Background: SILS is a newer laparoscopic technique emerging in this era. So this article aims to provide an overview on safer surgical skills by understanding basic principles and proper application of energy source and endosuturing techniques. Materials and methods: Articles of relevant studies are explored from Google, HighWire Press, PubMed, SpringerLink using keywords-single incision laparoscopy surgery (SILS), energy source in SILS, suturing in SILS. Aim: The main aim is to evaluate the best energy source which can be used in SILS with better ergonomics and to define the good suturing technique in single port laparoscopic surgery. Results: Most of the studies show that newer energy devices, such as LigaSure, harmonic and EnSeal, are being used with advantage of less smoke, less operative time, very minimal blood loss, less drop in hemoglobin value postoperatively, and reduced duration of hospital stay. Endosuturing using roticulators, Endostitch is easier, though intracorporeal and extracorporeal knotting can also be perfomed same like conventional laparoscopy. Conclusion: LigaSure, harmonic and EnSeal can be safely used as multifunctional devices in the available space in SILS without changing the instruments frequently as in conventional laparoscopy. Both intracorporeal and extracorporeal knot can be put by practice and with aid of newer suturing devices.

Background: Xanthogranulomatous cholecystitis is a benign disease of gallbladder which presents almost classically similar with the chronic calculus cholecystitis, but it mimics GB carcinoma intraoperatively. Materials and methods:In our study, 54 cases were found in a study period of 2 yr in which histopathological reports was xanthogranulomatous cholecystitis whether the pt underwent lap/radical/open or lap converted open cholecystectomy for cholelithiasis and chr. cholecystitis and suspicious carcinoma GB. They were retrospectively analysed for getting an idea preoperatively to differentiate them on clinicoradiological ground and while during surgery. Datas were Results and Observation: retrospectively analysed and observed that clinical and biochemical features are non specic. Imaging in the form of USG and CT does help but not to that much extent to accurately diagnose them. intraoperatively presence of dense adhesion and loss of fat plane to surrounding structures creates a big dilemma for the operating surgeon and multiple frozen section biopsy can be of immense help here in guiding further treatment course .Frozen section analysis was not present at our institution so we did not avail its use. Our study is an attempt to derive any correlation Conclusion: between clilnicoradiological and intraoperative aspects preoperatively for the diagnosis of xanthogranulomatous cholecystitis. Although its incidence is greater here than other countries due to rising gallbladder diseases but till this time it is concluded that neither clinical nor radiologically xanthogranulomatous cholecystitis can be ruled out preoperatively. Only histopathological diagnosis is absolutely correct, and in our study we concluded that histopatholigal diagnosis is still the gold standard.
