Is laparoscopic antireflux surgery for gastroesophageal reflux disease in the elderly safe and effective?

Background: The elderly have prevalence rates and clinical features of gastroesophageal reflux disease (GERD) similar to those in younger individuals, but the role of laparoscopic antireflux surgery (LARS) in the elderly has not been clearly established. The purpose of this study was to determine if the results of LARS in the elderly are comparable with those in younger patients. Methods: All patients undergoing LARS for GERD at the Washington University Medical Center were entered prospectively into a computerized database. Between May 1992 and June 1998, 339 patients underwent LARS and were divided into two groups based on age: nonelderly (ages, 18–64 years; n= 303) and elderly (age, ≥65 years; n = 36). Data were expressed as mean ± standard deviation (SD) and statistical analysis was performed. Results: Elderly patients had a higher American Society of Anesthesiology (ASA) score (2.3 ± 1.5) and a longer hospital stay (2.1 ± 0.2 days) than the younger group (ASA, 1.9 ± 0.5; hospital stay, 1.6 ± 0.9 days; p < 0.001). Operation times averaged 154 ± 68 min in the elderly compared with 134 ± 49 min in the nonelderly (p= NS). Grade I complications occurred significantly more frequently in the elderly (13.9%) than in the nonelderly (2.6%), but the incidence of grade II complications was similar between the groups (elderly 2.8% vs nonelderly 2.7%). There were no grade III complications in either group, but there was one death in the nonelderly group. At follow-up ranging to 81 months (median, 27 months), the two groups had similar low incidences of heartburn and dysphagia. Anatomic failures of LARS developed in 19 nonelderly patients (6.2%) compared with 2 elderly patients (5.5%; p= NS). Conclusions: As shown in this study, LARS is safe and effective in elderly patients with GERD. Age older than 65 years should not be a contraindication to laparoscopic antireflux surgery in properly selected patients. Received: 3 March 1999/Accepted: 2 April 1999     

Laparoscopic esophagomyotomy with posterior partial fundoplication for primary esophageal motility disorders

Background: The outcomes of a laparoscopic esophagomyotomy with posterior partial fundoplication were compared between groups of patients with primary motility disorders. Methods: In this study, 47 patients (26 women and 21 men, ages 24 to 77 years; mean, 47 years) with significant dysphagia or chest pain who failed conservative treatment underwent a laparoscopic esophagomyotomy and posterior partial fundoplication. Preoperative evaluation revealed four groups of primary motility disorders: achalasia (n= 12), nutcracker esophagus (n= 12), hypertensive lower esophageal sphincter (LES) (n= 16), and diffuse esophageal spasm (n= 7). Statistical analysis was performed by Cramer's V test. Results: Average follow-up period was 30.3 months. There was no mortality or early morbidity. Late morbidity included dysphagia or chest pain over 6 weeks in 10 patients (21%), recurrent gastroesophageal reflux disease (GERD) in 3 patients (6%), and recurrent motility disorder in 2 patients (4%). Overall, 94% of the patients ultimately had complete resolution of dysphagia or chest pain. There was no significant difference in outcomes between groups. Conclusion: Early results suggest that laparoscopic esophagomyotomy with posterior partial fundoplication provides safe and effective relief from dysphagia and chest pain in patients with each of the primary motility disorders.

360° laparoscopic fundoplication with tension-free hiatoplasty in the treatment of symptomatic gastroesophageal reflux disease

Background: Since laparoscopic Nissen fundoplication was first described by Cuschieri in 1989 and later by Dallemagne in 1991, this procedure has been widely employed for the treatment of symptomatic gastroesophageal reflux disease (GERD) and/or hiatal hernia. However, a relatively high incidence (7–11%) of intrathoracic Nissen valve migration/paraesophageal hernia following laparoscopic fundoplication has recently been reported. Methods: Between November 1992 and August 1995, 65 consecutive patients with severe GERD and/or hiatal hernia underwent laparoscopic 360° fundoplication. In nine of these 65 (13.8%) patients, an intrathoracic Nissen valve migration had occurred within 4 months. Six of these patients were symptomatic and were again submitted to the laparoscopic intervention. Videotapes of both the first and second operation were reviewed. In all cases, it was apparent that, at the first operation, closure by stitches of the hiatus was under tension, and at the second operation, the muscle fibers of the right crus were disrupted, probably due to the tension between the suture margins during the inspiratory movements of the diaphragm. These findings prompted us to perform an effective tension-free closure of the hiatus. A polypropylene mesh (3 × 4 cm) was placed on the hiatus behind the esophagus and fixed with eight metallic agraphes (2 + 2 on the superior edge and 2 + 2 on the lateral sides of the right and left cruses). Results: Between August 1995 and February 1998, the technique, complete with 360° fundoplication, was used for 67 patients with GERD. At mean follow-up of 22.5 months (range, 1–30), there was no evidence of postoperative paraesophageal hernia or complications related to the use of the mesh. Conclusions: This tension-free hiatoplasty seems to be an effective solution to prevent postoperative paraesophageal hernia in patients undergoing antireflux laparoscopic surgery. However, longer follow-up is still needed. Received: 9 July 1998/Accepted: 19 April 1999     

