ABSTRACT

INTRODUCTION: Recently, the utilization of surgical stabilization of rib fractures (SSRF) with video-assisted thoracoscopic surgery (VATS) has been increasing owing to its effectiveness. The present report describes the case of a patient who underwent SSRF with VATS and subsequently developed a splenic rupture that was speculated to be related to intrathoracic manipulation during surgery. PRESENTATION OF CASE: A 62-year-old male patient sustained injuries from a fallen festival car over his thoracoabdominal zone and was diagnosed with bilateral multiple rib fractures and burst fractures of the twelfth thoracic and first lumbar vertebrae. The patient underwent SSRF with VATS. Following surgery, the patient went into hemorrhagic shock due to a splenic rupture, necessitating an emergency open splenectomy. DISCUSSION: Despite no initial detection of splenic injury on contrast-enhanced CT, it is possible that a slight splenic injury existed at the time of the initial diagnosis. Moreover, during surgery, additional external forces may have been applied to the spleen due to positional changes, such as shifting to the lateral position or retracting the diaphragm using forceps; these manipulations could have potentially caused a slight splenic injury, possibly leading to splenic rupture. CONCLUSION: When performing SSRF through VATS, it is important to recognize that manipulation and traction of the diaphragm could potentially cause splenic rupture, even if a slight force is applied. Therefore, the diaphragm should be evaluated without traction and manipulation whenever possible.

ABSTRACT

BACKGROUND: Pulmonary vein stump thrombosis may occur after left upper lobectomy (LUL) and is a potential risk factor for cerebral infarction. However, there are few reports on the role of pulmonary vein stump thrombosis in the development of cerebral infarction. We aimed to clarify the correlation between pulmonary vein stump thrombosis and cerebral infarction following LUL. METHODS: We evaluated 296 patients who underwent contrast-enhanced computed tomography (CT) after LUL for lung cancer at the Shizuoka Cancer Center Hospital in Shizuoka, Japan, between September 2002 and December 2015. The cerebral infarction in patients with pulmonary vein stump thrombosis was examined, and the risk factors for cerebral infarction were identified via a univariate analysis of the clinicopathological and surgical variables. RESULTS: Overall, 179 men and 117 women (median age: 68 years; range: 36-88 years) were included. The median observation period was 68 months. Pulmonary vein stump thrombosis occurred in 21 (7%) patients and cerebral infarction occurred in 15 (5%) patients. None of the 21 patients with pulmonary vein stump thrombosis developed cerebral infarction. Most cerebral infarctions (12/15) were diagnosed in the late phase (> 3 months). The pathological stage of cancer was found to be the only significant risk factor for cerebral infarction by the univariate analysis. CONCLUSION: Pulmonary vein stump thrombosis following LUL was not necessarily associated with cerebral infarction, including the late phase. A prospective observational study with contrast-enhanced chest CT would be required to investigate the risk factors for cerebral infarction in each phase of the postoperative period.

ABSTRACT

OBJECTIVES: Although pulmonary emphysema is a component of chronic obstructive pulmonary disease, the prognostic significance of the quantitative severity of emphysema in patients with primary lung cancer is unclear. This study aimed to identify the association between the quantitative severity of emphysema detected by the low-attenuation area on computed tomography and the prognostic outcome of early non-small-cell lung cancer. METHODS: A consecutive series of 1062 patients who underwent lobectomy for clinical stage I and II non-small-cell lung cancer were enrolled in this study. The clinicopathological features and long-term outcomes of patients with primary lung cancer in emphysema were investigated. The extent of emphysema in the lobe where the tumour was present was measured by preoperative computed tomography as a percentage of the low-attenuation area (LAA%). RESULTS: LAA% ≥ 1.0% was detected in 145 (13.7%) patients. LAA% was associated with pleural invasion (P < 0.0001), vascular invasion (P < 0.0001) and a larger tumour size (P = 0.001). The overall survival and recurrence-free survival in patients with LAA% ≥ 1.0% and with LAA% < 1.0% at 5 years were 78.6% and 92.1% (P < 0.0001) and 68.7% and 85.2% (P < 0.0001), respectively. According to the Cox proportional hazards model, LAA% was an independent prognostic factor for overall survival and recurrence-free survival (P = 0.0004 and P = 0.003, respectively). CONCLUSIONS: The quantitative severity of pulmonary emphysema was found to be associated with poor prognosis and clinicopathological aggression in early non-small-cell lung cancer.

