The Effect of Shigyakusan Used for IBS and MUPS Diagnosed by Abdominal N Line Tenderness
Abstract

 Background & Aims:

 Abdominal N line tenderness for diagnosis and shigyakusan for treatment of irritable bowel
 syndrome ( IBS ) and medically unexplained physical symptoms ( MUPS ) were studied.

 K1 is point of one quarters of distance from center of navel to right anterior superior iliac
 spine. K2 is one quarters of distance from center of navel to upside of the symphysis pubis.
 K3 is center of line from xiphoid process to navel. There are three relevant lines; K1-K3
 line, K2-K3 line, and line of identical length to K1-K3 line originating from K2 and running
 parallel to K1-K3 line. Author collectively named these 'N line'. There was not the study
 under author's investigation that effects of shigyakusan and other medicines were compared.
 Author confirmed existence of mild IBS, for whose patients existing largely, various
 expensive examinations are spent.

 Method:

 The author put pressure on N line by deep palpitation and judged of abdominal N line
 tenderness positive or negative.

 Shigyakusan, a Kampo medicine, was administered to each of N line positive patients, of IBS
 by Rome III, of no IBS by Rome III, and of MUPS. The change of symptoms of IBS and MUPS by
 shigyakusan was showed with an arrow by self-declaration.

 Conclusions:

 Shigyakusan was more effective for IBS than previous medicines. IBS was diagnosed by Rome III
 and N line tenderness and author confirmed the existence of mild IBS which was diagnosed by N
 line tenderness with help of RomeIII. MUPS showed N line tenderness though patients
 complained of no abdominal symptoms. Shigyakusan was very effective for IBS, mild IBS and
 MUPS.
Background & Aims

 The common cause of both IBS and MUPS is generally considered to be mental stress.

 The late prof. Masaharu Katsumi at the Wakayama Medical University found two tender points
 "K1" and "K2" for IBS forty seven years ago. The author found another tender point "K3''. K1
 is one quarters of the distance from the center of the navel to the right anterior superior
 iliac spine. K2 is one quarters of the distance from the center of the navel to the upside of
 the symphysis pubis. K3 is the center of the line from the xiphoid process to the navel.
 There are three relevant lines; the K1-K3 line, the K2-K3 line, and the line of identical
 length to the K1-K3 line originating from K2 and running parallel to the K1-K3 line. The
 author named these lines "N line" collectively.

 The author considers as follows. K1 is the concentration point of nerves coming from the
 right colon, while K2 is the concentration point of nerves coming from the left colon, i.e.
 inferior mesenteric plexus. K3 corresponds to the superior mesenteric ganglion. The K1-K3
 line corresponds to the root of mesentery. The K2-K3 line corresponds to the abdominal aortic
 plexus. The line originating from K2 and running parallel to the K1-K3 line is the line that
 transverses a number of nerves originating from jejunum or ileum, entering side by side into
 the root of mesentery and running to the superior mesenteric ganglion.

 IBS is now diagnosed by the diagnostic criteria formed by symptoms. However, the author
 considers that medical sign of N line tenderness makes reliable diagnosis.

 There was not the study under author's investigation that effects of shigyakusan and other
 medicines were compared. The author confirmed the existence of mild IBS which was diagnosed
 by N line tenderness with the help of Rome III, for whose patients existing largely, various
 expensive examinations and many hours are spent. MUPS showed N line tenderness though the
 patients complain of no abdominal symptoms.

 Method

 The author put pressure on the N line slowly by deep palpitation to check for tenderness of
 the region, comparing N line to the tenderness of the other parts of abdomen. He judged of
 abdominal N line tenderness positive or negative.

 Shigyakusan, a Kampo medicine, was administered to each of N line positive patients, of IBS
 diagnosed by Rome III, of no IBS by Rome III, and of MUPS who have not abdominal symptoms of
 IBS in this study. The author enrolled 110 out-patients who were treated by shigyakusan at
 the Corporate Nakatani Clinic for two years from March 2013 to February 2015.

 The author thinks that double blind study is the best way that shigyakusan is prescribed to
 placebo for clear endpoint discovered though it is very difficult to the psychiatric disorder
 as IBS. However, this time the author assessed the self-declaration of the symptom's change.
 The change of the symptom was showed with an arrow by self-declaration. An entry format was
 adopted by showing Table 1 to the patients. For example, ③→① shows the change of symptoms
 from ③ Significantly bad to ① Almost no symptoms in Table 1. The author used shigyakusan
 regardless of diarrhea or constipation.

 Study of shigyakusan used for IBS:

 The author tried to compare previous drugs to shigyakusan. 7.5g per day of Tsumura's
 shigyakusan ( Tsumura & Co ) was administered to each of 30 cases of IBS to whom Trimebutine
 maleate, Polycarbophil calcium and Oxapium iodide had been described, and was administered to
 each of 18 cases of new patients of IBS and 21 cases of existing patients first treated as
 IBS.(Table2) These patients were diagnosed as IBS by Rome III and abdominal N line
 tenderness, undermentioned in 'Regarding abdominal tenderness of N line' (Table 6).

 Study of shigyakusan used for mild IBS

 The patients of no IBS by Rome III and of abdominal N line tenderness positive were diagnosed
 as mild IBS for the reason in 'Regarding abdominal tenderness of N line' undermentioned
 (Table 6).

 Shigyakusan was used for each of the patients with IBS who have mild to severe
 gastrointestinal symptoms without or with only few other bodily complaints or
 psychobehavioral features[26] :

 7.5g per day of Tsumura' shigyakusan was administered to each of 14 cases of mild IBS(Table
 3).

 Study of shigyakusan used for MUPS:

 MUPS are patients' unexplained & uncertain physical symptoms which are difficult for doctors
 to find the medical causes though MUPS do not imply that physical causes do not exist.
 However, MUPS in this study are physical symptoms other than IBS. When shigyakusan was
 effective for a patient suffered from both physical symptoms of MUPS and abdominal symptoms
 of IBS, the author adopted IBS.

 7.5g per day of Tsumura' shigyakusan was administered to each of 27 MUPS patients who had
 doubt of psychiatric morbidity, for whom the author found no medical scientific
 cause(Table4).

 Concerning N line when the cause of symptoms was clear

 The possibility that the patients are diagnosed as MUPS becomes high if the patients have
 physical symptoms and show abdominal N line tenderness. When the cause of symptoms was clear
 without unaccountable or unexplained symptoms by having been examining, the author put
 pressure on N line by deep palpitation, and the author enumerated the thirty patients'
 conditions or diseases causing symptoms ( Table5 ).
