RESUMEN
This study aimed to evaluate outcome after liver resection for intrahepatic cholangiocarcinoma (ICC). In a 72-month period a total of 25 patients operated on for ICC were followed-up with postoperatively. Eleven right hemihepatectomies (8 extended), seven left hemihepatectomies (3 extended), one segmental resection, two bisegmentectomies (II + III), and four nonanatomical resections were performed. Median observation period was 2.7 (range: 0.2-6.9) years. Analysis focused on age, gender, tumor-size, operating time, histologic resection margin, Tumor-Node-Metastasis-stage, reoperations, postoperative complications, tumor recurrence, survival rate and a putative relation between p53 accumulation, ki67 index, MUC1 positivity, and prognosis. Mean tumor size was 6.49 +/- 3.93 cm. Eighteen patients (72%) underwent lymph node dissection. Major postoperative complications occurred in 10 patients. Seventeen patients (68%) showed tumor recurrence. Mean time to tumor recurrence was 6.7 (5.7-15.4) months. We found no correlation between p53 accumulation/ki67 index counts/Mucin 1 cell surface associated antibody (MUC1) positivity and ICC prognosis. A total of 13 patients died (52%) including one early and 12 late deaths. Mean time from surgery to death was 14.6 (7.4-30.9) months. Survival rate at 1 year was 84 per cent, at 3 years 57 per cent, and at 5 years 45 per cent. In our review only a small number of these 25 patients are indeed cured.

STUDY DESIGN: Case report. OBJECTIVE: A retroperitoneal lymphocele is a very rare complication associated with anterior lumbar interbody fusion surgery. SUMMARY OF BACKGROUND DATA: We report the diagnosis and management of 3 retroperitoneal lymphoceles, which occurred after anterior left retroperitoneal approaches for lumbar interbody fusion. METHODS: As the radiologic examinations revealed the lymphoceles in all 3 cases laparoscopic fenestration was performed. RESULTS: The patients had good recovery and no recurrence of the lymphoceles occurred. CONCLUSIONS: If this rare complication occurs the primary intervention should be laparoscopic fenestration because of the high recurrence rate of other treatment modalities.

BACKGROUND: When gastric banding was introduced as a bariatric operation about 12 years previously, its early results were promising, with a low complication rate. Only a few long-term studies on this subject have been published. This study was performed to assess our results with laparoscopic gastric banding in young patients afterAsunto(s)

RESUMEN
BACKGROUND: The aim of our study was to evaluate the use of intraoperative colonoscopy in laparoscopically assisted left-sided colon resection for the assessment of anastomosis. MATERIALS AND METHODS: All consecutive laparoscopically assisted left-sided colon resections performed at our department between May 2001 and February 2006 were included in this study. After colon resection and reanastomosis, an intraoperative colonoscopy was performed to detect anastomosis risk. RESULTS: A total of 122 patients were enrolled in this study. In 73 patients (59.84%), the anastomosis was checked via colonoscopy (the study group, (SG), whereas the control group (CG) consisted of 49 (40.16%) patients without colonoscopy. Of the 122 patients, 65 (53.28%) underwent a laparoscopically assisted sigmoid resection, 45 (36.89%) a laparoscopically assisted sigmoid rectum resection, 4 (3.28%) a laparoscopically assisted anterior rectum resection, and 8 (6.56%) a laparoscopically assisted left hemicolectomy. In the study group, 5 (6.85%) anastomotic leakages were intraoperatively detected and oversewn. A total of 6 (4.92%) anastomotic leakages occurred in the early postoperative period (SG: 4 [5.47%] vs. CG: 2 [4.08%]; P = 0.541). CONCLUSIONS: Intraoperative evaluation of anastomosis prevents early anastomotic insufficiency because intraoperative identification of leaks allows for repair during surgery. Nevertheless, a certain rate of anastomotic dehiscence occurs in every kind of colon resection. The sometimes increased rate of dehiscence in laparoscopic-assisted colon resection can be reduced by intraoperative colonoscopy.