Prevalence of gastroesophageal reflux after laparoscopic Heller myotomy

Background: There is still some controversy over the need for antireflux procedures with Heller myotomy in the treatment of achalasia. This study was undertaken in an effort to clarify this question. Methods: To determine whether Heller myotomy alone would cause significant gastroesophageal reflux (GER), we studied 16 patients who had undergone laparoscopic Heller myotomy without concomitant antireflux procedures. Patients were asked to return for esophageal manometry and 24-h pH studies after giving informed consent for the Institutional Review Board (IRB)-approved study at a median follow-up time of 8.3 months (range, 3–51). Results are expressed as the mean ± SEM. Results: Fourteen of the 16 patients reported good to excellent relief of dysphagia after myotomy. They were subsequently studied with a 24-h pH probe and esophageal manometry. These 14 patients had a significant fall in lower esophageal sphincter (LES) pressure from 41.4 ± 4.2 mmHg to 14.2 ± 1.3 mmHg, after the myotomy (p < 0.01, Student's t-test). The two patients who reported more dysphagia postoperatively had LES pressures of 20 and 25 mmHg, respectively. Two of 14 patients had DeMeester scores of >22 (scores = 61.8, 29.4), while only one patient had a pathologic total time of reflux (percent time of reflux, 8%). The mean percent time of reflux in the other 13 patients was 1.9 ± 0.6% (range, 0.1–4%), and the mean DeMeester score was 11.7 ± 4.6 (range, 0.48–19.7). Conclusions: Laparoscopic Heller myotomy is effective for the relief of dysphagia in achalasia if the myotomy lowers the LES pressure to <17 mmHg. If performed without dissection of the entire esophagus, the laparoscopic Heller myotomy does not create significant GER in the postoperative period. Clearance of acid refluxate from the aperistaltic esophagus is an important component of the pathologic gastroesophageal reflux disease (GERD) seen after Heller myotomy for achalasia. Furthermore, GERD symptoms do not correlate with objective measurement of GE reflux in patients with achalasia. Objective measurement of GERD with 24 h pH probes may be indicated to identify those patients with pathologic acid reflux who need additional medical treatment.

Laparoscopic gastro- and hepaticojejunostomy for palliation of pancreatic cancer

Background: Most patients presenting with pancreatic cancer are irresectable at the time the diagnosis is made. Therefore, they are in need of palliative treatment that can guarantee minimal morbidity, mortality, and hospital stay. To address this need, we designed a study to test the feasibility of laparoscopic gastroenterostomy and hepaticojejunostomy and to compare their results with those achieved with open techniques. Methods: We performed a case control study of a new concept in laparoscopic palliation based on the findings of preoperative imaging and diagnostic laparoscopy. Laparoscopic side-to-side gastroenterostomy and end-to-side hepaticojejunostomy (Roux-en-Y) were done in irresectable cases. Of 14 patients who underwent laparoscopic palliation, three had a laparoscopic double bypass, seven had a gastroenterostomy, and four underwent staging laparoscopy only. The results were compared with a population of 14 matched patients who had conventional palliative procedures. Results: Postoperative morbidity was 7% vs 43% for laparoscopic and open palliation, respectively (p < 0.05). There were no mortalities in the laparoscopic group, as compared to 29% in the group who had open bypass surgery (p < 0.05). Postoperative hospital stay averaged 9 days in the laparoscopic group and 21 days in the open group (p < 0.06). Operating time tended to be shorter in the laparoscopic group (p < 0.25). Morphine derivatives were necessary for a significantly shorter period after laparoscopic surgery (p < 0.03). Conclusions: Our preliminary experience strongly suggests that laparoscopic palliation can reduce the three major drawbacks of open bypass surgery—i.e., high morbidity, high mortality, and long hospital stay.

