Purpose:
Delayed gastric emptying usually manifests as gastric food retention. This study aimed to evaluate the incidence of gastric food retention after distal gastrectomy with gastrojejunostomy in gastric cancer patients and identify the risk factors for its development.
Materials and Methods:
We retrospectively enrolled 245 patients who underwent distal gastrectomy with gastrojejunostomy for gastric cancer at Boramae Medical Center between March 2017 and December 2019. We analyzed the presence of gastric food residue via computed tomography (CT) scans at 3 and 12 months postoperatively and analyzed the risk factors that may influence the development of gastric food retention.
Results:
CT scans were performed on 235 patients at 3 months and on 217 patients at 12 months postoperatively. In the group that received closure of Petersen's space, the incidence of gastric food retention was significantly low as per the 3- and 12-month postoperative follow-up CT scans (P=0.028 and 0.003, respectively). In addition, hypertension was related to gastric food retention as per the 12-month postoperative follow-up CT scans (P=0.011). No other factors were related to the development of gastric food retention. In the multivariate analysis, non-closure of Petersen's space (hazard ratio [HR], 2.54; 95% confidence interval [CI], 1.20–5.38; P=0.010) was the only significant risk factor for gastric food retention at 3 months postoperatively, while non-closure of Petersen's space (HR, 2.81; 95% CI, 1.40-5.64;P=0.004) and hypertension (HR, 2.30; 95% CI, 1.14–4.63; P=0.020) were both significant risk factors for gastric food retention at 12 months postoperatively.
Conclusions
Closure of Petersen's space has an effect on decrease the incidence of gastric food retention after distal gastrectomy with gastrojejunostomy in gastric cancer patients.

Purpose:
Gastrectomy for elderly patients can significantly deteriorate the health-related quality of life (HRQoL). There was no report comparing HRQoL of elderly patients with young patients after gastrectomy for gastric cancer. This study assessed the differences in the changes of HRQoL at one year after gastrectomy according to age.
Methods:
From May 2014 to Feb 2016, we prospectively enrolled patients undergoing gastrectomy for gastric cancer. They completed the European Organization for Research and Treatment of Cancer and gastric questionnaires preoperatively and at postoperative 1, 3, 6, 9, and 12 months.
Results:
We included 57 elderly patients (≥70 years old) and 74 younger patients. The elderly had similar demographic, surgical, and pathological characteristics with young patients except that elderly had more comorbidity, laparoscopic gastrectomies, and lesser postoperative chemotherapy. One month after gastrectomy, the score of global health status/ quality of life, physical, role, and social functioning were significantly impaired in elderly patients. Among them, physical and role functioning were more impaired than those of young patients. The scores of physical functioning, role functioning, cognitive functioning, and social functioning were not fully recovered till 1 year after surgery. There was a significant age group difference in the changes in physical function over the 1-year follow-up.
Conclusion
Elderly patients’ global health status/quality of life and social functioning significantly decreased at postoperative 1 month and recovered by 6 months after gastrectomy. There was a significant age-specific difference in physical functioning throughout the 1-year follow-up. Surgeons need to pay more attention to recovery of the elderly patients’ HRQoL after gastrectomy.

PURPOSE: To evaluate the prognostic factors that predict visual outcome after vitrectomy for lamellar macular hole using optical coherence tomography (OCT). METHODS: This study included 26 eyes that underwent pars plana vitrectomy, epiretinal membrane removal, and internal limiting membrane peeling for lamellar macular hole. The maximum parafoveal thickness, maximum height and diameter of lamellar macular hole, maximum height and diameter of intraretinal splitting, thinnest foveal floor thickness, and inner segment/outer segment disruption length on preoperative OCT image were investigated for prognostic factors that predict visual outcome. RESULTS: The mean follow-up period was 32.2 months and the mean best corrected visual acuity improved significantly after vitrectomy from log MAR 0.47 +/- 0.32 to log MAR 0.23 +/- 0.23. The postoperative visual acuity correlated significantly with preoperative visual acuity, thinnest foveal floor thickness and inner segment/outer segment disruption length, but not with maximum parafoveal thickness, maximum height and diameter of lamellar macular hole and maximum height and diameter of intraretinal splitting. CONCLUSIONS: The thinnest foveal floor thickness and inner segment/outer segment disruption length on preoperative OCT image were significant prognostic factors.

