Anatomy of the Cavernous Sinus

The cavernous sinus is the crossroad of veins from various embryological origins, including the brain, eye, pituitary gland, dura, and cranium. Embryologically, the cavernous sinus is mainly formed from the pro-otic sinus; secondary anastomosis between the cavernous sinus and primitive tentorial sinus results in various anatomical variations in the drainage patterns of the superficial middle cerebral vein. Moreover, connections between the cavernous sinus and basal vein via the uncal vein, bridging vein, and petrosal vein from the superior petrosal sinus may exist. Retrograde drainage from the cavernous sinus into the cerebral veins is often observed in arteriovenous shunts involving the cavernous sinus, such as dural and carotid-cavernous fistulas, which are primarily treated using transvenous embolization. Understanding the anatomy of the cavernous sinus and its associated veins is essential for safe and reliable endovascular treatment.

Clinical outcome, quality of life, and mental health in long-gap esophageal atresia: comparison of gastric sleeve pull-up and delayed primary anastomosis

IntroductionPediatric surgeons have yet to reach a consensus whether a gastric sleeve pull-up or delayed primary anastomosis for the treatment of esophageal atresia (EA), especially of the long-gap type (LGEA) should be performed. Thus, the aim of this study was to evaluate clinical outcome, quality of life (QoL), and mental health of patients with EA and their parents.MethodsClinical outcomes of all children treated with EA from 2007 to 2021 were collected and parents of affected children were asked to participate in questionnaires regarding their Quality of Life (QoL) and their child’s Health-Related Quality of Life (HRQoL), as well as mental health.ResultsA total of 98 EA patients were included in the study. For analysis, the cohort was divided into two groups: (1) primary versus (2) secondary anastomosis, while the secondary anastomosis group was subdivided into (a) delayed primary anastomosis and (b) gastric sleeve pull-up and compared with each other. When comparing the secondary anastomosis group, significant differences were found between the delayed primary anastomosis and gastric sleeve pull-up group; the duration of anesthesia during anastomosis surgery (478.54 vs 328.82 min, p < 0.001), endoscopic dilatation rate (100% vs 69%, p = 0.03), cumulative time spent in intensive care (42.31 vs 94.75 days, p = 0.03) and the mortality rate (0% vs 31%, p = 0.03). HRQoL and mental health did not differ between any of the groups.ConclusionDelayed primary anastomosis or gastric sleeve pull-up appear to be similar in patients with long-gap esophageal atresia in many key aspects like leakage rate, strictures, re-fistula, tracheomalacia, recurrent infections, thrive or reflux. Moreover, HrQoL was comparable in patients with (a) gastric sleeve pull-up and (b) delayed primary anastomosis. Future studies should focus on the long-term results of either preservation or replacement of the esophagus in children.

Prostate Volume Influence on Postoperative Outcomes for Patients Undergoing RARP: A Monocentric Serial Analysis of 500 Cases.

A total of 500 consecutive patients who underwent RARP between April 2019 and August 2022 were included. Patients were dichotomized into two groups using a prostate volume cut-off of 50 mL (small and normal prostate (SNP) n = 314, 62.8%; large prostate n = 186, 37.2%). Demographic, baseline, and perioperative data were analyzed. The postoperative complications and readmission rates within 90 days after RARP were compared between groups. A univariate linear analysis was performed to investigate the association between prostate volume and other relevant outcomes. Patients with larger prostates had a higher IPSS score, and therefore, more relevant LUTS at the baseline. They had higher ASA scores (p = 0.015). They also had more catheter days (mean 6.6 days for SNP vs. 7.5 days for LP) (p = 0.041). All oncological outcomes were similar between the groups. Although statistical analysis showed no significant difference between the groups (p = 0.062), a trend for minor complications in patients with larger prostates, n = 37/186 (19.8%) for the LP group vs. n = 37/314 (11.7%) in the SNP group, was observed. Namely, acute urinary retention and secondary anastomosis insufficiency. Major complications with an SNP (4.4%) and LP (3.7%) (p = 0.708) and readmissions with an SNP (6.25%) and LP (4.2%) (p = 0.814) were infrequent and distributed equally between the groups. In univariate analysis, prostate volume could solely predict a longer console time (p = 0.005). A higher prostate volume appears to have minimal influence on the perioperative course after RARP. It can prolong catheter days and increase the incidence of minor complications such as acute urinary retention. However, it might predict minor changes in operating time. Yet, prostate volume has less influence on major complications, readmissions, or oncological results.

