Same-day discharge in benign esophageal surgery: a prospective cohort study.

Day-case esophageal surgery has been demonstrated to be safe in small prospective cohorts and only for laparoscopic fundoplication. The aims of this study are to assess the feasibility and safety of a large series of esophageal day-case surgeries, including laparoscopic Nissen fundoplication (LNF), Zenker diverticulectomy (ZD), and laparoscopic Heller myotomy (LHM) and to compare the outcomes among three procedures.This was a prospective, observational study of selected patients who underwent day-case LNF, ZD, and LHM between 2003 and 2013. Postoperative outcomes, the patients' satisfaction, and functional results were evaluated with dedicated scores and compared.Of the 427 patients who underwent surgery for those indications during the study period, 168 (39.3%) eligible patients underwent day-case procedures (134 LNF, 14 LHM, and 20 ZD). The overnight unplanned admission rate was 16.2% and was similar among the groups (P = 0.681). Ten patients were readmitted during the first postoperative week because of dysphagia (n = 6, all in the LNF group), flu-like syndrome (n = 1), and secondary perforation (n = 3, all in the LHM group). The unplanned seven-day readmission rate was significantly higher in the LHM group than in the ZD and LNF groups (P = 0.042). The 30-day rates of unplanned readmission and consultation were 8.9% (P = 0.300) and 4.8%, respectively. At follow-up, 87.5% of the patients were satisfied with day-case treatment, and the functional results were good for 81.4% of the patients.Day-case esophageal surgery is feasible for LNF and seems to be feasible for ZD. Safety criteria have not yet been met for LHM, requiring further adaptations.

Patterns of recurrence in early-stage oesophageal cancer after chemoradiotherapy and surgery compared with surgery alone.

BACKGROUND: Patterns of disease recurrence in patients with oesophageal cancer following treatment with neoadjuvant chemoradiotherapy and surgery (nCRTS) or surgery alone are poorly reported. An understanding of patterns of disease recurrence is important for subsequent treatment planning. METHODS: An analysis was undertaken of patterns of disease recurrence from a phase III multicentre randomized trial (FFCD9901) comparing nCRTS with surgery alone in patients with stage I and II oesophageal cancer. RESULTS: Some 170 patients undergoing surgical resection were included in the study. R0 resection rates were similar in the two groups: 94 per cent following nCRTS versus 92 per cent after surgery alone (P = 0·749). After a median follow-up of 94·2 months, recurrent disease was found in 39·4 per cent of the overall cohort (31 per cent after nCRTS versus 47 per cent following surgery alone; P = 0·030). Locoregional recurrence was diagnosed in 41 patients (17 versus 30 per cent respectively; P = 0·047) and distant metastatic recurrence in 47 (23 versus 31 per cent respectively; P = 0·244). Metastatic recurrence was more frequent in patients with adenocarcinoma than in those with squamous cell cancer (40 versus 23·1 per cent respectively; P = 0·032). ypT0 N0 category was associated with prolonged time to mixed locoregional and metastatic recurrence (P = 0·009), and time to locoregional (P = 0·044) and metastatic (P = 0·055) recurrence. In multivariable analysis, node-positive disease predicted both locoregional (P = 0·001) and metastatic (P < 0·001) recurrence. CONCLUSION: Locoregional disease control following nCRTS indicated a local field effect not related solely to completeness of resection. pN+ disease was strongly predictive of time to locoregional and metastatic disease recurrence.

Day-case versus inpatient laparoscopic fundoplication: outcomes, quality of life and cost-analysis.

