Hand-assisted laparoscopic splenectomy is a useful surgical treatment method for patients with excessive splenomegaly: A metaanalysis

BACKGROUND Hand-assisted laparoscopic splenectomy(HALS) can help overcome the drawbacks of laparoscopic splenectomy(LS) while maintaining its advantages.AIM To evaluate the efficacy and advantages of HALS for splenomegaly.METHODS The relevant literature was reviewed using the PubMed, EMBASE, Cochrane,Ovid Medline, and Wanfang databases to compare the clinical outcomes of HALS and LS. Odds ratios or mean differences were calculated with 95% confidence intervals for fixed-effects and random-effects models. Overall, 754 patients from16 trials who met the inclusion criteria were selected.RESULTS In pure splenectomy, blood loss volume(P < 0.001) and conversion rate(P =0.008) were significantly lower in the HALS group than in the LS group.Conversely, for splenomegaly, the operative time(P = 0.04) was shorter and blood loss volume(P < 0.001) and conversion rate(P = 0.001) were significantly lower in the HALS group than in the LS group. However, no significant difference was observed in hospital stay length, blood transfusion, time to food intake, complications, or mortality rate between the two groups. Moreover, in splenectomy and devascularization of the upper stomach(DUS), the operative time(P = 0.04) was significantly shorter and blood loss volume(P < 0.001) andconversion rate(P = 0.05) were significantly lower in the HALS + DUS group than in the LS + DUS group. However, no significant difference was observed in hospital stay length, timing of diet, and complications between the two groups.CONCLUSION HALS is an ideal surgical treatment method for splenomegaly because it can maximize the benefits for patients while maintaining the advantages of LS.

Comparison of hand-assisted laparoscopic radical gastrectomy and laparoscopic-assisted radical gastrectomy:A systematic review and meta-analysis

BACKGROUND Gastrectomy is the optimal treatment for gastric cancer.Laparoscopic-assisted gastrectomy(LAG)has been extensively employed,while hand-assisted laparoscopic gastrectomy(HALG),which is similar to LAG,remains controversial.Although HALG is popular in China,some surgeons do not accept it as a minimal-access technique.AIM To assess the safety and practicability of HALG by comparing the short-term outcomes of HALG and LAG.METHODS The electronic databases of EMBASE,PubMed,China National Knowledge Infrastructure,and Cochrane Library were thoroughly searched,and randomized controlled trials(RCTs)comparing HALG and LAG were included.The study results,including surgery time,blood loss,retrieved lymphatic nodes,incision length,time to first flatus,hospitalization duration,and all postsurgical complications,were compared between the two groups.RESULTS Five RCTs,which included 302 cases with HALG and 298 cases with LAG,were considered eligible for inclusion.Meta-analysis showed that HALG significantly reduced surgery time(P<0.01),hospital duration(P<0.01),and overall postsurgical complications(P<0.01).Additionally,HALG significantly increased the number of retrieved lymphatic nodes(P=0.01)and incision length(P<0.01)compared with LAG.The blood loss and time to first flatus were similar between the two groups(P>0.05).CONCLUSION Compared with LAG,HALG is a simpler and safer technique.Additionally,HALG should be used as a minimal-access technique,especially in technologically undeveloped areas.

Precision at scale:Machine learning revolutionizing laparoscopic surgery

In their recent study published in the World Journal of Clinical Cases,the article found that minimally invasive laparoscopic surgery under general anesthesia demonstrates superior efficacy and safety compared to traditional open surgery for early ovarian cancer patients.This editorial discusses the integration of machine learning in laparoscopic surgery,emphasizing its transformative po-tential in improving patient outcomes and surgical precision.Machine learning algorithms analyze extensive datasets to optimize procedural techniques,enhance decision-making,and personalize treatment plans.Advanced imaging modalities like augmented reality and real-time tissue classification,alongside robotic surgical systems and virtual reality simulations driven by machine learning,enhance imaging and training techniques,offering surgeons clearer visualization and precise tissue manipulation.Despite promising advancements,challenges such as data privacy,algorithm bias,and regulatory hurdles need addressing for the responsible deployment of machine learning technologies.Interdisciplinary collaborations and ongoing technological innovations promise further enha-ncement in laparoscopic surgery,fostering a future where personalized medicine and precision surgery redefine patient care.

Hand-assisted laparoscopic approach for the treatment of gastrosplenic fistula:A case report and review of the literature

Gastrosplenic fistula is a rare complication of gastric or splenic lymphoma.Here we report the case of a 48 years old man who developed a gastrosplenic fistula secondary to splenic diffuse large B-cell lymphoma,successfully managed with hand-assisted laparoscopic splenectomy and gastric wedge resection.A review of the available literature is also presented,33 cases of gastrosplenic fistula associated to gastric or splenic lymphoma were found,of which 25 were treated surgically.This case represents the first report of laparoscopic treatment of lymphoma-related gastrosplenic fistula described to our knowledge in the available literature.

