An Abdominal Textiloma Simulating an Intestinal Tumour: A Case Report

The textiloma, being an inflammatory granuloma that is secondary to a foreign body left involuntarily at the level of the operative site with an unpredictable evolution, constitutes a relatively rare postoperative complication, with a misleading clinical-radiological presentation, as well as potentially serious complications and forensic proceedings involving the responsibility of the surgeon. Although surgery is the means of choice to confirm the diagnosis and to treat the disease, taking serious preventive measures remains the only solution to avoid this type of incident. We report the case of an intestinal tumor syndrome revealing an abdominal textiloma.

Aesthetic Improvement of Body Proportion Through Trunk Liposculpture: A Waistline-based Strategy.

Abdominal contouring through liposuction has been practiced for decades. However, few studies have focused on describing the definition and enhancement of the waistline in torso contouring procedures. In the present study, the authors proposed a waistline-based strategy for abdominal liposculpture to achieve a better aesthetic outcome and emphasize high overall patient satisfaction. The data of patients who underwent the waistline-based liposculpture procedure from 2020 to 2023 were retrospectively reviewed. Aesthetic improvement of the central trunk contour was evaluated and analyzed by comparing preoperative and postoperative photogrammetric measurements. Satisfaction with the outcome was assessed with a patient satisfaction questionnaire. A total of 70 patients were enrolled in this study. During 6 months of postoperative evaluation, the shape of the central trunk contour improved significantly (both waist concavity and hip convexity increased quantitatively, P < .05), while the position of the waist did not differ significantly postoperatively (P > .05). All patients were satisfied with their postoperative outcomes, including their overall aesthetic appearance, waistline position, and waist-to-hip ratio. There were no intraoperative complications or rare postoperative complications. Waistline-based liposculpture is a simple and effective procedure to improve the aesthetic outcomes of trunk contouring and has highly satisfactory results after long-term follow-up.

Recipient site scalp necrosis: A rare postoperative complication of hair transplantation.

Recipient area scalp necrosis is considered a potential complication of hair transplantation, but has rarely been reported. A small number of patients have developed scalp necrosis after hair transplantation with the widely used Follicular unit excision (FUE) technique. There are no guidelines to prevent and manage this complication. The aim of this study was to provide an insight into the pathogenesis, prevention, and management of scalp necrosis following hair transplantation. From 2012 to 2021, among more than 10 000 patients who underwent hair transplantation, only three developed scalp necrosis in our clinical experience, besides, one patient transferred to our hospital because of scalp necrosis after undergoing hair transplantation. According to the disease etiology and patients' symptom, a combination of wound management and antimicrobial therapy was employed. This study was approved by the institutional ethics committee of Nanfang Hospital. Of the four patients, three received timely treatment and had a good prognosis. Necrosis became confined and healed within 2-3 weeks. Grafts in the lesion area partially survived. In case 4, due to improper treatment at the early stage, the lesion developed extensively and deeply, which not only delayed wound healing, but also resulted in complete loss of grafts. Preoperative prophylaxis, timely diagnosis, and immediate treatment of scalp necrosis can prevent serious complications and reduce morbidity after hair transplantation.

Novel indications for autologous fat grafting in reconstruction: scleroderma

Scleroderma is a chronic connective tissue disease characterized by inflammation, vascular injury, and progressive skin fibrosis, resulting in significant aesthetic and functional impairments for patients. Current therapies are limited and insufficiently treat the cutaneous manifestations of scleroderma. Autologous fat transfer (AFT) is a surgical technique that has been utilized for many decades for facial rejuvenation. The adipose stem cells (ASCs) present in fat grafts have also shown significant promise for their anti-inflammatory and regenerative properties. Recently, AFT has been repurposed to treat the skin manifestations of systemic sclerosis and localized scleroderma. Studies suggest that AFT in scleroderma patients improves mouth and hand functions, Raynaud’s symptoms, and digital ulcerations. AFT is a safe procedure with rare postoperative complications, making it a promising intervention for the treatment of scleroderma. Further studies are required to better characterize the influence of fat grafts on the recipient site and to establish standards for fat transfer in fibrotic skin diseases.

