Effectiveness of lobulated pedicled rectus abdominis myocutaneous flap for repairing huge chest wall defect / 中国修复重建外科杂志

OBJECTIVE@#To explore the effectiveness of lobulated pedicled rectus abdominis myocutaneous flap to repair huge chest wall defect.@*METHODS@#Between June 2021 and June 2022, 14 patients with huge chest wall defects were treated with radical resection of the lesion and lobulated pedicled rectus abdominis myocutaneous flap transplantation for reconstruction of chest wall defects. The patients included 5 males and 9 females with an average age of 44.2 years (range, 32-57 years). The size of skin and soft tissue defect ranged from 20 cm×16 cm to 22 cm×22 cm. The bilateral pedicled rectus abdominis myocutaneous flaps in size of 26 cm×8 cm to 35 cm×14 cm were prepaired and cut into two skin paddles with basically equal area according to the actual defect size of the chest wall. After the lobulated pedicled rectus abdominis myocutaneous flap was transferred to the defect, there were two reshaping methods. The first method was that the skin paddle at the lower position and opposite side was unchanged, and the skin paddle at the effected side was rotated by 90° (7 cases). The second method was that the two skin paddles were rotated 90° respectively (7 cases). The donor site was sutured directly.@*RESULTS@#All 14 flaps survived successfully and the wound healed by first intention. The incisions at donor site healed by first intention. All patients were followed up 6-12 months (mean, 8.7 months). The appearance and texture of the flaps were satisfactory. Only linear scar was left at the donor site, and the appearance and activity of the abdominal wall were not affected. No local recurrence was found in all tumor patients, and distant metastasis occurred in 2 breast cancer patients (1 liver metastasis and 1 lung metastasis).@*CONCLUSION@#The lobulated pedicled rectus abdominis myocutaneous flap in repair of huge chest wall defect can ensure the safety of blood supply of the flap to the greatest extent, ensure the effective and full use of the flap tissue, and reduce postoperative complications.

Thus, it is necessary to study their effectiveness as widely used strategies. Objective. Describe the reports in the scientific literature about the effectiveness of physical therapy in the management of diastasis recti abdominis in the postpartum period. Methods. This scoping review was carried out according to the methodology proposed by Arksey and O'Malley and PRISMA- ScR. Besides, a quest was developed in the PubMed, Lilacs, ScienceDirect, Scielo, Scopus and Scholar Google databases, including articles in English and Spanish published between 2012 and 2022, selected according to the research topic. Results. Twenty-two articles were included in the qualitative synthesis, and the chosen evidence was summarized in five dimensions: participants, evaluation, intervention, results of the effectiveness of physical therapy in reducing the inter-rectus distance, and other results. Conclusion. There is diverse scientific evidence and poor methodological quality regarding to the modality and effectiveness of physical therapy in the treatment of diastasis recti abdominis. Individualized programs are suggested, that consider new evaluation paradigms, focusing on the functionality of the abdominal wall.

Analgesic effects of ultrasound-guided rectus sheath block in open gastrectomy / 中国基层医药

Objective:To investigate the analgesic effects of ultrasound-guided rectus abdominis sheath block (RSB) in open gastrectomy.Methods:Forty-one patients with gastric cancer who underwent open gastrectomy in Binzhou Hospital of Traditional Chinese Medicine from December 2019 to December 2020 were included in this study. They were randomly assigned to undergo either RSB with 40 mL of 0.375% ropivacaine (group A, n = 21) or RSB with 40 mL of 0.9% sodium chloride injection (group B, n = 20) based on total intravenous anesthesia. After skin sutures, patient-controlled analgesia (PCA) was performed. Intraoperative dose of remifentanil and postoperative dose of PCA drug were compared between the two groups. Results:Intraoperative dose of remifentanil was significantly lower in the group A than that in the group B [(1 021.4 ± 172.0) μg vs. (1 415.0 ± 330.6) μg, t = -4.04, P = 0.001]. Postoperative doses of PCA drug used by 1 and 2 hours after surgery were (1.14 ± 0.90) mL and (0.85 ± 0.70) mL respectively in group A, which were significantly lower than (1.85 ± 0.70) mL and (1.45 ± 1.00) mL in the group B ( t = -5.96, -2.75, P < 0.001, P = 0.009). There were no significant differences in postoperative doses of PCA drug used by 3, 6, 12, 24, 48 and 72 hours after surgery between the two groups (both P > 0.05). Conclusion:RSB with 40 mL of ropivacaine applied to both sides of the incision before open gastrectomy can reduce the dose of remifentanil used during surgery and the dose of PCA drug used within 2 hours after surgery.

