Minimally invasive surgery for inflammatory bowel disease: Review of current developments and future perspectives

Patients with inflammatory bowel disease(IBD)com-prise a population of patients that have a high likelihood of both surgical treatment at a young age and repetitive operative interventions.Therefore surgical procedures need to aim at minimizing operative trauma with bestpostoperative recovery.Minimally invasive techniques have been one of the major advancements in surgery in the last decades and are nowadays almost routinely performed in colorectal resections irrespective of underlying disease.However due to special disease related characteristics such as bowel stenosis,interen-teric fistula,abscesses,malnutrition,repetitive sur-geries,or immunosuppressive medications,patients with IBD represent a special cohort with specific needs for surgery.This review summarizes current evidence of minimally invasive surgery for patients with Crohn’s disease or ulcerative colitis and gives an outlook on the future perspective of technical advances in this highly moving field with its latest developments in single port surgery,robotics and trans-anal techniques.

Minimally invasive surgery for inflammatory bowel disease: Current perspectives

The surgical management of complicated and recurrent inflammatory bowel disease(IBD),has remained a challenge.Minimally invasive surgery(MIS),in the form of laparoscopic resections,single port approach and robotic-assisted dissections in the management of IBD,have been examined in several prospective studies.All of them have shown advantages over open surgeryin terms of reduction of physical trauma of surgery,recovery time,better cosmetic outcomes and shorter hospitalization.However,it is important to appreciate that not all patients with IBD are suitable for MIS,so a combination of both open and MIS should be adopted to achieve optimum outcomes.A review on this subject performed by Neumann et al in this issue of World Journal of Gastrointestinal Pharmacology and Therapeutics have provided evidence in support of the contemporary practice of MIS in the management of IBD and the accompanying commentary further critically evaluates their application in clinical practice.

Minimally invasive surgery for glycogen storage disease combined with inflammatory bowel disease:A case report

BACKGROUND Inflammatory bowel disease(IBD)is rare in patients with glycogen storage disease(GSD).In GSD patients,a decrease in the number of neutrophils leads to prolonged intestinal infection,leading to the formation of chronic inflammation and eventually the development of IBD.Minimally invasive surgery for patients with IBD has been proven to reduce inflammatory responses and postoperative risks and ultimately promote rapid recovery.Herein we discuss minimally invasive surgery and the perioperative management in a patient with GSD and IBD.CASE SUMMARY A 23-year-old male had GSD Ib associated with IBD-like disease for 10 years.Despite standard treatments,such as mesalazine,prednisone and adalimumab,the patient eventually developed colonic stenosis with incomplete ileus.After adequate assessment,the patient was treated with minimally invasive surgery and discharged in stable condition.CONCLUSION Minimally invasive surgery for patients with IBD and GSD is safe,feasible and effective.

Exploring the landscape of minimally invasive pancreatic surgery: Progress, challenges, and future directions

Minimally invasive surgery(MI)has become the standard of care for many surgical procedures aimed at reducing the burden on patients.However,its adoption in pancreatic surgery(PS)has been limited by the pancreas’s unique location and the complexity of the dissection and reconstruction phases.These factors continue to contribute to PS having one of the highest morbidity and mortality rates in general surgery.Despite a rough start,MIPS has gained widespread acceptance in clinical practice recently.Robust evidence supports MI distal pancreatectomy safety,even in oncological cases,indicating its potential superiority over open surgery.However,definitive evidence of MI pancre-aticoduodenectomy(MIPD)feasibility and safety,particularly for malignant lesions,is still lacking.Nonetheless,reports from high-volume centers are emer-ging,suggesting outcomes comparable to those of the open approach.The robotic PS increasing adoption,facilitated by the wider availability of robotic platforms,may further facilitate the transition to MIPD by overcoming the technical con-straints associated with laparoscopy and accelerating the learning curve.Alth-ough the MIPS implementation process cannot be stopped in this evolving world,ensuring patient safety through strict outcome monitoring is critical.Investing in younger surgeons with structured and recognized training programs can promote safe expansion.

