New clinical application of indocyanine green in fluorescence-guided laparoscopic lymph-node biopsy in case of lymphoma. Preliminary results on a case series.

BACKGROUND: Indocyanine Green (ICG) fluorescence-guided surgery is widely used for intraoperative visualization of lymphatic structures. To date, there are no reports indicating this dye being used in lymph node biopsies for suspected or relapsed lymphoma. METHODS: Between October 2021 and June 2022, 12 patients underwent a fluorescence-guided laparoscopic lymph node biopsy (FGLLB) using ICG. The following was retrospectively evaluated: the dosage of ICG, the injection site, the number of patients where fluorescence was obtained after ICG administration, and additionally, the parameters indicating the outcome of the surgical procedure. RESULTS: The median duration of the surgery was 90 min. A laparotomy conversion was required in one case due to bleeding. Fluorescence was obtained in 10/12 (83.3%) patients by means of subcutaneous/perilesional injection in six of the patients, and intravenously in the other four. Hospitalization had a mean duration of three days. There were no major postoperative complications. FGLLB was used in seven patients to follow lymphoproliferative disease progression, and in five patients to establish a diagnosis. In all cases, FGLLB provided the information necessary for the correct diagnosis. CONCLUSIONS: Fluorescence with ICG offers a simple and safe method for detecting pathological lymph nodes. FGLLB in suspected intra-abdominal lymphoma can largely benefit from this new opportunity which has not yet been tested to date. Further studies with large case series are needed to confirm its efficacy.

SECCA procedure for anal incontinence and antibiotic treatment: a case report of anal abscess.

BACKGROUND: Fecal Incontinence (FI) can seriously affect quality of life. The treatment of fecal incontinence starts conservatively but in case of failure, different surgical approaches may be proposed to the patient. Recently several not invasive approaches have been developed. One of these is the radiofrequency (RF) energy application to the internal anal sphincter. CASE PRESENTATION: We report a rare case of an anal abscess related to a SECCA procedure in a 66-year-old woman affected by gas and FI for twenty years. CONCLUSIONS: The complications post-SECCA procedure reported in literature are generally not serious and often self-limited, such as bleeding or anal pain. This is a case of an anal abscess. We suggest that this finding could consolidate the importance of administering antibiotic therapy to patients and to run a full course of at least 6 days rather than a short-term (24 h) therapy, with the aim to minimize the incidence of this complication.

Radiofrequency Procedure (SECCA®) for Fecal Incontinence: One-Year Experience.

INTRODUCTION: Radiofrequency is a treatment option for patients suffering from fecal incontinence. OBJECTIVE: To assess the one-year follow-up results following the radiofrequency procedure for fecal incontinence. DESIGN: Prospective, single-center, observational study. MATERIALS AND METHODS: Twenty-one patients underwent the SECCA® radiofrequency procedure, 19 of who completed the one-year of follow-up (Cleveland Clinic Florida Fecal Incontinence score, Fecal Incontinence Quality of Life Scale (FIQoL), anorectal manometry, and endoanal ultrasound). MAIN OUTCOME MEASURES: Any change in the Fecal Incontinence Score or Fecal Incontinence Quality of Life scales post SECCA® radiofrequency procedure. RESULTS: The mean Fecal Incontinence Score significantly improved at three months' follow-up from 14.5 prior to treatment to 11.9 post-treatment, and was maintained at six months (12). A slight decrease was observed at one year (12.9), which had no impact on the global satisfaction. During the same period, only 1/4 subsets of the Fecal Incontinence Quality of Life score improved. Manometry and endoanal ultrasound did not show significant changes post procedure. LIMITATIONS: Limited number of patients. CONCLUSIONS: Radiofrequency is a valid treatment option for patients with mild-to-moderate fecal incontinence. This treatment has demonstrated clinically significant improvements in symptoms, as demonstrated by statistically significant reductions in the Fecal Incontinence Score as well as significant improvements in Fecal Incontinence Quality of Life scores at six months, with a slight, though not clinically significant, decrease at one year follow-up.

