Extended left-sided pancreatectomy with spleen preservation

Simplicity and Safety: Minimized Pancreatic Fistula Rate after Distal Pancreatectomy through Pancreas Stump Sutured Fish-Mouth Closure

Pancreatic stump leak after distal pancreatectomy (DP) is a major determinant for impaired postoperative recovery. Factors influencing pancreatic fistula (PF) occurrence remain of interest. Prospectively collected data from an academic surgical oncology practice were examined for predictors of PF. Seventy-five of 294 pancreatectomy patients underwent DP (26%). There were 33 men and 42 women, with a median age of 61 years (range: 18–85 years). Underlying conditions included cancer (60%) and benign processes (40%). Resections were comprising open DP (64%), laparoscopic DP (21%), and open multivisceral resections (15%). Of 21 cases with postoperative complications (28%, no death), six were PFs (8%, 2 grade A and 4 grade B). The median length of stay was six days (4–24). The PF rate was 2.0 per cent in 50 patients after sutured fish-mouth closures, but 20 per cent in cases using other techniques including stapling ( P = 0.007); no other variable was linked to PF occurrence. Length of stay was linked to complications, resection extent, malignancy, and transfusions (all at P < 0.02), but not to PF. PF rate after DP in this experience is unaffected by splenic vessel resection but seems to be minimized through a sutured fish-mouth closure technique.

Laparoscopic left pancreatectomy: current concepts

The minimally invasive approach has been slow to gain acceptance in the field of pancreatic surgery even though its advantages over the open approach have been extensively documented in the medical literature. The reasons for the reluctant use of the technique are manifold. Laparoscopic distal or left sided pancreatic resections have slowly become the standard approach to lesions of the pancreatic body and tail as a result of evolution in technology and experience. A number of studies have shown the potential advantages of the technique in terms of safety, blood loss, oncological and economic feasibility, hospital stay and time to recovery from surgery. This review aims to provide an overview of the recent advances in the field of laparoscopic left pancreatectomy (LLP) and discuss potential future developments.

Laparoscopic pancreaticoduodenectomy and distal pancreatectomy: a UK experience and a systematic review of the literature

BACKGROUND

Advances in operative techniques and technology have facilitated laparoscopic distal pancreatectomy (LDP) and laparoscopic pancreaticoduodenectomy (LPD).

METHODS

All distal pancreatectomies were attempted laparoscopically, while selected patients underwent LPD. The literature was systematically reviewed.

RESULTS

Between 2002 and 2008, 21 patients underwent LDP (n=14) or LPD (n = 7). The mean operating time, blood loss, and hospital stay after LDP were 265 min, 262 ml, and 7.7 days, respectively, and after LPD they were 628 min, 350 ml, and 11.1 days, respectively. The conversion, morbidity, pancreatic fistula, readmission, reoperation, and mortality after LDP were 7.1, 35.7, 28.4, 28.4, 0, and 7.1% respectively, and after LPD they were 0, 28.6, 14.3, 28.6, 0, and 0% respectively. The literature review identified 987 LDP and 126 LPD. Most LDP were for benign disease (83.9%) while most LPD were for malignancy (91.5%). The mean operating time, morbidity, pancreatic fistula, mortality, and hospital stay after LDP were 221.5 min, 24.7%, 16.4%, 0.4%, and 7.7 days, respectively, and after LPD they were 448.3 min, 28.6%, 11.6%, 2.1%, and 16 days, respectively.

CONCLUSION

LDP, particularly for benign disease and low-grade malignancy, is increasingly becoming the gold standard approach in experienced hands. In selected patients, LPD is feasible and safe. Long-term follow-up data are needed.

Comparative study of laparoscopic and open distal pancreatectomy

BACKGROUND

Laparoscopic distal pancreatectomy (LDP) has been shown to be an effective surgical option for benign lesions in the body and tail of the pancreas. However, its advantages and disadvantages have not been well characterized. In this study, we compared the outcomes of LDP and open pancreatectomy performed in our clinic.

