Abdominal compartment syndrome and intra-abdominal hypertension in critically ill patients: diagnostic value of computed tomography.

AIMS: The aims of the present work were to reevaluate, prospectively, the diagnostic value of already-described computed tomography (CT) landmarks of intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) and to study the diagnostic value of some undescribed CT signs for the diagnosis of IAH and ACS. MATERIALS AND METHODS: Consecutive patients admitted to the intensive care unit (ICU) in shock for whom an abdominal CT was clinically indicated were included. CT examinations were reviewed and scored by two reviewers for the 12 proposed CT features of IAH and ACS. Intravesical pressure (IVP) was measured for each patient. Imaging features and clinical data of patients with IAH (IVP ≥ 12 mmHg) were compared to those of patients with normal intra-abdominal pressure (IVP < 12 mmHg). RESULTS: Forty-one patients were included. Twenty-one patients (51%) presented IAH with an IVP value ≥ 12 mmHg. Four patients (10%) were considered to have ACS (10%). Only an increased peritoneal-to-abdominal height ratio (PAR) was associated with the presence of IAH (PAR = 0.45 [0.40-0.49] in patients with IVP < 12 mmHg and PAR = 0.52 [0.48-0.53] in patients with IVP ≥ 12 mmHg; p < 0.001). Increased PAR ≥ 0.52 had a specificity of 85% for IAH diagnosis. CONCLUSION: The present study suggests that a PAR ≥ 0.52 could help radiologists to identify IAH on abdominal CT scan and could lead to adequate identification and/or treatment, even at early stages of IAH. KEY POINTS: • CT is an efficient first-intention procedure to evaluate and follow up underlying conditions in critically ill patients at risk of IAH and ACS overcome. • Raising the possibility of an IAH on a CT examination is relevant information for the clinician. • The only factors associated with intra-abdominal hypertension were the peritoneal-to-abdominal height ratio (PAR) and the ratio of maximal anteroposterior to transverse abdominal diameter (which define the round belly sign when > 0.8).

Acute colitis: differential diagnosis using multidetector CT.

AIM: To investigate the utility of multidetector CT (MDCT) in helping to establish the underlying cause of acute colitis. METHODS AND MATERIALS: All patients who had acute colitis with a well-identified cause and underwent abdomen 64-MDCT were included in the study. MDCT images were retrospectively analysed in a blinded fashion and the CT findings were correlated with the eventual aetiological diagnosis. RESULTS: The study population included 105 patients. Acute colitis was related to inflammatory bowel disease in 43 cases. MDCT was used to identify six relevant signs of inflammatory colitis: the "comb" sign (p < 0.001), enlarged lymph nodes (p < 0.001), abscess (p = 0.026), fibro-fatty infiltration (p = 0.007), small bowel involvement (p < 0.001), and the absence of an "empty colon" sign (p = 0.045). Multivariate logistic regression analysis identified three independent signs of inflammatory colitis: the "comb" sign, small bowel involvement, and enlarged lymph nodes. Acute colitis was related to bacterial infection in 35 cases. Five signs were significantly associated with infectious colitis: continuous distribution (p = 0.020), an "empty colon" sign (p = 0.002), absence of fat stranding (p = 0.013), and absence of a "comb" sign (p = 0.010) and absence of enlarged lymph nodes (p = 0.035). Multivariate analysis identified three independent signs: the "empty colon" sign and absence of fat stranding and of a "comb" sign. The remaining causes were ischaemic colitis (n = 21) and drug-related colitis (n = 6). MDCT examination provided five relevant signs of ischaemic colitis: fat stranding (p = 0.002), discontinuous distribution (p < 0.001), and absence of enlarged lymph node (p < 0.001), a "comb" sign (p = 0.006) and small bowel involvement (p = 0.037). CONCLUSIONS: MDCT provides certain suggestive signs that may be helpful in distinguishing the underlying aetiological cause of acute colitis.

Inflammatory appendix mass in patients with acute appendicitis: CT diagnosis and clinical relevance.

