Laparoscopic cholecystectomy: the state of the art. A report on 700 consecutive cases.

Born in secret in 1987, developed in an atmosphere of skepticism and even hostility throughout 1988, the laparoscopic cholecystectomy triumphed in 1989-90 and caused a veritable revolution in the world of general surgery. The 700 consecutive cases that we report here reflect the spirit of these various periods. From prudently restrictive, our indications widened to include 90% of all patients with gallbladder lithiasis. Sclero-atrophic gallbladders constitute the greatest challenge for endoscopic maneuvers. This group of patients should be treated by the most experienced operators only. The figures for mortality (0.1%) and complications (3%) are very comparable and even better than those for traditional cholecystectomy. The quality of recovery is infinitely better; there is absence of pain, a short period of hospitalization, return to normal physical activity within 10 days, rapid return to work, and total preservation of the abdominal muscles for participation in sports activities. All these advantages are assets of the laparoscopic cholecystectomy which are not available to the 6% of patients for whom an intra-operative conversion to open surgery is necessary. These patients recover within the conditions of a traditional cholecystectomy which are far from being poor. The large multicenter studies, such as those carried out in France and Belgium recently involving 3,708 patients, arrive at identical conclusions. The laparoscopic cholecystectomy is on its way to becoming the gold standard of treatment for gallbladder lithiasis. It is the first successful step towards surgical techniques of the 21st century which will be carried out inside the musculo-cutaneous envelope of the unopened human body.

Emergency versus elective cholecystectomy in acute cholecystitis.

The present study was carried out at the Department of Surgery, All India Institute of Medical Sciences Hospital, New Delhi, between January 1982 and October 1984. Clinical diagnosis of acute cholecystitis was confirmed by ultrasound scanning or Tc99m labelled HIDA Scan. Group I (n=24) comprised patients who underwent emergency cholecystectomy while Group II (n=23) comprised patients who were managed conservatively, and had an elective cholecystectomy performed 6-12 weeks later. There was no mortality or wound infection in either group. The incidence of other complications was 8.3 per cent and 8.6 per cent in Groups I and II, respectively. Emergency cholecystectomy (Group I) reduced the total hospital stay of a patient by approximately 70 per cent and post cholecystectomy syndrome was seen in Group II patients only. We thus recommend emergency or early cholecystectomy during the acute stage of cholecystitis, as it is safe, effective and economical, provided it is done by an experienced surgeon.

Negative correlation between cholecystectomy and the subsequent development of large bowel carcinoma in a low-risk Japanese population.

The incidence of previous cholecystectomy in a series of 541 patients with colorectal cancer and 1832 patients with stomach cancer was studied. Five patients (0.92 percent) with colorectal cancer and eight (0.44 percent) with stomach cancer had undergone previous cholecystectomy. To avoid biases in the two groups of patients, 416 pairs of patients, comparable in sex, age, and time of admission for cancer treatment, were matched from each group to compare the number of patients who had undergone previous cholecystectomy. Within these matched pairs, three patients with colorectal cancer and two with stomach cancer had histories of cholecystectomy. Hence, no substantial difference was noted between the two groups. In a follow-up study of 461 patients who had undergone cholecystectomy for gallstones, large bowel carcinoma and stomach carcinoma developed in one and six patients, respectively, during an observation period of four to 36 years. The ratio of patients with large bowel cancer to those with stomach cancer observed in this survey was almost equal to the value estimated for the population of Tottori Prefecture, where the majority of the patients reside. The incidence of large bowel carcinoma is not increased among cholecystectomized patients in a low-risk Japanese population.

Relationship between cholecystectomy and colonic cancer in low-risk Japanese population. A preliminary study.

The relationship between colonic cancer and previous cholecystectomy was investigated in 90 Japanese patients treated surgically for colonic cancer during the period of 1971 to 1980. The patients were in an area where the inhabitants are considered to be at low risk for colonic cancer. The patients were matched for sex and age with other patients having gastric cancer or other digestive organ diseases. The results showed that previous cholecystectomy was prevalent, but the difference was not statistically significant, in the group of colonic cancer patients, compared with the groups of rectal cancer patients and matched controls. A positive association between the proximal colonic cancer and previous cholecystectomy, and between distal colonic cancer and asymptomatic gallstones found concomitantly with the cancer, was noted in the present study. To clarify the relationship between colonic cancer, and cholecystectomy and gallstones, further study of a large number of colonic cancer patients and a prospective study of the incidence of colonic cancer after cholecystectomy are proposed.

