IPOM plus versus IPOM standard in incisional hernia repair: results of a prospective multicenter trial.

PURPOSE: Laparoscopic ventral hernia repair is a well-established technique with satisfying outcomes even at long term for the treatment of incisional and ventral hernia. However, the literature debate is still ongoing regarding the preferred surgical technique. Nowadays, two approaches are commonly adopted: the intraperitoneal onlay mesh repair (sIPOM) and the intraperitoneal onlay mesh reinforcement with defect closure before mesh placement (pIPOM). The aim of this prospective analysis is to compare the postoperative outcomes of patients treated for incisional hernia (IH) with sIPOM and pIPOM after 36 months follow-up in terms of recurrence, quality of life and wound events. METHODS: Patients receiving pIPOM and sIPOM for IH were actively followed up for 36 months. At the outpatient clinic, hernia recurrence (HR), mesh bulging (MB), quality of life with the Gastrointestinal Quality of Life Index (GIQLI) and wound events were assessed. RESULTS: Between January 2015 and January 2019, 98 patients underwent a pIPOM and 89 underwent an sIPOM. At 36 months, nine patients (4 in pIPOM and 5 in sIPOM) experienced an HR, while MB was recorded in four patients in pIPOM and nine in sIPOM. No statistically significant difference could be identified also in terms of final GIQLI score and wound events. CONCLUSIONS: LVHR with or without fascial closure, also in our study, provides satisfactory results in terms of safety and efficacy. The discordant results in the literature are probably related to independent variables such as the type of mesh, the type of suture and closure technique. Therefore, was the funeral of sIPOM done too early? STUDY DATASET IS AVAILABLE ON CLINICALTRIALS. GOV ID: NCT05712213.

Diagnostic value of arterial blood gas lactate concentration in the different forms of mesenteric ischemia.

PURPOSE: The role of serum lactate measurement in patients with intestinal ischemia still remains unclear. The aim of this study was to prospectively evaluate the diagnostic performance of arterial blood gas lactate concentrations in the patients with acute mesenteric ischemia and its different forms. METHODS: All the patients reporting abdominal pain associated with risk factors for mesenteric ischemia underwent arterial blood gas and contrast enhanced abdominal computer tomography (CT). RESULTS: At CT, 201 patients (70.7%) showed a nonischemic disease (group 1) and 83 patients (29.2%) showed findings of mesenteric ischemia. Out of these, 35 patients (42.1%) showed bowel ischemia secondary to non vascular causes (group 2) and 48 (57.8%) had a vascular intestinal ischemia (group 3). Out of these, 20 showed small bowel arterial occlusion (group 3a), 13 a small bowel nonocclusive ischemia (group 3b), 7 a venous small bowel occlusion (group 3c) and 8 showed isolated colonic ischemia (group 3d). The median lactate serum level was significantly higher in patients with vascular ischemia if compared with patients with nonischemic disease and secondary mesenteric ischemia (p < 0.0001; Kruskal-Wallis test). The areas under ROC curves for the lactate serum levels in the groups 2, 3, 3a, 3b, 3c and 3d were, respectively, 0.61, 0.85, 0.93, 0.93, 0.68 and 0.67. CONCLUSIONS: Arterial blood gas lactate levels seem to show good diagnostic accuracy in diagnosing small bowel arterial and nonocclusive ischemia and poor accuracy in diagnosing secondary mesenteric ischemia, small bowel venous ischemia and ischemic colitis.

Non operative management of blunt splenic trauma: a prospective evaluation of a standardized treatment protocol.

PURPOSE: The advantages of the conservative approach for major spleen injuries are still debated. This study was designed to evaluate the safety and effectiveness of NOM in the treatment of minor (grade I-II according with the American Association for the Surgery of Trauma; AAST) and severe (AAST grade III-V) blunt splenic trauma, following a standardized treatment protocol. METHODS: All the hemodynamically stable patients with computer tomography (CT) diagnosis of blunt splenic trauma underwent NOM, which included strict clinical and laboratory observation, 48-72 h contrast-enhanced ultrasonography (CEUS) follow-up and splenic angioembolization, performed both in patients with admission CT evidence of vascular injuries and in patients with falling hematocrit during observation. RESULTS: 87 patients [32 (36.7 %) women and 55 (63.2 %) men, median age 34 (range 14-68)] were included. Of these, 28 patients (32.1 %) had grade I, 22 patients (25.2 %) grade II, 20 patients (22.9 %) grade III, 11 patients (12.6 %) grade IV and 6 patients (6.8 %) grade V injuries. The overall success rate of NOM was 95.4 % (82/87). There was no significant difference in the success rate between the patients with different splenic injuries grade. Of 24 patients that had undergone angioembolization, 22 (91.6 %) showed high splenic injury grade. The success rate of embolization was 91.6 % (22/24). No major complications were observed. The minor complications (2 pleural effusions, 1 pancreatic fistula and 2 splenic abscesses) were successfully treated by EAUS or CT guided drainage. CONCLUSIONS: The non operative management of blunt splenic trauma, according to our protocol, represents a safe and effective treatment for both minor and severe injuries, achieving an overall success rate of 95 %. The angiographic study could be indicated both in patients with CT evidence of vascular injuries and in patients with high-grade splenic injuries, regardless of CT findings.

