Simplified risk stratification in early cholecystectomy for acute cholecystitis based on age: A report from an institution with zero mortality.

BACKGROUND/PURPOSE: The existing risk stratification for early cholecystectomy in patients with acute cholecystitis (AC) is complex. This study aims to establish a simpler risk assessment for surgical complications after cholecystectomy based on age group. METHODS: This single-center retrospective observational study enrolled 350 patients diagnosed with AC who underwent early cholecystectomy within 72 h of diagnosis from 2013 to 2021. Patients were divided into three subgroups based on age: young (<65 years), elderly (65-79 years), and very elderly (≥80 years). Since no mortality was observed, risk factors for the Clavien-Dindo (CD) grade ≥ II complications were identified within the entire cohort and in each subgroup. RESULTS: There were 120 young, 130 elderly, and 100 very elderly patients. The overall prevalence of complications with CD grade ≥ II was 11.1%. Age and Tokyo Guidelines 18 (TG18) severity were independent risk factors for surgical complications in the whole cohort. Subgroup analysis revealed that there was no independent risk factor in the young group. Meanwhile, age and poor physical status were independent risk factors in the elderly group, and TG18 severity in the very elderly group. CONCLUSION: Evaluation of only age, physical status, and TG18 severity may be sufficient for risk stratification of surgical complications of AC.

Surgeons' involvement in COVID-19 treatment: a practice by a regional core hospital in Japan to avoid physician burnout.

BACKGROUND: To prevent task accumulation on certain divisions, our institution developed a unique system of allocating inpatient treatment of COVID-19 patients to doctors who were not specialized in respiratory infections. The objective of this study was to investigate whether surgeons can be involved in the COVID-19 inpatient treatment without negatively affecting patient outcome, and how such involvement can affect the wellbeing of surgeons. METHODS: There were 300 patients diagnosed with COVID-19 and hospitalized from January to June 2021, and 160 of them were treated by the redeployed doctors. They were divided into 3 groups based on the affiliation of the treating doctor. Patient characteristics and outcomes were compared between the groups. In addition, the impact of COVID-19 duty on participating surgeons was investigated from multiple perspectives, and a postduty survey was conducted. RESULTS: There were 43 patients assigned to the Department of Surgery. There were no differences in the backgrounds and outcomes of patients compared with other groups. The surgeon's overtime hours were significantly longer during the duty period, despite no change in the number of operations and the complication rate. The questionnaire revealed that there was a certain amount of mental and physical burden from the COVID-19 duty. CONCLUSION: Surgeons can take part in inpatient COVID-19 treatment without affecting patient outcome. However, as such duty could negatively affect the surgeons' physical and mental wellbeing, further effort is needed to maintain the balance of fulfilling individual and institutional needs.

Is Palliative Gastrojejunostomy for Malignant Gastric Outlet Obstruction an Optimal Choice for Very Elderly Patients? A Report from a Long-Lived Country.

BACKGROUND: Gastrojejunostomy (GJ) is a surgical option for malignant gastric outlet obstruction (mGOO). Confronting an aging society, the demand to treat elderly cancer patients with unresectable malignancies is increasing; however, the benefit of GJ to the very elderly (≥ 80 years of age) has never been investigated. METHODS: This multicenter, retrospective review included 108 patients who had undergone GJ for mGOO from two medical centers in Japan, one of the most long-lived countries. Patients were divided into two groups, with 80 years of age as the cut-off. Various factors, including surgical complications and patient survival, were compared. RESULTS: GJ in the very elderly (aged ≥ 80 years) was associated with a higher incidence of surgical complications (p = 0.049), such as delayed gastric emptying (DGE; p < 0.001), aspiration pneumonia (p = 0.029), and consequent mortality (p = 0.016). Age ≥80 years was also identified as an independent predictor of DGE (odds ratio 6.444, p = 0.005) and survival after GJ (hazard ratio 7.767, p = 0.016). In particular, the median survival time after GJ in the population aged ≥80 years with gastric cancer was only < 2 months. About the surgical procedure, antiperistaltic anastomosis with partial stomach partitioning (PSP) yielded the lowest occurrence rate of DGE (3.4%) and aspiration pneumonia (1.7%). CONCLUSIONS: GJ does not seem to be the optimal choice for very elderly patients, particularly those with gastric cancer. If performed, antiperistaltic anastomosis with PSP should be employed to reduce the surgical complications.

