RESUMO

A 47-year-old male presented with a right-sided Shamblin type 2 carotid body tumor measuring 5*5 cm. After preoperative embolization, a sub adventitial resection of the tumor was done. He was discharged after postoperative day 5 and presented again to emergency 10 days later with a bleeding pseudoaneurysm at the surgical site causing dysphagia and dyspnea. He was taken for emergency exploration of the surgical wound and, intraoperatively, it was observed that the proximal ends of the internal carotid artery and external carotid artery close to the bifurcation were forming a pseudoaneurysm, 1 cm distal to the common carotid artery. The external carotid artery was ligated and a common carotid to internal carotid artery bypass was done with a reversed saphenous vein graft. He recovered well in the postoperative period and was discharged on day 7. Pseudoaneurysm formation following carotid body tumor resection is extremely rare and has only been reported thrice in the literature.


Um homem de 47 anos apresentou tumor carotídeo Shamblin tipo 2 no lado direito, medindo 5 x 5 cm. Após embolização pré-operatória, foi realizada ressecção subadventicial do tumor. O paciente teve alta no quinto dia pós-operatório e voltou à emergência 10 dias depois, com pseudoaneurisma hemorrágico no sítio operatório causando disfagia e dispneia. Foi levado para exploração emergencial da ferida cirúrgica, e, no intraoperatório, 1 cm distalmente à artéria carótida comum, as extremidades proximais da artéria carótida interna e da artéria carótida externa próximas à bifurcação formavam um pseudoaneurisma. A artéria carótida externa foi ligada, e foi realizada uma ponte de safena de carótida comum para a artéria carótida interna com a veia safena invertida. O paciente se recuperou bem no pós-operatório e recebeu alta no sétimo dia. A formação de pseudoaneurisma após ressecção de tumor do corpo carotídeo é extremamente rara, tendo sido relatada apenas três vezes na literatura.

RESUMO

Introduction: Insulinomas are rare, usually sporadic, and typically benign pancreatic neuroendocrine tumours. Pre-operative localization is challenging and evidence on comparative analysis of anatomic and scintigraphic modalities for pre-operative tumour localization is limited, even in contemporary series. Methods: The current study was designed to study the clinical features and management challenges of insulinomas managed at a tertiary care centre. Clinical features, diagnosis, imaging techniques, surgical procedures, and outcomes details were collated. Pre-operative imaging techniques (CT/MRI, nuclear scintigraphy) were compared with intraoperative and histopathological findings to assess their accuracy of localization. Results: Thirty-seven patients (15 females [42%]; median age 36 years [IQR 28-49]) were included in the study. In four patients (10.8%), the tumour occurred in the setting of multiple endocrine neoplasia type 1 (MEN 1) while the remaining were sporadic. The sensitivity of pre-operative localization was 61.5% (multiphasic CT), 66.6% (multiphasic MRI), 100% (68Ga Exendin-4 PET-CT), and 91.6% (EUS). Three patients with normal multiphasic CT had localization on 68Ga Exendin-4 PET-CT. The positive predictive value (PPV) of both Exendin-PET-CT and EUS was similar at 91.6% and 91.6%, respectively. All patients (except one with nesidioblastosis), who underwent enucleation or partial pancreatic resection, were cured. Conclusion: 68Ga Exendin-4 PET-CT based is a non-invasive imaging modality that has high sensitivity and PPV and can be used as a first-line imaging modality. The overall prognosis of these tumours is good with high cure rates attained following surgical resection.

RESUMO

Dermatofibrosarcoma protuberans (DFSP) is an aggressive tumour with multiple local recurrences and rare metastatic potential. Fibrosarcomatous transformation occurs in a few cases of DFSP which makes them more aggressive in terms of recurrence and metastasis. Here we report the case of a woman in her late 30s who presented with massive lower gastrointestinal (GI) bleeding with a history of multiple surgeries for DFSP on her anterior abdominal wall. The bleeding source was identified to be a mass lesion in the jejunum, which was excised. The patient recovered well and the histopathology revealed fibrosarcoma of the jejunum. Follow-up investigations showed multiple lung nodules, ascites and abdominal lymph nodes suggesting progressive disease. She is currently receiving chemotherapy and progressing well 3 months postoperatively. Patients with fibrosarcomatous changes within DFSP must be followed up closely as it is associated with increased metastatic potential.

