Forty-five adults with type IV-A choledochal cysts (CDC) who underwent extrahepatic cyst excision from January 2013 to December 2021 were followed up for a median interval of 25 months (range, 2 to 10 years) to observe the long-term complications in the remaining intrahepatic cyst. Late complications in varying combinations were seen in 10 patients, which included cholangitis and/or intrahepatic stones in 9 patients, intrahepatic bile duct stenosis with stones in 2 patients, anastomotic stricture in 6 patients, and left lobar atrophy with intrahepatic stones in 3 patients. Out of 6 patients who required re-do hepaticojejunostomy (HJ), three patients had left lobe atrophy with patent HJ anastomosis and a recurrent attack of cholangitis on follow-up at 3, 8, and 10 years. Complications occur frequently after extrahepatic cyst excision for type IV-A CDC and require a long-term follow-up.

The aim of this study was to determine predictive risk factors implicated in complications in dogs with esophageal foreign bodies. Medical records of 72 dogs diagnosed with esophageal foreign bodies by endoscopy were reviewed retrospectively. Factors analyzed included age; breed; gender; body weight, location, dimension, and type of foreign body; and duration of impaction. To identify risk factors associated with complications after foreign body ingestion, categorical variables were analyzed using the chisquare or Fisher's exact tests and multivariate analysis, as appropriate. Complications secondary to esophageal foreign body ingestion included megaesophagus, esophagitis, perforation, laceration, diverticulum, and pleuritis. Univariate analysis revealed that the location and duration of impaction after foreign body ingestion were associated with an increased risk of esophageal laceration and perforation. Multivariate analysis showed that age, duration of impaction, and foreign body dimension were significant independent risk factors associated with the development of complications in dogs with esophageal foreign bodies. In conclusion, these results showed that longer duration of impaction and larger foreign body dimensions may increase the risks of esophageal laceration, perforation, and plueritis in dogs.

Objectives : This study was designed to quantify the characteristics, main diagnosis and complications in the intensive care unit (ICU) at an Oriental Medical Hospital. Methods : The medical records of 44 patients admitted to the ICU at Kyunghee Oriental Medical Hospital between January 1, 2011 and December 31, 2011 were reviewed. Basic characteristics of patients, admission channel, main diagnosis, east-western medical therapy, mortality, and complications were investigated retrospectively based on medical notes. Results : 1. The total number of patients was 44. Males were 63.6%, females 36.3%. Average admission days was 15.9. 2. The most frequent age group is eighties, 38.6%. 3. The most frequent disease is cerebrovascular disease, 61.3%. 4. The medical therapy done after admission to ICU was intubation. Central vein insertion was performed next, followed by Foley's catheter insertion, ventilator, tracheostomy, nasogastric intubation, and thoracentesis in order. The proportion of Oriental medical treatment provided to the patients of ICU was as follows: herbal medication only 6.8%; herbal medication plus acupuncture 31.8%; herbal medication, acupuncture electro-acupuncture, plus subcutaneous acupuncture 2.3%; and none 27.3%. 5. The number of cases of complications occurred since ICU admission was 18. The most frequently observed complication was infection, including 6 cases of pneumonia and 4 cases of urinary tract infection. Conclusions : We suggest that ICUs of Oriental medical hospitals need to be managed effectively to treat diseases including cerebrovascular disease and prevent complications.

Background A pectoralis major flap is one of the standard tools for the reconstruction of defects of the head and neck. Despite the technical advancement in free tissue transfer in head and neck reconstruction, the benefits of a pectoralis major flap should not be overlooked. The purpose of this study is to evaluate our 17 years of experience in reconstructing defects of the head and neck region using the pectoralis major flap. Methods We retrospectively reviewed the medical records of 112 patients (120 cases) who underwent pectoralis major flap operations for head and neck reconstruction during a period ranging from 1994 to 2010. Results In our series, no total necrosis of the flap occurred. Of the total cases, 30.8% presented with flap-related complications. Major complications occurred in 20% of all of the cases but were then all successfully treated. The male sex was correlated with the occurrence of overall complications (P=0.020) and major complications (P=0.007). Preoperative albumin levels of <3.8 g/dL were correlated with the formation of fistula (P=0.030). Defects of the hypopharynx were correlated with the occurrence of major complications (P=0.019) and the formation of fistula (P=0.012). Secondary reconstructions were correlated with the occurrence of overall complications (P=0.013) and the formation of fistula (P=0.030). Conclusions A pectoralis major flap is still considered to be a safe, versatile one-stage reconstruction procedure in the management of the defects of head and neck and the protection of the carotid artery.

Purpose: This study was conducted to compare the cumulative survival rates (CSRs) and the incidence of postloading complications (PLCs) between a bone-level internal connection system (ICS-BL) and an external connection system (ECS). Methods: The medical records of patients treated with either a ICS-BL or ECS between 2007 and 2010 at Asan Medical Center were reviewed. PLCs were divided into two categories: biological and technical. Biological complications included >4 mm of probing pocket depth, thread exposure in radiographs, and soft tissue complications, whereas technical complications included chipping of the veneering material, fracture of the implant, fracture of the crown, loosening or fracture of the abutment or screw, loss of retention, and loss of access hole filling material. CSRs were determined by a life-table analysis and compared using the log-rank chi-square test. The incidence of PLC was compared with the Pearson chi-squared test. Results: A total of 2,651 implants in 1,074 patients (1,167 ICS-BLs in 551 patients and 1,484 ECSs in 523 patients) were analyzed. The average observation periods were 3.4 years for the ICS-BLs and 3.1 years for the ECSs. The six-year CSR of all implants was 96.1% (94.9% for the ICS-BLs and 97.1% for the ECSs, P=0.619). Soft tissue complications were more frequent with the ECSs (P=0.005) and loosening or fracture of the abutment or screw occurred more frequently with the ICS-BLs (P<0.001). Conclusions: Within the limitations of this study, the ICS-BL was more prone to technical complications while the ECS was more vulnerable to biological complications.

