Comparison of short-term outcomes of open and laparoscopic assisted pancreaticoduodenectomy for periampullary carcinoma: A propensity score-matched analysis

BACKGROUNDS/AIMS

Postoperative pancreatic fistula is the key worry in the ongoing debate about the safety and effectiveness of total laparoscopic pancreaticoduodenectomy (TLPD). Laparoscopic-assisted pancreaticoduodenectomy (LAPD), a hybrid approach combining laparoscopic resection and anastomosis with a small incision, is an alternative to TLPD. This study compares the short-term outcomes and oncological efficacy of LAPD vs. open pancreaticoduodenectomy (OPD).

METHODS

A retrospective analysis of data of all patients who underwent LAPD or OPD for periampullary carcinoma at a tertiary care center in Northeast India from July 2019 to August 2023 was done. A total of 30 LAPDs and 30 OPDs were compared after 1:1 propensity score matching. Demographic data, intraoperative and postoperative data (30 days), and pathological data were compared.

RESULTS

The study included a total of 93 patients, 30 underwent LAPD and 62 underwent OPD. After propensity score matching, the matched cohort included 30 patients in both groups. The LAPD presented several advantages over the OPD group, including a shorter incision length, reduced postoperative pain, earlier initiation of oral feeding, and shorter hospital stays. LAPD was not found to be inferior to OPD in terms of pancreatic fistula incidence (Grade B, 30.0% vs. 33.3%), achieving R0 resection (100% vs. 93.3%), and the number of lymph nodes harvested (12 vs. 14, p = 0.620). No significant differences in blood loss, short-term complications, pathological outcomes, readmissions, and early (30-day) mortality were observed between the two groups.

CONCLUSIONS

LAPD has comparable safety, technical feasibility, and short-term oncological efficacy.

Hybrid Laparoscopic Versus Open Pancreatoduodenectomy. A Meta-Analysis

INTRODUCTION

Hybrid laparoscopic techniques have been proposed as a good transition from open to complete minimally invasive approach especially in complex surgical procedures. This meta-analysis aimed to compare the outcomes of hybrid laparoscopic pancreatoduodenectomy versus open pancreatoduodenectomy.

METHODS

A systematic literature research was performed according to PRISMA guidelines. A broad search strategy with terms "laparoscopy" and "pancreatoduodenectomy" was used. Included studies were analyzed by quantitative meta-analysis using the metafor package for R software.

RESULTS

Of 655 identified articles, 627 were excluded and 28 articles fully assessed, including 14 comparative studies, 8 case series and 6 case reports. Extracted data included intraoperative variables and postoperative outcome parameters. The predefined inclusion criteria were met by 14 comparative studies, and 371 patients were pooled in the meta-analysis. Hybrid laparoscopic pacreatoduodenectomy was associated with significantly longer operative time (I² 0%, p = 0,01, Mean HPD 494,6 min, Mean OPD 421,6 min, WMD 67 min, 95% CI 14-120 min). For all other postoperative outcome parameters, no statistically significant differences were found. A nonsignificant reduction in intraoperative transfusion rate (I² 20%, p = 0,2, proportion HPD 2%, proportion OPD 1,6%, OR 0,44, 95% CI 0,16-1,27) and blood loss (I² 95%, p = 0,1, Mean HPD 397,2 ml, Mean OPD 1017,8 ml, MD - 601 ml, 95% CI - 1311-108) was observed for hybrid pancreatoduodenectomy in comparison to open surgery.

CONCLUSIONS

This meta-analysis demonstrates significantly increased operation time for hybrid laparoscopic compared to open pancreatoduodenectomy. Intraoperative variables as well as postoperative parameters and major morbidity were comparable for both techniques. Overall results of this meta-analysis demonstrated the hybrid technique as a safe procedure in high-volume centers offering aspects of a safe transition to fully laparoscopic pancreatoduodenectomy.