The purpose of our study was to analyze the clinical relevance of computerized tomography (CT) in providing the diagnosis of inflammatory appendix mass (IAM) in patients with acute appendicitis. The CT images of 134 patients were reviewed. Two groups of patients were made according to the presence (group 1; n = 21) or the absence (group 2; n = 113) of IAM. Clinical signs of patients, CT features, complications at surgery, and histological examinations were noted. Inter-observer agreement was assessed by using kappa statistics. Twenty-one patients presenting with CT features of IAM were diagnosed. An excellent inter-observer agreement (κ = 0.94) was assessed for the diagnosis of IAM. No significant statistical difference in the age distribution was observed between patients with IAM (mean age 55) and patients without (mean age 45) (p = 0.2232). No clinical sign showed a statistically significant association with the presence of IAM (p = 0.707) or with complication encountered at surgery (p = 0.180). Delay to CT examination was 5.4 days in patients presenting with CT features of IAM and of 1.7 days for patients presenting without (p = 0.0001). Conversely to acute appendicitis complicated by simple perforation (p = 0.153) or peri-appendicular abscess (p = 0.501), acute appendicitis presenting with IAM showed a statistically significant association with complications encountered at surgery (p = 0.0003) and the need for conversion to open surgery (p = 0.001). Performing CT in complicated acute appendicitis provides the diagnosis of IAM. Distinction of IAM appeared to be of clinical relevance, since immediate surgery in IAM was statistically associated with surgical complications and conversion to open surgery in our study.

DCF (docetaxel, cisplatin and 5-fluorouracil) chemotherapy is a promising treatment for recurrent advanced squamous cell anal carcinoma.

BACKGROUND: Squamous cell carcinoma of the anal canal (SCCA) is a rare disease, mostly diagnosed at early stage. After concurrent chemoradiation (CRT) with mitomycin C and 5-fluorouracil (5FU), local or metastatic recurrences occur in >20% of the patients. After treatment failure, cisplatin (CDDP)-based chemotherapy is the standard option, but complete response (CR) is a rare event and the prognosis remains poor. PATIENTS AND METHODS: Eight consecutive patients with advanced recurrent SCCA after CRT were treated with DCF regimen (docetaxel 75 mg/m(2) day 1, CDDP 75 mg/m(2) day 1 and 5FU at 750 mg/m(2)/day for 5 days every 3 weeks). Tumour samples were analysed for human papillomavirus (HPV) genotyping, as well as p16 and p53 expression. RESULTS: After a median follow-up of 41 months, the overall survival rate at 12 months was 62.5% (95% CI 22.9-86.1 months). Four patients achieved a complete remission and remain relapse-free at the time of analysis with a progression-free survival of 19, 33, 43 and 88 months. Three of these patients underwent surgery for all involved metastatic sites. For all of them, pathological CR was confirmed. DCF regimen appeared feasible in these patients previously exposed to pelvic CRT, and no grade IV toxicity occurred. All patients in complete remission had HPV-16-positive SCCA, while HPV could only be detected among 50% of the non-responding patients. Of interest, immunohistochemical study revealed a p16(+)/p53(-) phenotype in these patients, while none of non-responders expressed p16. CONCLUSION: The high level of complete and long-lasting remission among SCCA patients treated with DCF regimen supports the assessment of this strategy in prospective cohorts.

Non-invasive diagnosis of severe alcoholic hepatitis: Usefulness of cross-sectional imaging.

PURPOSE: To describe the computed tomography (CT) and magnetic resonance imaging (MRI) features of severe acute alcoholic hepatitis (SAAH) and estimate the capabilities of CT and MRI in differentiating SAAH from alcoholic cirrhosis and non-alcoholic steato-hepatitis (NASH) cirrhosis. MATERIALS AND METHODS: Fifty patients with pathologically proven SAAH (SAAH group) who underwent CT or MRI examinations up to 30 days before or 15 days after liver biopsy between January 2008 and June 2018 were retrospectively included. There were 31 men and 29 women with a mean age of 52±9 (SD) years (range: 33-67 years). Imaging features of the SAAH group were compared to those obtained in two control groups including 62 patients with alcoholic cirrhosis without acute alcoholic hepatitis (control group 1) and 19 patients with NASH cirrhosis (control group 2) by two independent radiologists blinded to the final diagnosis. Univariate analyses were performed to compare imaging characteristics between the three groups, followed by diagnostic performance analysis for the diagnosis of SAAH of the main CT features. RESULTS: Heterogeneous steatosis was significantly more frequent in SAAH group than in the control groups (41/50; 82% vs. 7/62; 10% and 1/19; 5% in control groups 1 and 2, respectively for reader 1 and 34/50; 68% vs. 8/62; 13% and 1/19; 5% in control groups 1 and 2, respectively for reader 2; both P=0.01). Transient perfusion disorders were more frequent in SAAH group than in the control groups (35/50; 70% vs. 12/62; 21% and 5/19; 26% in control groups 1 and 2, respectively for reader 1 and 39/50; 78% vs. 14/62; 23% and 13/19; 6% in control groups 1 and 2, respectively for reader 2; both P=0.01). The combination of these two findings yielded 100% specificity (45/45; 95% CI: 92-100) for readers 1 and 2 for the diagnosis of SAAH vs. alcoholic cirrhosis and NASH cirrhosis. CONCLUSION: The imaging features of SAAH are specific and mainly associate transient heterogeneous steatosis and liver perfusion disorders. CT/MRI may be useful to differentiate SAAH from alcoholic cirrhosis and NASH cirrhosis.