Laparoscopic splenectomy for hypersplenism secondary to liver cirrhosis and portal hypertension

Since the first laparoscopic splenectomy(LS)was reported in 1991,LS has become the gold standard for the removal of normal to moderately enlarged spleens in benign conditions.Compared with open splenectomy,fewer postsurgical complications and better postoperative recovery have been observed,but LS is contraindicated for hypersplenism secondary to liver cirrhosis in many institutions owing to technical difficulties associated with splenomegaly,well-developed collateral circulation,and increased risk of bleeding.With the improvements of laparoscopic technique,the concept is changing.This article aims to give an overview of the latest development in laparoscopic splenectomy for hypersplenism secondary to liver cirrhosis and portal hypertension.Despite a lack of randomized controlled trial,the publications obtained have shown that with meticulous surgical techniques and advanced instruments,LS is a technically feasible,safe,and effective procedure for hypersplenism secondary to cirrhosis and portal hypertension and contributes to decreased blood loss,shorter hospital stay,and less impairment of liver function.It is recommended that the dilated short gastric vessels and other enlarged collateral circulation surrounding the spleen be divided with the LigaSure vessel sealing equipment,and the splenic artery and vein be transected en bloc with the application of the endovascular stapler.To support the clinical evidence,further randomized controlled trials about this topic are necessary.

Laparoscopic versus Open Splenectomy and Devascularization for Massive Splenomegaly Due to Portal Hypertension

Although the clinical benefit of laparoscopic splenectomy and devascularization（LSD） has been elaborated in many studies,its application in massive splenomegaly remains controversial.We conducted a retrospective research to assess the curative efficacy of LSD for massive splenomegaly due to portal hypertension.Forty-seven patients with massive splenomegaly due to portal hypertension were enrolled in this study,and divided into two groups.Twenty-one patients underwent open splenectomy and devascularization（OSD） from June 2010 to October 2012（OSD group）.From March 2013 to February 2015,LSD was performed on 26 patients（LSD group）.Perioperative variables were analyzed.Compared to OSD,LSD was associated with less blood loss（241.9±110.0 m L vs.319.0±139.5 m L,P〈0.05）,more rapid resumption of oral diet（2.46±0.95 days vs.3.76±1.09 days,P〈0.05）,and shorter postoperative hospital stay（5.35±1.65 days vs.7.24±1.55 days,P〈0.05）.It was concluded that for patients with massive splenomegaly due to portal hypertension,LSD is feasible and as safe as OSD.

Laparoscopic splenectomy:Current concepts

Since early 1990's,when it was inaugurally introduced,laparoscopic splenectomy has been performed with excellent results in terms of intraoperative and postoperative complications.Nowadays laparoscopic splenectomy is the approach of choice for both benign and malignant diseases of the spleen.However some contraindications still apply.The evolution of the technology has allowed though,cases which were considered to be absolute contraindications for performing a minimal invasive procedure to be treated with modified laparoscopic approaches.Moreover,the introduction of advanced laparoscopic tools for ligation resulted in less intraoperative complications.Today,laparoscopic splenectomy is considered safe,with better outcomes in comparison to open splenectomy,and the increased experience of surgeons allows operative times comparable to those of an open splenectomy.In this review we discuss the indications and the contraindications of laparoscopic splenectomy.Moreover we analyze the standard and modified surgical approaches,and we evaluate the short-term and long-term outcomes.

Prevention and Treatment of Hemorrhage during Laparoscopic Splenectomy and Devascularization for Portal Hypertension

This study was aimed to explore prevention and treatment of hemorrhage during laparoscopic splenectomy plus devascularization（LSD） for portal hypertension by modified and simplified operation. From June 2012 to June 2014, LSD was performed on 138 patients with portal hypertension. The patients were allocated into two groups： earlier stage（ES） group, in which 45 patients received traditional LSD from June 2012 to Sep. 2012; later stage（LS） group, in which 93 patients underwent modified LSD from Jan. 2013 to June 2014. Perioperative variables were compared between the two groups. Laparoscopic operations were successfully performed in all but two patients in ES group who were converted to laparotomy（total conversion rate： 1.4%）. There was no perioperative death or reoperation, and all patients recovered and were discharged from hospital with no serious complications in the six months of postoperative follow-up. The average time in the ES group was longer than that in the LS group（335.1 min vs. 201.3 min, P〈0.05）. LS group outperformed ES group in terms of blood loss（705.4 m L vs. 910.4 mL, P〈0.05）. The average operation time to oral diet intake after surgery（40.5 h vs. 50.3 h, P〈0.05） and postoperative hospital stay（7.4 d vs. 9.0 days, P〈0.05） were much less in the LS group than in the ES group. The overall complication rate（4.3 % vs. 11.1 %, P〈0.05） and conversion rate（0% vs. 4.4%, P〈0.05） were lower in the LS group than in the ES group. It was concluded that prevention and treatment of hemorrhage are the key points of LSD for portal hypertension. By creating a tunnel above the splenic pedicle and a tunnel behind the lower esophagus, the simplified and modified LSD can reduce hemorrhage and improve success of surgery dramatically, and splenomegaly and severe varices are not contraindications.