BACKGROUND: Day-case laparoscopic Nissen-Rossetti fundoplication (LF) has been demonstrated to be safe in small, prospective cohorts. The purpose of the study was to compare postoperative course, functional results, quality of life, and healthcare costs in patients undergoing LF in a day-case surgical unit with same-day discharge and patients undergoing LF as an inpatient. METHODS: All consecutive patients in our department who underwent a primary LF for symptomatic uncomplicated gastroesophageal reflux disease from 2004 to 2011 were entered into a prospective database (n = 292). From 101 same-day discharge patients (day-case group), control inpatient procedures were randomly matched by age, gender, body mass index, American Society of Anesthesiologists classification, and presence of a hiatal hernia (inpatient group, n = 101). RESULTS: No postoperative deaths occurred and postoperative morbidity occurred in 9.4% of patients. When comparing day-case and inpatient groups, postoperative morbidity rates were 9.9 vs. 8.9% (p = 0.81) with median hospital stays and readmission rates of 1 vs. 4 days (p < 0.001) and 7.9 vs. 0% (p < 0.001), respectively. Gastrointestinal Quality of Life Index was significantly enhanced due to surgery (p < 0.001) and comparable in the two groups. Estimated direct healthcare costs per patient were 2,248 euros in the day-case group vs. 6,569 euros in the inpatient group (p < 0.001), equivalent to a cost saving of 3,921 euros. CONCLUSIONS: Day-case and inpatient approaches after LF give similar results in terms of postoperative mortality and morbidity, functional outcomes and quality of life, with a substantial cost saving in favor of a day-case procedure.

Effects of hybrid minimally invasive oesophagectomy on major postoperative pulmonary complications.

BACKGROUND: Morbidity after oesophageal cancer surgery remains high, mainly due to major postoperative pulmonary complications (MPPCs). The aim of this study was to test the hypothesis that hybrid minimally invasive oesophagectomy (HMIO) decreases the 30-day MPPC rate without compromising oncological outcomes. METHODS: Consecutive patients undergoing curative oesophagectomy for cancer by laparoscopic gastric mobilization and open thoracotomy (HMIO) between January 2004 and December 2009 were matched to randomly selected patients undergoing a totally open approach during the same study interval. Matching variables were age, sex, cancer stage, location of the primary tumour, histological subtype, American Society of Anesthesiologists grade, malnutrition, neoadjuvant chemoradiation and epidural analgesia. RESULTS: MPPCs at 30 days were significantly less frequent after HMIO compared with open surgery (15·7 versus 42·9 per cent; P < 0·001). Postoperative in-hospital mortality and overall morbidity rates were 4·3 and 47·5 per cent respectively, again significantly lower in the HMIO group: 1·4 versus 7·1 per cent (P = 0·018) and 35·7 versus 59·3 per cent (P < 0·001). In multivariable analysis, HMIO, adenocarcinoma subtype, epidural analgesia and surgery after 2006 were independent protective factors against MPPCs, and HMIO was independently protective against acute respiratory distress syndrome (ARDS). Lymph node yields and survival were similar in the two groups. CONCLUSION: HMIO for oesophageal cancer, using laparoscopic gastric mobilization and open right thoracotomy, offered a substantial and independent protective effect against MPPCs, including ARDS, without compromising oncological outcomes.

A systematic review of surgical site infections following day surgery: a frequentist and a Bayesian meta-analysis of prevalence.

BACKGROUND: Since 1990, several studies have focused on safety and patient satisfaction in connection with day surgery. However, to date, no meta-analysis has investigated the overall prevalence of surgical site infections (SSI). AIM: To estimate the overall prevalence of SSI following day surgery, regardless of the type of surgery. METHOD: A systematic review and a meta-analysis of the prevalence of SSI following day surgery, regardless of the type of surgery, was conducted, seeking all studies before June 2016. A pooled random effects model using the DerSimonian and Laird approach was used to estimate overall prevalence. A double arcsine transformation was used to stabilize the variance of proportions. After performing a sensitivity analysis to validate the robustness of the method, univariate and multi-variate meta-regressions were used to test the effect of date of publication, country of study, study population, type of specialty, contamination class, time of postoperative patient visit after day surgery, and duration of hospital care. FINDINGS: Ninety articles, both observational and randomized, were analysed. The estimated overall prevalence of SSI among patients who underwent day surgery was 1.36% (95% confidence interval 1.1-1.6), with a Bayesian probability between 1 and 2% of 96.5%. The date of publication was associated with the prevalence of SSI (coefficient -0.001, P = 0.04), and the specialty (digestive vs non-digestive surgery) tended to be associated with the prevalence of SSI (coefficient 0.03, P = 0.064). CONCLUSION: The meta-analysis showed a low prevalence of SSI following day surgery, regardless of the surgical procedure.