Optimization strategy of anesthesia for liver cancer resection: serratus anterior plane block-posterior rectus sheath block-general anesthesia / 中华麻醉学杂志

Objective:To evaluate the optimization strategy of anesthesia for liver cancer resection using serratus anterior plane block-posterior rectus sheath block-general anesthesia.Methods:One hundred patients, aged 30-64 yr, with body mass index of 18-30 kg/m 2, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, with liver function Child-Pugh grade A or B, scheduled for elective liver cancer resection under general anesthesia, were divided into serratus anterior plane block combined with posterior rectus sheath block group (group S, n=50) and thoracic paravertebral block group (group T, n=50) using a random number table method.Ultrasound-guided serratus anterior plane block (20 ml) combined with posterior rectus sheath block (10 ml) was performed using 0.375% ropivacaine in group S. Ultrasound-guided paravertebral block was performed at T 7 and T 9(15 ml for each site) with 0.375% ropivacaine in group T. Anesthesia was induced with intravenous midazolam, propofol, sufentanil and cisatracurium and maintained with intravenous infusion of propofol and remifentanil and intermittent intravenous boluses of cisatracurium.BIS value was maintained at 40-60 during operation.Patient-controlled intravenous analgesia (PCIA) was performed with sufentanil and flurbiprofen at the end of operation, and oxycodone 5 mg was intravenously injected as rescue analgesic when the VAS score>3.The onset time and operation time of nerve block were recorded.The intraoperative consumption of sufentanil and remifentanil and occurrence of cardiovascular events within 30 min after skin incision were recorded.The effective pressing times of PCA and requirement for rescue analgesia within 48 h after operation were recorded.The recovery quality was measured using the 40-item quality of recovery questionnaire at 24 h before surgery and 24 and 48 h after surgery.Peripheral venous blood samples were collected at 24 h before surgery and 24 h and 7 days after surgery to determine the concentrations of interleukin-17 and interferon-gamma in serum.The postoperative time to first flatus, first ambulation time, and length of hospital stay were recorded.The nausea and vomiting, respiratory depression, skin itching, puncture site infection, pneumothorax and other adverse reactions were recorded within 48 h after operation. Results:Compared with group T, the operation time of nerve block was significantly shortened, the incidence of intraoperative hypotension was decreased ( P<0.05), and no significant change was found in the onset time of nerve block, intraoperative consumption of sufentanil and remifentanil, postoperative requirement for rescue analgesia, effective pressing times of PCA, time to first flatus, first ambulation time, and length of hospital stay, and 40-item quality of recovery scores and serum concentrations of interleukin-17 and interferon-gamma at each time point in group S ( P>0.05). No postoperative adverse reactions were found in either group. Conclusions:Compared with thoracic paravertebral nerve block combined with general anesthesia, serratus anterior plane block-posterior rectus sheath block-general anesthesia has shorter operation time and lower incidence of intraoperative hypotension when used for liver cancer resection.

Value of abdominal ultrasound in the diagnosis of postpartum diastasis of the rectus abdominis muscle / 中国基层医药

Objective:To investigate the value of abdominal ultrasound in the diagnosis of postpartum diastasis of the rectus abdominis muscle (DRA).Methods:A total of 300 pregnant women who received prenatal examination and finally gave birth in Wenzhou Hospital of Integrated traditional Chinese and Western Medicine between October 2018 and October 2020 were included in this study. All of them underwent finger test and high-frequency ultrasound to determine the degree of DRA. The occurrence of DRA was recorded. The efficacy of abdominal high-frequency ultrasound versus finger test in the diagnosis of DRA was analyzed. The high-frequency ultrasound outcomes regarding DRA distance at different positions and at different phases were compared between women with DRA and those without DRA. Results:The overall incidence of DRA among all women included in this study was 57.67% (173/300). The incidence of DRA in multiparae was significantly higher than that in primipara [73.38% (102/139) vs. 44.10% (71/160), χ2 = 26.20, P = 0.001). The incidence of DRA in women subjected to cesarean section was significantly higher than that in women subjected to vaginal delivery [68.52% (74/108) vs. 51.56% (99/192), χ2 = 8.14, P = 0.004). The sensitivity, specificity and accuracy of abdominal ultrasound in the diagnosis of DRA were 99.42%, 98.42% and 99.00%, respectively, which were significantly higher than those of finger test [80.35%,85.04%, 82.33%, χ2 = 34.61, 15.00, 49.23, all P < 0.01]. The DRA distances at different positions measured at 36 weeks of gestation and 2 weeks postpartum were significantly shorter in women with DRA than those without DRA ( t = 5.17-7.46, P < 0.001). Conclusion:Abdominal ultrasound is of high clinical application value in the early diagnosis and rehabilitation treatment of postpartum DRA.

