RESUMO
BACKGROUND: Effective education about endoscopic surgery (ES) is greatly needed for unskilled surgeons, especially at low-volume institutions, to maintain the safety of patients. We have tried to establish the remote educational system using videoconference system through the internet for education about ES to surgeons belonging to affiliate institutions. The aim of this manuscript was to report the potential to establish a comfortable remote educational system and to debate its advantages. METHODS: We established a local remote educational conference system by combining the use of a general web conferencing system and a synchronized remote video playback system with annotation function through a high-speed internet. RESULTS: During 2014-2019, we conducted 14 videoconferences to review and improve surgeons' skills in performing ES at affiliated institutions. At these conferences, while an uncut video of ES that had been performed at one of the affiliated institutions was shown, the surgical procedure was discussed frankly, and expert surgeons advised improvements. The annotation system is useful for easy, prompt recognition among the audience regarding anatomical structures and procedures that are difficult to explain verbally. CONCLUSIONS: This system is of low initial cost and offers easy participation and high-quality videos. It would therefore be a useful tool for regional ES education.

BACKGROUND/AIM: Additional primary malignancy (APM) risk is increasing with improved prognosis of cancer survivors. In order to clarify risk factors and patients susceptible to develop APMs, we investigated the clinical features, prognosis, and approaches for diagnosis and treatment in these patients. PATIENTS AND METHODS: Among 874 patients newly diagnosed with gastrointestinal tract (GIT) or hepato-biliary-pancreatic (HBP) cancers between 2011 and 2014, 124 with a synchronous and/or metachronous APM were identified. Patient characteristics, time interval between the malignancies, clue to detect APMs, treatment approaches, and prognosis were investigated. RESULTS: Patients with APMs were older and predominantly male. Half of the metachronous APMs were detected within 3 years after the first primary malignancy (PM). The main clue to detect synchronous and metachronous APMs was preoperative screening for current PM, and follow-up of prior PM, respectively. There was no significant difference in the overall survival between colon cancer patients with or without APMs. CONCLUSION: Multiple PMs were present in 14.2% of patients. Male and old age were identified to be risk factors for APM. Pre-operative screening and post-operative regular follow-ups are important for detecting synchronous or metachronous APMs.

Objective Endoscopic self-expandable metallic stent (SEMS) placement and gastrojejunostomy (GJY) are palliative treatments for malignant gastric outlet obstruction (GOO). The aim of the present study was to compare the palliative effects of these treatments and identify predictors of a poor oral intake after treatment. Methods and Patients In total, 65 patients with GOO at multiple centers in Saga, Japan, were evaluated. Thirty-eight patients underwent SEMS placement, and 27 underwent GJY from January 2010 to December 2016. The characteristics and outcomes of the two groups were compared to detect predictors of treatment failure. Results No significant differences in the technical success, clinical success, post-treatment total protein, hospital discharge, duration from eating disability to death, or post-treatment overall survival were present between the SEMS and GJY groups. More patients in the GJY group than in the SEMS group received chemotherapy (51.4% vs. 26.3%, respectively; p=0.042). The period from treatment to the first meal was longer in the GJY group than in the SEMS group (4.5 vs. 3.0 days, respectively; p=0.013). The present study did not identify any risk factors for failure of SEMS placement. Although the stent length tended to be associated with a poor prognosis, the correlation was not statistically significant (odds ratio: 0.60, 95% confidence interval: 0.36-1.01, p=0.053). Conclusion Patients with GOO started meals more promptly after SEMS than after GJY, but the clinical outcomes were not markedly different between the SEMS and GJY groups. These findings suggest that endoscopic uncovered SEMS placement might be a feasible palliative treatment for GOO.

This case involved a 76-year-old man. Total colonoscopy was performed as a second examination for colorectal cancer because of positive fecal occult blood results, revealing a neoplasm with ulceration in the sigmoid colon. We suspected type-3 colorectal cancer and performed a biopsy, but the biopsy diagnosis showed only an ulcer with active inflammation. Colonoscopic re-examination in a highly advanced medical institution revealed granulomatous inflammation of the sigmoid colon caused by a fish bone, and the fish bone was removed endoscopically. Granulomatous inflammation of the colon caused by a fish bone is very rare, but sometimes needs to be differentiated from cancer. Endoscopic therapy can also be an option, depending on abdominal findings and the penetration status of the fish bone into the large intestinal wall.

