Laparoscopic cholecystectomy: results of first 300 cases in Hong Kong.

Prospective analysis of the first three hundred patients who underwent laparoscopic cholecystectomy was carried out in three surgical centres of Hong Kong. Over a 20-month period, 300 consecutive patients were recruited, including elective and emergency cases. The indications for laparoscopic cholecystectomy were symptomatic gallstones (78%), cholangitis (6%), pancreatitis (5%) and cholecystitis (11%). Patients with common duct stones (12) had preoperative endoscopic sphincterotomy and stone extraction prior to cholecystectomy. Laparoscopic cholecystectomy was accomplished successfully in 287 patients. Thirteen patients (4.3%) required conversion to open cholecystectomy. The reasons for conversion were: inability to identify cystic duct and common bile duct clearly (6); bleeding (5); Mirizzi syndrome (1); and slippage of cystic duct clip (1). The median operation time was 80 min with a range of 28-270 min. The median hospital stay was 3 days. Seventy-five per cent of patients required only a single dose of pethidine injection. None of the patients required blood transfusion. The overall complication rate was 7%. These included mild cellulitis of the subumbilical wound (3%) and postoperative chest infection (3%). One patient developed subphrenic abscess which resolved on percutaneous drainage under ultrasound guidance. Iatrogenic injury to the common bile duct was seen in one patient who had an impacted stone at Hartmann's pouch. With adequate training laparoscopic cholecystectomy can be performed safely. The advantages over open cholecystectomy are less wound pain, better cosmesis and shorter convalescence.

[A cost analysis of laparoscopic cholecystectomy compared with the open technic].

OBJECTIVE: The aim of this study was to compare the cost of laparoscopic cholecystectomy with that of open cholecystectomy. DESIGN: We analyzed the cost of both procedures regarding hospital stay, days of work lost and the cost derived from the morbidity of the complications of each technique in two groups of patients. With these data we were able to calculate direct and indirect costs of both procedures and compare them. RESULTS: Morbidity was similar in both groups and had no influence in the cost; cost of the material used for laparoscopic cholecystectomy was higher; hospital stay and days of lost work were significantly lower for the laparoscopic procedure than for the open one. The total cost of laparoscopic cholecystectomy was 23% cheaper than that of open cholecystectomy. CONCLUSIONS: Laparoscopic cholecystectomy appears to be cheaper than open cholecystectomy. As the laparoscopic technique becomes more widespread its cost might decrease even further.

The outcomes of elective laparoscopic and open cholecystectomies.

BACKGROUND: The demand for evidence of effectiveness for medical care has prompted the development of epidemiologic approaches to relating the outcomes of care to treatment. This study compares the outcomes of care for patients undergoing the newly introduced laparoscopic cholecystectomy with the results from conventional open cholecystectomies. METHODS: Consecutive cases of elective cholecystectomy from 35 hospitals (all of the metropolitan and selected rural hospitals in Minnesota) were enrolled in the study. Patients were interviewed on admission to establish baseline symptoms and functional status and to confirm risk factors. Their medical records were abstracted to yield information on risk factors, treatment, and hospital complications. To establish outcomes, patients were sent a questionnaire about their symptoms and functional status six months postoperatively. RESULTS: Of 3,448 patients studied, 2,490 (72 percent) had a laparoscopic procedure, including 195 cases that were converted to open cholecystectomies. Functional status data were obtained on 2,481 cases (76 percent). Laparoscopic operation was associated with more operative complications (odds ratio 3.02, p < 0.001), but with fewer general complications (odds ratio 0.32, p < 0.001). The mean time to return to work was 15 days for laparoscopic cases compared to 31 days for open procedures (p < 0.001). The only functional outcome difference between the two procedures was that patients who underwent laparoscopic cholecystectomies were more likely than those with conventional cholecystectomies to be able to perform their usual activities at follow-up evaluation (p < .001). There was evidence of a learning curve; the more laparoscopic procedures a surgeon performed, the fewer the operative (p < 0.01) and general (p < 0.0001) complications. There was no indication that the availability of laparoscopic operation was associated with more operations being performed. CONCLUSIONS: Laparoscopic operation seems to represent a significant advance in getting patients back to a normal life sooner. More attention needs to be given to which patients are most likely to benefit from cholecystectomy of either type. Epidemiologic approaches can be useful in assessing the effectiveness of care. Partnerships between providers and researchers can produce useful effectiveness data by supplementing available clinical records with more detailed outcome data.

