Hem-o-Lok clips (Weck Surgical Instruments, Teleflex Medical, Durham, NC, USA) are widely used in robot-assisted laparoscopic radical prostatectomy because of their easy application and secure clamping. To date, there have been some reports of intravesical migration of these clips causing urethral erosion, bladder neck contractures, and subsequent calculus formation. We report the first case of bladder migration of Hem-o-Lok clips without stone formation after robot-assisted laparoscopic radical prostatectomy. The Hem-o-Lok clips were found during urethral dilation with a guide wire for bladder neck contracture under cystourethroscopy. The Hem-o-Lok clips were floating in the bladder without stone formation and were removed by a cystoscopic procedure.

Background Although the use of postoperative opioids is a well-known risk factor for postoperative nausea and vomiting (PONV), few studies have been performed on the effects of intraoperative opioids on PONV. We examined the effects of a single bolus administration of fentanyl during anesthesia induction and the intraoperative infusion of remifentanil on PONV. Methods Two hundred and fifty women, aged 20 to 65 years and scheduled for thyroidectomy, were allocated to a control group (Group C), a single bolus administration of fentanyl 2 µg/kg during anesthesia induction (Group F), or 2 ng/ ml of effect-site concentration-controlled intraoperative infusion of remifentanil (Group R) groups. Anesthesia was maintained with sevoflurane and 50% N2O. The incidence and severity of PONV and use of rescue antiemetics were recorded at 2, 6, and 24 h postoperatively. Results Group F showed higher incidences of nausea (60/82, 73% vs. 38/77, 49%; P = 0.008), vomiting (40/82, 49% vs. 23/77 30%; P = 0.041) and the use of rescue antiemetics (47/82, 57% vs. 29/77, 38%; P = 0.044) compared with Group C at postoperative 24 h. However, there were no significant differences in the incidence of PONV between Groups C and R. The overall incidences of PONV for postoperative 24 h were 49%, 73%, and 59% in Groups C, F, and R, respectively (P = 0.008). Conclusions A single bolus administration of fentanyl 2 µg/kg during anesthesia induction increases the incidence of PONV, but intraoperative remifentanil infusion with 2 ng/ml effect-site concentration did not affect the incidence of PONV.

Background Caudal epidural injections have been commonly performed in patients with low back pain and radiculopathy. Although caudal injection has generally been accepted as a safe procedure, serious complications such as inadvertent intravascular injection and dural puncture can occur. The present prospective study was designed to investigate the influence of the depth of the inserted needle on the success rate of caudal epidural blocks. Methods A total of 49 adults scheduled to receive caudal epidural injections were randomly divided into 2 groups: Group 1 to receive the caudal injection through a conventional method, i.e., caudal injection after advancement of the needle 1 cm into the sacral canal (n = 25), and Group 2 to receive the injection through a new method, i.e., injection right after penetrating the sacrococcygeal ligament (n = 24). Ultrasound was used to identify the sacral hiatus and to achieve accurate needle placement according to the allocated groups. Contrast dyed fluoroscopy was obtained to evaluate the epidural spread of injected materials and to monitor the possible complications. Results The success rates of the caudal injections were 68.0% in Group 1 and 95.8% in Group 2 (P = 0.023). The incidences of intravascular injections were 24.0% in Group 1 and 0% in Group 2 (P = 0.022). No intrathecal injection was found in either of the two groups. Conclusions The new caudal epidural injection technique tested in this study is a reliable alternative, with a higher success rate and lower risk of accidental intravascular injection than the conventional technique.