Concurrent paraesophageal hernia repair in revisional/conversional laparoscopic Roux-en-Y gastric bypass: propensity score-matched analysis of the MBSAQIP database.

Patients requiring concurrent paraesophageal hernia repair (CPHR) have been shown to have favorable outcomes in primary bariatric surgery. However, patients requiring revisional or conversional surgery represent a group of patients with higher perioperative risk. Currently, few reports on concurrent paraesophageal hernia repair utilizing the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database are available. The primary aim of this study was to determine perioperative complications associated with CPHR and the Roux-en-Y gastric bypass (RYGB) as a revisional/conversional operation. In this study, patients undergoing revisional/conversional RYGB between 2015 and 2020 were accessed via the MBSAQIP database. Patients were categorized based on the presence of a paraesophageal hernia as a concurrent procedure. Patients who underwent revisional/conversional surgery without additional procedures were utilized for controls. A propensity score-matched cohort was generated and E-analysis utilized to assess unmeasured confounding. After exclusions, 35,698 patients were available. Patients receiving CPHR were more likely to be female (90.79% vs 87.37%; p < 0.001) and have increased frequency of gastroesophageal reflux disease (69.20% vs 51.69%; p < 0.001). However, these patients had lower frequencies of sleep apnea (24.12% vs 30.13%; p < 0.001), hypertension requiring medication (38.51% vs 42.59%; p < 0.001), and decreased frequency of hyperlipidemia (19.44% vs 21.60%;p < 0.001). After matching, 6,231 patient pairs were developed and showed that patients undergoing CPHR were at increased risk of readmission (9.44% vs 7.58%; p < 0.001), intervention (3.56% vs 2.79%; p = 0.018), increased requirement for outpatient dehydration treatment (5.87% vs 4.67%;p = 0.004), and overall increased operation time (169.3min ± 76.0 vs 153.5 ± 73.3; p < 0.001). However, there were no significant increases in the rates of reoperation, death, postoperative leak complications, or bleeding complications after CPHR. Patients undergoing revisional/conversional RYGB with CPHR may be at higher risk for a small number of rare postoperative complications. CPHR is a safe procedure in patients undergoing revisional/conversional RYGB in the short-term postoperative period.

Spontaneous distal migration of Kuntscher intramedullary nail into leg from malunited distal femur fracture: A rare case report

Kuntscher cloverleaf nail, also called as K-nail, is an intramedullary nail (IMN), made from stainless steel with a slot along the longitudinal axis. It is used in fixation of short oblique, simple transverse, Winquist- I and II comminuted fractures of femur. This was a case in which the Kuntscher nail spontaneously migrated distally, and was extruded completely from the femur into the leg along the posterior aspect till the ankle with the most probable cause being malunion of an oblique distal femur fracture. There were no recent reports on this type of distal migration till date. A 72-year-old male, who is working as farmer in a rural area, came to our institution with pain and swelling on &amp; off around the left ankle for last two months during May 2022. Local examination of left lower limb revealed that there was swelling around the left ankle. There was a palpable hard metallic object posterior to the left medial malleolus. There is a single well healed surgical scar of length 10 cms on the lateral aspect of left distal thigh. Radiological workup was done accordingly. Final diagnosis was – Postoperative spontaneous migration of Kuntscher nail into the leg from a malunited fracture of lower 1/3 of left femur. Treatment plan was implant removal. After implant removal, the patient was discharged in a stable condition and follow-up till 6 months revealed no complaints around the ankle or knee joints. Distal migration of K-nail across the knee joint after femur diaphyseal fracture fixation is a rare and preventable complication. It is recommended that K-nails should be routinely removed as soon as radiological union and consolidation of the fracture is confirmed, to avoid rare postoperative complication of distal migration of the K-nail.

