RESUMO

BACKGROUND: Single-incision laparoscopic surgery (SILS) is a new technique that aims to minimize abdominal wall trauma and improve cosmesis. Concerns have been raised about the risk of trocar-site hernia following SILS. This study aims to assess the risk of trocar-site hernia following SILS compared to conventional laparoscopic surgery, and investigate whether current evidence is conclusive. METHODS: We performed a systematic search of MEDLINE, AMED, CINAHL, CENTRAL, and OpenGrey. We considered randomized clinical trials comparing the risk of trocar-site hernia with SILS and conventional laparoscopic surgery. Pooled odds ratios with 95% confidence intervals (CI) were calculated using the Mantel-Haenszel method. Trial sequential analysis using the Land and DeMets method was performed to assess the possibility of type I error and compute the information size. RESULTS: Twenty-three articles reporting a total of 2471 patients were included. SILS was associated with higher odds of trocar-site hernia compared to conventional laparoscopic surgery (odds ratio 2.37, 95% CI 1.25-4.50, p = 0.008). There was no evidence of between-study heterogeneity or small-study effects. The information size was calculated at 1687 patients and the Z-curve crossed the O'Brien-Fleming α-spending boundaries at 1137 patients, suggesting that the evidence of higher risk of trocar-site hernia with SILS compared to conventional laparoscopic surgery can be considered conclusive. CONCLUSIONS: Single-incision laparoscopic procedures through the umbilicus are associated with a higher risk of trocar-site hernia compared to conventional laparoscopic surgery.

RESUMO

PURPOSE: The purpose of this study is to review the latest evidence on operative and perioperative management of patients with groin hernia. METHODS: A literature review of medical databases was undertaken. Recent scientific evidence provided by quality reports was selected and discussed critically. RESULTS: The Shouldice repair results in low recurrence rates compared to other tissue reconstructions. However, mesh repairs are superior to tissue reconstruction in terms of recurrence. Lichtenstein's technique remains the gold standard, with low incidence of hernia recurrence and minimal morbidity. Endoscopic techniques have been popularized during the past decades, as alternative approaches to open surgery. Both transabdominal preperitoneal repair (TAPP) and the totally extraperitoneal repair (TEP) are effective in the treatment of groin hernia, although the steep learning curve precludes popularization and may account for increased perioperative morbidity. CONCLUSIONS: Groin hernia surgery remains an evolving field of investigation. Mesh application remains the mainstay of durable results. Individual patient factors and hernia characteristics need to be taken into account when considering the most appropriate surgical practice.

RESUMO

AIM: Bariatric surgery is highly effective for the treatment of obesity in individuals without (OB1) and in those with type 2 diabetes (T2D2). However, whether bariatric surgery triggers similar or distinct molecular changes in OB and T2D remains unknown. Given that individuals with type 2 diabetes often exhibit more severe metabolic deterioration, we hypothesized that bariatric surgery induces distinct molecular adaptations in skeletal muscle, the major site of glucose uptake, of OB and T2D after surgery-induced weight loss. METHODS: All participants (OB, n = 13; T2D, n = 13) underwent detailed anthropometry before and one year after the surgery. Skeletal muscle biopsies were isolated at both time points and subjected to transcriptome and methylome analyses using a comprehensive bioinformatic pipeline. RESULTS: Before surgery, T2D had higher fasting glucose and insulin levels but lower whole-body insulin sensitivity, only glycemia remained higher in T2D than in OB after surgery. Surgery-mediated weight loss affected different subsets of genes with 2,013 differentially expressed in OB and 959 in T2D. In OB differentially expressed genes were involved in insulin, PPAR signaling and oxidative phosphorylation pathways, whereas ribosome and splicesome in T2D. LASSO regression analysis revealed distinct candidate genes correlated with improvement of phenotypic traits in OB and T2D. Compared to OB, DNA methylation was less affected in T2D in response to bariatric surgery. This may be due to increased global hydroxymethylation accompanied by decreased expression of one of the type 2 diabetes risk gene, TET2, encoding a demethylation enzyme in T2D. CONCLUSION: OB and T2D exhibit differential skeletal muscle transcriptome responses to bariatric surgery, presumably resulting from perturbed epigenetic flexibility.

