Jejunal Angiodysplasia as an Unusual Cause of Hemorrhage After Hepaticojejunostomy.

Ectopic variceal bleeding is a rare cause of postoperative hemorrhage following hepaticojejunostomy and should be differentiated from other causes such as pseudoaneurysms or ulcers. Uncommon complications post-hepaticojejunostomy demand scrupulous attention, and this case report reveals a seldom-documented scenario of jejunal angiodysplasia as an elusive cause of postoperative bleeding. Through a comprehensive examination of the patient's clinical trajectory, diagnostic challenges, and subsequent management, this report contributes to the expanding knowledge base on atypical vascular complications in surgical settings.

Innovative Approaches to Address the Technical Challenge of Hernial Sac Distension Due to Pneumoperitoneum in the Synchronous Management of Complex Hernias in Individuals With Morbid Obesity.

Although repairing ventral hernias in individuals who have undergone bariatric surgery is a common practice, persistent technical intricacies and controversies surround their management. Concurrently, addressing ventral hernias in morbidly obese patients undergoing bariatric surgery presents a significant surgical challenge, amplified by the larger intraperitoneal cavities and the presence of large hernial sacs. This technical report introduces two innovative techniques to alleviate the challenge of hernia sac distension due to pneumoperitoneum associated with simultaneous bariatric surgery and ventral hernia repair using laparoscopic technique. The methods are designed to address the complexities of the procedures, making their simultaneous execution feasible and safe. The goal is to eliminate the need for two separate interventions while ensuring the outcomes of each procedure remain uncompromised. The larger intraperitoneal cavities and the presence of large hernial sacs are managed successfully, demonstrating the feasibility and safety of the introduced methods. Importantly, the simultaneous execution of both procedures does not compromise the outcomes of either intervention. Concurrently managing ventral hernias in morbidly obese patients undergoing bariatric surgery requires innovative solutions to overcome technical challenges. The introduction of these two novel techniques proves to be a valuable approach, making simultaneous execution feasible and safe. Eliminating the need for two separate interventions streamlines the surgical process without compromising the outcomes of either bariatric surgery or ventral hernia repair.

Solitary Plasmacytoma of the Breast: A Rare Entity.

Solitary plasmacytoma of the breast is an extremely rare neoplastic entity characterized by the localized proliferation of neoplastic plasma cells within the breast tissue that requires careful consideration due to its clinical and radiological resemblance to more common breast malignancies. While plasmacytomas are typically associated with multiple myeloma (MM), primary involvement of the breast as a solitary lesion is exceptionally rare. In this report, we present a case of solitary plasmacytoma of the breast in a 55-year-old female patient who presented with a palpable breast mass and no signs of systemic multiple myeloma. Our objective is to discuss the clinical presentation, radiological features, and histopathological findings and highlight the importance of comprehensive diagnostic workup and management planning for solitary plasmacytomas of the breast.

Primary Right Adrenal Teratoma in a Postmenopausal Female: a Case Report and Review of Literature.

Non-seminomatous germ cell tumors with structural components from all three cellular lineages are called teratomas. We report a rare case of a primary right adrenal teratoma in a postmenopausal female, presenting with abdominal pain. Ultrasound revealed a complex cystic shadow in the perihepatic region superior to the upper pole of the right kidney, which was suggestive of a complex supra-renal space-sequence-occupying lesion. Computerized tomography revealed a large-sized mature single multilobulated complex cystic lesion in the right hypochondrial lumbar region arising from the right adrenal gland. A right-sided transperitoneal adrenalectomy was performed. The resected mass (18 × 13 × 10 cm) was well encapsulated. Cut surfaces showed cystic mass filled with necrotic gray-white pultaceous material, along with a solid white gelatinous area. Microscopic sections showed a tumor which displayed differentiation along various tissue lineages. After immunohistochemical examinations, the tumor was confirmed to be a mature cystic teratoma. Mature teratomas show a good prognosis, and surgical resection and follow-up remain the standard approach.

A Prospective Observational Study on the Outcome Assessment of Conservative Management Versus Intercostal Drainage (ICD) in Blunt Chest Injury Patients With ≤3 Rib Fractures in a North Indian Tertiary Care Center.

