[Laparoscopic cholecystectomy. Initial experiences and results in 278 patients].

Of 467 cholecystectomies (performed between 13. 6. 1990 and 12. 9. 1991) 278 were done by laparoscopy (196 women, 82 men; mean age 53 [18-86] years). Contraindications to a laparoscopic procedure were acute cholecystitis, severe chronic cholecystitis with adhesions, abnormal clotting and suspected gallbladder carcinoma. In 31 patients (11.1%) the initial laparoscopic cholecystectomy was continued as a conventional cholecystectomy, usually because of unclear conditions in severe chronic cholecystitis. Mean duration of hospital stay was 6.3 days for the laparoscopic procedure compared with 11.5 days for the conventional one. Complications occurred in four patients (in 12 with the conventional method): one occlusion (by clip) of the common bile duct, one bile leak, one bleeding and one pneumothorax, requiring re-operation in three patients. There were no deaths (compared with two in the conventional group). Assuming correct indications, laparoscopic cholecystectomy is a sparing method for the treatment of cholecystolithiasis.

Role of cholecystectomy in preventing recurrent cholangitis.

BACKGROUND: Whether cholecystectomy should be performed after an episode of acute cholangitis is still unresolved. The purpose of this study was to analyze the role of elective cholecystectomy in preventing recurrent acute cholangitis in Asian patients. METHODS: Two hundred ten consecutive Asian patients with acute cholangitis caused by choledocholithiasis with coexisting cholelithiasis were studied prospectively. RESULTS: Forty-one patients (19.5%, Group 1) agreed to elective cholecystectomy whereas 169 patients (80.5%, Group 2) did not. Mean (+/- SEM) follow-up for Groups 1 and 2 were, respectively, 110.2 +/- 6.6 and 96.8 +/- 2.9 months. Endoscopic papillotomy was performed in 120 patients, 22 (53.7%) in Group 1 and 98 (58%) in Group 2. Recurrent acute cholangitis developed in 31 patients (14.8%), 9 in Group 1 and 22 in Group 2. There was no significant difference in the Kaplan-Meier estimates of the cumulative probability of occurrence of recurrent acute cholangitis between the 2 groups (p = 0.90). Recurrent acute cholangitis developed in 10 patients (8.3%) who underwent endoscopic papillotomy and in 21 (23.3%) patients who did not. There was a significant difference in the Kaplan-Meier estimates of the cumulative probability of occurrence of recurrent acute cholangitis between the patients with endoscopic papillotomy versus those without endoscopic papillotomy (p = 0.001). CONCLUSION: Cholecystectomy did not prevent recurrent acute cholangitis in Asian patients. In these patients, early endoscopic papillotomy lowered the frequency of recurrent acute cholangitis.

Recovery after uncomplicated laparoscopic cholecystectomy.

BACKGROUND: After laparoscopic cholecystectomy, the duration of convalescence is 2 to 3 weeks with an unclear pathogenesis. This study was undertaken to analyze postoperative recovery after uncomplicated elective laparoscopic cholecystectomy. METHODS: Twenty-four consecutive unselected employed patients were followed up prospectively from 1 week before to 1 week after outpatient laparoscopic cholecystectomy. Daily computerized monitoring of physical motor activity and sleep duration and night sleep fragmentation (actigraphy), subjective sleep quality, pulmonary function, pain, and fatigue were registered. Treadmill exercise performance (preoperatively and at postoperative days 2 and 8) and nocturnal pulse oximetry at the patients' homes (preoperatively and postoperative nights 1-3) were completed. RESULTS: Median age was 41 years (range, 21-56). Compared with preoperatively, levels of physical motor activity, fatigue, and pain scores were normalized 2 days after operation. Subjective sleep quality was significantly worsened on the first postoperative night, and sleep duration was significantly increased on the first 2 postoperative nights. There were no significant perioperative changes in actigraphy night sleep fragmentation, incidence of self-reported awakenings or nightmares/distressing dreams, exercise performance, or nocturnal oxygenation. Pulmonary peak flow measurements were normalized the day after operation. CONCLUSION: After uncomplicated outpatient laparoscopic cholecystectomy, there is no pathophysiologic basis for recommending a postoperative convalescence of more than 2 to 3 days in otherwise healthy younger patients.

