Outcome and Quality of Life in Obese Patients Underwent Laparoscopic vs. Open Appendectomy
Condition: Obesity; Appendicitis Acute
MeSH terms: Appendicitis
Study type: Observational

Summary: 
      Although obesity is a popular reason for choosing laparoscopic appendectomy (LA) versus open
      appendectomy (OA), however, the question of whether there is a difference remains. The goal
      of the present study is to investigate if there is a difference between OA and LA in obese
      patients. In the present study, Fifty-eight obese patients were diagnosed with acute
      appendicitis according to Alvarado score at the department of surgery at Suez Canal
      university hospitals from March 2020 till August 2021were included. The study participants
      were assigned to two groups, after their approval: LA and OA. The investigators hypothesized
      that evaluating the Outcome and Quality of life of laparoscopic appendectomy for the obese
      patients would be a potential step for standardization of the laparoscopic approach for obese
      patients who are arranged for appendectomy.

      2020 till August 2021were included. The study participants were assigned to two groups, LA
      and OA. This study aimed to compare LA and OA regarding intraoperative complications, length
      of hospital stays, post-operative pain, and rate of postoperative complications. Meanwhile,
      using the SF-36 scoring questionnaire, the quality of life was compared between both groups.
    

Intervention name(s): appendectomy
Intervention type(s): Procedure
Intervention description(s): Open or Laparoscopic appendectomy procedure is typically performed under general anaesthesia. in the laparoscopic approach, the main principle is the triangulation of instrument ports to visualize and expose the appendix clearly. The first trocar (10 mm) for the optical device is introduced peri-umbilically, followed by two 5 mm trocars, one in the right lower quadrant just above the pubis (to grasp the appendix) and the other in the left iliac fossa (for the (right-handed) surgeon's right hand), assuming the appendix is in its normal anatomic position. The locations of the 5 mm trocars can be changed based on the anatomic position of the appendix as determined before to surgery (for example a subhepatic appendix could lead to placing the trocars as for cholecystectomy)
