BACKGROUND: The purpose of this study was to ascertain the prevalence of vitamin D deficiency and risk factors associated with mortality in patients > or =50-year-of-age with hip fractures. METHODS: A total of 489 patients > or =50-year-of-age who sustained a hip fracture from January 2010 to October 2014 were followed-up for a minimum of 1 year. Clinical and radiological outcomes were evaluated including prevalence of vitamin D deficiency. Crude mortality rates were calculated, and the effects of different risk factors on mortality were assessed. RESULTS: Vitamin D deficiency was present in 76.5% of cases (n=237). The prevalence of vitamin D insufficiency was 12.3%, and only 11.2% of patients had normal vitamin D levels. Accumulated mortality was 11% (54 patients) at 1 year. A univariate analysis showed that vitamin D deficiency (P=0.012), age (P<0.001), BMI (P<0.001), type of management (P<0.001), American Society of Anesthesiologists (ASA) score (P=0.009), pre-fracture ambulatory status (P<0.001), and osteoporosis (P<0.001) were associated with mortality. A multivariate analysis performed using a Cox proportional hazards model demonstrated that ASA score (P=0.001) and pre-fracture ambulatory status (P=0.011) were independently associated with mortality after hip fracture. CONCLUSIONS: We did not find a relationship between serum 25-hydroxy-vitamin D levels and mortality after hip fracture, although we observed a high prevalence of vitamin D deficiency and a significant association with mortality in the univariate analysis.

Pelvic kidney, an ectopic renal mass caused by developmental failure, is a rare condition. Here, we report a case of laparoscopic anterior resection in a patient with a solitary pelvic kidney. A 76-year-old man was diagnosed as having rectosigmoid colon cancer. Preoperative computed tomography revealed a left ectopic kidney in his pelvis. Computed tomographic angiography and retrograde pyelography were performed preoperatively to identify the renal vessels and the ureter. To keep the surgical plane intact for complete mesocolic excision, a complete laparoscopic anterior resection was safely performed without open conversion, and there was no injury to the pelvic kidney. The patient was discharged on postoperative day eight without any complication. No deterioration of renal function was observed after surgery. This report describes a case of laparoscopic anterior resection that was safely performed without conversion to open surgery in a patient with a pelvic ectopic kidney.

PURPOSE: Nowadays laparoscopic appendectomy is widely practiced in developed countries. The purpose of this study was to evaluate laparoscopic appendectomy in comparison with open appendectomy. METHODS: On hundred cases each of laparoscopic appendectomy and open appendectomy, performed between February 2001 and June 2002, were reviewed for age, sex, operative time, hospital days, time for first meal, number of used parenteral analgesia, number of OPD visits, etc. RESULTS: Operative time was longer in the laparoscopic appendectomy group (P>0.05) and the number of used parenteral analgesia was slightly higher in the laparoscopic group (P>0.05). However, recovery time for diet was slightly shorter in the laparoscopic group (P>0.05). None of these trends were statistically significant. The times of OPD visit after discharge was less in the laparoscopic group (P<0.05). The hospital days of pathological simple appendicitis were shorter in the laparoscopic appendectomy group (P<0.05). In the laparoscopic group, intraabdominal abscess was developed in 2 cases, wound infection in 4, and intestinal obstruction in 2. The conversion rate to open appendectomy was 7% (7/100) in the laparoscopic group. CONCLUSION: Laparoscopic appendectomy can shorten overall OPD follow up days and in case of simple appendicitis, laparoscopic appendectomy can also shorten hospital days.