Stapled Mesh Reinforcement Technique (SMART) to Prevent Parastomal Hernias: Our Initial Experience and Review of the Literature.

Parastomal hernia is one of the most common stoma related complication, with the correlated risk of incarceration, obstruction, and strangulation. The incidence is high (30-50%) and depends on the length of follow up. Different surgical options for repairing are defective with a 25-70% failure and recurrence rate. Prevention of parastomal hernia with mesh reinforcement seems to be effective. Three available trials are recruiting patients: Prism (with matrix porcine prothesis), Prevent (with preperitoneal polypropylene mesh), and the stapled polypropylene mesh stoma reinforcement technique (SMART). We performed the SMART procedure in six patients undergoing definitive colostomy. Our cases show that the procedure is rapid (duration range 15-20 minutes), cost effective (500 euro), and safe (in our experience, there are no post-surgical complications that are procedure-related). A long term follow-up and a higher number of patients will give us confirmation of the initial hopeful results.

The procedure outcome of laparoscopic resection for 'small' hepatocellular carcinoma is comparable to vlaparoscopic radiofrequency ablation.

BACKGROUND: The aim of this study was to compare the effectiveness of laparoscopic liver resection (LLR) and laparoscopic radiofrequency ablation (LRFA) in the treatment of small nodular hepatocellular carcinoma (HCC). PATIENTS AND METHODS: We enrolled 50 cirrhotic patients with similar baseline characteristics that underwent LLR (n = 26) or LRFA (n = 24), in both cases with intraoperative ultrasonography. Operative and peri-operative data were retrospectively evaluated. RESULTS: LLR included anatomic resection in eight cases and non-anatomic resection in 18. In LRFA patients, a thermoablation of 62 nodules was achieved. Between LLR and LRFA groups, a significant difference was found both for median diameters of treated HCC nodules (30 vs. 17.1 mm; P < 0.001) and the number of treated nodules/patient (1.29 ± 0.62 vs. 2.65 ± 1.55; P < 0.001). A conversion to laparotomy occurred in two LLR patient (7.7%) for bleeding. No deaths occurred in both groups. Morbidity rates were 26.9% in the LLR group versus 16.6% in the LRFA group (P = 0.501). Hospital stay in the LLR and LRFA group was 8.30 ± 6.52 and 6.52 ± 2.69 days, respectively (P = 0.022). The surgical margin was free of tumour cells in all LLR patients, with a margin <5 mm in only one case. In the LRFA group, a complete response was achieved in 90.3% of thermoablated HCC nodules at the 1-month post-treatment computed tomography evaluation. CONCLUSIONS: LLR for small peripheral HCC in patients with chronic liver disease represents a valid alternative to LRFA in terms of patient toleration, surgical outcome of the procedure, and short-term morbidity.

Fluorescence-guided laparoscopic lymph node biopsy for lymphoma: the FLABILY study.

To date, no reports have indicated laparoscopic lymph node biopsies using Indocyanine green (ICG) in cases of lymphoproliferative disease. Preliminary data of patients undergoing fluorescence-guided laparoscopic lymph node biopsy (FGLLB) using ICG was retrospectively analysed from the multicentre registry FLABILY study. Between June 2022 and February 2024, 50 patients underwent FGLLB. The surgical biopsy aimed to re-stage lymphoproliferative disease for 25 patients and to establish a diagnosis in 25 patients. The median duration of the procedure was 65 ± 26.5 min. All the procedures were performed laparoscopically. One surgical conversion occurred due to bleeding. Median length of hospitalization was 1 ± 1.7 days. Two unrelated complications occurred in the immediate postoperative course. ICG was administrated preoperatively by means of an inguinal, perilesional, or intravenous injection according to the anatomical sites of the biopsy. Fluorescence was obtained in 43/50 (86%) of patients. A significant difference was highlighted in the appearance of fluorescence in sub-mesocolic lymph nodes compared to supra-mesocolic and mesenteric lymph nodes (41/49 (83.6%) vs. 13/22 (59%), p = 0,012). In 98% of cases, FGLLB provided the information necessary for the correct diagnosis. Fluorescence with ICG offers a simple and safe method for detecting pathological lymph nodes. FGLLB in suspected intra-abdominal lymphoma can largely benefit from this new opportunity which, to date, has not yet been tested. Further studies with a larger case series are needed to confirm its efficacy.

