Assessment of left ventricular dysfunction by strain echo in primary hyperparathyroidism and its reversal after parathyroidectomy.

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.

Outcomes of open revascularization for chronic mesenteric ischemia at a tertiary care center in India.

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.

Effect of Preoperative Carbohydrate Drink and Postoperative Chewing Gum on Postoperative Nausea and Vomiting in Patients Undergoing Day Care Laparoscopic Cholecystectomy: A Randomized Controlled Trial.

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.

A Young Adult Presenting With an Abdominal Aneurysm Due to Cystic Medial Necrosis of the Aorta.

Cystic medial necrosis is a disorder of large arteries, particularly the thoracic aorta, characterized by an accumulation of a basophilic ground substance in the media with cyst-like lesions. A male in his late 20s was brought to our trauma bay after he met with a road traffic accident with a complaint of abdominal pain. Clinical examination revealed tenderness in the left lumbar region. The contrast-enhanced computerized tomography revealed an aneurysm of size 11×9.6×9.2 cm in the left lateral aspect of the abdominal aorta at the origin of the left renal artery. Intraoperatively, an aneurysm of size 10×10 cm from the juxta renal abdominal aorta was identified, and aortic rent was repaired with a polyester graft. The tissue was sent for histopathology, which showed complicated atherosclerosis with cystic medial degeneration and aneurysmal rupture of the abdominal aorta containing thrombus. The patient had an uneventful postoperative course and is doing well without any complaints at a two-year follow-up.

Effect of intraperitoneal magnesium sulfate in the prevention of postoperative pain in daycare laparoscopic cholecystectomy - A prospective randomized controlled trial.

This study evaluated the efficacy of intraperitoneal magnesium sulfate (MgSO4) in preventing postoperative pain after elective laparoscopic cholecystectomy (LC). It is a prospective, double-blinded, placebo-controlled, randomized trial which included 64 patients who underwent LC. Patients were equally randomized into Groups A and B. MgSO4 and normal saline were instilled in subdiaphragmatic space in Groups A and B, respectively, after creating pneumoperitoneum and before starting dissection. The Visual analogue Scale (VAS) was used to determine postoperative pain. Patients who received intraperitoneal MgSO4 had lower average VAS scores for the first 6 h postoperatively, and also, the time for the requirement of first analgesic was longer (3.6 ± 0.4 vs. 2.3 ± 1.0 h). The incidence of vomiting and the requirement for rescue antiemetic was also lower in Group A. Intraperitoneal instillation of MgSO4 reduces postoperative pain and vomiting following elective LC without incurring additional side effects.

Correlation Between Tumor Volume and Hemoglobin Level in Gastrointestinal Stromal Tumor.

INTRODUCTION: Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors. Anemia is a common finding in GIST, but the relationship between tumor volume and anemia severity is not well established. METHODS: This study aimed to investigate the correlation between the severity of anemia and various factors, mainly tumor volume, in GIST patients who underwent surgical resection. The study included 20 patients with GIST who underwent surgical resection at a tertiary care center. Demographic data, clinical presentation, hemoglobin level, radiological findings, surgical procedure, tumor characteristics, pathological findings, and immunohistochemical analysis were recorded. The tumor volume was calculated from the final resected tumor dimensions. RESULTS: The mean age of the patients was 53.8 ± 12 years. Eleven were males, and nine were females. The most common presentation was upper gastrointestinal bleeding (50%), followed by pain in the abdomen (35%). The most common tumor location was the stomach (75%). The mean hemoglobin level was 10.29 ± 1.9 g/dL. The mean tumor volume was 470.8 ± 1269.07 cc. R0 resection was achieved in 18 (90%) patients. There was no significant correlation between tumor volume and hemoglobin level (r=0.227, p=0.358). CONCLUSION: This study found no significant correlation between tumor volume and the severity of anemia in patients with GIST. Further studies with larger sample sizes are needed to validate these findings.

Isolated external iliac artery aneurysm: a rare case presentation of IgG4-related disease / Aneurisma isolado de artéria ilíaca externa - uma apresentação de caso raro de doença relacionada à IgG4

Abstract Isolated external iliac artery aneurysm is a rare occurrence. These aneurysms have varied presentations depending on size and proximity. Both open surgical and endovascular modalities can be used for treatment depending upon presentation, aneurysmal anatomy, and patient condition. Preservation of at least one internal iliac artery is important to prevent post-repair hypogastric ischemia. There are no previous reports of IgG4-related disease (IgG4-RD) as etiology of these aneurysms. A 32-year-old male patient presented with a left lower abdominal lump and was found to have a left external iliac artery aneurysm on computed tomography angiography. The patient underwent iliofemoral bypass with an 8 mm polyester graft. Histopathological examination of the aneurysm wall suggested IgG4-RD. The patient fulfilled the 2020 Revised Comprehensive Diagnostic Criteria for IgG4-RD. An 18-Fluorodeoxyglucose-Positron Emission Tomography scan performed in the postoperative period showed no active disease, hence medical therapy was not instituted. The patient is doing well at 1 year.

