Review
Low back pain represents the leading cause of disability since 1990. In 90% of cases, it is classified as non-specific low back pain, being chronic in 10% of subjects. Ultrasound has proven to be an effective measurement tool to observe changes in the activity and morphology of the abdominal muscles. This article reviews which core synergies are studied with ultrasound in healthy subjects and with chronic non-specific low back pain. A systematic review was conducted on studies analyzing synergies between two or more core muscles. Publications from 2005 until July 2021 were identified by performing structured searched in Pubmed/MEDLINE, PEDro and WOS. Fifteen studies were eligible for the final systematic review. A total of 56% of the studies established synergies between the core muscles and 44% between the homo and contralateral sides of the core muscles. The most studied core synergies were transversus abdominis, internal oblique and external oblique followed by the rectus abdominis and the lumbar multifidus. No studies establishing synergies with diaphragm and pelvic floor were found. Eight studies were conducted in healthy subjects, five studies in subjects with chronic non-specific low back pain compared to healthy subjects and two studies in subjects with chronic non-specific low back pain.

Comparative Study Review
OBJECTIVES
The purpose of this systematic review is to present and compare results from studies that have been using autologous tissue for POP repair.
METHODS
Systematic review was done according to the Cochrane Handbook for Systematic Reviews. We aimed to retrieve reports of published and ongoing studies on the efficacy and safety of autologous tissue in vaginal vault prolapse repair. The databases searched were MEDLINE (PubMed interface), Scopus, Cohrane Central Register of Controlled Trials (CENTRAL) and ClinicalTrials.gov.
RESULTS
The success rate varied among studies. In fascia-lata group success rate reports varied from 83 to a 100%, with a median follow-up from 12 to 52 months among studies. Rectus fascia reported success rates from 87 to a 100% with a follow-up of 12 months to longest of 98 months.
CONCLUSION
Autologous tissues show satisfying outcomes in terms of safety and efficacy. Sacrocolpopexy procedure with fascia lata has better outcome in term of treatment of prolapse. Harvesting place on lateral side of buttock has more complications in comparison with rectus fascia but size of the graft can be wider in fascia-lata group.

Meta-Analysis
Bulge and hernia may occur after abdominally based breast reconstruction. The purpose of this study is to provide an estimate of the effects that the type of flap used for breast reconstruction (ie, transverse rectus abdominis muscle [TRAM] vs muscle-sparing [MS]-2 TRAM vs DIEP) has on the postoperative development of both abdominal bulge and abdominal hernia, taking into consideration the method of donor site closure (ie, with mesh vs without mesh), based on the available literature. Twenty-eight studies met the inclusion criteria and were included in the systematic review. From these, 9 studies were comparative and suitable for meta-analysis. The results showed that, for unilateral breast reconstructions, there was no statistically significant difference in hernia/bulge rates in the following techniques: MS-2 TRAM flap without mesh, MS-2 TRAM flap with mesh, and DIEP flap without mesh, and they showed significantly lower hernia/bulge rates compared with TRAM flap without mesh, and TRAM flap with mesh, whereas for bilateral reconstructions, there was no statistically significant difference in hernia/bulge rates in the following techniques: MS-2 TRAM flaps with mesh and DIEP flaps without mesh, and they showed significantly lower hernia/bulge rates compared with TRAM flaps without mesh, TRAM flaps with mesh, and MS-2 TRAM flaps without mesh.

Meta-Analysis
OBJECTIVE
Collection and meta-analysis of all relevant anatomical studies related to the pubic symphysis to provide a state of the art review of its musculotendinous and ligamentous attachments from 2010 to date.
METHODS
A systematic search of published literature databases (PubMed, Web of Science and Embase) was conducted according to the PRISMA guidelines from January 2010 up until now. All papers investigating the anatomy of the musculotendinous attachments of the pubis and the pubic ligaments were eligible. Methodological quality was assessed using the Quality Appraisal for Cadaveric Studies (QUACS scale). A narrative analysis approach was adopted to synthesize the findings.
RESULTS
After screening and review of 1313 papers, a total of six studies investigating the anatomy of the pubic ligaments and tendons were included. Of the six articles included in this systematic review, five articles performed a macroscopic anatomical dissection, three articles performed a microscopic (histological) study, and one article combined microscopic examination with an MRI imaging examination. The anatomy of the pubic symphysis was examined in 76 anatomical cadavers (60 embalmed, 16 fresh frozen). In total 44 male cadavers (58%), 28 female cadavers (37%) and four cadavers whose gender was not stated were dissected.
CONCLUSION
The age-old accepted concept of the fusion of the rectus abdominis with the adductor longus via the aponeurotic plate is outdated. New anatomical concepts like the pyramidalis-anterior pubic ligament-adductor longus complex (PLAC), recto-gracilis tendon, fusion of adductor brevis with gracilis, etc. are recently introduced. The awareness of anatomy and morphology of the pubic ligaments plays a significant role in understanding the diagnosis and treatment of groin pain.

