Laparoscopic Lateral Pancreaticojejunostomy and Laparoscopic Berne Modification of Beger Procedure for the Treatment of Chronic Pancreatitis: The First UK Experience

Nonalcoholic fatty liver disease following laparoscopic duodenum-preserving pancreatic total head resection vs laparoscopic pancreaticoduodenectomy: A retrospective cohort study

BACKGROUND

Non-alcoholic fatty liver disease (NAFLD) is characterized by the accumulation of fat in the liver in individuals who do not consume alcohol. Several risk factors influencing the onset of NAFLD after laparoscopic pancreaticoduodenectomy (LPD) have been identified. This study investigated the risk factors associated with the development of fatty liver after laparoscopic duodenum-preserving pancreatic total head resection (LDPPHRt) and LPD.

AIM

To compare the effects of LDPPHRt and LPD on the development of postoperative NAFLD.

METHODS

This retrospective cohort study included 59 patients who were histologically diagnosed with benign or low-grade malignant pancreatic tumors and who underwent laparoscopic pancreatic surgery (LDPPHRt or LPD) between May 2020 and April 2023. Patient data on perioperative and postoperative variables were analyzed and compared. Multivariate logistic regression was used to identify pre-, peri-, and postoperative risk factors for NAFLD, with statistical significance set at P < 0.05.

RESULTS

Of the 59 patients included in the study, 17 (28.8%) developed NAFLD within 6-12 months post-surgery. The incidence of NAFLD was significantly higher in the LPD group compared to the LDPPHRt group (40.0% vs 12.5%, P = 0.022). Multivariable analysis identified the LDPPHRt surgical approach (compared to LPD) as an independent protective factor against the development of postoperative NAFLD, with an odds ratio of 0.208 (95% confidence interval: 0.046-0.931; P = 0.040).

CONCLUSION

Our findings indicate that LDPPHRt is more effective than LPD in reducing the incidence of postoperative NAFLD, which may inform surgical decision-making and optimize patient outcomes after laparoscopic pancreatic surgery.

Minimally invasive versus open lateral pancreaticojejunostomy in patients with painful chronic pancreatitis: systematic review

BACKGROUND

Patients with painful chronic pancreatitis combined with a dilated main pancreatic duct and a normal size pancreatic head are treated according to guidelines by lateral pancreaticojejunostomy (LPJ). This systematic review compared outcomes of minimally invasive LPJ and open LPJ.

METHODS

From 1 January 2000 until 13 November 2023, series reporting on minimally invasive LPJ and open LPJ in patients with symptomatic chronic pancreatitis were included. This study was structured in accordance with the PRISMA guidelines. The primary outcome was intraoperative and postoperative complications. Secondary outcomes included long-term clinical outcomes.

RESULTS

Overall, 19 retrospective studies were included. Morbidity rate ranged from 0% to 57% after minimally invasive LPJ versus 4% to 68% after open LPJ (median: 25, i.q.r.: 23). Length of hospital stay ranged from 5 to 7 days after minimally invasive LPJ and from 6 to 16 days after open LPJ. The rate of pain relief ranged from 62% to 91% after open LPJ (median: 78.5, i.q.r.: 23) and from 71% to 100% (median: 82.5, i.q.r.: 12.5) after minimally invasive LPJ respectively. New-onset endocrine insufficiency ranged from 21% to 22% in minimally invasive LPJ and 19% to 26% after open LPJ. New-onset exocrine insufficiency was shown in 11% to 27% in minimally invasive LPJ versus 8% to 26% after open LPJ. Weight gain ranged from 60% to 100% (median: 97, i.q.r.: 23) after minimally invasive LPJ.

DISCUSSION

This systematic review suggested that minimally invasive LPJ can be performed safely in selected patients with symptomatic chronic pancreatitis. Phase 2 randomized trials should assess potential short-term benefits such as postoperative pain and length of hospital stay after minimally invasive LPJ.

