Randomized Controlled Trial
BACKGROUND
Splenectomy performed with a curved incision results in severe postoperative pain. The aim of this study was to evaluate the effect of transversus abdominis plane block and rectus sheath block on postoperative pain relief and recovery.
METHODS
A total of 150 patients were randomized into the control (C), levobupivacaine (L) and levobupivacaine/morphine (LM) groups. The patients in the C group received only patient-controlled analgesia. The patients in the L and LM groups received transversus abdominis plane block and rectus sheath block with levobupivacaine or levobupivacaine plus morphine. The intraoperative opioid consumption; postoperative pain score; time to first analgesic use; postoperative recovery data, including the times of first exhaust, defecation, oral intake and off-bed activity; the incidence of postoperative nausea and vomiting and antiemetics use; and the satisfaction score were recorded.
RESULTS
Transversus abdominis plane block and rectus sheath block reduced intraoperative opioid consumption. The patients in the LM group showed lower postoperative pain scores, opioid consumption, postoperative nausea and vomiting incidence and antiemetic use and presented shorter recovery times and higher satisfaction scores.
CONCLUSIONS
The combination of transversus abdominis plane block and rectus sheath block with levobupivacaine and morphine can improve postoperative pain relief, reduce the consumption of analgesics, and partly accelerate postoperative recovery.

Transcriptomic Profiling of Rectus Abdominis Muscle in Women with Gestational Diabetes-Induced Myopathy: Characterization of Pathophysiology and Potential Muscle Biomarkers of Pregnancy-Specific Urinary Incontinence.
Gestational diabetes mellitus (GDM) is recognized as a "window of opportunity" for the future prediction of such complications as type 2 diabetes mellitus and pelvic floor muscle disorders, including urinary incontinence and genitourinary dysfunction. Translational studies have reported that pelvic floor muscle disorders are due to a GDM-induced-myopathy (GDiM) of the pelvic floor muscle and rectus abdominis muscle (RAM). We now describe the transcriptome profiling of the RAM obtained by Cesarean section from GDM and non-GDM women with and without pregnancy-specific urinary incontinence (PSUI). We identified 650 genes in total, and the differentially expressed genes were defined by comparing three control groups to the GDM with PSUI group (GDiM). Enrichment analysis showed that GDM with PSUI was associated with decreased gene expression related to muscle structure and muscle protein synthesis, the reduced ability of muscle fibers to ameliorate muscle damage, and the altered the maintenance and generation of energy through glycogenesis. Potential genetic muscle biomarkers were validated by RT-PCR, and their relationship to the pathophysiology of the disease was verified. These findings help elucidate the molecular mechanisms of GDiM and will promote the development of innovative interventions to prevent and treat complications such as post-GDM urinary incontinence.

Few studies have assessed the efficacy and safety of reconstruction of sternal infection using a pectoralis muscle flap combined with a rectus abdominis muscle (RAM) sheath fasciocutaneous flap. We report here our experience with this procedure to reconstruct the sternal defect in patients (n = 46) with a deep sternal wound infection (DSWI) after cardiac surgery. After wound reconstruction, the proportion of prolonged mechanical ventilation use and intensive care unit (ICU) stay were 17.4% (n = 8) and 21.7% (n = 10), respectively. The 30-day all-cause mortality was 15.2%; recurrence rate was 17.4%; postoperative complications were 15.2%; and median hospital stay was 31 (0-157) days. Multivariate logistic regression analysis revealed that hypertension (β = 21.32, 95%CI 4.955-37.68, P = .014), drainage-tube use (β = 0.944, 95%CI 0.273-1.614, P = .008), and prolonged intensive care unit stay (β = 53.65, 95%CI 31.353-75.938, P < .001) were significantly correlated with hospital stay. In conclusion, a procedure including surgical debridement, sternal reconstruction with bilateral PM and RAM sheath flap, long-term antibiotics, and adequate drainage is a beneficial technique in the reconstruction of deep sternal wound infection after cardiac surgery. Duration of drainage tube use may be as an index for a hospital stay or wound healing.

