Clinical evaluation of fibrin glue in the prevention of anastomotic leak and internal hernia after laparoscopic gastric bypass: preliminary results of a prospective, randomized multicenter trial.

BACKGROUND: Gastro-jejunal anastomotic leak and internal hernia can be life-threatening complications of laparoscopic Roux-en-Y gastric bypass (LRYGBP), ranging from 0.1-4.3% and from 0.8-4.5% respectively. The safety and efficacy of a fibrin glue (Tissucol) was assessed when placed around the anastomoses and over the mesenteric openings for prevention of anastomotic leaks and internal hernias after LRYGBP. METHODS: A prospective, randomized, multicenter, clinical trial commenced in January 2004. Patients with BMI 40-59 kg/m2, aged 21-60 years, undergoing LRYGBP, were randomized into: 1) study group (fibrin glue applied on the gastro-jejunal and jejuno-jejunal anastomoses and the mesenteric openings); 2) control group (no fibrin glue, but suture of the mesenteric openings). 322 patients, 161 for each arm, will be enrolled for an estimated period of 24 months. Sex, age, operative time, time to postoperative oral diet and hospital stay, early and late complications rates are evaluated. An interim evaluation was conducted after 15 months. RESULTS: To April 2005, 204 patients were randomized: 111 in the control group (mean age 39.0+/-11.6 years, BMI 46.4 +/- 8.2) and 93 in the fibrin glue group (mean age 42.9+/-11.7 years, BMI 46.9+/-6.4). There was no mortality or conversion in both groups; no differences in operative time and postoperative hospital stay were recorded. Time to postoperative oral diet was shorter for the fibrin glue group (P = 0.0044). Neither leaks nor internal hernias have occurred in the fibrin glue group. The incidence of leaks (2 cases, 1.8%) and the overall reoperation rate were higher in the control group (P=0.0165). CONCLUSION: The preliminary results suggest that Tissucol application has no adverse effects, is not time-consuming, and may be effective in preventing leaks and internal hernias in morbidly obese patients undergoing LRYGBP.

Laparoscopic splenectomy for non-traumatic diseases.

At present, laparoscopic splenectomy (LS) is mostly indicated in hematologic benign diseases, and in case of normal size spleen it is considered the gold standard. The technique is under a continuous evolution and several studies have demonstrated feasibility and safety of laparoscopic approach also in case of massive splenomegaly, malignant diseases and even in the treatment of selected cases traumatic lesions. LS is an advanced surgical procedure that requires a management of a full trained team involved in the preoperative preparation, surgical strategy and postoperative care. A fully comprehension of the impact of the surgical strategy is needed to plan the treatment of diseases that often are managed in a multidisciplinary setting. Indications and contraindications to surgery does not differ significantly from open traditional splenectomy, but the nature of the disease and the volume of the spleen can greatly influence the operation. A preoperative study with definition of these parameters along with a standard preparation to surgery is required. Over the years the technique has been developed and adapted to respond to emergent necessities related to those parameters. Anterior, semilateral, later and hand assisted approaches offer advantages and drawbacks that should be weighed in each case. They depend on surgeons preferences but most of the time are related to the preoperative studies, even when new surgical tools (i.e. harmonic scalpel and radiofrequency). No randomized, prospective trials have been conducted, however several studies with strong evidence have shown that less surgical trauma, intraoperative blood loss, early hospital discharge, rapid return to normal activities and better cosmesis can be obtained with a laparoscopic approach.

The Italian Group for LAP-BAND: predictive value of initial body mass index for weight loss after 5 years of follow-up.

