Curative two-stage resection for synchronous triple cancers of the esophagus, colon, and liver: Report of a case
AbstractIntroductionCases of synchronous triple cancers of the esophagus and other organs curatively resected are rare.Presentation of caseA 73-year-old man was admitted to our hospital with bloody feces. He was diagnosed with synchronous triple cancers of the esophagus, colon, and liver. We selected a two-stage operation to safely achieve curative resection for all three cancers. The first stage of the operation comprised a laparoscopy-assisted sigmoidectomy and partial liver resection via open surgery. The patient was discharged without complications. Thirty days later, he was readmitted and thoracoscopic esophagectomy was performed. Although pneumonia-induced pulmonary aspiration occurred as a postoperative complication, it was treated conservatively. The patient was discharged on postoperative day 24.DiscussionEsophagectomy is a highly invasive procedure; thus, simultaneous surgery for plural organs, including the esophagus, may induce life-threatening, severe complications. Two-stage surgery is useful in reducing surgical stress in high-risk patients. For synchronous multiple cancers, the planning of two-stage surgery should be considered for each cancer to maintain organ function and reduce the stress and difficulty of each stage.ConclusionWe successfully treated synchronous triple cancers, including esophageal cancer, by a two-stage operation
Daikenchuto accelerates the recovery from prolonged postoperative ileus after open abdominal surgery : a subgroup analysis of three randomized controlled trials
Purpose
Prolonged postoperative ileus (POI) is a common complication after open abdominal surgery (OAS). Daikenchuto (DKT), a traditional Japanese medicine that peripherally stimulates the neurogenic pathway, is used to treat prolonged POI in Japan. To analyze whether DKT accelerates the recovery from prolonged POI after OAS, we conducted a secondary analysis of three multicenter randomized controlled trials (RCTs).
Methods
A secondary analysis of the three RCTs supported by the Japanese Foundation for Multidisciplinary Treatment of Cancer (project numbers 39-0902, 40-1001, 42-1002) assessing the effect of DKT on prolonged POI in patients who had undergone OAS for colon, liver, or gastric cancer was performed. The subgroup included 410 patients with no bowel movement (BM) before the first diet, a DKT group (n = 214), and a placebo group (n = 196). Patients received either 5 g DKT or a placebo orally, three times a day. The primary endpoint was defined as the time from the end of surgery to the first bowel movement (FBM). A sensitivity analysis was also performed on the age, body mass index and dosage as subgroup analyses.
Results
The primary endpoint was significantly accelerated in the DKT group compared with the placebo group (p = 0.004; hazard ratio 1.337). The median time to the FBM was 113.8 h in the placebo group and 99.1 h in the DKT treatment group.
Conclusions
The subgroup analysis showed that DKT significantly accelerated the recovery from prolonged POI following OAS

Totally laparoscopic total gastrectomy for gastric cancer: Literature review and comparison of the procedure of esophagojejunostomy
There has been a recent increase in the use of totally laparoscopic total gastrectomy (TLTG) for gastric cancer. However, there is no scientific evidence to determine which esophagojejunostomy (EJS) technique is the best. In addition, both short- and long-term oncological results of TLTG are inconsistent. We reviewed 25 articles about TLTG for gastric cancer in which at least 10 cases were included. We analyzed the short-term results, relationships between EJS techniques and complications, long-term oncological results, and comparative study results of TLTG. TLTG was performed in a total of 1170 patients. The mortality rate was 0.7%, and the short-term results were satisfactory. Regarding EJS techniques and complications, circular staplers (CSs) methods were significantly associated with leakage (4.7% vs. 1.1%, p < 0.001) and stenosis (8.3% vs. 1.8%, p < 0.001) of the EJS as compared with the linear stapler method. The long-term oncological prognosis was acceptable in patients with early gastric cancers and without metastases to lymph nodes. Although TLTG tended to increase surgical time compared with open total gastrectomy and laparoscopy-assisted total gastrectomy, it reduced intraoperative blood loss and was expected to shorten postoperative hospital stay. TLTG is found to be safer and more feasible than open total gastrectomy and laparoscopy-assisted total gastrectomy. At present, there is no evidence to encourage performing TLTG for patients with advanced gastric cancer from the viewpoint of long-term oncological prognosis. Although the current major EJS techniques are CS and linear stapler methods, in this review, CS methods are significantly associated with leakage and stenosis of the EJS
Design of PG-Surfactants Bearing Polyacrylamide Polymer Chain to Solubilize Membrane Proteins in a Surfactant-Free Buffer
The development of techniques capable of using membrane proteins in a surfactant-free aqueous buffer is an attractive research area, and it should be elucidated for various membrane protein studies. To this end, we examined a method using new solubilization surfactants that do not detach from membrane protein surfaces once bound. The designed solubilization surfactants, DKDKC12K-PAn (n = 5, 7, and 18), consist of two parts: one is the lipopeptide-based solubilization surfactant part, DKDKC12K, fand the other is the covalently connected linear polyacrylamide (PA) chain with different Mw values of 5, 7, or 18 kDa. Intermolecular interactions between the PA chains in DKDKC12K-PAn concentrated on the surfaces of membrane proteins via amphiphilic binding of the DKDKC12K part to the integral membrane domain was observed. Therefore, DKDKC12K-PAn (n = 5, 7, and 18) could maintain a bound state even after removal of the unbound by ultrafiltration or gel-filtration chromatography. We used photosystem I (PSI) from Thermosynecoccus vulcanus as a representative to assess the impacts of new surfactants on the solubilized membrane protein structure and functions. Based on the maintenance of unique photophysical properties of PSI, we evaluated the ability of DKDKC12K-PAn (n = 5, 7, and 18) as a new solubilization surfactant
