Utilization of End-of-Life Care Rooms by Patients Who Died in a Single Hospice Unit at a National University Hospital in South Korea / 한국호스피스완화의료학회지

Purpose@#For the dignity of patients nearing the end of their lives, it is essential to provide end-of-life (EoL) care in a separate, dedicated space. This study investigated the utilization of specialized rooms for dying patients within a hospice unit. @*Methods@#This retrospective study examined patients who died in a single hospice unit between January 1, 2017, and December 31, 2021. Utilizing medical records, we analyzed the circumstances surrounding death, the employment of specialized rooms for terminally ill patients, and the characteristics of those who received EoL care in a shared room. @*Results@#During the 1,825-day survey period, deaths occurred on 632 days, and 799 patients died. Of these patients, 496 (62.1%) received EoL care in a dedicated room. The average duration of using this dedicated space was 1.08 days. Meanwhile, 188 patients (23.5%) died in a shared room. Logistic regression analysis revealed that a longer stay in the hospice unit was associated with a lower risk of receiving EoL care in a shared room (odds ratio [OR]=0.98, 95% confidence interval [CI] 0.97~0.99; P=0.002). Furthermore, a higher number of deaths on the day a patient died was associated with a greater risk of receiving EoL care in a shared room (OR=1.66, 95% CI 1.33~2.08; P＜0.001). @*Conclusion@#To ensure that more patients receive EoL care for an adequate duration in a private setting, additional research is necessary to increase the number of dedicated rooms and incorporate them into the hospice unit at an early stage.

Association between Sleep Duration and Presbycusis in Korean Adults: Korea National Health and Nutrition Examination Survey / 가정의학회지

Background@#Sleep duration is associated with hearing loss, especially presbycusis, which is the most common type of hearing loss; however, there is limited evidence regarding this association among the Korean population. We aimed to determine the relationship between sleep duration and high-frequency hearing loss in Korean adults aged ≥40 years. @*Methods@#We examined 5,547 Korean adults aged ≥40 years who completed audiometric tests and questionnaires regarding sleep duration during the 2010–2012 cycle of the Korea National Health and Nutrition Examination Survey. Mild presbycusis was defined as >25 decibels (dB) and 40 dB pure tone averages at high frequencies (3,000, 4,000, and 6,000 Hz) for both ears. Additionally, the sleep duration was divided into quartiles. Odds ratios and 95% confidence intervals were estimated using multivariable logistic regression after adjusting for covariates. @*Results@#The prevalence of presbycusis in South Korean adults was 62.1%, of which 61.4% showed moderate to severe presbycusis. The incidence of moderate-to-severe, but not mild, presbycusis showed a significant positive correlation with sleep duration. @*Conclusion@#Our findings suggest that sleep duration is associated with the prevalence of presbycusis.

Unfavorable effect of high postoperative fluid balance on outcome of pancreaticoduodenectomy

Purpose@#Despite the many efforts to overcome postoperative complications, pancreaticoduodenectomy (PD) is still accompanied with considerable concerns of lethal complications. The clinical factors are known to affect postoperative outcomes such as diameter of pancreatic duct, texture of pancreas, and comorbidity of the patients are mostly uncorrectable. Thus, investigation for correctable risk factors is required. Recently, perioperative fluid volume was reported to be associated with complications after PD. This study aims to determine the relationship between postoperative fluid balance and surgical outcome after open PD. @*Methods@#We reviewed, retrospectively, 172 consecutive patients who underwent open PD in a single institution between 2015 and 2019. The status of perioperative fluid balance 2 days after surgery and clinical factors were investigated to determine the association with postoperative outcome including postoperative pancreatic fistula (POPF). According to postoperative fluid balance, patients were divided into high- and low-balance groups, and clinical features and surgical outcomes were compared between both groups. Multivariate analysis were performed to identify risk factors for POPF. @*Results@#The percentage of morbidity and the incidence of POPF were higher in the high-balance group compared to the low-balance group (61.6% vs. 37.2%, P = 0.001; 15.1% vs. 3.5%, P = 0.009). High postoperative fluid balance and the presence cardiovascular disease were correlated with POPF on multivariate analysis (odds ratio [OR], 4.574; 95% confidence interval [CI], 1.229–17.029; P = 0.023 and OR, 3.517; 95% CI, 1.209–12.017; P = 0.045). @*Conclusion@#Higher amount of postoperative fluid balance and the presence of cardiovascular disease are associated with POPF after PD.

