METHODS: Between February and October of 2007, three patients with giant defects of the abdominal wall after extensive tumor resection underwent reconstruction with a combination of HADN and omentum flap. Postoperative morbidities and signs of herniation were monitored. RESULTS: The abdominal wall reconstruction was successful in these three patients, there was no severe morbidity and no signs of herniation in the follow-up period. CONCLUSION: The combination of HADM and omentum flap offers a new, safe and effective alternative to traditional forms in the repair of giant abdominal wall defects. Further analysis of the long-term outcome and more cases are needed to assess the reliability of this technique.展开更多

METHODS: From August 2007 to December 2010, a total of 11 patients with 23 abdominal wall nodules (diameter 2.59 cm ± 1.11 cm, range 1.3 cm to 5.0 cm) were treated with MW ablation. One antenna was inserted into the center of tumors less than 1.7 cm, and multiple antennae were inserted simultaneously into tumors 1.7 cm or larger. A 21 gauge thermocouple was inserted near important organs which required protection (such as bowel or gallbladder) for real-time temperature monitoring during MW ablation. Treatment outcome was observed by contrast-enhanced ultrasound and magnetic resonance imaging (MRI) [or computed tomography (CT)] during follow-up. RESULTS: MW ablation was well tolerated by all patients. Six patients with 11 nodules had 1 thermocouple inserted near important organs for real-time temperature monitoring and the maximum temperature was 56 ℃. Major complications included mild pain (54.5%), post-ablation fever (100%) and abdominal wall edema (25%). All 23 tumors (100%) in this group were completely ablated, and no residual tumor or local recurrence was observed at a median follow-up of 13 mo (range 1 to 32 mo). The ablation zone was well defined on contrast-enhanced imaging (contrast-enhanced CT, MRI and/or contrast-enhanced ultrasound) and gradually shrank with time. CONCLUSION: Ultrasound-guided MW ablation may be a feasible, safe and effective treatment for abdominal wall metastatic tumors in selected patients.展开更多

An inhomogeneous tissue is considered as a combination of a homogeneous medium and a phase aberration screen. Variations of acoustic parameters such as peak positive pressure, peak negative pressure, and acoustic intensity are discussed with respect to the phase screen statistics of human abdominal walls. Results indicate that the abdominal wall can result in energy loss of the sound in the focal plane. For a typical human abdominal wall with correlation length of 7.9 mm and variance of 0.36, the peak acoustic intensity radiated from a 1MHz transmitter with a radius of 30 mm can be reduced by about 14% at the focal plane.展开更多

This report presents a surgical case of a large lipoma in the abdominal wall of a patient with Proteus syndrome. She was diagnosed with Proteus syndrome based on certain diagnostic criteria. The neoplasm increased in size gradually, producing hemihypertrophy of her left lower extremity and trunk, and spread to her retroperitoneum and her left abdominal wall. She experienced gradually progressive constipation, nausea, vomiting, and abdominal pain. Computed tomography (CT) of the abdomen demonstrated a large mass in the subcutaneous adipose tissue of the left lower abdominal wall which measured 12 cm×8 cm×6 cm in diameter and encased the left colon. This mass in the abdominal wall was excised. The weight of the excised mass was 1550 g. The histopathological diagnosis of this mass was lipoma. After surgery, the encasement of the left colon was improved, and the patient was able to move her bowels twice per day. The excision of the large lipoma in the abdominal wall contributed to the improved bowel passage in this patient with Proteus syndrome.展开更多

This study aimed to investigate the feasibility of the AWT method for noninvasively monitoring IAP in the intensive care unit(ICU).METHODS: In this prospective study, we observed patients with detained urethral catheters in the ICU of Shanghai Tenth People's Hospital between April 2011 and March 2013. The correlation between AWT and urinary bladder pressure(UBP) was analyzed by linear regression analysis. The effects of respiratory and body position on AWT were evaluated using the paired samples t test, whereas the effects of gender and body mass index(BMI) on baseline AWT(IAP<12 mm Hg) were assessed using one-way analysis of variance.RESULTS: A total of 51 patients were studied. A significant linear correlation was observed between AWT and UBP(R=0.986, P<0.01); the regression equation was Y=–1.369+9.57X(P<0.01). There were signif icant differences among the different respiratory phases and body positions(P<0.01). However, gender and BMI had no signif icant effects on baseline AWT(P=0.457 and 0.313, respectively).CONCLUSIONS: There was a signif icant linear correlation between AWT and UBP and respiratory phase, whereas body position had signif icant effects on AWT but gender and BMI did not. Therefore, AWT could serve as a simple, rapid, accurate, and important method to monitor IAP in critically ill patients.展开更多

