ABSTRACT

Upper gastrointestinal bleeding from esophagogastric varices is a common scenario, especially in patients with portal hypertension induced by liver cirrhosis or other diseases with thrombosis of the splenic vein. However, accessory spleen as pathophysiological cause of a regional, left-sided portal hypertension and consecutive development of isolated gastric varices is rare. We report a case of recurrent gastric variceal bleeding resulting from sinistral portal hypertension associated with an accessory spleen in a patient who had traumatic splenectomy many decades before. The accessory spleen is an extremely rare cause for the development of regional, left-sided portal hypertension leading to isolated gastric varices. Minimally invasive splenectomy is a safe and efficient treatment option.

ABSTRACT

Background: This open-label, phase III trial compared chemoradiation followed by surgery with or without neoadjuvant and adjuvant cetuximab in patients with resectable esophageal carcinoma. Patients and methods: Patients were randomly assigned (1 : 1) to two cycles of chemotherapy (docetaxel 75 mg/m2, cisplatin 75 mg/m2) followed by chemoradiation (45 Gy, docetaxel 20 mg/m2 and cisplatin 25 mg/m2, weekly for 5 weeks) and surgery, with or without neoadjuvant cetuximab 250 mg/m2 weekly and adjuvant cetuximab 500 mg/m2 fortnightly for 3 months. The primary end point was progression-free survival (PFS). Results: In total, 300 patients (median age, 61 years; 88% male; 63% adenocarcinoma; 85% cT3/4a, 90% cN+) were assigned to cetuximab (n = 149) or control (n = 151). The R0-resection rate was 95% for cetuximab versus 97% for control. Postoperative treatment-related mortality was 6% in both arms. Median PFS was 2.9 years [95% confidence interval (CI), 2.0 to not reached] with cetuximab and 2.0 years (95% CI, 1.5-2.8) with control [hazard ratio (HR), 0.79; 95% CI, 0.58-1.07; P = 0.13]. Median overall survival (OS) time was 5.1 years (95% CI, 3.7 to not reached) versus 3.0 years (95% CI, 2.2-4.2) for cetuximab and control, respectively (HR, 0.73; 95% CI, 0.52-1.01; P = 0.055). Time to loco-regional failure after R0-resection was significantly longer for cetuximab (HR 0.53; 95% CI, 0.31-0.90; P = 0.017); time to distant failure did not differ between arms (HR, 1.01; 95% CI, 0.64-1.59, P = 0.97). Cetuximab did not increase adverse events in neoadjuvant or postoperative settings. Conclusion: Adding cetuximab to multimodal therapy significantly improved loco-regional control, and led to clinically relevant, but not-significant improvements in PFS and OS in resectable esophageal carcinoma. Clinical trial information: NCT01107639.

ABSTRACT

OBJECTIVES: The Model for End-Stage Liver Disease score and King's College Hospital (KCH) criteria are accepted prognostic models acute liver failure (ALF), while the use of (APACHE) scores predict to outcomes of emergency liver transplantation is rare. MATERIALS AND METHODS: The present study included 87 patients with ALF who underwent liver transplantation. We calculated (KCH) criteria, as well as MELD, APACHE II, and APACHE III scores at the listing date for comparison with 3-month outcomes. RESULTS: According to the Youden-Index, the best cut-off value for the APACHE II score was 8.5 with 100% sensitivity, 49% specificity, 24% positive predictive value (PPV), and 100% negative predictive value (NPV). Patients with <8.5 points had a significantly higher survival rate (P < .05). The proposed APACHE III cut-off was 80. The APACHE III score demonstrated the highest specificity and PPV (90% specificity, 50% PPV). The NPV was 92%. With a 90-point threshold the specificity increased to 98% with 75% PPV and 89% NPV. Only 1 of 4 patients with a score >90 survived transplantation (P = .001). MELD score and KCH criteria were not significant (P > .05). According to the Hosmer-Lemeshow test, only the APACHE III score adequately describe the data. CONCLUSIONS: The APACHE III score was superior to KCH criteria, MELD score, and APACHE II score to predict outcomes after transplantation for ALF. It is a valuable parameter for pretransplantation patient selection.