Pediatric primary spontaneous pneumothorax: a comparison of treatment at pediatric surgery vs. thoracic surgery departments.

Management of pediatric Primary Spontaneous Pneumothorax (PSP) is controversial and based on guidelines on adults. Therapeutic strategies include: observation, needle aspiration, chest drain, or surgery. We aimed to assess: i) differences in the management of PSP in pediatric vs. adult departments; ii) risk of recurrence associated to each therapeutic choice; iii) management of "large" pneumothorax (i.e. >3cm at the apex on chest X-Ray); iv) role of CT scan in addressing the treatment. We reviewed all PSP treated at Pediatric Surgery Unit (PSU) and Thoracic Surgery Unit for adults (TSU) in a 10-year period (2011 to 2020). We included a total of 42 PSP: 30/42 1st episodes and 12/42 recurrences. Among the 30/42 1st episodes, 15/30 were managed in the PSU and 15/30 in the TSU. Observation was significantly most common among PSU patients (9/15, 60%) vs. TSU cases (1/15, 6.7%; p=0.005]. Chest drain placement was reduced in PSU (3/15, 20%) vs. TSU (12/15, 80%; p=0.002). Observational was associated with a reduced risk of recurrence (0/10, 0%) compared to chest drain (7/15, 46.7%; p=0.01). Management of 20/42 "large" pneumothorax was: 4/20 (20%) observation, 10/20 (50%) chest drain, 2/20 (10%) needle aspiration, 4/20 (20%) surgery. Twentythree/ 29 PSP (79.3%) underwent CT-scan after the first episode. Bullae were detected in 17/23 patients and 5/17 (29.4%) had seven episodes of recurrence. PSP patients treated by PSU were more likely to receive clinical observation. Those managed by TSU were mostly treated by chest drain. Observation seems an effective choice for clinically stable PSP, with low risk of recurrence at a mid-term follow-up. CT-scan seems not to detect those patients at higher risk of recurrence.

Laparoscopic resection of hepatocellular carcinoma. Considerations on lesions in the posterosuperior segments of the liver.

AIM: The aim of this study was to evaluate retrospectively our results for laparoscopic liver resection (LLR) of hepatocellular carcinoma (HCC) including lesions in the posterosuperior segments of the liver in terms of feasibility, outcome, recurrence and survival. MATERIAL OF STUDY: Between June 2005 and May 2009, we performed 22 LLR for HCC. The underlying cirrhosis was staged as Child A in 19 cases and Child B in 3. RESULTS: LLR included a non anatomic resection in 15 cases and an anatomic resection in 7. A conversion to laparotomy occurred in one (4.5%) patient for hemorrhage. Mortality and morbidity rates were 0% and 18.1% (4/20). Over a mean follow-up period of 29 months (range: 19-65 months), 11 (50%) patients presented recurrence, mainly at distance from the surgical site. DISCUSSION: A laparoscopic approach is more suitable when the lesion is located in the peripheral "laparoscopic" segments 2 to 6. Nevertheless, six resections were made in the posterosuperior segments. Although parenchymal-sparing resection is required by the presence of underlying liver disease, anatomic resection has always to be considered and pursued to reduce local recurrence. In our series the recurrence rate was similar to those reported for other laparoscopic studies and for open resection of HCC. CONCLUSIONS: LLR for HCC in selected patients is a safe procedure with good short-term results. It can also be proposed in tumor locations with a difficult surgical access maintaining a low morbidity rate and good oncologic adequacy. This approach could have an impact on the therapeutic strategy of HCC complicating cirrhosis as a treatment with curative intent or as a bridge to liver transplantation.

