[Percutaneous gastrostomy in interventional radiology in cervico-facial oncology. Apropos of 174 cases].

We report a series of 174 percutaneous gastrostomies implanted in our interventional radiology unit in patients with cancer of the upper airway and upper digestive tract: two localizations, hypopharynx and oropharynx comprised 68% of the cases (106/174). Tumor stage had reached palliative treatment in 80 cases, was in the initial phase of treatment in 57 cases and was in a sequelae phase after treatment in 37 cases. Despite problems related to anatomic modifications and tumor volume or sequelae of prior or ongoing treatment, we did not record any failures. The rate of minor complications was 15%. The one severe complication (peritonitis) required laparotomy. The duration of enteral nutrition via the gastrostomy varied from 3 weeks to more than 3 years. There were no long-term complications. We thus suggest that interventional percutaneous gastrostomy is a useful alternative to endoscopic percutaneous gastrostomy or the nasoesophageal tube, particularly in patients with voluminous tumors restricting the hypopharynx and oropharynx.

[Accelerated radiotherapy: initial results in a series of locally very advanced carcinomas of the upper respiratory and digestive tracts].

From 1992 to 1993, 46 patients with very locally advanced (74% T4) head and neck carcinomas and extensive cervical involvement (82% N2-3) were treated at the Institute Gustave Roussy with a very accelerated radiotherapy regimen: 62 Gy in three weeks with two daily 1.75 Gy fractions. Early mucosal reactions were severe but manageable in this population of patients with frequent alteration of initial performance status. Nearly every patient experienced a grade 3 or 4 (WHO) mucositis and 80% required tube feeding. Follow-up is not sufficient to draw firm conclusion about late reactions but they do not seem different from those induced by conventional radiotherapy. The overall 2-year survival rate of 49.4% and loco-regional control rate of 67% seem superior to the results of conventional radiotherapy for such advanced tumors. These results have led to a multi-center randomized controlled trial comparing this regimen of accelerated radiotherapy with conventional fractionated radiotherapy.

[Reconstruction with free jejunal graft after total circular pharyngolaryngectomy. 73 cases].

Among the various procedures of pharyngeal reconstruction after circumferential pharyngolaryngectomy, the free jejunal autograft (FJA) has become a common one. We retrospectively reviewed 73 cases of reconstruction with FJA after resection for advanced hypopharyngeal carcinomas (70 primary reconstructions, 3 secondary reconstructions). Postoperative outcome, functional and carcinologic results were studied. There were 1 postoperative death, medical complications in 19 patients, 4 graft failures (5.5%), 11 salivary fistulas. The nasogastric tube was removed before the 15th day in more than a half of the patients. One year postoperatively all the evaluable patients were able to take an oral diet (solid or soft diet for 97% of them). The postoperative radiotherapy was well tolerated. Cancer developed further in 33 patients (13 local and/or nodal recurrences, 13 isolated metastasis, 7 second primaries). The overall survival rate was 44.8% at three years. It seems clear that FJA allows good functional results and increases the quality of life in such patients with poor prognosis.

[Free bone flaps in esthetic and functional rehabilitation after segmental mandibulectomy. Apropos of 38 cases].

Development of microvascular free tissue transfers gives the surgeon the opportunity to realise complex reconstructions after segmental mandibular resections for tumor. We reviewed 38 cases of oromandibular reconstruction using various free bone grafts (25 fibula, 7 scapular, 3 iliac and 3 forearm free flaps). The mandibular defect was anterior in 24 cases, lateral in 9 cases and subtotal in 5 cases. In the post-operative course there were two total flap losses. Long-term esthetic results were excellent or good for 82% of the patients, 81% were able to eat a solid or a soft diet. The causes of esthetic or functional failures were studied as well as the specific interest of each donor site. The use of free bone flaps improved cosmetic and functional rehabilitation in cases of anterior mandibular defects. The secondary reconstructions or reconstructions of lateral bony defects were more disappointing. The free fibula flap allows reconstruction of wide bony defects. Scapular flap or forearm flap are indicated for smaller bony defects and in patients with severe peripheral vascular disease.

[The subscapular combined free flap. Original technique].

