Abstract

Central compartment clearance (CCC) for Papillary thyroid cancers (PTC) is one of the factors causing postoperative hypocalcaemia. We aimed to examine determinants of this major sequela. 41 patients treated for PTCs between 2014 and 2016 were studied. Surgical details, tumour and nodal characteristics, incidence of transient, temporary and permanent hypocalcaemia were noted. Central clearance was done bilaterally in 24 (58.5%) cases, ipsilaterally in 17 (41.6%). Central nodes were involved in 26 (63.4%) cases, unilaterally in 15 (36.6%), bilaterally in 11 (26.8%). Transient hypocalcaemia developed in 10 (24.4%) cases, temporary hypocalcaemia in 6 (14.6%) cases, and permanent hypocalcaemia in 2 (4.9%) cases. 17 (41%) patients were symptomatic. 9 (21.9%) patients received intravenous calcium. The only factor consistently associated with development of hypocalcaemia of all patterns, was the presence of matted central compartment nodes (p = 0.021). Matted nodes also related to a longer length of stay (p = 0.04) and requirement of intravenous calcium (p = 0.000). Extent of CCC, nodal yield, nodal positivity, perinodal extension, number of parathyroids identified, gender or pT size were not significantly associated. Symptomatic patients did not necessarily become permanently hypocalcaemic (p = 0.8). Patients requiring intravenous calcium were more likely to take oral calcium after discharge (p = 0.002). Postoperative hypocalcaemia is more likely in cases with bulky involved central nodes where extensive clearance is done. In routine CCC, even if done bilaterally, preservation of parathyroid function is possible. Permanent hypocalcaemia after CCC need not be taken as inevitable.

Neu im Fachgebiet Chirurgie

Antibiotika bei Erwachsenen mit Appendizitis oft ausreichend

Bei etwa zwei Drittel aller Erwachsenen mit akuter Appendizitis könnte eine antibiotische Behandlung ausreichen, wie eine Metaanalyse nahelegt. Die Komplikationsrate war insgesamt gering, auch wenn letztlich doch eine Op. fällig wurde.

Katheterablation bei Vorhofflimmern: Ist frühe Intervention von Vorteil?

Bei Patienten mit Vorhofflimmern scheinen die Therapieergebnisse bezüglich Rezidivfreiheit bei frühzeitiger Katheterablation besser zu sein als bei später erfolgter Ablation. Dafür sprechen Ergebnisse einer aktuellen Registeranalyse. 

Beugt Tranexamsäure schweren Blutungen auch in der Allgemeinchirurgie vor?

Ergebnisse einer Subgruppenanalyse der POISE-3-Studie sprechen dafür, dass eine Prophylaxe mit Tranexamsäure auch bei allgemeinchirurgischen Eingriffen das Risiko für schwere Blutungen senkt.

Höhere Anspannung vor der Op. führt offenbar zu besserem Ergebnis

Ein gewisses Maß an Stress zu Beginn der Op. wirkt sich möglicherweise positiv auf das Gelingen aus, so ein Team aus Boston. Die Komplikationsrate ging unter diesen Umständen signifikant zurück.