Introduction Trauma is the third most common cause of death in all age groups. One out of four trauma patients die due to thoracic injury or its complications. Seventy percent of thoracic traumas are due to blunt injury. This indicates the importance of chest trauma among all traumas. Quick and precise assessment bears paramount importance in deciding life-saving and definitive management. Often, the initial management in blunt injury patients is based on subjective assessment by the attending clinician. A scoring system that provides early identification of the patients at the greatest risk for respiratory failure and more likely to require mechanical ventilation and require prolonged care, as well as those with a higher mortality risk, may allow the early institution of intervention to improve outcomes. Thoracic Trauma Severity Score (TTSS) poses to be a precise tool in directing the management modality to be employed. Methodology This was an observational study including 112 patients of age >12 years, with blunt chest injury, sustaining ≤3 rib fractures, and with a stable chest wall. The patients with penetrating injury, those with blunt chest injury having flail segment, patients in the pediatric age group (<12 years), or polytrauma patients were excluded from our study. Of the 112 patients, 56 had been managed by intercostal drainage (ICD), and the rest (56) had been managed conservatively. Result Road traffic accidents (RTA) were the most common mode of injury in both groups. The percentage of the patients with one, two, and three rib fractures was 57.14%, 32.14%, and 10.71%, respectively, in the ICD group and 85.71%, 7.14%, and 7.14%, respectively, in the conservative management group (p = 0.124). The mean TTSS score was significantly more in the ICD group as compared to the conservative management group in the single rib fracture patients (p = 0.001*), as well as all patients of any number of rib fractures (p < 0.01*) (significance was defined as a value of p less than 0.05 {indicated by an asterisk}). The mean hospital stay was significantly lower in the conservative group as compared to the ICD group (p < 0.01*). The mean SF-36 (outcome) was significantly more in the conservative management group as compared to the ICD group (p = 0.020*). The mean cost of treatment was significantly more in the ICD group as compared to the conservative management group (p < 0.001*). Conclusion In our study, a TTSS (as measured by the primary care surgeon) of >7, across any number of rib fractures, was preferably predictive of management by ICD, while a <7 value was favorable for conservative management. TTSS can be used as an important tool to predict the management modality in blunt chest injury patients with ≤3 rib fractures.

Initial Retrocolic Endoscopic Tunnel Approach As an Ergonomic and Oncologically Apt Laparoscopic Technique for Resection of Malignant Right Colonic Lesions: An Experience from a University Hospital.

Introduction: Radical minimal access cancer surgery has demonstrated similar outcomes as open surgery of late, but with less morbidity, improving the quality of life especially in patients with colorectal cancer. Initial retrocolic endoscopic tunnel approach (IRETA) has been described in the literature by Palanivelu et al. as a laparoscopic technique for radical resection of malignant right colonic lesions (MRCL) following the modified concept of medial to lateral dissection. In this work, the authors present their experience of this ergonomic surgical technique. Materials and Methods: To begin with, retrocolic dissection was carried out to free and dissect the ascending colon up to hepatic flexure with the reflection of the peritoneum over the right colon along the white line of Toldt with abdominal wall kept intact initially to sustain intracorporeal specimen steadiness. Subsequently, the specimen is lifted medially in a distinct lymphovascular sheath, leading to high ligation of ileocolic, right colic, and the right branch of the middle colic vein with a consequent definite en bloc thorough removal of the lesion. The specimen was delivered through a transumbilical incision. Results: Ten patients (age 45.4 ± 5.6 years) underwent resection by the IRETA technique with a mean operating time of 185 ± 30 minutes and blood loss of 90 ± 20 mL. Mean hospital stay was 6 days. R0 surgical resection was achieved in all patients with proper marginal clearance. Ninety percent had adequate lymph nodal resection. One patient had an intraoperative complication and n = 3 patients developed postoperative ileus. Adjuvant chemotherapy was given and there is no recurrence on 28 months of average follow-up. Conclusion: With the increasing use of laparoscopic surgery for the management of colorectal cancers, the IRETA technique appears to be an ergonomic and oncologically robust procedure for the removal of MRCL. The presented data set needs to be increased with at least 5 years of follow-up to establish long-term surgical outcomes.

A prospective randomised control trial to compare the perioperative outcomes and ergonomic challenges between triangular versus midline port placement in total extra-peritoneal repair of uncomplicated unilateral inguinal hernia.