BACKGROUND: Laparoscopic of the LAP-BAND System placement stage of obesity is a safe operation, but its indication in terms of stage of obesity is controversial. The aim of this study was to evaluate the 5 years stage of obesity results for weight loss in patients with varying preoperative ranges of body mass index (BMI). METHODS: Data were obtained from the Italian Collaborative Study Group for LAP-BAND System (GILB) registry. Detailed information was collected on a specifically created database (MS Access 2000) for patients operated on in Italy from January 1996 to 2003. Patients operated on between January 1996 and December 1997 were allocated to four groups according to preoperative BMI range: 30-39.9 kg/m(2) (group A), 40-49.9 kg/m(2) (group B), 50-59.9 kg/m(2) (group C), and =60 kg/m(2) (group D) percent estimated weight loss respectively. Postoperative complications, mortality, BMI, BMI loss, and (%EWL) were considered in each group. Data are expressed as mean +/- SD, except as otherwise indicated. Statistical analysis was done by means of Fisher's exact test, and p < 0.05 was considered significant. RESULTS: After 5 years from LAP-BAND System surgery, 573 of 3,562 patients were eligible for the study. One hundred fifty-five of 573 (27.0%) were lost to follow-up, 24 of 418 (5.7%) underwent band removal due to complications (gastric pouch dilation, band erosion), eight of 418 (1.9%) were converted to other bariatric procedures, five of 418 (1.2%) died of causes not related to the operation or the band, and 381 of 573 (66.5%) were available for follow-up. Based on 96, 214, 64, and seven patients their preoperative BMI, Were allocated to groups A, B, C, and D, respectively. At time of follow-up mean BMI was 27.5 +/- 5.2 in group A, 31.6 +/- 4.7 in group B, 37.6 +/- 17.3 in group C, and 41.4 +/- 6.9 kg/m(2) in group D. Mean BMI loss was 9.8 +/- 5.4, 12.9 +/- 5.2, 15.8 +/- 8.1, and 23.2 +/- 4.9 kg/m(2), respectively, in groups A, B, C, and D. Mean %EWL at the same time was 54.6 +/- 32.3 in group A, 54.1 +/- 17.2 in group B, 51.6 +/- 35 in group C, and 59.l +/- 17.1 in group D. CONCLUSION: Initial BMI in this series did not correlate with %EWL 5 years after the operation. In fact %EWL was almost the same in each group, independent of preoperative weight. Initial BMI was an accurate indicator of the results obtained 5 years after LAP-BAND in group C (50-59.9 kg/m(2)) and D (=60 kg/m(2)) patients, who remained morbidly obese despite their %EWL.

Italian Group for Lap-Band System: results of multicenter study on patients with BMI < or =35 kg/m2.

BACKGROUND: The Lap-Band System is the most common bariatric operation world-wide. Current selection criteria do not include patients with BMI < or = 35. We report the Italian multicentre experience with BMI < or = 35 kg/m(2) over the last 5 years. PATIENTS AND METHODS: Data were obtained from 27 centres involved in the Italian Collaborative Study Group for Lap-Band System. Detailed information was collected on a specially created electronic data sheet (MS Access 2000) on patients operated in Italy since January 1996. Items regarding patients with BMI < or = 35 were selected. Data were expressed as mean +/- SD except as otherwise indicated. RESULTS: 225 (6.8%) out of 3,319 Lap-Band patients were recruited from the data-base. 15 patients, previously submitted to another bariatric procedure (BIB =14; VBG= 1) were excluded. 210 patients were eligible for study (34M/176F, mean age 38.19+/-11.8, range 17-66 years, mean BMI 33.9+/-1.1, range 25.1-35 kg/m(2), mean excess weight 29.5+/-7.1, range 8-41). 199 comorbidities were diagnosed preoperatively in 55/210 patients (26.2%). 1 patient (0.4%) (35 F) died 20 months postoperatively from sepsis following perforation of dilated gastric pouch. There were no conversions to laparotomy. Postoperative complications presented in 17/210 patients (8.1%). Follow-up was obtained at 6, 12, 24, 36, 48 and 60 months. At these time periods, mean BMI was 31.1+/-2.15, 29.7+/-2.19, 28.7+/-3.8, 26.7+/-4.3, 27.9+/-3.2, and 28.2+/-0.9 kg/m(2) respectively. Co-morbidities completely resolved 1 year postoperatively in 49/55 patients (89.1%). At 60 months follow-up, only 1 patient (0.4%) has a BMI >30. CONCLUSIONS: Although surgical indications for BMI < or = 35 remain questionable, the Lap-Band in this study demonstrated that all but 1 patient achieved normal weight, and most lost their co-morbidities with a very low mortality rate.