A case report of interstitial keratitis and secondary glaucoma after cataract surgery that may be related to late congenital syphilis

BackgroundThe destruction of blood eye barrier and the administration of corticosteroid eyedrops after phacoemulsification surgery can lead to the replication of the local potential pathogens. With the rapid increase and popularization of cataract surgery, all kinds of rare postoperative complications have appeared. Here, we report a case of interstitial keratitis and secondary glaucoma after cataract surgery, which may be related to late congenital syphilis, which eventually led to blindness in the right eye. We hope that the timely report of this case will enable doctors to pay more attention to the possibility of potential pathogen replication after cataract surgery, and enable more patients to receive reasonable and effective treatment.Case presentationA 63-year-old female was referred to our clinic for investigation with a 1-week history of moderate pain in the right eye and ipsilateral headache in January 2020. She had cataract surgery on her right eye two years ago and on her left eye one year ago. The intraocular pressure (IOP) in the right eye was 43.2 mmHg and that in the left eye was 28.5 mmHg. Her right eye underwent medication, trabeculectomy and finally was subjected to ciliary body photocoagulation to control the IOP. The IOP of the left eye was well controlled by regular use of eye drops. In addition to the elevated IOP, the inflammation of the anterior segment and corneal stroma was found. Before cataract surgery, bilateral corneal opacities was revealed, but after cataract surgery, interstitial keratitis in both eyes was gradually aggravated, during the follow-up period from 2019 to 2021. She informed us that she had suffered from decreased vision in both eyes and was diagnosed with bilateral keratitis and congenital syphilis at the age of 20. In 2018, the serologic test for syphilis was positive in blood (Chemiluminescence analysis (CLIA): + ; Toluidine red unheated serum test (TRUST): + , titer was 1:1). However, four tests for TRUST were negative in 2019 and 2020, so she was not treated for syphilis.ConclusionThis case of glaucoma and interstitial keratitis might be secondary to ocular inflammation caused by late congenital syphilis. The ocular inflammation and the activation of syphilis may be related to cataract surgery.

Weathering the storm: a single-institution experience with paroxysmal sympathetic hyperactivity after brain tumor resection in pediatric patients.

Paroxysmal sympathetic hyperactivity (PSH) is a complication of severe traumatic or hypoxic brain injury characterized by transient episodes of tachycardia, tachypnea, hypertension, hyperthermia, diaphoresis, and/or dystonic posturing. Posttraumatic "sympathetic storms" are associated with poor outcomes. PSH rarely occurs after brain tumor resection in pediatric patients; only 4 cases have been published since 1929. Thus, the authors sought to report their experience with postcraniotomy PSH in pediatric brain tumor patients. A retrospective study of patients younger than 18 years of age who underwent craniotomy for brain tumor resection at a single center by a single surgeon over a 7-year period was performed. A clinical diagnosis of postoperative PSH was recorded. Recorded outcomes included the interval between surgery and initiation of cytotoxic therapy, need for long-term CSF diversion, length of hospital stay, and survival. Of the 150 patients who were included for analysis, 4 patients were diagnosed with postoperative PSH for an overall occurrence of 2.7%. PSH patients were younger than non-PSH patients (1.8 ± 0.4 years vs 9.2 ± 5.3 years, p = 0.010) and tended to have intraventricular tumors close to the thalamus, basal ganglia, and/or brainstem. PSH patients experienced longer hospital admissions (44.3 ± 23.4 days vs 6.8 ± 9.4 days, p = 0.001), a shorter interval between surgery and initiation of cytotoxic cancer-directed therapy (14.3 ± 8.0 days vs 90.7 days ± 232.9 days, p = 0.011), and increased need for long-term CSF diversion compared with non-PSH patients (75% vs 25%, p = 0.005). At the last follow-up, 50% of PSH patients had died compared with 13% of non-PSH patients (p = 0.094). PSH is a rare postoperative complication that may affect young children with periventricular tumors and is associated with poorer clinical outcomes. Increasing awareness of this condition is vital to improving patient outcomes.

