Clinical and Experimental Study of Disorders of the Pancreas 53 CLINICAL AND EXPERIMENTAL STUDY OF DISORDERS OF THE PANCREAS SHINGO AOYAMA 2nd Department of Internal .Medicine, Nagoya University School of Medicine (Director: Prof. Shingo Aoyama) For the past several years various experimental and clinical observations have been made on disorders of the pancreas in this department by the writer and his co-researchers (Motoaki Kishikawa et a!.). The items of content listed below are the selective results of those observations, which the writer presented as a special report before the joint meeting of the 51st General Assembly of the Japanese Society of Internal Medicine and the 41st Assembly of the Gastro-enterological Society of Japan, held in April, 1954. A summary of this report constitutes the body of this paper, arranged in the same order as the original. Due to the limited space most of the data on the indi­ vidual experiments have been omitted, and, as a whole, only their summarized results are recorded herein. CONTENTS I. Some fundamental items 1.

Gastrectomy had been performed for gastric or duodenal ulcer in 35, gastric cancer in 14, gastroptosis in 2, and gastric trauma in 1 of these patients. Reconstruction after gastrectomy was performed by the Billroth II method (B-ll method) in 31 patients, Billroth I method (B-I method) in 17, Roux-en-Y method (Roux-Y method) in 3, and esophagogastrostomy in 1. The period between gas- trectomy and discovery of gallstones was 1-5 years in 9, 5-10 years in 10, and 10 years or longer in 33, or more than 60% of the patients. Gallstones were present in the gallbladder alone in 33 , bile duct alone in 9, gallbladder and bile duct in 10; the percentage of bile duct stones was high . The type of stones was bilirubin-calcium stones in 21, black stones in 12, pure cholesterol stones in 1, combined stones in 4, mixed stones in 12, and others in 2; pigment stones accounted for 63 .5%. Gallstones were symptomatic in 78.8% of the patients, and abdominal pain was the most frequent symptom. Bile was positive on bacterial culture in 68.4%, and Gram-negative bacilli were the most frequently isolated. Lymph node dissection, vagotomy, cholestasis , and biliary tract infection are considered to be related to cholelithiasis after gastrectomy.

Intrathoracic gastric volvulus: an autopsy case report. Autopsy Case Rep [Internet]. 2013;3(2):21-29. http://dx.doi.org/10.4322/acr.2013.014 ABSTRACT First described by Berti in 1866, gastric volvulus (GV) is an uncommon and potentially lethal entity. GV occurs when the stomach twists by more than 180º resulting in obstruction of the alimentary tract, visceral ischemia, necrosis, and perforation. It is classified according to the rotation axis in organoaxial, mesenteroaxial or a combination of both. The clinical presentation can be acute, and is usually severe or chronic, which sometimes may be asymptomatic. It predominantly occurs in the fifth decade of life, but children, mainly those under the age of 1 year, may be affected. No ethnicity or gender was observed to show predominance. This entity is related to gastric, diaphragmatic disorders as well as laxity of gastric ligaments. Acute GV may complicate with incarceration and strangulation of the stomach when gastric necrosis ensues. These cases show a mortality rate of 60%. The authors report the fatal case of a surgically treated GV in a 43-year-old female patient who looked for medical care only after 1 month of initial symptoms. Diagnosis was confirmed with a thoracic and abdominal axial computed tomography. Besides the entire stomach being herniated and twisted into the thoracic cavity, the pancreas was pulled up through the hiatal orifice, provoking acute pancreatitis.

  • Superior Mesenteric Artery Syndrome Coexists with Nutcracker Syndrome in a Female
    Shi et al. BMC Gastroenterology (2019) 19:15 https://doi.org/10.1186/s12876-019-0932-1 CASE REPORT Open Access Superior mesenteric artery syndrome coexists with Nutcracker syndrome in a female: a case report Ying Shi1,2* , Guangya Shi3, Zhenyu Li4, Yanfang Chen1,2, Shaohui Tang1,2 and Wei Huang1,2* Abstract Background: Superior mesenteric artery (SMA) syndrome, also known as Wilkie’s syndrome or Benign duodenal stasis, is a rare benign disease. It could threaten the life if the manifestation is severe and the treatment is inappropriate. In the patients with SMA syndrome, the third portion (transverse part) of the duodenum is compressed externally between the SMA and abdominal aorta (AA) leading to duodenal stasis and gastrointestinal obstruction. SMA syndrome may rarely combine with Nutcracker syndrome when left renal vein (LRV) was compressed between SMA and AA. Case presentation: A 32-year-old female patient presented with complaints of gradually severe bloating, epigastric pain, left flank ache, nausea and occasional vomiting of 1 month’s duration. The epigastric and left flank ache was aggravated when the patient was supine and relieved in a prone or left lateral decubitus. The abdominal bloating was associated with early satiety. The vomiting always started 40 min after meal. The patient gave a history of urine stone with drotaverine hydrochloride tablets treatment for two weeks before the gastrointestinal symptoms arising. The patient had no significant surgical history, but had a rapid weight loss of approximately 10 kg with a body mass index (BMI) from 21 kg/m2 to less than 18 kg/m2 over the last two months.

  • Some Points in the Differential Diagnosis of Chronic Indigestion
    Postgrad Med J: first published as 10.1136/pgmj.11.118.276 on 1 August 1935. Downloaded from 276 POST-GRADUATE MEDICAL JOURNAL August, 1935 SOME POINTS IN THE DIFFERENTIAL DIAGNOSIS OF CHRONIC INDIGESTION. By HERBERT J. PATERSON, C.B.E., M.C., M.D., F.R.C.S. Given the disease it is easy to deduce the symptoms which may accompany that particular disease. In the investigation of an individual case the problem must be approached from a different angle, for then it is the symptoms which are known whereas the disease which is the cause of these symptoms is the unknown quantity. Consequently, at the bedside the clinician has first to obtain an accurate and detailed history and then attempt inductively to ascertain the cause or causes which produce these symptoms. Inasmuch as there may be many possible causes for similar symptoms he has to consider the symptoms in detail together with the information gained by examination of the patient and then make a diagnosis by a process of exclusion. When in this way a provisional diagnosis has been made the signs and symptoms should be compared with those usually associated with the disease suspected, to see whether these confirm the provisional diagnosis. By far the most important symptoms of chronic indigestion are pain and dis- comfort. It is necessary, therefore, to differentiate between these symptoms, for real pain which is recurrent or constant is almost always due to some organicProtected by copyright. lesion. The crucial diagnostic point is the time relation of the discomfort or pain to the ingestion of food.