S36 Idiopathic Myointimal Hyperplasia of the Mesenteric Veins a Rare Mimic of Inflammatory Bowel Disease: A Systematic Review

Background: Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is an extremely rare non-thrombotic mesenteric veno-occlusive disease. IMHMV manifests with non-specific symptoms mimicking inflammatory bowel disease. Therefore, patients are initially misdiagnosed with and treated for acute severe ulcerative colitis. However, given its rarity, the optimal surgical intervention remain undefined. Hence, this study aimed to perform a systematic review to assess the various surgical procedures and associated outcomes for patients with IMHMV. Methods: We conducted a systematic search for articles reporting patients with IMHMV in MEDLINE, EMBASE, Cinahl, Scopus, Web of Science, and Cochrane Library. The search was conducted from 1946 to April 2022. We also retrospectively analyzed IMHMV cases managed at our institution until April 2022. The risk of bias of included studies was evaluated with a modified tool proposed by Murad et al A narrative synthesis of included studies was provided. Results: The search strategy retrieved 703 references, of which 54 studies were included. Fifty were case reports and 4 were case series. A total of 88 patients with IMHMV were included. Most patients (82%) were male, with a mean age of 56.6 years old (range: 13–83 years). The median follow-up was 24 months (range: 1 – 144 months) with surveillance performed primarily via endoscopic evaluation. Abdominal pain and diarrhea were the most frequent presenting symptoms. Most reports described involvement of the rectum and sigmoid colon (81%). Only 6 (8%) IMHMV cases were suspected preoperatively and underwent elective surgery. The majority (99%) of patients initially managed medically eventually required surgery. Only 1 patient sustained symptomatic resolution with medical management. The most common surgical procedures were Hartmann’s procedure (24%) and segmental colectomy (19%). Secondary anastomoses were reported in 10 cases and performed after endoscopic confirmation absence of disease between 2 – 10 months. A total of 3 (3%) patients underwent either total proctocolectomy or total abdominal colectomy/completion proctectomy with IPAA formation. Four (5%) complications were reported and these were noted to occur when the involved portion of the bowel was the ileum, ascending colon, or transverse colon. Nearly all (99%) patients achieved IMHMV resolution with primary surgical intervention. Only 1 (1%) patient required a completion total colectomy following IMHMV recurrence. The overall risk of bias was judged to be low in 4 studies, unclear in 19 studies, and high in 31 studies. Conclusion(s): IMHMV is a rare pathology typically diagnosed following surgical resection with only a few cases suspected preoperatively. Patients are oftentimes initially misdiagnosed with acute severe ulcerative colitis, because of the similarities in clinical manifestations. IMHMV is typically treated medically but surgical resection is nearly always needed due to failure of medical therapy. Surgical resection via Hartmann’s procedure or segmental colectomy have been shown to be safe and effective with a low risk of complications and recurrence. As a rare disease, more evidence is required to optimally inform surgical decision-making, but it appears that sparing the unaffected colon is reasonable. The creation of a national or global collaborative database would be useful to help optimize recommendations for patients with this rare disease.

Acute Mesenteric Ischemia: Preexisting Comorbidity Determines Short-Term Outcome and Quality of Life in Long-Term Survivors

