Laparoscopic pyeloplasty: the first 100 cases

PURPOSE: Laparoscopic pyeloplasty was developed as a minimally invasive alternative to an open procedure for the treatment of ureteropelvic junction obstruction. Long-term followup has not yet been reported. We present experience with the first 100 consecutive cases of laparoscopic pyeloplasty performed at our institution. MATERIALS AND METHODS: A retrospective review of 100 consecutive laparoscopic pyeloplasties in 99 patients (means age 37.3 years) between August 1993 and January 1999 was performed. All patients had radiographic evidence of obstruction with signs, symptoms or deterioration of renal function. Repair was for primary ureteropelvic junction obstruction in 83 patients and secondary obstruction in 17. The 4 types of repairs performed were Anderson-Hynes dismembered (71 cases), Y-V plasty (20), Heineke-Mirhulicz (8) and Davis intubated ureterotomy (1). Type of repair used was dictated by intraoperative findings. Twenty patients had nonobstructing renal stones and underwent concomitant pyelolithotomy. All patients were assessed for symptoms and radiographic evaluation for anatomical obstruction. RESULTS: Average operating room time was 4.2 hours, which decreased with surgeon experience. Average blood loss was 181 cc and hospital stay was 3.3 days. Two patients required blood transfusion. A crossing vessel was found in 57 patients. With a mean clinical and radiographic followup of 2.7 and 2.2 years, respectively, 96% of the patients were free of obstruction on followup radiographic imaging. Of the patients who underwent concomitant pyelolithotomy, 18 (90%) were stone-free at last followup. All failures occurred within the first postoperative year. There were 12 complications in this series. CONCLUSIONS: In experienced hands laparoscopic pyeloplasty is an effective alternative treatment for symptomatic ureteropelvic junction obstruction. The results appear durable and comparable to open pyeloplasty with decreased postoperative morbidity.     

Laparoscopic cholecystectomy. A report of 100 cases]

From February to May in 1991, 100 cases of gallstones underwent the attempt of laparoscopic cholecystectomy. There were two failures owing to extensive adhesion. The operative time was 72.5 +/- 32 minutes in the first 50 cases, and 46.9 +/- 15 minutes thereafter. Among them 8 cases were coelio-drained for 24 hours with very little thin bloody drainage. There were not postoperative complications. The hospital stay was 3-7 days. All patients were back to their normal daily-work within 10 days. Hence this new type of cholecystectomy is characterized by less trauma and pain, and fast postoperative recovery.     

Laparoscopic pyeloplasty: an analysis of first 100 cases and important lessons learned

Aim  

Laparoscopic pyeloplasty (LP) is a minimally invasive approach that is becoming a standard treatment of ureteropelvic junction obstruction (UPJO). It is providing similar results when compared with open surgery. We here present our technique and analyses of experience of our first 100 cases.

Laparoscopic colorectal surgery. Analysis of the first 237 cases

This study was made to prospectively assess the results of our first 237 consecutive patients who underwent laparoscopic or laparoscopic-assisted colorectal procedures. Between May 1995 and July 1999, two hundred thirty seven laparoscopic (assisted) colorectal procedures were performed: 97 sigmoidectomies, 31 right hemicolectomies, 26 rectosigmoidectomies, 23 abdominoperineal rectum amputations and 60 other procedures. The following parameters were recorded and analysed: patients gender, age, diagnosis, procedure, conversion to open surgery, peroperative and postoperative complications, duration of procedure, mortality and length of hospitalization. There were 104 men (44%) and 133 women (56%) with a mean age of 62 years. Hundred and fifty-one operations were performed for benign indications (diverticular disease (51.6%), benign colonic polyps (17.5%) and others (30.9%)) and 86 for cancer (palliative and curative). The conversion rate was 4%. Postoperative complications occurred in 65 patients (27%). In 20% of these cases re-operation was necessary. The most common cause was bowel obstruction. Surgery lasted an average of 110 minutes. Mean overall hospital stay was 11 days. Sixty per cent left the hospital within eight days after operation. The 60-day mortality rate was 2.9%. The feasibility and safety of laparoscopic colorectal surgery has been established in a variety of procedures for different indications. Care must be taken in the case of acute diverticulitis which in our series is associated with higher minor and major complication rate and conversion rate. Although our results for malign cases are good, the definitive incidence of neither port-site metastasis nor local recurrence is known and no long-term results after laparoscopic surgery for carcinoma are available, we believe that curative procedures for cancer should continue to be carried out only within the framework of prospective studies unless the patient is more than 75-year old, is in bad general condition or when a palliative procedure has to be performed.