Purpose:
Many studies have demonstrated that single-incision or reduced-port laparoscopic distal gastrectomy is a feasible method compared to conventional laparoscopic distal gastrectomy. Using rigid-type laparoscope and right-side approach, we could perform dual-port laparoscopic distal gastrectomy (DPLDG) for gastric cancer. This study aimed to compare the surgical outcomes of DPLDG to those of 3-port laparoscopic distal gastrectomy (TPLDG).
Methods:
From March 2017 to December 2019, this retrospective study included 218 patients with gastric cancer who underwent DPLDG (106 patients) or TPLDG (112 patients) at SMG-SNU Boramae Medical Center. Surgical outcomes were compared between 2 operation methods.
Results:
Operation time was similar between DPLDG and TPLDG (158.9 ± 33.4 minutes vs. 154.0 ± 31.1 min, P = 0.787). The number of retrieved lymph nodes was similar between the 2 groups (35.3 ± 14.6 vs. 37.0 ± 13.5, P = 0.415). The complication rate in DPLDG and TPLDG groups was 10.4% and 8.9%, respectively (P = 0.894). The time to first flatus, time to first diet, and postoperative hospital stay were similar between the 2 groups. There were no reoperation or mortality cases. The cost of trocars was 359.9 US dollars (USD) in DPLDG and 291–391.4 USD in TPLDG.
Conclusion
The surgical outcomes of DPLDG and TPLDG did not differ. Regarding fewer incisions, DPLDG can be an alternative option for TPLDG.

Although adenosine (Ado) is being recently recognized as a potent inducer of apoptosis, molecular mechanism of apoptosis by Ado remains to be elucidated. In this study we observed that c-Myc was rapidly down-regulated in the apoptosis in human promyelocytic leukemia HL-60 cells treated with Ado. To establish the molecular and biochemical mechanisms of apoptosis, we tested the specific effects of several antagonists of Ado receptors or inhibitors of Ado transporter on the induction of apoptosis. Treatment of dipyridamole (DPD), an Ado transport inhibitor, effectively suppressed both c-Myc reduction and DNA fragmentation, suggesting that the induction of apoptosis and down-regulation of c-Myc is mediated by active Ado transporter. It was another evidence supporting the entrance of Ado into cells undergoing apoptosis that Ado cytotoxicity was potentiated by a addition of methylation cycle intermediates. These results suggest that the active Ado transporter-mediated Ado entrance into HL-60 cells leads to the induction of apoptosis through down-regulation of c-Myc.

OBJECTIVES: Knowledge about the management status of diabetic melitus (DM) is essential to improve diabetic management. Moreover, low income is associated with poor adherence to treatment and increased mortality. This study was performed to evaluate the management status of DM in low-income patients in a rural area. METHODS: We enrolled 370 patients with type 2 DM living in Gokseong county, JeollaNamdo. A well-trained examiner measured the height, weight, waist circumference, blood pressure, total cholesterol, triglyceride, high density lipoprotein cholesterol, fasting blood sugar and glycosylated hemoglobin (HbA1c) levels. Carotid ultrasonography was used to measure carotid artery carotid artery intima media thickness (IMT) and plaque. ankle-brachial index (ABI) was used to evaluate peripheral artery disease. A fundoscopic examination was performed to evaluate diabetic retinopathy. A history of diabetes complications and health-related questionnaires were also completed. RESULTS: The age of diabetic subjects was 68.7+/-8.7 years and the duration of diabetes was 8.9+/-8.2 years. Most (63.5%) had hypertension, and 45.7% had triglycerides below 150 mg/dl, 38.1% had low density lipoprotein cholesterol (LDL) cholesterol below 100 mg/dl, 48.7% had urine albumin to creatinine ratio (UACR) below 30 mg/g. Less than half (45.9%) achieved the goal of HbA1c less than 7% suggested by the American Diabetes Association (ADA). 10.6% had peripheral vascular disease, 11.9% had retinopathy, and 60.8% had chronic kidney disease. CONCLUSIONS: DM management in low income patients is very poor and requires further work to improve.