BACKGROUND: Osteoporosis treatment following hip fracture is well known to not enough. We previously performed intervention study for orthopaedic surgeon's education and reported twofold increase in osteoporosis detection and treatment rate observed between 2005 and 2007. This follow-up observational study was conducted to find out the rate in which a diagnostic workup and treatment for osteoporosis were done in patients with hip fracture. METHODS: Medical records and radiographs in patients who were older than 50 years and diagnosed as having femoral neck or intertrochanteric fractures at 8 hospitals in Jeju island, South Korea from 2008 to 2011 were reviewed. The numbers of patients who were studied with bone densitometry and who were treated for osteoporosis after the diagnosis of hip fracture were analyzed. RESULTS: Nine hundred forty five hip fractures (201 in 2008, 257 in 2009, 265 in 2010, and 304 in 2011) occurred in 191 men and 754 women during the study periods. The mean age of the patients was 79.7 years. The mean rate of osteoporosis detection using dual energy X-ray absorptiometry was 36.4% (344/945 hips) (ranged from 24.2% in 2009 to 40.5% in 2011). The mean initiation rate of osteoporosis treatment was 23.1% (218/945 hips) (ranged from 20% in 2009 to 29% in 2008). CONCLUSIONS: Detection and treatment rate of osteoporosis following hip fracture during follow-up periods was still not enough. Additional intervention studies are required to further improvement of osteoporosis treatment rates after hip fracture.

Purpose: This study was performed to compare the efficacies of newly developed needle grasper-assisted (Endo Relief) single-incision laparoscopic appendectomy (NASILA) and single-incision laparoscopic appendectomy (SILA). Methods: This study enrolled 110 patients with acute appendicitis without periappendiceal abscess, diagnosed using computed tomography, who were randomized to the SILA (n = 54) and NASILA groups (n = 56) between December 2017 and August 2018 (6 patients withdrawn). The NASILA technique entailed a small umbilical incision for the glove port (equivalent to that for a 12-mm trocar), and a 2.5-mm suprapubic incision for the needle grasper. Results: The SILA and NASILA groups included 49 (male, 61.2%) and 55 (male, 54.5%) patients, respectively. Age, body mass index, abdominal surgical history, symptom duration, and use of patient-controlled analgesia did not differ significantly between the 2 groups. The main wound size was significantly smaller in the NASILA group than in the SILA group (1.8 ± 0.4 cm vs. 2.2 ± 0.4 cm, P < 0.001). The operative time and estimated blood loss did not differ significantly between both groups. The immediate postoperative pain score, i.e., the primary endpoint, was significantly lower in the NASILA group than in the SILA group (2.33 ± 0.98 vs. 2.82 ± 1.29, P = 0.031). The complaints for scar status 1 month postoperatively did not differ significantly between the groups. Conclusion NASILA could attenuate postoperative pain by minimizing the size of the surgical wound; further, NASILA may not be inferior to SILA in terms of cosmetic results.

PURPOSE: Laparoscopic cholecystectomy (LC) has replaced open cholecystectomy (OC) for the majority of patients. However, a minority of patients still require conversion to open cholecystectomy during the perioperative period. This study was designed to determine the contributing factors related to conversion to open cholecystectomy. METHODS: The data from 3,510 laparoscopic cholecystectomies, performed at Chung-Ang university hospital from September 1990 to June 2001, were reviewed retrospectively. Pre-operative laboratory data, post-operative pathologic findings, complications, and the reasons for conversion to open cholecystectomy were evaluated. RESULTS: Sixty six (1.88%) of 3,510 patients were converted to open surgery, due to bleeding (39%), adhesion (26%), bile duct injury (23%) and inflammation (6%). These conversion cases were more prevalent in males and needed longer hospital stay. Thickening of the gallbladder wall and gangrenous cholecystitis were frequent pathologic findings among the conversion cases. CONCLUSION: Thickening of the gallbladder wall, inflammation and anatomical variation of the gallbladder were important factors for conversion to open surgery. Thus, these predictive findings allow the surgeons to preoperatively discuss the higher risk of conversion and allow for an earlier judgement and decision on conversion if intraoperative difficulty is encountered.

