Clinical characteristics of remote Zeus robot-assisted laparoscopic cholecystectomy: a report of 40 cases.

AIM: To summarize the performing essentials and analyze the characteristics of remote Zeus robot-assisted laparoscopic cholecystectomy. METHODS: Robot-assisted laparoscopic cholecystectomy was performed in 40 patients between May 2004 and July 2005. The operating procedures and a variety of clinical parameters were recorded and analyzed. RESULTS: Forty laparoscopic cholecystectomy procedures were successfully completed with Zeus robotic system. And there were no post-operative complications. Total operating time, system setup time and performing time were 100.3 +/- 18.5 min, 27.7 +/- 8.8 min and 65.6 +/- 18.3 min, respectively. The blood loss and post-operative hospital stay were 30.6 +/- 10.2 mL and 2.8 +/- 0.8 d, respectively. Camera clearing times and time used for operative field adjustment were 1.1+/- 1.0 min and 2.0 +/- 0.8 min, respectively. The operative error was 7.5%. CONCLUSION: Robot-assisted laparoscopic cholecystectomy following the principles of laparoscopic operation has specific performing essentials. It preserves the benefits of minimally invasive surgery and offers enhanced ability of controlling operation field, precise and stable operative manipulations.

Laparoscopic cholecystectomy: a report from a single center.

AIM: To review and evaluate our experience in laparoscopic cholecystectomy. METHODS: A retrospective analysis was performed on data collected during a 13-year period (1992-2005) from 1220 patients who underwent laparoscopic cholecystectomy. RESULTS: Mortality rate was 0%. The overall morbidity rate was 5.08% (n = 62), with the most serious complications arising from injuries to the biliary tree and the cystic artery. In 23 (1.88%) cases, cholecystectomy could not be completed laparoscopically and the operation was converted to an open procedure. Though the patients were scheduled as day-surgery cases, the average duration of hospital stay was 2.29 d, as the complicated cases with prolonged hospital stay were included in the calculation. CONCLUSION: Laparoscopic cholecystectomy is a safe, minimally invasive technique with favorable results for the patient.

A comparison of the incidence of nausea after laparoscopic cholecystectomy and diagnostic laparoscopy.

Thirty-four patients undergoing gynecologic diagnostic laparoscopy and 30 patients undergoing laparoscopic cholecystectomies were followed prospectively for nausea and vomiting 24 hours postoperatively. Diagnostic laparoscopy patients had a significantly higher incidence of nausea and vomiting than laparoscopic cholecystectomy patients with similar anesthetic techniques, duration of surgery, and population parameters. All patients had their stomach contents suctioned after induction. While both procedures involve bowel manipulation, patient position and organ manipulation differ: diagnostic laparoscopy involves the Trendelenburg position and laparoscopic cholecystectomy involves the reverse Trendelenburg; diagnostic laparoscopy involves the uterus, ovaries, and fallopian tubes while laparoscopic cholecystectomy involves mainly the gall-bladder and its appendages. These factors may contribute to the differences found in this study.

[Bile duct injuries after a laparoscopic cholecystectomy].

Eight years after the introduction of laparoscopic cholecystectomy a decrease of the incidence of bile duct injuries is reported in the literature. The incidence of a bile duct injury after laparoscopic cholecystectomy is now slightly higher than after open cholecystectomy. A minority of these injuries are detected during surgery. Most patients have a delayed identification of the bile duct injury, even after discharge from the hospital. An early diagnostic work-up with ultrasound and endoscopic retrograde cholangiopancreatography (ERCP) is mandatory in every patient with persisting symptoms (more than 48 hours) after laparoscopic cholecystectomy. Still, one-third of the patients are subjected to a 'diagnostic' exploratory laparotomy without preoperative visualization of the biliary tract by ERCP or percutaneous transhepatic cholangiography. Minor lesions are mostly treated successfully by endoscopy with a stent. After transection of the bile duct surgical reconstruction by a hepaticojejunostomy has to be performed. A delayed elective reconstruction was associated with fewer complications than acute repair under suboptimal circumstances such as local inflammatory changes and bile leakage.

Laparoscopic cholecystectomy during pregnancy: three case reports.

OBJECTIVE: The purpose of this presentation is to investigate the effects and feasibility of laparoscopic cholecystectomy during pregnancy. METHODS AND PROCEDURES: We present three pregnant patients who underwent a laparoscopic cholecystectomy for biliary colic during the early second and early third trimester of pregnancy. We also reviewed the literature regarding this topic. RESULTS: All three pregnant patients had uneventful hospital courses after their procedures and delivered full-term babies without complications. Laparoscopic cholecystectomy during the first trimester of pregnancy is contraindicated due to the ongoing fetal organogenesis and during the third trimester is not technically feasible due to the large uterine size. CONCLUSIONS: We conclude that laparoscopic cholecystectomy during the second and very early third trimester of pregnancy is safe and feasible.