Refinement of the open surgical technique has led to improved outcomes and morbidity profiles for this procedure over the past two decades. As techniques continue to evolve in hopes of improving surgical morbidity, contemporary reporting of the current standard of care is increasingly important. Thus, we report current perioperative outcomes and short-term complication rates for open virgin retroperitoneal lymph node dissection (O-VRPLND), with analysis of risk factors for complications in a consecutive single-institution series. METHODS: The institutional Indiana University Testicular Cancer database was utilized to identify all patients that underwent O-VRPLND over the study period (2018-2020). Demographic, perioperative, and pathologic variables were collected. Retrospective chart review was performed. Short term complications were graded using the Clavien-Dindo classification. The primary outcomes of interest were the contemporary preoperative profile of patients undergoing O-VRPLND, overall complication rates, and identification of risk factors associated with any complication. RESULTS: During the study period 165 patients were identified. Median BMI was 28.6, with a median ASA III classification. The majority (63.6%) of patients underwent O-VRPLND for non-seminomatous germ cell tumors compared with 30.9% for seminomas; patients were most often clinical stage IIA (39%) or IIB (36%) at the time of surgery. Median estimated blood loss (EBL) was 150cc, with no transfusions required. Among all preoperative and intraoperative variables, only BMI demonstrated significant association with development of any postoperative complication (mean BMI of 34.46 for patients with any complication, versus 28.94 for patients with normal recovery; p=0.0042). Median hospital stay was 3 days. Overall complication rate was low (8.48%), with one major postoperative complication and no deaths in the 30-day period. CONCLUSIONS: Open virgin RPLND has an acceptable morbidity profile, even among a cohort of predominantly overweight young patients with high ASA scores. Low EBL, short hospital stay, low 30-day readmission rate, and rare major postoperative complications may reflect the new benchmark for virgin RPLND.

Long-term follow up and comparison between conservative and interventional therapy in postoperative bronchopleural fistula-a cohort study.

Bronchopleural fistula (BPF) is a relatively rare postoperative complication with high mortality. The management is tough and controversial. The aim of this study was to compare the short and long-term outcomes between the conservative and the interventional therapy in postoperative BPF. We also concluded our own strategy and experience of treatment in postoperative BPF. Postoperative BPF patients with malignancies, aged from 18 to 80 years old who had undergone thoracic surgery between June 2011 and June 2020, were included in this study and followed up from 20 months to 10 years. They were retrospectively reviewed and analyzed. Ninety-two BPF patients were included in this study, 39 of whom underwent interventional treatment. Significant differences were found in the 28-day and the 90-day survival rates between the conservative and the interventional therapy (P=0.001, 43.40% vs. 76.92%; P=0.006, 35.85% vs. 66.67%). Simple conservative therapy was independently associated with 90-day mortality between the groups in postoperative BPF [P=0.002, hazards ratio (HR) =2.913, 95% confidence interval (CI): 1.480-5.731]. Postoperative BPF is notorious for its high mortality. Surgical and bronchoscopic interventions are recommendable in postoperative BPF as they guarantee better short and long-term outcomes compared with the conservative therapy.

Postoperative bone graft migration into the thecal sac and shifting down to the lower level after an endoscopic lumbar interbody fusion: a case report

BackgroundPostoperative bone graft migration (PBGM) is a fairly rare spinal postoperative complication. Its occurrence after endoscopic surgery has rarely been reported in the literature so far. This is a case report of a 52-year-old male occurring PBGM into the thecal sac in the 8th days after an endoscopic lumbar interbody fusion (ELIF), which can make surgeons more minded with such serious rare complication after BGM.Case PresentationA 52-year-old male patient, underwent a L4-5 ELIF, presented with an acute radiculopathy on right leg and urinary incontinence in the 8th postoperative day. An emergency lumbar Computed Tomography(CT scan) and Magnetic Resonance Imaging (MRI) demonstrated bone graft migration into the thecal sac at the L4-5 level, and shifting down to the lower level. The revision surgery was performed at once successfully. Finally, the patient got well managed before discharge.ConclusionSupported by this case report, we believe that PBGM into the thecal sac is a rare but horrible complication of ELIF. However, too much volume of bone graft and its posterior placement are more prone to developing this complication. Finally, we are not sure that the outcome presented in this study will be repeated in future cases.

Inner ear barotrauma: A case report of rare post-operative complication following robot-assisted radical prostatectomy.