Meta-Analysis
BACKGROUND
Anticipatory postural adjustments (APAs) are a feedforward mechanism triggered in advance to a predictable perturbation, to help the individual counteract mechanical effects that the disturbance may cause. Whether or not this strategy is compromised in the elderly is not a consensus in the literature.
METHODS
In this systematic review with meta-analysis, we investigated aging effects on postural control, based on anticipatory postural adjustments (APAs). We selected 11 eligible articles of the following databases: Lilacs, SciELO, PubMed, Cochrane Central, Embase, and CINAHL, involving 324 research participants, assessing their methodological quality and extracting electromyographic, posturographic, and kinematic measurements. We included studies that investigated the occurrence of APAs in healthy younger and older adults, published before 10th August 2022, in English. Studies involving participant with conditions that may affect balance or that did not report measures of onset or amplitude of electromyography (EMG), COP, or kinematics were excluded. To analyze the aggregated results from these studies, we performed the analysis based on the outcome measures (EMG, COP, or kinematic measures) used in individual studies. We calculated differences between younger and older adult groups as the mean differences between the groups and the estimated effect. Egger's test was conducted to evaluate whether this meta-analysis had publication bias.
RESULTS
Through this review, older adults showed no significant difference in the velocity to perform a movement compared to the younger adults (MD 0.95, 95% CI -0.86, 2.76, I = 82%), but both muscle onset and center of pressure (COP) onset were significantly more delayed in older than in younger adults: erector spinae (MD -31.44, 95% CI -61.79, -1.09, I = 95%); rectus abdominis (RA) (MD -31.51, 95% CI -70.58, -3.57, I = 85%); tibialis anterior (TA) (MD -44.70, 95% CI -94.30, 4.91, I = 63%); soleus (SOL) (MD -37.74, 95% CI -65.43, -10.05, I = 91%); gastrocnemius (GAS) (MD -120.59, 95% CI -206.70, -34.49, I = 94%); quadriceps (Q) (MD -17.42, 95% CI -34.73, -0.12, I = 0%); biceps femoris (BF) (MD -117.47, 95% CI -192.55, -42.70, I = 97%); COP onset (MD -45.28, 95% CI -89.57, -0.98, I = 93%), and COP apa (COPapa) (MD 2.35, 95% CI -0.09, 4.79, I = 64%). These changes did not seem to be linked to the speed of movement but possibly to age-related physiological changes that indicated decreased motor control during APAs in older adults.
CONCLUSIONS
Older adults use different postural strategies that aim to increase the safety margin and stabilize the body to perform the movement, according to the requirements imposed, and this should be considered in rehabilitation protocols.

Review
BACKGROUND
The aim of the present study was to evaluate the surgical technique, short-term oncological and perioperative outcomes for the transabdominal division of the levator ani muscles during abdominoperineal excision of the rectum (APER).
METHODS
A systematic review was performed to identify studies reporting on transabdominal division of the levator ani during APER. A comprehensive literature search was performed using a combination of free-text terms and controlled vocabulary when applicable on the following databases: MEDLINE, EMBASE, Science Citation Index Expanded and Cochrane Central Register of Controlled Trials in the Cochrane Library. The search period was from January 1945 to December 2015. The following search headings were used: "transabdominal", "transpelvic", "abdominal" or "pelvic" combined with either "levator" or "extralevator" and with "abdominoperineal".
RESULTS
Nine publications were identified reporting on 99 participants. The male/female distribution was 1.44:1, respectively, and the mean age was 56.6 (30-77) years. All tumours were less than 5 cm from the anal verge. The preoperative radiological staging was T2 in 18% of cases, T3 in 53.5% and T4 in 28.5%. Transabdominal division of the levators was performed laparoscopically in 55 cases, robotically in 34 and open in 10. The mean operating time was 255 (177-640) min. Mean intraoperative blood loss was 140 (92-500) ml. There were no conversions to open. Circumferential resection margins were positive in two cases, and there was one intraoperative perforation. Mean post-operative length of stay was 9.3 (3-67) days. Follow-up (from 0 to 31 months) revealed 19 perineal wound infections, 15 cases of sexual dysfunction and 7 cases of urinary retention. There was no mortality and 1 readmission.
CONCLUSIONS
Transabdominal division of the levators during APER is feasible and reproducible, with acceptable perioperative and good early oncological outcomes. Further comparative studies are needed.

BACKGROUND
Two main trends are described for the treatment of diastasis recti: plication versus midline mesh reinforcement. Indications for these procedures have not been clearly described. This study reviewed the outcomes in the treatment of rectus diastasis with plication versus mesh by the assessment of durability, complications, and patient-reported outcomes.
MATERIALS AND METHODS
A systematic review of literature on the treatment of diastasis recti was performed searching through PubMed, Embase, Web of Science, and Cochrane databases. This resulted in 53 eligible articles and predefined inclusion criteria led to the selection of 24 articles. Primary outcomes included recurrence and perioperative complications and secondary outcomes were defined as patient satisfaction, chronic pain, and quality of life.
RESULTS
A total of 931 patients were surgically treated for rectus divarication (age range: 18 - 70 years). The most frequently noted comorbidity was obesity and 10.6 percent were smokers. Recurrence was reported in 5 percent of the patients. The most frequent complication was seroma (7 percent), followed by abdominal hypoesthesia (6 percent), and surgical site infection (2 percent). Chronic pain was reported in 4 percent of the patients. Satisfaction was assessed subjectively in the majority of patients and was generally rated as high. Follow-up period ranged from 3 weeks to 20 years.
CONCLUSIONS
Durability, safety, and high patient satisfaction support surgical correction of rectus diastasis and could not favor a treatment method. Inter-rectus distance could not be identified as the indicator for technique, which emphasizes that other factors might add to the entity of abdominal wall protrusion more than previously thought.