RESUMO

BACKGROUND: Trocar-associated visceral injuries are rare but potentially fatal complications of laparoscopic access. More commonly, abdominal wall bleeding occurs, which usually requires hemostatic measures and prolongs operative time. Blunt-tipped trocars have been postulated to carry a lower risk of abdominal wall bleeding and intra-abdominal injuries. The aim of the present systematic review and meta-analysis was to comparatively evaluate the relative risks of abdominal wall bleeding, visceral injuries, and overall complications with the use of bladed and blunt-tipped laparoscopic trocars. METHODS: The databases of Medline, EMBASE, and the Cochrane Central Register of Randomized Trials were searched to identify randomized studies that compared trocar-associated complications with the use of blunt and bladed trocars. Primary outcome measure was the relative risk of abdominal wall trocar site bleeding, and secondary outcome measures included visceral injuries and overall complications. Outcome data were pooled and combined overall effect sizes were calculated using the fixed- or random-effects model. RESULTS: Eight eligible randomized trials were identified; they included 720 patients with a median Jadad score of 4. The incidence of abdominal wall bleeding for the blunt and the bladed trocar group was 3 and 9 %, respectively [odds ratio (OR) 0.42, 95 % confidence interval (CI) 0.21-0.88]. Trocar-associated morbidity rate, excluding bleeding events of the abdominal wall, was documented at 0.2 and 0.7 % of the blunt and the bladed trocar arm, respectively (OR 0.43, 95 % CI 0.06-2.97). The overall trocar-associated morbidity rate was 3 % in the blunt trocar group and 10 % in the bladed trocar group (OR 0.38, 95 % CI 0.19-0.77). CONCLUSIONS: Reliable data support a lower relative risk of trocar site bleeding and overall complications with blunt laparoscopic cannulas than bladed trocars. Transition to blunt trocars for secondary cannulation of the abdominal wall is thus strongly recommended. Larger patient populations are required to estimate the relative risk of visceral injuries.

RESUMO

BACKGROUND AND OBJECTIVES: Laparoscopic treatment of perforated peptic ulcer (PPU) has been introduced as an alternative procedure to open surgery. It has been postulated that the minimally invasive approach involves less operative stress and results in decreased morbidity and mortality. METHODS: We conducted a meta-analysis of randomized trials to test this hypothesis. Medline, EMBASE, and the Cochrane Central Register of Randomized Trials databases were searched, with no date or language restrictions. RESULTS: Our literature search identified 4 randomized trials, with a cumulative number of 289 patients, that compared the laparoscopic approach with open sutured repair of perforated ulcer. Analysis of outcomes did not favor either approach in terms of morbidity, mortality, and reoperation rate, although odds ratios seemed to consistently support the laparoscopic approach. Results did not determine the comparative efficiency and safety of laparoscopic or open approach for PPU. CONCLUSION: In view of an increased interest in the laparoscopic approach, further randomized trials are considered essential to determine the relative effectiveness of laparoscopic and open repair of PPU.

RESUMO

INTRODUCTION: Laparoscopic techniques have induced a tremendous revolution in the field of general surgery. Recent multicenter trials have demonstrated similar patient-oriented and oncologic outcomes for laparoscopic colon and rectal resections compared with their open counterparts. Meanwhile, robotic technology has gradually entered the field of general surgery, allowing increased dexterity, improved operative view, and optimal ergonomics. The objective of this study was to review the current status of clinical robotic applications in colorectal surgery. METHODS: A systematic review of the literature using the PubMed search engine was undertaken to identify relevant articles. The keywords used in all possible combinations were: surgical robotics, robotic surgery, computer-assisted surgery, colectomy, sigmoid resection, sigmoidectomy, and rectal resection. RESULTS: Thirty-nine case series or comparative nonrandomized studies were identified. A specific interest for robot-assisted rectal surgery during the past few years was recorded in the literature. The retrieved articles included 13 ileocecal resections, 220 right colectomies, 190 left colectomies/sigmoid resections, 440 anterior resections, 149 abdominoperineal/intersphincteric resections, and 11 total/subtotal colectomies. The clinical application of the da Vinci robotic system in right and left/sigmoid colectomies yielded satisfactory results in terms of open conversion (1.1 and 3.8%, respectively) and operative morbidity (13.4 and 15.1%, respectively). Robot-assisted anterior resection was accompanied by a considerably low conversion rate (0.4%), morbidity (9.7%), and adequate number of harvested lymph nodes (14.3, mean). CONCLUSIONS: Robotic applications in colorectal surgery are feasible with low conversion rates and favorable morbidity. Further studies are required to evaluate its oncologic and patient-oriented outcomes.

