Introduction: Standard pressure pneumoperitoneum for laparoscopic cholecystectomy employs a pressure range of 12-14 mm Hg. An emerging trend has been the use of low pressure pneumoperitoneum in the range of 7-10 mm Hg in an attempt to lower the impact of pneumoperitoneum on the human physiology while providing adequate working space. Our study proposes to compare the use of low pressure pneumoperitoneum with the use of standard pressure pneumoperitoneum.
Methods: A randomised controlled trial consisting of 60 patients with symptomatic gallstone disease who underwent laparoscopic cholecystectomy, of which 30 patients were subjected to standard pressure pneumoperitoneum during the procedure and 30 patients to low pressure pneumoperitoneum.
Results: Both groups were comparable in all aspects. The mean operating time with low pressure pneumoperitoneum was 49.07 +/- 5.72 minutes and with standard pressure pneumoperitoneum was 46.43 +/- 6.92 minutes. There was no statistically significant change in blood pressure, heart rate, pain at 6 hours, need for additional analgesia or shoulder tip pain with the use of lower pressure pneumoperitoneum.
Conclusions: Low pressure pneumoperitoneum benefits the patient in the form of lower intensity of postoperative pain but it does not positively impact intraoperative hemodynamics.

Purpose Of Review: Post-laparoscopic shoulder pain (PLSP) can slow patient recovery and extend hospital stays, making its management crucial for patients undergoing laparoscopic surgery. Current consensus guidelines say little about how to prevent or manage PLSP. In this context, a multimodal approach to PLSP management that maybe extend beyond the pharmaceutical interventions currently employed.

Barotrauma is a medical condition caused by sudden pressure changes in the body causing damage to multiple parts of the body. However, it is an infrequent occurrence when it comes to Colo-rectal perforation, wherein the trauma occurs due to the insufflation of compressed air through the anus. Several factors influence the outcome of a patient with colonic perforation due to barotrauma such as the severity of the injury, hemodynamic status of the patient, the patient's general health and well-being, the time taken for active medical/ surgical intervention since the injury, aggressive intravenous antibiotics administration to prevent sepsis, post-operative complications like surgical site infection, post-op ileus, anastomotic leak, etc.

Purpose: In laparoscopic liver surgery, registering preoperative CT-extracted 3D models with intraoperative laparoscopic video reconstructions of the liver surface can help surgeons predict critical liver anatomy. However, the registration process is challenged by non-rigid deformation of the organ due to intraoperative pneumoperitoneum pressure, partial visibility of the liver surface, and surface reconstruction noise.
Methods: First, we learn point-by-point descriptors and encode location information to alleviate the limitations of descriptors in location perception.

Despite the benefits of minimally invasive surgery, interventions such as laparoscopic liver surgery present unique challenges, like the significant anatomical differences between preoperative images and intraoperative scenes due to pneumoperitoneum, patient pose, and organ manipulation by surgical instruments. To address these challenges, a method for intraoperative three-dimensional reconstruction of the surgical scene, including vessels and tumors, without altering the surgical workflow, is proposed. The technique combines neural radiance field reconstructions from tracked laparoscopic videos with ultrasound three-dimensional compounding.

Background: Surgical smoke generated by energy devices poses health risks to medical staff. During laparoscopic surgery, the smoke aggregating around the camera obstructs the visual field, forcing surgeons to interrupt surgery, and may increase surgical risk. We propose a proximal smoke evacuation method to improve surgical quality by effectively eliminating surgical smoke.