ABSTRACT

BACKGROUND: To evaluate surgical outcome and survival benefit after quaternary cytoreduction (QC) in epithelial ovarian cancer (EOC) relapse. METHODS: We systematically evaluated all consecutive patients undergoing QC in our institution over a 12-year period (October 2000-January 2012). All relevant surgical and clinical outcome parameters were systematically assessed. RESULTS: Forty-nine EOC patients (median age: 57; range: 28-76) underwent QC; in a median of 16 months (range:2-142) after previous chemotherapy. The majority of the patients had an initial FIGO stage III (67.3%), peritoneal carcinomatosis (77.6%) and no ascites (67.3%). At QC, patients presented following tumour pattern: lower abdomen 85.7%; middle abdomen 79.6% and upper abdomen 42.9%. Median duration of surgery was 292 min (range: a total macroscopic tumour clearance could be achieved. Rates of major operative morbidity and 30-day mortality were 28.6% and 2%, respectively.Mean follow-up from QC was 18.41 months (95% confidence interval (CI):12.64-24.18) and mean overall survival (OS) 23.05 months (95% CI: 15.5-30.6). Mean OS for patients without vs any tumour residuals was 43 months (95% CI: 26.4-59.5) vs 13.4 months (95% CI: 7.42-19.4); P=0.001. Mean OS for patients who received postoperative chemotherapy (n=18; 36.7%) vs those who did not was 40.5 months (95% CI: 27.4-53.6) vs 12.03 months (95% CI: 5.9-18.18); P<0.001.Multivariate analysis indentified multifocal tumour dissemination to be of predictive significance for incomplete tumour resection, higher operative morbidity and lower survival, while systemic chemotherapy subsequent to QC had a protective significant impact on OS. No prognostic impact had ascites, platinum resistance, high grading and advanced age. CONCLUSION: Even in this highly advanced setting of the third EOC relapse, maximal therapeutic effort combining optimal surgery and chemotherapy appear to significantly prolong survival in a selected patients 'group'.

ABSTRACT

Although laparoscopic fenestration has become an established treatment in symptomatic liver cyst patients in the recent years, the success of surgical treatment cannot only be evaluated by post-operative morbidity and mortality. Therefore, the aim of this study was to analyze the safety of laparoscopic fenestration of non-parasitic liver cysts and to assess the impact of this therapy on patients' quality of life. A total of 43 patients who underwent laparoscopic fenestration of non-parasitic liver cysts at our center were included in this study. Post-operative course was assessed and patients' quality of life was evaluated before surgery and at present time using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (QLQ C-30). The results were that, post-operative morbidity and mortality rates were 0%. After a median follow-up of 49 months (19-97 months) the recurrence rate was 11.1% for simple liver cysts (SLC) and 42.9% for polycystic liver disease (PCLD). Thirty-one out of 43 patients (72.1%) completed the EORTC C-30 questionnaire. There was highly significant post-operative improvement in global health status (p < 0.001) as well as in physical (p = 0.002), role (p = 0.004), emotional (p = 0.003) and social (p = 0.001) functioning. Furthermore, a significant reduction of symptoms could be shown for pain (p < 0.001), nausea and vomiting (p = 0.001), appetite loss (p = 0.006), insomnia (p = 0.04) and fatigue (p = 0.025). To conclude, laparoscopic fenestration of symptomatic non-parasitic liver cysts is a safe procedure with good long-term results and the patients' benefit of this intervention is excellent as shown by highly significant improvement in patients' quality of life.

