Acute abdominal pain due to sigmoid volvulus with persistent descending mesocolon: a case report.

BACKGROUND: Persistent descending mesocolon, an anomaly of fixation of the mesentery of the descending colon, can sometimes cause complications such as intestinal obstruction and intussusception. We present the first reported case of sigmoid volvulus with persistent descending mesocolon. CASE PRESENTATION: An 82-year-old Japanese man had intermittent lower abdominal pain. Abdominal computed tomography showed dilation and a shift to the right side of the sigmoid colon, but no findings of volvulus. The next day, he presented continuous lower abdominal pain with bloody stool. A second abdominal computed tomography showed strangulation and dilation of the sigmoid colon, with shift from the right side of the abdominal cavity to the pelvic space. This suggested the descending colon was running to the medial side with sigmoid volvulus. Emergency surgery was performed for volvulus with persistent descending mesocolon. Operative findings revealed dilation of the sigmoid colon with a partial poorly colored region and strangulation that caused volvulus. After releasing the strangulation of the sigmoid colon, the descending colon was revealed to be running more to the medial side, with adherence to small intestinal mesentery. There was no Toldt's fusion fascia at the descending colon. Persistent descending mesocolon was therefore diagnosed due to abnormality of fixation of the descending colon. The sigmoid colon, including the poorly colored region, was resected and reconstructed, while the inferior mesenteric and left colonic arteries were preserved because of the complexity of the vascular system running around the descending and sigmoid colon due to the shortened mesentery. These findings were pathologically compatible with circulatory compromise and intestinal degeneration due to sigmoid volvulus. The patient had no complications after discharge, including in relation to defecation. CONCLUSION: Persistent descending mesocolon can occasionally cause acute abdominal symptoms requiring immediate treatment. A computed tomography finding of the descending colon running more to the medial side than ordinary cases can aid diagnosis of persistent descending mesocolon.

Successful procedure with additional omentopexy to suture closure of gallbladder stump in laparoscopic subtotal cholecystectomy.

Laparoscopic subtotal cholecystectomy, a bailout surgery for cholecystitis, can result in postoperative bile leakage, so surgical ingenuity is required. An 88-year-old woman had pain at the right hypochondrium. Abdominal computed tomography showed swelling of the gallbladder and thickness of the gallbladder wall, leading to diagnosis of mild acute cholecystitis. Percutaneous transhepatic gallbladder drainage was performed to alleviate cholecystitis because the patient was taking antiplatelet medicine. Laparoscopic cholecystectomy was then performed within 72 hours from the onset. The gallbladder was operatively found to be strongly fibrotic, so the procedure was switched to laparoscopic subtotal cystectomy, dissecting the gallbladder at the infundibulum-cystic duct level. The gallbladder stump was closed with barbed suture and omentopexy was added due to fragility. There was no significant postoperative bile leakage. Additional omentopexy to stump closure in laparoscopic subtotal cholecystectomy was thought to be useful in prevention of postoperative bile leakage.

Optimal Assessment of Frailty Predicts Postoperative Complications in Older Patients with Colorectal Cancer Surgery.

OBJECTIVES: The increasingly elderly worldwide population has affected the incidence of colorectal cancer. Establishment of reliable assessment of frailty and proposals for multi-disciplinary interventions are urgently required in oncology practices. Kihon Checklist (KCL) was published by the Japanese Ministry of Health, Labor and Welfare originally to identify individuals ≥ 65 years old at probable risk for requiring care or social support. We investigate the validity of KCL for frailty assessment to predict postoperative complication in older patients with colorectal cancer. METHODS: Consecutive colorectal cancer patients aged ≥ 65 (n = 500) were prospectively examined between May 2017 and December 2018. Preoperative frailty assessment was conducted by the G8 questionnaire and KCL. The main outcome measures were correlation between frailty, other clinical variables, and postoperative complications within 30 days after elective surgery. RESULTS: Of the 500 patients, 278 (55.6%) and 164 (32.8%) patients were classified as 'frail' by G8 and KCL, respectively. Overall complications counted among 97 patients (19.4%), and they were significantly associated with KCL ≥ 8-frail (46/164, p = 0.001), as opposed to G8 ≤ 14-frail (56/278, p = 0.531). Multivariate analysis showed that KCL ≥ 8 (hazard ratio 1.88, 95% confidence interval 1.16-3.04, p = 0.011) was an independent risk factor for these complications. CONCLUSIONS: KCL assessment can identify frail older patients likely to suffer from postoperative complications after colorectal cancer surgery. Preoperative screening of frailty, particularly by KCL, would help older patients prevent their worse outcomes in colorectal cancer. TRIAL REGISTRATION: UMIN000026689.

Perineal approach for a gastrointestinal stromal tumor on the anterior wall of the lower rectum.

BACKGROUND: Wide margins of resection and regional lymphadenectomy for GIST are not necessary. Several procedures for rectal GIST have been designed according to the location and size of the tumor to preserve the anal function and decrease the morbidity rate. CASE PRESENTATION: We report a 61-year-old-man with rectal bleeding. Proctologic examination revealed a small mass of approximately 2 cm in diameter on the anterior wall of the rectum at a distance of 4 cm from the anal verge. Histological examination of the biopsy sample via the rectum led to a diagnosis of GIST due to immunohistochemical positivity for C117 and CD34. Perineal resection was planned because abdominoperineal resection with sacrificing the sphincter function was excessive for this small tumor, and low anterior resection with the double stapling technique was difficult due to the lower position. A hemispheric incision was made from one mid-ischial tuberosity to the other with an apex of approximately 2 cm above the anus. The fascia band and muscles were successively transected in order to expose the anterior wall of the rectum, and excision of the tumor was performed. The postoperative course was uneventful, and the patient remained free from incontinence and recurrence. CONCLUSIONS: This perineal approach for a GIST on the anterior wall of the rectum is one option for preserving the anal function and decreasing the morbidity rate.

