Editor's Choice - Infra-inguinal Endovascular Revascularisation and Bypass Surgery for Chronic Limb Threatening Ischaemia: a Retrospective European Multicentre Cohort Study with Propensity Score Matching.

OBJECTIVE: The aim of this study was to compare the long term efficacy of lower limb bypass with that of endovascular treatment (EVT) in patients with chronic limb threatening ischaemia (CLTI). METHODS: This retrospective, multicentre study evaluated the outcomes of patients with CLTI who underwent first time infra-inguinal bypass or EVT. The primary outcome was to compare amputation free survival (AFS) rates between the two propensity score matched groups. The secondary outcome was to compare wound healing within the first six months. Major adverse events were compared according to the type of revascularisation. RESULTS: Overall, 793 patients fulfilled the eligibility criteria, from whom 236 propensity score matched pairs were analysed. The mean follow up was 52 months. The 236 bypass procedures included 190 autogenous bypass grafts (80.5%), 151 (64.0%) of which were infrapopliteal. Among the 236 EVT procedures, the target lesion was the femoropopliteal segment in 81 patients (34.3%), the femoropopliteal and infrapopliteal segments in 101 patients (42.8%), and the infrapopliteal segment in 54 patients (22.9%). AFS was significantly better in the bypass group at five years (60.5 ± 3.6%) compared with the EVT group (35.3 ± 3.6%) (p < .001). Major amputation occurred in 61 patients (25.8%) in the bypass group and 85 patients (36.0%) in the EVT group (HR 0.66, 95% CI 0.47 - 0.92; p = .014). The probability of healing was significantly better in the bypass group at six months compared with the EVT group (p = .003). The median length of stay was shorter for the EVT group (4 days) than for the bypass group (8 days) (p = .001). Urgent re-intervention and re-admission rates were high and did not differ significantly between the groups. CONCLUSION: This study has shown that lower limb bypass surgery offered a significantly higher probability of AFS and wound healing compared with EVT in patients with CLTI.

Outcomes After Open and Endovascular Repair of Non-Ruptured True Pancreaticoduodenal and Gastroduodenal Artery Aneurysms Associated with Coeliac Artery Compression: A Multicentre Retrospective Study.

OBJECTIVE: True aneurysms of the peri-pancreatic arcade (PDAA) have been attributed to increased collateral flow related to coeliac axis (CA) occlusion by a median arcuate ligament (MAL). Although PDAA exclusion is currently recommended, simultaneous CA release and the technique to be used are debated. The aim of this retrospective multicentre study was to compare the results of open surgical repair of true non-ruptured PDAA with release or CA bypass (group A) vs. coil embolisation of PDAA and CA stenting or laparoscopic release (group B). METHODS: From January 1994 to February 2019, 57 consecutive patients (group A: 31 patients; group B: 26 patients), including 35 (61%) men (mean age 56 ± 11 years), were treated at three centres. Twenty-six patients (46%) presented with non-specific abdominal pain: 15 (48%) in group A and 11 (42%) in group B (p = .80). RESULTS: No patient died during the post-operative period. At 30 days, all PDAAs following open repair and embolisation had been treated successfully. In group A, all CAs treated by MAL release or bypass were patent. In group B, 2/12 CA stentings failed at < 48 hours, and all MAL released by laparoscopy were successful. Median length of hospital stay was significantly greater in group A than in group B (5 vs. 3 days; p = .001). In group A, all PDAAs remained excluded. In group B, three PDAA recanalisations following embolisation were treated successfully (two redo embolisations and one open surgical resection). At six years, Kaplan-Meier estimates of freedom for PDAA recanalisation were 100% in group A, and 88% ± 6% in group B (p = .082). No PDAA ruptured during follow up. In group A, all 37 CAs treated by MAL release were patent, and one aortohepatic bypass occluded. In group B, five CAs occluded: four after stenting and the other after laparoscopic MAL release with two redo stenting and three aortohepatic bypasses. Estimates of freedom from CA restenosis/occlusion were 95% ± 3% for MAL release or visceral bypass, and 60% ± 9% for CA stenting (p = .001). Two late restenoses following CA stenting were associated with PDAA recanalisation. CONCLUSION: Current data suggest that open and endovascular treatment of PDAA can be performed with excellent post-operative results in both groups. However, PDAA embolisation was associated with few midterm recanalisations and CA stenting with a significant number of early and midterm failures.