BACKGROUND: The purpose of our study was to assess anal function in professional mountain bikers, as an increasing number of cycling enthusiasts report functional and morphological problems in the anal region. We tried to find out if constant saddle vibration suffered by professional cyclists could lead to defecation disorders. METHODS: 19 professional male mountain bikers took part in this study. The findings were compared with those of a control group (CG) of healthy volunteers who rode bikes less frequently. Both groups underwent rectal examination and anorectal manometry. Rectal sensation, rectal compliance and the anorectal inhibitory reflex were also assessed. Information on anal pain, blood on the toilet tissue, history of hemorrhoids, anal fissure, abscess formation and problems with defecation was collected by questionnaire and local examination was carried out. RESULTS: Sphincter resting pressures (89 +/- 27 mmHg vs CG: 69 +/- 16 mmHg), squeeze pressures (137 +/- 36 mmHg vs CG: 96 +/- 19 mmHg) and sphincter volumes (resting vector volume: 513 +/- 277 cc vs CG 273 +/- 170 cc, squeeze vector volume: 1389 +/- 867 cc vs CG: 490 +/- 219 cc) were significantly higher in the professional mountain bikers. Values reflecting rectal sensation (sensory threshold: 51 +/- 32 ml vs CG: 46 +/- 12 ml) were not significantly different between the groups. CONCLUSION: Proctological problems are very common in professional mountain bikers. Permanent microtrauma through constant saddle vibration may lead to chronic inflammation and anal fissure resulting in anal pain and therefore high sphincter pressure. Muscle hypertrophy as a consequence may lead to defecation disorders.

HYPOTHESIS: Preexisting gastroesophageal reflux disease (GERD) and esophageal motility disorders may affect the outcome of laparoscopic adjustable gastric banding (AGB). DESIGN: Prospective cohort study. SETTING: Tertiary referral center. PATIENTS: Between January 1, 1996, and December 31, 2002, AGB procedures were performed in 587 patients (mean body mass index, 46.7 [calculated as weight in kilograms divided by the square of height in meters]). The study population was composed of patients with preoperative GERD (assessed by a symptom-score questionnaire) and was divided into group 1 (those with preoperative GERD symptoms only) and group 2 (those with preoperative and postoperative GERD symptoms). INTERVENTIONS: Laparoscopic AGB was performed according to the pars-flaccida technique. MAIN OUTCOME MEASURES: All patients underwent preoperative and annual postoperative symptom scoring, endoscopy, esophageal barium swallow tests, esophageal manometry, and 24-hour pH monitoring. RESULTS: Mean follow-up time was 33 months (range, 12-49 months). A total of 164 patients (27.9%) were diagnosed as having preoperative GERD symptoms. In 112 (68.3%) of these patients GERD symptoms vanished postoperatively (group 1), whereas 52 patients (31.7%) remained symptomatic after undergoing laparoscopic AGB implantation (group 2). Preoperatively, group 2 patients showed significantly poorer esophageal body motility compared with group 1 patients (20.8% vs 12.8% defective propagations; P = .007). In group 2 the mean symptom scores for dysphagia (0.4 vs 0.9) and regurgitation (0.6 vs 1.4) deteriorated significantly following laparoscopic AGB implantation, respectively. Eighteen patients (34.6%) in group 2 developed esophageal dilatation. CONCLUSIONS: Adjustable gastric banding provides a sufficient antireflux barrier in most of the obese patients with GERD. However, in patients with preoperatively defective esophageal body motility, AGB may aggravate GERD symptoms and esophageal dilatation. Alternative bariatric surgical procedures should be considered in these patients.

We present a case report of hepatic resection performed laparoscopically for a giant symptomatic hemangioma. The patient was a 50-year-old woman who was diagnosed with a giant hemangioma 20 cm in diameter. As in the case of our patient, laparoscopic resection of hepatic hemangiomas can be performed successfully, even when dealing with giant hemangiomas. However, a thorough preoperative assessment and a structured approach, in our case including preoperative embolization, is crucial for success.

