Surgical management of hemorrhage from rupture of the aortic arch.

BACKGROUND: Control of hemorrhage in patients with active bleeding from rupture of the aortic arch is difficult, because of the location of the bleeding and the impossibility of cross-clamping the aorta without interfering with cerebral perfusion. A precise and swift plan of management helped us salvage some patients and prompted us to review our experience. METHODS: Six patients with active bleeding of the aortic arch in the mediastinum and pericardial cavity (5 patients) or left pleural cavity (1 patient), treated between 1992 and 1996, were reviewed. Bleeding was reduced by keeping the mediastinum under local tension (3 patients) or by applying compression on the bleeding site (2 patients), or both (1 patient) while circulatory support, retransfusion of aspirated blood, and hypothermia were established. The diseased aortic arch was replaced during deep hypothermic circulatory arrest, which ranged from 25 to 40 minutes. In 3 patients, the brain was further protected by retrograde (2 patients) or antegrade (1 patient) cerebral perfusion. RESULTS: Hemorrhage from the aortic arch was controlled in all patients. Two patients died postoperatively, one of respiratory failure and the other of abdominal sepsis. Recovery of neurologic function was assessed and complete in all patients. The 4 survivors are well 8 to 49 months after operation. CONCLUSIONS: An approach relying on local tamponade to reduce bleeding, rapid establishment of circulatory support and hypothermia, retransfusion of aspirated blood, and swift repair of the aortic arch under circulatory arrest allows salvage of patients with active bleeding from an aortic arch rupture.

Prise en charge des troubles oculomoteurs après effraction iatrogène de l'orbite au cours d'interventions sinusiennes endoscopiques [Management of motility disorders secondary to iatrogenic orbital fracture during endoscopic sinus surgery.]

PURPOSE: Orbital wall fracture may occur during endoscopic sinus surgery, resulting in oculomotor disorders. We report the management of four cases presenting with this surgical complication. METHODS: A non-comparative observational retrospective study was carried out on four patients presenting with diplopia after endoscopic ethmoidal sinus surgery. All patients underwent full ophthalmologic and orthoptic examination as well as orbital imaging. RESULTS: All four patients presented with diplopia secondary to a medial rectus lesion confirmed by orbital imaging. A large horizontal deviation as well as limitation of adduction was present in all cases. Surgical management consisted of conventional recession-resection procedures in three cases and muscle transposition in one patient. A useful field of binocular single vision was restored in two of the four patients. CONCLUSION: Orbital injury may occur during endoscopic sinus surgery and cause diplopia, usually secondary to medial rectus involvement due to the proximity of this muscle to the lamina papyracea of the ethmoid bone. Surgical management is based on orbital imaging, duration of the lesion, evaluation of anterior segment vasculature, results of forced duction testing and intraoperative findings. In most cases, treatment is aimed at the symptoms rather than the cause, and the functional prognosis remains guarded.

Successful surgical resection in non-lesional operculo-insular epilepsy without intracranial monitoring.

Pre-operative assessment and surgical management of patients with non-lesional extratemporal epilepsy remain challenging due to a lack of precise localisation of the epileptic zone. In most cases, invasive recording with depth or subdural electrodes is required. Here, we describe the case of 6.5-year-old girl who underwent comprehensive non-invasive phase I video-EEG investigation for drug-resistant epilepsy, including electric source and nuclear imaging. Left operculo-insular epilepsy was diagnosed. Post-operatively, she developed aphasia which resolved within one year, corroborating the notion of enhanced language plasticity in children. The patient remained seizure-free for more than three years.

A Multicenter Randomized Clinical Trial of Primary Anastomosis or Hartmann's Procedure for Perforated Left Colonic Diverticulitis With Purulent or Fecal Peritonitis.