BACKGROUND.
Safe and efficacious modalities of perioperative analgesia are essential for enhanced recovery after surgery. Truncal nerve blocks are one potential adjunct for analgesia of the abdominal wall, and in recent years their popularity has increased. Transversus abdominis plane block (TAPB) and rectus sheath block (RSB) have been shown to reduce morphine consumption and improve pain relief after abdominal surgery. These blocks typically require large volumes of local anaesthetic (LA). We aimed to synthesize studies evaluating systemic concentrations of LA after perioperative TAP and RSB to enhance our understanding of systemic LA absorption and the risk of systemic toxicity.
METHODS.
An independent literature review was performed in accordance with the methods outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. An electronic search of four databases (MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and PubMed) was conducted. Primary articles measuring systemic concentrations of LA after single-shot bolus TAPB or RSB were included.
RESULTS.
Fifteen studies met the inclusion criteria. Rapid systemic LA absorption was observed in all studies. Of a total of 381 patients, mean peak concentrations of LA exceeded toxic thresholds in 33 patients, of whom three reported mild adverse effects. The addition of epinephrine reduced systemic absorption of LA. No instances of seizure or cardiac instability were observed.
CONCLUSIONS.
Local anaesthetic in TAPB and RSB can lead to detectable systemic concentrations that exceed commonly accepted thresholds of LA systemic toxicity. Our study highlights that these techniques are relatively safe with regard to LA systemic toxicity.

BACKGROUND
Transversus abdominis release (TAR), as a type of posterior component separation, is a new myofascial release technique in complex ventral hernia repair. TAR preserves rectus muscle innervation, creates an immense retromuscular plane and allows bilaminar ingrowth of the mesh. The place of the TAR within the range of established anterior component separation techniques (CST) is unclear. Aim of this systematic literature review is to estimate the position of the TAR in the scope of ventral hernia repair techniques.
METHODS
MEDLINE, Embase, Pubmed and the Cochrane controlled trials register and Science citation index were searched using the following terms: 'posterior component separation', 'transversus abdominis release', 'ventral hernia repair', 'complex abdominal wall reconstruction'. To prevent duplication bias, only studies with a unique cohort of patients who underwent transversus abdominis release for complex abdominal wall reconstruction were eligible. Postoperative complications and recurrences had to be registered adequately. The rate of surgical site occurrences and recurrences of the TAR were compared with those after anterior CST, published earlier in two meta-analyses.
RESULTS
Five articles met our strict inclusion criteria, describing 646 TAR patients. Methodological quality per study was good. Mean hernia surface was 509 cm and 88% of the hernias were located in the midline. Preoperative risk stratification was distributed in low risk (10%), co-morbid (55%), potentially contaminated (32%) and infected (3%). Pooled calculations demonstrated a mean SSO rate of 15% after TAR (20-35% after anterior CST) and a mean 2-year hernia recurrence rate of 4% (13% after anterior CST). Mean hernia surface was 300 cm in anterior component separation studies.
CONCLUSION
This review demonstrates that the transversus abdominis release is a good alternative for anterior CST in terms of SSO and recurrence, especially in very large midline ventral hernias.

Meta-Analysis
BACKGROUND
Different regional anesthesia (RA) techniques have been used for laparoscopic cholecystectomy (LC), but there is no consensus on their comparative effectiveness. Our objective was to evaluate the effect of RA techniques on patients undergoing LC using a network meta-analysis approach.
METHODS
We conducted a systematic review and network meta-analysis. We searched PubMed, the Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, and Web of Science (Science and Social Science Citation Index) using the following PICOS criteria: (P) adult patients undergoing LC; (I) any RA single-shot technique with injection of local anesthetics; (C) placebo or no intervention; (O) postoperative opioid consumption expressed as morphine milligram equivalents (MME), rest pain at 12 h and 24 h post-operation, postoperative nausea and vomiting (PONV), length of stay; and (S) randomized controlled trials.
RESULTS
A total of 84 studies were included. With the exception of the rectus sheath block (P = 0.301), the RA techniques were superior to placebo at reducing opioid consumption. Regarding postoperative pain, the transversus abdominis plane (TAP) block (-1.80 on an 11-point pain scale) and erector spinae plane (ESP) block (-1.33 on an 11-point pain scale) were the most effective at 12 and 24 h. The TAP block was also associated with the greatest reduction in PONV.
CONCLUSIONS
RA techniques are effective at reducing intraoperative opioid use, postoperative pain, and PONV in patients undergoing LC. Patients benefit the most from the bilateral paravertebral, ESP, quadratus lumborum, and TAP blocks.