Intravascular Ultrasound-Assisted Endovascular Exclusion of Penetrating Aortic Ulcers.

BACKGROUND: Penetrating aortic ulcer (PAU) is an atherosclerotic lesion penetrating the elastic lamina and extending into the media of the aorta. It may evolve into intramural hematoma, focal dissection, pseudoaneurysm, and eventually rupture. The purpose of this study was to evaluate the effectiveness of a totally intravascular ultrasound (IVUS)-assisted endovascular exclusion of PAU. METHODS: Thirteen consecutive patients (median age 66 years) underwent IVUS-assisted endovascular exclusion of PAU. The primary end points were fluoroscopy time, radiation dose, and occurrence of type I primary endoleak. Secondary end points were postoperative mortality and morbidity, arterial access complications, postoperative length of stay in the hospital, and occurrence of type II endoleaks. RESULTS: The median fluoroscopy time was 4 min (4-5). The median radiation dose was 4.2 mGy (3.9-4.5). A proximal and distal landing zone of at least 2 cm could be obtained in all the patients. No patient presented a type I endoleak. No postoperative mortality, no morbidity, or arterial access complication was observed. The median length of postoperative stay in the hospital was 2 days (2-3). The median length of follow-up was 25 months (9.2-38.7). One late type II endoleak was observed (7.7%), because of reflux from the intercostal arteries, without the need for additional treatment. CONCLUSIONS: IVUS-assisted endovascular treatment of PAU allows durable exclusion of PAU with a short fluoroscopy time and no need for injection of contrast media. Further series are needed to confirm the results of this preliminary study.

Standard versus eversion-modified double-staple technique for low colorectal anastomoses after resection of rectal cancer.

PURPOSE: The double-staple technique, performed as either the standard procedure or after eversion of the rectal stump, is a well-established method of performing low colorectal anastomoses following the resection of rectal cancer. Eversion of the tumor-bearing ano-rectal stump was proposed to allow the linear stapler to be fired at a safe distance of clearance from the tumor. We conducted this study to compare the results of the standard versus the eversion-modified double-staple technique. METHODS: The subjects of this retrospective study were 753 consecutive patients who underwent low stapled colorectal anastomosis after resection of rectal cancer. The patients were divided into two groups according to the method of anastomosis used: Group A comprised 165 patients (22%) treated with the modified eversion technique and group B comprised 588 patients (78%) treated with the standard technique. The primary endpoints of the study were postoperative mortality, surgery-related morbidity, the number of sampled lymph nodes in the mesorectum, and late disease-related survival. RESULTS: Postoperative mortality was 1.2% in group A and 1.7% in group B (p = 0.66). Postoperative morbidity was 12% in group A and 11% in group B (p = 0.75). The mean number of sampled lymph nodes in the mesorectum was 23 (range 17-27) in group A and 24 (range 19-29) in group B (p = 0.06). The 5-year disease-related survival was 73% in group A and 74% in group B (p = 0.75). CONCLUSION: The standard and eversion-modified double-staple techniques yield comparable results.

Long-term results of polytetrafluoroethylene versus saphenous vein repair of degenerative carotid artery aneurysm.