A prospective randomized comparison of the metabolic and stress hormonal responses of laparoscopic and open cholecystectomy.

BACKGROUND: In a relatively short period of time, therapeutic laparoscopy has become an everyday part of the general surgeon's life. Although laparoscopy provides distinct clinical advantages, it is not yet clear that it lessens the stress response typical of elective surgical procedures, and as such, the morbidity of surgery. The hypothesis that laparoscopic cholecystectomy produces less of a metabolic and stress hormonal response than open cholecystectomy was tested in a prospective randomized trial. STUDY DESIGN: Twenty otherwise healthy women between 18 and 45 years of age with a history of uncomplicated symptomatic cholelithiasis undergoing either laparoscopic (n = 10) or open cholecystectomy (n = 10) were studied. The hormonal response of the adrenocortical (serum adrenocorticotropic hormone, cortisol, and urinary free cortisol), adrenomedullary (plasma and urinary epinephrine and norepinephrine), thyroid (thyroid-stimulating hormone, thyroxine, and triiodothyronine), pituitary (antidiuretic hormone and growth hormone), and glucose (serum glucose, glucagon, and insulin) homeostatic axes were measured serially over a 24-hour period. RESULTS: No difference was seen between the laparoscopic and open groups in operative time (mean plus or minus standard error of the mean, 70 +/- 6 minutes compared with 77 +/- 6.3 minutes) or hospital stay 1.3 +/- 0.2 compared with 1.1 +/- 0.1 days). Assessment of postoperative pain using an analog pain score was less in the laparoscopic group (4.9 +/- 1.3 compared with 12.3 +/- 2.5, p = 0.01). The response of the adrenocortical, adrenomedullary, thyroid, and glucose axes were similar or identical in both groups. Antidiuretic hormone levels were greater in the laparoscopic group at one hour intraoperatively (281 +/- 79 pg/mL compared with 54 +/- 18 pg/mL, p < 0.01), and at extubation (122 +/- 18 pg/mL compared with 36 +/- 7 pg/mL, p < 0.01). Serum glucose levels were greater immediately following laparoscopic cholecystectomy. Glucose and insulin levels were greater at four, 12, and 24 hours after open cholecystectomy. CONCLUSIONS: Elective laparoscopic and open cholecystectomy for uncomplicated cholelithiasis result in similar degrees of perioperative hormonal stimulation. The different hormonal responses in the immediate and later postoperative periods after laparoscopic and open cholecystectomy suggest differential stressful stimuli between the two procedures.

Randomized clinical trial of conventional cholecystectomy versus minicholecystectomy.

BACKGROUND: The main argument for laparoscopic cholecystectomy in preference to open cholecystectomy appears to be based on less traumatic incisions inflicted on the abdominal wall. To investigate the effects of different incision lengths on patients following elective open cholecystectomy, a randomized clinical study was conducted. METHODS: In this study 130 patients were randomly assigned to undergo either open cholecystectomy through a transverse subcostal incision of mean length 5.8 cm, so called minicholecystectomy (65 patients), or to undergo conventional cholecystectomy through a paracostal incision of mean length 13.1 cm (65 patients). The perception of pain after operation was measured by a visual analogue scale. To register late complications the mean(s.d.) hospitalization period after operation was extended to 11.5(1.2) days in the minicholecystectomy group and 15.4(2.5) days in the conventional cholecystectomy group. RESULTS: The perceived pain and analgesic requirements were found to be similar in both groups. Twelve of 65 patients in the minicholecystectomy group and four of 65 in the conventional cholecystectomy group developed wound haematoma. CONCLUSION: On the basis of this prospective randomized study, the hypothesis that a smaller incision length on the abdominal wall could lower the level of perceived pain, and therefore decrease the postoperative analgesic intake after minicholecystectomy, could not be confirmed.

Ambulatory cholecystectomy without disability.

