Analgesic effect of ultrasound-guided transversus abdominis plane block with or without rectus sheath block in laparoscopic cholecystectomy: a randomized, controlled trial.

BACKGROUND: Ultrasound-guided transversus abdominis plane (TAP) block is commonly used for pain control in laparoscopic cholecystectomy. However, significant pain persists, affecting patient recovery and sleep quality on the day of surgery. We compared the analgesic effect of ultrasound-guided TAP block with or without rectus sheath (RS) block in patients undergoing laparoscopic cholecystectomy using the visual analog scale (VAS) scores. METHODS: The study was registered before patient enrollment at the Clinical Research Information Service (registration number: KCT0006468, 19/08/2021). 88 American Society of Anesthesiologist physical status I-III patients undergoing laparoscopic cholecystectomy were divided into two groups. RS-TAP group received right lateral and right subcostal TAP block, and RS block with 0.2% ropivacaine (30 mL); Bi-TAP group received bilateral and right subcostal TAP block with same amount of ropivacaine. The primary outcome was visual analogue scale (VAS) for 48 h postoperatively. Secondary outcomes included the use of rescue analgesics, cumulative intravenous patient-controlled analgesia (IV-PCA) consumption, patient satisfaction, sleep quality, and incidence of adverse events. RESULTS: There was no significant difference in VAS score between two groups for 48 h postoperatively. We found no difference between the groups in any of the secondary outcomes: the use of rescue analgesics, consumption of IV-PCA, patient satisfaction with postoperative pain control, sleep quality, and the incidence of postoperative adverse events. CONCLUSION: Both RS-TAP and Bi-TAP blocks provided clinically acceptable pain control in patients undergoing laparoscopic cholecystectomy, although there was no significant difference between two combination blocks in postoperative analgesia or sleep quality.

The value of microvascular breast reconstruction: Cost equivalence of TRAM and DIEP flaps implications in the era of CMS reforms.

BACKGROUND: Recent CMS billing changes have raised concerns about insurance coverage for deep inferior epigastric perforator (DIEP) flap breast reconstruction. This study compared the costs and utilization of transverse rectus abdominis myocutaneous (TRAM), DIEP, and latissimus dorsi (LD) flaps in breast reconstruction. METHOD: The study utilized the National Inpatient Sample database to identify female patients who underwent DIEP, TRAM, and LD flap procedures from 2016 to 2019. Key data such as patient demographics, length of stay, complications, and costs (adjusted to 2021 USD) were analyzed, focusing on differences across the flap types. RESULTS: A total of 17,770 weighted patient encounters were identified, with the median age being 51. The majority underwent DIEP flaps (73.5%), followed by TRAM (14.2%) and LD (12.1%) flaps. The findings revealed that DIEP and TRAM flaps had a similar length of stay (LOS), while LD flaps typically had a shorter LOS. The total hospital charges to costs using cost-to-charge ratio were also comparable between DIEP and TRAM flaps, whereas LD flaps were significantly less expensive. Factors such as income quartile, primary payer of hospitalization, and geographic region significantly influenced flap choice. CONCLUSION: The study's results appear to contradict the prevailing notion that TRAM flaps are more cost-effective than DIEP flaps. The total hospital charges to costs using cost-to-charge ratio and hospital stays associated with TRAM and DIEP flaps were found to be similar. These findings suggest that changes in the insurance landscape, which may limit the use of DIEP flaps, could undermine patient autonomy while not necessarily reducing healthcare costs. Such policy shifts could favor less costly options like the LD flap, potentially altering the landscape of microvascular breast reconstruction.

Mothers' experiences living with diastasis recti abdominis - an interview study.

