Trapeziometacarpal osteoarthritis – a stepwise therapeutic approach

Review article: Biomedical intelligence
Nuessle NC, Vögelin E, Hirsiger S
Swiss Med Wkly. 2021;151:w20465

Osteoarthritis of the trapeziometarcarpal joint, also called rhizarthrosis, is a common finding in the second half of life. It has a higher prevalence in females and is of growing importance in ageing societies. A variety of conservative and surgical treatment options are known, including conservative treatment up to joint replacement. Without treatment, rhizarthrosis can lead to disabling pain and loss of hand function. The goal of this overview of treatment options is to present a stepwise approach that can be initiated by any physician.

Abdominal wall reconstruction using biosynthetic absorbable mesh in high-risk complex ventral hernia

Biosynthetic mesh may represent an improvement on biological and large pore synthetic meshes for high-risk complex ventral hernia repair.  This study reports a large series of abdominal wall reconstructions using biosynthetic mesh in complex ventral hernia. The findings indicate promising early outcome data associated with use of biosynthetic mesh. 

Outcome of open inguinal hernia repair using sutureless self-gripping mesh – a retrospective single cohort study

This study shows that open inguinal hernia repair using a self-gripping mesh is feasible, with a short operation time and low hernia recurrence rates in a peripheral teaching hospital. However, significant differences in neurological disturbances dependent on the surgeons experience were identified. Especially younger patients should be operated on by an experienced surgeon to reduce neurological disturbances and neuralgia.

Enhanced-view totally extraperitoneal approach in emergency ventral incision hernia repair: a case report

Swiss Med Wkly. 2021;151:w20423

The rate of emergency operations for incarcerated and strangulated ventral hernias is about 10–15%, with worse outcomes than elective surgery. A recent laparoscopic technique called the enhanced-view totally extraperitoneal approach (eTEP) was shown to be indicated in elective repair of ventral and incisional hernias, and has a lower rate of postoperative morbidity than the Rives-Stoppa technique, while having the same indications. However, use of the eTEP laparoscopic technique in emergency ventral hernia repair has not yet been reported.

Multimodal treatment strategies for colorectal liver metastases

Review article: Biomedical intelligence

The optimal treatment of patients with colorectal liver metastases requires the timely association of various strategies, and all cases must be discussed at multidisciplinary team conferences. While colorectal liver metastases was a uniformly lethal condition a few decades ago, it has become amenable to curative therapies, with excellent quality of life in many scenarios. This review reports on up-to-date treatment modalities and their combinations in the treatment algorithm of colorectal liver metastases.

Lymphovascular invasion is an independent prognostic factor for survival in pathologically proven N2 non-small cell lung cancer

Lymphovascular invasion was identified as the only independent prognostic factor for 5-year overall survival and recurrence-free survival in this pathologically proven N2 NSCLC cohort when controlled for adjuvant therapy. This study extends the current evidence of an adverse prognostic effect of lymphovascular invasion on a stage III population, confirms the adverse prognostic effect of lymphovascular invasion detected by immunohistochemistry, and thereby reveals another subgroup within the pN2 population with worse prognosis regarding 5-year overall survival and recurrence-free survival.

Laparoscopic liver resection: a single-centre experience

Original article

In the last two decades laparoscopic liver resection has developed dramatically. This study aimed to describe the experience and the results of laparoscopic liver resection at a single centre over 12 years.

Active clearance of chest tubes after cardiac surgery: a propensity score matched analysis

Swiss Med Wkly. 2020;150:w20394

Chest tubes inserted to drain shed mediastinal blood after cardiac surgery often become clogged, limiting their capacity to evacuate blood, and leading to blood retention and retained blood syndrome. The aim of this study was the assessment of the efficacy of an active tube clearance system in the reduction of retained blood syndrome after cardiac surgery.

Postoperative outcome of tracheal resection in benign and malignant tracheal stenosis

Original article

Swiss Med Wkly. 2020;150:w20383

Tracheal or cricotracheal resection is the standard of care for definitive treatment of tracheal stenosis. However, the incidence is low, the management is complex, and only a few centres have reported their experience.

A retrospective epidemiological study of paediatric femoral fractures

Original article

Swiss Med Wkly. 2020;150:w20360

Femoral fracture is a significant major trauma in children and adolescents, sometimes resulting in serious complications. This study aimed to determine the epidemiology of femoral fractures and to define associated injuries and mortality incidence in a pediatric population below 16 years old.
