ObjectiveTo investigate the clinical application value of laparoscopic anatomical resection of liver segment 8 via a hepatic parenchymal transection-first approach guided by the middle hepatic vein.MethodsClinical data of 8 patients who underwent laparoscopic anatomical resection of liver segment 8 via a hepatic parenchymal transection-first approach guided by the middle hepatic vein in Xinqiao Hospital from May 2017 to December 2019 were retrospectively analyzed. The operation time, intraoperative blood loss, postoperative complications, and hospitalization duration were observed.ResultsAll patients were confirmed by pathology, the postoperative pathological results showed that: hepatocellular carcinoma was found in 6 patients, mixed hepatocellular carcinoma and cholangiocarcinoma was found in 2 patients. All patients completed the operation successfully without conversion to open surgery. The median operation time was 220 min (190-240 min), median blood loss was 230 mL (200-280 mL), and blood transfusion was not needed. The postoperative median hospital stay was 8 d (7–12 d). All the patients recovered well without severe complications. Eight patients were followed up for 10.5 to 31.7 months, with a median follow-up time of 16.9 months. During the follow-up period, none of them developed hemorrhage, bile leakage, and other complications. There was no reoperation or perioperative mortality during the follow-up.ConclusionsThe method of laparoscopic anatomical resection of liver segment 8 via a hepatic parenchymal transection-first approach guided by the middle hepatic vein is safe and effective. This method can shorten the operation time, improve the safety, and reduce the difficulty of operation.
ObjectiveTo explore the clinical value and experience of enhanced recovery after surgery (ERAS) of “LEER” model with “less pain” “early move” “early eat” and “reassuring” as its ultimate goal in perioperative period of laparoscopic anatomical hepatectomy of patients with primary liver cancer.MethodsThe basic clinical data of 98 patients treated in our department from May 2017 to March 2020 who were diagnosed as primary liver cancer and underwent laparoscopic anatomical hepatectomy were retrospectively analyzed. The incidence of postoperative complications, postoperative recovery and patients’ satisfaction were compared between 40 patients managed with traditional model (traditional group) and 58 patients managed with measures of ERAS of “LEER” model (“LEER”-ERAS group).ResultsCompared with the traditional group, the “LEER”-ERAS group had lower postoperative pain scores (t=2.925, P=0.004), earlier postoperative anal exhaustion, bowel movement and normal diet (t=3.071, t=3.770, t=3.232, all P<0.005) , shorter time to postoperative off-bed activity (t=5.025, P<0.001) and earlier postoperative removal time of drainage tube (t=3.232, P=0.001). Postoperative hospital stay was shorter (t=4.831, P<0.001), the cost of hospitalization was lower (t=3.062, P=0.003), and the patient’s satisfaction with medical treatment was higher (χ2=9.267, P=0.002). There were no statistical difference in the operative time, intraoperative blood loss, rate of conversion to laparotomy, blocking time of porta hepatis, postoperative complications and postoperative adverse events between the two groups (P>0.05).ConclusionsCompared with the traditional model, the measures of ERAS of “LEER” model that applied to laparoscopic anatomical hepatectomy of patients with primary liver cancer, is safe and effective, and can relieve postoperative pain, accelerate postoperative rehabilitation, improve satisfaction of patients, shorten hospital stay, and reduce medical costs. It has further promotion and research value.
ObjectiveTo investigate the clinical value of three-dimensional reconstruction of liver and resection of hepatocellular carcinoma with indocyanine green (ICG) fluorescence staining. MethodsClinical data of a patient with hepatocellular carcinoma admitted to the Department of Liver Surgery of West China Hospital of Sichuan University in May 2021 were retrospectively collected. In this patient, intrahepatic vascular reconstruction was performed by SYNAPSE 3D software of Japan before operation, and the portal vein and hepatic vein corresponding to the tumor were analyzed to simulate the resection range. Intraoperative ICG fluorescence staining was used to perform laparoscopic resection of segment Ⅳ of the liver.ResultsIn this patient, the fluorescence boundary on the liver surface was clear after staining, and the intrahepatic segment fluorescence interface could still be maintained in the hepatic parenchyma dissociation, and the resection of the liver segment was consistent with the preoperative three-dimensional reconstruction plan. The operation took 230 min in total, and the bleeding was about 200 mL. On the first day after the operation, blood biochemical test showed that the plasma albumin was slightly low, and no obvious abnormalities were observed in transaminase, bilirubin, etc. After the infusion of human albumin, the indexes returned to normal, and the patient recovered and was discharged on the fourth day after the operation. No complications occurred after the operation, and no tumor recurrence and metastasis were observed during follow-up period. Conclusion3D reconstruction and ICG fluorescence guidance are safe and feasible for the treatment of hepatocellular carcinoma after laparoscopic anatomic segment Ⅳ resection, and the positive staining method of ICG fluorescence segment is recommended.