BACKGROUND: Diastasis recti abdominis (DRA) is a common postpartum condition. Knowledge is scarce on how mothers perceive living with DRA. The interaction between healthcare providers and patients plays a significant role in shaping the healthcare service experience. Women suffering from typical women's diseases tend to experience not being taken seriously or listened to when seeking healthcare. The aim of this study was to explore mothers' experiences living with DRA. METHODS: Semi-structured individual interviews were conducted with six Norwegian mothers, age 32-41, presenting with a clinically significant DRA. Topics discussed were how the condition is experienced, how it affects different aspects of day-to-day life and experiences with healthcare services. The data was analyzed using systematic text condensation. RESULTS: DRA had an impact on everyday life among the mothers included in this study. Three major themes emerged: (I) The path to obtaining knowledge and understanding of DRA, (II) DRA - intertwined with health issues and physical limitations and (III) A changed belly - on self-image & social interactions. The mothers experienced uncertainties and frustration when trying to learn about DRA. The limited knowledge of the condition made it hard to differentiate if the experienced symptoms were caused by presence of DRA or from other health issues. Several mothers felt misunderstood. CONCLUSION: DRA is a multifaceted condition affecting many aspects of day-to-day life in various dimensions, like physical, emotional, and social. This study contributes to a wider understanding of living with DRA, which might guide healthcare professionals in providing support for mothers with this condition.

Variations in abdominal muscle activities of obese females during abdominal bracing exercise in different body positions.

AIMS: This study evaluated the activities of the Rectus Abdominis (RA) and Transversus Abdominis (TrA) muscles during abdominal bracing exercises (ABE) in different body positions. METHODOLOGY: Electrical activities of both components of the RA and TrA muscles were assessed respectively in 25 obese females via surface electromyography during ABE in four (4) different body positions (crook lying, side lying, standing, and sitting). Each trial lasted for five (5) seconds with an hour rest period between trials. RESULTS: Electrical activities of each of the right RA (p = 0.008) and TrA (p = 0.001) muscles significantly varied across the four trials. For the left components of the RA (p = 0.243) and TrA (p = 0.332) muscles, no significant differences were observed across trials. The highest muscular activities were recorded during the standing trial while the crook lying position resulted in the least muscular activities. CONCLUSION: For the best results, abdominal bracing exercises should be performed in a standing position. The efficacy of adopting these body positions for long-term rehabilitation purposes should be investigated in future studies.

Complications associated with loop ileostomy: analysis of risk factors.

BACKGROUND: Loop ileostomy is a common surgical procedure but is associated with complications such as outlet obstruction (OO), parastomal hernia (PH), and high-output stoma (HOS). This study aimed to identify risk factors for these complications, as well as their causal relationships. METHODS: The study included 188 consecutive patients who underwent loop ileostomy between April 2016 and September 2021. Clinical factors and postoperative stoma-related complications (OO, HOS, and PH) were analyzed retrospectively. Stoma-related factors were evaluated using specific measurements from computed tomography (CT) scans. The incidence, clinical course, and risk factors for the stoma-related complications were investigated. RESULTS: OO was diagnosed in 28 cases (15.7%), PH in 60 (32%), and HOS in 57 (31.8%). A small longitudinal stoma diameter at the rectus abdominis level on CT and a right-sided stoma were significantly associated with OO. Creation of an ileostomy for anastomotic leakage was independently associated with HOS. Higher body weight and a large longitudinal stoma diameter at the rectus abdominis level on CT were significantly associated with PH. There was a significant relationship between the occurrence of OO and HOS. However, the association between OO and PH was marginal. CONCLUSION: This study identified key risk factors for OO, HOS, and PH as complications of loop ileostomy and their causal relationships. Our findings provide insights that may guide the prevention and management of complications related to loop ileostomy.

Short- and long-term morbidity after Taylor flap (oblique rectus abdominis flap) for perineal reconstruction after abdominoperineal resection: A single-center series of 140 patients.

BACKGROUND: Abdominoperineal resection (APR) leads to a substantial loss of tissue and a high rate of complications. The Taylor flap is a musculocutaneous flap used in reconstruction after APR. OBJECTIVES: We aimed to analyze the short and long-term morbidity of reconstruction with a Taylor flap (oblique rectus abdominis flap) after APR and to identify the risk factors for postoperative complications. METHODS: We retrospectively included all patients who had undergone APR with immediate reconstruction with a Taylor flap in our department between July 2000 and June 2018. Demographics, oncological data, treatment, and short- and long-term morbidity were reviewed. RESULTS: Among the 140 patients included, we identified early minor complications in 42 patients (30%) and 14 early major complications (10%). Total necrosis of the flap requiring its removal occurred in four patients (2.8%). Eleven patients (7.9%) presented with a midline incision hernia, and seven (5%) presented with a subcostal incision hernia. No perineal hernia was found. No risk factors for the complications were identified. CONCLUSION: The Taylor flap is a safe procedure with few complications and limited donor site morbidity. Moreover, it prevents perineal hernias. These results confirm that the Taylor flap is a well-suited procedure for reconstruction after APR.

