ReviewNear-infrared fluorescence imaging for real-time intraoperative anatomical guidance in minimally invasive surgery: a systematic review of the literature.
Near-infrared fluorescence (NIRF) imaging, using contrast agents with fluorescent characteristics in the near-infrared (NIR: 700-900 nm) window, is considered to possess great potential for clinical practice in the future of minimally invasive surgery (MIS), given its capacity for intraoperative, real-time anatomical navigation, and identification. The aim of this review is to provide an overview of the literature concerning the current and potential future applications of fluorescence imaging in supporting anatomical guidance during MIS, and thereby guiding future research. ⋯ Future implementation of new intraoperative optical methods, such as NIRF, could significantly contribute to intraoperative anatomy navigation and facilitate critical decision-making in MIS. Further research (i.e., large multi-center randomized controlled trials) is needed to establish the true value of this innovative optical imaging technique in standard clinical practice.

Postoperative hyperbilirubinemia suggests the occurrence of complications after esophagectomy for esophageal cancer.
Serum bilirubin levels frequently increase after esophagectomy for esophageal cancer. Several studies have reported hyperbilirubinemia in patients with postoperative complications. We aimed to perform a detailed large-scale analysis to clarify this association. ⋯ Although various factors impact postoperative hyperbilirubinemia, postoperative complications were most significantly associated with postoperative hyperbilirubinemia. Patients with postoperative hyperbilirubinemia after esophagectomy must be managed more carefully because unnoticed complications may be associated with hyperbilirubinemia.

Risk factors for incisional and organ space surgical site infections after liver resection are different.
Surgical site infection (SSI) is a common cause of major morbidity after liver resection. This study aimed to identify the risk factors for incisional and organ/space SSIs after liver resection. ⋯ High ASA scores, anemia, chronic hepatitis or liver cirrhosis, and prolonged operations increased the risk of incisional SSIs; concomitant bowel surgery increased the risk of organ/space SSI. Specific precautions to prevent organ/space and incisional SSIs may shorten hospital stays.

Role of gadoxetic acid-enhanced magnetic resonance imaging in the preoperative evaluation of small hepatic lesions in patients with colorectal cancer.
The initial abdominal computed tomography (CT) scans of patients with colorectal cancer (CRC) sometimes reveal equivocal hepatic lesions. In this study, we evaluated the outcomes of equivocal hepatic lesions found by abdominal CT and the diagnostic accuracy of subsequent liver magnetic resonance imaging (MRI). ⋯ Gadoxetic acid-enhanced MRI is a useful diagnostic tool for assessing equivocal hepatic lesions on preoperative CT of CRC patients that allows increased diagnostic accuracy and detection of additional colorectal liver metastasis lesions.

Long-term outcomes of open and video-assisted thoracoscopic lung lobectomy for the treatment of early stage non-small cell lung cancer are similar: a propensity-matched study.
Generally, in retrospective studies, favourable short- and long-term outcomes for patients after lung lobectomy for early stage non-small cell lung cancer (NSCLC) using video-assisted thoracoscopic surgery (VATS) have been reported. However, the interpretation of lung lobectomy outcomes may be biased in retrospective settings. ⋯ VATS lobectomy is less invasive than open lobectomy, but in terms of survival outcomes, VATS lobectomy was oncologically equivalent to open lobectomy. The oncological benefit of VATS reported by retrospective studies might be overestimated.