This is a presentation of 200 consecutive outpatient cholecystectomies performed during a 4-year period in a small community hospital. This technique is performed with minor modifications of the usual cholecystectomy procedure so that it could easily be performed by general surgeons throughout the United States. The procedure has resulted in a large reduction in the short- and long-term morbidity associated with cholecystectomy, and in savings of up to one fourth the cost of a routine inpatient cholecystectomy. This procedure allows the general surgeon to treat patients with cholecystectomies in the fashion to which the surgeon is accustomed and still markedly reduce the hospital stay. The morbidity from this procedure seems comparable with laser cholecystectomy. Ambulatory cholecystectomy as described here does not require any special training or equipment.

Hospital reported complications of laparoscopic cholecystectomy among Medicare and Medicaid patients.

The purpose of this study was to initiate a hospital-based case review of all laparoscopic cholecystectomies performed on Medicare and Medicaid patients in New York State in 1991 where there were one or more complications. Another purpose was to facilitate efforts by hospitals to monitor the performance of laparoscopic cholecystectomy through an educational process of data-sharing. There were 2,940 Medicare and 1,108 Medicaid cholecystectomies in New York State in 1991. Of these, 351 (11.9%) Medicare and 107 (9.7%) Medicaid patients were reported as having complications. The complication rate for Medicare patients was slightly lower than that observed (15.8%) in an epidemiologic study of Medicare patients in New York State who underwent laparoscopic cholecystectomy during the period January 1, 1990-June 30, 1991. Both of these observed rates for Medicare patients are higher than the mean 6.0% complication rate reported for open cholecystectomy in the literature. These increased rates may in part be due to age related risk factors present among Medicare patients. The absence of age related risk factors may also largely account for the lower laparoscopic cholecystectomy complication rate (9.7%) observed among Medicaid patients. The complication rate of 9.7% for Medicaid patients is similar to rates reported in other recent studies. The 11.9% complication rate for Medicare patients is higher than that reported in other recent studies. However, careful patient selection, the absence of age related risk factors, and greater surgical experience may account for the lower complication rates reported in some published series. Overall, the coding of complications was found to be accurate. The coding of laparoscopic cholecystectomy was found to be slightly flawed.(ABSTRACT TRUNCATED AT 250 WORDS)

Adenomas of the large bowel after cholecystectomy. A case-control study.

Cholecystectomy has been reported to be more common in patients with colon cancer. Since adenomas are believed to be precursors of colon cancer, we evaluated the association of cholecystectomy and adenomas in a case-control study. Cases were 244 patients with one or more adenomas who underwent colonoscopy at the North Carolina Memorial Hospital between May 1983 and August 1985. Controls were 281 patients without adenomas. Overall, cholecystectomy was found in 11.9% of cases and 10.3% of controls. White women with adenomas, however, were more likely to have had previous cholecystectomy than controls [odds ratio (OR) 2.5, 95% confidence interval (CI) 1.1-5.6]. Although women with adenomas were older and heavier than controls, the elevated odds ratio persisted after adjustment for these factors (OR 1.8; 95% CI 0.8-4.2). No association was observed for men or for nonwhite women. Cholecystectomy may predispose to colon adenomas and to colon cancer in some patients. Alternatively, common risk factors for gallstones, cholecystectomy, and colon cancer may explain the apparent risk of colon cancer or adenomas after cholecystectomy.

The increased risk of proximal colonic cancer after cholecystectomy.

In a retrospective case control review we determined the cholecystectomy frequency of 479 index cases of colonic carcinoma and 479 age, sex, and admission date matched controls. The frequency distribution patterns of cholecystectomy with reference to subsite specific cancer of the large bowel were determined. The cholecystectomy frequency in patients with proximal colonic cancer was higher than those in whom cancer was present in areas other than the proximal colon (12.3 per cent vs. 6.6 per cent, P less than 0.02). There was a gradient of previous cholecystectomy history from the proximal colon to the rectum. The overall frequency of previous cholecystectomy in the index cases was 8.1 per cent while that in the matched control was 5.4 per cent. The difference was not statistically significant. However, the cholecystectomy frequency of the proximal colonic cancer subgroup was significantly higher than its matched control group (12.3 per cent vs. 4.6 per cent, P less than 0.02). The difference was greater in females with proximal colonic cancer compared with their matched controls (14.3 per cent vs. 3.6 per cent, P less than 0.02). Our data supported the hypothesis that either (1) altered bile salt metabolism after cholecystectomy may increase colonic cancer formation, or (2) gallbladder disease and colonic cancer may share common etiologic factors.