Minimally invasive pancreaticoduodenectomy for periampullary disease: a comprehensive review of literature and meta-analysis of outcomes compared with open surgery

BACKGROUND

Minimally invasive pancreatoduodenectomy (MIPD) has been gradually attempted. However, whether MIPD is superior, equal or inferior to its conventional open pancreatoduodenectomy (OPD) is not clear.

METHODS

Studies published up to May 2017 were searched in PubMed, Embase, Cochrane Library, and Web of Science. Main outcomes were comprehensively reviewed and measured including conversion to open approach, operation time (OP), estimated blood loss (EBL), transfusion, length of hospital stay (LOS), overall complications, postoperative pancreatic fistula (POPF), delayed gastric emptying (DGE), post-pancreatectomy hemorrhage (PPH), readmission, reoperation and reasons of preoperative death, number of retrieved lymph nodes (RLN), surgical margins, recurrence, and survival. The software of Review Manage version 5.1 was used for meta-analysis.

RESULTS

One hundred studies were included for systematic review and 26 out of them (totally 3402 cases, 1064 for MIPD, 2338 for OPD) were included for meta-analysis. In the early years, most articles were case reports or non-control case series studies, while in the last 6 years high-volume and comparative researches were increasing gradually. Systematic review revealed conversion rates of MIPD to OPD ranged from 0% to 40%. The mean or median OP of MIPD ranged from 276 to 657 min. The total POPF rates vary between 3.8% and 50% observed in all systematic reviewed studies. Meta-analysis demonstrated MIPD had longer OP (WMD = 99.4 min; 95%CI: 46.0 ~ 152.8, P < 0.01), lower blood loss (WMD = -0.54 ml; 95% CI, -0.88 ~ -0.20 ml; P < 0.01), lower transfusion rate (RR = 0.73, 95%CI: 0.57 ~ 0.94, P = 0.02), shorter LOS (WMD = -3.49 days; 95%CI: -4.83 ~ -2.15, P < 0.01). There was no significant difference in time to oral intake, postoperative complications, POPF, reoperation, readmission, perioperative mortality and number of retrieved lymph nodes.

CONCLUSION

Our study demonstrates MIPD is technically feasible and safety on the basis of historical studies. MIPD is associated with less blood loss, faster postoperative recovery, shorter length of hospitalization and longer operation time. These findings are waiting for being confirmed with robust prospective comparative studies and randomized clinical trials.

Robotic pancreaticoduodenectomy for pancreatic adenocarcinoma: role in 2014 and beyond

Minimally invasive surgery (MIS) for pancreatic adenocarcinoma has found new avenues for performing pancreaticoduodenectomy (PD) procedures, a historically technically challenging operation. Multiple studies have found laparoscopic PD to be safe, with equivalent oncologic outcomes as compared to open PD. In addition, several series have described potential benefits to minimally invasive PD including fewer postoperative complications, shorter hospital length of stay, and decreased postoperative pain. Yet, despite these promising initial results, laparoscopic PDs have not become widely adopted by the surgical community. In fact, the vast majority of pancreatic resections performed in the United States are still performed in an open fashion, and there are only a handful of surgeons who actually perform purely laparoscopic PDs. On the other hand, robotic assisted surgery offers many technical advantages over laparoscopic surgery including high-definition, 3-D optics, enhanced suturing ability, and more degrees of freedom of movement by means of fully-wristed instruments. Similar to laparoscopic PD, there are now several case series that have demonstrated the feasibility and safety of robotic PD with seemingly equivalent short-term oncologic outcomes as compared to open technique. In addition, having the surgeon seated for the procedure with padded arm-rests, there is an ergonomic advantage of robotics over both open and laparoscopic approaches, where one has to stand up for prolonged periods of time. Future technologic innovations will likely focus on enhanced robotic capabilities to improve ease of use in the operating room. Last but not least, robotic assisted surgery training will continue to be a part of surgical education curriculum ensuring the increased use of this technology by future generations of surgeons.

