PURPOSE: Although there are more than a hundred techniques, including the transabdominal and the perineal approaches, for the repair of the rectal prolapsed, none of them is perfect. The best repair should be chosen not only to correct the prolapse but also to restore defecatory function and to improve fecal incontinence throughout the patient's lifetime. The aim of this retrospective review is to evaluate clinical outcomes of the Delorme's procedure for the management of the complete rectal prolapse. METHODS: A total of 19 patients (13 females and 6 males) with complete rectal prolapses were treated by using the Delorme's procedure in St. Vincent's Hospital, The Catholic University of Korea, from February 1997 to February 2007. Postoperative anal incontinence was evaluated using the Cleveland Clinic Incontinence Score. RESULTS: All 19 patients had incontinence to liquid stool, solid stool, and/or flatus preoperatively. Three (15.8%) patients reported recurrence of the rectal prolapse (at 6, 18, 29 months, respectively, after the operation). Information on postoperative incontinence was available for 16 of the 19 patients. Twelve of the 16 patients (75%) reported improved continence (5 [31.3%] were improved and 7 [43.7%] completely recovered from incontinence) while 4 patients had unchanged incontinence symptoms. One (6.3%) patient who did not have constipation preoperatively developed constipation after the operation. CONCLUSION: The Delorme's procedure is associated with a marked improvement in anal continence, relatively low recurrence rates, and low incidence of postoperative constipation. This allows us to conclude that this procedure still has its own role in selected patients.

OBJECTIVE: Absence of dysplasia in the excised specimen following loop electrosurgical excision procedure (LEEP) for treatment of cervical intraepithelial neoplasia (CIN) 2/3 is an occasional finding of uncertain clinical significance. We evaluated several factors including age, liquid-based Pap (LBP) test, human papillomavirus (HPV) load before treatment, and HPV typing as predictors for absence of dysplasia. Absence of dysplasia in LEEP specimens was analyzed in terms of factors for recurrent disease after LEEP conization METHODS: In total, 192 women (mean age, 39.3+/-8.4 years; range, 24 to 70 years) with biopsy-proven CIN 2/3 were treated by LEEP conization. Age, LBP test, histological grade, HPV load, and HPV DNA typing were evaluated as possible predictors of the absence of residual dysplasia or recurrent disease. RESULTS: Of the LEEP specimens, 34 (17.7%) showed no dysplasia in preoperative biopsies from patients with proven CIN 2/3. Low HPV load (<100 relative light units [RLU]) was significantly related to the absence of dysplasia in LEEP specimens, using logistic regression. Margin involvement and high HPV load (> or =400 RLU) were significant factors for recurrence. CONCLUSION: Absence of dysplasia in LEEP specimens occurred in 17.7% of our specimens. Prediction of the absence of dysplasia in LEEP specimens was associated with low HPV load. Residual/recurrent disease after LEEP was associated with a positive resection margin and high viral load, and was not associated with absence of dysplasia in LEEP specimens. Even if there is no dysplasia in conization specimens, close follow-up for residual/recurrent disease is needed.

PURPOSE: Neonatal hydronephrosis is diagnosed with an incidence of 4.5-7% of pregnancies. Recently, early detection of neonatal hydroneprosis with antenatal ultrasonography has become possible. But consensus about its management has not been reached, especially concerning surgical intervention. The purpose of this study is to analyze the natural course of neonatal hydronephrosis and to determine the guideline of surgical intervention and follow up study. METHODS: Sixty nine hydronephrotic kidneys were confirmed from April 2001 to April 2005. All cases were rechecked by ultrasonography once at least and had a minimum follow-up of 6 months. We classified the patients into 4 groups according to the anterior posterior pelvic diameter(APPD) on perinatal ultrasonography. Ultrasonography to measure the APPD diameter and Society for Fetal Urology(SFU) grade, (99m)Tc-MAG3 scan were done to a set protocol. Pyeloplasty was performed according to the protocol. RESULTS: Pyeloplasty was not needed in most cases where the APPD was below 10 mm and where the SFU grade were less than grade 3. Many cases with APPD 10 mm above or SFU grade III above had undergone pyeloplasty. We found a correlation between obstruction grade on MAG3 scan and whether surgery was performed or not. CONCLUSION: If APPD is above 10 mm, SFU grade is above grade 3 or urinary tract obstruction is suspected by MAG3 scan, pyeloplasty must be considered. In cases where APPD is below 10mm and SFU grade is less than grade 3, we can observe the natural course of neonatal hydronephrosis with consecutive follow-up.