Objective:To evaluate the dose-effect relationship of compound lidocaine hydrochloride for transverse abdominal plane-rectus abdominis sheath block (TAP-RSB) for postoperative analgesia in elderly patients undergoing laparoscopic radical colon cancer surgery with general anesthesia.Methods:Elderly patients of either sex, aged≥65 yr, with body mass index <30 kg/m 2, of American Society Anesthesiologists physical status Ⅰ-Ⅲ, undergoing elective laparoscopic radical colon cancer surgery with general anesthesia, were selected.After induction of general anesthesia, compound lidocaine hydrochloride was given under ultrasound guidance for bilateral TAP block (20 ml on each side) and for bilateral RSB (10 ml on each side), with the initial concentration of 0.4%.Each time the concentration increased/decreased in the next patient depending on whether or not the analgesia was effective.The ratio between the two successive concentrations was 1.00∶1.15.The analgesic effects were evaluated by the Numerical Rating Scale at 1 h intervals from the time of postoperative admission to the post-anesthesia care unit until 8 h after TAP-RSB (Numerical Rating Scale ≤ 3 was considered as effective analgesia). The probit method was used to calculate the half effective concentration (EC 50) and 95% effective concentration (EC 95) and 95% confidence interval of compound lidocaine hydrochloride. Results:The EC 50 and EC 95(95% confidence interval)of compound lidocaine hydrochloride for TAP-RSB were 0.289% (0.232%-0.352%) and 0.404% (0.345%-0.970%), respectively, when used for postoperative analgesia in elderly patients undergoing laparoscopic radical colon cancer surgery with general anesthesia. Conclusions:The EC 50 and EC 95 of compound lidocaine hydrochloride for TAP-RSB are 0.289% and 0.404%, respectively, when used for postoperative analgesia in elderly patients undergoing laparoscopic radical colon cancer surgery with general anesthesia.

Anatomical study and clinical importance of the inferior epigastric artery / Estudio anatómico e importancia clínica de la arteria epigástrica inferior

SUMMARY: The inferior epigastric artery (IEA) is a major blood vessel that supplies the anterior abdominal wall. The aim of the current study was to provide clinicians, surgeons, and obstetricians with sufficient anatomical data on the inferior epigastric artery, such as its origin and branching pattern. The study included 20 embalmed cadavers, these cadavers were dissected, and the inferior epigastric artery and vena comitans/venae comitantes were identified and traced downwards to the external iliac vessels. The origins, caliber, course and pedicle length of both the artery and the vein(s) were studied. The inferior epigastric artery arose independently from the distal external iliac artery deep to the inguinal ligament in 19 (95 %) cadavers. The artery entered the rectus abdominis muscle at its middle third in 13 (65 %) cases and at its lower third in the remaining specimens. In this study, we found that the artery divided into two branches in 18 (90 %) of the cases; in the remaining two cases, it continued as one trunk. The average pedicle length was 7.2 cm. The mean caliber of the IEA was 3.7 mm. In 18 (90 %) dissections, the venous drainage consisted of a pair of venae comitantes that united to form a common vessel at their draining point on the external iliac vein. The average diameter was 3.9 mm. The current study focuses on the anatomical features of the inferior epigastric artery to increase the success rate of abdominal and pelvic operations in clinical practice.

