Frey’s procedure: short term follow up results in terms of pain, endocrine and exocrine status, a tertiary care centre experience

Background: Chronic pancreatitis, a debilitating disease which affects the patient to an extent to render him bedridden sometimes and often make him/her unable to perform daily work, leading to poor quality of life, severe emotional stress and financial burden. Frey’s procedure one of the most commonly performed surgery in patient of chronic pancreatitis with stones in pancreatic duct and small inflammatory head mass. This procedure had shown promising results in terms of pain control with unclear outcome with respect to exocrine and endocrine status.Methods: Study was conducted in Government Kilpauk Medical College, Chennai during March 2016 to December 2019. Total 21 patients were followed up for 18 months and Post-operative pain was analysed using pain scoring system used by Bloechle et al. Exocrine status in terms of diarrhea, bloating sensation and Fecal Elastase level(preoperative and postoperative) were analysed. Patient glycaemic status were also analysed and compared. Patient Nutritional status was analysed in terms of weight gain.Results: In this study there was significant improvement in pain after surgery in terms of VAS pain Score (Preop Mean-82.14, Post-op Mean- 9.76, p<0.001) , frequency of pain (Preop Mean-78.57, Post-op Mean- 14.29, p<0.001), analgesia required (Preop Mean-15, Post-op Mean- 3.10, p<0.001), and inability to work due to pain (Preop Mean-80.95, Post-op Mean- 11.90, p<0.001). Overall total Pain score was significantly improved after surgery (Preop Mean-256.67, Post-op Mean- 39.05, p<0.001). There was significant weight gain and significant improvement in Fecal Elastase level in patients following surgery, however there was no significant difference in pancreatic exocrine status on the basis of symptoms.Conclusions: Frey’s procedure is very effective in pain control in properly selected patients of chronic calcific pancreatitis, and it also improves nutritional status of patient. Frey’s procedure might improve patient exocrine and endocrine status but further multicentre studies are needed to come to a conclusion.

Frey’s procedure - does it improve quality of life? A single centre experience of long term outcome following Frey’s procedure

Background: The objective of the study was to find out long term outcome of patients who underwent Frey’s procedure for chronic calcific pancreatitis.Methods: This is a prospective observational study from retrospectively collected data of all patients who underwent Frey’s procedure for chronic calcific pancreatitis in Institute of Surgical Gastroenterology, Rajiv Gandhi Government General Hospital, Chennai from January 2012 to December 2014. All patients who have completed at least 48 months after surgery were followed up and their long-term postoperative quality of life were analyzed.Results: Totally 48 patients underwent Frey’s procedure during this period. Eight patients lost follow up. Preoperatively all patients had pain score above six in numerical rating scale but after surgery only two patients in the long term required stronger opioids for pain relief. Exocrine deficiency was present in 24 (60%) patients preoperatively, out of which seven patients showed improvement, eight patients had worsened exocrine deficiency and weight loss. Post operatively there were six patients who developed exocrine deficiency. Endocrine deficiency was seen in 23 (57.5%) patients preoperatively and during follow up none showed improvement, with two (5%) patients developed endocrine deficiency. Seven patients showed worsened endocrine deficiency as documented by increasing insulin requirement. Quality of life analysis using SF 36 showed poor quality of life in patients with worsened exocrine deficiency.Conclusions: Frey’s procedure although in long term showed improved outcome in terms of pain free survival and overall quality of life, exocrine and endocrine deficiency persisted in most and worsened in some patients.

Early outcome of Frey’s procedure for chronic pancreatitis: Nepalese tertiary center experience

Background Chronic pancreatitis is a progressive and persistent inflammatory disease resulting in pancreatic insufficiency leading to diabetes and steatorrhea. Abdominal pain is the most debilitating feature and is often refractory to treatment. Medical management with adequate analgesia and replacement of pancreatic enzyme supplements is the first line in management of chronic pancreatitis. Surgery is reserved for those who fail medical management. The choice of surgical procedure and timing of surgery is a topic of debate. The objective of this study was to analyze surgical safety along with short- and long- term outcomes of Frey’s procedure for patients suffering from chronic pancreatitis. Methods This was a retrospective review of cases of chronic pancreatitis who underwent Frey’s procedure from 2016 January to 2019 February at Tribhuvan University Teaching Hospital. Demographics, intraoperative findings, perioperative outcomes, and short- and long-time outcomes were analyzed. Results Total of 26 patients (age ranged 17–52, male − 14) underwent Frey’s procedure in the study period. Alcohol was etiology in six patients while the majority (76.9%) were nonalcoholic. Half of the patients had tropical pancreatitis. Intractable pain was present in all cases along with pseudocyst in three and pseudoaneurysm in one case. The mean preoperative Izbicki scores were 53.4 ± 17.6. Six patients had diabetes and two patients had steatorrhea. Major complications were seen in 11.5% of cases while mortality was in one patient. The median duration of the hospital stay was seven days. Over a median follow up of 17 months (range, 3–38), there were significantly lower pain scores postoperatively and 92% were pain-free. Only one new case of diabetes developed postoperatively. Conclusion Our early experiences suggests that Frey’s procedure can be a safe option for patients with chronic pancreatitis, with acceptable perioperative morbidity with adequate pain relief without worsening of pancreatic endocrine and exocrine function.
