Gastrectomy with lymph node dissection is the cornerstone of curative treatment of gastric cancer. Extent of lymphadenectomy may differ depending on T-stage, as the rate of lymph node metastases may differ. The objective of this systematic review is to investigate and compare the prevalence of nodal metastases in the individual lymph node stations between different T-stages.Data reporting and structure of this systematic review follows the PRISMA checklist. The Medline and PubMed databases were systematically searched. The search included the following Mesh terms: "Stomach Neoplasms", "Lymphatic Metastasis" and "Lymph Node Excision". The primary outcome was the highest prevalence of nodal metastases per T-stage.The initial search resulted in 175 eligible articles. Five articles met the inclusion criteria and were accordingly analyzed. Concerning the lymph node stations 1 to 7, the lymph nodes along the lesser gastric curvature (station 3) show the highest metastases rate (T1: 5.5%, T2: 21.9%, T3: 41.9%, T4: 71.0%). Concerning the lymph node stations 8 to 20, the lymph nodes around the common hepatic artery (station 8) show the highest metastases rate (T1: 0.8%, T2: 7.9%, T3: 14.0%, T4: 28.2%).An overall low prevalence of nodal metastases in the individual lymph node stations in early, T1 gastric carcinomas and an overall high prevalence in more advanced, T3 and T4 gastric carcinomas endorse a more tailored approach based on the different gastric T-stages. In addition, a less extensive lymphadenectomy seems justified in early T1 carcinoma.This systematic review provides an overview of the prevalence of nodal metastases for the individual lymph node stations between different T-stages, showing an overall low prevalence in early, T1 gastric carcinomas and an overall high prevalence in the more advanced, T3 and T4 gastric carcinomas.

Background Stoma reversal is often considered a straightforward procedure with low short-term complication rates. The aim of this study was to determine the rate of incisional hernia following stoma reversal and identify risk factors for its development. Methods This was an observational study of consecutive patients who underwent stoma reversal between 2009 and 2015 at a teaching hospital. Patients followed for at least 12 months were eligible. The primary outcome was the development of incisional hernia at the previous stoma site. Independent risk factors were assessed using multivariable logistic regression analysis. Results After a median follow-up of 24 (range 12-89) months, 110 of 318 included patients (34·6 per cent) developed an incisional hernia at the previous stoma site. In 85 (77·3 per cent) the hernia was symptomatic, and 72 patients (65·5 per cent) underwent surgical correction. Higher BMI (odds ratio (OR) 1·12, 95 per cent c.i. 1·04 to 1·21), stoma prolapse (OR 3·27, 1·04 to 10·27), parastomal hernia (OR 5·08, 1·30 to 19·85) and hypertension (OR 2·52, 1·14 to 5·54) were identified as independent risk factors for the development of incisional hernia at the previous stoma site. In addition, the risk of incisional hernia was greater in patients with underlying malignant disease who had undergone a colostomy than in those who had had an ileostomy (OR 5·05, 2·28 to 11·23). Conclusion Incisional hernia of the previous stoma site was common and frequently required surgical correction. Higher BMI, reversal of colostomy in patients with an underlying malignancy, stoma prolapse, parastomal hernia and hypertension were identified as independent risk factors.

Inguinal hernia repair is one of the most frequently performed procedures. An alternative to mesh repair could be herniotomy, where no mesh is placed and only minimal dissection is done. The European Hernia Society guidelines on the treatment of inguinal hernia in adult patients, which were released in 2009 and expired some time ago, states that all adult (30 years of age) male patients with a symptomatic inguinal hernia should be operated on using a mesh technique. We hypothesize that the herniotomy is a good alternative to mesh repair in young patients.In this retrospective cohort study, the postoperative complications and recurrence rate after a herniotomy procedure were studied. All patients between the ages of 18 and 40 at the time of the surgery were included from January 1st 1997 until December 31st 2010.In our cohort of 234 patients, the recurrence rate was 4.7 %. When we focus on the patients in the ages ranging from 18 to 25 years old at the time of the surgery, we found a recurrence rate of 0 versus 9.2 % in ages 26-40. These recurrence rates are comparable to those in current literature.A herniotomy seems to be an efficient procedure with acceptable recurrence rates in patients up to 30 years of age. Postoperative pain seems to be low compared to other techniques. In patients older than 30 years recurrence rates seem to increase which necessitates the use of mesh implants. The main finding is zero recurrences in patients up to 25 years of age. Because there is a limited amount of similar studies that evaluated the complications of a herniotomy, we believe these results warrant the commencement of a randomized controlled trial to add more evidence to this topic. This cohort study is a small, but important contribution to the advice to perform a randomized controlled trial. Based on the limited evidence that is known so far, this procedure might be the treatment of choice in the repair of primary inguinal hernia in young adult patients up to 30 years of age.

