Treatment of Major Laparoscopic Bile Duct Injury: A Long-Term Follow-up Result

The goal of this study is to present the multiple institutions experience comparing the outcome of management between initial laparoscopic cholecystectomy (LC) surgeon and specialist as well as the outcome of different operative procedures to major bile duct injury (BDI) after LC. We have retrospectively collected data of 77 cases of perioperatively detected major BDI in LC at 15 general surgical institutions from 1997 to 2007. We classified 42 cases treated by an experienced biliary surgeon as Group A and 35 cases treated by the initial LC surgeon as Group B. Forty-eight cases were treated with duct-to-duct anastomosis as Group C and 29 cases were treated with Roux-en-Y choledochojejunostomy as Group D. The median duration of follow-up was 62 months. The outcome of groups was compared. In Group A, 7 of 42 (16.7%) patients developed a failure. Two of seven (28.6%) patients were treated by a secondary operation. In Group B, 24 of 35 (68.6%) patients developed a failure. Seventeen of 24 (70.8%) patients were treated by a secondary operation. One of 35 (2.85%) patients died. The significant differences were observed in failure and secondary operations (16.7 vs 68.6%, P < 0.01 and 28.6 vs 70.8%, P < 0.01). There is no significant difference Group C and Group D in failure rate (28.5 vs 11.7%, P > 0.05). A multiple institutional cooperative methodology between the local surgical institution and tertiary care centers provided a good way to limit further operations, failure. The reconstructive strategy is important and should be selected according to the type of injury and the diagnosed status of major BDI.

Background: Plantar fasciitis is a common cause of heel pain in adults. Although it is usually a self-limiting condition, the pain may become prolonged and severe enough to cause significant distress and disruption to the patient’s daily activities and work. The primary objective of the study was to evaluate and compare the effectiveness of autologous platelet rich plasma (PRP) and steroid injections in chronic cases of plantar fasciitis (PF).Methods: A prospective, randomized study was conducted from December 2013 to December 2015 amongst 60 patients with chronic PF were randomized prospectively in single tertiary care center in India. All the patients were enrolled according to inclusion criteria and divided into 2 groups i.e. group A (n=30) received PRP and group B (n=30) received corticosteroids injections. Roles and Maudsley score (RM Score) and Foot Function Index (FFI) was evaluated for all the included patients. The follow-up scheduled at 1 and 6 months after complete enrolment of patients.Results: Between both the groups, the significant difference was observed at 1 and 6 months follow-up from the baseline. At 1-month follow-up, statistically significant improvement in mean RM scores were seen in both the groups from baseline and when RM scores were compared between two groups, group B had statistically better mean scores. At 1-month follow-up there was no statistically significant difference between the mean FFI score values between two groups. At 6-month follow-up, statistically significant improvement in mean FFI scores were seen in both the groups, however when both groups were compared to each other, improvement in mean FFI scores was statistically better in group A as compared to group B.Conclusions: The present study concluded the use of PRP in chronic cases of plantar fasciitis seems more safe and effective in long term than the traditional treatment of steroid injection at different time period.

Abstract This study compared the effects of different dosages of intravenous immunoglobulin (IVIg) against immune thrombocytopenia. A total of 167 patients, 91 adults and 76 children, with ITP, followed-up for 3 years in the case-control study, were each divided into three subgroups according to the dosages of IVIg administered: group A (0.2g/kg/day), group B (0.3g/kg/day), group C (0.4g/kg/day). The therapeutic response in 91 adult patients did not differ significantly among the three groups of IVIg dosages (P=0.459). The response rate of IVIg treatment in the three adult groups was 97.1% for group A, and 97.2% for group B, 100% for group C. The mean time for raising platelets to 30 ×109/L in group A was 2.5 days, group B 3.2 days, group C 2.9 days (P=0.324). The median IVIg consumption in group A was 0.83 g/kg, group B 1.22 g/kg, and group C 1.64 g/kg (P<0.01). Similar results were shown in the children groups. The follow-up results showed no significant difference of clinical outcome between groups A, B and C. In conclusion, low-dose IVIg treatment is shown to be as effective as high-dose regimen without increasing the risk of developing the patients into chronic ITP conditions, suggesting that ITP patients could be treated more cost-effectively by lower than conventional dosage of IVIg regimen. Disclosures No relevant conflicts of interest to declare.

