We report the case of a 68-year-old man with a stromal tumor of uncertain malignant potential (STUMP), which had metastasized to the lung. The patient complained of an enlarged mass in the anterior chest. Chest computed tomography (CT) showed a sternal abscess with multiple nodules in both lungs. A thoracoscopic lung biopsy of the nodules and incision/drainage of the sternal mass were performed simultaneously. CT of the pelvis revealed an enlarged prostate with irregular cystic lesions in the pelvis. Prostate biopsy was done and demonstrated hypercellular stroma with minimal cytological atypia, a distinct pattern of STUMP. The sternal abscess proved to be tuberculosis and the lung lesion was consistent with STUMP, which had spread from the prostate. However, to our knowledge, the tuberculous abscess might not be assoicated with STUMP in the lung. The patient refused surgical prostatectomy and was discharged with anti-tuberculosis medication. On one-year follow up, the patient had no evidence of disease progression.

Background: Intraoperative monitoring during carotid endarterectomy is crucial for cerebral protection. We investigated the results of carotid endarterectomy under dual monitoring with stump pressure and electroencephalography. Methods: We retrospectively reviewed the medical records of 50 patients who underwent carotid endarterectomy between March 2010 and February 2016. We inserted a temporary shunt if the stump pressure was lower than 35 mm Hg or if any intraoperative change was observed on electroencephalography. Results: Seventeen (34%) patients used a temporary shunt, and the mean stump pressure was 26.8 mm Hg in the shunt group and 46.5 mm Hg in the non-shunt group. No postoperative mortality or bleeding occurred. Postoperatively, there were 3 cases (6%) of minor stroke, all of which took place in the shunt group. A comparison of the preoperative and the intraoperative characteristics of the shunt group with those of the non-shunt group revealed no statistically significant difference between the 2 groups (p<0.01). Conclusion: Dual monitoring with stump pressure and electroencephalography was found to be a safe and reliable monitoring method with results comparable to those obtained using single monitoring. Further study should be performed to investigate the precise role of each monitoring method.

Purpose: Duodenal stump leakage (DSL) is a potentially fatal complication that can occur after gastrectomy, but its underlying risk factors are unclear. This study aimed to investigate the risk factors and management of DSL after laparoscopic radical gastrectomy for gastric cancer (GC). Materials and Methods: Relevant data were collected from several prospective databases to retrospectively analyze the data of GC patients who underwent Billroth II (B-II) or Rouxen-Y (R-Y) reconstruction after laparoscopic gastrectomy from 2 institutions (Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, and HwaMei Hospital, University of Chinese Academy of Sciences). The DSL risk factors were analyzed using univariate and multivariate analysis regression. Results: A total of 810 patients were eligible for our analysis (426 with R-Y, 384 with B-II with Braun). Eleven patients had DSL (1.36%). Body mass index (BMI), elevated preoperative C-reactive protein (CRP) level, and unreinforced duodenal stump were the independent risk factors for DSL. DSL was diagnosed in 2-12 days, with a median of 8 days. Seven patients received conservative treatment, 3 patients received puncture treatment, and only 1 patient required reoperation. All patients recovered successfully after treatment. Conclusions: The risk factors of DSL were BMI ≥24 kg/㎡, elevated preoperative CRP level, and unreinforced duodenal stump. Nonsurgical treatments for DSL are preferred.

The neuroma is a tumor of nerve tissue that partially or completely severed through incomplete regeneration process. Neuromas that formed in the stump of a limb following amputation is a cause of the stump pain and can make intractable pain. The authors report a rare case of 36-year-old man with neuroma at stump, which has been recurred three times. This patient was treated with end-to-end neurorrhaphy after resecting neuroma. Follow-up at out-patient clinic showed satisfied result.