Combinations of subscapular pediculated flaps have been used in recent years. These single pedicle flaps include the latissimus dorsi, the serratus, the scapular crest and the ortho and para-scapular skin flaps. Together these flaps comprise a combined subscapular transplant. This combined flap is particularly important since the different components provide great spatial flexibility. Complex and massive pluri-tissular substance losses can thus be reconstructed. We report our work in anatomy and techniques. We found variations in the origin of the subscapular pedicle in 25% of the cases in our anatomy study (50 cases). We recommend dissection of the vascular pedicle via the axillary route first. Thus necessary adaptations can be made as a function of the variations observed. This combined flap can be removed with the patient in supine position. The fact that the position of the patient does not have to change is essential for cervicofacial surgery performed by two teams. The pedicle of the cutaneous scapular flaps is dissected starting ventrally. Since 1990, we have performed 15 combined subscapular transplantations for cervicocephalic reconstructions.

[Total esophagoplasty using a double pedicled free graft from the jejunum: the last resort].

After repeated failures of classic oesophagoplasties (gastroplasty and coloplasty) a last chance reconstruction could rely on a free jejunal transplant. We report an exceptional and original case where digestive tract was re-established between the orostoma and the epigastric antrum. The patient has four neoplasms in the throat, thoracic oesophagus. After circular pharyngolarynectomy and total oesophagectomy, all the usable vascularized plasties had necrosed. The ultimate reconstruction was performed with a free jejunal transplant carrying two vascular bundles revascularized with the cervical vessels and the internal thoracic vessels. Several recommendations are proposed: Save as much of the digestive tube as possible; preserve the physiological gastroduodenal circuit; redissect the residual plasty in order to raise the new one as high as possible; perform a sub-cutaneous insertion of the residual plasties and the jejunal transplant; and if the loss of digestive substance is greater than 30 cm, a long free jejunal transplant with two vascular bundles should be used.

Salvage surgery by composite resection for epidermoid carcinoma of the tonsillar region.

Radiation therapy has usually been used as the primary treatment of squamous cell carcinoma of the posterior aspect of the oral cavity and the lateral aspect of the oropharyngeal walls. However, local failure occurs in a certain number of cases, depending on the initial tumor stage. One hundred thirty-four composite resections (transmaxillary buccopharyngectomies) have been performed as a salvage treatment at the Institut Gustave-Roussy, Villejuif, France, from January 1, 1976, through December 31, 1985, for local failure of epidermoid carcinomas treated initially by radiotherapy. Average time between primary irradiation and salvage surgery was 18 months. Most of the patients underwent some kind of supraomohyoid neck dissection. A myocutaneous flap was used in 18% of cases, which significantly reduced the rate of local complications. The nasogastric tube and the tracheostomy cannula were removed after a median delay of 23 days and 24 days, respectively. Early postoperative local complications occurred in 45% of cases; most of them were minor. A new locoregional recurrence occurred in approximately half of the patients and was usually fatal. Overall survival after salvage surgery was 34% at 3 years and 23% at 5 years. The only statistically significant prognostic factor was the adequacy of surgical margins.

Adenoid cystic carcinoma of the head and neck: evaluation with MR imaging and clinical-pathologic correlation in 27 patients.

Twenty-seven adenoid cystic carcinomas (ACCs) of the head and neck in 27 patients were evaluated in a retrospective study based on findings at magnetic resonance (MR) imaging and pathologic and clinical examination. Clinical follow-up was obtained over a mean period of 6.3 years (range of follow-up, 3 months to 17 years); all patients underwent one to seven MR examinations. On T2-weighted images, lesions with low signal intensity corresponded to highly cellular tumors (solid subtype) with a poor prognosis; lesions with high signal intensity corresponded to less cellular tumors (cribriform or tubular subtype) with a better prognosis. MR images were not specific in differentiation of ACCs from other types of tumors; this result underscores the need for biopsy to ensure correct diagnosis. Local, intracranial, osseous, and perineural invasion was depicted, but because of its lack of specificity, MR imaging caused overdiagnosis of tumor extension, particularly perineural spread and bone abnormalities.

[Free myocutaneous flap of the latissimus dorsi in cervicofacial surgery].

Free myocutaneous latissimus dorsi transplants are exceptionally used in cervicofacial surgery. The authors have performed an anatomical study of 23 non-embalmed subjects, using injections of neoprene latex and barium sulfate into the axillary artery and dye injections. Dissections, arteriographs and corrosion show that the lower scapular pedicle is constant, with an average length of 9.5 cm and a caliber that is sufficient for vasuclar microsurgery. Eight patients with large T4 cervicocephalic neoplasms were operated, including two with tongue tumors, one with a tumor of the oropharynx, two oromandibular lesions, two lesions of the maxillary sinus and a neuroblastoma involving the middle level of the facial structures. A free myocutaneous latissimus dorsi transplant was used. The transplant was revascularised by neck vessels using microsurgical techniques. Complete success was obtained in all eight patients. Good functional, cosmetic and morphological results were obtained as a rule. In cervicofacial surgery, the authors have thus chosen and used a free myocutaneous latissimus dorsi transplant in three topographic indications: for the oropharynx, to fill large cavities, especially the maxillary sinus, and to fill the middle level of the facial structures and of the base of the skull.