Background The purpose of this study was to evaluate the effects of ketorolac on the incidence and severity of emergence agitation in children recovering from sevoflurane anesthesia. Methods Eighty-five children aged 3 to 7 years were randomly assigned to the control group or the ketorolac group (1 mg/kg ketorolac). The children were evaluated by the Pediatric Anesthesia Emergence Delirium Scale and a four-point agitation scale. Results The median agitation scores did not differ significantly between the two groups. The overall incidence of emergence agitation was similar in the two groups (41% in the control group vs. 32% in the ketorolac group, P = 0.526). The number of children who received rescue drugs for treatment of emergence agitation was not significantly different between the two groups. Conclusions The administration of 1 mg/kg of ketorolac is not effective in decreasing the incidence and severity of emergence agitation in children aged 3 to 7 years after sevoflurane anesthesia.

Hemangiolymphangioma is an extremely rare malformation of both the lymphatic and blood vessels. To date, however, there are no reports in the literature of a hemangiolymphangioma of the testis. An 84-year-old man visited our hospital for investigation of a 1-month episode of a rapidly growing mass in his right scrotum. Scrotal ultrasonography revealed a multilobulated mass with septation in the testis. Testicular tumor markers were within the normal limit. Radical orchiectomy was performed. At surgery, a red, wide-based, nodular tumor was found on the testis. Histological examination of the resected specimen showed it to be a cavernous hemangiolymphangioma. Here we report this first case of a cavernous hemangiolymphangioma of the testis without cutaneous hemangiomatosis in an elderly patient.

Pheochromocytoma is a rare catecholamine producing tumor. Anesthetic management for the resection of pheochromocytoma is hard and challenging issue to anesthesiologist, because of its potentially lethal cardiovascular complications. It becomes more complicated when the patient is pregnant. Clinicians must keep the safety of both mother and fetus in mind. The timing of surgery for pheochromocytoma in pregnancy is very important for the maternal and fetal safety and depends on the gestational age when diagnosis is made, clinical response to medical treatment, the surgical accessibility of the tumor, and the presence of fetal distress. We report anesthetic experience of a laparoscopic resection for pheochromocytoma in 25th week gestational woman.

Purpose To evaluate the direct anti-cancer effect of a single instillation of epirubicin (SIE) after transurethral resection of bladder tumor (TURBT) for non-muscle-invasive bladder cancer (NMIBC) by analysis of immediate urine cytology (IUC). Materials and Methods We reviewed the records of 158 patients who had IUC after TURBT for NMIBC. Fifty-six patients were treated with SIE after TURBT and 102 patients were not treated with SIE. The direct anti-cancer effect of SIE was compared in the two groups according to the result of IUC. The relationship between SIE and IUC in NMIBC was analyzed by use of multivariate Cox proportional hazards regression models. Results The IUC-positive rate was 33.9% in the SIE group and 42.1% in the non-SIE group (p=0.005). The IUC-positive rate was lower in the SIE group than in the non-SIE group for each factor, including tumor stage, tumor grade, tumor size, tumor multiplicity, and preoperative urine cytology. Multivariate Cox proportional hazards regression analysis revealed that SIE was significantly associated with a negative IUC result in patients with NMIBC (HR, 0.163) (p<0.001). Conclusions These results indicate the direct anti-cancer effect of SIE in patients who undergo TURBT for NMIBC.

Objective To evaluate the efficacy and safety of 0.75% ropivacaine instillation into inguinal wound in patients who have undergone bilateral microsurgical varicocelectomy. Patients and methods Eighty-five men who were screened for bilateral varicoceles from March 2015 to July 2016 were randomized for the treatment. All patients underwent inguinal varicocelectomy by general anesthesia. After ligation of the internal spermatic veins from the spermatic cord, additional delivery of testis through inguinal incision site was done to ligate external spermatic veins and gubernacular veins. Before repairing external oblique aponeurosis, 6 mL of 0.75% ropivacaine and 6 mL of normal saline were instilled under the fascia and around the funiculus (spermatic cord) by a randomized and double-blind method. Visual analog scale (VAS) pain score and Prince Henry Pain Score (PHPS) were used for evaluating operative sites at 1, 2, 4, and 8 hours and 7 days after surgery. Safety and tolerability were evaluated throughout the course of this study by assessing adverse events. Results A total of 55 men completed the study. Of these 55 men, 31 received instillation of ropivacaine on the left operative site, while 24 received instillation of ropivacaine on the right operative site. VAS pain scores and PHPS in the ropivacaine-instilled operative site were significantly lower compared to those obtained with placebo at 2, 4, and 8 hours after surgery. In general, instillation of ropivacaine was safe and well tolerated in patients. Conclusion Ropivacaine instillation into inguinal surgical site wound significantly reduced postoperative pain after microsurgical varicocelectomy.