Laparoscopic lymph node biopsy for lymphoma with a novel use of indocyanine green fluorescence in a 66-year-old male patient.

INTRODUCTION: Indocyanine green (ICG) near-infrared fluorescence is primarily employed in detecting Intraoperative sentinel lymph node (SLN) mapping or to evaluate the extent of radical lymphadenectomy mainly in colo-rectal and gastric cancer. To date there are no reports indicating the use of this dye to detect pathologic lymphatic tissue when a lymph node biopsy for suspected lymphoproliferative disease is performed. PRESENTATION OF CASE: A 66-year-old male patient was admitted to the hospital for severe pain of left renal colic type. A computed tomography (CT) scan and a positron emission tomography (PET) showed a left hydroureteronephrosis due to ureter compression by paraortic solid tissue of lymphomatous aspect with a standardized uptake value (SUV) of 15. Multiple lymphadenopathies on paracaval, para-aortic and common iliac sites were present as well. DISCUSSION: A laparoscopic lymph node biopsy (LLB) was planned for diagnostic purposes. After induction of anesthesia a ICG solution was injected Intradermally at both inguinal regions. At laparoscopy a complete visualization of the pathologic lymphnodes was achieved, enabling incisional biopsies of the lymphomatous mass. Histopathological examination showed an extranodal localization of an aggressive B-cell non-Hodgkin lymphoma. CONCLUSION: ICG-fluorescence seems to offer a simple and safe method for pathologic lymph node detection. LLB in the suspicion of intra abdominal lymphoma can largely take advantage by this novel opportunity not yet tested to date. More studies with large case series are needed to confirm the efficacy of ICG-fluorescence for detecting pathologic lymph nodes.

Fluorescence-guided laparoscopic lymph node biopsy in a lymphoma patient: a possible new clinical application of indocyanine green.

To date, there are no reports indicating the use of indocyanine green (ICG) fluorescence to detect pathologic lymphatic tissue when a laparoscopic lymph node biopsy (LLB) for suspected new or recurrent lymphoma is performed. We present the case of a 72-year-old female patient admitted for suspicion of recurrent lymphoma. A preoperative imaging work-up showed solid tissue enveloping the terminal portion of the abdominal aorta with a standardized uptake value (SUV) of 10. Therefore, an LLB was planned. After induction of anesthesia, a ICG solution was injected intravenously and subcutaneously at both inguinal regions. At laparoscopy, a complete visualization of the pathologic lymph nodes was achieved, enabling an incisional biopsy of the lymphomatous mass. LLB with ICG-fluorescence offers a simple and safe method for pathologic lymph node detection in the suspicion of intra-abdominal lymphoma. More studies with large case series are needed to confirm the efficacy of this application.

Single-Port Cholecystectomy for Cholecystitis Versus Non-Cholecystitis.

Background and Objectives: To assess the safety and efficacy of single-port laparoscopic cholecystectomy (SPLC) for the treatment of symptomatic cholelithiasis in different gallbladder pathologic conditions. Methods: All patients who underwent SPLC in our department between October 1, 2017 and March 31, 2020 were registered consecutively in a prospective database. Patients' charts were retrospectively divided according to histological diagnosis: normal gallbladder (NG) (n = 13), chronic cholecystitis (CC) (n =47), and acute cholecystitis (AC) (n = 10). The parameters for assessing the procedure outcome included operative time, blood loss, use of additional trocars, conversion to laparotomy, intraoperative and postoperative complications, and length of hospital stay. Patient groups were statistically compared. Results: Seventy patients underwent SPLC. Duration of surgery increased from NG (55 ± 22.7 min) to CC (70 ± 33.5 min), and to AC patients (110.5 ± 50.5 min), which is statistically significant (P = .001). Postoperative complication rates were 7.6% in NG patients, 17% in CC, and 30% in AC (P = .442). Length of hospitalization was shorter for NG patients (1.0 ± 0.6 days) versus CC (2.0 ± 1.1 days) and AC patients (2.0 ± 4.7 days), with statistical significance (P = .020). Multivariate analysis found that pathology type and the occurrence of postoperative complications were independent predictors for prolonged operative times and prolonged hospital stay, respectively. Conclusion: SPLC is feasible for acute and chronic cholecystitis with good procedural outcomes. Since SPLC technique itself can be sometimes challenging with the existing technology, its application, especially in cases of acute cholecystitis, should be done with caution. Only prospective randomized studies on this approach for acute and chronic gallbladder diseases will assess the complete reliability of this technique.

