Intestinal Intussusception by Monophasic Synovial Sarcoma: Case Report and Literature Review.

INTRODUCTION: Synovial sarcomas are rare malignant tumors of soft tissues, arising mainly from periarticular structures. Gastrointestinal localizations are unusual presentation of these rare sarcomas. METHODS: We present the case of a 56- years old man with monophasic synovial sarcoma, arising primarily from the ileum, and causing intussusception. A review of the literature was conducted to gather information about this rare sarcoma. RESULTS: We found that the criteria normally used to determine the prognosis in patients with monophasic synovial sarcoma of soft tissue are poorly applicable for gastrointestinal localizations. CONCLUSIONS: A better characterization of these tumors could identify them as a distinct entity, compared with monophasic synovial sarcomas of soft tissues.

Sigmoid intramural hematoma and hemoperitoneum: an early severe complication after stapled hemorrhoidopexy.

Stapled hemorrhoidopexy is a widely used surgical technique for treating hemorrhoids, although severe complications have been reported. The authors report a rare case of extensive ascending intramural hematoma of the sigmoid colon complicating stapled hemorrhoidopexy, with perforation and hemoperitoneum. Diagnosis was established at CT scan and treatment consisted of drainage, suturing, and diverting colostomy. This reported case is the ninth described in the literature, but, so far, it is not known what preventive measures to use in order to avoid such a rare complication. Adoption of a correct surgical technique remains the step of utmost importance in order to prevent such a severe postoperative complication.

Long-term results of laparoscopic gastric sleeve: the importance of follow-up adherence.

OBJECTIVE: This study was conducted to assess the long-term results of the Laparoscopic Sleeve Gastrectomy (LSG) in patients not compliant with follow-up, and in patients who completed a postoperative follow-up program. PATIENTS AND METHODS: The data concerning LSG patients operated from February 2011 to December 2013 were retrospectively reviewed basing on a single center database. The patients with complete long-term follow-up were scheduled in Group A, while patients who failed to attend controls for more than two years were scheduled in Group B. Long-term results (weight loss, comorbidity improvement and late complications) were compared between the two groups. RESULTS: The study population consisted of 285 patients. Of these, 101 had a complete follow-up with a mean duration of 71 ± 7.6 months (Group A). The remaining 184 patients (Group B) were not compliant with follow-up and, consequently, the mean duration of follow-up was 5.5 ± 7.3 months (p < 0.00001). A higher number of patients with insufficient weight loss was recorded in Group B with respect to Group A (78 vs. 23; p = 0.001). The number of patients with results below 25% EWL was significantly higher in Group B than in Group A (24 vs. 5; p = 0.04). In the long-term, the rate of patients with symptomatic reflux requiring medical treatment was two-fold higher in Group B than in Group A. CONCLUSIONS: The adherence to a long-term follow-up plan after LSG seems to decrease the number of patients experiencing insufficient weight loss and those at risk for developing a gastro-esophageal reflux disease.

Gastric Bypass after multiple restrictive procedures: Roux-en-Y or One Anastomosis? A retrospective multicentric study.

OBJECTIVE: When restrictive surgery fails, conversion to more malabsorptive techniques is frequently proposed. The aim of this study is to evaluate the weight loss figures between Roux-en-Y Gastric Bypass (RYGB) and One Anastomosis Gastric Bypass (OAGB) in patients who have already undergone Multiple Restrictive Procedures (MRP). PATIENTS AND METHODS: All patients who underwent conversion of Laparoscopic Sleeve Gastrectomy (LSG) to RYGB or OAGB between 2010 and 2019 were retrospectively analyzed. Only patients who had conversion for Weight Regain (WR) or Insufficient Weight Loss (IWL) after both Laparoscopic Gastric Banding (LGB) and LSG entered the study population. Finally, 44 patients underwent conversion to RYGB, and 24 patients to OAGB. RESULTS: Concerning Excess Weight Loss (%EWL) at 3, 6, 12, 24 postoperative months, the results for RYGB were 33.7%, 47.95%, 61.8%, 61.8%, while for OAGB were 38.3%, 51.9%, 63.75%, 79.45%. A significant difference was recorded in favor of OAGB at 3 (p=0.03) and 24 (p=0.046) postoperative months. % EWL at 24 months in the case of IWL was 57.8% for RYGB, while for OAGB was 72.7% (p=0.047). No significant difference was found considering patients with WR (80.9% and 80.5%; p= 0.999). Patients with better results at 24 months after surgery had a significantly longer time between sleeve and bypass than those with a lower % EWL. CONCLUSIONS: The results of the present study seem to show that both techniques give good results at 24 months in patients who have undergone MRP. However, OAGB shows overall better results, particularly in patients with IWL.

