Laparoscopic surgery: surgical education in the People's Republic of China.

In 1991, because of the international emphasis on laparoscopic surgery, a large contingency of surgeons took on the task of introducing laparoscopy to the People's Republic of China. This trip was a technological feat, since all of the equipment and instrumentation had to be carried into the country. This necessitated a major coordinated effort among professional teaching staff and industry representatives with their transported equipment. This unique educational opportunity is detailed in this article, which highlights, in particular, the contrast between the new "high-tech" surgery and the reality of a developing country.

Mini-lap cholecystectomy.

With the introduction of laparoscopic cholecystectomy, the surgical community witnessed a revolution in basic ideology. Gone are the days when surgeons spoke of wounds healing "from side to side, and not top to bottom." The surgical community has become aware of the concept of minimally invasive surgery. Despite this recent advance, surgeons have long realized that the surgical wound does contribute to morbidity and mortality. The mini-lap cholecystectomy, described as early as 1982, is an indication that surgeons are making an attempt to reduce this morbidity. Mini-lap cholecystectomy is now being suggested as an alternative to laparoscopic cholecystectomy--a technique that boasts many of the same benefits without the problems inherent in laparoscopic surgery. The author has reviewed the literature for mini-lap cholecystectomy, laparoscopic cholecystectomy, and conventional cholecystectomy. Using this "historical" database, he then compares the three techniques to determine whether mini-lap cholecystectomy is a viable alternative.

Laparoscopic cholecystectomy.

With more than 500,000 cholecystectomies performed per year, great interest has developed in laparoscopic cholecystectomy. The procedure offers the patient reduced hospital stay, faster return to work, less pain, and improved cosmetic results. In September 1988, we developed a technique of performing laparoscopic cholecystectomy that we have now performed in more than 800 cases with good results. The technique allows the surgeon to fully evaluate the common duct via operative cholangiography and has allowed us to use a laparoscopic approach in all patients who were candidates for cholecystectomy. The technique offers a minimally invasive alternative to open cholecystectomy.

Laparoscopic cholecystectomy in the pediatric patient.

Since June 1990, five girls and one boy have been evaluated for biliary colic. Gallstones were documented by sonography. Two girls, ages 8 and 14 years, had hereditary spherocytosis, and a 9-year-old boy had sickle cell disease. The other three girls, ages 13, 13, and 15 years, developed cholelithiasis and biliary colic without a history of hematological disease. Three children weighed less than 90 lb, with the smallest weighing 45 lb. All patients underwent laparoscopic cholecystectomy without complications. Operative cholangiography was performed in five of the six children. The KTP-532 laser was used for dissection of the gallbladder from the liver bed in two patients, and electrocautery was used in the remaining four. The average operating time was 1 hour 45 minutes. This is a report of the use of laparoscopic cholecystectomy in pediatric patients. The advantages of its use include a shorter hospitalization, decreased postoperative discomfort, and a much shorter interval between the surgical procedure and return to normal activities such as school and play. At this time, it is recommended for those children without complications from their cholelithiasis such as common duct obstruction and gallstone pancreatitis.

Laparoscopic laser cholecystectomy: analysis of 500 procedures.

Laparoscopic laser cholecystectomy (LLC) is a less morbid alternative to open cholecystectomy. The advantages of laparoscopic techniques associated with advances in laser technology have heralded a dramatic advancement in the surgical treatment of biliary disease. Earlier return to work, lower morbidity, and lower medical expense are known advantages of laparoscopic surgery. We present the findings of our initial 500 procedures. The outcome of the first 200 procedures is compared to the following 300 procedures. Operating time averaged 88 min, and cholangiograms were achieved in 79%. Thirty-two percent were performed as outpatients and average hospital stay was 0.98 days. Conversion to open cholecystectomy occurred in 1.8% of cases and there were 5 major complications related to the procedure. No wound infections and no respiratory complications were encountered. There were no mortalities. Management of common bile duct stones with combined surgical and endoscopic modalities are discussed.