Feasibility of Single-Port Laparoscopic Lymph Node Biopsy for Intra-Abdominal Lymphoma: A Case Series.

Background: Laparoscopic lymph node biopsy through a multi-port access (MPLB) is a well-established technique for intra-abdominal lymphoma diagnosis. The aim of the current study is to assess the feasibility and the diagnostic accuracy of the single-port laparoscopic lymph node biopsy (SPLB) in intra-abdominal lymphoma. Materials and Methods: Between October 2016 and February 2019, 15 patients underwent SPLB to rule out or to follow the progression of a lymphoma. The clinical outcome and the pathology reports were analyzed retrospectively. Results: SPLB was completed laparoscopically in all cases. The total number of biopsies performed for each procedure was sometimes multiple (median: 2; range: 1-3). Duration of surgery was 85 ± 32 minutes (range: 75-105 minutes). Length of hospitalization was 1.8 ± 0.7 days (range: 1-3 days). No major postoperative complications occurred. A cutaneous infection managed conservatively was observed in a patient. In 10 patients, SPLB was used to establish a diagnosis whereas in 5 patients it was performed to follow a progression of a lymphoproliferative disease. In 93.3% of the cases, SPLB achieved the correct diagnosis and subsequent therapeutic decisions. Conclusion: SPLB has shown good procedure and postoperative outcomes as well as a high diagnostic yield, comparable to literature data on traditional MPLB. Therefore, our results show that this approach is safe and effective and can be an equally valid option to MPLB to obtain a diagnosis or to follow the progression of a lymphoproliferative disease. Further studies are necessary to support these results before its widespread adoption.

Putative predictive parameters for the outcome of laparoscopic splenectomy: a multicenter analysis performed on the Italian Registry of Laparoscopic Surgery of the Spleen.

OBJECTIVE: To identify predictive risk factors for conversion to open splenectomy and postoperative complications in patients undergoing elective laparoscopic splenectomy. BACKGROUND: The laparoscopic approach represents the "gold standard" for splenectomy, but its use in the treatment of splenomegaly and malignant disease is controversial. Factors that influence immediate outcome are clinical, anatomic, and pathologic. METHODS: Univariate and multivariate analyses of data from the Italian Registry of Laparoscopic Surgery of the Spleen, a multicenter database supported by 25 referral centers. Analysis of data (1993-2007) was performed on a series of patients (n = 676) undergoing elective laparoscopic splenectomy. Demographic data, the operative indications, the surgical technique applied, and any intra- and/or postoperative complications with respect to the patients were assessed. Records were analyzed retrospectively using the Student t test, the chi test, and logistic regression. RESULTS: Conversion to open splenectomy was necessary in 39 cases (5.8%). Perioperative deaths occurred in 3 cases (0.4%). There were no complications in 560 patients (82.8%), with a mean hospital stay of 5 days (range, 2-54). Overall, morbidity occurred in 116 patients (17.2%). Multivariate analysis found that the body mass index (P = 0.01) and the presence of hematologic malignancy (P < 0.001) were independent predictors for intraoperative complications and surgical conversion. Spleen longitudinal diameter (P = 0.001) and surgical conversion (P = 0.001) were independent predictors for the occurrence of postoperative complications. CONCLUSIONS: This large multicenter study provides evidence for the significance of predictive risk factors for intra- and postoperative complications in laparoscopic splenic surgery. Besides splenic dimensions, other factors like the patient's habitus and the specific underlying hematologic pathology should be recognized by the surgeon to reduce complications and initiate adequate treatment.

