Introduction: An esophagojejunal anastomotic leak following an oncological gastrectomy is a life-threatening complication, and its management is challenging. A stent application and endoscopic negative pressure therapy are possible therapeutic options. A clinical comparison of these strategies has been missing until now. Methods: A retrospective analysis of 14 consecutive patients endoscopically treated for an anastomotic leak after a gastrectomy between June 2014 and December 2019 was performed. Results: The mean time of the diagnosis of the leakage was 7.14 days after surgery. Five patients were selected for a covered stent, and nine patients received endoscopic negative pressure therapy. In the stent group, the mean number of endoscopies was 2.4, the mean duration of therapy was 26 days, and the mean time of hospitalization was 30 days. In patients treated with endoscopic negative pressure therapy, the mean number of endoscopies was 6.0, the mean days of therapy duration was 14.78, and the mean days of hospitalization was 38.11. Treatment was successful in all patients in the stent-based therapy group and in eight of nine patients in the negative pressure therapy group. Discussion: Good clinical results in preserving the anastomosis and providing sepsis control was achieved in all patients. Stent therapy resulted in anastomosis healing with a lower number of endoscopies, a shorter time of hospitalization, and rapid oral nutrition.

Background: Perioperative hemodynamic instability is one of the most common adverse events in patients undergoing adrenalectomy for pheochromocytoma. The aim of this study was to analyze the impact of perioperative severe hemodynamic instability. Methods: We present a retrospective, single-center analysis in a major tertiary hospital of all consecutive patients undergoing elective adrenalectomy from 2005 to 2019 for pheochromocytoma. Severe perioperative hypertension and hypotension were evaluated, defined as changes in blood pressure larger than 30% of the preoperative patient-specific mean arterial pressure (MAP). Results: Unilateral adrenalectomy was performed in 67 patients. Intraoperative episodes of hemodynamic instability occurred in 97% of all patients (n = 65), severe hypertension occurred in 24 patients (36%), and severe hypotensive episodes occurred in 62 patients (93%). Patients with more than five severe hypotensive episodes (n = 29) received higher preoperative alpha-adrenergic blockades (phenoxybenzamine 51 ± 50 mg d−1 vs. 29 ± 27 mg d−1; p = 0.023) and had a longer mean ICU stay (39.6 ± 41.5 h vs. 20.6 ± 19.1 h, p = 0.015). Conclusion: Intraoperative hypotensive, rather than hypertensive, episodes occurred during adrenalectomy. The occurrence of more than five hypotensive episodes correlated well with a significantly longer hospital stay and ICU time.

Background and study aimEndoscopic negative pressure therapy (ENPT) is well established in the treatment of perforations of various etiologies in the upper and lower gastrointestinal tract. For duodenal perforations exist only case reports and series. Different indications are possible for ENPT in duodenal position: primary therapy for leaks, preemptive therapy after surgery for example, after ulcer suturing or resection with anastomoses, or as second line therapy in cases of recurrent anastomotic insufficiencies with leakage of duodenal secretion.MethodsA retrospective 4-year case series of negative pressure therapy in duodenal position indicated by different etiologies and a comprehensive review of current literature on endoscopic negative pressure duodenal therapy are presented.ResultsPatients with primary duodenal leaks n= 6 and with duodenal stump insufficiencies n = 4 were included. In seven patients ENPT was the first line and sole therapy. Primary surgery for duodenal leak was performed in n = 3 patients. Mean duration of ENPT was 11.0 days, mean hospital stay was 30.0 days. Re-operation after start of ENPT was necessary in two patients with duodenal stump insufficiencies. Surgery after termination of the ENPT was not necessary in any patient.DiscussionIn our case series and in the literature, ENPT has been shown to be very successful in the therapy of duodenal leaks. A challenge in ENPT for duodenal leaks is the appropriate length of the probe to safely reach the leak and keep the open pore element at the end of the probe in place despite intestinal motility.