RESUMO

BACKGROUND: Although symptom outcomes following laparoscopic fundoplication have been adequately evaluated in the past, comparative subjective data of laparoscopic Nissen and Toupet fundoplications are scarce. Multichannel intraluminal impedance monitoring (MII) has not been used so far for comparison of objective data. METHODS: One hundred patients with documented chronic gastroesophageal reflux disease (GERD) were randomly allocated to either floppy Nissen fundoplication (group I, n = 50) or Toupet fundoplication (group II, n = 50). Gastrointestinal Quality of Life Index (GIQLI), symptom grading, esophageal manometry, and MII data were documented preoperatively and 3 months after surgery. Subjective and objective outcome data were compared to those of healthy individuals. RESULTS: Symptom intensity was significantly more severe and GIQLI showed impairment in the examined patient population compared to healthy controls. Both procedures resulted in a significant improvement in GIQLI and GERD symptoms (p < 0.01). Dysphagia improved significantly only in group II, while cough, asthma, and distortion of taste improved significantly in both groups. Hoarseness symptoms showed some degree of improvement in both groups but reached statistical significance only in group I. Postoperatively, bowel symptoms partly increased and the ability to belch decreased in both groups (p < 0.05). Comparison of postoperative GIQLI and symptom scores showed no significant difference between the two groups, except for the ability to belch, which was more impaired after Nissen fundoplication. Both procedures resulted in a significant improvement in lower esophageal sphincter (LES) pressure; however, the improvement was greater in group I than in group II. MII data showed more reflux control after Nissen, but the differences between the procedures were not significant. CONCLUSIONS: Both procedures equally improve quality of life and GERD symptoms. Bowel symptoms may increase after both procedures at the 3-month follow-up. Manometry and MII data favor Nissen fundoplication, but dysphagia and the inability to belch are more common compared to Toupet fundoplication.

RESUMO

BACKGROUND: Incorporation of advanced laparoscopic procedures in the practice of institutions without respective experience is a significant impediment in the dissemination of minimally invasive techniques. On-site mentoring programs carry several cost-related and practical constraints. Telementoring has emerged as a practical and cost-effective alternative mentoring tool. The present study aimed to review the pertinent literature on telementoring applications in laparoscopic general surgery. METHODS: A systematic review using the Medline database was performed. Articles reporting on clinical experience with telementoring applications in general surgery were included. Variations in methodology, study design, and operative procedures precluded cumulative outcome evaluation. Instead, a critical appraisal of current evidence was undertaken. RESULTS: Seventy-five articles were identified in the primary search, and ten studies were considered eligible. No randomized studies comparing on-site mentoring with telementoring were identified. The included studies reported on a total of 96 laparoscopic telementored procedures: 50 cholecystectomies, 23 colorectal resections, 7 fundoplications, 9 adrenalectomies, 6 hernia repairs, and 2 splenectomies. Completion of remotely assisted procedures was feasible in the vast majority of cases, whereas technical difficulties included video and audio latency with low transfer rates (<128 kbps) and inadequate guidance regarding the correct plane for dissection. CONCLUSION: Current evidence supports the feasibility and safety of telementoring programs in general surgery. Their clinical effectiveness as teaching alternatives to traditional mentoring programs remains to be further evaluated.