Hydro-Jet-assisted laparoscopic cholecystectomy: a prospective randomized clinical study.

BACKGROUND: A new dissection technique with high-pressure water stream (Hydro-Jet) has recently been applied for selective dissection during various surgical procedures. The aim of this study was to compare Hydro-Jet with the conventional technique for laparoscopic cholecystectomy. METHODS: Eighty patients were randomized to undergo laparoscopic cholecystectomy with standard (n = 40) or Hydro-Jet-assisted (n = 40) dissection techniques. The rates of intraoperative complications, including blood loss and injury to the adjacent organs, were compared between the groups. The versatility of this technique and the features of surgical dissection were also evaluated and compared. RESULTS: Laparoscopic cholecystectomy was successfully completed in all subjects. The mean operative times were 78 minutes (range, 52-120 minutes) and 81 minutes (range, 45-135 minutes) for Hydro-Jet versus conventional dissection, respectively (P = not significant). Complications included gallbladder perforation in 15% and 30% (P <.1) and liver laceration in 0% and 10% (P <.04) with Hydro-Jet and conventional techniques, respectively. Increased hemorrhage from the gallbladder bed that necessitated fulguration occurred in 12 patients with the conventional technique as compared with none in the Hydro-Jet group (P <.001). Hydro-Jet resulted in a selective dissection of connective tissue preserving blood vessels and the cystic duct. The continuous water flow allowed a clear view for the operator, and the dissection was performed in a relatively bloodless field. The ease of blunt dissection with the bent-tip dissector represents another advantage. CONCLUSION: This study shows that Hydro-Jet dissection represents an excellent alternative to the conventional technique for laparoscopic cholecystectomy. The improved anatomic dissection combined with an almost bloodless operating field as the result of continuous water flow decreased the rate of dissection-related complications.

Effects of cholecystectomy on gastric emptying and myoelectrical activity in man.

To investigate the effects of cholecystectomy on gastric motor function, 13 patients with symptomatic gallstones were studied before and 8-12 months after surgery. Twelve healthy subjects entered the study as control group. The cutaneous electrogastrography and ultrasound examination of gastric emptying were simultaneously performed at pre- and post-prandial states. The dominant gastric frequency and its coefficient of variation were not affected by surgery. After cholecystectomy, an increase in normal 3 cpm wave percentage and a decrease in power ratio were found (P < 0.05 and P < 0.01, respectively). Gastric emptying recorded after cholecystectomy was faster than before surgery (306.9 +/- 15.9 min vs 336.9 +/- 11.8 min, respectively; P < 0.05). Such changes were associated with the relief of symptoms, and the comparison between patients and controls showed a normalization of the gastric electrical activity and gastric emptying after surgery. In conclusion, in symptomatic patients, gallstones are associated with motor dysfunctions, and cholecystectomy seems to induce a normalization of gastrointestinal motility.

False aneurysm of the hepatic artery after laparoscopic cholecystectomy.

PURPOSE: A rare complication of laparoscopic cholecystectomy is defined: iatrogenic injuries to hepatic artery system which may evolve to pseudoaneurysms in the late postoperative period. This rare phenomenon may be overlooked and pose a challenge to surgeons. MATERIAL AND METHODS: We will describe three cases with iatrogenic pseudoaneurysms after laparoscopic cholecystectomy. The onset of symptoms and the course of the disease was not uniform. Diagnosis was made after a considerable delay. In the first case, a small, uncomplicated extrahepatic pseudoaneurysm was successfully treated with coil embolization. The second patient who had an intrahepatic pseudoaneurysm with multiple injuries to the common bile duct and portal vein, did not survive despite surgical and endovascular interventions. In the latter, surgical treatment for a large pseudoaneurysm that had ruptured into the liver parenchyma was successfully conducted. Review of the literature reveals fifty-four more cholecystectomy-related pseudoaneurysms. The site of injury was the right hepatic artery in 61% of the cases and the presenting symptom was upper gastrointestinal bleeding (haemobilia) in two-third of the patients. Embolization was performed in 82% of the cases, and surgery was undertaken in the remaining 18%. CONCLUSION: Pseudoaneurysm is an uncommon complication of laparoscopic cholecystectomy. Prompt attention is necessary since the lesion has a high risk of rupture. Embolization is the first line of treatment and surgery is reserved for more complex injuries and cases with life-threatening rupture of the aneurysm.