OBJECTIVE: To compare the results of polytetrafluoroethylene (PTFE) and great saphenous vein (GSV) bypass after resection of a degenerative aneurysm of the carotid artery. METHODS: From January 1994 to November 2017, 37 patients (27 men) with a mean age of 58 years (range, 39-82 years) with a degenerative aneurysm of the carotid artery (median diameter, 28 mm; range, 19-42 mm), underwent resection of the aneurysm followed by a bypass with either a GSV (n = 10) or a PTFE prosthesis (n = 27). Although 31 patients were asymptomatic, 6 patients were symptomatic: transient ischemic attack (n = 4), minor stroke (n = 1), and compression of the hypoglossal nerve (n = 1). The preoperative workup included duplex ultrasound examination of the arteries to the head, and angiography or computed tomography angiography. All patients were operated under general anesthesia and six were intubated through the nose. Sixteen patients were monitored through transcutaneous oximetry. No shunt was used in this series. In 10 patients receiving a PTFE graft, the external carotid artery was implanted in the prosthesis. Mean follow-up was 16.9 ± 2 years (95% confidence interval, 14.5-19.3 years). Primary end points were the 30-day combined stroke/death rate, graft infection, late graft patency, and late stroke-free survival. Secondary end points were cranial nerve injury and length of postoperative hospital stay. RESULTS: Postoperative mortality was nil in both groups. One postoperative stroke was observed in the PTFE group, whereas none occurred in the GSV group (P = .84). No graft infection was observed in either group. At 10 years, survival in the GSV group was 80 ± 12%, and survival in the PTFE group was 76 ± 8% (log-rank [Mantel-Cox], P = .85). In the GSV group, graft patency at 7 and 10 years was 85 ± 13%. In the PTFE group B, graft patency was 100% (log-rank [Mantel-Cox], P = .12). No late stroke was observed. Two transient cranial nerve injuries were observed in the GSV group (20%) and two in the PTFE group (8%) (P = .97). Length of hospital stay was comparable in both groups (GSV group, 6 days; PTFE group, 5 days; P = .12). CONCLUSIONS: This study suggests that, after resection of a degenerative aneurysm of the carotid artery, bypass with a PTFE prosthesis gives comparable results to those obtained with the GSV. We recommend sparing the GSV and instead using a PTFE prosthesis in patients with a degenerative aneurysm of the carotid artery.

Endovascular Exclusion of Abdominal Aortic Aneurysms and Simultaneous Resection of Colorectal Cancer.

BACKGROUND: No consensus exists on the optimal strategy for treatment of abdominal aortic aneurysm (AAA) associated with colorectal cancer (CRC). The purpose of this study was to evaluate the results of endovascular treatment of AAA with simultaneous resection of CRC. METHODS: Twenty-two consecutive patients presenting with AAA associated with a CRC were treated by endovascular AAA exclusion and simultaneous CRC resection. Median diameter of the aneurysm was 6.5 cm (range, 4.8-8 cm). Two patients (9%) had grade I cancer, 5 patients (23%) grade II, 13 patients (59%) grade III, and 2 patients (9%) grade IV. The 2 surgical procedures were performed under the same general anesthesia. Aneurysm exclusion was achieved using an infrarenal aorto-bi-iliac endoprosthesis (13 patients) and using an aorto-bi-iliac endoprosthesis with suprarenal fixation (9 patients), with 1 patient receiving bilateral renal chimney stent implantation. In all cases, vascularization of the hypogastric arteries was preserved. After AAA exclusion, colic resection was carried out by laparotomy with right colectomy (7 patients) and anterior rectocolic resection (15 patients). In all patients, AAA exclusion was controlled by a computed tomographic angioscan (CTA) at 1 month and duplex ultrasound every 6 months, and at some later stage, it was through inclusion of CTA as part of oncology surveillance. The mean duration of follow-up was 42 months (10-120 months). The primary endpoint was composite and regrouped any death occurring during the first 30 days after procedures, any type I endoleak, any aortic reintervention, and any AAA-related mortality. RESULTS: No patient died during the first 30 postoperative days, and no patient was lost to follow-up. No aortic endoprosthesis infection and no type I endoleak were observed. Five endoleaks arising from the lumbar arteries (n = 4) or from the inferior mesenteric artery (n = 1) were identified. As they were not associated with an increase of the AAA diameter >5 mm, they were not treated. 1 colic anastomotic leak and 2 incisional abscesses were successfully cured by local care only. Nine patients (41%) died of cancer evolution during the follow-up period. CONCLUSIONS: In this series, treatment of AAA and CRC during the same operative session yields results comparable to those observed when surgery is performed in 2 distinct operative sessions. Synchronous treatment reduced waiting time of colic resection. It may also shorten total hospitalization duration, although this last hypothesis is not supported by comparison with a control group.

