Laparoscopic ultrasonography is a complement to cholangiography for the detection of choledocholithiasis at laparoscopic cholecystectomy.

BACKGROUND: Intraoperative cholangiography and laparoscopic ultrasonography are both used in the detection of common bile duct stones at laparoscopic cholecystectomy. The aim of this prospective study was to determine whether laparoscopic ultrasonography has an alternative or a complementary role with respect to cholangiography in achieving this end. METHODS: The biliary trees of 900 patients undergoing laparoscopic cholecystectomy were examined routinely by the two methods. The diagnostic power of each investigation and of the two techniques in combination was evaluated. The statistical non-random concordance between the two methods was also determined. RESULTS: Laparoscopic ultrasonography was performed in all 900 patients. Cholangiography was performed in 762 (85 per cent). The mean (range) duration was 9.8 (4-21) min for laparoscopic ultrasonography and 17.6 (7-42) min for cholangiography. For the detection of common bile duct stones, with a kappa coefficient of 0.57 (95 per cent confidence interval (c.i.) 0.43 to 0.71), the non-random concordance between the two methods was considered to be fair to good. The sensitivity of laparoscopic ultrasonography was 0.80 (95 per cent c.i. 0.65 to 0.91) and its specificity was 0.99 (95 per cent c.i. 0.98 to 1.00). The respective values for cholangiography were 0.75 (95 per cent c.i. 0.59 to 0.87) and 0.99 (95 per cent c.i. 0.98 to 1.00). The examinations combined had a sensitivity of 0.95 (95 per cent c.i. 0.86 to 0.99) and a specificity of 0.98 (95 per cent c.i. 0.96 to 1.00). CONCLUSION: Laparoscopic ultrasonography and intraoperative cholangiography are complementary, as the combination of both methods maximizes the intraoperative detection of choledocholithiasis.

[Quality of life one year after laparoscopic fundoplication is close to that of a control group: prospective study].

AIM OF THE STUDY: Prospective evaluation of the quality of life of patients after laparoscopic fundoplication for gastroesophageal reflux disease (GERD). PATIENTS AND METHODS: The quality of life of 30 consecutive patients who underwent laparoscopic fundoplication was evaluated using the GIQLI (gastrointestinal quality of life index) questionnaire, which included 36 items in five different areas: digestive symptoms, physical condition, emotional reaction, social integration and medical treatment. Seventeen men and 13 women (mean age: 50.2 +/- 17 years (32-68) were included with a follow-up of at least 1 year and with complete data available. The quality of life was evaluated before surgery, and at 1 month, 3 months, 6 months and 1 year after surgery with a 100% follow-up. Thirty healthy volunteers representing an identical population (with respect to age, sex, BMI, profession, smoking, etc.) anonymously filled in the same questionnaire. The pre- and postoperative GIQLI scores of patients operated for GERD were compared with the GIQLI score of the control group. RESULTS: Preoperatively, the GIQLI score (87 +/- 9.5) was much lower than that of the control group (123.4 +/- 13.6) (p < 0.001). This score significantly improved 3 months and 1 year after surgery and was comparable to that of the healthy population (115.3 +/- 9.6 vs 123.4 +/- 13.6 [ns]). Improvements were reported mainly with respect to digestive symptoms and physical condition. Social integration was slightly modified. CONCLUSION: The quality of life of patients after laparoscopic antireflux surgery was greatly improved and was close to the level expected in an healthy population. However, the study demonstrated the possible presence of postoperative functional digestive disorders, although these symptoms were not considered as being uncomfortable, since the level of satisfaction was 96.6% (n = 29).

Quality of life 2 years after laparoscopic total fundoplication: a prospective study.

