BACKGROUND:The use of various biological and non-biological simulators is playing an important role in training modern surgeons with laparoscopic skills. However, there have been few reports of the use of a fresh porcine cadaver model for training in laparoscopic surgical skills. The purpose of this study was to report on a surgical training seminar on reduced port surgery using a fresh cadaver porcine model and to assess its feasibility and efficacy.MATERIALS AND METHODS:The hands-on seminar had 10 fresh porcine cadaver models and two dry boxes. Each table was provided with a unique access port and devices used in reduced port surgery. Each group of 2 surgeons spent 30 min at each station, performing different tasks assisted by the instructor. The questionnaire survey was done immediately after the seminar and 8 months after the seminar.RESULTS:All the tasks were completed as planned. Both instructors and participants were highly satisfied with the seminar. There was a concern about the time allocated for the seminar. In the post-seminar survey, the participants felt that the number of reduced port surgeries performed by them had increased.CONCLUSION:The fresh cadaver porcine model requires no special animal facility and can be used for training in laparoscopic procedures.

Laparoscopic transgastric stapler-assisted mucosectomy (SAM) has been described for minimally invasive circumferential en bloc resection of Barrett's esophagus (BE). Conceivably long-term disease control might be achieved by adding antireflux surgery after resection of BE by SAM. The aim of this study was to assess the feasibility of combined SAM and fundoplication in one laparoscopic procedure in six pigs. Furthermore, the competence of the gastroesophageal junction (GEJ) was assessed at baseline, after SAM, and after subsequent laparoscopic fundoplication. At each measuring point reflux measurements were repeated 6 times in each pig. Blue-colored water was infused into the stomach to provoke reflux. Intragastric yield pressure and volume were recorded until drainage of blue solution (DBS) was noted. Time to reflux was measured by DBS and by multichannel intraluminal impedance (MII). In all animals SAM followed by laparoscopic fundoplication was feasible in a single session. A weakening of the GEJ was found after SAM, indicated by decreased yield pressure (11.5 mmHg vs. 8.5 mmHg; P < 0.001), time to DBS (90 seconds vs. 60 seconds; P = 0.008) and MII (80 seconds vs. 33 seconds; P < 0.001). After additional Nissen fundoplication the GEJ competence was restored, with measurements returning to baseline values (time to DBS 99 seconds; P = 0.15; MII 76 seconds; P = 0.84). The yield pressure increased from 11.5 mmHg at baseline to 19.7 mmHg after SAM and fundoplication (P < 0.001). Laparoscopic fundoplication and SAM may be combined in a single laparoscopic session. Although the GEJ was weakened after SAM, Nissen fundoplication restored the GEJ as an effective reflux barrier in this experiment. For clinical validation, the results need to be confirmed in a prospective human trial.

Perineal sigmoidopexy utilizing transanal endoscopic microsurgery (TEM) to treat full thickness rectal prolapse: a feasibility trial in porcine and human cadaver models

Abstract: TEM sigmoidopexy is technically feasible. This approach has the potential to reduce the recurrence rate associated with perineal approaches alone, but further study is needed to confirm this hypothesis.