Background: The median nerve cross-sectional area (MNCSA) is a useful morphological parameter for the evaluation of carpal tunnel syndrome (CTS). However, there have been limited studies investigating the anatomical basis of median nerve flattening. Thus, to evaluate the connection between median nerve flattening and CTS, we carried out a measurement of the median nerve thickness (MNT). Methods: Both MNCSA and MNT measurement tools were collected from 20 patients with CTS, and from 20 control individuals who underwent carpal tunnel magnetic resonance imaging (CTMRI). We measured the MNCSA and MNT at the level of the hook of hamate on CTMRI. The MNCSA was measured on the transverse angled sections through the whole area. The MNT was measured based on the most compressed MNT. Results: The mean MNCSA was 9.01 ± 1.94 mm 2 in the control group and 6.58 ± 1.75 mm 2 in the CTS group. The mean MNT was 2.18 ± 0.39 mm in the control group and 1.43 ± 0.28 mm in the CTS group. Receiver operating characteristics curve analysis demonstrated that the optimal cut-off value for the MNCSA was 7.72 mm2 , with 75.0% sensitivity, 75.0% specificity, and an area under the curve (AUC) of 0.82 (95% confidence interval [CI], 0.69-0.95). The best cut off-threshold of the MNT was 1.76 mm, with 85% sensitivity, 85% specificity, and an AUC of 0.94 (95% CI, 0.87-1.00). Conclusions Even though both MNCSA and MNT were significantly associated with CTS, MNT was identified as a more suitable measurement parameter.

BACKGROUND: Although water chambers are often used as surrogate blood-warming devices to facilitate rapid warming of red blood cells (RBCs), these cells may be damaged if overheated. Moreover, filtered and irradiated RBCs may be damaged during the warming process, resulting in excessive hemolysis and extracellular potassium release. METHODS: Using hand-held syringes, each unit of irradiated and leukocyte-filtered RBCs was rapidly passed through a water chamber set to different temperatures (baseline before blood warming, 50℃, 60℃, and 70℃). The resulting plasma potassium and free hemoglobin levels were then measured. RESULTS: Warming RBCs to 60℃ and 70℃ induced significant increases in free hemoglobin (median [interquartile ranges] = 60.5 mg/dl [34.9-101.4] and 570.2 mg/dl [115.6-2289.7], respectively). Potassium levels after warming to 70℃ (31.4 ± 7.6 mEq/L) were significantly higher compared with baseline (29.7 ± 7.1 mEq/L; P = 0.029). Potassium levels were significantly correlated with storage duration after warming to 50℃ and 60℃ (r = 0.450 and P = 0.001; r = 0.351 and P = 0.015, respectively). CONCLUSIONS: Rapid warming of irradiated leukoreduced RBCs to 50℃ may not further increase the extracellular release of hemoglobin or potassium. However, irradiated leukoreduced RBCs that have been in storage for long periods of time and contain higher levels of potassium should be infused with caution.

BACKGROUND: In pediatric patients, dynamic preload indices to predict fluid responsiveness remain controversial. Because each beat of blood pressure (BP) - waveform - contains evidence of a systolic and diastolic time interval (STI, DTI), we compared pulse pressure variation (PPV) with respiratory STI and DTI variation (STV, DTV) as predictors of fluid responsiveness during pediatric liver transplantation. METHODS: A total of 61 datasets from 16 pediatric liver transplant patients (age range one month to seven years), before and after an inferior vena cava clamp was applied, were retrospectively evaluated from electronically archived BP and central venous pressure (CVP) waveforms. STI and DTI were separated by a beat-to-beat blood pressure waveform. STV, DTV and PPV were calculated by averaging three consecutive respiratory cycles. Averaged CVP was used as a static preload index. A PPV threshold of > or =16%, a known cutoff value in pediatric surgery, was used to discriminate fluid responsiveness in the receiver operating characteristic (ROC) curve analysis. RESULTS: PPV showed correlations with STV and DTV (r = 0.65 and 0.57, P < 0.001, respectively), but not with CVP (r = -0.30, P = 0.079). The area under the ROC curves (AUC) of STV, DTV and CVP were 0.834, 0.872, and 0.613, respectively. Cut-off values of STV and DTV were 7.7% (sensitivity/specificity, 0.80/0.83) and 7.7% (sensitivity/specificity, 0.70/0.88), respectively. CONCLUSIONS: This study demonstrates that STV and DTV from a BP waveform showed the potential to predict fluid responsiveness as a surrogate of PPV during pediatric surgery.

We report an extraordinary case in which the venous route for pulmonary artery catheterization was unusual. A 41 year-old woman with an end-stage liver disease underwent a living-donor liver transplantation. After induction of anesthesia, the pulmonary artery catheter was revealed to be advanced into the left brachiocephalic vein and then slipped into another vein that drains into the left brachiocephalic vein. In this case, we assumed that the catheter had most likely slipped into the left pericardiophrenic vein since the catheter follows the left heart border similarly to the route of this vein according to the chest X-ray. Patients with liver cirrhosis develop many collateral vessels and have enlarged veins due to portal hypertension, which makes this vascular route possible. We present this case for anesthesiologists to be aware of the possibilities of unusual venous route due to dilated collateral vessels especially in liver transplant patients.