Stapled haemorrhoidopexy vs. Milligan-Morgan haemorrhoidectomy for grade III haemorrhoids: a randomized clinical trial.

The aim of this double blind randomized clinical trial was to compare the short-term and long-term outcomes of stapled haemorrhoidopexy (SH group) performed using a circular stapler with that of the Milligan-Morgan haemorrhoidectomy (MMH group). A total of 79 consecutive patients with grade III haemorrhoids were randomized into two groups treated with SH (n. 39) and MMH (n. 40). The outcomes of the procedures were evaluated postoperatively and over a follow-up period of minimum 2 years. Patients undergoing the SH procedure showed greater short term advantages than MMH group with reduced pain, shorter length of hospital stay, earlier return to work and high patient satisfaction. Long-term follow-up has indicated more favourable results in MMH group in terms of resumption of symptoms with absence of residual prolapse and risk of recurrence of prolapse. At two years follow-up recurrent prolapse was confirmed in six patients of SH group (13%) whereas in none of the MMH group. At six months follow-up there weren't significant difference in the mean satisfaction score for the two groups. At two years the mean satisfaction score was higher in the MMH group vs SH group. Seven patients in the SH group needed a reoperation whereas none in MMH group. From January 2009, in our Surgery Unit the patients are always informed about a higher recurrence rate of SH and we perform this technique only when the patient choices to accept this risk to take advantage of the short-term benefits of this procedure.

Traumatic abdominal wall hernia. Case report.

Despite the high incidence of abdominal traumas, traumatic abdominal wall hernias (TAWHs) remain rare probably because of elasticity of the abdominal wall. The TAWH is due to blunt abdominal trauma with disruption of the abdominal wall muscles and fascia with intact overlying skin. TAWH can be classified into high energy injures (generally motor vehicle accidents) and low energy injures (impact on a small blunt object). Common example of the latter type is a fall onto a bicycle handlebar. The mechanism of the trauma includes sudden increase of intra-abdominal pressure and extensive shear forces applied to the abdominal wall. The diagnosis of TAWH is difficult in the Emergency Room because during the primary diagnostic process most attention is directed toward the detection of internal injures and TAWH can be missed. In this article we report a case of TAWH caused by a work accident (an heavy steel tube fallen onto the abdominal wall of the patient from a height of five meters) with delayed diagnosis.

The effect of esophageal myotomy and myectomy on the lower esophageal sphincter pressure profile: intraoperative computerized manometry study.

SUMMARY: The surgical treatment of achalasia, based on Heller's myotomy is the procedure of choice to reduce the sphincterial high pressure zone, either by laparotomy or, most recently, by laparoscopy. What is the right length of the myotomy? Many authors have reported 10-15% postoperative residual dysphagia, due to the incomplete gastric myotomy and not to esophageal pouring. The aim of this study is to experimentally determine the modifications induced by Heller's myotomy and myectomy of the esophago-gastric junction on lower esophageal sphincter (LES) pressure profile, using a computerized manometric system. Myotomy of the esophageal portion of the LES (i.e. without dissection of the gastric fibers) has not modified the parameters considered, while the dissection of gastric fibers for at least 2-3 cm on the anterior gastric wall has created a significant modification of the LES pressure profile. Our observations seem to confirm and more clearly demonstrate the important role played by gastric fibers in sustaining the sphincteric HPZ. Moreover, analysis of our data, showed the need to always perform a complete myotomy. This was objectively shown during the intervention by means of intraoperative manometry, in order to significantly reduce the possibility of a dysphagic relapse, caused by inadequate treatment.

