Abstract: Objective: T4-disease for non-small cell lung cancer (NSCLC) includes different conditions: mediastinal invasion, neoplastic pleural cytology, and multifocal disease in the same lobe; regarding the last category, no strict criteria allow to differentiate satellite nodules from synchronous multiple primary tumours. Methods: Retrospective study of 56 patients who underwent a complete resection from 1985 to 2006 of a NSCLC graded pT4N0 due to multifocal disease. A small nodule (<1cm) closed to the primary tumour, in a same pulmonary segment with an identical histology was considered as a satellite nodule (pT4sn). Multiple tumours, sized more than 1cm, with an identical histology, located in the same lobe but in different segment were considered as synchronous cancers (pT4sc). Results: There were 44 males and 12 females: 35 patients were graded T4sn and 21 patients T4sc. The median age was 62.5 years. The two groups were similar for sex, age, tobacco consumption, ASA score, NYHA, Charlson''s index, spirometric parameters, cardiovascular comorbidity and history of previous extra-thoracic malignancies. All had a complete anatomic resection with mediastinal lymphadenectomy. Thirty-day mortality rate was 3.6%. Overall 5-year and 10-year survival rates were 48.2% and 29.9%, respectively. There was a non-significant trend for a worse survival in T4sn group patients when compared to that of T4sc group patients: 42.9% vs 52.3% at 5 years, and 25% vs 34.9% at 10 years (p =0.62). Conclusions: Multifocal T4 stage IIIB disease is a heterogeneous category where overall prognosis is far better than those of other T4 subgroups. Survival rates associated with pT4sn and pT4sc look roughly similar because of the small size of the subgroups usually submitted to comparison in most series. In the present experience, respective survival figures diverge, suggesting different biological behaviours. [Copyright &y& Elsevier]

Introduction: To prepare military doctors to face mass casualty incidents (MCIs), the French Army Health Service contributed to the development of TRAUMASIMS, a serious game (SG) for training medical responders to MCIs., Methods: French military doctors participated in a three-phase training study. The initial war trauma training was a combination of didactic lectures (Phase 1), laboratory exercises (Phase 2), and situational training exercises (STX) (Phase 3). Phase 1 lectures reviewed French Forward Combat Casualty Care (FFCCC) practices based on the acronym MARCHE (Massive bleeding, Airway, Respiration, Circulation, Head, hypothermia, Evacuation) for the detection of care priorities and implementation of life-saving interventions, triage, and medical evacuation (MEDEVAC) requests. Phase 2 was a case-control study that consisted of a traditional text-based simulation of MCIs (control group) or SG training (study group). Phase 3 was clinical: military students had to simultaneously manage five combat casualties in a prehospital setting. MCI management was evaluated using a standard 20-item scale of FFCCC benchmarks, 9-line MEDEVAC request, and time to evacuate the casualty collection point (CCP). Emotional responses of study participants were secondarily analyzed., Results: Among the 81 postgraduate military students included, 38 took SG training, and 35 trained with a text-based simulation in Phase 2. Regarding the error rates made during STX (Phase 3), SG improved FFCCC compliance (11.9% vs. 23.4%; p < .001). Additionally, triage was more accurate in the SG group (93.4% vs. 88.0%; p = .09). SG training mainly benefited priority and routine casualties, allowing faster clearance of the CCP (p = .001). Stress evaluations did not demonstrate any effect of immersive simulation., Conclusion: A brief SG-based curriculum (2 hours) improved FFCCC performance and categorization of casualties in MCI STX., (2023.)

Background: This study reports the challenges faced by French military surgeons in the management of thoracic injury during the latest Afghanistan war., Methods: From January 2009 to April 2013, all of the civilian, French and Coalition casualties admitted to French NATO Combat Support Hospital situated on Kabul were prospectively recorded in the French Military Health Service Registry (OPEX(®)). Only penetrating and blunt thoracic trauma patients were retrospectively included., Results: Eighty-nine casualties were included who were mainly civilian (61%) and men (94%) with a mean age of 27.9 years old. Surgeons dealt with polytraumas (78%), severe injuries (mean Injury Severity Score=39.2) and penetrating wounds (96%) due to explosion in 37%, gunshot in 53% and stabbing in 9%. Most of casualties were first observed or drained (n=56). In this non-operative group more than 40% of casualties needed further actions. In the operative group, Damage Control Thoracotomy (n=22) was performed to stop ongoing bleeding and air leakage and Emergency Department Thoracotomy (n=11) for agonal patient. Casualties suffered from hemothorax (60%), pneumothorax (39%), diaphragmatic (37%), lung (35%), heart or great vessels (20%) injuries. The main actions were diaphragmatic sutures (n=25), lung resections (wedge n=6, lobectomy n=4) and haemostasis (intercostal artery ligation n=3, heart injury repairs n=5, great vessels injury repairs n=5). Overall mortality was 11%. The rate of subsequent surgery was 34%., Conclusions: The analysis of the OPEX(®) registry reflects the thoracic surgical challenges of general (visceral) surgeons serving in combat environment during the latest Afghanistan War., (Copyright © 2016 Elsevier Ltd.

