Factors That Affect Efficacy of Ultrasound Surveillance for Early Stage Hepatocellular Carcinoma in Patients With Cirrhosis

BACKGROUND & AIMSnUltrasound surveillance does not detect early stage hepatocellular carcinomas (HCCs) in some patients with cirrhosis, although the reasons for this have not been well studied. We assessed the rate at which ultrasound fails to detect early stage HCCs and factors that affect its performance.nnnMETHODSnWe collected information on 1170 consecutive patients included in the Italian Liver Cancer (ITA.LI.CA) database who had Child-Pugh A or B cirrhosis and were diagnosed with HCC during semiannual or annual ultrasound surveillance, from January 1987 through December 2008. Etiologies included hepatitis C virus infection (59.3%), alcohol abuse (11.3%), hepatitis B virus infection (9%), a combination of factors (15.6%), and other factors (4.7%). Surveillance was considered to be a failure when patients were diagnosed with HCC at a stage beyond the Milan criteria (1 nodule ≤5 cm or ≤3 nodules each ≤3 cm).nnnRESULTSnHCC was found beyond Milan criteria in 34.3% of surveilled patients (32.2% during semi-annual surveillance and 41.3% during annual surveillance; P < .01). Nearly half of surveillance failures were associated with at least one indicator of aggressive HCC (levels of AFP >1000 ng/mL, infiltrating tumors, or vascular invasion and metastases). Semiannual surveillance, female sex, Child-Pugh class A, and α-fetoprotein levels of 200 ng/mL or less were associated independently with successful ultrasound screening for HCC.nnnCONCLUSIONSnBased on our analysis of surveillance for HCC in patients with cirrhosis, the efficacy of ultrasound-based screening is acceptable. Ultrasound was least effective in identifying aggressive HCC, and at surveillance intervals of more than 6 months.

Acute colonic obstruction : endoscopic stenting and laparoscopic resection

IntroductionAcute colonic obstruction is a frequent emergency condition in a general surgical setting. The use of an endoscopic self-expanding stent can relieve obstruction and eventually prepare the patient for elective laparoscopic or open surgery.Materials and MethodsFrom September 2001 to March 2006 we treated 25 patients with acute left or transverse colonic obstruction. In 23 patients stents were positioned planning an elective procedure to be performed. In two patients with multiple liver metastases and malignant ascites only a palliation was intended (2 of 25 patients).ResultsMean age was 66.6 years. The 23 patients who underwent resection, 14 females and nine males, had a mean age of 65.5 years. Obstructions were located in the rectum (five), in the sigmoid (16) and in the transverse colon (two). In one patient stricture was due to radiotherapy, in twenty four cases it was due to primary cancer. Stents were successfully placed in 24 patients. In one of them two stents had to be placed due to the slippage of the first one beyond the stricture. Excellent resumption of colonic transit was achieved in all the patients. No complications were observed. In 23 patients resection was performed (19 laparoscopy; four open). Complications occurred in one patient in open group (pancreatic fistula after splenectomy) and was treated conservatively. Mean postoperative stay was 18.5 (range 9–35) days for the open group and 12 (range 9–20) for the laparoscopic group. Mean follow-up was 36 months.Conclusionsuse of self expanding endoscopic colonic stents can provide excellent palliation in acute obstruction, aiming both to prepare the colon to elective surgery after adequate preparation or to palliate the stricture in case of unresectable advanced tumors.

Laparoscopic re-sleeve gastrectomy as a treatment of weight regain after sleeve gastrectomy.