CT in predicting abdominal cocoon in patients on peritoneal dialysis.

AIM: To evaluate the computed tomography (CT) signs of encapsulating peritoneal sclerosis (EPS) in patients on peritoneal dialysis (PD) as predictive factors for the evolution to abdominal cocoon (AC). MATERIALS AND METHODS: Clinical features and CT signs of 90 patients on PD were retrospectively reviewed. According to the clinical features, they were divided into three groups (asymptomatic, moderate, or severe). Clinical results were correlated with previously reported CT signs of EPS, i.e., peritoneal thickening, peritoneal calcifications, loculated fluids, small bowel faeces sign, small bowel obstruction, clustered bowel loops, pseudo sac, signs of bowel ischaemia or necrosis. AC was defined at CT by the association of clustered bowel loops and a pseudo sac. Statistical analysis was performed using the Fisher's exact test and the t-test. RESULTS: Although demonstrated in symptomatic patients (p=0.041), the occurrence of AC was not correlated with the severity of the symptoms (p=0.16). Among the CT signs, the presence of loculated fluids (p=0.011), a small bowel faeces sign (p=0.002); and small bowel obstruction (p=0.0001) were found to be statistically correlated with the appearance of an AC. Moreover, the association of loculated fluids, small bowel faeces sign, small bowel obstruction was extremely sensitive and specific in the development of AC (sensitivity=67%, specifity=100%, positive predictive value=100%, negative predictive value=96%). CONCLUSION: CT should be carried out in every symptomatic patient on PD. Indeed, the association of loculated fluid, small bowel faeces sign, and small bowel obstruction enables the prediction of the development of AC, which is likely to curtail PD and require surgery.

[Value of multidetector-row CT in the management of sigmoid volvulus]. / Apport du scanner multi-détecteurs dans la prise en charge des volvulus du sigmoïde.

PURPOSE: To determine the value of multidetector-row CT (MDCT) in the management of sigmoid volvulus. MATERIALS AND METHODS: Twenty-three MDCT examinations showing sigmoid volvulus were retrospectively evaluated and analyzed based on the type of volvulus (mesentericoaxial versus organoaxial), degree of rotation (180 degrees or 360 degrees ), maximum diameter of the volvulized sigmoid loop and presence or absence of the northern exposure sign, signs of bowel wall ischemia, and ascitis. A statistical analysis was performed to determine the correlation between patients characteristics, CT findings, type of management, and histological findings when available. RESULTS: In our study, organoaxial volvulus occurred in older patients (p=0.047), had a higher risk of recurrence (p=0.015) and more frequently required urgent surgical management than mesentericoaxial volvulus. A higher degree of rotation was associated with a more distended volvulized sigmoid colon (p=0.033) and more frequently required surgery. CONCLUSION: In addition to detection of volvulus and signs of bowel wall ischemic, MDCT can characterize the type of volvulus and degree of rotation, findings that may assist in determining the severity of the process and direct towards optimal management, endoscopic or surgical.

[CT guided dual site infiltration in pudendal neuralgia]. / Infiltration scano-guidée en deux sites dans la névralgie pudendale.