Changing trends in the minimally invasive surgery for chronic pancreatitis

Chronic pancreatitis is a debilitating pancreatic inflammatory disease characterized by intractable pain resulting in poor quality of life. Conventional management of pancreatic pain consists of a step-up approach with medications and lifestyle modifications followed by endoscopic intervention. Traditionally surgery is reserved for patients who do not improve with other interventions. However, recent studies suggest that early surgical intervention is more beneficial as it can mitigate the progression of the pathological process and prevent loss of pancreatic function. Despite the widespread adoption of minimally invasive approaches in various gastrointestinal surgical disorders, minimally invasive surgery for chronic pancreatitis is slow to evolve. Technical difficulty due to severe inflammatory changes has been the major impediment to the widespread usage of minimally invasive surgery in chronic pancreatitis. With this background, the present review aimed to critically analyze the available evidence on the minimally invasive treatment of chronic pancreatitis. A Pub Med search of all relevant articles was performed using the appropriate keywords, parentheses, and Boolean operators. Most initial laparoscopic series have reported the feasibility of lateral pancreaticojejunostomy, considered an adequate procedure only in a small proportion of patients. The pancreatic head is the pacemaker of pain, so adequate decompression is critical for long-term pain relief. Recent studies have documented the feasibility of minimally invasive duodenum-preserving pancreatic head resection. With improvements in laparoscopic instrumentation and technological advances, minimally invasive surgery for chronic pancreatitis is gaining momentum. However, more high-quality evidence is required to document the superiority of minimally invasive surgery for chronic pancreatitis.

Laparoscopic longitudinal pancreaticojejunostomy for chronic pancreatitis: Systematic review of the literature

BACKGROUND

Longitudinal pancreaticojejunostomy, also known as modified Puestow or Partington-Rochelle procedure, is a technique for the treatment of chronic pancreatitis. It is usually performed by laparotomy, but in a very small number of cases it has been performed using a laparoscopic or robot-assisted approach. We carried out a systematic literature review to clarify the current status of laparoscopic longitudinal pancreatojejunostomy (LLPJ).

METHODS

Adhering to the PRISMA guidelines, a systematic search for LLPJ was performed in PubMed, Embase, and Cochrane Library, for articles published up to 31 December 2017.

RESULTS

357 articles were evaluated for eligibility and 17 were included for critical appraisal: eight case reports, eight retrospective case series, and one series of cases and controls without randomization. All of them had a grade of recommendation C and a level of evidence 4 according to the CEBM. Patients were relatively young (mean age 37 years), with a slight preponderance of males (ratio 1.3: 1). All had long-standing disease, ERCP prior to surgery and a dilated pancreatic duct (mean 11 mm). The surgery was usually performed laparoscopically using four trocars; the conversion rate was low (5%), bleeding was minimal, the morbidity rate was 11% and no mortality was reported. Mean hospital stay was 5.6 days. The follow-up period varied but was usually short (less than two years). The results for pain control were very good since 90% of patients reported no pain, although visual analog scales were rarely used.

CONCLUSIONS

In conclusion, LLPJ seems to be a safe, feasible and effective technique in patients with chronic pancreatitis. However, the number of descriptions published to date is very small, and there are no studies with high scientific evidence comparing LLPJ with open surgery or with endoscopic treatment that would allow us to draw firmer conclusions at the present time.

Laparoscopic Beger procedure for the treatment of chronic pancreatitis: a single-centre first experience

Background

The Beger procedure is a common surgical option in the management of the unremitting abdominal pain of chronic pancreatitis (CP). As an organ-sparing surgery, it might be a better choice than pancreatoduodenectomy (PD). However, it is rather challenging for surgeons to perform the Beger procedure laparoscopically, especially for patients with CP; indeed, it has rarely reported. Here, we describe the technique and results of our early experience in laparoscopic Beger procedure for the treatment of CP.

Case presentation

Five patients (1 male) with CP (alcohol induced, n = 3; idiopathic, n = 2) who underwent laparoscopic Beger procedure from May to October 2019 in West China Hospital were included in this study. The median pancreatic duct diameter was 6.8 (4 to 12) mm. The median operating time was 275 (150 to 305) minutes without conversion. Only one patient (20%) developed a grade B pancreatic fistula. One patient required re-operation for jejunal anastomotic bleeding on the first post-operative day. The median hospital stay was 11 (9 to 34) days. No patient experienced biliary fistula, gastroparesis, duodenal necrosis, or abdominal bleeding. The 90-day mortality rate was 0%. All the patients were pain free in the two months after the operation.

Conclusion

The laparoscopic Beger procedure is feasible and safe with good short-term results and some potential benefits in selected patients with chronic pancreatitis. Further study and longer follow-up are required.