Introduction: Acute mesenteric ischemia (AMI), either arterial or venous, is still a devastating disease with poor prognosis. It is unknown, whether AMI is associated with impaired quality of life (QoL) in long-term survivors. Material and Methods: This retrospective analysis includes 64 patients with occlusive arterial or venous mesenteric ischemia treated operatively between 2008 and 2016 at the University Medical Center Rostock. Short-term outcome with focus on comorbidities was measured by the Charlson comorbidity index (CCI) an instrument that operationally measures comorbidity based on 17 clinical parameters including age. Operative outcome in view of enterostomy placement and long-term outcome measured as QoL by the EQ-5D in the long-term survivors were evaluated. The EQ-5D is a standardized, self-reported five-dimension QoL questionnaire built to provide a simple and generic measure of health. Results: Thirty-day mortality was 60.9%, and in-hospital mortality was 70.3% (n = 45). No patient was discharged with a stoma. Patients with a primary anastomosis after the initial operation for AMI had a high leak rate of 27% (4/15 patients) compared to no dehiscence in the group of patients who had secondary anastomosis during second or third laparotomy. The long-term survivors had significantly lower CCI compared to the 45 nonsurvivors (median 4 [3, 4, 5, 6] vs. 6 [4, 5, 6, 7]). All long-term survivors had QoL assessment. QoL score was significantly impaired compared to an age- and sex-matched reference population. This impairment was not due to disease-specific sequelae such as presence of stool deviation or intestinal failure but due to preexisting risk factors as shown by an inverse relation between the CCI and QoL score. Conclusion: Herein, we show for the first time that long-term QoL in patients with AMI is impaired but this impairment is not due to disease-specific aspects but rather general risk factors underlying the presence of a higher level of comorbidities at the time of AMI.

Inframammary Fold Banking of the Non-Dominant Superficial Epigastric Vein (SIEV) in Unilateral Autologous Breast Reconstruction: A Simple and Helpful Backup Option for Revision Surgery

Free flaps from the lower abdomen represent the workhorses of modern autologous, microvascular breast reconstruction. Rare signs of venous congestion often become evident during the primary index operation, but a secondary shift of the initially dominant drainage of the DIEV system to the SIEV system with consequent malperfusion is a feared, rare event requiring urgent decision, and complex skill using vein grafts and additional anastomosis to restore a sufficient venous outflow. For secondary anastomosis of the SIEV, especially in stacked flaps, a vein graft to the DIEV or retrograde IMV may be necessary, but this requires an additional donor site, thus prolonging procedure time during the emergency operation and resulting in additional scars of the graft’s donor site. We report on a versatile, easy technique of scheduled inframammary fold banking of the dissected, flushed, and clipped non-dominant superficial epigastric vein (SIEV) in unilateral autologous breast reconstruction during the index operation. The banked graft may service as an easy and convenient accessible vein graft in the rare event of secondary shifting of the initial dominant drainage of the DIEV to the SIEV system with the need for urgent re-operation. We retrospectively evaluated the management and outcome of all suitable patients receiving autologous breast reconstruction with a unilateral abdominal DIEP or MS-Tram flap accompanied by banking of the SIEV in the breast pocket between 2017 and 2020 in the present study. In two out of 42 patients (4.8%) receiving autologous breast reconstruction with an abdominal DIEP or MS-TRAM flap with banking of the SIEV in the breast pocket, secondary malperfusion of the flap with progressive venous congestion occurred during the first 48 h perioperatively, between 2 and 37 (mean: 19.5) hours after skin closure. In both cases malperfusion was due to secondary SIEV system dominance, and the banked vein was used as an interpositional graft to the retrograde IMV (case 1) or the DIEV (case 2). Revision surgery lasted between 95 and 121 (mean: 108) minutes without the need for further vein graft harvesting, and further healing was uneventful. Based on the limited cases, inframammary fold banking of the non-dominant SIEV is a versatile, beneficial, and feasible concept with scarce additional dissection time and can be done in all unilateral breast reconstructions to have a reliable graft for emergency re-exploration. It is a useful approach in the context of spare part surgery and tissue banking to safeguard against the rare instance of venous congestion and need for an interpositional graft.

DOP17 In high-risk Crohn’s Disease patients, anastomosis configuration types have similar rates of endoscopic recurrence

