Background: Wandering spleen is a rare condition, which is characterized by augmented mobility of the spleen, due to congenital or acquired causes. It is more frequent in multiparous women, but only a few cases are reported during pregnancy. Wandering spleen is usually asymptomatic until the onset of its possible complications, and this can mislead clinicians in reaching the correct diagnosis. Case presentation: We report the case of a wandering spleen with acute splenic infarction in a pregnant woman and its minimally invasive surgical treatment, focusing on the clinical and radiological findings that could mislead or drive clinicians to the right diagnosis, or a potential disaster. Conclusions: Splenic preservation in the wandering spleen where it is safe and possible is the main goal of the treatment. Clinical and radiological findings are the most relevant elements to drive surgical treatment. To reach the best and opportune treatment for the patient, the wandering spleen is an insidious condition and must be included in the differential diagnosis in the acute abdomen diagnostic process.

Background: The aim of lymphadenectomy is to clear all the metastatic nodes achieving a complete removal of the tumor; nevertheless, its role in gastric cancer has been very much debated.Materials and Methods: The frequency of node metastasis in each lymphatic station according to the International Gastric Cancer Association, was studied in 545 patients who underwent D2 or D3 lymphadenectomy from June 1988 to December 2002.Results: Upper third early cancers have shown an involvement of N2 celiac nodes in 25%. In advanced cancers, there was a high frequency of metastasis in the right gastroepiploic (from 10% in T2 to 50% in T4) and in the paraaortic nodes (26% in T2, 32% in T3, 38 % in T4). N3 left paracardial nodes involvement was observed in an important share of middle third tumors (17% in T3, 36% in T4). Splenic hilum nodes metastasis were common in T3 and T4 cancers located in the upper (39%) and middle (17%) stomach. N2 nodal involvement was frequent in lower third advanced cancers. Metastasis in M left paracardial and short gastric nodes were observed in a small percentage of cases.Conclusion: Given the nodal diffusion in our gastric cancer patients, extended lymphadenectomy is still a rationale to obtain radical resection.

Background: Recently, in the field of abdominal wall repair surgery, some minimally invasive procedures introduced the use of staplers to provide a retromuscular prosthetic repair. However, to the knowledge of the authors, there are little data in the literature about the outcomes of stapled sutures adoption for midline reconstruction. This study aims to investigate the biomechanics of stapled sutures, simple (stapled), or oversewn (hybrid), in comparison with handsewn suture. From the results obtained, we tried to draw indications for their use in a clinical context. Methods: Human cadaver fascia lata specimens, sutured (handsewn, stapled, or hybrid) or not, underwent tensile tests. The data on strength (maximal stress), ultimate strain (deformability), Young's modulus (rigidity), and dissipated specific energy (ability to absorb mechanical energy up to the breaking point) were recorded for each type of specimens and analyzed. Results: Stapled and hybrid suture showed a significantly higher strength (handsewn 0.83 MPa, stapled 2.10 MPa, hybrid 2.68 MPa) and a trend toward a lower ultimate strain as compared to manual sutures (handsewn 344%, stapled 249%, hybrid 280%). Stapled and hybrid sutures had fourfold higher Young's modulus as compared to handsewn sutures (handsewn 1.779 MPa, stapled 7.374 MPa, hybrid 6.964 MPa). Handsewn and hybrid sutures showed significantly higher dissipated specific energy (handsewn 0.99 mJ-mm3, stapled 0.73 mJ-mm3, hybrid 1.35 mJ-mm3). Conclusion: Stapled sutures can resist high loads, but are less deformable and rigid than handsewn suture. This suggests a safer employment in case of small defects or diastasis (< W1 in accord to EHS classification), where the presumed tissutal displacement is minimal. Oversewing a stapled suture improves its efficiency, becoming crucial in case of larger defects (> W1 in accord to EHS classification) where the expected tissutal displacement is maximal. Hybrid sutures seem to be a good compromise. [ABSTRACT FROM AUTHOR]

Objective: To find out the extent of involvement of the para-aortic nodes in patients with adenocarcinoma of the gastric cardia. Design: Open prospective study. Setting: Teaching hospital, Italy. Subjects: 23 patients with advanced adenocarcinoma of the cardia (type II, n = 10, and type III, n = 13) who were treated by total gastrectomy with resection of the distal oesophagus and extended lymphadenectomy (D4) between January 1997 and June 1999. These were compared with 21 patients with advanced carcinoma of the proximal third of the stomach who had total gastrectomy with D4 lymphadenectomy during the same period. Lymph nodes were retrieved immediately postoperatively and assigned to the appropriate station according to the classification of the Japanese Research Society for Gastric Cancer. Main outcome measures: Number of para-aortic and other nodes involved. Results: 22 of the 23 patients had lymph node metastases, and in 5 the para-aortic nodes were involved (N4). N3 lymph nodes were involved in only 1 patient, despite involvement of para-aortic nodes. Among the 5 patients with N4 metastases, 1 had only N1 metastases in addition, with no involvement of N2 or N3 nodes. Patients with involved N4 nodes had more nodes involved overall than those who did not (mean (SD) 17 (5) compared with 8 (12)). Conclusions: 5/23 patients with advanced carcinoma of the cardia had involved para-aortic nodes. This may have some prognostic value, but larger studies of D4 lymphadenectomy specimens is required.