Object Suprasellar arachnoid cysts (SACs) are rare, comprising approximately 10% of all intracranial arachnoid cysts. Although neuroendoscopic management is emerging as a safe effective alternative to microsurgery, the type of endoscopic surgery whether ventriculocystostomy (VC) or ventriculocystocisternostomy (VCC) is still controversial. This study evaluates the role of endoscopy in the treatment of SACs in children. It compares VC and VCC to determine which procedure is superior in the long term. Methods Twenty-five children (14 boys and 11 girls; mean age 26 months) with symptomatic SACs associated with hydrocephalus are the subject of this study. According to the surgical procedure adopted, patients were divided into 2 groups. Patients in Group A (11 patients) underwent VC with a mean follow-up of 55 months, and those in Group B (14 patients) underwent VCC with a mean follow-up of 64.7 months. Results Both procedures proved to be effective clinically and radiologically. The incidence of improvement of hydrocephalus-related symptoms was 63.6% in Group A compared with 85.7% in Group B. Improvement in cyst size and hydrocephalus after VC was 81.8% and 63.6%, respectively, compared with 100% and 85.7%, respectively, after VCC. There were no deaths or permanent morbidity, and no patient was left with a permanent shunt. Recurrence occurred in 3 cases after VC (27.3%), whereas no recurrence (0%) was encountered after VCC. At a second endoscopic procedure, the fenestration was found to be closed in all 3 recurrent cases. Conclusions An endoscopic procedure is recommended in the treatment of SACs in children because it is simple, effective, minimally invasive, and associated with low morbidity and mortality rates. Both procedures, VC and VCC, proved to be almost equally effective clinically and radiologically. Nevertheless, because of the statistically significant difference between the incidence of recurrence after VC and VCC during long-term follow-up, the author concludes that VCC should be considered as the procedure of choice in the treatment of these cases. The important finding of reclosure of the VC fenestration in the recurrent cases underscores the significance of performing cystocisternostomy at initial surgery to guard against cyst recurrence.

Background: A large proportion of blast victims suffers ear injuries; however, these injuries are often overlooked.Methods: We assessed 411 blast victims to detect ear injury employing detailed history, otological examination, pure tone audiometry, auditory steady state response and distortion product otoacoustic emissions. TM perforations were managed by thorough cleaning of ear by suctioning, edges approximation and gelfoam splinting in group A and only suctioning in group B. Prednisolone in tapering doses was prescribed for managing hearing loss in all except those in whom it was contraindicated. Results: Out of 411 blast victims, 228 (55.47%) had aural trauma. All cases were males (being serving soldiers) between ages of 21 and 57 years. (Mean 37.77 years, SD 10.38). 285 ears had a perforated TM. Of these, 145 were assigned to group A while 140 were in group B. There was no significant difference in spontaneous healing of perforation between the two groups but at 5 years’ follow up group A had significantly higher number of unscarred, healthy TMs than group B (Z score=2.2111, p=0.0271). Mean pure tone average was 51.16 dB (SD 8.79 dB) at presentation and 38.91 dB (SD 7.86 dB) at 5 years. Recovery of SNHL component was significantly better in steroid treated patients.Conclusions: Edges approximation and gelfoam splinting helped in reducing scarring of TM on healing, on long follow up. Steroid treated group showed better recovery of hearing loss.

Background: Laparoscopic Incisional and Ventral Hernia Repair (LIVHR) is a safe and worldwide accepted procedure performed using absorbable tacks. The aim of the study was to evaluate recurrence rate in a long term follow-up and whether the results of laparoscopic IVH repair in the elderly (≥65 years old) are different with respect to results obtained in younger patients. Methods: One hundred and twenty-nine consecutive patients (74 women and 55 men, median age 67 years, range = 30-87 years) with ventral (N = 42, 32.5%) or post incisional (N = 87, 67.5%) hernia were enrolled in the study. Patients were divided into two groups according to their age: group A (N = 55, 42.6%) aged <65 years and group B (N = 74, 57.4%) aged ≥65 years. Results: The mean operative time was not significantly different between groups (66.7 ± 37 vs. 74 ± 48.4 min, p = 0.4). To the end of 2016, seven recurrences had occurred (group A = 3, group B = 4, p = 1). Complications occurred in 8 (16%) patients in group A and 21 (28.3%) patients in group B. Conclusion: In conclusion, our results confirm that the use of absorbable tacks does not increase recurrence frequency and laparoscopic incisional and ventral repair is a safety procedure also in elderly patients.

