Estimation of Physiologic Ability and Surgical Stress scoring system for predicting complications following abdominal surgery: A metaanalysis spanning 2004 to 2022

BACKGROUND Postoperative complications remain a paramount concern for surgeons and healthcare practitioners.AIM To present a comprehensive analysis of the Estimation of Physiologic Ability and Surgical Stress(E-PASS)scoring system’s efficacy in predicting postoperative complications following abdominal surgery.METHODS A systematic search of published studies was conducted,yielding 17 studies with pertinent data.Parameters such as preoperative risk score(PRS),surgical stress score(SSS),comprehensive risk score(CRS),postoperative complications,post-operative mortality,and other clinical data were collected for meta-analysis.Forest plots were employed for continuous and binary variables,withχ2 tests assessing heterogeneity(P value).RESULTS Patients experiencing complications after abdominal surgery exhibited significantly higher E-PASS scores compared to those without complications[mean difference and 95%confidence interval(CI)of PRS:0.10(0.05-0.15);SSS:0.04(0.001-0.08);CRS:0.19(0.07-0.31)].Following the exclusion of low-quality studies,results remained valid with no discernible heterogeneity.Subgroup analysis indicated that variations in sample size and age may contribute to hetero-geneity in CRS analysis.Binary variable meta-analysis demonstrated a correlation between high CRS and increased postoperative complication rates[odds ratio(OR)(95%CI):3.01(1.83-4.95)],with a significant association observed between high CRS and postoperative mortality[OR(95%CI):15.49(3.75-64.01)].CONCLUSION In summary,postoperative complications in abdominal surgery,as assessed by the E-PASS scoring system,are consistently linked to elevated PRS,SSS,and CRS scores.High CRS scores emerge as risk factors for heightened morbidity and mortality.This study establishes the accuracy of the E-PASS scoring system in predicting postoperative morbidity and mortality in abdominal surgery,underscoring its potential for widespread adoption in effective risk assessment.

Usefulness of the Surgical Apgar Score to Predict the Occurrence of Major Complications in the Early Post-Operative Period of Major Surgeries: Experience of Two Second-Category Hospitals in Cameroon

Objective: The Surgical Apgar Score (SAS) is a tool for intraoperative stratification of the risk of serious complications in the early postoperative period. It varies from 0 to 10 points divided into three risk categories (0 to 4 high, 5 to 7 moderate, 8 to 10 low). The aim of the study was to evaluate its relevance in predicting the appearance of these complications. Material and methods: This descriptive and analytical study was carried out at the “Laquintinie” Hospital in Douala and at the Central Hospital in Yaounde, Cameroon. The main data were collected on a population of patients over 18 years old and recorded on a survey form. They consisted of variables of main interest and exposure variables. Univariate and multivariate statistical analysis using top-down logistic regression models made it possible to evaluate the association of each variable of main interest and each exposure variable. The association was significant at P Results: Of the 88 patients studied, the SAS was 3 hours. In multivariate, this link persisted only and strongly for the SAS OR (IC) 0.1 (0.1 - 0.2) and p = 000. Conclusion: The study found a specific and powerful link between the SAS score < 4 and the occurrence of complications in the early postoperative period, in favor of its relevance in predicting them.

Surgical techniques to prevent delayed gastric emptying after pancreaticoduodenectomy

Background: Delayed gastric emptying(DGE) is one of the most common complications after pancreaticoduodenectomy(PD). DGE represents impaired gastric motility without significant mechanical obstruction and is associated with an increased length of hospital stay, increased healthcare costs, and a high readmission rate. We reviewed published studies on various technical modifications to reduce the incidence of DGE. Data sources: Studies were identified by searching Pub Med for relevant articles published up to December 2022. The following search terms were used: “pancreaticoduodenectomy”, “pancreaticojejunostomy”, “pancreaticogastrostomy”, “gastric emptying”, “gastroparesis” and “postoperative complications”. The search was limited to English publications. Additional articles were identified by a manual search of references from key articles. Results: In recent years, various surgical procedures and techniques have been explored to reduce the incidence of DGE. Pyloric resection, Billroth II reconstruction, Braun's enteroenterostomy, and antecolic reconstruction may be associated with a decreased incidence of DGE, but more high-powered studies are needed in the future. Neither laparoscopic nor robotic surgery has demonstrated superiority in preventing DGE, and the use of staplers is controversial regarding whether they can reduce the incidence of DGE. Conclusions: Despite many innovations in surgical techniques, there is no surgical procedure that is superior to others to reduce DGE. Further larger prospective randomized studies are needed.

