[Intra-Abdominal Desmoid Tumor in a Young Man without Laparotomy History-A Case Report].

During a follow-upstudy after the treatment of T cell lymphoma, a 21-year-old man reported an intra-abdominal mass in his right lower abdomen, which was then confirmed using abdominal CT. Therefore, recurrence was suspected due to his medical history. To perform a biopsy, laparoscopic surgery was scheduled, which located the tumor in the mesentery of the terminal ileum, involving the cecum. For this, laparoscopic ileocecal resection was performed. After 7 days, the patient was discharged without complications. Histopathologically, the mass was diagnosed as a desmoid tumor via immunostaining. It is relatively rare that an intra-abdominal desmoid tumor occurs without risk factors in a young man. We herein report a case of an intra-abdominal desmoid tumor, which was successfully treated using laparoscopic surgery.

[A Case of Ampullary Region Carcinoma in a Young Woman - A Case Report].

A 19-year-old woman with general fatigue who initially consulted a local hospital was referred to us for further examination of jaundice. Contrast-enhanced CT revealed apparent dilatation of the bile duct. Gastrointestinal endoscopy exhibited a tumor of the papilla of Vater(adenocarcinoma, tub2). Thus, pylorus-preserving pancreatoduodenectomy with D2 lymph node dissection was performed. Pathologically, she was diagnosed with a T3bN1M0, pStage ⅡB tumor. After surgery, the patient underwent adjuvant chemotherapy containing S-1 for 6 months. We herein report a juvenile case of ampullary region carcinoma that was successfully treated.

[Curatively Resected Stage â £Gastric Cancer with Positive Peritoneal Cytology Due to SOX Therapy-A Case Report].

A 70-year-old man with epigastralgia who initially visited a local hospital was referred to us for further examination. Gastrointestinal endoscopy exhibited a type 3 tumor of the stomach from the body to the antrum(adenocarcinoma, por1). Contrast-enhanced CT revealed thickness in the wall of the gastric body with bulky lymph nodes and ascites. Staging laparoscopy showed that the patient was diagnosed with sStage Ⅳ gastric cancer with positive peritoneal cytology. Therefore, SOX therapy was administered. Subsequently, total gastrectomy with D2 lymph node dissection was performed, since the primary tumor and lymph nodes were significantly reduced. Histopathologically, the residual lesion was only observed in the mucosal layer without lymph node metastases. We herein report a case of Stage Ⅳ gastric cancer, which was successfully treated by conversion surgery after SOX therapy.

Lower geriatric nutritional risk index predicts postoperative pancreatic fistula in patients with distal pancreatectomy.

Postoperative pancreatic fistula (POPF) is a common complication following pancreatic resection. It leads to increased medical costs, and longer hospital stays. However, the risk factors of POPF are still unclear, and therefore, this urgent clinical issue should be resolved. The geriatric nutritional risk index (GNRI) is tool to assess the nutritional status using body weight, and serum albumin value, particularly in elderly patients. On the other hand, POPF is associated with body mass index (BMI). Thus, the present study aimed to investigate whether GNRI can predict the risk of POPF in patients after distal pancreatectomy (DP). We conducted a retrospective cohort study involving 37 patients who were treated at the Department of Digestive Surgery, Kawaguchi Municipal Medical Center between January 2007 and June 2018. All patients were subjected to nutritional screening using GNRI, and were followed up after DP for postoperative complications including POPF. In addition, risk factors of POPF, and patient's height, BMI, and preoperative laboratory values were analyzed. POPF was observed in 7 of the 37 (19%) patients. Those with a POPF had significantly lower GNRI values than those without POPF (P<0.001). Receiver operating characteristic curve analysis was performed to determine a cut-off value of GNRI, which indicated an increased risk of POPF. This value was determined as 96 (sensitivity: 71.4%, specificity: 86.7%, likelihood ratio: 5.36). Univariate analysis confirmed that a GNRI of <96 was significantly associated with POPF (P=0.005), and a multivariate logistic regression analysis revealed that a GNRI of <96 was significant independent predictor of POPF (P=0.005), suggesting its utility for assessing the risk of POPF following DP.