Timing of laparoscopic cholecystectomy in acute cholecystitis.

BACKGROUND: Laparoscopic cholecystectomy is associated with an increased conversion rate in acute cholecystitis. AIM: To review the operative management of symptomatic cholelithiasis with particular reference to conversion rates and morbidity for laparoscopic cholecystectomy for acute cholecystitis. METHODS: Patients undergoing cholecystectomy between January 1994 and December 1998 were recruited. Demographic details, diagnosis, duration of symptoms, treatment, outcome, post-operative stay and complications were recorded. RESULTS: Complete data were available on 482 patients (84%). Laparoscopic cholecystectomy was attempted in 120 of 132 patients (91%) with acute cholecystitis and 329 of 350 patients (94%) with non-acute gallbladder disease. Conversion rates were 27% (33/120) and 6.7% (22/329) for acute and non-acute gallbladder disease, respectively (p < 0.001 chi2 test). Relating the interval from onset of symptoms to surgery, conversion rates for acute cholecystitis were: < 3 days, 5/17 (29%); 4 to 42 days, 14/59 (23%) and > 42 days, 14/44 (31%). There were three bile duct injuries, two in the delayed (> 45 days) acute group and one in the non-acute group. CONCLUSION: Early laparoscopic cholecystectomy is the treatment of choice for acute cholecystitis, but is associated with a high conversion rate independent of the timing of surgery.

Cholecystectomy and oesophageal pathology: is there a link?

Symptoms persist in a significant proportion of patients following cholecystectomy, some of which may have an oesophageal aetiology. The oesophagus has not previously been studied in this patient group. In this study all patients who had undergone cholecystectomy over a four year period were invited for review and symptoms were documented. Oesophageal function was examined and compared with normal controls. Patients were subdivided into symptomatic and asymptomatic subgroups and their findings compared. Symptoms were present in 53 percent of the postcholecystectomy group. The mean (sem) DeMeester acid score was higher in the post-cholecystectomy group -20.6 (3.6) than in controls -6.7 (0.9) (p = 0.01). The incidence of oesophagitis and gastritis were also increased in this group. There was a trend towards increased reflux and oesophagitis in the symptomatic compared with the asymptomatic subgroup. Other findings confined to the post-cholecystectomy group included nutcracker oesophagus in 4 and irritable bowel syndrome in 3. It is suggested that cholecystectomy may be associated with changes in oesophageal function which, in turn, may be associated with persistent symptoms.

Respiratory mechanics and arterial blood gases during and after laparoscopic cholecystectomy.

PURPOSE: The purpose of this study was to assess the effects of increased intra-abdominal pressure due to CO2 insufflation on the mechanical characteristics of the respiratory system and arterial blood gases during and after laparoscopic cholecystectomy. METHODS: Respiratory mechanics and arterial blood gases were examined in 12 patients undergoing laparoscopic cholecystectomy with CO2 insufflation. Respiratory mechanics were continuously monitored with in-line spirometry. In the recovery room, PaCO2 was measured in this group at 30 min and compared with PaCO2s in 23 patients who had undergone open cholecystectomy retrospectively, to evaluate the effects of insufflation on CO2 elimination. RESULTS: Minute ventilation was decreased by about 500 ml.min-1 during abdominal insufflation. Dynamic lung compliance decreased from 49.6 +/- 4.7 to 30.7 +/- 2.3 (mean +/- SEM) ml.cmH2O-1 with abdominal insufflation (P < 0.005), and returned to 45.1 +/- 3.1 after the release of pneumoperitoneum. Peak inspiratory pressure increased from 15.9 +/- 0.9 to 18.9 +/- 1.0 cmH2O with abdominal insufflation (P < 0.05). Arterial blood gas determinations indicated a decrease in arterial pH, with CO2 retention during insufflation and in the recovery room (P < 0.05). PaCO2 of the laparoscopic patients was higher than that of the open patients in the recovery room. CONCLUSION: The results indicate that respiratory acidosis was caused during CO2 insufflation for laparoscopic cholecystectomy, that was due to (1) decreased compliance, (2) increased CO2 load and (3) insufficient ventilation. Accumulated CO2 during laparoscopic cholecystectomy increased PaCO2 level in the recovery room.