ABSTRACT

BACKGROUND: Pulmonary resection with mediastinal lymph node dissection for treating primary lung cancer could sometimes causes chylothorax as a postoperative complication. This study examined the validity of treatments for chylothorax in our hospital. METHODS: We evaluated 2019 patients who underwent lobectomy, bilobectomy, or pneumonectomy with mediastinal lymph node dissection for primary lung cancer at Shizuoka Cancer Center Hospital, Shizuoka, Japan, between September 2002 and March 2018. The diagnostic criteria for postoperative chylothorax were that the drainage from the pleural drain was evidently white and turbid, or the pleural effusion contained a triglyceride level of > 110 mg/dL. The clinical courses and treatments were retrospectively reviewed. RESULTS: Postoperative chylothorax occurred in 37 patients (1.8%), 20 men and 17 women, with a median age of 70 years (33-80). A low-fat diet was instituted to all patients; 35 cases improved with conservative treatment, and 2 cases required reoperation. Nine cases had a drainage volume ≥ 500 mL one day following the low-fat diet commencement, which was resolved with conservative treatment and decreased drainage was observed on the third day of treatment in seven of those cases. Two cases with excessive drainage of ≥ 1000 mL in one day and systemic symptoms associated with chyle loss needed surgery. CONCLUSIONS: Even when the daily drainage volume exceeds 500 mL following a low-fat diet, there were many cases that could be cured conservatively. The indication for surgery needs to be carefully considered.

ABSTRACT

BACKGROUND: Positive preresection pleural lavage cytology (PLC+) is a poor prognostic factor in non-small cell lung cancer (NSCLC). This study evaluated the prognostic value of PLC+ for the different pathologic stages (p-stages) of NSCLC. METHODS: A retrospective analysis was conducted of all 1293 staged patients who underwent curative resection in the Shizuoka Cancer Center Hospital, Shizuoka, Japan, for NSCLC to evaluate the impact of PLC+ on survival, specifically in patients with p-stage I NSCLC. The survival rate between patients with and without PLC+ was compared using the Kaplan-Meier method with the log-rank test for comparison. RESULTS: PLC+ was identified in 50 of the 1293 patients (3.9%) and was correlated with lymph node metastasis (P < .001), a pathologic tumor size larger than 3 cm (P = .033), the presence of pleural invasion (P < .001), and adenocarcinoma (P = .038). In patients with PLC+, the 5-year disease-free survival (DFS) was 31.1%, compared with 75.7% for patients with a negative PLC (PLC-) (P < .001). On multivariate analysis, the PLC+ status was an independent prognostic factor of DFS (hazard ratio 1.70; P = .013). Among the 818 patients with p-stage I NSCLC, PLC+ was identified in 22, with a 5-year DFS of 40.4%. The prognosis in patients with p-stage I NSCLC with PLC+ was equal to that in patients with p-stage IIIA NSCLC with PLC- (5-year DFS, 40.4% and 39.0%). CONCLUSIONS: PLC is an independent prognostic factor in early-stage NSCLC. Therefore, it may be appropriate to up-stage an NSCLC diagnosis in the presence of PLC+, especially for patients with p stage I.

ABSTRACT

BACKGROUND: Postoperative respiratory complications are often severe and associated with a high risk of mortality in patients who undergo open abdomen (OA) management following emergency damage-control surgery. The causes of postoperative respiratory complications remain unknown. Therefore, we evaluated postoperative factors associated with respiratory complications in nontrauma patients who had undergone OA management using propensity score matching, with a focus on OA-related risk factors. METHODS: This retrospective analysis included subjects who underwent OA management during a 4-y study period. Age, body mass index, and smoking history were selected as covariates. After propensity score matching, we compared postoperative factors (ie, first operative time, duration of OA, initial 3-d fluid balance, length of ICU stay, and in-hospital mortality) in 2 groups of subjects: those who had post-OA respiratory complications (PORCs) and those who did not. RESULTS: 60 subjects (33 men and 27 women) were identified; 38.3% of these subjects had PORCs. After propensity score matching, 18 subjects were matched. The 3-d fluid balance was significantly higher in subjects with PORCs than in those without PORCs (3,513 mL vs 1,087 mL; P = .03). CONCLUSIONS: To our knowledge, this is the first study to examine factors associated with respiratory complications following OA in nontrauma subjects. After adjusting for known co-factors associated with postoperative respiratory complications, the 3-d fluid balance was identified as a significant risk factor for PORCs in subjects who had undergone OA. Clinicians should pay attention to the incidence of PORCs in OA subjects with a positive fluid balance after emergency abdominal surgery.

