Inferior mesenteric vein as initial landmark for laparoscopic medial to lateral dissection of descending colon - a video vignette
2017
The root of the inferior mesenteric artery is an important area where autonomic nerves are close by, the dissection can be hard and laborious in order to avoid nerve damage; and the separation of mesocolon and retroperitoneum in this area can sometimes be difficult. The inferior mesenteric vein dissection is an alternative option as the first step during medial to lateral approach of laparoscopic left mesocolon mobilisation, as we have shown in this video based on two real cases and two anatomical cadaveric dissection.

Evidence, Lack of Evidence, Controversy, and Debate in the Provision and Performance of the Surgery of Acute Type A Aortic Dissection
2011
Acute type A aortic dissection is a lethal condition requiring emergency surgery. It has diverse presentations, and the diagnosis can be missed or delayed. Once diagnosed, decisions with regard to initial management, transfer, appropriateness of surgery, timing of operation, and intervention for malperfusion complications are necessary. The goals of surgery are to save life by prevention of pericardial tamponade or intra-pericardial aortic rupture, to resect the primary entry tear, to correct or prevent any malperfusion and aortic valve regurgitation, and if possible to prevent late dissection-related complications in the proximal and downstream aorta. No randomized trials of treatment or t…
Skip metastases to lateral cervical lymph nodes in differentiated thyroid cancer: a systematic review.
2019
Abstract Papillary thyroid carcinoma is a slow-growing cancer with a generally good prognosis that sometimes have an aggressive behaviour. Metastases to neck lymph nodes is the first step of the diffusion. The central neck compartment is involved most commonly. The ipsilateral lateral neck compartments are usually involved afterwards, and the involvement of the contralateral one is considered a quite rare occurrence. In more rare cases, metastases to lateral neck compartment without central lymph node metastasis (so called “skip metastases”) could be observed. Aim of this literature review study is to analyse the average incidence, pattern and risk factors of this occurrence. This study was…
Peut-on proposer un prélèvement du ganglion sentinelle en cas de chimiothérapie néoadjuvante dans les cancers du sein et à quel moment ?
2016
The main goal of preoperative chemotherapy is to reduce the size of the tumor and allow conservative treatment. Neoadjuvant treatment can affect axillary status with a downstaging in one third of the cases. For these patients, the benefit of axillary node dissection is questioned and the sentinel node biopsy (SLNB) seems to be a relevant option. However, the timing of performing SLNB is still debated especially for clinical negative patients with negative axillary ultrasound before preoperative chemotherapy. For axillary positive nodes proved by biopsy/cytology before preoperative chemotherapy, SLNB can be an option if there is a good clinical and radiological response.

Sonography and computed tomography are used in staging of lymph nodes of patients with head and neck cancer. The accuracy of sonography (90%) and computed tomography (85%) is comparable or better than the palpatory accuracy (85%). The better delineation of reactive swollen cervical nodes leads to a higher sensitivity of sonography (90%) and computed tomography (84%) versus palpation (74%), but a lower specifity (palpation 94%, sonography 90%, computed tomography 86%). A literature survey shows that sonography, computed tomography and magnetic resonance imaging of cervical lymph nodes are comparable good methods.
Does the origin of ablated premature ventricular contractions determine the level of left ventricular function improvement?
2020
Background: Premature ventricular contractions (PVCs) are associated with tachycardiomyopathy and high mortality rate. The treatment depends on the engaged ventricle. For PVCs originating from the right outflow tract (OT), radiofrequency catheter ablation (RFCA) is recommended (class IB‑R recommendation) in preference to pharmacotherapy. In those originating from the left ventricle, ablation is a class IIa B‑NR recommendation. Aims: The aim of the study was to assess the success of RFCA of PVCs based on arrhythmia origin. Methods: A total of 110 consecutive patients with monomorphic PVCs referred for ablation were enrolled and divided according to the site of ablation to the OT group and th…
Alterations in 18F-FDG accumulation into neck-related muscles after neck dissection for patients with oral cancers
2015
Background: 18 F-fluoro-2-deoxy-D-glucose ( 18 F-FDG) accumulations are commonly seen in the neck-related muscles of the surgical and non-surgical sides after surgery with neck dissection (ND) for oral cancers, which leads to radiologists having difficulty in diagnosing the lesions. To examine the alterations in 18 F-FDG accumulation in neck-related muscles of patients after ND for oral cancer. Material and Methods: 18 F-FDG accumulations on positron emission tomography (PET)-computed tomography (CT) in neck-related muscles were retrospectively analyzed after surgical dissection of cervical lymph nodes in oral cancers. Results: According to the extent of ND of cervical lymph nodes, the rate…
A multicenter cohort study to compare quality of life in breast cancer patients according to sentinel lymph node biopsy or axillary lymph node dissec…
2009
Background: This prospective multicenter study assessed and compared the impact of different surgical procedures on quality of life (QoL) in breast cancer patients. Patients and methods: The EORTC QLQ-C30 and the EORTC QLQ-BR-23 questionnaires were used to assess global health status (GHS), arm (BRAS) and breast (BRBS) symptom scales, before surgery, just after surgery and 6 and 12 months later. The Kruskal–Wallis test with the Bonferroni correction was used to compare scores. A mixed model analysis of variance for repeated measurements was then applied to assess the longitudinal effect of surgical modalities on QoL. Results: Before surgery, GHS (P = 0.7807) and BRAS (P = 0.7688) QoL scores…
Hemithyroidectomy versus total thyroidectomy in the intermediate-risk differentiated thyroid cancer: the Italian Societies of Endocrine Surgeons and …
2021
The surgical treatment of the intermediate-risk DTC (1–4 cm) remains still controversial. We analyzed the current practice in Italy regarding the surgical management of intermediate-risk unilateral DTC to evaluate risk factors for recurrence and to identify a group of patients to whom propose a total thyroidectomy (TT) vs. hemithyroidectomy (HT). Among 1896 patients operated for thyroid cancer between January 2017 and December 2019, we evaluated 564 (29.7%) patients with unilateral intermediate-risk DTC (1–4 cm) without contralateral nodular lesions on the preoperative exams, chronic autoimmune thyroiditis, familiarity or radiance exposure. Data were collected retrospectively from the clini…
Sentinel lymph node BIOPSY after neoadjuvant therapy in breast cancer patients with lymph node involvement at diagnosis. Could wire localization of c…
2021
Abstract Introduction Sentinel lymph node biopsy (SLNB) after neoadjuvant therapy (NAT) in node-positive (N+) breast cancer patients at diagnosis remains a controversial issue, with no consensus on implementation or safety. Objectives We sought to assess the accuracy of SLNB after NAT in biopsy-proven N+ cases at diagnosis and the efficacy and accuracy of wire localization of the clipped node to improve results. Material and methods A cross-sectional diagnostic technique validation study in N+ patients following NAT was performed. The biopsy-proven affected lymph node was clipped at diagnosis. SLNB and axillary lymph node dissection (ALND) were performed in cases of clinical-radiological ly…