Persistent dyspepsia after laparoscopic cholecystectomy. The influence of psychological factors.

BACKGROUND: Many patients with gallstone disease continue to report gastrointestinal symptoms after cholecystectomy, but the predictive value of preoperative factors is not well understood. We aimed to investigate whether psychological symptoms can be associated with poor outcome after cholecystectomy in patients with gallstones and dyspepsia. METHODS: A sample of 52 consecutive patients with uncomplicated gallstone disease and dyspepsia (conceived in a broader sense to include symptoms of the whole digestive tract) were assessed for psychological (revised 90-item Hopkins Symptom Checklist) and gastrointestinal symptoms (Gastrointestinal Symptom Rating Scale). One year after laparoscopic cholecystectomy, patients rated their gastrointestinal symptoms and were divided into improved and unimproved on the basis of the change in symptoms. RESULTS: Twenty-one (40.4%) patients did not improve after surgery. Improved and unimproved patients did not differ in terms of sex, age, education or illness duration. Unimproved patients showed significantly higher psychological and dyspeptic symptoms than improved patients before surgery. Logistic regression showed that psychological factors were significantly associated with unimprovement after surgery. CONCLUSIONS: Patients with gallstone disease and dyspeptic symptoms are unlikely to improve 1 year after surgery if they show psychological distress before surgery. Psychological symptoms were strongly associated with poor post-cholecystectomy outcome, thus highlighting the clinical relevance of joint assessment of psychological and gastrointestinal symptoms before surgery.

From acute to chronic pain after laparoscopic cholecystectomy: a prospective follow-up analysis.

OBJECTIVE: The pathogenesis and risk of chronic pain after cholecystectomy are unknown. In this prospective study of 150 consecutive patients undergoing laparoscopic cholecystectomy, the preoperative clinical data, cold pressor test, state of neuroticism and early postoperative pain intensity were assessed. MATERIAL AND METHODS: Follow-up questionnaires were sent to all patients 1 year after surgery. Patients with moderate/severe chronic pain were interviewed and invited to participate in a structured examination programme. RESULTS: The questionnaire response rate was 100%. Twenty patients reported moderate or severe chronic pain. The 1-year in-office interview revealed that two patients without chronic pain had misinterpreted the questionnaire. Sixteen patients were enrolled for the examination programme. Demonstrable pathology explained the aetiology of chronic pain in 8 patients (5%); another 8 patients with moderate (n=6) or severe (n=2) chronic pain were without pathological findings. In total, 132 patients had no chronic pain. Chronic pain patients suffered significantly more intense acute postoperative pain compared with those without chronic pain (p < or =0.05). The incidence of chronic pain patients was higher in the group of patients with intense acute postoperative pain than in patients with low acute postoperative pain (p = 0.030-0.063). Development of chronic pain was not statistically related to a preoperative cold pressor nociceptive stimulus, preoperative state of neuroticism or to any other variables examined. CONCLUSIONS: The risk of significant chronic pain after laparoscopic cholecystectomy for symptomatic cholecystolithiasis is low but was significantly associated with the intensity of acute postoperative pain. Patients should be carefully examined to exclude somatic causes of chronic pain after laparoscopic cholecystectomy.

Pain and dyspepsia after elective and acute cholecystectomy.