Laparoscopic surgery in pancreatic diseases: Pushing the boundaries

BACKGROUND

Laparoscopic surgery has expanded exponentially in the last two decades but, somehow it is limited in pancreatic surgery by virtue of the pancreas being a friable, retroperitoneal organ with difficult access and adjacent major vessels risking torrential bleed. It is thought to be unforgiving if not handled well. However, improvements in technology and surgeon's expertise have pushed the boundaries of minimal access surgery (MAS) to include pancreas in its domain. We present our series of laparoscopic pancreatic surgery (LPS) with an aim to look at the feasibility and outcomes.

METHODS

This is a retrospective review of all LPS done at the Gastrointestinal Surgery (GIS) centre of a tertiary care Armed Forces Hospital over a period of 3 years.

RESULTS

A total of 24 LPS were done during this period. The median age of the patients was 46 years (range; 13-81). There were 14 male and 10 female patients. Nine patients had at least one co-morbidity. Three patients underwent laparoscopic lateral pancreaticojejunostomy, 4 distal pancreatectomy, 4 laparoscopic Whipples pancreaticoduodenectomy, 6 laparoscopic pancreatic necrosectomy, 6 laparoscopic cystogastrostomy and 1 roux en y cystojejunostomy.

CONCLUSION

LPS can be performed for almost all open pancreatic surgeries and can be done with reasonable outcomes. However, it has a steep learning curve and therefore, a hybrid approach leading to a totally laparoscopic approach may be the way forward.

Matched Case-Control Comparative Study of Laparoscopic Versus Open Pancreaticoduodenectomy for Malignant Lesions

INTRODUCTION

Advances in surgical technologies allowed safe laparoscopic pancreaticoduodenectomy (LPD). The aim of this study is to compare the oncologic outcomes of LPD to open pancreaticoduodenectomy (OPD) in terms of safety and recurrence rate.

MATERIALS AND METHODS

A cohort of 30 patients were matched for age, sex, American Society of Anaesthesiologists, tumor size, pancreatic duct diameter, and histopathologic diagnosis on a 1:1 basis (15 LPD, 15 OPD). Comparison between groups was performed on intention-to-treat basis. Survival following resection was compared using the Kaplan-Meier survival analysis.

RESULTS

The median operating time for LPD group was longer than for OPD group (470 vs. 310 min; P=0.184). However, estimated blood loss (300 vs. 620 mL; P=0.023), high dependency unit stay (2.0 vs. 6.0 d; P=0.013) and postoperative hospital stay (9.0 vs. 17.4 d; P=0.017) were significantly lower in the LPD group. There was no significant difference in postoperative rates of morbidity (40% vs. 67%; P=0.431) and mortality (0% vs. 6.7%; P=0.99). The surgical resection margins R0 status (87% vs. 73%; P=0.79) and the number of lymph nodes (18 vs. 20; P=0.99) in the resected specimens were comparable between the 2 groups. There was no significant difference in overall survival outcomes.

CONCLUSIONS

In selected patients, the laparoscopic approach to pancreaticoduodenectomy in the hands of the experienced offers advantages over open surgery without compromising the oncologic resection.

[Laparoscopic pancreatic head resection]

AIM

To analyze the features and efficacy of laparoscopic Frey procedure.

MATERIAL AND METHODS

For the period from August 2012 to May 2017 Frey procedure was carried out in 31 patients with chronic calculous pancreatitis Buchler type C. There were 20 men and 11 women aged 48.6±9 years. Mean pancreatic head dimension was 35.5±14 mm, diameter of the main pancreatic duct - 9.6±2.7 mm.

RESULTS

Completely laparoscopic procedure was made in 28 (90.3%) cases. One patient required intraoperatively Beger's technique without conversion. The last was need in 2 (6.5%) cases. Time of surgery and blood loss were 447.3±90.4 min and 215±177.7 ml respectively. Mean postoperative hospital-stay was 8.4±4.5 days. Postoperative complications occurred in 7 patients. Mortality was absent. Follow-up was 1-41 months. Recurrent pain syndrome was observed in 1 case. However, it was less severe and does not require analgesia.

