The analysis of injuries, life-threatening consequences and outcomes of treatment of wounded with penetrating chest wounds and the results of approbation of a prototype (medical) disposable set UD-02v for the elimination of strained and open pneumothorax, hemothorax, pleural drainage and collection of spilled blood with the possibility of subsequent reinfusion at the pre-hospital stage is presented. The prototype of the UD-02v set was created as part of the implementation of the state defense order in 2018. Its creation is due to the fact that despite the improvement of medical care at the stages of medical evacuation and the widespread use of individual armor protection, chest injuries currently remain a frequent type of combat surgical injury, accounting for 6 to 12% of all injuries. The main cause of death of injured and injured with chest injuries remains blood loss caused by continuing intrapleural bleeding and concomitant damage to other anatomical areas. Stressful pneumothorax, together with intrapleural bleeding, account for 93% of preventable causes of fatal chest injuries at the pre-hospital stage. Untimely elimination of the consequences of severe breast injuries should be considered as a negative factor affecting the outcome of treatment, and significant improvement in treatment results should be expected only in the case of early elimination of the most severe consequences of breast injuries. The developed set of UD-02v exceeds foreign medical devices in its medical and technical characteristics, and is the most promising for acceptance for the supply of the Armed forces of the Russian Federation as part of the samples of complete and service equipment.

Treatment of acute pancreatitis and infectious complications is a complex multidisciplinary task. The use of traditional surgical procedures for the rehabilitation of foci of pancreatogenic infection often aggravates the course of the disease, leads to the development of postoperative complications, does not improve the results of treatment. On the contrary, the use of minimally invasive techniques avoids additional surgical injury. The case of stage treatment of acute pancreatitis and its purulent-septic complications with the use of minimally invasive technologies is presented to the readers.

It is possible that in the setting of increasing patient comorbidity and obesity, risk for surgical injury and need for reoperation is increasing. It is also possible that with differential uptake of evidence-based recommendations and increasing prevalence of risk factors such as obesity, risk for surgical site complications is increasing. The objective of this study was to evaluate trends in, risk factors for, and racial disparities related to cesarean complications. This repeated cross-sectional study evaluated cesarean deliveries in the 2002–2014 National Inpatient Sample for women age 15–54. The primary outcome was a cesarean surgical complication composite including (i) surgical injuries, (ii) reoperation, and (iii) surgical site complications. Surgical injuries, reoperation, and surgical site complications were additionally evaluated individually as outcomes. Univariable and multivariable log linear regression models including demographic, clinical, and hospital factors were performed to assess risk for outcomes with unadjusted and adjusted risk ratios (aRR) with 95% confidence intervals (CI) as measures of association. Temporal trends were estimated using average annual percentage change from a joinpoint regression model. A stratified analysis was performed restricted to non-Hispanic black women. Data was weighted to provide national estimates. A total of 16.2 million estimated cesarean deliveries (3.2 million unweighted cesarean deliveries) from 2002 to 2014 were included in this analysis. The prevalence of the cesarean surgical complication composite was 1.14%, surgical site complications occurred in 0.60%, surgical injuries in 0.49%, and reoperations in 0.10%. Comparing the end of the study (2012–2014) to the beginning of the study (2002–2003), adjusted risk for the composite was similar (aRR 0.93, 95% CI 0.92, 0.95). In comparison, surgical site complication risk was lower at the end of the study (aRR 0.77, 95% CI 0.75, 0.79) while risks for surgical injury (aRR 1.18, 95% CI 1.15, 1.22) and reoperation (1.18, 95% CI 1.10, 1.26) were higher. Non-Hispanic black women were at increased risk for surgical site complications (aRR 1.83, 95% CI 1.80, 1.87) and reoperation (aRR 1.44, 95% CI 1.37, 1.51), but not surgical injury (aRR 0.99, 95% CI 0.97, 1.02). In analyses stratified for non-Hispanic black women, there was a reduction in risk for surgical site complications at the end of the study period compared to the beginning similar to the primary analysis (aRR 0.76, 95% 0.72, 0.81) with a modest decrease in overall risk for the composite outcome (aRR 0.85, 95% CI 0.81, 0.89). A decrease in risk for surgical site complications was offset by slightly increased risk for surgical injury and reoperation in adjusted analyses. Among non-Hispanic black women, surgical site complication risk decreased proportionately with this group still at significantly higher overall risk.

Introduction: Enhanced Recovery After Surgery (ERAS) protocol is a perioperative multimodal service program designed to achieve a faster surgical recovery period and a better outcome, the key in reducing morbidity in surgery is by reducing the “surgical injury” and reducing the body’s stress response caused by the surgery. The success of the ERAS protocol depends on the interpretation and collaboration of the multidisciplinary team, therefore though the protocol is carried out in a hospital that has sufficient facilities and resources, the obstacle in the implementation of ERAS can still happen. The implementation of ERAS protocol in the non-permanent hospital service facility becomes a challenge in itself. Case Reports: From the two case reports of the implementation of ERAS protocol in the Ksatria Airlangga Floating Hospital (RST-KA) it is obtained that the key success of the anesthesia in ERAS protocol above lies on the administration of opioid-sparring therapy where it will reduce the use of opioid. Although there are many obstacles obtained in the RST-KA, the use of ERAS protocol can be conducted by making effective use of opioid-sparring combined with the administration of multimodal analgesia. Conclusion: Therefore, it can be concluded that the ERAS protocol can be applied in the social service concept in the non-permanent health facility.

