ABSTRACT
Aim: To investigate the risk factors for postoperative delirium among elderly patients undergoing elective surgery for gastroenterological cancer. Methods: From May 2020 to March 2022, patients ≥75 years old with gastroenterological cancer who underwent radical surgery were enrolled. The geriatric assessment, including evaluations of frailty, physical function, nutrition status, and cognitive function, was conducted preoperatively. The confusion assessment method was used to diagnose postoperative delirium. A multivariate logistic regression analysis was used to determine risk factors for postoperative delirium. Results: A total of 158 patients were eligible for inclusion in this study. Of these 53 patients (34%) developed postoperative delirium. In the univariate analysis, the age, regular use of sleeping drugs and benzodiazepine, Charlson Comorbidity Index score, performance status, Fried's frailty score, Vulnerable Elders Survey-13 score, grip weakness, Short Physical Performance Battery (SPPB) score, Mini Nutritional Assessment Short-Form score, and Mini-Mental State Examination score were statistically associated with the incidence of postoperative delirium. In the multivariate analysis, a SPPB score ≤9, Mini Nutritional Assessment score ≤11, a Mini-Mental State Examination score ≤24, and regular use of benzodiazepine were found to be independent preoperative risk factors for postoperative delirium. Conclusion: Certain findings during the preoperative geriatric assessment, especially low SPPB, Mini Nutritional Assessment Short-Form and Mini-Mental State Examination scores, and regular use of benzodiazepine were risk factors for postoperative delirium in elderly patients undergoing gastroenterological surgery.
ABSTRACT
BACKGROUND: Hepatic pseudoaneurysm (HPA) is a rare complication that can occur after liver trauma and carries a high risk of rupture. HPA is usually asymptomatic until rupture, so performing routine surveillance of liver trauma patients is important. Most posttraumatic HPA occurs within the first week after injury, so surveillance imaging ~ 7 days postinjury is suggested. CASE PRESENTATION: We herein report a 47-year-old man who was diagnosed with asymptomatic HPA 25 days after a knife injury. The patient was transferred to the emergency room after attempting suicide by stabbing himself in his abdomen with a knife. The knife was surgically removed, and the postoperative course was uneventful. Computed tomography (CT) on postoperative day (POD) 12 showed no HPA. However, follow-up CT on POD 25 revealed HPA. The HPA was treated with coil embolization. The patient was discharged with no complications. One year after the injury, the patient had no recurrence or medical problems. CONCLUSION: When managing patients with penetrating liver trauma, it is important to note that HPA may not be identifiable on CT early after injury but may still develop later.
ABSTRACT
BACKGROUND: Muir-Torre syndrome is an autosomal-dominant mutation in mismatch repair genes that gives rise to sebaceous tumors and visceral malignancies over time. Because colorectal and genitourinary cancers are common in Muir-Torre syndrome, duodenal carcinoma diagnoses are often delayed. CASE PRESENTATION: A 58-year-old woman presented with severe emaciation, anorexia, and upper abdominal pain. She had a history of rectal carcinoma, ascending colon carcinoma, and a right shoulder sebaceous carcinoma. Upper gastrointestinal endoscopy and computed tomography examinations suggested duodenal obstruction due to superior mesenteric artery syndrome, leading to long-term observation. Seven months later, she was finally diagnosed with duodenal carcinoma of the third portion. As the papilla of Vater was preservable due to tumor location, she received a partial duodenectomy in lieu of a pancreatoduodenectomy. Pathologically, the tumor was a well-differentiated adenocarcinoma with a classification of T3N0M0 Stage IIA (UICC, 8th edition). The postoperative course was uneventful and her appetite returned. A mutation in mismatch repair gene MSH2 confirmed the diagnosis of Muir-Torre syndrome genetically. Three years later, her nutritional status has fully recovered and she is free from both recurrence and metastasis. CONCLUSION: In patients with comorbid skin sebaceous tumors and gastrointestinal malignancies, genetic screening is strongly recommended. Patients with Muir-Torre syndrome require long-term follow-up, and function-preserving treatment is desirable.
ABSTRACT
BACKGROUND: A gastrocolic fistula is an unusual communication between the colon and the stomach. Although colon cancer is the most common malignant cause of gastrocolic fistula in the Western world, the incidence of gastrocolic fistula due to colon cancer is 0.3% in operated cases. CASE PRESENTATION: A 68-year-old man presented with anorexia, general malaise, weight loss, and vomiting of fecal matter. Investigations revealed that the patient had a large nonmetastatic splenic flexure tumor that was diagnosed as colon cancer and had invaded the stomach and pancreas. An upper gastrointestinal series confirmed a gastrocolic fistula. Left hemicolectomy, distal gastrectomy, distal pancreatectomy, and splenectomy were performed. Histology revealed transverse colon cancer, which was UICC stage (8th edition) pT4bN1bcM0 pStage IIIC. Adjuvant chemotherapy was not performed. There was no recurrence or metastasis one year after surgery. We reviewed 17 cases including our case of a gastrocolic fistula caused by colon cancer. Neoadjuvant chemotherapy was not given to any of the patients, and en bloc resections were conducted in all cases. Adjuvant chemotherapy was given to almost all of the patients. There was no recurrence or metastasis. CONCLUSIONS: For gastrocolic fistula caused by advanced colon cancer, secure en bloc surgical resection was the initial treatment in all 17 reported cases including the present case, and adjuvant chemotherapy may contribute to a better prognosis.
ABSTRACT
INTRODUCTION AND IMPORTANCE: Well-leg compartment syndrome (WLCS) develops from abnormal positioning of the limb during surgery. There have been few reports of WLCS in rectal cancer patients, although the lithotomy position, which is widely applied for rectal surgery, is a risk factor for WLCS. CASE PRESENTATION: A 56-year-old man with rectal cancer underwent laparoscopic low anterior resection of the rectum, left lateral lymph node dissection and diverting ileostomy. The operation time was 393 min. The patient was in the head-down tilt lithotomy position and rotated to the right side. Postoperatively, he complained of left lower leg pain and swelling and difficulty moving his legs. The compartment pressure of his right and left lower legs was 80 mmHg and 120 mmHg, respectively. A diagnosis of bilateral WLCS was made, and fasciotomy of both lower legs was performed 2 h after surgery. Although he was able to live his daily life, mild numbness remained in his toes one year after surgery. CLINICAL DISCUSSION: In addition to risk factors previously reported for WLCS, our review shows that the male sex and left side are associated with a greater risk of WLCS, especially in rectal surgery. Additionally, our review reveals that the type of rectal surgery leading to WLCS is almost always laparoscopic surgery. CONCLUSION: Surgeons should be especially vigilant for WLCS when they encounter patients, especially males, who complain of left lower leg pain after laparoscopic rectal surgery.