Various types of reconstruction after pancreaticoduodenectomy for the patients who underwent all types of gastrectomy: a single-center experience

Purpose@#The incidence of patients requiring pancreaticoduodenectomy (PD) following any type of gastrectomy is increasing as the population of elderly patients is increasing, especially in endemic areas of gastric cancer such as Korea. All types of gastrectomy can be categorized as subtotal gastrectomy with Billroth I (BI), Billroth II (BII), and total gastrectomy with Roux-en-Y anastomosis. In this paper, we reviewed our experiences of PD for patients who previously underwent gastrectomy. @*Methods@#We reviewed the medical records of the patients who underwent PD following any type of gastrectomy among 505 consecutive patients who underwent PD in a single institution between 2011 and 2020 retrospectively. @*Results@#There were 13 patients who had undergone gastrectomy including 7 patients of BI, 1 patient of BII, and 5 patients of total gastrectomy. For all 7 patients of BI, the reconstruction was not different from conventional PD. For the 1 patient of BII, previous gastrojejunal anastomosis was preserved and reconstruction was performed in Roux-en-Y method. For the 5 patients with total gastrectomy, 2 different types of reconstruction were performed. In one patient, we removed the remaining jejunum with the specimen, and reconstruction was performed. For the other 4 patients, the remaining jejunum, distal to the Treitz ligament, was preserved and was utilized for anastomosis. Surgeries for all patients were uneventful. @*Conclusion@#PD following any type of gastrectomy can be safe. Especially, if the length of remained jejunum is long enough, its utilization for the reconstruction can be an appropriate option.

Surgery-first approach reduces the overall treatment time without damaging longterm stability in the skeletal class III correction: a preliminary study / 대한악안면성형재건외과학회지

Background@#Compared to the conventional approach, including preoperative orthodontic preparation, the socalled surgery-first approach (SFA) seems to reduce the overall treatment time in the correction of skeletal class III dentofacial deformity. However, there have been controversies about postoperative skeletal stability with SFA.Therefore, we investigated the long-term stability and the overall treatment time after maxillomandibular surgery for skeletal class III correction with or without preoperative orthodontic preparation. @*Methods@#This retrospective study included eight patients who underwent maxillomandibular surgery for class III correction with the SFA (SFA group) and 20 patients who underwent the conventional approach (CA group). A comparative study of the change in the maxillary and mandibular position on preoperative (T1), 1-day (T2), 6-month (T3), and 2-year (T4) postoperative lateral cephalograms. We calculated the overall treatment time for each group. @*Results@#At the presurgical stage (T1), there was no bias in the skeletal features between the two groups. In the surgical change from T1 to T2, the mandible (point B) of the CA group was significantly moved superiorly. Short-term changes from T2 to T3 revealed that the mandible moved forward in both groups, whereas the maxillary position showed no significant changes. Long-term changes from T3 to T4 demonstrated that none of the measured parameters showed any significant differences. Finally, the average of overall treatment time was 15.1 months in the SFA group and 26.0 months in the CA group. @*Conclusions@#These findings suggest that SFA in bimaxillary orthognathic surgery for skeletal class III correction leads to predictable long-term skeletal stability, similar to surgery with CA. Furthermore, SFA reduced the overall treatment time compared to CA.