文摘Giant hiatal hernia(GHH) comprises 5% of hiatal hernia and is associated with significant complications.The traditional operative procedure,no matter transthoracic or transabdomen repair of giant hiatal hernia,is characteristic of more invasion and more complications.Although laparoscopic repair as a minimally invasive surgery is accepted,a part of patients can not tolerate pneumoperitoneum because of combination with cardiopulmonary diseases or severe posterior mediastinal and neck emphesema during operation.The aim of this article was to analyze our experience in gasless laparoscopic repair with abdominal wall lifting to treat the giant hiatal hernia.We performed a retrospective review of patients undergoing gasless laparoscopic repair of GHH with abdominal wall lifting from 2012 to 2015 at our institution.The GHH was defined as greater than one-third of the stomach in the chest.Gasless laparoscopic repair of GHH with abdominal wall lifting was attempted in 27 patients.Mean age was 67 years.The results showed that there were no conversions to open surgery and no intraoperative deaths.The mean duration of operation was 100 min(range:90–130 min).One-side pleura was injured in 4 cases(14.8%).The mean postoperative length of stay was 4 days(range:3–7 days).Median follow-up was 26 months(range:6–38 months).Transient dysphagia for solid food occurred in three patients(11.1%),and this symptom disappeared within three months.There was one patient with recurrent hiatal hernia who was reoperated on.Two patients still complained of heartburn three months after surgery.Neither reoperation nor endoscopic treatment due to signs of postoperative esophageal stenosis was required in any patient.Totally,satisfactory outcome was reported in 88.9% patients.It was concluded that the gasless laparoscopic approach with abdominal wall lifting to the repair of GHH is feasible,safe,and effective for the patients who cannot tolerate the pneumoperitoneum.
文摘AIM: To evaluate the feasibility, safety and efficacy of ultrasound-guided microwave (MW) ablation for abdominal wall metastatic tumors. METHODS: From August 2007 to December 2010, a total of 11 patients with 23 abdominal wall nodules (diameter 2.59 cm ± 1.11 cm, range 1.3 cm to 5.0 cm) were treated with MW ablation. One antenna was inserted into the center of tumors less than 1.7 cm, and multiple antennae were inserted simultaneously into tumors 1.7 cm or larger. A 21 gauge thermocouple was inserted near important organs which required protection (such as bowel or gallbladder) for real-time temperature monitoring during MW ablation. Treatment outcome was observed by contrast-enhanced ultrasound and magnetic resonance imaging (MRI) [or computed tomography (CT)] during follow-up. RESULTS: MW ablation was well tolerated by all patients. Six patients with 11 nodules had 1 thermocouple inserted near important organs for real-time temperature monitoring and the maximum temperature was 56 ℃. Major complications included mild pain (54.5%), post-ablation fever (100%) and abdominal wall edema (25%). All 23 tumors (100%) in this group were completely ablated, and no residual tumor or local recurrence was observed at a median follow-up of 13 mo (range 1 to 32 mo). The ablation zone was well defined on contrast-enhanced imaging (contrast-enhanced CT, MRI and/or contrast-enhanced ultrasound) and gradually shrank with time. CONCLUSION: Ultrasound-guided MW ablation may be a feasible, safe and effective treatment for abdominal wall metastatic tumors in selected patients.