Abstract Background There is conflicting data on the influence of surgical anastomosis configuration on endoscopic postoperative recurrence (POR) of Crohn’s disease (CD) following ileocolonic resection (ICR). Furthermore, whether this relationship differs by preoperative risk factors for POR has not been studied. We aimed to assess the role of ileocolonic anastomosis type on the rate and time to POR by preoperative POR risk. Methods Retrospective cohort study of adult CD patients who underwent ICR between 2009–2020 at a quaternary IBD referral center. Patients with a primary or secondary anastomosis and ≥1 postoperative colonoscopy were included. Endoscopic activity was assessed by modified Rutgeerts’ scoring. POR was defined as Rutgeerts’ ≥ i2b. Patients were categorized by anastomosis type: end-to-end (ETE), end-to-side (ETS), or side-to-side (STS). High-risk CD patients were defined by ≥1: age ≤ 30 years, active smoker, or ≥2 ICR for penetrating disease. Results 548 CD patients (52.6% female, age 35 y, 15.5% &amp;gt; 1 prior ICR, 19.7% on biologic prophylaxis, 74.8% high-risk for POR) were included in the study (Figure 1). The majority received a STS (52.0%, N=285), 27.2% ETS, and 20.8% ETE. Patients with an ETE were diagnosed with CD at a younger age (p=0.04), had more penetrating disease (p=0.01), hand-sewn anastomoses (p &amp;lt;0.001), and diverting loop ileostomies (p=0.02). There were no differences in prior ICR, smoking, biologic prophylaxis, or in median time from ICR to first post-operative colonoscopy (388.5 days, p=0.41) or POR detection (905 days, p=0.8) by anastomosis type. ETS patients had a shorter median follow-up time (3.9 y, p=0.02). The majority (55.7%) of all patients experienced POR (57% ETS; 55.4% STS; 54.4% ETE). Overall, there was no significant association between anastomosis type and POR rate (p=0.91) or time to POR (p=0.32). However, in high-risk CD patients, ETS was significantly associated with more rapid time to POR on log-rank (p=0.03) and multivariable Cox modeling (HR=1.51; p=0.04). Postoperative prophylactic biologic therapy initiated within 3 months of ICR significantly delayed POR in the overall cohort (HR=0.64; p=0.012) and the high-risk CD subgroup (HR=0.67; p=0.047). High-risk CD patients on prophylactic biologics had no difference in time to POR by anastomosis type (p=0.66). Conclusion In post-operative CD patients, there is no difference in rates of endoscopic recurrence by anastomosis configuration regardless of risk stratification. In high-risk patients, ETS was associated with more rapid endoscopic recurrence compared to other configurations, however prophylactic postoperative biologics may protect against this effect.

Congenital Colonic Stenosis: A Rare Gastrointestinal Malformation in Children.

Aims:Congenital colonic stenosis (CCS) is an extremely rare cause of low-intestinal obstruction in neonates/child. We report our experience with seven cases of CCS presenting with low-intestinal obstruction and diagnosed intraoperatively and also propose an algorithm for its appropriate treatment for the adequate outcome.Materials and Methods:It was a retrospective study of seven patients of CCS including two neonates (5-days and 15-days old), four infants (age range – 2–11 months), and one 24-month-old child admitted from 2014 to 2019. Information regarding the age of presentation, clinical presentation, physical findings, radiological and laboratory findings, details of surgery, and outcome was retrieved and analyzed.Results:The male-to-female ratio was 5:2. Patients were initially diagnosed as cases of Hirschsprung's disease in five and ileal atresia in two. A final diagnosis of CCS was made during surgery and histopathological examination of resected stenotic segment. The segment involved was ascending colon in three, transverse colon in two, and sigmoid colon and junction of descending and sigmoid colon each in one patient. Resection of stenotic colonic segment and primary end-to-end anastomosis was performed in two, divided stoma after resection of the stenotic segment and secondary anastomosis in three, and proximal loop terminal ileostomy followed by resection of the stenotic colonic segment and ileocolic anastomosis after 10–12 weeks in two.Conclusions:CCS is a rare but possible cause of large-bowel obstruction, in neonatal, infant, and children particularly when associated with a history of chronic constipation since birth. It should be kept in mind as a differential diagnosis while managing a case of neonatal and pediatric intestinal obstruction, particularly low-bowel obstruction along with a history of chronic constipation. Treatment should be individualized for each patient based on clinical status and associated anomalies to give the best results with less morbidity.

Thin superficial inferior epigastric artery perforator flap for reconstruction of the tongue.