To highlight a rare case of inner ear barotrauma as a post-operative complication following robot-assisted radical prostatectomy (RARP). A 65-year-old man diagnosed with localised prostate carcinoma underwent elective RARP in a steep Trendelenburg position. Postoperatively, the patient complained of bothersome dizziness and spinning of surroundings associated with nausea. The patient was diagnosed to have vestibular symptoms secondary to inner ear barotrauma. He was started on prochlorperazine 12.5 mg and antibiotics, following which the patient improved. Vestibular rehabilitation exercises were taught to the patient. After 3 days of treatment, the patient did well with no episodes of dizziness. The patient was discharged on tablet cinnarizine 25 mg thrice daily for a week. On follow-up, the patient is asymptomatic. Inner ear barotrauma can be a rare complication of a combination of prolonged steep Trendelenburg during robotic surgery and pneumoperitoneum. Only further reporting of such incidents can help determine predisposing factors and precautions for preventing such incidents.

Post-operative tension spinal subdural extra-arachnoid hygroma of the lumbar spine: case series, literature review, and recommendations for clinical management

Objective Case series presentation and literature review of patient group suffering from symptomatic tension subdural extra-arachnoid hygroma following decompressive surgery for degenerative lumbar stenosis or disc disease. The purpose was to better understand this rare post-operative complication with a pathognomic radiological sign to help recommend optimal strategies for clinical management. Methods Retrospective case series comprising seven cases from one tertiary Neurosurgical centre spanning a 10-year period from 2011 to 2021. Patients included were those known to have undergone a spinal procedure and subsequently to have developed a symptomatic spinal subdural extra-arachnoid hygroma (SSEH). A literature review was conducted using PubMed, MEDLINE and EMBASE (keywords ‘subdural hygroma’, ‘lumbar CSF hygroma’, ‘extra arachnoid hygroma’, ‘extra-arachnoid CSF collection’, ‘CSF tension hygroma’, ‘lumbar extra arachnoid hygroma’, ‘lumbar spinal hygroma’, ‘post-operating spinal hygroma’, ‘post-operative spinal CSF collection’) and through reading references cited in relevant articles. Articles involving post-operative SSEH following lumbar spinal surgery were included. Results Rare complication with only five other cases in the literature. Dural breach described intra-operatively in only 5 of 12 total cases from our series and the literature. 5 patients in our series were managed surgically with 2 being managed conservatively. All patients in our series improved symptomatically and radiologically following surgical or conservative management. Conclusions This is a rare post-lumbar surgery complication that can cause rapidly deteriorating lower limb and sphincteric function. Surgical management with wide durotomy and arachnoid marsupialisation can lead to reversal of neurological deterioration and excellent clinical results. A delayed presentation with pseudomeningocele formation may be managed conservatively if neurology is stable or improving. It is a condition that it is important for the clinician to recognise in order to instigate appropriate management in a time-dependent fashion.

Postoperative complications and critical care management after cytoreduction surgery and hyperthermic intraperitoneal chemotherapy: A systematic review of the literature.

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is a comprehensive treatment option performed for peritoneal surface malignancies. Postoperatively almost all patients are transferred to the intensive care unit electively. To describe the common and rare postoperative complications, postoperative mortality and their critical care management after CRS-HIPEC. The authors assessed 54 articles for eligibility. Full text assessment identified 14 original articles regarding postoperative complications and critical care management for inclusion into the final review article. There is an exaggerated metabolic and inflammatory response after surgery which may be termed as physiological in view of the nature of surgery combined with the use of heated intraperitoneal chemotherapy with/out early postoperative intravenous chemotherapy. The expected postoperative course is further discussed. CRS-HIPEC is a complex procedure with some life-threatening complications in the immediate postoperative period, reported morbidity rates between 12%-60% and a mortality rate of 0.9%-5.8%. Over the years, since its inception in the 1980s, postoperative morbidity and survival have significantly improved. The commonest postoperative surgical complications and systemic toxicity due to chemotherapy as reported in the last decade are discussed. CRS-HIPEC is associated with a varying rate of postoperative complications including postoperative deaths and needs early suspicion and intensive care monitoring.