Helicobacter pylori infection increases following cholecystectomy.

Cholecystectomy is frequently linked with duodenogastric reflux and gastritis but its effect on Helicobacter Pylori (H pylori) infection has not been examined. In a prospective study, twenty two patients with documented cholelithiasis underwent upper gastrointestinal endoscopy and biopsy and 24hr dual channel pH monitoring prior to cholecystectomy and again at 3-6 months post-operatively. The antral biopsies were histologically assessed for H pylori and gastritis and awarded an alkaline reflux score. The number of patients with H pylori infection increased from 7 (32%) preoperatively to 15 (68%) post-cholecystectomy (p < 0.05). Cholecystectomy was also associated with an increase in the incidence of gastritis from 7 to 15 (p < 0.05). The increase in H pylori infection rate occurred in association with an increase in the percentage time gastric pH > 4 in the supine position, from 9.6 (2.2) to 22.2 (4.8) percent, (p < 0.01). The median chemical gastritis score, however, did not change significantly following surgery [8(3-11) vs 7(3-11)]. Seven patients remained symptomatic following cholecystectomy all of whom were H pylori positive and had gastritis. H pylori can survive in the alkaline environment which follows cholecystectomy and may contribute to the post-cholecystectomy syndrome.

Combined low pressure pneumoperitoneum and intraperitoneal infusion of normal saline for reducing shoulder tip pain following laparoscopic cholecystectomy.

INTRODUCTION: Intraabdominal CO(2) gas after laparoscopic cholecystectomy causes postoperative shoulder-tip pain. Many methods of analgesia have been used to reduce this pain, including analgesic drugs, intraperitoneal local anesthetic, intraperitoneal saline, a gas drain, heated gas, low-pressure gas, and nitrous oxide pneumoperitoneum. The aim of this study was to evaluate the efficacy of combined low-pressure CO(2) pneumoperitoneum and intraperitoneal infusion of normal saline in reducing the incidence of postoperative shoulder-tip pain. METHODS: Altogether, 109 patients undergoing elective laparoscopic cholecystectomy were randomized prospectively into three groups. Patients in group A (n = 34) underwent laparoscopic cholecystectomy with 14 mmHg CO(2) pneumoperitoneum; patients in group B (n = 37) underwent laparoscopic cholecystectomy with 10 mmHg CO(2) pneumoperitoneum; and those in group C (n = 38) underwent laparoscopic cholecystectomy with 10 mmHg CO(2) pneumoperitoneum in addition to intraperitoneal normal saline infusion in the right hemidiaphragmatic area. Shoulder-tip pain was recorded on a verbal rating scale 2, 6, 12, 24, and 48 hours after operation. RESULTS: Twelve patients in group A (35.2 percent), six in group B (16.2 percent), and seven in group C (18.4 percent) complained of shoulder-tip pain. Hence, there was a significant decrease in the frequency of shoulder-tip pain in groups B and C in relation to group A, but there was no significant difference between groups B and C. The postoperative shoulder-tip pain scores were significantly reduced in group C at 6, 12, and 24 hours. The number of patients who required additional analgesics was also reduced in group C. CONCLUSIONS: Low-pressure CO(2) pneumoperitoneum reduces the number of patients complaining of shoulder-tip pain and the intensity of the pain after laparoscopic cholecystectomy. The addition of intraperitoneal normal saline infusion to low-pressure CO(2) pneumoperitoneum seems to reduce the intensity but not the frequency of shoulder-tip pain after laparoscopic cholecystectomy.

Two-port versus four-port laparoscopic cholecystectomy.