Ideal pain relief following laparoscopic cholecystectomy.

In a previous report the effectiveness of intraperitoneal bupivacaine in reducing pain following laparoscopic cholecystectomy was demonstrated. Other methods of pain relief are commonly used but none has been compared following laparoscopic cholecystectomy. In two further studies we have compared the analgesic effect of intraperitoneal bupivacaine against wound infiltration with bupivacaine, and against intraperitoneal bupivacaine with the addition of a non-steroidal anti-inflammatory drug (NSAID) in patients undergoing laparoscopic cholecystectomy. Two consecutive studies were performed. In the first, patients in group 1 were given 20 ml of 0.25% bupivacaine into the peritoneal cavity; patients in group 2 were given 20 ml of 0.25% bupivacaine injected into the trocar wounds. In the second study, patients in group 1 were given 20 ml of 0.25% bupivacaine into the peritoneal cavity; patients in group 2 were given 20 ml of 0.25% bupivacaine into the peritoneal cavity and a diclofenac suppository (100 mg) one hour before surgery. Postoperative pain was assessed with a visual analogue pain scale. There was no difference in pain scores in the two groups in either study. Intraperitoneal bupivacaine is as effective as wound infiltration. The addition of an NSAID makes no difference in the reduction of postoperative pain following laparoscopic cholecystectomy.

[Malpractice in laparoscopic cholecystectomy. Results of cases recently considered by the Expert Commission].

The Expert Commission for medical malpractice which is part of the Medical Chamber of Nordrhein received about 60 applications in connection with laparoscopic cholecystectomy; as of August 1998 5 complaints were let off and 11 of them are still being considered. So far 44 complaints have been considered and in 25 of them medical malpractice has been established. The medical malpractice detected laparoscopic cholecystectomy cases were mainly bile duct injuries of which 13 required a biliodigestive anastomosis for reconstruction, four cases required and end-to-end anastomosis and in one case a T-tube drainage was needed. The youngest one of these patients was 21 years old, the oldest one was 61 years old. Four times the bile duct injury was not considered as malpractice, because it could be intraoperatively made out and immediately treated. Trocar injuries were twice a cause for malpractice and once it was not. Each of the following cases was also recognized as a malpractice. One lost gallstone one dislocated Roedersnare, one electric injury, one delayed reintervention and one insufficient information. The following cases were decided as non-malpractice: in two cases a slipped clip, in five cases subhepatical hematoma/abscess, in three cases a secondary bleeding, once a lesion of the splenic capsule and finally a running sore with subsequent incisional hernia. Three courses of treatment with consequence of death also contained mistakes: one electric injury of the bowel, one bile duct lesion and one information rebuke. The bile duct injury is the most considerable risk for laparoscopic cholecystectomy and implies also a high risk for the future health. The experienced surgeon distinguishes himself by the fact that he is right about the situation and converts sooner that later to conventional cholecystectomy if there's any doubt. In open surgery the principle is applied that structures may be only divided when they are clearly identified. The same goes even on a wider scale for laparoscopic surgery too.

Short and long term outcome after laparoscopic cholecystectomy.

BACKGROUND: As an audit of patients undergoing laparoscopic cholecystectomy this study not only reports the short term results, but attempted to assess the long term effect of the operation on the symptom profiles of the patients. METHODS: Three hundred unselected consecutive patients underwent elective laparoscopic cholecystectomy from January 1991 to July 1994. Short term outcome was analysed by reviewing patient files for operation details, postoperative morbidity, complications, and gallbladder histology. Long term (median 2 years) outcome was evaluated by a detailed postal questionnaire. Symptomatic benefit ratios (BR) accruing from the laparoscopic removal of the gallbladder were calculated. RESULTS: Twelve operations (4.0%) were converted to open surgery and were excluded from long term outcome analyses. Median operation time was 93 (range 40-245) minutes. There were no deaths. Overall morbidity was 13 %. Median postoperative hospital stay was 2 days (range 1-18 days) and median time-off work 15 days (range 2-49 days). The overall response rate to the questionnaire was 87%. Only one of the 261 patients (0.4%) suffered from recurrent common bile duct stones so far. As shown by the benefit ratios the symptoms most effectively relieved by laparoscopic cholecystectomy were biliary pain (0.97), nausea (0.95), vomiting (0.96) and jaundice (0.94). Most patients with diarrhoea (0.70) and heartburn (0.66) felt relief. Constipation (0.39) and food intolerance (0.57) were unaffected. Most patients (90%) felt that the operation-initiating symptom had disappeared and 98 percent of the patients considered that they had obtained overall symptomatic improvement by the operation. CONCLUSIONS: Laparoscopic cholecystectomy appears to be a safe and effective way of treating the most common symptoms related to gallstone disease.

