, -0.56; : SMD = -0.61, 95%CI: -1.03, -0.20; : SMD = -1.03, 95%CI: -1.28, -0.78). And the incidence of adverse effects was similar between the two groups (OR = 0.84, 95%CI: 0.59, 1.18).
CONCLUSIONS
The results of this review and meta-analysis support that dexmedetomidine, as an adjuvant to ropivacaine, can improve postoperative analgesia of surgery and significantly prolong the analgesic time in children, with a similar incidence rate of adverse symptoms when compared with ropivacaine alone.

Review
Piezosurgery use has become increasingly prevalent in osteotomies. Piezoelectric ultrasound waves can cut bone effectively, and some studies have shown reduced post-operative morbidities compared to conventional osteotomies. Oedema and ecchymosis are common complications of rhinoplasty and can impact patient satisfaction, wound healing, and recovery. We aim to provide an up-to-date comparison of post-operative oedema and ecchymosis in piezosurgery and conventional osteotomies. A literature search was conducted using the following online libraries; Pubmed, Cochrane, Science Direct, and ISRCTN (International Standard Randomised Controlled Trial Number). English publications between 2015 and 2020 were included. A systematic review was completed, and a comparison of oedema and ecchymosis in piezosurgery and conventional osteotomies was examined alongside other outcomes such as pain, mucosal injury, and surgery time. Eight randomised controlled trials (RCTs) met our criteria with a combined total of 440 patients: 191 male and 249 female. Piezosurgery had statistically significant (p < 0.05) reduction in short-term oedema compared to conventional osteotomies in 75% of the papers included, and in 50% this persisted across the whole follow-up period. Similarly, ecchymosis scoring was initially statistically lower (p < 0.05) in piezosurgery in 87.5% of the RCTs, and in 75% this persisted across the whole follow-up period. A reduction in pain (p < 0.05) and mucosal injury (p < 0.05) was also seen in piezoelectric osteotomies. The length of surgery time varied. Piezoelectric osteotomies reduce oedema and ecchymosis compared to conventional osteotomies, in addition to improving pain and mucosal injury. However, disadvantages such as length of surgery time and cost have been reported. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

Review
AIM
To determine the advantages and disadvantages of both methods by comparing classic circumcision methods with circumcision methods assisted by ring instruments.
MATERIAL-METHODS
Only studies that compared open procedures and ring devices for male circumcision were included. A total of 6226 patients were examined in 14 studies. The methodological quality of RCT was evaluated using Cochrane collaboration's tools. The Review Manager software statistical package was used to analyze the ORs for dichotomous variables and the mean differences for continuous variables. The proportion of heterogeneity across the studies was tested using the I 2 index. Potential publication bias was assessed by identifying the presence of visual asymmetry/symmetry with funnel plot studies.
RESULTS
There were 1812 patients in the open circumcision group and 4414 patients in the ring groups. In total, there was no difference identified between the groups. The open procedure had an advantage compared to the Plastibell subgroup for hemorrhage, while in the other two subgroups, the ring instrument groups had the advantage. Statistically significant in favor of ring devices was found in operating time.There was no difference between the groups for early (postoperative) pain scores. For late-period pain scores, differences with statistical significance were identified in favor of ring devices both in subgroups and in total. For satisfaction, apart from one study in the PrePex group, statistical significance was obtained in favor of ring devices for the other subgroups and in total.
CONCLUSION
The main factors in favor of the use of ring instruments for circumcision are the short total surgical duration, not requiring advanced surgical experience, ease of learning and application, and patient relative satisfaction rates. However, it is a condition to know open circumcision methods and to have experience of this surgery for use in situations with hemorrhage complications, mainly, and without ring instruments of appropriate size.