Results of Infrageniculate Bypasses Using the Profunda Femoris Artery as Inflow Source.

BACKGROUND: When the common femoral artery is not accessible for infrainguinal bypass grafting, the profunda femoris artery (PFA) can be a valuable alternative inflow source for distal arterial revascularization. The purpose of this retrospective study was to evaluate the results of infrageniculate bypass grafting via the PFA as inflow source for critical limb ischemia. METHODS: Between 1994 and 2016, 68 patients, 51 men of a mean age of 74 years, underwent an infrageniculate arterial bypass grafting for critical limb ischemia, using the PFA as inflow site. PFA was exposed at the Scarpa's triangle in 38 patients (56%) and at its medio-crural segment in 30 patients (44%). The distal anastomosis was performed on the infragenicular popliteal artery in 33 patients (48%), the peroneal artery in 14 patients (20%), the tibioperoneal trunk in 8 patients (12%), the posterior tibial artery in 8 patients (12%), and the dorsalis pedis artery in 5 patients (8%). The graft material consisted of a reversed great saphenous vein (GSV) in 62 patients (91%) and a 6-mm polytetrafluoroethylene graft in 6 patients (9%). The median duration of follow-up was 51 months (range, 6-72 months). As main results, postoperative mortality and morbidity, overall late patients' survival, primary grafts' patency, and limb salvage rate were considered. RESULTS: Operative mortality and morbidity were 3% and 4%, respectively. Overall patients' survival, primary patency and limb salvage rate, at 36 and 60 months were, respectively, 62% and 53%, 66% and 59%, and 92% and 77%. CONCLUSIONS: The PFA, both exposed at the Scarpa's triangle and at mid-thigh, is an excellent inflow source for infrageniculate revascularizations. It should remain an important part of the technical armamentarium of vascular surgeons, even in the endovascular era.

Percutaneous Retrograde Trans-Gluteal Embolization of Type 2 Endoleak Causing Iliac Aneurysm Enlargement after Endovascular Repair: Case Report and Literature Review.

Late type II endoleaks (T2ELs) arising from the internal iliac artery (IIA) may present during follow-up after endovascular aortic repair (EVAR) of aortoiliac aneurysm and may warrant embolization if enlargement of the aneurysmal sac is demonstrated. When coverage of the IIA ostium has been made due to extensive iliac disease, access options can be challenging. Different treatment options have been reported over recent years, and a careful selection of the best one must be made based on the characteristics of each case. The present study reports a simple and reproducible sheathless percutaneous superior gluteal artery (SGA) access and provides a discussion based on a review of the existing literature on this topic.

Laparoscopy-assisted vs open total gastrectomy with D2 lymphadenectomy for advanced gastric cancer: results of a retrospective, multicenter study.

The aim of this study was to retrospectively compare the results of laparoscopy-assisted total gastrectomy (LATG) with those of open total gastrectomy (OTG) for advanced gastric cancer. Patients undergoing total gastrectomy for a T4a, N0-3a-b, M0 gastric adenocarcinoma were divided into two groups. Patients in group A (n = 122) underwent LAG, whereas patients in group B (n = 109) underwent OTG. Mean length of follow-up was 39 months. Primary study's endpoints were postoperative mortality and morbidity, overall late survival (OS) and disease-free survival (DFS). Secondary endpoints were the number of retrieved lymph nodes, operating time, intraoperative blood loss, postoperative length of stay (LOS) and the incidence of local recurrence. Twenty-four patients in group A (19.6%) required conversion into OTG. Postoperative mortality was absent in both groups. Postoperative morbidity was 19% in group A and 11% in group B [p = 0.19]. OS was 34% in group A and 42% in group B [p = 0.21]. DFS was 29% in group A and 33% in group B [p = 0.49]. Mean number of retrieved lymph nodes was 29 in group A and 34 in group B [p < 0.01]. Mean intraoperative blood loss was 230 ml in group A and 180 ml in group B [p = 0.02]. Mean postoperative LOS was 9 days in group A and 11 days in group B [p = 0.09]. Local recurrence was 19% in group A and 13% in group B [p = 0.20]. For advanced gastric cancer, OTG favorably compares with LATG.

