Prospective randomized study comparing quality of life after shoudice or mesh plug repair for inguinal hernia: short-term results

Postoperative pain is a major obstacle in hernia repair surgery, and the choice of clinically efficacious surgical technique should also result in the least postoperative pain and patients\u27 quality of life (QoL). The aim of this prospective randomized study was to compare two surgical techniques for open inguinal hernia repair by assessing the patients\u27 QoL. Men (18-to-75 years old) with primary unilateral inguinal hernia underwent Mesh Plug (MP; n = 156; Bard (PerFix Plug, CR Bard Inc, Murray Hill, NJ) and Shouldice (S; n = 144) techniques. We evaluated: 1) Intensity of postoperative pain (visual analog scale [VAS]) and 2) quality of life (QoL; Medical Outcomes Study Short-Form 36 [SF-36]). Patients undergoing MP had significantly lower VAS scores on postoperative days (POD) 1 (22.1 vs 27.4, p =.003) and 2 (13.2 vs 21.4, p <.0001) compared to those in the S group. The QoL was also improved in patients undergoing MP on PODs 8 and 45. Total duration of operation, length of hospital stay, and cessation of normal activities were significantly shorter in the MP group. Compared to the S technique, the MP technique results in significantly less postoperative pain and improved QoL

Isolated Splenic Metastasis from Colorectal Cancer: Report of a Case

The authors report a case of a patient with splenic metastasis with previous history of colorectal cancer. A 69-year-old woman underwent a left hemicolectomy for sigmoid colon cancer. The tumor was staged T3N0M0. Two years after the operation, there was an elevation of CEA and computed tomography (CT) scan revealed a mass in the spleen, considered as an isolated metastasis. The patient underwent splenectomy. Histological diagnosis confirmed a metastatic adenocarcinoma from colorectal carcinoma. Patient was alive without neoplasic recurrence 5 years after splenectomy. Generally, splenic metastasis is uncommon. However, with the case of colorectal cancers, metastasis to the spleen is particularly rare. As with splenic metastasis of all primary tumors, the literature recommends that the treatment, where possible, is surgical

Prognostic factors in node-negative colorectal cancer: a retrospective study from a prospective database

PURPOSE: There is a need to identify a subgroup of high-risk patients with node-negative colorectal cancer who have a poor long-term prognosis and may benefit from adjuvant therapies. The aim of this study was to evaluate the prognostic impact of clinical and pathological parameters in a retrospective study from a prospective, continuous database of homogenously treated patients. METHODS: This study included 362 patients operated in a single institution for Dukes A and B (node-negative) colorectal cancer. The median follow-up was 140 months. The prognostic value of 13 clinical and pathological parameters was investigated. RESULTS: Multivariate analysis identified six independent prognostic factors: age at time of diagnosis (hazard ratio (HR) = 1.076), number of lymph nodes removed (HR = 0.948), perineural invasion (HR = 2.173), venous invasion (HR = 1.959), lymphatic vessel invasion (HR = 2.126), and T4 stage (HR = 5.876). CONCLUSION: These parameters could be useful in identifying patients with high-risk node-negative colorectal cancer who should be presented to adjuvant therapy

Effect of preoperative endoscopic biliary drainage on infectious morbidity after pancreatoduodenectomy: a case-control study

BackgroundThe utility of preoperative endoscopic biliary drainage (PEBD) in jaundiced patients before pancreatoduodenectomy (PD) is still debated. This is in part due to the heterogeneity of the studied population, including different tumor location, drainage techniques, and surgical procedures. The aim of the current study was to report the influence of PEBD on postoperative infectious morbidity of PD. Materials and Methods Between January 1996 and December 2004, 124 patients underwent a PD and 28. Twenty-eight (22.6%) of these patients underwent a PEBD. This group of patients was matched to 28 control patients who underwent PD without PEBD during the same period. The 2 groups were matched for age, sex, indication of surgery, and serum bilirubin levels. Results The specific morbidity of PEBD before surgery was 10.7% (n = 3). The postoperative overall morbidity, medical morbidity, and surgical morbidity rates were not different between the 2 groups. At the time of surgery, 89.3% (n = 25) of the patients in the PEBD group had positive bile culture in comparison to 19.4% (n = 4) in the control group (P < .001). The number of patients with 1 or more infectious complications was higher in the PEBD group (50%; n = 14) than in the control group (21.4%; n = 6) (P = .05). Conclusions Before PD, PEBD should be routinely avoided whenever possible in patients with potentially resectable pancreatic and peripancreatic lesions. In patients with cholangitis, requiring extensive preoperative assessment (such as liver biopsy) or neoadjuvant treatment, PEBD might still be indicated

Should pancreaticoduodenectomy be performed in the elderly?