Safety and feasibility of the robotic platform in the management of surgical sequelae of chronic pancreatitis

BACKGROUND/AIM

The application of minimally invasive surgery to chronic pancreatitis (CP) procedures is uncommon. Our objective was to report the safety and feasibility of the robotic approach in the treatment of surgical sequelae of CP, and provide insights into the technique, tricks, and pitfalls associated with the application of robotics to this challenging disease entity.

METHODS

A retrospective review of a prospectively maintained database of patients undergoing robotic-assisted resections and/or drainage procedures for CP at the University of Pittsburgh between May 2009 and January 2017 was performed. A video of a robotic Frey procedure is also shown.

RESULTS

Of 812 robotic pancreatic resections and reconstructions 39 were for CP indications. These included 11 total pancreatectomies [with and without auto islet transplantation], 8 Puestow procedures, 4 Frey procedures, 6 pancreaticoduodenectomies, and 10 distal pancreatectomies. Median age was 49, and 41% of the patients were female. The most common etiology for CP was idiopathic pancreatitis (n = 16, 46%). Median operative time was 324 min with a median estimated blood loss of 250 ml. None of the patients required conversion to laparotomy. A Clavien III-IV complication rate was experienced by 5 (13%) patients, including one reoperation. Excluding the eleven patients who underwent TP, rate of clinically relevant postoperative pancreatic fistula was 7% (Grade B = 2, Grade C = 0). No 30 or 90 day mortalities were recorded. The median length of hospital stay was 7 days.

CONCLUSIONS

Use of the robotic platform is safe and feasible when tackling complex pancreatic resections for sequelae of chronic pancreatitis.

Surgical approaches to chronic pancreatitis: indications and imaging findings

Chronic pancreatitis (CP) is an irreversible, inflammatory process characterized by progressive fibrosis of the pancreas that can result in abdominal pain, exocrine insufficiency, and diabetes. Inadequate pain relief using medical and/or endoscopic therapies is an indication for surgery. The surgical management of CP is centered around three main operations including pancreaticoduodenectomy (PD), duodenum-preserving pancreatic head resection (DPPHR) and drainage procedures, and total pancreatectomy with islet autotransplantation (TPIAT). PD is the method of choice when there is a high suspicion for malignancy. Combined drainage and resection procedures are associated with pain relief, higher quality of life, and superior short-term and long-term survival in comparison with the PD. TPIAT is a reemerging treatment that may be promising in subjects with intractable pain and impaired quality of life. Imaging examinations have an extensive role in pre-operative and post-operative evaluation of CP patients. Pre-operative advanced imaging examinations including CT and MRI can detect hallmarks of CP such as calcifications, pancreatic duct dilatation, chronic pseudocysts, focal pancreatic enlargement, and biliary ductal dilatation. Post-operative findings may include periportal hepatic edema, pneumobilia, perivascular cuffing and mild pancreatic duct dilation. Imaging can also be useful in the detection of post-operative complications including obstructions, anastomotic leaks, and vascular lesions. Imaging helps identify unique post-operative findings associated with TPIAT and may aid in predicting viability and function of the transplanted islet cells. In this review, we explore surgical indications as well as pre-operative and post-operative imaging findings associated with surgical options that are typically performed for CP patients.

Surgical Management of Chronic Pancreatitis

Advances over the past decade have indicated that a complex interplay between environmental factors, genetic predisposition, alcohol abuse, and smoking lead towards the development of chronic pancreatitis. Chronic pancreatitis is a complex disorder that causes significant and chronic incapacity in patients and a substantial burden on the society. Major advances have been made in the etiology and pathogenesis of this disease and the role of genetic predisposition is increasingly coming to the fore. Advances in noninvasive diagnostic modalities now allow for better diagnosis of chronic pancreatitis at an early stage of the disease. The impact of these advances on surgical treatment is beginning to emerge, for example, patients with certain genetic predispositions may be better treated with total pancreatectomy versus lesser procedures. Considerable controversy remains with respect to the surgical management of chronic pancreatitis. Modern understanding of the neurobiology of pain in chronic pancreatitis suggests that a window of opportunity exists for effective treatment of the intractable pain after which central sensitization can lead to an irreversible pain syndrome in patients with chronic pancreatitis. Effective surgical procedures exist for chronic pancreatitis; however, the timing of surgery is unclear. For optimal treatment of patients with chronic pancreatitis, close collaboration between a multidisciplinary team including gastroenterologists, surgeons, and pain management physicians is needed.
