Unusual Triggers of Acute Intestinal Obstruction in Surgical Emergencies: A Series of Five Cases.

Intestinal obstruction is a common surgical emergency that can be caused by mechanical causes or by different pathological processes. The most common cause of small bowel intestinal obstruction is post-operative adhesion, and the most common cause of large bowel obstruction is malignancy. These are classified into dynamic and adynamic types. The patient was selected based on the presentation management plan. Some cases require immediate operative intervention; however, some cases, as mentioned in this case series, require further investigation and a different approach. In this study, we report the rare causes of intestinal obstruction presented to Safdarjung Hospital, Department of General Surgery, New Delhi: one case of foreign body impaction, one case of spontaneous migration of feeding jejunostomy, one case of extrauterine IUCD causing intestinal obstruction, one case of mesentery band causing obstruction, and one case of abdominopelvic mass causing small bowel obstruction. These cases presented to the surgical emergency department with challenges in their diagnosis, intraoperative findings, and their outcomes.

Compound Volvulus: A Rare Case of Intestinal Obstruction.

Compound volvulus or ileosigmoid knotting is an uncommon surgical emergency that causes intestinal obstruction. The sigmoid and ileum are mostly involved in this closed-loop intestinal obstruction. It is regarded as a rather uncommon cause of intestinal obstruction. It's important to distinguish between an ileosigmoid knot and a simple sigmoid volvulus since the management of the two is different. CT and MRI are more helpful in the diagnosis than abdominal X-ray findings, which are not pathognomonic. After resuscitation, a patient with ileosigmoid knotting typically needs an emergency laparotomy. Different resectional and non-resectional surgical procedures may be employed depending on the viability of the ileum and sigmoid colon.

Evaluation of Negative Pressure Wound Therapy in the Management of Fournier's Gangrene.

Introduction Necrotizing soft tissue infections (NSTIs), including Fournier's gangrene (FG), are severe polymicrobial bacterial infections characterized by rapidly spreading inflammation and tissue necrosis. This study aims to compare the clinical outcomes of vacuum-assisted closure (VAC) dressing and conventional dressing in patients with FG. Materials and methods A prospective study was conducted from December 2020 to May 2022, including patients with clinical features suggestive of FG. Patients were divided into two groups: conventional dressing and VAC dressing. Relevant clinical data, including age, duration of hospital stay, wound status, Fournier's gangrene severity index (FGSI) scores, sepsis markers (C-reactive protein (CRP), neutrophil-to-lymphocyte ratio, and procalcitonin), and pain assessment, were recorded and compared between the two groups. Results A total of 84 patients were included in the study, with 42 patients in each group. The mean age was 57.48 ± 15.74 years in the conventional dressing group and 50.83 ± 13.95 years in the VAC dressing group. VAC dressing was associated with a significantly shorter duration of hospital stay (8.14 ± 3.13 days) compared to conventional dressing (11.36 ± 4.75 days). The average time taken for wound closure was significantly reduced in the VAC dressing group (63 ± 14.81 days) compared to the conventional dressing group (112.56 ± 13.82 days). FGSI scores showed significant improvement after debridement in both groups, with lower scores in the VAC dressing group at discharge. Sepsis markers such as CRP and serum procalcitonin exhibited a significant decrease after VAC application. Discussion The study demonstrates that VAC therapy is associated with better clinical outcomes in FG, including reduced duration of hospital stay, faster wound closure, improved FGSI scores, decreased sepsis markers, and reduced pain. These findings align with previous studies highlighting the advantages of VAC therapy over conventional dressing methods. Conclusion VAC therapy provides significant benefits in the management of FG, leading to improved clinical outcomes and patient quality of life. It offers advantages such as shorter hospital stays, faster wound closure, and reduced sepsis markers. The application of VAC dressing should be considered a valuable treatment modality for FG.

Survival Secrets: Unmasking the Factors Predicting Failure of Non-operative Management (NOM) in Splenic Injuries.