Laparoscopic repair of giant paraesophageal hernia: 100 consecutive cases

OBJECTIVE: To summarize the authors' laparoscopic experience for paraesophageal hernia (PEH). SUMMARY BACKGROUND DATA: Laparoscopic antireflux surgery and repair of small hiatal hernias are now routinely performed. Repair of a giant PEH is more complex and requires conventional surgery in most centers. Giant PEH accounts for approximately 5% of all hiatal hernias. Medical management may be associated with a 50% progression of symptoms and a significant death rate. Conventional open surgery has a low death rate, but complications are significant and return to routine activities is delayed in this frequently elderly population. Recently, short-term outcome studies have reported that minimally invasive approaches to PEH may be associated with a lower complication rate, a shorter hospital stay, and faster recovery. METHODS: From July 1995 to February 2000, 100 patients (median age 68) underwent laparoscopic repair of a giant PEH. Follow-up included heartburn scores and quality of life measurements using the SF-12 physical component and mental component summary scores. RESULTS: There were 8 type II hernias, 85 type III, and 7 type IV. Sac removal, crural repair, and antireflux procedures were performed (72 Nissen, 27 Collis-Nissen). The 30-day death rate was zero; there was one surgery-related death at 5 months from a perioperative stroke. Intraoperative complications included pneumothorax, esophageal perforation, and gastric perforation. There were three conversions to open surgery. Major postoperative complications included stroke, myocardial infarction, pulmonary emboli, adult respiratory distress syndrome, and repeat operations (two for abscess and one each for hematoma, repair leak, and recurrent hernia). Median length of stay was 2 days. Median follow-up at 12 months revealed resumption of proton pump inhibitors in 10 patients and one repeat operation for recurrence. The mean heartburn score was 2.3 (0, best; 45, worst); the satisfaction score was 91%; physical and mental component summary scores were 49 and 54, respectively (normal, 50). CONCLUSION: This report represents the largest series to date of laparoscopic repair of giant PEH. In the authors' center with extensive experience in minimally invasive surgery, laparoscopic repair of giant PEH was successfully performed in 97% of patients, with a minimal complication rate, a 2-day length of stay, and good intermediate results.     

Outpatient laparoscopic sleeve gastrectomy: first 100 cases

Study objectiveThe development of outpatient surgery was one of the major goals of public health policy in 2010. The purpose of this observational prospective study was to evaluate the feasibility of laparoscopic sleeve gastrectomy (SG) in an ambulatory setting.DesignStudy design was a prospective prospective observational, nonrandomized study, registered (ClinicalTrials.gov identifier: NCT01513005), with institutional review board approval and written informed consent.SettingAmiens University Medical Center.PatientsPatients undergoing SG who were preselected by inclusion ambulatory criteria.InterventionsAll patients operated on for obesity by laparoscopic SG, from May 2011 through July 2013.MeasurementsWe collected outcomes data on 100 patients including incidence of postoperative nausea and vomiting, maximum and average pain scores, and the overall satisfaction rate.Main resultsOf the 100 obese patients, 93% were women. The mean age was 36 years (22-55 years). The mean preoperative body mass index was 42.4 kg/m². The mean operating time was 60 minutes (range, 30-95 minutes). The overall satisfaction rate was 93% (n = 93). When leaving the postoperative care unit, 94% of patients felt no or mild pain. Eighty-two percent had no postoperative postoperative nausea and vomiting, and 7 patients needed treatment using ondasetron.ConclusionsLaparoscopic SG in an ambulatory setting is feasible with a dedicated anesthesiological approach and an expert surgical team. Appropriate patient selection is important for ensuring safety and quality of care within the outpatient program.     

Laparoscopic cholecystectomy in children: lessons learned from the first 100 patients.