Effect of Pressure Based Customized 3-Dimensional Printing Insole in Pediatric Flexible Flat Foot Patients / 대한족부족관절학회지

Purpose@#A flatfoot that fails to form a longitudinal foot arch is a common lower limb deformity in children. This study evaluated the structural and functional effects of the insole for pediatric flexible flat foot (PFFF). @*Materials and Methods@#Twenty-nine PFFF patients (20 boys and 9 girls, 58 feet) with bilateral symptomatic flatfoot deformities between February 2017 and May 2019 were included in this study. Sixteen patients (32 cases, study group) were treated with a pressured based 3-dimensional printing insole, and 13 patients (26 cases, control group) were followed up regularly without any treatment. Flatfoot was diagnosed by a lateral talo-first metatarsal angle of more than 4° in convex downward and talocalcaneal angles of more than 30° and a calcaneal pitch of less than 20°. The foot pressures, including the midfoot pressure, total foot pressure, and the ratio of the midfoot pressure to the total foot pressure, were evaluated by pedobarography. The clinical scores were assessed using the visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS), and Pediatrics Outcomes Data Collection Instrument (PODCI) scores. @*Results@#The mean age of the study group was 9.16 years, and the mean age of the control group was 7.73 years. The mean follow-up period was 16 months. The change in the lateral talocalcaneal angle was –4.664°±1.239° in the study group and –0.484°±1.513° in the control group. A significant difference in the amount of change of the lateral talocalcaneal angle was observed between the two groups (p=0.034). The midfoot pressures were similar in the two groups. @*Conclusion@#Pressure based customized 3-dimensional printing insole in PFFF may have some effect on the hindfoot bony alignment, but it does not affect the changes in midfoot pressure.

Species Distribution and Antifungal Susceptibility of Yeasts Isolated from Ear Specimens / 대한임상미생물학회지

BACKGROUND: Candida auris was first isolated from the ears of Japanese and Korean patients. However, the prevalence of yeast isolates from ear cultures and their antifungal susceptibility profiles in these nations remain unclear.METHODS: We assessed yeast isolates recovered from ear cultures from a university hospital in Korea over a 4-year period from January 2014 to December 2017. Species identification was performed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and/or sequence analysis. Antifungal minimal inhibitory concentrations (MICs) were determined using the broth microdilution method of the Clinical and Laboratory Standards Institute.RESULTS: Among 81 non-duplicate isolates from ear cultures, Cadida parapsilosis was the most frequently detected yeast species (34.6%), followed by C. auris (28.4%), Candida metapsilosis (9.9%), Candida orthopsilosis (8.6%), Candida albicans (7.4%), and others (11.1%). The MICs of the isolates were 0.125 to > 64 µg/mL, ≤0.03 to 4 µg/mL, 0.25 to 1 µg/mL, 0.125 to 1 µg/mL, and ≤0.03 to 2 µg/mL for fluconazole, voriconazole, amphotericin B, caspofungin, and micafungin, respectively. Of the 81 isolates, 44.4% (36/81) showed decreased susceptibility to fluconazole (MIC ≥4 µg/mL). Of the 23 C. auris isolates, 19 (82.6%) had a fluconazole MIC of ≥32 µg/mL. None of the isolates showed resistance to amphotericin B or echinocandins. Most of these patients suffered from chronic otitis media (84%).CONCLUSION: Candida parapsilosis complex and C. auris were the yeast species identified most frequently from ear cultures and they exhibited a high rate of fluconazole non-susceptibility, particularly C. auris.

A Case of Concurrent Ampullary Adenoma and Gangliocytic Paraganglioma at the Minor Papilla Treated with Endoscopic Resection

A gangliocytic paraganglioma is a benign tumor of the digestive system with a very low incidence. The tumor is histopathologically characterized by a triphasic pattern consisting of epithelioid, ganglion, and spindle-shaped Schwann cells. In most cases, it occurs in the second portion of the duodenum near the ampulla of Vater. We report a case of a gangliocytic paraganglioma occurring at the minor duodenal papilla (a rare location) with a concurrent adenoma of the ampulla of Vater. Both lesions were treated simultaneously using endoscopic resection. Additionally, we have presented a literature review.

