Biliary adenofibroma: a precursor lesion of intrahepatic cholangiocarcinoma

ABSTRACT Biliary adenofibroma (BAF) is an uncommon liver tumor with a high propensity for malignant transformation. The histomorphology of BAF with malignant transformation can show a spectrum of changes ranging from benign, dysplastic to frank malignancy. Thus, the diagnosis of BAF imposes the pursuit of dysplasia/ malignancy focus. We presented a case of intrahepatic cholangiocarcinoma arising from BAF in a 49-year-old woman with detailed histomorphology. We also performed a PubMed database search and tabulated all previously reported cases of BAF with dysplasia/ malignant transformation. A statistic comparison of age, sex ratio, size of the tumor, and survival following complete resection between BAFs with and without dysplasia/ malignancy from the retrieved data is presented. Our analysis did not highlight any statistically significant difference between BAFs with and without dysplasia/ malignancy in age, sex ratio, tumor size, and survival following complete surgical resection. Our study highlights the histopathology and immunohistochemistry of a case of BAF with malignant transformation and highlights the importance of this diagnosis in management. Further longitudinal studies on a larger cohort of patients are required to validate our findings.

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.

Adult diffuse hepatic hemangiomatosis

Abstract Diffuse hepatic hemangiomatosis (DHH) is an uncommon vascular lesion, though hemangiomas are the commonest benign tumors of the liver. The etiology is largely unknown to date; however, its association with giant cavernous hemangiomas (GCH) has been reported in the literature. We present herein, the case of a 37-year-old hypothyroid woman with abdominal fullness for 2 months. The contrast-enhanced computed tomography revealed multiple well-encapsulated lesions involving the liver lobes and was diagnosed as giant cavernous hemangiomas. Most of them, except the deep-seated ones, were enucleated. Histopathological examination highlighted the presence of GCH with irregular margin, replacement of hepatic parenchyma, and presence of multiple micro-hemangiomas suggesting the possibility of DHH further substantiated by retrospective radiological assessment. No extrahepatic vascular lesion was noted, and the post-operative recovery and follow-up were uneventful. Adult DHH is an uncommon entity. The diagnosis of DHH and its distinction from GCH are important from the management and prognostic point of view as recurrence, extrahepatic manifestations, features of consumption coagulopathy, and death from the complications are not uncommon.

Current management of pancreatic trauma.

Background: Although pancreatic trauma is uncommon, it poses a diagnostic and therapeutic challenge. Any delay in diagnosis raises morbidity and mortality. This study highlights the current management and outcome in patients of pancreatic trauma at a single tertiary care center. Methods: This is a retrospective analysis of prospectively collected data of 24 patients diagnosed to have pancreatic trauma. Collected data was analyzed for age, gender, mechanism of injury, hemodynamic status at presentation, initial serum amylase levels, CECT abdomen findings, AAST-OIS grade of pancreatic injury, injury to other organs, management, complications and outcome. Results: The mean age of these 24 patients was 25 years; 19 were male and 5 females. The mechanisms of pancreatic trauma included blunt abdominal trauma in 21 (87.5%) cases and penetrating injury in 3 (12.5%). Seven (29.16%) patients were managed by non-operative management and 17 (70.83%) underwent surgery. Complications were more frequent in the operative group as compared to the non-operative group. Neither endocrine deficiency nor any mortality was noted in the non-operative management group; while there were 2 cases of endocrine deficiency and 3 mortalities in the operative group. Conclusions: Pancreatic trauma is more common in young male patients and more commonly inflicted by motor vehicles accidents. Low grade blunt pancreatic injury in hemodynamically stable patients and selected patients with high grade blunt pancreatic injury can be managed successfully by non-operative management with no increase in morbidity or mortality and most patients with high grade blunt pancreatic injury and those having penetrating injuries need surgical intervention.

Radical surgery for incidental cancergallbladder after laparoscopic cholecystectomy.

Objective: To report our experience in the management of incidentally detected carcinoma gall bladder and establishment of a treatment protocol. Method: Retrospective review of 7 patients with incidentally detected carcinoma gall bladder during and after laparoscopic cholecystectomy for presumed benign disease. Clinical and histopathological data, treatment and long term outcome of all seven patients were reviewed. Exploratory laparotomy and radical surgery with curative intent consisting of liver resection, lymphadenectomy of the pedicle and excision of the port site were performed in all patients. Results: Liver resection including the segments IVB and V was done in 5 patients and in 2 patients resection of a wedge of hepatic parenchyma of more than 2 cm thickness including the gall bladder bed was carried out. Five patients underwent common bile duct excision with hepaticojejunostomy. Postoperatively, 2 patients developed fever and 1 patient had minimal altered blood in the nasogastric tube aspirate. These were successfully managed conservatively. All 7 patients had disease of pathological stage II and beyond. All patients received adjuvant chemotherapy. One patient died after 2 months of cholangitis and sepsis. One patient succumbed to metastatic disease after 12 months. The remaining patients are disease free on follow up. Conclusion: Re-exploration and aggressive resection with adjuvant chemotherapy for incidental carcinoma of the gallbladder is safe and offers hope for long term survival.

Comparative study of low pressure versus standard pressure pneumoperitoneum in laparoscopic cholecystectomy - A randomised controlled trial.