Serum anti-Müllerian hormone (AMH) levels decrease after surgical treatment of ovarian endometrioma. This is the main reason that surgery for ovarian endometrioma endometriosis is not recommended before in vitro fertilization, unless the patient has severe pain or suspected malignant cysts. Furthermore, it has been suggested that ovarian endometrioma itself damages ovarian reserve. This raises two important challenges: (1) determining how to prevent surgical damage to the ovarian reserve in women with ovarian endometrioma and severe pain requiring surgical treatment and (2) deciding the best treatment for women with ovarian endometrioma without pain, who do not wish to conceive immediately. The mechanisms underlying the decline in ovarian reserve are potentially induced by both ovarian endometrioma and surgical injury but the relative contribution of each process has not been determined. Data obtained from various animal models and human studies suggest that hyperactivation of dormant primordial follicles caused by the local microenvironment of ovarian endometrioma (mechanical and/or chemical cues) is the main factor responsible for the decreased primordial follicle numbers in women with ovarian endometrioma. However, surgical injury also induces hyperactivation of dormant primordial follicles, which may further reduce ovarian reserve after removal of the endometriosis. Although further studies are required to elucidate the mechanisms underlying diminished ovarian reserve in women with ovarian endometrioma, the available data strongly suggests the need to prevent/minimize hyperactivation of dormant primordial follicles, regardless of whether surgery is performed, for better clinical management of ovarian endometrioma.

Objective This quality improvement (QI) initiative was designed to identify gaps between evidence-based or hospital recommendations for trial of labour after cesarean delivery (TOLAC) labour management and clinical practice. Methods Viable, singleton pregnancies from January 1, 2016, to December 31, 2018, undergoing TOLAC were extracted from the electronic medical record. Sixty randomly selected charts were reviewed for (1) consent, (2) induction methods, (3) oxytocin use, (4) continuous fetal monitoring, (5) admission indication, (6) examination regularity, (7) duration of dystocia before decision to perform cesarean delivery (CD), and (8) maternal complications. Results The institutional vaginal birth after cesarean rate was 71%. Documented consent to TOLAC on admission was present in 50% of cases. Oxytocin augmentation was used in 38% of cases, and the median maximum dose was 4 mU/min (interquartile range [IQR] 3–7.5 mU/min). Delays in initiating oxytocin were identified in 47% of those patients. Decisions to deliver by cesarean were made after a median time of 5 hours and 40 minutes (IQR 3 hours and 30 minutes to 6 hours and 35 minutes) of failure to progress despite adequate contractions. After this decision, median time to delivery was 1 hour and 11 minutes (IQR 57 minutes to 2 hours and 16 minutes). Complications included postpartum hemorrhage (5%) and chorioamnionitis (6.7%). Surgical injury occurred in 10% of intrapartum CD. Peripartum complications were associated with delay in oxytocin implementation (χ2 (1) = 9.80; P Conclusion Areas for QI were identified in (1) consent, (2) duration of dystocia before decision to proceed with CD and delay to CD, and (3) peripartum complications. We recognize the potential use of this as a tool to identify areas for QI and prospective study.

Purpose: To report our findings in a case of bilateral Mooren's ulcer that developed after filtering surgeries using the EX-PRESS glaucoma filtering device (EX-PRESS surgery). Patients and methods: A 71-year-old Japanese man with primary open angle glaucoma underwent EX-PRESS surgery first in his left eye and 1 month later in his right eye. He developed Mooren's ulcer in his right eye at 7 months and in his left eye at 10 months after the initial EX-PRESS surgery. Systemic examinations showed no collagen vascular disease, and he did not have a history of bacterial or viral infections. He was not allergic to metallic materials. Before the EX-PRESS surgery, he had underdone cataract surgery combined with trabeculotomy in both eyes, and a reoperation of trabeculotomy in his left eye. He had not developed Mooren's ulcer after these surgeries. The Mooren's ulcer after the EX-PRESS surgery was treated with oral prednisolone (30 mg tapering) in combination with topical 0.1% betamethasone sodium. The ulcers were responsive and healed well in three months. Conclusions: The EX-PRESS devices were most likely the cause of the Mooren's ulcers considering that they were located close to the site of EX-PRESS insertion and no peripheral corneal ulcer developed after prior intraocular surgeries.

Objective To determine the effect of alveolar decortication on orthodontically induced root resorption. Materials and Methods A total of 24 male Wistar rats (14 week old) were used. The rats were randomly divided into one of the following three groups: group 1 (control group), orthodontic tooth movement (OTM) for 2 weeks; group 2, OTM for 2 weeks + two alveolar decortications (2AD); group 3, OTM for 2 weeks + four alveolar decortications (4AD). The first molar was moved mesially for 2 weeks. Micro computed tomography was used to analyze root volume. In addition, histological sections were stained with Tartrate Resistant Acid Phosphatase (TRAP) to quantify the osteoclast number. Results The buccal root volume in OTM + 4AD group was decreased by 8.92% and 6.11% when compared with the OTM-only group and OTM + 2AD group, respectively. Similarly, the other four root volumes in the OTM + 4AD group was decreased by 8.99% and 5.24% when compared with the OTM-only group and OTM + 2AD group, respectively. There was a decrease in buccal root density in the OTM + 4AD group by 4.66% and 3.56% when compared with the OTM-only group and the OTM + 2AD group, respectively. In addition, there was an increase in the number of osteoclasts by 195.73% and 98.74% in OTM + 4AD group in comparison with the OTM and OTM + 2AD group. Conclusions The amount of orthodontically induced root resorption was positively correlated with the extent of surgical injury used to accelerate orthodontic tooth movement.