RESUMO

BACKGROUND: Endoscopic antireflux techniques have emerged as alternative therapies for gastroesophageal reflux disease (GERD). Endoscopic plication receives continuing interest as an effective and safe procedure. This treatment option has not been the subject of comparison with well-established operative therapies to date. The present study aimed at comparatively evaluating the effectiveness of endoscopic plication and laparoscopic fundoplication in terms of quality of life and symptom control. METHODS: Between October 2006 and April 2010, 60 patients with documented GERD were randomly assigned to undergo either endoscopic plication or laparoscopic fundoplication. Quality-of-life scores and symptom grading were recorded before treatment and at 3- and 12-month follow-up. Outcomes were compared with the statistical significance set at a p value of 0.05. RESULTS: Twenty-nine patients from the endoscopic group and 27 patients from the operative group were available at follow-up. Quality-of-life scores showed a substantial and similar increase for both groups after treatment. Symptoms of heartburn (p < 0.02), regurgitation (p < 0.004), and asthma (p = 0.03) were significantly improved in the endoscopic group, whereas laparoscopic fundoplication was more effective in controlling symptoms of heartburn (p < 0.01) and regurgitation (p < 0.05) compared to the endoscopic procedure. CONCLUSIONS: Endoscopic plication and laparoscopic fundoplication resulted in significant symptom improvement with similar quality-of-life scores in a selected patient population with GERD, whereas operative treatment was more effective in the relief of heartburn and regurgitation at the expense of higher short-term dysphagia rates.

RESUMO

PURPOSE: The objective of the present study was to review the pertinent literature and analyze the evidence for and against the use of mesh for hiatal hernia repair, with a focus on the effects on recurrence and postoperative dysphagia. METHODS: A literature search was performed between January 1990 and March 2010. Studies were considered for inclusion, provided (1) they comprised a series of at least 20 patients, (2) they documented a follow-up period of at least 6 months, (3) they reported on the outcome as expressed by hernia recurrence rates, and (4) they reported on type of mesh material, hiatal closure, and antireflux surgery. RESULTS: Twenty-three articles enrolling a cumulative number of 1,446 patients fulfilled the inclusion criteria. Polypropylene meshes seem to be associated with low recurrence rates (0-22.7%, median 1.9%) and acceptable dysphagia rates (0-21.7%, median 3.9%). Higher dysphagia rates after polytetrafluoroethylene (PTFE) and expanded PTFE (ePTFE) mesh hiatoplasty have been recorded (15.5-34.3%). Even though the use of novel biologic implants for hiatal repair is still in its infancy, the existing results from clinical research are promising. CONCLUSIONS: Polypropylene meshes seem to provide durable results with low dysphagia rates. Unacceptably high recurrence rates for PTFE/ePTFE meshes have been reported. Biologic implant engineering represents a promising field in hiatal hernia surgery.

RESUMO

BACKGROUND: Abdominal aortic aneurysms (AAAs) and abdominal wall hernias represent chronic degenerative conditions. Both aortic aneurysms and inguinal hernias share common epidemiologic features, and several investigators have found an increased propensity for hernia development in patients treated for aortic aneurysms. Chronic inflammation and dysregulation in connective tissue metabolism constitute underlying biological processes, whereas genetic influences appear to be independently associated with both disease states. A literature review was conducted to identify all published evidence correlating aneurysms and hernias to a common pathology. METHODS: PubMed/Medline was searched for studies investigating the clinical, biochemical, and genetic associations of AAAs and abdominal wall hernias. The literature was searched using the MeSH terms "aortic aneurysm, abdominal," "hernia, inguinal," "hernia, ventral," "collagen," "connective tissue," "matrix metalloproteinases," and "genetics" in all possible combinations. An evaluation, analysis, and critical overview of current clinical data and pathogenic mechanisms suggesting an association between aneurysms and hernias were undertaken. RESULTS: Ample evidence lending support to the clinical correlation between AAAs and abdominal wall hernias exists. Pooled analysis demonstrated that patients undergoing aortic aneurysm repair through a midline abdominal incision have a 2.9-fold increased risk of developing a postoperative incisional hernia compared with patients treated for aortoiliac occlusive disease (odds ratio, 2.86; 95% confidence interval, 1.97-4.16; P < .00001), whereas the risk of inguinal hernia was 2.3 (odds ratio, 2.30; 95% confidence interval, 1.52-3.48; P < .0001). Emerging evidence has identified inguinal hernia as an independent risk factor for aneurysm development. Although mechanisms of extracellular matrix remodeling and the imbalance between connective tissue degrading enzymes and their inhibitors instigating inflammatory responses have separately been described for both disease states, comparative studies investigating these biological processes in aneurysm and hernia populations are scarce. A genetic predisposition has been documented in familial and observational segregation studies; however, the pertinent literature lacks sufficient supporting evidence for a common genetic basis for aneurysm and hernia. CONCLUSIONS: Insufficient data are currently available to support a systemic connective tissue defect affecting the structural integrity of the aortic and abdominal wall. Future investigations may elucidate obscure aspects of aneurysm and hernia pathophysiology and create novel targets for pharmaceutical and gene strategies for disease prevention and treatment.