Laparoscopic pancreatectomy: Did the indications change? A review from literature

Pancreatic Cancer (PC) is the fourth cause of death for tumors in Western countries. Symptoms are not specific, and can vary according to the tumor size and place. Diagnostic workup includes CA 19-9, CT and MRI. Surgery is the only treatment for PC, associated to radio-chemo therapy. Laparoscopic approaches are actually used for PC treatment in few specialized centers, and could be an alternative to laparotomic surgery. The aim of our study is to evaluate the efficacy of laparoscopy for PC treatment compared to laparotomy. We reviewed 19 articles in literature to assess the feasibility and efficacy of Laparoscopic Distal Pancreatectomy (LDP) and Laparoscopic Pancreaticoduodenectomy (LPD). The results have shown that LDP is nowadays a safe technique, and the outcomes are comparable to laparotomic surgery. Regarding to LPD instead, results are controversial and the data are still not sufficient to consider this technique as a valid alternative to laparotomic surgery.

Conversion of laparoscopic surgery for perforated peptic ulcer: a single-center study

PURPOSE

A perforated peptic ulcer can be managed laparoscopically in selected patients. The purpose of this study was to evaluate whether conversion of emergency laparoscopy is inferior to primary median laparotomy in terms of postoperative morbidity and mortality.

METHODS

We analyzed patients who underwent laparoscopic or open surgery for a perforated peptic ulcer at the Department of Surgery, University of Schleswig-Holstein, Campus Luebeck between January, 1996 and December, 2010. Perforations were graded according to the Boey classification, a preoperative risk-scoring system.

RESULTS

Conversion to laparotomy was necessary in 20 of the 45 patients who underwent laparoscopic surgery (CG); therefore, laparoscopic operations were completed in 25 patients (LG). The third patient cohort comprised 139 patients who underwent primary laparotomy (OG). Overall minor morbidity was significantly lower (p = 0.048) in the LG patients than in the OG patients, whereas no significant differences were found in major morbidity and mortality, particularly between the OG and CG.

CONCLUSION

Patients' suitability for laparoscopic management should be decided on according to Boey's clinical scoring system. Our findings demonstrated that conversion from laparoscopy to laparotomy was not associated with elevated postoperative morbidity or mortality versus initial laparotomy. Therefore, emergency operations may be commenced laparoscopically in selected patients, especially considering the postoperative advantages of this approach.

Laparoscopic resection of pancreatic adenocarcinoma: Dream or reality?

Laparoscopic pancreatic surgery is in its infancy despite initial procedures reported two decades ago. Both laparoscopic distal pancreatectomy (LDP) and laparoscopic pancreaticoduodenectomy (LPD) can be performed competently; however when minimally invasive surgical (MIS) approaches are implemented the indication is often benign or low-grade malignant pathologies. Nonetheless, LDP and LPD afford improved perioperative outcomes, similar to those observed when MIS is utilized for other purposes. This includes decreased blood loss, shorter length of hospital stay, reduced post-operative pain, and expedited time to functional recovery. What then is its role for resection of pancreatic adenocarcinoma? The biology of this aggressive cancer and the inherent challenge of pancreatic surgery have slowed MIS progress in this field. In general, the overall quality of evidence is low with a lack of randomized control trials, a preponderance of uncontrolled series, short follow-up intervals, and small sample sizes in the studies available. Available evidence compiles heterogeneous pathologic diagnoses and is limited by case-by-case follow-up, which makes extrapolation of results difficult. Nonetheless, short-term surrogate markers of oncologic success, such as margin status and lymph node harvest, are comparable to open procedures. Unfortunately disease recurrence and long-term survival data are lacking. In this review we explore the evidence available regarding laparoscopic resection of pancreatic adenocarcinoma, a promising approach for future widespread application.