PURPOSE: To assess the value of CT guided dual site infiltration in patients with pudendal neuralgia and determine prognostic factors of efficacy. Materials and methods. Retrospective review of 49 patients with suspected pudendal neuralgia who underwent one or multiple injections of local anesthetics and steroids. Patients were classified based on clinical and electrophysiological findings. RESULTS: 70% of patients with typical symptoms of pudendal neuralgia responded favorably to the infiltrations compared to 27% of patients with atypical symptoms (p<0.05). The mean number of infiltrations was 2.2. 84% of responding patients experienced symptomatic relief after the first infiltration. The mean duration of symptomatic relief was 3 months. CONCLUSION: Infiltration is an effective treatment for patients with typical pudendal neuralgia, and should be included in the management of these patients.

Can three-dimensional pelvimetry using low-dose stereoradiography replace low-dose CT pelvimetry?

PURPOSE: To evaluate the reliability of pelvimetric measurements performed using stereoradiographic imaging (SRI), and to assess maternal and fetal radiation doses compared to low-dose computer tomography (CT) pelvimetry. MATERIALS AND METHODS: Thirty-five pregnant women (mean age, 29.6±5.5 [SD] years; range: 20-41 years) were prospectively included. All women underwent simultaneous frontal and lateral low-dose SRI and low-dose CT examination of the pelvis. Pelvimetry measurements were obtained from both examinations and radiation doses obtained with the two techniques were compared. RESULTS: SRI-CT correlation (Pearson coefficient correlation [r]; mean bias [mb]) was strong for transverse inlet diameter (r=0.92; mb=-0.09cm), anteroposterior diameter of the pelvic inlet (r=0.92; mb = 0.47cm), maximal transverse diameter (r=0.9; mb=0.21cm), sacrum length (r=0.9; mb=0.09cm). Correlation was good. Correlation was good for the sacrum depth (r=0.75; mb=0.06cm) and Magnin's index (r=0.7; mb=0.5cm). Correlation was moderate for anteroposterior diameter of pelvic outlet (r=0.6; mb=0.52cm). The fetal dose was 13.1 times lower using SRI (87±26µGy) than CT (1140±220µGy, P<0.0001). The effective maternal dose was 3.1 times lower using SRI (97±21µSv) than CT (310±60µSv; P<0.0001). CONCLUSION: Pelvic inlet measurements using SRI are reliable. Compared to CT pelvimetry, SRI leads to a significant decrease in fetal and maternal radiation doses. These findings should prompt physicians to use SRI as the first-line approach for pelvimetry.

Acute appendicitis: Factors associated with inconclusive ultrasound study and the need for additional computed tomography.

PURPOSE: To identify variables associated with inconclusive ultrasound examination and the need for further abdominopelvic computed tomography (CT) examination for the diagnosis of acute appendicitis. MATERIALS AND METHODS: A total of 105 adult patients with acute appendicitis were included. There were 55 patients (38 men, 17 women; mean age, 23±9 [SD] years; range: 15-58 years) with a diagnosis of acute appendicitis using ultrasound alone and 50 patients (30 men, 20 women; mean age, 31±14 [SD] years; range: 16-83 years) who required further CT. Demographic, clinical, and biological criteria and appendix location were compared between the two groups to search for variables associated with the need of further CT. RESULTS: Patients who required further CT were older (31.1±14 [SD] years) and had a greater body mass index (BMI) (26.7±4.3 [SD]kg/m2) than those who did not require CT (23±9 [SD] years and 22.9±3.4 [SD]kg/m2), respectively (P<0.01). A greater proportion of patients with complicated acute appendicitis was observed in patients who required further CT (9/50; 18%) than in those who had only ultrasound (1/55; 2%) (P=0.012). Atypical appendix location was more frequent in patients who required CT (19/50; 36%) than in those who had only ultrasound (6/55; 11%) (P<0.001). There were no significant differences regarding gender, inflammatory syndrome and hours of imaging (on call vs. working hours) between the two groups. CONCLUSION: Advanced age, high BMI, atypical appendix location, and complicated appendicitis are associated with inconclusive ultrasound and the need for further CT to diagnose acute appendicitis.

In situ delivery of allogeneic natural killer cell (NK) combined with Cetuximab in liver metastases of gastrointestinal carcinoma: A phase I clinical trial.

