A total fundoplication is not an obstacle to esophageal emptying after heller myotomy for achalasia: results of a long-term follow up

Objective:The aim of this study was to evaluate the role and efficacy of a total 360° wrap, Nissen-Rossetti fundoplication, after esophagogastromyotomy in the treatment of esophageal achalasia. Summary Background Data:Surgery actually achieves the best results in the treatment of esophageal achalasia; the options vary from a short extramucosal esophagomyotomy to an extended esophagogastromyotomy with an associated partial fundoplication to restore the main antireflux barrier. A total 360° fundoplication is generally regarded as an obstacle to esophageal emptying. Matherials and Methods:Since 1992 to November 2003, a total of 195 patients (91 males, 104 females), mean age 45.2 years (range, 12–79 years), underwent laparoscopic treatment of esophageal achalasia. Intervention consisted of Heller myotomy and Nissen-Rossetti fundoplication with intraoperative endoscopy and manometry. Results:In 3 patients (1.5%), a conversion to laparotomy was necessary. Mean operative time was 75 ± 15 minutes. No mortality was observed. Overall major morbidity rate was 2.1%. Mean postoperative hospital stay was 3.6 ± 1.1 days (range, 1–12 days). At a mean clinical follow up of 83.2 ± 7 months (range, 3–141 months) on 182 patients (93.3%), an excellent or good outcome was observed in 167 patients (91.8%) (dysphagia DeMeester score 0–1). No improvement of dysphagia was observed in 4 patients (2.2%). Gastroesophageal pathologic reflux was absent in all the patients. Conclusions:Laparoscopic Nissen-Rossetti fundoplication after Heller myotomy is a safe and effective treatment of esophageal achalasia with excellent results in terms of dysphagia resolution, providing total protection from the onset of gastroesophageal reflux.

A multicenter phase II study of induction chemotherapy with FOLFOX-4 and cetuximab followed by radiation and cetuximab in locally advanced oesophageal cancer.

Background:Preoperative chemoradiotherapy (CRT) improves the survival of patients with oesophageal cancer when compared with surgery alone.Methods:We conducted a phase II, multicenter trial of FOLFOX-4 and cetuximab in patients with locally advanced oesophageal cancer (LAEC) followed by daily radiotherapy (180 cGy fractions to 5040 cGy) with concurrent weekly cetuximab. Cytokines levels potentially related to cetuximab efficacy were assessed using multiplex-bead assays and enzyme-linked immunosorbent assay at baseline, at week 8 and at week 17. Primary end point was complete pathological response rate (pCR).Results:In all, 41 patients were enroled. Among 30 patients who underwent surgery, a pCR was observed in 8 patients corresponding to a rate of 27%. The most frequent grade 3/4 toxicity was skin (30%) and neutropenia (30%). The 36-month survival rates were 85 and 52% in patients with pathological CR or PR vs 38 and 33% in patients with SD or PD.Conclusions:Incorporating cetuximab into a preoperative regimen for LAEC is feasible; no correlation between cytokines changes and patient outcome was observed. Positron emission tomography/computed tomography study even if influenced by the small number of patients appears to be able to predict patients outcome both as early and late metabolic response.

Laparoscopic Nissen-Rossetti fundoplication with routine use of intraoperative endoscopy and manometry: technical aspects of a standardized technique.

BackgroundSeveral different ways of fashioning a total fundoplication lead to different outcomes. This article addresses the technical details of the antireflux technique we adopted without modifications for all patients with GERD beginning in 1972. In particular it aims to discuss the relation between the mechanism of function of the wrap and the physiology of the esophagus.MethodsThe study population consisted of 380 patients affected by GERD with a 1-year minimum of follow-up who underwent laparoscopic Nissen-Rossetti fundoplication by a single surgeon.ResultsNo conversion to open surgery and no mortality occurred. Major complications occurred in 4 patients (1.1%). Follow-up (median 83 months; range: 1–13 years) was achieved in 96% of the patients. Ninety-two percent of the patients were satisfied with the results of the procedure and would undergo the same operation again. Postoperative dysphagia occurred in 3.5% of the patients, and recurrent heartburn was observed in 3.8%.ConclusionsLaparoscopic Nissen-Rossetti fundoplication with the routine use of intraoperative manometry and endoscopy achieved good outcomes and long-term patient satisfaction with few complications and side-effects. Appropriate preoperative investigation and a correct surgical technique are important in securing these results.