Surgeon-Pathologist Team Approach Dramatically Affects Lymph Nodes Detection and Improves Patients' Short-Term Outcome.

The downstaging of gastric cancer has recently gained particular attention in the field of gastric cancer surgery. The phenomenon is mainly due to an inappropriate sampling of lymph nodes during standard lymphadenectomy. Hence, collection of the maximum number of lymph nodes is a critical factor affecting the outcome of patients. None of the techniques proposed so far have demonstrated a real efficiency in increasing the number of identified lymph nodes. To harvest the maximum number of lymph nodes, we designed a protocol for on-site macroscopic evaluation and sampling of lymph nodes according to the Japanese Gastric Cancer Association protocol. The procedure was carried out by a surgeon/pathologist team in the operating room. We enrolled one hundred patients, 50 of whom belonged to the study group and 50 to a control group. The study group included patients who underwent lymph node dissection following the proposed protocol; the control group encompassed patients undergoing standard procedures for sampling. We compared the number and maximum diameter of lymph nodes collected in both groups, as well as some postoperative variables, the 30-day mortality and the overall survival. In the study group, the mean number of lymph nodes harvested was higher than the control one (p = 0.001). Moreover, by applying the proposed technique, we sampled lymph nodes with a very small diameter, some of which were metastatic. Noticeably, no difference in terms of postoperative course was identified between the two groups, again supporting the feasibility of an extended lymphadenectomy. By comparing the prognosis of patients, a better overall survival (p = 0.03) was detected in the study group; however, to date, no long-term follow-up is available. Interestingly, patients with metastasis in node stations number 8, 9, 11 or with skip metastasis, experienced a worse outcome and died. Based on our preliminary results, the pathologist/surgeon team approach seems to be a reliable option, despite of a slight increase in sfaff workload and technical cost. It allows for the harvesting of a larger number of lymph nodes and improves the outcome of the patients thanks to more precise staging and therapy. Nevertheless, since a higher number of patients are necessary to confirm our findings and assess the impact of this technique on oncological outcome, our study could serve as a proof-of-concept for a larger, multicentric collaboration.

Results of resection of carotid body tumors with and without lymphnodes' dissection.

BACKGROUND: Carotid body tumor (CBT) is a slow-growing tumor arising from the carotid body, a chemoceptor organ lying behind the carotid artery bifurcation. Although rarely, metastases can occur distally through the hematogenous route and through the lymphatic route.to the cervical lymphnodes. The purpose of this study was to assess whether lymphnodes' resection should systematically be associated with the primary resection of a CBT. METHODS: A retrospective analysis of 82 patients, 52 women of a mean age of 42 years undergoing resection of 88 CBT from 1994 to 2019. CBT were divided into 2 groups. Tumors in group A (n = 23, 26%) were treated by resection of the mass followed by a selective latero-cervical lymphadenectomy; tumors in group B (n = 65, 74%) underwent isolated resection of the mass. The study's primary endpoints were postoperative stroke/mortality rate, disease-specific survival and rate of local and distant recurrence of the disease. RESULTS: Postoperative stroke-mortality rate was nil. One patient in group A (4.3%) presented a minor weakness of the contralateral arm, completely regressive within 12 h. One patient in group B (1.5%) died of liver and lung metastases 51 months after operation, no patient died of recurrent disease in group A (p = .62). No nodal recurrence was observed in group A, whereas one patient in group B (1.5%) presented nodal recurrence 39 months after primary tumor resection (p = .58) CONCLUSION: Selective lymphadenectomy associated with CBT resection does not increase the overall long-term survival and cannot be considered mandatory. It may help to better define the stage of the disease and to plan eventual adjuvant treatments.

