Evaluation of diagnostic laparoscopy for penetrating abdominal injuries: About 131 anterior abdominal stab wound.

BACKGROUND: The management of hemodynamically stable patients with anterior abdominal stab wounds (AASW) is debated. Mini-invasive techniques using laparoscopy and non-operative management (NOM) have reduced the rate of nontherapeutic laparotomies after AASW leading to unnecessary morbidity. The aim of this study was to determine with a systematic diagnostic laparoscopy of peritoneal penetration (PP), patients who do not require abdominal exploration in the management of stable patient with an AASW. METHODS: All patients with AASW were retrospectively recorded from 2006 to 2018. Criteria of inclusion were AASW patients who underwent a systematic diagnostic laparoscopy. Criteria of exclusion were patients with an evisceration, impaling, clinical peritonitis, and hemodynamic instability. If no PP was detected, laparoscopy was terminated. If defects of peritoneum were found, a laparotomy was performed looking for diagnosis and treatment of intra-abdominal injuries. RESULTS: On 131 AASW patients, 35 underwent immediate emergency laparotomy, 96 underwent diagnostic laparoscopy, 47 were positive (PP) and had an intra-abdominal exploration by laparotomy, 32 (68.1%) had intra-abdominal injuries which required treatment. All patients with an intra-abdominal injury had a positive diagnostic laparoscopy. For the 49 patients with a negative laparoscopy, the mean hospital stay was 1.6 days with ambulatory care for some patients. No patient presented a delayed injury. Non-therapeutic laparotomy rate was 15.6%. For patients who did not have an intra-abdominal injury the morbidity rate was low (3%). CONCLUSION: Our study shows that diagnostic laparoscopy was safe, with a low duration of hospitalization, a possible ambulatory care and had an excellent ability to screen the patients who did not need a abdominal exploration. This management can avoid many unnecessary laparotomies with an acceptable rate of negative laparotomy, without any delayed diagnosis of intra-abdominal injuries and with a low morbidity rate.

[Bariatric surgical procedures]. / Les techniques chirurgicales bariatriques.

Obesity physioptahology is complex and involves several factors (genetic, behavioral, psychological…). In this still undefined context, bariatric surgery modifies gastrointestinal tract anatomy, reduces the caloric intake and modifies gastrointestinal hormonal secretions for some of them. Aim of this work was to describe bariatric surgical procedures (sleeve, gastric band, short-gastric gastric, biliopancreatic diversion), specifying their historical context and considering possible evolutions.

Is perineural invasion more accurate than other factors to predict early recurrence after pancreatoduodenectomy for pancreatic head adenocarcinoma?

BACKGROUND: Some patients operated by pancreaticoduodenectomy for resectable pancreatic head adenocarcinoma will present with a recurrence during the first year (early recurrence). OBJECTIVE: The aim of this study was to determine prognostic factors associated with early recurrence in a large retrospective study. METHODS: From January 1995 to November 2010, all patients operated by pancreaticoduodenectomy for pancreatic head adenocarcinoma in our institution were retrospectively included. Univariate and multivariate analyses were performed to determine factors associated with early recurrence. RESULTS: A total of 166 patients were included; 57 patients (34%) developed early recurrence. In univariate analysis, factors associated with early recurrence were perineural invasion (p = 0.0002), preoperative bilirubin (p = 0.01), lymph node ratio (LNR) ≥0.2 (p = 0.009), and T stage (p = 0.02). In multivariate analysis, perineural invasion (odds ratio [OR] 3.31; 95% confidence interval [CI] 1.42-7.72; p = 0.005), LNR ≥0.2 (OR 2.55; 95% CI 1.17-5.52; p = 0.02), and preoperative bilirubin (OR 1.04; 95% CI 1.01-1.07; p = 0.03) were independent factors associated with early recurrence. Perineural invasion was also associated with poor overall survival (p = 0.001) and poor disease-free survival (p = 0.07). CONCLUSION: In our study, perineural invasion (OR 3.31) is more accurate than T stage and lymph node status (OR 2.55) to predict early recurrence after pancreatoduodenectomy for pancreatic head adenocarcinoma.

Totally endoscopic lateral parathyroidectomy: prospective evaluation of 200 patients. ESES 2010 Vienna presentation.

PURPOSE: Several new minimally invasive techniques (mini-open, video-assisted, and endoscopic procedures) for parathyroidectomy have been described. However, totally endoscopic lateral approach parathyroidectomy (Henry technique) is not routinely performed. METHODS: This is a prospective study of 200 consecutive patients that underwent totally endoscopic lateral parathyroidectomy. RESULTS: Two hundred of 387 patients (52%) with primary hyperparathyroidism were included. Fifty-six patients (28%) were converted to open parathyroidectomy. Causes for conversion were lack of intraoperative localization (11%), difficult dissection (10%), bleeding (4%), failure of normalization of IOPTH results (2%), and other causes (1%). Gland localization (areas 1 to 2 versus area 3) and CaPTHus score (<3 versus ≥3) were not associated with the risk of conversion. Mean postoperative follow-up was 13 months, and 196 patients (98%) were cured. CONCLUSIONS: Totally endoscopic lateral approach can be proposed in more than half of the patients with good immediate results. Conversion rate remains important and may explain low acceptance rate of this technique.
