Abstract Background Laparoscopy is common in abdominal surgery. Trocar site hernia (TSH) is a most likely underestimated complication. Among risk factors, obesity, the use of larger trocars and the umbilical trocar site has been described. In a previous study, CT scan in the prone position was found to be a reliable method for the detection of TSH following gastric bypass (LRYGB). In the present study, our aim was to examine the incidence of TSH after gastric sleeve, and further to investigate the proportion of symptomatic trocar site hernias. Methods Seventy-nine patients subjected to laparoscopic gastric sleeve in 2011–2016 were examined using CT in the prone position upon a ring. Symptoms of TSH were assessed using a digital survey. Results The incidence of trocar site hernia was 17 out of 79 (21.5%), all at the umbilical trocar site. The mean follow-up time was 37 months. There was no significant correlation between patient symptoms and a TSH. Conclusions The incidence of TSH is high after laparoscopic gastric sleeve, a finding in line with several recent studies as well as with our first trial on trocar site hernia after LRYGB. Up to follow-up, none of the patients had been subjected to hernia repair. Although the consequence of a trocar site hernia can be serious, the proportion of symptomatic TSH needs to be more clarified.

Abstract Aim Laparoscopy is common in abdominal surgery. Trocar site hernia (TSH) is a most likely underestimated complication. Among risk factors, obesity, the use of larger trocars and the umbilical trocar site has been described. In a previous study, CT scan in the prone position upon a ring was found to be a reliable method for the detection of TSH in obese. Our aim was to examine the incidence of TSH after gastric sleeve. Material and Methods 79 patients subjected to laparoscopic gastric sleeve in 2011-2016 were examined using CT in the prone position upon a ring. Symptoms of TSH were assessed using a digital survey. Results The incidence of trocar site hernia was 17 out of 79 (21,5 %), all at the umbilical trocar site. The mean follow-up time was 37 months. There was no clear correlation between symptomatic TSH and TSH on CT. Conclusions The incidence of TSH is high in this group of patients. Up to follow-up, none of the patients had been subjected to hernia repair. Although the consequence of trocar site hernia can be serious, the proportion of symptomatic TSH is unknown.

Introduction Investigations have demonstrated that trocar site hernia (TSH) is an under-appreciated complication of laparoscopic surgery, occurring in as many as 31%. We determined the incidence of fascial defects prior to laparoscopic appendectomy and its impact relative to other risk factors upon the development of TSH. Methods TSH was defined as a fascial separation of ≥ 1 cm in the abdominal wall umbilical region on abdominal computerized tomography scan (CT) following laparoscopic appendectomy. Patients admitted to our medical center who had both a preoperative CT and postoperative CT for any reason (greater than 30 days after surgery) were reviewed for the presence of TSH from May 2010 to December 2018. CT scans were measured for fascial defects, while investigators were blinded to film timing (preoperative or postoperative) and patient identity. Demographic information was collected. Results 241 patients undergoing laparoscopic appendectomy had both preoperative and late postoperative CT. TSH was identified in 49 (20.3%) patients. Mean preoperative fascial gap was 3.3 ± 4.3 mm in those not developing a postoperative hernia versus 14.8 ± 7.3 mm in those with a postoperative hernia ( P < .0001). Preoperative fascial defect on CT was predictive of TSH ( P < .001, OR = 1.44), with an Area Under the Curve (AUC) of .921 (95%CI: .88–.92). Other major risk factors for TSH were: age greater than 59 years ( P < .031, OR = 2.48); and obesity, BMI > 30 ( P < .012, OR = 2.14). Conclusions The incidence of trocar site hernia was one in five following laparoscopic appendectomy. The presence of a pre-existing fascial defect, advanced age, and obesity were strong predictors for the development of trocar site hernia.