BACKGROUND: Two-port laparoscopic cholecystectomy has been reported to be safe and feasible. However, whether it offers any additional advantages remains controversial. This study reports a randomized trial that compared the clinical outcomes of two-port laparoscopic cholecystectomy versus conventional four-port laparoscopic cholecystectomy. METHODS: One hundred and twenty consecutive patients who underwent elective laparoscopic cholecystectomy were randomized to receive either the two-port or the four-port technique. All patients were blinded to the type of operation they underwent. Four surgical tapes were applied to standard four-port sites in both groups at the end of the operation. All dressings were kept intact until the first follow-up 1 week after surgery. Postoperative pain at the four sites was assessed on the first day after surgery using a 10-cm unscaled visual analog scale (VAS). Other outcome measures included analgesia requirements, length and difficulty of the operation, postoperative stay, and patient satisfaction score on surgery and scars. RESULTS: Demographic data were comparable for both groups. Patients in the two-port group had shorter mean operative time (54.6 +/- 24.7 min vs 66.9 +/- 33.1 min for the four-post group; p = 0.03) and less pain at individual subcostal port sites [mean score using 10-cm unscaled VAS: 1.5 vs 2.8 ( p = 0.01) at the midsubcostal port site and 1.3 vs 2.3 ( p = 0.02) at the lateral subcostal port site]. Overall pain score, analgesia requirements, hospital stay, and patient satisfaction score on surgery and scars were similar between the two groups. CONCLUSION: Two-port laparoscopic cholecystectomy resulted in less individual port-site pain and similar clinical outcomes but fewer surgical scars compared to four-port laparoscopic cholecystectomy. Thus, it can be recommended as a routine procedure in elective laparoscopic cholecystectomy.

Laparoscopic cholecystectomy in cirrhotic patients.

BACKGROUND: This study aimed to evaluate the safety of laparoscopic cholecystectomy for patients with cirrhosis. METHODS: The records of 22 laparoscopic cholecystectomies performed in patients with cirrhosis Child-Pugh A and B, from January 1995 to July 2001 were retrospectively reviewed. RESULTS: No deaths occurred. Conversion to open cholecystectomy was necessary in two cases. The average operative time was 115 min, which was significantly shorter than that for patients undergoing open cholecystectomy. None of the patients required blood transfusion. Intraoperative problems occurred in two patients who experienced liver bed bleeding. Postoperative morbidity occurred in 36% of the patients and included hemorrhage, wound complications, intraabdominal collections, and cardiopulmonary complications, but all were controlled. The patients were dismissed after an average of 4 days. CONCLUSION: The authors believe laparoscopic cholecystectomy can be performed safely in selected patients with cirrhosis Child-Pugh A and B who manifest indication for surgery. Laparoscopic cholecystectomy offers several advantages over open cholecystectomy: lower morbidity, shorter operative time, and reduced hospital stay.

Minilaparoscopic (needlescopic) cholecystectomy: a study of 1,011 cases.

BACKGROUND: The safety and feasibility of minilaparoscopic cholecystectomy has not been documented with a large patient sample. This study reports the results of 1,011 minilaparoscopic cholecystectomies performed in a single institution. METHODS: From November 1997 to May 2002, 1,023 consecutive patients underwent minilaparoscopic cholecystectomy at National Taiwan University Hospital, Taipei, Taiwan. Patients with clinical evidence of common bile duct stones (1 patient) and combined surgery for other purposes (11 patients) were excluded. The operative indication, total operative time, conversion rate, hospital stay, morbidity and mortality of 1,011 patients were reviewed and statistically analyzed. RESULTS: Minilaparoscopic cholecystectomy was performed in 1,009 of 1,011 patients (375 males and 636 female; mean age, 54.8 years; range 13-92 years). The total operative time was 68.8 +/- 31.9 min. The total hospital stay was 2.5 +/- 2 days. One patient (0.10%) underwent conversion to open cholecystectomy because of common hepatic duct laceration. One patient (0.10%) underwent conversion to standard laparoscopic cholecystectomy for control of cystic artery bleeding. Ten patients (0.99%) experienced major complications including intraabdominal abscess (1 patient), bile leakage (5 patients), major bile duct injury (2 patients), bowel injury (1 patient), and postoperative hemorrhage (1 patient). Eleven patients (1.09%) had minor complications including wound infection, incisional herniation, postoperative ileus, and acute urine retention. One patient (0.10%) with bleeding tendency succumbed to postoperative hemorrhage. CONCLUSIONS: Minilaparoscopic cholecystectomy is a technically demanding approach. Our results indicate that this procedure could be performed successfully and safely by experienced surgical teams.