Contemporary outcomes of ambulatory laparoscopic cholecystectomy in a major teaching hospital.

Ambulatory laparoscopic cholecystectomy is an established practice in our institution, with an experience of more than 800 cases. The present study is conducted to evaluate the contemporary outcomes of day-case laparoscopic cholecystectomy in the setting of a major teaching hospital. A retrospective analysis of 200 patients who underwent ambulatory laparoscopic cholecystectomies was performed to evaluate the postoperative morbidity, unplanned admission, and readmission rates. Causes for unanticipated admission and readmission were analyzed. Uneventful recovery was attained in 185 (92.5%) patients. The mean length of the operation was 56 +/- 20 (SD) minutes. There was no hospital mortality, and no patient required conversion to open cholecystectomy. Nine patients were admitted overnight after operation because of nausea and vomiting (n = 3), pain (n = 2), urinary retention (n = 2), medical observation n = 1), and patient's preference (n = 1), leading to an unanticipated admission rate of 4.5%. Six patients required readmission because of postoperative complications (n = 4) and abdominal pain (n = 2), giving a readmission rate of 3%. The overall postoperative morbidity rate was 3% (n = 6), including retained stones n = 4), bile leakage (n = 1), and hepatic subcapsular hematoma (n = 1). Ambulatory laparoscopic cholecystectomy is a safe practice in appropriately selected patients. Postoperative nausea and vomiting was the commonest reason for unanticipated admission after operation, and retained stones was the most frequent postoperative morbidity necessitating readmission.

Is male gender a risk factor for bile duct injury during laparoscopic cholecystectomy?

BACKGROUND: Since its introduction in the late 1980s laparoscopic cholecystectomy has become the treatment of choice for gallstone disease. Unfortunately, the rate of iatrogenic biliary duct injuries (BDIs) has at least doubled after the adoption of the laparoscopic method. Population-based studies reporting the distribution of laparoscopic BDI patients according to gender and the severity of the BDI are mostly lacking. The purpose of the present study was to analyze the BDIs sustained during laparoscopic cholecystectomy in and around Turku University Central Hospital, with a special reference to the distribution of patients according to gender and the severity of the BDI. PATIENTS AND METHODS: A total of 3,736 laparoscopic cholecystectomies (2,627 female patients, 1,109 male) was performed in and around Turku University Central Hospital from 1995 to 2002 (by the end of April). The number and severity of BDIs and the gender of BDI patients were recorded, and the risk of BDI during laparoscopic cholecystectomy was calculated for the total patient population and for both genders separately. RESULTS: The risk of BDI was 0.86% for the total patient population, 0.95% for female and 0.63% for male. The most conspicuous finding was that the female gender was predominant in the severe types of BDI. However, the risk of mild BDI seemed to be fairly equal in both genders. CONCLUSION: We conclude that female gender seems to be a risk factor for severe iatrogenic BDI during laparoscopic cholecystectomy.

Medium-term results after cholecystectomy in patients younger than 10 years.

BACKGROUND: Gallbladder stones are a well-known and widely studied problem in children. Hematological disorders are the most common diseases that can cause cholelithiasis. However, in the last few years, the proportion of children with idiopathic cholelithiasis has increased 50%. Herein, we present a prospective study on laparoscopic cholecystectomy in a selected group of patients aged < 10 years. METHODS: Fifty-eight patients aged < 10 years underwent laparoscopic cholecystectomy for stones in the period 1992-99. The female/male ratio was 1.5, the mean age was 8 years (range, 2-10), and the mean weight was 30 kg. In all patients, parenteral nutrition, fasting state, and prolonged use of antibiotics had been suspended for > or = 6 months, and conservative treatment had been tried for > or = 12 months in the absence of symptoms of stone migration. All the patients were followed up after surgery: clinically at 1,6,12, and 36 months and by ultrasound at 1, 12, and 36 months. Liver function and hematological tests were performed in case of symptoms or if hemolytic disorders were the cause of stones. RESULTS: The mean operative time was 63 min (range, 30-120) in children undergoing cholecystectomy alone and 150 min in children undergoing associated splenectomy. There were no major complications or reoperations. Minor complications included bleeding from accessory cystic artery (n = 3) and insufflation of the omentum (n = 2). One case was converted to an open procedure due to technical problems. All the children were followed up and no complications were observed. CONCLUSION: We consider the laparoscopic approach the gold standard for cholecystectomy in children. This procedure does not have a complication rate any higher than open cholecystectomy, and patient follow-up is as good as that of open surgery. Previous abdominal surgery is not a contraindication to laparoscopy.

