  • Laparoscopic Transhiatal Surgery for Multiple Epiphrenic Esophageal Diverticula

    Sasaki Tomohiko, Motoyama Satoru, Yasui Ouki, Kato Yujiro, Takahashi Teiji

    The Japanese Journal of Gastroenterological Surgery ( The Japanese Society of Gastroenterological Surgery )  51 ( 9 ) 543 - 550   2018

    <p>A 53-year-old man was referred for detailed examinations on dysphagia. A gastrographin contrast medium study and an esophagoscopy revealed both a 6 cm right epiphrenic diverticulum and a 3 cm left epiphrenic diverticulum in the esophagus. Manometry examination showed a synchronous abnormal contraction and absence of a primary peristaltic wave. Furthermore, lower esophageal sphincter (LES) pressure was high. We diagnosed multiple epiphrenic esophageal diverticula with an esophageal motility disorder. We performed laparoscopic transhiatal diverticulectomy and Dor's fundoplication following Heller myotomy. The postoperative course was uneventful, and his symptoms improved. Simultaneous bilateral epiphrenic esophageal diverticula are rare diseases. Laparoscopic transhiatal surgery can be a useful treatment for this disease.</p>

    A 74-year-old man underwent distal gastrectomy, D1 + with No.14v lymph node dissection, and Roux-en Y reconstruction for advanced gastric cancer with infiltration into the transverse mesocolon. When about 2 weeks had elapsed after initiation of adjuvant chemotherapy, he developed abdominal distention. Ascites was confirmed by a CT scan undertaken 3 months after the surgery. Abdominal paracentesis yielded a milky white ascites with remarkably elevated triglyceride level. Chylous ascites was thus diagnosed. Since conservative therapy was unsuccessful, he was referred to our hospital for further treatments 7 months after the surgery. Plain abdominal CT scan performed immediately after lymphangiography revealed leakage of lipiodol around the celiac artery and/or common hepatic artery. Upon laparotomy, we ligated and sutured the chylorrhea site to close the chylorrhea by using an absorbable tissue-reinforcing material and a physiological tissue adhesive.<BR>Prolonged chylorrhea for a long time extremely worsens the general condition of the patient. When we encounter refractory chylous ascites, it is important to perform surgical therapy without hesitation that can lead to a curative therapy.

  • Prevention of Evaporation Caused by a Rapid Immunohistochemistry Method Applying Non-contact Alternating-Current Electric-Field Mixing

    <p>It is widely recognized that pathology is the most important factor for staging and selecting effective chemotherapy for patients with cancer. Immunohistochemistry (IHC) is a reliable screening method, but intra-operative diagnosis by frozen section with IHC is not possible because IHC takes approximately 6 hours. We recently developed a rapid-IHC method that makes use of an alternating current (AC) electric field to facilitate the antigen-antibody reaction, and reported its usefulness for detection of lung cancer and breast cancer. The antibody is mixed within microdroplets as the voltage is switched on and off at specific intervals. The resultant Coulomb force stirs the diluted solution on the sections, which increases the opportunity for contact. The rapid-IHC device reduces the time required for IHC as well as the amount of antibody required for analyses. The device may also be applied for in situ hybridization (ISH); however, ISH requires a warm temperature, such as 37℃, and a longer processing time than the rapid-IHC method. Consequently, evaporation can be a problem during ISH. The aim of the present study was to evaluate the utility and reliability of an oil cover and cover cap made of polyethylene terephthalate (PET) for preventing evaporation due to the AC electric field applied to facilitate the antigen-antibody reaction. We have shown that both the oil cover and PET cover cap prevented evaporation when using the rapid-IHC device.</p>
