NCT ID: NCT00892879 Completed - Clinical trials for Cholecystectomy, Laparoscopic

A Trial of Single Port Laparoscopic Cholecystectomy Versus Four Port Laparoscopic Cholecystectomy

Start date: February 2009
Phase: Phase 3
Study type: Interventional

This is a single-institution, prospective, one-to-one randomized controlled research study. Subjects medically determined to need a cholecystectomy will be consented for surgery and study participation prior to enrolment in this study. Patients will then be randomized to receive either a single port laparoscopic cholecystectomy or a four port laparoscopic cholecystectomy.

NCT ID: NCT00848146 Completed - Endoscopy Clinical Trials

NOTES-Assisted Laparoscopic Cholecystectomy Surgery

TAS-NOTES
Start date: February 2009
Phase: N/A
Study type: Interventional

Refinements in laparoscopic surgery, coupled with advancements in therapeutic flexible endoscopy, have set the stage for surgery to move to even less invasive techniques to treat conditions in the GI tract and peritoneal cavity. Natural orifice translumenal endoscopic surgery (NOTES) offers a means of reducing and ultimately eliminating the need for abdominal incisions to gain access to the peritoneal cavity. In NOTES, a flexible endoscope and accessory instruments are inserted through a natural body orifice and passed through the wall of an organ to reach the abdominal cavity. By reducing or eliminating the need for abdominal incisions, NOTES may provide a least invasive surgical option that can reduce pain, recovery time, complications, and systemic inflammatory response when compared to a laparoscopic surgical approach. In this study, we propose to use the NOTES technique to eliminate the need for a 1.5-2.5 cm umbilical incision. Hypothesis 1: We hypothesize that a combined endoscopic and laparoscopic approach will be able to eliminate a 1.5 to 2.5 cm infraumbilical incision when performing a laparoscopic cholecystectomy. Hypothesis 2: Closure of the gastrotomy will be facilitated with the Ethicon TAS system.

NCT ID: NCT00288899 Completed - Surgery Clinical Trials

Benefits of 'Repeat Back' Protocols Within A Computer-Based Informed Consent Program

Start date: August 7, 2006
Phase: Phase 1
Study type: Interventional

This is a VA Merit Review Study involving 7 VA medical centers participating in a parallel group randomized trial comparing "repeat back" versus standard electronic consent for 4 common elective surgical procedures (total hip arthroplasty, carotid endarterectomy, laparoscopic cholecystectomy, and radical prostatectomy). Baseline covariates include health status (SF-12), reading ability (REALM), and demographics. Primary outcomes are patient comprehension of the informed consent, patient satisfaction with the informed consent and decision making processes, patient satisfaction with care, anxiety (STAI), and provider assessment of the "repeat back" process. In addition, we are electronically capturing data detailing time spent in each phase of the consent process including "repeat back".