BACKGROUND: Routine TEP technique requires three skin incisions for placement of three trocars in the midline. Otherwise, this can be done by three-port triangular technique or two-hand technique. This study reports a randomised trial of perioperative outcomes and ergonomics characteristics of this procedure using two different techniques of port insertion. METHODS: N = 28 patients were randomised into two groups for triangular three-port (TTEP) versus midline three-port TEP (MTEP) hernioplasty after informed written consent in Department of Surgery, King George's Medical University UP between September 2016 and September 2017 after institutional ethical approval. Patient-related outcomes in terms of quality of life (QOL) and ergonomic evaluation of the technique were compared in double-blinded fashion. RESULTS: Postoperative pain score at 24 h post surgery (5.1 ± 0.6; 95% CI 4.9-5.3 vs. 4.8 ± 0.4; 95% CI 4.6-4.9) differed, while hospital stay, time to return to routine work, tolerance to oral feeds and intraoperative complications occurrence (OR 2.1; 95% CI 0.2-24.3) were comparable in both groups. Time to return to office work (5.5 ± 0.5; 95% CI 5.4-5.7 vs. 4.0 ± 0.8; 95% CI 3.7-4.3) and immediate postoperative sensation of mesh and pain score were significantly higher in MTEP compared to TTEP. Ergonomic parameters including visualization of landmark score, spreading of mesh score and total surgeon satisfaction score (TTEP 8.4 ± 0.7; 95% CI 8.1-8.6 vs. MTEP 7.0 ± 0.8; 95% CI 6.7-7.3), mental effort quotient (SMEQ score: TTEP 50.6 ± 12.7; 95% CI 45.9-55.3 vs. MTEP 70.8 ± 12.6: 95% CI 66.1-75.4) and physical effort quotient (LEDQ scores in wrist, hand, arm and shoulders) were also superior in triangular technique of port placement. CONCLUSION: Triangular three-port TEP hernioplasty is ergonomically feasible and enables a surgeon to perform surgery safely using basic principles of laparoscopy.

Malignancy prediction among tissues from Oral SCC patients including neck invasions: a 1H HRMAS NMR based metabolomic study.

INTRODUCTION: Oral cancer is a sixth commonly occurring cancer globally. The use of tobacco and alcohol consumption are being considered as the major risk factors for oral cancer. The metabolic profiling of tissue specimens for developing carcinogenic perturbations will allow better prognosis. OBJECTIVES: To profile and generate precise 1H HRMAS NMR spectral and quantitative statistical models of oral squamous cell carcinoma (OSCC) in tissue specimens including tumor, bed, margin and facial muscles. To apply the model in blinded prediction of malignancy among oral and neck tissues in an unknown set of patients suffering from OSCC along with neck invasion. METHODS: Statistical models of 1H HRMAS NMR spectral data on 180 tissues comprising tumor, margin and bed from 43 OSCC patients were performed. The combined metabolites, lipids spectral intensity and concentration-based malignancy prediction models were proposed. Further, 64 tissue specimens from twelve patients, including neck invasions, were tested for malignancy in a blinded manner. RESULTS: Forty-eight metabolites including lipids have been quantified in tumor and adjacent tissues. All metabolites other than lipids were found to be upregulated in malignant tissues except for ambiguous glucose. All of three prediction models have successfully identified malignancy status among blinded set of 64 tissues from 12 OSCC patients with an accuracy of above 90%. CONCLUSION: The efficiency of the models in malignancy prediction based on tumor induced metabolic perturbations supported by histopathological validation may revolutionize the OSCC assessment. Further, the results may enable machine learning to trace tumor induced altered metabolic pathways for better pattern recognition. Thus, it complements the newly developed REIMS-MS iKnife real time precession during surgery.

Alteration in lipid composition differentiates breast cancer tissues: a 1H HRMAS NMR metabolomic study.