Review
INTRODUCTION
Perineal defects are commonly encountered in an oncological setting although they may also present as a result of trauma and infection (eg following Fournier's gangrene). Reconstruction of these poses functional as well as aesthetic challenges. Skin coverage and tissue volume may both be required in addition to anogenital preservation or reconstruction. General prerequisites of an adequate reconstruction of perineal defects include provision of skin cover, well vascularised tissue to fill the dead space (reducing fluid collection and infection), vulvovaginal reconstruction and no faecal or urinary contamination.
METHODS
A literature search was performed using PubMed and MEDLINE ® . The search terms included 'perineal defects', 'perineal reconstruction', 'perforator flaps for perineum', 'vulval flaps', 'secondary healing of wound' and 'vacuum assisted closure'. Backward chaining of reference lists from retrieved papers was also used to expand the search.
FINDINGS
Modern developments have led to an increased expectation in improved quality of life as the main goal of reconstruction, therefore necessitating surgery with less morbidity and early return to normal activity. Progress in microsurgical procedures has been the main recent advance in perineal reconstruction and, in future, refinements in perforator flap design and tissue engineering techniques will lead to even better reconstructions.

RATIONALE AND OBJECTIVES
The rectus abdominis muscle exhibits early and significant muscle atrophy, which has largely been characterized using ultrasound measured muscle thickness. However, the validity of rectus abdominis muscle thickness as a metric of muscle size has not been established, limiting precise interpretation of age-related changes. In a heterogeneous cohort of women and men, our objectives were to: (1) evaluate the association between rectus abdominis muscle thickness and cross-sectional area (CSA), and (2) examine if the visceral adipose tissue (VAT) compartment confounds the validity of rectus abdominis muscle thickness.
MATERIALS AND METHODS
Abdominal computed tomography scans of the third lumbar vertebrae from clinical and healthy populations were used to evaluate rectus abdominis thickness and CSA, and VAT CSA. Computed tomography scans were utilized due to the limited field of view of ultrasound imaging to capture the rectus abdominis CSA.
RESULTS
A total of 348 individuals (31% women) were included in this analysis, with a mean ± standard deviation age and body mass index of 51.2 ± 15.4 years and 28.0 ± 5.1 kg/m, respectively. Significant correlations were observed between rectus abdominis thickness and CSA for women (r = 0.758; p < 0.001) and men (r = 0.688; p < 0.001). Independent of age, VAT CSA was negatively associated with rectus abdominis thickness in men (p = 0.011), but not women (p = 0.446).
CONCLUSION
These data support the use of rectus abdominis muscle thickness as a measurement of muscle size in both women and men; however, the VAT compartment may confound its validity to a minor extent in men.

OBJECTIVE
To explore the surgical technique, effectiveness, and safety of muscle-sparing rectus abdominis myocutaneous flap vascularized with intercostal artery perforator and inferior epigastric artery perforator for breast reconstruction.
METHODS
Between December 2016 and February 2019, 6 cases of early breast cancer received modified radical surgery, lower abdominal flap was applied for one- or two-staged breast reconstruction. The average age of the patients was 34.6 years (range, 29-56 years). The disease duration ranged from 2 to 16 months, with an average of 9.5 months. The tumor was located in the upper outer quadrant in 4 cases and the lower outer quadrant in 2 cases. Pathological examination showed that they were all invasive ductal carcinoma. Four cases of breast cancer were in stage Ⅰ and 2 cases was in stage Ⅱ. During operation, the inferior epigastric artery perforators were found to be close to the upper edge of the flap and/or near the umbilical cord in 4 cases, the inferior epigastric artery perforator vessels were relatively small (<0.3 mm) in 2 cases; and the breast was reconstructed with muscle-sparing rectus abdominis myocutaneous flap vascularized with intercostal artery perforator and inferior epigastric artery perforator. The length, width, and thickness of the flap were (28.9±0.2), (12.1±0.4), and (4.4±0.3) cm, respectively. The length of the vascular pedicle was (11.5±0.2) cm and the weight of the flap was (420.5±32.7) g.
RESULTS
All 6 muscle-sparing rectus abdominis myocutaneous flaps were successful, and the breast incisions healed by first intention. There was no vascular crisis, donor site effusion, hematoma, or infection. All 6 patients were followed up 12-36 months (mean, 26.8 months). The reconstructed breast had a good shape, good elasticity, and no flap contracture or deformation; only linear scars left at the donor site of the flap, and the abdominal wall function was not affected. During follow-up, there was no breast cancer recurrence and metastasis.
CONCLUSION
When the inferior epigastric artery perforators are too close to the upper edge of the flap and/or near the umbilical cord, the vascularity of lower abdominal flap can be ruined, harvested in form of muscle-sparing rectus abdominis myocutaneous flap vascularized with intercostal artery perforator and inferior epigastric artery perforator can efficiently ensure blood supply safety.

