[A case of small intestinal endometriosis with bowel obstruction and perforation].

A 47-year-old woman was referred to our hospital with recurring lower abdominal pain persisting for more than 2 weeks. Imaging modalities showed small bowel obstruction caused by a mass lesion in the terminal ileum. Despite undergoing fasting, rehydration, and decompression through an ileus tube, her symptoms persisted. Furthermore, the condition deteriorated on day 4, with the onset of her menstrual period. An emergency surgery was conducted on the 7th day after hospitalization. Surgical observations indicated severe stenosis around the ileocecal valve and ileal perforation approximately 40cm from the oral stricture. As a result, ileocecal resection was performed. Pathological examination revealed endometrial tissue infiltration through the mucosal lamina propria to the ileal subserosa. Thus, the patient was identified with intestinal endometriosis of the ileocecum. Endometriosis of the small bowel is an uncommon condition that eventually causes intractable bowel obstruction. Although preoperative diagnosis is considered challenging, intestinal endometriosis should be included in the differential diagnosis in cases of bowel obstruction in women of childbearing age.

Three-year outcomes of a randomized phase III trial comparing adjuvant chemotherapy with S-1 plus docetaxel versus S-1 alone in stage III gastric cancer: JACCRO GC-07.

PURPOSE: The second planned interim analysis (median follow-up 12.5 months) in a phase III trial of postoperative adjuvant chemotherapy for stage III gastric cancer revealed significant improvement in relapse-free survival (RFS) for S-1 plus docetaxel over S-1 alone. Although enrollment was terminated on the recommendation of the independent data and safety monitoring committee, we continued follow-up and herein report on 3-year RFS, the primary endpoint. PATIENTS AND METHODS: Patients with histologically confirmed stage III gastric cancer who underwent gastrectomy with D2 lymphadenectomy were randomly assigned to receive adjuvant chemotherapy with either S-1 plus docetaxel or S-1 alone. In the S-1 plus docetaxel group, S-1 was given orally for 2 weeks followed by 1 week of rest for seven courses, and docetaxel was given intravenously on day 1 of the second to seventh courses. The combination therapy was followed by S-1 monotherapy for up to 1 year. RESULTS: The 3-year RFS rate of the S-1 plus docetaxel group was 67.7%. This was significantly superior to that of 57.4% in the S-1 group (hazard ratio [HR] 0.715, 95% CI 0.587-0.871, P = 0.0008). This translated into a significant benefit in the 3-year overall survival (OS) rate in the S-1 plus docetaxel group (77.7% versus 71.2%, HR 0.742, 95% CI 0.596-0.925, P = 0.0076). CONCLUSION: On 3-year follow-up data, postoperative adjuvant therapy with S-1 plus docetaxel was confirmed to improve both RFS and OS and can be recommended as a standard of care for patients with stage III gastric cancer treated by D2 dissection.

Laparoscopic totally extraperitoneal repair for recurrent inguinal bladder hernia: A case report.

We present a case of a recurrent inguinal bladder hernia that was previously unsuccessfully operated on three times and was repaired using totally extraperitoneal repair (TEP). A 79-year-old man presented with a right inguinal swelling that had been treated three times on the same side with anterior approaches. Computed tomography confirmed a recurrent inguinal bladder hernia. TEP was performed after identifying the bladder hernia preoperatively, with previous surgeries that used a plug-and-patch technique through an anterior approach. The extraperitoneal approach allowed the bladder to be reduced without injury and the hernia to be safely repaired using a 3D Max® Light Mesh. The postoperative recovery was uneventful, with no recurrence after 1 year. TEP facilitates the diagnosis and repair of bladder hernias, emphasizing the importance of preoperative diagnosis and the efficacy of endoscopic procedures in bladder hernia repair, even in recurrent cases.

Laparoscopic Repair Following a Delayed Presentation of Traumatic Diaphragmatic Hernia: A Case Report.

Traumatic diaphragmatic hernia is a rare condition that occurs after trauma, and some patients have a delayed presentation. A laparoscopic approach is rarely used to repair traumatic diaphragmatic hernias. We encountered a case of asymptomatic diaphragmatic hernia diagnosed after a comprehensive medical examination. A 71-year-old woman was diagnosed with a delayed presentation of traumatic diaphragmatic hernia with prolapse of the greater omentum owing to a traffic injury 20 years ago. Surgery was performed laparoscopically using three ports, and intraoperative respiratory management was performed using a double-lumen tube. The 2.5-cm-diameter hernial orifice was sutured under contralateral one-lung ventilation after the greater omentum was returned to the abdominal cavity. The patient's postoperative course was uneventful, and she was discharged on the third day. Intraoperative strategies such as respiratory management and the laparoscopic approach play a crucial role in ensuring favorable postoperative outcomes. The last follow-up was at six months post-operation, and the patient was doing well.

Lipomatous Pseudohypertrophy of the Pancreas Taking the Form of Huge Massive Lesion of the Pancreatic Head.

A 70-year-old woman presented with hypogastric pain. Computed tomography and magnetic resonance imaging revealed a retroperitoneal tumor 18.0 cm in diameter with fatty tissue density, ventrally compressing the pancreatic head. We suspected a well-differentiated liposarcoma compressing the pancreas. At laparotomy, the tumor mass was the size of an infant's head; its center was located in the area corresponding to the pancreatic uncus. It was continuous with the pancreatic parenchyma through a poorly demarcated border, and we resected as much of the tumor mass as possible while conserving the pancreatic capsule. Histopathological examination indicated lipomatous pseudohypertrophy of the pancreas with proliferation of mature fatty tissue as the main constituent. At the periphery, islands of acinar tissue were retained among the fatty infiltration, which also contained branches of the pancreatic duct and islets of Langerhans. Previous reports have stated that this disorder only causes fatty replacements throughout the pancreas or in the pancreatic body and tail; however, in this patient, imaging and macroscopic examination revealed no fatty replacements in the pancreatic body and tail. We report this case, which we consider extremely rare, along with a brief review of the literature.