ObjectiveTo explore the curative effect of precise hepatectomy techniques in hepatolithus. MethodsTotally 132 patients underwent precise hepatectomy and 52 patients underwent irregular hepatectomy were retrospectively analyzed, and the intraoperative and postoperative indexes such as operation time, blood loss, postoperative complications, hospitalization time, clearance rate of calculus, and cost of hospitalization were analyzed. ResultsCompared with the patients in irregular hepatectomy group, although the operative time was longer in precise hepatectomy group 〔(364.6±57.8) min vs. (292.9±44.7) min, Plt;0.001〕, but the patients in precise hepatectomy group had less blood loss 〔(558.3±90.6) ml vs. (726.7±88.7) ml, Plt;0.001〕, less postoperative complications (11.4% vs. 23.1%，P=0.004 3), and higher clearance rate of calculus (89.4% vs. 73.1%, P=0.005 5). Thus, the patients in precise hepatectomy group had shorter hospital stay 〔(22.9±4.4) d vs. (28.8±3.5) d, Plt;0.001〕 and less cost of hospitalization 〔(1.8±0.7)×104 yuan vs. (2.1±0.9)×104 yuan, P=0.016 5〕. Conclusion Precise hepatectomy is better than irregular hepatectomy in treatment for hepatolithus.
Abstract： The principles of 2010 National Comprehensive Cancer Network（NCCN） clinical practice guidelines in non-small cell lung cancer address that anatomic pulmonary resection is preferred for the majority of patients with non-small cell lung cancer and video-assisted thoracic surgery (VATS) is a reasonable and acceptable approach for patients with no anatomic or surgical contraindications. By reviewing the literatures on general treatment, pulmonary segmentectomy, pulmonary function reserve, and the anatomic issue of early stage non-small cell lung cancer surgery, the feasibility and reliability of thoracoscopic pulmonary segmentectomy are showed.
ObjectiveTo explore the safety and short-term efficacy of uniportal and three-port video-assisted thoracoscopic surgery (VATS) anatomical segmentectomy for pulmonary nodules. MethodsThe clinical data of 225 patients with consecutive VATS anatomic segmentectomy by the same surgeon in Xuzhou Central Hospital between December 2019 and February 2022 was retrospectively reviewed. There were 85 males and 140 females with an average age of 57.3±11.6 years. These patients were divided into an uniportal VATS group (128 patients) and a three-port VATS group (97 patients) according to the surgical procedures. Single-direction anatomical procedure was utilized in the uniportal VATS group. The operation time, blood loss during the surgery, number of dissected lymph nodes, duration and volume of chest drainage, incidence of complications, and postoperative hospital stay of the two groups were compared. ResultsThere was no conversion to thoracotomy, addition of surgical ports, or mortality in this cohort, with tumor-negative surgical margins. The postoperative pathological staining confirmed 2 (0.9%) patients of lymph node metastasis (pN1) and 4 (1.8%) patients of adenocarcinoma with micropapillary component. As compared with the three-port VATS group, patients in the uniportal VATS group had shorter operation time (115.6±54.7 min vs. 141.5±62.8 min, P=0.001), less intraoperative blood loss (77.2±49.6 mL vs. 96.9±98.1 mL, P=0.050), less total thoracic drainage [394.0 (258.8, 580.0) mL vs. 530.0 (335.0, 817.5) mL, P=0.010], and shorter postoperative hospital stay (7.7±3.7 d vs. 8.7±3.5 d, P=0.031). Both groups showed similar stations and numbers of dissected lymph nodes, incidence of operation-related complications, duration of chest tube drainage, and the drainage volume in the first and second postoperative days (P>0.05). No tumor recurrence or metastasis was recorded in this cohort during the follow-up of 11 (1-26) months. ConclusionSingle-direction uniportal VATS anatomical segmentectomy is safe and feasible for the treatment of pulmonary nodules, with better short-term efficacy as compared with the three-port VATS procedure, including shorter operation time, less intraoperative blood loss and thoracic drainage. However, further studies are needed to elucidate the precise indications of segmentectomy for lung cancer.
