Chirurgie AND Surgery AND Technique

Adenocarcinoma of the esophagogastric junction (AEG) still represent a certain surgical challenge. In contrary to the trend of thoracoabdominal surgery for AEG I and AEG II cancer, the proximal gastrectomy is regaining popularity through new reconstruction methods such as the double tract reconstruction. Proximal gastrectomy followed by double tract reconstruction represents an alternative for the thoracoabdominal approach for suitable AEG II cancer and an alternative to the total gastrectomy for AEG III cancers...

Robotic microsurgery is an emerging field in reconstructive surgery, which provides benefits such as improved precision, optimal ergonomics, and reduced tremors. However, only a few robotic platforms are available for performing microsurgical procedures, and successful nerve coaptation is still a challenge. Targeted muscle reinnervation (TMR) is an innovative reconstructive procedure that rewires multiple nerves to remnant stump muscles, thereby reducing neuroma and phantom limb pain and improving the control of bionic prostheses...

Rhizarthrosis is one of the most common arthritic changes in the hand, which has led to the development of a large number of surgical methods in recent years. In addition to the traditional resection arthroplasty with tendon suspension or interposition, if needed, thumb saddle joint prostheses are being used more and more frequently. However, these are not an option for all patients such as those with severe osteoporosis, severe nickel allergy, insufficient height of the trapezium or STT osteoarthritis. This study examined whether the traditional surgical methods continue to have their "right to exist" or whether they will be replaced by prostheses...

Selective neurectomy refers to the targeted transection of motor nerve fibres at their entry into the muscle in order to reduce the increased muscle tone in cases of spastic paralysis. This procedure has regained popularity in recent years, especially in the upper extremity. First and foremost, it requires an exact knowledge of the topographical anatomy of muscle innervation. To be able to control the extent and localisation of the denervation, the terminal nerve branches must be visualized precisely during the procedure...

Today, endoscopy plays a decisive role not only in the detection of colorectal adenomas and carcinomas, but also in the treatment of precancerous lesions, in particular flat adenomas and early carcinomas. In recent years, endoscopic submucosal dissection (ESD) has become increasingly important alongside classic polypectomy and mucosal resection after saline injection using a snare (EMR). Using ESD the lesion is marked, injected submucosally using viscous substances and the mucosa incised and tunneled with a transparent cap and a fine diathermy knife...

The review titled "Staging and Diagnostics of Rectal Cancer" aims to provide insight to imaging techniques in patients with rectal cancer.Rectal cancer is among the most common malignancies, with one of the highest mortality rates worldwide. Timely diagnosis and therapy of this cancer therefore has important socio-economic implications.Radiological imaging plays a major role in the planning of subsequent therapy. Modern tomographic imaging is used not only for initial diagnosis, but also for staging.The individual role of different imaging techniques in diagnosis of rectal cancer will be explained in detail, and their function in general...

PURPOSE: Nearly all patients with hip fractures undergo surgical treatment. The use of different anesthesia techniques during surgery may influence the clinical outcomes. The optimal anesthetic technique for patients undergoing hip fracture surgery is still controversial. We performed this updated systematic review and meta-analysis to compare clinical outcomes of patients undergoing hip fracture surgery with different anesthesia techniques. SOURCE: Articles published from 2000 to May 2023 were included from MEDLINE, Embase, Web of Science, and the Cochrane Library...

The aim of this paper was to describe the technique of laparoscopic gastrectomy for gastric carcinoma and to present a review of current international studies on this topic.The first part describes and documents a standard laparoscopic gastrectomy for carcinoma. In the second part, after an EMBASE and PubMed search, a total of 123 quality-relevant randomised (RCT) and non-randomised (non-RCT) studies on laparoscopic gastrectomy are identified from a primary total of 3,042 hits by systematic narrowing. The study results are then summarised conclusively for the target criteria of feasibility, outcome, oncological quality, morbidity and mortality...

Nowadays, it is only relatively rare and in selected situations that colonic interposition is chosen rather than the stomach as a reconstructive organ for replacing the oesophagus. The colon is a reliable organ for tubular replacement of the oesophagus when the stomach is not available for reconstruction. Colon interposition is a complex and complicated operation. It requires a specific indication and thorough preoperative preparation. From a technical point of view, colon interposition places high demands on the selection and surgical dissection of the vascular supply to the reconstructed organ...

BACKGROUND: The upper extremity and particularly the hands are crucial for patients in interacting with their environment, therefore amputations or severe damage with loss of hand function significantly impact their quality of life. In cases where biological reconstruction is not feasible or does not lead to sufficient success, bionic reconstruction plays a key role in patient care. Classical myoelectric prostheses are controlled using two signals derived from surface electrodes in the area of the stump muscles...