Comparison between fascia lata and rectus fascia in treatment of pelvic organ prolapse: a systematic 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.

"Slim-Mesh" Technique for Diastasis Recti Abdominis, Including Obesity-Related Cases.

Background and Objective: We operated on a series of mostly obese patients with diastasis recti abdominis using the "Slim-Mesh" technique to repair/reinforce the diastasis and linea alba/recti muscles without plicating and traumatizing them. Additional objectives were to decrease operation time and intra- and postoperative complications. Methods: We considered T1 cases diastasis after pregnancy and T2 cases obesity (BMI ≥ 30 mg/kg2); D1, D2, and D3 when the diastasis measured 2-3, 3-5, and ≥ 5 cm, respectively; H0 and H1 without and concomitant umbilical and/or epigastric hernia, respectively. At our Department, between May 2010 and November 2022, 47 patients with diastasis recti were operated on with the "Slim-Mesh" technique to reinforce/repair the traumatized linea alba/recti muscles, without plicating them. This was a prospective (83%)-retrospective study. Results: We studied 23 males and 24 females. Mean age and BMI was 58 years and 29 kg/m2, respectively. Groups D1, D2, and D3 comprised 6, 23 and 18 patients, respectively; groups T1, T2, H0 and H1 comprised 22, 25, 13 and 34 patients, respectively. Mean operation time for all cases was 100 minutes. Mean length of hospital stay was 2.3 days and follow-up time was 5 years. We had 6 late postoperative complications: 3 hernia recurrences and 3 trocar site hernias. Conclusion: Considering the lack of agreement on the best surgery for diastasis recti abdominis repair, in our experience the "Slim-Mesh" technique is a valid, safe and easy-to-reproduce way to save, repair and reinforce linea alba/recti muscles in diastasis recti patients, including the obese population (53%).

Continuing Insurance Coverage for Flap-Based Breast Reconstruction: Is There a Reservation Cost Related to a Woman's Abdominal Flap Choice?

BACKGROUND: The recent proposed alterations to the Centers for Medicare and Medicaid Services regulations, although subsequently reversed on August 21, 2023, have engendered persistent concerns regarding the impact of insurance policies on breast reconstruction procedures coverage. This study aimed to identify factors that would influence women's preferences regarding autologous breast reconstruction to better understand the possible consequences of these coverage changes. METHODS: A survey of adult women in the United States was conducted via Amazon Mechanical Turk to assess patient preferences for breast reconstruction options, specifically deep inferior epigastric perforator (DIEP) and transverse rectus abdominis myocutaneous (TRAM) flap surgery. The Cochrane-Armitage test evaluated trends in flap preferences concerning incremental out-of-pocket payment increases. RESULTS: Of 500 total responses, 485 were completed and correctly answered a verification question to ensure adequate attention to the survey, with respondents having a median (interquartile range) age of 26 (25-39) years. When presented with the advantages and disadvantages of DIEP versus TRAM flaps, 78% of respondents preferred DIEP; however, as DIEP's out-of-pocket price incrementally rose, more respondents favored the cheaper TRAM option, with $3804 being the "indifference point" where preferences for both procedures converged (P < 0.001). Notably, respondents with a personal history of breast reconstruction showed a higher preference for DIEP, even at a $10,000 out-of-pocket cost (P = 0.04). CONCLUSIONS: Out-of-pocket cost can significantly influence women's choices for breast reconstruction. These findings encourage a reevaluation of emergent insurance practices that could potentially increase out-of-pocket costs associated with DIEP flaps, to prevent cost from decreasing equitable patient access to most current reconstructive options.

The Hypoechoic Triangle: A New Sonographic Landmark for Rectus Sheath Block.

