<i>Purpose</i>: Central venous catheters (CVCs) are used in the treatment of pediatric hematological and oncological diseases. Recently, the ultrasound (US)-guided supraclavicular approach to brachiocephalic vein cannulation with in-plane views has been described as a safe central venous catheterization technique.<i>Methods</i>: A retrospective study was performed on patients who underwent US-guided tunneled CVC insertion into the internal jugular vein with out-of-plane views (IJV group) and the brachiocephalic vein with in-plane views (BCV group). The patients’ background characteristics, surgical outcomes, and complications were compared retrospectively.<i>Results</i>: A total of 40 tunneled CVCs (IJV group: n = 15, BCV group: n = 25) were inserted in 34 patients. The patients’ background characteristics were not significantly different between the two groups. The operative times were 30 min (range: 27–33 min) in the IJV group and 25.8 min (range: 22–27 min) in the BCV group. The BCV group had a significantly shorter operative time (p = 0.0026). Intraoperative complications were observed in one patient (6.7%) in the IJV group and none of the patients in the BCV group. Complications during maintenance were observed in 10 patients (66.7%) in the IJV group and 17 patients (68%) in the BCV group. Catheter-related bloodstream infection was noted in 10 patients (66.7%) in the IJV group and 12 patients (52%) in the BCV group; these infection rates were not significantly different. The periods of CVC implantation were 273 days (172–363.5 days) in the IJV group and 152 days (101–280 days) in the BCV group, which were not significantly different.<i>Conclusions</i>: A real-time US-guided supraclavicular approach to brachiocephalic catheterization was considered a safe technique for pediatric patients with hematological and oncological diseases.

Background. Ultrasonography using Sonazoid, a novel contrast agent containing microbubbles, is a useful diagnostic modality for intrahepatic mass lesions with specific characteristics in two phases: contrast enhancement of early vascular perfusion and perfusion defect of the lesion in the late phase. To improve the diagnostic accuracy of intraoperative ultrasonography (IOUS) in biliary neoplasms, particularly gall bladder, we investigated the usefulness of the Sonazoid contrast agent in a preliminary study.
Subjects and Methods. We examined IOUS images of 23 patients with gall bladder disease. Sonazoid was administered intravenously, and early arterial and venous phase images of the tumor were obtained during laparotomy.
Results. Tumors included the localized type of adenomyomatosis in the fundus of the gallbladder (GAM) in seven patients as benign controls, adenomatous diseases in three, and gallbladder carcinoma (GC) in 13. Sonazoid IOUS scanning was performed in all patients, with no adverse effects. Although GC showed high enhancement in 77% of the tumors, GAM and adenoma also showed mild enhancement in more than half of them. Pseudo-positivity was observed in one case of hyperplastic polyps, and pseudo-negativity was observed in two patients. Cholesterol polyps and a suspicious lesion of liver metastasis by the computed tomography were not enhanced with Sonazoid treatment.
Conclusion. Although there remains a problem of pseud-positivity in the intracystic lesions, Sonazoid IOUS may be a useful tool to detect vascularity and its location or extension of gallbladder diseases; however, neither significance of differential diagnosis with benign diseases nor other clinical significance was found. -

We report a case of injury of the external iliac vein caused by a stab wound. A 55-year-old man presented with a piece of wood stuck in his right abdomen. Physical examination revealed that he was in a state of shock and he was urgently transferred to our emergency department. We suspected gastrointestinal perforation and right external iliac arteriovenous injury based on the findings of CT, and decided to perform emergency surgery. Intraoperative exploration revealed that a piece of wood had penetrated the small intestine and the right external iliac vein. We controlled bleeding by compression and repaired the veins. After the operation, right external iliac vein thrombosis was observed, which resolved with anticoagulant therapy. Traumatic iliac vein injury is relatively rare, but since it is often fatal, prompt and appropriate treatment is necessary.