Expanding perigraft seroma after ascending aorta replacement

BackgroundPerigraft seroma is a persistent and sterile fluid confined within a fibrous pseudomembrane surrounding a graft that develops after graft replacement. Development of perigraft seroma is an uncommon complication that occurs after the surgical repair of the thoracic aorta using woven polyester grafts. mechanism underlying perigraft seroma formation remains unclear.Case presentationHerein, we describe the case of 77-year-old man who underwent repeat sternotomy for the treatment of large perigraft seroma 1 year after ascending aorta replacement for acute type A dissection. After removing a cloudy yellow fluid, we covered the prosthetic graft with fibrin glue and wrapped it with a new graft. Bacterial culture and laboratory examination of the fluid confirmed the final diagnosis of perigraft seroma, and there was no evidence of recurrence. The area in which fluid accumulated around the graft shrunk 1 year after surgery.ConclusionsThe cause of a expanding perigraft after repair of the thoracic aorta remains unknown. Physicians should be aware that chronic expanding mediastinal seroma with Dacron grafts is one of the rare postoperative complications of thoracic aortic surgery. Applying fibrin glue to the graft surface might effectively prevent the recurrence of perigraft seroma.

HYPOCALCAEMIC CARDIOMYOPATHY AFTER PARATHYROIDECTOMY IN A PATIENT WITH TURNER SYNDROME: A CASE REPORT

Hypocalcaemic cardiomyopathy is a rare postoperative complication after hemi-parathyroidectomy which reverses completely on the restoration of normocalcaemia. Patients of Turner syndrome have subtle cardiovascular anomalies due to the underlying oestrogen deciency. A 16-year-old female patient with Turner syndrome underwent hemi-parathyroidectomy for parathyroid adenoma. The patient developed signs of heart failure on postoperative day two, which was precipitated by tachycardia due to fever. She developed tachycardia, tachypnoea, hypertension, and pulmonary oedema with an ejection fraction of 20-30% at the time without any underlying cardiac disease. The patient was managed with intravenous diuretics, beta-blockers, and non-invasive ventilation. Other probable causes such as sepsis, pheochromocytoma, thyrotoxicosis, and Takotsubo syndrome were ruled out. A differential diagnosis of hypocalcaemic cardiomyopathy was suspected, and the patient was given intravenous calcium and vitamin-D supplementation. The patient responded promptly to restoration of normocalcaemia, and the cardiomyopathy reversed completely. Echocardiography done on follow-up showed normal ejection fraction.

Postoperative hematoma can be a risk factor in delayed facial palsy after vestibular schwannoma resection via a retrosigmoid approach: a retrospective single-center cohort study.

Delayed facial palsy (DFP) is a rare postoperative complication after vestibular schwannoma (VS) surgery. The exact mechanism of DFP remains uncertain and the risk factors for DFP are still controversial. The authors aimed to investigate the characteristics, risk factors, and etiology of DFP after VS resection retrospectively. Ninety-one consecutive surgeries with VS were analyzed. Patients with neurofibromatosis 2 in eight surgeries and postoperative facial palsy House-Brackmann (HB) grade more than 3 in two surgeries were excluded. Eighty-one surgeries were included in this research. Facial nerve function was evaluated using the HB grade. Delayed facial palsy was defined as deterioration in the facial function of at least 1 HB grade more than 1day after undergoing VS resection. The characteristics of patients with VS and risk factors for DFP were analyzed. All surgeries were performed via a retrosigmoid approach. DFP was observed in nine patients. There were no statistically significant differences between the DFP group and non-DFP group in terms of the following characteristics: sex, age, side, size, Koos grading system, postoperative facial palsy, or extent of resection. Postoperative hematoma in the cerebellopontine angle (CPA) cistern was significantly higher in the DFP group than in the non-DFP group (p = 0.0023), and was significantly associated with DFP after VS surgery (odds ratio 18.40, p < 0.001). DFP improved in seven patients, but two patients did not improve. DFP occurred in 11.1% of patients after VS surgery. This study revealed that postoperative hematoma in the CPA cistern was significantly associated with DFP after VS surgery.