Present situation of minimally invasive surgical treatment for early gastric cancer

Minimally invasive surgery is a kind of surgical operation,which is performed by using professional surgical instruments and equipment to inactivate,resect,repair or reconstruct the pathological changes,deformities and wounds in human body through micro-trauma or micro-approach,in order to achieve the goal of treatment,its surgical effect is equivalent to the traditional open surgery,while avoiding the morbidity of conventional surgical wounds.In addition,it also has the advantages of less trauma,less blood loss during operation,less psychological burden and quick recovery on patients,and these minimally invasive techniques provide unique value for the examination and treatment of gastric cancer patients.Surgical minimally invasive surgical techniques have developed rapidly and offer numerous options for the treatment of early gastric cancer(EGC):endoscopic mucosal resection(EMR),underwater EMR(UEMR),endoscopic submucosal dissection(ESD),endoscopic full-thickness resection(EFTR),endoscopic submu-cosal excavation(ESE),submucosal tunnel endoscopic resection,laparoscopic and endoscopic cooperative surgery(LECS);Among them,EMR,EFTR and LECS technologies have a wide range of applications and different modific-ations have been derived from their respective surgical operations,such as band-assisted EMR(BA-EMR),conven-tional EMR(CEMR),over-the-scope clip-assisted EFTR,no-touch EFTR,the inverted LECS,closed LECS,and so on.These new and improved minimally invasive surgeries are more precise,specific and effective in treating different types of EGC.

Impact of minimally invasive surgery on immune function and stress response in gastric cancer patients

BACKGROUND Gastric cancer remains a leading cause of cancer-related mortality globally.Traditional open surgery for gastric cancer is often associated with significant morbidity and prolonged recovery.AIM To evaluate the effectiveness of laparoscopic minimally invasive surgery as an alternative to traditional open surgery for gastric cancer,focusing on its potential to reduce trauma,accelerate recovery,and achieve comparable oncological out-comes.METHODS This study retrospectively analyzed 203 patients with gastric cancer who underwent surgery at the Shanghai Health Medical College Affiliated Chongming Hospital from January 2020 to December 2023.The patients were divided into two groups:Minimally invasive surgery group(n=102),who underwent laparoscopic gastrectomy,and open surgery group(n=101),who underwent traditional open gastrectomy.We compared surgical indicators(surgical incision size,intraop-erative blood loss,surgical duration,and number of lymph nodes dissected),recovery parameters(time to first flatus,time to start eating,time to ambulation,and length of hospital stay),immune function(levels of IgA,IgG,and IgM),intestinal barrier function(levels of D-lactic acid and diamine oxidase),and stress response(levels of C-reactive protein,interleukin-6,and procalcitonin).RESULTS The minimally invasive surgery group demonstrated significantly better outcomes in terms of surgical indicators,including smaller incisions,less blood loss,shorter surgery time,and more lymph nodes dissected(P<0.05 for all).Recovery was also faster in the minimally invasive surgery group,with earlier return of bowel function,earlier initiation of diet,quicker mobilization,and shorter hospital stays(P<0.05 for all).Furthermore,patients in the minimally invasive surgery group had better preserved immune function,superior intestinal barrier function,and a less pronounced stress response postoperatively(P<0.05 for all).CONCLUSION Laparoscopic minimally invasive surgery for gastric cancer not only provides superior surgical indicators and faster recovery but also offers advantages in preserving immune function,protecting intestinal barrier function,and mitigating the stress response compared to traditional open surgery.These findings support the broader adoption of laparoscopic techniques in the management of gastric cancer.

Role of minimally invasive surgery for rectal cancer

Rectal cancer is one of the most common malignancies worldwide.Surgical resection for rectal cancer usually requires a proctectomy with respective lymphadenectomy(total mesorectal excision).This has traditionally been performed transabdominally through an open incision.Over the last thirty years,minimally invasive surgery platforms have rapidly evolved with the goal to accomplish the same quality rectal resection through a less invasive approach.There are currently three resective modalities that complement the traditional open operation:(1)Laparoscopic surgery;(2)Robotic surgery;and(3)Transanal total mesorectal excision.In addition,there are several platforms to carry out transluminal local excisions(without lymphadenectomy).Evidence on the various modalities is of mixed to moderate quality.It is unreasonable to expect a randomized comparison of all options in a single trial.This review aims at reviewing in detail the various techniques in regard to intra-/perioperative benchmarks,recovery and complications,oncological and functional outcomes.

