Surgery for a symptomatic massive liver haemangioma.

Liver haemangiomas are the most common benign hepatic tumours, but secondary portal hypertension resulting from haemangiomas is exceedingly uncommon. We present a case of a man in his 50s who presented with a progressively enlarging mass in the right upper abdomen. CT of the liver revealed a large hypodense lesion involving the right lobe, with two smaller lesions in the left lobe. The portal vein was compressed by the tumour, causing portal hypertension. The patient underwent right hepatectomy. Postoperatively, the patient had an uneventful course, and a 3-month follow-up demonstrated resolution of the oesophageal varices, portal gastropathy, with hypertrophy of the left lobe. This case report highlights the successful surgical management of a rare massive hepatic haemangioma causing portal hypertension with surgical resection, emphasising the potential benefits of surgical intervention with minimal complications.

Memory Classifiers for Robust ECG Classification against Physiological Noise.

The development of sophisticated machine learning algorithms has made it possible to detect critical health conditions like cardiac arrhythmia, directly from electrocardiogram (ECG) recordings. Large-scale machine learning models, like deep neural networks, are well known to underperform when subjected to small perturbations which would not pose a challenge to physicians. This is a hurdle that needs to be removed to facilitate wide-scale adoption. We find this to be true even for models trained using data-augmentation schemes.In this paper, we show that using memory classifiers it is possible to attain a boost in robustness using expert-informed features. Memory classifiers combine standard deep neural network training with a domain knowledge-guided similarity metric to boost the robustness of classifiers. We evaluate the performance of the models against naturally occurring physiological perturbations, specifically electrode movement, muscle artifact, and baseline wander noise. Our approach demonstrates improved robustness across all evaluated noises for an average improvement in F1 score of 3.13% compared to models using data augmentation techniques.Clinical relevance- This approach improves the robustness of deep learning methods in safety-critical medical applications.

Successful management of a rare case of gallbladder neuroendocrine carcinoma with tumor thrombi.

A gallbladder neuroendocrine neoplasm (GB­NEN) is a bizarre heterogeneous neoplasm arising from neuroendocrine cells, which are present in minimal amounts on the GB mucosa either due to conversion of undifferentiated stem cells, chronic inflammation and resulting in pathological metaplasia or switching of GB adenocarcinoma to neuroendocrine one. Among all the GB malignancies, GB-NEN accounts for approximately 2.1%. A 41-year-old lady presented with right upper abdomen pain and distension for 2 weeks. Contrast CT showed heterogeneously enhancing wall thickening involving fundus-body of the GB with large exophytic component involving segments IV/V of liver, peripheral enhancement and central low attenuating necrotic areas. Middle hepatic and left branch of portal vein was filled with enhancing lesion, tumor thrombi. She underwent left trisectionectomy followed by adjuvant chemotherapy. Postoperative biopsy reported as poorly differentiated unifocal small cell GB-neuroendocrine carcinomas (GB-NEC). Resected margins were free of tumor with periportal lymph nodes negative for tumor. Follow-up PET-CT after six months of treatment completion shows no tumor recurrence or metastases. She has completed 12 months following the surgery and is asymptomatic. As the occurrence of GB-NEC is rare, there are little data regarding etiology, pathogenesis, treatment and prognosis of it. Even though metastasis is early and most frequent to lymph nodes, liver, lung and peritoneum, the presence of tumor thrombus in GB-NEC is rarely reported. Though most reports suggest very poor outcomes, radical surgery followed by adjuvant chemotherapy can yield good short-term results as seen in this case.

The Incidence and Severity of Patient-Reported Side Effects of Chemotherapy in Routine Clinical Care: A Prospective Observational Study.