RESUMO

BACKGROUND: Laparoscopic techniques induced a tremendous revolution in surgery of the biliary tract, mainly due to improved results compared with the open approach and secondary because of their cosmetic advantage. A trend toward even more minimally invasive approaches has led to techniques of single-incision and natural orifice laparoscopic surgery. Because the evaluation of single-incision laparoscopic cholecystectomy (SILC) is rather fragmentary by single-institution small patient series, this article intends to examine the success and the risks of the technique, and attempts to determine its potential limitations. METHODS: A systematic review of the literature was performed to identify relevant articles. Studies enrolling at least ten patients who underwent SILC and reporting on analytical complication data were considered for inclusion. RESULTS: The literature search identified 29 studies, which included a total of 1,166 patients. Success and complication rates were 90.7% and 6.1%, respectively. Mean adjusted operative time was 70.2 min and mean adjusted hospital stay was 1.4 days. Analysis of outcome exhibited higher complication rates for studies with a mean patient age older than 45 years (p=0.04), and higher operative time for studies with a mean body mass index>30 kg/m2 (83.4 vs. 74.5 min) and female percentage lower than 70% (78.7 vs. 68.5 min). Acute cholecystitis as inclusion criterion was a factor for technical failure (success rate 59.9 vs. 93.0%, p=0.005) and resulted in an increase of operative time (78.1 vs. 70.6 min). Suture suspension of the gallbladder yielded significantly lower complication rates compared with instrument usage (3.3 vs. 13.3%, p<0.0001). CONCLUSIONS: The clinical application of SILC exhibited satisfactory results. Cases of acute cholecystitis and older patients should be approached with caution, whereas improvement of the instrumentation is necessary.

RESUMO

BACKGROUND: Intrathoracic wrap migration is the most frequent morphological anatomic reason for failure of laparoscopic antireflux surgery (LARS). This study investigates whether the size of the esophageal hiatus is a factor in reherniation after LARS with mesh hiatoplasty and after primary failed hiatal closure. METHODS: Fifty-four patients who underwent a laparoscopic 270° Toupet fundoplication with simple sutured crura and posterior onlay of Parietex mesh prosthesis between October 2003 and June 2008 were evaluated with respect to the occurrence of postoperative intrathoracic wrap migration/reherniation. Indication for mesh hiatoplasty was a hiatus with a hiatal surface area (HSA) of at least 5.60 cm(2) or slippage after the first LARS. The integrity of repair was assessed using a barium swallow test. Cinematography was performed at a median of 25.6 months (3-63 months after operation) and was completed in 49 of 54 patients (90%). Follow-up was completed in 24 patients who underwent primary LARS (group A) and 25 patients who underwent a laparoscopic refundoplication (group B). RESULTS: In group A, the occurrence of postoperative wrap reherniation was diagnosed in 20.8% of the patients, compared to 40% in group B. In both groups only one patient with recurrent hiatal hernia was symptomatic. In group A, patients who developed a recurrent hernia had a larger HSA than patients without postoperative reherniation. There was a huge difference in the size of the HSA between symptomatic and asymptomatic patients with reherniation. In comparison, group B patients had HSA of similar size in all described cases. CONCLUSION: In primary intervention, recurrence of hiatal hernia is more likely the larger the HSA is. The size of the hiatus is a major contributing factor to the possibility of reherniation. After failed primary hiatal closure, the size of the hiatal defect is no marker for the possibility of reherniation.

RESUMO

The snake has served as a medical emblem for more than 2400 years, since its association with the ancient Greek god of medicine and healing, Asclepius, in the 4th century BC. Its symbolic background can be traced further back to the worship of gods of earth's blossom in ancient Egypt and earth-related deities of the archaic period of Greek antiquity. It is featured entwined around a staff of knowledge and wisdom in most anaglyphs depicting Asclepius. The snake was impressed in the Old and the New Testament as well as in the Christian tradition as a symbol of sin, rejuvenation, death, resurrection, asthenia, and therapy. It is postulated that the double-snake motif was reintroduced by Renaissance philosophers as a medical emblem due to the symbolic connections of Hermes with deliverance and redemption. However, its use during the last two centuries seems to lack substantial historical background. The historical, mythological, and traditional retrospection of the snake's symbolism validates its appropriateness in the health-care field.