Transanal minimally invasive surgery using laparoscopic instruments of the rectum:A review

Transanal minimally invasive surgery(TAMIS)was first described in 2010 as an alternative to transanal endoscopic microsurgery(TEM).The TAMIS technique can be access to the proximal and mid-rectum for resection of benign and earlystage malignant rectal lesions and also used for noncurative intent surgery of more advanced lesions in patients who are not candidates for radical surgery.TAMIS has a shorter learning curve,reduced device setup time,flexibility in instrument use,and versatility in application than TEM.Also,TAMIS shows similar results in a view of the operation time,conversion rate,reoperation rate,and complication to TEM.For these reasons,TAMIS is an easily accessible,technically feasible,and cost-effective alternative to TEM.Overall,TAMIS has enabled the performance of high-quality local excision of rectal lesions by many colorectal surgeons.As TAMIS becomes more broadly utilized such as pelvic abscess drainage,rectal stenosis,and treatment of anastomotic dehiscence,the acquisition of appropriate training must be ensured,and the continued assessment and assurance of outcome must be maintained.

Laparoscopy for Crohn's disease:A comprehensive exploration of minimally invasive surgical techniques

BACKGROUND Along with the unceasing progress of medicine,Crohn's disease(CD),especially complex CD,is no longer a taboo for minimally invasive surgery.However,considering its special disease characteristics,more clinical trials are needed to confirm the safety and feasibility of laparoscopic surgery for CD.AIM To investigate the safety and feasibility of laparoscopic enterectomy for CD,assess the advantages of laparoscopy over laparotomy in patients with CD,and discuss comprehensive minimally invasive surgical techniques in complex CD.METHODS This study prospectively collected clinical data from patients with CD who underwent enterectomy from January 2017 to January 2020.It was registered in the Chinese clinical trial database with the registration number ChiCTR-INR-16009321.Patients were divided into a laparoscopy group and a traditional laparotomy group according to the surgical method.The baseline characteristics,operation time,intraoperative blood loss,temporary stoma,levels of abdominal adhesion,pathological characteristics,days to flatus and soft diet,postoperative complications,hospitalization time,readmission rate within 30 d,and hospitalization cost were compared between the two groups.RESULTS A total of 120 eligible patients were enrolled into the pre-standardized groups,including 100 in the laparoscopy group and 20 in the laparotomy group.Compared with the laparotomy group,the postoperative hospitalization time in the laparoscopy group was shorter(9.1±3.9 d vs 11.0±1.6 d,P<0.05),the days to flatus were fewer(2.8±0.8 d vs 3.5±0.7 d,P<0.05),the days to soft diet were fewer(4.2±2.4 d vs 6.2±2.0 d,P<0.05)and the intraoperative blood loss was less(103.3±80.42 mL vs 169.5±100.42 mL,P<0.05).There were no statistically significant differences between the two groups in preoperative clinical data,operation time(149.0±43.8 min vs 159.2±40.0 min),stoma rate,levels of abdominal adhesion,total cost of hospitalization,incidence of postoperative complications[8.0%(8/100)vs 15.0%(3/20)],or readmission rate within 30 days[1.0%(1/100)vs 0.00(0/20)].CONCLUSION Compared with laparotomy,laparoscopic enterectomy promotes the recovery of gastrointestinal function,shortens the postoperative hospitalization time,and does not increase the incidence of postoperative complications.Laparoscopic enterectomy combined with varieties of minimally invasive surgical techniques is a safe and acceptable therapeutic method for CD patients with enteric fistulas.

New approaches in laparoscopic surgery for colorectal diseases: The totally laparoscopic and single-incision approaches

More than 20 years have passed since the first report of laparoscopic colectomy in 1991. Thereafter, laparoscopic surgery for the management of colorectal diseases has been widely accepted as a prevailing option because of improved cosmetic outcomes, less postoperative pain, and shorter hospital stay in comparison with open surgery. To further the principle of minimally invasive surgery, two new approaches have been developed in this rapidly evolving field. The first is the totally laparoscopic approach. Currently most of standard techniques inevitably involve an abdominalincision for retrieval of the specimen and preparation for anastomosis, which might compromise the benefits of laparoscopic surgery. The totally laparoscopic approach dispenses with this incision by combining completely intraperitoneal anastomosis with retrieval of the specimen via a natural orifice, such as the anus or the vagina. Our new and reliable technique for intraperitoneal anastomosis is also described in detail in this article. The second is the single-incision approach. While three to six ports are needed in standard laparoscopic surgery, the single-incision approach uses the umbilicus as the sole access to the abdominal cavity. All of the laparoscopic procedures are performed entirely through the umbilicus, in which the surgical scar eventually becomes hidden, achieving virtually scarless surgery. This article reviews the current status of these two approaches and discusses the future of minimally invasive surgery for colorectal diseases.

