Background: This study sought to determine the optimal treatment strategy and timing for cholecystectomy in managing gallbladder diseases during pregnancy. It evaluated the effectiveness of conservative management (CM), laparoscopic cholecystectomy (LC), and open cholecystectomy (OC) in pregnancy and compared cholecystectomy outcomes across three trimesters.
Methods: Studies comparing CM, LC, and OC or evaluating cholecystectomy outcomes across trimesters were included in a literature search until February 2024.
Background: This study evaluated the cost-effectiveness of open, laparoscopic, and robotic liver resection.
Methods: A comprehensive literature review and Bayesian network meta-analysis were conducted. Surface under cumulative ranking area values, mean difference, odds ratio, and 95% credible intervals were calculated for all outcomes.
Background: This study compared the cost-effectiveness of open (ODP), laparoscopic (LDP), and robotic (RDP) distal pancreatectomy (DP).
Methods: Studies reporting the costs of DP were included in a literature search until August 2023. Bayesian network meta-analysis was conducted, and surface under cumulative ranking area (SUCRA) values, mean difference (MD), odds ratio (OR), and 95% credible intervals (CrIs) were calculated for outcomes of interest.
Purpose: This study evaluated the accuracy of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) calculator in predicting outcomes after hepatectomy for colorectal cancer (CRC) liver metastasis in a Southeast Asian population.
Methods: Predicted and actual outcomes were compared for 166 patients undergoing hepatectomy for CRC liver metastasis identified between 2017 and 2022, using receiver operating characteristic curves with area under the curve (AUC) and Brier score.
Results: The ACS-NSQIP calculator accurately predicted most postoperative complications (AUC > 0.
Background: This study aims to compare the outcomes of high-volume, medium-volume, and low-volume hospitals performing hepatic resections using a network meta-analysis.
Methods: A literature search until June 2023 was conducted across major databases to identify studies comparing outcomes in high-volume, medium-volume, and low-volume hospitals for liver resection. Bayesian network meta-analysis was conducted, and surface under cumulative ranking area values, odds ratio, and mean difference with 95% credible intervals were reported for postoperative mortality, failure-to-rescue, morbidity, length of stay, and hospital costs.
Introduction: This video manuscript presents a unique case of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) procedure performed in case of a giant hepatocellular carcinoma (> 15 cm in size) whereby both stages were completed via the pure laparoscopic approach.
Methods: This case was performed in our institution in 2022. All data were obtained from the patient's records in our prospectively maintained database.
Introduction: Gallstone(s) impacted at the distal small bowel causing intestinal obstruction as a result of cholecystoenteric fistula is a well-known, albeit uncommon surgical condition. The rare Bouveret's Syndrome, which refers to the proximal impaction of gallstone(s) in the duodenum or pylorus resulting in the gastric outlet obstruction (GOO), has also been described in the literature. However, gallbladder mucocele with extrinsic compression of the duodenum and/or pylorus causing GOO is a separate entity that is extremely rare.

Very often the lack of working space within the common bile duct causing the failure of mechanical lithotripsy would inevitably mean repeat or further invasive procedures.
Presentation Of Case: A patient with large and multiple common bile duct stones underwent ERCP, and initial deployment of a mechanical lithotripter failed due to the lack of working space within the common bile duct.
Background: Dermatofibrosarcoma protuberans (DFSP) is a rare locally advanced soft-tissue tumour that is often misdiagnosed at presentation, resulting in inadequate initial resection, requiring multiple resections and reconstructive procedures. We reviewed our experience and treatment outcomes with this tumour and propose a treatment strategy.
Methods: A retrospective study on 25 patients with 26 lesions treated from 1997 to 2013 was conducted.
Laparoscopic transperitoneal partial nephrectomy for renal hydatid cyst: a case report.
Surg Laparosc Endosc Percutan Tech
August 2012
A 29-year-old female patient with an isolated hydatid cyst in the lower pole of the left kidney presented with a history of weight loss and cloudy, foul-smelling urine. Laparoscopic partial nephrectomy was performed, at which the cyst was removed en bloc. On the fifth postoperative day, she was discharged without any complication.
View Article and Find Full Text PDFLaparoscopy has gained a place in everyday surgical routine as an alternative surgical approach that decreases morbidity and postoperative hospitalization. Single port laparoscopic surgery has been introduced as a further development of laparoscopy. The feasibility and safety of single port laparoscopy is under extensive evaluation in specialized laparoscopic centers.

Herein, we report the first transumbilical single incision laparoscopic pancreatectomy case in a patient who had renal cell cancer metastasis on her pancreatic corpus and tail.
Methods: A 59-year-old female who had metastatic lesions on her pancreas underwent laparoscopic subtotal pancreatectomy through a 2-cm umbilical incision.
