Abstract

The aim of the study was to assess if the cost of robotic-assisted total laparoscopic hysterectomy is similar to the cost of standard laparoscopic hysterectomy when performed by surgeons past their initial learning curve. A retrospective chart review of all hysterectomies was performed for benign indications without concomitant major procedures at Orange Coast Memorial Medical Center (OCMMC) and Saddleback Memorial Medical Center between January 1, 2013 and September 30, 2013. Robotic-assisted total laparoscopic hysterectomies (RTLH) and standard laparoscopic hysterectomies (LAVH and TLH) were compared. Data analyzed included only those hysterectomies performed by surgeons past their initial learning curve (minimum of 30 previous robotic cases). The primary outcome was the direct total cost of patient’s hospitalization related to hysterectomy. The secondary outcomes were estimated blood loss, surgery time, and days in hospital post-surgery. A multiple linear regression model was applied to evaluate the difference between RTLH and LAVH/TLH in hospital cost, blood loss, and surgery time, while adjusting for hospital, patient’s age, body mass index (BMI), whether or not the patient had previous abdominal/pelvic surgery, and uterine weight. The χ 2 test was applied to examine the association between hospital stay and surgery type. There were 93 hysterectomies (5 LAVH, 88 RTLH) performed at OCMMC and 90 hysterectomies (6 LAVH, 17 TLH, 67 RTLH) performed at Saddleback Memorial Medical Center. The hospitalization total cost result showed that, after adjusting for hospital, age, BMI, previous abdominal/pelvic surgery, and uterine weight, RTLH was not significantly more expensive than LAVH/TLH (mean diff. = $283.1, 95 % CI = [−569.6, 1135.9]; p = 0.51) at the 2 study hospitals. However, the cost at OCMMC was significantly higher than Saddleback Memorial Medical Center (mean diff. = $2008.7, 95 % CI = [1380.6, 2636.7]; p < 0.0001); and the cost increased significantly with uterine weight (β = 3.8, 95 % CI = [2.3, 5.3]; p < 0.0001). Further analysis showed significantly less blood loss (mean diff. = −78.5 ml, 95 % CI = [−116.8, −40.3]; p < 0.0001) and shorter surgery time (mean diff. = −21.9 min., 95 % CI = [−39.6, −4.2]; p = 0.016) for RTLH versus LAVH/TLH. There was no significant association between hospital stay and surgery type (p = 0.43). After adjusting for patient-level covariates, there was no statistically significant cost difference of performing robotically assisted laparoscopic hysterectomy versus standard laparoscopic hysterectomy when performed by surgeons past their initial learning curve at two community hospitals.

S3-Leitlinie „Diagnostik und Therapie des Karpaltunnelsyndroms“

CME: 2 Punkte

Prof. Dr. med. Gregor Antoniadis Das Karpaltunnelsyndrom ist die häufigste Kompressionsneuropathie peripherer Nerven. Obwohl die Anamnese mit dem nächtlichen Einschlafen der Hand (Brachialgia parästhetica nocturna) sehr typisch ist, ist eine klinisch-neurologische Untersuchung und Elektroneurografie in manchen Fällen auch eine Neurosonografie erforderlich. Im Anfangsstadium sind konservative Maßnahmen (Handgelenksschiene, Ergotherapie) empfehlenswert. Bei nicht Ansprechen der konservativen Therapie oder Auftreten von neurologischen Ausfällen ist eine Dekompression des N. medianus am Karpaltunnel indiziert.

S2e-Leitlinie „Distale Radiusfraktur“

CME: 2 Punkte

Dr. med. Benjamin Meyknecht, PD Dr. med. Oliver Pieske Das Webinar S2e-Leitlinie „Distale Radiusfraktur“ beschäftigt sich mit Fragen und Antworten zu Diagnostik und Klassifikation sowie Möglichkeiten des Ausschlusses von Zusatzverletzungen. Die Referenten erläutern, welche Frakturen konservativ behandelt werden können und wie. Das Webinar beantwortet die Frage nach aktuellen operativen Therapiekonzepten: Welcher Zugang, welches Osteosynthesematerial? Auf was muss bei der Nachbehandlung der distalen Radiusfraktur geachtet werden?