ticle, which is one of the few reports about the safety of a mixture of bupivacaine in children who underwent urologic inguinal and scrotal surgery. In their study, patients were injected with a mixture of 0.5% bupivacaine and 2% lidocaine (2:1 volume ratio) at the surgical site, just before surgery ended [1]. Hemodynamic and electrocardiographic parameters were measured before local anesthesia, 30 minutes after the administration of local anesthesia, and 60 minutes after administration [1]. The results of their study indicate that no mixturerelated adverse events (nausea, vomiting, pruritus, sedation, or respiratory depression) or adverse events related to electrocardiographic parameters (arrhythmias or asystole) were reported in any patients [1]. The observation that even children did not experience side effects suggests that this mixture will be even safer in adults. In our previous study, we evaluated the efficacy and safety of 0.75% ropivacaine instillation into inguinal wounds in patients who underwent bilateral microsurgical varicocelectomy [2]. Before repairing the external oblique aponeurosis, 6 mL of 0.75% ropivacaine or 6 mL of normal saline was instilled under the fascia and around the funiculus (spermatic cord) in a randomized and double-blind study design. Visual analogue scale (VAS) pain scores and the Prince Henry Pain Score (PHPS) were used for evaluating the operative sites at 1, 2, 4, and 8 hours and 7 days after surgery [2]. The VAS pain scores and PHPS at the ropivacaineinstilled operative sites were significantly lower than those in the placebo group at 2, 4, and 8 hours after surgery [2]. In general, the instillation of ropivacaine was safe and well tolerated in patients [2]. Bupivacaine is a long-acting amide-based topical anesthetic that is commonly used in clinical practice [3], while ropivacaine is a new amino amide with a structure similar to that of bupivacaine. Bupivacaine and ropivacaine are long-acting local anesthetics. Bupivacaine and ropivacaine produce cutaneous vasoconstriction that restricts

Background Although the positive effects of preoperative oral carbohydrate administration on clinical outcomes followingmajor surgery have been reported continuously, there are few investigations of them in minor surgical patients. Thepresent study was designed to examine the effects of preoperative oral carbohydrate administration on patient well-beingand satisfaction in patients undergoing thyroidectomy. Methods Fifty adults aged 20–65 years and scheduled for elective thyroidectomy in first schedule in the morning wereallocated to one of two groups. The Control group (n = 25) was requested to obey traditional preoperative fasting aftermidnight prior to the day of surgery. The Carbohydrate group (n = 25) also fasted overnight but drank 400 ml of carbohydrate-richdrink 2 hours before induction of anesthesia. Patient well-being (thirst, hunger, mouth dryness, nauseaand vomiting, fatigue, anxiety and sleep quality) and satisfaction were assessed just before the operating room admission(preoperative) and 6 hours following surgery (postoperative). Other secondary outcomes including oral Schirmer’s testand plasma glucose concentrations were also evaluated. Results The two groups were homogenous in patient characteristics. Seven parameters representing patient well-beingevaluated on NRS (0–10) and patient satisfaction scored on a 5-point scale were not statistically different between thetwo groups preoperatively and postoperatively. There were no statistically significant differences in secondary outcomes. Conclusions Preoperative oral carbohydrate administration does not appear to improve patient well-being and satisfactioncompared with midnight fasting in patients undergoing thyroidectomy in first schedule in the morning.