Laparoscopic distal pancreatectomy with or without splenectomy: spleen-preservation does not increase morbidity

BACKGROUND: The indications for laparoscopic spleen- preserving distal pancreatectomy (LSPDP) and its morbidity compared with laparoscopic distal pancreatectomy with splenectomy (LDPS) are ill-defined. This study aimed to share the indications for spleen-preservation and investigate the safety and outcome of LSPDP at our institution. METHODS: A retrospective review of patients who were scheduled to receive laparoscopic surgery for distal pancreatic lesions was conducted. The indications, surgical procedures, intra-operative data, and outcomes of the two procedures were collected and compared by statistical analysis. RESULTS: LDPS and LSPDP were successfully performed in 16 and 21 patients respectively, whereas they were converted to open surgery in 9 patients. There were no significant differences in age, gender, operation time, blood loss, and conversion rate between the LDPS and LSPDP groups. The mean tumor size showed an inter-group difference (5.05 vs 2.53 cm, P<0.001). There were no significant differences in complication and morbidity rates between the two groups. All patients remained alive without recurrence during a follow-up of 9 to 67 months (median 35).CONCLUSION: LSPDP has a morbidity and outcome comparable to LDPS.

Emergency laparoscopic partial splenectomy for ruptured spleen:A case report

Splenic rupture is a common consequence of blunt abdominal trauma. Emergency splenectomy is indicated when conservative management is not effective. With better understanding of the immunologic function of the spleen, surgeons have begun to perform the splenic-preserving surgery. However, it is technical challenge to perform emergency laparoscopic partial splenectomy for patient with spleen rupture. A 15-year-old male patient suffered from grade. spleen injury basing on the American association for the surgery of trauma splenic injury scale. Conservative treatment failed to success basing on the dramatically decreased hemoglobin level. During the laparoscopic exploration, we found that two individual ruptures were associated with the upper pole of spleen. An emergency laparoscopic partial splenectomy was successfully carried out. The operative time was approximate 150 min and the estimated blood loss was 200 mL. The post-operative course was uneventful and the patient was discharged on the 7th post-operative day.

Laparoscopic splenectomy for splenic littoral cell angioma

AIM:To establish the safety and feasibility of laparoscopic splenectomy(LS) for littoral cell angioma(LCA).METHODS:From September 2003 to November 2013,27 patients were diagnosed with LCA in our institution.These patients were divided into two groups based on operative procedure:LS(13 cases,Group 1) and open splenectomy(14 cases,Group 2).Data were collected retrospectively by chart review.Comparisons were performed between the two groups in terms of demographic characteristics(sex and age); operative outcomes(operative time,estimated blood loss,transfusion,and conversion); postoperative details(length of postoperative stay and complications); and follow-up outcome.RESULTS:LS was successfully carried out in all patients except one in Group 1,who required conversion to hand-assisted LS because of perisplenic adhesions.The average operative time for patients in Group 1 was significantly shorter than that in Group 2(127 ± 34 min vs 177 ± 25 min,P = 0.001).The average estimated blood loss in Group 1 was significantly lower than in Group 2(62 ± 48 m L vs 138 ± 64 m L,P < 0.01).No patient in Group 1 required a blood transfusion,whereas one in Group 2 required a transfusion.Two patients in Group 1 and four in Group 2 suffered from postoperative complications.All the complications were cured by conservative therapy.There were no deaths in our series.All patients were followed up and no recurrence or abdominal metastasis were found.CONCLUSION:LS for patients with LCA is safe and feasible,with preferable operative outcomes and longterm tumor-free survival.

Combined Laparoscopic Splenectomy and Esophagogastric Devascularization versus Open Splenectomy and Esophagogastric Devascularization for Portal Hypertension due to Liver Cirrhosis

This study was conducted to compare the feasibility,safety and effectiveness of the combined-laparoscopic splenectomy and esophagogastric devascularization(C-LSED)with open splenectomy and esophagogastric devascularization surgery(OSED)in patients with portal hypertension due to liver cirrhosis.From February 2014 to June 2018,68 patients with portal hypertension were diagnosed as having serious gastroesophageal varices and/or hypersplenism in our center.Thirty patients underwent C-LSED and 38 patients received OSED.Results and outcomes were compared retrospectively.No patients of C-LSED group required an intraoperative conversion to open surgery.Significantly shorter operating time,less blood loss,lower transfusion rates,shorter postoperative hospital stay,lower rates of complications were found in C-LSED group than in C-LSED group(P<0.05).No death and rebleeding were documented in both groups during the follow-up periods of one year Postoperative endoscopy revealed that varices in the patients of both groups were alleviated significantly from severe to mild,and in a part of cases,the varices disappeared.The final results suggest that the C-LSED technique is superior to open procedure,due to slightly invasive,simplified operative procedure,significantly shorter operating time,less intraoperative bleeding and lower post-operative complication rates.And C-LSED offers comparable long-term effects to open surgery.

