RESUMEN
PURPOSE: This study aimed to investigate the presence of schistocytes in patients with sepsis and its association with mortality and organ failure. METHODS: We conducted a retrospective observational study at Shiga University of Medical Science Hospital, Japan, from January 2015 to April 2021. This study included patients diagnosed with sepsis or septic shock. Schistocytes were identified through daily hematological examinations. Moreover, data on mortality rates and organ failure based on sequential organ failure assessment (SOFA) scores were systematically collected and analyzed. RESULTS: Schistocytes were detected in 41 of the 330 patients with sepsis. The presence of schistocytes was associated with significantly high 90-day and 1-year mortality rates (48.7% and 68.2%, respectively; p < 0.001). Patients with schistocytes exhibited higher SOFA scores, particularly in the coagulation and renal components, indicating more severe organ failure than that observed in patients without schistocytes. These findings persisted even after adjusting for confounding factors, such as age, sex, and baseline comorbidities. Additionally, we observed that patients with schistocytes required frequent red blood cells, further highlighting the severity of their conditions. CONCLUSION: Schistocytes are significantly associated with increased long-term mortality and organ failure in patients with sepsis. Their detection may provide crucial insights into disease severity, guide targeted therapeutic strategies, and potentially improve the long-term outcomes of sepsis management.
RESUMEN
Vasovagal reactions are the most common type of adverse reaction after blood donation; however, there are no reports of ischemic colitis as an adverse reaction after blood donation. A previously healthy 55-year-old woman suffered loss of consciousness at the end of her first plasma donation. She was diagnosed with a vasovagal reaction and received hydration. However, she developed persistent left flank pain and watery diarrhea, followed by bloody diarrhea. Abdominal computed tomography confirmed ischemic colitis. She was asked to fast and was eventually discharged 7 days later. We should consider the possibility of ischemic colitis if patients develop persistent abdominal pain after transient hypotension, such as that observed during a vasovagal reaction.

A 50-year-old man presented with epigastric pain after eating raw mackerel. Abdominal computed tomography revealed submucosal edema of the gastric antrum and pelvic ileum. Gastroscopy revealed an Anisakis simplex in the gastric antrum. His epigastric pain resolved after endoscopic removal of the Anisakis; however, he developed right lower quadrant pain the following day. Abdominal computed tomography showed submucosal edema of the terminal ileum involving different ileal loops, which was not present on admission. The patient developed delayed intestinal anisakiasis. A serving of raw fish may contain more than one Anisakis. After gastric anisakiasis, a second Anisakis may cause intestinal anisakiasis.
RESUMEN
A 90-year-old female patient was admitted to our hospital with a chief complaint of vomiting.Gastroscopy revealed type 3 gastric cancer and gastric outlet obstruction(GOO).Abdominal computed tomography revealed thickening of the antral wall and suggested the presence of 3 perigastric lymph node metastases, but there was no ascitic fluid or distant metastasis.The clinical diagnosis was T4a(SE)N2H0CYXP0M0, Stage III B, according to the Japanese Classification of Gastric Carcinoma.Her general conditions including kidney and cardiac function were good, we considered that she was able to tolerate radical distal gastrectomy.We planned laparoscopic distal gastrectomy(LDG)and D2 lymphadenectomy after getting sufficient informed consent.The patient experienced an uneventful post-operative recovery, and was discharged in good health 11 days after surgery.

A 69-year-old man with right upper quadrant abdominal pain and fever was referred to our hospital. He had a history of asbestosis exposure. Computed tomography(CT)revealed a mass at the right subhepatic space, and an antibiotic was administered after a diagnosis of an abdominal abscess. However, the patient did not respond to the treatment, and finally, exploratory laparoscopy was performed. A sheet of combined white nodules surrounding the right lobe of the liver was found, and the mass was continuous with the covering particles. Biopsy of the mass and immunohistochemical examination was performed. The resulting diagnosis was diffuse epithelial malignant peritoneal mesothelioma(MPM). Postoperative systematic chemotherapy of pemetrexed and cisplatin was administered. Laparoscopy was useful to evaluate the distribution of the MPM, which led to adequate therapeutic determination.