Resumo O aneurisma isolado da artéria ilíaca externa é uma ocorrência rara. Esses aneurismas têm apresentações variadas, dependendo do tamanho e da proximidade. Ambas as modalidades cirúrgicas aberta e endovascular podem ser usadas para o tratamento, dependendo da apresentação, anatomia do aneurisma e condição do paciente. A preservação de pelo menos uma artéria ilíaca interna é importante para prevenir isquemia hipogástrica pós-reparação. A doença relacionada à imunoglobulina G4 (IgG4-RD) nunca havia sido encontrada como etiologia desse aneurisma. Um paciente do sexo masculino de 32 anos que apresentava um nódulo no abdome inferior esquerdo foi diagnosticado com aneurisma da artéria ilíaca externa esquerda na angiotomografia computadorizada. O paciente foi submetido a bypass iliofemoral com enxerto de poliéster de 8 mm. O exame histopatológico da parede do aneurisma era indicativo de IgG4-RD. O paciente cumpriu os Critérios Abrangentes Revisados ​​para IgG4-RD de 2020. A tomografia por emissão de pósitrons com 18-fluorodesoxiglicose no pós-operatório não evidenciou doença ativa, não sendo instituída terapia medicamentosa. Após seguimento de 1 ano, o paciente está bem.

Giant cephalic venous aneurysm.

The occurrence of venous aneurysms (VAs) is very rare, and VAs have been seldom reported in the existing literature. The etiology leading to the formation of VAs has not yet been determined. The presentation can range from asymptomatic to painful thrombosis of the sac, with rare events of pulmonary embolism. We have reported the case of a patient who had had a large cephalic vein aneurysm that was treated successfully. A 39-year-old man had presented with swelling in the left forearm that had progressively increased in size for 2 years and was associated with discomfort. On examination, a 5 × 5-cm soft compressible lesion was present over the mid-forearm that disappeared with raising of the arm. Contrast-enhanced magnetic resonance imaging showed a well-defined lesion arising from the cephalic vein. Under local anesthesia, after proximal and distal ligation, the aneurysm was excised. The histopathologic examination showed a thinned out smooth muscle wall and multifocal absence of the smooth muscle layer. The patient was doing well at 1 year of follow-up with no further degeneration in the vein wall. The formation of VAs might result from endophlebohypertrophy and endophlebosclerosis of the veins at the site of recurrent stress. Surgical excision should be considered when the patient is symptomatic, cosmetic disfigurement is present, and/or complications such as venous thrombosis, pulmonary embolism, and/or nerve compression have developed.

A Bull Gore Penetrating Injury to the Neck Presenting With Esophageal Perforation: A Case Report.

Bull gore injuries are not uncommon in regions where bulls are commonly used for agriculture or as part of sporting culture. Most bull gore injuries occur in the trunk and extremities. Cervical bull gore injury might be due to penetrating or blunt trauma. In the neck, it may injure vital structures such as the trachea, esophagus, and carotid artery. Traumatic cervical esophageal injury is a rare entity. Prompt diagnosis and early intervention are essential for better outcomes. Delayed diagnosis (>24 hours) is associated with a mortality of 40-66%. Here, we report a case of a bull gore injury to the neck where the patient presented to our trauma bay after seven days. On evaluation, he was diagnosed with cervical esophageal injury and treated with primary repair of the esophagus over a T-tube and a feeding jejunostomy. He recovered well and was doing well on follow-up.

Coarctation of the aorta in a young female treated with left subclavian artery to descending thoracic aorta bypass: a case report / Coarctação de aorta em jovem tratada com artéria subclávia esquerda para bypass de aorta torácica descendente: relato de caso

Abstract Coarctation of the aorta is a rare congenital abnormality, with an incidence of 6-8% of all congenital heart problems. It is usually diagnosed in childhood during routine clinical examination and adults mostly present with hypertension. Various investigations like transthoracic echocardiography, computed tomography, and magnetic resonance angiography can help with diagnosis. Prognosis depends on age at presentation and the severity of coarctation. Treatment options available are open and endovascular repair. Extra-anatomical bypass is the preferred option in cases with unfavorable anatomy. Long term follow up is required post repair due to risk of restenosis and aneurysm formation. Here is a case in which a young female presented with hypertension, was diagnosed with coarctation of the aorta, and was treated a left subclavian artery to descending thoracic aorta bypass. Her postoperative course was uneventful and she had improvement in hypertension.