BACKGROUND: Most groin masses are first suspected to be groin hernias. More than 80% of bulging groin lesions are reportedly diagnosed as hernias by ultrasonography. Establishment of the correct diagnosis of hernia among all differential diagnoses is not easy. We herein describe a very rare case of groin eosinophilic funiculitis that presented as an irreducible groin hernia. CASE PRESENTATION: A 59-year-old man presented to our hospital with suspicion of a right groin hernia. He had a 1-week history of a painful right groin tumor. The tumor was about 4 cm without skin redness or warmth, irreducible even in the supine position, and associated with mild tenderness. Enhanced computed tomography showed that the mass seemed to be connected to the intra-abdominal structures. With time, the patient's pain did not increase, the inflammatory response did not worsen, and no ischemic signs were observed by enhanced computed tomography. Therefore, we diagnosed the tumor as an irreducible but not incarcerated hernia and performed elective surgery. Intraoperative examination revealed no hernia sac, and a 4-×3-cm tumor was observed around the spermatic cord. A malignant tumor was not completely ruled out. High orchiectomy was performed after consultation with the urologists. Pathological examination of the tumor showed no malignant features, and the final diagnosis was eosinophilic funiculitis with massive inflammatory changes and eosinophil invasion. CONCLUSION: Eosinophilic funiculitis is very rare; only three cases have been reported to date. We should always consider unusual causes of groin masses during a surgical approach to hernia-like lesions.
RESUMO
Complete video-assisted thoracoscopic surgery (c-VATS) for lung cancer is minimally invasive because of the small incision required. c-VATS has recently become a standard procedure for treatment of stage IA/IB lung cancer. However, a long thoracic incision or extensive costal rib resection is required in patients with large lung tumors. We herein introduce an improved VATS lobectomy procedure for patients with T2 and T3 lung cancer. In this technique, resected tissue is removed through a small upper abdominal midline incision below the xiphoid through the retrosternal-extraperitoneal pathway. Five patients who underwent this new procedure were compared against 10 control patients who underwent hybrid VATS lobectomy. Significantly fewer patients who underwent c-VATS lobectomy complained of severe postoperative pain; however, there was no significant difference in the postoperative hospital stay between the two groups. The present study demonstrates that c-VATS lobectomy can be performed with minimal operative pain and without need for a long thoracic incision or extensive rib resection, even in patients with large lung tumors (T2 and T3). These results suggest that the indications for c-VATS lobectomy in patients with T2 and T3 non-small cell lung cancer can be expanded by implementation of our approach, which involves removal of the freed lobe through an abdominal incision.

An elastofibroma is a benign and rare fibrous lesion that most commonly occurs in the periscapular region. A gastrointestinal elastofibroma is extremely rare. In the present study, six cases of elastofibromas including a case in the stomach were evaluated. The gastric case revealed widely distributed lesions in the submucosal layer with perivascular fibrotic lesions (PVFLs) and some PVFLs were distributed to the skip lesions of elastofibroma. These PVFLs were also observed in all five periscapular cases and invariably contained elastic fibers which showed various degree of maturation. CD34-positive stromal cells were observed not only in elastofibromas but also in PVFLs in each case. These findings suggested the possibility of the PVFLs were the primary lesions of elastofibroma and their vascular-centric development. The percentage of the CD105-positive vessels in elastofibroma group was significantly higher than in the control group. This result indicates active neovascularization in elastofibromas.

A 68-year-old man underwent subtotal esophagectomy with two fields lymphadenectomy and postoperative chemotherapy so called low dose FP therapy for advanced esophageal cancer (Stage IIIa, pT 3, pN 1, M 0) in October 1999. As he was diagnosed with a recurrence of esophageal cancer as metastatic lymph node tumors which were placed in the right anterocervical and supraclavicular region in March 2001, he underwent enucleation of metastatic lymph node tumors and postoperative chemoradiation therapy, so-called low-dose FP-R therapy. Recently, since other metastatic lymph node tumors in the neck appeared again in August 2001, he underwent radical neck lymph node dissection and postoperative chemoradiation treatment, so-called FAP-R therapy. In October 2003, a chest CT showed multiple lung tumors. He was diagnosed with multiple metastatic lung tumors originating from esophageal cancer. Then, two courses of a combined chemotherapy consisting of TS-1 and CDDP were administered at an interval of one month. We judged the effect of this chemotherapy to be a partial response (PR), because the largest metastatic lung tumor 18 mm in diameter showed a reduction rate of 81.9%, and other tumors had almost disappeared in the chest CT after the combined therapy. No severe adverse effects of more than grade 3 were observed during this combined therapy. This combined chemotherapy consisting of TS-1 and CDDP may prove effective for treating recurrent cases of esophageal cancer.