INTRODUCTION: Breast cancer is the most frequent diagnosed cancer among women with a mortality rate of 15% of all cancer related deaths in women. Breast cancer is heterogeneous in nature and produces plethora of metabolites allowing its early detection using molecular diagnostic techniques like magnetic resonance spectroscopy. OBJECTIVES: To evaluate the variation in metabolic profile of breast cancer focusing on lipids as triglycerides (TG) and free fatty acids (FFA) that may alter in malignant breast tissues and lymph nodes from adjacent benign breast tissues by HRMAS 1H NMR spectroscopy. METHODS: The 1H NMR spectra recorded on 173 tissue specimens comprising of breast tumor tissues, adjacent tissues, few lymph nodes and overlying skin tissues obtained from 67 patients suffering from breast cancer. Multivariate statistical analysis was employed to identify metabolites acting as major confounders for differentiation of malignancy. RESULT: Reduction in lipid content were observed in malignant breast tissues along with a higher fraction of FFA. Four small molecule metabolites e.g., choline containing compounds (Chocc), taurine, glycine, and glutamate were also identified as major confounders. The test set for prediction provided sensitivity and specificity of more than 90% excluding the lymph nodes and skin tissues. CONCLUSION: Fatty acids composition in breast cancer using in vivo magnetic resonance spectroscopy (MRS) is gaining its importance in clinical settings (Coum et al. in Magn Reson Mater Phys Biol Med 29:1-4, 2016). The present study may help in future for precise evaluation of lipid classification including small molecules as a source of early diagnosis of invasive ductal carcinoma by employing in vivo magnetic resonance spectroscopic methods.

Expression of vitamin D receptor and vitamin D status in patients with oral neoplasms and effect of vitamin D supplementation on quality of life in advanced cancer treatment.

AIM OF THE STUDY: Vitamin D receptor (VDR) expression and serum vitamin D scores in oral premalignant lesions and oral cancer have not been widely analyzed. The role of vitamin D supplementation in advanced oral cancer for improving quality of life (QOL) is also a matter of research. MATERIAL AND METHODS: Vitamin D receptor expression and vitamin D scores were analyzed in normal oral mucosa (n = 95), leukoplakia (n = 23) and oral cancer (n = 87). 45 patients with advanced oral cancer subjected to chemoradiation were evaluated for the effect of vitamin D supplementation on most observable QOL parameters such as oral mucositis, swallowing performance and overall QOL. RESULTS: Vitamin D receptor expression was increased in oral neoplastic lesions. Vitamin D scores were significantly lower in cases compared to healthy controls (p = 0.002). Vitamin D supplementation significantly reduced the therapy-related toxicities in advanced cancer, thus reducing morbidity and improving QOL. CONCLUSIONS: Vitamin D receptor expression is increased in premalignant lesions and oral cancer. Vitamin D insufficiency and deficiency are prevalent in patients with oral neoplastic lesions. Vitamin D supplementation has a role in reducing treatment-related toxicities, especially in advanced cancer.

Androgen Receptor Expression in an Indian Breast Cancer Cohort with Relation to Molecular Subtypes and Response to Neoadjuvant Chemotherapy - a Prospective Clinical Study.

BACKGROUND: Breast cancer (BC) is associated with advanced presentation in developing countries like India due to various socio-economic factors. The presence of BC molecular subtypes such as the triple-negative (TN) subtype adds to this menace. Androgen receptor (AR) is emerging as a new biological marker. The aim of this study was to examine the prevalence of AR with relation to different BC subtypes, and its role in predicting response to neoadjuvant chemotherapy. METHODS: 116 cases of invasive BC (infiltrating ductal carcinoma, not otherwise specified) were evaluated. AR expression was correlated with clinicopathological factors, established prognostic markers, BC subtypes and it ability for predicting response to neoadjuvant chemotherapy. RESULTS: AR was expressed in 56% of the cases. AR expression was significantly associated with early stage (p < 0.03), low axillary burden (p < 0.04), estrogen receptor (p = 0.002), progesterone receptor (p = 0.001) expression and luminal A molecular subtype. No significant association was observed with age, tumor size and HER2/neu status. One-third of TNBC cases expressed AR. Higher AR expression corelated to good clinical response to neoadjuvant chemotherapy. CONCLUSION: AR can be utilized as a predictor of response to neoadjuvant chemotherapy especially in developing countries such as India where the load of advanced disease is high.

A Prospective Randomized Controlled Trial Comparing Quality of Life Following Endoscopic Totally Extraperitoneal (TEP) Versus Open Stoppa Inguinal Hernioplasty.