The superficial inferior epigastric artery (SIEA) flap is widely used in the repair of large soft tissue defects of the extremities and in breast reconstruction. Because of the high fat content of the abdomen, it has been less used for glossectomy reconstruction. Here we present a series of seven patients who each underwent reconstruction with a thin SIEA flap after resection of the tongue. There were six men and one woman (mean age 48, range 24-66 years). All patients underwent preoperative computed tomographic (CT) angiography, and colour Doppler ultrasound (US) was used to select and map the most suitable SIEA. The flap was raised above the Scarpa's layer while adjusted the plane of dissection according to the specific needs for bulk in each case. All the flaps survived; one flap required a secondary anastomosis because of a venous anastomotic embolus. The size of flap used was 5.0cm×6.0cm - 7.0cm×9.0cm, and the flap was 0.8cm-1.4cm thick. The functional outcome was evaluated at 6 - 18 months follow up, when speech and swallowing were both good in all cases. The dissection above the pubic symphysis is an important refinement of the SIEA flap, and we conclude that the thin SIEA flap is a good choice for reconstruction after excision of cancer of the tongue.

Ideal timing of indwelling catheter removal after robot-assisted radical prostatectomy with a running barbed suture technique: a prospective analysis of 425 consecutive patients

ObjectiveTo compare prospectively early outcome and complications of catheter removal after robot-assisted radical prostatectomy (RARP) on the 4th or 7th day with a standardized running barbed suture technique.IntroductionThe time point of removing the indwelling catheter after RARP mainly depends on institute’s/surgeon’s preferences. Removal should be late enough to avoid urinary leakage and complications such as acute urinary retention (AUR) but early enough to avoid unnecessary catheter indwelling.Materials and methodsA consecutive single-institutional series of patients underwent RARP between July 2015 and August 2017 and were entered in a prospectively maintained data base. Between July 2015 and December 2016 a cystogram was performed on 7th postoperative day (group A), thereafter the cystogram was performed on 4th postoperative day (group B). Incidence of acute urinary retention (AUR), urinary tract infections (UTI) and adverse events between the two cohorts was compared.Results425 patients were analyzed (group A: n = 231; group B: n = 194). Both cohorts were comparable regarding demographic and oncological parameters. Watertight anastomosis was present in 84.8% in group A and in 82.5% in group B, respectively. AUR within 4 weeks after RARP occurred in 2.2% (n = 3) in A and 9.4% (n = 15) in B (p = 0.001). AUR within 72 h after catheter removal occurred in group A: 1% (n = 2) and in group B: 6.3% (n = 10) (p = 0.005). Symptomatic urinary tract infections occurred in 8.2% (n = 16) in group A and in 6.9% (n = 11) in group B. There were no differences in the rate of secondary anastomosis dehiscence. Age, BMI, prostate size, surgeon, or intraoperative bladder neck reconstruction were not correlated to the occurrence of AUR or UTI.ConclusionsThe removal of indwelling catheter on day 4 after a RARP with a running barbed suture shows similar anastomosis leakage rates as on the 7th postoperative day. However, AUR rates are higher for early removal. Patients scheduled for early removal should be carefully informed about the increased risk for AUR. Catheter indwelling time does not represent a risk factor for UTI.

Enterostomy complications in necrotizing enterocolitis (NEC) surgery, a retrospective chart review at Odense University Hospital

BackgroundThe aim was to investigate the incidence of postoperative complications to surgery for necrotizing enterocolitis (NEC) with primary focus on enterostomy related complications.MethodsA retrospective chart review of surgically treated NEC during the period from 2008 to 2014 was performed. Enterostomy with secondary anastomosis was our standard treatment. Postoperative complications were classified according to the Clavien-Dindo Classification (CDC).ResultsForty-two cases were included in the study. NEC was most frequently located in the small bowel and the length of resected intestine was median 15 cm (2–50). Thirty-nine (93%) patients received an ileostomy and the rest a colostomy. Twenty-two (52%) patients underwent a total of 35 reoperations, and 25 (71%) of these were stoma related with stenosis was the most frequent cause, other causes of reoperation were re-NEC, high-output ileostomy, Ileus and second look.ConclusionsThe rate of reoperation due to complications was high and most often caused by stoma related complications.

