Background: This study aimed to determine the risk factors for severe postoperative complications in patients undergoing pure laparoscopic liver resection (LLR) for tumors in the right posterosuperior (PS) segments. Methods: The study included 289 patients who underwent parenchyma‐sparing pure LLR for tumors in the right PS segments at eight treatment centers between January 2009 and December 2019. Results: Multivariate analysis revealed tumor size ≥3 cm (P =.016), segmentectomy (P =.044), and liver cirrhosis (P =.029) as independent risk factors for severe postoperative complications. The severe complication rates (2.7% vs 12.1%, P =.0025), median intraoperative blood loss (100 mL vs 150 mL, P =.001), and median operation time (248 minutes vs 299.5 minutes, P =.0013) were lower in the patients without all these three risk factors than those with at least one risk factor. The median length of postoperative hospital stay was shorter in patients with no risk factors than those with at least one risk factor (9 days vs. 10 days, P =.001). Conclusions: Tumor size ≥3 cm, segmentectomy, and liver cirrhosis were the risk factors for severe postoperative complications after parenchyma‐sparing pure LLR for tumors in the right PS segments. Patients without these three risk factors would be appropriate candidates for safely performing parenchyma‐sparing pure LLR in the right PS segments at the outset. [ABSTRACT FROM AUTHOR]

Aim: Pancreaticodigestive tract anastomotic stricture is a long‐term complication of pancreticoduodenectomy (PD). However, optimal treatment has not yet been defined. We conducted longitudinal pancreaticojejunostomy (LPJ) in symptomatic patients with anastomotic stricture after PD. This study aimed to evaluate the efficacy of this procedure. Methods: Pancreticoduodenectomy was performed in 605 patients at our institution between January 2005 and April 2020. Of these, 15 patients (2.5%) developed symptomatic pancreaticodigestive tract anastomotic stricture after PD. Three patients were referred to our institution owing to recurrent pancreatitis with anastomotic stricture after PD. LPJ was indicated for these 18 patients, and they were enrolled in this study. Results: The median time from the initial operation to LPJ was 2.0 y. Preoperative clinical presentations included obstructive pancreatitis in 10 patients, a rapid deterioration of glucose tolerance in nine, and severe steatorrhea in two. Surgical morbidity ≥grade III defined by the Clavien–Dindo classification was not observed. After LPJ, preoperative symptoms improved in 16 patients (89%) during a median follow‐up of 39 mo. Nine of the 10 patients with obstructive pancreatitis achieved complete pain relief. All nine patients with a rapid deterioration of glucose tolerance showed improved endocrine function. Daily insulin requirement was significantly decreased after LPJ (11.6 ± 3.3 vs 3.4 ± 4.3 units, P =.0239). Four of the seven patients who required insulin injections were free of insulin after LPJ. Conclusion: LPJ is a safe and effective surgical procedure for symptomatic patients with stricture of the pancreaticodigestive tract anastomosis after PD. [ABSTRACT FROM AUTHOR]
