Active clinical trials for "Cholelithiasis"

Analgesic efficacy of multi-modal analgesia is superior to standard analgesia for patients undergoing elective laparoscopic cholecystectomy for symptomatic cholelithiasis. Topical cystic plate and port-site incision 0.25% bupivacaine significantly reduces pain after laparoscopic cholecystectomy.

The purpose of this study is to determine the effect of warmed, humidified carbon dioxide Insufflation vs standard carbon dioxide in laparoscopic cholecystectomy.

Many feasibility studies have been published on Single Port surgery, but no comparative studies have shown any advantages compared to standard laparoscopy. The purpose of this study is to compare the clinical outcomes and economical issues of laparoscopic cholecystectomies using single port transumbilical approach and three trocars.

The purpose of this study is to determine the effects of intraperitoneal administration of levobupivacaine on pain after laparoscopic cholecystectomy.

Prospective randomized trial of single incision versus standard 4 port laparoscopic cholecystectomy. Hypothesis is that the operative time will be longer with single incision.

The purpose of the study is to determine the feasibility of cholecystectomy made by a transvaginal approach with a NOTES procedure (natural orifice translumenal endoscopic surgery).

This study aims to evaluate post-operative pain in single-incision laparoscopic cholecystectomy (SILC) versus the conventional four port technique (LC). The investigators hypothesize that SILC is non-inferior in post-operative pain.

While there exists consensus among surgeons that patients with gallstone pancreatitis should undergo cholecystectomy to prevent recurrence, the precise timing of laparoscopic cholecystectomy for mild to moderate disease remains controversial. We hypothesize that laparoscopic cholecystectomy performed within 48 hours of admission, regardless of resolution of abdominal pain or abnormal laboratory values, will result in a shorter hospital stay.

The trial compares minilaparotomy (small-incision) cholecystectomy with (key-hole) laparoscopic cholecystectomy by randomly allocating patients with gallbladder disease to two groups of surgeons, each group being trained for one of the two methods.

We have designed a new method which could be used in laparoscopic cholecy- stectomy.Account to this new method, the three incisions are all located on the lower abdominal, theoretically it could get more beautiful outlook and less stress response than traditional laparoscopic cholecystectomy(two of the three incisions located on upper abdomen) or single port laparoscopic cholecystectomy(one large incision located on umbilicus). We plan to conduct a randomized controlled trial to compare those there methods of laparoscopic cholecystectomy, in order to find out if there will be some advantages of this new method,such as in lowering the stress response,reducing impact on respiration, relieving post-operation pain and improving appearance.