BACKGROUND/AIMS: Pancreaticoduodenectomy (PD) is indicated in benign or malignant pancreatic head diseases. It is a difficult operation with high morbidity especially in elderly patients. The aim of our study was to determine whether pancreaticoduodenectomy is associated with higher morbidity and mortality in patients ≥ 70 years old. METHODOLOGY: During 17 years, 173 patients were operated by Whipple intervention, whatever the disease. From a prospective database, patients were divided in 2 groups (Group A ≥ 70 years old, Group B <70). RESULTS: Postoperative mortality was not significantly higher in elderly (12% vs. 4.1%; p=0.06). However, re-intervention and morbidity were more important in univariate analysis (p=0.03 and p=0.002 respectively). In multivariate analysis, age ≥ 70 years old was not an independent prognostic factor of mortality (p=0.27) and re-intervention (p=0.07). Whereas age (p=0.04) and preoperative morbidity (p=0.02) were independent prognostic factors of morbidity. CONCLUSIONS: PD requires careful patient selection. However, age should not be a limiting factor

Surgical treatment of large incisional hernias by intraperitoneal insertion of Parietex® composite mesh with an associated aponeurotic graft (280 cases)

AIMS OF THE STUDY: To evaluate post-operative complications and the recurrence rate after repair of large ventral incisional hernia with an open technique using intraperitoneal composite mesh and an associated aponeurotic overlay. PATIENTS AND METHODS: This prospective study included a total of 280 patients who underwent repair of large incisional hernia using Parietex(®) composite mesh. RESULTS: The post-operative mortality rate was 0.35%. Six patients (2%) developed subcutaneous surgical site infection without infection of the prosthesis. Six other patients (2%) developed a deep-seated infection; in three cases, the mesh had to be removed. Nine patients (3.2%) developed recurrent incisional hernia. CONCLUSION: Large ventral incisional hernias can be effectively treated by the intraperitoneal placement of Parietex(®) composite mesh overlaid by an aponeurotic graft; the incidence of complications in this prospective study was very low

L’Echinococcus granulosus, parasite appartenant à la famille des Cestodes est responsable, à travers sa forme larvaire, d’une maladie : l’hydatidose. Celle-ci se manifeste typiquement au niveau hépatique ou pulmonaire ; cependant une fois sur dix, l’embryon va se loger dans n’importe quel tissu ou organe du corps humain. Les auteurs rapportent quatre cas de localisation inhabituelle de l’hydatidose : rénale, musculaire, pancréatique et thyroïdienne

Standardized Laparoscopic Intracorporeal Right Colectomy for Cancer: Short-Term Outcome in 111 Unselected Patients

Purpose This study was designed to evaluate the impact of a standardized laparoscopic intracorporeal right colectomy on the short-term outcome of patients with neoplasia. Methods Consecutive patients with histologically proven right colon neoplasia underwent a standardized laparoscopic intracorporeal right colectomy with medial to lateral approach encompassing ten sequential steps: 1) ligation of ileocolic vessels, 2) identification of right ureter, 3) dissection along superior mesenteric vein, 4) division of omentum, 5) division of right branch of middle colic vessels, 6) transection of transverse colon, 7) mobilization of right colon, 8) transection of terminal ileum, 9) ileocolic anastomosis, 10) delivery of specimen. Values were medians (ranges). Results From July 2002 to June 2005, 111 laparoscopic intracorporeal right colectomies were attempted with a 5.4 percent conversion rate. There were 57 women and 54 men, aged 64.9 (range, 40–85) years, with body mass index of 33 (range, 20–43), American Society of Anesthesiology score of 2 (range, 2–4), 36.9 percent comorbidities, and 37.8 percent previous abdominal surgery. The indication for surgery was cancer in 109 patients. Operative time was 120 (range, 80–185) minutes. Estimated blood loss was 69 (range, 50–600) ml. Overall length of skin incisions was 66 (range, 60–66) mm; 29 (range, 2–41) lymph nodes were harvested. Length of stay was four (range, 2–30) days. Complication rate was 4.5 percent. Conclusions A standardized laparoscopic intracorporeal right colectomy resulted in a favorable short-term outcome in unselected patients with neoplasia of the right colon

