In recent years, total pancreatectomy has come to be expected good results by the progress of diabetes treatment and the development of pancreatic enzyme agents, it is necessary to carefully judge each case for adaptation.Whether the stomach should be preserved during total pancreatectomy(TP)is controversial. Therefore, we examined the correlation between stomach-preserving procedures on TP and postoperative gastric complications. Seven consecutive cases underwent TP(standard TP 1 case, SSPTP 3 cases, PPTP 3 cases)for pancreatic cancer during the time period 2011-2019 at our hospital. There was no clinical case of postoperative gastric ulcer nor bleeding. Delayed gastric emptying(DGE)was observed in 4 cases of Grade A and 2 cases of Grade C. One of the Grade C cases was considered to be secondary DGE due to postoperative intestinal necrosis. The other was SSPTP case whose left gastric artery(LGA)was ligated. Sunitinib mouse The patient had difficulty of food intake after the surgery and gastrointestinal endoscopy showed widespread hemorrhage and erosion of the gastric mucosa, considered to be ischemic gastropathy. Regarding primary DGE, most of cases were within Grade A even in stomach-preserving cases. Whereas, stomach-preserving procedure should be avoided when the LGA is ligated, because ischemic gastropathy may occur.Generally, the first treatment plan for anal canal squamous cell carcinoma(SCC)is chemo-radiation therapy(CRT). We experienced an extremely rare surgery case of anal canal SCC after prostate brachytherapy. A man in his 70s who had undergone brachytherapy for prostate cancer 8 years before visited our hospital because of blood in feces. A tumor prolapsed from the anal verge, and biopsy revealed SCC. Contrast-enhanced computed tomography showed front-wall thickness in the lower rectum, but we could not evaluate it in detail because of the halation by brachytherapy seeds. We performed laparoscopic abdominoperineal resection to avoid an overdose of radiation for the rectum. Pathological staging was pT2N1aM0, pStage ⅢA. These findings might suggest radiation-induced cancer after brachytherapy.We report a case of a male in his sixties with appendiceal cancer who underwent radical resection following CAPOX plus bevacizumab neoadjuvant chemotherapy. The patient presented to our hospital with a chief complaint of chronic low abdominal pain. Contrast-enhanced CT before neoadjuvant chemotherapy revealed an inhomogeneous tumor in the ileocecal region. Invasion to the bladder and the sigmoid colon was also observed. A colonoscopy showed an elevated lesion, which was caused by extramural invasion to the sigmoid colon. Pathological examination of the sigmoid colon tumor revealed well differentiated tubular adenocarcinoma and KRAS codon13 G13D. Hence, we diagnosed the patient with locally advanced appendiceal cancer with invasion to the bladder and sigmoid colon. We administered CAPOX plus bevacizumab as neoadjuvant chemotherapy. Contrast-enhanced abdominal CT after neoadjuvant chemotherapy revealed shrinkage of the primary tumor and reduction in the invasion to the bladder and sigmoid colon. We performed ileocecal resection(+D3), a partial sigmoidectomy, and partial bladder resection on the 135th day from the diagnosis. The resected specimen showed an appendiceal tumor with invasion to the bladder and sigmoid colon. The pathological diagnosis was Ⅴ, yType 5, tub2>tub1, ypT4b, ypN0, ycH0, ycM0, ycPUL0, Ly1b, V1b(VB), Pn01b, pStage Ⅱa, and the histological treatment effect of preoperative therapy was Grade 1b. Our experience indicates that in patients with locally advanced appendiceal cancer, multimodal treatment with neoadjuvant chemotherapy is an effective option.The patient was a 63-year-old male. The upper esophagogastroduodenoscopy for anemia found a type 2 tumor at the greater curvature of the gastric angular region, which was revealed as a low-differentiated adenocarcinoma by biopsy. The abdominal CT showed a total of 10 metastases of 11-27 mm in size at the bilateral hepatic lobes. T3(SS)N0M1H1P0 and cStage Ⅳ of gastric cancer was diagnosed. SP therapy was performed for 1 year the size of gastric primary focus reduced, and a metastatic lesion of 7 mm in size was found only at S1. We performed a gastrectomy of the pylorus side and hepatic S1 radiofrequency ablation. Postoperatively, S-1 single therapy has continued, and the patient has survived to date for 2 years without any recurrence. Although the prognosis of a simultaneous multiple liver metastasis from gastric cancer tends to be poor, our multidisciplinary approach resulted in a favorable prognosis.To clarify the pudendal motor nerve(PMN)play in preventing fecal incontinence(FI)after low anterior resection(LAR) for lower rectal cancer, the PMN function was studied at early postoperative period after LAR. A total of 30 patients aged 43 to 78 years (21 men and 9 women with a mean age of 62.4 years) who underwent LAR for LRC were enrolled in the present study. Based on postoperative FI, these patients were divided into 2 groups(group A patients with FI[n=10], group B patients without FI[continence, n=20]). These were compared with group C(n=28, control subjects, 18 men and 10 women aged 46 to 76 years with a mean age of 60.2 years). Magnetic stimulation at the S2-4 sacral levels has been shown to activate the PMN root of the cauda equina. PMN latency(PMNL)at posterior sides of the anal canal was studied. FI after LAR was also evaluated by the Wexner score(WS). All patients were pathological Stage Ⅰ(20 patients T1, N0, M0; 10 patients T2, N0, M0). Group A had a significantly larger proportion of men than group B(p less then 0.05). The distance of anastomosis from anal verge(DAAV)in group A(2.4±1.7 cm)was significantly shorter than in group B(4.4±0.9 cm)(p less then 0.001). WS from 8 to 10(mean 9.25)comprised 20.0% of group A, 11 to 15(mean 13.5)50.0%, and 16 to 20(mean 18.5)comprised 30.0%. All patients in group A(WS 8 or more)were incontinent. In contrast, all patients in group B(WS 0)and C(WS 0)were continent. Patients in pre-operative defecation(WS 0)were also continent. As for PMNL, the conduction delay in group A(7.9±0.9 ms)was significantly longer than in groups B(4.1±0.6 ms)and C(3.9±0.3 ms) (p less then 0.001, respectively). FI after LAR with a short DAAV may be EAS dysfunction due to damage of PMN.