RESUMO

INTRODUCTION: Extracranial carotid artery (CA) pseudoaneurysms are uncommon and can cause embolic stroke, compressive symptoms, or (rarely) can rupture. It is of paramount importance to treat this entity to avoid life-threatening complications. In this study, the authors described a cohort of patients that required open surgical repair. METHODS: This article reported the authors' experience with open surgical repair of extracranial CA pseudoaneurysms by presenting a retrospective review of data at their institution from 2016 to 2022. RESULTS: Of 8 patients that underwent open repair, 6 were male and 8 were female. The most common etiology was traumatic (penetrating trauma in 4 patients, iatrogenic injury in 2, and blunt trauma in 1) and 1 was infective. All patients presented with a neck mass, and 5 had compressive symptoms. Primary repair was performed in 4 patients, interposition graft using an autologous vein in 2, and patch repair in 2. None of the patients experienced perioperative mortality or stroke; nor did they develop any complications over a median follow-up period of 30 months. CONCLUSION: This report demonstrated that large-size extracranial pseudoaneurysms, whether traumatic or infective etiology, can be safely repaired using an open surgical approach.

RESUMO

Advanced and metastatic gastrointestinal stromal tumors (GISTs) presenting with surgical emergencies are rare. Neoadjuvant imatinib being the treatment of choice for non-metastatic advanced disease with a proven role in downstaging the disease may not be feasible in patients presenting with bleeding and obstruction. We present a case series with retrospective analysis of a prospectively maintained database of patients with advanced and metastatic GISTs presenting with surgical emergencies. Clinical characteristics, imaging and endoscopic findings, surgical procedures, histological findings, and outcomes in these patients were studied. Four patients were included in this case series, with three males and one female (age range: 24-60 years). Two patients presented with melena; one with hemodynamic instability despite multiple blood transfusions underwent urgent exploratory laparotomy for bleeding gastric GIST, while the other underwent surgical exploration after careful evaluation given the recurrent, metastatic disease with a stable metabolic response on six months of imatinib. One patient with metastatic jejunal GIST who presented with an umbilical nodule and intestinal obstruction was given a trial of non-operative management for 72 hours, but due to non-resolution of obstruction, segmental jejunal en bloc resection with the dome of the urinary bladder with reconstruction and metastasectomy was needed. The patient with advanced gastric GIST who presented with gastric outlet obstruction was resuscitated, and an attempt of endoscopic naso-jejunal tube placement was tried, which failed, and exploration was needed. The mean length of hospital stay was 7.5 days. Histopathological examination confirmed GIST in all four patients with microscopic negative resection margins. All patients were started on imatinib with dose escalation to 800 mg in the patient with recurrent and metastatic disease; however, the patient with bleeding gastric GIST experienced severe adverse effects of imatinib and discontinued the drug shortly. All four patients are disease-free on follow-ups of 15 months, 48 months for the patient with advanced non-metastatic disease, and six and 24 months for the patients with metastatic disease. In the era of tyrosine kinase inhibitor (TKI) therapy for advanced and metastatic disease, upfront surgery is usually reserved for surgical emergencies only. Surgical resection, the cornerstone for the treatment of resectable GIST, may also be clinically relevant in metastatic settings, although it requires a careful and individualized approach.

RESUMO

BACKGROUND: Strain echocardiography is a highly sensitive modality for detecting myocardial disease at an early stage. Therefore, we aim to evaluate subclinical left ventricular dysfunction in primary hyperparathyroidism (PHPT) patients with myocardial strain imaging in addition to conventional echocardiography and to look for its reversal after parathyroidectomy (PTx). METHODS: Thirty patients who underwent curative parathyroidectomy for PHPT were included. All patients were evaluated with M mode echo, 2D echo and strain imaging before and 6 months after PTx. Left ventricular ejection fraction, left ventricular diastolic dysfunction, left ventricular hypertrophy (LVH), Global Longitudinal Strain (GLS) and global circumferential strain (GCS) were recorded. RESULTS: On M mode echo, LVH was present in 15 patients and 8 of them improved completely after PTx (p < 0.038). Incidence of systolic and diastolic dysfunction on 2D echo was 10% and 13.3% respectively; while myocardial strain imaging showed impaired systolic function in 46.7% patients. Hence, compared to conventional 2D echo, strain imaging showed 36.7% high detection rate of subnormal cardiac function. There was improvement in left ventricle dysfunction (p = 0.083), GLS and GCS (p = 0.034) after PTx. Serum parathormone demonstrated a strong positive correlation with change in GLS and GCS (p = 0.013, p = 0.126) while serum calcium showed a weak correlation with change in GLS and GCS following surgery. CONCLUSION: Myocardial strain imaging should be considered for all PHPT patients as early identification of subclinical ventricle dysfunction provides an opportunity for an early intervention and thereby preventing development of irreversible LV dysfunction.