Bile duct injuries during laparoscopic cholecystectomy: a 1994-2001 audit on 13,718 operations in the area of Rome.

BACKGROUND: Bile duct injuries (BDIs) during laparoscopic cholecystectomy (LC) still are reported with greater frequency than during open cholecystectomy (OC). METHODS: In 1999, a retrospective study evaluating the incidence of BDIs during LC in the area of Rome from 1994 to 1998 (group A) was performed. In addition, a prospective audit was started, ending in December 2001 (group B). RESULTS: In group A, 6,419 LCs were performed (222 were converted to OC; 3.4%). In group B, 7,299 LCs were performed (225 were converted to OC; 3.1%). Seventeen BDIs (0.26%) occurred in group A and 16 (0.22%) in group B. Overall, mortality and major morbidity rates were 12.1% and 30.3%, respectively, without significant differences between the two groups. CONCLUSIONS: The incidence and clinical relevance of BDIs during LC in the area of Rome appeared to be stable over the past 8 years and were not influenced by the use of a prospective audit, as compared with a retrospective survey.

Abdominal wall recurrences after colorectal resection for cancer: results of the Italian registry of laparoscopic colorectal surgery.

PURPOSE: The purpose of the present study was to evaluate prospectively the abdominal wall recurrence rate after laparoscopic resection for colorectal cancer, to analyze the impact of the learning curve on abdominal wall recurrence, and to assess the outcome of those patients. METHODS: The Italian Registry of Laparoscopic Colorectal Surgery database was analyzed to obtain data on cancer patients with abdominal wall recurrence, concomitant local or distant metastases, and interval between initial surgery and diagnosis of trocar site or minilaparotomy recurrences. The records of the initial procedures and the technique of specimen removal were reviewed. RESULTS: From January 1992 to July 2000, 2,583 patients (1,753 cases of carcinomas and 830 cases of benign diseases) were recorded. The malignant lesions were located on the right colon in 19 percent, the left colon in 48.8 percent, and rectum in 32.2 percent. Sixteen patients with histologic evidence of colorectal adenocarcinoma recurrences at the abdominal wall were observed (0.9 percent). Ten patients presented an advanced stage (III for 7 patients and IV for 3 patients). Eleven cases occurred during the learning curve period (the first 50 consecutive cases). The median survival time after abdominal wall recurrence diagnosis was 16 (range, 12-60) months. By July 2000 only two patients were alive. CONCLUSIONS: The results of the Italian prospective Registry of Laparoscopic Colorectal Surgery confirm that the incidence of abdominal wall recurrences is similar to that reported in open studies (<1 percent). Most abdominal wall recurrences occurred in the learning curve period, suggesting that surgical experience may play a role in the development of this outcome. The prognosis of these patients is very poor.

Laparoscopic adjustable silicone gastric banding: prospective evaluation of intragastric migration of the lap-band.

