Complete REtraction of the StomaCh using Penrose Drain and liver reTractor (CRESCENT) during laparoscopic distal pancreatectomy
Langenbeck's Archives of Surgery, 2020Co-Authors: Seiko Hirono, Keiji Hayata, Manabu Kawai, Ken-ichi Okada, Motoki Miyazawa, Yuji Kitahata, Ryohei Kobayashi, Shinya Hayami, Masaki Ueno, Hiroki YamaueAbstract:Purpose Laparoscopic distal pancreatectomy (LDP) is a well-accepted procedure for benign and malignant diseases of the pancreatic body and/or tail. To perform it safely, a wide operative field is crucial. For the maintenance of a good surgical field during LDP, we developed an original technique for stomach retraction: “Complete REtraction of the StomaCh using Penrose Drain and liver reTractor, CRESCENT.” Methods In CRESCENT technique, the body and antrum of the stomach are suspended by two Penrose Drains, and the fundus and/or upper body of the stomach are retracted upward using a liver retractor. After complete retraction, the stomach is well attached to the abdominal wall and forms a crescent-like shape. Before we developed the CRESCENT technique, we pulled the antrum of the stomach laterally by suture and hanged the body of the stomach upward using a Penrose Drain (control method). We evaluated perioperative outcomes of the 87 consecutive patients who underwent LDP and compared outcomes of CRESCENT technique ( n = 24) and previously used technique as a control ( n = 63). Results Operative time was significantly shorter in the CRESCENT technique than in control method (median, 234 vs. 303 min, P

RESULTS Operative time was significantly shorter in the CRESCENT technique than in control method (median, 234 vs. 303 min, P < 0.001). We found no significant differences in incidences of overall morbidity (16.7 vs. 20.6%, P = 0.677), including grade B/C postoperative pancreatic fistula (8.3 vs. 7.9%, P = 0.455), between CRESCENT technique and control method. There was no mortality by either method. CONCLUSIONS Our original technique, CRESCENT, is a simple procedure in which the stomach is completely retracted during LDP.

Clinical significance of Drainage tube insertion in laparoscopic cholecystectomy: a prospective randomized controlled trial
Journal of Hepato-Biliary-Pancreatic Surgery, 2007Co-Authors: Kazuhisa Uchiyama, Manabu Kawai, Masaji Tani, Hiroshi Terasawa, Takashi Hama, Hiroki YamaueAbstract:Background/Purpose We aimed to investigate the appropriateness of inserting an intraperitoneal Drainage tube after laparoscopic cholecystectomy (LC), based on postoperative pain and clinical courses, in a randomized comparative study. Methods One hundred and twenty patients who were to have LC were enrolled in this prospective randomized study. An 8-mm Penrose Drain was retained below the liver bed for 42 h in each of 60 patients (group A), and no Drain was retained in the remaining 60 patients (group B). Patients in each group were hospitalized for 4 days after operation, and the pain reported by the patients, using a visual analogue pain scale (VAS), and the time courses of changes in the highest body temperature, leukocyte count, and C-reactive protein (CRP) were studied comparatively for men and women. Results Mean VAS scores were significantly greater in group A than in group B at 24 h ( P = 0.00004), and 48 h ( P = 0.0014) after operation. When sex-stratified changes in mean VAS scores were compared within group A, females had more pain than their male counterparts at 24 h ( P = 0.030), but group B showed no sex differences. When the number of patients who used analgesics postoperatively was compared between groups A and B, analgesics were used more frequently in group A. When changes in maximum body temperature were compared, the change was significantly higher in group A than in group B on day 2 after the operation ( P = 0.017). Conclusions Postoperative pain was intensified by the insertion of a Drainage tube after LC. This tendency was stronger in women.

Low-cost high-fidelity ultrasound nerve block phantom gels: Axillary brachial plexus simulator
Pain Practice, 2012Co-Authors: Loreto Lollo, A StogiczaAbstract:Introduction: Peripheral nerve blocks are commonly performed procedures for chronic pain treatment. We describe a low-cost, reproducible, high-fidelity axillary brachial plexus block simulator phantom gel created with readily available materials. Methods: A brachial plexus ultrasound phantom was built using a suction container as its base. The brachial vein was simulated using a Penrose Drain and the brachial artery by a Foley catheter filled with water. Median, ulnar and radial nerves were mimicked by rubber bands glued to the “artery” and the musculocutaneous nerve was attached to a polyethylene sheet reproduced the fascial layer between muscles and the the plexus sheath. The container was filled with gel, consisting of gelatin and cellulose fiber (Bude). After cooling the model was removed from its container for use. Results: The visual opacity of the gel prevented operators from localizing the brachial plexus by inspection alone. The plastic films representing fascia and plexus sheath were visualized under ultrasound and mimicked the resistance of real fascia, when punctured with a needle. The brachial vein and artery were distinguished on the basis of their differing lumens and wall thickness. The rubber bands demonstrated a brighter echogenic effect similar to nerves. Repeated use resulted in minimal gel disruption with air bubbles. Conclusions: Low cost, high fidelity nerve block simulator phantoms can be easily built using commonly available materials. This allows greater training opportunities in ultrasound guided nerve blocks and improves operator proficiency. This technique can be easily adapted to create other nerve block phantoms.

Low-cost high-fidelity ultrasound nerve block phantom gel: Femoral nerve simulator
Pain Practice, 2012Co-Authors: Loreto Lollo, A StogiczaAbstract:Introduction: Peripheral nerve blocks are commonly performed procedures for chronic pain treatment. We describe a low-cost, reproducible, high-fidelity femoral nerve block simulator phantom gel created with readily available materials. Methods: A femoral nerve ultrasound phantom was built using a polypropylene basin as its base. The femoral vein was simulated using a Penrose Drain and the femoral artery by a Foley catheter filled with water. The femoral nerve was created using a Penrose Drain filled with rubber bands. These structures were laid in the base according to their correct anatomic location. The container was filled with gel, consisting of gelatin and cellulose fiber (Bude). The fascia lata and iliaca were simulated by sheets of polyethylene films. After cooling the model was removed from its container for use. Results: The visual opacity of the gel prevented operators from localizing the femoral nerve by inspection alone. The plastic films representing fascia were visualized under ultrasound and mimicked the resistance of real fascia, when punctured with a needle. The femoral vein and artery were distinguished on the basis of their differing lumens and wall thickness. The rubber bands demonstrated a stippling echogenic effect similar to nerve bundles. Repeated use resulted in minimal gel disruption with air bubbles. Conclusions: Low cost, high fidelity nerve block simulator phantoms can be easily built using commonly available materials. This allows greater training opportunities in ultrasound guided nerve blocks and improves operator proficiency. This technique can be easily adapted to create other nerve block phantoms.