RESUMEN: La arteria epigástrica inferior (AEI) es un vaso sanguíneo principal que irriga la pared abdominal anterior. El objetivo del presente estudio fue proporcionar a los médicos, cirujanos y obstetras suficientes datos anatómicos sobre la arteria epigástrica inferior, como su origen y patrón de ramificación. El estudio incluyó 20 cadáveres embalsamados, los que se disecaron y se identificó la arteria epigástrica inferior y la vena concomitante y se siguieron hasta los vasos ilíacos externos. Se estudiaron los orígenes, calibre, trayecto y longitud del pedículo tanto de la arteria como de la (s) vena (s). La arteria epigástrica inferior surgió independientemente de la arteria ilíaca externa profunda al ligamento inguinal en 19 (95 %) cadáveres. La arteria ingresó al músculo recto del abdomen en su tercio medio en 13 (65 %) casos y en su tercio inferior en las muestras restantes. En este estudio, encontramos que la arteria se dividió en dos ramas en 18 (90 %) de los casos; en los dos casos restantes, continuó como un tronco. La longitud media del pedículo fue de 7,2 cm. El calibre medio del AEI fue de 3,7 mm. En 18 (90 %) disecciones, el drenaje venoso consistió en un par de venas concomitantes las que formaron un vaso común en su punto de drenaje en la vena ilíaca externa. El diámetro medio fue de 3,9 mm. El estudio actual se centra en las características anatómicas de la arteria epigástrica inferior con el propósito de mejorar la tasa de éxito de las cirugías abdominales y pélvicas en la práctica clínica.

Effect of closure of anterior abdominal wall layers on early postoperative findings at cesarean section: A prospective cross-sectional study

Abstract Objective To investigate the effect of closure types of the anterior abdominal wall layers in cesarean section (CS) surgery on early postoperative findings. Methods The present study was designed as a prospective cross-sectional study and was conducted at a university hospital between October 2018 and February 2019. A total of 180 patients who underwent CS for various reasons were enrolled in the study. Each patient was randomly assigned to one of three groups: Both parietal peritoneum and rectus abdominis muscle left open (group 1), parietal peritoneum closure only (group 2), and closure of the parietal peritoneum and reapproximation of rectus muscle (group 3). All patients were compared in terms of postoperative pain scores (while lying down and duringmobilization), analgesia requirement, and return of bowel motility. Results The postoperative pain scores were similar at the 2nd, 6th, 12th, and 18th hours while lying down. During mobilization, the postoperative pain scores at 6 and 12 hours were significantly higher in group 2 than in group 3. Diclofenac use was significantly higher in patients in group 1 than in those in group 2. Meperidine requirements were similar among the groups. There was no difference between the groups' first flatus and stool passage times. Conclusion In the group with only parietal peritoneum closure, the pain scores at the 6th and 12th hours were higher. Rectus abdominismuscle reapproximations were found not to increase the pain score. The closure of the anterior abdominal wall had no effect on the return of bowel motility.

Modified pararectus abdominis approach for anterior plate fixation of sacral fracture: a clinical anatomy study / 中华创伤骨科杂志

Objective:To investigate the safety and feasibility of modified pararectus abdominis approach in the anterior plate fixation of sacral fractures.Methods:In 5 fresh adult cadavers (3 males and 2 females), gross anatomy was performed on one pelvic side using a modified pararectus abdominis approach to clarify the anatomical structures around the approach. On the other side of the pelvis, the anterior structures of the sacrum were exposed in simulated anterior plate fixation of sacral fracture via the modified pararectus abdominis approach. The exposed anatomic range of the approach, and the locations and courses of lumbosacral trunk nerve and iliac vessels were observed and recorded.Results:(1) The modified pararectus abdominis approach exposed the whole S1 vertebral body from the sacroiliac joint to the medial side, the L5 vertebral body cephalally, the S1 foramina in the true pelvis, and the same structures laterally as a traditional pararectus abdominis approach did. (2) Via the modified pararectus abdominis approach, exploration and decompression of the lumbosacral plexus (from L4 to S1) (including S1 foraminoplasty) were performed under direct vision to decompress the nerve entrapment from anterior compressed fracture fragments and hyperplastic callus. (3) There was a safe surgical area in anterior L5 and S1 where a plate could be safely fixed to the S1 vertebral body. (4) Since the maximum vertical distance from the lumbosacral trunk nerve lifted above the periost to the sacral ala was 1.4 cm (range, from 1.2 to 1.5 cm), a plate could be safely placed from the subperiosteum to the S1 vertebral body to fix the fracture.Conclusions:The modified pararectus abdominis approach is safe and feasible for exploration and decompression of lumbosacral nerves in the anterior sacral region (from L4 to S1) because it has significant advantages in vision and operation. It also broadens the range of anterior sacral plate fixation because a sacral fracture displacement can be reduced under direct vision and a plate can be fixated to the S1 vertebral body along the alae sacralis and across the sacroiliac joint to the iliac bone.