RESUMO

Post-liver transplant (LT) hepatic artery vasospasm is a vascular complication that is not well recognized and its incidence is not known. As a possible sequela to vasospasm, hepatic artery thrombosis is the second major cause of allograft failure after primary nonfunction and its reported incidence is 2.9% in adults and 8.3% in pediatric LT. Lacuna in knowledge regarding early hepatic artery vasospasm post-LT makes it a difficult condition to diagnose and treat, as the initial ischemic insult on graft can have devastating consequences. We report a case of pediatric progressive familial intrahepatic cholestasis type 3-related chronic liver disease who underwent cadaveric orthotopic LT and postoperatively developed fever, worsening hypotension, and elevated liver enzymes with an absence of arterial flow in intrahepatic branches on Doppler ultrasound. Suspecting early hepatic artery thrombosis, the patient was re-explored and the graft hepatic artery was found to be in a state of vasospasm. Following the infusion of intra-arterial papaverine, urokinase, and intravenous nicorandil, there was an improvement in blood flow. The patient responded well and was discharged on postoperative day 23 with normal liver enzymes.

RESUMO

OBJECTIVE: Chronic venous disease (CVD) is accompanied by a spectrum of skin changes. The aim of this study was to assess skin changes in CVD in different classes of the classifications such as the Clinical-Etiology-Anatomy-Pathophysiology (CEAP) classification using ultrasound (US). METHODS: This study was conducted from July 2020 to July 2021 after obtaining approval from Institutional Ethical Committee. Patients with chronic venous insufficiency were enrolled after taking informed consent. Assessment of cutaneous layer (CL), subcutaneous layer (SCL), dermo-hypodermal junction (D-HJ), and other significant US findings were noted. RESULTS: Ninety-eight limbs were evaluated. Most common skin finding was dermal edema in 59 (60.2%) legs. Other findings included infiltrates, CL thickening, hyper echogenicity and thickening of SCL, anechoic lacunae, disappearance of D-HJ, and epidermal loss or change in thickness of epidermis. Notably, US detected dermal edema in 15 and infiltrates in five C2 legs (normal on inspection). CONCLUSION: US evaluation of skin changes adds insight to clinical assessment and may reveal skin changes in legs affected with CVD that may appear normal on clinical examination.

RESUMO

OBJECTIVE: Chronic mesenteric ischemia (CMI) is a rare, debilitating disease associated with higher morbidity and mortality if not treated on time. In the past two decades, there has been a paradigm shift in its management with endovascular modality due to reduced perioperative morbidity and mortality. In the endovascular era, only a few patients require surgical therapy. We conducted this study to report our experience with open surgical revascularization at our hospital. METHODS: We have conducted a retrospective study after obtaining approval from Institutional Ethics Committee. Data regarding patients who underwent open revascularization for CMI with long-segment occlusion from 2016 to 2021 has been retrieved from the institutional database. The demographic data, clinical presentation, type of surgery and graft used, perioperative mortality and morbidity and length of hospital stay were evaluated. Overall survival and disease-free survival were assessed using Kaplan-Meier analysis. RESULTS: Twenty-one patients underwent open surgical revascularization; 16 were males and five females. The median age was 43 years. Fourteen (66.7%) were smokers. The mean duration of follow-up was 28.4 ± 13.6 months. Thirty-day postoperative mortality was 0% and morbidity was 28%. The average duration of hospital stay and postoperative weight gain were 6.9 ± 3.7 days and 11 ± 4.9 kgs, respectively. One patient died at two years of follow-up due to myocardial infarction and one had a recurrence. Long-term survival at 60 months of follow-up was 91.6% and the primary-patency rate was 95.2%. CONCLUSION: Owing to better long-term and reintervention-free patency, open revascularization should be considered in patients who are fit for surgery, particularly in patients with long-segment mesenteric artery occlusion.