BACKGROUND/PURPOSE: Laparoscopic cholecystectomy is a very common operation in adults but is relatively infrequently required in children. A retrospective review of 100 consecutive infants and children undergoing laparoscopic cholecystectomies from 1990 to 1998 was performed to see what lessons have been learned from this relatively large population of pediatric patients. RESULTS: The patients ranged in age from 25 to 230 months, with a mean of 105 months. Only 19 patients had hemolytic disease as the etiology for their cholelithiasis. Two patients had biliary dyskinesia. Seventy-eight patients underwent an elective operation. Twenty-two children required urgent hospitalization because of complications from their cholelithiasis: acute cholecystitis (n = 7), jaundice and pain (n = 6), gallstone pancreatitis (n = 5), acute biliary colic (n = 4). All 6 patients who presented with jaundice underwent endoscopic retrograde cholangiopancreatography (ERCP) before their laparoscopic cholecystectomy. Two patients required laparoscopic choledochal exploration. The operating time and postoperative hospitalization were significantly longer (P = .0005) in the complicated group when compared with the elective patients. No significant complications such as the need for reoperation, injury to the choledocuhus or to other viscera, bile leak, or retained choledocholithiasis occurred. CONCLUSIONS: Laparoscopic cholecystectomy is a safe, effective procedure in children for removal of the gallbladder. The exact role of routine cholangiography and ERCP remains unclear.     

MICS CABG: a single-center experience of the first 100 cases

PurposeTo study the learning curve and outcomes of the first 100 cases of minimally invasive cardiac surgery (MICS) coronary artery bypass grafting (CABG) performed at our center.MethodsFrom January 2017 to November 2019, a total of 100 patients underwent CABG via left anterior thoracotomy approach. We have studied the operative times within the MICS CABG patients to analyze our learning curve. We also studied the postoperative outcomes and compared these with those of patients who underwent sternotomy during the same period.ResultsThe mean age was 59.33 ± 9.95 (range 37–82) years. The numbers of males and females were 72 and 28 respectively. The preoperative average ejection fraction (EF) was 51.08 ± 9.75%. All these patients underwent CABG via left thoracotomy approach, after satisfying the exclusion criteria. All patients received left internal mammary artery (LIMA) to left anterior descending (LAD) as a standard graft, with the radial artery and saphenous vein being the next alternative conduits. The average length of the incision was 6.06 ± 0.45 cm. Only 2 cases were done on pump. The average number of grafts per patient was 2.33 ± 0.92. The mean operative time was 132.40 ± 11.56 min. The mean duration of ventilation was 4.79 ± 1.90 h and average intensive care unit (ICU) stay was 2.62 ± 0.84 days. There was one conversion and no mortalities in our study. We had analyzed our operative times and noticed a significant reduction after the first 20 cases, which was our learning curve.ConclusionMICS CABG can be performed for multivessel disease with the same comfort as for a single or a double vessel disease, once the learning curve has been achieved. Only significant difference from the sternotomy approach was noted in the longer operative times for MICS CABG during the learning curve, and not thereafter. Significant benefits of MICS over sternotomy were noticed in the immediate postoperative parameters like duration of ventilation, mean drainage, postoperative pain, ICU stay, and hospital stay, with no difference in postoperative adverse events.     

Electra trapezio metacarpal prosthesis: results of the first 100 cases

The Elektra trapeziometacarpal prosthesis is a cementless, unconstrained prosthesis made by Fixano with titanium and chrome-cobalt steel. This paper examines the results of the first 100 prostheses used by the author for one indication only, viz. painful trapeziometacarpal osteoarthritis. The average follow-up period was 54 (range 36-78) months. Studies of pain, mobility and grip and pinch strength were carried out, the results of which were good in 83 cases. Seven dislocations occurred. Five of these were following severe trauma. The commonest complication was a lack of osteointegration of the trapezial part of the prosthesis, which occurred in 15 cases. Sinking into the metacarpal of the distal stem occurred early in the series in two cases. Some others complications were observed: allergy to the metal (one case), fracture after direct trauma of the thumb (one case) and very painful osteoarthritis of the scaphotrapeziotrapezoid joint (one case).     