Following my prior study of long-term results after laparoscopic gastric banding concerning operative outcome and complications involving the gastric band itself, I now focus on long-term quality-of-life improvement in the same study group after body-contouring surgery. As determined from our electronic patient data system, 72 patients from the former study group subsequently sought body-contouring surgery at our hospital after successful weight loss. Patients were enrolled in a telephone interview and asked about their expectations and body image before and after postbariatric aesthetic surgery and how it altered their well-being in addition to the weight loss achieved with the gastric band. All patients undergoing postbariatric aesthetic surgery felt extremely uneasy with the hanging skin resulting from weight reduction. Patients cannot imagine the degree of dissatisfaction they will experience from the sagging skin that comes with weight loss. Hardly any patient expected fewer scars than he ultimately had after body-contouring surgery and reported an extreme improvement in body image. Gastric banding should not be performed without informing patients about the need for postbariatric body-contouring surgery, because most patients not forewarned suffer greatly from their body image after weight loss.

BACKGROUND: Laparoscopic adjustable gastric banding is effective in inducing weight loss, as well as being minimally invasive, totally reversible, and adjustable to the patient's needs. The aim of this study was to assess the efficacy and safety of adjustable gastric banding with the Swedish band (SAGB) in super-obese patients. PATIENTS AND METHODS: Between January 1996 and December 2003, 682 patients (570 women, 112 men) underwent SABG implantation. In these patients, there were 60 super-obese patients with a BMI >/= 50 kg/m(2). Two groups of patients were analyzed: Group 50 (n = 30 patients) with a BMI 50-54 kg/m(2) and Group 55 (n = 30 patients) with a BMI >/= 55 kg/m(2). 13 different surgeons (9 general and 4 bariatric surgeons) performed the SAGB. All data (demographic and morphologic data, operative data, and follow-up data) were prospectively collected in a computerized data bank. RESULTS: 60 patients (8.8%) out of 682 were super-obese and entered the study. Mean %EWL was 39.2 at 1 year and 60.4 at 4 years, BMI fell from 55.5 to 34.7 at 4 years. The complication rate was 26.7% (16/60). General surgeons 12/60 (20%) had more complications than bariatric surgeons 4/60 (6.7%). In Group 50, mean %EWL was 42.1 at 1 year, 55.9 at 2 years, 61.5 at 3 years and 59.9 at 4 years. BMI fell from 51.8 to 33.2 at 4 years. Postoperative complications occurred in 6/30 patients (20%): pouch dilatation (n=2), band migration (n=2) and band leakage (n=2). In Group 55, mean %EWL was 36.8 at 1 year, 55.3 at 2 years, 55.8 at 3 years, and 59.4 at 4 years. BMI fell from 59.1 to 36.4 at 4 years. Postoperative complications occurred in 10/30 patients (33.3%): pouch dilatation (n=2), band migration (n=3) and band leakage (n=5). There was no mortality. CONCLUSION: SAGB is an effective procedure for the surgical treatment of super-obesity. Because of the high complication rate, super-obese patients should only be treated by experienced bariatric surgeons.

BACKGROUND: The advantages of laparoscopy over open surgery are well known. The aim of this study was to compare our results with Swedish adjustable gastric banding (SAGB) with other laparoscopically performed bariatric procedures (gastric bypass, LapBand, vertical banded gastroplasty). METHODS: Between January 1996 and December 2001, 454 patients (381 women, 73 men) underwent laparoscopic SAGB. All data (demographic and morphologic, co-morbidities, operative, and follow-up) were prospectively collected in a computerized databank. RESULTS: Mean follow-up was 30 months (range 1-66). Average total weight loss was 35.5 kg after 1 year, reaching an average total of 54 kg after 3 years. Mean excess weight loss was 72% after 3 years, and the BMI decreased from 46.7 to 28.1 kg/m(2). Patients with co-morbidities reported marked improvement of their accompanying diseases. Complications requiring reoperation occurred in 7.9%. There was no mortality. The clinical outcome compared with the other laparoscopic bariatric procedures showed no significant difference. CONCLUSION: All laparoscopically performed bariatric procedures are very promising. The great advantage of laparoscopic adjustable gastric banding is that this operation is minimally invasive to the stomach, totally reversible and adjustable to the patients' needs.

