Background Trocar Site Hernia (TSH) seems to represent a rare surgical complication, but available data are based only on symptomatic patients and clinically diagnosed cases; moreover, no data are available concerning TSH incidence after robotic-assisted procedures. Aims of the study were to asses TSH incidence in obese patients who underwent Roux-en-Y gastric bypass (RYGB) and to compare it between robotic-assisted and standard laparoscopy. Methods Patients who underwent RYGB between November 2007 and June 2012 underwent a clinical examination and an ultrasonography study of the abdominal wall by a single operator. Results 150 patients entered the study, 102 in the laparoscopic and 48 in the robotic group. Mean pre-operative weight and BMI were 129.3?kg and 47.4?kg/m2, respectively; both were higher in the laparoscopic group (134.7 vs 117.6?kg, p?2, p?p?p?=?0.195). There were no significant differences between patients with and without TSH, except for higher post-operative wound complication in patients without TSH (22 vs 6.8?%, p?=?0.024; OR 0.26). Conclusions TSH revealed a high incidence in a bariatric surgery population, suggesting that it represents a strongly underestimated complication; furthermore, the present study showed a trend towards a higher incidence of TSH in patients who underwent robotic-assisted bariatric surgery.