[Laparoscopic cholecystectomy in children].

OBJECTIVE: Retrospective evaluation of laparoscopic cholecystectomy in children. The authors deal with the asset of the method in child surgery and emphasize the differences of treatment of cholelithiasis in children by a laparoscopic approach. METHOD: During 1994 to 1998 the authors made 54 laparoscopic cholecystectomies in children 5 to 18 years old (mean age 14.0 years). The indication for surgery was in 48 patients cholecystolithiasis and in six instances confirmed chronic cholecystitis without concrements. Four times cholecystolithiasis associated with congenital haemorrhagic disease was found. The majority of patients, i.e. 51 (94.4%), was operated during the quiescent stage of the disease. RESULTS: In the group of operated children no serious peroperative and postoperative complications were recorded. Twice concrements from the bile duct were removed by papillosphincterotomy in cholecystocholedocholithiasis after previous laparoscopic cholecystectomy. CONCLUSION: In child surgery laparoscopic cholecystectomy is a less frequent operation than in adults. However, it is also in children an effective and safe method with all advantages of mini-invasive operations.

Combined laparoscopic splenectomy and cholecystectomy for the treatment of hereditary spherocytosis: is it safe and effective?

Hereditary spherocytosis is the most common red blood cell membrane disorder and often is associated with hemolytic crisis and premature cholelithiasis. Splenectomy is the only effective therapy for this disorder and often it is performed in combination with cholecystectomy. Conventional surgery requires a wide upper abdominal incision for correct exposure of the gallbladder and spleen. Laparoscopic cholecystectomy and splenectomy have been performed safely worldwide. We report our experience with seven patients (one male and six female, average age 12 years) who underwent combined laparoscopic splenectomy and cholecystectomy for hereditary spherocytosis. The patient was placed in supine position and the procedure performed with a five-trocar technique. Cholecystectomy was performed first, then splenectomy was achieved and the spleen removed by morcellation into a retrieval bag (five cases) or via a 4- to 5-cm left subcostal incision (two cases). No patient required conversion to open technique or blood transfusion. The mean blood loss was 162 mL, mean operative time 207 minutes, mean spleen size 14.5 cm, and median postoperative hospital stay 4 days. No perioperative mortality or major complications occurred in our series. After a median follow-up of 18 months all patients showed sharp hematologic improvement. Despite the small number of cases, we consider the combined laparoscopic approach safe and effective for the treatment of hereditary spherocytosis.

Anomalous insertion of the right hepatic duct into the cystic duct: report of a case diagnosed before laparoscopic cholecystectomy.

Although an aberrant hepatic duct entering the cystic duct is not especially rare, the main right hepatic duct entering the cystic duct is extremely rare, with only six cases reported thus far. All of the reported patients underwent open cholecystectomy, during which one patient received a bile duct injury. The anomaly was unsuspected preoperatively in all of these cases. We report an additional patient with this anomaly, the first such case diagnosed before laparoscopic cholecystectomy using direct cholangiography. Cholangiography may be mandatory whenever biliary anomalies are suspected during laparoscopic cholecystectomy. As the right hepatic duct entering the cystic duct can lead to ductal injury, this anomaly should be kept in mind when performing laparoscopic cholecystectomy.

Postmenopausal estrogen replacement therapy and increased rates of cholecystectomy and appendectomy.

BACKGROUND: Several studies have indicated that estrogen may prime inflammatory and nociceptive pathways, leading to symptoms that mimic cholecystitis. We set out to confirm the relation between recent estrogen use and cholecystectomy in postmenopausal women and to test the novel hypothesis that a similar relation exists for appendectomy. METHODS: We developed a retrospective cohort using prescribing and surgical procedure information from health administrative databases for approximately 800,000 female residents of Ontario who were over 65 years of age between July 1, 1993, and Mar. 31, 1998. We compared the incidence of cholecystectomy and appendectomy among women recently prescribed estrogen replacement therapy, levothyroxine and dihydropyridine calcium-channel antagonists (DCCA) using age-adjusted Cox proportional hazards models. Patients were followed for a mean of 540 (standard deviation [SD] 449) days. RESULTS: Compared with women taking DCCA, those who had recently begun taking estrogen were significantly more likely to undergo cholecystectomy (age-adjusted risk ratio [aRR] 1.9, 95% confidence interval [CI] 1.6-2.2) and appendectomy (aRR 1.8, 95% CI 1.1-3.0). No significant difference in either outcome measure was found between the levothyroxine users and the DCCA users. INTERPRETATION: This study identifies an increased risk of cholecystectomy and appendectomy among postmenopausal women who have recently begun estrogen replacement therapy.