BACKGROUND: Postcholecystectomy pain occurs in 20-30%. The main cause of this pain remains unclear. Whether the underlying gallbladder disease influences the outcome after cholecystectomy is not fully established. METHODS: A multicenter questionnaire study comparing the occurrence of abdominal pain and dyspepsia 5-10 years after cholecystectomy in 345 (222 women, 123 men) patients cholecystectomized for acute cholecystitis and in a control group of 296 (213 women, 83 men) patients cholecystectomized for uncomplicated symptomatic gallbladder stones. RESULTS: Of 641 questionnaires, 534 (83%) were completed. Complaints of abdominal pain and dyspepsia were found with similar frequencies in the acute cholecystitis and gallstone groups. Women had abdominal pain more often than men (42% versus 29%) (P = 0.01). Although more than one-third complained of abdominal pain after cholecystectomy, 93% had improved or were cured. CONCLUSION: The outcome after cholecystectomy seems to be independent of the underlying gallbladder disease (acute cholecystitis or elective operations for gallstones).

Preoperative prediction model of outcome after cholecystectomy for symptomatic gallstones.

BACKGROUND: After cholecystectomy for symptomatic gallstone disease 20%-30% of the patients continue to have abdominal pain. The aim of this study was to investigate whether preoperative variables could predict the symptomatic outcome after cholecystectomy. METHODS: One hundred and two patients were referred to elective cholecystectomy in a prospective study. Median age was 45 years; range, 20-81 years. A preoperative questionnaire on pain, symptoms, and history was completed, and the questions on pain and symptoms were repeated 1 year postoperatively. Preoperative cholescintigraphy and sonography evaluated gallbladder motility, gallstones, and gallbladder volume. Preoperative variables in patients with or without postcholecystectomy pain were compared statistically, and significant variables were combined in a logistic regression model to predict the postoperative outcome. RESULTS: Eighty patients completed all questionnaires. Twenty-one patients continued to have abdominal pain after the operation. Patients with pain 1 year after cholecystectomy were characterized by the preoperative presence of a high dyspepsia score, 'irritating' abdominal pain, and an introverted personality and by the absence of 'agonizing' pain and of symptoms coinciding with pain (P < 0.000001). In a constructed logistic regression model 15 of 18 predicted patients had postoperative pain (PVpos = 0.83). Of 62 patients predicted as having no pain postoperatively, 56 were pain-free (PVneg = 0.90). Overall accuracy was 89%. CONCLUSION: From this prospective study a model based on preoperative symptoms was developed to predict postcholecystectomy pain. Since intrastudy reclassification may give too optimistic results, the model should be validated in future studies.

Mortality after open cholecystectomy in patients with cirrhosis of the liver: a population-based study in Denmark.

OBJECTIVE: To find out if patients with alcoholic cirrhosis are at greater risk of dying within 30 days of cholecystectomy than patients with non-alcoholic cirrhosis or normal controls. DESIGN: Population-based study. SETTING: Hospitals, Denmark. SUBJECTS: 23103 patients with liver cirrhosis recorded in the Danish National Registry during the period 1977-94, of whom 110 had an open cholecystectomy; a random sample of 1204 patients without cirrhosis taken from all patients who had a cholecystectomy during the study period. MAIN OUTCOME MEASURE: Risk of mortality. RESULTS: In the group with alcoholic cirrhosis the 30-day mortality was 7.7% and for the controls it was 0.9%. In patients with alcoholic cirrhosis the relative risk of death within 30 days was 11.5 (95% confidence interval 2.8 to 47.4) compared with controls, whereas that for patients with non-alcoholic cirrhosis was 1.1 (95% CI 0.1 to 9.8) compared with controls. CONCLUSION: Patients with alcoholic cirrhosis have an 11-fold increased risk of postoperative mortality after undergoing cholecystectomy.

Antimicrobial prophylaxis with ceftriaxone in laparoscopic cholecystectomy: a 7-year clinical experience involving 3,603 patients.