Objective: The goal of the study is to report the short- and long-term outcome of a left approach in the management of type III and IV hiatal hernia., Methods: We have retrospectively reviewed all the records of patients treated for type III and IV hiatal hernia with a left transthoracic approach. All the patients were evaluated before and after the surgery on clinical presentation, symptoms and functional assessment. We have specifically focused the evaluation on surgical results, mortality, morbidity and long term functional assessment., Results: Sixty-five patients were included in this study. Type III hiatal hernia (86%) were majority compared to type IV(14%). Surgical techniques included Nissen fundoplication (37%), Collis Nissen elongation gastroplasty (20%) and Belsey-Mark IV (15%). Morbidity was low and there was no hospital mortality. Mean follow-up was 42 months. Long-term reassessment demonstrated a significant improvement of symptoms. Erosive esophagitis persisted in one patient (P < 0.001). Pressure at the level of lower esophageal sphincter was normal in all patients. 24-hours pH-metry was normal in 92% of patients. Anti-acid medication was reduced significantly (P < 0.001)., Conclusion: Obesity, short esophagus, massive hiatal hernia, associated oesophageal diseases or previous failed surgery constituted the indications of choice for transthoracic approach. This procedure gives satisfactory functional and anatomical long term results with healing of mucosal damage.

The choice of the colon as an oesophageal substitute results primarily from the unavailability of the stomach. However, given its durability and function, colon interposition keeps elective indications in patients with benign or malignant oesophageal disease who are potential candidates for long survival. The choice of the colonic portion used for oesophageal reconstruction depends on the required length of the graft, and the encountered colonic vascular anatomy, the last being characterised by the near-invariability of the left colonic vessels, in contrast to the vascular pattern of the right side of the colon. Accordingly, the transverse colon with all or part of the ascending colon is the substitute of choice, positioned in the isoperistaltic direction, and supplied either from the left colic vessels for long grafts or middle colic vessels for shorter grafts. Technical key points are: full mobilisation of the entire colon, identification of the main colonic vessels and collaterals, and a prolonged clamping test to ensure the permeability of the chosen nourishing pedicle. Transposition through the posterior mediastinum in the oesophageal bed is the shortest one and thereby offers the best functional results. When the oesophageal bed is not available, the retrosternal route is the preferred alternative option. The food bolus travelling mainly by gravity makes straightness of the conduit of paramount importance. The proximal anastomosis is a single-layer hand-fashioned end-to-end anastomosis to prevent narrowing. When the stomach is available, the distal anastomosis is best performed at the posterior part of the antrum for the reasons of pedicle positioning and reflux prevention, and a gastric drainage procedure is added when the oesophagus and vagus nerves have been removed. In the other cases, a Roux-en-Y jejunal loop is preferable to prevent bile reflux into the colon. Additional procedures include re-establishment of the colonic continuity, a careful closure of the mesentery to avoid a further internal hernia, and routine appendectomy. When applying these technical aids, the chances of achieving a viable and well-functioning colon graft are excellent.

Authors report a case of a 31 years old patient who eliminate a urinary stone which contains a platinium coil. Five years ago, this patient had a percutaneous nephrolithotomy. A persistent hematuria was successfully managed with angioembolization of a lower polar artery branch. One of the coils was deployed too distally. It was not efficient, it rolled itself up in the pseudoaneurysm cavity. Different physio pathological hypothesis are developed to explain this expulsion.

Background: Long-term outcome of patients treated for a spontaneous esophageal rupture (Boerhaave's syndrome) is seldom reported., Methods: From 1989 to 2004, 62 esophageal perforations were treated in a single institution. Eighteen patients presented with a spontaneous esophageal rupture. Among them, 15 could be treated with a transthoracic primary repair and constituted the material of the present study. A chart review was performed with special attention to survival, residual symptoms, and anatomic and motility disorders., Results: Three patients died postoperatively (20%). At last follow-up, 10 patients were alive and 2 had died from unrelated causes. At a median delay of 13 months (3 to 74), 7 patients accepted to undergo complementary investigations. None of them had any anatomic abnormality as checked by barium swallow. Six patients complained of mild symptoms from gastroesophageal reflux. Six patients (85%) presented with esophageal motility disorders on manometry and 4 (54%) had nocturne chronic reflux disease on pH monitoring. Two patients underwent endoscopic ultrasonography, of which one presented with a focal absence of one layer of the esophageal wall within the area of the suture. With time, no patient experienced recurrence, but one developed a cancer in the cervical esophagus., Conclusions: These results suggest that esophageal functional disorders are the rule after primary repair of a Boerhaave's syndrome. Whether or not these findings are causal, coincidental, or related to the surgical treatment remains unclear. However, performance of routine postoperative explorations is strongly encouraged for a better understanding of this challenging condition.
