Canal Syndrome

Perioperative Guyon’s canal and carpal canal pressure in one-forearm portal endoscopic carpal tunnel release surgery were measured in resting position and during active power gripping in 66 hands. This was done using the continuous infusion technique with a local anaesthetic and without pneumatic tourniquet. Immediate mean postoperative Guyon’s canal and carpal canal pressure decreased in both measurements. During active power gripping, postoperative Guyon’s canal pressure was less than 40 mmHg in 61 hands, however, this increased to over 40 mmHg in five hands. In these five hands, Guyon’s canal syndrome did not develop. Guyon’s canal and carpal canal pressures were only correlated during postoperative active power gripping. It remains unclear whether immediate postoperative Guyon’s canal pressure correlates with higher pressures a few days later as reported in cases of transient postoperative Guyon’s canal syndrome.

Ulnar Tunnel

We measured pressure changes in Guyon's canal and the carpal tunnel before and after endoscopic (11 cases) and open (10) carpal tunnel release. We found that release of the flexor retinaculum by endoscopic and open techniques measurably decreased pressure in both the carpal tunnel and Guyon's canal. This study provides an explanation for relief of ulnar tunnel syndrome symptoms following carpal tunnel release and may indicate that carpal tunnel release alone may be sufficient to provide symptomatic relief for most patients with carpal and ulnar tunnel syndromes.

Endoskopische Karpaltunnelspaltung

Im Spital Thusis wurden zwischen 1994 und 2000 122 Patienten wegen eines Karpaltunnelsyndroms operiert. Wir wollten wissen, ob die endoskopische Karpaltunnelspaltung in einem Regionalspital mit genügend hoher Sicherheit angewandt wurde und ob die Ergebnisse mit der offenen Karpaltunnelspaltung vergleichbar sind. In einer retrospektiven Studie konnten wir 82 Patienten mittels Fragebogen über das Operationsergebnis befragen. 39 Patienten wurden offen operiert, 26 mittels der Zweipfortentechnik nach Chow und 17 mittels Einpfortentechnik nach Agee. Schwere irreversible Komplikationen wurden nicht beobachtet. Bezüglich der Operationsergebnisse zeigten sich keine signifikanten Unterschiede in den drei Gruppen. Von den 39 offenen Karpaltunnelspaltungen klagten neun Patienten über Restbeschwerden, wobei es zu einer Reoperation wegen einer Thenarastverletzung kam. Bei den 26 endoskopischen Karpaltunnelspaltungen in Zweipfortentechnik traten bei acht Patienten Restbeschwerden auf, wobei eine Reoperation wegen exzessiver Vernarbung durchgeführt werden musste. Bei den 17 Operationen nach Agee hatten fünf Patienten Restbeschwerden, es musste jedoch keiner reoperiert werden. Die Studie zeigt, dass mit den drei unterschiedlichen Operationsverfahren bezüglich Sicherheit und Therapieerfolg vergleichbare Resultate erreicht wurden. Vorteile wegen dem atraumatischeren Zugang der endoskopischen Techniken konnten wir jedoch nicht objektivieren.

Background This study sought to investigate complication rates/perioperative metrics after endoscopic carpal tunnel release (eCTR) via wide-awake, local anesthesia, no tourniquet (WALANT) versus sedation or local anesthesia with a tourniquet. Methods Patients aged 18 years or older who underwent an eCTR between April 28, 2018, and December 31, 2019, by 1 of 2 fellowship-trained surgeons at our single institution were retrospectively reviewed. Patients were divided into 3 groups: monitored anesthesia care with tourniquet (MT), local anesthesia with tourniquet (LT), and WALANT. Results Inclusion criteria were met by 156 cases; 53 (34%) were performed under MT, 25 (16%) under LT, and 78 (50%) under WALANT. The MT group (46.1 ± 9.7) was statistically younger compared with LT (56.3 ± 14.1, P = .007) and WALANT groups (53.5 ± 15.8, P = .008), F(2, 153) = 6.465, P = .002. Wide-awake, local anesthesia, no tourniquet had decreased procedural times (10 minutes, SD: 2) compared with MT (11 minutes, SD: 2) and LT (11 minutes, SD: 2), F(2, 153) = 5.732, P = .004). Trends favored WALANT over MT and LT for average operating room time (20 minutes, SD: 3 vs 32 minutes, SD: 6 vs 23 minutes, SD: 3, respectively, F(2, 153) = 101.1, P < .001), postanesthesia care unit time (12 minutes, SD: 7 vs 1:12 minutes, SD: 26 vs 20 minutes, SD: 22, respectively, F(2, 153) =171.1, P < .001), and door-to-door time (1:37 minutes, SD: 21 vs 2:51 minutes, SD: 40 vs 1:46 minutes, SD: 33, respectively, F(2, 153) = 109.3, P < .001). There were no differences in complication rates. Conclusions Our data suggest favorable trends for patients undergoing eCTR via WALANT versus MT versus LT.