Rectus sheath blocks can provide analgesia for upper abdominal midline incisions. These blocks can be placed on patients who are anticoagulated, supine, and under general anesthesia. However, block success rates remain low, presumably because of the difficulty of placing local anesthetic between the correct fascial layers. Here we characterize a hypoechoic triangle with sonography, an anatomic space between adjacent rectus abdominis segments that can be accessed for easier needle tip and catheter placement. This approach could reduce reliance on hydrodissection to correctly identify the potential space and instead improve block efficacy by offering providers a discrete target for local anesthesia.

The Relationship between Abdominal Diastasis and Lumbar Pain Pressure Threshold in Women Who Have Given Birth between the Ages of 30 and 45 Years-An Observational Pilot Study.

Background and Objectives: Current evidence confirms that the magnitude of the inter-rectus distance (IRD) is associated with the severity of abdominal pain. Furthermore, evidence exists in the literature about the impact abdominal muscles have on low back pain, lumbopelvic pain, breathing and lumbar abdominal strength; however, no studies analysing the level of association between abdominal diastasis and lumbar pain pressure threshold (PPT) exist. The aim of this study was to analyse the level of association between the rectus abdominis distance and pain pressure threshold in the lumbar spinous processes in women who have given birth between the ages of 30 and 45 years. Secondly, it was to study the level of association between the time elapsed since the last delivery and low back pain in women who have given birth between 30 and 45 years of age. Material and Methods: This was a pilot observational study in which 21 females participated. The abdominal diastasis was measured by ultrasound, the pain pressure threshold was assessed by an algometer and the pain perception by the Mc Gill questionnaire. Results: There was no significant relationship between increased abdominal distance and increased lumbopelvic pain in women who gave birth between the ages of 30 and 45 years. However, there was a correlation between the time that had elapsed since the last delivery and low back pain. Conclusions: there was a correlation between the time that had elapsed since the last delivery and low back pain. Further studies analysing factors that may perpetuate the chronicity of symptoms, such as lifestyle and intrinsic factors, are needed.

Unique Case of Rare Non-Neural Granular Cell Tumor of the Rectus Abdominis Muscle.

Background and Objectives: Our report contributes a unique case of a non-neural GCT occurring in an unusual location, with its development during pregnancy adding to its rarity. Materials and Methods: Granular cell tumors (GCTs), also known as Abrikossoff's tumors, are rare neoplasms of Schwann cell origin with predominantly benign behavior. We present a case of a 29-year-old female with a non-neural variant of a GCT discovered incidentally during a cesarean section, situated on the posterior surface of the rectus abdominis muscle. Results: Histologically, the tumor exhibited features consistent with a benign non-neural GCT, confirmed through an immunohistochemical analysis. Despite the atypical presentation and challenging surgical removal due to prior scarring, the patient experienced no postoperative complications and showed no signs of recurrence during follow-up. Conclusions: This case highlights the importance of considering GCTs in differential diagnoses, particularly in unusual anatomical locations, and underscores the favorable prognosis associated with timely surgical intervention.

Risk factors for stoma prolapse after laparoscopic loop colostomy.

BACKGROUND: Stoma prolapse (SP) is a common stoma-related complication, particularly in loop colostomies. This study aimed to investigate potential risk factors for SP development after laparoscopic loop colostomy. METHODS: In total, data from 140 patients who underwent laparoscopic loop colostomy were analyzed between September 2016 and March 2022. Risk factors for SP were investigated retrospectively. RESULTS: The median follow-up duration after colostomy was 12.5 months, and SP occurred in 33 (23.6%) patients. Multivariate analysis showed that being overweight (body mass index ≥ 25; odds ratio [OR], 8.69; 95% confidential interval [CI], 1.61-46.72; p = 0.012) and having a thin rectus abdominis penetration of the stoma (< 8.9 mm; OR, 8.22; 95% CI, 2.50-27.05; p < 0.001) were independent risk factors for SP. Other patient characteristics and surgical factors associated with stoma construction were unrelated to SP development. CONCLUSIONS: Being overweight and the route penetrating the thinner rectus abdominis during stoma construction was associated with a significantly higher incidence of SP after laparoscopic loop colostomy. Selecting a construction site that penetrates the thicker rectus abdominis muscle may be crucial for preventing SP.