Laparoscopic secondary antireflux procedure after PEG placement in children

Background: This study investigates the feasibility of performing a subsequent laparoscopic antireflux procedure after former placement of a percutaneous endoscopic gastrostomy (PEG). Methods: Between 1997 and 1998, five patients with a gastrostomy in place presented with an indication for laparoscopic antireflux procedure due to persisting vomiting. Results: All patients were managed laparoscopically with a four-trocar technique. Conclusions: Primary PEG placement has no adverse effects on a later secondary antireflux procedure. In some cases, four rather than five trocars can be used. Received: 7 December 1999/Accepted: 7 March 2000/Online publication: 29 August 2000     

A simplified approach to laparoscopic fundoplication

Background: There is a certain amount of controversy regarding the need to divide the short gastric vessels (SGV) in laparoscopic fundoplication for treatment of gastroesophageal reflux disease (GERD). In addition, there is often difficulty in identifying the crural fibers when encircling the lower esophagus. Methods: We determine whether it is necessary to divide the SGV by trying to appose the gastric fundus to the anterior abdominal wall intraoperatively. If this could be done easily, the SGV are preserved. When their division is required, a posterior gastric approach is employed. We have also found that the injection of methylene blue into the left crural fibers anterior to the esophagus is helpful in identifying the left side when dissection posterior to the gastroesophageal junction is difficult. Results: Between 1992 and 1995 we performed 20 laparoscopic fundoplications for GERD. All patients had at least grade 3 esophagitis (Savary-Miller scale), increased esophageal exposure to acid (median DeMeester score of 195), and decreased lower esophageal sphincter (LES) pressure. The median operative time was 175 min. There were no conversions to open surgery, and there was no mortality. Three patients developed transient postoperative dysphagia and one patient had pneumonia. The median hospital stay was 3 days; all patients were free of reflux symptoms at follow-up ranging from 7 to 42 months. Conclusion: We conclude that the techniques described by us aid in intraoperative decision making and allow laparoscopic fundoplication to be both simple and effective.

Short-stay laparoscopic adrenalectomy

Background: We performed a consecutive series of unilateral laparoscopic adrenalectomies (LA) with the expectation of short (less than 24 h) hospital stay. Results were compared with those from laparoscopic cholecystectomy (LC) and unilateral open adrenalectomy (OA). Methods: A combination of chart review and patient questionnaires was used to compare LA (n= 19) to LC (n= 20) regarding length of stay (LOS), narcotic requirements, and time to full recovery. Chart reviews also were used to compare LA to OA (n= 48) regarding operating room time (OR time), LOS, and surgical morbidity. Results: All of the LC patients as compared with 47% of the LA patients were discharged within 24 h. The reason for additional hospitalization in the LA group was pain control. After discharge, the narcotic requirement lasted 6.6 days in the LA group as compared with 3.4 days in the LC group (p < 0.01), but the times until full recovery were not significantly different (12.2 vs 11.3 days respectively). Operating room times did not differ significantly between the LA and OA groups (3.3 and 3.8 h, respectively), but there were fewer postoperative complications and much shorter LOS in the LA group (1.5 vs 6.3 days; p < 0.001), a difference that remained significant even when cases from the same time period were compared. Conclusions: Increased pain in LA as compared with LC patients may result in a slightly longer LOS and higher narcotic requirement during the early postoperative period, but time to full recovery between the two groups is the same. As compared with its open counterpart, LA offers a significant reduction in LOS and morbidity with no increase in OR time.