Comparison of Surgical Techniques Used in Treating Acromioclavicular Dislocation in Patients Participating in Sports: A Systematic Review

Introduction: The acromioclavicular joint is a superficial diarthrodial joint that surrounds the medial articular facet of the acromion and the distal portion of the clavicle. Due to its anatomy and biomechanics, it is highly susceptible to trauma and in young men who play contact sports, acromioclavicular dislocation is common. This article aimed to systematically review the literature and compare the surgical techniques used in the treatment of acromioclavicular dislocation in patients who practice sports. Methods: This systematic review was conducted according to the International Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Eligible studies for this systematic review included articles in English or Spanish published between 2013 and 2023, which mention the occurrence of acromioclavicular dislocation during sports practices. Additionally, only studies that addressed the surgical treatment of acromion-clavicular dislocation and contained original data on the topic were included. Results: We found 144 eligible studies after searching the LILACS and PubMed databases. Based on the inclusion and exclusion criteria and the reviewers’ consensus, we selected four studies for the systematic review. 133 patients with AC joint displacement were evaluated. Mean Age: approximately 31.90 years. 81.92 of these injuries occurred during sports practice. Surgical Procedures Used: titanium plates fixation (49 patients), arthroscopy (24), single tunnel technique (30) and coracoid sling technique (30). The results of the visual analog scale and Constant-Murley scores varied between the techniques used. Twenty-two complications after surgical treatment were identified. Conclusion: A significant variability of operative techniques can be used in the surgical approach of acromioclavicular dislocation, such as arthroscopy, single tunnel, coracoid sling and titanium plates. Although it presented excellent functional results compared to the other three techniques evaluated by this review, using titanium plates is not the gold standard since other techniques not assessed by this work may be more effective.

Historical changes in surgical strategy and complication management for hepatic cystic echinococcosis

Echinococcosis is a zoonotic parasitic disease caused by Escherichia larvae.It frequently involves the liver(70%-75%),followed by the lungs(15%-20%),and occasionally the brain,heart,spleen,bone,and other organs.The main pathogenic forms of human echinococcosis currently include cystic echinococcosis(CE)and alveolar echinococcosis(AE).CE is globally distributed,while the distribution of AE is generally restricted to the northern hemisphere.In China,CE accounts for 75%of all echinococcosis cases.With rapid advances in surgical techniques in recent decades,the surgical strategy for CE has changed,especially with the continuous improvement of surgical methods and the expansion of surgical contraindications.To further understand the changes in surgical treatment strategies for hepatic CE,we interpreted and analyzed the existing literature addressing the surgical treatment of hepatic CE both domestically and abroad and briefly summarized them in chronological order.This review aims to provide a deeper understanding of the progress in the surgical treatment of hepatic CE to provide clearer avenues for its clinical diagnosis and treatment.

Impact of the Rapid Recovery Concept on Complications and Patient Quality of Life in the Perioperative Nursing of Robot-Assisted Radical Oesophageal Cancer

Aim: This study evaluates the impact of Enhanced Recovery After Surgery (ERAS) nursing on postoperative complications and quality of life in patients undergoing robot-assisted minimally invasive esophagectomy (RAMIE). Methods: A total of 150 patients who underwent RAMIE from January 2020 to January 2022 at our hospital were randomly assigned to either the observation group or the control group, with 75 patients in each. The control group received standard perioperative management and nursing care, while the observation group was treated with ERAS nursing strategies. Interventions continued until discharge, and outcomes such as postoperative complications, quality of life, and nutritional status were compared between the groups. Results: The observation group exhibited a significantly lower incidence of postoperative adverse reactions compared to the control group (P ionally, all dimension scores of the Short-Form 36 Health Survey (SF-36), including the total score, were higher in the observation group (P < 0.05). Furthermore, the Nutritional Risk Screening (NRS) scores for impaired nutritional status and disease severity, along with the total NRS score, were significantly lower in the observation group compared to the control group (P Conclusion: Implementing ERAS nursing in the perioperative care of patients undergoing RAMIE is associated with reduced postoperative complications and enhanced postoperative quality of life and nutritional status. .

