Preaponeurotic endoscopic repair (REPA) indication in men could be controversial.

PURPOSE: To evaluate the outcomes of REPA and establish if any differences in complications and evolution are present between males and females. METHODS: A retrospective study including consecutive patients operated by REPA approach between November 2017 and April 2019 was conducted. Demographic data, operative times, postoperative complications, and hospital stay were analyzed. The EuraHS-QoL score was used to assess postoperative pain, daily activity constraints, and aesthetic discomfort. The results were compared between sexes. Statistical analysis was performed using SPSS 19. RESULTS: Fifty-four patients were included and 53.7% were male. Patients had a mean age of 50.7 years and a mean BMI of 28.7. The average RAD (Rectus Abdominis Diastasis) size was 2.6 cm (range of 2-5 cm). Seroma was significantly more frequent in males, with an incidence of 55.2 and 24% for females (p = 0.02). Three cases required reintervention (5.5% of total cases), which corresponded to a cystic seroma, an abdominal wall hematoma, and a hernia recurrence. The three cases were males and a p value of 0.04 was obtained when comparing reintervention rates between males and females. No cases of surgical wound infection nor cutaneous necrosis were recorded. No conversions were needed. The mean postoperative pain was 2.25, the mean daily activity constraints score was 2.63, and the degree of aesthetic discomfort was 1.23 with no significant differences between groups. CONCLUSION: The correction of small midline defect associated with minor RAD using REPA seems feasible and reproducible. REPA had achieved good results in females, but in males, the outcomes were poorer.

Laparoscopic Liver Resection: A South American Experience with 2887 Cases.

BACKGROUND: Laparoscopic liver resections (LLR) have been increasingly performed in recent years. Most of the available evidence, however, comes from specialized centers in Asia, Europe and USA. Data from South America are limited and based on single-center experiences. To date, no multicenter studies evaluated the results of LLR in South America. The aim of this study was to evaluate the experience and results with LLR in South American centers. METHODS: From February to November 2019, a survey about LLR was conducted in 61 hepatobiliary centers in South America, composed by 20 questions concerning demographic characteristics, surgical data, and perioperative results. RESULTS: Fifty-one (83.6%) centers from seven different countries answered the survey. A total of 2887 LLR were performed, as follows: Argentina (928), Brazil (1326), Chile (322), Colombia (210), Paraguay (9), Peru (75), and Uruguay (8). The first program began in 1997; however, the majority (60.7%) started after 2010. The percentage of LLR over open resections was 28.4% (4.4-84%). Of the total, 76.5% were minor hepatectomies and 23.5% major, including 266 right hepatectomies and 343 left hepatectomies. The conversion rate was 9.7%, overall morbidity 13%, and mortality 0.7%. CONCLUSIONS: This is the largest study assessing the dissemination and results of LLR in South America. It showed an increasing number of centers performing LLR with the promising perioperative results, aligned with other worldwide excellence centers.
