Associating portal embolization and artery ligation to induce rapid liver regeneration in staged hepatectomy.

BACKGROUND: Insufficient volume of the future liver remnant (FLR) is a major cause of unresectability in patients with bilobar colorectal liver metastases (CLM). The objective of this study was to evaluate the safety and efficacy of the novel associating portal embolization and artery ligation (APEAL) technique before extended right hepatectomy during a two-stage procedure for CLM. METHODS: All patients who had undergone extended right hepatectomy during two-stage surgery for CLM between 2012 and 2014 were identified retrospectively from a prospectively maintained database. In the first stage, right portal vein embolization, partial right hepatic artery ligation and devascularization of segment IVb along the round ligament without parenchymal transection were associated with clearance of the FLR and/or primary tumour resection. Liver volumetry was performed using OsiriX software on postoperative day (POD) 7 and 30. RESULTS: Ten patients underwent the APEAL procedure. During the first stage, APEAL was combined with colorectal resection in seven patients. The median (range) interval between the two stages was 45 (31-71) days. The FLR volume increased from 327 (214-537) cm(3) before surgery to 590 (508-1072) cm(3) on POD 7 and 701 (512-1018) cm(3) on POD 30. This corresponded to a FLR regeneration rate of 104 (42-185) and 134 (53-171) per cent respectively. There were no deaths. The overall morbidity rate was 60 per cent (6 of 10) after each procedure, with severe morbidity occurring in two and three of ten patients after the first and second procedures respectively. CONCLUSION: APEAL induces fast, safe, reproducible and effective FLR growth when an extended right hepatectomy is scheduled in patients with multiple bilobar CLM.

[Use of a free antero-lateral thigh flap for two-stage reconstruction of a large thoracic defect]. / Utilisation du lambeau antéro-latéral de cuisse selon la technique du chausson aux pommes pour la couverture d'une large perte de substance thoracique.

In case of extremely large thoracic full-thickness defects where no pedicled flap is available, very large free flaps are sometimes the only options. Dealing with such full-thickness defects where failure of the flap could be lethal, Servant and al described the concept of "two stage free flap" using Latissimus Dorsi muscular or myocutaneous flap. We present a reconstruction of a wide right posterior trunk radionecrosis with exposure of an underlying infected prosthesis using this two-stage free flap strategy with a fasciocutaneous antero-lateral thigh flap.

[Tolerance and efficacy of lipomodelling as an element of breast symmetry in breast reconstruction]. / Tolérance et efficacité du lipomodelage comme élément de symétrisation en reconstruction mammaire: à propos de 150 patientes.

AIM OF THE STUDY: Fat transfer significantly improved results in breast reconstruction. Final breast symmetry is very important in breast reconstruction, but sometimes, the result is not perfect with usual techniques. The aim of this study is to evaluate the tolerance and efficacy of lipomodelling as a complementary technique for breast symmetrisation. MEANS AND METHODS: In this study, 150 patients had controlateral breast symmetrisation after breast reconstruction, using or completed with fat transfer. Patients were clinically evaluated one year after surgery. Age, BMI, harvested, purified and transferred fat volumes, and postoperatory complications were recorded. Morphological outcomes were evaluated by the surgeon as: very good, good, average or bad. Patients rated their degree of satisfaction as: very satisfying, satisfying, poor or bad. RESULTS: We found out that 98.6 % of morphological results were good or very good, and 86.6 % of the patients were satisfied or very satisfied with the result. Complications were rare (2 % of cytosteatonecrotic lesions). CONCLUSION: Lipomodelling in native breast symmetrisation after reconstruction is a powerful technique because it allows to increase volume of a hypoplastic controlateral breast, to ameliorate its shape, and to finally enhance mammoplasty result by correcting persisting localized volume defects. It definitively is a major therapeutic tool for enhancing breast reconstruction outcomes.