Simultaneous Laparoscopic Cholecystectomy and Endovascular Infrarenal Aortic Aneurysm Repair.

Background/Aim: With the increasing use of endovascular aneurysm repair (EVAR) and the availability of laparoscopic cholecystectomy (LC) for treating abdominal aortic aneurysms (AAA) and cholelithiasis, respectively, the association between these elective treatments is not yet well-defined. Thus, this study aimed to evaluate the results of elective and simultaneous EVAR and LC. Methods: Thirteen patients (mean age, 72 years) with concomitant large and asymptomatic AAA and asymptomatic cholelithiasis underwent simultaneous EVAR and LC. Results: Post-operative mortality was absent, and the morbidity rate was 7%. The mean total duration of the procedure was 142 min. The mean duration of fluoroscopy was 19 min, and the mean radiation dose was 65 mGy. The mean amount of iodinated contrast injected was 49 mL. The timing of oral fluid intake was 28 h (range, 24-48 h) and that of the oral low-fat diet was 53 h (range, 48-72 h). No patient presented with an aortic graft infection during the entire follow-up period (mean duration, 41 months). The mean length of post-operative hospital stay was 6 days (range, 5-8 days). Late survival was 85%, and the exclusion of AAA was 100%. Conclusion: Simultaneous EVAR and LC can be performed safely, allowing effective and durable treatment under both AAA and cholelithiasis conditions.

Outcome of Surgical Resection and Chemotherapy Versus Chemotherapy Alone for the Treatment of Isolated Primary Adrenal Lymphoma: A Retrospective Cohort Study of 16 Consecutive Patients.

BACKGROUND/AIM: Primary adrenal lymphoma (PAL) is rare and aggressive. The aim of this retrospective study was to compare the results of surgery and chemotherapy compared to chemotherapy alone for the treatment of this condition. PATIENTS AND METHODS: Sixteen patients, 10 men and 6 women of a median age of 63 years (IQR=56-70.5 years), admitted for the treatment of PAL, were retrospectively reviewed. Six patients (37.5%) underwent surgical resection of the mass followed by CHOP (cyclophosphamide, doxorubicin, vincristine, bleomycin and prednisone) - based chemotherapy (Group A). Ten patients (62.5%) underwent chemotherapy alone, consisting of CHOP alone in one case and Rituximab-CHOP (R-CHOP) in 9 cases (Group B). As primary study endpoints of the study, overall survival (OS) and progression-free survival (PFS) were considered. RESULTS: At two years follow-up, OS was 50% in Group A and 60% in group B (p=0.69). The PFS was 50% in group A and 30% in group B (p=0.42). CONCLUSION: PAL exhibits overall a dismal prognosis. Chemotherapy remains the most appropriate treatment, although unable to ensure long-term survival. Surgery combined with chemotherapy is ineffective in improving survival and may, at best, have a limited role in relieving the pain related to the local mass effect.

Results of Adrenalectomy for Isolated, Metachronous Metastasis of Breast Cancer: A Retrospective Cohort Study.

Background and Aim: Metachronous, isolated adrenal metastases from breast cancer are extremely rare. The aim of this study was to evaluate the results of adrenalectomy as a treatment of this uncommon condition. Methods: Twelve female patients (median age: 68 years) underwent 13 adrenalectomies for isolated, metachronous metastases of breast cancer. Ten resections were performed thorugh open surgery and two were preformed through a laparoscopic approach. As main study endpoints, postoperative mortality, postoperative morbidity and disease-free survival were considered. Median length of follow-up was 40 months. Results: Postoperative mortality was absent. Postoperative morbidity was 17%: one patient presented a postoperative pneumothorax requiring drainage and one patient required re-hospitalization 8 days after contralateral adrenalectomy for electrolyte imbalance. Two patients died of recurrent metastatic disease, 28 and 33 months respectively after adrenalectomy. One patient remained alive with hepatic metastases at 32 months from resection of adrenal recurrence. All in all, disease-free survival at 48 months was 75%. Conclusions: Adrenalectomy for metachronous, isolated metastases of breast cancer can be performed with no postoperative mortality and minimal postoperative morbidity, enabling good long-term disease-free survival.