RESUMO

Hippocratic Oath indicates a prevailing ethos rather than a professional approach, and it is still regarded as the cornerstone and foundation of the medical profession. Medicine in Ancient Greece was strongly influenced by the values of classical philosophy as introduced by its main representatives: Plato and Aristotle. Hippocrates himself has been recognized not only as a pioneering physician, but also as an outstanding philosopher. In his writings, he claimed that "the physician must insert wisdom in medicine" and denounced the technocratic aspect of the medical profession. The Hippocratic Oath constitutes a synopsis of the moral code of Ancient Greek medicine and contributes to the stabilization of the tri-part relationship among the physician, the patient, and the illness, as described by Hippocrates. The harmony of this interactive triangle has been deranged by several factors, such as technological evolution, public media, and cost-effective modalities with multiple consequences. In these terms, the reevaluation of the Hippocratic Oath and its time-enduring messages seems essential to reinstate the relationship between the physician and the patient under a new philosophico-medical prism.

RESUMO

INTRODUCTION: Early laparoscopic rectosigmoid resection for acute complicated diverticulitis may avoid secondary hospital stay and stoma-related complications. Benefits of elective surgical therapies could advance the early laparoscopic approach for acute sigmoid diverticulitis. MATERIAL AND METHODS: From January 2006 to April 2007, a total of 26 patients underwent laparoscopic rectosigmoid resection for acute complicated diverticulitis. Laparoscopy was performed after initial antibiotic treatment and within 10 days after admission to the hospital. Characteristics and outcome were recorded prospectively. RESULTS: Mean age for 13 females was 63.3 years (range, 45-78 years) and for 13 males was 56.2 years (range, 37-76 years). A body mass index of >or=25.0 kg/m(2) was registered in 20/26 patients. Mean operative time was 122.1 min (range, 60-192 min) and mean length of the sigmoid specimen was 179 mm (range, 120-240 mm). Mean time of recovery after surgery was 7.9 days (range, 6-12 days). Operative-related complications were two wound seromas. No anastomotic leak was observed. One month postoperatively, a condition-specific quality of life questionnaire assessed significant increase of the general score index, emotional status, and medical treatment. CONCLUSION: This prospective study demonstrates the feasibility of an early laparoscopic rectosigmoid resection for acute complicated diverticulitis with an excellent outcome and a low morbidity rate.

RESUMO

Morbid obesity is a recognized risk factor for gastrointestinal cancer. Little is known about pancreatic cancer developing after gastric bypass surgery or about surgery for this type of tumor following bariatric surgery. This report describes a case of pancreatic head cancer identified 3 months after laparoscopic sleeve gastrectomy for morbid obesity. During routine follow-up, mild abdominal pain and elevated pancreatic enzymes prompted computed tomography, which revealed mild edematous pancreatitis. Hyperbilirubinemia developed, and magnetic resonance imaging showed a pancreatic head tumor. CA19-9 was elevated. After a pylorus-preserving pancreatic head resection, the postoperative course was uneventful. The patient received adjuvant chemotherapy. Unfortunately, at the time of writing (9 months postoperatively), a local recurrence and hepatic metastases were diagnosed. Patients treated with bariatric surgery who develop new symptoms or report constant mild symptoms should be evaluated using endoscopy and radiomorphological imaging. Interdisciplinary obesity treatment can then offer significant benefits for the patient, particularly in the case of pancreatic cancer, which is still difficult to diagnose. In addition, there is a need for epidemiological studies of patients who undergo bariatric surgery and subsequently develop cancer.

