Update of Guidelines for laparoscopic treatment of ventral and incisional abdominal wall hernias (International Endohernia Society (IEHS)) : Part B
In 2014 the International Endohernia Society (IEHS) published the first international "Guidelines for laparoscopic treatment of ventral and incisional abdominal wall hernias". Guidelines reflect the currently best available evidence in diagnostics and therapy and give recommendations to help surgeons to standardize their techniques and to improve their results. However, science is a dynamic field which is continuously developing. Therefore, guidelines require regular updates to keep pace with the evolving literature. Methods For the development of the original guidelines all relevant literature published up to year 2012 was analyzed using the ranking of the Oxford Centre for Evidence-Based-Medicine. For the present update all of the previous authors were asked to evaluate the literature published during the recent years from 2012 to 2017 and revise their statements and recommendations given in the initial guidelines accordingly. In two Consensus Conferences (October 2017 Beijing, March 2018 Cologne) the updates were presented, discussed, and confirmed. To avoid redundancy, only new statements or recommendations are included in this paper. Therefore, for full understanding both of the guidelines, the original and the current, must be read. In addition, the new developments in repair of abdominal wall hernias like surgical techniques within the abdominal wall, release operations (transversus muscle release, component separation), Botox application, and robot-assisted repair methods were included. Results Due to an increase of the number of patients and further development of surgical techniques, repair of primary and secondary abdominal wall hernias attracts increasing interests of many surgeons. Whereas up to three decades ago hernia-related publications did not exceed 20 per year, currently this number is about 10-fold higher. Recent years are characterized by the advent of new techniques-minimal invasive techniques using robotics and laparoscopy, totally extraperitoneal repairs, novel myofascial release techniques for optimal closure of large defects, and Botox for relaxing the abdominal wall. Furthermore, a concomitant rectus diastasis was recognized as a significant risk factor for recurrence. Despite still insufficient evidence with respect to these new techniques it seemed to us necessary to include them in the update to stimulate surgeons to do research in these fields. Conclusion Guidelines are recommendations based on best available evidence intended to help the surgeon to improve the quality of his daily work. However, science is a continuously evolving process, and as such guidelines should be updated about every 3 years. For a comprehensive reference, however, it is suggested to read both the initially guidelines published in 2014 together with the update. Moreover, the presented update includes also techniques which were not known 3 years before

Internal sphincterotomy reduces postoperative pain after Milligan Morgan haemorrhoidectomy
<p>Abstract</p> <p>Background</p> <p>Over the last few years, there has been increasing attention on surgical procedures to treat haemorrhoids. The Milligan-Morgan haemorrhoidectomy is still one of the most popular surgical treatments of haemorrhoids. The aim of the present work is to assess postoperative pain, together with other early and late complications, after Milligan-Morgan haemorrhoidectomy as we could observe in our experience before and after performing an internal sphincterotomy.</p> <p>Methods</p> <p>from January 1980 to May 2007, we operated 850 patients, but only 699 patients (median age 53) were included in the present study because they satisfied our inclusion criteria. The patients were divided into two groups: all the patients operated on before 1995 (group A); all the patients operated on after 1995 (group B). Since 1995 an internal sphincterotomy of about 1 cm has been performed at the end of the procedure. The data concerning the complications of these two groups were compared. All the patients received a check-up at one and six months after operation and a telephone questionnaire three years after operation to evalue medium and long term results.