BACKGROUND: The aim of this study was to assess the incidence of intragastric migration of the Swedish adjustable gastric band (SAGB) and to evaluate the safety and effectiveness of gastroscopic band removal. METHODS: Between January 1996 and December 2001, 454 patients (381 women, 73 men) underwent a laparoscopic SAGB operation. All data (age, gender, pre- and postoperative weight, time of weight gain, band filling status, endoscopic diagnosis of migration, total weight reduction) were prospectively collected in a computerized data bank. RESULTS: Out of the 454 SAGB operations, 14 (3.1%) intragastric band migrations were observed. The average preoperative weight was 122.2 kg and the average postoperative minimum weight was 80.4 kg. All 14 patients had unexplained weight gain on an average of 20 months after the operation. The average band filling status was 8.2 ml. In 12 patients, the band was removed endoscopically, avoiding laparotomy. The remaining 2 patients are under endoscopic surveillance. The mean operating time was 120 minutes. No peri- or postoperative complication was observed. CONCLUSION: Intragastric band migration is a rare complication and should be considered if a patient starts to regain weight. Migration does not require immediate therapy and therefore this complication could be safely treated endoscopically.

BACKGROUND: Laparoscopic adjustable gastric banding is effective in inducing weight loss, as well as being minimally invasive, totally reversible, and adjustable to the patient's needs. Nevertheless, leakage of the adjustable balloon is a known complication. The aim of this study was to assess the incidence and reasons for balloon leakage of the Swedish adjustable gastric band (SAGB). PATIENTS AND METHODS: Between January 1996 and December 2002, 566 patients (475 women, 91 men) underwent a laparoscopic SAGB implantation. Two groups of patients were analyzed: patients with early postoperative leakage (Group E) and patients with late postoperative leakage (Group L). All data (age, gender, pre- and postoperative weight, time of weight gain, band filling status) were prospectively collected in a computerized data bank. For the detection of gastric band leakage, radiography and the technetium-99m colloid scintigraphy was used. RESULTS: 25 band leakages were observed in 22 patients (4.4%). All these patients had a silent presentation of band leakage, with weight regain and an ability to eat without major restriction. Band leakages in group E were detected during the band filling period after a median follow-up of 8 months and after 30.3 months (P <0.0001) in group L. In group E, all 13 leakages possibly resulted from inappropriate handling of the device during surgery. In 2 cases in group L, a tear of the balloon had occurred where it is fixed to the band. The other 10 bands showed breaks at the edges of the inner side of the balloon. All leakages could be detected by (99m)Tc colloid scintigraphy, whereas only 58% of the leakages could be detected by radiography. CONCLUSION: Band leakage is a rare complication and should be considered if a patient starts to regain weight. Operative failure as well as material defects may account for this complication. The balloon leakage can effectively be detected by (99m)Tc colloid-scintigraphy.

BACKGROUND: Adjustable gastric banding and esophagogastric banding may affect the function of the lower esophageal sphincter (LES) and esophageal motility in the long-term. Both methods were evaluated in a prospective randomized trial. MATERIALS AND METHODS: Group 1 comprised 28 patients who underwent laparoscopic adjustable gastric banding and Group 2 consisted of 24 patients in whom adjustable esophagogastric banding was performed. Swedish Adjustable Gastric Bands were used in all patients. Body mass index (BMI), perioperative complications and reflux symptoms were assessed and upper gastrointestinal endoscopy, esophageal barium studies, esophageal manometry and 24-hour esophageal pH-monitoring were performed pre- and postoperatively. 18 (Group 1) and 14 (Group 2) patients completed the postoperative follow-up procedure after a median of 23 and 24 months, respectively. RESULTS: Postoperatively the median BMI dropped equally in both groups. Perioperative complications requiring re-intervention were significantly more frequent in Group 2 than in Group 1. Heartburn improved equally in both groups following surgery; however, regurgitation and esophagitis were significantly more common in Group 2 than in Group 1.24-hour esophageal pH-monitoring and the LES resting pressure improved equally in both groups, but there was a significant impairment of the LES relaxation and the esophageal peristalsis, which was more pronounced in Group 2 than in Group 1. This caused significant esophageal stasis as shown by barium studies. CONCLUSIONS: Both techniques, gastric and esophagogastric banding, provide effective weight loss in morbidly obese patients but affect the esophagogastric junction. Although both procedures strengthen the antireflux-barrier, LES relaxation becomes impaired, thus promoting esophageal dilatation and esophageal stasis. This is more pronounced following esophagogastric banding than following the classic procedure. Since the esophagogastric banding results in more complications requiring re-intervention, we believe that this procedure should not be used any more.