Diagnosis and treatment of abdominal rectus diastasis / 中华消化外科杂志

Abdominal rectus diastasis is common in postpartum women and obese people, with clinical manifestations of midline abdominal bulge and lower back pain. Severe cases may affect the function of abdominal wall muscle groups, which cause a series of physiological dysfunction. There are few studies on the diagnosis and optimal management of abdominal rectus diastasis, especially on its surgical indications, and no uniform conclusion is achieved. The authors comprehensively analyze the research progress at home and abroad, exploring the etiology, diagnosis, treatment options and surgical indications of abdominal rectus diastasis, in order to provide references for clinical practice.

Aim: To demonstrate the anatomy and application of the anterior rectus sheet in the repair of giant abdominal wall hernias through a classic component surgery plus a turn over flap. Materials and Method: Anatomic dissection with vascular and dynamic description of the anterior rectus sheet. Posterior application of the technique in patients with giant abdominal wall hernias. Clinical follow up of recurrence, local and systemic complications. Results: 8 patients were selected. The average age was 58.6 years old and the abdominal wall defect 19.6 cm wide. The technique could be applied in every patient without inconveniences. Only 1 patient had a complication (dehiscence and partial skin flap necrosis) that was successfully treated with resection and readvancement. No systemic complications nor mortality was described. Discussion: Giant abdominal wall hernias are a surgical challenge. Great and innovative advances have been made. New biological and synthetic materials have been developed, nevertheless they frequently involve great costs and complications related to them. Also, they do not adapt adequately to the dynamic required for the abdominal wall. Conclusion: This technical modification is useful, safe and accessible for the patients who present giant wall hernias. The complication rate is low and it's principally given from problems related to skin flap blood flow.

Perineal repair after abdominoperineal excision with rectus abdominis myocutaneous flap / Reconstrução do períneo após amputação abdominoperineal com retalho pediculado do músculo reto abdominal

ABSTRACT Background: Abdominoperineal excision of the rectum (APR) remains the only potential curative treatment for very low rectal adenocarcinoma and squamous cell carcinoma of the anus. Yet, it implies a significant perineal exenteration and has set the attention on the perineal reconstruction. Aim: To present technique used in one case of APR for anal cancer, with resection of the vaginal posterior wall with large perineal defect which has called for the necessity of a flap for reconstruction Method: To cover the large perineal defect and reconstruct the posterior vaginal wall was perform a standardized and reproducible surgical technique using oblique rectus abdominis myocutaneous (ORAM) flap. The overlying skin of this flap is thick and well vascularized by both superficial branches and perforators of the superior epigastric artery and the deep inferior epigastric artery which serves as the vascular pedicle for the ORAM flap. Results: This procedure was applied in a 65-year-old woman with recurrent squamous cell carcinoma of the anus infiltrating the posterior wall of the vagina. Was performed an APR with en-bloc resection of the vaginal posterior wall in order to achieve tumor-free margins. Postoperative course was uneventful and she was discharged home at postoperative day 9. Final pathological report confirmed the oncological adequacy of the procedure (R0) and showed a rypT4N0 lesion. Conclusion: Flap reconstruction is an effective way to cover the perineal wound reducing both perineal complication rate and wound healing delay. The ORAM is particularly interesting for female whose tumors require resection and subsequent reconstruction of the posterior wall of the vagina.

RESUMO Racional: A amputação abdominoperineal do reto (APR) continua sendo o único tratamento curativo nos casos de adenocarcinoma retal muito baixo e carcinoma espinocelular do ânus. No entanto, implica em exenteração perineal significativa e exige atenção na reconstrução perineal. Objetivo: Propor, ilustrando com um caso clinico, proposta de APR para câncer anal com ressecção da parede posterior da vagina com cobertura do grande defeito perineal através de reconstrução com retalho miocutâneo oblíquo do reto abdominal (ORAM). Método: Para cobrir o defeito e reconstruir a parede vaginal posterior, realizou-se técnica de retalho miocutâneo oblíquo do reto abdominal (ORAM). A pele subjacente desse retalho por ser espessa e bem vascularizada por ramos perforantes superficiais da artéria epigástrica superior e pela artéria epigástrica inferior profunda serviu como pedículo vascular. Resultado: Este procedimento foi aplicado em uma mulher de 65 anos com recidiva de carcinoma espinocelular do ânus infiltrado na parede posterior da vagina. Foi realizada APR com ressecção em bloco da parede posterior vaginal com o objetivo de obter margens livres de tumor. O pós-operatório transcorreu sem intercorrências e a paciente recebeu alta hospitalar no 9° dia pós-operatório. O relatório patológico final confirmou a adequação oncológica do procedimento (R0) e mostrou uma lesão rypT4N0 de 6,5 cm. Conclusão: A reconstrução perineal com utilização de retalho é maneira eficaz de fechar a ferida operatória, reduzindo a taxa de complicações perineais e o atraso na cicatrização. O retalho de tipo ORAM é particularmente interessante para mulheres cujos tumores requerem ressecção e subsequente reconstrução da parede posterior da vagina.