A prospective study of bile leaks after laparoscopic cholecystectomy.

Since laparoscopic cholecystectomy rapidly became the gold standard, there is an increased morbidity of 1% to 3% for clinically significant bile leaks with this procedure, as compared with open cholecystectomy (<1%). The identification of subclinical bile leaks using cholescintigraphy occurs in the range from 31.4% to 40% after elective open cholecystectomy. At this writing, no studies exist that document the rate of subclinical bile leaks after elective laparoscopic cholecystectomy. In this study, 71 patients were evaluated using cholescintigraphy after elective laparoscopic cholecystectomy. This study represents the first prospective look at the rate of subclinical bile leaks after laparoscopic cholecystectomy in elective cases, and the findings show an overall incidence of 7.3%, as compared with historical reports of 30% to 44% for open cholecystectomy.

Laparoscopic cholecystectomy in pregnancy. A report of 6 cases and review of the literature.

BACKGROUND: Although pregnancy was initially considered an absolute contraindication to laparoscopic cholecystectomy, there have been several case reports of successful laparoscopic cholecystectomy in pregnant patients in the literature over the past 4 years. We report our experience with six patients managed successfully with laparoscopic cholecystectomy during pregnancy. METHODS: More than 1,300 laparoscopic cholecystectomies were performed by the Norfolk Surgical Group between May 1991 and June 1994. Six of these patients (approximately 0.5%) were operated on during pregnancy. We reviewed the management and operative technique used in these patients compared to our standard approach. The available literature was reviewed to identify any other factors which might be helpful in the management of these patients. RESULTS: In this series we were able to perform laparoscopic cholecystectomy successfully in all six patients in whom it was attempted, with an overall course similar to that of nonpregnant patients. There were no significant complications to the patient or the fetus. All six patients have delivered healthy children and continue to do well. DISCUSSION: With the addition of our 6 patients, there have been 32 successful laparoscopic cholecystectomies during pregnancy reported in the English literature. We feel laparoscopic cholecystectomy can be performed safely in pregnant patients and should be considered in any patient who presents with symptomatic cholelithiasis during pregnancy.

Changes in bile salt composition after cholecystectomy and ileal resection.

The effect of ileal resection and cholecystectomy on bile salt metabolism was studied in female prairie dogs 4 weeks after either a sham laparotomy, cholecystectomy, ileal resection, or cholecystectomy and ileal resection. Bile was collected from a common bile duct cannula at hourly intervals for 12 hours. Pool sizes and synthetic rates of primary and secondary bile salts were determined from washout curves. Cholate, chenodeoxycholate, deoxycholate, and lithocholate levels were determined by gas chromatography from pooled collections of bile. After cholecystectomy and ileal resection, the pool sizes of primary and secondary bile salts were significantly reduced to amounts that were much less than the pool sizes after either procedure alone. Primary bile salt synthesis was significantly increased after combined cholecystectomy and ileal resection, to the same degree as cholecystectomy alone. After the combined procedures, there was a decrease in the proportion of cholate in hepatic bile associated with an increase in chenodeoxycholate, deoxycholate, and lithocholate levels. The data suggest that after the loss of both ileum and gallbladder the bile salt pool sizes are drastically reduced, the synthesis of primary bile salts is increased, and the proportion of secondary bile salts is increased. Cholecystectomy should be avoided, if possible, in patients with ileal resection in order to conserve the bile salt pool and prevent severe fat malabsorption.

Laparoscopic cholecystectomy.

Laparoscopic cholecystectomy is a newly developed technique for removing the gallbladder. Its future is very promising and this operation will probably become the preferred method of cholecystectomy for most patients. However, the limitations of laparoscopic cholecystectomy should be realized and great care must be taken to avoid technical complications. If laparoscopic cholecystectomy is associated with a much higher incidence of injuries to the bile duct than is traditional open cholecystectomy, its promise of decreasing pain, disability, and costs to patients undergoing cholecystectomy will be unfulfilled. The practicing general surgeon should learn laparoscopic techniques, since much of the future of abdominal surgery will ultimately reside in applying "less invasive" methods to perform standard operations. When embarking on a new procedure such as laparoscopic cholecystectomy, it is imperative that the surgeon remember the basis of his or her craft, primum non nocere.