Surgical outcomes of complicated cataract with pediatric trematode granulomatous uveitis

AIM:To describe the clinical characteristics and surgical outcomes of complicated cataract with pediatric trematodal granulomatous uveitis(TGU).METHODS:Patients of cataract with TGU in the membranous(inactive) stage underwent cataract surgery with intraocular lens(IOL) implantation.Preoperative history and ophthalmic examination were conducted for all cases,whereas Schimphlug imaging and corneal topography were done for some patients.Postoperative follow up was done on the 1st,2nd,and 5th postoperative days after surgery.Then,it was done at least at one,three,and six months postoperatively.Intraoperative and postoperative complications and the methods of their management were reported.RESULTS:Twelve eyes of 12 male children were included in this study ranging from 8 to 16y.The mean best corrected Snellen visual acuity(BCVA) was significantly improved from 0.09±0.06 preoperatively to 0.37±0.11 at the final visit 6mo postoperatively(P<0.001).Schimphlug imaging and corneal topography showed flattening of the anterior surface of the inferior cornea.Intraoperative difficulties and complications included the poor dilatability of the drown down pupil,strong posterior synechia between the anterior lens capsule and the iris at the site of the inferior retrocorneal vascularized membrane and hyphema.All cases underwent primary hydrophobic IOL implantation.CONCLUSION:Surgery for this type of cataract is relatively safe and effective.It is associated with some specific difficulties and complications that should be considered during surgery and follow up.

Surgical complications after different therapeutic approaches for locally advanced rectal cancer

BACKGROUND Preoperative radiochemotherapy is widely used in locally advanced rectal cancer.It can improve local control of rectal cancer. However, some researchers believe it increases the incidence of surgical complications. They doubt its safety. Patients with locally advanced rectal cancer receive three different treatments in our hospital, including long-course radiochemotherapy, short-course radiotherapy,and surgery directly. We can compare their differences in postoperative complications.AIM To investigate surgical complications caused by different preoperative radiotherapy regimens.METHODS We retrospectively analyzed 1197 patients admitted between 2008 and 2010 with locally advanced rectal cancer. Three hundred and forty-six patients were treated with preoperative long-course radiochemotherapy(25 × 2 Gy) followed by total mesorectal excision(TME) 6–8 wk later, and 259 patients received short-course radiotherapy(10 × 3 Gy) and subsequently TME 7–10 d later. The remaining 592 patients underwent TME alone without neoadjuvant therapy. According to Clavien–Dindo classification, surgical complications were evaluated for up to 30 d after discharge from hospital.RESULTS There were no deaths in 30 d in all groups after treatment. The majorcomplications were anastomotic leakage and perineal wound complications. The results suggested that both long-course [odds ratio(OR) = 3.624, 95% confidence interval(CI): 1.689–7.775, P = 0.001] and short-course(OR = 5.150, 95%CI:1.828–14.515, P = 0.002) radiotherapy were associated with anastomotic leakage.Temporary ileostomy was a protective factor for anastomotic leakage(OR =6.211, 95%CI: 2.525–15.385, P < 0.001). The severity of anastomotic leakage did not increase in patients following preoperative radiotherapy(P = 0.411).Compared with TME alone, short-course radiotherapy was associated with an increase in perineal wound complications(OR = 5.565, 95%CI: 2.203–14.057, P <0.001), but long-course radiotherapy seemed safe regarding this complication(OR= 1.692, 95%CI: 0.651–4.394, P = 0.280). Although the severity of perineal wound complications increased in patients following short-course radiotherapy(P <0.001), additional intervention was not necessary.CONCLUSION Radiotherapy increased the incidence but not severity of anastomotic leakage.Short-course radiotherapy was also accompanied with perineal wound complications, but intervention appeared unnecessary to ameliorate the complications.