Pheochromocytoma with Hypertensive Crisis Caused by Endoscopic Ultrasound-guided Tissue Sampling / 대한췌담도학회지

Although pheochromocytoma usually presents as a solid tumor, it can also present as a cystic lesion in the adrenal glands. Cystic lesions in the adrenal glands, along with hypertension, need attention to exclude pheochromocytoma. If ignored, they may lead to a hypertensive crisis with multi-organ failure. Proper preoperative preparation is important to prevent a hypertensive crisis during and after surgery. We report a case of pheochromocytoma with cystic degeneration that presented as a hypertensive crisis caused by endoscopic ultrasound-guided tissue sampling.

Impacts of Financial Coverage on Long-Term Outcome of Intensive Care Unit Survivors in South Korea

PURPOSE: The objective of this study was to investigate whether financial coverage by the national insurance system for patients with lower economic conditions can improve their 1-year mortality after intensive care unit (ICU) discharge. MATERIALS AND METHODS: This study, conducted in a single tertiary hospital, used a retrospective cohort design to investigate discharged ICU survivors between January 2012 and December 2016. ICU survivors were classified into two groups according to the National Health Insurance (NHI) system in Korea: medical aid program (MAP) group, including people who have difficulty paying their insurance premium or receive medical aid from the government due to a poor economic status; and NHI group consisting of people who receive government subsidy for approximately 2/3 of their medical expenses. RESULTS: After propensity score (PS) matching, a total of 2495 ICU survivors (1859 in NHI group and 636 in MAP group) were included in the analysis. Stratified Cox regression analysis of PS-matched cohorts showed that 1-year mortality was 1.31-fold higher in MAP group than in NHI group (hazard ratio: 1.31, 95% confidence interval, 1.06 to 1.61; p=0.012). According to Kaplan-Meir estimation, MAP group also showed significantly poorer survival probability than NHI group after PS matching (p=0.011). CONCLUSION: This study showed that 1-year mortality was higher in ICU survivors with low economic status, even if financial coverage was provided by the government. Our result suggests the necessity of a more nuanced and multifaceted approach to policy for ICU survivors with low economic status.

A rare case of miliary tuberculosis accompanying perihepatitis

Perihepatic capsulitis is associated with various diseases, such as Fitz-Hugh-Curtis syndrome, systemic lupus erythematosus, perforated cholecystitis, perforated hepatic abscess, and tuberculous peritonitis. Miliary tuberculosis is present in about 2% of all reported cases of tuberculosis and is characterized by the widespread millet-like hematogenous dissemination of Mycobacterium tuberculosis. We describe a 24-year-old virgin patient presenting with right upper quadrant and costovertebral angle pain. Diffuse perihepatic capsular enhancement was observed in abdominal computed tomography scans. Chest radiography showed miliary tuberculosis, and a polymerase chain reaction hybridization assay of sputum revealed the presence of M. tuberculosis. Symptoms improved after administering anti-tuberculosis medications. This report describes a rare case of miliary tuberculosis accompanying perihepatitis.

Reliable Radiologic Parameters to Predict Surgical Management for Clubfoot Treated with the Ponseti Method / 대한정형외과학회잡지

