Risk factors for prolonged hospitalization and delayed treatment completion after laparoscopic appendectomy in patients with uncomplicated acute appendicitis

Purpose@#We sought to identify the risk factors for prolonged hospitalization and delayed treatment completion after laparoscopic appendectomy in patients with uncomplicated acute appendicitis. @*Methods@#The study retrospectively analyzed 497 patients who underwent laparoscopic appendectomies for uncomplicated appendicitis between January 2018 and December 2020. The patients were divided into an early discharge group (≤2 days) and a late discharge group (>2 days) based on the length of hospital stay (LOS). The patients were also divided into uneventful and complicated groups according to the need for additional treatment after standard follow-up. @*Results@#Thirty-seven patients (7.4%) were included in the late discharge group. The mean LOS of the late discharge groups was 3.9 days. There were significant differences according to age, preoperative C-reactive protein (CRP), and operative time between the 2 groups. Only operative time was significantly associated with prolonged LOS in multivariate analysis. Thirty-five patients (7.0%) were included in the complicated group. The mean duration of treatment in the uneventful and complicated groups was 7.4 and 25.3 days, respectively. Significant differences existed between the uneventful and complicated groups in preoperative body temperature, preoperative CRP levels, maximal appendix diameter, and the presence of appendicoliths. In multivariate analysis, preoperative CRP levels and maximal appendix diameter were independent predictors of delayed treatment completion. @*Conclusion@#Shorter operative time is desirable to ensure minimal hospital stay in patients with uncomplicated appendicitis. Further efforts are needed to ensure that patients with uncomplicated appendicitis do not experience delayed treatment completion after laparoscopic appendectomies.

First-generation therapy for varicose veins: medication, compression, sclerotherapy, and stripping

Improving the understanding varicose veins (VV) is increasing due to life extension and concerns regarding quality of life. Recently, endovascular treatment has become more common, even in mild cases. Excessive procedures are often performed before conservative and non-surgical treatments. We aimed to explain the efficacy of medication, compression, sclerotherapy, and stripping of treatments and to consider the appropriate indications for many treatment methods, including endovascular procedures.Current Concepts: Venoactive drugs can be used as first-line agents for symptoms, such as edema, at all stages of varicose vein. These are effective adjuvant agents and can help achieve compression before and after procedures. Compression therapy is effective for skin change and ulcers and is excellent for the improvement of symptoms. Sclerotherapy has been widely used as an adjuvant treatment, but recently, its indications have been expanded for non-invasive causes. Traditional high ligation and stripping is still the recommended treatment option for recurrent or complicated varicose veins.Discussion and Conclusion: The patients’ symptoms should be evaluated more critically than assessing only the venous reflux using ultrasound. Additionally, objective evaluation of various causes of lower extremity discomfort should be considered. Treatment according to appropriate indications, such as medication, compression, sclerotherapy, stripping, and endovascular therapy, can improve the patients’ quality of life and prevent complications.

Effect of Age on Laparoscopic Surgery and Postoperative Chemotherapy in Elderly Patients With Colorectal Cancer

Purpose@#We aimed to evaluate the postoperative complications of laparoscopic colorectal cancer (CRC) surgery and the adverse events of postoperative chemotherapy in elderly patients compared to younger patients and to identify the factors influencing the termination of postoperative chemotherapy. @*Methods@#Between June 2015 and May 2018, 188 patients with CRC underwent laparoscopic surgery with curative intent.Patients aged ≥ 70 were defined as elderly. Postoperative complications and adverse events of chemotherapy were assessed by using the Clavien-Dindo classification and the Common Terminology Criteria for Adverse Events, respectively. The clinicopathological factors were analyzed retrospectively. @*Results@#Seventy-eight patients were considered elderly with a mean age of 77.5 ± 5.5 years. Overall postoperative complications occurred in 68 patients (36.2%). Age and primary tumor location were independent predictors of overall postoperative complications. Smoking history was the only independent predictor of major postoperative complications. Of 113 patients who were recommended postoperative chemotherapy, 90 patients (79.6%) received postoperative chemotherapy.Overall adverse events occurred in 40 patients (44.4%). The American Society of Anesthesiologists physical status classification and chemotherapy regimen were significantly associated with overall adverse events. The chemotherapy regimen was the only factor significantly associated with severe adverse events. Of 90 patients, postoperative chemotherapy could not be completed in 11 (12.2%). Age was the only factor significantly associated with stopping postoperative chemotherapy (P = 0.003). @*Conclusion@#This study shows that laparoscopic CRC surgery and postoperative chemotherapy were feasible in elderly patients. Further efforts are needed to ensure that elderly patients have the opportunity to make informed decisions regarding postoperative chemotherapy.

