Giant Paraesophageal Hiatal Hernia repair
Giant Paraesophageal Hiatal Hernia repair: the need for the Collis operation? Ross M. Bremner MD, PhD William Pilcher Chair : Department of Thoracic Surgery and Transplantation Director, Norton Thoracic Institute St Joseph’s Hospital and Medical Center Professor of Surgery Creighton University Disclosures Institutional Support for research and education from Ethicon Surgical Consultant for Endostim Neither relevant to this talk St Joseph’s Hospital • Largest Hospital • Oldest Hospital University of Pittsburg Fear the Underdog! The large hiatal hernia – the need for a lengthening procedure Lets take a “grand view” Pathophysiology of Hiatal Hernia • • • • • Natural weakening “hiatus” in the diaphragm Congenital predisposition – Collagen I/III Activity Obesity Normal forces at the hiatus – over time • • • • • Respiration Swallowing Coughing/Sneezing Heaving/Vomiting Activity - lifting Edmundowicz SA, Clouse RE: Am J Physiol 260:G512–G516, 1991 Hiatal Hernia 60% of people over age 60 yrs Normal Breathing : Negative Inspiratory Pressure • Breathing • 20 000x day • 438 000 000 x in 60 yrs • Each breath – 10 mmHg Normal Shortening with Swallowing • Swallow – 2000x day – Shortens up to 3-5 cm at hiatus Coughing and Sneezing Addington WR: Cough, 2008, April 30:4;2 Normal Physiologic GE Junction forces Jumping >170 mmHg Further, increased change in intraabdominal pressure with increased BMI! Cobbs WS: J Surg Res, 2005 Dec;129(2) 231. Obesity Increased intraabdominal pressure Associated with increased risk of recurrence With Time…..little surprise • Diaphragm widens • Phreno-esophageal ligament stretches • Proximal Stomach herniates Control any Heartburn • With Time…. • GIANT PARAESOPHAGEAL HERNIA Point # 1 Many forces exist at the hiatus that tend to pull and push the stomach into the chest This is our battle as surgeons!! The large hiatal hernia – the need for surgery Why do we operate Symptoms associated with the hernia itself GERD And to prevent: Torsion Hemorrhage Large Paraesophageal HH What do we know? • Becoming more common! • Different beast • Operation more complex • More mobilization, larger defect, poorer diaphragmatic tissue • Recurrence COMMON • UP TO 50%!!!..Maybe higher The large hiatal hernia • Why so many? – Use of PPI’s –Pts (and GI’s) treat the disease medically for decades – Aging Population – Epidemic of obesity – GERD and hiatal hernia The large hiatal hernia • Recurrence! • How to mitigate against recurrence •Suture techniques •Patches •Glues •Relaxing incisions •Esophageal lengthening Recurrence – Why? Crural Tension Poor Diaphragm Tissue No reinforcement of crural repair Loose crural repair Perioperative heaving/straining Repetitive dry heaving Obesity Trauma Esophageal shortening J Leigh Collis (1911-2003) • Oesophageal surgeon with superior outcomes • 1957 devised a procedure to overcome peptic stricture and the “short esophagus” • No Nissen/Belsey Collis JL, Thorax 1957;12:181-188 Transthoracic Thoracotomy Pearson, FG, Cooper JD, Patterson GA (1987) Ann Surg 206 Laparoscopic Collis- Thoracoscopic Approach Collis- Laparoscopic Linear Stapler Approach (Wedge Gastroplasty) Completed Collis-Nissen Problem 1 Acid secreting epithelium above “wrap” Esophagitis 11-80% Zehetner J: Ann Surg 2014 Martin, C Aust.N.Z. J. Surg 1992, 62, 126-129 Problem 2 Amotile neoesophagus -Dysphagia Dilation of neoesophagus with time Problem 3 Staple line Leaks “Ischemic Collis” Point #2 Collis is a reasonable option IF the esophagus really is SHORT Not Physiologic, and may have immediate and long term side effects The Short Esophagus How do we predict? EGD? Manometry? What is too short? 