Analysis of surgical and perioperative complications in seventy-five right hepatectomies for living donor liver transplantation

AIM: To present an analysis of the surgical and perioperative complications in a series of seventy- five right hepatectomies for living-donation (RHLD) performed in our center. METHODS: From January 2002 to September 2007, we performed 75 RHLD, defined as removal of a portion of the liver corresponding to Couinaud segments 5-8, in order to obtain a graft for adult to adult living-related liver transplantation (ALRLT). Surgical complications were stratified according to the most recent version of the Clavien classification of postoperative surgical complications. The perioperative period was defined as within 90 d of surgery. RESULTS: No living donor mortality was present in this series, no donor operation was aborted and no donors received any blood transfusion. Twenty- three (30.6%) living donors presented one or more episodes of complication in the perioperative period. Seven patients (9.33%) out of 75 developed biliary complications, which were the most common complications in our series.CONCLUSION: The need to define, categorize and record complications when healthy individuals, such as living donors, undergo a major surgical procedure, such as a right hepatectomy, reflects the need for prompt and detailed reports of complications arising in this particular category of patient. Perioperative complications and post resection liver regeneration are not influenced by anatomic variations or patient demographic.

Comprehensive review of post-liver resection surgical complications and a new universal classification and grading system

Liver resection is the gold standard treatment for certain liver tumors such as hepatocellular carcinoma and metastatic liver tumors. Some patients with such tumors already have reduced liver function due to chronic hepatitis, liver cirrhosis, or chemotherapy-associated steatohepatitis before surgery. Therefore, complications due to poor liver function are inevitable after liver resection. Although the mortality rate of liver resection has been reduced to a few percent in recent case series, its overall morbidity rate is reported to range from 4.1% to 47.7%. The large degree of variation in the post-liver resection morbidity rates reported in previous studies might be due to the lack of consen-sus regarding the definitions and classification of postliver resection complications. The Clavien-Dindo(CD) classification of post-operative complications is widely accepted internationally. However, it is hard to apply to some major post-liver resection complications because the consensus definitions and grading systems for posthepatectomy liver failure and bile leakage established by the International Study Group of Liver Surgery are incompatible with the CD classification. Therefore, a unified classification of post-liver resection complications has to be established to allow comparisons between academic reports.

Prediction of surgical complications in the elderly:Can we improve outcomes?

As the number of Americans aged 65 years and older continues to rise,there is projected to be a corresponding increase in demand for major surgeries within this population.Consequently,it is important to utilize accurate preoperative risk stratification techniques that are applicable to elderly individuals.Currently,commonly used preoperative risk assessments are subjective and often do not account for elderly-specific syndromes that may pose a hazard for geriatric patients if not addressed.Failure to accurately risk-stratify these patients may increase the risk of postoperative complications,morbidity,and mortality.Therefore,we aimed to identify and discuss the more objective and better-validated measurements indicative of poor surgical outcomes in the elderly with special focus on frailty,patient optimization,functional status,and cognitive ability.

Complications of chronic pancreatitis prior to and following surgical treatment:A proposal for classification

BACKGROUND Chronic pancreatitis(CP)is a long-lasting disease frequently associated with complications for which there is no comprehensive pathophysiological classification.AIM The aims of this study were to:Propose a pathophysiological classification of the complications of CP;evaluate their prevalence in a surgical cohort prior to,and following surgical management;and assess the impact of the surgical treatment on the occurrence of new complications of CP during follow-up.We hypothesized that optimal surgical treatment can resolve existing complications and reduce the risk of new complications,with the exclusion of pancreatic insufficiency.The primary outcomes were prevalence of complications of CP at baseline(prior to surgical treatment)and occurrence of new complications during follow-up.METHODS After institutional review board approval,a prospective observational cohort study with long-term follow-up(up to 20.4 years)was conducted.All consecutive single-center adult patients(≥18 years of age)with CP according to the criteria of the American Pancreas Association subjected to surgical management between 1997 and 2021,were included.The prevalence of CP complications evaluated,according to the proposed classification,in a surgical cohort of 166 patients.Development of the pathophysiological classification was based on a literature review on the clinical presentation,course,and complications of CP,as well a review of previous classification systems of CP.RESULTS We distinguished four groups of complications:Pancreatic duct complications peripancreatic complications,pancreatic hemorrhages,and pancreatic insufficiency(exocrine and endocrine).Their baseline prevalence was 20.5%,23.5%,10.2%,31.3%,and 27.1%,respectively.Surgical treatment was highly effective in avoiding new complications in the first and third groups.In the group of peripancreatic complications,the 15-year Kaplan-Meier prevalence of new complications was 12.1%.The prevalence of pancreatic exocrine and endocrine insufficiency increased during follow-up,being 66.4%and 47.1%,respectively,at 15 years following surgery.Pancreatoduodenal resection resulted optimal results in avoiding new peripancreatic complications,but was associated with the highest rate of pancreatic exocrine insufficiency.CONCLUSION The proposed complication classification improves the understanding of CP.It could be beneficial for clinical decision making,as it provides an opportunity for more comprehensive judgement on patient’s needs on the one hand,and on the pros and cons of the treatment under consideration,on the other.The presence of complications of CP and the risk of development of new ones should be among the main determinants of surgical choice.