Resection for Internal Jugular Vein Thrombosis and Cervical Lymph Nodes' Involvement from Gastric Cancer.

BACKGROUND/AIM: Thrombosis internal jugular vein (IJV) with cervical adenopathy, as first manifestation of gastric cancer is rare. We aimed to compare resection of the cervical mass followed by gastrectomy with gastrectomy alone. PATIENTS AND METHODS: Nine patients presenting thrombosis of the IJV for gastric carcinoma were divided into two groups. Patients in group A (n=3) underwent anticoagulation treatment, gastrectomy and adjuvant treatment. Patients in group B (n=6) underwent resection of the cervical mass and internal jugular vein (radical neck dissection), and then gastrectomy and adjuvant treatment. RESULTS: Median survival was 15.3 months in group A (range=11-19 months) and 31.2 months in group B (range=7-44 months) (p=0.11). Late cervical recurrence/complications occurred in 2 patients in group A and none in group B (p=0.02). CONCLUSION: Resection of thrombosed IJV and satellite lymph nodes, due to a primary gastric cancer may contribute to diagnosis of the disease, limit pulmonary embolic complications and improve quality of life.

Results of Standard Stapler Closure of Pancreatic Remnant After Distal Spleno-Pancreatectomy for Adenocarcinoma.

Background/Aim: The purpose of this study was to evaluate the results of stapled closure of the pancreatic remnant after cold-knife section of the pancreatic isthmus and distal pancreatectomy for adenocarcinoma. Methods: A retrospective evaluation of 57 consecutive patients undergoing distal spleno-pancreatectomy for adenocarcinoma was performed. The pancreatic isthmus was systematically straight-sectioned with a cold knife, and the remnant was stapled close without additional stitches or adjuncts. The study's main endpoints were postoperative mortality, the occurrence of a pancreatic fistula, the need for a re-operation, the postoperative length of stay in the hospital, the rate of re-admission, and late survival. Results: Postoperative mortality was absent. Seventeen patients (29.8%) presented a pancreatic fistula of grade A in seven cases (41.2%), grade B in eight cases (47.1%), and grade C in two cases (11.8%). Re-operation was required in the two patients (3.5%) with grade C fistula in order to drain an intra-abdominal abscess. The mean postoperative length of stay in the hospital was 15 days (range, 6-62 days). No patient required re-admission. Twenty-nine patients (50.8%) were alive and free from disease, respectively, 12 patients (21.1%) at 12 months, 13 patients (22.8%) at 60 months, and four patients (7.0%) at 120 months from the operation. The remaining patients died of metastatic disease 9-37 months from the operation. Lastly, disease-related mortality was 49.1%. Conclusion: Stapler closure of the pancreatic remnant allows good postoperative results, limiting the formation of pancreatic fistula to the lower limit of its overall reported incidence.

Laparoscopic lavage/drainage as a bridge treatment for perforated diverticulitis with purulent peritonitis associated with an abdominal aortic aneurysm A retrospective case-control study.