This study was a prospective evaluation of the quality of life of 50 patients after laparoscopic total fundoplication surgery for gastroesophageal reflux disease. The quality of life of 50 consecutive patients who underwent laparoscopic total fundoplication was evaluated using the Gastrointestinal Quality of Life Index questionnaire, which included 36 items in five different areas: symptoms, physical well-being, psychologic well-being, social relationships, and effects of medical treatment. Twenty-seven men and 23 women with a mean age of 52.6 +/- 16 years (range, 31-68 years) with gastroesophageal reflux disease were treated by laparoscopic total fundoplication (Nissen-Rosetti) and were included in the study. The follow-up was at least 2 years after surgery. The quality of life was evaluated before the surgery and 1 month, 3 months, 6 months, 1 year, and 2 years after surgery with follow-up in 100% of the cases. A control group of 50 healthy volunteers representing an identical population to that of the patients operated on (with respect to age, sex, body mass index, profession, and smoking) anonymously completed the same questionnaire. The preoperative and postoperative Gastrointestinal Quality of Life Index questionnaire scores of patients who had laparoscopic total fundoplication were compared with the Gastrointestinal Quality of Life Index questionnaire scores of the control group. Before surgery, the Gastrointestinal Quality of Life Index questionnaire score (86.7 +/- 8.5) was much inferior to that of the control group (123.8 +/- 13.6) (P < 0.001). This score significantly improved 3 months after surgery and was comparable (not significant) to that of the healthy control population 3 months, 6 months, 1 year, and 2 years after surgery (119.3 +/- 7.8). Improvements were reported mainly with respect to gastrointestinal symptoms and physical well-being. Social relationships were not modified. The quality of life of patients after laparoscopic surgery for gastroesophageal reflux disease improved and was close to the level expected in a healthy individual.

Laparoscopic ultrasound of the liver.

OBJECTIVE: Despite recent advances in medical imaging, pre-operative evaluation of liver tumors, whether benign or malignant, is often lacking in accuracy and precision. With the development of surgical laparoscopy, the benefits of diagnostic laparoscopy have been combined with those of operative ultrasound. This article aims to describe the technique of laparoscopic ultrasound of the liver, and to define its applications and the role of its association with diagnostic laparoscopy in the localization and assessment for resectability of liver tumors. METHODS: After an initial visual inspection with the laparoscope, laparoscopic ultrasound is utilized to further examine the liver. This relies largely on recognition of branches of the portal vein and tributaries of the hepatic veins. During this procedure, the hepatic parenchyma is also examined. Minimal displacement of the transducer, using clockwise and anti-clockwise rotatory movements, allows a full exploration of the liver. RESULTS: The combination of visual with sonographic laparoscopy allows accurate localization of benign and malignant hepatic tumors, as well as ultrasound-guided biopsies of these. Laparoscopic ultrasound can detect small lesions previously unseen by pre-operative imaging techniques. The relationship of tumors to adjacent blood vessels can be defined. Portal vein thrombosis can be diagnosed. CONCLUSION: Curability and liver tumor resectability can be determined and the appropriate surgical treatment thus planned.

Two-stage laparoscopic management of generalized peritonitis due to perforated sigmoid diverticula: eighteen cases.

The classic treatment of generalized peritonitis due to perforation of sigmoid diverticula is based on the principle of a two-stage surgery with a temporary derivation of the colonic transit. This procedure is associated with a prohibitively high immediate and delayed morbidity, especially associated with the abdominal wound. The laparoscopic approach to this complication is less aggressive and allows a second-stage elective laparoscopic resection. Eighteen consecutive patients (ten women and eight men; average age, 53.7 years) underwent emergency laparoscopic treatment for generalized peritonitis due to perforated diverticula. Eight of these patients had previously had diverticulitis attacks. By peritoneal cavity exploration and full peritoneal lavage (average, 15 L), the infected sigmoid lesion was stuck with biologic glue. A drain was inserted at the site of the lesion and in some cases also in other abdominal zones. No colostomy was necessary. Antibiotic treatment was started at diagnosis and continued for a minimum of 7 days. There was no mortality. Morbidity was limited to three patients (two cases of lymphangitis and one of pulmonary disease). No patient had a wound abscess or residual deep collections. The mean hospitalization was 8 days. Fourteen patients underwent elective laparoscopic sigmoid resection with a delay of 3.5 months. One conversion to laparotomy was necessary. The laparoscopic treatment of generalized peritonitis due to perforated sigmoid diverticula is an interesting alternative to the traditional treatment. It is associated with a lower morbidity, a shorter postoperative hospital stay, and an improvement in the patient's quality of life, because colostomy is avoided. It is also associated with economic savings.

