Background: Paraconduit hiatal hernia (PCHH) is a known complication of esophagectomy with significant morbidity. PCHH may be more common with the transition to a minimally invasive approach and improved survival. We studied the PCHH occurrence following minimally invasive esophagectomy to determine the incidence, treatment, and associated risk factors., Methods: We retrospectively reviewed records of patients who underwent esophagectomy at an academic tertiary care center between 2013-2020. We divided the cohort into those who did and did not develop PCHH, identifying differences in demographics, perioperative characteristics and outcomes. We present video of our laparoscopic repair with mesh., Results: Of 49 patients who underwent esophagectomy, seven (14%) developed PCHH at a median of 186 d (60-350 d) postoperatively. They were younger (57 versus 64 y, P< 0.01), and in cases of resection for cancer, more likely to develop tumor recurrence (71% versus 23%, P= 0.02). There was a significant difference in 2-y cancer free survival of patients with a PCHH (PCHH 19% versus no hernia 73%, P< 0.01), but no significant difference in 5-y overall survival (PCHH 36% versus no hernia 68%, P= 0.18). Five of seven PCHH were symptomatic and addressed surgically. Four PCHH repairs recurred at a median of 409 d., Conclusions: PCHH is associated with younger age and tumor recurrence, but not mortality. Safe repair of PCHH can be performed laparoscopically with or without mesh. Further studies, including systematic video review, are needed to address modifiable risk factors and identify optimal techniques for durable repair of post-esophagectomy PCHH., (Copyright © 2021.

Background: Eradication of Helicobacter pylori prior to Roux-en-Y gastric bypass (RYGB) has been advocated as a measure to reduce the complications of anastomotic ulceration. However, evidence to support a causal relationship between preoperative H. pylori status and postoperative anastomotic ulceration is weak.Methods: Intraoperative gastric biopsies were obtained on consecutive patients who underwent laparoscopic RYGB at our institution from December 2007 to June 2010. These samples were analyzed by Warthin-Starry stain for H. Pylori organisms. Retrospective chart review was conducted to determine the preoperative presence of acid dyspepsia and acid suppression therapy and to determine postoperative ulcer symptoms, smoking, NSAID or steroid use, and compliance with ulcer prophylaxis. The incidence of ulcer visualization, perforation, and stricture were obtained from a prospectively collected database. Fisher's exact test was used for analyzing associations between discrete groups. Multiple logistic regression was used to assess associations between anastomotic ulcer complications and potential predictors.Results: Histologic evaluation for H. pylori was available in 708 of the 728 patients who underwent RYGB. Fourteen patients were lost to follow up leaving 694 patients available for review. H. pylori was positive in 66 (9.5 %) patients who did not go on to receive definitive treatment for eradication. Marginal ulcers or related late complications were seen in a total of 113 (16.3 %) patients. In the H. pylori positive group, five patients (7.6 %) developed ulcer complications compared to 108 (17.1 %) in the H. pylori negative group (p = 0.05). Groups were not different in terms of preoperative demographics, postoperative ulcer prophylaxis compliance, steroid, NSAIDs, and cigarette use.Conclusion: The presence of H. pylori infection at the time of RYGB was found to be associated with a significantly lower incidence of anastomotic ulcer complications postoperatively. This study brings into question efforts and expense allocated to identify and eradicate H. pylori prior to RYGB. [ABSTRACT FROM AUTHOR]
