Long-term quality-of-life comparison of total gastrectomy and proximal gastrectomy by postgastrectomy syndrome assessment scale (PGSAS-45): a nationwide multi-institutional study.

BACKGROUND: Although proximal gastrectomy (PG) is widely accepted as a function-preserving operation for early upper-third gastric cancer, postoperative disorders, such as reflux or gastric stasis, have often been pointed out. From the perspective of postoperative disorder, the choice of total gastrectomy (TG) or PG for such cancers is still controversial. By using the newly developed Postgastrectomy Syndrome Assessment Scale (PGSAS)-45, the quality of life after TG and PG was compared. METHODS: The PGSAS-45 consists of 45 items composed of the SF-8 and GSRS scales and 22 new items. The main outcomes are measured by seven subscales (SS) covering symptoms, physical and mental component summary (SF-8), meals (amount and quality), ability to work, dissatisfaction for daily life, and change in body weight. A total of 2,368 eligible questionnaires were acquired from 52 institutions. From these, 393 patients with TG and 193 patients with PG were selected and compared. RESULTS: The PG was better than TG in terms of body weight loss (TG 13.8% vs. PG 10.9%; p = 0.003), necessity for additional meals (2.4 vs. 2.0; p < 0.001), diarrhea SS (2.3 vs. 2.0; p = 0.048), and dumping SS (2.3 vs. 2.0; p = 0.043). There were no differences in the other main outcome measures. CONCLUSIONS: Proximal gastrectomy appears to be valuable as a function-preserving procedure for early upper-third gastric cancer.

Postoperative bile leakage managed by interventional intrabiliary ethanol ablation.

We report a case of postoperative bile leakage that was successfully managed by intrabiliary ethanol ablation. A 68-year-old man with peritoneal and liver metastases from a jejunal gastrointestinal stromal tumor (GIST), which were refractory to molecular-targeted agents, underwent extended left lobectomy and peritoneal tumor resection. Bile leakage from the drainage tube persisted at a constant volume of 100 ml per day. On the 20th postoperative day, fistulography through a drainage tube and endoscopic cholangiography revealed biliary leakage from the bile ducts of segments 5 and 1. Since these bile ducts did not communicate with the proximal hilar bile ducts, two 5F balloon catheters were separately advanced into the leaking bile ducts via the drainage tube on day 30, and 1 ml absolute ethanol was injected into both of these catheters for 10 minutes. After three sessions of ethanol ablation, the bile leakage stopped. Although the bile leakage from segment 1 relapsed five days later, it gradually decreased and then stopped again until day 70. Intrabiliary ethanol ablation using the interventional technique is useful for managing bile leakage after hepatectomy when the leaking distal bile duct is isolated from the proximal biliary tree.

Analysis of anatomic variants of mesenteric veins by 3-dimensional portography using multidetector-row computed tomography.

BACKGROUND: It is important to be aware of mesenteric venous variants to perform peripancreatic surgery. We investigated the usefulness of 3-dimensional (3-D) portography. METHODS: Vessels were reconstructed using computer software in 102 patients undergoing multidetector-row computed tomography (MDCT) scheduled for gastrointestinal or hepatobiliary-pancreatic surgery. RESULTS: The superior mesenteric vein (SMV) was composed of single and double trunks around the splenoportal confluence in 78 and 24 patients, respectively. The inferior mesenteric vein joined the splenic vein (68.5%), SMV (18.5%), and splenoportal confluence (7.6%). The left gastric vein joined the splenic vein (46.3%), portal vein (39.0%), and splenoportal confluence (14.7%). Seventy-nine patients showed a gastrocolic trunk, mostly composed of the right gastroepiploic vein and veins from the colonic hepatic flexure. Intraoperative findings were identical to 3-D diagnosis in 68 gastrectomized and 9 pancreatectomized patients. CONCLUSION: Although mesenteric venous tributaries are complex, 3-D portography is helpful for surgeons to safely perform peripancreatic surgery.