INTRODUCTION: Understanding patients' self-reported chemotherapy side effects is significant because it affects patients' quality of life (QOL) and compliance with treatment. Our current knowledge of chemotherapy side effects comes from available literature, whose external validity is questionable. Moreover, there are very few studies available in the literature that focus on various cancers and their associated side effects. METHODS: A single-center, prospective observational study was conducted at a tertiary care center from July 2019 to July 2021. After deriving the sample size, we interviewed 76 consecutive study patients with gastric, periampullary, colorectal, and breast cancer for six months after chemotherapy initiation with a structured patient-reported outcome tool adapted in English and Tamil to record the side effects like diarrhea, vomiting, chest pain, constipation, dyspnea, fatigue, mucositis, and rash. The grading of symptoms was done according to the Common Terminology Criteria for Adverse Events version 5.0. The frequency and prevalence of side effects were calculated as the number of patients who reported the side effect of any grade at least once during the follow-up period. The incidence rate of side effects was calculated in terms of person-time. The association between each side effect and cancer type was calculated using the chi-square test and Fisher's exact test as appropriate. RESULTS: Of the 77 patients in the study, 51.9% were male, 63.6% were between 40 and 60 years of age, 45.5% had stage-3 disease, and 44.2% received neoadjuvant treatment. During the six-month follow-up period, 97.4% of patients experienced at least one side effect. Fatigue was the most common side effect (87%), followed by loss of appetite (71.4%) and diarrhea (49.4%). Approximately 66.7% of patients experienced six or more side effects. There was a statistically significant difference in the frequency of side effects between cancer types. However, age, socioeconomic status, BMI, comorbidity, chemo-intent, and stage of disease did not affect the frequency of side effects. CONCLUSIONS: This study highlights the need to integrate patient-reported side effects into routine clinical practice. Identifying these side effects, even if they are mild in intensity, and managing them in a timely manner may improve the patient's emotional state, QOL, and compliance with chemotherapy.

A Rare Case of Kissing Gastric Ulcers Secondary to Non-steroidal Anti-inflammatory Drug (NSAID) Intake.

Peptic ulcer disease is a heterogeneous disease caused by the imbalance between mucosal protective and aggressive factors. Such ulcers are common in the anterior wall of the duodenum and gastric antrum. Kissing ulcers, although commonly reported in the duodenum, are rarely seen in the stomach. We present a rare case of an 85-year-old lady who had an index presentation of sudden onset hematemesis following ibuprofen intake. Endoscopy revealed kissing gastric ulcers, which are extremely rare secondary to non-steroidal anti-inflammatory drugs. She had complete healing after treatment with proton pump inhibitors.

Outcomes of Patients With Acute Limb Ischemia in Patients With COVID-19: A Systemic Review and Meta-Analysis.

A systemic review and meta-analysis of perioperative outcomes of acute limb ischemia (ALI) in patients with and without coronavirus disease-2019 (COVID-19) to determine the outcomes of ALI and compare the outcomes in patients with and without COVID-19 infection. A literature search of the Medline, Science Direct and Cochrane Library was performed from inception to July 15, 2021. Studies involving ALI in patients with COVID-19 were searched through three electronic databases. The endpoints include limb salvage, re-thrombosis, and mortality, and these outcomes were compared between patients with and without COVID-19 infection and type of management. The primary outcome was early limb salvage (till the patient was discharged from the hospital). The other outcomes assessed were re-thrombosis and mortality. These outcomes were compared between patients with and without COVID-19 infection and the type of management. Pooled estimates were presented as odds ratios (ORs) using a random or fixed effect model based on the results of the chi-square test and calculation of I2. Comparing the ALI outcomes in patients with and without COVID-19 infection, there was no significant difference in limb salvage rate (OR=0.26, 95% CI:0.02-3.09), but there was a significantly higher re-thrombosis (OR=2.65, 95% CI:1.34-5.23) and mortality rate (OR=4.71, 95% CI:1.11-19.99) in patients with COVID-19 infection. On comparing outcomes based on management, intervention group, and anticoagulant alone group, no significant difference was noted concerning limb salvage (OR=1.40, 95% CI:0.27-7.13) and mortality rates (OR=0.2, 95% CI:0.04-1.07). This meta-analysis demonstrates a higher re-thrombosis and mortality in ALI patients with COVID-19 infection when compared to patients without COVID-19 but with similar limb salvage.

Outcomes of Emergency Abdominal Wall Hernia Repair: Experience Over a Decade.

Background Abdominal wall hernias are a common surgical entity encountered by the general surgeon. Approximately 10% of abdominal wall hernia patients require emergency surgery. However, these surgeries are associated with a high rate of postoperative morbidity and mortality. This study aimed to analyze the morbidity and mortality in patients undergoing emergency abdominal wall hernia repair and to determine the factors associated with surgical site infection (SSI) and recurrence in these patients attending a tertiary care hospital in south India. Methodology Our study was a single-centered, 10-year retrospective and a one-year prospective study conducted in a tertiary care center in India. All patients who underwent emergency abdominal wall hernia repair between April 2009 and May 2020 were included. Patients' demographic details, comorbidities, intraoperative findings, 30-day surgical outcomes including SSI, and recurrence were studied. Results Out of 383 patients in our study, 63.9% had an inguinal hernia, and 54% of the patients underwent tissue repair. SSI was the most common morbidity (21.9%). Postoperative sepsis was the only independent factor associated with perioperative mortality according to the logistic regression analysis (odds ratio = 22.73, p = 0.022). Conclusions Tissue repair for emergency hernia surgery has better outcomes than mesh repair in clean-contaminated cases.