RESUMO

HYPOTHESIS: Prosthetic crural closure does not adversely influence esophageal body motility. In most patients, postoperative increased dysphagia resolves spontaneously during the first months after surgery. DESIGN: Prospective randomized trial. We compared patients who underwent laparoscopic Nissen fundoplication with simple sutured hiatal closure and those who underwent laparoscopic Nissen fundoplication with prosthetic hiatal closure. SETTING: University-affiliated community hospital. PATIENTS: Forty consecutive patients who underwent laparoscopic Nissen fundoplication for gastroesophageal reflux disease. INTERVENTIONS: A 360 degrees Nissen fundoplication with simple sutured crura (n = 20; nonmesh group) vs the same procedure with posterior 1 x 3-cm polypropylene onlay mesh prosthesis (n = 20; mesh group). MAIN OUTCOME MEASURES: Recurrences; postoperative dysphagia rate; localization, length, and pressure of the lower esophageal sphincter (LES); results of 24-hour pH monitoring; esophageal body motility; peristalsis; and esophageal amplitude of contraction and interrupted waves. RESULTS: Preoperatively, both groups had pathological LES pressure and DeMeester scores. These values improved significantly (P < .01) after surgery and remained stable at 1 year after surgery. Patients in the nonmesh group had a significantly lower LES pressure 1 year after surgery compared with those in the mesh group. There were no significant differences in postoperative mean LES length (4.1 vs 3.8 cm), LES relaxation (93.4% vs 92.4%), and intra-abdominal LES length (2.1 vs 2.1 cm). Patients in the mesh group had fewer simultaneous waves and interrupted waves 1 year after surgery, but the difference between groups was not significant. There were no significant differences in interrupted waves and amplitude of contraction between groups 1 year after surgery. CONCLUSION: Laparoscopic Nissen fundoplication with prosthetic crural closure does not impair postoperative esophageal body motility compared with laparoscopic Nissen fundoplication with simple suture hiatal closure, although it is associated with a higher rate of short-term dysphagia.

RESUMO

During recent years, laparoscopic splenectomy has shown to be a safe and effective surgical approach in patients with hematologic disorders requiring spleen removal. Especially in cases with splenomegaly, the laparoscopic approach results in a shorter hospital stay and faster recovery of the patients. Due to the increasing experience in laparoscopy, this approach also is emerging to be a therapeutic option in patients with blunt abdominal trauma with splenic rupture or hematoma. We report the case of an 80-year-old female patient who underwent laparoscopic splenectomy for symptomatic splenomegaly due to non-hodgkin Lymphoma in combination with stable traumatic splenic hematoma after blunt abdominal trauma.

RESUMO

BACKGROUND: One of the most frequent complications after laparoscopic antireflux surgery is estimated to be the intrathoracic herniation of the wrap into the chest. Therefore, in up to 5% of patients, revisional surgery is necessary. HYPOTHESIS: Patients who undergo laparoscopic refundoplication for postoperative intrathoracic wrap herniation using a circular polypropylene mesh for hiatal closure have a good to excellent functional outcome, during a complete follow-up of 1 year. DESIGN: Prospective nonrandomized trial of a consecutive sample. SETTING: University-affiliated community hospital. PATIENTS: Twenty-four patients undergoing laparoscopic refundoplication for persistent or recurrent symptoms of gastroesophageal reflux disease as a result of postoperative intrathoracic wrap migration. INTERVENTION: All patients underwent laparoscopic refundoplication with a circular polypropylene mesh for hiatal closure. MAIN OUTCOME MEASURES: Recurrences, complications, postoperative lower esophageal sphincter pressure, DeMeester score, esophagogastroduodenoscopy results, and barium swallow results. RESULTS: All refundoplications were completed laparoscopically. There were no intraoperative complications. Twenty-one patients underwent laparoscopic Nissen fundoplication; in 3 patients, a laparoscopic Toupet fundoplication was performed. Previous antireflux procedures included an open Nissen fundoplication (n = 5), a laparoscopic Nissen fundoplication (n = 15), and a laparoscopic Toupet fundoplication (n = 4). Postoperatively, one patient had severe dysphagia and had to undergo pneumatic dilatation once. During a follow-up of 1 year after surgery, no patient developed a recurrent hiatal hernia, with or without intrathoracic wrap herniation. The mean lower esophageal sphincter pressure increased significantly (P<.01) at 3 months (12.2 mm Hg) and 1 year (11.9 mm Hg) after refundoplication. The mean DeMeester score decreased significantly (P<.01) from 50.5 points preoperatively to 16.0 points at 3 months and 14.7 points at 1 year after refundoplication. CONCLUSION: Laparoscopic refundoplication with prosthetic hiatal closure is a safe and effective procedure for preventing recurrent intrathoracic wrap herniation, with good to excellent functional outcome for a complete follow-up of 1 year.