Acute Traumatic Arterial Occlusions Combined with Massive Morel-Lavallée Lesions Treated by Percutaneous Angioplasty, Multiple Debridements and Skin Grafts

Morel-Lavallée lesions (MLL) create pre-fascial space by shearing the subcutaneous tissues away from the underlying fascia, in a patient with trauma. Necrosis of the overlying skin can develop over a wide area of the lesion. The lesion might be contaminated by the surgical site due to careless intrusion when treating the combined arteriopathy. A 70-year-old woman presented with avulsion of the skin over the right foot and bilateral leg pain following a car accident. Computed tomography showed bilateral popliteal artery occlusion with large hematoma on both legs. Percutaneous angioplasty was performed with successful restoration of the flow. However, the skin color changes over time. Necrosis of the skin occurred over a wide area of the right leg. Extensive debridement was performed, and the defect was covered with a skin graft. MLLs can occur in patients with multiple traumas, multiple vascular injuries, and complex skeletal injury. Vascular surgeons treating multiple traumas should be aware of the diagnostic and management options for MLL. It should be diagnosed early because it can be difficult to manage once the overlying skin develops necrosis.

Risk of osteoporosis and fracture in long-term breast cancer survivors

Purpose@#High incidence of osteoporosis has been reported in breast cancer patients due to early menopause triggered by adjuvant treatment and temporary ovarian function suppression. In this study, we sought to determine whether long-term breast cancer survivors had an elevated risk of low bone density compared to the general population. @*Methods@#Long-term breast cancer survivors who had been treated for more than 5 years were selected for this study. Data were obtained from medical records and using a questionnaire from the Korea National Health and Nutrition Examination Survey (KNHANES). An agematched non-cancer control group was selected from the KNHANES records. Incidence of fracture and bone mineral density (BMD) were compared between the two groups. @*Results@#In total, 74 long-term breast cancer survivors and 296 non-cancer controls were evaluated. The incidence of fracture did not differ between the two groups (P=0.130). No differences were detected in lumbar BMD (P=0.051) following adjustment for body mass index, while hip BMD was significantly lower in breast cancer survivors (P=0.028). Chemotherapy and endocrine treatment were not related to low BMD in breast cancer survivors. In more than half of the survivors, the 10-year risk of osteoporotic fracture was less than 1%. @*Conclusion@#Long-term breast cancer survivors had low bone density but a comparable risk of fracture compared to non-cancer agematched controls. Further studies on the factors related to low bone density in long-term breast cancer survivors are required.

Cut-down method for perm catheter insertion in patients with completely occluded internal jugular vein

The primary site for a hemodialysis catheter insertion is the right internal jugular vein (IJV) followed by the left IJV and subclavian vein. In cases when veins of the upper extremities are exhausted, femoral veins are an alternative insertion location. Femoral catheter insertions should only be used for short periods because of the increased risk of infection. There is a percutaneous technique to recanalize occluded central veins for hemodialysis catheter insertion. We experienced success with a cut-down method for permcath through a completely occluded IJV. We, therefore, find surgical recanalization to be better than percutaneous method in terms of cost and safety.