Standardization and ten essential steps in the lateral robotic extended totally extraperitoneal (eTEP) repair of ventral hernias / Hérnias ventrais por acesso lateral totalmente extraperitoneal robótico (eTEP): dez etapas essenciais na padronização técnica

ABSTRACT Objectives: described by Dr. Jorge Daes, principles of the enhanced view totally extraperitoneal (eTEP) has been widely used in the armamentarium of ventral hernia repair recently. Robotic assisted eTEP technique feasibility has been proved, however, a complete understanding of retromuscular abdominal wall planes and its landmarks still uncertain in a majority of general surgeons. The aim of this report is to propose a technical standardization and its anatomic concepts in the robotic-assisted eTEP ventral hernia repair. Methods: our group describes 10 key steps in a structured step-by-step approach for a safe and reproducible repair based on well defined anatomic landmarks, identification of zones of dissection and correct restoration of the linea alba. Results: the standardization has been developed 2 years ago and applied to all patients. A robotic-assisted surgery with 3 robotic arms is performed in a lateral docking setup. Feasibility is established and reproducibility is high among general surgeons. Conclusion: we present a standardized side docking robotic assisted eTEP approach for ventral hernia repairs with 10 key steps. We believe understanding the landmarks and a step-by-step guidance based on the concepts of retromuscular abdominal wall anatomy foment a safe learning of minimally invasive restoration of the abdominal wall integrity regarding non-expert surgeons.

Ultrasond examination in evaluation of structure and function of rectus abdominis and pelvic floor in early postpartum women / 中国介入影像与治疗学

Objective: To investigate the value of ultrasound examinations in evaluation on structure and function of rectus abdominis and pelvic floor in early postpartum period. Methods: Transperineal pelvic ultrasound and abdominal ultrasound were performed on 102 primiparas 6-8 weeks postpartum. The levator hiatal area was measured under the maximum Valsalva maneuver, and the inter-rectus diatance (IRD) of the level of umbilicus, 3 cm above and 3 cm below the umbilicus were tested. Spearman correlation analysis was used to observe the correlation between the levator hiatal area under the maximum Valsalva maneuver and IRD of the umbilicus. Results: Transperineal pelvic floor ultrasound showed PFD in 55 women (PFD group), while no PFD was detected in 47 women (non-PFD group). The maximum levator hiatal area in non-PFD group ([14.52±2.72]cm2) was less than that in PFD group ([22.78±5.51]cm2, t=9.81, P0.05). There was positive correlation between the levator hiatal area under the maximum Valsava maneuver and IRD of umbilicus (rs=0.42,P<0.01). Conclusion: Ultrasound is of great significance in evaluating postpartum inter-rectus abdominis and pelvic floor structure, indicating that the increase in IRD during early postpartum period can adversely affect the structure and function of pelvic floor.

Diseases and Findings of the Shigyakusan Effective Cases in Our Institution / 日本東洋医学雑誌

We retrospectively surveyed and analyzed medical records of 41 effective cases with shigyakusan including shigyakusan decoction and shigyakusan extract. In classics, fullness in chest and hypochondrium and rectus abdominis muscle stiffness along with coldness of the extremities is regarded as important clinical indication of shigyakusan. In this analysis, patients who present fullness in chest and hypochondrium are more than 90%, and patients presenting rectus abdominis muscle stiffness are more than 60%, confirming that these findings are important. On the other hand, although more than half of the patients feel excessive sensitivity to cold, only about 20% of the patients had coldness of the extremities as objective Kampo findings in their medical records. Until now, coldness of the extremities has been considered to be important because shigyaku means Japanese expression of it. But our obtained results show that shigyakusan is used for the patients who do not have cold extremities.