Simultaneous laparoscopic anterior resection and left hepatic lobectomy for stage IV rectal cancer.

We report the case of a 68-year-old female patient affected by rectal cancer and a synchronous metastatic lesion measuring 8 cm in diameter in the left hepatic lobe. After a laparoscopic ultrasonography exploration of the liver to detect possible occult metastases, a simultaneous colorectal resection and a left hepatic lobectomy including a partial resection of segment IV were performed. Five ports were used for the entire procedure. The resected specimens were extracted through a Pfannenstiel incision. The procedure was completed laparoscopically. Total operative time was 455 minutes with negligible intraoperative blood loss. The postoperative hospital stay was 12 days. At 4-month follow-up, the patient recovered completely. A computed tomography scan performed at this time showed no signs of recurrent disease. This report confirms the feasibility of the laparoscopic approach to simultaneous hepatic and colorectal resections in stage IV rectal cancer. The known advantages of the miniinvasive approach could make such complex procedures more endurable.

Single-Port vs. Conventional Multi-Port Laparoscopic Lymph Node Biopsy.

BACKGROUND AND OBJECTIVES: The purpose of the investigation was to compare clinical results and diagnostic accuracy for conventional multiport laparoscopic lymph node biopsy (MPLB) and single-port laparoscopic lymph node biopsy (SPLB) operations at a single institution. METHODS: A set of 20 SPLB patients operated on from October 2016 to May 2019 were compared to an historical series of 35 MPLB patients. Primary endpoints were the time of surgery, estimated blood loss, surgical conversion, length of stay and morbidity. The secondary endpoint was the diagnostic accuracy of the technique. RESULTS: SPLB was completed laparoscopically in all cases. Two MPLB patients (5.7%) experienced a surgical conversion due to intraoperative difficulties. Duration of surgery was similar in SPLB and MPLB groups respectively (84 ± 31.7 min vs. 81.1 ± 22.2; P = .455). A shorter duration of hospital stay was shown for patients operated on by SPLB compared to the MPLB group (1.7 ± 0.9 days vs. 2.1 ± 1.2 days; P = .133). The postoperative course was uneventful in both groups. In 95% of the SPLB and 97.1% of the MPLB cases respectively, LLB achieved the necessary information for the diagnosis. CONCLUSION: SPLB has shown good procedural and postoperative outcomes as well as a high diagnostic yield, comparable to traditional MPLB. Therefore, our results show that this approach is safe and effective and can be an equally valid option to MPLB to obtain a diagnosis or to follow the progression of a lymphoproliferative disease. Further studies are necessary to support these results before its widespread adoption.

Laparoscopic staging and radiofrequency of hepatocellular carcinoma in liver ci rrhosis. A "bridge" treatment to liver transplantation.

BACKGROUND/AIMS: Surgical resection and liver transplantation are the only curative treatments for hepatocellular carcinoma, although limited to early stage disease. Our objective was to assess a novel operative combination of laparoscopic ultrasound with laparoscopic radiofrequency ablation of small hepatocellular carcinoma in potential candidates to liver transplantation when radiological evaluation is equivocal. We also evaluated the feasibility and efficacy of laparoscopic radiofrequency ablation. METHODOLOGY: Over a 2-year period, a laparoscopic ultrasound exploration and a laparoscopic radiofrequency ablation was performed in 15 patients (mean age 57+/-5.4 years; male/female 13/2) with hepatocellular carcinoma in liver cirrhosis. RESULTS: LRFA procedure was completed in all patients and a thermoablation of 36 hepatocellular carcinoma nodules was achieved. Laparoscopic ultrasound identified 12 new malignant lesions (46.1%) undetected by preoperative imaging. Six patients were up-staged as a result of the procedure and 3 were precluded from liver transplantation listing. A complete tumor necrosis was observed in 32 thermoablated nodules (88.8%) via spiral computed tomography 1 month after treatment. Seven patients underwent liver transplantation after a 5.8-month mean interval, and pathological staging of the explants agreed with laparoscopic staging for number/size of hepatocellular carcinoma nodules in all cases. Residual tumor was found in 2/12 (16.6%) thermoablated nodules, in two different liver specimens. CONCLUSIONS: Laparoscopic ultrasound accurately staged hepatocellular carcinoma in advanced cirrhosis with minimal morbidity and it can be used in potential candidates to liver transplantation. Laparoscopic radiofrequency ablation of hepatocellular carcinoma proved to be a safe and effective technique, representing a valid "bridge" treatment to liver transplantation or an effective palliative option.