ABSTRACT

INTRODUCTION: Pelvic fractures can occur in minor injuries, such as falls, in the elderly. Extensive adhesion of preperitoneal space is common after pelvic fracture surgery; hence, surgical interventions for inguinal hernia may be challenging. We treated a case of inguinal hernia after pelvic fracture surgery, using novel laparoscopic methods: iliopubic tract repair (IPTR) and modified intraperitoneal onlay mesh (mIPOM) approach. PRESENTATION OF CASE: This is the case of an elderly male with pelvic fracture. Open reduction and internal fixation were performed. Eighteen months after the procedure, a right inguinal bulge appeared, swelling increased, and he opted for surgery. We chose laparoscopic surgery to determine the status of the hernia and anatomy around the pelvis. He was diagnosed with an indirect inguinal hernia, and the inner inguinal ring was widely open. We chose the mIPOM approach and IPTR. He was discharged on day 3 post-operation. He developed a seroma after surgery, which disappeared after a month. Six months post-operation, no recurrence or neurologic pain observed. DISCUSSION: The transabdominal preperitoneal approach (TAPP) was initiated at first; however, the adhesion inside the inferior epigastric vessels was very strong, challenging to break into the preperitoneal space. We switched to the mIPOM method because the peritoneum was fragile and difficult to suture. Additionally, the internal ring was widely opened; hence, we proceeded with IPTR on confirmation that no tension on the abdominal wall was applied. CONCLUSIONS: Laparoscopic surgery is useful in flexibility of surgical options, such as TAPP, IPTR, IPOM, in addition to hybrid conversion.

ABSTRACT

OBJECTIVES: In lung cancer resection, chronic obstructive pulmonary disease is a risk factor for post-operative complications. Few studies on post-operative complications of lung cancer resection have considered radiographic emphysematous change as an index. Here, we have examined the relationship between the regional ratio of the emphysematous area in pre-operative computed tomography images and cardiopulmonary complications in patients with chronic obstructive pulmonary disease who underwent lung cancer resection. METHODS: We retrospectively evaluated 159 patients with chronic obstructive pulmonary disease who underwent lobectomy for lung cancer at Shizuoka Cancer Center Hospital, Shizuoka, Japan, between 2002 and 2011. Pre-operative factors, including the proportion of the emphysematous area measured by computed tomography as a percentage of the low attenuation area (LAA%), as well as intraoperative factors were analyzed. Cardiopulmonary complications, including pyothorax, pneumonia and atelectasis, acute pulmonary injury, indwelling chest tube, long duration of oxygen supply, and arrhythmia, were evaluated. RESULTS: Cardiopulmonary complications were observed among 61 patients (38%). Univariate analysis revealed that patient age, percentage of forced expiratory volume in 1 s, LAA%, and volume of blood loss were significantly associated with cardiopulmonary complications. Multivariate analysis indicated patient age and LAA% as being significant independent predictors of cardiopulmonary complications. CONCLUSIONS: The regional ratio of the emphysematous area is useful for predicting cardiopulmonary complications in patients with chronic obstructive pulmonary disease who undergo lobectomy for lung cancer. In such patients who are also ≥ 70 years of age and exhibit LAA% ≥ 1.0%, careful intra- and post-operative management is warranted.

ABSTRACT

Recent advances in radiographic imaging and thoracic surgery have facilitated surgery for small lung tumors by eliminating the need for pathological diagnosis. To date, we have experienced two cases of small lung tumors that were surgically resected without pathological diagnosis as malignant. Computed tomography (CT) revealed sub-solid nodules in the peripheral lung. After tumor resection, both tumors were pathologically diagnosed as peribronchiolar metaplasia. To the best of our knowledge, solitary peribronchiolar metaplasia showing a sub-solid nodule on CT imaging has not previously been reported.

ABSTRACT

OBJECTIVES: The indication of limited resection for radiographically pure-solid, small-sized lung adenocarcinoma is controversial. This study aimed to reveal the long-term outcome of standard surgical treatment and determine the predictive factors for pathological lymph node metastasis in optimal candidates undergoing limited surgical resection for pure-solid, small-sized lung adenocarcinoma. METHODS: The medical records of 107 consecutive patients were retrospectively reviewed at our hospital between December 2002 and December 2013. Inclusion criteria were histopathological diagnosis of lung adenocarcinoma, radiographically pure-solid tumor, ≤ 2 cm tumor size measured using thin-section computed tomography, clinical N0M0, patients who underwent lobectomy with systematic or lobe-specific lymph node dissection, and R0 resection. Overall and disease-free survival curves were calculated using the Kaplan-Meier method. Clinicopathological factors predicting pathological node-positive metastasis were identified by univariate and multivariate analysis. RESULTS: The 5-year overall and disease-free survival rates were 91.4% and 87.3%, respectively. Multivariate analysis demonstrated maximum standardized uptake value > 5 as the independent predictor of pathological node-positive metastasis (odds ratio 3.81; 95% confidence interval 1.25-12.3; p = 0.02). In all patients, the pathological node-positive rate was 16.7%; in patients who had a maximum standardized uptake value of ≤ 5, the rate was 7.9%. CONCLUSION: The long-term outcome of standard surgical treatment was favorable. Maximum standardized uptake value was a significant predictor of pathological node-positive metastasis; however, diagnostic accuracy was not favorable. Therefore, the selection of optimal candidates is difficult, and limited surgical resection may not be applicable in pure-solid, small-sized lung adenocarcinoma.