Accuracy of Quick Sequential Organ Failure Assessment Score & Systemic Inflammatory Response Syndrome Criteria in Predicting Adverse Outcomes in Emergency Surgical Patients With Suspected Sepsis: A Prospective Observational Study.

PURPOSE: Due to the mixed population enrolled in different studies i.e., medical and surgical cases, conflicting data exists about the accuracy of quick sequential organ failure assessment (qSOFA) and systemic inflammatory response syndrome (SIRS) scores in predicting adverse outcomes in patients with suspected sepsis presenting to the surgical emergency. METHOD: A prospective observational study was done in the department of surgery of a tertiary teaching hospital, India from June 2018 to July 2019. Consecutive patients who visited the surgical emergency department with suspected sepsis were included. Patients were followed up until hospital discharge or death. RESULTS: Of the 410 patients screened, 287 were included in the analysis. The median age was 52 years (interquartile range, 41 to 61years) and 208 (72.8%) were men. Around 56.8% of patients had intra-abdominal pathology, and 43.2% had skin and soft -tissue infection. Sixty-nine (24%) patients died during their hospitalization, 98 (34.1%) patients had organ dysfunction, and 168 (58.5%) patients needed admission to the intensive care unit (ICU). A higher qSOFA score (≥2) was associated with organ dysfunction, ICU admission, and in-hospital mortality. The specificity, positive predictive value and diagnostic accuracy of qSOFA for organ dysfunction (85.7%, 67.8%, 76.3%), ICU admission (92.4%, 89.3%, 64.5%), and in-hospital mortality (81.6%, 52.4%, 77.4%) was higher than SIRS. The area under the receiver operating characteristic curve for qSOFA for these variables was also higher than for SIRS (0.826 vs. 0.524, 0.823 vs. 0.577, and 0.823 vs. 0.555, respectively). CONCLUSION:  qSOFA is a better model for predicting adverse outcomes and mortality, organ dysfunction, and ICU admission in surgical patients. However, SIRS indicates intervention requirements in a surgical patient better than qSOFA.

Role of Neoadjuvant Chemotherapy in Locally Advanced Carcinoma Stomach: An Analysis of the Short-Term Outcomes.

INTRODUCTION: Neoadjuvant chemotherapy (NACT) in carcinoma stomach was introduced in an effort to eliminate micro-metastasis and to improve resectablity before surgery which improves R0 resection rates. We aimed to study the short term outcomes of neoadjuvant chemotherapy on the Tumor Node Metastasis (TNM) stage and the operative outcomes including R0 resection rate in locally advanced gastric cancer. METHODS: We prospectively included patients with locally advanced adenocarcinoma stomach staged by contrast-enhanced computed tomography (CECT) in our study. Patients in Group I were started on neoadjuvant chemotherapy (epirubicin, oxaliplatin, and capecitabine). Surgery was done following response assessment CECT. Patients in Group II underwent upfront surgery. We assessed R0 resection rate, number of harvested and metastatic lymph nodes, lymph node ratio, duration of surgery, blood loss, hospital stay and complications between two groups. Response to NACT was assessed in Group I. RESULTS: Out of 47 patients who received NACT, two patients had complete response (4.2%), 13 had partial response (27.7%), 10 had stable disease (21.3%) and 22 patients had progressive disease (46.8%). We found no significant difference in the rate of R0 resection between the two groups (88.2% in NACT group vs 85.1% in surgery group, P=0.55). CONCLUSIONS: The rate of R0 resection does not significantly improve with neoadjuvant chemotherapy. In view of high progression rates, patient selection is required when NACT is planned in carcinoma stomach which are surgically resectable at presentation. We await survival analysis to further validate the role of NACT.

Solitary lower limb cutaneous metastasis in a case of esophageal adenocarcinoma: a rare presentation.

Esophageal cancer is the ninth most common cancer all over the world and is sixth in the list of cancer-related mortality. Here in this report, we present an elderly male with solitary subcutaneous metastasis to right thigh 2 years following esophagectomy for esophageal adenocarcinoma. Operative notes revealed inadequate margins on frozen section analysis during initial resection, which were subsequently revised. Postoperative histopathology showed ypT3N0M0 Grade 3 mucin-secreting adenocarcinoma. A wedge biopsy from the thigh growth revealed metastatic mucinous adenocarcinoma. Positron Emission Tomography (PET) was done, which showed a higher tracer uptake in the ulcero-proliferative lesion arising from the subcutaneous plane in the right thigh with no evidence of any other metastasis or recurrence at the primary site. As the reported incidence of distant unexpected metastases is growing, careful physical examination with a preoperative PET-CT is indispensable. Further knowledge on options on treatment of such isolated cutaneous metastasis needs to be studied by the scientific community.