BACKGROUND: Laparoscopic silicone adjustable gastric banding (SAGB) has gained popularity for the surgical treatment of morbid obesity. The implantable gastric stimulator (IGS) system represents a novel surgical alternative. We aimed to assess the feasibility of robotic-assisted laparoscopic bariatric operations and to critically elucidate the technical and financial advantages and patient outcome. METHODS: Robotic-assisted laparoscopic bariatric procedures were performed on 10 consecutive patients using the daVinci robot system (4 SAGB, 4 IGS, 2 SAGB revisions). 10 conventional laparoscopic-operated patients (4 SAGB, 4 IGS, 2 SAGB revisions) during the learning curve served as controls. Equipment, operative technique and procedural time were evaluated. A cost analysis was calculated. RESULTS: The personnel equipment, numbers of trocars and operation technique were comparable in both groups. The mean operative time was 137 min (range 110-175) and 97 min (60-140) in robotic-assisted and conventional laparoscopy, respectively (P =0.04). Establishment of the pneumoperitoneum and placement of trocars and robotic arms took a mean of 30 min (15-45) in the robotic-assisted group, compared with 5 min in the control group (P <0.001). In 1 patient, intraoperative gastric injury was suspected and led to band removal in the robotic-assisted group. There was no postoperative complication. Average procedural costs were significantly higher in the robotic-assisted group. CONCLUSION: Primary and revisional robotic-assisted bariatric surgery is technically simple, with the benefit of precise instrument handling. However, it is still expensive, the set-up of the system is time-consuming, and a limited variety of instruments are available presently.

BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) is an effective method in the treatment of morbid obesity. However, it is unknown, whether deflating the gastric band before operations under general anesthesia is necessary to avoid complications such as nausea, vomiting, respiratory complications, and weight regain. METHODS: Between January 1996 and June 2001, we performed LAGB on 408 patients at the University Hospital of Innsbruck. Of these patients, we identified 68 (16.7%) patients who were to undergo subsequent unrelated general, reconstructive, vascular, or orthopedic procedures. These patients were prospectively randomized into two groups: group 1 (n = 32) preoperative deflation of the adjustable band system and group 2 (n = 36) without preoperative deflation of the adjustable band system. RESULTS: There were no anesthetic or perioperative band-related complications in either group 1 or group 2. There were two reoperations necessary due to surgical complications unrelated to the gastric band. CONCLUSIONS: Operations after adjustable gastric banding can be safely performed without deflating the adjustable system.

Although surgery should be considered the last resort to treat morbid obesity, it is also the only treatment that works for this condition. In the era of minimally invasive surgery, laparoscopic adjustable banding and laparoscopic gastric bypass appear to offer the next logical step in the field of bariatric surgery. Laparoscopic gastric banding in particular has wide appeal since it demands less time and relative skill compared to the laparoscopic gastric bypass; however, knowledge of subtle details and expertise is required to reproduce favorable outcomes of permanent weight reduction and minimal complications. Still, there was a high failure rate of the LASGB in a multi-centre U.S. trail reported despite very promising results from Europe and Australia. Which procedure is more favorable, LASGB or laparoscopic GBP, is still under discussion and requires further prospective and comparative studies [26].

BACKGROUND: Patients who are suspected of having acute appendicitis usually undergo surgery in order to avoid life-threatening complications such as perforation and peritonitis. However, acute appendicitis is difficult to distinguish from other sources of right-sided abdominal pain. The clinical picture is almost indistinguishable from appendiceal diverticulitis, which is a rare entity and remains a difficult diagnostic problem. PATIENTS AND METHODS: We describe the case of a 39-year-old male with perforated appendiceal diverticulitis. The patient was admitted to our surgical unit with acute appendicitis-like symptoms and underwent surgery with a diagnosis of suspected acute appendicitis. RESULTS: The patient was found to have perforated appendiceal diverticulitis and standard appendectomy with abdominal lavage was carried out. DISCUSSION: Most patients presenting with acute right-sided peritonitic pain are diagnosed and managed as cases of acute appendicitis. Acute pain in the lower right side of the abdomen caused by appendiceal diverticulitis is very rare and clinically indistinguishable from acute appendicitis. Inflammatory complications of appendiceal diverticula mimic acute appendicitis. CONCLUSION: Every surgeon should be aware of the possibility of diverticulitis of the appendix in the operating room, even if this does not change the operative management. As diverticula of the cecum can be found as solitary lesions, as multiple lesions confined to the right colon, or as part of a generalized disease of the entire colon, postoperative barium enema examination may be useful.