BACKGROUND: Continuous interscalene block has been known to improve postoperative analgesia after arthroscopic shoulder surgery. This was a prospective study investigating the ultrasound-guided posterior approach for placement of an interscalene catheter, clinical efficacy and complications after placement of the catheter. METHODS: Forty-two patients undergoing elective arthroscopic shoulder surgery were included in this study and an interscalene catheter was inserted under the guidance of ultrasound with posterior approach. With the inplane approach, the 17 G Tuohy needle was advanced until the tip was placed between the C5 and C6 nerve roots. After a bolus injection of 20 ml of 0.2% ropivacaine, a catheter was threaded and secured. A continuous infusion of ropivacaine 0.2% 4 ml/hr with patient-controlled 5 ml boluses every hour was used over 2 days. Difficulties in placement of the catheter, clinical efficacy of analgesia and complications were recorded. All patients were monitored for 48 hours and examined by the surgeon for complications within 2 weeks of hospital discharge. RESULTS: Easy placement of the catheter was achieved in 100% of the patients and the success rate of catheter placement during the 48 hr period was 92.9%. Postoperative analgesia was effective in 88.1% of the patients in the post anesthetic care unit. The major complications included nausea (7.1%), vomiting (4.8%), dyspnea (4.8%) and unintended vascular punctures (2.4%). Other complications such as neurologic deficits and local infection around the puncture site did not occur. CONCLUSIONS: The ultrasound-guided interscalene block with a posterior approach is associated with a success high rate in placement of the interscalene catheter and a low rate of complications. However, the small sample size limits us to draw definite conclusions. Therefore, a well-designed randomized controlled trial is required to confirm our preliminary study.

PURPOSE: To assess the usefulness of the talocalcaneal C sign in the diagnosis of subtalar coalition, as seen on lateral radiographs of the ankle. MATERIALS AND METHODS: Lateral radiographs of 12 ankles in 11 patients were included in this study. Twelve subtalar coalitions were confirmed by surgery (n=6), or by CT and/or MR (n=6). The presence of the talocal-caneal C sign on lateral ankle radiographs was determined. RESULTS: The C sign was continuous in six feet and interrupted in the remaining six. Subtalar coalition occurred simultaneously in the middle and posterior subtalar joints in two cases, the posterior subtalar joint only in six, and in the middle subtalar joint only in four. In six cases confirmed at surgery, subtalar coalitions consisted of both synostosis and non-osseous fusion (synchondrosis and/or syndesmosis) and in one case of middle subtalar coalition, there was a bony bridge. The remaining six cases, confirmed at CT or MRI, involved both synostosis and non-osseous fusion (n=1) or non-osseous fusion only (n=5). CONCLUSION: In the diagnosis of subtalar coalition, the talocalcaneal C sign, seen on lateral radiographs of the ankle, is a useful indicator.

Posterior reversible encephalopathy syndrome (PRES) is a rare clinico-radiological syndrome that is characterized by an acute onset of headache, vomiting, visual abnormalities, confusion, and/or seizures and is typically accompanied with edema of predominantly posterior portions of the cerebral hemispheres. Here, we report a case of PRES with cerebral hemorrhage that occurred in a female pediatric patient with uncontrolled nephrotic syndrome. The patient's magnetic resonance imaging (MRI) studies showed asymmetric white matter abnormalities, cerebral hemorrhage, and restricted diffusion. After controlling her hypertension and nephrotic syndrome, her neurologic symptoms improved, and follow-up MRI findings revealed interval resolving of the white matter lesions.