Background:Currently it is hypothesized that many systemic autoimmune diseases occur due to environmental risk factors in addition to genetic risk factors. Anti-Neutrophil Cytoplasmic Antibody (ANCA) is mainly associated with three systemic autoimmune disease including granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), eosinophilic granulomatosis with polyangiitis (EGPA). It is known that ANCA can be positive before clinical symptoms in patients with known diagnosis of GPA and ANCA titers rise before clinical manifestations appear. However, prevalence of ANCA among general population is not well known. It has not been described as well how many of people with positive ANCA eventually develop clinical manifestations of ANCA associated Vasculitis.Objectives:This study aims to estimate prevalence of ANCA in general population without ANCA associated Vasculitis. It also describes natural disease course of people with positive ANCA without ANCA associated Vasculitis. Risk factors for positive ANCA are also analyzed.Methods:This is a single center retrospective study at Center for Preventive Medicine of St. Luke’s International Hospital in Tokyo. ANCA was checked among the patients who wished to between 2018 and 2019. St. Luke’s Health Check-up Database (SLHCD) was utilized to collect the data. The patients whose serum was measured for ANCA were identified. The data for basic demographics, social habits, dietary habits and laboratory data were extracted. The charts of the patients with positive ANCA were reviewed.Results:Sera of total 1204 people were checked for ANCA. Of these 1204 people, 587 (48.8%) are male and the mean age was 55.8 years (32.6 to 79). There were total 11 patients with positive ANCA. Myeloperoxidase ANCA (MPO-ANCA) was positive for 3 patients and proteinase 3 ANCA (PR3-ANCA) was positive for 8 patients. Of these 11 patients, 5 were male (45.5%) and the mean age was 54.6 years. Two patients had history of autoimmune disease (primary biliary cirrhosis and ulcerative colitis). Five patients were evaluated by rheumatologists with the median follow-up period of 274 days. None of them developed clinical signs and symptoms of ANCA associated Vasculitis. Four out of five patients had ANCA checked later, two of which turned negative. The prevalence of ANCA in this cohort was 0.9% (95% confidence interval [95% CI]: 0.5% to 1.6%). Univariate analysis was performed to identify risk factors of positive ANCA. The variables analyzed include age, gender, body mass index (BMI), smoking habits, alcohol intake, dietary habits (fruits, fish, red meat), hypertension, dyslipidemia, and laboratory data. None of these variables demonstrated statistically significant differences except for positive rheumatoid factor (ANCA positive group: 33 % vs ANCA negative group: 9.1%, p value = 0.044).Conclusion:The prevalence of ANCA in this cohort was 0.9% (95% CI: 0.5% to 1.6%). None of them who had a follow-up developed ANCA associated Vasculitis during the follow-up period. Longer follow-up and more patients are necessary to determine natural course of people with positive ANCA.Disclosure of Interests:None declared

The Mean

Vertical midline mandibulotomy has provided a relatively simple and efficient means of obtaining access to intraoral tumors that are too large or too posterior to be removed transorally. Midline mandibulotomy has had the advantage of nerve and muscle preservation and places the osteotomy outside the typical field of radiotherapy, in contrast to lateral and paramedian osteotomies. Plate and screw fixation has been the usual means of osteosynthesis for these mandibulotomies; however, plate contouring over the symphyseal surface has been a time-consuming process. Unless the plate was contoured exactly, mandibular malalignment and malocclusion in dentulous patients has occurred. Use of parallel transverse lag screws has become a popular method of osteosynthesis for parasymphyseal fractures, and we have extended their use for mandibulotomy fixation. This paper reports our clinical experience with transverse lag screw fixation of midline mandibulotomies in 9 patients from 1994 to 1997. There were 7 men and 2 women with a mean age of 56 (range 35 to 71 years). The pathological diagnosis in all patients was squamous cell carcinoma; 8 cases were primary, and 1 patient presented with recurrent tumor. No tumors involved the mandibular periosteum. One patient had had previous radiotherapy, and 3 patients underwent postoperative radiotherapy. The mean follow-up has been 17 months (range 9 to 27). There was 1 minor complication and 1 major complication related to our technique. The major complication was a delayed nonunion of the mandibulotomy. This occurred because the 2 parallel screws were placed too close to one another, and this placement resulted in a delayed sagittal fracture of the anterior cortex and subsequent nonunion. Transverse lag screw fixation has not affected occlusion in our dentulous patients. Speech and diet were normal in the majority of our patients. Transverse lag screw fixation of the midline mandibulotomy has been a relatively safe, rapid, and reliable method for tumor access and postextirpation mandibular stabilization and has significant advantages over other current methods of mandibulotomy and fixation.

Risk Of Hemorrhage

Object A small percentage of patients will develop a completely new or de novo aneurysm after discovery of an initial aneurysm. The natural history of these lesions is unknown. The authors undertook this statistical evaluation a large cohort of patients with both ruptured and unruptured de novo aneurysms with the aim of analyzing risk factors for rupture and estimating a risk of subarachnoid hemorrhage (SAH). Methods A review of a prospectively maintained database of all aneurysm patients treated by the vascular neurosurgery service of Goodman Campbell Brain and Spine from 1976–2010 was performed. Of the 4718 patients, 611 (13%) had long-term follow-up imaging. The authors identified 27 patients (4.4%) with a total of 32 unruptured de novo aneurysms from routine surveillance imaging. They identified another 10 patients who presented with a new SAH from a de novo aneurysm after treatment of their original aneurysm. The total study group was thus 37 patients with a total of 42 de novo aneurysms. The authors then compared the 27 patients with incidentally discovered aneurysms with the 10 patients with SAH. A statistical analysis was performed, comparing the 2 groups with respect to patient and aneurysm characteristics and risk factors. Results Thirty-seven patients were identified as having true de novo aneurysms. This group had a female predominance and a high percentage of smokers. These 37 patients had a total of 42 de novo aneurysms. Ten of these 42 aneurysms hemorrhaged. De novo aneurysms in both the SAH and non-SAH group were anatomically small (< 10 mm). The estimated risk of hemorrhage over 5 years was 14.5%, higher than the expected SAH risk of small, unruptured aneurysms reported in the ISUIA (International Study of Unruptured Intracranial Aneurysms) trial. There was no statistically significant correlation between hemorrhage and any of the following risk factors: hypertension, diabetes, tobacco and alcohol use, polycystic kidney disease, or previous SAH. There was a statistically significant between-groups difference with respect to patient age, with the mean patient age being significantly older in the SAH aneurysm group than in the non-SAH group (p = 0.047). This is likely reflective of longer follow-up and discovery time, as the mean length of time between initial treatment and discovery of the de novo aneurysm was longer in the SAH group (p = 0.011). Conclusions While rare, de novo aneurysms may have a risk for SAH that is comparatively higher than the risk associated with similarly sized, small, initially discovered unruptured saccular aneurysms. The authors therefore recommend long-term follow-up for all patients with aneurysms, and they consider a more aggressive treatment strategy for de novo aneurysms than for incidentally discovered initial aneurysms.