The use of diagnostic laparoscopy supported by laparoscopic ultrasonography in the assessment of pancreatic cancer.

BACKGROUND: Pancreatic resection with curative intent is possible in a select minority of patients with carcinomas of the pancreatic head. Diagnostic laparoscopy supported by laparoscopic ultrasonography combines the proven benefits of staging laparoscopy with high-resolution intraoperative ultrasound, thus allowing the surgeon to perform a detailed assessment of the pancreatic cancer. METHODS: In a prospective study of 26 patients with obstructive jaundice from a carcinoma of the head of the pancreas, the curative resectability of tumors was assessed by ultrasound (26 cases), computerized tomography (26 cases), endoscopic ultrasound (16 cases), and a combination of diagnostic laparoscopy and laparoscopic ultrasound (26 cases). RESULTS: The findings of ultrasound and computerized tomography were comparable: 50% of patients were excluded from curative resection. Endoscopic ultrasound provided precise information on the primary tumors. The accuracy of the combined diagnostic laparoscopy and laparoscopic ultrasound, when compared with ultrasound, computerized tomography, and endoscopic ultrasound, was better with respect to minute peritoneal or hepatic metastasis: 80.7% (or a further 30.7%) of patients did not qualify for curative resection. CONCLUSIONS: Diagnostic laparoscopy supported by laparoscopic ultrasonography enables detection of previously unsuspected metastases; thus, needless laparotomy can be avoided. It should therefore be considered the first step in any potentially curative surgical procedure.

[Systematic peroperative cholangiography during laparoscopic cholecystectomy].

STUDY AIM: The aim of this study was to assess the feasibility of routine intra operative cholangiography during laparoscopic cholecystectomy (LC) and to evaluate its impact in the detection of common bile duct stones or iatrogenic bile duct injuries. PATIENTS AND METHOD: From January 1991 to January 1999, 1,050 patients (mean age: 52.5 years) with symptomatic or complicated cholelithiasis were operated on laparoscopically. Intraoperative cholangiography was attempted in all patients before cholecystectomy, performed with an ureteral catheter (diameter: 5 F) introduced into the cystic duct under control of intensifier screen. In case of detection of common bile duct stones (CBDS) or bile duct injury, a surgical management was routinely attempted laparoscopically. RESULTS: Cholangiography was successfully performed in 840 cases (82.4%). The mean duration of this examination was 15 min (7-45). The success rate was significantly higher in patients with uncomplicated cholelithiasis (90.4%), compared to patients with acute cholecystitis (61.9%) (p = 0.01). The failure rate decreased with experience, falling from 23% for the first 100 attempts to 1% for the last 100. CBDS were identified in 62 patients (7.4%) in 18% of those with acute cholecystitis and 4.6% of those with uncomplicated cholelithiasis. In 21 cases (33%), there were no predictive factors to suggest CBDS. There were 8 false positive (0.9%). Among the 6 cases of bile duct injury observed in this series (0.57%), four patients had an intraoperative cholangiography and the injury was diagnosed peroperatively in two patients and immediately repaired. There was no postoperative death in this series. CONCLUSIONS: Routine intraoperative cholangiography appears to be the best method for the detection of common bile duct stones and improves prognosis of bile duct injuries when they are immediately detected and peroperatively repaired.

[Ultrasonographic laparoscopy of the liver].