[Morbidity of neck dissection submuscular recess (sublevel IIb) in head and neck cancer]. / Morbidité des curages ganglionnaires cervicaux en cancérologie ORL (secteur IIb).

OBJECTIVES: The impact of neck dissection on quality of life has often been considered less important than the oncological control. Dissection of level IIb doesn't improve oncologic control everytime, knowing that an injury of the spinal nerve can occur. The aim of our study was to assess the impact of neck dissection including level IIb on shoulder function and quality of life in N0 patients. MATERIALS AND METHODS: Fifteen patients with squamous cell carcinoma of the upper aerodigestive tract, clinical and radiological NO, were included. They were assessed by validated scales (QLQ-C30, H&N35 and DASH) and they underwent an examination of the shoulder. RESULTS: Almost half of the patients had pain in the shoulder. The functional scale score QLQ-C30 was statistically more altered (49.7%) than that of patients with cancer in general (74.9%, p = 0.00016) and of the general population 60 to 69 years (85.4%, p = 0). CONCLUSION: The results of our study underscore the morbidity on shoulder function after neck dissection. These findings, combined with the low prevalence of occult lymph node metastases in level IIb among T1-T2 patients, must question the systematic inclusion of this level in neck dissection.

Aspergillus vertebral osteomyelitis in immunocompetent subjects: case report and review of the literature.

Aspergillus spondylodiscitis (AS) is rare in immunocompetent (IC) patients. A 65-year-old diabetic IC male subject presented with cervical AS 18 months after otomycosis. Two serological tests, mastoidectomy and biopsy of the sphenoid bone, were negative. A prevertebral biopsy identified A. flavus. The patient was successfully treated with voriconazole. Forty-three cases of AS in IC patients have been published. A predisposition was found in 84 % of cases. Fever was reported in 20 % of cases, whereas neurological defects were present in 41 %. Serology was inconsistently positive (5/7) and diagnosis was confirmed by biopsy or surgery. A. fumigatus was the most frequently isolated species (74 %). All episodes were medically treated, associated with surgery in 57 % of cases, and 73 % of patients fully recovered. AS must be discussed in IC patients presenting with risk factors, including diabetes mellitus. Biopsy is necessary to confirm diagnosis, since serology offers low sensitivity. Nevertheless, the prognosis is good.

Laryngeal paraganglioma mimicking a laryngeal haemangioma.

Paraganglioma are uncommon neuroendocrine tumours arising from extra-adrenal chromaffin cells of the autonomic nervous system. In the head and neck region, these neoplasms most commonly arise from the carotid body, the vagus nerve, and the jugulotympanic area. We present the case of a 69-year-old woman who suffered from dyspnoea and dysphonia for six months. A biopsy diagnosed a laryngeal haemangioma and a resection of the tumour was performed using supraglottic pharyngolaryngectomy. Definitive histopathological examination revealed a laryngeal paraganglioma. Laryngeal paraganglioma and haemangioma must be evoked when confronted with a submucosal vascular laryngeal tumour. In such cases biopsies should be avoided. Exhaustive imaging is a key factor in the diagnosis and should include an MRI and an arteriography in order to rule out other differential diagnoses. To our knowledge this is the first case focusing on this issue.

Review of olfactory cleft roof anatomy.

Progress in skull-base endoscopic surgery has improved our knowledge of olfactory cleft (OC) anatomy. This article presents a review of current knowledge concerning the OC roof: descriptive anatomy, radiological exploration, and endoscopic observation. The OC is a narrow area in the most superior part of the nasal cavity. Its roof is the thinnest structure separating the nasal cavities from the brain; it comprises three superimposed tissues: nasal mucosa, ethmoid cribriform plate (ECP), and dura mater. The ECP comprises the anterior ECP containing the ethmoidal slit (ES) medially and the cribroethmoidal foramen (CEF) laterally; and the posterior ECP, comprising the olfactory foramina. The OC roof is bordered anteriorly by the nasal bone roof, laterally by the lateral ethmoid masses, and posteriorly by the jugum and anterior wall of the sphenoid sinuses. Imaging is crucial for analyzing this wall, providing precise detailed information on conformation and anatomic relations with adjacent structures such as the anterior ethmoidal artery. Understanding OC roof anatomy and correct interpretation of imaging are essential for safety in present-day functional endoscopic sinus surgery and anterior skull-base oncologic surgery.