[Total gastrectomy for gastric cancer: can the type of lymphadenectomy condition the long-term results?]. / Gastrectomia totale per cancro gastrico: può il tipo di linfadenectomia condizionare i risultati a distanza?

INTRODUCTION: Gastric cancer is the second tumor for frequency in the world. Surgery is still the only curative treatment. Good results in terms of long distance survival, postoperative morbidity and mortality have been achieved in the last years. The extension of lymphadenectomy is an important and discussed matter and it is not clear if lymphadenectomy may contribute to improve the surgical results. The Japanese surgeons were the first ones, in the 60's, to introduce a D2-D3 extended lymphadenectomy, but the real benefits of this technique are still being discussed. Indeed lymphonodal metastasis seem to be one of the most important prognostic factors in the gastric cancer and the level and the number of metastatic nodes are useful to predict the patients' survival. The aim of this study is to value the D2 lymphadenectomy in the patients who were treated with total gastrectomy for gastric adenocarcinoma, comparing the results both with the D1 lymphadenectomy and the D3-D4, paying attention to the survival rates related with the lymphonodal dissection. PATIENTS AND METHOD: From 1998 to 2004, we studied 87 patients with gastric cancer. Out of 78 patients treated surgically, 9 were judged unresectable. Out of 69 patients treated surgically, one died before surgery and so he was put away by this study. All the patients were treated with total gastrectomy and a GI tract reconstruction by Roux's Y termino-lateral esophageal-jejunal anastomosis. In 20 patients we also made a splenectomy. We followed the Japanese Research Society for Gastric Cancer guidelines, according to which nodes are gathered into 16 levels and divided in 4 groups (N1-N4) depending on the cancer localization. The extension of the lymphadenectomy has been classified according to the level of the removed nods. The patients were divided into 3 groups. First group: patients undergone a total gastrectomy with D1 lymphadenectomy. Second group: patients undergone D2 lymphadenectomy. Third group: patients undergone D3 and D4 lymphadenectomy. The data we obtained let us value the survival rate. RESULTS: Out of the 78 patients treated, 69 were resected with a 88.5% resection rate (69/78). Perioperatory mortality was 1.4% (1/69). Global survival was 53.8% (44/68). The 5 years survival for the Ia stage was 82.6%, 89.3% for the Ib stage, 67.8% for the II stage, 56.6% for the IIIa, 16.8% for the IIIb and 0% for the IV stage. In addition the 5 years survival in the patients without lymphnodal metastasis was 79%, much higher than the 30.6% obtained in the patients with lymphonodal metastasis (p <0.0001). In the patients who underwent D1 lymphadenectomy, survival was 73.4%, while we obtained a result of 70.4% and 13.8% respectively in the D2 and D3-D4 (p <0.05). In the advanced stages (IIIa, IIIb, IV), the survival rate in the patients with lymphadenectomy D2 vs D1 vs D3-D4 was 38.9% vs 0% vs 36.3% (p <0.0001). The survival rate based on the extension of the lymphadenectomy in the patients with lymphonodal metastasis resulted to be much higher in those patients who underwent a D2 lymphadenectomy (43.5% in 5 years) compared both to D1 (0% in 6 months) and (29.5% in 5 years) D3-D4 lymphadenectomy. CONCLUSIONS: The relation between long distance survival and extension of the lymphadenectomy in the patients with gastric adenocarcinoma is still being discussed. Different studies show the importance of a careful lymphadenectomy as the main mean for a better long distance survival in the patients with gastric cancer. Other studies showed a link between gastric cancer prognosis and number of positive nodes. If more than 7-8 nodes are affected with metastasis, prognosis is usually poor. Therefore the presence of nod metastasis has a negative influence in the prognosis of this tumor; for this reason D2 lymphadenectomy is the technique to be used for the treatment of the gastric adenocarcinoma, both for a good staging and a better long distance survival, but particularly in the advanced cancers which are, at the moment, the highest number of cases that reach the surgeon's attention.

Gastric cancer in the elderly patient.

The incidence of gastric cancer is increasing in elderly patients, unlike what it's being observed in the younger patients. The aim of this study is to evaluate the impact of the age on the resecability, resection type (R0-R1-2), morbidity, mortality and survival rate. The higher mortality observed in the elderly patients, the discussed role of an extended lymphadenectomy and the poor survival rate, would lead to a surgical approach which mostly tends to the palliation of the symptoms than the obtainment of a curative resection. But, on the other hand, the impossibility of making chemotherapy in most of the over 75 year old patients, lead us to a R0 surgery treatment.