SITUATION: In spite of recent progress in medical imagery, the findings of preoperative investigations of the liver are not always accurate and precise. Since the development of surgical laparoscopy, advantages of the laparoscopic examination are associated with advantages of laparoscopic ultrasonography. OBJECTIVE: The purpose of this work is to report the technique of staging laparoscopy with laparoscopic contact ultrasonography in the intraoperative assessment of patients with liver tumors, and to analyse its impact on the selection of patients for hepatic resection with curative intent. METHODS: The basic exploration follows at first portal branches and then hepatic veins. During the course of vascular exploration, the corresponding liver parenchyma is examined. A mobilization of the probe with clockwise or anticlockwise rotation movements allows full exploration of the liver. RESULTS: The association of laparoscopic examination and laparoscopic ultrasonography allows to localize with accuracy malignant and benign lesions and to perform ultrasound guided biopsy. Liver tumors not visible on preoperative imagery may be identified, relationships with adjacent vessels and presence of tumoral thrombi in major vascular structures may be assessed. Resectability of the liver tumors is at the best specified. CONCLUSION: Staging laparoscopy with laparoscopic ultrasonography improves selection of patients for liver resection and facilitates choice and performance of the most appropriate resection.

[Impact of learning and experience on the laparoscopic treatment of gastroesophageal reflux].

STUDY AIM: Laparoscopic treatment of gastroesophageal reflux disease (GERD) by partial (PF) or total (TF) fundoplication is the most appropriate surgical treatment after failure of medical treatment. The aim of this study was to compare the results of the same series in three consecutive periods in order to determine the effects of the learning curve and experience on the technique and outcome. PATIENTS AND METHODS: From January 1993 to January 1998, 150 patients (84 men and 66 women) with a mean age of 52.2 years (18 to 78) were included. Three groups of 49, 50 and 51 patients were chronologically defined. The comparison was established on the following criteria: the operative technique; the conversion rate; the mortality and morbidity rate; the duration of surgery and hospitalization and the results with short and medium follow-up. RESULTS: The three groups were comparable with respect to patients and GERD characteristics. One hundred and thirty two patients had a TF and 18 had a PF. Rossetti's type TF became the reference procedure (80.3% in group III) and closure of the diaphragmatic crura was performed systematically in group III (100%). The duration of surgery was significantly reduced between group I and the two other groups (138, 100, 80 min). The rate of conversion decreased from 10.2% to 4% and then 0%. The average duration of hospitalization decreased from 5.8 to 4.2 days (p = 0.01). There was no mortality and the morbidity rate decreased from 14.3% to 4% and then 0%. Seven cases of recurrence occurred (4.6%), 5 in group I (10.2%), 2 in group II (4%), and 0 in group III, (with a shorter follow-up). CONCLUSION: The effect of the learning curve has to be taken into account in the training of surgeons (within experienced departments, with "guidance" during initial interventions) and also in the evaluation of results, in order to allow a more accurate comparison between the different treatments for GERD.

[Effects of surgical education and training on the results of laparoscopic treatment of inguinal hernias].

STUDY AIM: The aim of this retrospective study was to compare two concurrent series of patients operated on for inguinal hernia with the same laparoscopic procedure, the first one in a teaching hospital with a number of trained surgeons and the second one in a private center with only one trained surgeon. PATIENTS AND METHOD: Five hundred and forty-one patients with 757 hernias were operated on over a period of six years by a totally pre-peritoneal laparoscopic approach. Two hundred and sixteen patients were operated on in a teaching hospital by 48 surgeons (six senior and 42 trainee surgeons; group I), 325 were operated on in a private center by one surgeon who had been trained in the same teaching hospital (group II). The two groups of patients and their hernias were comparable. The comparison was established on the following criteria: duration of operation, rate of conversion, length of hospitalization, morbidity and mortality rate, recurrence rate and costs. RESULTS: Operations performed by surgical trainees were associated with: (1) a mean operative time significantly (P = 0.01) longer for both unilateral (68 vs. 41 min) and bilateral (108 vs. 68 min) hernias. The operative time did not change in the teaching hospital and decreased with experience in private practice (from 62 to 25 min for unilateral hernias); (2) more frequent per-operative complications, particularly opening of the peritoneum (28% vs. 3%, P = 0.001); (3) a mean duration of hospitalization significantly (P = 0.05) longer, on average by 1.6 d; (4) a morbidity rate after 30 days significantly higher (16.2% vs. 4.9%, P = 0.01); and, (5) higher costs. There was no significant difference concerning mortality rate (nil), conversion rate (1.5%) and recurrence rate (1.3% vs. 0.6%, non significant). CONCLUSION: Surgical training for laparoscopic treatment of inguinal hernias was associated with a longer operation time and hospital stay, and with higher morbidity and costs. After a good initial training in a teaching hospital, surgeons were capable of performing laparoscopic repair of inguinal hernias with good results.