PURPOSE: The prognosis for primary gallbladder cancer is very poor. Because of the lack of specific symptoms, late diagnosis, advanced stage, and ineffective treatment are typical. The purpose of the present study was to investigate the early diagnostic factors that improve the survival rate, by comparing a preoperatively diagnosed group with a postoperatively diagnosed group. METHODS: This study was a clinical analysis of our surgical experience with primary gallbladder carcinomas during the 6 years from 1992 to 1997 at Chung-Ang University in Korea. RESULTS: The incidence of gallbladder carcinomas was 0.6% of the 6132 biliary-tract operations performed during the 6 years (suspected group: unsuspected group=15:23). The sex ratio of males to females was 1 to 2.46 with female predominance. Primary GB cancer was seen most commonly in patients in their 50s and 60s, and this group accounted for 68.4% of the entire group and had a median age of 65 years. The most common clinical manifestation was right upper abdominal pain in 27 cases (71.1%). The duration of the illness in preoperatively suspected patients was much shorter than that for intraoperatively or only pathologically diagnosed patients (p=0.046) As for diagnostic methods, ultrasound and abdominal CT scans were performed, and the preoperative diagnostic accuracies were 31.6% and 69.3%, respectively. The patients were grouped according to the staging system of Nevin et al. The five stages were classified as follows: stage I (suspected group-0 cases; unsuspected group-2 cases), stage II (1 case; 5 cases), stage III (1 case; 2 cases), stage IV (7 cases; 9 cases), and stage V (6 cases; 5 cases). Adenocarcinoma was the most common type of gallbladder cancer (32 cases: suspected group-10 cases; unsuspected group-22 cases), followed by squamoadenocarcinoma (3 cases: 2 cases/1 case), neurogenic carcinoma (1 case: 1 case/0 cases), histiocytoma (1 case: 1 case/0 cases), and papillary carcinoma (1 case: 1 case/0 cases). The total cumulative 1-year, 2-year, and 3-year survival rates were 67.7%, 37.6%, and 12.1%, respectively (suspected: 46.2%, 15.4%, and 0%; unsuspected: 71.4%, 52.9%, and 23.2%). The cumulative survival rates for patients in the unsuspected group were higher than those for patients in the suspected group (p=0.008). CONCLUSION: The survival rate of the preoperatively unsuspected group was better than that of the suspected group. The survival improvement depended the invasion by the gallbladder carcinoma. We suggest that the survival rate should be improved by early detection of the gallbladder carcinoma and on extended operation. Conclusively, further evaluation of patients with etiologic factors should be done, more specific exams (CT or MRI) should be evaluated, and an acceptable operation should be done.

Background: This prospective randomized controlled study aimed to determine the effects of abdominal massage on constipation management in elderly patients with hip fractures. Methods: From August 2017 to December 2018, patients aged above 65 years with hip fractures (n = 88) were randomly assigned to a massage group that received a bowel massage (n = 48) or a control group that did not receive a bowel massage (n = 40). Patients in the bowel massage group received a bowel massage from a trained caregiver after breakfast at approximately 9:00 AM for an hour. On admission, 5 days after surgery, and on the day of discharge, the patient’s normal and actual defecation pattern, stool consistency, and any problems with defecation were assessed through a structured interview. The questionnaire comprising the Bristol Stool Scale, patient assessment of constipation, time to defecation, medication for defecations, failure to defecate, cause of admission, admission period, and date of surgery were recorded. Statistical analyses were performed 5 days after surgery and on the day of discharge. Results: The mean age of the study cohort was 81.4 years (range, 65–99 years). The number of constipation remedies was significantly lower in the massage group than in the control group on postoperative day (POD) 5 and at discharge (9 vs. 15, p = 0.049 and 6 vs. 11, p = 0.039, respectively). The number of defecation failures was significantly lower in the massage group than in the control group (10 vs. 17, p = 0.028) on POD 5. However, the number of defecation failures at discharge was not significantly different between the two groups ( p = 0.131). The development of postoperative ileus ( p = 0.271) and length of hospital stay ( p = 0.576) were not different between the groups. Conclusions The number of constipation remedies was significantly lower in the massage group than in the control group on POD 5 and discharge, and the number of defecation failures was significantly lower in the massage group than in the control group on POD 5. Therefore, abdominal massage may be considered as an independent nursing initiative for constipation management.
