The role of thoracic endovascular aortic repair (TEVAR) has evolved and is now firmly established as a mainstay of therapy for acute complicated type B aortic dissection (acTBAD). However, several important issues remain unresolved including the optimal timing, sizing, graft selection, coverage length and utilization of adjunctive therapies to address false lumen perfusion. Therefore, the purpose of this study was to provide a contemporary perspective on the management and results for TEVAR of acTBAD.
All TEVAR patients (N.=159) with acTBAD from a single high-volume, academic medical center were analyzed. Comparative results across time-dependent cohorts (2005-2009 [N.=43] vs. 2010-2014 [N.=56] vs. 2015-2020 [N.=60]) are presented.
30-day mortality was 13%(N.=21) with a trend towards improvement over time (2005-2009, 18% vs. 2010-2020, 12%; P=0.1). Similarly, incidence of postoperative complications also declined 2005-2009, 70% vs. 2010-2020, 36%(P-trend=0.08). One and 2-year freedom from aorta-related peer reviewed evidence. These results along with the evidence-based review provided herein, provide an update on the management and results of TEVAR of acTBAD while highlighting specific controversies unique to the management of this challenging clinical problem.BACKGROUND The aim of this study was to review outcomes of gamma knife radiosurgery (GKRS) for prolactinoma and report our experience with it. MATERIAL AND METHODS We reviewed the patient database in our center and identified 24 patients with prolactinoma who underwent GKRS from 1993 to 2016. Complete endocrine, clinical, and radiological data were available on these individuals before and after GKRS. RESULTS Data from 5 males and 19 females with a median age of 30.5 years (range, 18.1 to 51.1) were reviewed. The median follow-up was 109.3 months (range, 23.2-269.3). The median margin dose of GKRS was 15 Gy (range, 10.5 to 23.6). In total, prolactin (PRL) normalization after GKRS was achieved in 66.7% of patients. Endocrine remission (normal PRL levels after discontinuation of dopamine agonists) was achieved in 10 patients (41.7%), and endocrine control (normal PRL levels while taking dopamine agonists) was achieved in 6 patients (25.0%). All of the patients showed tumor control. New-onset hypopituitarism post-GKRS occurred in 4 patients (16.7%). No new visual dysfunction or cranial nerve dysfunction were observed after GKRS. CONCLUSIONS For treatment of prolactinomas, GKRS may provide relatively high rates of endocrine remission and tumor control, as well as a low rate of new-onset hypopituitarism. GKRS may be an effective and safe treatment for prolactinomas.
Bariatric surgery, besides causing significant weight reduction, leads to improvement in type 2 diabetes mellitus (T2DM). However, there is a scarcity of data on the prediction of diabetes resolution in non-Western population.
To evaluate the impact of bariatric surgery on T2DM and to assess the accuracy of pre-operative scoring systems in predicting remission.
A tertiary care academic centre, India.
We used a retrospective cohort of all diabetic patients (n = 244) who underwent bariatric surgery at our centre in the past 10 years. The cohort was followed up for diabetes remission, and pre-operative scoring systems were analysed against the observed results.
Of 244 patients, we were able to contact 156 patients. The median period of follow-up was 38 months. The mean body mass index (BMI) of the study group decreased from 45.4 to 33.4 kg/m
(%excess BMI loss = 61.2%). The number of patients dependent on oral anti-diabetic pharmacotherapy and on insulin decreased from 133 (85.3%) to 40 (25.6%) and from 31 (19.9%) to 7 (4.5%), respectively. Remission was analysed for 96 patients, who submitted complete biochemical investigations. The median follow-up period for this sub-cohort was 36 months. 38 (39.6%) patients were in complete remission, 15 (15.6%) patients in partial remission and 34 (38.5%) patients showed an improved glycaemic control. The three pre-operative scores, Advanced-DiaRem, DiaRem and ABCD, showed predictive accuracies of 81.1%, 75.6% and 77.8%, respectively.
Besides leading to excess BMI loss of 61.2%, bariatric surgery also resulted in diabetes remission in 55.2% of the patients. Amongst various pre-operative scores, Advanced-DiaRem has the highest predictive accuracy for T2DM remission.

Here, we report a rare case of retroperitoneal bronchogenic cyst, the location, relationship to adjacent structures and blood supply of which were determined by computed tomography (CT) recombination technology and resected by laparoscope. The case was a 41-year-old female patient. The patient came to the hospital because of intermittent lumbar back discomfort for 1 month. CT scanning revealed a cystic mass of 3.9 cm × 3.2 cm × 3.0 cm behind the left peritoneum. selleckchem The mass was close to the left adrenal gland, and a branch artery from the left renal artery was revealed to supply the mass. The cystic mass was excised by laparoscopy and confirmed as bronchogenic cyst on histopathology.Seroma formation is one the most common occurrence post-ventral hernia repair, with varied presentation from asymptomatic collection to infected collection to chronic collection, which may sometimes present as a diagnostic dilemma and therapeutic challenge. We report a case of giant abdominal swelling presenting as an encysted peritoneal cyst, which was ultimately found to be a chronic seroma and was managed successfully with combined laparo-seroscopic approach.
Laparoscopic cholecystectomy (LC) in patients with extrahepatic portal vein obstruction causing portal cavernoma (PC) is considered high risk because of portosystemic collateral veins in the hepatocystic triangle. The literature is limited to isolated case reports. We describe our experience of LC in patients with PC.
Data of patients with PC who underwent LC for symptomatic gallstones or related complications was reviewed. Patients with simultaneous cholecystectomy with splenorenal shunt and open cholecystectomy were excluded. Pre-operative evaluation consisted of complete blood count, international normalisation ratio and liver function tests, ultrasound of the abdomen with Doppler, contrast-enhanced computerised tomography, magnetic resonance cholangiopancreatography and esophagogastroscopy as indicated. A standard four-port LC was performed. The technical principles followed were to avoid injury to the collateral veins, liberal use of energy sources and division of dominant collateral veins between clips.
