Background : Operative gynecologic laparoscopy has become the preferred method for treating benign gyne-cologic diseases due to its minimally invasive nature and faster recovery compared to laparotomy. However, post-laparoscopic shoulder pain (PLSP) is a common complaint following laparoscopic surgeries, affecting pa-tients' satisfaction and recovery. Various methods have been proposed to alleviate PLSP, but consensus on their effectiveness remains elusive.   
Aim of the Work : This randomized controlled clinical trial aims to investigate the effect of gas drainage by in-traperitoneal drain on shoulder pain in women after lapa-roscopic surgery in comparison to no drain use.  
Patients and Methods: A randomized controlled clini-cal trial involving 120 female patients undergoing laparo-scopic surgery was conducted to investigate the effect of intraperitoneal drainage on postoperative shoulder pain. The patients were divided into two groups: the study group (n=60) with intraperitoneal drain placement, and the control group (n=60) with routine technique and no drain use. Visual Analog Scale (VAS) scores were used to assess shoulder and abdominal pain at different postoper-ative time points.  
Results: The study demonstrated that intraperitoneal drainage significantly reduced postoperative shoulder pain in the first 12 hours after surgery compared to the control group (p < 0.001 at 3 and 6 hours, p = 0.038 at 12 hours). However, no significant difference in shoulder pain was observed between the two groups at 24 hours post-surgery (p = 0.451). The need for postoperative an-algesia was also lower in the drainage group (p < 0.001). These findings align with previous studies suggesting the efficacy of drainage in reducing shoulder pain after lapa-roscopic surgery. 
Conclusion: This study demonstrates the effectiveness of intraperitoneal drainage in reducing post-laparoscopic shoulder pain during the first 24 hours af-ter surgery, consequently reducing the need for postoperative analgesics. These findings support the outcomes of previous investiga-tions, indicating that drain placement may be a valuable strategy to alleviate postoperative shoulder pain in women undergoing gyneco-logic laparoscopy.