Comparison of economic and environmental impacts between disposable and reusable instruments used for laparoscopic cholecystectomy.

BACKGROUND: The economic and environmental effects were compared between disposable and reusable instruments used for laparoscopic cholecystectomy. Special consideration was given to the processing of reusable instruments in the Miele G 7736 CD MCU washer disinfector and the resultant cost of sterilization. METHODS: The instruments frequently used in their disposable form were identified with the help of surgeons. Thus, of all the instruments used for laparoscopic cholecystectomy, the disposable and reusable versions of trocars, scissors, and Veress cannula were compared. RESULTS: For the case examined in this study, the performance of laparoscopic cholecystectomy with disposable instruments was 19 times more expensive that for reusable instruments. The higher cost of using disposable instruments is primarily attributable to the purchase price of the instruments. The processing of reusable instruments has little significance in terms of cost, whereas the cost for disposing of disposable instruments is the least significant factor. The number of laparoscopic cholecystectomies performed per year does not substantially influence cost. In the authors' opinion, assessment of the environmental consequences shows that reusable instruments are environmentally advantageous. CONCLUSIONS: Considering the upward pressure of costs in hospitals, disposable instruments should be used for laparoscopic cholecystectomy only if they offer clear advantages over reusable instruments.

Color Doppler ultrasound detection and classification of the tangential hepatic vein before laparoscopic cholecystectomy.

BACKGROUND: Unexpected fatal bleeding from the gallbladder bed during laparoscopic cholecystectomy is often associated with injury to the middle hepatic vein. This paper studies whether preoperative color Doppler ultrasound is effective in reducing the risk of injury. Also a venous classification is suggested. METHODS: Between June 1999 and February 2004, 2,146 patients undergoing laparoscopic cholecystectomy by standard method received preoperative color Doppler ultrasound examinations. The closest distance between the hepatic vein and the gallbladder was studied. Also, cases of liver cirrhosis, number of conversions to open cholecystectomy, intraoperative blood loss, operative time, complications, and hospital stay were recorded (group D). At the end of the study, we retrospectively reviewed the same parameter of another 2,146 patients who received laparoscopic cholecystectomy without preoperative color Doppler ultrasound between the period of March 1995 and June 1999 (group ND). RESULTS: In group D, 108 patients had cirrhosis. Four hundred and ninety-six patients (27 cases of cirrhosis) had a closest distance of 1 mm or less between the vein and the gallbladder. There were two conversions to open cholecystectomy, but none related to gallbladder bed bleeding. In group ND, there were five conversions, including four cases of gallbladder bed bleeding from the middle hepatic vein and one case of severe adhesion. The conversion rate was significantly higher. In group ND, the mean intraoperative blood loss in the cases of liver cirrhosis was significantly greater. Also, the operative time of patients with the closest vein and gallbladder distance of 1 mm or less in group D was significantly longer. CONCLUSIONS: Color Doppler ultrasound is an effective method for detecting the presence of potential bleeders. Although the operative time will be a bit longer, the operation can be done under meticulous care and complete preparation, so that the conversion rate and the risk of fatal hemorrhage can be reduced, especially in patients with liver cirrhosis.

Laparoscopic cholecystectomy in cirrhotic patients.