[Laparoscopic cholecystectomy. Our experience].

BACKGROUND AND AIMS: The authors analyse their first two years of experience regarding the use of laparoscopic cholecystectomy and report the results of this series and their observations. METHODS: A total of approximately 200 cholecystectomies have been performed using a laparoscopic technique at S. Paolo Hospital in Naples (Department of Surgery; Head: Prof. R.A. Caliendo) since October 1996. Initially patients were rigorously selected in accordance with international criteria. At present, after the good results obtained, the real contraindications to laparoscopic cholecystectomy are considered to be: a) the patient's refusal; b) general conditions that do not allow the use of general anesthesia in surgery. RESULTS: None of these 200 patients was converted to open surgery, although six complications occurred: four of these were cases of bleeding in which it was decided to choose a carefully monitored wait-and-see approach. Mean postoperative hospitalisation was two days. No major postoperative complications were observed and it was not necessary to keep any patient for more than five days. CONCLUSIONS: On the basis of this experience, the authors underline the value of laparoscopic surgery versus open cholecystectomy (reduced morbidity, shorter hospitalisation with marked social and economic advantages). Furthermore, the authors emphasise that, when laparoscopy is first introduced, it is important for the same operating team always to be present in order to ensure a good learning curve and increasing familiarity with the technique.

[Comparison of the results of laparoscopic cholecystectomy preformed in the usual way and with a lesser number of trocars].

Laparoscopic surgery is a part of the minimally invasive surgery. Its aim is to make on operation as valuable as the open one, or even more, with a smaller invasion or injury of the body. With the instruments improvement the operation would be possible without any remarkable organism injury. On the other hand, modifications of the operation techniques lead to progress. European technique of laparoscopic cholecystectomy using four trocars has changed. Procedures are performed with one trocar less. Two groups of two hundred patients each have undergone laparoscopic cholecystectomy. The operation in the first group was performed using four, and in the second group using three trocars. The aim of the investigation was to compare these two methods of laparoscopic cholecystectomy. The results analysis showed that laparoscopic cholecystectomy using three trocars did not cause either a higher complication rate, prolonged average operation time or longer duration of hospitalisation. The analgesics consumption was lower, sick-leaves were shorter, with smaller total costs, and cosmetic effect was better.

Laparoscopic cholecystectomy in patients with bilharzial portal hypertension.

OBJECTIVE: The purpose of this study was to evaluate the results of laparoscopic cholecystectomy in patients with bilharzial portal hypertension. METHODS: Patients who had gallstones and bilharzia had ultrasonographic assessment of peri-portal fibrosis, endoscopy, hemagglutination and rectal snip. Operating time, blood loss, hospital stay, time of return to work and operative mortality were recorded. Follow-up was two weeks, six weeks and six months after discharge. RESULTS: Twenty-five out of 450 patients, who had laparoscopic cholecystectomy, suffered from bilharzial portal hypertension. Ten patients had grade 1 varices, 10 had grade 2 varices, and 5 had grade 3 esophageal varices. All patients had varying degrees of peri-portal fibrosis as shown by ultrasound. Rectal snip showed schistosoma mansoni in 5 patients, and a hemagglutination test was positive in all. Two patients had conversion to open cholecystectomy. Mean operating time was 1 hour and 15 minutes. Average blood loss was 50 cc. Mean hospital stay for 23 patients was 48 hours. Average time of return to work was 2 weeks in 23 patients and 6 weeks in the 2 patients who had conversion. Twenty-two patients benefited from the operation. There was no mortality in this series. CONCLUSIONS: Laparoscopic cholecystectomy in patients with bilharzial portal hypertension is feasible and has low morbidity.

Selective intraoperative cholangiography during laparoscopic cholecystectomy: how selective?