Intragastric prosthesis (Lap-Band, BioEnterics Co., Carpinteria, CA, U.S.A.) migration is one of the major long-term complications of laparoscopic adjustable silicone gastric banding. The causes, clinical signs, timing, and overall incidence of band entrapment have not been prospectively investigated in a large series. The purpose of this study was to assess prospectively the incidence of Lap-Band intragastric migration and to establish the safety and effectiveness of minimally invasive band removal. Between January 1996 and June 2000, 148 consecutive patients enrolled in a multidisciplinary bariatric program underwent laparoscopic adjustable silicone gastric banding. In the follow-up treatment, gastrointestinal endoscopy was performed routinely. One hundred twenty-three patients with a minimum follow-up period of 12 months were entered into the study group. Eleven (9.2%) patients had long-term major complications. Intragastric band migration was observed in nine (7.5%) patients. The diagnosis was established by routine endoscopy between 10 and 41 months after surgery. Five erosions occurred in the first 30 cases (learning curve period). In six patients, the band was removed by an intragastric endoscopic-assisted approach avoiding laparotomy. The remaining three patients are under endoscopic surveillance. The results of this study show that routine upper gastrointestinal endoscopy can discover asymptomatic band migrations early. Band erosion did not require emergency treatment and can be removed safely by a minimally invasive approach.

Laparoscopic treatment of gastric stromal tumors.

BACKGROUND: The laparoscopic resection of gastric stromal tumors (GST) is being performed with increased frequency. METHODS: Between November 1993 and October 1998, nine consecutive patients with benign and low-grade gastric stromal tumors underwent laparoscopic resection using intraoperative endoscopy. For lesions located on the anterior wall (three cases), a direct approach was utilized. Lesions located on the posterior wall were resected via a transgastric approach (four cases) or through a small opening on the omentum or on the gastrocolic ligament (two cases). Excision of the lesions was performed manually by means of electrocautery and scissors in eight cases; the gastric incisions were closed by manual running suture. An endoscopic stapler device was used in one case only. RESULTS: All patients were successfully treated laparoscopically; there were no conversions to open surgery. Operative time ranged from 75 to 120 min. There was one bleeding from the suture line of the gastric wall postoperatively that was treated conservatively. The average postoperative hospital stay was 4 days (range, 2-6). CONCLUSIONS: In light of the results reported in the literature and on the basis of the present work, it seems that laparoscopic resection of GST should be considered as the treatment of choice. Wedge resection of anterior wall lesions is generally performed. The treatment of posterior wall lesions is still controversial. In our opinion the direct approach should be reserved for lesions located on the posterior wall of the body, which can be easily reached through the greater omentum, while the transgastric approach should be preferred for lesions located on the fundus and antrum. Manual excision allows a tailored operation; hand-sewn sutures are always feasible, and they are cheaper than stapled ones.

Efficacy of repeated cycles of chemo-immunotherapy with thymosin alpha1 and interleukin-2 after intraperitoneal 5-fluorouracil delivery.

We have used chemo-immunotherapy with 5-fluorouracil (5-FU), thymosin alpha1 (T alpha1) and interleukin-2 (IL-2) to treat multiple liver metastases from colorectal cancer induced by DHD/K12 cells in syngeneic BDIX rats, comparing one and two cycles of treatment, and different treatment combinations. 5-FU was delivered loco-regionally as a continuous infusion via an intraperitoneal (i.p.) catheter from a subcutaneously implanted mini-pump, a method we developed for this study. We show here that two cycles of a triple chemo-immunotherapy regimen significantly increased the average survival time compared to one cycle, and compared to untreated controls or those treated with two cycles of 5-FU alone. At 150 days, two rats treated with two cycles of triple therapy were cured, showing no signs of cancer at autopsy; all the other rats died before this time. Triple chemo-immunotherapy resulted in significantly fewer extra-hepatic metastases than in the controls and in those treated with 5-FU only. Further, we found that two cycles of triple treatment significantly increased the absolute number of peripheral T cells expressing IL-2 receptor, CD4 and CD8 compared to controls. We conclude that two cycles of chemo-immunotherapy with 5-FU, T alpha1 and IL-2 were superior to one cycle of treatment and to other treatments tested. Our results suggest that the triple therapy acts by increasing numbers of effector T cells. This method shows promise for the use of multi-cycle chemo-immunotherapy in the treatment of unresectable metastases of colorectal cancer in humans.

Management of abdominal lymphoproliferative diseases in the era of laparoscopy.

