Laparoscopic cholecystectomy (LC) significantly improves postoperative pulmonary function and reduces pain compared to open cholecystectomy (OC). This leads to fewer complications and faster recovery, making LC the preferred choice for elective gallbladder removal.

Area of Science:

  • Surgical Innovation
  • Pulmonary Medicine
  • Comparative Effectiveness Research

Background:

  • Assessing the impact of surgical techniques on patient recovery is crucial.
  • Pulmonary complications are a significant concern following abdominal surgery.

Purpose of the Study:

  • To prospectively compare laparoscopic cholecystectomy (LC) and open cholecystectomy (OC) regarding their effects on postoperative pulmonary function.

Main Methods:

  • 40 patients undergoing elective cholecystectomy were randomized into LC or OC groups (20 each).
  • Pulmonary function tests, oxygen saturation, and chest X-rays were conducted pre- and post-operatively.
  • Narcotic use and pulmonary complications were compared using statistical analysis (t-test, ANOVA, chi-squared).

Main Results:

  • LC demonstrated a 30-38% reduction in postoperative pulmonary impairment across all measured lung function parameters and oxygen saturation compared to OC.
  • Pulmonary function recovery to baseline was 4-10 days faster with LC.
  • Fewer pulmonary complications (atelectasis, hypoxia) and an eight-fold decrease in postoperative pain medication were observed in the LC group.

Conclusions:

  • Laparoscopic cholecystectomy significantly mitigates pulmonary function compromise and reduces narcotic requirements versus open cholecystectomy.
  • LC leads to a lower incidence of postoperative pulmonary complications.
  • LC is recommended as the preferred surgical approach for elective cholecystectomy due to improved pulmonary outcomes and reduced pain.