Laparoscopic vs open colectomy for sigmoid diverticulitis

Background: The aim of this prospective comparative study was to assess the outcome of laparoscopic and open colectomy for sigmoid diverticulitis in patients aged ≥75 years. Methods: From January 1993 to December 1998, all patients 75 years of age and older undergoing an elective colectomy for sigmoid diverticulitis were included in the study. The patients were divided into the following two groups: group 1 (n= 22) consisted of patients who underwent a laparoscopic procedure; group 2 (n= 24) consisted of patients who underwent an open procedure. Results: In group 1, there were 12 women and 10 men with a mean age of 77.2 years (range, 75–82); in group 2, there were 14 women and 10 men with a mean age of 78 years (range, 76–84) (p= 0.37). There was no difference between the groups in ASA classification. The operative time was shorter in group 2 (136 vs 234 mins). The postoperative period during which parenteral analgesics were required (5.4 vs 8.2 days, p= 0.001), postoperative morbidity (18% vs 50%, p= 0.02), postoperative length of hospital stay (13.1 vs 20.2 days, p= 0.003), and the inpatient rehabilitation (6 vs 15 patients, p= 0.01) were significantly shorter for group 1 than for group 2. There were no perioperative deaths. The conversion rate was 9% in group 1. Conclusion: The data from the present study suggest that laparoscopic colectomy for sigmoid diverticulitis can be applied safely to older patients with fewer complication, less pain, shorter hospital stay, and a more rapid return to preoperative activity levels than that seen with open colorectal resection.

Laparoscopic Heller myotomy relieves dysphagia in achalasia when the esophagus is dilated

Background: It has been said that a Heller myotomy cannot improve dysphagia in achalasia when the esophagus is markedly dilated or sigmoid shaped. Those who hold this belief recommend esophagectomy as the primary treatment in such cases. This study aimed to compare the results of laparoscopic Heller myotomy combined with Dor fundoplication in 66 patients with and without esophageal dilatation, all of whom had achalasia. Methods: On the basis of the maximal diameter of the esophageal lumen and the shape of the esophagus, the patients were placed into four groups: group A (esophageal diameter <4.0 cm; 26 patients), group B (diameter 4.0–6.0 cm; 21 patients), group C1 (diameter >6.0 cm and straight esophageal axis; 12 patients), and group C2 (diameter >6.0 cm and sigmoid-shaped esophagus; 7 patients). All patients underwent a laparoscopic Heller myotomy and Dor fundoplication. Results: The duration of the operation and the length of hospital stay were similar among the four groups. Excellent or good results were obtained in 88% of group A, 100% of group B, 83% of group C1, and 100% of group C2. No patient in this consecutive series ultimately required an esophagectomy. Conclusions: In patients with achalasia who have esophageal dilation, a laparoscopic Heller myotomy and Dor fundoplication (a) took no longer and was no more difficult, (b) was associated with no more postoperative complications, and (c) gave just as good relief of dysphagia. We conclude that esophageal dilation by itself should rarely serve as an indication for esophagectomy rather than myotomy as the initial surgical treatment.

Laparoscopic fundoplication to enhance pulmonary function in children with severe reactive airway disease and gastroesopheagal reflux disease

Background: The relationship between severe reactive airway disease (RAD) and gastroesophageal reflux disease (GERD) has been noted but the relationship is poorly understood. This study reports our experience with laparoscopic fundoplication and it's effect on the pulmonary status of children with severe steroid-dependent reactive airway disease. Methods: Fifty-six patients with severe steroid-dependent RAD and medically refractory GERD underwent laparoscopic Nissen fundoplications. Mean age was 7 years and mean weight was 20 kg. All patients had the procedure completed successfully laparoscopically with an average operative time of 62 min. Average hospital stay was 1.6 days. Results: Forty-eight of 56 patients noted significant improvement in their respiratory symptoms in the first week. Fifty of 56 patients have been weaned off their oral steroids and four others have had a greater than 50% decrease in their dose. Sixteen patients had a documented increase in their FEV1 in the initial postoperative period (avg. 26%). Conclusion: Patients with steroid-dependent RAD and GERD refractory to medical management show improvement in their respiratory status following fundoplication and the majority can be weaned off of their oral steroids. Laparoscopic techniques allow this procedure to be performed safely even in this high-risk group of patients. Received: 25 March 1997/Accepted: 5 July 1997     

A comparison of laparoscopic Nissen fundoplication and Rossetti's modification in 239 patients