Long-term cardiac composite risk following adjuvant treatment in breast cancer patients

PURPOSE: Cardiotoxicity is a serious late complication of breast cancer treatment. Individual treatment risk of specific drugs has been investigated. However, studies on the evaluation of the composite risk of chemotherapeutic agents are limited.METHODS: We retrospectively analyzed the medical records of breast cancer patients who received adjuvant treatment and had available serial echocardiography results. Patients were assigned to subgroups based on chemotherapy containing anthracyclines (A), anthracyclines and taxanes (A+T), and radiotherapy (RT). The development of cardiac disease and serial ejection fraction (EF) were reviewed. EF decline up to 10% from baseline was considered grade 1 cardiotoxicity and EF decline >20% or absolute value < 50% was considered grade 2 cardiotoxicity. The most recent medical records and echocardiography results over 1 year of chemotherapy completion were also reviewed. Late cardiotoxicity was defined as a lack of recovery of EF decline or aggravated EF decline from baseline.RESULTS: In total, 123 patients were evaluated. A small reduction in EF was observed after chemotherapy in both chemotherapy groups. There were no significant differences between groups A and A+T in EF decline following chemotherapy. We could not find any differences in composite risk between the chemotherapy groups and the RT group during follow-up. Late cardiotoxicity was seen in 15.45% of patients. During follow-up, three patients were diagnosed with dilated cardiomyopathy.CONCLUSION: There was no significant composite risk elevation following adjuvant treatment of breast cancer. However, late cardiotoxicity was considerable and further research in this direction is necessary.

Long Term Outcomes of Arteriovenous Grafts for Hemodialysis in Lower Extremities

PURPOSE: The lower extremity has received its fair share of attention as a vascular access site in patients who have exhausted their upper arm vessels. However, experiences with lower extremity arteriovenous grafts (AVGs) have so far been disappointing because of high infection rates and severe limb ischemia. We report our experience with hemodialysis access from the lower extremity. MATERIALS AND METHODS: A retrospective review of 60 lower extremity AVGs created between January 2003 and December 2011 was performed. Age, sex, etiology of end-stage renal disease and complications were tabulated. Primary and secondary patency rates were determined. RESULTS: The average age of the study population was 56 years and 38 patients were female. Renal failure was associated with hypertension in 40 (66.7%) patients, diabetes in 28 (46.7%) patients and cardiovascular disease in 9 (15.0%) patients. The follow-up period was 8–108 months. Fifty-four patients had bilateral central vein stenosis. Seven (11.7%) patients had primary failure of their AVG. There was no operation-related death. Primary and secondary patency rates were: 66% and 90% at 1 year, 40% and 90% at 2 years, 27% and 87% at 3 years, and 18% and 87% at 5 years, respectively. There were 105 postoperative complications that developed in 67 patients. Postoperative complications were: thrombosis (30), proximal vein stenosis (56), infection (9), bleeding with hematoma (1), perigraft seroma (3), steal syndrome (2), and pseudoaneurysm (4). CONCLUSION: A lower extremity AVG seems to be a viable option in patients with unusable upper extremity veins.

Hybrid Operation for Arteriovenous Malformation in Left Soleus Muscle with Embolization of Feeding Artery and En Bloc Resection: A Case Report / 대한족부족관절학회지

Arteriovenous malformations (AVMs) are characterized by the presence of abnormal connections between feeding arteries and draining veins. It is generally assumed that symptomatic lesions can preferably be treated. Due to high arterial blood flow, there is a risk of bleeding with surgical excision alone, which can be massive and life threatening during the operation. According to recent advances in interventional technique, a hybrid approach using embolization of the feeding artery with subsequent immediate excision of the AVM for successful management of vascular lesions could be applied to AVMs. Herein, we describe a case of successful excision of AVM in the left soleus muscle using a hybrid approach.

Alternative prosthetic vascular access creation using subscapular artery as inflow to prevent dialysis access related steal syndrome

In patients highly suspected of developing steal syndrome, the subscapular artery may be a good supplier for functional prosthetic arteriovenous access, as well as a good solution for the prevention of steal syndrome. A 51-year-old woman was preparing to have a loop shaped polytetrafluoroethylene (PTFE) graft placed at the left upper extremity. The diameter of subscapular the artery was 3 mm. Arterial calcification was not evident. The diameter of the basilic vein was 6 mm. A 50-cm long 4-7 mm tapered PTFE graft was placed in a loop shape between both skin incisions. The patient was uneventfully discharged at postoperative day 4 without any remaining steal syndrome. The PTFE graft was well-functioning during the follow-up period. The patient did not experience symptoms of steal syndrome any longer.