Current status of minimally invasive liver surgery for cancers

Hepatocellular carcinoma(HCC)patients have chronic liver disease with functional deterioration and multicentric oncogenicity.Liver surgeries for the patients should be planned on both oncological effects and sparing liver function.In colorectal patients with post-chemotherapy liver injury and multiple bilateral tumors,handling multiple tumors in a fragile/easy-to-bleed liver is an important issue.Liver surgery for biliary tract cancers is often performed as a resection of large-volume functioning liver with extensive lymphadenectomy and bile duct resection/reconstruction.Minimally invasive liver surgery(MILS)for HCC is applied with the advantages of laparoscopic for cases of cirrhosis or repeat resections.Small anatomical resections using the Glissonian,indocyanine greenguided,and hepatic vein-guided approaches are under discussion.In many cases of colorectal liver metastases,MILS is applied combined with chemotherapy owing to its advantage of better hemostasis.Two-stage hepatectomy and indocyanine green-guided tumor identification for multiple bilateral tumors are under discussion.In the case of biliary tract cancers,MILS with extensive lymphadenectomy and bile duct resection/reconstruction are developing.A robotassisted procedure for dissection of major vessels and handling fragile livers may have advantages,and well-simulated robot-assisted procedure may decrease the difficulty for biliary tract cancers.

Current status of minimally invasive surgery for pancreatic cancer

Pancreatic cancer(PC)is the most lethal cancer among digestive system cancers.Although the only way to radically cure PC is surgical resection,complex surgical procedures and severe post-operative complications lead to high mortality.In recent years,minimally invasive surgery has become more common for PC.Minimally invasive pancreatic resection(MIPR)with the laparoscopic or robotic method has shown its superiority compared with traditional surgery.However,increasing evidence indicates that the long-term or even short-term outcomes of MIPR for PC patients remain controversial.Moreover,the indications and learning curve of MIPR require further assessment.This review aims to discuss the progress in current MIPR,analyze the specific problems and obstacles in the development of MIPR,and try to standardize MIPR procedures and improve the outcomes of MIPR.

Total mesorectal excision for mid and low rectal cancer: laparoscopic vs robotic surgery

AIM: To compare the short- and long-term outcomes of laparoscopic and robotic surgery for middle and low rectal cancer.METHODS: This is a retrospective study on a prospectively collected database containing 111 patients who underwent minimally invasive rectal resection with total mesorectal excision (TME) with curative intent between January 2008 and December 2014 (robot, n = 53; laparoscopy, n = 58). The patients all had a diagnosis of middle and low rectal adenocarcinoma with stage&#x02005;I-III disease. The median follow-up period was 37.4 mo. Perioperative results, morbidity a pathological data were evaluated and compared. The 3-year overall survival and disease-free survival rates were calculated and compared.RESULTS: Patients were comparable in terms of preoperative and demographic parameters. The median surgery time was 192 min for laparoscopic TME (L-TME) and 342 min for robotic TME (R-TME) (P &#x0003c; 0.001). There were no differences found in the rates of conversion to open surgery and morbidity. The patients who underwent laparoscopic surgery stayed in the hospital two days longer than the robotic group patients (8 d for L-TME and 6 d for R-TME, P &#x0003c; 0.001). The pathologic evaluation showed a higher number of harvested lymph nodes in the robotic group (18 for R-TME, 11 for L-TME, P &#x0003c; 0.001) and a shorter distal resection margin for laparoscopic patients (1.5 cm for L-TME, 2.5 cm for R-TME, P &#x0003c; 0.001). The three-year overall survival and disease-free survival rates were similar between groups.CONCLUSION: Both L-TME and R-TME achieved acceptable clinical and oncologic outcomes. The robotic technique showed some advantages in rectal surgery that should be validated by further studies.