Evaluation of the chemical model of vestibular lesions induced by arsanilate in rats.

Several animal models of vestibular deficits that mimic the human pathology phenotype have previously been developed to correlate the degree of vestibular injury to cognate vestibular deficits in a time-dependent manner. Sodium arsanilate is one of the most commonly used substances for chemical vestibular lesioning, but it is not well described in the literature. In the present study, we used histological and functional approaches to conduct a detailed exploration of the model of vestibular lesions induced by transtympanic injection of sodium arsanilate in rats. The arsanilate-induced damage was restricted to the vestibular sensory organs without affecting the external ear, the oropharynx, or Scarpa's ganglion. This finding strongly supports the absence of diffusion of arsanilate into the external ear or Eustachian tubes, or through the eighth cranial nerve sheath leading to the brainstem. One of the striking observations of the present study is the complete restructuring of the sensory epithelia into a non sensory epithelial monolayer observed at 3months after arsanilate application. This atrophy resembles the monolayer epithelia observed postmortem in the vestibular epithelia of patients with a history of lesioned vestibular deficits such as labyrinthectomy, antibiotic treatment, vestibular neuritis, or Ménière's disease. In cases of Ménière's disease, aminoglycosides, and platinum-based chemotherapy, vestibular hair cells are destroyed, regardless of the physiopathological process, as reproduced with the arsanilate model of vestibular lesion. These observations, together with those presented in this study of arsanilate vestibular toxicity, suggest that this atrophy process relies on a common mechanism of degeneration of the sensory epithelia.

Psychosocial quality of life in hereditary haemorrhagic telangiectasia patients.

OBJECTIVES: The aim of this study was to evaluate psychosocial quality of life (PQoL) in patients with Hereditary Haemorrhagic Telangiectasia (HHT). STUDY DESIGN AND SETTING: A retrospective study was performed on PQoL in HHT patients presenting with epistaxis. One hundred fifteen patients were interviewed using a questionnaire designed by two sociologists and a head and neck surgeon. Changes over time were assessed according to information on psychosocial well-being, social life, family support, occupation, and medical and demographic data regarding age, gender and patient appearance. RESULTS: Analysis of Psychosocial Quality of Life (PQoL) revealed no statistical difference in relation to gender, marital status, household income or place of residence (rural or urban); however, a significant difference was observed with age. Elderly patients had a poorer PQoL than younger patients. Workers had a better PQoL than unemployed patients. Epistaxis and professional duties were correlated: workers with less than one episode of epistaxis per month were more active. Frequent episodes of epistaxis and abundant bleeding decreased PQoL. These patients felt different and often experienced a desire to withdraw compared to others. CONCLUSION: Epistaxis in hereditary haemorrhagic telangiectasia patients was associated with the impairment of many PQoL criteria, together with relationship modifications.

[Esophageal foreign body: dental plate]. / Corps étranger esophagien: prothèse dentaire.

OBJECTIVE: Describe clinical characteristics and management of dental esophageal foreign body. PATIENT AND METHODS: Observation of a denture wedged in the esophagus in a 55 year man and literature review of cases reported in the literature. RESULTS: Enclosing risk factors for esophageal foreign body of dental origin are the altered consciousness, old persons, and local factors. The diagnosis is suspected with chest radiography and confirm by endoscopy. The therapeutic management with extraction of the foreign body is endoscopic and / or surgery. Complications a e related to time taken and can be sometimes serious. CONCLUSION: The diagnosis of esophageal dental foreign body should be considered in any dysphagia in predisposing persons. The diagnosis may require endoscopy. Prevention go through information of actors in specialized institutes.