Bridging the gap between open and minimally invasive pancreaticoduodenectomy: the hybrid approach

BACKGROUND

Minimally invasive pancreatic surgery has evolved rapidly, but total laparoscopic pancreaticoduodenectomy has not been widely adopted owing to its technical complexity. Hybrid laparoscopy-assisted pancreaticoduodenectomy (HLAPD) combines the relative ease of open surgery with the benefits of a minimally invasive approach. This study evaluates the safety and effectiveness of the hybrid approach compared with open surgery.

METHODS

We retrospectively analyzed data of consecutive patients undergoing either hybrid or open pancreaticoduodenectomy (OPD) at our institution between September 2009 and December 2013. Demographic, operative and oncologic data were collected to compare outcomes between HLAPD and OPD.

RESULTS

Our analysis included 33 patients (HLAPD: n = 13; OPD: n = 20). There were no differences in patient demographics, comorbidities or surgical indications. The HLAPD group had significantly lower intraoperative blood loss (450 mL v. 1000 mL, p = 0.023) and shorter length of hospital stay (8 v. 12 d, p = 0.025) than the OPD group. Duration of surgery did not differ significantly between the groups. There were no differences in postoperative analgesic requirements, Clavien grade I/II or grade III/IV complications or 90-day mortality. Oncologic outcomes showed no significant differences in tumour size, R1 resection rate or number of lymph nodes harvested.

CONCLUSION

In select patients, HLAPD is a safe and effective procedure with comparable outcomes to conventional open surgery. Wider adoption of the hybrid approach will allow a greater number of patients to benefit from a less invasive procedure while facilitating the transition toward purely minimally invasive pancreaticoduodenectomy.

Laparoscopic pancreaticoduodenectomy: a systematic literature review

BACKGROUND

Laparoscopic pancreaticoduodenectomy (LPD) is gaining momentum, but there is still uncertainty regarding its safety, reproducibility, and oncologic appropriateness. This review assesses the current status of LPD.

METHODS

Our literature review was conducted in Pubmed. Articles written in English containing five or more LPD were selected.

RESULTS

Twenty-five articles matched the review criteria. Out of a total of 746 LPD, 341 were reported between 1997 and 2011 and 405 (54.2 %) between 2012 and June 1, 2013. Pure laparoscopy (PL) was used in 386 patients (51.7 %), robotic assistance (RA) in 234 (31.3 %), laparoscopic assistance (LA) in 121 (16.2 %), and hand assistance in 5 (0.6 %). PL was associated with shorter operative time, reduced blood loss, and lower rate of pancreatic fistula (vs LA and RA). LA was associated with shorter operative time (vs RA), but with higher blood loss and increased incidence of pancreatic fistula (vs PL and RA). Conversion to open surgery was required in 64 LPD (9.1 %). Operative time averaged 464.3 min (338-710) and estimated blood 320.7 mL (74-642). Cumulative morbidity was 41.2 %, and pancreatic fistula was reported in 22.3 % of patients (4.5-52.3 %). Mean length of hospital stay was 13.6 days (7-23), showing geographic variability (21.9 days in Europe, 13.0 days in Asia, and 9.4 days in the US). Operative mortality was 1.9 %, including one intraoperative death. No difference was noted in conversion rate, incidence of pancreatic fistula, morbidity, and mortality when comparing results from larger (≥30 LPD) and smaller (≤29 LPD) series. Pathology demonstrated ductal adenocarcinoma in 30.6 % of the specimens, other malignant tumors in 51.7 %, and benign tumor/disease in 17.5 %. The mean number of lymph nodes examined was 14.4 (7-32), and the rate of microscopically positive tumor margin was 4.4 %.

CONCLUSIONS

In selected patients, operated on by expert laparoscopic pancreatic surgeons, LPD is feasible and safe.