Background. Gynecomastia is one of the most famous and common paraneoplastic syndromes. With the growth of equipment clinics with modern diagnostic equipment, including the CT, increases the detection of breast pathology in men. There is the need for a correct interpretation of the data about the state of male breast by radiologists, and the attending physician, oncologist, mammologist, urologist, endocrinologist. The purpose of the study to identify possible differences in frequency and radiation pattern of gynecomastia in patients with cancer and without it and also to follow the dynamics of the development of gynecomastia in patients with cancer, to identify the probable causes of the progression of gynecomastia in patients with cancer. Materials and methods. It's data of 400 chest CT of men who were screened and treated for the different oncological pathology in Voronezh regional clinical oncological hospital in 2013-2015. And also data of 150 chest CT of men who were screened and treated for the various diseases (excluding oncological diseases) in the Voronezh regional clinical diagnostic center and Kursk regional clinical hospital in 2013-2015 was used. Results. The data of the frequency of occurrence various types of gynecomastia in patients with cancer pathology and without it was obtained. The frequency of occurrence of gynecomastia in patients with cancer depending on the localization and morphology of tumor was analyzed. The dynamics of the gynecomastia in patients with cancer was tracked and possible causes of its progression in patients in this group were identified. Conclusions 1. Gynecomastia is a frequent pathology revealed by chest CT in men as suffering from oncological disease and without it. Gynecomastia significantly more often found in patients suffering from prostate adenocarcinoma and renal cell carcinoma. Surgical injury may be one of the reasons for the development of gynecomastia. Feature of gynecomastia in patients with cancer is its asymmetry. When the detection of asymmetrical gynecomastia by chest CT is recommend the further examination of patient to exclude him cancer pathology, special attention should be paid to the prostate gland and the kidneys. Upon detection of the progression of gynecomastia in a patient with a history of cancer need further examination to exclude cancer pathology progression.

Benign biliary strictures (BBSs) are commonly caused by surgical injury, chronic pancreatitis, and inflammatory cholangiopathies. Although advanced imaging tests and tissue acquisition methods have been developed for evaluation of indeterminate biliary strictures, differentiation of BBSs from biliary malignancies remains a challenge to clinicians. The majority of BBSs have good response to nonsurgical treatment and surgical intervention mainly serves as a rescue when nonsurgical approaches fail. Endoscopic management is a safe, effective, and less-invasive treatment for BBSs compared with other approaches. Endoscopic biliary stricture dilation followed by placement of multiple plastic stents has been the first-line choice with good long-term ductal patency. Recently, covered self-expanding metal stents (CSEMSs) has been increasingly used in the management of BBSs with similar effectiveness but easier deployment, fewer endoscopic sessions compared with plastic stents. Moreover, other technologies are emerging in the diagnosis and management of BBSs. To assist clinicians in managing BBSs, the Asia-Pacific ERCP Club (APEC) has developed this statement through a systematic review of the literature.

The neurotoxicity of general anesthetic drugs still appears as a relevant interdisciplinary problem. All general anesthetics that are currently in use exhibit a neurotoxic effect on the brain at all stages of its development. It is impossible to evaluate the negative impact of general anesthetics without considering the effect of surgical injury, intraoperative complications, pain syndrome, main and concomitant diseases. We report a case of hypoxic brain injury in the early postoperative period in a child with severe comorbidities and perinatal complications in anamnesis.

Purpose: To establish determining factors for fast corneal sensitivity (CS) recovery after pterygium excision. Methods: Thirty-two eyes of 14 males and 18 females with primary nasal pterygium were recruited. Differences in CS (in the 4 quadrants and the center using a Cochet–Bonnet esthesiometer), pterygium corneal area (PCA), tear osmolarity, tear break-up time, Schirmer test, and ocular symptoms were analyzed before and 1 month after lesion excision. The relationship between CS recovery (difference between the 2 time points; CS1 – CS0) and the other features was assessed. Results: All the studied locations exhibited normal (6 cm) or near-normal mean CS at the 2 time points, except a tendency for moderate hypoesthesia in nasal CS0 (median 4.5; range: 1.5–6.0 cm). Point by point comparison revealed significant postoperative improvements in nasal location (P = 0.008; Wilcoxon signed-rank test) with normal values in 17 eyes (53%) and a median CS1 = 5.0 cm (2.5–5.5 cm) in 15 eyes with no complete recovery. No significant correlation was found between CS0 and the studied variables, and CS1 was only significantly correlated with PCA (rho: -0.441; P < 0.05). CS recovery also showed significant correlation with PCA (rho = -0.516; P < 0.01). Conclusions: CS recovery after pterygium excision showed important variability, and the only studied factor that seems to be determinant could be PCA. It would be advisable to operate when the lesion is relatively small, with lower surgical injury and faster and complete recovery, thus protecting ocular surface homeostasis.

Typical etiologies of vesicovaginal fistula (VVF) include obstructed labor, iatrogenic surgical injury, pelvic irradiation and cancer invasion. VVF caused by cystocele are very rare. To date, there are no documented cases in Japanese literature.A 74-year-old woman presented with near total incontinence. On physical examination, she was found to have severe cystocele and pressure necrosis of anterior vaginal wall, which caused partial breakdown of vaginal mucosa and VVF. She underwent vesicovaginal fistula repair using transvaginal and transabdominal approaches. Catheter drainage was performed for 10 days and postoperative cystogram showed no sign of leakage. She is currently symptom-free at 55 months.

Oxytocin augmentation was used in 38% of cases and the median max dose was 4 [IQR 3-7.5] mU/min. Delays in initiating oxytocin were identified in 47% of those patients. Decisions to deliver by CS were made after a median time of 5h 40 min [IQR 3h 30m – 6h35m] of failure to progress despite adequate contractions. After this decision, median time to delivery was 1h 11m [IQR 57m–2h 16m]. Complications included post-partum hemorrhage (5%) and chorioamnionitis (6.7%). Surgical injury occurred in 10% of intrapartum CS. Peri-partum complications were associated with delay in oxytocin implementation ((1) = 9.80, p Conclusions Areas for QI were identified in 1) consent, 2) duration of dystocia prior to decision for CS and delay to CS delivery, 3) peri-partum complications. We recognize the potential use of this as a tool to identify areas for QI and prospective study.