This study is one of the first in the literature with the aim of assessing the effectiveness of antimicrobial prophylaxis with a single preoperative dose of long-acting ceftriaxone in a retrospective analysis of 3,603 patients undergoing laparoscopic cholecystectomy. All patients who underwent laparoscopic cholecystectomy between October 1990 and December 1997 were reviewed. Antimicrobial prophylaxis with a single dose of ceftriaxone (1 g) was given intravenously at the induction of anesthesia. Patients were closely monitored for infections until 4 weeks after surgery. Postoperative infections occurred in 44 of the 3,603 patients undergoing laparoscopic cholecystectomy, with an infection rate of 1.22%. The infectious complications mainly comprised wound infections (n=13) but also included intra-abdominal abscesses (n=3), pneumonia (n=9), urinary tract infections (n=3) and other infections (n=16). The results of this retrospective and non-randomized study, show that a single-shot regimen containing ceftriaxone may be a cost-effective measure in preventing postoperative infections in patients undergoing laparoscopic cholecystectomy.

Laparoscopic cholecystectomy: fundus-down approach.

BACKGROUND AND PURPOSE: Laparoscopic cholecystectomy (LC) is the primary treatment of gallstone disease. Although refinements have made it safer, bile duct injury remains more common than with the open approach. The major difference in these techniques is that open cholecystectomy approaches the gallbladder from the fundus downward, whereas conventional laparoscopic cholecystectomy proceeds in the reverse direction. A handful of fundus-down techniques appear in the literature. The use of special instruments or port sites is common. We present a technique that is safe and utilizes instruments familiar to the surgeon performing conventional LC. PATIENTS AND METHODS: Fifty consecutive LCs were included in the study. The variables monitored were age, comorbidities, postoperative diagnosis, pathologic diagnosis, length of operation, hospital length of stay, and complications. RESULTS: The average operating time for chronic cholecystitis was 1 hour, and the average time for acute cholecystitis was less than 2 hours. Except for one early case of bleeding, in which the procedure was completed using the familiar conventional method, no complications and no unusual technical difficulties were encountered. There were no differences between conventional and fundus-down LC with regard to time and complications. CONCLUSIONS: This technique is safe and has several benefits: (1) standard trocar sites that offer the surgeon flexibility in the approach; (2) the ability to resect as much cystic duct as desired; and (3) utilization of standard instruments familiar to the surgeon, thus avoiding costly special instruments. The approach may offer the benefit of reducing the rate of common bile duct injury to that of open cholecystectomy.

Spilled gallstones after laparoscopic cholecystectomy.

Spilled gallstones have emerged as a new issue in the era of laparoscopic cholecystectomy. We treated a 77-year-old woman who underwent laparoscopic cholecystectomy. Subsequently, a right flank abscess developed. During the cholecystectomy, the gallbladder was perforated and stones were spilled. After a failed attempt to drain the abscess percutaneously, the patient required open drainage, which revealed retained gallstones in the right flank. The abscess resolved, although the patient continued to have intermittent drainage without evidence of sepsis. Review of the literature revealed 127 cases of spilled gallstones, of which 44.1% presented with intraperitoneal abscess, 18.1% with abdominal wall abscess, 11.8% with thoracic abscess, 10.2% with retroperitoneal abscess, and the rest with various clinical pictures. In case of gallstone spillage during laparoscopic cholecystectomy, every effort should be made to locate and retrieve the stones.

Laparoscopic cholecystectomy: retrospective comparative evaluation of titanium versus absorbable clips.

We present a retrospective study of the use of titanium and absorbable clips during laparoscopic cholecystectomy. The aim was to determine any differences in outcome and costs. From January 1999 to February 2002, 690 patients who had successfully undergone a laparoscopic cholecystectomy were reviewed. According to the type of clip, we retrospectively identified two groups of patients: 199 in whom the surgeons had used absorbable clips (absorbable clip group, ACG) and 491 in whom the surgeons had used titanium nonabsorbable clips (titanium clip group, TCG). Data about demographics, operation, results, complications, and follow-up were collected and matched in the two groups. Demographics, concomitant surgery, and the American Society of Anesthesiologists (ASA) status were comparable between the two groups. Although the proportions of cases requiring urgent operation, intraoperative cholangiography, use of a fourth trocar, and use of drainage suction were similar, the difficulty score of the operation was lower (6.3 vs. 7.0, P =.03) and the operative time was shorter (44 vs. 61 minutes, P <.0001) in the ACG than in the TCG. Complications, hospital stay, and long-term results were satisfactory and comparable between the two groups. No correlation was found between clip type and the incidence of biliary tree injuries, bleeding, wound infection, or readmission. The cost of the two types of clips varied slightly (90 euros for each procedure). Despite the fact that absorbable clips are theoretically less likely to cause complications than metallic ones, we were not able to demonstrate any clinical advantage during laparoscopic cholecystectomy in this retrospective study. Furthermore, the results suggest that absorbable clips are preferred when the cholecystectomy presents fewer difficulties.