RESUMO

BACKGROUND: Postoperative nausea and vomiting (PONV) causes an unexpected prolonged hospital stay after ambulatory surgery. Novel measures such as preoperative loading of oral carbohydrates and postoperative chewing gum have recently gained momentum for postoperative recovery. This study evaluated the effects of preoperative carbohydrate loading and postoperative chewing gum (CG) on PONV after daycare laparoscopic cholecystectomy (LC). METHODS: A total of 100 patients were randomized to group A (preoperative carbohydrate loading with 200 ml of water with 25 g of carbohydrate and postoperative chewing gum (CG) when the patient responded to his/her name) and group B (standard care). The incidence of PONV and pain was assessed by using visual analogue scale. Quality of recovery (QoR-15) was assessed by using QoR15 questionnaire at 6 h, 24 h and 48 h after surgery. RESULTS: The incidence of PONV and pain was lower in group A; however, it was not significant (p > 0.05). The severity of PONV, pain and the need for rescue antiemetic was significantly lower in group A (p < 0.05). The episodes of PONV and required dose of antiemetic were less in group A. Group A also had a significantly higher QoR-15 score at all time points (p < 0.001). Preoperative dyspepsia was also noticed as a significant confounding predictor for postoperative vomiting. CONCLUSION: Preoperative carbohydrate drinks and early postoperative CG reduces the severity of PONV and requirement of antiemetics in patients undergoing LC. Hence, these simple measures can be used as a standard of care to optimize perioperative care in patients undergoing daycare surgery.

RESUMO

The continuous cell line of epithelial human parathyroid cells has been proven difficult. Previously, PTH-C1 cell line was only established rat parathyroid tissue cell line known to express the parathyroid hormone-related peptide (Pthrp) gene. The paucity of continuous cell line of human parathyroid cells secreting parathyroid hormone (PTH) has imposed hurdle in in vitro assessment of the mechanisms involved in the control of parathyroid cell function and proliferation. The primary cell cultures of human parathyroid cells were derived from parathyroid adenoma tissue biopsy (n = 5). The cells were subsequently subcultured to maintained primary subclones. Karyotyping analysis was performed to analyze the genotypic identity of derived subclones. The expression of calcium-sensing receptor (CaSR) and intact parathyroid hormone (iPTH) were analyzed using immunocytochemistry and immunofluorescence. In the present study, we have used a defined condition medium to generate the continuous culture of human parathyroid cells derived from patients with parathyroid adenoma due to primary hyperparathyroidism. The subcultured primary subclones were maintained epithelial and polygonal morphology, doubling time of approximately 25 h, displaying a diploid chromosome number, and secretion of PTH. This cell line produces PTH and expresses the calcium-sensing receptor (CaSR) known to be involved in parathyroid function. Altogether these findings indicate the uniqueness of the human parathyroid cell line as an in vitro model for cellular and molecular studies on parathyroid physiopathology.

RESUMO

INTRODUCTION: Obesity is associated with increased morbidity and mortality post surgery. The measurement of visceral obesity can predict postoperative outcomes after pancreaticoduodenectomy. METHODS: This is a prospective observational study. Visceral obesity was calculated by measuring the fat thickness in the retro-renal area by using a computed tomography scan. Visceral obesity was defined as retro-renal fat thickness (RRFT) of ≥ 2 cm. Patients were divided into two groups: Group-A (RRFT < 2 cm, non-obese) and Group-B (RRFT > 2 cm, obese). Demographic, clinical, and intraoperative variables were correlated with postoperative outcomes. RESULTS: Fifty-six patients were included in the study. Thirty-two patients were included in Group-A, and 24 patients were included in Group-B. The two groups had comparable outcomes. A total of 21 patients in Group-A (65.62%) and 17 patients in Group-B (70.83%) had comorbidities, including diabetes mellitus, hypertension, and coronary disease (p=0.680). American Society of Anesthesiologists (ASA) grading was comparable (p=0.927). BMI was also comparable (p=0.354). Type of pancreaticoduodenectomy, pancreatic texture, pancreatic duct diameter, and technique of pancreaticojejunostomy anastomosis were comparable. The mean operative time was longer in Group-B (362 ± 36.2 min vs. 298 ± 45.2 min) (p=0.001). Intraoperative blood loss was more in Group-B (312 ± 36.8 ml vs. 267 ± 23.7 ml) (p=0.001). The rates of postoperative pancreatic fistula and delayed gastric emptying were comparable (p=0.402 and p=0.134, respectively). The length of hospital stay was longer in patients in Group-B (p=0.004). There was one death in Group-B (obese group). CONCLUSION: Visceral obesity is a risk factor for postoperative complications after a pancreaticoduodenectomy.