Background: Laparoscopic Nissen fundoplication and the Rossetti modification represent two different surgical approaches to resolving gastroesophageal reflux disease (GERD). Concerns have arisen that the Rossetti modification results in increased postoperative dysphagia. In this study, we compared a group of patients who underwent a laparoscopic Nissen fundoplication with a group who had undergone the Rossetti modification to determine if there was a significant difference in postoperative dysphagia. Additionally, we wanted to confirm that the Nissen procedure performed laparoscopically could resolve GERD as successfully as the Rossetti modification, with no difference in operative complications. Methods: We prospectively collected data on 101 patients who underwent laparoscopic Nissen fundoplication and compared outcomes with those of 138 patients who had undergone the laparoscopic Rossetti modification in a previous series. Results: All patients experienced resolution of reflux symptoms. No statistically significant differences were found between the groups in terms of intraoperative or postoperative complications, conversions to open procedure, or length of hospitalization. Paradoxically, there was a significant difference in operating time between the Rossetti and the Nissen groups (70.6 min vs 45.6 min, p= 0.006). Postoperative dysphagia requiring dilation was significantly higher in the Rossetti group (21.7% vs 8.9%, p= 0.008). However, there was a significantly higher percentage of patients in the Rossetti group who had had esophagitis preoperatively (95.7% vs 86.1%, p= 0.009), although the proportion of patients having Barrett's esophagus was higher in the Nissen group (9.4% vs 24.8%, p= 0.001). Conclusions: Both approaches resolved reflux symptoms without significant differences in complications, conversions, or length of stay. Preoperative differences between groups, as well as the method of sequentially comparing the two different procedures, prevent us from attributing greater postoperative dysphagia in the Rossetti group solely to the choice of surgical approach. Prospective randomized studies are needed to control for variables, such as surgical team experience and patient differences. Online publication: 17 April 2000     

Impact of hematological diagnosis on early and late outcome after laparoscopic splenectomyrid=""

Background: Laparoscopic splenectomy (LS) is now regarded as the treatment of choice for autoimmune thrombopenia (ITP). However, there have been few reports describing the application of LS to other splenic diseases, such as malignant entities and conditions associated with splenomegaly. Hematological diseases have specific clinical features that can influence immediate outcome after LS. Although the long-term effects of LS are unknown, a risk of splenosis has been suggested. Therefore, we designed a study to analyze the impact of primary hematological disease on immediate and late outcome in a prospective series of LS patients. Methods: We performed a prospective analysis of 111 LS done between February 1993 and March 1999. The patients were classified by hematological indications into the following four groups: (a) group 1, low platelet count. This group was further subdivided into group 1A, idiopathic thrombocytopenic purpura (ITP) (n= 48) and group 1B, HIV-related ITP (n= 8); (b) group 2, anemia. This group was further subdivided into group 2A, autoimmune hemolytic anemia (n= 8), and group 2B, spherocytosis (n= 11); (c) group 3, malignancy (n= 28); and (d) group 4, others (n= 8). Immediate outcomes were recorded prospectively. Hematological status and late complications were reviewed after a mean follow-up of 24 ± 18 months. Results: There were no significant differences between the groups in terms of conversion, transfusion requirements, and morbidity, although transfusion and morbidity were slightly higher in group 3. However, hospital stay was significantly longer in groups 3 and 4 than in groups 1 and 2. Long-term follow-up showed satisfactory hematological results in ≥75% of patients (group 1A, 82%; group 1B, 88%; group 2A, 88%; group 2B, 100%; group 3, 75%; group 4, 88%). Overall, late morbidity was 8.3% and mortality was 6.2%, mainly due to deaths in group 4 (six of 22 patients). Conclusion: LS is a safe and reproducible procedure for most hematological indications, with a similar immediate outcome for benign diseases and a long-term hematological response comparable to the standard results that have been observed in open series.

Laparoscopic repair of large hiatal hernia with polytetrafluoroethylene

Background: Several studies have shown that large hiatal hernias are associated with a high recurrence rate. Despite the problem of recurrence, the technique of hiatal herniorrhaphy has not changed appreciably since its inception. In this 3-year study we have evaluated laparoscopic hiatal hernia repair in individuals with a hernia defect greater than 8 cm in diameter. Methods: A series of 35 patients with sliding or paraesophageal hiatal hernias was prospectively randomized to hiatal hernia repair with (n= 17) or without (n= 18) polytetrafluoroethylene (PTFE). All patients had an endoscopic and radiographic diagnosis of large hiatal hernia. Both repairs were performed by using interrupted stitches to approximate the crurae. In the group randomized to repair with prosthesis, PTFE mesh with a 3-cm ``keyhole' was positioned around the gastroesophageal junction with the esophagus through the keyhole. The PTFE was stapled to the diaphragm and crura with a hernia stapler. Results: Patients were followed with EGD and esophagogram at 3 months postoperatively, and with esophagogram every 6 months thereafter. Individuals with PTFE had a longer operation time, but the 2-day hospital stay was the same in both groups. The cost of the repair was $1050 ± $135 more in the group with the prosthesis. There were two complications (1 pneumonia, 1 urinary retention) in the group repaired with PTFE and one complication (pneumothorax) in the group without prosthesis. The group without PTFE was notable for three (16.7%) recurrences within the first 6 months of surgery. Conclusion: On the basis of these preliminary results it appears that repair with PTFE may confer an advantage, with lower rates of recurrence in patients with large hiatal hernia defects.