The necessity for intraoperative cholangiography during laparoscopic cholecystectomy has been debated for some time. Numerous retrospective studies favor selective intraoperative cholangiography. Surgeons in favor of the selective policy differ in their personal selective criteria. The aim of this prospective study was to evaluate whether intraoperative cholangiography can be safely omitted during laparoscopic cholecystectomy on all patients who fit a standard set of criteria: normal liver function tests, common bile duct diameter less than 10 mm, and no history of gallstone pancreatitis or jaundice. We undertook a prospective study on 155 consecutive patients treated in a county teaching hospital with symptomatic gallbladder disease who met the above standard set of criteria. One hundred and fifty-five patients meeting these criteria underwent laparoscopic cholecystectomy during a 2-year period from February 1996 through February 1998. Data analyzed included patient history, laboratory and ultrasound findings, operative results, postoperative stay, and intraoperative and postoperative complications. The patients were followed by periodic interviews, physical examination, liver function tests, and/or biliary ultrasound for up to 3 1/2 years with a mean follow-up of 26 months for retained common bile duct stones. Intraoperative cholangiography was performed in only one of the 155 patients studied to confirm common bile duct injury. There were four postoperative complications (2.6%) and one common bile injury (0.6%). Postoperative stay averaged one day. No patients, by history, biliary ultrasound, liver function tests or endoscopy, were found to have retained common bile duct stones during the follow-up period. Our study shows that intraoperative cholangiography is not necessary for patients undergoing laparoscopic cholecystectomy who have normal liver functions tests, common bile duct diameter less than 10 mm, and no history of gallstone pancreatitis or jaundice.

Does cholecystectomy affect antral mucosa? Endoscopic, histopathologic and DNA flow cytometric study.

BACKGROUND/AIMS: Although cholecystectomy is still the "gold standard" for treatment of gallstones, this operation may be followed by gastric disorders. The aim of this study is to detect the effects of cholecystectomy on gastric antral mucosa. METHODOLOGY: This prospective study has been carried out on 46 patients (20 M & 26 F) with mean age 41.7 +/- 0.2 years for whom simple cholecystectomy for gallstones was decided. Prior to the operation and 1 year after, patients were subjected to the following: clinical assessment, upper gastrointestinal endoscopy, histopathology of antral mucosa, detection of H. pylori and DNA flow cytometry. RESULTS: There was an increase in the number of patients presenting suggestive symptoms of reflux gastritis: patients experiencing epigastric pain increased from 8 (17.4%) to 11 (23.39%) patients, nausea increased from 6 (13%) to 12 (26.1%) patients and bilious vomiting increased from 3 (6.5%) to 11 (23.9%) patients. Mild antral gastritis increased from 20 (43.5%) to 27 (58.7%) patients. Antral gastritis and antral erosions were detected only after the operation in 8 (17.4%) and 2 (4.3%) patients, respectively. The incidence of active chronic superficial gastritis decreased from 23 (50%) to 13 (28.2%) patients while the inactive form increased from 15 (32.6%) to 23 (50%) patients. Chronic atrophic gastritis, intestinal metaplasia and dysplasia were only detected postoperatively in 2 (4.3%) patients each. There was a decrease in the incidence of H. pylori infection from 32 (69.6) to 19 (41.3%) patients. DNA aneuploid pattern increased from 1 (2.2%) to 4 (8.7%) patients and there was a significant increase of DNA index from 1.01 (+/- 0.03) to 1.03 (+/- 0.05) (P < 0.005). CONCLUSIONS: Changes in clinical, endoscopic and histopathologic findings suggest that cholecystectomy may affect gastric antral mucosa due to duodenogastric reflux. Flow cytometry may be used as an objective method for detection and evaluation of postcholecystectomy reflux gastritis.

Intraperitoneal bupivacaine does not attenuate pain following laparoscopic cholecystectomy.

BACKGROUND: Laparoscopic cholecystectomy is characterized by a short hospital stay. Hence, pain control on the day of surgery is increasingly important. The aim of this study was to evaluate the effect of intraperitoneal bupivacaine on pain relief following laparoscopic cholecystectomy. METHODS: Sixty patients undergoing elective laparoscopic cholecystectomy were prospectively randomized into 2 groups. Following removal of the gallbladder, group A received 100 mg of bupivacaine in 50 cc of saline, installed into the gallbladder bed and right subphrenic space. Group B received saline without bupivacaine. Pain was assessed using a visual/analog scale at fixed-time intervals. RESULTS: No significant difference occurred in the average pain levels between the groups at 1, 2, 4, and 14 hours postsurgery. The average analgesic requirement was lower in the bupivacaine group, but this did not reach statistical significance. CONCLUSION: Application of intraperitoneal bupivacaine did not attenuate pain following laparoscopic cholecystectomy, and no role exists for its routine use.