The effect of ultrasound-guided rectus sheath block on postoperative analgesia in robot assisted prostatectomy: A randomized controlled trial.

BACKGROUND: Postoperative pain continues to represent an important problem even after minimally invasive robotic-assisted laparoscopic radical prostatectomy, which results in discomfort in the postoperative period and sometimes prolongs hospital stays. Regional anesthesia and analgesia techniques are used in addition to systemic analgesics with the multimodal approach in postoperative pain management. Ultrasound-guided fascial plane blocks are becoming increasingly important, especially in minimally invasive surgeries. Another important cause of discomfort is urinary catheter pain. The present randomized controlled study investigated the effect of rectus sheath block on postoperative pain and catheter-related bladder discomfort in robotic prostatectomy operations. METHODS: This randomized controlled trial was conducted from March to August 2022. Written informed consent was obtained from all participants. Approval for the study was granted by the Clinical Research Ethics Committee. All individuals provided written informed consent, and adults with American Society of Anesthesiologists Physical Condition classification I to III planned for robotic prostatectomy operations under general anesthesia were enrolled. Following computer-assisted randomization, patients were divided into 2 groups, and general anesthesia was induced in all cases. Rectus sheath block was performed under general anesthesia and at the end of the surgery. No fascial plane block was applied to the patients in the non-rectus sheath block (RSB) group.Postoperative pain and urinary catheter pain were assessed using a numerical rating scale. Fentanyl was planned as rescue analgesia in the recovery room. In case of numerical rating scale scores of 4 or more, patients were given 50 µg fentanyl IV, repeated if necessary. The total fentanyl dose administered was recorded in the recovery room. IV morphine patient-controlled analgesia was planned for all patients. All patients' pain (postoperative pain at surgical site and urethral catheter discomfort) scores and total morphine consumption in the recovery unit and during follow-ups on the ward (3, 6, 12, and 24 hours) in the postoperative period were recorded. RESULTS: Sixty-one patients were evaluated. Total tramadol consumption during follow-up on the ward was significantly higher in the non-RSB group. Fentanyl consumption in the postanesthesia care unit was significantly higher in the non-RSB group. Total morphine consumption was significantly lower in the RSB group at 0 to 12 hours and 12 to 24 hours. Total opioid consumption was 8.81 mg in the RSB group and 19.87 mg in the non-RSB group. A statistically significant decrease in urethral catheter pain was noted in the RSB group at all time points. CONCLUSION: RSB exhibits effective analgesia by significantly reducing postoperative opioid consumption in robotic prostatectomy operations.

COMPARISON OF ABDOMINAL EXERCISES AND NEUROMUSCULAR ELECTRICAL STIMULATION ON DIASTASIS RECTI ABDOMINIS MUSCLE IN POSTNATAL FEMALES WITH CAESAREAN SECTION.

The separation of the two rectus abdominis muscles along the linea alba is termed diastasis of recti abdominis muscles (DRAM). DRAM is a common health problem in people that are both pregnant and postpartum. With a 100% frequency at gestational week 35, it is extremely frequent during pregnancy. Control and function of the trunk are greatly influenced by the musculature of the abdomen. The existence, extent, and duration of DRAM have been connected to low back and pelvic discomfort however the relationship is not conclusive. It has been proven to weaken abdominal muscles and impair their functioning in lumbo-pelvic stability. Additionally, DRAM has been linked to pelvic floor dysfunction. The mechanical control and function of the abdomen can be compromised by diastasis recti, which compromises the abdominal muscles. This study examined the impact of abdominal exercises and neuromuscular electrical stimulation on the DRAM in postnatal females who underwent Caesarean section. A total of 208 individuals, aged between 20 and 34, who had recti diastasis measuring more than 2.5 cm, underwent screening. They were split into two groups at random. Group B only received abdominal exercises, whereas Group A received NMES in addition to their activities. For a period of 12 weeks, the intervention was given to both groups three times a week. Changes have been recorded before and after the intervention. The pressure biofeedback unit, measuring tape, and vernier caliper were employed to evaluate the outcome measures of inter-recti distance, abdominal muscle strength, and waist-hip ratio, respectively. In every outcome, both groups had a highly significant (p<0.05) improvement. Furthermore, after 12 weeks, group A had improved in all measures with highly significant (p<0.05) intergroup comparisons. In comparison to MNES alone, NMES can have a more significant effect on reducing DRAM in postpartum women when paired with abdominal Exercise.