AIMnTo evaluate laparoscopic re-sleeve gastrectomy as a treatment of weight regain after Sleeve.nnnMETHODSnLaparoscopic sleeve gastrectomy is a common bariatric procedure. Weight regain after long-term follow-up is reported. Patients were considered for laparoscopic re-sleeve gastrectomy when we observed progressive weight regain and persistence of comorbidities associated with evidence of dilated gastric fundus and/or antrum on upper gastro-intestinal series. Follow-up visits were scheduled at 1, 3, 6 and 12 mo after surgery and every 6 mo thereafter. Measures of change from baseline at different times were analyzed with the paired samples t test.nnnRESULTSnWe observed progressive weight regain after sleeve in 11 of the 201 patients (5.4%) who had a mean follow-up of 21.1 ± 9.7 mo (range 6-57 mo). Three patients started to regain weight after 6 mo following Sleeve, 5 patients after 12 mo, 3 patients after 18 m. Re-sleeve gastrectomy was always performed by laparoscopy. The mean time of intervention was 55.8 ± 29.1 min. In all cases, neither intra-operative nor post-operative complications occurred. After 1 year follow-up we observed a significant (P < 0.05) mean body mass index reduction (-6.6 ± 2.7 kg/m(2)) and mean % excess weight loss (%EWL) increase (+31.0% ± 15.8%). An important reduction of antihypertensive drugs and hypoglycemic agents was observed after re-sleeve in those patients affected by hypertension and diabetes. Joint problems and sleep apnea syndrome improved in all 11 patients.nnnCONCLUSIONnLaparoscopic re-sleeve gastrectomy is a feasible and effective intervention to correct weight regain after sleeve.

Sports hernia and femoroacetabular impingement in athletes: A systematic review

AIMnTo investigate the association between sports hernias and femoroacetabular impingement (FAI) in athletes.nnnMETHODSnPubMed, MEDLINE, CINAHL, Embase, Cochrane Controlled Trials Register, and Google Scholar databases were electronically searched for articles relating to sports hernia, athletic pubalgia, groin pain, long-standing adductor-related groin pain, Gilmore groin, adductor pain syndrome, and FAI. The initial search identified 196 studies, of which only articles reporting on the association of sports hernia and FAI or laparoscopic treatment of sports hernia were selected for systematic review. Finally, 24 studies were reviewed to evaluate the prevalence of FAI in cases of sports hernia and examine treatment outcomes and evidence for a common underlying pathogenic mechanism.nnnRESULTSnFAI has been reported in as few as 12% to as high as 94% of patients with sports hernias, athletic pubalgia or adductor-related groin pain. Cam-type impingement is proposed to lead to increased symphyseal motion with overload on the surrounding extra-articular structures and muscle, which can result in the development of sports hernia and athletic pubalgia. Laparoscopic repair of sports hernias, via either the transabdominal preperitoneal or extraperitoneal approach, has a high success rate and earlier recovery of full sports activity compared to open surgery or conservative treatment. For patients with FAI and sports hernia, the surgical management of both pathologies is more effective than sports pubalgia treatment or hip arthroscopy alone (89% vs 33% of cases). As sports hernias and FAI are typically treated by general and orthopedic surgeons, respectively, a multidisciplinary approach for diagnosis and treatment is recommended for optimal treatment of patients with these injuries.nnnCONCLUSIONnThe restriction in range of motion due to FAI likely contributes to sports hernias; therefore, surgical treatment of both pathologies represents an optimal therapy.

Proximal Leakage After Laparoscopic Sleeve Gastrectomy: an Analysis of Preoperative and Operative Predictors on 1738 Consecutive Procedures

BackgroundThe purpose of this paper was to search for predictive factors for proximal leakage after laparoscopic sleeve gastrectomy (LSG) in a large cohort from a single referral center.Materials and MethodsOne thousand seven hundred and thirty-eight patients, collected in a prospectively held database from 2008 to 2016, were retrospectively analyzed. The correlation between postoperative leakage and both preoperative (age, gender, height, weight, BMI, and obesity-related morbidities) and operative variables (the distance from pylorus at which the gastric section was started, operative time, experience of surgeons who performed the LSG, and the surgical materials used) was analyzed. The experience of the surgeons was calculated in the number of LSGs performed. The surgical materials considered were stapler, cartridges, and reinforcement of the suture.ResultsProximal leakage was observed in 45 patients out of 1738 (2.6%). No correlation was found between leakage and the preoperative variables analyzed. The operative variables that were found to be associated with lower incidence of leakage at the multivariate analysis (pxa0<xa00.05) were the reinforcement of the staple line (or overriding suture or buttressing materials) and the experience of the surgeons. A distance of less than 2xa0cm from the pylorus resulted to be significantly related to a higher incidence of fistula at the univariate analysis.ConclusionsIn this large consecutive cohort study of LSG, proximal staple line reinforcement (buttress material or suture) reduced the risk of a leak. The risk of a proximal leak was much higher in the surgeons first 100 cases, which has implications for training and supervision during this “learning curve” period.