[Treatment of thoracic anastomotic leaks after oesophagectomy with self-expanding and extractible covered stent]. / Traitement des fistules anastomotiques intrathoraciques apres esophagectomie par prothese couverte autoexpansive extractible.

We report a case of a thoracic anastomotic leak after oesophagectomy for cancer treated by surgical debridement, drainage and an endoscopically placed self-expanding stent. Intrathoracic, covered oesophageal stents appears to reduce leak-morbidity after oesophagectomy and may be considered as a cost-effective treatment alternative.

Cleft lip/palate and CDH1/E-cadherin mutations in families with hereditary diffuse gastric cancer.

We report the association of CDH1/E-cadherin mutations with cleft lip, with or without cleft palate (CLP), in two families with hereditary diffuse gastric cancer (HDGC). In each family, the CDH1 mutation was a splicing mutation generating aberrant transcripts with an in-frame deletion, removing the extracellular cadherin repeat domains involved in cell-cell adhesion. Such transcripts might encode mutant proteins with trans-dominant negative effects. We found that CDH1 is highly expressed at 4 and 5 weeks in the frontonasal prominence, and at 6 weeks in the lateral and medial nasal prominences of human embryos, and is therefore expressed during the critical stages of lip and palate development. These findings suggest that alteration of the E-cadherin pathway can contribute to human clefting.

[Ovarian dermoid cyst complicated by chemical peritonitis. Case report]. / Kyste dermoïde de l'ovaire compliqué d'une péritonite chimique. A propos d'un cas.

Dermoid cyst is the most frequent benign ovarian tumor. Its spontaneous or more frequently iatrogenic intraperitoneal rupture may lead to a chemical peritonitis. This is a rare complication but with a potentially dangerous issue. We report a case of a patient who developed chemical peritonitis after laparoscopic management of ovarian dermoid cysts. Three further interventions, associated with systemic anti-inflammatory treatment, were necessary to resolve symptoms completely. On the basis of this case, we aim to re-access the characteristics of dermoid cysts and highlight in particular the potential complication of chemical peritonitis and the following attitude to avoid this.

[Interest in agents for adhesion prevention after gynecologic surgery]. / Intérêt des produits antiadhérentiels en chirurgie gynécologique.

Adhesion barriers are intraperitoneal agents, solid or fluid, developed in order to prevent postoperative adhesions. In this article, we evaluate the efficiency of these new barrier agents for adhesion prevention in gynaecologic surgery, undertaking a review of controlled clinical trials published. Several human clinical trials demonstrated the safety and efficiency of both Interceed and Seprafilm. As far as other barrier agents are concerned, data are still insufficient to recommend them for clinical use. There is a need for other randomised controlled trials in order to evaluate functional efficiency of anti adhesion agents.

[Oesophageal squamous cell carcinoma stade III. State of surgery after radiochemotherapy (RCT)]. / Carcinomes malpighiens de l'oesophage de stade III, place de la chirurgie après chimioradiothérapie.

Neoadjuvant chemoradiotherapy is the gold standard of the treatment of advanced oesophageal squamous cell carcinoma. The role of surgery after chemoradiotherapy is still debated. Feasibility of curative resection depends on dose of radiotherapy, morbimortality rates, and nutrition status at the end of the protocol especially for non-responders patients. Adding surgery to radiochemotherapy improves local tumour control but does not increase overall survival of patients with advanced oesophageal squamous cell carcinoma. According to the two randomised trials published on the subject, surgery is not recommended after chemoradiotherapy for responders. Recommendations of French National Thesaurus are: exclusive chemoradiotherapy as reference, esophagectomy for residual tumour as alternative for operable patients. Surgery may be proposed for selected non-responders patients and some complete pathology response in expert center.