文摘This article theoretically studies the influence of inhomogeneous abdominal walls on focused therapeutic ultrasound based on the phase screen model. An inhomogeneous tissue is considered as a combination of a homogeneous medium and a phase aberration screen. Variations of acoustic parameters such as peak positive pressure, peak negative pressure, and acoustic intensity are discussed with respect to the phase screen statistics of human abdominal walls. Results indicate that the abdominal wall can result in energy loss of the sound in the focal plane. For a typical human abdominal wall with correlation length of 7.9 mm and variance of 0.36, the peak acoustic intensity radiated from a 1MHz transmitter with a radius of 30 mm can be reduced by about 14% at the focal plane.
文摘BACKGROUND Reconstructive repair of huge full-thickness abdominal wall defects following debridement for abdominal electric burns remains a clinically challenging task.An ideal abdominal wall repair means a re-closure of the defected abdominal wall with pedicled neurovascular myofascial flaps,restoration of the abdominal wall integrity,and maintenance of the abdominal wall muscle tension to prevent the occurrence of abdominal wall hernia.When treating huge full-thickness defects,composite autologous tissue flaps are a good option for the repair.CASE SUMMARY This study reported the case of a 43-year-old male patient suffering from fullthickness abdominal wall defects complicated with necrosis of multiple bowel segments and duodenal leak following high-voltage burns involving the left upper limb and abdomen.After debridement for abdominal electric burns and end-to-end anastomosis for the necrotic bowels,reconstruction with acellular dermal matrix grafting and vacuum sealing drainage were performed for temporary abdominal closure.The remaining 18 cm×15 cm full-thickness abdominal wall defect was repaired using a combined anterolateral thigh and tensor fascia lata free flap.The proposed method achieved the functional reconstruction of the abdominal wall.CONCLUSION This approach restored the abdominal wall integrity,maintained certain muscle tension,avoided abdominal hernia,reached satisfactory aesthetic effect,and resulted in no complications in the grafting regions.
文摘Proteus syndrome is an extremely rare congenital disorder that produces multifocal overgrowth of tissue. This report presents a surgical case of a large lipoma in the abdominal wall of a patient with Proteus syndrome. She was diagnosed with Proteus syndrome based on certain diagnostic criteria. The neoplasm increased in size gradually, producing hemihypertrophy of her left lower extremity and trunk, and spread to her retroperitoneum and her left abdominal wall. She experienced gradually progressive constipation, nausea, vomiting, and abdominal pain. Computed tomography (CT) of the abdomen demonstrated a large mass in the subcutaneous adipose tissue of the left lower abdominal wall which measured 12 cm×8 cm×6 cm in diameter and encased the left colon. This mass in the abdominal wall was excised. The weight of the excised mass was 1550 g. The histopathological diagnosis of this mass was lipoma. After surgery, the encasement of the left colon was improved, and the patient was able to move her bowels twice per day. The excision of the large lipoma in the abdominal wall contributed to the improved bowel passage in this patient with Proteus syndrome.
文摘Sigmoid metastasis of renal cell carcinoma(RCC)is very rare.Herein we report a case of pathologically proven asynchronous abdominal wall and sigmoid metastases after a right nephrectomy.An 84-year-old man underwent right radical nephrectomy for clear cell renal cell carcinoma(ccRCC)13 years ago.Solitary contralateral abdominal wall metastasis was found for left abdominal mass 9 years after nephrectomy.The man experienced melena underwent resection of sigmoid colon tumor in February,2016.The postoperative pathological examinations revealed that the tumors were metastases of ccRCC.Recurrence more than 5 years after nephrectomy has been accepted as late recurrence by the majority of urologists now.Late recurrence is one of the specific biological behaviors of RCC.Asynchronous late recurrence of abdominal wall and sigmoid metastases in ccRCC has not been reported before.When patients have sigmoid mass after nephrectomy for RCC,doctors may consider the possibility of late recurrence.