BACKGROUND: The treatment of lymphoproliferative diseases requires extensive histological, immunohistochemical, and cytogenetic diagnosis. The aim of this study was to analyze the results of 66 laparoscopic procedures in the diagnosis, staging, and restaging of hematological malignancies localized in the abdominal cavity. METHODS: Between July 1993 and March 1998, 64 consecutive patients (28 male and 36 female; mean age 46.6 years, range 7 to 69) with diagnosed or suspected lymphoproliferative diseases were referred for primary diagnosis or reassessment and for staging/restaging. RESULTS: Sixty-two out of 66 procedures (93.9%) were completed laparoscopically. CONCLUSIONS: The minimally invasive approach, in the management of lymphoproliferative diseases, is able not only to provide an adequate specimen for proper diagnostic techniques, but also, when compared with open surgery, to offer a large number of advantages.

Laparoscopic cholecystectomy and intraoperative endoscopic sphincterotomy in the treatment of cholecysto-choledocholithiasis.

BACKGROUND: A single-stage minimally invasive procedure would be optimal for management of cholecysto-choledocholithiasis. Two alternative strategies are available: management by laparoscopy alone or a combined laparoscopic-endoscopic approach. This study evaluates the results of the latter procedure. METHODS: From June 1993 to September 1997, 1400 patients with symptomatic biliary stone disease were evaluated for laparoscopic cholecystectomy. Intraoperative cholangiography was performed on the basis of a preoperative suspicion of bile duct stones; bile duct stone treatment was by intraoperative endoscopic retrograde sphincterotomy. RESULTS: Intraoperative cholangiography was performed because of a preoperative suspicion of a bile duct abnormality in 141 of 1400 patients (10%) undergoing laparoscopic cholecystectomy because of biliary stone disease. Of those 141 patients, 54 (38.3%) presented with pathologic findings (bile duct stone [52] and papillary stenosis [2]); all 54 underwent intraoperative endoscopic sphincterotomy. Complete clearance of the ductal stones was achieved in 43 patients (82.7%) by intraoperative sphincterotomy, and in 9 patients by an additional postoperative endoscopic procedure. Laparoscopic cholecystectomy was carried out in all cases. There were no conversions to an open operation. Postoperative course in the uncomplicated cases was comparable to that for laparoscopic cholecystectomy alone. The postoperative complication rate was 5.6% and mortality 1.8%. Mean hospital stay was 3.3 days (range 2 to 16). At a mean 38 months follow-up, no complications related to the laparoscopic-endoscopic procedure were observed. CONCLUSION: The intraoperative combined laparoscopic-endoscopic approach seems to be a feasible and effective management of cholecysto-choledocholithiasis, saving patients a subsequent invasive procedure.

Laparoscopic and intraoperative ultrasound.

OBJECTIVE: Intraoperative ultrasound has gradually expanded in the last two decades to a variety of surgical specialties and has gained an established role in many surgical procedures. Laparoscopic and thoracoscopic ultrasound are the latest modes of intraoperative sonography. They have been introduced mainly to overcome the two major drawbacks of laparoscopy, i.e. the capability of showing only the surface of the organs and the lack of manual palpation of the anatomical structures. We review and discuss the established and the most recent applications of intraoperative and laparoscopic ultrasound. MATERIAL AND METHODS: The technology, new indications and results of intraoperative and laparoscopic ultrasound are reviewed. This review is based on the experience gained in our Institution during more than 500 surgical procedures and the analysis of the literature on the subject. RESULTS: The yield of intraoperative and laparoscopic ultrasound consists in confirming preoperative studies and acquiring new data which would not be available otherwise. An important role of these techniques is determining the anatomy of the involved organs, thus providing a guidance for surgery. Both techniques have an important role in surgical decision-making, particularly with respect to hepatic, biliary and pancreatic malignancies. In some series the rate of major changes in the surgical strategy can be as high as 38%. A relatively new application of intraoperative ultrasound is the possibility to perform interstitial therapy of tumors at the time of the initial surgery. This can be useful, for example, in patients undergoing liver resection, when other unresectable lesions are found in a different segment or in the contralateral lobe. Finally, laparoscopic sonography has an important role in staging abdominal neoplasm, providing more information than preoperative imaging and laparoscopic exploration. This feature can be used to effectively stage gastrointestinal malignancies, pancreatic carcinoma, and abdominal lymphomas. CONCLUSION: The application of intraoperative ultrasound will increase in the era of minimally access surgery and this will be dependent not only on technical improvements in ultrasound technology. Indeed, it may be expected that a variety of open procedures will be performed with videolaparoscopic monitoring and will need the guidance of laparoscopic sonography. In the future, the staging of abdominal neoplasm may be markedly improved by laparoscopy combined with laparoscopic ultrasound; however a cost-benefit analysis of these techniques and a comparison with preoperative tests should be carried out.