Transverse division of the rectus abdominis muscle in deep inferior epigastric perforator flap elevation: A rescue technique to include more than one perforator.

BACKGROUND: It is important to include as many perforators as possible in order to enhance the vascularity of a deep inferior epigastric perforator (DIEP) flap. However, the rectus muscle must be transected transversely, which prevents suturing and can cause a defect along the same line as the muscle-sparing procedure. When harvesting the DIEP flap, no specific method was suggested to solve these muscle defects. We found that by transecting the rectus muscle transversely, the muscle could be sutured in the tendinous area more easily while maintaining muscle function. The purpose of this study is to confirm the long-term recovery of the rectus abdominis muscle through the volume change after DIEP flap using this tendinous transection and suture method. PATIENTS AND METHODS: A retrospective review of 28 patients who underwent unilateral breast reconstruction using a DIEP flap and the tendinous transection method for multiple perforators between May 2018 and April 2020 was conducted. The preoperative and postoperative volumes of the rectus abdominis muscle were estimated both the harvest and opposite sides. RESULTS: The preoperative and postoperative muscle volumes from the harvest side were 50.08 ± 8.71 cm3 and 48.56 ± 8.61 cm3, respectively. The volume difference was 1.522 cm3 decrease, which was not statistically significant (p = .070). The preoperative and postoperative muscle volumes from the opposite side were 50.50 ± 8.15 cm3 and 50.08 ± 8.18 cm3, respectively. The volume difference was 0.434 cm3 increase and was not statistically significant (p = .064). Postoperative volume changes in the rectus muscle were not statistically significant on either side. CONCLUSION: The tendinous transection method in the DIEP flap procedure did not significantly affect postoperative rectus muscle volume. Therefore, we expect this harvest method to allow DIEP flap reconstruction that includes multiple perforators and complete donor muscle recovery.

Preoperative versus postoperative ultrasound-guided rectus sheath block for acute postoperative pain relief after laparoscopy: A retrospective cohort study.

Although rectus sheath block (RSB) is routinely used in laparoscopic surgeries to reduce mid-abdominal pain, whether RSB should be performed before or after surgery remains unclear. Herein, the optimal timing for RSB in patients undergoing laparoscopic surgery was investigated. This retrospective cohort study analyzed the data of patients who underwent RSB during laparoscopic procedures at our hospital between January 2013 and December 2018. The primary outcome was the time to rescue analgesia within 24 hours postanesthesia. The patients were divided into preoperative (pre-) and postoperative (post-) RSB groups. A multivariable Cox proportional hazards regression model was used to analyze the time to rescue analgesia in the unmatched and propensity score (PS)-matched patient populations. In total, 609/14,284 patients were included (pre-RSB group, 227 patients; post-RSB group, 382 patients). After PS matching, 97 patients were assigned to both groups. Although the time from extubation to the first analgesic request was not significantly different between the 2 groups (322 vs 294 minutes, P = .57), the patients in the pre-RSB group showed a lower risk of postoperative first analgesic administration after PS matching (adjusted hazard ratio, 0.71; 95% confidence interval, 0.53-0.95; P = .023). Among patients undergoing laparoscopic surgery, those in the pre-RSB group tended to have a longer time to the first analgesic request and had a lower risk of analgesic administration within the first 24 hours than those in the post-RSB group. Thus, performing RSB preoperatively may be preferable.

Nephrotic syndrome with rectus sheath hematoma: a case report.