BACKGROUND: Splenic injuries are common solid organ injuries resulting from blunt abdominal trauma in road traffic accidents. Very often, splenic injuries can be life-threatening. Earlier, splenic injuries were often dealt with surgical intervention, such as splenectomy. With the recognition of the immunological function of the spleen and possible complications of splenectomy surgery, such as overwhelming post-splenectomy infections (OPSI), there has been a recent trend for non-operative management (NOM). OBJECTIVE: To study the variables predicting failure of NOM in blunt abdominal trauma patients with splenic injury. METHODS: This is a retrospective study that includes 235 patients who presented to the Safdarjung Hospital emergency room (New Delhi, India) with blunt trauma abdomen and splenic injuries with or without associated injuries between January 2019 and December 2021. The data was entered in a Microsoft Excel spreadsheet (Microsoft Corp., Redmond, WA, USA). Categorical variables were expressed as frequencies and percentages. Pearson's chi-square test of association was used to determine if there is a relationship between two variables. A p-value of <0.05 was considered statistically significant. RESULTS: Out of 235 patients with blunt abdominal trauma and splenic injuries, 82 were hemodynamically unstable despite resuscitation and were taken up for emergency laparotomy. The remaining 153 patients, who were either hemodynamically stable or stabilized after adequate resuscitation, were managed on the lines of NOM. The number of patients with splenic injury in AAST grades 1, 2, 3, 4, and 5 was 36, 50, 40, 24, and three, respectively. Out of 153 patients, 130 (85%) were successfully managed by NOM, while eight (5%) had to discontinue NOM as they required surgical intervention. The failure of NOM (fNOM) is seen mostly with grade 5 injuries (2/2, 100%, p<0.01), followed by grade 4 (4/20, 20%) and grade 3 (2/37, 5.7%). The mean age in fNOM was 58.3 years, as compared to 42.2 years in the success of NOM (sNOM). All eight patients had multiple concomitant injuries, with femur fracture being the most common association in up to six patients (p<0.01), followed by liver injury in four patients. There were 15 mortalities, irrespective of AAST severity grade. All of these patients had associated concomitant injuries, with intracranial bleeding (n = 10, 32%, p<0.01) being the most common association, followed by femur fracture (n = 6, 20%) and liver injury (n = 5, 16%). Also, the cause of death was unrelated to splenic trauma (p = 0.67), with pulmonary embolism (n = 6, 40%, p<0.01) being the most common cause, followed by brain stem herniation (n = 5, 34%). CONCLUSION: Non-operative management is a safe and efficient method for treating patients with splenic injuries who are hemodynamically stable or stabilized. The factors associated with fNOM include elderly age, a higher American Association for the Surgery of Trauma (AAST) grade of splenic injury, and associated concomitant injuries. Femur fracture was the most common concomitant injury present in cases where NOM failed, followed by liver injury. The presence of intracranial bleeds in these patients was a common association with mortality, irrespective of the grade of splenic injury.

Assessment of Response to Neoadjuvant Chemotherapy in Locally Advanced Breast Carcinoma Using Image-Guided Clip Placement.

Background The present study aims to evaluate the response of locally advanced breast carcinoma (LABC) to neoadjuvant chemotherapy (NACT) using image-guided clip placement based on Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria. Methods Thirty-four patients with LABC were included in the study. Consent for three-dimensional titanium clip placement (400/300/200 mm Liga clips) under local anesthesia with USG guidance was obtained. Serial sonographic/X-ray evaluations of tumor bed size were conducted before every cycle of NACT. All data were recorded in millimeters of concentric tumor regression/non-regression. Tumor regression in a concentric or Swiss cheese pattern and non-responders were evaluated. Assessment of the response to NACT was performed using RECIST criteria, dividing it into four categories. Tumor response was confirmed with computerized tomography (CT) conducted before and after the completion of NACT. Patients underwent surgical management, mostly modified radical mastectomy (MRM), as they had locally advanced breast carcinoma. Following MRM, the clips in the specimen guided the original site of the tumor for histopathological evaluation and response to chemotherapy. Results Tumor response was classified into four types: complete response (CR), partial response (PR), progressive disease (PD), and stable disease. RECIST 1.1 criteria were elaborated and defined. Data for all patients were entered into an Excel sheet (Microsoft Corporation, Redmond, Washington) to prepare a master chart, and the following observations were made and analyzed using SPSS software. The duration of chemotherapy for the study population ranged from 32 to 206 days, with a mean (±SD) of 111.82 (± 52.64) days and a median (IQR) of 81 (63, 158) days. The mean period between clip insertion and completion of NACT was 111.82 days. The baseline sum diameters and post-NACT diameters of the tumors were 70.50 (±13.60) mm before NACT and 17.75 (±17.20) mm after NACT. Hence, the mean size of the lump was statistically significantly lower after NACT, with a mean difference of 52.75 (p<0.05). The mean rate of reduction in tumor diameter was found to be 74.32% (±23.44%) based on RECIST 1.1 criteria. Pathological response was observed in all patients except for 8.8% of the patients. Clinical complete response was seen in 35.29% of patients, and partial response was observed in 52.92% of the patients based on RECIST 1.1 criteria. The study thus demonstrates the effectiveness of NACT in LABC, with a mean reduction in tumor diameter of 74.32%, assessed with the help of RECIST 1.1 criteria. Conclusion NACT for patients with LABC has shown a significant reduction in tumor size. NACT should be the initial mode of management for patients with LABC. RECIST 1.1 criteria are effective and can be used to assess tumor response to NACT. This has aided in the stratification of the response of NACT for further management through systemic therapy (adjuvant chemotherapy) after the surgical excision of the tumor.

