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.

A Randomized Controlled Trial Comparing Ultrasonography-Guided Needle Aspiration and Surgical Drainage for the Management of Breast Abscess.

Background A breast abscess is a localized collection of inflammatory exudate in breast tissue. It is more common in lactating women. Treatment of the breast abscess is usually by incision and drainage, which is accompanied by extensive trauma, lengthy surgical incisions, psychological distress, surgical scar, and discomfort during dressing changes. Recent research has shown that ultrasonography-guided needle aspiration is an alternative to incision and drainage for breast abscess treatment, has superior cosmetic outcomes, and has fewer costs. However, there are no clear guidelines for the same. The primary objective of this study was to assess and contrast the outcomes and efficacy of two approaches in the treatment of breast abscesses: ultrasonography-guided needle aspiration and conventional incision and drainage. Methods This was a single-center, prospective, randomized, controlled, non-inferiority trial. Patients with breast abscesses were randomized either to receive needle aspiration or incision drainage. Patients with lactational breast abscesses were encouraged to breastfeed from either breast. The antibiotic was given for 10 days to all the patients. The study's main focus was on the primary outcome, which was the failure rate. Additionally, several secondary outcomes were examined, including postoperative pain, time required for healing, presence of residual abscess or recurrence, formation of fistulas, and the assessment of scar appearance. Results A total of 44 patients were randomized to 23 and 21 in each arm. There was no statistical difference in treatment failure (p-value=0.862), fistula formation (p-value=1.00), and recurrence (p-value=1.00). There was a significant statistical difference in healing period (p-value <0.001), scar formation (p-value <0.0001), continuation of breastfeeding (p-value=0.005), and clinical resolution (p-value=0.002). There was a significant reduction in post-intervention pain in the needle aspiration group than in the other group (p-value <0.001). Conclusion This study showed a significant difference in postoperative pain, healing time, the continuation of breastfeeding, and scar formation in the needle aspiration group, favouring minimally invasive treatment for breast abscess. However, due to the small sample size, we could not conclude that ultrasonography-guided needle aspiration of the breast abscess is non-inferior to the conventional incision and drainage.

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.

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.