Background: Although pleurodesis is usually used to reduce the recurrence rate for primary spontaneous pneumothorax (PSP) in surgery, existing techniques cannot meet the higher requirements of little surgical injury and less relapse. Hence, we developed a new pleurodesis technique and named multipoint pleura cautery. Aim: In this study, we aimed to investigate the effectiveness and outcomes of the uniportal video-assisted thoracoscopic surgery C-shaped pleura cautery in the surgical treatment of PSP. To the best of our knowledge, this is a new surgical technique for pleurodesis and must be of concern. Patients and Methods: The medical records of 20 patients undergoing surgery for C-shaped pleura cautery between 2015 and 2017 were reviewed. The patients were evaluated with regard to age, gender, body mass index, smoking habit, operation time, duration of hospitalization, post-operative pain and follow-up. Results: We have performed a bullectomy combined C-shaped pleura cautery for 20 patients with PSP from January 2016 to December 2017. None of the patients suffered post-operative bleeding and haematothorax complications, and one was ipsilateral relapsed 5 months after surgery. The lung computed tomography showed that recurrence of pneumothorax was due to air leakage in the right lower lung, and there was no air leakage at the site where pleurodesis had been performed. Conclusions: Although this technique requires further investigation, it may be a useful method of pleurodesis.

Jan Máca,1 Matúš Peteja,2 Petr Reimer,1 Ondřej Jor,1 Věra Šeděnková,1 Lucie Panáčková,1 Peter Ihnát,2 Michal Burda,3 Pavel Ševčík1 1Department of Anesthesiology and Intensive Care Medicine, University Hospital Ostrava, Ostrava, Czech Republic; 2The Clinic of Surgery, University Hospital Ostrava, Ostrava, Czech Republic; 3Institute for Research and Applications of Fuzzy Modeling, Centre of Excellence IT4Innovations, University of Ostrava, Ostrava, Czech Republic Background: Major abdominal surgery (MAS) is high-risk intervention usually accompanied by tissue injury leading to a release of signaling danger molecules called alarmins. This study evaluates the surgical injury caused by two fundamental types of gastrointestinal surgical procedures (open surgery and laparoscopy) in relation to the inflammation elicited by alarmins. Patients and methods: Patients undergoing MAS were divided into a mixed laparoscopy group (LPS) and an open surgery group (LPT). Serum levels of alarmins (S100A8, S100A12, HMGB1, and HSP70) and biomarkers (leukocytes, C-reactive protein [CRP], and interleukin-6 [IL-6]) were analyzed between the groups. The secondary objectives were to compare LPT and LPS cancer subgroups and to find the relationship between procedure and outcome (intensive care unit length of stay [ICU-LOS] and hospital length of stay [H-LOS]). Results: A total of 82 patients were analyzed. No significant difference was found in alarmin levels between the mixed LPS and LPT groups. IL-6 was higher in the LPS group on day 2 (p=0.03) and day 3 (p=0.04). Significantly higher S100A8 protein levels on day 1 (p=0.02) and day 2 (p=0.01) and higher S100A12 protein levels on day 2 (p=0.03) were obtained in the LPS cancer subgroup. ICU-LOS and H-LOS were longer in the LPS cancer subgroup. Conclusion: The degree of surgical injury elicited by open MAS as reflected by alarmins is similar to that of laparoscopic procedures. Nevertheless, an early biomarker of inflammation (IL-6) was higher in the laparoscopy group, suggesting a greater inflammatory response. Moreover, the levels of S100A8 and S100A12 were higher with a longer ICU-LOS and H-LOS in the LPS cancer subgroup.

Supraspinatus tears often result in the setting of chronic tendinopathy. However, the typical repair model utilizes an acute injury. In recognition of that distinction, our laboratory developed an overuse animal model; however it is unclear whether induced overuse is necessary in the repair model. We studied the repair properties of overuse-induced tendons compared to normal tendons. We hypothesized that histological and mechanical properties would not be altered between the overuse-induced and normal tendons 1 and 4 weeks after repair. Thirty-one adult male Sprague-Dawley rats were subjected to either overuse or cage activity for 4 weeks prior to bilateral supraspinatus tendon repair surgery. Rats were sacrificed at 1 and 4 weeks post-surgery and evaluated for histology and mechanics. Results at 1 week showed no clear histologic changes, but increased inflammatory protein expression in overuse tendons. At 4 weeks, percent relaxation was slightly increased in the overuse group. No other alterations in mechanics or histology were observed. Our results suggest that the effects of the surgical injury overshadow the changes evoked by overuse. Because clinically relevant mechanical parameters were not altered in the overuse group, we conclude that when examining tendons 4 weeks after repair in the classic rat supraspinatus model, inducing overuse prior to surgery is likely to be unnecessary.

Fifteen years ago, laparoscopic surgery of rectal cancer was considered as radical in terms of oncology as open surgery. A trend to reduce surgical injury may be observed in surgery in recent years. In this paper the first experience in the new minimally invasive method of anterior rectal resection is described – through the transanal way. The procedure duration was 130 min. The use of transanal access in rectal cancer surgery is undoubtedly an alternative method to standard laparoscopic surgery. In patients with a large tumour in the lower rectum, the technique allows a longer rectal stump to be left below the resection border.

Adhesion of freely moving tissues and organs due to surgical injury and trauma can be a serious postoperative complication. High rates of incidence due to surgical intervention, especially associated with abdominal procedures, have been reported. This chapter gives an introduction to the formation of adhesions, with particular focus on peritoneum, urinary and reproductive (female) systems, tendon, ligament, joint, and pericardium. A number of techniques, treatments, and materials have been proposed for the prevention/reduction of adhesion formation. Of these, barrier methods are considered the only effective method currently available. An overview of biomaterials currently used as barriers for postsurgical tissue adhesion is presented. Current clinical practice utilizes solid membranes/mechanical barriers, spray-on, and gel and liquid barriers. These barriers can be either resorbable, nonresorbable, or a combination of both. Complications of barrier films are examined, and design criteria for barrier membranes are presented. Adhesion formation can be beneficial in particular circumstances, such as for anchoring implants, and these uses are commented upon. Much advancement has been made in this area, thanks to the increasing knowledge and understanding regarding the events that control adhesion formation, but there is still a long way to go before an optimum solution to this problem is found.