BACKGROUND: Robotic-assisted harvest of the deep inferior epigastric perforator (DIEP) flap is an innovative modification of the traditional open preparation for autologous breast reconstruction. It is assumed that donor-site morbidity (herniae, bulging) is reduced by minimising the fascial incision length in robotic-assisted DIEP flap harvest. MATERIAL & METHODS: This is the first report of a robotic-assisted DIEP harvest in Germany, which was performed in April 2023 at the University Hospital of Freiburg in an interdisciplinary approach of the Departments of Plastic Surgery, Urology and Gynaecology...

Complex brachial plexus injuries with multiple or complete root avulsions make intraplexic reconstruction impossible in some cases. Such cases necessitate the use of extraplexic nerve donors such as the spinal accessory nerve or intercostal nerves. The contralateral C7 root represents a donor with a high axon count and can be used as an axon source in such cases. We summarise current indications, surgical technique and functional results after a contralateral C7 transfer in cases of brachial plexus injury, describing some of our own cases and including a selective literature review...

The gold-standard for bone, ligament and joint surgery in the wrist is locoregional anesthesia in most countries. Wide-Awake Local Anesthesia No Tourniquet (WALANT) is commonly used for simple soft-tissue hand surgery procedures such as carpal tunnel or trigger finger release, and can now also be safely used in procedures such as proximal row carpectomy, scapholunate ligament repair or partial wrist fusion, to name but a few. This article describes the use of WALANT for complex surgery in the wrist. WALANT surgery offers many known benefits, such as enhanced patient safety and comfort, simplified perioperative process and avoidance of anesthesia-related risks, and also allows the surgeon to perform intraoperative testing of the repaired structures...

Carinal resections are consistently described in the literature as one of the most challenging procedures in thoracic surgery. Depending on the underlying disease and its extent, different resection forms and reconstruction techniques are required. From a surgical point of view, the complex anatomy, and the technique of reconstruction of the central airway are particularly challenging. However, complex airway management and extensive postoperative follow-up demonstrate that these procedures require a multidisciplinary team effort beyond surgical expertise...

BACKGROUND: Several surgical techniques have been reported for flexor tendon zone 1a-b lacerations without a clear consensus on the gold standard treatment. The purpose of this multicentre study was to measure the outcomes of zone 1a-b flexor tendon injuries treated with a pull-out suture (POS) versus direct suture (DS) technique. PATIENTS AND METHODS: Fifteen patients were treated with the pull-out technique and 22 patients with a direct suture technique between 2014 and 2020...

After more than a decade of good results using the combination of cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) in the treatment of peritoneal carcinosis of colorectal origin, the PRODIGE7 study, which specifically evaluated the role of HIPEC, failed to show any superiority in terms of overall and disease-free survival for the CRS+HIPEC combination compared with CRS alone. This study constituted a radical change in the knowledge and therapeutic attitudes observed to date...

BACKGROUND: Large-diameter head (LDH) total hip arthroplasty (THA) with a monobloc acetabular component improves hip stability. However, obtaining initial press-fit stability is quite challenging in atypical acetabula. The purpose of this study was to assess primary and secondary fixation of monobloc cups in atypical acetabula. METHODS: In this consecutive case series, the local arthroplasty database was used to retrospectively identify patients with secondary osteoarthritis who underwent primary hip replacement with press-fit only LDH monobloc acetabular components between 2005 and 2018 and who had a minimum of 2 years of follow-up...

A desmoid tumour, also known as aggressive fibrous tumour or desmoid fibromatosis, is a rare, benign tumour originating from connective tissue cells. Desmoid tumours account for approximately 0.03+% of all neoplasms and less than 3+% of all soft tissue tumours. The estimated incidence in the general population is 2 to 4 cases per million people per year [1]. Desmoid tumours are characterised by aggressive growth but typically do not metastasize. They often occur in young adults and preferably affect specific body regions such as the abdomen, shoulder, chest, or extremities...

BACKGROUND: The vertebral arteries (VA) play a critical role by supplying nearly one-third of the brain's blood flow, predominantly contributing to the posterior circulation. These arteries may need to be exposed in a various cranial and cervical procedures and offers access to investigate or treat vascular lesions by endovascular means related to the posterior circulation. Given its complex anatomy, which is subject to numerous variations, and its role in supplying vital brain regions, a thorough understanding of the VA's anatomy is paramount for any related procedure...