BACKGROUND: Due to unacceptable increases in intra- and postoperative complications and associated morbidity, cirrhosis of the liver is often considered to be a contraindication for laparoscopic cholecystectomy (LC). However, recent advances have now made it increasingly possible for experienced surgeons to perform LC on this high-risk population. The aim of this study was to evaluate the impact of the coagulopathy associated with cirrhosis on the performance and results of LC. We hypothesized that the factors leading to hemorrhage, rather than Child's classification, would drive operating time and resource utilization. METHODS: Between 1 July 1996 and 30 June 2003, 1,285 cholecystectomies were performed. Thirty one of these patients had evidence of cirrhosis at the time of operation. The 31 patients were divided into high, (low platelets, prolonged International Normalized Ratio) (n = 18), intermediate, (abnormal liver function tests, normal clotting) (n = 5), and low, (normal platelets, normal clotting, and normal liver function tests) (n = 8) surgical risk categories for further analysis. Based on the Child-Turcotte-Pugh (CTP) classification of cirrhosis, there were three grade C and 28 grade A or grade B patients. RESULTS: There were 24 LC, three of which were started laparoscopically and then converted to open, and four open cholecystectomies. Operating room time ranged from 79 to 450 min, with the extent of coagulopathy correlating with the length of time needed to achieve satisfactory hemostasis. Median length of stay postoperatively in the high-risk group was 2 days (range, 0-20). Nine of the cholecystectomies were performed on an outpatient basis. One patient received a liver transplantation 5 months post-LC. There were no operative deaths, bile duct injuries, or returns to the operating room for bleeding. Blood product usage correlated with preexisting coagulopathy. CONCLUSIONS: Currently, the classification of cirrhotic patients is normally done using the CTP score. However, preoperative platelet levels and INR more accurately predict the difficulty of cholecystectomy than CTP score, because intraoperative hemorrhage is the primary concern in these patients. This study demonstrates that preoperative degree of coagulopathy, and not Child's class, should guide the surgeon's approach and expectations when LC is performed in a cirrhotic patient.

Three-port microlaparoscopic cholecystectomy in 159 patients.

BACKGROUND: Laparoscopic cholecystectomy has undergone many refinements including reductions in port size and number. This study attempts to determine whether further reduction in port size from that previously reported by us can reduce postoperative pain without compromising the efficacy of the surgery. METHODS: In this study, 159 patients underwent laparoscopic cholecystectomy with three ports: one 5-mm umbilical port, one 3-mm subxiphoid port, and one 3-mm port in the right subcostal position. Data were collected prospectively for each patient on the duration of analgesic use, quantity of analgesic tablets consumed, postoperative pain, most painful incision, and days of recovery required before return to activity and work. These measures were compared with those collected from a group of 100 patients who had undergone laparoscopic cholecystectomy with three 5-mm ports in a previous study. RESULTS: Patients in the current study group required analgesics for a longer duration (4 vs 2.9 days; p = 0.001), used more analgesic tablets (10.7 vs 8.1; p = 0.007), and reported greater postoperative discomfort (5 vs 4.1; p = 0.016) as compared with all in the 5-mm port group. The 3-mm port group needed more days for recovery before leaving the house (2.9 vs 2.7; p = 0.504), but they returned to work earlier (5.1 vs 5.9; p = 0.065) than the group that had undergone cholecystectomy with three 5-mm ports, although there was not a significant difference between the groups. Operative time increased from 18.5 to 20.9 min (p = 0.054) in the group with two 3-mm ports. Five patients (3.1%) in the current group required enlargement of a port to complete the procedure, as compared with none in the comparison group. There was one complication (0.6%), as compared with two complications (2.0%) in the previous group. CONCLUSIONS: This study did not demonstrate a reduction in postoperative pain or a consistent improvement in recovery when the port size was reduced at the subcostal and subxiphoid positions. It did, however, show that ports could safely be reduced in size without a negative impact on the surgeon's ability to perform a cholecystectomy. Reducing port size can be a tool in the surgeon's armamentarium for use in the attempt to optimize cosmetic results.

Outcomes analysis of laparoscopic cholecystectomy in the extremely elderly.