A prospective multicenter study on laparoscopic treatment of gastroesophageal reflux disease in Italy

Background: A national survey was undertaken by the Italian Society for Laparoscopic Surgery to investigate the prevalence, indications, conversion rate, mortality, morbidity, and early results of laparoscopic antireflux surgery. Methods: Beginning on January 1, 1996, all of the centers taking part in this study were asked to complete a questionnaire on each patient. The questionnaire was divided into four parts and covered such areas as indications for surgery and preoperative workup, type of operation performed and certain aspects of the surgical technique, conversions and their causes, intraoperative and postoperative complications (within 4 weeks), and details of the postoperative course. The last part of the questionnaire focused on the follow-up period and was designed to gather data on recurrence of preoperative symptoms, postoperative symptoms (dysphagia, gas bloat), and postoperative test findings. Results: As of June 30 1998, 21 centers were taking part in the study and 621 patients were enrolled, with a median of 27 patients per center (less than one patient/month). The most popular technique was the Nissen-Rossetti (52%), followed by the Nissen (33%) and Toupet procedures (13%). Other techniques, such as the Dor and Lortat-Jacob, were used in the remainder of cases. Patients who received a Toupet procedure had a higher incidence of defective peristalsis (p < 0.05). The conversion rate to open surgery was 2.9%. The most common causes of conversion were inability to reduce the hiatus hernia or distal esophagus in the abdomen and adhesions from previous surgery. Perforation of the stomach and esophagus occurred in <1% of patients. Mortality was nil. Postoperative complications were observed in 7.3% of cases. The most common complication was acute dysphagia (19 patients), which required reoperation in 10 patients. No differences in the incidence of acute dysphagia were found for the different surgical techniques employed. Follow-up data were obtained for 319 patients (53%): 91.5% of the patients remained GERD symptom–free; severe esophagitis (grade 2–3) healed in 95% of the patients; lower esophageal sphincter (LES) manometric characteristics (pressure, abdominal length, and overall length) improved significantly after surgery (p < 0.005); and acid exposure of the distal esophagus decreased. Conclusions: Laparoscopic antireflux surgery has no mortality and a low morbidity. Symptoms and esophagitis are resolved in >90% of patients. Despite these favorable results, however, this type of surgery is not yet as widely employed in Italy as in other countries. Received: 12 February 1999/Accepted: 8 June 1999     

Iatrogenic thoracic migration of the stomach complicating laparoscopic Nissen fundoplication

Background: Intrathoracic gastric herniation after laparoscopic Nissen fundoplication is an uncommon but potentially life-threatening complication that may present in the early or late postoperative period. Methods: A retrospective analysis was performed on all patients undergoing antireflux surgery from December 1991 to June 1999. Results: Nine cases of gastric herniation occurred after 511 operations (0.17%). Patients presented with the condition 4 days to 29 months after surgery. Eight of these nine patients (89%) had reported vomiting in the immediate postoperative period. Seven patients (78%) reported persistent odynophagia. A factor common to all patients was that posterior crural repair had not been performed. Conclusions: Measures should be undertaken to prevent postoperative vomiting after laparoscopic Nissen fundoplication. Posterior crural repair is essential after surgery in all cases.