Resumo A coarctação da aorta é uma anomalia congênita rara, com incidência de 6-8% entre todos os problemas cardíacos congênitos. É geralmente diagnosticada na infância durante o exame clínico de rotina, e os adultos normalmente apresentam hipertensão. Diversas investigações, como ecocardiografia transtorácica, tomografia computadorizada e angiorressonância magnética, podem auxiliar no diagnóstico. O prognóstico depende da idade na apresentação e da gravidade da coarctação. As opções de tratamento disponíveis são o reparo aberto e o reparo endovascular. O bypass extra-anatômico é a opção preferida em caso de anatomia desfavorável. O acompanhamento de longo prazo é necessário após o reparo devido ao risco de reestenose e formação de aneurisma. Descrevemos o caso de uma jovem do sexo feminino que apresentou hipertensão, a qual foi diagnosticada como coarctação da aorta. Foi realizada derivação da artéria subclávia esquerda para a aorta torácica descendente. O pós-operatório transcorreu sem intercorrências, e a paciente apresentou melhora da hipertensão.

Surgical outcome after focused parathyroidectomy: experience from a tertiary care centre in North India.

<b style="color: #075541"> Introduction:</b> Focused parathyroidectomy is the gold standard treatment for primary hyperparathyroidism (PHPT) due to single gland disease with a comparable success rate as that of conventional four gland exploration. It is also associated with fewer surgical complications. Despite these benefits, there is still controversy about the high recurrence following the focused approach. </br> </br> <b style="color: #075541">Aim:</b> The aim was to analyse our experience regarding the success rate of focused parathyroidectomy for PHPT. </br> </br> <b style="color: #075541">Methods:</b> This was a retrospective analysis of 192 patients of PHPT between January 2017 and August 2020 who underwent focused parathyroidectomy without intraoperative parathormone analysis, and had a minimum follow up of six months. Demographic profile, biochemical (pre and postoperative), radiological, operative and histological detail of all patients were recorded. Parathyroidectomy was considered curative if the patient maintained normal serum calcium and parathormone (PTH) levels six months after surgery. Persistent hyperparathyroidism was considered if hypercalcemia or high PTH levels persisted, or recurrent disease when a patient had rising serum calcium and / or PTH levels six months after curative parathyroidectomy. </br> </br> <b style="color: #075541">Results:</b> No patient had pain and wound-related complications after parathyroidectomy. Two patients had voice change in the immediate postoperative period which recovered subsequently; no patient had documented vocal cord paralysis. The persistent disease was present in two patients; both required neck exploration. Five patients had recurrence of PHPT within six months of parathyroidectomy; all of them had hyperplasia on the final biopsy. The overall cure rate was 97.92%. </br> </br> <b style="color: #075541">Conclusion:</b> Therefore, we propose focused surgery for sporadic PHPT should be considered as a preferred treatment with acceptable recurrence rate and surgical complications.</br> </br> <b style="color: #075541">KEYWORDS:</b>focused parathyroidectomy, parathyroidectomy, primary hyperparathyroidism.

Giant retroperitoneal lymph node-an uncommon presentation of duodenal neuroendocrine tumour.

Primary retroperitoneal neuroendocrine tumours (NETs) are extremely rare, and many a times, these are metastatic lesions with known or unknown primary location, most commonly arising from the stomach, duodenum, small intestine and rectum. NETs arising from the duodenum are more commonly seen in the first part of the duodenum followed by the second part. The incidence is increasing because of easy accessibility to endoscopies and cross-sectional imaging. In NETs, lymph node (LN) metastasis occurs commonly when the tumour size is more than 2 cm. In contrast, LN metastasis occurs even with subcentimetric lesions, especially the ampullary variant of NETs. A patient presented to us with mild abdominal pain and found to have retroduodenal mass. On evaluation found to be a metastatic LN deposit of NET with the primary arising from the first part and supra-ampullary part of duodenum.

Caecal desmoid tumour: a rare tumour at uncommon location and review of literature.

A 49-year-old woman presented to surgery outpatient clinic with the awareness of a right lower abdomen asymptomatic lump for one week. Contrast-enhanced CT of the abdomen demonstrated a 10×11×15 cm heterogeneous lesion anterior to the ileocecal junction with the possibility of leiomyosarcoma. The patient was prepared for laparotomy and intraoperative there was a large tumour arising from the medial wall of cecum. Right haemicolectomy was performed, and histopathology came as a desmoid tumour of the cecum. The patient had an uneventful postoperative course and is well on 1-year follow-up.

Quality of life assessment after parathyroidectomy in symptomatic primary hyperparathyroidism using the SF-36 questionnaire.