Comparison of Severe Complications after Acute Stanford Type B Aortic Dissection under Different Surgical Timing

Objective: To investigate the relationship between early intervention timing and complications of acute Stanford type B aortic dissection. Methods: The clinical data of 146 patients with acute stanford type B aortic dissection treated with transseptal stent for aortic endovascular repair (TEVAR) from January 2012 to October 2017 in Xiaogan Central Hospital were analyzed. The time was divided into 3 groups, including the onset to TEVAR time &le;48 h group (41 cases in group A), the onset to TEVAR time 48 h - 7 d group (56 cases in group B), the onset to TEVAR time 7 d - 14 d group (49 cases in group C)). The clinical baseline data, the incidence of different complications during perioperative period, and the mortality rate at 30 days were compared between the three groups. Results: There were no significant differences in age, gender and comorbidities between the three groups (all P > 0.05). Group A had a clearer indication of immediate intervention compared with group B and group C (P P P > 0.05). Conclusion: Early intervention of acute TBAD may increase the risk of serious complications after surgery, and the incidence of serious complications will gradually decrease over time;the reduction of severe complications after early grouping is not accompanied by Early mortality and reoperation rates were significantly reduced, and TEVAR treatment in some patients with dissection did not prevent dissection progression and rupture.

Surgical chest complications after liver transplantation

Liver transplantation is a major abdominal operation and the intimate anatomic relation of the liver with the right hemidiaphragm predisposes the patient to various manifestations in the chest cavity.Furthermore,chronic liver disease affects pulmonary function before and after liver transplantation resulting in a considerable percentage of patients presenting with morbidity related to chest complications.This review aims to identify the potential chest complications of surgical interest during or after liver transplantation.Complications of surgical interest are defined as those conditions that necessitate an invasive procedure(such as thoracocentesis or a chest tube placement)in the chest or a surgical intervention performed by a thoracic surgeon.These complications will be classified as perioperative and postoperative;the latter will be categorized as early and late.Although thoracocentesis or a chest tube placement is usually sufficient when invasive measures are deemed necessary,in some patients,thoracic surgical interventions are warranted.A high index of suspicion is needed to recognize and treat these conditions promptly.A close collaboration between abdominal surgeons,intensive care unit physicians and thoracic surgeons is of paramount importance.

Surgical Complications and Evolution of Grafts in Children with Renal Transplantation at Cayetano Heredia National Hospital

Objective: This study aims to determine surgical complications and graft outcome in children undergoing renal transplantation at Cayetano Heredia National Hospital (CHNH). Materials and Methods: A case study series focused on the incidence of surgical complications and graft outcome in pediatric patients with end stage renal disease (ESRD) who underwent renal transplant (RT) between December 2007 and March 2011. Results: The study described 29 pediatric transplant patients whose average age was 13.69 ± 3.38 (6.2-17.9) years. The etiology of end stage renal disease (ESRD) was renal hypoplasia in 12 patients (41.38%), primary glomerulopathy in 10 patients (34.48%), obstructive uropathy in 4 patients (13.79%), vasculitis in 2 patients (6.9%) and hemolytic uremic syndrome (HUS) in 1 (3.45%) patient. There were 11 surgical complications (34.48%): 2 cases of arterial thrombosis, 3 cases of urinary fistula, 3 of lymphocele, 1 of venous thrombosis, urinoma and perineal collection. The follow-up time was 15.84 ± 12.19 months. Graft survival at 12, 24, and 40 months was 89.29%, 77.16% and 77.16%, respectively. Conclusion: Surgical complications and graft survival in pediatric renal transplantation in our series did not differ from other published series.