OBJECTIVES: : To evaluate the outcome after Hartmann's procedure (HP) versus primary anastomosis (PA) with diverting ileostomy for perforated left-sided diverticulitis. BACKGROUND: : The surgical management of left-sided colonic perforation with purulent or fecal peritonitis remains controversial. PA with ileostomy seems to be superior to HP; however, results in the literature are affected by a significant selection bias. No randomized clinical trial has yet compared the 2 procedures. METHODS: : Sixty-two patients with acute left-sided colonic perforation (Hinchey III and IV) from 4 centers were randomized to HP (n = 30) and to PA (with diverting ileostomy, n = 32), with a planned stoma reversal operation after 3 months in both groups. Data were analyzed on an intention-to-treat basis. The primary end point was the overall complication rate. The study was discontinued following an interim analysis that found significant differences of relevant secondary end points as well as a decreasing accrual rate (NCT01233713). RESULTS: : Patient demographics were equally distributed in both groups (Hinchey III: 76% vs 75% and Hinchey IV: 24% vs 25%, for HP vs PA, respectively). The overall complication rate for both resection and stoma reversal operations was comparable (80% vs 84%, P = 0.813). Although the outcome after the initial colon resection did not show any significant differences (mortality 13% vs 9% and morbidity 67% vs 75% in HP vs PA), the stoma reversal rate after PA with diverting ileostomy was higher (90% vs 57%, P = 0.005) and serious complications (Grades IIIb-IV: 0% vs 20%, P = 0.046), operating time (73 minutes vs 183 minutes, P < 0.001), hospital stay (6 days vs 9 days, P = 0.016), and lower in-hospital costs (US $16,717 vs US $24,014) were significantly reduced in the PA group. CONCLUSIONS: : This is the first randomized clinical trial favoring PA with diverting ileostomy over HP in patients with perforated diverticulitis.

Spontaneous subconjunctival orbital fat prolapse: presentation of four cases

BACKGROUND: Subconjunctival orbital fat prolapse is a benign entity characterized by orbital fat herniation through a dehiscence in Tenon's capsule, usually between the superior and lateral recti muscles. It is often associated with ocular trauma or surgery, although spontaneous cases have also been reported with a predilection for obese individuals. PATIENTS AND METHODS: A retrospective study of four subconjunctival orbital-fat prolapse cases with no history of ocular surgery or trauma was performed. A trans-conjunctival surgical approach with Tenon's capsule repair was offered to all subjects. Differential diagnosis is discussed. RESULTS: The diagnosis of subconjunctival orbital fat prolapse was confirmed in all cases by histopathological examination. Functional and aesthetic postoperative results were excellent, with no recurrences during follow-up, for all cases. CONCLUSIONS: Although rare, subconjunctival orbital fat prolapse should be recognized. Surgical management offers excellent results.

Conjunctival intraepithelial neoplasia in a patient treated with tacrolimus after liver transplantation.

PURPOSE: To report a case of conjunctival intraepithelial neoplasia in a patient treated with tacrolimus after liver transplantation for hepatic carcinoma. METHODS: Description of the initial clinical presentation of a patient, tumor management, and 15-month follow-up. RESULTS: A 70-year-old man presented with a conjunctival intraepithelial neoplasia that developed on the site of a preexisting pterygium. After total surgical removal and additional application of mitomycin, local tumor control was achieved. CONCLUSIONS: We describe a case of intraepithelial conjunctival neoplasia in a patient treated with systemic tacrolimus. Local tumor control was achieved at 15 months after appropriate surgical management.