Bupivacaine instillation into gallbladder bed after laparoscopic cholecystectomy: does it decrease shoulder pain?

BACKGROUND: Shoulder pain is common after laparoscopic cholecystectomy (60.5%) and can delay return to normal activities. The cause is unclear but may involve referral of pain from the traumatized area. PATIENTS AND METHODS: A total of 75 patients with chronic cholecystitis who underwent laparoscopic cholecystectomy were randomized into two groups. Group I (37 patients) had 10 mL of 0.25 % bupivacaine instilled into the gallbladder bed and Calot's triangle area at the end of cholecystectomy. Group II (38 patients) served as controls and had no bupivacaine instillation. Postoperative shoulder pain was evaluated. RESULTS: Six patients in Group I developed shoulder pain (16%) compared with 23 patients in Group II (60.5%). The difference was statistically significant (P = 0.0002). CONCLUSION: The raw area of the removed organ is at least partially responsible for shoulder pain after laparoscopic cholecystectomy. Local bupivacaine is effective in reducing such pain.

Outpatient laparoscopic cholecystectomy: experience of a nonovernight surgicenter.

From April 1994 to September 1998, a total of 66 laparoscopic cholecystectomies were performed at the same-day freestanding Surgicenter of the Yankton Medical Clinic. All patients (ages 15 to 62 years; 91% women) were discharged the same day, and no patient required hospitalization despite two conversions to open cholecystectomy. Cholangiofluoroscopies were completed in 70% of the patients. Pathologic evaluation showed chronic cholecystitis in all patients except one, who also had acute disease. No patient was lost to follow-up, and 98% responded that they "would do it again." These results confirm the safety of laparoscopic cholecystectomy in selected patients in a low- and controlled-cost environment of a freestanding surgical facility. Interestingly, Medicare does not allow facility reimbursement for cholecystectomy in any nonovernight outpatient surgery center in South Dakota.

Preoperative risk factors for common bile duct stones: defining the patient at high risk in the laparoscopic cholecystectomy era.

BACKGROUND: Common bile duct stones (CBDS) are present in 3-20% of patients with cholelithiasis. Intraoperative cholangiography has high sensitivity in detecting CBDS but its routine use is associated with increased costs and operating room time. The aim of our study was to define an accurate and simple model for the prediction of CBDS using preoperative variables. METHODS: The study consisted of a retrospective analysis followed by a prospective study. Multivariate analysis of the retrospective data was used to create a predictive model for the presence of concurrent CBDS in patients undergoing cholecystectomy. The predictive model was then validated in a prospective series of 160 patients undergoing laparoscopic cholecystectomy. RESULTS: Among the 19 potentially predictive variables for CBDS, only four were found to be statistically significant and independent: X1-alkaline phosphatase levels (UI/L); X2-number of gallbladder stones; X3-total serum bilirubin (mg/dL); and X4-CBD diameter (mm). Using these four variables, the multivariate analysis created the equation: score = 0.002 x X1 + 0.485 x X2 + 0.232 x X3 + 0.220 x X4 - 4.167 to define the risk of CBDS in each patient. The predictive model, tested prospectively in 160 patients undergoing laparoscopic cholecystectomy (LC), showed an elevated index of correlation (r = 0.75) among the predicted and the observed frequencies (chi2 = 126.6; P < 0.0001). The predictive model sensitivity and specificity were 92.9% and 99.3%, respectively. CONCLUSIONS: In patients undergoing cholecystectomy, accurate prediction of the risk for concurrent CBDS can be achieved using four preoperative variables. The use of this predictive model can contribute to reducing the number of unnecessary common bile duct explorations.
