RESUMO
@#Objective To summarize the efficacy of robot-assisted thoracic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) in the treatment of left upper lobectomy for non-small cell lung cancer. Methods The clinical data of patients with non-small cell lung cancer who underwent left upper lobectomy with RATS or VATS in our center from January 2019 to October 2021 were retrospectively analyzed. The patients were divided into two groups according to surgical methods: a RATS group and a VATS group. The baseline clinical data and results were compared between the two groups. Results A total of 145 patients were included. There were 78 males and 67 females with a mean age of 59.9 years. There were 63 patients in the RATS group and 82 patients in the VATS group. There was no death within 30 days after operation in both groups. In the RATS group, the drainage volume on the second postoperative day (233.49±83.94 mL vs. 284.88±120.21 mL, P=0.003), total operative time (126.94±29.50 min vs. 181.59±61.51 min, P=0.000), intraoperative resection time of the left upper lobe (76.48±27.52 min vs. 107.23±47.84 min, P=0.000), intraoperative blood loss (P=0.000), and conversion rate to thoracotomy (P=0.018) were significantly better than those in the VATS group. The group (5.41±0.94 groups vs. 4.83±1.31 groups, P=0.002) and number (18.27±7.39 vs. 12.76±6.54, P=0.000) of dissected lymph nodes in the RATS group were significantly more than those in the VATS group. The differences in the drainage volume on the first day after operation, postoperative intubation time, postoperative hospital stay or postoperative complications between the two groups were not statistically significant (P>0.05). Conclusion The application of RATS in the left upper lobectomy for non-small cell lung cancer is safe and feasible, and has obvious advantages over VATS.
RESUMO
@#Objective To summarize the clinical experience of Da Vinci robotic-assisted left upper lobectomy for treating lung cancer. Methods We retrospectively analyzed the perioperative data of 33 patients with primary lung cancer who underwent Da Vinci robotic-assisted left upper lobectomy between December 2016 and December 2018 in our hospital. Meanwhile, the perioperative data of 41 patients with lung cancer who underwent video-assisted thoracoscopic left upper lobectomy during the same period by the same surgeon were studied as a control group. The resection was followed by the principle of "from back down to front up" way. Systemic lymph node dissection including No.4-9 was performed for all patients. Results All patients received successful surgery with no case of conversion to thoracotomy and perioperative death. Comparing to video-assisted thoracoscopic surgery, the Da Vinci robotic-assisted left upper lobectomy had longer operating time (191.21±61.77 min vs. 154.51±38.81 min, P=0.003), more cost (82 307.75±11 859.03 yuan vs. 58 966.57±5 640.07 yuan, P=0.000), shorter chest tube duration (4.58±1.77 d vs. 5.41±1.52 d, P=0.031) and postoperative hospital stay (6.48±1.82 d vs. 7.66±2.12 d, P=0.014). However, there was no significant difference between the two groups regarding to blood loss, lymph node dissection, postoperative pain score, total chest drainage volume, chest drainage volume per day and the rate of pulmonary complications. Conclusion The Da Vinci robotic-assisted left upper lobectomy for treating lung cancer is safe and more minimally invasive, but more expensive.
RESUMO
Pericardial tamponade limits diastolic filling of the heart; therefore, a high venous pressure is required to fill the ventricle. In presence of cardiac tamponade, therapeutic agents and manoeuvres that results in venodilation or vasodilation can severely compromise diastolic filling of the heart and might result in rapid cardiac decompensation. Equalization of central venous pressure and pulmonary artery diastolic pressure or equalization of pressures in all four chambers during diastole confirms cardiac tamponade. Transthoracic echocardiography can detect the site of tamponade and assist in pericardiocentesis. We describe acute pericardial tamponade in a young man who underwent left posterolateral thoracotomy for left upper lobectomy. Intraoperatively, mobilization of the left upper lobe was frequently associated with hypotension. Postoperatively, the patient suffered two more episodes of hypotension. The episodes of hypotension were attributed to surgical manipulation and epidural blockade. Hemodynamics normalized after discontinuing epidural infusion, volume resuscitation and lobectomy. On third postoperative day, the patient developed cardiovascular collapse; arterial blood pressure and central venous pressure were 70/50 and 12 mmHg. Investigations showed haziness of left lung, and severe respiratory acidosis. On opening of the left thoracotomy wound, pericardial tamponade was diagnosed. A pericardial window was created and tamponade was released with that the hemodynamics normalized. Episodes of unexplained hypotension after left upper lobectomy suggest a cardiac etiology and acute pericardial tamponade is a possibility which should be released immediately otherwise it can result in fatal outcome.