Laparoscopic cholecystectomy: cost analysis.

Recently laparoscopic cholecystectomy (LC) has become an accepted alternative to the traditional open cholecystectomy (OP). The purpose of this study was to compare laparoscopic cholecystectomy to open cholecystectomy with respect to four variables: (a) operative time, (b) length of hospital stay, (c) total hospital cost, and (d) morbidity and mortality rates. The most recent 200 LCs performed at HCA West Side Hospital were selected for comparison in the study. Demographic data, including age and sex were collected for all patients. The medical record for each patient was then reviewed to obtain the study variables. A control group of 200 patients undergoing elective open cholecystectomy over the same period was selected. Complications occurred in 12 patients (6.0%) in the LC group with one postoperative mortality. Nineteen patients (9.5%) suffered complications in the OC group with no operative mortality. The difference between the two groups was not statistically significant. The average length of operation (recorded in minutes) in the OC group was 87.79 (SD +/- 20.69) as compared to 103.78 (SD +/- 29.01) in the LC group. This difference proved to be slight, but significantly greater (p < 0.0001). The average length of stay (recorded in days) in the OC group was 4.43 (SD +/- 1.29) versus 1.13 (SD +/- .93) in the LC group. Again, the difference proved to be statistically significant (p < 0.0001). The corrected average total hospital charge from OC was $3,006 (SD +/- 755) versus $2,312 (SD +/- 484) for LC, a difference that was statistically significant (p < 0.0001). Laparoscopic cholecystectomy is a safe, effective, and cost-efficient alternative to open cholecystectomy.(ABSTRACT TRUNCATED AT 250 WORDS)

Outpatient laparoscopic laser cholecystectomy.

Laparoscopic laser cholecystectomy has been performed clinically in the United States since 1988. After refinement of the technique, the procedure was offered on an outpatient basis. Eighty-three patients underwent laparoscopic laser cholecystectomy during the study period. Thirty-seven (45%) had the procedure as an outpatient. Younger patients were more suited for the outpatient procedure and those without previous surgery were more likely to have the procedure done as an outpatient. Weight, operating time, and gallbladder pathology were similar, although patients with acute inflammation of the gallbladder were more likely to require hospitalization. The primary reason for patient admission was patient preference.

Laparoscopic laser cholecystectomy. A comparison with mini-lap cholecystectomy.

The standard treatment of cholelithiasis in the United States is surgical removal of the gallbladder, but this treatment often has a major economic impact on the patient: major surgery, lengthy hospitalization, and several weeks' absence from work. Because of this economic factor, there has been a movement toward non-invasive methods, but they, too, have their drawbacks: long-term medical therapy; a high risk of stone recurrence because the diseased gallbladder is still in place. We therefore developed a means of performing a cholecystectomy through a laparoscope using laser technology, the results of which are compared here with the results in a series of "mini-lap" cholecystectomies that we also performed during the same time period.

Complications of laparoscopic herniorrhaphy.

Anterior inguinal hernia repair is the second-most-commonly performed abdominal operation and has been associated with low morbidity and mortality rates. The principle of laparoscopy has been applied to this surgical problem in a series of 762 patients with 841 inguinal hernias. Four types of laparoscopic repairs were conducted: (1) high ligation of the indirect inguinal hernia sac and closure of the internal ring (87 patients with 89 hernias); (2) plug and patch of the internal ring (74 patients with 87 hernias); (3) transperitoneal suture repair of the transversalis fascia to the iliopubic tract or Cooper's ligament (28 patients with 30 hernias); and (4) placement of a large prosthesis over the myopectoneal orifice (563 patients with 635 hernias). These early results indicate that the overall complication rates were low, especially when a large prosthesis was used to reinforce the myopectoneal orifice. It is concluded that laparoscopic inguinal herniorrhaphy is a safe and effective procedure with which to manage this surgical problem.