Laparoscopic cholecystectomy. Apropos of 450 cases]

450 successive celioscopic cholecystectomies (May, 1990-April, 1992) are reported for 312 cases of uncomplicated gallstone (69%) operated electively and 138 cases operated in emergency, including 120 cases of acute cholecystitis, 17 cases of biliary pancreatitis and 1 case of angiocholitis. Immediate conversion into laparotomy was required in 10 cases (2.2%) either for technical reasons (1.1%) or because of lithiasis of the common bile duct (1.1%). The stay in hospital lasted an average of 2.2% days for elective admission and 3.3 days for emergent admission. The average operating time was 65 minutes (75 minutes until May, 1991, and 55 minutes between May, 1991 and April, 1992). Preoperative retrograde cholangiography was performed in 67 cases and intraoperative cholangiography in 16 cases. Second surgery was required for suture in one case because of cholerrhagia in a secondary duct of the gallbladder bed. This cholerrhagia would not have been amenable to simple aspiration. One patient (0.2%) died of myocardial infarction at D + 10. Complications include 4 cases of pulmonary embolism, 3 cases of cystic biliary fistula without second surgery and 4 cases of umbilical hernia. A more peculiar case is that of a patient admitted 5 months after surgery for gangrenous acute cholecystitis. This patient was admitted for fever and epigrastric pain. He had a very low-flow duodenocutaneous fistula of uncertain origin. This patient was not operated again. This may not be a complication connected to celioscopic surgery. Celioscopic cholecystectomy is superseding conventional cholecystectomy. Surgeons' efforts should strive at eliminating operative errors, reducing postoperative morbidity, improving techniques and instruments, teaching celioscopic surgery and extending its indications to other intraabdominal operations.     

Liver transplantation: experience with our first 100 cases

OBJECTIVES: Our goal was to evaluate the results of the first 100 liver transplants performed in our institution. METHODS: We retrospectively analyzed the first 100 liver transplants undertaken in adults from November 2001 to August 2005. RESULTS: The mean age of the recipients was 50 years (20 to 69) and 73% were men. The mean waiting time was 35 days. The mean age of the donors was 60 years (15 to 87), and 60% were men. One-year patient and graft survival rates were 93% and 90%, respectively. Three-year patient and graft survival rates were 85% and 82%, respectively. The need for retransplantation was 3%. Surgical complications included hepatic artery stenoses, 2%; hepatic artery thromboses, 2%; biliary leaks, 6%; and biliary stenoses, 14%. CONCLUSIONS: These results are no different from the overall results for liver transplantation in Spain during the same period.     

Surgery of atrioventricular septal defects. Review of the first 100 cases

From 1972 to 1985, the first 100 children suffering from some form of atrio-ventricular septal defect underwent surgical correction. In all cases, corrective surgery was carried out primarily except in 3 children who presented with a total defect and first underwent palliative surgery. In 48 children, a complete form was present, in 5 an intermediate form, and in 47 a partial form. There were 43 males and 57 females. Thirty-eight percent of patients suffered from Down's syndrome. The mean age at operation was 42 (range 2-143) months. A prosthesis was implanted in the left atrio-ventricular valve at primary correction in 9 patients. Up to 1980, the overall mortality was 20% and from 1981 to 1985 it was 3.3%. There was late mortality in 3 children (2 with a complete form and 1 partial). In 32 cases, postoperative cardiac catheterization was performed. Nine patients were reoperated upon (9%), 2 due to a residual shunt, 4 due to serious mitral incompetence (in all cases a prosthesis was used), and 3 due to valvular thrombosis. In this series, only 2 patients remained in complete atrio-ventricular block (1 affected by the complete form and the other partial). Long term survival is related to the severity of left valvular insufficiency. In this series with a mean follow-up of 3.83 +/- 2.78 years, we had an a cumulative survival of 86.7% +/- 3.43%. At the last control, most of the survivors had a good quality of life: 91% were in class I and 9% in class II according to the NYHA scale.     

Laparoscopic radical prostatectomy: minimum 3-year follow-up of the first 100 patients in the UK

OBJECTIVE: To present the results of the first 100 patients in the UK treated by laparoscopic radical prostatectomy (LRP) and with at least 3 years of follow-up, as LRP continues to develop as a minimally invasive alternative to open radical prostatectomy. PATIENTS AND METHODS: In all, 100 patients (mean age 62 years, range 52-72) had a transperitoneal LRP by one surgeon during a 25-month period from 2000 to 2002. Most (78%) patients had a prostate-specific antigen level of 4-10 ng/mL, clinical stage T1 disease (62%), and Gleason 6 on biopsy (50%). Sixty-four patients had unilateral or bilateral nerve preservation and 14 had pelvic lymphadenectomy. RESULTS: The mean operative duration was 245 min, with a 1% conversion rate. Three patients received a blood transfusion and three had major complications, including a rectal injury. The positive margin rate was 16% and correlated with pathological variables. At > or = 3 years of follow-up (mean 3.7) the overall survival rate was 99% and the biochemical progression-free survival was 88% in all patients, at 90% for pT2 and 75% for pT3. Ninety patients used 0-1 pads/day (84% pad-free) and 60 undergoing nerve preservation retained erectile function. CONCLUSION: This series includes the first results for LRP with a > or = 3-year follow-up reported from the UK, with oncological control and morbidity comparable to those in previously published open and laparoscopic series. The history of open radical prostatectomy suggests that as the technique of LRP develops and experience with it increases, these results are likely to improve.     