Evaluation of Surgical Complications of Mandibulectomy

Mandibulectomy is a surgery that leads to heavy aesthetic and functional sequelae. Surgical complications have been noted but have not yet been evaluated. The aim of this study was to evaluate the surgical complications of mandibulectomy. This is a retrospective descriptive and analytical study of patients who underwent mandibulectomy in the Department of Maxillofacial Surgery of the CHU JDR Befelatanana between January 2017 and December 2020. A correlation between the occurrence of complications, parameters related to the patients and those related to the surgery was sought. Patient-related parameters were: age and sex, comorbidities, toxic habits and body mass index. The parameters related to the surgery which were studied were the duration of the intervention, the size and the seat of the bone defect, the interruption or not of the mandibular continuity. Forty-six cases were selected. The average age was 36.98 years and the sex ratio was 0.7. Fifty percent of patients developed surgical complications. The total number of complications was 38. Salivary fistula was the most frequent complication (26.32%). No correlation was found between the occurrence of complications and patient-related parameters. There were 69.57% of complications when the procedure lasted more than 180 minutes (p = 0.003). A correlation was found between the occurrence of complications and the size of the resected bone (p = 0.009). Among the complications, 56.52% occurred when the size exceeded 130 mm (p = 0.03). The complication rate is high. The size of the resected bone and the duration of the operation influence the occurrence of complications.

Associations between SARS-CoV-2 infections and thrombotic complications necessitating surgical intervention:A systematic review

BACKGROUND Several unique clinical features of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),the cause of coronavirus disease 2019(COVID-19)infection,have been identified and characterized.One such feature,mostly among patients with severe COVID-19 infection,has become known as COVID-19-induced coagulopathy.Surgical patients with a history of or active COVID-19 infection bear a significantly higher risk for postoperative thrombotic complications.These patients may require surgical intervention to treat severe thrombotic complications.Few studies have been carried out to better characterize this association.The purpose of this study was to perform a systematic review and meta-analysis of the literature on COVID-19 infections that led to thrombotic complications necessitating surgical intervention.We hypothesized that patients with recent or active COVID-19 infection would have high rates of thromboembolic complications both arterial and venous in origin.AIM To perform a systematic review and meta-analysis of the literature on COVID-19 infections that led to thrombotic complications necessitating surgical intervention.METHODS The current systematic review implemented an algorithmic approach to review all the currently available English medical literature on surgical interventions necessitated by COVID-19 thrombotic complications using the preferred reporting items for systematic reviews and metaanalysis principles.A comprehensive search of the medical literature in the“PubMed”,“Scopus”,“Google Scholar”top 100 results,and archives of Plastic and Reconstructive Surgery was performed using the key words“COVID-19”AND“surgery”AND“thromboembolism”AND“complication”.The search string was generated and the records which were not specific about surgical interventions or thrombotic complications due to COVID-19 infection were excluded.Titles and abstracts were screened by two authors and full-text articles were assessed for eligibility and inclusion.Finally,results were further refined to focus on articles that focused on surgical interventions that were necessitated by COVID-19 thrombotic complications.RESULTS The database search resulted in the final inclusion of 22 retrospective studies,after application of the inclusion/exclusion criteria.Of the included studies,17 were single case reports,3 were case series and 2 were cross sectional cohort studies.All studies were retrospective in nature.Twelve of the reported studies were conducted in the United States of America,with the remaining studies originating from Italy,Turkey,Pakistan,France,Serbia,and Germany.All cases reported in our study were laboratory confirmed SARS-CoV-2 positive.A total of 70 cases involving surgical intervention were isolated from the 22 studies included in this review.CONCLUSION There is paucity of data describing the relationship between COVID-19 infection and thrombotic complications necessitating the need for surgical intervention.Intestinal ischemia and acute limb ischemia are amongst the most common thrombotic events due to COVID-19 that required operative management.An overall postoperative mortality of 30%was found in those who underwent operative procedures for thrombotic complications,with most deaths occurring in those with bowel ischemia.Physicians should be aware that despite thromboprophylaxis,severe thrombotic complications can still occur in this patient population,however,surgical intervention results in relatively low mortality apart from cases of ischemic bowel resection.