Laparoscopic treatment of Bochdalek hernia without the use of a mesh

Bochdalek hernia is a rare pathology. The preoperative diagnosis is difficult, and few reports are available regarding its treatment. Herein we report the case of a 25-year-old woman referred for symptoms of dyspepsia, dysphagia, and thoracic pain exacerbated by pregnancy. Preoperative radiography, EGD, and CT scan revealed a paraesophageal hiatal hernia. Laparoscopic exploration showed the complete thoracic migration of the stomach through a left posterolateral diaphragmatic foramen. The diagnosis of a Bochdalek hernia was then made. The diaphragmatic defect was repaired without inserting a prosthesis, using five separate non-reabsorbable stitches (Rieder technique). The procedure was completed with a Nissen-Rossetti fundoplication. The duration of the procedure was 150 min. Hospital stay was 12 days. There were no complications. Postoperative Gastrografin radiography of the esophagus and stomach showed a normal-shaped fundoplication and confirmed the subdiaphragmatic location of the stomach. We conclude that the laparoscopic approach represents the gold standard for the diagnosis and treatment of Bochdalek hernia and any associated complications.

The Over-The-Scope-Clip (OTSC) System is Effective in the Treatment of Chronic Esophagojejunal Anastomotic Leakage

IntroductionManagement of postoperative esophagojejunal anastomotic leakage after total gastrectomy represents a very challenging event. Surgical repair is difficult, and conservative treatment can predispose to more severe complications. Endoclips and self-expanding stents are useful endoscopic therapeutic options but present some drawbacks. The Over-The-Scope-Clip (OTSC) system has been shown to be appropriate to close acute small gastrointestinal perforations, but its use in the treatment of chronic leakage remains controversial.Case SeriesThe present series reports three consecutive chronic esophagojejunal anastomotic leaks successfully treated with OTSC. In all cases, clip application was simple, safe and effective, without early and late complications.DiscussionThe OTSC system may represent a new therapeutic option in the management of postoperative esophagojejunal anastomotic leakage.

Impact of long-acting octreotide in patients with early-stage MEN1-related duodeno-pancreatic neuroendocrine tumours

Somatostatin analogues (SSA) represent one of the main therapeutic option in patients affected with functioning well‐differentiated neuroendocrine tumours (NETs). There are no studies specifically focusing on NETs associated with Multiple Endocrine Neoplasia type 1 (MEN1).

Weekly Chemotherapy with Cisplatin and Paclitaxel and Concurrent Radiation Therapy as Preoperative Treatment in Locally Advanced Esophageal Cancer: A Phase II Study

ABSTRACT We evaluated the association of a weekly cisplatin (35 mg/mq) and paclitaxel (45 mg/mq) regimen with radiotherapy (46 Gy) as primary treatment in locally advanced esophageal cancer (LAEC). The main end point was the activity in terms of pathologic complete response (pathCR) rate. Thirty-three LAEC patients received chemoradiation therapy during weeks 1–6 followed by esophagectomy. A pathCR was observed in 10/33 patients; 20/33 and 3/33 patients showed PR and SD, respectively. The EUS maximal transverse cross sectional area reduction >50% significantly correlated with pathCR. Three-year survival rate was 35%. These results support the activity and mild toxicity of this regimen.

Foregut duplication of the stomach diagnosed by endoscopic ultrasound guided fine-needle aspiration cytology: case report and literature review

Gastric duplication cyst (GDC) with a pseudostratified columnar ciliatedepithelium is an uncommon malformation supposed to originate from a respiratorydiverticulum arising from the ventral foregut. Morphologic appearance of GDCs isvariable, depending on the density of their contents. GDCs are oftenmisdiagnosed as solid masses by imaging techniques, and as a consequence theymay be wrongly overtreated. We report our case of a 56-year-old man with a 5 cmhypoechoic mass of the gastroesophageal junction, incidentally detected bytransabdominal ultrasonography. Neither transabdominal ultrasonography normagnetic resonance clearly outlined the features of the lesion. The patientunderwent endoscopic ultrasound (EUS), which showed a hypoechoic mass arisingfrom the fourth layer of the anterior gastric wall, just below thegastroesophageal junction. According to EUS features, a diagnosis ofgastrointestinal stromal tumor was suggested. EUS-guided fine-needle aspirationcytology revealed a diagnosis of GDC with pseudostratified columnar ciliatedepithelium. We therefore performed an endoscopically-assisted laparoscopicexcision of the cyst.In conclusion, whenever a subepithelial gastric mass is found in the upper partof the gastric wall, a duplication cyst, although rare, should be considered. Inthis case, EUS-guided fine-needle aspiration cytology could provide acytological diagnosis useful to arrange in advance the more adequate surgicaltreatment.

Screening of pancreaticoduodenal endocrine tumours in patients with MEN 1: multidetector-row computed tomography vs. endoscopic ultrasound.