An 86-year-old man was brought in ambulance to our hospital because of sudden hematochezia and abdominal pain during defecation. Intestinal prolapse approximately 80mm from the anus and a type 1 tumor 50mm in size on the mucosal surface were detected. The intestinal prolapse was manually repositioned, and the reduction of the intussusception was confirmed by computed tomography (CT). Following colonoscopy and abdominal-enhanced CT, a sigmoid colon cancer without distant metastases was detected. Elective laparoscopic radical surgery was performed. The present study described a rare case of sigmoid colon cancer with an intussusception prolapsing through the anus and highlighted the treatment strategy by reviewing 48 previous cases. The treatment strategy employed was as follows:first, manual repositioning of the intestinal prolapse was attempted;and second, the presence of intussusception was confirmed by CT. In cases when repositioning of the intussusception was not possible, even with the use of an endoscope or contrast enema, emergency surgery was required.

A 58-year-old man underwent rectal resection(D2 dissection)for rectal cancer and liver/lung metastases in August 2009. Histopathological findings were Ra, type 2, 70×80mm, tub1>tub2, int, pSI(peritoneum), INF b, ly1, v1, pN1(2/13), pPM0, pDM0, M1a(H1, PUL1), fStage IV . The lung metastasis had disappeared on chest CT after postoperative chemotherapy and we were able to perform radical resection of the liver metastasis by performing hepatectomy twice. In October 2013, anal pain appeared and a painful tumor approximately 2 cm in size was found in the 5 o'clock direction of the anus. Biopsy revealed a well-differentiated tubular adenocarcinoma similar to rectal cancer, and it was diagnosed as a fistula metastasis of rectal cancer.We performed chemoradiotherapy(S-1 120mg/day plus RT 60 Gy/30 Fr)as surgery was recommended but refused. As a result, the tumor reduced markedly in size. In December 2015, the tumor enlarged in size and the patient and family requested surgery. We, therefore, performed abdominoperineal resection. Currently, the patient is alive at 18 months after surgery with no recurrence.

A spontaneous external biliary fistula is most commonly a cholecystocutaneous fistula secondary to acute cholecystitis. A fistula arising from an intrahepatic duct is extremely rare. An 87-year-old man presented with swelling of the epigastric region and right upper quadrant abdomen. He had a history of cholecystectomy and endoscopic sphincterotomy. After antibiotic treatment and surgical opening of both lesions, abdominal computed tomography demonstrated a soft tissue mass cephalad to the umbilicus. We excised the mass, and found it to be associated with a fistula through the linea alba. Fistulography showed an abscess cavity communicating with the intrahepatic duct in segment III. Histopathological examination of the mass showed an abscess without malignancy. The fistula closed spontaneously without laparotomy. In this case, the underlying pathology was considered to be associated with a subcapsular hepatic cyst in segment III.

A 73-year-old man was admitted with sigmoid colon diverticulitis. Although a biopsy did not indicate malignancy, the sigmoid colon was completely obstructed following conservative treatment. After sigmoidectomy, the histopathological findings revealed a well-differentiated adenocarcinoma localized to the mucosal surface; invasive micropapillary carcinoma (IMPC)accounting for>95% of the tumor volume spread extensively below the submucosal layer. IMPC is highly malignant and difficult to diagnose preoperatively, possibly due to the presence of poorly differentiated histological sub-types in the deepest portions of the tumor.

