Summary
Microlaparoscopic cholecystectomy using smaller 3.5-mm trocars significantly reduces incisional pain and improves cosmetic outcomes compared to traditional laparoscopic cholecystectomy. This technique is feasible and beneficial for patients undergoing gallbladder removal.
Area of Science:
- Minimally Invasive Surgery
- Surgical Technology
- Gastrointestinal Surgery
Background:
- Minimizing port site incisions in laparoscopic cholecystectomy may alleviate postoperative pain.
- Assessing the impact of reduced trocar size on patient outcomes is crucial for surgical advancement.
Purpose of the Study:
- To compare the efficacy of microlaparoscopic cholecystectomy (3.5-mm trocars) versus traditional laparoscopic cholecystectomy (10-mm and 5-mm trocars) in terms of incisional pain and cosmetic results.
- To evaluate other postoperative outcomes including fatigue, nausea, vomiting, and pulmonary function.
Main Methods:
- A double-blind, randomized controlled study involving 60 patients undergoing cholecystectomy.
- Patients were assigned to either microlaparoscopic cholecystectomy (3.5-mm LC) or traditional laparoscopic cholecystectomy (LC).
- Postoperative pain, fatigue, nausea, vomiting, pulmonary function, and cosmetic results were systematically recorded and analyzed.
Main Results:
- Data from 52 patients were analyzed; 3.5-mm LC significantly reduced incisional pain in the first postoperative week compared to LC (p <0.01).
- Supraumbilical port site pain was higher in both groups, but cosmetic results were significantly better with 3.5-mm LC (p <0.01).
- No significant differences were observed in fatigue, nausea, vomiting, or pulmonary function between the groups.
Conclusions:
- The use of 3.5-mm trocars for microlaparoscopic cholecystectomy is a feasible and safe surgical approach.
- Microlaparoscopic cholecystectomy effectively reduces incisional pain and enhances cosmetic outcomes following gallbladder removal.
- Smaller trocar sizes offer a significant advantage in patient recovery and aesthetic results after laparoscopic cholecystectomy.