RESUMO

Purpose: Adrenocortical carcinoma (ACC) is a rare and highly aggressive malignant neoplasm, usually diagnosed in advanced stage. Role and efficacy of adjuvant radiotherapy has not been well defined. The objective of this study is to describe the various clinical characteristics and prognostic factors affecting the survival of ACC along with the role radiotherapy on overall survival and relapse free survival. Methods: A retrospective analysis of 30 patients registered between 2007 and 2019 was carried out. The medical records containing clinical and treatment details were analysed. Data was analysed using SPSS 25.0. Survival curves were computed using Kaplan-Meier method. Univariate and multivariate analyses were performed to analyze the prognostic factors affecting the outcome. A p value of less than 0.05 was considered to be statistically significant. Results: The median age of patients was 37.5 years (range, 5-72 years). 20 patients were females. Twenty-six patients had advanced stage (III/IV) disease while only four patients presented in early stage. Twenty-six patients underwent total adrenalectomy. Eighty three percent patients received adjuvant radiation therapy. The median follow up was 35.5 months (range, 7 monthss-132months). The estimated three- and 5-years overall survival (OS) was 67.2% and 23.3%, respectively. Capsular invasion and positive margins were the independent prognostic factors influencing both OS and relapse free survival (RFS). Out of 25 patients who received adjuvant radiation, only three patients had local relapse. Conclusion: ACC is a rare and aggressive neoplasm with majority of patients presenting in advanced stage. Surgical resection with negative margins remains the mainstay of treatment. Capsular invasion and positive margins are independent prognostic factors for survival. Adjuvant radiation reduces the risk of local relapse and is well tolerated. Radiation can be used effectively in adjuvant and palliative settings in ACC.

RESUMO

Introduction Chronic venous insufficiency is a major cause of morbidity, and there is a paucity of data regarding its epidemiology due to the lack of a central wound registry. In this study, we aimed to study the time for healing of the ulcer and compliance with compression therapy (CT) following endovenous laser ablation (EVLA) ± ultrasound-guided foam sclerotherapy (UGFS) along with CT in patients with chronic venous ulcers. Methods This prospective observational study was conducted from January 2020 to June 2021 after obtaining institutional ethical committee clearance. Patients with chronic venous ulcers (>six weeks to 4 cm in 10% of patients. A total of 38% of patients underwent only EVLA, and EVLA+UGFS were done in 62% of participants. The healing rate at six months follow-up was 92%, with the average time taken being 2.55±1.38 months. Those who remained with an unhealed ulcer at six months follow-up had an ulcer size of >5 cm and an age of >50 years. Ninety-six percent of the patients were compliant with CT after an endovenous intervention. The recurrence rate at two years post-ablation was 6%. VCSS was 19.66±3.23 at presentation and 5.5±2.82 at six months of follow-up. Conclusion Endovenous ablation of superficial venous reflux along with CT is associated with a shorter healing time of venous ulcerations and reduced chances of recurrence. There is an improvement in VCSS score over the period of six months follow-up.

RESUMO

Primary hepatic angiosarcoma (PHA) is a rare, rapidly growing, highly aggressive hepatic malignancy, primarily seen in elderly males. Establishing an accurate clinical diagnosis is challenging owing to its rarity and nonspecific presentation. Rendering a cytologic diagnosis of PHA is extremely difficult, and immunocytochemistry(ICC) on cell block(CB) sections is essential to confirm the diagnosis. The characteristic cytomorphologic features of PHA have rarely been documented, further augmenting the diagnostic challenge. A 32-year-old male presented with abdominal pain, abdominal distension, and significant weight loss over the past 9 months. On examination, the abdomen was distended, with multiple spider angiomas and a large mass in the right hypochondrium. His renal function tests, liver function tests, and serum tumor markers were within normal limits. An abdominal triphasic computerized tomography revealed a large lobulated mass in the right lobe with central necrosis. An ultrasound-guided FNA was performed from the liver lesion. The cytologic smears showed singly scattered large, markedly pleomorphic, epithelioid-elongated tumor cells having oval-elongated nuclei, irregular nuclear contours, coarse chromatin, prominent macronucleoli, and abundant finely vacuolated cytoplasm in a background of blood. ICC on the CB demonstrated diffuse positivity for vimentin, CD31, and nuclear positivity for FLI-1, confirming a vascular origin. Hence, a final cytologic diagnosis of primary hepatic angiosarcoma was rendered. The index report describes the characteristic cytomorphologic and immunocytochemical features of a rare hepatic malignancy in a young male and reiterates the usefulness of FNAC coupled with CB-ICC in the quick and precise diagnosis of such challenging cases.