ABSTRACT

BACKGROUND: Postoperative tumor-residual-mass is the most important prognostic factor in epithelial ovarian cancer (EOC). Aim of our study was to define risk factors for incomplete tumor resection in advanced primary EOC. PATIENTS & METHODS: A validated intraoperative documentation tool ("Intraoperative-Mapping of Ovarian-Cancer" = "IMO") was applied to systematically evaluate intraabdominal tumor dissemination pattern, maximal tumor load, tumor residuals and operative morbidity for all EOC-patients who underwent primary surgery in our institution during 09/2000-08/2009. Univariate- and multivariate analysis were performed to identify independent risk factors of incomplete tumor resection and operative complications. RESULTS: We evaluated 360 consecutive EOC-patients of FIGO-stage-III/IV. In 221(61%) patients a complete tumor resection could be obtained. In 50(14%) patients tumor residuals were <0.5 cm. Sixty (17%) patients developed a major (14%) complication. Multivariate analysis identified intestinal resection (OR:2.0; 95%CI:1.14-3.4; p = 0.01) and macroscopical tumor residuals (OR:0.5; 95%CI:0.2-1.2; p = 0.05) as independent predictors of major operative morbidity. Tumor dissemination pattern and maximal tumor load were significantly different between tumor-free and not-tumor-free operated patients, with less extrapelvic tumor involvement in the tumor-free group (p < 0.001). More than 4 IMO-fields of tumor involvement (OR:3.3; 95%CI:1.5-7.0; p = 0.002) were identified to be of predictive significance for incomplete tumor resection. FIGO-stage, histology, age, CA125-levels, bowel resection and ascites did not affect optimal tumor resectability. CONCLUSIONS: Tumor expanding in multiple (>4) abdominal quadrants was the major negative predictors for complete tumor resection in primary EOC-patients. Bowel resection and macroscopical tumor residuals were of predictive value for a higher operative major morbidity. Identifying high-risk patients for suboptimal tumor resection and operative complications may improve surgical outcome in advanced primary EOC.

ABSTRACT

Technological developments, advances in perioperative medicine and ongoing scientific research have led to reduced rates of mortality and morbidity in patients undergoing major liver surgery. Under these conditions, the frontier of resectability is constantly in movement towards more complex cases with extended tumor spread and potentially minimized remnant liver volume. A promising technique to support oncological correct and safe liver surgery is the introduction of preoperative computer based planning models and intraoperative navigation systems. Whereas three-dimensional (3D) liver models are commercially available and have been clinically implemented, the use of navigation systems is currently under evaluation by different groups using a variety of techniques. This manuscript is meant to give the reader an overview on current developments, difficulties and future aspects of image guided liver surgery.

ABSTRACT

INTRODUCTION: Liver tumors should be surgically treated whenever possible. In the case of bilobar disease or coexisting liver cirrhosis, surgical options are limited. Radiofrequency ablation (RFA) has been successfully used for irresectable liver tumors. The combination of hepatic resection and RFA extends the feasibility of open surgical procedures in patients with liver metastases and hepatocellular carcinoma (HCC). PATIENTS AND METHODS: RFA was performed with two different monopolar devices using ultrasound guidance. Intraoperative use of RFA for the treatment of liver metastases or HCC was limited to otherwise irresectable tumors during open surgical procedures including hepatic resections. Irresectability was considered if bilobar disease was treated, the functional hepatic reserve was impaired or appraised marginal for allowing further resection. RESULTS: Ten patients with both liver metastases and HCC, and two patients with cholangiocellular carcinoma were treated. Complete initial tumor clearance was achieved in all patients. Two patients of the metastases group and five patients of the HCC group suffered from local recurrence after a median of 12 months (1-26) (local recurrence rate 32%). Five patients of the metastases group and six patients of the HCC group developed recurrent tumors in different areas of the ablation site after a median time of 4 months (2-18) (distant intrahepatic recurrence in 55%). Survival at 31 months was 36%. CONCLUSION: RFA extends the scope of surgery in some candidates with intraoperatively found irresectability.