Laparoscopic and endoscopic cooperative surgery for gastric tumors: Perspective for actual practice and oncological benefits

Laparoscopic and endoscopic cooperative surgery(LECS) is a surgical technique that combines laparoscopic partial gastrectomy and endoscopic submucosal dissection. LECS requires close collaboration between skilled laparoscopic surgeons and experienced endoscopists. For successful LECS, experience alone is not sufficient. Instead, familiarity with the characteristics of both laparoscopic surgery and endoscopic intervention is necessary to overcome various technical problems. LECS was developed mainly as a treatment for gastric submucosal tumors without epithelial lesions, including gastrointestinal stromal tumors(GISTs). Local gastric wall dissection without lymphadenectomy is adequate for the treatment of gastric GISTs. Compared with conventional simple wedge resection with a linear stapler, LECS can provide both optimal surgical margins and oncological benefit that result in functional preservation of the residual stomach. As technical characteristics, however, classic LECS involves intentional opening of the gastric wall, resulting in a risk of tumor dissemination with contamination by gastric juice. Therefore, several modified LECS techniques have been developed to av-oid even subtle tumor exposure. Furthermore, LECS for early gastric cancer has been attempted according tothe concept of sentinel lymph node dissection. LECS is a prospective treatment for GISTs and might become a future therapeutic option even for early gastric cancer. Interventional endoscopists and laparoscopic surgeons collaboratively explore curative resection. Simultaneous intraluminal approach with endoscopy allows surgeons to optimizes the resection area. LECS, not simple wedge resection, achieves minimally invasive treatment and allows for oncologically precise resection. We herein present detailed tips and pitfalls of LECS and discuss various technical considerations.

Minimally invasive donor hepatectomy, are we ready for prime time?

Minimally invasive surgery potentially reduces operative morbidities. However, pure laparoscopic approaches to donor hepatectomy have been limited by technical complexity and concerns over donor safety. Reducedwound donor hepatectomy, either in the form of a laparoscopic-assisted technique or by utilizing a minilaparotomy wound, i.e., hybrid approach, has been developed to bridge the transition to pure laparoscopic donor hepatectomy, offering some advantages of minimally invasive surgery. To date, pure laparoscopic donor left lateral sectionectomy has been validated for its safety and advantages and has become the standard in experienced centres. Pure laparoscopic approaches to major left and right liver donation have been reported for their technical feasibility in expert hands. Robotic-assisted donor hepatectomy also appears to be a valuable alternative to pure laparoscopic donor hepatectomy, providing additional ergonomic advantages to the surgeon. Existing reports derive from centres with tremendous experience in both laparoscopic hepatectomy and donor hepatectomy. The complexity of these procedures means an arduous transition from technical feasibility to reproducibility. Donor safety is paramount in living donor liver transplantation. Careful donor selection and adopting standardized techniques allow experienced transplant surgeons to safely accumulate experience and acquire proficiency. An international prospective registry will advance the understanding for the role and safety of pure laparoscopic donor hepatectomy.

Minimally invasive surgery in gastric cancer

Minimally invasive surgery for gastric cancer has rapidly gained popularity due to the early detection of early gastric cancer. As advances in instruments and the accumulation of laparoscopic experience increase, laparoscopic techniques are being used for less invasive but highly technical procedures. Recent evidence suggests that the short- and long-term outcomes of minimally invasive surgery for early gastric cancer and advanced gastric cancer are comparable to those of conventional open surgery. However, these results should be confirmed by large-scale multicenter prospective randomized controlled clinical trials.

