Prospective Randomized Comparative Study of New Single-incision Laparoscopic Cholecystectomy Technique, "Pick'n Roll", Versus Conventional Four-port Laparoscopic Cholecystectomy

简要总结

详细描述

A pilot study was conducted, with ten patients who were planned to perform laparoscopic cholecystectomy after approval by the ethics committee of Ondokuz Mayis University, Samsun, Turkey. Among ten patients, five patients were undergone LC, and another five were undergone SILC-PR. The sample size was calculated from the pilot study. Simple consecutive allocation method was used to randomly divide the subjects into LC (classical four port technique), and SILC-"Pick'n roll" (PR) beginning and experienced groups. Each group contained 20 patients. The randomization was achieved regardless of demographic characteristics, by Dr. N. O. One surgeon was performed all operation (Dr. R. A.). Patient's data were recorded by Dr. K. Y. At the end of the study, the data were analysed by Dr. S. C. and Dr. E. C. in a blinded manner to avoid bias Surgical Procedures The technique used for LC was the conventional four-trocar approach (10-mm optic at the umbilicus, 10-mm trocar in the epigastrium and two 5-mm trocars in the right upper abdomen). For SILC-PR, the patient was positioned supine on the operating table, once the access is gained into the abdomen, the patient re-positioned to reverse trendelenburg and left tilt. The surgeon stands on the left side of the patient and the assistant stands opposite him during the placement of the single-port device. SILC-PR was performed by the single-incision, single port technique using The OCTOTMPort (Dalimsurg, Seoul, Korea). The OCTOTMPort is a re-usable single-port device that contains two 5-mm, one 10-mm and one 12-mm port through the same port. Surgical access to the abdomen was obtained through an intraumbilical 2.5 cm incision from 12 o'clock to 6 o'clock. The OCTOTMPort was inserted and pneumoperitoneum was created up to an abdominal pressure of 15 mmHg. A 10-mm, 30º traditional scope (Karl Storz, Tuttlingen, Germany) was inserted through inferior placed 10-mm port, by the assistant who positioned on the patient's left side, and the peritoneal cavity was examined. If the stomach was distended, a nasogastric tube insertion was requested from the anesthesiologist. The surgeon introduced an Endo Grasp™ (Covidien, Mansfield, MA, USA) with left hand and elevated gallbladder fundus to assess the mobility of the gallbladder infindibulum, constant fundus retraction was used in whole operation by this instrument. In the presence of omental attachments, the gallbladder infindibulum was freed with monopolar hook device which holding by the surgeon's right hand, under the traction of the fundus. Once the gallbladder infindibulum freed from the attachments or clearly seen in first examination next step of the operation was launched. A 2.0 multifilament straight atraumatic needle was inserted through the surgeon's left of the falciform ligament with simultaneous palpation of the abdominal wall for optimum insertion site. The needle was grasped with a laparoscopic needleholder using by surgeon's right hand, and the needle was passed through the Hartmann's pouch at the lowest accessible point. To allow infindibulum retraction, wide triangulation and free Hartmann's pouch manipulation like "puppeteer movement", the passing suture with needle was turned around the afferent suture and a "half-knot" was created. The needle was passed back of the abdomen from the surgeon's left of the midclavicular line, with simultaneous palpation of the abdominal wall for optimum site. After this point, an assistant or a nurse was grasped two ends of the suspensory suture with clamps. With the help of fundus retraction and assistant's right or left hand dominant pulling tension on the suture, classical Hartmann's pouch retraction similar to LC technique was provided. Dissection of Calot's triangle and removal of gallbladder from the liver bed are possible in almost all cases with the use of aforementioned "Pick'n roll technique" and a hook diathermy.