ABSTRACT

We report a case of Masaoka stage IVb thymic carcinoma that had metastasized to right supraclavicular lymph nodes, where it would have been difficult to achieve complete resection. Thus, we performed concurrent chemoradiotherapy, which decreased the tumor's size and facilitated complete resection. The patient had an uneventful postoperative course and 30 months of recurrence-free survival. Concurrent chemoradiotherapy followed by complete surgical resection may be a useful strategy in cases of stage IVb thymic carcinoma with supraclavicular lymph node metastasis.

ABSTRACT

We retrospectively assessed the effectiveness and the safety of thoracic paravertebral block(PVB) in patients ineligible for epidural block (EP). Eleven PVB patients and 33 EP patients were enrolled. Postoperative pain was evaluated using a numerical rating scale (NRS). The mean NRS ± standard deviation at rest 24 and 48 hours after surgery were 1.36 ± 1.63 and 0.55 ± 1.03 in the PVB group and 1.07 ± 1.47 and 1.38 ± 1.31 in the EP group, respectively. There were no statistically significant differences in the NRS scores. Approximately 10% of the EP patients had complications such as hypotension, nausea and vomiting, or urinary retention. On the other hand, there were no adverse events in the PVB group. PVB can provide pain relief comparable to EP with a better side-effect profile. There were no technical complications associated with PVB. Thoracic PVB is an effective and safe method of postoperative analgesia for patients undergoing thoracic surgery with ineligibilities for EP.

ABSTRACT

Spontaneous rupture of the esophagus, which is also known as Boerhaave's syndrome, is a rare life-threatening condition that requires urgent surgical management. The optimal treatment involves surgical repair of the esophageal defect, which is usually accomplished via laparotomy, thoracotomy, or both, and mediastinal debridement. Here, we report a case of spontaneous rupture of the esophagus that was treated with suturing repair and drain insertion using a hand-assisted laparoscopic approach.

ABSTRACT

INTRODUCTION: During surgical resection of a peripherally located high-grade neuroendocrine carcinoma (HGNEC), we unexpectedly discovered prominent bronchial intraepithelial tumor spread up to the surgical end of the bronchus. Because bronchial intraepithelial tumor spread of peripherally located HGNEC has been rarely reported, we conducted a retrospective analysis at our hospital. METHODS: We histologically reviewed surgically resected HGNEC cases to assess bronchial intraepithelial spread of tumor cells. HGNECs with bronchial intraepithelial tumor spread were further studied by immunohistochemistry for neuroendocrine markers, and their clinicopathological characteristics were evaluated. RESULTS: Of 1778 cases of surgically resected lung cancer in our hospital, 47 cases of HGNEC were evaluated. Bronchial intraepithelial tumor spread was observed in nine cases (19.1%); eight of these cases were large-cell neuroendocrine carcinoma (LCNEC) or small-cell lung carcinoma with an LCNEC component. Moreover, bronchial intraepithelial tumor spread was continuous from the primary tumor to the resected end of the bronchus in four cases, and all these cases had an LCNEC component. Furthermore, HGNEC with bronchial intraepithelial tumor spread was associated with a higher recurrence rate than no bronchial intraepithelial tumor spread. CONCLUSION: The results of this study suggest that bronchial intraepithelial tumor spread is commonly observed in cases of peripherally located HGNEC and may be a unique form of tumor invasion, especially tumors with LCNEC morphology. Therefore, surgeons and pathologists should be cognizant of bronchial intraepithelial tumor spread in peripherally located HGNEC, as well as its potential role as an indicator of HGNEC aggressiveness.

ABSTRACT

A 37-year-old woman noticed a right anterior chest mass and pain. The mass had been rapidly growing and she visited our hospital. The mass was hard and 8 × 7 cm in size. It was detected in the upper inner quadrant of her anterior chest wall. A computed tomography (CT) examination and magnetic resonance imaging (MRI) of the chest revealed a large heterogeneously enhanced mass arising from the right chest wall with lytic destruction of the rib and coarse calcification. An image diagnosis of osteogenic sarcoma originating from a rib was made. She underwent surgical excision of the tumor and chest wall reconstruction. Microscopic examination of the resected tumor showed multiple neoplastic cells accompanied by osteoid formation within the tumor. The tumor was diagnosed as high-grade malignant osteosarcoma of the rib. Primary osteosarcoma commonly originates in the long bone in children and adolescents, but it occurs very rarely in the ribs in adults. Surgical resection plays an important role in the treatment for this disease. We report a case of primary osteosarcoma that originated in the rib of a young woman and was treated successfully by surgery.