Aim: Bladder ruptures are commonly misdiagnosed as gastrointestinal perforations or intestinal ischemia. If a diagnosis is made preoperatively, conservative treatment is a safe and effective option. We evaluated the validity of using the attenuation value of ascites, measured by non-contrast computed tomography (CT), to identify patients with bladder ruptures. Methods: A retrospective search of our hospital database identified 7 patients with confirmed bladder ruptures between 2007 and 2013. We also enrolled 18 patients with gastrointestinal perforations and 10 patients with intestinal ischemia with detectable ascites on abdominal CT that had undergone emergency exploratory laparotomy between 2007 and 2013. Between-group comparisons of attenuation values of ascites as obtained by non-contrast CT were evaluated. Results: All attenuation values were less than 10 Hounsfield units (HU) in bladder rupture patients. Moreover, the attenuation value of ascites in cases of bladder rupture (median, 5.7; range, 3.1-6.1) was significantly lower than in cases of gastrointestinal perforation (median, 14.7; range, 4.7-25.4) and intestinal ischemia (median, 13.3; range, 6.0-18.1) (P = 0.004 for both comparisons). Conclusion: Bladder rupture mimics gastrointestinal perforation and intestinal ischemia with acute kidney injury. Therefore, the diagnosis of bladder rupture using the attenuation value of ascites on non-contrast CT is both useful and highly significant. We suggest that bladder rupture be considered in the differential diagnosis of patients presenting with acute abdominal pain and attenuation values of ascites of less than 10 Hounsfield units.
RESUMEN
Neuroleptic malignant syndrome (NMS) with characteristic symptoms is a potentially lethal reaction to antipsychotic drugs. Atypical NMS usually lacks major symptoms and frequently occurs after treatment using atypical antipsychotics, such as aripiprazole. A 64-year-old man developed aripiprazole-induced NMS after surgery, and our early recognition of the NMS was based on high creatine kinase levels and low serum iron levels. His characteristic symptoms (a fever, rigidity, and altered mental status) were only present for a few hours and were resolved by aripiprazole discontinuation and supportive care. Aripiprazole-induced NMS can present with brief but major symptoms, and clinicians may overlook this "brief" appearance of NMS.

BACKGROUND: No report has described the predictive factor of surgical difficulty for laparoscopic cholecystectomy (LC) by preoperative computed tomography (CT) findings. This study aimed to investigate whether dynamic CT findings can predict the difficulty of LC for acute cholecystitis. MATERIALS AND METHODS: Fifty-seven patients who underwent emergency LC and dynamic CT preoperatively were enrolled. Difficult LC (DLC) was defined as any patient with an operative time ≥3 h, bleeding volume ≥300 mL, common bile duct injury, partial cholecystectomy, the need for a second surgeon, and/or conversion to open surgery. Patients were assigned to either the DLC (+) or DLC (-) group. We determined the CT attenuation ratio of the arterial phase (ARAP) to represent the degree of transient focal enhancement of the liver adjacent to the gallbladder. The ARAP cutoff value for a DLC predictor was determined using receiver operating characteristic curve analysis. Patients' characteristics and CT findings, including the ARAP, were compared between the groups. The Fisher exact test for categorical variables and the Mann-Whitney U test for continuous variables with Bonferroni correction were used to evaluate the significance of differences. RESULTS: Fifteen patients were assigned to the DLC (+) group. The ARAP was significantly higher in the DLC (+) group than in the DLC (-) group (P = 0.006). The ARAP cutoff value was 1.55. Regarding the CT findings, an ARAP ≥1.55 (P = 0.005) was significantly correlated with DLC. CONCLUSIONS: Among dynamic CT findings, an increased ARAP is a predictive factor for DLC.

The patient was a 64-year-old man with esophagogastric junction cancer. We performed right thoracotomy-laparotomy for lower esophageal and cardiac gastric resection, D2 lymphadenectomy, and reconstruction of a gastric tube in October 2011. Histopathology confirmed T4aN1M1(LYM), Stage IV cancer(Japanese Classification of Gastric Carcinoma, 14th edition) with R0 resection. Because of preexisting alcoholic cirrhosis, postoperative chemotherapy was not an option. In March 2014, we performed left adrenalectomy for left adrenal metastasis, and in December 2014, we performed right adrenalectomy for metastasis to the right adrenal gland. The patient was prescribed 20mg/day of hydrocortisone postoperatively. Survival from the right adrenalectomy was 2 years and 2 months, and survival from the first operation was 5 years and 4 months, without recurrence. This case of esophagogastric junction cancer resection with bilateral adrenal metastasis is rare, with only one previously reported case in Japan.