Is rectus abdominis thickness associated with survival among patients with liver cirrhosis? A prospective cohort study

ABSTRACT BACKGROUND: Sarcopenia may affect patients with liver cirrhosis and worsen disease outcomes. OBJECTIVES: To evaluate ultrasound-measured psoas major (PM) and rectus abdominis (RA) thickness for predicting survival among patients with liver cirrhosis. DESIGN AND SETTING: Prospective cohort study in a tertiary-level hospital. METHODS: 61 patients with liver cirrhosis were prospectively included during a 15-month period and followed up for at least six months. Cirrhosis was classified using the Child-Pugh score. Sarcopenia was assessed using surrogate parameters: handgrip strength (HGS), mid-arm muscle circumference (MAMC) and SGA (subjective global assessment). We used ultrasound to measure RA and PM thickness at admission. RESULTS: There were 41 men. The patients' mean age was 58.03 ± 10.8 years. 26.22% of them were Child-Pugh A, 45.9% B and 27.86% C. The patients were followed up for 11.9 ± 5.63 months. RA thickness correlated moderately with MAMC (r = 0. 596; P < 0.0001) and HGS (r = 0.515; P < 0.0001) and decreased with increasing SGA class (A, 10.6 ± 2.8 mm; B, 8.3 ± 1.9 mm; C, 6.5 ± 1.9 mm; P < 0.0001). Survival at six months was independently predicted by using the model for end-stage liver disease-serum sodium score (odds ratio, OR 1.305; 95% OR confidence interval 1.083-1.572; P = 0.005). Survival during follow-up was independently predicted by RA thickness (hazard ratio, HR 0.701; 95% HR confidence interval 0.533-0.922; P = 0.011) and ascites (HR 1.876; 95% HR confidence interval 1.078-3.267; P = 0.026). PM thickness did not have any predictive value. CONCLUSIONS: As a surrogate marker of sarcopenia, RA thickness may predict survival among patients with liver cirrhosis.

Redefinição natural do abdome em abdominoplastia com uso de lipoaspiração convencional: estudo prospectivo / Redefining natural abdominal anatomy in abdominoplasty using conventional liposuction: a prospective study

Introdução: A evolução da abdominoplastia se mantém constante desde 1899. Atualmente, com o avanço das técnicas de lipoaspiração, o conceito de lipoaspiração de alta definição tem como objetivo de corrigir estigmas causados pelo procedimento, como o aspecto "tenso" e a falta de convexidades e concavidades naturais abdominais. Métodos: Apresentamos uma proposta de busca da redefinição natural do abdome, através da lipoabdominoplastia tradicional com lipoaspiração seletiva, procurando obter resultados cirúrgicos com padrão natural, reproduzível para a maioria dos pacientes. Foram realizadas 21 abdominoplastias, entre novembro de 2018 e maio de 2019, utilizando a técnica descrita. Resultados: A técnica demonstrada apresentou resultados estéticos satisfatórios em obter a aparência abdominal natural através da lipoaspiração profunda e superficial, em áreas de sombras abdominais. Conclusão: O trabalho demonstrou-se seguro sob o ponto de vista vascular, além de ser reprodutível ao passo que utiliza lipoaspiração convencional, utilizada pela ampla maioria dos cirurgiões plásticos.

Introduction: Abdominoplasty techniques have constantly evolved since 1899. With modern liposuction techniques, the concept of high-definition liposuction aims to correct stigmas secondary to the procedure, such as a "tense" appearance and lack of natural abdominal convexity and concavity. Methods: Here we propose a technique to redefine the natural abdominal anatomy using traditional lipoabdominoplasty with selective liposuction to achieve more natural-looking surgical results that are reproducible for most patients. This study included 21 abdominoplasty procedures using the described technique performed between November 2018 and May 2019. The technique showed satisfactory ability to achieve a natural abdominal appearance using deep and superficial liposuction in abdominal shadow areas. Conclusion: The study showed that the technique is safe from a vascular point of view and reproducible due to the use of conventional liposuction, which is available to the vast majority of plastic surgeons.

Rectus abdominis muscle flap for repair of the gastrojejunal leakage after distal gastrectomy with Billroth II anastomosis for gastric cancer / Colgajo del músculo recto abdominal para reparación de la dehiscencia gastroyeyunal luego de gastrectomía distal con anastomosis Billroth II por cáncer gástrico

Anastomotic leakages at the gastrojejunostomy site are difficult to repair, due to complex gastrointestinal anatomy. This is the first study reporting clinical use of rectus abdominis muscle (RAM) flap for repair of gastrojejunostomy leakage. A patient with leakage of gastrojejunostomy after distal gastrectomy with Billrroth II anastomosis for gastric cancer underwent repair using left RAM flap, based on superior epigastric artery. Rectus abdominis muscle flap, after being harvested was then anchored to the edges of the leak of gastrojejunostomy with few interrupted 2-0 vicryl sutures. Gastrojejunostomy leak sealed in the two cases. Rectus abdominis muscle flap for closure of gastrointestinal defect is a simple, technically easy and dependable procedure, which can be performed, quickly in critically ill patients. It can be used for repair of a large gastrointestinal defect with friable edges when omentum is not available or when other conventional methods are impractical.