Laparoscopic splenectomy for a littoral cell angioma of the spleen: Case report

A littoral cell angioma(LCA) is a primary vascular tumor of the spleen, that can have malignant potential and may present association with other malignancies. This is a case of LCA that was discovered incidentally in a 79-year-old woman who presented with a polycythemia at the time of consultation. The neoplasm was evaluated by ultrasound and computed tomography. The patient underwent a splenectomy that revealed LCA by pathological evaluation. The post-operative outcome was favorable with no complications or recurrent disease. This case presentation, clinical, radiographic, and pathological features of an uncommon splenic tumor can be studied in order to advance our knowledge in our understanding of LCA.

Comparison of perioperative outcomes between laparoscopic and open partial splenectomy in children and adolescents

BACKGROUND In order to avoid consequences of total splenectomy,partial splenectomy(PS)is increasingly reported.The purpose of this study was to compare perioperative outcomes of laparoscopic PS(LPS)and open PS(OPS)in children and adolescents.AIM To compare perioperative outcomes of patients with LPS and OPS.METHODS After institutional review board approval,a total of 26 patients that underwent LPS or OPS between January 2008 and July 2018 were identified from the database of our tertiary referral center.In total,10 patients had LPS,and 16 patients underwent OPS.Blood loss was calculated by Mercuriali’s formula.Pain scores,analgesic requirements and complications were assessed.The Wilcoxon rank sum test was used for comparison.To compare categorical variables,Fisher’s exact test was applied.RESULTS LPS was performed in 10 patients;16 patients had OPS.Demographics(except for body mass index and duration of follow-up),indicating primary disease,preoperative spleen size and postoperative spleen volume,perioperative hematological parameters,postoperative pain scores,analgesic requirements,adverse events according to the Clavien-Dindo classification and the comprehensive complication index,median time from operation to initiation of feeds,median time from operation to full feeds,median time from operation to mobilization and median length of hospital stay did not differ between LPS and OPS.Median(range)operative time(min)was longer in LPS compared to the OPS group[185(135-298)vs 144(112-270),respectively;P=0.048].Calculated perioperative blood loss(mL of red blood cell count)was higher in the LPS group compared to OPS[87(-45-777)vs-37(-114-553),respectively;P=0.039].CONCLUSION This is the first study that compared outcomes of LPS and OPS.Both operative approaches had comparable perioperative outcomes.LPS appears to be a viable alternative to OPS.

Current concepts of laparoscopic splenectomy in elective patients

Formerly,open splenectomy represented the conventional surgical treatment for many hematologic diseases.Currently,thanks to permanent technical development and improved skills,also laparoscopic splenectomy(LS) has become a recognized procedure in the treatment of spleen diseases,even in case of splenomegaly.A systematic review was performed with the aim of recalling the proved concepts of this surgical treatment and to browse new devices and techniques and their impact on the surgical outcome.The literature search was initially conducted in Pub Med by entering general queries related to LS.The record identified through Pub Med searching(n = 1599) wasthen screened by applying several criteria(study published in English from 1991 to 2013 with abstract available,by excluding systematic/non-systematic reviews,meta-analysis,practice guidelines,case reports,and study involving animals).The articles assessed for eligibility(n = 160) were primarily evaluated by excluding studies that did not report operative time and conversion to open surgery.For articles that treated multiport LS we included only clinical trials with patients > 20.The studies included in qualitative synthesis were 23.The search strategy carried out in Pub Med does not allow to obtain an overview of the items returned by the main queries.With this aim we replicated the search in the Web of Science TM database,only including the studies published in English in the period 1991-2013 with no other filter/selection criteria.The full records(n = 1141) and cited references returned by Web of Science TM were analyzed with the visualization of similarities(VOS) mapping technique.Maps of title/abstract text corpus and bibliographic coupling of authors obtained by applying the VOS approach were presented.If in normal-size or moderately enlarged spleens the laparoscopic approach is unquestionable,in massive splenomegaly the optimal technique remain to be determined.In this setting,prospective randomized trials to compare open vs LS are needed.Between the new techniques of LS the robotic single port splenectomy has the ability to join all the positive aspects of both techniques.Data about this topic are too initial and need to be confirmed with further studies.