In inguinal hernia surgery, quality of life (QOL) has emerged as a striking issue. Evidence suggests better QOL of patients operated with laparoscopic procedure as compared with open anterior hernia repairs. However data are scarce with relation to open posterior repair in terms of QOL issues. A prospective randomized single-blind study from November 2014 to October 2015 including all patients who underwent elective primary endoscopic [totally extraperitoneal (TEP)] or open Stoppa inguinal hernia repair was undertaken. Mean operating time, intraoperative and postoperative complications, and QOL using short form-36 and Carolinas equation of QOL were analyzed. Physical functioning, mental health, bodily pain, and general health showed advantages of TEP over Stoppa repair in first month of postoperative period. Postoperative prediction of hernia discomfort after 1 year was found to be significantly more in Stoppa repair. Complications were slightly higher with open repair. To conclude TEP is associated with significant increased operative time, better QOL in early postoperative period, and less predicted discomfort after 1 year of surgery.

p16 and p53 in HPV-positive versus HPV-negative oral squamous cell carcinoma: do pathways differ?

BACKGROUND: p16 overexpression and wild-type p53 expression are associated with human papilloma virus (HPV) in cervical and oropharyngeal cancer. Role of HPV-related carcinogenesis in the etiology of oral squamous cell carcinoma (OSCC) is still vague in Indian population. We aimed to explore the expression pattern of p16 and p53 in HPV-positive and HPV-negative OSCC to elicit differences, if any. Further their effect on survival of patients was studied. METHODS: Thirty-one consecutive HPV-positive as well as 31 age and sex-matched HPV-negative OSCC cases from a case series of 369 histologically diagnosed cases of OSCC were included in this study. HPV was detected by two methods, viz. real-time PCR and conventional PCR in biopsy samples. p16 and p53 protein expression was assessed by immunohistochemistry, and p16 mRNA expression was quantified with real-time PCR using SYBR Green assay. RESULTS: p16 was expressed in six (19.4%) HPV-positive and in four (12.9%) HPV-negative cases. Overall mutant-type p53 expression in 62 OSCC cases was 54.8%. Out of ten p16-positive cases, eight expressed mutant-type p53 and only two cases expressed wild-type p53. Risk factors including oral tobacco consumption and alcohol were present in all these ten p16-positive cases. Survival of patients was not affected by HPV, p16 and p53 status. CONCLUSION: Presence of mutant-type p53 and exposure to tobacco-related risk factors in both HPV-positive and negative cases suggest existence of p53-related carcinogenesis in HPV-positive cases in Indian population.

Taurine - a possible fingerprint biomarker in non-muscle invasive bladder cancer: A pilot study by 1H NMR spectroscopy.

Urinary bladder cancer is a major epidemiological problem that continues to grow each year. It opens avenues for investigative research for the identification of new disease markers and diagnostic techniques. In this pilot study, utility of non-invasive (1)H NMR spectroscopy has been evaluated for probing the metabolic perturbations occurring in non-muscle invasive urinary bladder cancer. (1)H NMR spectra of urine of bladder cancer patients and controls (healthy and urinary tract infection/bladder stone) (n = 103) were acquired at 400MHz. The non-overlapping resonances of citrate, dimethylamine, phenylalanine, taurine and hippurate were first identified and then quantitated by (1)H NMR spectra, with respect to an external reference sodium-3-trimethylsilylpropionate (TSP). The concentrations of these metabolites were then statistically analyzed. The cancer patients showed significant (p < 0.05) variations in concentration of hippurate and citrate as compared with healthy controls and benign controls. The significant elevation in concentration of taurine was observed in urine of bladder cancer patients, which was below the sensitivity limit of 400MHz in control cases. However, stages Ta, T1 and carcinoma in situ (CIS) cannot be differentiated on the basis of altered metabolite indices but their composition may reflect the biochemical alterations in metabolism of cancer cells.

Proton HR-MAS NMR spectroscopic characterization of metabolites in various human organ tissues: pancreas, brain and liver from trauma cases.

High-Resolution Magic Angle Spinning (HR-MAS) NMR has been employed to characterize various metabolites of human pancreas, liver and brain tissues from trauma cases. The potential usefulness of NMR in identifying the metabolites in human tissues has been explored using a combination of one- and two-dimensional experiments. The complete resonance assignments of pancreas tissue have been carried out for the first time. Two new metabolites, alpha-hydroxyisovalarate and alpha-hydroxybutarate were identified in all the tissue specimens. The metabolites information of these human tissues can further be utilized in correlating several diseases associated with pathological manifestations as well in distinguishing traumatic tissues along with control tissues of pancreas, liver and brain.
