    Abstract Background: Laparoscopic ventral and incisional hernia mesh repair (LVIHR) has become the standard of care due to shorter recovery time, low rate of complication and recurrence. The most common fixation technique for mesh is by tackers but results in patients having more pain in the early postoperative period. One modality to reduce pain has been to use intracorporeal conventional sutures but with the disadvantage of inherent difficulty in handling, suturing and knotting which is obviated by barbed sutures.
    Methods: The study was conducted over a period of two years. Sixty patients with primary ventral and incisional hernia were randomized to either fixation of mesh with barbed sutures or to tackers with transfacial sutures. Primary end points were used to evaluate and compare mesh fixation time, early postoperative pain and complications, whereas secondary end points were used to compare the incidence of chronic pain and recurrence.
    Results: Of the 60 patients, 51% had primary ventral hernia, and the rest had incisional hernia. Visual Analogue Scale (VAS) pain score for the barbed suture group at all intervals postoperatively was significantly lower than that for tackers. The mean time taken for fixation in the tacker group was significantly lower. Only one patient under the tacker group developed recurrence.
    Conclusion: Barbed suture group had significantly less pain and is economical with the same rates of recurrence as compared with tackers. Hence, low pain scores, cost effectiveness and relatively easier intracorporeal suturing make barbed sutures a viable alternative for intracorporeal mesh fixation in LVIHR.

    Abstract Reward and representation learning are two long-standing challenges for learning an expanding set of robot manipulation skills from sensory observations. Given the inherent cost and scarcity of in-domain, task-specific robot data, learning from large, diverse, offline human videos has emerged as a promising path towards acquiring a generally useful visual representation for control; however, how these human videos can be used for general-purpose reward learning remains an open question. We introduce $\textbf{V}$alue-$\textbf{I}$mplicit $\textbf{P}$re-training (VIP), a self-supervised pre-trained visual representation capable of generating dense and smooth reward functions for unseen robotic tasks. VIP casts representation learning from human videos as an offline goal-conditioned reinforcement learning problem and derives a self-supervised dual goal-conditioned value-function objective that does not depend on actions, enabling pre-training on unlabeled human videos. Theoretically, VIP can be understood as a novel implicit time contrastive objective that generates a temporally smooth embedding, enabling the value function to be implicitly defined via the embedding distance, which can then be used to construct the reward for any goal-image specified downstream task. Trained on large-scale Ego4D human videos and without any fine-tuning on in-domain, task-specific data, VIP's frozen representation can provide dense visual reward for an extensive set of simulated and $\textbf{real-robot}$ tasks, enabling diverse reward-based visual control methods and significantly outperforming all prior pre-trained representations. Notably, VIP can enable simple, $\textbf{few-shot}$ offline RL on a suite of real-world robot tasks with as few as 20 trajectories.
