The difficult gallbladder is the most common 'difficult' laparoscopic surgery being performed by general surgeons all over the world and the potential one that places the patient at significant risk. Although the rate of conversion to open surgery and the complication rate are low in experienced hands the surgeon should keep a low threshold for conversion to open surgery and it should be taken as a step in the interest of the patient rather than be looked upon as an insult to the surgeon.Various preoperative factors can help in deciding the”difficult gall bladder”and conversion to open cholecystectomy. The aim of this study was to predict difficulty of LC and the possibility of conversion to open cholecystectomy (OC) before surgery using the clinical and ultrasonographic criteria in our set up. Male gender, single large stone, thick walled gall bladder, previous abdominal surgery and contracted gall bladder are the factors which proved to be significant factors in our study. 07/11/2020 05:08:06 am Endoscopic resection of malignant sinonasal tumours: Current trends and imaging workup. http://www.oapublishinglondon.com/article/1106 Introduction Modern advances in endonasal endoscopic surgery have expanded its utility in the management of malignant sinonasal tumours, and the degree to which cases are eligible. Knowledge of the indications, inclusion & exclusion criteria, and imaging workup that empowers judicious patent selection is essential. Conclusion Studies describing impact of patient quality-of-life will surely affect the fate of endoscopic resection, but the current trend suggests that this technique stands to replace an open approach when outcomes are similar. Combined craniofacial/endoscopicand craniofacial-only approaches to sinonasal malignancy remain an important option in the management of complex disease. 07/11/2020 05:08:06 am Stereotactic radiotherapy of pancreatic cancer: techniques and results. http://www.oapublishinglondon.com/article/1107 Introduction. Stereotactic body radiotherapy (SBRT) in the treatment of pancreatic carcinoma is a recent technique. Aim of this analysis is to present a summary of techniques and clinical results. Material and methods. SBRT allows to perform a local treatment of the tumor in shortened time (1-5 days) compared to traditional treatments (about 1 month) but  requires complex planning and delivery techniques with specific accessories for image guided radiotherapy. The studies published to date are characterized by small series and very different methods in terms of dose, fractionation, techniques and evaluation modalities. Results. The preliminary published results are positive in terms of tumor response (ORR: 50%) and local control of the tumor (crude rate: 80%). However, gastrointestinal toxicity seems to be the main limitation of SBRT, especially at the duodenal level. Conclusions. If SBRT of pancreatic carcinoma will be standardized and optimized, reducing the risk of bowel toxicity, in the future it may have an increasing role in the field of integrated treatments of this tumor. 07/11/2020 05:08:06 am Gastrointestinal complications of Roux-en-Y gastric bypass surgery. http://www.oapublishinglondon.com/article/1365 The article has been forwarded to the production team.

Some of the main questions regarding the safety and efficacy of minimally invasive surgery for rectal cancer is whether an equivalent total mesorectal excision, lymphadenectomy, circumferential resection margin involvement, local recurrence, disease free survival, and overall survival can be obtained in comparison to conventional open surgery. Materials / Methods We have systematically reviewed all current randomized controlled trials in the literature comparing minimally invasive and conventional open surgery for rectal cancer. Results Studies reviewed in this paper revealed comparative oncologic results and outcomes, though most are single institution studies with small sample sizes, and long term outcomes are scarce. Conclusions Larger multi-institutional studies such as ASCOG Z6051 and COLOR II will help us answer the question regarding long term oncologic results in regards to minimally invasive surgery for rectal cancer. Until then, it is recommended that minimally invasive surgery for rectal cancer be conducted within a randomized controlled trial. 07/11/2020 05:08:06 am