ABSTRACT

BACKGROUND: In recent years, laparoscopic hepatic resection is performed by an increasing number of surgeons. Despite many advantages of the laparoscopic procedure, it is unclear whether the pneumoperitoneum affects the postoperative liver regeneration after liver resection. The current study aimed to investigate the influence of a carbon dioxide (CO(2)) pneumoperitoneum on liver regeneration in a rat model. METHODS: In this study, 60 male Wistar rats were subjected to 70% partial hepatic resection. Of these 60 animals, 30 underwent preoperative pneumoperitoneum at 9 mmHg for 60 min. After hepatic resection, the rats were killed at 12, 24, and 48 h, and on days 4 and 7. The outcome parameters were hepatocellular injury (plasma aminotransferases), oxidative stress (plasma malondialdehyde), interleukin-6 (IL-6), and liver regeneration (mitotic index, KI-67; regenerating liver mass). RESULTS: The mitotic index was significantly lower in the pneumoperitoneum group than in the group without pneumoperitoneum at all time points (p < 0.05). In the pneumoperitoneum group, KI-67 was significantly lower on day 4 (p < 0.05). The liver regeneration rate was significantly lower for the animals with pneumoperitoneum on days 2 and 4 (p < 0.05). The postoperative hepatocellular injury was significantly greater after pneumoperitoneum at 12, 24, and 48 h (p < 0.05). Plasma malondialdehyde and IL-6 were significantly higher in the pneumoperitoneum group at 24 h and on day 4 (p < 0.05). CONCLUSION: This study showed that pneumoperitoneum before extended liver resection impaired postoperative liver regeneration. Oxidative stress reaction and hepatocellular damage was markedly higher after pneumoperitoneum. Further investigations, especially with patients that have impaired liver function, are necessary for clinical consequences to be drawn from these results.

ABSTRACT

INTRODUCTION: Adenocarcinoma of the esophagogastric junction (AEG) is a particular tumour entity because two substantially different surgical procedures are required according to the location. There is no difference in long-term prognosis between the tumour types in spite of the different surgical procedures. We were interested to evaluate the clinical and pathological prognostic factors of the AEGs which were operated in our department. PATIENTS AND METHODS: 108 patients were operated for AEG between 1.1.2000 and 1.4.2006 in our institution. 32 (29.6 %) patients with distal esophageal cancer (type I according to Siewert) underwent a transthoracic esophagectomy with gastric pull-up and two-field lymphadenectomy. 57 (52.8 %) patients with type II and 19 (17.6 %) patients with type III cancers received an extended gastrectomy with D2 lymphadenectomy. The retrospective analysis was focused on clinical and pathological parameters. Possible differences between the tumour types were also evaluated. Median follow-up was 11.4 months (range: 1-57 months). RESULTS: Follow-up data were complete for 107 patients. A median survival of 17.4 +/- 3.25 months and a cumulative survival of 30 % were independent of the tumour location and the surgical procedure. Overall hospital mortality was 3.7 %. The univariate analysis showed that survival was significantly associated with the T category, lymph node status, lymphangio- and angioinvasion and tumour grading. In the multivariate analysis, only lymph node status was identified as an independent prognosis factor for survival. Where-as the R status was not a prognostic factor per se, how-ever, patients with an R0 situation without lymphangio- and angioinvasion had a significantly better survival compared to all other patients (p = 0.001). An increased angioinvasion rate was observed in type III tumours (52.6 %) in comparison to type I (21.9 %) and type II (21.1 %) tumours. CONCLUSION: The prognostic factors of our patients determined substantially the prognosis of the patients. Patients with lymph- or haemangioinvasion should regarded as high-risk patients independent of the R status. Close oncological follow-up including potential adjuvant treatment in these patients is recommended.