Despite successful introduction of NK-based cellular therapy in the treatment of myeloid leukemia, the potential use of NK alloreactivity in solid malignancies is still elusive. We performed a phase I clinical trial to assess the safety and efficacy of in situ delivery of allogeneic NK cells combined with cetuximab in liver metastasis of gastrointestinal origin. The conditioning chemotherapy was administrated before the allogeneic NK cells injection via hepatic artery. Three escalating doses were tested (3.106, 8.106 and 12.106 NK cells/kg) following by a high-dose interleukin-2 (IL-2). Cetuximab was administered intravenously every week for 7 weeks. Nine patients with liver metastases of colorectal or pancreatic cancers were included, three per dose level. Hepatic artery injection was successfully performed in all patients with no report of dose-limiting toxicity. Two patients had febrile aplasia requiring a short-term antibiotherapy. Grade 3/4 anemia and thrombopenia were also observed related to the chemotherapy. Objective clinical responses were documented in 3 patients and among them 2 occurred in patients injected with cell products harboring two KIR ligand mismatches and one in a patient with one KIR ligand mismatch. Immune monitoring revealed that most patients presented an increase but transient of IL-15 and IL-7 cytokines levels one week after chemotherapy. Furthermore, a high expansion of FoxP3+regulatory T cells and PD-1+ T cells was observed in all patients, related to IL-2 administration. Our results demonstrated that combining allogeneic NK cells transfer via intra-hepatic artery, cetuximab and a high-dose IL-2 is feasible, well tolerated and may result in clinical responses.

[Ultrasound interstitial mini invasive probes for thermal ablation in liver: feasibility study in vivo]. / Sondes ultrasonores interstitielles mini-invasives pour l'ablation thermique dans le foie: étude de faisabilité in vivo.

High intensity ultrasounds are routinely used for thermal ablation of some cancers. However, for treating hepatic tumours with physical agents, RF applicators and cryoprobes are still preferred. The goal of the present study was to demonstrate the feasibility of using interstitial ultrasound probes in liver following two approaches: percutaneous and intra-tissular or endo vascular. In vivo trials on a porcine model demonstrated the minimally invasive nature of both procedures. Homogeneous and reproducible thermal lesions, up to 20 mm deep, were obtained. The work on these two original approaches deserves to be completed with more extended prospective studies. The association with an imaging method will have to be studied before proceeding to clinical trials.

Echography for nasogastric tube placement verification.

To report the interest of abdominal ultrasonography for confirming the appropriate location of nasogastric tube (NGT) in the stomach using a new dynamic test, and to illustrate the aspect of this test at ultrasonography. Clinical observation of a patient, images of abdominal ultrasonography and video of the stomach visualized by ultrasonography. We describe the video of a critically ill patient in whom, immediately after NGT insertion, aspiration of gastric liquid and instillation within the NGT was associated with ultrasonographic evidence of turbulences in the stomach. In addition to the direct visualization of the NGT in the stomach, ultrasonographic visualization of turbulences after aspiration and instillation of gastric liquid may allow to assess the appropriate positioning of the NGT.

Comparative dose levels between CT-scanner and slot-scanning device (EOS system) in pregnant women pelvimetry.

PURPOSE: To estimate fetal absorbed doses for pregnant women pelvimetry, a comparative study between EOS imaging system and low-dose spiral CT-scanner was carried out. For this purpose three different studies were investigated: in vivo, in vitro and Monte Carlo calculations. METHODS: In vivo dosimetry was performed, using OSL NanoDot dosimeters, to determine the dose to the skin of twenty pregnant women. In vitro studies were established by using a cubic phantom of water, in order to estimate the out of field doses. In the latter study, OSLDs were placed at depths corresponding to the lowest, average and highest position of the uterus. Monte Carlo calculations of effective doses to high radio-sensitive organs were established, using PCXMC and CTExpo software suites for EOS imaging system and CT-scanner, respectively. RESULTS: The EOS imaging system reduces radiation exposure 4 to 8 times compared to the CT-scanner. The entrance skin doses were 74% (p-values <0.01) higher with the CT-scanner than with the EOS system. In the out of field region, the measured doses of the EOS system were reduced by 80% (p-values <0.02). Monte Carlo calculations confirmed that effective doses to organs are less accentuated for EOS than for CT pelvimetry. CONCLUSIONS: The EOS system is less irradiating than the CT exam. The out-of-field dose which is significant, is lower in the EOS than in the CT-scanner and could be reduced even further by optimizing the time used for image acquisition.

[Three-dimensional 3D modeling: First applications in radioanatomy and interventional radiology under CT guidance]. / Modélisation tridimensionnelle des vertèbres types: Premières applications en radioanatomie et radiologie interventionnelle sous guidage tomodensitométrique.

