BackgroundSince the introduction of laparoscopic surgery, it has become more popular with many advantages over open surgery including faster recovery, shorter hospital stays, and decreased tissue trauma. Despite its benefits, laparoscopic surgery can result in its own unique complications, such as the formation of a trocar site hernia (TSH), which have been reported in approximately 0–1.0% of laparoscopic cases when using non-bladed trocars.MethodsA literature review was performed from June 1990 to June 2019. PubMed was searched using the keywords “laparoscopic surgery,” “trocar site hernia,” and “port site hernia.” Only articles in English were identified but not limited to the USA.ResultsThe total number of patients in all articles was 18,533 with a mean follow-up period of 22.50 ± 1.76 months. The overall trocar site hernia rate was 0.104%. When comparing open vs. closed ports, there was no significant difference in the hernia incidence rate for 5-mm and 10-mm ports. When comparing bladed versus non-bladed trocars left open, there was a statistically significant difference with lower hernia incidence rates for non-bladed trocars over bladed trocars for 5-mm, 10-mm, and 12-mm ports. And when comparing trocar location from midline versus off-midline, there was a statistically significant higher TSH incidence in midline trocar locations.ConclusionResults suggest that TSH rate is lower when using non-bladed trocars for any size of trocar. When comparing whether fascial closure had an effect, the 5-mm and 10-mm ports had no difference in incidence rates and leaving the fascia open can reduce operative time, risk of needlestick injuries, and overall procedural cost. In addition, trocars at midline locations resulted in higher TSH incidence rates. Future research is still needed to assess for other factors that may influence hernia formation and how it can be minimized.

PurposeTo compare clinical pregnancy rates and live birth rates of single blastocyst transfers performed by attending physicians or fellows in reproductive endocrinology and infertility program.MethodsRetrospective study in an academic reproductive center. We evaluated 932 fresh single blastocyst transfer cycles performed by fellows in training (389 embryo transfers) and by attending physicians (543 embryo transfers).ResultsThere were no differences in the baseline characteristics and IVF cycle parameters between patients who had transfers performed by fellows or attending physicians. Transfers performed by attending physicians or fellows resulted in similar CPR (46.5 vs. 42.9%, p = 0.28) and LBR (38.3 vs. 34.2%, p = 0.11). Multivariate logistic regression analysis showed that even after adjusting for possible confounders (age, gravity, parity, baseline FSH, antral follicle count, dose of gonadotropins, stimulation protocol, and quality of embryo transferred), CPR (OR 0.81, CI 0.62–1.07) and LBR (OR 0.79, CI 0.6–1.05) in the two groups were comparable.ConclusionClinical pregnancy rate and live birth rate after embryo transfer performed by attending staffs or fellows are comparable. This finding reassures fellowship programs that allowing fellows to perform embryo transfers does not compromise the outcome.