Laparoscopic pancreaticoduodenectomy assisted by mini-laparotomy

PURPOSE

Pancreaticoduodenectomy (PD) is the treatment of choice for periampullary disease. Even with the increasing number of successful reports from around the globe, laparoscopic pancreaticoduodenectomy (LPD) is still not fully accepted. We report the results of our experience of LPD assisted by mini-laparotomy.

METHOD

This retrospective review study included 42 patients who received LPD assisted by mini-laparotomy between March 2009 and April 2012. Clinical outcomes, such as patient age, pathologic diagnosis, pancreas nature, operation time, conversion rate, hospital stay, postoperative complication, and mortality rates, were reviewed.

RESULTS

A total of 42 patients (age range, 42 to 70 y ) received LPD assisted by mini-laparotomy. The mean incision length for the laparotomy was 5.2 cm. Mean operative time was 404 minutes, and 3 cases required conversion to open surgery. Mean postoperative hospital stay was 17 days. There were 3 cases of pancreaticogastrostomy leakage, 2 cases of postoperative bleeding, 4 cases of delayed gastric emptying, 1 case of bile leakage, and 5 cases of pulmonary complications. Of the 5 patients with pulmonary complications, 1 died.

CONCLUSIONS

When performed by a surgeon with ample experience in laparoscopic surgery, LPD assisted by mini-laparotomy is a safe, feasible alternative to conventional PD for select cases. The method described in this study can be used to perform pancreaticoenteric anastomosis in the same manner as an open PD, while taking advantage of the merits of minimally invasive surgery.

Minimalinvasive Chirurgie bei Malignomen des Gastrointestinaltrakts: Pankreas - Kontra-Position

<b><i>Hintergrund: </i></b>Für eine Vielzahl von Erkrankungen der Bauchspeicheldrüse gilt die chirurgische Resektion als die Therapie der Wahl. In den vergangenen Jahren wurden die offenen Operationsmethoden für Pankreaserkrankungen zunehmend standardisiert und können mittlerweile mit hoher Sicherheit durchgeführt werden. Unabhängig davon wird zunehmend über laparoskopische Pankreasresektionen berichtet. <b><i>Methode: </i></b>In diesem Artikel stellen wir die aktuelle Literatur zur minimalinvasiven Chirurgie der Bauchspeicheldrüse vor, um sie mit offenen Operationsverfahren zu vergleichen. Besondere Berücksichtigung finden laparoskopische und roboterassistierte Duodenopankreatektomien sowie laparoskopische Pankreasschwanzresektionen bei Patienten mit chronischer Pankreatitis sowie mit gutartigen und bösartigen Tumoren. <b><i>Ergebnisse: </i></b>Laparoskopische und roboterassistierte Pankreaskopfresektionen sollten nur in ausgewählten Fällen angewandt werden und gelten als technisch äußerst anspruchsvoll - mit einer erhöhten Inzidenz von Pankreasfisteln. Laparoskopische Pankreasschwanzresektionen sind sichere Verfahren mit einem Trend zu einer kürzeren Krankenhausaufenthaltsdauer, sollten jedoch nur für gutartige Tumoren in Betracht gezogen werden. Im Rahmen der onkologischen Chirurgie sollte die offene Pankreasresektion bevorzugt werden. Werden onkologische Eingriffe laparoskopisch durchgeführt, ist eine ausgezeichnete präoperative Diagnostik und gegebenenfalls der Einsatz eines intraoperativen laparoskopischen Ultraschalls notwendig. <b><i>Schlussfolgerungen: </i></b>Obwohl laparoskopische Pankreasresektionen in ausgewählten Fällen von Nutzen sein können, werden sie zukünftig wohl eher die Ausnahme darstellen. Eine allgemeine Umstellung auf laparoskopische Pankreasschwanzresektionen wird aufgrund des Mangels an eindeutigen Vorteilen gegenüber dem offenen Verfahren höchstwahrscheinlich nicht stattfinden.