Successful use of a mesocaval shunt to treat refractory ascites in a chronic pancreatitis induced portal vein thrombosis.

The state of intense peripancreatic inflammation in chronic pancreatitis can give rise to various vascular complications such as venous thrombosis and arterial pseudoaneurysms. Due to its intimate location with the pancreas, spleno-mesenteric-portal axis suffers the greatest blunt of thrombotic complications. Treatment modalities for such cases of chronic portal vein thrombosis have always been controversial and challenging. Medical management with anticoagulants is both risky and unsatisfactory due to presence of varices, hypersplenism, and persistence of the inflammatory pathology. Although endovascular techniques have been tried in various case reports, there are definite anatomical challenges in cases of long segment porto-mesenteric thrombosis with massive ascites. Surgical shunts have been historically described for cirrhotic and non-cirrhotic portal hypertensive patients. However, its use in patients with refractory ascites due to chronic pancreatitis induced portal vein thrombosis has not been reported in the medical literature. Here, we present a case of an extensive portal vein thrombosis with massive refractory ascites in a patient with alcohol-induced chronic pancreatitis successfully treated with a surgical mesocaval shunt using an interposition small diameter graft.

Co-infection of intestinal tuberculosis and mucormycosis in a patient with Down syndrome: a unique case report with literature review.

Mucormycosis represents several unusual opportunistic infection caused by saprophytic aseptate fungi. There is a recent rise in cases of mucormycosis due to an increase in diabetic and immunodeficient patients like patients on long-term steroids, immunomodulators due to organ transplantation, malignancies, mainly haematological malignancies, and autoimmunity. Anatomically, mucormycosis can be localised most commonly as rhino-orbito-cerebral followed by pulmonary, disseminated, cutaneous and gastrointestinal, rarest being small intestinal. Patients with Down syndrome are immunodeficient due to their impaired immune response. Disseminated tuberculosis is also common in immunodeficient patients. We report a rare case of small intestinal mucormycosis in a patient with Down syndrome with coexisting intestinal tuberculosis. Due to the invasiveness of mucormycosis, the patient succumbed to death despite providing aggressive surgical debridement and medical management.

A Rare Case of HIV-Associated Plasmablastic Lymphoma of Anal Canal.

Plasmablastic lymphoma, an acquired immunodeficiency syndrome defining malignancy, is a subtype of diffuse large B-cell lymphoma. It is classically described in the oral cavity, the extraoral presentation being rare. Owing to its rarity and aggressiveness, plasmablastic lymphoma poses a diagnostic and therapeutic challenge to the treating physician. A 40-year-old male, recently diagnosed with HIV infection, presented with bleeding per rectum and spurious diarrhea. Examination revealed proliferative growth in the anal canal. Biopsy of the lesion was diagnostic of plasmablastic lymphoma. Computed tomography and magnetic resonance imaging were done to stage the lesion and assess the local extent, respectively. A multidisciplinary board discussion was done, and the patient was instituted on antiretroviral therapy and chemoradiotherapy. Following six cycles of chemotherapy and 25 fractions of radiotherapy, he achieved complete remission.

Gastric Candidiasis Leading to Perforation: An Unusual Presentation.

Candidal infection of the gastrointestinal tract (GIT) is rare but has recently increased due to the increased number of immunocompromised patients, injudicious use of antibacterial agents, and prolonged use of antacid drugs in immunocompetent patients. The most frequent organ involved in GIT candidiasis is the esophagus, followed by the stomach, small intestine, and large intestine. The clinical spectrum of gastric candidiasis ranges from asymptomatic to gastric perforation and even shock. This case report presents a 58-year-old immunocompetent male patient diagnosed with Candida tropicalis-induced gastric perforation peritonitis.

Perforated Blind Pouch: An Unusual Late Complication Following Lateral Anastomosis After a Right Hemicolectomy.