[Free forearm flap used in the reconstruction of the cervico-cephalic region. 43 cases].

The free neurovascular antebrachial transplant was described by Yang-Guofan in 1978. In 1981, we brought the description of this free transplant to Europe. Forty-three antebrachial grafts were made to reconstruct the cervicocephalic extremity. We had various indications: floor of the mouth and base of the tongue: 18 cases, facial structures: 7 cases, posterior wall of the pharynx: 9 cases, rescue surgery for esophagoplasty: 6 cases, mandible: 2 cases (using a bone rod taken from the radius), internal aspect of the cheek: 1 case. All grafts were revascularized. In 41 cases, the indications were carcinological, the last 2 cases being benign lesions. The early postoperative mortality included 1 case, not related to the nature of the operation (neoplasm). There was no failure of free transplants. Surveillance was ensured every half-hour during 12 hours, then every 3 hours. Discriminating sensation was recovered in 39 of 43 cases. Mandibular bone reconstructions were knit at the 3rd month. The main disadvantage of removing this graft is esthetic, as it leaves a considerable scar on the forearm. The free antebrachial transplant provides an effective solution to the reconstructions of the cervicocephalic extremity, when a narrow, thin, supple, reinnervated, compound transplant is needed.

[Mandibular reconstruction using free vascularized fibula transplant].

Free revascularized fibular transplants have been used in surgery for the reconstruction of long bones since 1973. The reconstruction of the mandible using a free fibular transplant has been published in 1989 only by Hidalgo. The mandible and the fibula have little in common, except for their length and a similar structure in section. The anatomical study of the free osteofasciocutaneous fibular graft included 20 fresh subjects. The vascularization of the fasciocutaneous plate is either grouped or, more frequently, tiered (2/3 of cases). The technique to remove this graft is specified. Four clinical cases are reported, including three cases of neoplasm of the floor of the mouth invading the mandible, and one case of traumatic amputation of the lower part of the face. A free composed transplant taken from the fibula has been used in all four cases. The postoperative period was normal, and the grafts were completely successful. The main indications of free transplants made of fibular bone are: extensive (more than 8 cm) or compound losses of bony substance from the mandible. The richly vascularized transplant take from the fibula is very sophisticated and performant. The length of bone that can be removed is 25 cm; the bone may be osteotomized in 2 to 4 fragments retaining their vitality. Other tissular structures such as the skin, fascia, muscle, are removed with the bone. The independence in space is threefold and regards the bone, the teguments and the vascular pedicle. The microsurgical qualities of the vascular pedicle are considerable. These free transplants improve the quality of survival (endosseous implants in one case). The morphological, functional and esthetic result is good as a rule.

[Salvage esophagoplasty using free jejunal transplant after repeated failure of other esophagoplasties. 25 cases].

Salvage oesophagoplasty using a free jejunal transplant is the ultimate reconstruction possible after repeated failures using the classic procedures of oesophagoplasty. The free jejunal transplant appears to be the best choice. Twenty-five free jejunal transplants were performed by the same surgeon for such reconstructions including 13 cases involving benign lesions and 12 cases of cancer. There were no post-operative death and none of the transplantations was a complete failure although three cases of stenosis and fistulization occurred. Several recommendations can be made: save the existing digestive tract, redissect the residual digestive plasty and pull it up. The residual digestive flap can be examined by opacification or endoscopically in order to evaluate its length. An arteriography of the pediculated plasty gives information on its vascularization. A free jejunal graft can safely cover 25 to 30 cm. When possible, residual plasties should be positioned subcutaneously. The reconstruction of the cervico-thoracic oesophagus usually requires a vascular bypass with a saphene graft. In difficult cases, it may be necessary to remove a part of the sternal manubrium and the head of the clavicular bone in order to avoid compressing the jejunal graft. When the length of the reconstruction is greater than 30 cm, a long jejunal transplant with two pedicules (1 pedicule revascularized from the cervical vessels and the other pedicule from the internal thoracic vessels) is needed. An alternative technique would be a free antebrachial flap (six cases operated with two post-operative deaths at 6 weeks and two fistulas).(ABSTRACT TRUNCATED AT 250 WORDS)

[Tumors of the mandible. Justification of a second reconstruction after recurrence on the first revascularized bone graft].