Rare Hernias as Surgical Emergencies: A Case Series of Five Cases.

Hernia is one of the most common clinically diagnosed cases seen in day-to-day practice. But some of them might pose a challenge in diagnosing the condition and, thus, their further management. Some types of hernias are rare and mimic the common presentation of the acute abdomen, thus requiring extra caution to keep hernias as a differential diagnosis in the acute abdomen. In this series, we report five cases of rare hernias presented to a tertiary care center in northern India over the course of one year. Two cases of paraduodenal hernias (PHs), a right and left, respectively, a male femoral hernia, an Amayand hernia, and an obturator hernia presented as acute abdomen in the emergency department, with challenges in their diagnosis, intraoperative findings, and their outcomes. Computed tomography is a useful diagnostic tool for arriving at the diagnosis pre-operatively in these situations.

Revolutionizing Breast Healthcare: Harnessing the Role of Artificial Intelligence.

Breast cancer has the highest incidence and second-highest mortality rate among all cancers. The management of breast cancer is being revolutionized by artificial intelligence (AI), which is improving early detection, pathological diagnosis, risk assessment, individualized treatment recommendations, and treatment response prediction. Nuclear medicine has used artificial intelligence (AI) for over 50 years, but more recent advances in machine learning (ML) and deep learning (DL) have given AI in nuclear medicine additional capabilities. AI accurately analyzes breast imaging scans for early detection, minimizing false negatives while offering radiologists reliable, swift image processing assistance. It smoothly fits into radiology workflows, which may result in early treatments and reduced expenditures. In pathological diagnosis, artificial intelligence improves the quality of diagnostic data by ensuring accurate diagnoses, lowering inter-observer variability, speeding up the review process, and identifying errors or poor slides. By taking into consideration nutritional, genetic, and environmental factors, providing individualized risk assessments, and recommending more regular tests for higher-risk patients, AI aids with the risk assessment of breast cancer. The integration of clinical and genetic data into individualized treatment recommendations by AI facilitates collaborative decision-making and resource allocation optimization while also enabling patient progress monitoring, drug interaction consideration, and alignment with clinical guidelines. AI is used to analyze patient data, imaging, genomic data, and pathology reports in order to forecast how a treatment would respond. These models anticipate treatment outcomes, make sure that clinical recommendations are followed, and learn from historical data. The implementation of AI in medicine is hampered by issues with data quality, integration with healthcare IT systems, data protection, bias reduction, and ethical considerations, necessitating transparency and constant surveillance. Protecting patient privacy, resolving biases, maintaining transparency, identifying fault for mistakes, and ensuring fair access are just a few examples of ethical considerations. To preserve patient trust and address the effect on the healthcare workforce, ethical frameworks must be developed. The amazing potential of AI in the treatment of breast cancer calls for careful examination of its ethical and practical implications. We aim to review the comprehensive role of artificial intelligence in breast cancer management.

DOG1-Positive Extragastrointestinal Stromal Tumor Presenting As Large Abdomino-Pelvic Mass: A Case Report.

Gastrointestinal stromal tumors (GIST) are mesenchymal tumors commonly arising from the GI tract. Only a small number of GIST originating outside the GI tract have been reported in the literature. They are termed extraintestinal GIST (E-GIST), with histological features similar to GIST. These commonly arise from the omentum, mesentery, or abdominal wall. Microscopic examination shows spindle or epitheloid morphology with immunohistochemistry (IHC) positivity for the cluster of differentiation 117, 34 (CD117, CD34), or discovered on GIST-1 (DOG1). This case series describes the presentation of two cases of E-GIST as an abdominopelvic mass with DOG1 positivity and CD117 negativity on IHC. Patient in the first case presented with a giant abdominopelvic mass, clinically arising from the pelvis with a misdiagnosis of midline desmoid tumor. It was completely excised with a histological surprise of E-GIST with DOG1 positivity on IHC. The second case presented a swelling in the groin region, separate from the testis but arising from the anterior abdominal wall, with histological features of E-GIST with DOG1 positivity. The cases reported here show further evidence regarding the existence of a distinct subset of GISTs characterized by extraintestinal localization, with negative immunohistochemical expression of receptor tyrosine kinases (KIT) and positive DOG1 expression, which appears to be rare and makes DOG1 an emerging marker for GIST.