Complications of Surgical Treatment of Anterior Shoulder Dislocation:A Systematic Review

Introduction: shoulder joint has the greatest range of motion in the human body. The shoulder anatomy promotes high mobility and favors relative sacrifice of articular stability, making it susceptible and more prone to events of instability and dislocation. This review aimed at identifying main complications of surgical treatment of anterior shoulder dislocation. Methodology: This systematic review was conducted according to the International Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) guidelines. Studies which were eligible for this systematic review included: English or Spanish language, studies published from 2000, which mentioned surgical complications of anterior shoulder dislocation in their results, both in open and arthroscopic surgery. Included studies which were required to have at least 1 complication following surgical repair. Only studies from original data were included. Results: We found 228 potentially eligible studies for the survey. Through the inclusion and exclusion criteria and after consensus among reviewers, we chose 9 studies to compose the systematic review. Conclusion: Important information emerges: recurring instability, recurring dislocation, external rotation limitation and arthritis are main surgical complications of anterior shoulder dislocation.

Long-term complications of the transmeatal approach (Open Transcanal) in cochlear implants: A follow-up study

Objective: Multiple alternative approaches of cochlear implant surgery have been described, such as the suprameatal approach, transcanal approach, transmeatal approach and middle cranial fossa approach.Transmeatal(open trnascanal) approach has not been adapted since first described in the clinical field.we aimed to assess the long-term complications of the transmeatal approach in a series of 131 patients at our center between 2004 and 2008.Methods: This study was a retrospective case series of all patients who underwent cochlear implants with the transmeatal(open transcanal) approach from May 2004 to December 2008 at King Faisal Specialist and Research Hospital(Riyadh, Saudi Arabia), which were conducted by the same surgeon.Results: Complications were observed often with various combinations-recurrent otitis externa, posterior tympanic membrane perforation, electrode extrusion, cholesteatoma, and chronic mastoiditis. The overall long-term complication rate was 16%(21/131). The gap between the implantation and the diagnosis of a complication ranged from <1 year to 11 years. Major complications were as follows:cholesteatoma in 5(3.8%) patients, extrusion of the electrode in 5(3.8%) patients, and tympanic membrane perforation or deep retractions in 5(3.8%) patients. Minor complications were as follows: recurrent mastoiditis with/without concomitant temporary facial nerve palsy in 4(3%) patients, recurrent otitis externa infections in 7(5%) patients, and weakness of the posterior canal wall in 1 patient.Conclusion: The transmeatal approach posed an high rate of complications on long-term follow-up such as cholestetoma formation, extrusion of electrode or perielectrode reaction formation to tympanic membrane and external auditory canal.

Predisposing factors and surgical outcome of complicated liver hydatid cysts

AIM: To evaluate the predisposing factors for peritoneal perforation and intrabiliary rupture and the effects of these complications on surgical outcome in liver hydatid disease.METHODS: A total of 372 patients with liver hydatid cysts who had undergone surgical treatment were evaluated retrospectively. Twenty eight patients with peritoneal perforation, 93 patients with spontaneous intrabiliary perforation, and 251 patients with noncomplicated hydatid cysts were treated in our clinics.RESULTS: When the predisposing factors for complications were evaluated, younger age, superf icial position, and larger cyst dimensions (P < 0.05; range, 0.0010.017) increased peritoneal perforation rates. It was shown that older age increased cyst dimensions, and presence of multiple and bilobar cysts increased intrabiliary rupture rates (P < 0.05; range, 0.0010.028). Partial pericystectomy and drainage was the most frequent surgical procedure in all groups (71.6%). The incidence of postoperative complications in the peritoneal perforated group, in the intrabiliary ruptured group, and in the noncomplicated group was 25%, 16.1% and 5.5%, respectively. When compared, complication rates were significantly different (P = 0.002). When length of hospital stay was compared, there was no signif icant difference between the groups (P > 0.05). The overall recurrence rate was 3.8% (14 patients), but there was not any statistical difference among the patient groups (P = 0.13). The early postoperative mortality rate was 1.1%. CONCLUSION: In peritoneally perforated and intrabiliary ruptured cases, the most important steps are irrigation of the peritoneal cavity and clearance of the cystic material from the biliary tree.