We retrospectively reviewed the cases in which complications occurred during below-the-knee (BTK) endovascular treatments that were performed at our hospital from 2005 to 2014. Several interesting cases have been described herein. All the patients had diabetes and non-healing wounds on their feet and/or rest pain in their foot or leg, and therefore, endovascular treatment was performed for the BTK arteries of the affected lower extremity. The complications that occurred during the procedure were classified into six categories-vascular spasm, flow limiting dissection, perforation, broken guidewire, distal thromboembolism, and unusual puncture site bleeding. Each complication has its own solutions and management. We discuss these different classes of complications and describe how cases of each type were managed.

Purpose: There have been local wound complications in patients who have received first aid after venomous snake bites. Yet first aid in relation to local wound complications has not been well studied. Methods: We conducted a 5-year retrospective study of 111 snake bite patients who visited the emergency departments of several medical centers between January 2004 and December 2008. We categorized the patients into those who had complications with inadequate first aid, those who had complications without first aid those who had complications with adequate first aid. We compared the genera characteristics and the laboratory and clinical findings of the three groups. Results: The ale o female ratio was 1.36. The most common bite site was fingers. The most common systemic symptom was dizziness (6.3%) and the most common complication was rhabdomyolysis (23.4%). The inadequate first aids group had more local complications (cellulitis, skin necrosis) than did the group with adequate first aid or the group with no first aids. Conclusion: Inadequate first aid after snake bite leads to local complications, so we must be careful to administer first aid after snake bite and evaluate this first aid in elation to local complications.

Complications experienced during lymphatic surgery have not been ubiquitously reported, and little has been described regarding how to prevent them. We present a review of complications reported during the surgical management of lymphedema and our experience with technical considerations to reduce morbidity from lymphatic surgery. A comprehensive search across different databases was conducted through November 2020. Based on the complications identified, we discussed the best approach for reducing the incidence of complications during lymphatic surgery based on our experience. The most common complications reported following lymphovenous anastomosis were re-exploration of the anastomosis, venous reflux, and surgical site infection. The most common complications using groin vascularized lymph node transfer (VLNT), submental VLNT, lateral thoracic VLNT, and supraclavicular VLNT included delayed wound healing, seroma and hematoma formation, lymphatic fluid leakage, iatrogenic lymphedema, soft-tissue infection, venous congestion, marginal nerve pseudoparalysis, and partial flap loss. Regarding intra-abdominal lymph node flaps, incisional hernia, hematoma, lymphatic fluid leakage, and postoperative ileus were commonly reported. Following suction-assisted lipectomy, significant blood loss and transient paresthesia were frequently reported. The reported complications of excisional procedures included soft-tissue infections, seroma and hematoma formation, skin-graft loss, significant blood loss, and minor skin flap necrosis. Evidently, lymphedema continues to represent a challenging condition; however, thorough patient selection, compliance with physiotherapy, and an experienced surgeon with adequate understanding of the lymphatic system can help maximize the safety of lymphatic surgery.

Purpose: This study was performed to investigate the type and frequency of end colostomy-related complications and to identify the risk factors for those complications. Methods: Retrospective analysis of medical records was made in 708 patients who underwent end colostomy in Samsung Medical Center between October 1994 and February 2005. The type was divided into stomal and peristomal complications: stomal complications included bleeding, necrosis, mucocutaneous separation, prolapsed stoma, retraced stoma, stenosis, and hyperplasia; peristomal complications did peristomal varix, peristomal hernia, irritant contact dermatitis, allergic contact dermatitis, maceration, folliculitis, hyperplasia, bacterial infection, candidal infection, malignancy in the peristomal area, mechanical damage and pyoderma gangrenosum. Results: For stomal complications, hyperplasia was most common(9.0%). For peristomal complications, irritant contact dermatitis was developed in 17.4%. Sex and BMI were risk factors for irritant contact dermatitis, hyperplasia, peristomal hernia, flat stoma, and retracted stoma. Conclusion: Teaching for preventing irritant contact dermatitis such as proper pouching and peristomal skin protection, and for comprehensive weight control should be emphasized on self care program for ostomates, while ostomy care nurse should take a careful consideration of preoperative ostomy site marking in female obese patients.

Distal humerus fractures (DHFs) are challenging to treat due to the locally complex osseous and soft tissue anatomy. Adequate exposure of the articular surface of the distal humerus is crucial when performing an anatomical reconstruction of the elbow. Even though "triceps-on" approaches are gaining popularity, one of the most commonly used surgical treatments for DHF is olecranon osteotomy. The incidence of complications related to this approach is unclear. This review was performed to assess the type and frequency of complications that occur with the olecranon osteotomy approach in the treatment of DHF. A literature search was conducted in the PubMed/Medline, Embase, and Cochrane Library digital databases up to February 2020. Only English articles describing complications of olecranon osteotomy in the treatment of DHF were included. Data on patient and surgical characteristics and complications were extracted. Statistical analysis was performed using SPSS. A total of 41 articles describing 1,700 osteotomies were included, and a total of 447 complications were reported. Of these 447 complications, wound infections occurred in 4.2% of osteotomies, of which 1.4% were deep infections and 2.8% were superficial. Problems related with union occurred in 3.7% of osteotomies, 2% of which represented non-union and 1.7% delayed union. The high risk of complications in olecranon osteotomy must be considered in the decision to perform this procedure in the treatment of DHF.