AIM: Laparoscopic lavage /drainage (LALA) or surgical resection are both methods of treatment for perforated diverticulitis with purulent peritonitis (Hinchey Stage III). In case of associated abdominal aortic aneurysm (AAA), laparoscopic lavage/drainage could be an interesting bridge option to treat sepsis before endovascular exclusion of the aneurysm and resection of the sigmoid. We performed LALA as a bridge treatment of peritonitis before elective, staged endovascular exclusion of the aneurysm (EE) and elective resection of the colon. MATERIAL AND METHODS: Seven patients presenting a perforated diverticulitis with purulent peritonitis (Hinchey III), associated with an uncomplicated AAA of a mean diameter of 6 cm, underwent LALA followed by staged EE and resection. They were retrospectively reviewed for a case-control study. The mean length of follow-up after completing all the procedures was 28 months. Primary endpoints were mortality and morbidity of each procedure, complications related to each procedure and to the untreated disease in the interval between each one of them, late outcome and complications related to each treatment method. As secondary endpoints, the mean length of surgery for resection, of stay in the hospital, of the interval between each procedure, and of time required for the treatment of both the diseases were considered. RESULTS: Postoperative mortality was absent. Morbidity consisted of a sigmoido-vescical fistula 18 days after resolution of peritonitis and sepsis, not hindering EE,and a delayed healing of the surgical wound for access to the common femoral artery (28.6%). No complications of untreated disease in the interval between each procedure were observed. No late complications of both diseases occurred. The mean interval between LALA and EE,and between EE and resection was, respectively, 19 days and 18 days. Both the diseases were treated within a mean delay of 37 days after LALA (range, 24-61 days). CONCLUSIONS: LALA, as a bridge treatment, before EE and resection, in patients presenting a perforated diverticulitis with purulent peritonitis, associated with an uncomplicated AAA, may be an effective treatment option. KEY WORDS: Perforated diverticulitis, Purulent peritonitis, Abdominal aortic aneurysm.

Laparoscopic modified double stapling technique with transanal resection for low anterior resection of rectal cancer.

BACKGROUND AND AIM: Anterior resection of the rectum with a total mesorectal excision is the standard surgical technique for the treatment of rectal cancer. Laparoscopic low anterior resection (LALAR) is an alternative to open surgical approach and was validated in diverse randomized control trials to be as safe and oncologically effective. That said, confronting a low rectal tumor in an obese patient with a narrow pelvis can be technically challenging even for the most expert surgeon. METHODS: We propose a modified double stapling technique with transanal eversion and staple resection of the rectal stump. RESULTS: We applied the above technique in 3 patients with a dubious distal resection margin due to patient/tumor characteristics. The mean length of operation was 272 minutes and a R0 resection with a mean number of 16 nodes could be obtained in all the patients. No recurrence occurred during a follow-up of 28 months. CONCLUSIONS: We conclude that this technique is a feasible, safe and valid adjunct to the double staple technique whenever intraabdominal application of the linear staple is difficult or unsafe. KEY WORDS: Colorectal cancer, Laparoscopic anterior resection, Double, Low colorectal anastomosis, Stapling technique.

Open surgery for aneurysms of the splenic artery at the hilum of the spleen: Report of three cases.

INTRODUCTION: Aneurysms of the splenic artery (SAA) located at the hilum of the spleen are not well fit for endovascular or laparoscopic treatment. Open surgery may still be the best option of treatment. PRESENTATION OF CASES: We report the cases of 3 female patients of a mean age of 59 years (range, 45-68 years) with a hilar (n = 2) or parahilar (n = 1) SAA undergoing successful open surgical resection, through a short left subcostal access. Recovery was uneventful and mean, postoperative length of stay was 4 days (range, 3-5 days). DISCUSSION: Results of this report support surgical resection and splenectomy for the treatment of SAA located at the hilum of the spleen. For this particular location endovascular treatment may not be advised, as coil embolization can be followed by a massive splenic infarction precipitating the need for splenectomy, due to the exclusion of backflow from the left gastroepiploic artery through the short gastric vessels. As well, endovascular exclusion through insertion of an endograft may not be feasible due to the absence of a distal landing zone, as stent grafting requires a normal caliber artery of sufficient length on each side of the aneurysm. CONCLUSION: Surgical excision and splenectomy, through a short subcostal incision, remains a viable option of treatment for hilar SAA.