Intraoperative superficial inferior epigastric vein preservation for venous compromise prevention in breast reconstruction by deep inferior epigastric perforator flap

The aim of this study was to analyze our technique of intraoperative venous compromise management based on conservation of the superficial inferior epigastric vein (SIEV), and to undertake a retrospective review of our series of breast reconstructions by deep inferior epigastric perforator (DIEP) flap, followed by a review of other techniques reported in the literature. This retrospective study involves 198 breast reconstructions by DIEP flap performed between January 2010 and September 2017. Our surgical technique is related in detail, with a focus on venous compromise management. Operative time, re-intervention rate, hospital stay, and complications were all noted and analyzed, and a literature review dealt with other techniques of prevention and management of flap venous congestion. Among breast reconstructions by DIEP, 7.5% contained an episode of intraoperative venous compromise, as opposed to 6.5% postoperatively. The SIEV was used in 65% of cases of venous congestion. In our series, 15.1% of cases presented postoperative complications, and we observed a 2.5% flap failure rate (2%: venous thrombosis; 0.5%: arterial thrombosis). In all patients for whom venous drainage augmentation was performed, the flaps survived without partial loss. While average length of hospital stay in the group having undergone intraoperative secondary anastomosis was 7.5 days, in the group having undergone postoperative secondary anastomosis, it was 13.5 days. In cases of intraoperative venous congestion, while a second venous anastomosis may immediately increase duration of an initial intervention by 1hour and 45minutes, it is nonetheless likely to pronouncedly decrease need for surgical revision, cases of failure, rate of partial necrosis and overall hospital stay.

Infant progressive colonic stenosis caused by antibiotic-related Clostridium difficile colitis \u2013 a case report and literature review

BackgroundColonic stenosis is a rare cause of pediatric intestinal obstruction. The root cause underlying colonic stenosis is unclear and there is no fixed operation.Case presentationWe reported on a male infant with progressive colonic stenosis caused by antibiotic-related colitis. The infant was admitted to our hospital with pneumonia but developed progressive abdominal distension and diarrhea following antibiotic treatment with meropenem. Initial testing of stool culture showed a Clostridium difficile infection. Additional testing with barium enema imaging showed stenosis at the junction of the sigmoid and descending colon at first and another stenosis occurred at the right half of the transverse colon 3 weeks later. Staged surgical treatment was performed with primary resections of the two parts suffering stenosis, ileostomy, and secondary intestinal anastomosis. A pathological exam then confirmed the diagnosis of colonic stenosis and the patient had an uneventful recovery and has been recovering well as evidenced by the 1-year follow-up.ConclusionsBased on a review of the literature and our case report, we found that progressive colonic stenosis caused by colitis due to antibiotic-related Clostridium difficile infection is rare in infants. Infants with colitis and repeated abdominal distention, vomiting, and constipation should be treated with the utmost caution and screened. Despite this, clinical manifestations depended on the severity of the stenosis. Barium enema, colonoscopy, laprascopy or laparotomy and colonic biopsy are helpful for diagnosis and differential diagnosis. While both one-stage and multiple-stage operations are feasible, a staged operation should be used for multiple colonic stenoses.

Primary versus secondary anastomosis in intestinal atresia

PurposeNeonates with intestinal atresia (IA) undergo either primary anastomosis (PA) or ostomy creation with secondary anastomosis (SA). Our purpose was to compare outcomes for PA and SA and to assess factors influencing procedure selection. MethodsWe conducted a retrospective cohort study of neonates with IA between 2009 and 2015. Patient characteristics, operative details, and outcomes were collected. Surgeon-level preferences (defined as performing >50% PA or SA) were assessed using logistic regression. ResultsOf 92 IA patients, 70 (76.1%) underwent PA and 22 (23.9%) underwent SA. Neonates with PA had shorter hospitalizations (27 days vs. 95 days, p < 0.001), shorter total parenteral nutrition duration (19 days vs. 74.5 days, p < 0.001), and fewer readmissions (33.3% vs. 63.2%, p = 0.024). On multivariable regression analysis, higher Apgar scores (Odds Ratio (OR) 4.16, 95% Confidence Interval (CI) 1.20–14.29) and uncomplicated atresia (OR 3.97, 95% CI 1.37–11.48) were associated with PA. At the surgeon-level, utilization of PA varied from 43.5% to 100%. Surgeon preference is not influenced by the demographic, presentation, or surgical findings of this patient population. ConclusionsPA has better outcomes than SA. Though procedural selection is influenced by the clinical status of the neonate, however surgeon preference plays a significant role in this clinical decision.

