Laparoscopic cystogastrostomy is a well-accepted minimally invasive modality to treat pancreatic pseudocysts. There has been one prior report of cystogastrostomy via single incision laparoscopic surgery (SILS) in which specialized instrumentation and access platforms were used.We report the challenges encountered in a low resource setting with the SILS approach to drainage using only standard l...

PURPOSE To further improve the advantages of minimally invasive surgery, single port laparoscopic techniques continue to be developed. We report our initial experience with single port laparoscopic appendectomy (SPLA) in children and compare its outcomes to those of conventional laparoscopic appendectomy (CLA). METHODS Clinical data were prospectively collected for SPLA cases performed at Chu...

During a laparoscopic surgery, the endoscope can be manipulated by an assistant or a robot. Several teams have worked on the tracking of surgical instruments, based on methods ranging from the development of specific devices to image processing methods. We propose to exploit the instruments' insertion points, which are fixed on the patients abdominal cavity, as a geometric constraint for the lo...

PURPOSE To confirm the feasibility of the laparoendoscopic Pfannenstiel nephrectomy using conventional laparoscopic instruments. MATERIALS AND METHODS Since March 2009, laparoscopic nephrectomy through a Pfannenstiel incision has been performed in selected patients in our service. The Veress needle was placed through the umbilicus which allowed carbon dioxide inflow. One 5 mm (or 10 mm) troca...

Two experiments aiming at comparing palpation with gloved fingers, conventional laparoscopic instruments, and a laparoscopic instrument with a sensor array attached to its end effector are described. The sensor array provides the surgeon with visually presented tactile information. Fifteen subjects were asked to discriminate hardness and size of objects (rubber balls hidden in pig's intestine) ...

and the creative use of the newly developed solid state, charge coupled device (CCD) cameras, laparoscopes, clip appliers, and energy sources enabled the laparoscopic revolution of the 1990s. And, without doubt, evolving technology will sustain the development of minimally invasive surgery. But the technology that fueled the laparoscopic revolution is aged and now hinders further advances in th...

A brief biography of Kurt Semm, the pioneer of laparoscopic appendectomy and inventor of various laparoscopic instruments are done, with special reference to his struggle to establish the foundation of minimally invasive surgery amongst his contemporary surgeons.

background: laparoscopy or minimally invasive surgery is a surgical procedure in which laparoscope and other surgical instruments are inserted inside body via a few small incisions. laparoscope is used to look inside the patient's body and records displayed images. temporal segmentation of laparoscopic videos has many applications like detecting laparoscopic anomalies and interrupts. it is prer...

HYPOTHESIS Performing complex tasks requires greater muscle effort with laparoscopic instruments than with open surgical instruments. DESIGN A nonrandomized 2-condition trial. SETTING A semienclosed ergonomics station in the exhibit hall at the Annual Meeting of the Society of American Gastrointestinal Endoscopic Surgeons. SUBJECTS Twenty-one surgeons volunteered to participate in the stu...