The use of free vascularized bone grafts for mandibular reconstruction has led to a consideration of the new entity of recurrent tumour on bone grafts. Exeresis of the mandible was performed in 4 patients with bone tumours: osteosarcoma 1, osteochondroma 1, carcinoma 1 and ameloblastoma 1. A free vascularized bone graft was used for the reconstruction. Tumours recurred with a delay of 10 to 18 months after the initial reconstruction. The frequency of tumoural recurrence can be measured in our series of 46 patients (24 with fibular grafts, 15 with scapular grafts, 4 with radius grafts and 3 with iliac bone grafts). Recurrence rate at our institution was 4.3%. The 2 other cases involved patients from other institutions. The main factor involved in tumoural recurrence is the aggressive nature of the primary tumours, even after extensive initial resection as performed in our patients. Free bone grafts were invaded as were neighbouring tissues. Secondary reconstruction of the mandible was performed in 3 cases with a fibula graft. In the fourth patient, no operation was possible due to the diffuse nature of the invasion and the poor status of the patient's vessels and general health. Local extension, and not the tumour histology, is the main factor in deciding upon reoperation. The explosive nature of recurrences is linked more to the aggressive character of the tumour than to the status of the revascularized free bone graft. Secondary reconstruction is justified after recurrence on bone grafts depending on the complexity of the major resection involving extensive tissue exeresis.(ABSTRACT TRUNCATED AT 250 WORDS)

[Posterior pharyngectomy. Reconstruction using a free antebrachial transplant].

Cancers of the posterior wall of the oro or hypopharynx are rare and do not invade the larynx or the oesophageal orifice. Previously, these cancers were treated with radiotherapy alone, but since 1981 new techniques in reconstruction surgery have allowed a surgical approach. Cancerological non-mutilating exeresis is possible, but reconstruction is difficult since the flap must be very thin to allow normal food intake. In addition, flap reliability is extremely important due to the gravity of cervical salivary fistulation. We treated 15 patients with a lesion of the posterior wall of the pharynx using posterior pharyngectomy and reconstruction with a free antebrachial transplant which was revascularized and reinnervated. In two cases, the operation was performed in patients who had had previous radiotherapy. A branch of the external carotid and the internal jugular vein were used for vascular microanastomoses and reinnervation was obtained using the superficial cervical plexus. The transplant was placed over the prevertebral aponevrosis and sutured to the remaining pharyngeal mucosa. One postoperative death due to heart disease occurred at D + 11. All reconstructions were successful and two salivary fistulas on irradiated tissue closed spontaneously. Postoperative radiotherapy was performed in 11 cases (50-65 Gy) and was well tolerated. These results demonstrate that a highly flexible and thin free forearm transplant is perfectly adapted to reconstruction after posterior pharyngectomy. It is more reliable than local pediculated flaps.

[Multiple free transplants in microsurgery for cervicofacial reconstruction].

Microsurgical techniques open the way for much creativity and originality for cervicofacial reconstruction and tumoral repair. Between 1976 and 1994, we performed 481 free transplants for cervico-facial reconstruction. A recently developed strategy has been the use of multiple free transplants, either simultaneously or successively. Between 1990 and 1994, we operated and reconstructed 9 patients using multiple free cervico-cephalic transplants after multitissular and agressive exeresis for tumoral or traumatic lesions. In 3 cases, the transplants were made simultaneously and in the 6 others successively. Three patients received 3 free transplants and 6 patients had 2. In 8 cases, each of the transplants was micro-anastomosed on different vessels. In one case, the two transplants were anastomosed in series, the most distal portion being connected to the most proximal portion (in comparison with the cervical vessels). One death occurred at 6 weeks due to infectious complications. The final result for the 8 other patients was good both morphologically and functionally. Indications for multiple free transplants include: complex tissue loss, multiple and massive tissue loss of the cervicocephalic region. This situation occurs particularly in case of voluminous tumours invading several structures, in multiple tumours and in firearm wounds. These series of patients allowed a definition of recommended techniques in case of difficulties in these very elaborate surgical procedures and confirmed that if the strategy is correctly planned, it is possible to greatly improve the quality of survival in these patients in terms of aesthetics, morphology and function.