OBJECTIVE: With the use of abdominal vacuum therapy, we have developed a damage control concept for patients with perforated diverticulitis and generalized peritonitis. The primary aim of this concept was to enhance recovery and allow bowel reconstruction in a second-look operation. METHODS: A total of 51 patients (28 female, 55%) with a median (range) age of 69 (28-87) years, with perforated diverticulitis Hinchey III (n = 40, 78%) or Hinchey IV (n = 11, 22%) and a median (range) Mannheim peritonitis index of 26 (12-39), admitted between October 2006 and September 2011, were prospectively enrolled in the study. At initial operation, limited resection of the diseased segment, lavage, and application of abdominal vacuum-assisted closure dressing was performed. After patient resuscitation, a second look was performed in an elective setting. RESULTS: Hospital mortality rate was 9.8%; 35 (76%) of patients were discharged with reconstructed colon, and 93% of patients live without a stoma at follow-up. Risk factors for mortality were American Society of Anesthesiologist score (p = 0.01), organ failure at initial presentation (p = 0.03), cardiac comorbidity (p = 0.05), and a Hartmann procedure at second look (p = 0.00). CONCLUSION: With this abdominal vacuum-based damage control concept, an acceptable hospital mortality rate and a high rate of bowel reconstruction at second look were achieved in patients with perforated diverticulitis and generalized peritonitis.

BACKGROUND: This phase II trial assessed the feasibility and safety of induction chemotherapy with cisplatin (25 mg/m(2) d1-5, d29-34)/docetaxel (75 mg/m(2) d1, d29)/5-fluorouracil (5-FU, 750 mg/m(2) d1-5, d 29-34) followed by external beam radiotherapy concurrent with docetaxel (15 mg/m(2) d1,8,15,22) and 5-FU (300 mg/m(2) continuous infusion on the days of radiotherapy). PATIENTS AND METHODS: Twenty-four patients with locally advanced carcinoma of the esophagus were included. Following chemotherapy and chemoradiation eligible patients underwent esophagectomy. If surgery could not be performed patients received definitive radiation. RESULTS: Sixteen patients underwent resection. Pathologic complete remission was achieved in 5 of those 16 patients, 13 patients had downstaging of disease. R0 resection was feasible in all 16 patients. Main grade 3 and 4 toxicities were neutropenia in 10 patients, diarrhea in 4 and postoperative morbidity in 9 patients. At a median follow-up of 16.5 months 15 patients are alive; median survival has not yet been reached. CONCLUSION: Neoadjuvant treatment with cisplatin/docetaxel/5-fluorouracil followed by chemoradiation with docetaxel/5-fluorouracil is safe, feasible, and effective.

This study was performed to assess our long-term results with laparoscopic gastric banding in patients with an observation period of at least 9 years calculated from the date of operation. Between January 1996 and December 2000, a total of 276 patients (83% female) underwent laparoscopic gastric banding at our institution. Mean preoperative body mass index (BMI) was 44 +/- 6 kg/m(2). BMI after 1, 5, 7, 9, and 10 years was 33 +/- 6, 30 +/- 6, 31 +/- 6, 32 +/- 7, and 31 +/- 7 kg/m(2), respectively. Mean excess weight loss after 1 year was 57.1 +/- 23.0% and after 5, 7, 9, and 10 years 73.2 +/- 29.6%, 65.9 +/- 29.3%, 61.8 +/- 32.8%, and 64.0 +/- 32.1%, respectively. Median completeness of follow-up was 80%. Of the study population, 146 (52.9%) patients had at least one complication requiring reoperation. Presently, only 148 (53.6%) patients still have their original band, 49 (17.8%) had their original band replaced with a new one, and 79 (28.6%) had their band removed. Thirty-three patients had no second bariatric operation, a Roux-en-Y gastric bypass was done in 39 patients, and six patients underwent sleeve gastrectomy. Our long-term results are good with regard to weight loss in those patients who still have their band in situ. This is accompanied by a high complication rate and a 29% band loss rate.