20 cm Pathophysiology of the Short Esophagus • Repeated chemical trauma and mucosal sloughing • PMN Infiltration • Fibroblast Induction Today: Scleroderma • Collagen Deposition (submucosa and muscularis) • Shortening (axial and circumferential) Oberg, Ann Surg, 1997 RARE for stricture in giant HH Can we predict a SHORT esophagus – how often does it occur? Esophageal Length 102 pts with redo or PEH (1/3 Vagotomy – inadvertent or intentionally) No Collis needed in any case! Satisfied>90% “The Short Esophagus is an uncommon problem” Oelschlager,B: J Gastrointest Surg (2008) 12:1155-1162 Typical Example Large Hiatal Defect Dissect out the sac Identify Vagus Identify Posterior Vagus Close Crus…just right The Crus! The Achilles heal Nissen or Toupet Intraop Endoscopy St Joes Data – ongoing study Prospective onlay patch 2009-present >680 LARS with patch 435 PEH <2% Collis Reoperation <3% But we still see Recurrences!! Recurrence due to: • Intraabdominal forces Greater in Hi BMI • Inherent weakness at the hiatus • Disruption of the phreno-esophageal ligament?? Pig experiment 1992 • CUSA with Nissen • 5 Pigs • Nissen fundoplication (with circumferential dissection of the esophagus) then mucosal ablation – no HH – no crural repair • In 3 weeks - 3 animals acutely herniated their stomach into the chest Why? What can we learn from new procedures? The Phreno-esophageal membrane The Phreno-Esophageal Ligament Have we forgotten? Hayward, J: Thorax March 1961: 16(1); 41-45. Phreno-esophageal membrane Hayward, J: Thorax March 1961: 16(1); 41-45. Short Esophagus John Hayward “I have never been unable to reduce the hernia. An oesophagus too short to allow reduction of a hiatal hernia must be an unusual finding. Doubtless I shall encounter one sooner or later.” Hayward, J: Thorax March 1961: 16(1); 41-45. Why the failures Recurrent hiatal hernias: We repair the hernia • BUT • We have done nothing to change the normal pressure gradients at the hiatus • And no PEL With Time…..little surprise • Herniated stomach – Often only “portion” of stomach – Same whether Collis used or not. Point #3 Same forces that caused hernia in first place…..STILL EXIST post-op And the PEL is disrupted No wonder we get recurrences! How important is a recurrence? Fact is: most are asymptomatic Long Term Recurrence Multicenter Randomized Trial PEH 6 months : 9% (vs 24%) 58 months: 50%! But, almoat all were better Only 3% reoperation! Oelschlager B, Pelligrini C, Hunter J, Soper N, Swanstrom L: Am College Surg 2010 Oelschlager B: J Gastrointest Surg (2012) 16:453 Analysis of the impact of radiographic recurrence on gastroesophageal reflux disease-related and overall patient health status at current clinical follow-up Radiographic Recurrence All Patients Yes No ________________________________________________ Satisfied with surgery and current symptoms n = 493 n = 41 n = 314 Yes No 440 (80%) 53 (11%) 37 (90%) 4(10%) 284 (90%) 30 (10%) P .79+ Point #4 “Recurrence” Radiographic recurrence common And will likely continue…. MOST ASYMPTOMATIC But… risk of Torsion and Hemorrhage Gone! But, you say…. The Collis will lengthen the esophagus and prevent recurrence?? Does the Collis Mitigate against Recurrence? 68 pts with Collis Mean follow up 30 months! 17% recurrence hiatal hernia (80% esophagitis) “Calls into question the LIBERAL application of this technique” Lin, E, Smith C D: J Gastrointest Surg 2004;8:31-39 Collis(454 pts) vs No Collis(341) Radiographic recurrence similar! 