Anatomic Porous Replacement hip arthroplasty: first 100 consecutive cases

One hundred consecutive Anatomic Porous Replacement (Intermedics Orthopaedics, Austin, TX) hip replacements were followed for 4 years. Eighty percent of patients had bone ingrowth fixation, 14% stable fibrous, and 6% unstable fibrous (loose) with 4% revised. Only two hips changed fixation grade after 2 years. Bone remodeling showed cancellous hypertrophy of the cortex, usually along the lateral cortex, and 7% had stress shielding (atrophy) of the proximal cortices. Adaptive bone remodeling almost always occurred in type B and C bone. Bone remodeling was statistically related to bone type, prosthetic fill, stem-bone ratio, and collar loading. We concluded that proximal bone ingrowth fixation with proximal load transfer provides good clinical results and excellent bone remodeling. Also, collar loading improves bone response. To expand this fixation in a predictable fashion to all type B and some type C bone requires geometry changes, which have been accomplished in the Anatomic Porous Replacement II.     

Colonic perforation during colonoscopy. 100 cases]

The analysis of 100 cases of colon perforation during colposcopic examinations highly demonstrates such a statement. The perforation risk during colposcopies is generally of the order of 0.2% for a diagnosis coloscopy. According to the statistic data used, it can reach 0.5 to 3% in therapy coloscopy. This is a risk inherent to the technique used. It is thus required to analyse the causes and take the appropriate measures to reduce it to a minimum. Mortality due to such a complication remains high (14%), i.e about 0.015 to 0.1% (#2/10000) of all colposcopies. In 11% of the patients, serious sequelae are to be observed. This demonstrates the significance of the medico-legal problem set by these perforations during colposcopies. The whole personnel responsibility can be involved: colposcopist, surgeon, anesthetist and hospital unit.     

Pediatric robotic surgery: A single-institutional review of the first 100 consecutive cases

Background Robotic surgery is a new technology which may expand the variety of operations a surgeon can perform with minimally invasive techniques. We present a retrospective review of our first 100 consecutive robotic cases in children. Methods A three-arm robot was used with one camera arm and two instrument arms. Additional accessory ports were utilized as necessary. Two different attending surgeons performed the procedures. Results Twenty-four different types of procedures were completed using the robot. The majority of the procedures (89%) were abdominal procedures with 11% thoracic. No urology or cardiac procedures were performed. Age ranged from 1 day to 23 years with an average age of 8.4 years. Weight ranged from 2.2 to 103 kg with a median weight of 27.9 kg. Twenty-two patients were less than 10.0 kg. Examples of cases included gastrointestinal (GI) surgery, hepatobiliary, surgical oncology, and congenital anomalies. The overall majority of cases had never been performed minimally invasively by the authors. The overall intraoperative conversion rate to open surgery was 13%. One case (1%) was converted to thoracoscopic because of lack of domain for the articulating instruments. No conversions or complications occurred as a result of injuries from the robotic instruments. Interestingly, four abdominal cases were converted to open surgery due to equipment failures or injuries from standard laparoscopic instruments used through non-robotic accessory ports. Conclusions Robotic surgery is safe and effective in children. An enormous variety of cases can be safely performed including complex cases in neonates and small children. Simple operations such as cholecystectomies have minimal advantages by using robotic technology but can serve as excellent teaching tools for residents and newcomers to this form of minimally invasive surgery (MIS). The technology is ideal for complex hepatobiliary cases and thoracic surgery, particularly solid chest masses. This paper has been accepted for presentation at the SAGES meeting in Las Vegas, NV April 16^th–22^nd, 2007. (SEND-07-0145)