ABSTRACT

The aim of this study was to identify suitable interactive (dynamic) magnetic resonance (MR) sequences for real-time MR-guided liver dissection in a 1.0-T high field open MRI system. Four dynamic sequences encompassing balanced steady state free precession (bSSFP), T1W gradient echo (GRE), T2W GRE and T2W fast spin echo (FSE) were analysed regarding the image quality, artefact susceptibility and the performance of SNR and CNR. The T2W FSE sequence (1.5 s/image) was considered superior because of an intraoperative SNR of 6.9 (+/-0.7) and CNR (vessel to parenchyma) of 5.6 (+/-1.7) in the interventional setting. As a proof of concept, MR-guided laparoscopic liver resection was performed in two healthy domestic pigs by using the T2W FSE sequence. The additional MR images offered simultaneous multiplanar real-time visualisation of the liver vessels during the intervention and thereby increased the anatomical orientation of the surgeon.

ABSTRACT

Precise classification of cancers of the esophagogastric junction according to Siewert may be difficult for the presence of Barrett's esophagus or hiatal hernia, which subsequently leads to a difficult choice of the surgical procedure of esophagectomy or gastrectomy. Ninety-six patients with such cancers were operated on in our department in 7 years. Twenty-nine patients (30.2%), classified as type I (group 1), underwent a transthoracic esophagectomy with gastric pull up. Sixty-seven patients (69.8%) classified as type II or III (group 2) underwent an extended gastrectomy. We compared the patients of both groups retrospectively for disease-free survival and postoperative complications. The general performance status of most patients was comparable in both groups and was assigned to the American Society of Anesthesiologists class II or III. Statistically significant differences between the groups were seen for the postoperative reintubation rate [group 1: 31.0% vs. group 2: 9.0% (P = 0.009)], median time for surgery [group 1: 6 (3.5-8.5) hours vs. group 2: 4.7 (2.2-11.5) hours (P = 0.001)], time in the intensive care unit [group 1: 6 (3-85) days vs. group 2: 3 (1-54) days (P = 0.001)], median hospitalization time [group 1: 23 (14-105) days vs. group 2: 18 (10-63) days (P = 0.018)]. No statistical difference was observed for the recurrence-free survival of 40% after 3 years (P = 0.311), the mortality rate, the morbidity rate (P = 0.108), surgical and respiratory complications, and the incidence of anastomotic leakage (P = 0.645). We conclude that in selected cases it may be possible to perform an extended gastrectomy for small type I cancers.

ABSTRACT

BACKGROUND: An elevated body mass index (BMI) is associated with an increased incidence of cancer at the gastro-oesophageal junction. Less is known about the postoperative complication rate and prognosis in relation to the BMI. PATIENTS AND METHODS: We investigated 108 patients with cancer of the cardia and a BMI below (group 1, n = 56) or above (group 2, n = 52) 25 kg / m (2), who were operated from 2000 to 2006 in our department. According to the Siewert classification, the tumours were subdivided into 3 types. Patients with type I cancers (n = 26) received a transthoracic oesophageal resection with gastric pull up. Patients with type II (n = 61) or type III (n = 21) cancers underwent an extended gastrectomy. The complication rates and survival were analysed. RESULTS: The complications were pulmonary (respiratory insufficiency n = 12, pneumonia n = 12, bronchitis n = 7, pulmonary embolism n = 2), surgical (anastomotic leakage n = 7, abscesses n = 8, bleeding n = 2, chylus fistula n = 1), or functional (dysphagia n = 5, nausea n = 5, heart burn n = 4, delayed enteral passage n = 6, vomiting n = 9). Patients of group 2 showed more delayed enteral passages (5 vs. 1) and more vomiting (7 vs. 2) than those of group 1. The median stay in the intensive care unit was shorter in group 1 than in group 2 (3 vs. 5 days) (p = 0.021). Overall hospitalisation was 14 days in the mean in both groups. We found no significant difference in the postoperative mortality of 6.5 % (n = 7) between the two groups. Overall survival after a follow-up of 42 months was 34 % (group 1) and 25 % (group 2). The difference did not reach statistical significance (p = 0.961). Patients with an elevated BMI show slightly more complications than those with a lower BMI. CONCLUSIONS: Our data show that patients with elevated BMI have slightly more complications and an identical long term survival as patients with normal body weight.

