[Outcomes of Staging Laparoscopy in Eight Patients with Positive Peritoneal Washing Cytology after S-1 Administration].

AIM: The aim of this study was to clarify the clinical outcomes of staging laparoscopy(SL)for patients with positive peritonealwashing cytology(CY1P0)after S-1 administration. PATIENTS AND METHODS: Since 2007, eight CY1P0 patients who underwent SL after S-1 administration were enrolled. S-1 was administered according to the ACTS-GC and SL was performed after 8 courses of S-1 treatment. RESULTS: SL was ended with adequate observation of intra-abdominalcavity in allthe patients with a median time of 68 minutes(range: 52-76 minutes). The timing of SL was after 8 courses of S-1 administration in 6 patients, after 11 courses in 1, and 12 courses in 1. Based on the SL results, CY0P0 was attained in 6 patients; CY1P0, in 1 and CY1P1, in 1. For the 6 patients who attained CY0P0, S-1 administration was completed. For the 2 patients who attained CY1P0 and CY1P1, chemotherapy was continued. Only 1 of the patients who attained CY0P0 had peritoneal recurrence 3 months after completion of S-1 administration. CONCLUSION: When CY0P0 is detected by using SL, S-1 administration may be completed. More cases need to be studied to determine the suitable courses or timing of S-1 administration for CY0P0 patients.

[Administration of S-1 Monotherapy as Adjuvant Chemotherapy in a Patient with Advanced Gastric Cancer with HIV Infection].

A 64-year-old man with advanced gastric cancer presented with chief complaints of chest pain. His preoperative blood examination revealed positive results for serum HIV-antibody. His HIV-RNA level was 1.0×10 / 5 copies/mL, and his CD4lymphocyte count was 491 cell/mL; the patient was diagnosed with advanced gastric cancer and HIV infection. Distal gastrectomy with D2 lymphadenectomy and Roux-en-Y reconstruction were performed for treatment of the gastric cancer. Pathological examination revealed T3(SS)N3aM0, Stage III C cancer. After surgery, the patient was administered S-1 monotherapy as adjuvant treatment with antiretroviral therapy including tenofovir/emtricitabine and raltegravir. He completed 8 courses of S- 1 chemotherapy with no adverse events, such as a decrease in the CD4lymphocyte count or an increase in the HIV-RNA level. This patient with gastric cancer and HIV infection was safely treated using both antiretroviral therapy and chemotherapy owing to treatment intervention by chemotherapy and infectious diseases specialists.

A Case of Laparoscopic Resection for Carcinoma of the Gastric Remnant following Proximal Gastrectomy Reconstructed with Jejunal Interposition.

A 72-year-old Japanese man had a history of proximal gastrectomy for early gastric cancer located in the upper third of the stomach in 2007. Our usual treatment strategy for early gastric cancer in the upper third of the stomach in 2007 was open proximal gastrectomy reconstructing by jejunal interposition with a 10 cm single loop. Upper gastrointestinal fiberscopy for annual follow-up revealed a type 0-IIc-shaped tumor with ulcer scar, 4.0 cm in size, located in the gastric remnant near the jejunogastrostomy. A clinical diagnosis of cancer of the gastric remnant, clinical T1b(SM)N0M0, Stage IA, following the proximal gastrectomy was made and a laparoscopic approach was selected because of the cancer's early stage. Remnant total gastrectomy with D1 plus lymphadenectomy was carried out with five ports by a pneumoperitoneal method. Complete resection of the reconstructed jejunum was undergone along with the jejunal mesentery. Reconstruction by the Roux-en-Y method via the antecolic route was selected. Total operative time was 395 min and blood loss was 40 mL. Our patient was the first successful case of resection for carcinoma of the gastric remnant following proximal gastrectomy reconstructed with jejunal interposition in a laparoscopic approach.

Totally laparoscopic gastrectomy for early gastric cancer accompanied by huge hiatal hernia: A case report.

We herein present a case in which we used a totally laparoscopic approach for early gastric cancer accompanied by a huge hiatal hernia. An 80-year-old Japanese woman was referred with a chief complaint of dysphagia. A clinical diagnosis of early gastric cancer, T1b (SM) N0M0, stage IA, accompanied by hiatal hernia, was made. Distal gastrectomy with D1 plus lymphadenectomy was carried out. After the gastrectomy, the hernial sac was excised and the hernial orifice was closed. Reconstruction using the Roux-en-Y method was selected. The postoperative course was uneventful and she was discharged on postoperative day 10.

Autoimmune pancreatitis that developed over a 3-month observation period for IgG4-related dacryoadenitis and sialadenitis.

Autoimmune pancreatitis (AIP) that developed in a short period in a patient with IgG4-related dacryoadenitis and sialadenitis is reported. A 67-year-old man was diagnosed as having IgG4-related dacryoadenitis and sialadenitis histologically, serologically, and radiologically. At that time, the pancreas was normal on computed tomographic scanning, magnetic resonance imaging, and 18F-fluorodeoxyglucose positron emission tomography. However, AIP occurred in the pancreatic body and tail during the 3-month period of observation of the initial diseases. All IgG4-related lesions improved promptly after steroid therapy. This report emphasizes that, since IgG4-related disease can develop in other organs within a short period in a patient with IgG4-related disease, periodic imaging follow-up is necessary.