Las dehiscencias anastomóticas en el sitio de gastroyeyunostomía son difíciles de reparar, debido a la compleja anatomía gastrointestinal. Este es el primer estudio que comunica el uso clínico del colgajo del músculo recto abdominal (MRA) para la reparación de la dehiscencia de gastroyeyunostomía. A un paciente con dehiscencia de gastroyeyunostomía, luego de una gastrectomía distal con anastomosis Billrroth II para cáncer gástrico, se le realizó una reparación utilizando colgajo izquierdo del MRA, basado en la arteria epigástrica superior. El colgajo del músculo recto abdominal, después de ser extraído, se fijó a los bordes de la dehiscencia de la gastroyeyunostomía con pocas suturas de vicryl 2-0 interrumpidas. La dehiscencia de la gastroyeyunostomía fue sellada. El colgajo del músculo reto abdominal para el cierre del defecto gastrointestinal es un procedimiento simple, técnicamente fácil y confiable, que puede realizarse rápidamente en pacientes críticamente enfermos. Se puede utilizar para la reparación de un gran defecto gastrointestinal con bordes friables cuando el omento no está disponible o cuando otros métodos convencionales no son prácticos.

Fibrohistiocitoma maligno gigante de face: tratamento reparador microcirúrgico utilizando retalho miocutâneo transverso do reto do abdome - Relato de caso / Giant malignant fibrous histiocytoma of the face: case report of microsurgical repair using a transverse rectus abdominis myocutaneous flap

Introdução: A ressecção de tumores invasivos de cabeça e pescoço pode resultar em defeitos extensos e complexos exigindo reparação imediata. Uma das opções de reparação é a transferência, utilizando técnica de microcirurgia vascular, do retalho musculocutâneo do reto abdominal pediculado nos vasos epigástricos inferiores profundos (TRAM). O presente estudo tem como objetivo registrar um procedimento utilizado no tratamento reparador microcirúrgico de fibrohistiocitoma maligno gigante de face com retalho TRAM. Relato de Caso: Paciente procurou atendimento médico devido a lesão tumoral gigante em hemiface direita. Foi realizada a tomografia computadorizada do crânio revelando volumoso processo expansivo de aspecto vegetante com limites mal definidos. Após os procedimentos básicos no pré-operatório, realizou-se a exérese do tumor que acometia músculos masseter e temporal direito, glândula parótida, assoalho orbitário à direita e osso malar. Posteriormente, retirou-se o retalho microcirúrgico do músculo reto do abdome em conjunto com a artéria epigástrica inferior profunda através de incisão cirúrgica da área hipogástrica. Em seguida, dissecção da artéria e veia facial utilizando microscópio e anastomoses venosa e arterial. Quanto à evolução retalho apresentou-se íntegro, com boa perfusão, sem sinais de infecção. Conclusões: A reconstrução facial microcirúrgica oferece liberdade ao cirurgião de cabeça e pescoço para realizar grandes ressecções tumorais.

Introduction: The resection of invasive tumors of the head and neck can result in extensive and complex defects requiring immediate repair. One repair option is the transfer of a transverse rectus abdominis myocutaneous (TRAM) flap pedicled on deep inferior epigastric vessels using vascular microsurgery. This study aimed to register a procedure used in the microsurgical treatment of giant malignant fibrous histiocytoma of the face using a TRAM flap. Case Report: A male patient sought medical care for a giant tumoral lesion in the right hemiface. Computed tomography of the skull revealed a voluminous expansive process of vegetating aspect with poorly defined borders. The excision of the tumor affected the right masseter and temporalis muscles, parotid gland, and right orbital and malar bones. Subsequently, microsurgical withdrawal of the TRAM flap was performed with the deep inferior epigastric artery through a surgical incision in the hypogastric area. Dissection of the facial artery and vein under microscopy and venous and arterial anastomoses followed. The flap was intact with good perfusion and no signs of infection. Conclusions: Microsurgical facial reconstruction allows head and neck surgeons to resect large tumors.
