Study of Left Side of Laparoscopic Cholecystectomy

Cholecystitis

cholecystectomy, Laparoscopic

Prospectively selected 100 cases of patients who suffered from gallstones ro cholecystic polypus and treated with laparoscopic cholecystectomy in our hospital. Randomly divided into the experimental group and the control group. The experimental group preserve the main cystic artery, and the control group treated with conventional laparoscopic cholecystectomy. Collection of statistics: including general data(gender, age, BMI, etc.), time of surgery, intraoperative blood loss, incidence of surgical complications (delayed hemorrhage, biliary injury, etc.) and postoperative pain score, etc.

1. research object (1)patients who suffered from gallstones ro cholecystic polypus. (2)Informed and consented to participate in this clinical trial (3)Number of enrolled cases：100.（About 700 cases were treated in our hospital） 2. Inclusion criteria (1) consistent with the indications of cholecystectomy (2) no cholangitis or pancreatitis (3) no diabetes (4) the operation time is less than or equal to 1 hour 3.Exclusion criteria 1. patients with acute cholecystitis 2. cystic arterial variation causes related complications 3. patients receiving analgesic drugs after surgery 4.research methods 4.1 Grouping method: random number table method was applied to randomly divide into 2 groups. 4.2 surgical method：Laparoscopic cholecystectomy with the preservation of the main cystic artery 1. General anesthesia, use laryngeal mask 2. making CO2 pneumoperitoneum through the superior border of umbilical pneumoperitoneum pressure 12 -- 14 mmHg(1 mmHg=0.(133 kPa), the puncture sleeve was placed under laparoscopy according to the three-hole method. 3. To expose the gallbladder triangle, cut the serous membrane of the triangular region along the gallbladder tube, expose the neck and the left half of the gallbladder tube, push the rest tissue of the triangular region (including the main cystic artery, etc.) to the right, and separate the right half of the gallbladder tube, exposing the whole gallbladder tube. 4. Cutting off after clipping the gallbladder tube; 5. Turn up the gallbladder neck, cut off the superficial and deep branches of the gallbladder artery by electric hook along the gallbladder wall. 6. Remove the gallbladder. through the umbilical hole and close the puncture hole. 4.3 main outcome measures (1) General data of patients (gender, age, BMI, etc.); (2) Operation time, intraoperative blood loss, surgical complications (delayed hemorrhage, biliary tract injury, etc.) incidence.