Facial synkinesis is the simultaneous contraction of the certain facial musculature accompanying a motion of designated muscle in the face. With the exception of rare afflictions that are congenital in origin, most patients develop as a sequel to facial nerve paralysis due to trauma, tumor, and surgical injury. As an idiopathic congenital form, oculo-nasal synkinesis which reveals co-contraction of orbicularis oculi and the compressor narium minor muscles which are innervated by separate branches of the facial nerve have been already reported. In addition to oculo-nasal synkinesis, the authors describe 2 more rare patients with facial synkinesis; oculo-zygomatic and fronto-nasal synkinesis with video documentation, which to the best of our knowledge, have not been reported previously in detail. This will help plastic surgeons prevent being involved in legal issues when they might neglect these rare phenomena in preoperative evaluation during cosmetic surgery.

Sepsis following surgical injury remains a growing and worrisome problem following both emergent and elective surgery. Although early resuscitation efforts and prompt antibiotic therapy have improved outcomes in the first 24 to 48 h, late onset sepsis is now the most common cause of death in modern intensive care units. This time shift may be, in part, a result of prolonged exposure of the host to the stressors of critical illness which, over time, erode the health promoting intestinal microbiota and allow for virulent pathogens to predominate. Colonizing pathogens can then subvert the immune system and contribute to the deterioration of the host response. Here, we posit that novel approaches integrating the molecular, ecological, and evolutionary dynamics of the evolving gut microbiome/pathobiome during critical illness are needed to understand and prevent the late onset sepsis that develops following prolonged critical illness.

A pseudoaneurysm (false aneurysm) develops when all three walls of an artery (intima, media, and adventitia) are violated. In the sellar region, pseudoaneurysms of the internal carotid artery (ICA) usually occur iatrogenically as a result of surgical injury.

Minimally invasive surgery (MIS) was initially used for the treatment of colorectal benign disease. However, the indications for MIS techniques have progressively been expanded to include cancers. Nowadays, the indications for MIS are almost the same as those for open surgery. The scientific validation of MIS for colorectal cancer has favorably evolved. The advantages awaited for the short-term outcome were confirmed, although at the cost of longer operating time and higher costs. In parallel, tangible evidence of oncologic safety was demonstrated, and long-term results of MIS have been found comparable to those of open surgery. In the current state of MIS short-term superiority and log-term equality, less surgical injury, lower immune function depression and better postoperative outcome make MIS particularly suitable for delicate and difficult patients, such as elderly or obese; on the contrary, the lower costs have led to still consider open surgery as a valid alternative for low-impact resections (such as right colectomy). The continuous development in the field of MIS has recently led to the introduction of the single-port (SILS) and natural-orifice (NOTES) techniques, which allow better esthetic results, even if the their validation has not yet reached scientific evidence.

The treatment of relatively large cerebral aneurysms by direct clipping has been reported to significantly increase operative morbidity. In this article, we introduce a newly conducted surgical technique of aneurysmoplasty, which is most suitable for clipping of these ruptured aneurysms and implies additional methods to prevent surgical injury to surrounding vessels and brain tissues. The main concept of aneurysmoplasty includes tentative clipping in the early stage of aneurysm dissection and reduction in size of aneurysms by low output bipolar-coagulation. These methods are systemically arranged and titrated according to the aneurysm’s size and location. Transforming large ruptured aneurysms to small unruptured aneurysms apparently improves safety and reliability in clipping procedure by direct inspection around the neck and behind the dome of aneurysms.

Rationale: A 35-year old Chinese female was admitted to hospital with refractory pericardial effusions 10 days post mitral valve replacement via median sternotomy. We performed an exploratory resternotomy and found lymphatic leakage on the surface of the diaphragm which was continuously emitting a light yellow fluid. Patient concerns: The patient complained of no obvious discomfort except for the concern of massive pericardial effusion drainage. Diagnoses: Exploratory resternotomy and biochemical testing lead to a supradiaphragmatic lymphatic fistula being diagnosed as the cause of the refractory pericardial effusion. Interventions: The fistula was closed with a continuous suture and no other fistulas were found after a thorough exploration. Outcomes: The patient was discharged home on postoperative day 5 and recovery was uneventful. Lessons: In this case a timely exploratory resternotomy proved effective in seeking the cause of and treating pericardial effusion following cardiac surgery.

Disturbed flow patterns, material mismatch, and surgical injury are often cited as being significant contributors to failure at the distal end of femoropopliteal bypass grafts. The objective of this research is to propose a novel bypass graft design concept which seeks to reduce the incidence of disturbed flow in the bypass junction and to establish the surgical feasibility of the proposed device. A preliminary evaluation of the hemodynamic benefit associated with the proposed device was made using computational fluid dynamics. A prototype of the device was then constructed from commercially available materials, and it was prepared for implantation into the aorta of a pig. The computational model of the proposed device showed that significant flow correction was occurring in the in vitro model due to the geometric configuration of the design. The magnitude of the peak wall shear stress in the recirculation region was noted to decrease by 78%. Surgical feasibility of the proposed device was verified by successful implantation into the aorta of the pig. The pig was sacrificed after 7 weeks, the graft and host artery were excised, and histological examination downstream from the distal junction showed that intimal hyperplasia had developed in the host artery. The proposed device is surgically feasible and may offer a significant hemodynamic advantage over current graft designs.