</p> <p>Results</p> <p>after one month 507 patients (72.5%) did not have any postoperative complication. Only 192 patients (27.46%) out of 699 presented postoperative complication and the most frequent one (23.03%) was pain. The number of patients who suffered from postoperative pain decreased significantly when performing internal sphincterotomy, going from 28.8% down to 10.45% (χ<sup>2</sup>: 10,880; p = 0,0001); 95% Confidence Interval (CI) 24.7 to 28.9 (group A) and 10.17 to 10.72 (group B). In 51 cases (7.29%) urinary retention was registered. Six cases of bleeding (0.85%) were registered. Medium and long term follow up did not show any difference among the two groups.</p> <p>Conclusion</p> <p>internal sphincterotomy: reduces significantly pain only in the first postoperative period, but not in the medium-long term follow up; does not increase the incidence of continence impairment when performed; does not influence the incidence of the other postoperative complications especially as regard medium and long term results.</p
MRCP compared to diagnostic ERCP for diagnosis when biliary obstruction is suspected: a systematic review
BACKGROUND: Magnetic resonance cholangiopancreatography (MRCP) is an alternative to diagnostic endoscopic retrograde cholangiopancreatography (ERCP) for investigating biliary obstruction. The use of MRCP, a non-invasive procedure, may prevent the use of unnecessary invasive procedures. The aim of the study was to compare the findings of MRCP with those of ERCP by the computation of accuracy statistics. METHODS: Thirteen electronic bibliographic databases, covering biomedical, science, health economics and grey literature were searched. A systematic review of studies comparing MRCP to diagnostic ERCP in patients with suspected biliary obstruction was conducted. Sensitivity, specificity, likelihood ratios, acceptability and adverse events were reported. RESULTS: 25 studies were identified reporting several conditions including choledocholithiasis (18 studies), malignancy (four studies), obstruction (three studies), stricture (two studies) and dilatation (five studies). Three of the 18 studies reporting choledocholithiasis were excluded from the analysis due to lack of data, or differences in study design. The sensitivity for the 15 studies of choledocholithiasis ranged from 0.50 to 1.00 while specificity ranged from 0.83 to 1.00. The positive likelihood ratio ranged: from 5.44–47.72 and the negative likelihood ratio for the 15 studies ranged from 0.00–0.51. Significant heterogeneity was found across the 15 studies so the sensitivities and specificities were summarised by a Receiver Operating Characteristic (ROC) curve. For malignancy, sensitivity ranged from 0.81 to 0.94 and specificity from 0.92 to 1.00. Positive likelihood ratios ranged from 10.12 to 43 and negative likelihood ratios ranged from 0.15 to 0.21, although these estimates were less reliable. CONCLUSION: MRCP is a comparable diagnostic investigation in comparison to ERCP for diagnosing biliary obstruction
Recent Innovations & Daily Problems. A new prosthesis in inguinal hernia repair:preliminary results of a pilot study.
Introduction: Elective surgery for inguinal hernia is affected by very
low mortality « 1 per 10000 operation); in contrast, when surgery
is carried out for complicated inguinal hernia, risks of postoperative
complication are higher. TAPP is a world-wide accepted surgical practice
in the treatment of elective bilateral or recurrent inguinal hernia,
above all in young patients. Few exploratory studies were published on
laparoscopic approach in the treatment of urgent complicated inguinal
hernia. Aim of this study was to analyze feasibility (operative time,
conversion rate), safety (postoperative morbidity, length of hospital
stay) and quality of life (acute and chronic pain, return to work) of
trans-abdominal pre-peritoneal laparoscopic hernia repair in acute
incarcerated inguinal hernia. Rationale of laparoscopic trans-abdominal
approach is the easier hernia reduction under vision and a better
exploration of the abdominal cavity.
Methods: from September 2012 to September 2013, 15 consecutive
patients admitted in emergency at the Division of General Surgery of
University "Sapienza", Polo Pontino, for acute incarcerated inguinal
hernia were submitted to TAPP using 3 trocars (1 of 10 mm and 2 of
5mm) and polyester prosthesis fixed by fibrin glue. Exclusion criteria
for laparoscopic approach were age III, previous
abdominal surgery, signs of strangulated hernia. All of them were
evaluated for operative time, conversion rate, postoperative morbidity,
organ resection or other surgery required. All patients were scored for
pain by Visual Analogic Scale (VAS) during postoperative in hospital
stay at 7 days, 1,6 and 12 months after surgery.