Intestinal obstruction caused by primary adenosquamous cell carcinoma of the small intestine: A case report and review of the literature.

Primary adenosquamous cell carcinoma (ASCC) arising from the ileum is an exceptionally rare malignant neoplasm exhibiting mixed glandular and squamous differentiation. The clinicopathological characteristics of ASCC have not been clearly determined due to its rarity. We herein report a case of a 74-year-old man with a successfully treated ASCC of the ileum. The patient visited a medical clinic due to abdominal pain. Abdominal computed tomography imaging revealed an intestinal tumor in the ileum. Prior to undergoing capsule endoscopy, the patient complained of severe abdominal pain due to intestinal obstruction from the patency capsule and the tumor. Thus, the patient was referred to our hospital for emergency surgery. Upon relieving the obstruction by partial resection of the ileum, an impacted patency capsule with a tumor with ulceration was identified. On histological examination, the tumor consisted of malignant glandular and squamous cell elements. The postoperative course was uneventful, without complications. The patient subsequently received adjuvant chemotherapy with oxaliplatin and capecitabine for 6 months. The patient has no evidence of recurrence 20 months after surgery. To the best of our knowledge, only 8 cases of ASCC have been reported in the English literature to date. This case serves as an important reminder to consider small intestinal carcinoma, including ASCC, in the differential diagnosis of intestinal obstruction.

Geriatric nutritional risk index predicts surgical site infection after pancreaticoduodenectomy.

Surgical site infections (SSIs) are a well-known potential complication of surgery. They are assocaited with preoperative malnutrition and lead to increased medical costs and longer hospital stays. Therefore, surgeons should appropriately identify patients who are at a high risk. The geriatric nutritional risk index (GNRI) is a tool, increasingly utilized to assess the degree of malnutrition, particularly in elderly patients. Therefore, the present study attempted to validate whether GNRI could predict the risk of SSI in patients following pancreaticoduodenectomy (PD). A cohort study was retrospectively conducted on 106 patients in the Department of Digestive Surgery, Kawaguchi Municipal Medical Center, Japan from January 2007 to December 2017. All patients were subjected to nutritional screening using GNRI and followed up for the occurrence of postoperative complications, including SSI post PD. Additionally, risk factors for developing SSI, and the patient's height, body mass index and preoperative laboratory values were documented. Patients were divided into SSI (n=15) and non-SSI (n=91) groups with a determined incidence of 14.2% (15/106) for SSI. The results revealed that the SSI group had GNRI values that were significantly reduced compared with the non-SSI group (P<0.001). Receiver operating characteristic curve analysis was performed to determine the cut-off value of GNRI that conferred an increased risk of SSI; it was determined as 94 (sensitivity 80.0%, specificity 83.5%). Univariate analysis confirmed that a GNRI <94 was significantly associated with SSI (P<0.001), whereas multivariate logistic regression analysis revealed that a GNRI <94 was independently associated with SSI following PD (relative risk=1.73, 95% confidence interval=1.23-2.43; P<0.001). Therefore, a GNRI <94 is a potential predictive marker for SSI risk following PD.

Prostate cancer with supraclavicular lymphadenopathy and bulky abdominal tumor.

A 73-year-old man with suspected lymphoproliferative disorder was introduced to our hospital. The patient demonstrated palpable hard masses in the abdomen. Enhanced computed tomography of the abdomen and pelvis revealed a bulky mass of para-aortic lymph nodes. Biopsy of left-sided supraclavicular lymph nodes revealed metastatic adenocarcinoma. Serum tumor markers were examined, revealing prostate-specific antigen (PSA) levels of 3,354.0 ng/ml. Rectal examinations revealed a stony-hard prostatic mass. Biopsy of the prostate disclosed poorly to moderately differentiated adenocarcinoma. Although metastases to the supraclavicular lymph nodes are rare in prostate cancer, it should be distinguished from malignant lymphoma and other malignancies.