Background. The precise incidence and cause of atrioventricular block (AVB) after heart transplantation remain uncertain. Methods and Results. After surgery, immediate and follow-up electrocardiograms from 1,047 consecutive patients who underwent heart transplantation were reviewed for AVB and correlated with clinical symptoms, laboratory data, rejection grade, and echocardiogram and coronary angiography findings. A total of 113 patients demonstrated various kinds of AVB; the incidence was 10.8%. First-degree AVB occurred in 87 patients, 37 of whom also demonstrated persistent atrial tachyarrhythmias (ATAs). In 30 patients, first-degree AVB occurred 7 days to 120 months after heart transplantation. Among those, 88% demonstrated cellular rejection, and 20% developed transplant coronary artery disease (TCAD). Fifty patients demonstrated first-degree AVB without ATA, 32 of whom developed AVB from operative day 7 to 156 months. The incidence of cellular rejection was significantly lower (36%, P

Outcome of Multiple Caesarean Sections The reasons for increased incidence of caesarean section (CS) worldwide are a decline in trial of scar, increasing maternal age, reduction of operative vaginal delivery, medico-legal problems, caesarean section for breech presentation, patients demand for elective caesarean section and the relative safety of cesarean section in modern obstetrics. Even though the number of caesarean section a woman can undergo safely is still not established, in places where women procure more number of children due to socio religious reasons may have to undergo multiple repeat caesarean sections. This accounts for only a portion of caesarean section and are often overlooked when evaluating morbidity associated with abdominal delivery. The morbidities associated with multiple caesarean section are difficult to estimate and they are major placenta previa, placenta accrete, uterine ruptures, caesarean hysterectomy, severe adhesions, blood transfusions, surgical injury and wound complications. The data regarding maternal morbidity associated with multiple caesarean deliveries are important for counseling women with one cesarean delivery to undergo a trial of labor or a planned repeat caesarean section that will consequently lead to multiple caesarean deliveries. The objective of the study is to determine morbidity associated with multiple caesarean section compared to that associated with previous single caesarean section.

Degradable magnesium alloys are promising biomaterials for orthopedic applications. The aim of this study was to evaluate the potential effects on both the synovial membrane (synovialis) and the synovial fluid (synovia) of the degradation products of a MgYREZr-pin implanted in the intercondylar femoral notch in a rabbit model. Thirty-six animals were randomized into two groups (MgYREZr or Ti6Al4V alloy) of 18 animals each. Each group was then divided into three subgroups with implantation periods of 1, 4, and 12 weeks, with six animals in each subgroup. The initial inflammatory reaction caused by the surgical trauma declined after 12 weeks of implantation, and elucidated a progressive recovery of the synovial membrane. Compared with control Ti6Al4V pins, there were no significant differences between the groups. However, after 12 weeks, recovery of the synovial membrane was more advanced in the titanium group, in which 92% showed no signs of synovitis, than in the magnesium group. A cytotoxicity test with L929 cells and human osteoblasts (HOB) was also conducted, according to EN ISO 10993-5/12, and no toxic leachable products were observed after 24 h of incubation. In conclusion, the MgYREZr alloy seems to be a suitable material for intra-articular degradable implants. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Postpneumonectomy esophago-pleural fistula (EPF) is rare and potentially life-threatening. It is mainly caused by surgical injury, local cancer recurrence, and chronic inflammation or infection. Patients with postpneumonectomy EPF usually present with empyema. We report a case of a clinically asymptomatic esophago-pleural fistula, diagnosed accidentally in a 64-year-old woman more than 30 years after right lobe pneumonectomy due to tuberculosis. Contrast-enhanced CT, chest radiography, and esophagogramm were the imaging modalities used together with esophagoscopy in diagnosing the EPF; however, contrast-enhanced CT in combination with oral given contrast-media is the first imaging technique of choice to evaluate esophago-pleural fistula.

Surgical treatment of the Tetralogy of Fallot (ToF) is one of the great successes of medicine and also a topic of controversy. Different strategies have been proposed, including age-based (neonatal) management strategies as well as anatomic-based management strategies. Regardless of the management strategy entailed, the surgical management of ToF has considerably evolved over the years. As a result, patients can now expect excellent early results with survival approaching 100% for those without genetic syndromes. The goals of current surgical therapy should be to mitigate the late right ventricular (RV) dysfunction that may occur by minimizing the extent of surgical injury during the intial repair. As the surgical techniques continue to advance, the outcomes will continue to improve.

A case of medical negligence is presented involving both surgical injury and failure to diagnose the fault and provide appropriate corrective treatment.

Ulnar impaction syndrome generally occurs with positive ulnar variance. The solution to the problem is to unload the ulnocarpal joint. Effective surgical options include diaphyseal ulnar shortening osteotomy, open wafer osteotomy, and arthroscopic wafer osteotomy. Recently, Slade and Gillon described an open procedure of ulnar shortening in the osteochondral region of the ulnar head. The procedure minimizes the risk of hemarthrosis and does not require hardware removal, which are problems with other surgical options. This article introduces a new arthroscopic technique of distal metaphyseal ulnar shortening osteotomy for ulnar impaction syndrome. This technique offers the advantages of minimizing surgical injury to the dorsal capsule of the distal radoulnar joint and so protects its stability.

Benign biliary strictures (BBS) are most commonly caused by iatrogenic surgical injury, usually after cholecystectomy, or may occur at the site of biliary anastomosis after hepatic resection or liver transplantation. Other causes of BBS include primary sclerosing cholangitis, chronic pancreatitis, immunoglobulin G4–related cholangiopathy, and a variety of other causes. Endoscopic retrograde cholangiopancreatography has a pivotal role in the treatment of the vast majority of patients with BBS.