Laparoscopic-endoscopic cooperative surgery for gastric submucosal tumors

AIM:To assess the feasibility,safety,and advantages of minimally invasive laparoscopic-endoscopic cooperative surgery(LECS)for gastric submucosal tumors(SMT).METHODS:We retrospectively analyzed 101 consecutive patients,who had undergone partial,proximal,or distal gastrectomy using LECS for gastric SMT at Peking Union Medical College Hospital from June 2006to April 2013.All patients were followed up by visit or telephone.Clinical data,surgical approach,pathological features such as the size,location,and pathological type of each tumor;and follow-up results were analyzed.The feasibility,safety and effectiveness of LECS for gastric SMT were evaluated,especially for patients with tumors located near the cardia or pylorus.RESULTS:The 101 patients included 43(42.6%)menand 58(57.4%)women,with mean age of 51.2±13.1 years(range,14-76 years).The most common symptom was belching.Almost all(n=97)patients underwent surgery with preservation of the cardia and pylorus,with the other four patients undergoing proximal or distal gastrectomy.The mean distance from the lesion to the cardia or pylorus was 3.4±1.3 cm,and the minimum distance from the tumor edge to the cardia was 1.5 cm.Tumor pathology included gastrointestinal stromal tumor in 78 patients,leiomyoma in 13,carcinoid tumors in three,ectopic pancreas in three,lipoma in two,glomus tumor in one,and inflammatory pseudotumor in one.Tumor size ranged from 1 to8.2 cm,with 65(64.4%)lesions<2 cm,32(31.7%)>2 cm,and four>5 cm.Sixty-six lesions(65.3%)were located in the fundus,21(20.8%)in the body,10(9.9%)in the antrum,three(3.0%)in the cardia,and one(1.0%)in the pylorus.During a median follow-up of 28 mo(range,1-69 mo),none of these patients experienced recurrence or metastasis.The three patients who underwent proximal gastrectomy experienced symptoms of regurgitation and belching.CONCLUSION:Laparoscopic-endoscopic cooperative surgery is feasible and safe for patients with gastric submucosal tumor.Endoscopic intraoperative localization and support can help preserve the cardia and pylorus during surgery.

Open surgery in the era of minimally invasive surgery

The benefits and popularity of minimally invasive surgery are undeniable around the globe.However,open surgery is necessary and learning open surgery skills is still a necessity.Open surgery allows for better exposure to the surgical field and provides tactile sensation to facilitate the stereo visual assessment to precisely remove the lesion.Open surgery is still the key to surgical training,and the skills learned from open surgeries remain crucial for unforeseen circumstances and certain conditions like emergencies,challenge cases,or patients with compromised status.

Colorectal resections for malignancy: A pilot study comparing conventional vs freehand robot-assisted laparoscopic colectomy

BACKGROUND Laparoscopic colectomy is widely accepted as a safe operation for colorectal cancer,but we have experienced resistance to the introduction of the FreeHandffrobotic camera holder to augment laparoscopic colorectal surgery.AIM To compare the initial results between conventional and FreeHandffrobot-assisted laparoscopic colectomy in Trinidad and Tobago.METHODS This was a prospective study of outcomes from all laparoscopic colectomies per-formed for colorectal carcinoma from November 29,2021 to May 30,2022.The following data were recorded:Operating time,conversions,estimated blood loss,hospitalization,morbidity,surgical resection margins and number of nodes har-vested.All data were entered into an excel database and the data were analyzed using SPSS ver 20.0.RESULTS There were 23 patients undergoing colectomies for malignant disease:8(35%)FreeHandff-assisted and 15(65%)conventional laparoscopic colectomies.There were no conversions.Operating time was significantly lower in patients under-going robot-assisted laparoscopic colectomy(95.13±9.22 vs 105.67±11.48 min;P=0.045).Otherwise,there was no difference in estimated blood loss,nodal harvest,hospitalization,morbidity or mortality.CONCLUSION The FreeHandffrobot for colectomies is safe,provides some advantages over conventional laparoscopy and does not compromise oncologic standards in the resource-poor Caribbean setting.

Review of minimally invasive pancreas surgery and opinion on its incorporation into low volume and resource poor centres

Pancreatic surgery has been one of the last areas for the application of minimally invasive surgery(MIS)because there are many factors that make laparoscopic pancreas resections difficult.The concept of service centralization has also limited expertise to a small cadre of high-volume centres in resource rich countries.However,this is not the environment that many surgeons in developing countries work in.These patients often do not have the opportunity to travel to high volume centres for care.Therefore,we sought to review the existing data on MIS for the pancreas and to discuss.In this paper,we review the evolution of MIS on the pancreas and discuss the incorporation of this service into low-volume and resource-poor countries,such as those in the Caribbean.This paper has two parts.First,we performed a literature review evaluating all studies published on laparoscopic and robotic surgery of the pancreas.The data in the Caribbean is examined and we discuss tips for incorporating this operation into resource poor hospital practice.Low pancreatic case volume in the Caribbean,and financial barriers to MIS in general,laparoscopic distal pancreatectomy,enucleation and cystogastrostomy are feasible operations to integrate in to a resource-limited healthcare environment.This is because they can be performed with minimal to no consumables and require an intermediate MIS skillset to complement an open pancreatic surgeon’s peri-operative experience.