BACKGROUND: A study was conducted to determine whether extremely elderly patients, age 80 years or older, were at higher risk for adverse outcomes from laparoscopic cholecystectomy than patients younger than 80 years. METHODS: Laparoscopic cholecystectomy was attempted in 421 patients age 65 years or older from 1989 through 1999. The patients were divided into two groups: group 1 (age 65-79 years; n = 351) and group 2 (age, 80-95 years; n = 70). A prospective database was analyzed for mean +/- standard deviation and using Student's t-test and chi-square analysis. RESULTS: Advanced age (group 2) was associated with a higher mean American Society of Anesthesiology (ASA) class (2.7 vs 2.3; p < 0.001) and a greater incidence of common bile duct stones (43% vs 26%; p < 0.01), as compared with those of younger age (group 1). Mean operative times in group 2 were 106 +/- 45 min as compared with 96 +/- 38 min in group 1, a difference that is not significant. The extremely elderly (group 2) had a four-fold higher rate of conversion to open cholecystectomy (16% vs 4%) and a longer mean postoperative hospital stay (2.1 vs 1.4 days). Grades 1 and 2 complications also were more common in group 2: grade 1: group 1, 8.8% vs group 2, 17% and grade 2: group 1, 4.3% vs group 2, 7.1% (p < 0.05). One patient in group 1 had a myocardial infarction 13 days postoperatively, and two deaths occurred in the extremely elderly group within 30 days postoperatively. CONCLUSIONS: Laparoscopic cholecystectomy in the extremely elderly is associated with more complications and a higher rate of conversion to open cholecystectomy than in elderly individuals younger than 80 years. The greater chance of encountering a severely inflamed or scarred gallbladder and common bile duct stones as well as increasing comorbidities likely account for these differences in outcome.

Sigmoid volvulus after laparoscopic cholecystectomy. An unusual complication.

Laparoscopic cholecystectomy has become the standard surgical technique for treating symptomatic gallbladder disease. Intestinal obstruction after laparoscopic cholecystectomy is unusual. We present the case of a 37-year-old man who underwent routine laparoscopic cholecystectomy for cholelithiasis using an American four-port technique. He was well 24 h postoperatively and was discharged. He presented 36 h later with clinical features of bowel obstruction. A sigmoid loop was seen on a plain abdominal radiograph. Laparotomy revealed distension of the large and small bowel to the level of the rectosigmoid junction and a sigmoid volvulus. This was reduced by releasing adhesions to lengthen the sigmoid mesentery. A primary sigmoid resection and anastomosis was not attempted due to luminal discrepancy and lack of bowel preparation. The patient underwent interval sigmoid colectomy 2 weeks later. A sigmoid volvulus following laparoscopic cholecystectomy has not been previously reported. It may be related to the induction of the pneumoperitoneum, combined with the lateral tilt of the table and a long redundant sigmoid colon. This case expands the range of potential complications associated with laparoscopic cholecystectomy and illustrates the need for continued vigilance after apparently routine procedures.

Robotic-assisted laparoscopic cholecystectomy.

We report a case of laparoscopic cholecystectomy that was performed using a robotic surgical system. A 70-year-old woman underwent laparoscopic robotic cholecystectomy ZEUS, the robotic system used in our study, has three interactive robotic arms fixed to the side of the operating table. The arms are controlled by the surgeon, who sits at a remote computer console. The surgeon's movements can be scaled down, and tremor is filtered out. The robotic-assisted laparoscopic cholecystectomy was completed in 42 min. The time to set up the robot was 22 mins. All of the surgically reproducible robotic maneuvers were performed without any particular difficulty. The robotic movements were stable, accurate, and reliable, as well as easy to control with precision. Our preliminary experience indicates that robotic laparoscopic cholecystectomy is safe and can be as fast as conventional laparoscopic cholecystectomy. However, further clinical applications of robotic surgery are needed to confirm this observation.

Initial results of a prospective trial of outpatient laparoscopic cholecystectomy.

BACKGROUND: Whether or not laparoscopic cholecystectomy may be performed safely as an outpatient procedure is controversial. In 1993, a protocol for outpatient laparoscopic cholecystectomy was instituted to determine the benefits and safety of discharging patients within several hours of surgery. METHODS: The initial 60 outpatient laparoscopic cholecystectomies performed by one surgeon in a hospital-based outpatient teaching facility between February 1993 to June 1996 were prospectively studied. RESULTS: Fifty-eight (97%) patients were discharged successfully after an average stay in the recovery room of 3 h. There were no deaths. Two patients required overnight observation and three patients required readmission. Two patients (3%) had cystic duct leak. The average hospital stay for all patients undergoing laparoscopic cholecystectomy at the institution (inpatient and outpatient) decreased from 3.2 to 1.5 days and the average hospital cost decreased from $7,800 to $4,600 during this period. CONCLUSION: Laparoscopic cholecystectomy in an outpatient setting is safe and cost-effective in healthy patients.