ABSTRACT

BACKGROUND: Acute appendicitis is the most common cause of an acute abdomen in pregnancy. However, due to the potential fetal risk associated with the CO2-pneumoperitoneum and various operative technical reasons there is still controversy about the role of laparoscopic appendectomy in pregnant women. PATIENTS AND METHODS: Between January 2000 and November 2005, 283 women between 17 and 45 years with suspected appendicitis underwent laparoscopic appendectomy at our institution. Fifteen of these patients (5.3 %) were pregnant at the time of surgery (mean age, 28 years; range, 18-40 years; mean gestational age, 21.9 weeks; range, 14-34 weeks). Perioperative obstetric monitoring included fetal ultrasound, including Doppler sonography and cardiotocography. Clinical data were collected prospectively. Complete follow-up data were available in 14 patients. RESULTS: All 15 patients underwent successful laparoscopic appendectomy. Mean operation time was 53 minutes (range, 30-100 minutes). The histologic appendicitis / appendectomy ratio was 73 %. One patient showed a postoperative pyelonephritis, another a cystitis. Average length of hospital stay was 5.5 days (range, 3-10 days). All fourteen pregnancies with complete follow-up resulted in delivery of healthy infants. The mean gestational age at delivery was 39.6 weeks (range, 35-42 weeks). Two patients (14.3 %) had a preterm delivery at 35 weeks with uncomplicated outcome. One patient underwent caesarean section at 41 weeks after chorioamnionitis. CONCLUSIONS: Laparoscopic appendectomy is a safe and effective method to treat acute appendicitis in pregnant women regardless of the trimester. For the best outcome the operation should be performed in a center where surgeons, perinatologist, obstetricians and anesthesiologists work together as a part of an interdisciplinary team.

Postoperative chylothorax after injury of the thoracic duct during esophagectomy is a rare but severe complication which may lead to serious problems such as loss of fat and proteins, and immunodeficiency. Without treatment mortality can rise to over 50%. From 1988 to 2005, we treated 10 patients with postoperative chylothorax after 409 resections of the esophagus (2.4%). Of these 10 patients nine underwent transthoracic esophagectomy with gastric pull-up to enable an intrathoracic (n = 7) or cervical (n = 2) anastomosis and one patient received a transhiatal esophagectomy with gastric pull-up and cervical anastomosis. The average amount of postoperative chylus was 2205 mL (200-4500 mL) per day. After a median postoperative interval of 10 days, relaparotomy and transhiatal double ligation of the thoracic duct was performed in nine out of 10 patients. One patient could be managed conservatively. The average amount of chylus was reduced to 151 mL per day (90.5%). Seven patients had no complications, and three suffered from postoperative pneumonia. Two of the patients with pneumonia recovered, and one died. Discharge from hospital, after ligation of the thoracic duct, was possible after a median time of 18 days (11-52). Ligation of the thoracic duct via relaparotomy appeared to be a simple and safe method to treat postoperative chylothorax.

