Single port laparoscopic surgery is changing the standard of care in surgical care like nothing since the laparoscopic technique was introduced 20 years ago. We present out technique of single port donor nephrectomy using the Gelpoint device. We have successfully performed this surgery in 100 patients.

2026
This protocol presents robotic duodenum-preserving total pancreatic head resection (R-DPPHRt) for intraductal papillary mucinous neoplasms (IPMNs). A video demonstrates the technique in a patient with main duct-IPMN, highlighting its feasibility as a minimally invasive, organ-preserving alternative to pancreaticoduodenectomy.

Intraoperative Gastroscopy for Tumor Localization in Laparoscopic Surgery for Gastric Adenocarcinoma

In early gastric cancer, the aim of surgery is to precisely remove the distal stomach including the primary tumor. To do this, accurate localization of the tumor is crucial, especially in totally laparoscopic surgery. This protocol describes a procedure for intraoperative gastroscopy in totally laparoscopic subtotal gastrectomy.

Pericardiocentesis

Source: Rachel Liu, BAO, MBBCh, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA The heart lies within the pericardium, a relatively inelastic fibrous sac. The pericardium has some compliance to stretch when fluid is slowly introduced into the pericardial space. However, rapid accumulation overwhelms pericardial ability to accommodate extra fluid. Once a critical volume is reached, intrapericardial pressure increases dramatically, compressing the right ventricle and...
FAQs
During laparoscopy, carbon dioxide introduced through a trocar expands the abdomen and creates more working room. This increased space improves the surgeon’s view of internal structures and allows instruments to move more effectively. The gas therefore serves a procedural purpose, helping clinicians perform minimally invasive operations rather than indicating disease by itself.
The same imaging finding can have different clinical meanings depending on whether gas was deliberately introduced during a recent laparoscopic procedure or escaped from a perforated gastrointestinal organ. Recent procedures provide essential context, while symptoms and examination findings help determine whether the finding reflects an expected operative change or a potentially dangerous abdominal problem.
Gas escaping through a perforated gastrointestinal organ may signal a serious underlying abdominal injury or disease. Clinicians therefore interpret free intraperitoneal gas together with the patient’s symptoms and physical examination rather than treating the imaging finding in isolation. This combined assessment helps identify situations that may require emergency surgery and treatment of the underlying cause.
For minimally invasive surgery, clinicians introduce carbon dioxide through a trocar to expand the abdomen before or during the laparoscopic procedure. The expanded space supports visualization and instrument movement, allowing the operation to proceed through small access points. The procedural context is important later if imaging shows intraperitoneal gas during postoperative assessment.
Upright radiography, computed tomography, and ultrasound can help identify free intraperitoneal gas. These methods provide detection that supports the clinical evaluation, but the imaging result does not by itself establish the cause or determine management. Clinicians combine the findings with symptoms, examination results, and any recent procedure to guide the next decision.
Management depends on the overall clinical context and the suspected source of the gas. When symptoms, examination findings, imaging, and procedural history suggest a perforated gastrointestinal organ, urgent evaluation may lead to emergency surgery and treatment of the underlying cause. In other circumstances, clinicians may choose observation while continuing to interpret the finding in context.