[Bladder necrosis after an immediate post-operative mitomycin C instillation]. / Nécrose vésicale dans les suites d'une instillation postopératoire précoce (Ipop) de mitomycine C.

Administration of intravesical chemotherapy by mitomycin C decreases the risk of recurrence in non-muscle-invasive bladder tumours. We report the case of a man, who presented a full bladder necrosis after an immediate adjuvant mitomycin C instillation. The failure of resection of the necrotic area led us to perform a total cystectomy with an intestinal reconstruction. A review of the literature showed four other cases of necrosis of the bladder or of lower urinary tract. In all cases the rules of early instillation were observed.

How to identify the anterior cribriform plate in the medial approach to the frontal sinus.

Draf III frontal sinusotomy is one of the most complex surgical procedures on the frontal sinus, designed to limit the risks of restenosis by ensuring unification of the two ostia and resection of the floor of the sinus. This procedure requires a good knowledge of anatomy and sufficient surgical expertise to avoid the risk of CSF leak and to limit the risk of restenosis. The surgeon can use various landmarks, consisting of foramina, bone grooves and arteries located on the anterior part of the cribriform plate to guide the procedure. The purpose of this technical note is to explain the use of these landmarks to ensure safe Draf III frontal sinusotomy via a medial approach.

The ventrolateral surgical approach to labyrinthectomy in rats: anatomical description and clinical consequences.

UNLABELLED: Destruction of the inner ear in rats for medical research has been performed since 1936. Nevertheless, descriptions of the technique used and clinical analysis are poor and often involve coagulation of the stapedial artery. We suggest a description of a surgical ventrolateral approach to labyrinthectomy in rats, with preservation of the stapedial artery. METHODS: Twenty-five Wistar rats were operated on via a right ventrolateral approach to the bulla, followed by labyrinthectomy with preservation of the stapedial artery. Clinical observation and tests were carried out from the time of the surgery until day one. Twenty-four hours after the surgery on the right side, the same surgery was performed on the left side, followed by clinical observation. Twenty-five other rats were used as controls, with sham surgery. Histologic analysis of the vestibular nerve with silver staining was performed in six rats 3 or 7 days after the labyrinthectomy. RESULTS: The ventrolateral approach made it possible to reach the middle- and inner-ear with preservation of nervous and vascular elements such as the facial nerve and stapedial artery. Unilateral labyrinthectomy induced ocular skew deviation, head torsion and limb asymmetry. Dynamic signs were first rolling, then rotation, which increased considerably during tail suspension. Bilateral labyrinthectomy produces instability with major body oscillation. Animals show head and neck dorsiflexion with limb extension, sometimes followed by fast backward walking. CONCLUSION: The ventrolateral approach is an efficient technique for surgical labyrinthectomy with stapedial artery preservation. Clinical analysis shows a wide range of signs to evaluate the functional destruction of the vestibular organ.

[Cranial fasciitis of childhood]. / Fasciite crâniale.

OBJECTIVE: To describe the clinical and pathological features of cranial fasciitis of childhood, and to review and compare this case with those of international literature. METHODS: We report a case of cranial fasciitis of childhood located on the face of a 13-month-old boy. A complete review was performed from the database "Pub Med", looking for the key words "head and neck inflammatory myofibroblastic tumour", "nodular fasciitis", "cranial fasciitis of childhood". RESULTS: Cranial fasciitis is benign rapidly growing fibroblastic tumour, belonging to the group of nodular fasciitis, and has a predilection for the head and neck region of young children. This tumour is highly cellular and often show striking erosion of bone often misdiagnosed as a sarcoma. Surgery with adequate resection margin is the best treatment. There is no tendency for local recurrence. CONCLUSION: Positive pathological diagnosis of cranial fasciitis is uncommon and may be difficult.