[Barrett's oesophagus: the rationale for surgical resection]. / Endobrachyoesophage: place de la résection.

Surgical resection has a limited place in the management of Barrett's oesophagus with high-grade dysplasia, except when failure of endoscopic mucosectomy is likely (extended Barrett's oesophagus, nodular or ulcerated lesions at endoscopy). For superficial carcinoma, it is often difficult to differentiate mucosal carcinoma (carrying a risk of nodal metastasis less than 7%) from submucosal carcinoma (carrying a risk of nodal metastasis ranging from 16 to 47%), oesophagectomy is routinely indicated if operative risk is low. When operative risk is not minimal, endoscopic mucosectomy is indicated for lesions limited to the mucosa and the proximal third of submucosa; for lesions extending beyond, an oesophagectomy must be discussed. These indications must take into account both age and general condition of the patient, as well as the expertise in oesophageal surgery of the group.

[Mesenteric panniculitis]. / Panniculite mésentérique.

Mesenteric panniculitis also named retractile mesenterite is a rare tumor-like lesion that thickens and shortens the mesentery. It is characterized by the association of inflammation, necrosis or fibrosis involving the adipose tissue of the bowel mesentery. The pathophysiology of this disease remains unclear despite associations with inflammatory diseases or malignancies, especially lymphomas that have been described. When symptomatic, patients may present with abdominal pain, palpable abdominal mass or intestinal obstruction. The disease remains asymptomatic in 30 to 50% of cases. Abdominal CT plays an important role in suggesting the diagnosis and can be useful in distinguishing the several conditions that can mimic mesenteric panniculitis. Nevertheless, pathologic examination of surgical excisional biopsies or sometimes percutaneous biopsies remains necessary to confirm the diagnosis and exclude an underlying infection or malignancy. Medical treatment may consist of therapy with anti inflammatory or immunosuppressive agents and can be proposed in highly symptomatic diseases. Surgical treatment should be exclusively attempted when intestinal obstruction or ischemia occur. Most of the time, it consists in intestinal derivation or segmental resection because complete excision of the lesions is often not possible. Mesenteric panniculitis usually has an uneventful clinical course and resolves spontaneously in a variable delay.

[Type I neurofibromatosis, pheochromocytoma and somatostatinoma of the ampulla. Literature review]. / Association neurofibromatose de type I, phéochromocytome et somatostatinome de l'ampoule de Vater. Revue de la littérature.

Gastrointestinal involvement in Von Recklinghausen's neurofibromatosis (autosomal dominant disease) is observed in 25% of patients and is frequently represented by duodenal carcinoids. We report a case of somatostatinoma of the ampulla in a 42-year-old female with neurofibromatosis and pheochromocytoma and show a literature review about the association of neurofibromatosis and somatostatinoma. This pathological association appears non hasardous and surgical ampullectomy offers a good alternative to pancreaticoduodenectomy in localised tumors treatment.

Overexpression of stromelysin-3, BM-40/SPARC, and MET genes in human esophageal carcinoma: implications for prognosis.

Molecular markers can improve staging and predict aggressive clinical behavior in esophageal cancer, thus helping to define appropriate therapeutic protocols and to identify patients who will benefit from surgery. We therefore characterized, by Northern blot and/or immunohistochemistry, the relative expression of three effectors involved in the invasion, angiogenesis, and dissemination of tumor cells in esophageal cancer versus nontumoral mucosae: (a) stromelysin-3 (ST3), a member of the metalloproteinase family; (b) basement membrane 40/secreted protein acidic and rich in cysteine (BM-40/SPARC), an extracellular matrix-associated protein involved in angiogenesis; and (c) the hepatocyte growth factor receptor MET, which triggers the scattering of epithelial cells. Results were analyzed in relation to clinicopathological parameters (cpTNE) including tumor size (T), lymph node status (N), periesophageal tissue invasion (E), disease recurrence, and overall survival. The ST3, BM-40/SPARC, and MET genes were found to be overexpressed in tumor samples compared to control mucosa. BM-40/SPARC and MET mRNA levels were not linked to any one of the cpTNE, indicating that this overexpression occurs at an early stage of neoplastic progression. In contrast, ST3 expression, identified by immunohistochemistry in fibroblastic cells surrounding neoplastic islets, correlated with tumor size and periesophageal tissue invasion. Of the 36 patients studied, those with high ST3 levels had shorter disease-free survival than those with low levels, but there was no relationship between the cpTNE and disease recurrence or survival. Our study demonstrates that ST3, BM-40/SPARC, and MET are involved in different steps of esophageal carcinogenesis and that ST3 overexpression is a marker of aggressive clinical behavior. We conclude that in esophageal cancer, ST3 might help to assess survival and the risk of recurrence after surgical resection.