Blind loop syndrome (BLS) is a well-recognized delayed complication in small bowel strictures, stenosis, fistulas, diverticula, or post-gastrectomy afferent loop syndrome. However, due to its delayed presentation, BLS after side-to-side bowel anastomosis is inadequately reported. The vicious cycle of the blind loop is due to bacterial overgrowth, resulting in diarrhea, weight loss, malnutrition, and rarely mucosal erosion, bleeding, and perforation peritonitis. Diagnosis of BLS requires knowledge of previous surgery performed, a high level of clinical suspicion, and experienced radiological abilities. In this case report, we present the clinico-radiological profile of a 54-year-old diabetic patient with a perforated blind ileal pouch occurring four years after a right hemicolectomy with side-to-side ileo-transverse anastomosis.

Strangulated Epigastric Hernia: A Rare Occurrence.

An epigastric hernia is a rare type of abdominal hernia, described in the literature mostly as small, containing only preperitoneal fat. A large true epigastric hernia with herniation of the abdominal viscera is even rarer. Only a few case reports have given an account of strangulation in such an epigastric hernia. This case report describes a middle-aged, morbidly obese man with a big epigastric hernia presenting with incarceration and acute abdominal pain. Emergency surgical exploration revealed a 7 cm midline defect in the rectus sheath and a 30 cm segment of the jejunum and a 6 cm segment of the transverse colon were gangrenous. The gangrenous bowel segments were resected, and an end-to-end jejuno-jejunal and colo-colic anastomosis were done. The patient had an uneventful postoperative recovery.

A Rare Case of Dorsal Agenesis of Pancreas, Choledochal Cyst, and Hirschsprung Disease in a Young Patient.

Dorsal pancreatic agenesis is a rare congenital pancreatic malformation. There is just 1 reported case associating it with choledochal cyst. However, no cases have reported yet with both coexisting with Hirschsprung disease. We report a case of a 23-year-old man, presenting with on and off epigastric pain, sometimes radiating to the back. His medical records showed he had Hirschsprung disease as a neonate, for which he underwent Duhamel procedure. Ultrasound imaging revealed a choledochal cyst and a nonvisualized distal portion of the pancreas. Further cross-sectional imaging confirmed the findings-a type 1 choledochal cyst and a dorsal agenesis of the pancreas in a patient with Hirschsprung disease.

Swiss Cheese Loin: A Rare Initial Presentation of Pott's Spine.

Spinal tuberculosis (TB) is the most common form of skeletal TB with an exceedingly diverse set of clinical presentations. Most often, there is a slow onset of the disease with patients presenting only with back pain. Although some patients can present later with neurological deficits or with compressive symptoms of an accompanying cold abscess, an initial presentation of a spontaneous cutaneous fistulization of a paraspinal abscess is rare. We present the case of a young boy with such a primary presentation, with no other common symptoms of spinal TB. He was treated with ultrasound-guided percutaneous drainage of the paraspinal abscess and a multidrug anti-tubercular chemotherapy regimen.

Anomalous Pancreaticobiliary Duct Junction in an Unusual Case of Synchronous Gallbladder and Bile Duct Malignancy.

Synchronous malignancies involving the gallbladder and the bile duct are exceedingly rare. Moreover, their association with anomalous pancreaticobiliary duct junction (APBDJ) has been reported mostly from the Far Eastern countries. Over time, many studies have suggested the definite risk of malignancy attributable to the 'carcinogenic anatomical configuration' of the long common biliopancreatic channel, allowing reflux of pancreatic juices in the biliary tract. In this report, we present a case of an elderly man from South India who was initially diagnosed with synchronous gall bladder with bile duct malignancy; the patient turned out to have an APBDJ on further evaluation.

Giant Celiac Artery Pseudoaneurysm in a Case of Chronic Pancreatitis: A Rare Case Report With Literature Review.

Pancreatic pseudoaneurysms though uncommon can result in life-threatening spontaneous acute gastrointestinal or intraperitoneal hemorrhage. Celiac artery pseudoaneurysm in a background of chronic pancreatitis is a very rare event. Digital Subtraction Angiography is an important adjunct in the diagnosis and follow-up with the advantage of providing therapeutic options along with giving other details regarding the site, size, and flow characteristics. It has replaced emergency surgical procedures with the added advantage of fewer postoperative complications and lower morbidity and mortality. An urgent surgical intervention remains the only option when such endovascular management fails, not feasible, or is unavailable. Surgical options include proximal arterial ligation or a pancreatic resection, depending on the location of the pseudoaneurysm. We report a case of a 35-year-old gentleman, a known patient of chronic pancreatitis, who presented to our emergency with clinical features of hypovolemic shock and was diagnosed to have celiac artery pseudoaneurysm. Following a failed endovascular coiling, he was successfully managed with operative celiac artery ligation.