ABSTRACT

BACKGROUND AND STUDY AIMS: The use of fibrin glue derived from humans or animals has been reported as an alternative method of mesh fixation, instead of staples, in inguinal hernia repair. However, fibrin sealants involve the potential risks of virus transmission or immunological reactions to foreign proteins. This risk could be avoided by using autologous fibrin derived from the patient. A feasibility study on the use of autologous fibrin was therefore carried out in patients undergoing laparoscopic transabdominal inguinal hernia repair. PATIENTS AND METHODS: In a series of 10 patients undergoing laparoscopic transabdominal inguinal hernia repair, autologous fibrin was produced from 120 ml of the patient's blood during the hernia repair. The process took an average of 20 min. The perioperative and postoperative results were compared with those in a control group of 20 patients in whom conventional fibrin was used. RESULTS: Producing and applying the autologous fibrin was uncomplicated. No differences in the outcome were observed between the two groups. One patient in the conventional fibrin group developed a seroma. None of the patients reported persistent pain. No recurrences were observed after a mean follow-up period of 9 months (range 6 - 12 months) in the conventional fibrin group and 7 months (range 6 - 8 months) in the autologous fibrin group. CONCLUSIONS: This feasibility study suggests that autologous fibrin sealant allowed adequate mesh fixation that did not differ from that in a control group in whom conventional fibrin glue was used. Autologous fibrin may be an interesting alternative for a variety of laparoscopic and endoscopic applications.

ABSTRACT

Traumatic aneurysms of the superior mesenteric artery, although uncommon, are nevertheless life-threatening because of their high risk of rupture. In this case report the aneurysm was accompanied by a burst fracture of the second lumbar spine nearly at the same height. In a prolonged case the diagnosis of the injury was delayed. The clinical manifestation of repeated episodes of abdominal pain did not recur after resection of the aneurysm and interposition of a venous autograft.

ABSTRACT

Injuries of the biliary tract following laparoscopic cholecystectomy have increased with the widespread use of the procedure. Compared to the conventional open choelycstectomy, the incidence of bile duct injuries is at least twofold higher after the laparoscopic procedure. A number of risk factors for the occurrence of bile duct injuries have been well described, including severe inflammation, bleeding, anatomical variations and lack of surgical experience. The appropriate management of bile duct injuries depends on the time of diagnosis after the injury and the type of injury. While peripheral leakages and short strictures can be treated endoscopically, extended injuries and long strictures require surgical reconstruction. The best long-term results are achieved with a tension-free, end-to-side mucosa-to-mucosa Roux-Y hepaticojejunostomy.

ABSTRACT

INTRODUCTION: Laparoscopic inguinal hernia repair offers more rapid recovery and less pain than with the traditional open approach. However, injury to the nerves of the lumbar plexus with subsequent chronic pain or neuralgia has a reported incidence of 2% during laparoscopic hernia repair, particularly when the transabdominal preperitoneal technique (TAPP) is used. These complications are inherent to the use of staples for fixation of the mesh. To avoid nerve irritation, we considered the use of fibrin sealant for the fixation of the mesh instead of staples. The aim of this study was to evaluate this technique and to compare the short-term follow-up of these patients with patients who underwent the staple repair technique. This is the first reported use of fibrin sealant in laparoscopic TAPP hernia repair. METHOD: Between September and November 2004, we performed 17 consecutive laparoscopic hernia repairs (TAPP) in 14 patients (3 bilateral hernias) with primary hernias. The prosthetic mesh was fixed (10 x 15 cm) with 1 ml fibrin. The fibrin was applied using a special laparoscopic applicator. The peritoneum was closed with absorbable sutures. The postoperative course of these patients was compared with a cohort of matched patients who received the traditional staple fixation of the prosthetic mesh. RESULTS: Patients were evaluated at a median follow-up of 10.4 months (3.8-16.0 months). All patients underwent postoperative physical examinations. No recurrent hernia was found. There were 2 seromas and one hematoma in the stapled group. In the stapled group, one patient had pain in the area of the lateral femoral cutaneous nerve. There was no postoperative complication in the non-stapled group. CONCLUSION: Fibrin fixation of the mesh during laparoscopic transabdominal preperitoneal inguinal hernia repair is feasible without higher risk of recurrences. In addition the fibrin fixation method may decrease postoperative neuralgia and reduce the incidence of postoperative seromas and hematomas.
