Purpose: The aim of this study was to compare the clinical outcomes between laparoscopic partial liver resection and open partial hepatectomy for tumors in the posterosuperior segments.Methods: The clinical outcomes of patients who underwent either laparoscopic (n = 20) or open (n = 44) resection in segments 7/8 of the liver were initially evaluated. Because of disparities in the background characteristics, a case-matched study (1:1) was conducted. In addition, a comparative study of the patients who met the institutional criteria for laparoscopic partial hepatectomy was performed.Results: In the case-matched study, the laparoscopic technique required a longer operation time (p = 0.001), but was associated with less intraoperative blood loss (p = 0.021), a lower incidence of major complications (p = 0.014), higher levels of serum albumin on postoperative days 3 and 7 (p = 0.031 and p = 0.035), and earlier discharge (p = 0.001) than open resection. The results of the latter study were similar to those of the case-matched analysis.Conclusions: Laparoscopic partial hepatectomy was a feasible procedure for treating tumors in the posterosuperior segments without compromising oncological safety and yielded better short-term outcomes than open techniques. In addition, this study provides concrete selection criteria for laparoscopic partial hepatectomy for difficult lesions. [ABSTRACT FROM AUTHOR]

Purpose: The Frey procedure is an effective surgery for chronic pancreatitis (CP) patients who have pancreatic head lesions with dilation of the main pancreatic duct. However, pancreatic tail lesions can cause relapsing pancreatitis after the procedure. Therefore, additional distal pancreatectomy (DP) might complement the therapeutic effect of the Frey procedure in controlling inflammation of the pancreatic tail. The Frey procedure with DP (Frey + DP) is indicated for inflammatory lesions in the pancreatic head and tail. In this study, we assessed the usefulness of Frey + DP using the retrospective clinical data of our cases.Methods: The clinical outcomes were compared between CP patients who underwent the Frey procedure (N = 44) and Frey + DP (N = 13) from January 2005 to April 2016.Results: Frey + DP showed similarly good therapeutic effects to the Frey procedure with regard to the postoperative stay, morbidity, mortality, pain relief and nutrition, although the Frey + DP had a longer operative time, more bleeding and higher incidence of diabetes mellitus than the Frey procedure because of the additional DP. One patient in the Frey group received additional DP because of recurrent pain due to the tail lesion.Conclusion: Frey + DP can be a promising treatment for CP patients with pancreatic head and tail lesions.

Purpose: The aim of surgical intervention for chronic pancreatitis (CP) is to relieve symptoms and improve quality of life. However, the precise effect of surgery on the nutritional status of CP patients, which is often impaired by exocrine and endocrine pancreatic dysfunction, has not been elucidated. We conducted this study to evaluate whether Frey's procedure improves the nutritional status of CP patients. Methods: The nutritional status of 35 patients who underwent Frey's procedure for CP at our institute between April 2005 and December 2014, was assessed by the controlling nutritional status (CONUT) scoring before and 1 year after the surgery, and compared with that of seven CP patients who underwent pancreatoduodenectomy. The occurrence of postoperative hepatic steatosis was also monitored. Results: The nutritional status improved after Frey's procedure, but not after pancreatoduodenectomy. The median postoperative CONUT score after Frey's procedure was significantly lower than the preoperative score (1.0 ± 0.5 vs. 4.0 ± 2.5; p < 0.001). Conclusion: Frey's procedure is superior to pancreatoduodenectomy for improving the nutritional status of CP patients. [ABSTRACT FROM AUTHOR]