OBJECTIVES: Primary hyperparathyroidism (PHPT) is a systemic disease which, along with bone and stone disease, also causes several subjective symptoms which impairs the quality of life (QoL). However, NIH guidelines do not include non-specific physical and neuropsychological symptoms as an indication of parathyroidectomy. SF-36 is one of the most commonly used tools for assessing QoL; it measures both physical health (PH) and mental health (MH). MATERIAL AND METHODS: This is a prospective observational study including 50 patients of symptomatic PHPT. Patients were categorized into normocalcemia (8.5-10.4 mg/dL), mild hypercalcemia (10.5-11.9 mg/dL), moderate hypercalcemia (12-13.9 mg/dL), and severe hypercalcemia (>14 mg/dL). QoL was assessed by using SF36 survey both pre-operative and three months after parathyroidectomy. RESULTS: There was an overall improvement in QoL of individual groups both in PH and MH components (p <0.001). The improvement was more substantial for bodily pain, role physical, vitality and mental health. Although QoL was affected in patients with mild hypercalcemia, it was more affected in patients with severe hypercalcemia. The improvement in MH scores was dependent on the level of pre-operative calcium; however, the improvement in PH scores was independent of pre-operative calcium (p= 0.698). CONCLUSION: This study showed improvement in all aspects of PH and MH of SF-36 after parathyroidectomy, even in normocalcemics. Despite the fact that current guidelines for the management of PHPT do not include QoL as an indication for parathyroidectomy, we propose that parathyroidectomy should be considered, if patient is fit for surgery.

Surgical Residents' Perspective on Online Education during COVID-19 Pandemic.

<b> Introduction: </b> The COVID-19 pandemic is an exceptional situation which has rigorously affected surgical education and training worldwide. This current situation has carved innovative ways like online teaching to counter the challenges of the pandemic faced by a surgical resident. However, online teaching is not complimentary to bedside teaching which is a traditional practice. Therefore, we designed this study to assess the residents' perceptive towards online learning as a mode of education which is extensively implemented during the COVID-19 pandemic at our centre. </br></br> <b> Methods:</b> This study was a cross-sectional survey. An online Google survey was circulated among junior residents in the department of General Surgery. This survey included residents' demographic profile, effect on working hours, their perception with online teaching, and effect on their surgical training during the COVID 19 pandemic. </br></br> <b>Results:</b> A total of 95 junior residents participated in this study. Surgical training and teaching was rigorously affected according to most of them and they also believe they have lost crucial training time in their tenure as a surgical resident. A majority found the communication with the faculty during online teaching adequate; however, the main drawback of online classes was the lack of clinical exposure and practical experience. Only 4.2% preferred 100% online teaching in future. </br></br> <b> Conclusion:</b> COVID-19 pandemic has affected surgical training much more as compared to other medical fields. However, we believe online education is still a potential instrument during the COVID-19 pandemic. Online learning platforms can be used in future as a supplement to time-honoured classroom teaching and didactic lectures.

Impact of curative parathyroidectomy on left ventricular functions assessed with 2D ECHO and MUGA study.

Objectives: Primary hyperparathyroidism (PHPT) is associated with increased cardiovascular morbidity and mortality with inconsistent results on the reversibility of cardiovascular changes after parathyroidectomy (PTx). The present study was undertaken to evaluate both structural and functional cardiac changes and their reversal after PTx in patients with PHPT. Material and Methods: Thirty patients of symptomatic PHPT without cardiovascular risk factors were evaluated prospectively by means of 2D echocar- diography (ECHO) and Multigated Acquisition (MUGA) study before surgery and six months after curative parahyroidectomy. Results: Nine of 30 patients had hypertension which improved in two after PTx (p 0.20). Two patients had left ventricle hypertrophy on 2D ECHO pre- operatively which improved after PTx (p <0.001). Left ventricular ejection fraction (LVEF) did not show significant change before and after PTx on 2D ECHO. Nine out of 30 patients had hypertension which improved in two after PTx (p 0.20). Two patients with left ventricle hypertrophy on 2D ECHO preoperatively improved after PTx (p <0.001). Left ventricular ejection fraction (EF) did not depict significant change before and after PTx on 2D ECHO. Whereas, four out of six patients with preoperative EF <50% representing systolic dysfunction on MUGA study showed improvement after PTx. On 2D ECHO, eight patients depicted diastolic dysfunction which improved in six patients after curative surgery (p= 0.07). However, on MUGA study, 13 pa- tients presented with tTPF >180 ms indicating diastolic dysfunction, of which ten showed improvement after PTx (p= 0.007). Conclusion: The present study analyzed preoperative and postoperative cardiac function using both 2D ECHO and MUGA study. MUGA study provided a more objective assessment of the cardiac function by determining left ventricular ejection fraction and diastolic dysfunction.
