Surgical management of Stapfer Type 2 ERCP perforations.

BACKGROUND: While numerous studies have proposed algorithms for the management of Stapfer Type 2 ERCP perforations, there is limited research on surgical treatment options specifically for this patient group. Our aim is not to propose a new algorithm for these patients but to describe our surgical approach and contribute to the literature with our surgical procedure applied in Stapfer Type 2 ERCP perforation cases. METHODS: Between 2016 and 2023, a total of 12 patients with Stapfer Type 2 ERCP perforations underwent surgery at our hospital. Duodenal diverticulization is a commonly used method in complex duodenal perforation cases. We performed a procedure that involves the removal of the external biliary pathway, hepaticojejunostomy, and a wide Braun anastomosis in addition to the duodenal diverticulization procedure, which we have termed "modified duodenal diverticulization." RESULTS: Eleven out of the 12 patients were discharged successfully without any complications. One patient, who had a late diagnosis, underwent surgery 5 days after ERCP. This patient had ongoing sepsis before the operation, which continued postoperatively and eventually led to multiple organ failure and death. CONCLUSION: There are limited alternatives for the surgical treatment of Type 2 ERCP perforations, and the widely preferred triple ostomy method may not address the underlying pathology necessitating ERCP. The modified duodenal diverticulization method, offering a definitive treatment, can be considered a surgical option for Type 2 ERCP perforations.

The use of Bakri balloon to reduce the anastomosis tension in hepaticojejunostomy.

One of the factors that impair anastomosis healing in patients undergoing hepaticojejunostomy is tension of the anastomosis. There may be tension, especially in cases with a short mesojejunum. In cases where the jejunum cannot be brought higher, positioning the liver a little lower may be a solution. We placed a Bakri balloon between the liver and diaphragm to position the liver to a lower level. Here we present a successful hepaticojejunostomy case in which we placed a Bakri balloon to decrease the anastomosis tension.

Subtype is a predictive factor of nonsentinel lymph node involvement in sentinel node-positive breast cancer patients.

PURPOSE: This study aimed to identify the effect of breast cancer subtype on nonsentinel lymph node (NSLN) metastasis in patients with a positive sentinel lymph node (SLN). METHODS: The records of 104 early breast cancer patients with a positive SLN between April 2009 and September 2013 were retrospectively evaluated. All patients underwent axillary lymph node dissection. The effects of the tumor subtype (luminal A, luminal/HER2+, human epidermal growth factor receptor 2 [HER2] overexpression, and triple-negative) and other clinicopathological factors on NSLN metastasis were examined by univariate and multivariate statistical analyses. RESULTS: Fifty of 104 patients (48%) exhibited NSLN metastasis. Univariate and multivariate analyses revealed that tumor size and the ratio of positive SLNs were significant risk factors of NSLN metastasis in patients with a positive SLN. The rate of NSLN metastasis was higher in patients with luminal/HER2+ and HER2 overexpression subtypes than that in patients with other subtypes in the univariate analysis (p<0.001). In the multivariate analysis, both patients with luminal/HER2+ (p<0.006) and patients with HER2 overexpression (p<0.031) subtypes had a higher risk of NSLN metastasis than patients with the luminal A subtype. CONCLUSION: Subtype classification should be considered as an independent factor when evaluating the risk of NSLN metastasis in patients with a positive SLN. This result supports the development of new nomograms including breast cancer subtype to increase predictive accuracy.