Results: median follow-up was 16 months and 12 as minimum. In all
cases reduction of hernia was always possible and none conversion
to open surgery was recorded, median operative time was 89 minutes
(55-137 as range), omental resection was carried out in one patient
(6,6%), no other organ resections needed, whereas contralateral hernia
was diagnosed and repaired at the same time in 4 patients (26,6%). No
major complications were observed, median blood loss was 100 ml,
minor morbidity was contained to 18% represented by fever and
wound infection of surgical umbilical scar. Median in hospital stay
was 1,5 days with 1-5 days as range. Postoperative median acute pain,
measured by visual analogic scale (VAS), was 2 (range:0-4), none
patient referred any pain during follow-up. Median time of return to
work was 6,5 days, ranged between 3 to 15 days. Patients' compliance
to treatment and to follow-up was complete as well their satisfaction. Conclusions: In centres skilled for laparoscopy in emergency, TAPP
could be considered a feasible and safe technique. In well-selected
patients (especially if emolled in controlled clinical trial) TAPP could
represent an alternative surgical approach for complicated incarcerated inguinal hernia to conventional open surgery even in urgency. The
main advantages of laparoscopic approach are the ability to perform
surgical hernia reduction under vision, a better exploration and evaluation
of abdominal cavity and diagnosis and treatment of eventual
contralateral defect of wall, otherwise often missed. Finally, the good
control of acute and chronic pain, faster return to normal activity and
work, better aesthetic results contributed to total satisfaction and compliance
of the patients
Comparison Between Laparoscopic Sleeve Gastrectomy and Laparoscopic Adjustable Gastric Banding for Morbid Obesity: a Meta-analysis
CLOSURE OF GASTROTOMY IN NATURAL ORIFICE TRANSLUMINAL ENDOSCOPIC SURGERY: A FEASIBILITY STUDY USING AN EX VIVO MODEL COMPARING ENDOLOOP WITH ENDOCLIP
Background: Closure of access site is one of the key issues that will determine the development of natural orifice transluminal endoscopic surgery. Our study was designed to compare the effectiveness of gastrotomy closure using endoloop and endoclip with hand-sewn closure as a control. Methods: Gastrotomy was carried out on 24 ex vivo porcine stomachs and the gastrotomies were randomized to be closed with either hand-sewn, endoloop or endoclip techniques. A 2 cm gastrotomy was created with a needle knife and sphincterotome and the defects closed thereafter. We measured the time to closure of gastrotomy and the pressure at which the closure leaked. Results: Three endoloops were required for all the closures in the endoloop group. In the endoclip group, the mean (range) number of endoclips used was 10 (8-13). There was no difference in the median closure times between endoloop 28 (16-58) min and endoclip 30 (21-40) min; however, time for hand-sewn closure was much shorter (3-5 min). All stomachs were successfully distended with air without leak at the end of the procedure and none experienced fluid leak. The endoclip closure endured a significantly higher median (range) pressure of 72.5 mmHg (15-80 mmHg) before leaking compared to that of an endoloop 25 mmHg (15-37 mmHg) (P < 0.001). The hand-sewn gastrotomy leaked at pressure of 95 mmHg (75-130 mmHg). The majority of air leaks were from the wound site. In the endoclip group, two leaks were noted at the clip bite site. Conclusion: In a bench-top model, endoclips seem to be better for gastrotomy closure because of their potential to endure relatively higher pressure without any prolongation of application time. Animal survival studies are needed to explore technical and wound-closure-related problems arising as a result of use of endoclips and endoloops for gastrotomy closure
Plasma opioid levels during extracorporeal gallstone lithotripsy.
Plasma levels of beta-endorphin (beta-EP), met-enkephalin (met-ENK), ACTH, cortisol, and prolactin were measured in 20 patients who underwent extracorporeal gallstone lithotripsy (ESWL) before the treatment, at 500 shock waves (SW) (15-20 min), at 1000 SW (40-50 min), and 10 min after the end of ESWL. According to the Visual Analog Scale, nine patients had no pain, seven patients had pain from level 1 to 5, and four patients had pain from 5 to 10. No complications were observed. Plasma beta-EP values increased during the treatment, both in patients without pain and in those with pain. Only in the former group was the increase significant (baseline values (pmol/L): no pain = 4.04 +/- 1.3; pain 1-5 = 3.6 +/- 1.06; pain 5-10 = 2.9 +/- 0.5. Peak values: no pain = 6.6 +/- 1.2 (p < 0.005); pain 1-5 = 4.6 +/- 2.5; pain 5-10 = 4.5 +/- 2.2). Moreover, a negative correlation between beta-EP levels and individual pain scores during ESWL has been observed (CC = -0.64, p < 0.003). Plasma met-ENK levels reached the peak at 1000 SW and declined 10 min after the end of the treatment, although they were always higher than basal values (baseline values (pg/ml): no pain = 45 +/- 12; pain 1-5 = 38 +/- 10; pain 5-10 = 48 +/- 8. Peak values: no pain = 112 +/- 42 (p < 0.005), pain 1-5 = 114 +/- 48 (p < 0.005), pain 5-10 = 85 +/- 10 (p < 0.005). This behavior has been the same, regardless of the presence or absence of pain. We conclude that during ESWL, a rise of beta-EP and met-ENK occurs, and the increase of the former can be responsible for induction of analgesia because of its inverse correlation with pain intensity