Laparoscopic Single-Port Versus Traditional Multi-Port Laparoscopic Cholecystectomy.

BACKGROUND AND OBJECTIVES: Safety, efficacy, and costs are still debated issues in single-port laparoscopy. The aim of the study was to compare clinical outcomes and hospital costs for conventional 4-port laparoscopic cholecystectomy (4PLC) and single-port laparoscopic cholecystectomy (SPLC) performed at a single institution. METHODS: A series of 40 SPLC patients operated on from October 2016 to May 2017 were compared to a hystorical series of 40 4PLC patients. Primary endpoints were the operative time, blood loss, postoperative pain, analgesia requirement, length of stay, and morbidity. Secondary endpoints were the operative costs and total hospital costs. RESULTS: No patient required surgical conversion in both groups. Duration of surgery was significantly longer in the SPLC group. Length of hospitalization was shorter for patients operated on by SPLC (1.9 ± 0.9 vs 2.3 ± 1.2 days; P = .104). According to visual analogue scale evaluation, the pain profile was similar. Minor postoperative complications were present in 12.5% of the SPLC group and 2.5% in 4PLC group (P = .200). The total hospitalization costs associated with SPLC procedure were lower compared to standard 4PLC procedure. As regards the disposable operating room equipment costs, a statistically significant difference in favor of SPLC technique was found. CONCLUSION: SPLC has shown relevant procedure and postoperative outcomes when compared to traditional 4PLC. The technique has proved to be promising even in cases of acute cholecystitis considered to date a relative contraindication. Further studies are needed to confirm its safety and feasibility in this setting. In contrast with the current evidence of increased costs for the single-port technique, a reduction of material and hospitalization costs was experienced in our study.

Laparoscopic Splenectomy Versus Open Splenectomy In Massive and Giant Spleens: Should we Update the 2008 EAES Guidelines?

The objective of this study was to derive some useful parameters to define the feasibility of laparoscopic splenectomy (LS) in massive [spleen longitudinal diameter (SLD)>20 cm] and giant spleens (SLD>25 cm). Between December 1996 and May 2017, 175 patients underwent an elective splenectomy. A laparoscopic approach was used in 133 (76%) patients. Massive spleens were treated in 65 (37.1%) patients, of which 24 were treated laparoscopically. In this subset of massive spleens, the results of laparoscopic splenectomy in massive spleens (LSM) and open splenectomy in massive spleens (OSM) were compared. The clinical outcome of a subgroup of patients with giant spleens was also analyzed. The LSM group resulted in significant longer operative times (143±31 vs. 112±40 min; P=0.001), less blood loss (278±302 vs. 575±583 mL; P=0.007), and shorter hospital stay (6±3 vs. 9±4 d; P=0.004). No conversions were experienced in the LSM group, and the morbidity rate was similar in both the LSM and OSM groups (16.6% vs. 20%; P=0.75). When considering the subset of 9 LSM patients and 26 OSM patients with giant spleens, the same favorable tendency of the laparoscopic group as regards surgical conversion, blood loss, and hospital stay was maintained. The laparoscopic approach can be successfully proposed in the presence of massive splenomegaly also after a careful preoperative evaluation of the expected abdominal "working space." In experienced hands, LS is safe, feasible, and associated with better outcomes than open splenectomy for the treatment of massive and giant spleen, with a maximum SLD limit of 31 cm.