PURPOSE: Several radiologic reference lines have been used to evaluate individuals with a clubfoot but there is no consensus as to which is most reliable. The aim of this study was to identify which radiologic parameters have relevance to the predictability of additional surgery after Ponseti casting on clubfoot and the effect of clubfoot treatments that contain Ponseti casting and additional surgery. MATERIALS AND METHODS: A total of 102 clubfeet (65 patients, 37 bilateral) were reviewed from 2005 to 2013. The patients were divided into two groups (Group A, those for whom the result of the Ponseti method was successful and did not require additional surgery; and Group B, those for whom the result of the Ponseti method was unsuccessful and required additional surgery), and the following parameters were measured on the plain radiographs: i) talo-calcaneal angle on the anteroposterior and lateral view, ii) talo-1st metatarsal angle on the anteroposterior view, and iii) Tibio-calcaneal angle on the lateral view with the ankle full-dorsiflexion state. Each radiograph was reviewed on two separate occasions by one orthopedic doctor to characterize the intra-observer reliability, and the averages were analyzed. Next, 20 cases were chosen using a random number table, and two orthopedic doctors measured the angle separately to characterize the inter-observer reliability. RESULTS: Groups A and B included 73 clubfeet (71.6%) and 29 clubfeet (28.4%), respectively. The initial talo-calcaneal angle and tibio-calcaneal angle in the lateral view were significantly different among the groups. In addition, inter- and intra-observer biases were not detected. The talo-1st metatarsal angle on the anteroposterior view and tibio-calcaneal angle on the lateral view were significantly different after treatment in both groups. CONCLUSION: Congenital clubfeet treated with the Ponseti method showed successful results in more than 70% of patients. The initial talo-calcaneal angle and tibio-calcaneal angle on the lateral view were the radiologic parameters that could predict the need for additional surgical treatments. The talo-1st metatarsal angle on the anteroposterior view and tibio-calcaneal angle on the lateral view could effectively evaluate the changes in clubfoot after treatment.

Analytical Performance and Reference Interval of a Microfluidic Viscometer, Viscore-300 for the Measurement of Whole Blood Viscosity

BACKGROUND: Whole blood viscosity (WBV) refers to the internal resistance that occurs when blood flows through blood vessels. WBV is known to be related to many diseases including cardiovascular and neurovascular diseases. We have investigated the analytical performance and established reference intervals for a newly developed microfluidic viscometer, Viscore-300 (NanoBiz, Korea), used for the measurement of WBV. METHODS: We performed a precision test of 240 measurements over 20 days using three control materials. For evaluation of repeatability, a total of 60 WBV measurements were made in 3 whole blood samples 20 times a day. A total of 100 whole blood samples were used to evaluate the accuracy of the Viscore-300 in comparison to a rotating viscometer, DV3T (Brookfield, USA), in accordance with the the Clinical and Laboratory Standards Institute's guidelines. To establish the reference intervals, 122 healthy individuals were enrolled in this study. RESULTS: The precision and repeatability results showed that the CV was less than 5% for three samples and two shear rates. In the accuracy test, the mean differences between two viscometers were 0.09 cP (0.9%) and −0.07 cP (−1.4%) at shear rates of 10 s−1 and 300 s−1, respectively. The reference intervals of WBV for men were 6.88–13.52 cP at 10 s−1 and 4.32–6.43 cP at 300 s−1; those of women were 5.74–13.29 cP at 10 s−1 and 3.60–6.12 cP at 300 s−1. CONCLUSIONS: Viscore-300 showed excellent precision and accuracy and it might be a good instrument for reporting WBV quickly and accurately.

Internal Quality Assurance Status of Stool Examination as Assessed by a Questionnaire in Korean Clinical Laboratories

This study aimed to survey the status of quality control (QC) assurance for stool examinations at clinical laboratories in Korea. We sent a questionnaire related to QC practices in stool examination by electronic mail to Korean clinical laboratories that performed stool examination. Overall, 20 of the 39 laboratories (51.3%) reported performing stool concentration methods, and 28 (71.8%) examined the slides using only saline. A large proportion (74.4%) of respondents did not check the internal QC because of the restriction of appropriate control materials. Only four laboratories (10.3%) checked the reactivity of the dye solution routinely. For appropriate external QC systems, QC slides (43.6%) were preferred, followed by QC materials (30.8%), virtual slides (17.9%), and a combination of the above options (7.7%). The most commonly observed parasites in stool samples at the clinical laboratories were Clonorchis sinensis (75%), followed by Endolimax nana, Enterobius vermicularis, and Entamoeba coli. The present study describes the difficulties in internal QC assessment due to the absence of standardized QC materials and systems. We hope the findings of this report will provide a foundation for a QC assessment program for stool examinations in the near future.

