Pleural injury during laparoscopic renal surgery: early recognition and management

Pneumothorax during retroperitoneal laparoscopic partial nephrectomy in a lupus nephritis patient: A case report

BACKGROUND

Downgrading target treatment and laparoscopic partial nephrectomy have become increasingly popular in patients with renal cell carcinomas. Rare as it is, pneumothorax is one of the most severe intraoperative complications which needs immediate recognition. On the other hand, as a rheumatological disease, lupus nephritis requires a long period of hormone therapy. Cases of pneumothorax in hormone-consuming renal cancer patients are even fewer.

CASE SUMMARY

A 39-year-old woman was admitted to our department to take a laparoscopic partial nephrectomy. The patient had a medical history of lupus nephritis and renal clear cell carcinoma with hormone and target treatment. Her blood oxygen saturation dropped to 92% during the operation, and pneumothorax was detected by ultrasound. O₂ inhalation and lung dilation were performed. Her vital signs were monitored closely throughout the operation. The operation was accomplished, and she regained consciousness smoothly. A postoperative bedside chest X-ray was conducted after she was transferred to the urosurgery ward, while no evidence of further pneumothorax or lib injury was observed.

CONCLUSION

Pneumothorax is a severe complication in laparoscopic or robotic-assisted laparoscopic operations, especially in retroperitoneal ones. It is easily neglected unless the injury of the diaphragm is found. Low insufflation pressure and shorter operation time are necessary for patients with a history of long-term hormone consumption or chronic immune system disease.

Pneumoperitoneum-induced pneumothorax during laparoscopic living donor hepatectomy: a case report

Background

We present a living donor case with an unexpected large-volume pneumothorax diagnosed using lung ultrasound during a laparoscopic hepatectomy for liver transplantation (LT).

Case presentation

A 38-year-old healthy female living donor underwent elective laparoscopic right hepatectomy. The preoperative chest radiography (CXR) and computed tomography images were normal. The surgery was uneventfully performed with tolerable CO₂ insufflation and the head-up position. SpO₂ decreased and airway peak pressure increased abruptly after beginning the surgery. There were no improvements in the SpO₂ or airway pressure despite adjusting the endotracheal tube. Eventually, lung ultrasound was performed to rule out a pneumothorax, and we verified the stratosphere sign as a marker for the pneumothorax. The surgeon was asked to temporarily hold the surgery and cease with the pneumoperitoneum. Portable CXR verified a large right pneumothorax with a small degree of left lung collapse; thus, a chest tube was inserted on the right side. The hemodynamic parameters fully recovered and were stable, and the surgery continued laparoscopically. The surgeon explored the diaphragm and surrounding structures to detect any defects or injuries, but there were no abnormal findings. The postoperative course was uneventful, and a follow-up CXR revealed complete resolution of the two-sided pneumothorax.

Conclusion

This living donor case suggests that a pneumothorax can occur during laparoscopic hepatectomy due to the escape of intraperitoneal CO₂ gas into the pleural cavity. Because missing the chance to identify a pneumothorax early significantly decreases the safety for living donors, point-of-care lung ultrasound may help attending physicians reach the final diagnosis of an intraoperative pneumothorax more rapidly and to plan the treatment more effectively.

Carbon dioxide pneumothorax following retroperitoneal laparoscopic partial nephrectomy: a case report and literature review

Background

Laparoscopy has many advantages when used to assist surgery. However, pneumothorax, as a rare but potentially life-threatening complication, it requires rapid recognition and treatment. CO₂ pneumothorax may be distinct from air pneumothorax. Here we present a case with unexpected large and symptomatic CO₂ pneumothorax and treated successfully in a conservative way.

Case presentation

A 27-year-old woman who was scheduled a laparoscopic partial nephrectomy received general anesthesia. At the end of surgery, she waked up and got spontaneous breathing. However, she developed a sudden fall in SpO₂ (approximately 30%) and blood pressure with subsequent unconsciousness after switching mechanical ventilation to spontaneous mode. With immediate manual ventilation, SpO₂ and blood pressure recovered simultaneously and the patient regained consciousness. Point-of-care chest X-ray revealed a large, right pneumothorax occupying 70% of the hemi-thorax. Without chest drainage, she was extubated in the operating room and treated with supplemental facial mask oxygen therapy in PACU. On the postoperative 5th day, she was discharged without any further complication.