Perineal wound complications after vertical rectus abdominis myocutaneous flap and mesh closure following abdominoperineal surgery and pelvic exenteration of anal and rectal cancers: A meta-analysis.
A meta-analysis research was implemented to appraise the perineal wound complications (PWCs) after vertical rectus abdominis myocutaneous (VRAM) flap and mesh closure (MC) following abdominoperineal surgery (AS) and pelvic exenteration (PE) of anal and rectal cancers. Inclusive literature research till April 2023 was done and 2008 interconnected researches were revised. Of the 20 picked researches, enclosed 2972 AS and PE of anal and rectal cancers persons were in the utilized researchers' starting point, 1216 of them were utilizing VRAM flap, and 1756 were primary closure (PC). Odds ratio (OR) and 95% confidence intervals (CIs) were utilized to appraise the consequence of VRAM flap in treating AS and PE of anal and rectal cancers by the dichotomous approach and a fixed or random model. VRAM flap had significantly lower PWCs (OR, 0.64; 95% CI, 0.42-0.98, p < 0.001), and major PWCs (OR, 0.50; 95% CI, 0.32-0.80, p = 0.004) compared to PC in AS and PE of anal and rectal cancers persons. However, VRAM flap and PC had no significant difference in minor PWCs (OR, 1; 95% CI, 0.54-1.85, p = 1.00) in AS and PE of anal and rectal cancer persons. VRAM flap had significantly lower PWCs, and major PWCs, however, no significant difference was found in minor PWCs compared to PC in AS and PE of anal and rectal cancers persons. However, caution needs to be taken when interacting with its values since there was a low sample size of most of the chosen research found for the comparisons in the meta-analysis.

A side-to-side difference in the muscle size of the rectus abdominis has been suggested to increase the strain injury risk. Attenuating the difference in size of the rectus abdominis may decrease the injury risk. To explore ways to highly activate one side of the rectus abdominis, we aimed to clarify the activity levels of both sides of the muscle during asymmetric abdominal exercises. Fifteen male sprinters performed the following five asymmetric exercises for the right and left sides: (i) sit-up twist, (ii) oblique leg raise, (iii) side bridge, (iv) side bridge roll out with the elbow, and (v) side bridge roll out with the foot. Side bridge roll out with the elbow and that with the foot were performed using a wheeled platform. During the exercises, electromyographic signals were recorded bilaterally from the upper, central, and lower portions of the rectus abdominis. We calculated the root mean square of electromyograms during the concentric and eccentric phases of the exercises and normalized to that during maximal voluntary contractions. In all portions of the rectus abdominis, the root mean squares of electromyograms were significantly higher in the moving side than in the non-moving side during the concentric and eccentric phases of the side bridge, the side bridge roll out with the elbow and that with the foot (all < 0.01), but not in sit-up twist or oblique leg raise. The root mean squares of electromyograms of all portions of the rectus abdominis in the moving side were significantly higher in the side bridge roll out with the elbow and that with the foot than in the side bridge during both phases (all < 0.01). The results suggest that the application of the wheeled platform to side bridge is useful to highly activate one side of the rectus abdominis.