The role of antral resection in sleeve gastrectomy. An observational comparative study.

OBJECTIVE: The role of antral resection (AR) in laparoscopic sleeve gastrectomy (LSG) is still a greatly debated topic in the literature. The aim of this study was to evaluate the results and complications of AR in LSG. PATIENTS AND METHODS: In this observational comparative study, 101 patients who underwent LSG were divided into two groups based on the extent of antral resection: 1 cm from the pylorus (1-DP group), or 6 cm from the pylorus (6-DP group). The %EWL (%Excess weight loss), resolution of T2D (Type 2 Diabetes Mellitus) and GLP-1 were investigated 48 hours before surgery and 3, 6 and 12 months after LSG. Postoperative complications in the first 30 days after surgery were also compared between the two groups using the Clavien-Dindo (CD) score. RESULTS: A significant difference in %EWL was observed at 3 and 6 months in favor of the 1-DP group (38.9% and 57.8%, respectively) compared to the 6-DP group (31.4% and 49.7%, respectively). No difference in T2D resolution was observed between two groups during the follow-up period, with similar changes in GLP-1. Statistically significant differences were found between 1-DP and 6-DP group for the reintervention rate (CD III, 7.7% and 1.9%, respectively; p = 0.02) and life-threatening complications requiring intensive care unit management (CD IV, 3.8% and 0%, respectively, p = 0.03). CONCLUSIONS: In LSG, sparing the antrum is associated with a significant reduction in the rate of postoperative complications, but the metabolic and weight results are comparable to those for antrum resection.

Successful laparoscopic trans-peritoneal repair of an incisional inguinal hernia, resulting from deep lymph node dissection for melanoma: A case report.

INTRODUCTION: Deep pelvic lymph node dissection for cancer may result in incisional inguinal hernias. We present a case report of successful laparoscopic trans-peritoneal repair of a large ventral inguinal hernia that developed following ileo-inguinal lymph node dissection (CLND) for melanoma. CASE PRESENTATION: A successful 3 port laparoscopic trans-peritoneal procedure was performed on a 56-year-old female for the repair of a left inguinal hernia, developed 13 months following CLND for melanoma. The large oval 18 × 14 cm inguinal defect, with superior margins bordering the conjoint tendon and inferior margins bordering the ileo-psoas muscle, femoral vessels and nerve, was not closed in order to avoid excessive tension and was repaired by fixing a 25 × 20 cm intra-peritoneal mesh to abdominal borders at superior and lateral margins with permanent fasteners and at the inferior margin by a cyanoacrylate-glued overlap to protect femoral vessels and nerves from damage. No hernia recurrence was observed 8 months following this procedure. DISCUSSION: Incisional inguinal hernias, following CLND, are rare but present a challenge to surgeons due to the difficulty in identifying both anatomical plains and safe sites for stable repair. CONCLUSIONS: We report a laparoscopic trans-peritoneal approach for the safe, reproducible and efficacious repair of incisional inguinal hernias that result from CLND. In our opinion prevention of hernia recurrence can be achieved by a intraperitoneal large mesh fixed at superior and lateral margin borders with permanent fasteners and using cyanoacrylate glue to overlap inferior margin borders in order to prevent vessels and/or nerve injury.