Titanium versus absorbable tacks comparative study (TACS): a multicenter, non-inferiority prospective evaluation during laparoscopic repair of ventral and incisional hernia: study protocol for randomized controlled trial

BackgroundLaparoscopic repair of ventral and incisional hernias has gained popularity since many studies have reported encouraging results in terms of outcomee and recurrence. Choice of mesh and fixation methods are considered crucial issues in preventing recurrences and complications. Lightweight meshes are considered the first choice due to their biomechanical properties and the ability to integrate into the abdominal wall. Titanium helicoidal tacks still represent the “gold standard” for mesh fixation, even if they have been suggested to be involved in the genesis of post-operative pain and complications. Recently, absorbable tacks have been introduced, under the hypothesis that there will be no need to maintain a permanent fixation device after mesh integration. Nevertheless, there is no evidence that absorbable tacks may guarantee the same results as titanium tacks in terms of strength of fixation and recurrence rates. The primary end point of the present trial is to test the hypothesis that absorbable tacks are non-inferior to titanium tacks in laparoscopic incisional and ventral hernia repair (LIVHR) by lightweight polypropylene mesh, in terms of recurrence rates at 3-year follow-up. Surgical complications, post-operative stay, comfort and pain are secondary end points to be assessed.Methods/DesignTwo hundred and twenty patients with ventral hernia will be randomized into 2 groups:Group A (110) patients will be submitted to LIVHR by lightweight polypropylene mesh fixed by titanium tacks;Group B (110) patients will be submitted to LIVHR by lightweight polypropylene mesh fixed by absorbable tacks.DiscussionA few retrospective studies have reported similar results when comparing absorbable versus non-absorbable tacks in terms of intraoperative and early post-operative outcomes. These studies have the pitfalls to be retrospective evaluation of small series of patients, and the reported results still need to be validated by larger series and prospective studies.The aim of the present trial is to investigate and test the non-inferiority of absorbable versus non-absorbable tacks in terms of hernia recurrence rates, in order to assess whether the use of absorbable tacks may achieve the same results as non-absorbable tacks in mid-term and long-term settings.Trial registration numberNCT02076984: 5 June 2014 (ClinicalTrials.gov)

Laparoscopic sleeve gastrectomy combined with Rossetti fundoplication (R-Sleeve) for treatment of morbid obesity and gastroesophageal reflux

BACKGROUNDnGastroesophageal reflux (GERD) can be considered an obesity-related disease. Roux-en-Y gastric bypass is considered the gold standard for its therapeutic effects on acid reflux.nnnOBJECTIVESnThe aim of this retrospective study is to assess the effectiveness of combined laparoscopic sleeve gastrectomy and Rossetti antireflux fundoplication for the treatment of morbidly obese patients with GERD.nnnSETTINGnA private academic hospital in Italy.nnnMETHODSnForty obese patients with GERD underwent laparoscopic sleeve gastrectomy-Rossetti laparoscopic fundoplication from January 1 to October 31, 2015. A specific informed consent was obtained. Minimum follow-up was 12 months. No cases were lost to follow-up.nnnRESULTSnMean body mass index was 44.4 ± 4.7 kg/m2; all patients had GERD. Mean operative time was 38 ± 6 minutes. The mortality rate was 0%. No intraoperative or medium- or long-term complications were reported. Excess weight loss percent at 1, 3, 6, 12 months was 25.6 ± 6.1, 41.9 ± 12.5, 56.7 ± 13.0, 61.7 ± 13.6, respectively. Excess body mass index loss percent at 1, 3, 6, 12 months was 29.3 ± 3.4, 47.2 ± 5.2, 64.0 ± 8.6, 73.3 ± 9.9, respectively. At the 12-month follow-up visit, 95% of the patients reported a good sense of repletion without episodes of vomiting, nausea, or dysphagia.nnnCONCLUSIONSnRossetti laparoscopic fundoplication is well tolerated, feasible, and safe in obese patients with GERD, with good postoperative weight results. Following this evidence, 2 monocentric prospective and randomized studies will start to analyze and confirm the reported data.
