Multi-Port Versus Single-port Cholecystectomy

Cholelithiasis

The aim of this study is to compare results of the new surgical strategy to the traditional 4-ports technique for cholecystectomy in a randomized controlled trial (RCT). In particular we are going to investigate the procedures in terms of overall morbidity, while taking into considerations skin-incision's related morbidity, postoperative pain and cosmetic results which are the hypothetical benefits of the new approach. Other parameters are supposed to be unchanged, considering evidences from recent literature. Surgical procedures: 4 ports cholecystectomy (4PC): a 12mmHg pneumoperitoeum is created either by a 10mm umbilical Hasson's port or by a Verress needle followed by a 10mm umbilical port insertion; further one 10mm and two 5mm ports are placed according to the preferred technique. Single Port Access cholecystectomy (SPC): the single-port device is inserted through the umbilicus, by means of an adeguate incision, as the only access to the abdominal cavity. A trans-abdominal suture in right hypochondrium is placed through the gallbladder wall of the fundus to retract it. Primary endpoint: overall morbidity rate (at 60 days from surgery) Secondary endpoints: skin-incision's related morbidity rate (at 60 days from surgery) perioperative pain cosmetic results long-term morbidity (12 months) intraoperative time "conversion SPC to 4PC" rate "conversion to laparotomy" rate hospital stay

Natural Orifice Translumenal Endoscopic Surgery (NOTES) Transvaginal Cholecystectomy

CholelithiasisBiliary Dyskinesia

Natural Orifice Translumenal Endoscopic Surgery (NOTES) describes a new field of investigational surgery which uses the endoscope as the primary operative tool. The insertion sites for the endoscope include natural orifices such as the mouth, anus, vagina, or urethra. Multidisciplinary teams of surgeons and gastroenterologists collaborate to develop safe and effective surgical techniques via the natural orifice route in order to avoid surgical incisions. Early studies have focused on transvaginal surgery as the access route to the abdomen as it sidesteps troubling questions about infection and closure of the organ. This study is a pilot study to test the feasibility to NOTES transvaginal cholecystectomy using conventional surgical and endoscopic tools.

The Construction of Clinical Database and Multiomics Biobank Based on a Multicentral Prospective...

Biliary Tract DiseasesGallbladder Cancer4 more

The aim of the study is to establishing a standardized biobank and a clinical information database for patients with benign and malignant tumors of the biliary system. With follow-up plans and advanced multiomics technology, a multiomics database for patients with benign and malignant tumors of the biliary tract will be further established. Based on the above work, real-world clinical research on the diagnosis and treatment of biliary tract tumors is about to be carried out, and a high-standard cohort research foundation is laid for precision therapy based on multiomics characteristics and molecular typing of biliary tract tumors.

Evaluation of MRI Sequences for Ultra-rapid Acquisition of Bile Ducts Images

GallstoneCholangitis3 more

The Institute of Imaged-Guided Surgery (IHU Strasbourg) has two clinical Magnetic Resonance Imaging (MRI) scanners, one with a 3T (3 Teslas) magnetic field used for diagnosis, the other with a magnetic field of 1,5T (1,5 Teslas) used for the interventional (Pre / per / postoperative). The reference for the visualization of the biliary and pancreatic ducts is a relatively long sequence that needs a breathing-synchronized acquisition leading to artefacts on the images (blur effect). In order to reduce and/or standardize the acquisition time as well as to limit artefacts, accelerated sequences are developed. Such sequence is available in France recently in the form of WIP Siemens (Work In Progress: sequence in test phase at manufacturer to be marketed in the short or medium term on clinical machines). It incorporates a Compressed Sensing (CS) acquisition scheme allowing the acquisition of a 3D (3 dimensions) sequence similar to the usual sequence by drastically reducing the acquisition time, the sequence CS-SPACE. This sequence exists in two forms: An ultra-rapid sequence acquired in apnea An accelerated sequence but remaining synchronized with the breath. The study carried out here on a large number of patients, with two different magnetic fields, applied routinely for diagnosis or anticipation of surgery, could be used by the community of radiologists, hepatogastroenterologists and also digestive surgeons Hepatobiliary.

Needlescopic Versus Transvaginal/Transumbilical Cholecystectomy

Calculus of Gallbladder With or Without CholecystitisLaparoscopic Cholecystectomy

Laparoscopic surgery has become the golden standard for the removal of the gallbladder. Recently, developments have been made so that operations can be performed through a natural orifice instead of the abdominal wall, thus minimizing the trauma of a procedure. This study compares the transvaginal/transumbilical cholecystectomy with the laparoscopic operation using 2-3mm instruments in female patients. It also examines the benefits and disadvantages related to postoperative pain, cosmetic aspects, and potential physiological alterations to the transvaginal approach that affect sexual intercourse.

Electrohydraulic Versus Laser Lithotripsy for Treatment of Difficult to Remove Biliary Stones

Gall Stones

Bile duct stones that can't be removed by conventional means can often be removed after fragmentation by shock waves (lithotripsy). The shock waves that are used for fragmentation of these stones are generated by electric sparks (electrohydraulic lithotripsy) or laser (laser lithotripsy). Although both techniques have been used for many years, there are no studies comparing the efficacy of the two. The purpose of this study is to find out which technique is more effective.

Short Duration Versus Fourteen Days Antibiotic in Common Bile Duct Cholangitis

Acute CholangitisCommon Bile Duct Calculi

Common bile duct stone cholangitis is a potentially fatal condition, characterized by an obstruction and bacterial infection of biliary system. The principles of management are appropriate biliary drainage and systemic antibiotics. There has been limited data about appropriate time of antibiotics in patient with successful endoscopic drainage.