MATERIALS AND METHODS

Peri- and postoperative outcomes were retrospectively compared between patients with benign pancreatic disorders who underwent open distal pancreatectomy (ODP) (n = 35) and those who underwent LDP (n = 40). The peri- and postoperative factors analyzed included operative time, blood loss, hospital stay, postoperative recovery, biochemical findings, and complications.

RESULTS

LDP was associated with significantly less operative blood loss (363 versus 606 mL; P = 0.001) and shorter hospital stay (22 versus 27 day; P = 0.009), but longer operative time (342 versus 250 min; P = 0.000), compared with ODP. There were no significant differences between the two groups in complication rates or postoperative recovery, except for the significantly shorter duration of postoperative pain-killer intake and earlier improvement of the biochemical analysis in LDP than in ODP.

CONCLUSIONS

LDP appears to be a safe, desirable procedure for the management of benign pancreatic diseases, with outcomes similar to ODP.

The Clavien-Dindo classification of surgical complications: five-year experience

BACKGROUND AND AIMS

The lack of consensus on how to define and grade adverse postoperative events has greatly hampered the evaluation of surgical procedures. A new classification of complications, initiated in 1992, was updated 5 years ago. It is based on the type of therapy needed to correct the complication. The principle of the classification was to be simple, reproducible, flexible, and applicable irrespective of the cultural background. The aim of the current study was to critically evaluate this classification from the perspective of its use in the literature, by assessing interobserver variability in grading complex complication scenarios and to correlate the classification grades with patients', nurses', and doctors' perception.

MATERIAL AND METHODS

Reports from the literature using the classification system were systematically analyzed. Next, 11 scenarios illustrating difficult cases were prepared to develop a consensus on how to rank the various complications. Third, 7 centers from different continents, having routinely used the classification, independently assessed the 11 scenarios. An agreement analysis was performed to test the accuracy and reliability of the classification. Finally, the perception of the severity was tested in patients, nurses, and physicians by presenting 30 scenarios, each illustrating a specific grade of complication.

RESULTS

We noted a dramatic increase in the use of the classification in many fields of surgery. About half of the studies used the contracted form, whereas the rest used the full range of grading. Two-thirds of the publications avoided subjective terms such as minor or major complications. The study of 11 difficult cases among various centers revealed a high degree of agreement in identifying and ranking complications (89% agreement), and enabled a better definition of unclear situations. Each grade of complications significantly correlated with the perception by patients, nurses, and physicians (P < 0.05, Kruskal-Wallis test).

CONCLUSIONS

This 5-year evaluation provides strong evidence that the classification is valid and applicable worldwide in many fields of surgery. No modification in the general principle of classification is warranted in view of the use in ongoing publications and trials. Subjective, inaccurate, or confusing terms such as "minor or major" should be removed from the surgical literature.

Surgical strategies for treatment of malignant pancreatic tumors: extended, standard or local surgery?

Tumor related pancreatic surgery has progressed significantly during recent years. Pancreatoduodenectomy (PD) with lymphadenectomy, including vascular resection, still presents the optimal surgical procedure for carcinomas in the head of pancreas. For patients with small or low-grade malignant neoplasms, as well as small pancreatic metastases located in the mid-portion of pancreas, central pancreatectomy (CP) is emerging as a safe and effective option with a low risk of developing de-novo exocrine and/or endocrine insufficiency. Total pancreatectomy (TP) is not as risky as it was years ago and can nowadays safely be performed, but its indication is limited to locally extended tumors that cannot be removed by PD or distal pancreatectomy (DP) with tumor free surgical margins. Consequently, TP has not been adopted as a routine procedure by most surgeons. On the other hand, an aggressive attitude is required in case of advanced distal pancreatic tumors, provided that safe and experienced surgery is available. Due to the development of modern instruments, laparoscopic operations became more and more successful, even in malignant pancreatic diseases. This review summarizes the recent literature on the above mentioned topics.