[Goldman Antopol syndrome associated with bilateral congenital severe factor V deficiency]. / Syndrome d'Antopol Goldman bilatéral associé à un déficit congénital sévère en facteur V.

Antopol-Goldman lesions are extremely rare. This kind of lesion is a subepithelial pelvic hematoma. This syndrome is certainly of rare occurrence and that is why a differential diagnosis of urothelial cancer in young patients who had problems with clotting must be raised. We reported a case of a 43-year-old haemophiliac with a severe congenital factor V deficit and presenting a bilateral and asynchronous Antopol Goldman syndrome. The diagnosis has been based on CT scans. The subepithelial aetiology bleeding has been shown on selective renal arteriography that allowed to cover a micro-aneurysm through the setting up of a vascular stent and a selective embolization.

[Predictive factors and long term carcinogenic results of patients who no longer have residual tumors (stage pT0) on specimens of total cystectomy carried out for cancer of the bladder]. / Facteurs prédictifs et résultats carcinologiques à long terme des patients n'ayant plus de tumeur résiduelle (stade pT0) sur la pièce de cystectomie totale réalisée pour cancer de vessie.

AIM: The aim of our study was to evaluate predictive factors and long-term carcinogenic results for patients who had had a total cystectomy for cancer of the bladder and whose final histological results did not show evidence of a residual tumor. PATIENTS AND METHODS: From 1988 to 2002, 192 patients had a total cystectomy for a bladder tumor. No residual tumor (pT0) was evident in the specimens of cystectomy of 22 patients (11.5%). None of the patients had distant metastasis or ganglions at the time of the initial examination. RESULTS: Predictive factors for having no residual tumors based on the specimen of cystectomy (pT0) were an antecedent of neo-adjuvant chemotherapy (p=0.0079), an interval between the resection of the bladder and the cystectomy of more than 12 weeks (p=0.0014) and a resection of the initial bladder considered complete (p=0.0036). The average treatment of these 22 patients was 70+/-46 months. During treatment, two patients (9%) had a recurrence in the pelvis and 10 patients died including one from the development of his cancer of the bladder. Global, specific and non-recurrence survival at five years were 75%, 100% and 94%, respectively. We revealed better specific survival (p=0.0007) and without relapse (p<0.0001) in patients who no longer had a tumor on the specimen of cystectomy (pT0) compared with patients who had a residual tumor (pT+) but with no difference in global survival (p=0.0574). CONCLUSION: The absence of residual tumors (pT0) on a specimen of total cystectomy for cancer of the bladder was a good factor for prognosis regarding long-term survival even if tumor development was observed. Complete resection and neo-adjuvant chemotherapy probably played a beneficial role in the future of these patients.

Psychosocial quality of life in patients after total laryngectomy.

OBJECTIVES: To examine Psychosocial Quality-of Life (PSQL) changes occurring over time among patients treated for laryngeal carcinoma by total laryngectomy. METHODS: A retrospective, observational transversal study was performed on PSQL changes over time in laryngeal carcinoma patients having undergone total laryngectomy. Patients were interviewed using a questionnaire developed by two sociologists and a head and neck surgeon. Changes over time were assessed according to information with regards to smoking, alcohol consumption, psychological well-being, social life, family support, occupation and medical and demographic data regarding age, gender, verbal communication and patient appearance. POPULATION: 150 patients completed the questionnaire. All were aged over 50 years at the time of surgery (total laryngectomy). Eighty-five percent of patients were smokers and 81% drinkers. On average, the questionnaires were completed by patients 6 years after surgery. RESULTS: Before and after total laryngectomy, no statistical differences were noted for marital status (p = 1.000), frequency of dining at home with friends (p = 0.175), frequency of weekend outings (p = 0.092) or frequency of holidays (p = 0.565). A significant decrease was noted for smoking and drinking (p < 0.001), frequency of going to a café (p < 0.001), frequency of dinner outings at friends' homes (p = 0.032) and frequency of going out to a restaurant (p < 0.001). A significant increase was observed in: owning a pet (p = 0.02) and time spent watching television (p < 0.001). CONCLUSION: The two latter results are indicative of feelings of solitude among total laryngectomees. Tracheostoma and voice deprivation are limiting factors in social relationships, hence pushing individuals into withdrawal.