[Cervical and upper-third thoracic oesophageal carcinoma: a single pathological entity?]. / Cancers de l'oesophage cervical et thoracique supérieur: une même entité pathologique ?

AIM OF THE STUDY: Cervical and upper-third thoracic oesophageal carcinomas are considered as a single pathological entity. The aim of this study was to compare postoperative and oncological results after surgical resection in these two locations. MATERIAL AND METHODS: Postoperative and oncological results were compared retrospectively in 155 patients who underwent surgery for carcinoma of the cervical (C group, n = 21) or upper-third thoracic (TS group, n = 134) oesophagus. RESULTS: The two groups were comparable regarding the pre-, peroperative and histological data. Postoperative mortality and morbidity rates in the C and TS groups were 4.8% and 10.4% (P= 0.413) and 57.1 and 50.7% (P= 0.585), respectively. R0 resection and recurrence rates were 61.9% and 73.1% (P= 0.289) and 50.0% and 51.1% (P= 0.941), respectively. Five-year survival rates were 0% and 35% in the overall population (P= 0.098) and 0 and 49% in the R0 population (P= 0.047), respectively. By multivariate analysis, cervical location of the tumour was found to be an independent factor of poor prognosis (relative risk= 3.1, 95% confidence interval= 1.3-7.8, P= 0.014). CONCLUSION: Prognosis after surgical resection of cervical oesophagus carcinoma is very poor. Surgery in this location should be proposed in case of chemoradiation failure.

[Severe blunt liver injury: reappraisal of criteria for nonoperative management decision. Experience with 88 cases]. / Traumatismes graves fermés du foie: à la recherche de critères décisionnels pour le choix du traitement non-opératoire. A propos d'une série de 88 cas.

AIM OF THE STUDY: To analyze the predictive value of computed tomography (CT) and initial physiologic and laboratory data findings in the immediate operative (OP) or non-operative (NOP) management of blunt liver injury (BL). METHODS: Eighty-eight BL, grade III (51), grade IV (28) and nine grade V (9), aged 26.2 years (16-75) were identified. Hemoperitoneum on CT, hemodynamic status, physiologic and laboratory data <24 hours or preoperative (transfusion, vascular filling) and follow-up >48 hours were analyzed. RESULTS: Data of 71/88 (80%) NOP and 17/88 (20%) OP patients were reviewed. A secondary laparotomy or laparoscopy was necessary in 11/71 TNO. Six OP (35%) and 1 NOP patients died. Blood units transfused were 1.33 (0-10) vs 5.9 (0-22) and vascular filling 1.45 (0.5-5.5) vs 3.6L (2-12) (P<10(-6), P<4.10(-3) respectively). NOP patients had less severe hemoperitoneum (31 vs 94%, P<10(-5)) and hemodynamic instability (8.5 vs 94%, P<10(-4)). But, there was an overlap of values of blood units transfused, amount of vascular filling and initial haemoglobin levels between NOP and OP patients and among CT grades of liver injury. No cut-off values could be determined: 33% NOP received >4 blood units and >3 L vascular filling; 30% had severe hemoperitoneum. In OP group 23.5% patients had lower values and no severe hemoperitoneum. CONCLUSION: In the management of BL, vascular filling and blood transfusion increased with the grade of CT liver injury and were globally more elevated in the operative group but did not individually correlate with hemodynamic stability and did not authorize, by themselves, to decide between operative versus non-operative management.