Enhanced-view totally extraperitoneal repair in a patient with incisional hernia after robot-assisted laparoscopic radical prostatectomy: a case report.

BACKGROUND: Although laparoscopic incisional hernia repair, especially laparoscopic intraperitoneal onlay mesh, is a widely used technique, it can cause serious complications, including mesh erosion, adhesive bowel obstruction, and chronic pain. The enhanced-view totally extraperitoneal (eTEP) technique has been reported to prevent such complications by placing the mesh in the retrorectus space. Here, we report the case of a patient with post-robot-assisted laparoscopic radical prostatectomy (RARP) incisional hernia repaired using the eTEP technique. CASE PRESENTATION: A 67-year-old man, who underwent RARP for prostate cancer 4 years ago developed an incisional hernia. Abdominal computed tomography showed the presence of an epigastric incisional hernia measuring 4 cm long and 3.7 cm wide. We performed an eTEP repair. We closed the hernia defect using a 0 barbed suture and placed a self-gripping mesh measuring 20 cm long and 15 cm wide in the developed retrorectus space with no fixation. There were no postoperative complications, and the patient was discharged on postoperative day 2. CONCLUSIONS: eTEP repair is considered an extremely effective surgical treatment option for incisional hernias because of its few resulting postoperative mesh-and-tacker-related complications.

The safety and feasibility of laparoscopic gastrectomy for gastric cancer in very elderly patients: short-and long-term outcomes.

PURPOSE: It remains unclear whether laparoscopic gastrectomy (LG) for gastric cancer is a suitable treatment for very elderly (VE) patients. We aimed to assess the safety and feasibility of LG for gastric cancer in VE patients. METHODS: We reviewed 226 consecutive patients who underwent LG between January 2010 and December 2016. We compared VE patients (age ≥ 80, n = 38) with non-elderly patients (age ≤ 79, n = 188). RESULTS: An ASA-PS score ≥ 2 was more common in VE group (86.8 vs. 48.9%; P < 0.01). There were no significant differences in the operating time, blood loss, postoperative hospital stay, or postoperative morbidity between the groups. The 3-year survival rate and 3-year disease-specific survival rate were lower in the VE group (53.7 vs. 85.6%; P < 0.0001, 78.5 vs. 92.4%; P = 0.0116). A univariate analysis showed that PS scores ≥ 2, Charlson comorbidity index ≥ 4, and pN stage were independent predictors of decreased overall survival rates in the VE group. A multivariate analysis showed total gastrectomy, a Charlson comorbidity index ≥ 4, and the pN stage to be independent predictors in the VE group. CONCLUSION: LG for gastric cancer is, thus, considered to be safe for patients aged 80 years or older. Total gastrectomy, a Charlson comorbidity index ≥ 4, and the pN stage were independent risk factors for a poor prognosis in these patients.

Laparoscopic duodenojejunostomy requiring a side-to-side jejunojejunostomy in malignant stenosis of the gastrojejunal anastomosis in jejunal cancer: A case report.

INTRODUCTION: Laparoscopic duodenojejunostomy is a common surgical treatment for SMA syndrome. Although there are successful cases of laparoscopic duodenojejunostomies on malignant conditions, cancer patients with opioid-induced bowel dysfunction could struggle in maintaining an oral diet despite surgical treatment of the mechanical obstruction. CASE PRESENTATION: A 66 year-old woman with a chemotherapy history of 18 months for Stage 4 jejunal cancer near the ligament of Treiz presented with vomiting and dehydration. She had a gastrojejunostomy constructed prior to the induction of chemotherapy. CT scan and endoscopic studies confirmed the stricture of this anastomosis due to tumor invasion. Laparoscopic duodenojejunostomy was performed, but tolerable food intake was not achieved, likely due to limited bowel movements caused by opioid use and tumor invasion of the celiac plexus. A side-to-side jejunojejunostomy was constructed, since accumulation of food in her jejunal loop was thought to be a significant cause of her limited food intake and vomiting. She was able to tolerate oral intake after the second intervention and was discharged home. DISCUSSION: Successful cases of laparoscopic duodenojejunostomy in malignant strictures of the duodenum have been reported. In this case, the outcome was not so well due to limited bowel movements caused by opioid use. Literature review of laparoscopic duodenojejunostomy on SMA syndrome revealed some cases to be unsuccessful in enabling oral feeding or resolving nausea, and methods to treat such cases could be discussed further. CONCLUSION: Laparoscopic duodenojejunostomy is an option for malignant strictures of the duodenum, but a favorable outcome could not be achieved in our case. A side to side anastomosis of the jejunal loop and the efferent jejunum may help in improving the outcome.