The uses of computer-assisted surgical navigation in trans-nasal pituitary gland surgery.

OBJECTIVES: To examine the use of computer-assisted surgery in transnasal pituitary gland surgery. PATIENTS AND METHODS: Twenty cases of transnasal pituitary gland surgery using a computer-assisted navigation system, carried out between 2002 and 2004, were retrospectively studied. The subjects consisted of 7 men and 13 women aged between 27 and 77 years of ages. The pituitary tumours included 18 macroadenomas, a microadenoma and a craniopharyngioma. Ten of the cases presented with visual field and/or visual acuity disturbances. Seven of the cases presented with endocrine disorders. A computed tomography scanner destined for navigation purposes was carried out 24 hours before the operation. The computer-assisted system used was the Digipointeur (Collin ORL) based on a system of spatial localization in electromagnetic fields. RESULTS: Tumour removal was complete in 50% of cases and partial, as judged by MRI 3 months after the procedure, in 45% of the cases. In 40% of cases, the preoperative visual disturbances had completely disappeared at 3 months. A considerable clinical improvement was observed in all of the other cases. Peroperative complications were limited to two breaches of the meninges and one peroperative hemorrhage during the excision of a macroadenoma invading the cavernous sinus, necessitating the suspension of the operation. CONCLUSION: In our experience, the use of a computer-assisted system in transseptal pituitary surgery gives reliable millimetric surgical precision in the localization of vital internal anatomical structures, optimizes surgical resection and increases levels of safety.

[Interest of peri-operative immunonutrition in head and neck cancers]. / Intérêt de l'immunonutrition péri-opératoire en carcinologie cervico-faciale.

OBJECTIVE: Authors reported the results of a study on the application of immunonutrion in peri-operative (pre and postoperative) in head and neck cancer for all patients malnourished or not. In preoperative we used an oral treatmentand in postoperative an enteral one. MATERIALS AND METHODS: Prospective study concerning 78 patients (47 malnourished versus 31 not) having had heavy head and neck curative cancerology surgery. The mean follow up was of 10 months (from 7 to 16 month). They peri-operative immuno-enriched diet consisted, in pre-operative of 1000 kcal/j during 7 days of oral immunonutrition (Impact), and in post-operative, 1500 kcal/j during 10 days of enteral immunonutition (Crucial). The nutritional state was evaluated in pre-operative by simple clinical and biological parameters (size, weight, CMI "Corporal Mass Index", albumin, NRI "Nutritional Risk Index"), and in post-operative by the evolution of the weight and the CMI. The palatability of the product used in pre-operative and the patients' compliance to the treatment are studied using the satisfaction's multiple choice question paper. RESULTS: The study showed an improvement of the patients' nutritional and general state (regain appetite, less marked asthenia) and of the quality of life. The product used in preoperative was well tolerated, this oral supplementation led to the same beneficial effects of the enteral's. At eight days in preoperative, the average weight was 62.35 kg, the average CMI was 20.93, and the average NRI was 94.12. In post-operative the patients' nutritional state improved: at eight days, the average loss of weight was 2.82 kg, the average CMI was 22.2. At one and six months after respectively the average gain of weight was 2.17 kg and 6.11 kg, the average CMI was 23.71 and 25.16. The application of this protocol decreased the post-operative complications (13% reduction of the infectious complications and 6% diminution of the fistulas). The time of hospitalization is then reduced (1.7 days), and the life's longevity is improved. CONCLUSION: The results produced by this study, demonstrate the necessity to apply a peri-operative immuno-enriched diet systematically for all the patients with and without a degraded nutritional state, undergoing a heavy head and neck curative cancerology surgery.