Systematic review and meta-analysis of risk factors for survival after lung metastasectomy in colorectal cancer patients

Objective: Resection of lung metastases (LM) from colorectal cancer (CRC)¦is increasingly performed with a curative intent.Most series report small groups¦of patients, and it is currently not possible to identify those CRC patients who¦may benefit the most of surgical management. It is clinically relevant to assess¦risk factors for prolonged survival after this type of procedures.¦Methods: A meta analysis of 24 series published between 2000 and 2011¦which focused on surgical management of LM from CRC and included more¦than 40 patients each, with or without prior resection of in transit liver¦metastases. Random effects were calculated for five variables considered as¦potential prognostic factors.¦Results: A total of 2815 patients who underwent surgery with a curative¦intent were considered in this analysis. Four parameters were associated with¦a decreased survival: 1) a short disease-free interval between primary tumor¦resection and development of LM (HR = 1·59, 95% CI 1·27-1·98); 2) multiple¦LM (HR = 2·04, 95%CI 1·72-2·41); 3) positive hilar/mediastinal lymph nodes¦(HR = 1·65, 95% CI 1·35-2·02); and 4) a high prethoracotomy CEA value (HR¦=1·91, 95% CI 1·57-2·32). By comparison, a history of resected liver metastases¦(HR = 1·36, 95% CI 0·92-2·03) did not achieve statistical significance.¦Conclusion: Risk factors for poor clinical outcome after surgery for lung¦metastases in CRC patients include: 1) synchronous lung metastases; 2) high¦pre-thoracotomy CEA; 3) hilar nodes involvement; and 4) multiple pulmonary¦lesions.

Intérêt d'une Consultation spécialisée multidisciplinaire en neuro-urologie et urologie fonctionnelle [Benefit of a specialized multidisciplinary clinic in neuro-urology and functional urology].

Functional disorders encounter for a large amount of the medical activity, including in urology. The decreased quality of life due to lower urinary tract symptoms requires a prompt management, with primary assessment undergone in community. Referral to a specialist is required when simple management has failed, and whenever any of these coexists: hematuria, recurrent urinary infection, and neurological condition. The specialized clinic in neurourology and functional urology aim at further investigating the underlying disorder responsible for the urinary symptoms and preventing urinary tract complications. A multidisciplinary team is the key to accurately assess patients with regards to their bother and handicap, therefore offering the most appropriate conservative, medical or surgical management.

Acute ulcerative jejunal diverticulitis: case report of an uncommon entity.

Jejunal diverticulosis is a rare entity with variable clinical and anatomical presentations. Its reported incidence varies from 0.05% to 6%. Although there is no consensus on the management of asymptomatic jejunal diverticular disease, some complications are potentially life threatening and require early surgical treatment. We report a case of an 88-year-old man investigated for acute abdominal pain with a high biological inflammatory syndrome. Inflammation of multiple giant jejunal diverticulum was discovered at abdominal computed tomography (CT). As a result of the clinical and biological signs of early peritonitis, an emergency surgical exploration was performed. The first jejunal loop showed clear signs of jejunal diverticulitis. Primary segmental jejunum resection with end-to-end anastomosis was performed. Histopathology report confirmed an ulcerative jejunal diverticulitis with imminent perforation and acute local peritonitis. The patient made an excellent rapid postoperative recovery. Jejunal diverticulum is rare but may cause serious complications. It should be considered a possible etiology of acute abdomen, especially in elderly patients with unusual symptomatology. Abdominal CT is the diagnostic tool of choice. The best treatment is emergency surgical management.

Colorectal cancer and thoracic surgeons: close encounters of the third kind.

Resection of lung metastases from colorectal cancer (CRC) is increasingly performed with a curative intent. This strategy was made possible in the 1990s by the development of new chemotherapeutic approaches, improved surgical techniques and better imaging modalities. However, evidence-based data showing clinical benefits of lung metastasectomy in this setting are nonexistent, and there are no prospective randomized trials to support the routine performance of these procedures for stage IV CRC. Current evidence suggests that resection of pulmonary metastases in combination with new cytotoxic agents, such as oxaliplatin, irinotecan and bevacizumab, may result in prolonged survival for many, and cure for a small minority of CRC patients who experienced tumor spread beyond the limits of the abdomen. This review focuses on the results of surgical management of CRC patients with lung metastases: we report the outcome of published series according to the presence or the absence of liver metastasis (and hepatic resection) prior to lung resection.