Proximal bile duct cancer: high resectability rate and 5-year survival.

OBJECTIVE: To review and update the authors' experience with resectional surgery for proximal bile duct carcinoma (Klatskin tumor) and assess the role of liver resection over the past 25 years. BACKGROUND: Until recently, resection of proximal bile duct carcinoma was uncommon, with most patients undergoing palliative procedures. The authors adopted a radical surgical approach aimed at definitive cure in 1974. Recent reports suggest that resection improves outcome. METHODS: The records of 40 of 94 patients (23 men, 17 women, age range 34-81 years) diagnosed with proximal bile duct carcinoma who underwent resection between 1968 and 1993 were reviewed. According to the Bismuth classification, there were five type I, four type II, 25 type III, and six type IV lesions; 11 patients underwent tumor resection alone, and 25 patients had combined tumor and liver resection (seven of these also underwent an associated regional vascular resection). In 3 patients, venous allografts were harvested from cadaveric donors and used to reconstruct the portal vein. Four patients underwent liver transplantation; in two, organ cluster-type resections including the liver with porta hepatitis and pancreas were performed. RESULTS: The resectability rate in the more recent period of the study was 49.4%. Most type I, three (of four) type II, T in situ, T1a, T1b, and all stage 0 tumors were resected without hepatectomy. In the other subgroups of tumors, the main surgical procedure was hepatectomy. Thirty-day mortality was 12.5%. After tumor resection alone, survival at 1, 3, and 5 years was 81.8%, 45.5%, and 27.3%, respectively. After tumor resection and hepatectomy without vascular resection, 1-, 3-, and 5-year survival was 66.7%, 16.7%, and 6%, respectively. With vascular resection, survival rates were similar: 64%, 20%, and 4%, respectively. CONCLUSION: The type of surgery required to achieve cure is closely related to tumor location, TNM classification, and staging. Increasing resectability through the use of hepatectomy improves survival and offers a chance of cure in patients with more advanced disease.

The effect of the learning curve on the outcome of laparoscopic treatment for gastroesophageal reflux.

The laparoscopic treatment for gastroesophageal reflux (GR) by partial (PF) or total (TF) fundoplication is the current surgical treatment of choice after failure of appropriate medical treatment. The overall results with fundoplication include the initial learning period, during which the rate of complications, conversions, and duration of surgery and hospitalization are assumed to be greater. The aim of this study was to compare the results of laparoscopic treatment for GR in three groups of consecutive patients to determine the effect of the learning period on outcome. One hundred and fifty-six patients (88 men and 68 women) with an average age of 52.3 years (range, 18-78) were included. Surgery was indicated for failure or early relapse after the end of medical treatment or a symptomatic sliding hernia. The preoperative workup (endoscopy, barium meal, or esophageal pH monitoring) was governed by the clinical picture. The choice between TF and PF was based on the results of pH monitoring. Three groups of patients were chronologically defined. The parameters that were examined were the type of preoperative exploration, the type of fundoplication, the operative technique, the conversion rate, the mortality and morbidity rates, the duration of surgery and hospitalization, and the results at short- and medium-term follow-up. The three groups were comparable with respect to patient characteristics and the nature of their GR. All patients had an endoscopy, 91% had a barium meal, 77.5% underwent esophageal manometry, and 67% had pH monitoring. One hundred and thirty-six patients had a TF and 20 had a PF. Rossetti type TF became the reference procedure (67% in group III) and closure of the diaphragmatic crura was performed systematically in group III (100%). The duration of surgery was significantly reduced between groups I and groups II and III (140, 100, 80 minutes, respectively). The rate of conversion, due to a variety of causes, decreased from 9.8% to 3.8%, and then to 0%. The average duration of hospitalization decreased from 5.8 to 4.2 days (p = 0.01). There was no mortality and the morbidity rate decreased from 15% to 3.8%, and then to 0%. There were seven cases of relapse (4.6%), five in group I (10%) and two in group II (4%), with no cases in group III, although the follow-up in group III was shorter. There is an effect of the learning curve on the outcome of treatment for GR, and this must be taken into account in the training of surgeons (training within experienced departments and guidance during their initial interventions) and also in publications to allow a more accurate comparison of this technique with other treatments for GR.