Use of the somatostatin analogue octreotide to localise and manage somatostatin-producing tumours.

BACKGROUND: Somatostatin receptor scintigraphy (SRS) and octreotide therapy have both changed the management of gastroenteropancreatic endocrine tumours, but very few data are available on the use of SRS and octreotide to visualise and treat somatostatinomas. METHOD: The results of SRS and octreotide treatment in three somatostatinoma patients were examined. RESULTS: SRS was able to detect extensive hepatic involvement in patient 1, one hepatic and one pancreatic lesion in patient 2, and one hepatic lesion in patient 3. Octreotide therapy (0.5 mg/day subcutaneously) was effective in decreasing plasma levels of somatostatin in all three patients. Symptoms (diabetes and diarrhoea) were greatly improved in the two patients with "somatostatinoma syndrome". CONCLUSION: The study shows that somatostatinoma, like most other gastroenteropancreatic endocrine tumours, possesses functioning somatostatin receptors.

Laparoscopic resection of solitary gastric schwannoma.

We report a case of successful laparoscopic resection of a solitary schwannoma of the gastric fundus performed on emergency. The patient was a 52-year-old man who presented with an upper gastrointestinal hemorrhage. At admission, the endoscopy and hydro-CT scan showed a submucosal tumor, 2.5 cm in maximum diameter, with an area of central ulceration arising from the anterior wall of the gastric fundus. A wedge laparoscopic resection of the gastric wall was performed under endoscopic guidance. The defect in the anterior wall was repaired in part by linear stapler and in part using a continuous suture. The postoperative recovery was uneventful and the patient was discharged on the 4th postoperative day. Laparoscopic approach represents a safe and efficient approach for the treatment of benign tumors of the stomach, also on emergency basis.

Minimally invasive approach for the treatment of idiopathic varicocele.

Laparoscopic ligation of the spermatic veins represents a new approach for the treatment of the idiopathic varicocele. This procedure was performed in 28 consecutive patients. The diagnosis was based on physical examination and Doppler ultrasonography. The indications for surgery were (a) infertility and abnormal semen analyses (15 patients), (b) scrotal pain (six patients), and (c) psychological reasons (seven patients). One patient underwent concomitant hernioplasty. Two cases presented with a recurrence after 6 and 12 months, respectively. The mean operative time was 34 +/- 11 min in unilateral cases and 47 +/- 9 min in bilateral cases. In one patient with left inguinal hernia and varicocele, the operative time was 70 min. All patients were discharged the day after operation without antibiotics and analgesics and resumed normal activity within 5 to 9 days, depending on age and occupation. Postoperative semen analyses (at 12 months' follow-up) were obtained from seven patients and demonstrated an improvement in semen motility (preoperative 40% versus postoperative 56%). This study confirms that laparoscopic treatment of varicocele is safe, minimally invasive, and, according to National Health Service fees, less costly than radiological occlusion procedures.

Laparoscopic colorectal resection. A multicenter Italian study.