BACKGROUND: Rectus sheath hematoma is a rare presentation often associated with abdominal trauma and anticoagulant therapy. Here, we present a patient with severe rectus sheath hematoma accompanied by nephrotic syndrome who achieved significant clinical improvement without the need for invasive treatment. CASE PRESENTATION: A 72-year-old Japanese woman was referred to our hospital for the treatment of nephrotic syndrome. She was receiving steroid and anticoagulant therapy. Then she had abdominal pain and she was diagnosed with spontaneous rectus sheath hematoma by abdominal computed tomography. She received transfusion and was managed conservatively with bed rest, which led to improvement in abdominal pain. CONCLUSION: Despite the absence of trauma history, rectus sheath hematoma should be considered in patients at risk of vascular failure, including those receiving anticoagulant or steroid therapy, those who are elderly, and those with nephrotic syndrome.

Pregnant women may exercise both abdominal and pelvic floor muscles during pregnancy without increasing the diastasis recti abdominis: a randomised trial.

QUESTION: What is the effect of a 12-week abdominal and pelvic floor muscle exercise program during pregnancy on the inter-recti distance (IRD) in women with diastasis recti abdominis immediately after the 12-week intervention period and at follow-up 6 weeks postpartum? DESIGN: An exploratory, parallel-group, randomised controlled trial with concealed allocation, assessor blinding and intention-to-treat analysis. PARTICIPANTS: Ninety-six pregnant women aged ≥ 18 years, either primigravida or multigravida, in gestation week 24 with an IRD of ≥ 28 mm measured at rest and/or a protrusion on initial assessment. INTERVENTION: The experimental group participated in a 12-week abdominal and pelvic floor muscle exercise program during pregnancy. The control group received no intervention. OUTCOME MEASURES: Change (mm) in IRD 2 cm above and below the umbilicus at rest from pre-intervention to immediately post-intervention and to 6 weeks follow-up measured with ultrasonography. RESULTS: The IRD increased for both groups from baseline to immediately after the intervention and decreased from after the intervention to the follow-up at 6 weeks postpartum. The IRD was smallest for both groups at the follow-up. At 2 cm above the umbilicus, the intervention effect was 2 mm (95% CI -2 to 7) immediately after the intervention and -1 mm (95% CI -4 to 3) at follow-up. At 2 cm below the umbilicus, the intervention effect was -5 mm (95% CI -10 to 0) immediately after the intervention and 0 mm (95% CI -4 to 4) at follow-up. CONCLUSION: Abdominal and pelvic floor muscle training during pregnancy have a negligible effect on the IRD immediately after 12 weeks of intervention and at 6 weeks post-partum. REGISTRATION: NCT04960800.

Soft-tissue reconstruction with pedicled vertical rectus abdominis myocutaneous flap after total or high sacrectomy for giant sacral tumor.

BACKGROUND: The large soft-tissue defect after total or high sacrectomy for giant sacral tumor induces high incidence of wound complications. It remains a huge challenge to reconstruct the soft-tissue defect and achieve the preferred clinical outcome. METHODS: A total of 27 patients undergoing one-stage total or high sacrectomy for giant sacral tumors between 2016 and 2021 in a tertiary university hospital were retrospectively reviewed. Participants were divided into two groups. Thirteen patients underwent a pedicled vertical rectus abdominis myocutaneous (VRAM) flap reconstruction, whereas 14 patients underwent a conventional wound closure. Patient's clinical characteristics, surgical duration, postoperative complications, and outcomes were compared between the two groups. RESULTS: Patients in VRAM and non-VRAM groups were similar in baseline characteristics. The mean tumor size was 12.85 cm (range: 10-17 cm) in VRAM group and 11.79 cm (range: 10-14.5 cm) in non-VRAM group (P = 0.139). The most common giant sacral tumor is chordoma. Patients in VRAM group had a shorter length of drainage (9.85 vs 17.14 days), postoperative time in bed (5.54 vs 17.14 days), and total length of stay (19.46 vs 33.36 days) compared with patients in non-VRAM group. Patients in the VRAM group had less wound infection and debridement than patients in non-VRAM group (15.4% vs 57.1%, P < 0.001). CONCLUSIONS: This study demonstrates the advantages of pedicled VRAM flap reconstruction of large soft-tissue defects after high or total sacrectomy using the anterior-posterior approach. This choice of reconstruction is better than direct wound closure in terms of wound infection, length of drainage, and total length of stay.