Thromboembolism in laparoscopic surgery: risk factors and preventive measures.

The aim of this study was to assess the risk of clinical thromboembolism in laparoscopic digestive surgery. From June 1992 to June 1997, 2,384 consecutive patients were studied. All received perioperative prophylaxis with low-molecular-weight heparin (LMWH), which was continued until full mobility was regained. Eight cases (0.33%) of deep venous thrombosis were noted, but there were no cases of pulmonary embolus. In six cases (five cholecystectomies with reverse Trendelenburg position and one inguinal hernia repair), release of the pneumoperitoneum took longer than 2 hours, and in two cases (one rectopexy and one sigmoid colectomy for diverticulitis), longer than 3 hours. In six of the eight cases, the diagnosis of DVT was made after LMWH had been ceased and the patient had been discharged. All cases were diagnosed before the 10th postoperative day. Pneumoperitoneum is felt to predispose to deep venous thrombosis. Long operations and reverse Trendelenburg position are further potentiating factors. Thromboprophylaxis for laparoscopy should be the same as for conventional surgery, i.e., tailored to individual risk and continued for a minimum of 7 to 10 days. We also recommend using graduated compression stockings, maintaining a relatively low insufflation pressure, keeping use of the reverse Trendelenberg position to a minimum, and intermittently releasing the pneumoperitoneum in longer procedures.

Does laparoscopy reduce the incidence of unnecessary appendicectomies?

The aim of this study was to evaluate the impact of laparoscopic appendicectomy on the incidence of histologically normal appendices. Between 1987 and 1997, 1,220 patients (average age 23.5 years [17-73]; 841 women [69%]) had appendicectomy due to the presence of at least one of the following three criteria: right iliac fossa guarding, fever >38 degrees C, and leukocytosis >10,000. Patients were divided into two groups: one group of 930 patients were operated on using the classic Mac Burney approach and the other group of 355 patients underwent laparoscopic exploration, with an appendicectomy performed if macroscopic abnormalities were observed (290 cases). In all cases, the appendices were examined blind and classified as normal or pathologic, with the latter divided with respect to the nature and severity of the lesions. In the Mac Burney group, the incidence of histologically normal appendices was 25.1%. In the laparoscopic group, the incidence was only 8.2% (p=0.015). The types of pathologic appendices were identical between the two groups. In 65 cases (18.3%), a macroscopically normal appendix was left in place. In 56 cases the symptoms were due to another identified cause, however, in 10 cases no cause was found. All patients were followed-up for an average of 3 years. One patient (1.8%) had a second operation (an appendicectomy), which revealed minor histologic lesions. The problem is the inability of the operator to differentiate between a healthy and a pathologic appendix on laparoscopy. The risk of false-positives and false-negatives is approximately 10%. Diagnostic difficulties usually occur in the initial phase of the disease with acute mucosal involvement in a morphologically normal appendix. At this stage the outcome cannot be predicted, although appropriate antibiotic treatment can be effective. This study shows that laparoscopy significantly reduces the number of histologically normal appendices as compared to a conventional Mac Burney operation. This can only be achieved by not removing macroscopically normal appendices, a small proportion of which (5-10%) could be cases of early appendicitis with only mucosal involvement. In the absence of other causes of the symptoms, a 3-day course of antibiotics can be tried to treat possible mucosal lesions. This approach reduces costs without having adverse consequences on the outcome.