Quand faut-il opérer une fracture isolée du tiers moyen de la clavicule [When to operate an isolated midshaft clavicle fracture?]

Slightly displaced clavicular midshaft fracture is currently treated nonoperatively. There is considerable debate about whether acute displaced fractures should be treated operatively. Nonunion rate after displaced fracture has been underestimated for a long time, and malunion clinical impact often minimized. It is known that operative treatment decreases these rates. However, operating all displaced fractures may lead to overtreatment. Acute operative treatment of midshaft fractures with delayed treatment of established nonunion showed no significant difference in the outcome, but malunion surgical management is technically demanding. Consequently these fractures could be treated surgically, but operative indication should be adapted to patient expectations.

The infected aorta.

BACKGROUND: Despite the improvements achieved in antibiotic therapy, severe aortic infection resulting in mycotic aneurysms is still a highly lethal disease and surgical management remains a challenging task. PATIENTS AND METHODS: A total of 43 patients with severe aortic infections were analyzed and separated in four groups: (1) Infections of the aortic root Ventriculo-aortic disconnection due to deep aortic infection (6 patients). Two patients were operated using homo-composit grafts. Of the 6 patients total, one died early and two died late during a mean follow-up of 6 years. The two patients with homografts are still alive. (2) Infections of the ascending aorta and the aortic arch. In situ repair for mycotic aneurysmal lesions of the ascending aorta was performed in 6 patients using synthetic graft material in 4/6, biological material in 1/6 and direct suture in 1/6. Two patients had to be reoperated; one of them died early. There was no recurrent infection during a mean follow-up of 6 years. (3) Infections of the descending thoracic and thoraco-abdominal aorta in-situ repair for mycotic aneurysmal lesions of the descending and thoraco-abdominal aorta was performed in 12 patients using homografts in five. Two patients died early and two other patients died late during a mean follow-up of 6 years. (4) Infections of the infrarenal abdominal aorta. In this series of 19 patients with mycotic infrarenal aortic aneurysms, in situ reconstruction was performed in 12 (5/12 with homografts) and extra-anatomic reconstruction (axillo-femoral bypass) was performed in 7. Hospital mortality was 5/19 patients and another 5/19 patients died during a mean follow-up of 6 years. One of the early deaths was due to aortic stump rupture. Two patients with axillo-femoral reconstructions were later converted to descending-thoracic-aortic-bifemoral bypasses. Five thromboses of axillo-femoral bypasses were observed in three of the seven patients with extra-anatomic repairs. RESULTS: Infections of the aortic root, the ascending aorta and the aortic arch are approached with total cardio-pulmonary bypass, using cardioplegic myocardial protection and deep hypothermia with circulatory arrest if necessary. Proximal unloading and distal support using partial cardiopulmonary bypass is preferred for repair of infected descending and thoracoabdominal aortic lesions, whereas no such adjuncts are required for repair of infected infrarenal aortic lesions. CONCLUSIONS: The anatomical location of the aortic infection and the availability of homologous graft material are the main factors determining the surgical strategy.

Role of surgery in pediatric epilepsy.

Twenty five percent of patients with intractable epilepsy have surgically remediable epilepsy syndromes. This article reviews the treatment paradigm for pediatric epilepsy and also the indications, methods, and surgical options for the subgroup of patients with surgically remediable epileptic disorders based on our experience in the management of these children. The article also discusses the rationale for offering surgery and the timing of surgery in these patients. The study of surgically remediable epilepsy can best be divided into focal, sub hemispheric, hemispheric and multifocal epileptic syndromes. These syndromes have both acquired and congenital etiologies and can be treated by resective or disconnective surgery. The surgical management of these conditions (with the exception of multifocal epilepsy) provides Engel's Class 1 outcome(complete seizure freedom) in approximately 80% of children. The consequences of seizure freedom leads to a marked improvement in the quality of life of these children. The benefits to society, of allowing a child to grow to adulthood with normal cognition to earn a livelihood and contribute actively to society, cannot be understated.
