我が教室に於ける末梢神経手術の統計的観察

A Statistical Observation on the Peripheral Nerve Operation in IMANAGA Surgical Clinic.

I．緒言

　末梢神経手術に関しては，1776年Cruikschankが犬の迷走神経切断縫合に成功して以来幾多の学者によつて研究されて来たが，臨床的方面に信憑するに足る研究の現われたのは第一次世界大戦の末期からである。而して第二次世界大戦中アメリカを始め各国に於て戦傷者に対する神経手術が盛んに行われた。我が国に於ても，大正14年細見氏により報告されて以来幾多の学者の研究報告が見られる。

　我が教室に於ても，故桐原教授並に今永教授を始め諸先輩及び私共によつて為されて来た神経手術例も多数経験せられたので，ここに戦災により記録消失をまぬがれたもの49例について統計的観察を行い報告する次第である。

Total fourtynine cases of the peripheral nerve operations in our clinic were analyzed statistically and summarized as folows:Loca-lizaton; radial never seventeen cases, ulnar nerve seven cases, median nerve eleven cases, plexus brachialis three cases, nervus peroneus six cases and sciatic nerve three cases. Etio-logy ; fracture thirteen cases, trauma twenty-five cases, injection five cases, tumor one case and miscellaneous five cases. Operative methods ; neurolysis twenty-six, nerve suture seven, transplantation of autograft and brid-ging of a half thickness of separated nerve graft five, transplantation of homograft six, transplantation of hetero-graft one and tubuli-sation six cases. Follow-up results ; comp-letely recovered four, improved ten and unch-anged six cases. Among four cases of comp-lete recovery two were neurolysis and the other two were tubulisation. Ten cases of improve consisted of six neurolysis, two bridging of a half thickness of separated nerve, one transp-lantation of a preserved homagraft and one heterograft transplantation. Follow-up result was good when operated on within six months from the begining of paralysis.
