Rare monomorphic epithelial intestinal T-cell lymphoma of the stomach with a giant gastric perforation rescued by liver-covering sutures followed by a total gastrectomy and lateral hepatectomy: a case report.

BACKGROUND: Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL), a type of peripheral T-cell lymphoma, rarely involves the stomach as the primary organ. Advanced MEITL, for which there is currently no established treatment, causes gastrointestinal perforations and is characterized by a poor response to chemotherapy. CASE PRESENTATION: A 69-year-old man had undergone chemotherapy for MEITL of the whole stomach. He subsequently developed acute abdominal pain, and computed tomography revealed a giant perforation in the anterior gastric wall adjacent to the lateral segment of the liver. The perforation was rescued through closure with liver-covering sutures. Thereafter, a total gastrectomy and a left hepatectomy were performed and he recovered enough to tolerate oral intake. However, despite ongoing chemotherapy, the patient died 83 days after the gastric perforation (10 months after being diagnosed with the lymphoma) owing to rapid progression of the MEITL. CONCLUSION: In the rare case of a giant gastric perforation after chemotherapy for gastric MEITL, rescue is possible through liver-covering sutures followed by a total gastrectomy and lateral hepatectomy.

[Short- and Long-Term Effects of Palliative Stoma Creation on Quality of Life].

Palliative stoma creation for malignant gastrointestinal obstruction improves quality of life, and advances in chemotherapy have resulted in long-term survival after stoma creation. We reviewed early and late complications in 24 patients treated with palliative stoma creation. Results: 14 men(58%)and 10 women(42%)had a median age of 60 years. Twenty-three patients(96%)were able to eat more than a porridge diet postoperatively, and the median The ColoRectal Obstruction Scoring System(CROSS)improved from 1(0-3)to 4(2-4)(p<0.001). Postoperative complications(all Clavien-Dindo grades)were observed in 10 patients(42%), with a longer postoperative hospital stay in the complication group than in the group without complication(median 34 days: 17 days, p=0.026). When divided into long-term survivors and short- term survivors based on a median overall survival of 101 days, more stoma prolapse occurred in the long-term survivors(4 cases 33% vs 0 cases 0%, p=0.028), one of which required repair surgery. Conclusion: Long-term survivors after exploratory stoma creation are more likely to develop a stoma prolapse. Careful surgical manipulation and postoperative support system including stoma care are important.

Superior perianastomotic fluid collection in the early postoperative period affects pseudoaneurysm occurrence after pancreaticoduodenectomy.

PURPOSE: Pseudoaneurysm (PA) after pancreaticoduodenectomy (PD) is a harmful complication due to postoperative pancreatic fistula. However, the preventive method for PA is unclear. This study aimed to assess the risk factors for PA after PD and to evaluate the clinical features of patients with PA. METHODS: Medical records of 54 patients who underwent PD and developed clinically relevant postoperative pancreatic fistula (POPF) were retrospectively reviewed. We evaluated postoperative computed tomography (CT) findings, including the perianastomotic fluid collection (PFC) location on postoperative day 4. Perioperative findings and postoperative CT findings were compared between patients with and without PA after PD. RESULTS: The PA group included nine patients (17%). The median postoperative day of diagnosis of PA was 17 (range, 7-33). The PA locations were the gastroduodenal artery stump (n = 3), dorsal pancreatic artery (DPA) stump from the common hepatic artery (n = 4), DPA stump from the replaced right hepatic artery (n = 1), and inferior pancreaticoduodenal artery stump (n = 1). The prevalence of falciform ligament wrap to the hepatic artery was lower (33% vs. 78%, p = 0.014) and superior PFC prevalence was higher (100% vs. 58%, p = 0.019) in the PA group than in the non-PA group. Superior PFC reached the dorsal part of the caudate lobe of the liver in all patients with PA. Furthermore, all PAs occurred at the arteries that could not be wrapped by the falciform ligament. CONCLUSION: Prevention of superior PFC and falciform ligament wrapping may reduce PA occurrence after PD with clinically relevant POPF.

[A Case of Synchronous Quadruple Cancers Treated with Neoadjuvant Chemotherapy Followed by Surgery].

The patient is male in his 60's. He underwent endoscopic examination for anemia, which was found during screening of high PSA value. Endoscopic examination revealed a gastric cancer and 3 colorectal cancers. Histological results from biopsy was HER2 positive poorly differentiated adenocarcinoma in gastric tumor and moderately differentiated adenocarcinoma in colorectal tumor. Chest CT showed a pulmonary nodule in the middle right lung. Histological diagnosis was TTF-1 positive adenocarcinoma, meaning primary lung cancer. Histological examination of prostate biopsy also showed adenocarcinoma. Clinical stages were Stage III B of gastric cancer, Stage III a of colorectal cancer, Stage I A of lung cancer and Stage I of prostate cancer. Neoadjuvant chemotherapy for gastric cancer was performed because gastric cancer with advanced clinical stage was regard as a prognostic factor. Neoadjuvant chemotherapy shrinked gastric and colorectal cancers, so we performed distal gastrectomy for gastric cancer and super low anterior resection for colorectal cancer. Patient was discharged 22 days after operation without any serious adverse events. Hormonal treatment for prostate cancer and radiation therapy for lung cancer were performed. Now this patient is alive without any recurrence.