BACKGROUND: The aim of the present study was to evaluate retrospectively the experience of six surgical units currently performing laparoscopic colorectal surgery. METHODS: From November 1991 to January 1994, 200 patients (103 male, 97 female; mean age 62.5 years) were candidates for, and received, laparoscopic colorectal resection for benign (54) or malignant (196) lesions. All the units excluded patients with locally advanced organ tumors and all cases with suspected perforation and ascites. One center submitted to laparoscopic resection only stage I and IV adenocarcinoma. All surgeons considered obesity a relative contraindication. The following data were analyzed: indications, conversion rate to open surgery, operative time, morbidity and mortality, resumption of gastrointestinal function, number of lymph nodes harvested, hospital stay. RESULTS: Twenty-one out of 200 patients were converted to open surgery (10.5%); 37 patients had a complete laparoscopic procedure (17.1%); 137 had an assisted resection (68.5%); and the remaining 5 patients had a facilitated resection. The mean operative time was 208 min (90-480) for assisted resection and 275 min (54-550) for complete laparoscopic resection. The mortality rate was 1.7%; the overall morbidity was 19.6% (major complications 11.2%). All patients quickly became ambulatory and showed a prompt resumption of gastrointestinal functions, and less postoperative pain if compared with converted cases. The average number of lymph nodes was 12.1 (range 1-32). The mean hospital stay was 8.6 days (range 5-14.5). The mean follow-up was 16 months (range 6-24). The recurrence rate 11.7%. CONCLUSIONS: Laparoscopy seems to offer the possibility of minimally invasive treatment, but long-term follow-up is needed to evaluate the efficacy of laparoscopic surgery in the treatment of colorectal cancer.

Laparoscopic excision of posterior gastric wall leiomyoma.

The development of laparoscopic surgery has suggested new technical procedures for the treatment of several pathologies. Herein we report a case of laparoscopic excision of a posterior gastric wall leiomyoma. The technique reproduces that used in conventional surgery but with a transgastric approach, and the advantages of minimally invasive surgery are maintained. This laparoscopic approach may be considered an alternative strategy for surgical treatment of benign tumors of the stomach.

Sequential endoscopic-laparoscopic treatment of cholecystocholedocholithiasis.

Preoperative common bile duct (CBD) clearance with endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterotomy (ES) is routinely performed in many centers where laparoscopic cholecystectomy (LC) is the procedure of choice for the treatment of cholelithiasis. The purpose of this study was to evaluate prospectively the results of the sequential endoscopic-laparoscopic management in patients with gallstones and suspected CBD stones. From November 1990 to May 1993, 700 consecutive patients were evaluated for LC. Preoperative workup included clinical history and physical examination; serum levels of bilirubin, alkaline phosphatase, and amylase; and ultrasonography. Preoperative ERCP was indicated in cases with previous or present jaundice or acute pancreatitis, altered liver or pancreatic blood tests, dilated CBD (> 6 mm) and CBD stones at ultrasonography. If CDB pathology was confirmed, ES was performed and treatment attempted. All patients were assigned to undergo LC within 48 h. Morbidity, mortality, hospital stay, and disability were recorded. Of 700 patients, 49 (7%) underwent ERCP. In 26 patients (54.2%), CBD stones were identified; ES was performed and stone extraction succeeded in 22 patients (84.6%). Two patients with intrahepatic stones were successfully treated with a percutaneous transhepatic approach and then underwent surgery. Two patients with cholecystocholedochal fistula underwent open surgery. In two cases ERCP showed a papillary stenosis, which was treated with ES. Of 44 patients, 35 (79.5%) underwent LC within 48 h. The overall morbidity (ERCP/ES plus LC) was 10.4%. No mortality occurred. The mean hospital stay was 4.5 days. Return to normal activities occurred within 11 days after LC. This sequential approach resulted in a safe and effective treatment of cholecystocholedocholithiasis and a decrease in the overall costs.