Calcium pyrophosphate dihydrate deposition disease in the temporomandibular joint: diagnosis and treatment / 대한악안면성형재건외과학회지

BACKGROUND: Calcium pyrophosphate dihydrate deposition disease (CPDD) is a rare disease in the temporomandibular joint (TMJ) space. It forms a calcified crystal mass and induces a limitation of joint movement. CASE PRESENTATION: The calcified mass in our case was occupied in the left TMJ area and extended to the infratemporal and middle cranial fossa. For a complete excision of this mass, we performed a vertical ramus osteotomy and resected the mass around the mandibular condyle. The calcified mass in the infratemporal fossa was carefully excised, and the segmented mandible was anatomically repositioned. Scanning electronic microscopy (SEM)/energy-dispersive X-ray spectroscopy (EDS) microanalysis was performed to evaluate the calcified mass. The result of SEM/EDS showed that the crystal mass was completely composed of calcium pyrophosphate dihydrate. This result strongly suggested that the calcified mass was CPDD in the TMJ area. CONCLUSIONS: CPDD in the TMJ is a rare disease and is difficult to differentially diagnose from other neoplasms. A histological examination and quantitative microanalysis are required to confirm the diagnosis. In our patient, CPDD in the TMJ was successfully removed via the extracorporeal approach. SEM/EDS microanalysis was used for the differential diagnosis.

Prevalence of Osteoporosis and Effectiveness of Screening Test Using Ultrasound Bone Densitometry and Education in a Community-Dwelling Population

This prospective intervention study was undertaken to estimate the prevalence and treatment rate of osteoporosis following osteoporosis screening tests in the same cohort. From November 1, 2014 to August 31, 2015, participants received screening tests for osteoporosis using ultrasound bone densitometry and education concerning osteoporosis and related conditions. The participants were interviewed using a questionnaire on the diagnosis and initiation of osteoporosis treatment during the follow-up period. Of 960 potential participants, 595 people (68.8%; 150 men and 445 women) were given bone densitometry measurements and completed the questionnaire. The mean age of the participants was 74.0 years. Of the 595 participants, 393 people (66.1%; 67 men and 326 woman) were diagnosed with osteoporosis (T score <−2.5). The prevalence of osteoporosis showed an increasing trend, from 48.1% in 2004 to 66.1% in 2015. Of the 393 participants diagnosed with osteoporosis, 65 participants received additional bone densitometry measurements while hospitalized and osteoporosis management was re-initiated in 44 patients. The osteoporosis management rate in the study cohort increased from 21.6% to 32.8%, with osteoporosis diagnosed in 66.2% of participants at the latest follow-up. This prospective intervention study demonstrated that a screening test and an educational brochure increased the treatment rate from 21.6% to 32.8%.

A comparison between ketorolac and nefopam as adjuvant analgesics for postoperative patient-controlled analgesia: a randomized, double-blind, prospective study / 대한마취과학회지