Does laparoscopic adhesiolysis decrease the risk of recurrent symptoms in small bowel obstruction? A propensity score-matched analysis.

BACKGROUND: The outcomes of laparoscopic adhesiolysis for small bowel obstruction have generally been satisfactory over the short term. However, the long-term outcomes, including recurrence of symptoms and management of recurrence, remain controversial. This study compares the long-term outcomes of a series of laparoscopic and open surgery procedures for the treatment of small bowel obstruction. METHODS: Patients who underwent adhesiolysis for small bowel obstruction at our institution between 2008 and 2015 were retrospectively reviewed. In total, 156 patients were enrolled, 78 with laparoscopic and 78 with open surgery. Propensity score matching was used to minimize the bias in patient selection. Long-term outcomes included incidence of recurrent symptoms and reoperation. In addition to the comparison of outcomes, risk factor assessment for recurrent symptoms and analysis of detailed information in patients with reoperation were performed. Statistical methods included χ 2 test, Mann-Whitney U test, Cox proportional hazards model, and Kaplan-Meier plots with log-rank comparison. RESULTS: Laparoscopy was performed in a younger population with milder bowel dilation and less complicated etiologies. These factors were used to construct the propensity score model, which yielded a matched cohort of 52 legs in each group. Laparoscopy achieved good short-term outcomes including early recovery of gastrointestinal function, reduced incidence of complications, and shorter hospital stay. For long-term outcomes, while the overall recurrence rate did not differ between the groups (11.5 vs 7.7%), the incidence of reoperation for recurrence was significantly higher in the laparoscopically treated group (7.7 vs 0%, p = .017). The Cox proportional hazards model showed that multiple prior surgeries (≥3 times) were a risk factor for overall recurrence (hazard ratio 7.39, p = .041). CONCLUSION: Laparoscopic adhesiolysis did not decrease the incidence of recurrent symptoms; rather, it was related to higher incidence of recurrent small bowel obstruction requiring surgical treatment.

Outcomes of laparoscopic management of acute small bowel obstruction: a 7-year experience of 110 consecutive cases with various etiologies.

PURPOSE: Laparoscopic surgery is emerging as an alternative to open surgery for treating acute small bowel obstruction (SBO). While postoperative adhesion is the most frequent etiology, the optimum treatment for all types of SBO needs to be evaluated. METHODS: A retrospective review was performed of 110 consecutive patients who underwent laparoscopic surgery at our institution between 2009 and 2015. The short-term outcomes included perioperative factors, while the long-term outcome included the recurrence rate. RESULTS: Of the 110 patients, 55 were female. The median age at surgery was 69.5 years. Laparoscopic surgery was completed in 91.8 %. The median operative time was 82 min, median amount of bleeding was 0 ml, and median postoperative hospital stay was 8 days. Intraoperative major organ injury was seen in 2.7 %. The complication rate (Clavien-Dindo ≥ class II) was 8.2 %, and the mortality rate was 3.6 %. The recurrence rate was 8.2 %. Only dense and matted adhesion was a predictive factor for conversion (OR 30.244). CONCLUSION: Good short-term outcomes and feasible long-term outcomes were achieved with a laparoscopic approach to treating acute SBO. It was a safe and effective method, especially in patients with isolated bands, simple enteral angulation, and foreign body or tumor, while dense and matted adhesions were still challenging.

Angiosarcoma of the breast - specific findings of MRI.

We present a case of low-grade angiosarcoma of the breast. A 26-year old woman presented with a lump in the left breast. An elastic hard and ill-defined tumor, 80 x 50 mm in size, was palpated in the upper region of her left breast. Mammography showed a dense lesion with poorly defined border. Ultrasonography showed a hyper-and hypo-echoic lesion with an unclear border, but no definite tumor. Fine needle aspiration cytology showed no evidence of malignancy. Therefore, she was followed with a diagnosis of mastopathy. Six months later, the lump got enlarged. A contrast-enhanced MRI of the breast was performed. It showed a 100 x 60 mm enhancing vascular mass. Most parts of the tumor enhanced remarkably at the early phase, and prolonged enhancement was recognized at the late phase. Core needle biopsy was performed, and a possible angiosarcoma was diagnosed. It is not easy to diagnose the mammary angiosarcoma. MRI may contribute to the accurate diagnosis and play an important role regarding this entity.