From August 1988 to August 1991 40 automatic staplers[four TA 30 Premium and 36 TA 55 Premium] were used to close the bronchial stump in 38 patients. There were 8 pneumonectomies, 5 bilobectomies, 23 lobectomies, 1 lobectomy and segmentectomy, and 1 segmentectomy due to various pulmonary diseases. Among 40 bronchial stumps, 15 stumps were covered with the pleural flaps for reinforcing the stump and remained 25 stumps left uncovered. The patients of the 2 groups were selected randomly regardless of disease entities. The duration of follow-up was from 1 month to 38 month-average 16 months, and there were no bronchopleural fistulas in all cases during the follow-up period. Especially in the uncovered bronchial stumps group, 3 preoperative sputum AFB[+] patients and 2 patients of stage IIIa lung cancer underwent pneumonectomy with ipsilateral radical lymph node dissection were included. So, surgical stapling is the safe method and is recommended in closing the bronchial stump in various pulmonary resections.

A 20-year-old man underwent a Tc-99m HMPAO labeled leukocyte scan for the evaluation of an infection at the stump of an AK amputation, which was conducted due to an open communicated fracture of the left lower leg. Blood-flow and blood-pool images demonstrated a pseudoaneurysm with a focus of intense activity medial to the stump, and centered within a large photopenic defect by surrounding hematoma. Delayed image obtained at 3 hours post-injection showed persistent intense and slight increased activity, Contrast angiography confirmed the presence of a pseudoaneurysm arising from a branch of the left superficial femoral artery.

Neuroma is formed by abnormal, incomplete nerve regeneration after nerve injury. A painful neuroma in the hand can be psychologically and physically disabling. The goal of treating painful neuroma is to relieve pain and to restore nerve function. A numerous treatment modality was reported for alleviating the problem. These treatments include crushing the neuroma, ligating it, burying in soft tissue, bone, and muscle, injecting it with alcohol, phenol, and steroid, capping it with silicone cuff. But, none of these methods has been uniformly successful, although each has its advocates. No one technique reliably prevents formation of a painful neuroma. However, the principles of treatment is resection of neuroma and proximal stump of the nerve is transposed to appropriate adjacent tissue. Our current technique was resection of neuroma with partial normal neural tissue, and then the nerve ending was transposed and sutured to the side of the proximal stump with 10-0 nylon, so end-to-side neurorrhaphy was made. The nerve ending had to be placed and fixed into the proximal nerve epineurium like as a figure of a loop. We believe this technique is another useful method for the treatment of painful neuroma.

A mass excision surrounding the bronchial stump was performed to exclude malignancy in a 42-year-old man who had undergone a right lower lobectomy for lung cancer. The mass was identified as a cicatricial fibroma. Cicatricial fibromatosis, which is desmoid fibromatosis that arises in a surgical scar, is a well-known clinical condition. It consists of histologically benign neoplasms. Their occurrence after thoracic surgery is extremely rare. Biopsy or excision of suspicious lesions is very important for diagnosis. R0 resection remains the principal outcome for intrathoracic desmoid fibromatosis. We report that a cicatricial fibromatosis in the subcarinal space was removed after suspicion of local recurrence at the bronchial stump follwing lobectomy for lung cancer.

Disseminated peritoneal leiomyomatosis (DPL) is a very rare benign disease, characterized by multiple solid subperitoneal or peritoneal smooth muscle nodules in abdominopelvic cavity and malignant transformation is extremely rare. Also, uterine smooth muscle tumors of unknown malignant potential (STUMP) is a rare tumor, which is regarded as subclassification in uterine smooth muscle tumors between benign and malignant criteria. Pathogenesis of DPL is uncertain, but increasing evidence of iatrogenic cause including laparoscopic myomectomy has been reported. We report a case of a 28-year-old female with previous history of laparoscopic myomectomy diagnosed with DPL with atypical feature and concurrent uterine STUMP using computed tomography (CT) and magnetic resonance imaging (MRI), as well as present a review of the literature.

Stability of cable yarding with self-propelled carriage was discussed by theoretical tension calculation and field test. To verify usefulness of theoretical stability evaluation of cable yarding operation, skyline tension and stump anchoring force were measured and compared with theoretical calculation. As results, we know that measured skyline tension was similar to theoretical calculated tension. From these results, overall stability of cable logging operation could be evaluate. The stump anchoring force correlated closely with the stump diameters. The inclination angles that the stumps show the maximum anchoring force were ranged 5-10 degrees. It was conclude that the stumps have lost the function as an anchor when the inclinations was so large that they could be observed.