Introduction: Standard pressure pneumoperitoneum for laparoscopic cholecystectomy employs a pressure range of 12-14 mm Hg. An emerging trend has been the use of low pressure pneumoperitoneum in the range of 7-10 mm Hg in an attempt to lower the impact of pneumoperitoneum on the human physiology while providing adequate working space. Our study proposes to compare the use of low pressure pneumoperitoneum with the use of standard pressure pneumoperitoneum. Methods: A randomised controlled trial consisting of 60 patients with symptomatic gallstone disease who underwent laparoscopic cholecystectomy, of which 30 patients were subjected to standard pressure pneumoperitoneum during the procedure and 30 patients to low pressure pneumoperitoneum. Results: Both groups were comparable in all aspects. The mean operating time with low pressure pneumoperitoneum was 49.07 ± 5.72 minutes and with standard pressure pneumoperitoneum was 46.43 ± 6.92 minutes. There was no statistically significant change in blood pressure, heart rate, pain at 6 hours, need for additional analgesia or shoulder tip pain with the use of lower pressure pneumoperitoneum. Conclusions: Low pressure pneumoperitoneum benefits the patient in the form of lower intensity of postoperative pain but it does not positively impact intraoperative hemodynamics.

Evaluation of the role of prophylactic antibiotics in elective laparoscopic cholecystectomy: a prospective randomized trial.

At present the use of prophylactic antibiotics in elective laparoscopic cholecystectomy is controversial. This prospective study was carried out to define the role of prophylactic antibiotics in elective laparoscopic cholecystectomy to prevent postoperative infection. Ninety three patients were randomly placed in two groups. Group A comprised of 40 while group B consisted of 53 patients. Patients in Group A received 1.5 grams of second generation cephalosporin (cefuroxime sodium) diluted in 100ml of normal saline, at the time of induction of anesthesia. Group B patients received an equal volume of normal saline only. A sample of gall bladder bile was collected by direct gall bladder puncture intra-operatively for aerobic and anaerobic culture. Age, sex, weight of the patient, American Society of Anesthesiologists classification grade, presence of diabetes mellitus, episodes of colic 30 days preceding surgery, intra-operative gall bladder rupture, stone and / or bile spillage, results of bile culture, gall bladder histology, length of hospital stay, and number of septic complications were recorded and analyzed. In group A, one patient (2.5%) had post operative wound infection and in group B, two patients (3.8%) had post operative infection which was statistically similar (p>0.1). There was no difference between the two groups in terms of demographic, intra operative and post operative denominators. Therefore the study concluded that prophylactic antibiotics did not have a significant role to play in prevention of postoperative wound infection in elective laparoscopic cholecystectomy.

Relevance of day care laparoscopic cholecystectomy in a developing nation.

Feasibility, safety and success of day care laparoscopic cholecystectomy (DCLC) has been well established in advanced countries. The information on (DCLC) is not available from developing nations. All patients of gallstone disease undergoing laparoscopic cholecystectomy under the care of the two participating surgeons at the post graduate Institute of Medical Education & Research were considered for day care laparoscopic cholecystectomy. The selection criteria were: elective cases only, patients less than 70 years, American Society of Anesthesiologists (ASA) grade I and Grade II, living within 20 Kilometers of the hospital, availability of a responsible adult carer at home, access to a telephone and a means of transportation to hospital if needed. Clinical and operative data were recorded prospectively. All patients were discharged 6 to 8 hours after surgery with the advice to contact the surgical team over phone whenever necessary or on the day after discharge. Out of the total 236 laparoscopic cholecystectomy performed over a period of 26 months, 106 patients (44.9%) underwent laparoscopic cholecystectomy as day care procedure. Five patients (4.8%) were admitted after surgery. Four patients were admitted because of conversion and one patient was admitted because of suspected myocardial infarction. Hundred and one patients (95.2%) were discharged on the same day. There was no major morbidity and patient's acceptance was high. Day care laparoscopic cholecystectomy is feasible, safe, and acceptable to patients.

Postoperative pulmonary function in laparoscopic versus open cholecystectomy: prospective, comparative study.

BACKGROUND: Pulmonary complications remain a leading cause of morbidity after major abdominal operations. OBJECTIVE: To compare pulmonary function and the frequency of pulmonary complications after laparoscopic cholecystectomy (LC) and open cholecystectomy (OC). METHODS: Fifty-five patients with symptomatic gallstone disease undergoing elective cholecystectomy (LC 40, OC 15) under general anesthesia were evaluated using pulmonary function tests (forced vital capacity [FVC], forced expiratory volume at 1 second [FEV1], and forced expiratory flow at 25% to 75% [FEF25% -75%], chest X-ray and pulse oximetry before and after surgery. RESULTS: FVC, FEV1 and FEF25% -75% decreased by 21.5%, 21.2% and 30.3%, respectively, on postoperative day 1 following LC, and by 44.3%, 46.2% and 58.3%, respectively, after OC. Chest X-ray showed atelectasis in 15% of patients undergoing LC and 45% of those with OC. CONCLUSION: Impairment in pulmonary function after LC was less marked than after OC.

Primary small bowel melanoma: a case report.

The small intestine is the most common site of gastrointestinal metastasis from cutaneous melanoma. However, the small intestine itself is rarely the site of a primary melanotic tumour. We describe a case of primary small bowel melanoma in a 70-year-old man, and discuss the features of primary and metasttic melanoma.

Multiple spontaneous enterocutaneous fistulae in malakoplakia.

Malakoplakia is a rare chronic inflammatory disease, usually involving the urogenital tract. We report a patient who presented with a psoas abscess, and later developed colocutaneous fistula at the site of abscess drainage and multiple spontaneous fistulae away from the site of incision. Histology of the resected specimen showed Michaelis-Gutmann bodies, which are diagnostic of malakoplakia.

True epiphrenic diverticulum of esophagus secondary to tubercular adenitis.

Ephiphrenic esophageal diverticulum is rare and usually is a pulsion-type pseudodiverticulum that occurs in association with motility disorders of the esophagus. We report a 35-year-old man with tubercular lymphadenitis causing true traction type of epiphrenic diverticulum. Esophageal diverticulectomy and esophagomyotomy was done; he is doing well on antitubercular drugs.
