[Two Cases of Blind Pouch Syndrome after Total Gastrectomy].

Blind loop syndrome(BLS)is one of the complications that can occur after intestinal anastomosis. Patients with the syndrome present with various clinical features, including nutrient malabsorption caused by the blind end as a result of the anastomotic morphology. On the other hand, blind pouch syndrome(BPS)is a subtype of BLS.

Prognostic impacts of categorized postoperative complications in surgery for gastric cancer.

Background: Postoperative complications generally aggravate postoperative prognosis and are correlated with both cancer-specific death and death from other causes.

Methods: Subjects were 197 patients who underwent gastrectomy at Kyoto Chubu Medical Center. Cancer-specific survival (CSS) and non-CSS (NCSS) were compared between cases with and without complications.

[A Case of R0 Resection, with Preservation of Bladder Function, of Advanced Rectal Cancer Infiltrating the Bladder with a Single Metastatic Liver Tumor Due to Preoperative Chemotherapy].

A 75-year-old man was diagnosed with advanced rectal cancer infiltrating the bladder and a single metastatic liver tumor. The patient first underwent colostomy followed by 8 cycles of chemotherapy, using a regimen of cetuximab, calcium levofolinate hydrate, fluorouracil and oxaliplatin(Cmab plus mFOLFOX6). This treatment resulted in a partial response(PR).

[Impact of the Age-Adjusted Charlson Comorbidity Index on Postoperative Complications after Gastric Cancer Surgery].

Background: The primary objective of this retrospective study was to examine the association between the age-adjusted Charlson comorbidity index(aCCI)score and postoperative complications after gastric cancer surgery.

Method: A total of 237 patients who underwent distal/total gastrectomy for gastric cancer between 2012 and 2020 were enrolled in this study. The aCCI and CCI were calculated by weighting individual comorbidities.

Impact of Preoperative Nutritional Indicator on Poor Postoperative Outcomes in Geriatric Patients with Colorectal Cancer.

The present study aimed to analyze the association between preoperative nutritional assessment and poor postoperative outcomes in geriatric patients with colorectal cancer. This retrospective study included 138 patients aged ≥80 years with colorectal cancer who underwent surgery from January 2013 to December 2018. Patients were classified into two groups according to outcomes, poor group and normal group.

[Comparison between Overall Survival and Disease-Specific Survival after Surgery in Gastric Cancer].

Background: It has been reported that we should give consideration to death caused by other disease from comparison between overall survival(OS)and disease specific survival(DSS)in several studies.

Patients And Methods: Relationships between the clinicopathological features of OS and DSS were examined among 197 patients undergoing surgery for gastric cancer.

Results: In OS analysis, the Charlson comorbidity index(CCI), pathological T and postoperative complications with Clavien-Dindo Grade≥Ⅲ were associated significantly in multivariate analyses(p=0.

[Impact of Preoperative Comorbidities on Long-Term Prognosis in Elderly Patients with Gastric and Colorectal Cancer].

Background: There has been an increase in the number of elderly cancer patients with preoperative comorbidities, which decrease the safety of surgical therapy. Assessment of comorbidities is useful for prediction of the outcome of treatment in these patients.

Patients And Methods: The Charlson comorbidity index(CCI)was determined in 83 elderly patients undergo- ing surgery for gastric and colorectal cancer.

Is pneumoperitoneum necessary for single-incision laparoscopy-assisted appendectomy for pediatric appendicitis?

Introduction: Several studies have reported the treatment of pediatric appendicitis with single-incision laparoscopy-assisted appendectomy using a muscle hook without pneumoperitoneum to lift the abdominal wall. However, very few studies have investigated the advantages of this procedure. We examined the utility of this procedure in our department.

Early Neuropathy Related to Oxaliplatin Treatment in Advanced and Recurrent Colorectal Cancer.

Background/aim: Chemotherapy dose adjustments in colorectal cancer are usually based on body surface area (BSA). The goal of this study was to investigate patients with nutritional disorder who developed early peripheral neuropathy due to inappropriate dose adjustment of oxaliplatin.

Patients And Methods: The study subjects were 88 patients with advanced or recurrent colorectal cancer who underwent chemotherapy with oxaliplatin.

[A Study of 15 Patients with Colorectal Cancer Perforation, Kyoto Chubu Medical Center].

In colorectal cancer perforation, selecting the appropriate surgical operation while considering the patient's life and radical treatment is important. We divided 15 patients who underwent surgical intervention at our department into 2 groups, namely, free and covering perforation groups, and conducted a retrospective analysis. In the comparison between the 2 groups (free vs covering), there were 11 vs 4 cases with similar morphology, 2 vs 0 cases of perioperative death, and 3 vs 0 cases of recurrence, respectively.

[A Case of Cancerous Meningitis in Juvenile Onset Gastric Cancer].

A 30-year-old woman was diagnosed with advanced gastric cancer(MUL, Circ, Type 4, por1+2, T4a, N3a, M1[LYM, P1, CY1, H0], Stage Ⅳ)on delivery. Because of unresectable, she underwent chemotherapy(first-line: S-1 plus CDDP, secondline: PTX plus Rmab, and third-line: Nmab); approximately 10 months later, she started complaining of headache. We performed a close examination, because she also developed resistance to chemotherapy.

[A Case of Ischemic Colitis Four Months after Laparoscopic Left Hemicolectomy Preserving Superior Rectal Artery].

The case was for a male at the age of 80. We performed laparoscopic left hemicolectomy and D3 lymph node dissection for descending colon cancer. He had a good postoperative prognosis and was discharged on the 14th day after the operation.