[Supervised administration of Alzheimer's patients using information communication technology].

Drug adherence is central to the treatment of dementia, which might reduce compliance due to memory loss, particularly among home-based patients with dementia. In order to improve drug adherence, we suggest the efficient and effective supervised administration by use of information communication technology(ICT). ICT makes face-to-face real-time communication possible, and it also enables picture sharing. Therefore, it might be useful to apply ICT to controlling and supervising medication for patients with dementia to improve drug adherence. Accordingly, we enrolled patients who were supposed to take a newly prescribed anti-dementia patch containing the choline esterase inhibitor rivastigmine(Rivastach®)and investigated the effect of ICT-based intervention for drug adherence, emotional change, and cognitive change, utilizing Skype, a free communication software program. Scheduled Skype interventions increased drug adherence ratio, levels of subjective satisfaction, and instrumental activities of daily living(IADL). Furthermore, we can provide patients and their caregivers with a feeling of safety through regular bidirectional communication, as patients can easily consult medical staff regarding the adverse effects of newly prescribed drugs. Instead of frequent visits to their primary physicians, ICT-based communications can be used as a substitute for supervision of medication, given the availability of the telecommunication system. By directly connecting the medical institution to the home, we expect that this ICT-based system will expand into the geriatric care field, including the care of elderly individuals living alone.

[Support for the medication monitoring of patients with alzheimer's dementia by the interactive care system using IT].

In our laboratory, we draw up research aims to improve medication compliance in patients with dementia by video phone, and we have intervened in the cases of 3 patients to date. In this study, we focused on patients who are using a rivastigmine patch for Alzheimer' disease, which can be confirmed by video phone, to examine its efficacy. Specifically, by monitoring the effects of the treatment, skin side effects, of skin and usability for patients and caregivers, we monitor the dosing schedule to prevent interruption of self-medication, with the aim of improving compliance and treatment efficacy. We also consider methods of intervention for increasing the persistence rate of the rivastigmine patch and quality of life(QOL)by using the effectiveness of the video phone to focus on the symptoms of skin side effects. In addition, we examine the interventions that reduce the care burden and anxiety of caregivers by listening during the regular intervention.

Adenocarcinoma arising from heterotopic pancreas in the duodenum.

We present a rare case of adenocarcinoma arising from a heterotopic pancreas in the duodenum, and review the associated literature. A 62-year-old woman was admitted to our hospital, complaining of vomiting and epigastralgia. Imaging studies revealed advanced gastric cancer with a gastric outlet obstruction. Whipple's operation and resection of the regional lymph node were performed because of a direct invasion to the pancreas. Histopathologic examination of the resected specimen demonstrated the malignant transformation of a hetrotopic pancreas in the duodenum. At the 12-month follow-up, there was no recurrence of symptoms. The prognosis of adenocarcinoma arising from a heterotopic pancreas is not known. Further accumulation of cases and investigation of this entity are necessary.

A rare case of xanthogranuloma of the stomach masquerading as an advanced stage tumor.

BACKGROUND: Xanthogranuloma of the stomach is an extremely rare disease, and this lesion has only been found to coexist with early gastric cancer in 2 cases in the literature. CASE PRESENTATION: We report a case of xanthogranuloma of the stomach combined with early gastric cancer that mimicked an advanced stage tumor. A 65-year-old female was referred to our hospital because of epigastralgia. During a physical examination, a defined abdominal mass was palpable in the region of the left hypochondrium. Imaging studies revealed an advanced gastric cancer, which was suspected of having infiltrated the abdominal wall. Total gastrectomy and resection of the regional lymph node and abdominal wall were performed. Histopathologic examination of the resected specimen demonstrated xanthogranuloma combined with early gastric cancer. CONCLUSION: Xanthogranuloma presenting as a form of SMT (submucosal tumor) of the stomach is an extremely rare disease, and diagnosing it preoperatively is difficult. Further accumulation and investigation of this entity is necessary.

The ratio between metastatic and examined lymph nodes is an independent prognostic factor for patients with resectable middle and distal bile duct carcinoma.

BACKGROUND: The lymph node ratio, defined as the ratio between the number of lymph node metastasis and the total number of lymph nodes examined, has been reported to be an important prognostic factor in other gastrointestinal carcinomas except middle and distal bile duct carcinomas. METHODS: Between 1991 and 2004, 62 consecutive patients who underwent surgery for middle and distal bile duct carcinoma were retrospectively analyzed concerning prognostic factors. RESULTS: The median number of lymph nodes examined was 12 (range 5 to 38). The overall 5-year survival rates of patients with lymph node ratio of 0, lymph node ratio of 0 to .2, and lymph node ratio >.2 were 62%, 41%, and 0%, respectively. A multivariate analysis revealed that a lymph node ratio >.2 and perineural invasion were independent predictive factors for survival. CONCLUSIONS: Lymph node ratio >.2 is an important factor to predict survival after resected middle and distal bile duct carcinoma.