Objective To evaluate the feasibility and safety of complete video-assisted thoracoscopic surgery （VATS）anatomic segmentectomy. Methods Clinical data of 26 patients with lung diseases who underwent complete VATS anatomic segmentectomy in the First Affiliated Hospital of Nanjing Medical University from November 2010 to July 2011 were retrospectively analyzed. There were 8 male and 18 female patients with their age of 13-81 （53.2±3.1） years. There were 23 patients with pulmonary nodules including 13 patients who underwent direct surgical resection and 10 patients with ground-glass opacity nodules （3 patients received preoperative localization and the other 7 patients received direct surgical resection）. All the 3 patients with non-nodule pulmonary diseases （bronchiectasis, pulmonary bulla and pulmonary cyst respectively） underwent direct surgical resection. Results All the 26 patients received complete VATS anatomic segme- ntectomy successfully. The operation time was 150-250 （193.7±7.3） min，and intraoperative blood loss was 10-200 （65.7±12.7） ml. Patients with lung cancer received 4-7 （5.1±0.3） stations of lymph node dissection and the number of lymph node dissection was 4-16 （12.3±0.5） for each patient. There was no in-hospital death or postoperative complication. Postoperative thoracic drainage time was 3-7 （3.9±0.4） days. All the patients were discharge uneventfully. Lung cancer patients were followed up for 3-6 months without recurrence or metastasis. Conclusion Complete VATS anatomic segmentectomy is a safe and feasible surgical procedure.
Objective To assess the safety and clinical outcomes of segmentectomy in one- or two-staged video-assisted thoracoscopic surgery (VATS) for bilateral lung cancer. MethodsWe retrospectively enrolled 100 patients who underwent VATS segmentectomy for bilateral lung cancer at the Department of Thoracic Surgery of Peking Union Medical College Hospital from December 2013 to May 2022. We divided the patients into two groups: a one-stage group (52 patients), including 17 males and 35 females with a mean age of 55.17±11.09 years, and a two-stage group (48 patients), including 16 males and 32 females with a mean age of 59.88±11.48 years. We analyzed multiple intraoperative variables and postoperative outcomes. Results All 100 patients successfully completed bilateral VATS, and at least unilateral lung received anatomical segmentectomy. Patients in the one-stage group were younger (P=0.040), had lower rate of comorbidities (P=0.030), were less likely to have a family history of lung cancer (P=0.018), and had a shorter interval between diagnosis and surgery (P=0.000) compared with patients in the two-stage group. Wedge resection on the opposite side was more common in the one-stage group (P=0.000), while lobectomy was more common in the two-stage group. The time to emerge from anesthesia in the one-stage group was longer than that in the first and second operations of the two-stage group (P=0.000, P=0.002). Duration of surgery and anesthesia were similar between two groups (P>0.05). Total number of lymph node stations for sampling and dissection (P=0.041) and lymph nodes involved (P=0.026) were less in the one-stage group. Intraoperative airway management was similar between two groups (P>0.05). The one-stage group was associated with lower activities of daily living (ADL) scores. Conclusion Segmentectomy is safe in one- or two-staged VATS for bilateral lung cancer, including contralateral sublobectomy and lobectomy. Duration of surgery and perioperative complications are similar between two groups, but the one-stage group is associated with lower ADL scores. On the basis of comprehensive consideration in psychological factors, physical conditions and personal wishes of patients, one-staged sequential bilateral VATS can be the first choice.
Lung cancer, as one of the malignant tumors with the fastest increasing morbidity and mortality in the world, has a serious impact on people's health. With the continuous advancement of medical technology, more and more medical methods are applied to lung cancer screening, which has gradually increased the detection rate of early lung cancer. At present, the standard operation for the treatment of early non-small cell lung cancer (NSCLC) is still lobectomy and mediastinal lymph node dissection. There is a growing trend to use segmentectomy for the treatment of early stage lung cancer. Anatomical segmentectomy not only removes the lesions to the maximum extent, but also preserves the lung function to the greatest extent, and its advantages are also obvious. This article reviews the progress of anatomical segmentectomy in the treatment of early NSCLC.