Background: Inguinal hernioplasty is the most frequently performed operation in the Western world today. Although the laparoscopic approach for inguinal hernia repair has shown excellent results in terms of complications and recurrences, the anterior approach is still the most used. Postoperative pain and recurrences are the most widely studied complications in both approaches, but there is little information about the often more troublesome rare complications of laparoscopic surgery and their treatment. Methods: In the period from January 1, 2014 to December 31, 2019, 1874 hernioplasty operations were performed with the transabdominal approach and recorded prospectively in the Wall Hernia Group database. The mean follow-up was 47 months (range 3-64 months). All less frequent complications were analyzed and a literature review was carried out to assess the presence of similar cases and their treatment in other series. Results: Eight cases of rare complications were identified and subdivided according to the Clavien-Dindo classification. They included a bowel perforation, 4 cases of bleeding, 2 bowel obstructions, and an injury to the motor branch of the obturator nerve. The postoperative course in these patients was significantly longer than in patients with a regular postoperative course. In 2 cases the complication occurred during the first admission, while the remaining 6 patients had to be readmitted within 30 days after discharge. Conclusions: Although serious postoperative complications in laparoscopic inguinal hernioplasty are rare, all surgeons, also those who have completed the learning curve, should be aware of their possible occurrence.

Background: In patients with locally advanced rectal cancer treated by neoadjuvant chemoradiation, pathological complete response in the surgical specimen is associated with favourable long-term oncologic outcome. Based on this observation, nonoperative management is being explored in the subset of patients with clinical complete response. Whereas, patients with poor response have a high risk of local and distant recurrence, and appear to receive no benefit from standard neoadjuvant chemoradiation. Therefore, in order to develop alternative treatment strategies for non responding patients, predictive and prognostic factors are highly needed. Accumulating clinical observations indicate that elevated platelet count is associated with poor outcome in different type of tumors. In this study we investigated the predictive and prognostic impact of elevated platelet count on pathological response and long-term oncologic outcome in patients with locally advanced rectal cancer undergoing neoadjuvant chemoradiation.Methods: A total of 965 patients were selected from prospectively maintained databases of seven Centers within the SICO Colorectal Cancer Network. Patients were divided into two groups based on a pre-neoadjuvant chemoradiation platelet count cut-off value of 300 × 109/L identified by receiver operating characteristic curve considering complete pathological response as the outcome.Results: Complete pathological response rate was lower in patients with elevated platelet count (12.8% vs. 22.1%, p = 0.001). Mean follow-up was 50.1 months. Comparing patients with elevated platelet count with patients with not elevated platelet count, 5-year overall survival was 69.5% vs.76.5% (p = 0.016), and 5-year disease free survival was 63.0% vs. 68.9% (p = 0.019). Local recurrence rate was higher in patients with elevated platelet count (11.1% vs. 5.3%, p = 0.001), as higher was the occurrence of distant metastasis (23.9% vs. 16.4%, p = 0.007). At multivariate analysis of potential prognostic factors EPC was independently associated with worse overall survival (HR 1.40, 95% CI 1.06-1.86), and disease free survival (HR 1.37, 95% CI 1.07-1.76).Conclusions: In locally advanced rectal cancer elevated platelet count before neoadjuvant chemoradiation is a negative predictive and prognostic factor which might help to identify subsets of patients with more aggressive tumors to be proposed for alternative therapeutic strategies.

Background Methods. The investigation involved 117 patients with a cancer of the lower third of the stomach invading the serosa (pT3) who underwent R0 resection with at least D2 lymphadenectomy between 1988 and 1998 at three different Italian centers. The choice of surgical procedure (40 total gastrectomies and 77 subtotal gastrectomies) was based on the preference of the surgeon; none of the patients underwent splenectomy. The Cox regression model was used to evaluate the prognostic significance of the type of surgery (subtotal versus total gastrectomy), controlling for age, sex, histology, nodal involvement, and surgical center. Results. The morbidity and mortality rates did not vary significantly according to the type of surgery. Patients undergoing subtotal gastrectomy presented a better disease-related survival than patients undergoing total gastrectomy (P = 0.011): the median survival times were, respectively, 38 months and 23 months, and the overall cumulative 5-year survival rates (95% confidence intervals [CI]) were, respectively, 36% (22%–50%) and 22% (11%–37%). On univariate analysis, the relative risk (RR) of disease-related death was 1.84 (1.14–2.97) after total gastrectomy, with respect to subtotal gastrectomy. This difference was blunted on multivariate analysis (RR, 1.66; 0.99–2.78): in the final model, only nodal metastasis was a significant prognostic factor, while type of surgery had a borderline significance (P = 0.057). Conclusions. Survival after subtotal gastrectomy is not lower than that after total gastrectomy in patients with tumor of the antrum invading the serosa. The role of subtotal or total gastrectomy in the treatment of advanced gastric cancer of the antrum with serosal invasion was investigated. [ABSTRACT FROM AUTHOR]
