“…Worldwide, male sex has been described to be associated with dif icult LC [8]. Other studies with large sample number has no signi icant relation between sex and dif iculty similar to results by Chndio, et al but this is in contrast with many studies and literatures showed signi icant association [9].…”

“…In our study, there was statistically signi icance in the relation between male sex and dif iculty of LC. Unequal distribution of patients on the basis of sex could have altered the results in the study Conversion rate and signi icantly higher mortality has been reported in male sex [9]. Only three males converted to open cholecystectomy due to un-controllable bleeding from cystic artery and bile and stone spillage intraperitoneal.…”

Background: Laparoscopic cholecystectomy (LC), is one of the most commonly performed surgical procedures worldwide, it is accepted as the gold standard in the treatment of symptomatic gallstones for its minimal invasiveness, less pain and early recovery. Purpose: To predict the diffi culty of laparoscopic cholecystectomy in patients according to the recently published scoring system and select the diffi cult cases to be done by a senior surgeon. Patients: This is a prospective cohort study. This study took place Oct 6th University Hospital and Kasr El Aini Hospital, Cairo university; the study involved 120 patients admitted with calcular cholecystitis, arranged for laparoscopic cholecystectomy. Methods: Laparoscopic cholecystectomy after applying the scoring system. Results: In our study we found that age, sex and ultrasonographic data were signifi cant predictive factors for assessment preoperatively diffi cult cases that will be operated upon. We found 14 patients above 50 years who scored to be diffi cult and very diffi cult were at outcome diffi cult, only three patients converted to open surgery over fi fty. Conclusion: We can report that obese patient who were over fi fty with history of previous upper abdominal surgery and ultrasonographic picture showed thick walled GB and pericholecystic collection had high risk of conversion. At this study scoring system was used for prediction of diffi cult laparoscopic cholecystectomy sensitivity was 93.75% and specifi city was 52.94% of the scoring system at score 5 for prediction of easy or diffi cult laparoscopic cholecystectomy.

“…LC is a preferred treatment for gall stone disease and has proven to be quite advantageous over open surgery. 17,23 However, some factors like patients advancing age, severe inflammation, history of previous abdominal surgery, obesity, male gender, severe cardiovascular disease, complications during surgery, etc often necessitate conversion of LC to OC. 10,11,18 Several research studies have evidenced that higher surgical difficulties experience in men during LC and increased conversion rates as compared to women.…”

Background: Currently, laparoscopic cholecystectomy is one of the most desirable procedures to treat symptomatic gallstone disease. Yet, various risk factors govern its conversion to open surgery. The impact of male sex as a risk factor for conversion has been a questionable issue. The study aimed to evaluate the role of male sex on outcomes of laparoscopic cholecystectomy.Methods: As per inclusion and exclusion criteria, medical records of all the patients aged 18-70 years who underwent elective LC for a period of 14 months were accessed retrospectively. Data related to patients’ demographic details, intra-operative and post-operative findings was recorded and subjected to analysis.Results: Out of 232 selected cases, 17.67% were males and 82.32% were females. Mean age in both gender groups was similar (p=0.139). Body mass index was also found to be similar in both the groups (p=0.232). There was no significant difference (p=0.85) in the mean operative time between men (29.37±9.29) and women (28.88±15.66). Conversion to open surgery was seen only in female group (1.57%) but it is not significantly from the male group (p=0.42). No significant difference was observed in both groups regarding unwanted intra-operative events (p=0.231) and post-operative complications (p=0.70) and post- operative stay (p=0.50).Conclusions: This study suggests that male gender may not be considered as an independent risk factor for outcome of laparoscopic cholecystectomy. However, extensive research in future may cast further light on this issue.

“…Data were gathered from cryogenic tests on triaxially stressed rock cubes proves that the system works adequately (More data available in Alqahtani (2015)). With the experimental system developed, high-quality data can be gathered to provide a deeper understanding of cryogenic fracturing and advance the cryogenic fracturing processes toward successful field applications.…”

Highlights• A laboratory system for cryogenic fracturing under true-triaxial loading is developed.• Cryogen is flown through boreholes by a coaxial assembly under controlled pressure.• Designs for physical parameter measurements at cryogenic temperatures are optimized.• Acoustic, pressure decay, and breakdown tests effectively capture cryogenic fractures.• Data shows the laboratory design works adequately for cryogenic stimulation studies. AbstractThe concept of cryogenic fracturing is that a sharp thermal gradient developed by applying a cryogenic fluid on a rock surface causes a strong local tensile stressthat initiates fractures. Prior field tests suggest that field application with special equipment rated for cryogenic temperatures may deliver potential benefits. The tests did not, however, identify the fracture mechanisms at work in downhole conditions. In this study, we present our laboratory designs and procedures developed for studying cryogenic fracturing mechanisms in a well environment, and examine typical data indicative of the performance of the system. The experimental apparatus and procedures were specifically designed to conduct cryogenic fracturing tests in specimens under confining stress, with integrated cryogen transport, measurements, and fracture characterization.A true-triaxial loading system was built to simulate reservoir stress levels and anisotropic stress application, and was designed to avoid thermal stresses in tests involving cryogen by arranging discrete components in an open chamber. To maximize thermal shock on the wellbore surface, tubing and wellhead are configured so that liquid nitrogen enters the borehole and flow out after contributing to thermal shock.The temperature at boreholes and along flow lines, borehole pressure, and liquid nitrogen consumption are monitored throughout treatments. Acoustic transmission and pressure-decay measurements are used to characterize fractures before and after the experiments. Breakdown tests performed on un-stimulated specimens and stimulated specimens compare breakdown pressures of the two groups and thus evaluate the performance of thermal fracturing. The laboratory design was able to effectively apply cryogenic stimulations to laboratory rock specimens. The characterization methods were able to capture fracture creation and rock property changes due to cryogenic fracturing.