A 73 y.o.-male underwent the arch aortic replacement for type A acute aortic dissection. Two years after operation, the computed tomography showed the rupture of thoracic aortic aneurysm and thoracic endovascular aortic repair （TEVAR） was urgently performed. Aorto-esophageal fistula （AEF） subsequently occurred at day 5 after TEVAR. Therefore, we urgently performed esophagectomy under right thoracotomy with accompanied fistulectomy, followed by omentopexy and esophageal reconstruction using gastric conduit 12 days later. To secure AEF patients, the immediate bleeding and infectious control is required. Although urgent artificial blood vessel replacement with esophagectomy with fistulectomy of AEF is desirable, the strategy of surgical intervention depends on the patient’s organ functions or systemic status. Omentopexy is an effective option to reinforce the postoperative infectious control and, additionally, the intraoperative ICG fluorescence angiography may improve to evaluate the omental vascularity by our experience.

Two cases of mixed neuroendocrine carcinoma and non-neuroendocrine neoplasm (MiNEN) are presented. A 50-year-old woman noticed an abdominal mass. Transverse colon cancer [cT3N2bM0 cStage IIIc] was diagnosed by computed tomography and colonoscopy. Right hemi-colectomy and lymphadenectomy were performed. Pathological examination showed combined features of adenocarcinoma and neuroendocrine carcinoma. The pathological diagnosis was MiNEN, pT3N0M0 pStage IIa. The patient received 8 courses of adjuvant CapeOX chemotherapy. At 12-month follow-up, the patient was well with no evidence of recurrence. A 72-year-old man was found to be positive for fecal occult blood. Colonoscopy showed a sigmoid colon polyp. The patient underwent endoscopic mucosal resection (EMR) of the polyp. The pathological diagnosis was MiNEN with deep submucosal (SM) invasion. Based on these findings, additional resection (laparoscopic sigmoidectomy and D3 lymph node dissection) was performed. The pathological diagnosis was MiNEN, pT1bN1M0 pStage IIIa. However, the patient did not wish to receive chemotherapy. At 60-month follow-up, the patient was well, with no evidence of recurrence. Although the prognosis of MiNEN is quite poor, multidisciplinary treatment resulted in a relatively good course. These cases are reported with a review of the literature.

The patient was a two-year-old girl who had been treated for recurrent vomiting for three days. She was brought to our hospital after her previous doctor suspected gastrointestinal perforation due to sudden abdominal distension. When she arrived at our hospital, her face was pale, her vitality was poor, and she had a peripheral cold sensation. Her pulse rate was 200/min, her blood pressure was 60/42 mmHg, her respiratory rate was 43/min, and she was in shock. Contrast-enhanced computed tomography (CT) of the abdomen showed a large amount of free air and ascites along with findings of gastric volvulus. Emergency laparoscopic surgery was performed. The gastric volvulus was corrected laparoscopically. Because the site of perforation was challenging to identify, we changed the procedure to open laparotomy. A pinhole perforation was found at the upper gastric corpus due to detachment of the omentum. Wedge-shaped resection was performed around the perforation, and the stomach was fixed to the abdominal wall. No migrating spleen was observed. The postoperative recovery from disseminated intravascular coagulation and improvement of gastric peristalsis took a few days, but she gradually improved. She was discharged on the 19th postoperative day. Since her discharge from the hospital, there has been no recurrence of volvulus. There have been several reports on gastric perforation associated with acute gastric volvulus. Since there have been some reports of death due to the rapid and severe onset of symptoms, a prompt diagnosis and treatment are required.

A 70-year-old man presented to our hospital with abdominal fullness. Severe stenosis of the sigmoid colon and a dilated colon were confirmed using abdominal computed tomography. The cause of the obstruction was unclear. Transverse colostomy was performed. Three months after the surgery, a colovesicocutaneous fistula formed. We considered colon cancer ; however, colonoscopy in our hospital showed several diverticula in the sigmoid colon and no malignancy. We diagnosed a colovesicocutaneous fistula secondary to sigmoid colon diverticulitis and performed high anterior resection and partial cystectomy with fistulotomy. The pathological diagnosis was diverticulosis, and there was no malignancy. We encountered a case of colovesicocutaneous fistula due to diverticulosis that required differentiation from cancer.