Igor Kissin, Simon GelmanDepartment of Anesthesiology, Perioperative and Pain Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USABackground: Surgical injury can frequently lead to chronic pain. Despite the obvious importance of this problem, the first publications on chronic pain after surgery as a general topic appeared only a decade ago. This study tests the hypothesis that chronic postsurgical pain was, and still is, represented insufficiently.Methods: We analyzed the presentation of this topic in journal articles covered by PubMed and in surgical textbooks. The following signs of insufficient representation in journal articles were used: (1) the lack of journal editorials on chronic pain after surgery, (2) the lack of journal articles with titles clearly indicating that they are devoted to chronic postsurgical pain, and (3) the insufficient representation of chronic postsurgical pain in the top surgical journals.Results: It was demonstrated that insufficient representation of this topic existed in 1981–2000, especially in surgical journals and textbooks. Interest in this topic began to increase, however, mostly regarding one specific surgery: herniorrhaphy. It is important that the change in the attitude toward chronic postsurgical pain spreads to other groups of surgeries.Conclusion: Chronic postsurgical pain is still a neglected topic, except for pain after herniorrhaphy. The change in the attitude toward chronic postsurgical pain is the important first step in the approach to this problem.Keywords: neuropathic pain, persistent pain, chronic pain, postoperative pain

Purpose To present a case report of a patient with atypical presentation of a conjunctival melanoma as an amelanotic tumor. Methods A 82-year-old female presenting a large amelanotic tumor in inferior tarsal conjunctiva of the right eye was referred to our hospital. Previous histological analysis diagnosed intraepithelial carcinoma. Imaging digital analysis techniques showed infiltration of the extrinsic ocular muscles but not the scleral tissue. Excisional biopsy was obtained by removing the tumor with free margins and preserving as many unaffected tissue as possible. Amniotic membrane graft was used to cover the surgical injury. Results Histopathological diagnosis confirmed amelanotic conjunctival melanoma. Systemic evaluation with imaging techniques (MRI, TC scan, Ecography…) revealed liver and kidney masses suggestive of metastasis and chemotherapy was prescribed to control the disease. Ophthalmological controls showed remission of tumor for 4 months, but new conjunctival masses appeared. At the present the patient is treated with palliative chemotherapy. Age and systemic status do not allow aggressive therapies in this patient. Conclusion Amelanotic melanoma is an atypical subtype of melanoma lacking of pigmentation. Its macroscopic aspect makes it almost impossible to clinically distinguish this tumor from less aggressive tumors, such as intraepithelial carcinomas. The diagnosis delay makes early treatment difficult in this malignant tumors.

The aim of this revue is to examine the current literature on the physio-pathological mechanism liable for the inflammatory reaction after major surgical injury and the nature and development of the related morbidity. We describe the endocrine and metabolic changes that occur as consequences of major thoracic surgery and the clinical implications of these reactions. The understanding of the stress response mechanism and the early detection of it’s clinical manifestations will aid in recognizing and probably help in correcting deviations from the norm.

Treatment of anterior cruciate ligament (ACL) tears in growing youths has evolved considerably over the past decade. There is a growing trend toward operative stabilization, because studies show the risks of not treating these injuries. We have gained experience on techniques that reduce the risk of surgical injury to the growing physis. Even for the complete tear of the ACL, controversies continue. Is there any role for nonoperative care? Is it safe to cross an open physis and before or after what age? How do we best determine skeletal maturity and remaining growth potential? Which “physeal-sparing” procedures best reproduce the native anatomy and therefore normal mechanics? Although the quantity and quality of scientifically sound information available to us limits our ability to be definitive, this article addresses the reliable scientific data that is available as well as expert experience and opinion. Published data regarding partial ACL injury, particularly in youths, are limited and opinions differ regarding diagnosis and treatment. The partial ACL injury debate starts with the fundamentals of definition and diagnosis, which makes the process of providing the patient with informed conclusions and treatment algorithms challenging. Nevertheless, partial injuries are a reality and clinical decisions must be made based on the sound principles and the best available data.

Adhesion of freely moving tissues and organs due to surgical injury and trauma can be a serious postoperative complication. High rates of incidence due to surgical intervention, especially associated with abdominal procedures, have been reported. This chapter gives an introduction to the formation of adhesions, with particular focus on peritoneum, urinary and reproductive (female) systems, tendon, ligament, joint, and pericardium.

Usually, stress is considered adverse: too much work load, or, conversely, ­unemployment; lack of success; unsolved family problems, etc. More scientifically, Selye (1936) discovered in his fundamental study by challenging rats that “if the organism is severely damaged by acute non-specific nocuous agents such as exposure to cold, surgical injury, production of spinal shock (transcision of the cord), excessive muscular exercise, or intoxications with sublethal doses of diverse drugs (adrenaline, atropine, morphine, formaldehyde, etc.), a typical syndrome appears, the symptoms of which are independent of the nature of the damaging agent or the pharmacological type of the drug employed, and represent rather a response to damage as such”.

Lower limb peripheral neuropathy may have a variety of causes. This article focuses on focal neural lesions because of neural entrapment associated with static mechanical compression or dynamic compression/stretching. Mechanical compression may relate to direct blunt trauma, surgical injury, mass effect associated with adjacent mass lesions, and frictional effects associated with fibrous bands. Stretching neural injury may be associated with abnormalities in alignment such as plano-valgus hindfoot and hindfoot pronation. Recurrent inversion ankle injuries may also cause neural injury. Neural injury may be associated with denervation of the muscles supplied by the nerve. Electromyography (EMG) remains the gold standard for diagnosis of denervation. Diagnostic imaging plays a complementary role to EMG in difficult cases, the anticoagulated patient, and in clarifying the etiology of an EMG-demonstrated neuropathy. Magnetic resonance imaging and ultrasound can be used in peripheral nerve imaging to demonstrate extrinsic compressive lesions, focal neural lesions such as neural edema and swelling, focal neural scarring (posttraumatic neuroma in continuity) and intraneural ganglia. Imaging can also demonstrate the effects of muscle denervation. Focal areas of tenderness can be highlighted using skin markers for magnetic resonance imaging and by transducer palpation on ultrasound. Ultrasound can be particularly useful in assessing for intrinsic lesions in small peripheral nerves because of the superior spatial resolution of ultrasound in assessing superficial structures. Plain x-rays (and sometimes computed tomography scanning) may show significant bone changes and should be the initial imaging modality.