Hartmann's Procedure or Primary Anastomosis for Generalized Peritonitis due to Perforated Diverticulitis: A Prospective Multicenter Randomized Trial (DIVERTI)

About 25% of patients with acute diverticulitis require emergency intervention. Currently, most patients with diverticular peritonitis undergo a Hartmann's procedure. Our objective was to assess whether primary anastomosis (PA) with a diverting stoma results in lower mortality rates than Hartmann's procedure (HP) in patients with diverticular peritonitis. We conducted a multicenter randomized controlled trial conducted between June 2008 and May 2012: the DIVERTI (Primary vs Secondary Anastomosis for Hinchey Stage III-IV Diverticulitis) trial. Follow-up duration was up to 18 months. A random sample of 102 eligible participants with purulent or fecal diverticular peritonitis from tertiary care referral centers and associated centers in France were equally randomized to either a PA arm or to an HP arm. Data were analyzed on an intention-to-treat basis. The primary end point was mortality rate at 18 months. Secondary outcomes were postoperative complications, operative time, length of hospital stay, rate of definitive stoma, and morbidity. All 102 patients enrolled were comparable for age (p= 0.4453), sex (p= 0.2347), Hinchey stage III vs IV (p= 0.2347), and Mannheim Peritonitis Index (p= 0.0606). Overall mortality did not differ significantly between HP (7.7%) and PA (4%) (p= 0.4233). Morbidity for both resection and stoma reversal operations were comparable (39% in the HP arm vs 44% in the PA arm; p= 0.4233). At 18 months, 96% of PA patients and 65% of HP patients had a stoma reversal (p= 0.0001). Although mortality was similar in both arms, the rate of stoma reversal was significantly higher in the PA arm. This trial provides additional evidence in favor of PA with diverting ileostomy over HP in patients with diverticular peritonitis. ClinicalTrials.gov Identifier: NCT00692393.

Hybrid Video-Assisted Thoracic Surgery With Segmental–Main Bronchial Sleeve Resection for Non–Small Cell Lung Cancer

The purpose of the current study is to present the clinical and surgical results in patients who underwent hybrid video-assisted thoracic surgery with segmental-main bronchial sleeve resection. Thirty-one patients, 27 men and 4 women, underwent segmental-main bronchial sleeve anastomoses for non-small cell lung cancer between May 2004 and May 2011. Twenty-six (83.9%) patients had squamous cell carcinoma, and 5 patients had adenocarcinoma. Six patients were at stage IIB, 24 patients at stage IIIA, and 1 patient at stage IIIB. Secondary sleeve anastomosis was performed in 18 patients, and Y-shaped multiple sleeve anastomosis was performed in 8 patients. Single segmental bronchiole anastomosis was performed in 5 cases. The average time for chest tube removal was 5.6 days. The average length of hospital stay was 11.8 days. No anastomosis fistula developed in any of the patients. The 1-, 2-, and 3-year survival rates were 83.9%, 71.0%, and 41.9%, respectively. Hybrid video-assisted thoracic surgery with segmental-main bronchial sleeve resection is a complex technique that requires training and experience, but it is an effective and safe operation for selected patients.

Secondary Anastomosis after Preoperative Botulinum Type A Toxin Injection in a Case with Long Gap Oesophageal Atresia

Secondary Anastomosis after Preoperative Botulinum Type A Toxin Injection in a Case with Long Gap Oesophageal Atresia

Primary vs. secondary anastomosis for superior mesenteric arterial occlusion.

Superior mesenteric arterial occlusion (SMAO) often requires massive bowel resection. We compared primary anastomosis with open abdominal surgery and secondary anastomosis after enterostomy creation for the management of SMAO. We retrospectively studied 27 patients who underwent massive bowel resection for SMAO; the patients were divided into 2 groups depending on the operative procedure: primary anastomosis with open abdominal surgery (P group) and secondary anastomosis after enterostomy creation (S group). The mean duration from the initial operation to final operation (closure of open abdomen or closure of enterostomy) was significantly shorter in the P group (4.6±0.9 days) than in the S group (26.8±9.4 days) (p<0.0001). No disease recurrence was observed in either group; however, 2 patients died of multiple organ failure in the S group. Primary anastomosis with open abdominal surgery is useful for patients with low acute physiology and chronic health evaluation (APACHE) II scores and secondary anastomosis should be performed in patients with high APACHE II scores. Further, it is important to perform timely enterostomy closure on the basis of precise examination of blood flow in the remnant bowel to avoid deterioration in the patients' quality of life.
