Long-term comparison of boomerang-shaped jejunal interposition and Billroth-I reconstruction after distal gastrectomy.

BACKGROUND: Billroth-I (BI) is a simple, physiological method of reconstruction following distal gastrectomy. In actuality, postoperative QOL is by no means favorable due to the high incidence of post-gastrectomy syndrome. The aim of this study is to assess the safety and efficacy of boomerang-shaped jejunal interposition (BJI) after distal gastrectomy. METHODS: Sixty-six patients with early gastric cancer underwent the BI procedure (n = 33) or BJI (n = 33) after distal gastrectomy, following which they were compared for 5 years. Tumor characteristics, operative details, postoperative complications and complaints, number of meals, and body weight were analyzed. Patients were followed up by endoscopy every 12 months. RESULTS: There were no significant differences in the incidence of postoperative complications. The incidence of heartburn (30 vs. 0 %, P = 0.0009) and oral bitterness (33 vs. 6 %, P = 0.0112) were significantly lower in the BJI cases. Endoscopic findings revealed significantly lower incidences of reflux esophagitis (24 vs. 0 %, P = 0.0051) and remnant gastritis (70 vs. 3 %, P < 0.0001) in the BJI group. The incidence of food stasis was low in both groups (12 vs. 15 %). In the BJI group, 30 patients (90 %) were eating 3 meals/day within 12 months, whereas in the BI group, 16 patients (48 %) were still eating 5 meals/day at 12 months or later. CONCLUSIONS: BJI is as safe as BI, but is better in terms of improvement in bile reflux and food intake without stasis. This procedure, therefore, appears to be a useful method for reconstruction after distal gastrectomy.

Sigmoid colon cancer with mediastinal lymph node metastases.

Mediastinal lymph node metastasis from colorectal cancer is rarely seen. We herein report on a 74-year-old man who was hospitalized with multiple brain metastases and mediastinal lymph node metastasis from an adenocarcinoma of the sigmoid colon. A preoperative brain magnetic resonance image showed multiple brain tumors, and a chest computed tomography (CT) scan indicated a mediastinal tumor. CT-guided aspiration biopsy cytology of the mediastinal tumor showed metastatic adenocarcinoma from a digestive tract tumor. Barium enema and sigmoid colonoscopy showed that the cancer was located in the sigmoid colon. Laparoscopic assisted sigmoidectomy with lymph node dissection was performed. Pathological findings of the specimen showed a moderately differentiated adenocarcinoma that invaded to the subserosa, but no evidence of lymph node metastasis was found. The patient was discharged 3 weeks after the operation and died 3 months later.

[A case of effective treatment of oral TS-1 and intravenous MMC administration for multiple metastases of gastric cancer].

A 49-year old man underwent distal gastrectomy (D3) for circumferential type 3 cancer at the gastric antrum and cholecystectomy in September 2002. During the surgery, multiple metastases were observed predominantly in the left lobe of the liver, and lateral segmentectomy was performed as non-curative (curability-C) resection leaving the small metastases in the right lobe of the liver. Based on the results of chemo-sensitivity tests (5-FU 15.0%, CDDP 34.0%, MMC 35.3%, TXT 0.0%), we started to administer TS-1 (100 mg/day for 4 weeks followed by a 2-week rest interval) and MMC (10 mg/body on day 1). Due to leukocytopenia, the regimen was changed to TS-1 (100 mg/day for 4 weeks followed by a 2-week rest interval) and MMC (4 mg/body every other week [day 1, 14]) from the second course. Levels of tumor markers dropped and liver metastatic lesions remarkably decreased in size by CT after the third course. In conclusion, a combination of TS-1/MMC may be regarded as one option for postoperative adjuvant chemotherapy for outpatients.