PURPOSE: To model vertebrae in 3D to improve radioanatomic knowledge of the spine with the vascular and nerve environment and simulate CT-guided interventions. METHOD AND MATERIALS: Vertebra acquisitions were made with multidetector CT. We developed segmentation software and specific viewer software using the Delphi programming environment. RESULTS: This segmentation software makes it possible to model 3D high-resolution segments of vertebrae and their environment from multidetector CT acquisitions. Then the specific viewer software provides multiplanar reconstructions of the CT volume and the possibility to select different 3D objects of interest. DISCUSSION: This software package improves radiologists' radioanatomic knowledge through a new 3D anatomy presentation. Furthermore, the possibility of inserting virtual 3D objects in the volume can simulate CT-guided intervention. CONCLUSION: The first volumetric radioanatomic software has been born. Furthermore, it simulates CT-guided intervention and consequently has the potential to facilitate learning interventions using CT guidance.

Multiphase whole-body CT angiography before multiorgan retrieval in clinically brain dead patients: Role and influence on clinical practice.

GOALS: To evaluate the contribution of multiphase whole-body CT angiography (CTA) for identifying the contra-indications to multiorgan retrieval (MOR) and improving the preoperative organ harvesting strategy. PATIENTS AND METHODS: One hundred and eleven consecutive patients who were clinically brain dead underwent multiphase whole-body CTA to confirm the diagnosis of brain death and for assessment of MOR. The CTA protocol included volumetric acquisitions of the brain and abdominopelvic cavity without IV administration of iodinated contrast material, then images of the thorax-abdomen-pelvis 25s after IV contrast administration, of the brain at 60s and finally an abdominopelvic CT acquisition at 90s. The diagnosis of brain death was based on well-established criteria. The assessment of thorax, abdomen and pelvis was based on a systematic checklist. Post-processing imaging techniques were used in all patients. RESULTS: No organs were retrieved from 21 patients due to patient refusal (19%). Twenty-two potential MOR were denied because of general contra-indications including 12/22 (54%) based on CTA criteria alone. Finally, 68 patients were eligible for MOR and 160 organs were harvested. The exclusion of specific organs was based on CTA alone for 2/16 livers, 4/70 kidneys and 5/55 lungs. Fifty hearts and 58 pancreases were not harvested, none based on CTA results alone. Hepatic abnormalities and vascular anatomical variants were identified in 10% of patients. At least one renal artery variant was found in 28% of patients, 13% presented with a double renal vein and 8% with a hepato-mesenteric artery. CONCLUSION: Multiphase whole-body CTA for MOR is based on the simultaneous association of cerebral CTA to determine brain death with CTA of the thorax, abdomen and pelvis. This rapid, standardized and easily accessible procedure has no harmful effects on harvested kidneys. It makes it possible to select the donors and the organs to be harvested and allows the retrieving surgeon to identify and anticipate technical difficulties.

[Value of the small bowel feces sign at CT in adhesive small bowel obstruction]. / Le feces sign: valeur d'un signe TDM dans l'occlusion du grêle sur bride ou adhérences péritonéales.

PURPOSE: The purpose of this study is to describe the CT features of the small bowel feces sign and to determine its value as a positive criteria of non-severity in adhesive small bowel obstruction. MATERIALS AND METHODS: We performed a retrospective study of adhesive small bowel obstructions diagnosed by CT from January 2001 to December 2002. All CT examinations featuring a small bowel feces sign were included. Clinical follow-up was available for all included patients. RESULTS: Twenty patients were included in this study. Twelve patients underwent successful conservative treatment with nasogastric aspiration. Urgent laparotomy performed in 6 cases and delayed surgical intervention performed in 3 did not show ischemic complication. Surgical management always consisted in lysis of adhesions without intestinal resection. CONCLUSION: Recently described in the radiological literature, the small bowel feces sign appears to be the first criteria of non-severity in adhesive small bowel obstruction.

[Large bowel obstruction secondary to lumbar hernia following latissimus dorsi flap]. / Occlusion colique sur hernie lombaire secondaire à un prélèvement de lambeau du muscle grand dorsal: à propos d'un cas.

The authors report the case of a 46-year-old woman with large bowel obstruction secondary to lumbar hernia following latissimus dorsi flap. Diagnosis was made by CT. This paper describes the CT features of this rare pathology. A brief review of the literature is also presented.