Introduction: The aim of this was to describe the predictors of mortality related to COVID-19 infection and to evaluate the association between overweight, obesity, and clinical outcomes of COVID-19. Methods: We included the patients >18 years of age, with at least one positive SARS-CoV-2 reverse transcriptase-polymerase chain reaction. Patients were grouped according to body mass index values as normal weight <25 kg/m2 (Group A), overweight from 25 to <30 kg/m2 (Group B), Class I obesity 30 to <35 kg/m2 (Group C), and ≥35 kg/m2 (Group D). Mortality, clinical outcomes, laboratory parameters, and comorbidities were compared among 4 groups. Results: There was no significant difference among study groups in terms of mortality. Noninvasive mechanical ventilation requirement was higher in group B and D than group A, while it was higher in Group D than Group C (Group B vs. Group A [p = 0.017], Group D vs. Group A [p = 0.001], and Group D vs. Group C [p = 0.016]). Lung involvement was less common in Group A, and presence of hypoxia was more common in Group D (Group B vs. Group A [p = 0.025], Group D vs. Group A [p < 0.001], Group D vs. Group B [p = 0.006], and Group D vs. Group C [p = 0.014]). The hospitalization rate was lower in Group A than in the other groups; in addition, patients in Group D have the highest rate of hospitalization (Group B vs. Group A [p < 0.001], Group C vs. Group A [p < 0.001], Group D vs. Group A [p < 0.001], Group D vs. Group B [p < 0.001], and Group D vs. Group C [p = 0.010]). Conclusion: COVID-19 patients with overweight and obesity presented with more severe clinical findings. Health-care providers should take into account that people living with overweight and obesity are at higher risk for COVID-19 and its complications.

Background:Cardiovascular disease (CVD) is detected in up to 50% of systemic lupus erythematosus (SLE) patients1and major cause of death2. Even clinically silent SLE patients can develop left ventricular (LV) diastolic dysfunction3. Proper echocardiographic follow up of SLE patients is required.Objectives:To clarify how the prevalence of LV abnormalities changes over follow-up period and identify the associated clinical factors, useful in suspecting LV abnormalities.Methods:29 SLE patients (24 females and 5 men, mean age 52.8±16.3 years, mean disease duration 17.6±14.5 years) were enrolled. All of them underwent echocardiography as the baseline examination and reexamined over more than a year of follow-up period(mean 1075±480 days) from Jan 2014 to Sep 2019. Patients complicated with pulmonary artery hypertension, deep venous thrombosis or pulmonary embolism and underwent cardiac surgery during the follow-up period were excluded. Left ventricular(LV) systolic dysfunction was defined as ejection fraction (EF) < 50%. LV diastolic dysfunction was defined according to ASE/EACVI guideline4. LV dysfunction (LVD) includes one or both of LV systolic dysfunction and LV diastolic function. Monocyte to HDL ratio (MHR) was calculated by dividing monocyte count with HDL-C level.Prevalence of left ventricular abnormalities was analysed at baseline and follow-up examination. Clinical characteristics and laboratory data were compared among patient groups as follows; patients with LV dysfunction (Group A) and without LV dysfunction (Group B) at the follow-up echocardiography, patients with LV asynergy at any point of examination (Group C) and patients free of LV abnormalities during the follow-up period (Group D).Results:At the baseline examination, LV dysfunction (5/29 cases, 13.8%), LV asynergy (6/29 cases, 21.7%) were detected. Pericarditis was detected in 7 patients (24.1%, LVD in 3 patients, LV asynergy in 2 patients) and 2 of them with subacute onset had progressive LV dysfunction, while 5 patients were normal in echocardiography after remission induction therapy for SLE. At the follow-up examination, LV dysfunction (9/29 cases, 31.0%, 5 new-onset and 1 improved case), LV asynergy (6/29 cases, 21.7%, 2 new-onset and 2 improved cases) were detected. Though any significant differences were observed between Group A and Group B at the baseline, platelet count (156.0 vs 207.0, p=0.049) were significantly lower in LV dysfunction group (Group A) at the follow-up examination. Group C patients had significantly higher uric acid (p=0.004), monocyte count (p=0.009), and MHR (p=0.003) than Group D(results in table).Conclusion:LV dysfunction is progressive in most of patients and requires regular follow-up once they developed. Uric acid, monocyte count and MHR are elevated in SLE patients with LV asynergy. Since MHR elevation was reported as useful marker of endothelial dysfunction5, our future goal is to analyse involvement of monocyte activation and endothelial dysfunction in LV asynergy of SLE patients.References:[1]Doria A et al.