Laparoscopically assisted bowel surgery for inflammatory bowel disease

Background: Laparoscopic bowel surgery was evaluated in 44 consecutive patients who underwent surgery for inflammatory bowel disease (IBD). We studied feasibility, results, and final outcome. Methods: At two academic institutes, 44 laparoscopically assisted colectomies and laparoscopic ileostomies or colostomies were attempted. All patients had histologically proven IBD and no prior surgery for IBD. Loop ileostomy (n= 4), end colostomy (n= 1), ileocecal resection (n= 26) and (procto)colectomy (n= 13) were performed. All resections were laparoscopically assisted with extracorporal resection and anastomosis. Results: Only in two patients (ileocecal resection in both) was conversion to open surgery necessary. Two patients with laparoscopic ileocolic resection had intra-abdominal abscesses, which were drained percutaneously in both. One patient in the laparoscopically assisted colectomy group had a subphrenic abscess that was drained percutaneously, and one patient had a generalized candidiasis. Conclusions: Laparoscopically assisted colectomies can be performed safely in treating IBD. The laparoscopic method with use of a small vertical umbilical or Pfannenstiel's incision seems acceptable with regard to operating time and overall costs, also allowing superior cosmesis to be maintained.

Laparoscopic gastrojejunostomy and endoscopic biliary stent placement for palliation of incurable gastric outlet obstruction with cholestasis

Background: For patients with incurable malignant gastric outlet obstruction and cholestasis, laparoscopic gastrojejunostomy combined with endoscopic biliary stent placement seems to offer a minimally invasive palliation. Methods: We retrospectively analyzed the data of 16 patients submitted to laparoscopic gastrojejunostomy. Laparoscopic gastroenterostomy was performed as an antecolic, side-to-side gastrojejunostomy with enteroenterostomy. In 12 patients cholestasis was relieved preoperatively by stent placement via endoscopy (n= 6, 37.5%), percutaneous access (n= 5, 31%) or bilioenteric anastomosis (n= 1, 6.25%). One patient needed a percutaneous Yamakawa prosthesis postoperatively. Results: Mean operative time was 126 min. There were no intraoperative complications. In one patient conversion to open surgery became necessary because of extensive adhesions. The only postoperative complication was bleeding from a trocar site requiring reintervention; there was no mortality. Median postoperative hospital stay was 7 days. Delayed gastric emptying was observed in 3 (18.7%) patients. Median survival was 87 days after the operation. All patients died from their primary disease but could maintain oral intake during the remaining survival time. Conclusions: We conclude that laparoscopic gastrojejunostomy and endoscopic or percutaneous biliary stenting provide a good functional result while impairing the quality of life only to a minimal extent.

A combined laparoscopic-endoscopic method of assessment to prevent the complications of short esophagus

As antireflux surgery has been used increasingly for gastroesophageal reflux disease (GERD), a need has arisen for an accurate method to assess esophageal length. There are a number of preoperative tests that can help surgeons to establish the presence of a short esophagus, but intraoperative assessment after esophageal mobilization is the standard method. In this era of laparoscopic surgery, the surgeon mobilizes the esophagus extensively from the abdomen and then determines if mobilization is sufficient. We report an intraoperative technique that combines laparoscopic with endoscopic methods to determine the position of the gastroesophageal junction. Because two physicians are required, there is additional operating room time, resulting in increased costs. However, these costs are offset by the assurance that the complications of the short esophagus can be avoided. With experience, modifications were made, resulting in the technique described herein.

Multicentric experience of the Belgian Group for Endoscopic Surgery (BGES) with endoscopic adrenalectomy

Background: Adrenalectomy is not a frequent operation. Therefore the newly developed laparoscopic approach is sporadically performed by surgeons dealing with endocrine disorders. Methods: Some 54 videoendoscopic adrenalectomies performed on 52 patients by five surgical teams between October 1993 and December 1996 were prospectively evaluated. Results: Indications for endoscopic adrenalectomy were pheochromocytoma (n= 17), primary hyperaldosteronism (n= 15), Cushing's adenoma or disease (n= 7), nonsecreting adenoma (n= 7), single metastasis from adenocarcinoma (n= 2), adenoma with dehydroepiandrostenedione (DHEAS) hypersecretion (n= 3), and ACTH-secreting metastases from a thymoma (n= 1). Of the 54 adrenalectomies performed, 31 were of the left gland, 19 of the right and two bilateral. Laparoscopic adrenalectomy was successful in 50 patients (96%). Median tumor size was 4 cm (range 1.5–12), median operation duration was 80 min (range 59–360), and median postoperative stay was 4 days (range 2–13). One patient required blood transfusion. Conclusions: Endoscopic adrenalectomy can safely be performed—even sporadically—by surgeons well versed in adrenalectomy techniques for endocrine disorders and trained in endoscopic surgery.