[Complications following oesophagectomy: mechanism, detection, treatment and prevention]. / Complications après oesophagectomie: mécanisme, détection, traitement et prévention.

Oesophageal surgery remains a relatively morbid operation with potentially devastating complications that can be minimized by prevention, early recognition, and appropriate management. Anastomotic leak, conduit necrosis, and pulmonary failure are the most serious complications. The management of complications following oesophagectomy is reviewed in the following section.

Surgical management of carcinoma of the hypopharynx and cervical esophagus: analysis of 209 cases.

BACKGROUND: Free jejunal transfer has become the standard technique for reconstruction of the pharynx and hypopharynx, especially with proximal neoplastic lesions, whereas gastric tube interposition is the technique of choice for reconstruction of the hypopharynx and cervical esophagus when resection extends below the thoracic inlet. HYPOTHESIS: Surgical ablation is a viable option for advanced hypopharyngeal and cervical esophageal neoplasms, with stomach interposition a safe and preferred method of reconstruction. DESIGN: Retrospective analysis. SETTING: University hospital that is a regional referral institution for esophageal cancer treatment and complex digestive reconstructions after esophagectomy. PATIENTS: We reviewed the records of 209 patients who underwent total pharyngolaryngectomy between May 1982 and July 1999. The majority of patients had advanced cancer: hypopharyngeal in 131 cases and cervical esophageal in 78 cases. INTERVENTIONS: Pharyngolaryngectomy and total esophagectomy with pharyngogastric anastomoses (n = 127); pharyngolaryngectomy, cervical esophagectomy, and reconstruction with free jejunal transplant (n = 77); and pharyngolaryngectomy and total esophagectomy with pharyngocolic anastomoses (n = 5). MAIN OUTCOME MEASURES: Postoperative mortality and morbidity, long-term survival, and prognostic factors influencing survival. RESULTS: The postoperative in-hospital mortality rate was 4.8% (10 patients), with a postoperative morbidity rate of 38.3%. Alimentary continuity was achieved using the stomach (127 patients), colon (5 patients), or free jejunal autograft (77 patients). The 1-year and 5-year survival rates were 62% and 24%, respectively. There was no significant difference with regard to the survival between gastric transposition and free jejunal autograft, but there were fewer complications in the gastric pull-up group (33% vs 47%, P<.05). The significant adverse factors affecting survival were tumor cervical localization, postoperative complications, disease stages pT3 and pT4 for the cervical esophageal tumors, microscopic pharyngeal penetration, or incomplete resection. The significant beneficial factors were tumor hypopharyngeal localization and postoperative radiotherapy. CONCLUSIONS: Surgical ablation is a viable option for advanced hypopharyngeal and cervical esophageal neoplasms, with stomach interposition the preferred method of reconstruction. Although the prognosis is poor, satisfactory short-term palliation can be achieved. The significant adverse factors affecting survival should be taken into account to select the candidates for surgery.

Surgery after induction chemoradiotherapy for oesophageal cancer.

AIM: We discuss the role of surgery after induction chemoradiotherapy, when a complete response is apparent. METHODS: We enrolled 247 consecutive patients who underwent chemoradiotherapy and oesophagectomy for cancer. Patients were classified in two groups as to whether they had chemoradiotherapy (n = 60) or not (n = 187) before surgery. RESULTS: The 5-year survival rate of patients with complete response was 54% and was significantly higher than that of the other group (P = 0.018). Of the 60 patients responding, 34 (56.7%) were found to have a complete pathological tumour response (pT0). The overall sensitivity and specificity of the post-chemoradiotherapy restaging were 60.7% and 86.4%. CONCLUSIONS: Complete response after induction chemoradiotherapy is not a reliable tool in the management of oesophageal cancer. We need to improve postchemoradiotherapy restaging to be sure that chemoradiotherapy will provide the same long-term survival rates as surgery.