An 80-year-old man who had undergone distal gastrectomy and Billroth-II gastrojejunostomy 38 years previously, for a benign gastric ulcer, was diagnosed with remnant gastric cancer based on upper gastrointestinal endoscopy findings. He presented at our emergency department with acute-onset epigastric pain due to perforated remnant gastric cancer. Conservative medical management was selected, including nasogastric tube insertion, antibiotics, and proton pump inhibitors, because his peritonitis was limited to his epigastrium and his general condition was stable. Twenty-one days after the perforation occurred, curative total remnant gastrectomy and D2 lymphadenectomy were performed. Adhesion between the lateral segment of the liver and the dissected lesser curvature of the gastric remnant may have contributed to the peritonitis in this case, which was limited to the epigastrium. This is the first report of perforated remnant gastric cancer in which conservative treatment was effective prior to curative resection. The protocol reported here may be of use to other clinicians who may encounter this clinical entity in their practices.
RESUMEN
OBJECTIVE: To determine if the increase in transient focal enhancement of the liver adjacent to the gallbladder seen on dynamic computed tomography (CT) is greater in gangrenous cholecystitis than in nongangrenous cholecystitis by determining the CT attenuation value. METHODS: We retrospectively reviewed the medical records of 57 patients who underwent emergency cholecystectomy for acute cholecystitis and preoperative dynamic CT scans between March 2011 and April 2016. Based on the pathology findings, patients were assigned to a gangrenous group or a nongangrenous group. The CT attenuation ratio (AR) was defined as the ratio of the maximum CT attenuation value in the region of interest in segment 5 (liver parenchyma adjacent to the gallbladder) and that in the control region of interest in segment 8. The patient characteristics and CT findings were compared between the groups. The appropriate AR of the arterial phase (ARAP) cutoff value for a diagnosis of gangrenous cholecystitis was determined using receiver operating characteristic curve analysis. RESULTS: The ARAP was significantly higher in the gangrenous group than in the nongangrenous group (P < .001); the area under the receiver operating characteristic curve was 0.849. The ARAP cutoff value of 1.46 had a sensitivity and specificity of 84.6% and 83.9%, respectively (odds ratio, 21.17; 95% confidence interval, 4.90-118.91), and ARAP ≥1.46 was significantly correlated with a diagnosis of gangrenous cholecystitis (P < .001). CONCLUSIONS: The increase in transient focal enhancement of the liver adjacent to the gallbladder during the arterial phase of dynamic CT was greater in gangrenous cholecystitis than in nongangrenous cholecystitis.

A 49-year-old man visited our hospital with a chief complaint of abdominal pain that began 1 day before his visit.An approximately 30 cm tumor that was extensively in contact with the gastric wall in the abdominal cavity was detected on computed tomography(CT).An elevated lesion covered with normal mucosa on the posterior wall of the greater curvature was detected on upper endoscopy.He was diagnosed with a submucosal tumor of the stomach, and he underwent surgery. Surgical findings revealed an elastic soft tumor with a maximal dimension of 38 cm that projected from the posterior wall of the stomach beyond the gastric wall.No invasion and metastasis to other organs were detected.Partial gastrectomy was performed.On histopathological examination, proliferation of atypical round and spindle cells was found, and immunostaining was negative for KIT but positive for CD34.In the gene search, an Asp842Val mutation was detected in exon 18 of the PDGFRA gene.Currently, the patient has survived for 7 months after surgery without recurrence.

Case: An 88-year-old woman presented with abdominal pain, massive ascites, and acute kidney injury. She was clinically hypervolemic and the computed tomography attenuation value of the ascites was near that of water. Subsequent abdominocentesis revealed ammonia-smelling ascites fluid, leading to a suspicion of urinary tract injury, and a conclusive diagnosis of spontaneous bladder rupture was achieved using cystography. Outcome: The patient was managed conservatively with antibiotics, percutaneous drainage, and bladder catheter. As a result, she was discharged with normal renal function. Conclusion: The diagnosis of bladder rupture is difficult, and is rarely confirmed in the absence of a diagnostic suspicion. This case indicates that ascitic fluid odor, patient volume status, and the computed tomography attenuation value of ascites are potential indicators of bladder rupture.