PurposeThe authors compared multidetector-row computed tomography (MDCT) and endoscopic ultrasound (EUS) in the identification of pancreaticoduodenal endocrine tumours (PETs) in patients with multiple endocrine neoplasia type 1 (MEN 1).Materials and methodsFourteen consecutive patients (eight men and six women, aged 26–54 years) with MEN 1 underwent MDCT performed with a 4- (n=5) or 64- (n=9) detector-row system and EUS done with a radial transducer (7.5–20 MHz) within 7–28 days of each other. Prior to MDCT examination, patients were given 750 cc of water and asked to lie down in the right lateral decubitus for 15 min. Multiphase MDCT images were acquired both before and after the injection of nonionic iodinated contrast material (2 cc/kg) at an injection rate of 4 ml/s, with technical parameters and scan delay varying in relation to the system used. Images were all reconstructed at 3-mm intervals for the three phases (arterial, pancreatic and portal) and evaluated on a dedicated workstation.ResultsMDCT detected a total of 25 PETs (3–18 mm) in nine patients. Of these lesions, nine were situated within the duodenal wall and 16 in either the pancreatic head (n=3), body (n=7), or tail (n=6). Three additional lesions were detected retrospectively after EUS imaging. Most (18/22, 81%) were hypervascular nodules, and four appeared as either hypoattenuating or cystic lesions. EUS detected a total of 32 PETs (2–18 mm) in 11 patients. Most lesions (29/32, 90%) appeared hypoechoic and were situated in the duodenal wall (n=15) or in either the pancreatic head (n=10), body (n=6) or tail (n=1).ConclusionsOur preliminary data indicate that MDCT is complementary to EUS in the identification of PETs in MEN-1 patients.RiassuntoObiettivoScopo del nostro lavoro è stato confrontare la tomografia computerizzata (TC) multistrato (TCMS) e l’eco-endoscopia (EUS) nella identificazione dei tumori endocrini pancreatico-duodenali (TEPD) in pazienti affetti da multiple endocrine neoplasia tipo 1 (MEN-1).Materiali e metodiQuattordici pazienti consecutivi (8 maschi, 6 femmine; 26–54 anni) affetti da MEN-1 sono stati sottoposti sia a TCMS, eseguita con 4 (n=5) o 64 file di detettori (n=9), che ad EUS eseguita con strumento radiale (7,5–20 MHz) entro 7–28 giorni. Gli esami TC sono stati acquisiti con tecnica multifasica previa distensione gastro-duodenale con acqua ed assunzione del decubito laterale destro (15 min), prima e dopo iniezione a bolo (4 ml/s) di mezzo di contrasto (MdC) iodato idro-solubile non ionico (2 cc/kg) con parametri tecnici e ritardi di scansione variabili in funzione del tipo di apparecchiatura. Le immagini sono state ricostruite con spessori identici (3 mm) per le 3 fasi (arteriosa, pancreatica e portale) ed analizzate su workstation dedicata.RisultatiAlla TCMS sono state riscontrate 16 lesioni nodulari (5–18 mm) a livello del pancreas (3 testa, 7 corpo e 6 coda) e 9 (3–7 mm) a carico della parete duodenale in 9 pazienti. Delle 25 formazioni nodulari, 22 sono state identificate prospetticamente (18 iper-, 4 ipo-ecogene o cistiche) e 3 alla luce del dato endoscopico. All’eco-endoscopia sono state riscontrate 32 formazioni nodulari (29 ipo-, 3 iso-ecogene) in 11 pazienti. Di queste, 17 (4–18 mm) a livello del pancreas (10 testa, 6 corpo, 1 coda) e 15 (2–12 mm) a livello della parete duodenale.ConclusioniLa TCMS rappresenta un utile complemento all’eco-endoscopia nella identificazione dei TEPD.

Clinical and instrumental parameters in patients with constipation and incontinence: their potential implications in the functional aspects of these disorders.

PurposeThe aims of this study were to evaluate several clinical and instrumental parameters in a large number of patients with constipation and incontinence as well as in healthy controls and discuss their potential implications in the functional aspects of these disorders.MethodsEighty-four constipated and 38 incontinent patients and 45 healthy controls were submitted to a protocol based on proctologic examination, clinico-physiatric assessment, and instrumental evaluation.ResultsConstipated and incontinent patients had significantly worse lumbar lordosis as well as lower rate in the presence of perineal defense reflex than controls. Constipated but not incontinent patients had a lower rate of puborectalis relaxation than controls. Furthermore, worse pubococcygeal tests and a higher rate of muscle synergies presence, either agonist or antagonist, were observed in both constipated and incontinent patients compared to controls.ConclusionsThis study has demonstrated strong correlations between physiatric disorders and the symptoms of constipation and incontinence. Further studies designed to demonstrate a causal relationship between these parameters and the success of a specific treatment of the physiatric disorders on the proctology symptoms are warranted.