PURPOSE
Meshes clearly have improved outcomes for tissue approximation over suture repairs for incisional hernias. A knowledge gap exists as to the surgical complication rate and post-operative outcomes of a mesh rectus diastasis repair with a narrow well-fixed mesh that simultaneously narrows the rectus muscles and closes the widened linea alba.
METHODS
Inclusion criteria for mesh abdominoplasty were patients who (1) underwent a retrorectus planar mesh for repair of rectus diastasis (2) did not have a concurrent incisional hernia and (3) underwent skin tailoring as part of a cosmetic aspect of their care. The primary endpoint was surgical site occurrence (SSO) at any time after surgery as determined with review of their office and hospital medical records. Secondary endpoints included the length and complexity of the return to the operating room for any reason, non-surgical complications, readmission, post-operative recovery, surgical site infection, recurrence/persistence of abdominal wall laxity, and soft tissue revision rates.
RESULTS
SSO rate was 0% for the 56 patients who underwent this procedure. There were 40 women and 16 men. Superficial infections requiring oral antibiotics were required in three patients. One was a drain site erythema, one was for a superficial stitch abscess, and the third was for a mesh strip knot infection 6 months after the procedure. One patient underwent further tightening of the abdominal wall. Rates of soft tissue revision in the office for improved cosmesis were 23% in women and 6% in men.
CONCLUSION
Repair of rectus diastasis with a narrow well-fixed mesh and concurrent skin abdominoplasty is a well-tolerated and reliable procedure with low recurrence and low SSO in the manner described. It is a procedure that works for both female and male pattern rectus diastasis, and has become our procedure of choice for moderate and severe rectus diastasis.

BACKGROUND
An important variability of contractile and metabolic properties between muscles has been highlighted. In the literature, the majority of studies on beef sensorial quality concerns M. longissimus thoracis. M. rectus abdominis (RA) is easy to sample without huge carcass depreciation and may appear as an alternative to M. longissimus thoracis for fast and routine physicochemical analysis. It was considered interesting to assess the muscle fibres of M. rectus abdominis in comparison with M. longissimus thoracis (LT) and M. triceps brachii (TB) on the basis of metabolic and contractile properties, area and myosin heavy chain isoforms (MyHC) proportions. Immuno-histochemical, histochemical, histological and enzymological techniques were used. This research concerned two populations of Charolais cattle: RA was compared to TB in a population of 19 steers while RA was compared to LT in a population of 153 heifers.
RESULTS
RA muscle had higher mean fibre areas (3350 microm(2) vs 2142 to 2639 microm(2)) than the two other muscles. In RA muscle, the slow-oxidative fibres were the largest (3957 microm(2)) and the fast-glycolytic the smallest (2868 microm(2)). The reverse was observed in TB muscle (1725 and 2436 microm(2) respectively). In RA muscle, the distinction between fast-oxidative-glycolytic and fast-glycolytic fibres appeared difficult or impossible to establish, unlike in the other muscles. Consequently the classification based on ATPase and SDH activities seemed inappropriate, since the FOG fibres presented rather low SDH activity in this muscle in comparison to the other muscles of the carcass. RA muscle had a higher proportion of I fibres than TB and LT muscles, balanced by a lower proportion either of IIX fibres (in comparison to TB muscle) or of IIA fibres (in comparison to LT muscle). However, both oxidative and glycolytic enzyme activities were lower in RA than in TB muscle, although the LDH/ICDH ratio was higher in RA muscle (522 vs 340). Oxidative enzyme activities were higher in RA than in LT muscle, whereas glycolytic enzyme activity was lower. In RA muscle, contractile and metabolic properties appeared to be less well-correlated than in the two other muscles.
CONCLUSIONS
RA muscle has some particularities in comparison to the LT and TB muscles, especially concerning the unusual large cross-section surface of SO fibres and the very low oxidative activity of intermediate IIA fibres.