Single-Port Versus Conventional Laparoscopic Cholecystectomy: Better Cosmesis at the Price of an Increased Incisional Hernia Rate?

Background: The incidence of trocar site hernia (TSH) in single-port laparoscopic cholecystectomy (SPC) is still a debated issue. Aim of this retrospective study was to compare the incidence of postoperative hernia and cosmetic results among patients undergoing SPC and multiport laparoscopic cholecystectomy (MPC) performed at a single institution. Methods: A series of 60 SPC and 60 MPC patients operated on between July 2016 and May 2018 were compared. Primary endpoint was to assess the incidence of TSH at long term. All the patients were admitted as outpatients for physical examination and scar measurement. Secondary endpoints were the cosmetic results assessed by a cosmesis score (CS) and the body image questionnaire (BIQ). Results: After a median 18-month follow-up (range: 6-29 months), a hernia in umbilical trocar site was detected in 4 (7.1%) SPC patients and 1 (2%) MPC patient, the difference not being statistically significant (P = .216). BIQ was almost equivalent in SPC and MPC groups (5.15 versus 5.27; P = .518), respectively. Statistically significant differences in favor of SPC were found in CS (22.3 versus 19.72; P = .001) and in total length of scars (1.2 cm versus 4 cm; P < .001). Conclusions: SPC technique has proved to be safe and effective in experienced hands. Superior cosmesis of SPC over MPC is confirmed, but close attention to fascial closure is a vital component of SPC, and surgeons performing single-site surgery need to be aware of this increased potential for hernia formation.

Elective surgery for ulcerative colitis, ileo-rectal anastomosis or restorative proctocolectomy An Update.

BACKGROUND: Despite advances in the medical management of Ulcerative Colitis (UC), surgery is required in about a third of patients. AIMS AND METHODS: A review of the literature of the last 20 years was conducted in order to analyze the results of Ileo-Rectal Anastomosis (IRA) and of Ileal Pouch-Anal Anastomosis (IPAA) in the treatment of mild-to-moderate UC. Postoperative complications, functional results and the risk of cancer were analyzed in each of the two groups of patients. RESULTS: In IRA group postoperative morbidity is low, varying from 8 to 28%. The risk of urinary and sexual dysfunction are rare and fertility rates are higher, compared to IPAA. The cumulative probability of success (working IRA) is 84% at 5 years and 51-69% at 10 years. The postoperative morbidity of IPAA is higher; dehiscence and pelvic sepsis were observed respectively in 9.5% and in 5.5%. A sexual dysfunction is present in 3.4%. In 18.8% occurs pouchitis. The risk of failure of the pouch is 6.8% and increased to 8.5% after 5 years. The risk of cancer is higher after IRA than after IPAA, with a cumulative risk at 20 years of 6-14% and 4.2% respectively. DISCUSSION: The choice between IPAA or IRA is based upon patient's preference and clinical criteria (malignancy or sphincter injury). IPAA, intervention of choice, is burdened by a higher rate of complications, such as anastomotic leak with pelvic sepsis and subsequent functional pouch failure, pouchitis, infertility in young women, lesions of the pelvic nerves and portal vein thrombosis. There have been reports of cancer not only in the anal transitional zone, but also in the same pouch, either after mucosectomy that after stapled anastomosis. IRA is less invasive than IPAA and postoperative complications are lower. Does not require dissection of the pelvic and presents no risk of injury of the nerves of the urogenital sphere. The long-term results of the IRA are generally satisfactory and most of the patients stated that after the intervention improve both the health status and quality of life. CONCLUSION: Today IPAA is the gold standard. The IRA is indicated in selected patients where they meet the following requirements: normal sphincter tone, absence of severe perineal disease, rectum does not actively involved by the disease, absence of dysplasia or cancer.