The transanal endoscopic operation (TEO) has proved to be an effective alternative to conventional surgery for the treatment of rectal lesions. The TEO procedure offers reduced morbidity, faster recovery and equivalent oncologic outcome. Currently, two instrument sets are available: one with three-dimensional (Wolf) and one with two-dimensional (Storz) optic capacities. The three-dimensional (3D) instrument set is considered the golden standard. Although the advantages of TEO are imposing, the procedure with the 3D armamentarium has certain technical and financial drawbacks. This study therefore aimed to compare results for the TEO 2D alternative with recently published results for 3D TEO.All consecutive patients with benign or malignant pT1 or pT2 rectal lesions undergoing TEO were prospectively followed. All procedures were performed with the 2D armamentarium using standard endoscopic instruments, a rectoscope (diameter, 4 cm; working length, 7.5-15 cm), and 5-mm Ligasure and Ultracision. Operating times, complications, hospital stay, and oncologic outcome were gathered and compared with published data.Between 2004 and 2006, 31 patients with a median age of 75 years (range, 33-87 years) underwent 31 TEOs for a total of 36 rectal lesions (29 tubulovillous adenomas and 7 adenocarcinomas). The median distance of the lesion from the anal verge was 7.5 cm (range, 5-15 cm). The median lesion diameter was 2.3 cm (range, 0.5-5.0 cm). The locations of the lesions were as follows: 18 on the dorsal, 5 on the ventral, and 5 on the lateral rectal wall. The median operating time was 55 min (range, 25-165 min), compared with 105 min reported in the literature. All the lesions except one could be radically excised. No intraoperative complications occurred. Postoperative complications occurred for three patients, all due to hemorrhage. The median hospital stay was 3 days (range, 1-21 days). During a median follow-up period of 15 months (range, 1-35 months), two recurrences took place.The study findings showed that for rectal tumors located up to 15 cm from the anal verge with a maximal diameter of 5 cm, TEO using standard laparoscopic instruments with a 2D view is feasible and provides results comparable with those associated with a 3D view and dedicated instruments. Furthermore, the 2D procedure can be performed with improved ergonomics due to movable monitors and is considerably less expensive.

Validated guidelines for the surgical and non-surgical treatment of rectal prolapse (RP) do not exist. The aim of this international questionnaire survey was to provide an overview of the evaluation, follow-up and treatment of patients with an internal or external RP.A 36-question questionnaire in English about the evaluation, treatment and follow-up of patients with RP was distributed amongst surgeons attending the congresses of the European Association for Endoscopic Surgery and the European Society of Coloproctology in 2010. It was subsequently sent to all the members of the American Society of Colon and Rectal Surgeons and the European Society of Coloproctology by e-mail.In all, 391 surgeons in 50 different countries completed the questionnaire. Evaluation, surgical treatment and follow-up of patients with RP differed considerably. For healthy patients with an external RP, laparoscopic ventral rectopexy was the most popular treatment in Europe, whereas laparoscopic resection rectopexy was favoured in North America. There was consensus only on frail and/or elderly patients with an external prolapse, with a preference for a perineal technique. After failure of conservative therapy, internal RP was mostly treated by laparoscopic resection rectopexy in North America. In Europe, laparoscopic ventral rectopexy and stapled transanal rectal resection were the most popular techniques for these patients.The treatment of RP differs between surgeons, countries and regions. Guidelines are lacking. Prospective comparative studies are warranted that may result in universally accepted protocols.

BackgroundPostoperative pain is one of the main reasons for a prolonged hospital stay after laparoscopic cholecystectomy (LC). Reduced postoperative pain might result in faster recovery and establish LC as a day-care surgical procedure. Peroperative local anaesthesia has been suggested to reduce postoperative pain. The aim of this study was to determine the effect of combined subcutaneous infiltration and intraperitoneal instillation of levobupivacaine before the start of LC on postoperative abdominal pain up to 24 h after surgery.MethodsPatients eligible for elective LC were randomized to receive preincisional infiltration and preoperative intraperitoneal instillation of 80 ml of either 0·125 per cent levobupivacaine (experimental group) or normal saline (placebo group). The primary outcome measure was abdominal pain estimated by means of a visual analogue scale at 0·5, 2, 4, 8 and 24 h after surgery.ResultsEighty of the 101 patients assessed for eligibility were randomized. There was no significant reduction in postoperative abdominal pain with levobupivacaine compared with placebo during the 24-h follow-up; the overall difference in pain score was 2·2 (95 per cent confidence interval − 4·9 to 9·3; P = 0·540). The duration of operation, use of anaesthesia, use of rescue analgesia, shoulder pain, duration of hospital stay and time to resumption of normal daily activities did not differ between the two groups.ConclusionCombined subcutaneous and intraperitoneal administration of levobupivacaine did not influence postoperative abdominal pain after LC.

Gastro-oesophageal reflux disease (GORD) is treated primarily with proton pump inhibitors. More invasive treatment is only indicated for patients with persistent symptoms or when complications occur. Anti-reflux surgery is successful in 85-90% of patients in terms of symptom control, healing of oesophagitis and normalization of oesophageal stomach-acid exposure. Laparoscopic Nissen fundoplication is the standard surgical procedure and favourable results persist for at least 5 years. Endoluminal treatment for GORD is a new development for which no long-term results are known and which can probably only be implemented in some of the patients with disease refractory to therapy. The effect of the new endoluminal treatments will have to be evaluated in randomised trials and to be compared with the medical gold standard of treatment, proton pump inhibitors, and with the surgical gold standard, laparoscopic Nissen fundoplication.