A fistula is defined as an extra-anatomic communication between two or more epithelial or mesothelial lined body cavities or the skin surface. Fistula can occur as a result of congenital anomalies, malignancy, inflammation or infection, tissue trauma, or iatrogenic causes, such as surgical injury or radiation. There have been reports of fistula formation since ancient times, involving connections from the urinary tract to a myriad of bodily cavities and organs. Organ systems immediately adjacent to the urinary tract are the most commonly affected, specifically the reproductive, gastrointestinal, and vascular systems. Presenting signs and symptoms of urinary fistula are dependent on the termination point of the fistula, the fistula size, concomitant infection or inflammatory processes, and associated malignancy or other medical conditions.

Objective To evaluate the ability of the two currently available surgical barriers, oxidized regenerated cellulose and expanded-polytetrafluoroethylene (PTFE), to prevent postsurgical adhesions. Design Murine uterine horns were approximated in the midline and the contacting uterine surfaces injured by electrocautery, cutting, and scratching, with and without barriers interposed. Sham-operated and experimental animals had adhesions assessed visually and histologically 7days postoperatively. In another group, adhesions were created and then lysed 7days later with barriers interposed. Readhesion formation was assessed 14days after lysis with the PTFE being removed 7days after lysis. Setting Research laboratory Results Adhesions occurred at 58.5% of the electrocautery sites without barriers, 100% of the readhesion sites with recautery for hemostasis, and 92% of the recautery sites without hemostasis. None of the sham-operated sites developed adhesions. When oxidized regenerated cellulose was interposed, adhesions were observed at 36% of uninjured uterine horn sites, 62% with single and 92% with double electrocautery injuries and 90% of the reformation sites. The PTFE did not cause adhesions in uninjured controls and completely prevented adhesion formation and reformation, regardless of the type of injury or whether hemostasis was achieved. A thin cellular membrane, continuous with the uterine serosa, enveloped the PTFE. Conclusions Expanded-polytetrafluoroethylene, but not oxidized regenerated cellulose, prevents adhesion formation and reformation in this murine uterine horn model. Additionally, oxidized regenerated cellulose was adhesiogenic even without surgical injury.

Atrioventricular block may occasionally occur after surgical correction of truncus arteriosus. We therefore studied the conduction system by means of serial sections in five cases of truncus (one after surgical intervention) to delineate the course of the conduction system and its relationship to the ventricular septal defect and the membranous septum. In general, the ventricular septal defect is in the anterior septum, confluent with the truncus, and the atrioventricular bundle is posterior and unrelated to the rim of the ventricular septal defect. In cases in which the ventricular septal defect is anterior and separated from the membranous septum by distinct muscle, the ventricular septal defect can be surgically closed without injury to the atrioventricular bundle. If the ventricular septal defect is related to the membranous septum, the atrioventricular bundle may be close to the ventricular septal defect and susceptible to surgical injury. If muscle separates the ventricular septal defect from the membranous septum, the branching bundle is close to the ventricular septal defect and also is susceptible to surgical injury. In one operated case there was partial dissolution of the left bundle branch, and the right bundle branch was involved in surgical closure of the defect. In summary, in truncus the conduction system varies in its course and is related to the location of the ventricular septal defect and its relationship to the membranous septum. The ventricular septal defect may be close to or related to the membranous septum, and the atrioventricular bundle and the beginning of the bundle branches may be vulnerable to surgical injury.

Ten women had endometriosis and pelvic peritoneal defects of the posterior leaf of the broad ligament, with the consistent finding of medial displacement of the ureter toward the uterosacral ligament. Ureterolysis at the time of surgery revealed the underlying course of the ureter and its proximity to the uterosacral ligament, making it susceptible to surgical injury. It is important for surgeons to be aware of this anatomic alteration associated with these specific peritoneal defects.

Transient post-tonsillectomy taste dysgeusia (PTD) is a common complaint. Long-lasting PTD is less frequent but has significant consequences on patients' quality of life, with some cases leading to medicolegal issues. Treatment options and knowledge about mechanisms and factors favoring PTD are limited. PTD may result from direct surgical injury, tongue compression, inflammatory processes or side effects of local anesthetics. Some authors also claim that dietary zinc deficiency plays a role in the development of PTD. Although this latter cause had not yet received a lot of attention, we report a case of a female patient who reported a 4-year PTD and recovered within 2 months after oral intake of zinc sulfate. This clinical observation, together with recent findings on significant improvement of taste disorders after zinc treatments for other causes, opens again the question of what extent zinc deficiency plays a role in PTD.

Of 136 infants with repaired esophageal atresia, one presented an unilateral facial flushing and 2 presented a flushing and sweating of one half of the body. The topography of these disorders and/or the associated clinical manifestations suggest that the asymmetry may be related to an instability of unilateral autonomic centers more than to a surgical injury of upper thoracic sympathetic chain during esophageal repair.

There has traditionally been less concern regarding coronary anomalies with left-sided congenital heart lesions such as hypoplastic left heart syndrome (HLHS)or Shone complex than with other lesions. However, coronary anomalies in this setting can profoundly affect surgical intervention, particularly when surgical repair involves the ascending aorta. We describe four patients with congenital left-sided heart lesions in which left coronary artery (LCA) anomalies substantially affected intervention and outcome. In the first two cases, the coronary anomalies were not identified prospectively and resulted in surgical injury directly to the coronary or to its surrounding region. In the latter two cases, successful identification of the coronary anomaly preoperatively allowed for modification of surgical technique and/or intervention. We conclude that detailed coronary artery assessment should be part of the routine echocardiographic evaluation of congenital left-sided heart lesions that require surgery.

Background: A tense or competitive atmosphere in the operating room and unprofessional communication skills between members of the thorax and abdominal organ retrieval teams may lead to donor instability, inadequate organ preservation or surgical injury.