The Mean

This study evaluates the outcome of axillary nerve injuries treated with nerve grafting. Thirty-six patients were retrospectively reviewed after a mean of 53 months (minimum 12 months). The mean interval from injury to surgery was 6.5 months. Recovery of deltoid function was assessed by the power of both abduction and retropulsion, the deltoid bulk and extension lag. The deltoid bulk was almost symmetrical in nine of 34 cases, good in 22 and wasted in three. Grade M4 or M5* was achieved in 30 of 35 for abduction and in 32 of 35 for retropulsion. There was an extension lag in four patients. Deltoid bulk continued to improve with a longer follow-up following surgery. Nerve grafting to the axillary nerve is a reliable method of regaining deltoid function when the lesion is distal to its origin from the posterior cord.

Abstract Background The medial patellofemoral ligament (MPFL) is always damaged after patellar dislocation. In selected patients, MPFL reconstruction is necessary to restore a correct patellar tracking. Despite the large number of different techniques reported to reconstruct the MPFL, there is no consensus concerning the optimal procedure, and debates is still ongoing. The present study analysed the results after isolated MPFL reconstruction in patients with patellofemoral instability. Furthermore, a subgroup analysis of patients presenting pathoanatomical risk factors was made. Methods In November 2020, the main electronic databases were accessed. All articles reporting the results of primary isolated MPFL reconstruction for recurrent patellofemoral instability were considered for inclusion. Only articles reporting a minimum 12-month follow-up were eligible. Results Data from a total of 1777 knees were collected. The mean age of the patients involved was 22.8 ± 3.4 years. The mean follow-up was 40.7 ± 25.8 months. Overall, the range of motion (+ 27.74; P < 0.0001) and all the other scores of interests improved at last follow-up: Kujala (+ 12.76; P = 0.0003), Lysholm (+ 15.69; P < 0.0001), Tegner score (+ 2.86; P = 0.006). Seventy-three of 1780 patients (4.1%) showed a positive apprehension test. Thirty of 1765 patients (1.7%) experienced re-dislocations, while 56 of 1778 patients (3.2%) showed persisting joint instability. Twenty-five of 1786 patients (1.4%) underwent revision surgeries. Conclusion Isolated MPFL reconstruction for recurrent patellofemoral instability provides reliable surgical outcomes. Patients with pathoanatomical predisposing factors reported worse surgical outcomes.

Purpose: To analyze the risk factors associated with early and late failure after goniotomy for primary pediatric glaucoma. Methods: A retrospective study was done on infants who underwent goniotomy as the initial surgical procedure for primary pediatric glaucoma, and had a follow-up period ⩾48 months after surgery. Early and late failures were defined as intraocular pressure ⩾18 mmHg or signs of glaucoma progression before and after the end of first year, respectively. Results: A total of 81 eyes of 47 children were included. The mean age at the time of surgery was 6.1 ± 6.7 months, 34 children (72.3%) were bilateral. The mean follow-up was 5.9 ± 2.8 years. Of the included eyes, 41 eyes (50.6%) showed success, 25 eyes (30.9%) showed an early failure, and 15 eyes (18.5%) showed a late failure. The mean survival time was 43 months. However, only surgery before the end of the first month and positive consanguinity of the parents (P < 0.01 for both) were independent risk factors for early and late failure of goniotomy for primary pediatric glaucoma. Patients with late failure showed a statistically significant lower preoperative intraocular pressure (P = 0.02). A larger preoperative corneal diameter and a male gender were associated with higher but statistically insignificant failure rates. There were no differences in the early or late failure rates between unilateral and bilateral cases. Conclusion: A positive consanguinity of the parents and surgery before the end of the first month are the major predictors of failure of goniotomy.