17% vs 20% (>3 months) Reoperation Similar 3-5% Nason K, Luketich J, Ann Thorac Surg 2011;92:1854 Point # 5 The Collis Does NOT Prevent Recurrence How Good is the Collis? Short Term. Is this a safe operation we should be advocating? Collis(454 pts) vs No Collis(341) Leaks No Collis: 2 pts Collis: 12 pts Reoperation < 30 days Collis : 6 No-Collis : 3 p<0.05 Nason K, Luketich J, Ann Thorac Surg 2011;92:1854 Outcomes “Long-term symptomatic outcomes after Collis gastroplasty” 52 pts Long-term = >9 months! Resolution: HB Chest Pain Dysphagia 52% 22% 29% Conclude “good long term symptom control” Garg, N: Diseases of the Esophagus (2009) 22, 532 Collis vs No-collis Long term outcomes: “SIMILAR” But Very little >5 or 10 year data on Collis Nissen and its functional outcomes Why use a Collis? • Esophageal shortening result of panmural fibrosis, uncommon in todays world • Collis is unphysiologic – problems! • High recurrence rate of paraesophageal hernia not due to shortening • Most are asymptomatic • Most recurrences do not need reoperation! Pt’s are satisfied! • “Lengthening” the esophagus does not mitigate against recurrence The Collis - Conclusion Not necessary in almost all repairs of Giant Paraesophageal Hiatal Hernia! (but learn how to do it so you can be comfortable when you do need it!!!!) Counter Point Collis – just how good is it? Why do you do less Collis procedures today than previously? 86% down to 53% Dai, Q: Dig Dis Sci. 2006 Jan;51(1):105-9 Nason K, Luketich J, Ann Thorac Surg 2011;92:1854 Quotes “ When are esophageal surgeons going to abandon the Collis operation? Having experienced the same results as Dr S….., I have stopped using it for the most part” Pelligrini, C: Discussion: J Gastrointest Surg, 2004; 8:31-39 The Collis - Conclusion Not necessary in almost all repairs of Giant Paraesophageal Hiatal Hernia! Counterpoint Collis – just how good is it? Long Term 150 pts Collis - 14 yr period 85 pts lap – wedge fundectomy 5.3% of all antireflux procedures Good outcomes But 11% esophagitis above the Collis Median follow up 12 months Zehetner J, DeMeester TR: Ann Surg 2014 Conclusion High recurrence rate – not a result of shortening in most cases PEH repairs Role of PEL?? True Shortening is uncommon! Collis is unphysiologic – problems! Not so great LONG term results “Lengthening” the esophagus does not mitigate against recurrence Collis- Laparoscopic Linear Stapler Approach (Wedge Gastroplasty) Data: Summary: Good operation when necessary Question, how often is it necessary? Point #4 Similar recurrence rates whether the Collis is used or not! Point #4 BUT….. Small recurrences are OK! Most asymptomatic, and rarely dangerous We have still made our patients better! Recurrence? Lin, E, Smith C D: J Gastrointest Surg 2004;8:31-39 Distension of the Stomach Fitzgerald RC, GUT 2002, 50:451 What is wrong with the operation?? What is wrong with our patients?? Most recurrences are asymptomatic And the risk of torsion or hemorrhage Is MINIMAL The New OR’s UPMC Short Esophagus John Hayward In the experience of different surgeons there is a wide variation in the number of oesophagi alleged to be too short for reduction of the hernia, and recent reports suggest that they are fewer than was originally thought. Hayward, J: Thorax March 1961: 16(1); 41-45. The Giant Hiatal Hernia • Collis – what, how, and why? • Giant hiatal hernia • Why so many? • Why so many recurrences – Due to short esophagus? – Forces at the hiatus – tissue issues – Does recurrence matter? Recurrence? Recurrence due to: • Shortening?? • Intraabdominal forces Greater in Hi BMI • Inherent weakness at the hiatus • Disruption of the phreno-esophageal ligament
