The primary goal of treatment of an injury to the fingertip is a painless fingertip with durable and sensate skin. Knowledge of fingertip anatomy and the available techniques of treatment is essential. For injuries with soft-tissue loss and no exposed bone, healing by secondary intention or skin grafting is the method of choice. When bone is exposed and sufficient nail matrix remains to provide a stable and adherent nail plate, coverage with a local advancement flap should be considered. If the angle of amputation does not permit local flap coverage, a regional flap (cross-finger or thenar) may be indicated. If the amputation is more proximal or if the patient is not a candidate for a regional flap because of advanced age, osteoarthritis, or other systemic condition, shortening with primary closure is preferred. Composite reattachment of the amputated tip may be successful in young children. The outcome of nail-bed injuries is most dependent on the severity of injury to the germinal matrix.

Purpose: Assessment of tissue perfusion using near-infrared fluorescence (NIR) with indocyanine green (ICG) is gaining popularity, however reliable and objective interpretation remains a challenge. Therefore, this study aimed to establish reference curves for vital tissue perfusion across target tissues using this imaging modality.
Methods: Data from five prospective study cohorts conducted in three Dutch academic medical centres between December 2018 and June 2023 was included.

Introduction: Endoscopic antireflux therapy has shown promising potential in the treatment for gastro-oesophageal reflux disease (GERD). However, there is currently no universally accepted standard for endoscopic surgery. Therefore, we introduced antireflux mucosal valvuloplasty (ARMV), an innovative endoscopic treatment for GERD.

Thinning of anterolateral thigh flap is challenging. Anatomical studies have shown variations in arterial branching patterns in the subcutaneous layer, which were suspected to be the reason for the high frequency of thinning failures. We attempted to visualize subcutaneous arterial courses preoperatively and perform thinning of perforator flaps using this information appropriately.

Robot-assisted surgery represents a significant innovation in reconstructive microsurgery, providing enhanced precision and reduced surgeon fatigue. This study examines the integration of robotic assistance in a series of 85 consecutive robot-assisted microsurgical (RAMS) operations. It aims to evaluate changes in the integration of RAMS during the implementation phase in a single institution.