Caged Gammarus fossarum (crustacea) as a robust tool for the characterization of bioavailable contamination levels in continental waters. Toward the determination of threshold values

We investigated the suitability of an active biomonitoring approach, using the ecologically relevant species Gammarus fossarum, to assess trends of bioavailable contamination in continental waters. Gammarids were translocated into cages at 27 sites, in the Rhône-Alpes region (France) during early autumn 2009. Study sites were chosen to represent different physico-chemical characteristics and various anthropic pressures. Biotic factors such as sex, weight and food availability were controlled in order to provide robust and comparable results. After one week of exposure, concentrations of 11 metals/metalloids (Cd, Pb, Hg, Ni, Zn, Cr, Co, Cu, As, Se and Ag) and 38 hydrophobic organic substances including polycyclic aromatic hydrocarbons (PAHs), polychlorobiphenyles (PCBs), pentabromodiphenylethers (PBDEs) and organochlorine pesticides, were measured in gammarids. All metals except Ag, and 33 organic substances among 38 were quantified in G. fossarum, showing that this species is relevant for chemical biomonitoring. The control of biotic factors allowed a robust and direct inter-site comparison of the bioavailable contamination levels. Overall, our results show the interest and robustness of the proposed methodological approach for assessing trends of bioavailable contamination, notably for metals and hydrophobic organic contaminants, in continental waters. Furthermore, we built threshold values of bioavailable contamination in gammarids, above which measured concentrations are expected to reveal a bioavailable contamination at the sampling site. Two ways to define such values were investigated, a statistical approach and a model fit. Threshold values were determined for almost all the substances investigated in this study and similar values were generally derived from the two approaches. Then, levels of contaminants measured in G. fossarum at the 27 study were compared to the threshold values obtained using the model fit. These threshold values could serve as a basis for further implementation of quality grids to rank sites according to the extent of the bioavailable contamination, with regard to the applied methodology

Complications after pancreatic resection: diagnosis, prevention and management

BACKGROUND: Although mortality after pancreaticoduodenectomy (PD) or distal pancreatectomy (DP) has decreased, morbidity still remains high. The aim of this review article is to present, define, predict, prevent, and manage the main complications after pancreatic resection (PR). METHODS: A non-systematic literature search on morbidity and mortality after PR was undertaken using the PubMed/MEDLINE and Embase databases. RESULTS: The main complications after PR are delayed gastric emptying (DGE), pancreatic fistula (PF), and bleeding, as defined by the International Study Group on Pancreatic Surgery. PF occurs in 10% to 15% of patients after PD and in 10% to 30% of patients after DP. The different techniques of pancreatic anastomosis and pancreatic remnant closure do not show significant advantages in the prevention of PF, nor does the perioperative use of somatostatin and its analogues. The trend is for conservative or interventional radiology therapy for PF (with enteral nutrition), which achieves a success rate of approximately 80%. DGE after PD occurs in 20% to 50% of patients. Prophylactic erythromycin may reduce the incidence of DGE. Gastric aspiration with erythromycin is usually effective in one to three weeks. Bleeding (gastrointestinal and intraabdominal) occurs in 4% to 16% of patients after PD and in 2% to 3% of patients after DP. Endovascular treatment can only be used for a haemodynamically stable patient. In cases of haemodynamic instability or associated septic complications, surgical treatment is necessary. In expert centres, the mortality rates can be less than 1% after DP and less than 3% after PD. CONCLUSION: There is a need for improved strategies to prevent and treat complications after PR