Conclusion

Retroperitoneal laparoscopic surgeries are likely to bring about severe capno-thorax, which could be absorbed rapidly. Chest X-ray could be used to assist diagnosis but point-of-care transthoracic ultrasound is recommended. Even severe capno-thorax could be treated conservatively. This case highlights the awareness and therapeutic choice of noninvasive management for capno-thorax.

Laparoscopy in trauma: An overview of complications and related topics

The introduction of laparoscopy has provided trauma surgeons with a valuable diagnostic and, at times, therapeutic option. The minimally invasive nature of laparoscopic surgery, combined with potentially quicker postoperative recovery, simplified wound care, as well as a growing number of viable intraoperative therapeutic modalities, presents an attractive alternative for many traumatologists when managing hemodynamically stable patients with selected penetrating and blunt traumatic abdominal injuries. At the same time, laparoscopy has its own unique complication profile. This article provides an overview of potential complications associated with diagnostic and therapeutic laparoscopy in trauma, focusing on practical aspects of identification and management of laparoscopy-related adverse events.

[Nephrectomy: complication management]

BACKGROUND

Nephrectomy is a standard procedure that is associated with a low complication rate.

OBJECTIVES

Based on an analysis of the literature, expert recommendations, and our own experience, the management of complications during and after nephrectomy is described.

RESULTS

Complications during and after nephrectomy can be avoided by careful surgical planning, optimal approach and exposure, and precise knowledge of the principles of anatomy. The treatment of bleeding complications and injuries to neighboring structures are essential elements in the management of complications. Hernia and relaxation of the lumbar muscles should be avoided.

CONCLUSION

Morbidity associated with nephrectomy can be reduced by careful surgical planning and paying attention to the basic anatomical and surgical principles.

Intraoperative complications of laparoscopic adrenalectomy

A laparoscopic or retroperitoneoscopic access to the adrenal gland is the standard of care for adrenalectomy in most cases. Although in laparoscopic adrenalectomy the approach is minimally invasive, the procedure is challenging. This is reflected in the scope of possible complications. The surgeon must consider complications related to the anatomical topography of the adrenal gland, which typically encompasses the complications known from open surgery and complications related to the minimal invasive access. In this topic paper we will address the most frequently encountered complications of adrenalectomy: vascular injuries, injuries of the bowel, pleural tears, and injuries to the liver, spleen and pancreas. Fortunately, these complications occur rarely. However, many of these complications can have devastating consequences. Therefore, it's the surgeon's obligation to be aware of the possible complications he might encounter during laparoscopic adrenalectomy. This awareness is essential for their prevention and it helps the laparoscopic surgeon to identify complications intraoperatively.

Laparoscopic surgery: pitfalls due to anesthesia, positioning, and pneumoperitoneum

BACKGROUND

Laparoscopic procedures are increasing in number and extensiveness. Many patients undergoing laparoscopic surgery have coexisting disease. Especially in patients with cardiopulmonary comorbidity, pneumoperitoneum and positioning can be deleterious. This article reviews possible pitfalls related to the combination of anesthesia, positioning of the patient, and the influence of pneumoperitoneum in the course of laparoscopic interventions.

METHODS

A literature search using Medline's MESH terms was used to identify recent key articles. Cross-references from these articles were used as well.

RESULTS

Patient positioning and pneumoperitoneum can induce hemodynamic, pulmonary, renal, splanchnic, and endocrine pathophysiological changes, which will affect the entire perioperative period of patients undergoing laparoscopic procedures.

CONCLUSION

Perioperative management for the estimation and reduction of risk of morbidity and mortality due to surgery and anesthesia in laparoscopic procedures must be based on knowledge of the pathophysiological disturbances induced by the combination of general anesthesia, pneumoperitoneum, and positioning of the patient.