文摘BACKGROUND: Noninvasive monitoring of intra-abdominal pressure(IAP) by measuring abdominal wall tension(AWT) was effective and feasible in previous postmortem and animal studies. This study aimed to investigate the feasibility of the AWT method for noninvasively monitoring IAP in the intensive care unit(ICU).METHODS: In this prospective study, we observed patients with detained urethral catheters in the ICU of Shanghai Tenth People's Hospital between April 2011 and March 2013. The correlation between AWT and urinary bladder pressure(UBP) was analyzed by linear regression analysis. The effects of respiratory and body position on AWT were evaluated using the paired samples t test, whereas the effects of gender and body mass index(BMI) on baseline AWT(IAP<12 mm Hg) were assessed using one-way analysis of variance.RESULTS: A total of 51 patients were studied. A significant linear correlation was observed between AWT and UBP(R=0.986, P<0.01); the regression equation was Y=–1.369+9.57X(P<0.01). There were signif icant differences among the different respiratory phases and body positions(P<0.01). However, gender and BMI had no signif icant effects on baseline AWT(P=0.457 and 0.313, respectively).CONCLUSIONS: There was a signif icant linear correlation between AWT and UBP and respiratory phase, whereas body position had signif icant effects on AWT but gender and BMI did not. Therefore, AWT could serve as a simple, rapid, accurate, and important method to monitor IAP in critically ill patients.
文摘BACKGROUND Large abdominal wall defect(LAWD)caused by shotgun wound is rarely reported.CASE SUMMARY Herein,we describe a case of LAWD caused by a gunshot wound in which the abdominal wall was reconstructed in stages,including debridement,tensionreduced closure(TRC),and reconstruction with mesh and a free musculocutaneous flap.During a 3-year follow-up,the patient recovered well without hernia or other problems.CONCLUSION TRC is a practical approach for the temporary closure of LAWD,particularly in cases when one-stage abdominal wall restoration is unfeasible due to significant comorbidities.
文摘BACKGROUND Neurofibroma can be a clinical manifestation of neurofibromatosis,which is a benign neurogenic tumor that occurs sporadically.Neurofibromas in the abdomen usually appear in the retroperitoneal space.Reports on neurofibromas in the abdominal wall are rare,and multiple recurrent neurofibromas in this area have not yet been reported.CASE SUMMARY This is a case of a 73-year-old man who suffered from multiple recurrent neurofibromas in the abdominal wall for 16 years and received 13 surgical treatments.CONCLUSION We need to pay due attention to its treatment,and primary surgery should be designed thoroughly.
文摘BACKGROUND Infectious abscesses in the abdominal wall can be secondary to retained foreign bodies(e.g.,stones,use of artificial mesh,use of silk yarn in surgical suture),inflammatory diseases(e.g.,acute appendicitis),and perforated malignancies of the digestive tract(particularly the colon).Aseptic abscesses(AAs)are relatively rare.To the best of our knowledge,this is the first report of an AA in the abdominal wall accompanied by monoclonal gammopathy of undetermined significance(MGUS)at 5 years after laparoscopic proctectomy.CASE SUMMARY A 72-year-old female patient presented with an enlarged painless mass in the lower abdomen for 1 year.She had a history of obesity,diabetes,and MGUS.Her surgical history was laparoscopic resection for rectal cancer 6 years prior,followed by chemotherapy.She was afebrile.Abdominal examination revealed a smooth abdomen with a clinically palpable solid mass under a laparotomy scar in the left lower quadrant.No obvious tenderness or skin redness was spotted.Laboratory data were not remarkable.Computed tomography scan revealed a low-density mass of 4.8 cm in diameter in the lower abdominal wall,which showed high uptake on positron emission tomography.The preoperative diagnosis was an abscess or tumor,and surgical resection was recommended.The mass was confirmed to be an AA by microbiological and pathological examinations.The patient recovered well after surgery.There was no evidence of recurrence 2 years later.CONCLUSION It is important to consider underlying conditions(diabetes,chemotherapy,MGUS)which may contribute to AA formation in the surgical wound.
文摘The evolution of multi-visceral and isolated intestinal transplant techniques over the last 3 decades has highlighted the technical challenges related to the closure of the abdomen at the end of the procedure.Two key factors that contribute to this challenge include:(1) Volume/edema of donor graft;and(2) loss of abdominal domain in the recipient.Not being able to close the abdominal wall leads to a variety of complications and morbidity that range from complex ventral hernias to bowel perforation.At the end of the 90's this challenge was overcome by graft reduction during the donor operation or bench table procedure(especially reducing liver and small intestine),as well as techniques to increase the volume of abdominal cavity by pre-operative expansion devices.Recent reports from a few groups have demonstrated the ability of transplanting a full-thickness,vascularized abdominal wall from the same donor.Thus,a spectrum of techniques have co-evolved with multivisceral and intestinal transplantation,ranging from graft reduction to enlarging the volume of the abdominal cavity.None of these techniques are free from complications,however in large-volume centers the combinations of both(graft reduction and abdominal widening,sometimes used in the same patient) could decrease the adverse events related to recipient's closure,allowing a faster recovery.The quest for a solution to this unique challenge has led to the proposal and implementation of innovative solutions to enlarge the abdominal cavity.
文摘BACKGROUND:Abdominal wall hematoma is due to trauma,coagulation disorders or anticoagulation therapy complications.METHODS:in this report we present a case of a 44-year-old female who suffered from blunt abdominal trauma and presented to the emergency department with sharp abdominal pain and ecchymosis.FAST and abdominal computerized tomography(CT) revealed an abdominal wall hematoma.Treatment with an ultrasound-guided percutaneous drainage was performed successfully.RESULTS:The patient remained under observation for six hours with serial ultrasound scans,and no signs of hematoma recurrence were present.She was discharged the same day with clinical improvement.CONCLUSION:Complete history investigation and clinical examination help to make a correct diagnosis of abdominal wall hematoma,select a prompt treatment,and reduce complications.