Abstract Background Pernicious placenta previa (PPP) can increase the risk of perioperative complications. During caesarean section in patients with adherent placenta, intraoperative blood loss, hysterectomy rate and transfusion could be reduced by interventional methods. Our study aimed to investigate the influence of maternal hemodynamics control and neonatal outcomes of prophylactic temporary abdominal aortic balloon (PTAAB) occlusion for patients with pernicious placenta previa. Methods This was a retrospective study using data from the Peking University People’s Hospital from January 2014 through January 2020. Clinical records of pregnant women undergoing cesarean section were collected. Patients were divided into two groups: treatment with PTAAB placement (group A) and no balloon placement (group B). Group A was further broken down into two groups: prophylactic placement (Group C) and balloon occlusion (group D). Results Clinical records of 33 cases from 5205 pregnant women underwent cesarean section were collected. The number of groups A, B, C, and D were 17, 16, 5 and 12.We found that a significant difference in the post-operative uterine artery embolism rates between group A and group B (0% vs.31.3%, p = 0.018). There was a significant difference in the Apgar scores at first minute between group A and group B (8.94 ± 1.43 vs 9.81 ± 0.75,p = 0.037),and the same significant difference between two groups in the pre-operative central placenta previa (29.4% vs. 0%,p = 0.044), complete placenta previa (58.8% vs 18.8%, p = 0.032),placenta implantation (76.5% vs 31.3%, p = 0.015). We could also observe the significant difference in the amount of blood cell (2.80 ± 2.68vs.10.66 ± 11.97, p = 0.038) and blood plasma transfusion (280.00 ± 268.32 vs. 1033.33 ± 1098.20, p = 0.044) between group C and group D. The significant differences in the preoperative vaginal bleeding conditions (0% vs 75%, p = 0.009), the intraoperative application rates of vasopressors (0% vs. 58.3%, p = 0.044) and the postoperative ICU (intensive care unit) admission rates (0% vs. 58.3%, p = 0.044) were also kept. Conclusions PTAAB occlusion could be useful in reducing the rate of post-operative uterine artery embolism and the amount of transfusion, and be useful in coping with patients with preoperative vaginal bleeding conditions, so as to reduce the rate of intraoperative applications of vasopressors and the postoperative ICU (intensive care unit) admission. In PPP patients with placenta implantation, central placenta previa and complete placenta previa, we advocate the utilization of prophylactic temporary abdominal aortic balloon placement.

OBJECTIVE Posterior C1–2 fixation without fusion makes it possible to restore atlantoaxial motion after removing the implant, and it has been used as an alternative technique for odontoid fractures; however, the long-term efficacy of this technique remains uncertain. The purpose of the present study was to explore the long-term follow-up outcomes of patients with odontoid fractures who underwent posterior C1–2 fixation without fusion. METHODS A retrospective study was performed on 62 patients with type II/III fresh odontoid fractures who underwent posterior C1–2 fixation without fusion and were followed up for more than 5 years. The patients were divided into group A (23 patients with implant removal) and group B (39 patients without implant removal) based on whether they underwent a second surgery to remove the implant. The clinical outcomes were recorded and compared between the two groups. In group A, the range of motion (ROM) of C1–2 was calculated, and correlation analysis was performed to explore the factors that influence the ROM of C1–2. RESULTS A solid fracture fusion was found in all patients. At the final follow-up, no significant difference was found in visual analog scale score or American Spinal Injury Association Impairment Scale score between the two groups (p > 0.05), but patients in group A had a lower Neck Disability Index score and milder neck stiffness than did patients in group B (p < 0.05). In group A, 87.0% (20/23) of the patients had atlantoodontoid joint osteoarthritis at the final follow-up. In group A, the C1–2 ROM in rotation was 6.1° ± 4.5° at the final follow-up, whereas the C1–2 ROM in flexion-extension was 1.8° ± 1.2°. A negative correlation was found between the C1–2 ROM in rotation and the severity of tissue injury in the atlantoaxial region (r = –0.403, p = 0.024) and the degeneration of the atlantoodontoid joint (r = –0.586, p = 0.001). CONCLUSIONS Posterior C1–2 fixation without fusion can be used effectively for the management of fresh odontoid fractures. The removal of the implant can further improve the clinical efficacy, but satisfactory atlantoaxial motion cannot be maintained for a long time after implant removal. A surgeon should reconsider the contribution of posterior C1–2 fixation without fusion and secondary implant removal in preserving atlantoaxial mobility for patients with fresh odontoid fractures.