Large cutaneous apocrine carcinoma occurring on right thigh aggravated after moxa treatment

Primary cutaneous apocrine carcinoma is a rare adnexal tumor of the skin that occurs mainly in the axilla, anogenital area while the scalp and the lower extremities, especially the thigh, are very unusual sites. However, clinical or pathologic characteristics have not been well established due to a paucity of this tumor. Herein, we report very unusual case of apocrine carcinoma present as a huge mass in the lateral thigh of 77-year-old woman, which was aggravated abruptly after an irritation by moxa treatment, with a brief review of the literature.

Transfusion free radical antegrade modular pancreaticosplenectomy of metastatic neuroendocrine tumor of the pancreas in Jehovah's Witness patient

In a popular sense, Jehovah's Witnesses (JW) have their creeds, one of which is refusal of blood transfusion. Such refusal may impinge on their proper management, especially in critical situations. We present a case of successful bloodless multimodality therapy, which was performed for a JW. The patient was a 49-year-old woman and JW who had general weakness 7 days before admission. She was diagnosed with a pancreatic neuroendocrine tumor (PNET) with hepatic metastases. Transcatheter arterial chemoembolization and Sandostatin LAR injection were performed, and then she was given a transfusion-free Radical antegrade modular pancreatosplenectomy sequentially. We gave recombinant human erythropoietin and iron hydroxide sucrose complex daily for five days after surgery. She was discharged at postoperative day 12 without any surgical complications. Multimodality therapy is very important for optimal treatment of PNET. Along with intimate interdepartmental cooperation, careful patient selection and appropriate perioperative management could possibly enhance the surgical outcome.

Posterior triangle approach for lateral in-plane technique during hemodialysis catheter insertion via the internal jugular vein

A recent widespread concept is that ultrasound-guided central venous catheter insertion is a mandatory method. Some techniques have been introduced for ultrasound-guided central venous catheterization. Among them, short-axis lateral in-plane technique is considered to be the most useful technique for internal jugular vein access. Therefore, we used this technique for the insertion of a large-bore cuffed tunneled dual-lumen catheter for hemodialysis. Additionally, a lesser number of catheter angulations may lead to good flow rates and catheter function; we recommend that skin puncture site in the neck at the posterior triangle is better than the Sedillot's triangle. Using this approach, we can reduce the possible complications of pinching and kinking of the catheter.

The Usefulness of Laparoscopy in the Treatment of Incarcerated Internal Hernia through a Defect in the Broad Ligament

Hernias through the broad ligament are rare with a reported incidence of only 4-7% of cases of internal hernias. Here, we report on a rare case of incarcerated internal hernia through a spontaneous defect in the broad ligament which was repaired using a laparoscopic technique. A 41-year-old female was admitted with colic abdominal pain. Laparoscopic exploration was performed for the diagnosis of intestinal obstruction. Laparoscopic examination confirmed an approximately 10-cm-long ileal loop herniated in the anterior to posterior direction through a left broad ligament defect. A large defect in the broad ligament was closed by an intracorporeal continuous running suture. The patient was highly satisfied with the cosmetic result. In conclusion, laparoscopy could be particularly helpful during pelvic surgery, which usually requires large skin incisions to ensure a good field of view. This approach was cosmetically effective, decreased the postoperative complications, and promoted early recovery to usual activity.

Transplantation of a Horseshoe Kidney Found During Harvest Operation of a Cadaveric Donor: A Case Report

A 34-yr-old female was diagnosed as being brain dead. Preoperative ultrasound revealed no abnormal focal lesions. However, the horseshoe kidney was identified during organ harvest. En bloc nephrectomy was performed. The kidney was divided at the midline of isthmus. The divided right kidney was discarded due to numerous arteries and veins. The divided left kidney was transplanted. After declamping, the kidney was well perfused and started clearing. Resistive index was 0.72. Glomerular filtration ratio was 84.69 mL/min on postoperative day 14. The horseshoe kidney can be successfully transplanted and could be a good solution for the shortage of organ donors.