BACKGROUND: We compared the analgesic efficacy and side effects of ketorolac and nefopam that were co-administered with fentanyl via intravenous patient-controlled analgesia. METHODS: One hundred and sixty patients scheduled for laparoscopic cholecystectomy were randomly assigned to ketorolac (Group K) or nefopam (Group N) groups. The anesthetic regimen was standardized for all patients. The analgesic solution contained fentanyl 600 µg and ketorolac 180 mg in Group K, and fentanyl 600 µg and nefopam 120 mg in Group N. The total volume of analgesic solution was 120 ml. Postoperative analgesic consumption, recovery of pulmonary function, and pain intensities at rest and during the forced expiration were evaluated at postoperative 2, 6, 24, and 48 h. The postoperative side effects of analgesics were recorded. RESULTS: Cumulative postoperative analgesic consumptions at postoperative 48 h were comparable (Group K: 93.4 ± 24.0 ml vs. Group N: 92.9 ± 26.1 ml, P = 0.906) between the groups. Pain scores at rest and during deep breathing were similar at the time of each examination. The recovery of pulmonary function showed no significant differences between the groups. Overall, postoperative nausea and vomiting incidence was higher in Group N compared with Group K (59% vs. 34%, P = 0.015). The other side effects were comparable between both groups. CONCLUSIONS: Analgesic efficacies of ketorolac and nefopam that were co-administered with fentanyl for postoperative pain management as adjuvant analgesics were similar. However, postoperative nausea and vomiting incidence was higher in the nefopam-fentanyl combination compared with the ketorolac-fentanyl combination.

The economic evaluation of nitrous oxide in sevoflurane anesthesia

BACKGROUND: Nitrous oxide (N2O) is much cheaper than recently introduced volatile anesthetics such as sevoflurane and desflurane, and can reduce the consumption of these anesthetics. The use of N₂O is under current debate. The purpose of this study was to evaluate economic effect of 50% N₂O during sevoflurane anesthesia in Korea. METHODS: Seventy patients were randomly allocated to Group A or Group N. Anesthesia induction was performed using propofol, rocuronium, and 3–5% of sevoflurane with air (Group A) or 50% N2O (Group N). Fresh gas flow (FGF) was 6 L/min during induction, and 3 L/min for maintenance. Mean arterial pressure (MAP), heart rate (HR), bispectral index (BIS), and minimum alveolar concentration (MAC) were recorded. The consumption of sevoflurane was measured at every 10 minutes for the first 1 hour. The economic effect was analyzed based on the payment criterion of Korean National Health Insurance Service. RESULTS: MAP, HR, BIS, and MAC showed no differences between the two groups. The sevoflurane consumptions for the first 1 hour were 39.2 ± 6.3 ml in Group A and 29.2 ± 4.9 ml in Group N (P < 0.01); and the N₂O consumption was 93.7 ± 1.5 L in Group N. The total costs of inhaled anesthetics were 16,190 (14.8 USD) and 13,062 (12.0 USD) Korean won for the first 1 hour in Groups A and N, respectively. CONCLUSIONS: Use of 50% N₂O with 3 L/min FGF reduced the sevoflurane consumption by 25% and anesthetic cost by 20% for the first 1 hour.

Effect of end-to-side inverted mattress pancreaticojejunostomy following central pancreatectomy on the prevention of pancreatic fistula

PURPOSE: Central pancreatectomy (CP) may be indicated for the treatment of benign or low-grade malignant tumor in the neck and proximal body of the pancreas. Pancreatic fistula is one of the most common complications after CP. In this study, we suggested an inverted mattress pancreaticojejunostomy (IM-PJ) technique to decrease the risk of pancreatic fistula. METHODS: Between 2010 and 2015, CP was performed with IM-PJ for 10 consecutive patients with a benign or low-grade malignant tumor in the neck and proximal body of the pancreas. All clinical and pathological data were analyzed retrospectively. RESULTS: Median age was 56.4 years (range, 17–75 years). Median surgery duration was 286 minutes (range, 205–410 minutes). In all cases, the distal stump was reconstructed using the IM-PJ method. Median duration of hospital stay was 23.8 days (range, 9–53 days). No patient mortality occurred. Pancreatic fistula developed in 9 cases (90%); however, all fistulas were grade A and resolved without surgical or radiological intervention. Nine patients remain well with no recurrence or new endocrine or exocrine dysfunction. CONCLUSION: Our results demonstrate that the outcomes of CP with IM-PJ are reasonable for prevention of pancreatic fistula following CP.
